The technical FIELD

[0001] the Present invention relates to a hydraulic power generating installation made with the possibility of generating power by use of the flow of water.

The LEVEL of TECHNOLOGY

[0002] the Author of the present invention has developed a hydraulic power generating unit, which is disclosed in the source patent literature 1, the generating power using flow of water when installing on a river, artificial streaming channel or similar. The specified hydraulic power generating installation suitable for installation on a small river and on the river the first class.

[0003] Due to the generation of energy, which is performed through the use of hydraulic energy small source such as a river, the hydraulic power generating installation was custom qualitatively new installation, capable of efficient hydraulic power generation with low cost.

[0004] However, the actual use of the hydraulic power generating installation has identified several items for which you want to perform the upgrade. The items for which you want to perform improvement, mainly include the following two problems.

[0005] One of the problems is technical the om service. Because hydraulic power generating unit has hydraulic power generation when installed on a streaming channel with the flow, the turbine will start to rotate immediately after installation and until then, until the water in the river or similar discharged. Hydraulic power generating installation (originally formatted translation in part of application No. 2012113641) the advantage that the generation of energy takes place by means of a stream of water having a natural origin. In this case, periodic maintenance is inevitable to maintain the installation. Up until the time of maintenance came up, maintenance is not performed for any installation. In this case, when performing maintenance, you will need to stop the flow of water or to carry out works on land after lifting hydraulic power generating installation from a streaming channel by means of a crane or similar mechanism. Therefore, a problem arises, namely, that maintenance will be very time-consuming.

[0006] Another problem is the fluctuation of the water level. There is a fluctuation of the flow rate of the streaming channel, corresponding to the period of the irrigation period without irrigation, the rainy season or the dry season. PQS is LCU hydraulic power generating plant is installed in place, in which there is a flow of water, such as river and agricultural streaming channel, an interrupt occurs, to some extent, the flow of water and there are water level fluctuations on the pressure side and low side. In addition, since the amount of energy generated depends on the level of the water on the discharge side, there is a difference in the amount of generated energy in the rainy season, providing a large amount of water, and the dry season, providing a small amount of water. Therefore, here follows a possible problem, namely, that it will be impossible to perform stable power generation.

The PREFERRED embodiment of the INVENTION

[0016] Hereinafter will be described in detail preferred embodiments of the present invention on the basis of graphic materials.

[0017] figure 1 presents a top view illustrating an implementation option hydraulic power generating installation according to the present invention. This document is not represented in figure 1, the generator 4, the pulleys 32,42, the belt 43 and the drive shaft 41 to facilitate visual display of each structure. Figure 2 presents a view in transverse section along the line B-B, are presented in figure 1. There are no gear 54, the movable shutter 5 and the accelerating plate 7 for a clearer image of each structure. On Phi is .3 presents explanatory view in cross section showing the structure of a vertical axis turbine 3, located in the hydraulic power generating installation 1 made simplified for greater clarity, the positional relationship of the rolling shutter 5 and the vertical axis turbine 3. Figure 4 presents full General view of the structure of a vertical axis turbine 3, which is located in the hydraulic power generating installation 1.

[0018] As shown in figure 1, the hydraulic power generating unit 1 includes a housing 2 having a hole 8 for the flow of water, the hole 9 for the water outlet and the duct 25, which provides communication between the bore 8 for the flow of water and the hole 9 to exit the water. The use of hydraulic power generating installation 1 perform according to the figure, the opening 8 for the flow of water is located on the discharge side has over the streaming channel, and an opening 9 for the water outlet is located on its downstream side.

[0019] As shown in figure 2, the hydraulic power generating unit 1 includes a vertical axial turbine 3, which is mounted for rotation in the channel 25 of the housing 2 and contains many of the rotor blades 33, 33, ... (hereinafter simply referred to as rotor blades 33), the generator 4 which generates electric power by receiving the rotational force from the vertical axis of the turbine 3, the movable shutter 5, which is made with what zmoznostjo changes in cross-sectional area And the flow of water, acting on the upper end of rotor blades 33 of the vertical axis turbine 3, upon receipt of openings for the flow of water 8, and the plate 6 to collect water, which performs delay and accumulation of water flowing on the streaming channel, and sends the accumulated water in the hole 8 for the flow of water, when installed by immersion in streaming channel.

[0020] the Housing 2 comprises a top plate 21, the bottom plate 22 and two side plates 23, 23 and contains a hole 8 for the flow of water leading to the pressure side, and a hole 9 for the water outlet opening to the downstream side. The upper plate 21 is made of two arcuate guide grooves 24. The movable shutter 5 is made so as to be movable in the direction of the arrow represented in the figure by means of the direction in the guide grooves 24, provided that the serrated portion 52 (see figure 3) is included in them.

[0021] In the housing 2 is made duct 25, which provides post holes 8 for the flow of water with a hole 9 for the water outlet. The opposite vertical axial turbine 3, 3 are placed in the duct 25. The vertical axis turbine 3 of this variant implementation is the turbine cross-flow, containing the rotating shaft 31 and many of the rotor blades 33. The rotating shaft 31 is mounted for rotation on bearings 26, 26 in the top plate 21 and the lower lip is e 22 (see figure 4). Despite the fact that in the present embodiment, use of the turbine cross-flow as vertical axis turbines 33, 33, alternatives can be used as turbines vertical axis type.

[0022] the Pulley 42 mounted on the drive shaft 41 of the generator 4 is connected with a pulley 32 fixed on the rotating shaft 31, by means of a belt 43. The generator 4 is made for the exercise of power generation when transmission of rotational forces caused by the rotation of the rotating shaft 31 of the vertical axis turbine 3, the drive shaft 41 by means of a belt 43. Each vertical axial turbine 3, 3 are attached to the generator 4.

[0023] the Movable shutter 5 refers to the type of sector gates (i.e., radial gates), in which the shaft acts as the center of rotation of the two arched doors shutter. The shutter is mounted for rotation on the rotating shaft 31 of the vertical axis turbine 3 and includes an arcuate housing portion 51 attached to the rotating shaft 31 by means of bearings 53, 53 and the arcuate toothed portion 52 located on the hull 51. Gear profile, suitable for engagement with the gear 54, formed on the outer circumference of the upper section gear part 52.

[0024] the Plate 6 to collect water, designed to capture and accumulation with pornoi side of the water, the current through the streaming channel, made as one piece or separately from the edge of the hole 8 for the flow of water. In the hydraulic power generating installation 1 of the present invention accumulated water passes into the housing 2 through the opening 8 for the flow of water, the accumulation of captured water through the plate 6 to collect water. Accordingly, the cross-sectional area And flow holes, adjustable rotating shutter 5 is the area of the throttle hole. The flow rate in force on the vertical axis turbine 3 as determined from the area of the throttle hole and the water level H accumulated on the discharge side through the plate 6 to collect water.

[0025] in Addition, the accelerating plates 7, 7 located opposite, as shown in figure 1, is installed in the housing 2. The flow of water in the channel 25 can be accelerated by gradually reducing the area of openings 8 for the flow of water through the accelerating plates 7, 7. Accelerating plates 7, 7 this version of the implementation is made in the form of a sliding sluice gate lifting type. Their vertical lift creates an intermediate space relative to the bottom plate 22, and the water in the duct 25 can be released via the specified intermediate space.

[0026] Hereinafter will be described in relation to figure 5 the operation of the rolling shutter 5 in Hydra is symbolic of a power generating installation 1, performed as described above. Figure 5 provides an illustration explaining the operation of the hydraulic power generating unit 1. Figure 5(a) presents the open position of movable shutters 5, 5, and figure 5(b) presents the closed position of the movable shutters 5, 5. This figure in order to clarify the positions of movable shutters 5, 5 are not depicted accelerating plates 7, 7 and other structures.

[0027] As shown in figure 5(a), when the movable shutters 5, 5 are in the fully open position, the cross-sectional area of flow, i.e. the area of the throttle hole is equal to A. further, the area of the throttle hole indicate with the help And with a numeric index, as the orifice indicate by using the cross-sectional area And flow.

[0028] To move to the closed position, represented in figure 5(b), from the above provisions it is necessary to rotate the two gears 54, 54 in accordance with these directions of arrows as shown in figure 5(a). Then, gear parts 52, 52 which engages with the gears 54, 54, respectively, will move to the Central part along the outer circumference of the vertical axis turbines 3, 3 in the guide grooves 24 in which they are installed, by rotation. When the movement is fully completed, in the morning the upper ends of gear parts 52, 52 will be close to each other. This position is a closed position. In this position, the area of the throttle hole becomes approximately equal to zero, if this is blocked the flow of water passing to the vertical axis turbines 3, 3. Thus, rotation of the rotor blades 33 can be stopped. In this position perform maintenance vertical axis turbines 3, 3, therefore, there is no need to move the hydraulic power generating unit 1 to the surface of the earth by means of a crane or similar. As a result, it is possible to easily perform the maintenance work. During the rotation of the gears 54, 54, respectively, in the direction opposite to the direction of the arrow presented on figure 5(a), after the completion of maintenance work, movable shutters 5, 5 can be moved toward the outer side (i.e., to the side plates 23, 23) along the outer circumference of the vertical axis turbines 3, 3. In addition, the movable valves 5 can be designed in such a way as to change the cross-sectional area of the flow by opening and closing performed by moving in the direction perpendicular to the flow of 25.

[0029] In the hydraulic power generating installation 1 according to the present invention the area of the throttle open is I can be adjusted through the use of movable gates 5, 5, as described above. Based on the availability of openings, it is assumed that the flow rate of water passing to the vertical axis turbines 3,3, will decrease with the reduction of the area of the throttle hole so as to cause the torque reduction efforts are vertical axis turbines 3, 3. However, in fact, according to the present invention mentioned above does not occur. The basic idea of the present invention will be described on the basis of 6.

[0030] figure 6 presents a diagram illustrating the relationship between the throttle opening and the vertical axis turbines 3, 3 hydraulic power generating unit 1. Figure 6(a) the area of the throttle hole presents A1 and figure 6(b) the area of the throttle hole presents A2.

[0031] As depicted in Fig.6(a), the water passing to the vertical axis turbines 3,3, passes through the open part throttle openings, having a square hole A1. Rotary vanes directing the flow of water beyond the stream of water passing the result to the center between the vertical axis turbines 3, 3, are the rotor blades 33a presented on Fig.6(a). Meanwhile, the rotor blades, which mainly contribute to the rotation of the vertical axis turbines 3, 3, are the rotor blades 33b presented on this figure. Therefore, torque Wuxi is their vertical axis turbines 3, 3, depends on the flow rate of water, directly affecting the upper ends of the rotor blades 33b.

[0032] In contrast, according to Fig.6(b), where the area of the throttle hole is set to A2, which is less than A1, by moving the movable shutters 5, 5 in the closing direction, the flow of water passes through the open portion with the orifice A2. In this case, although the area of the throttle hole becomes smaller, the amount of water flowing directly to the upper ends of the rotary blades 33b, remains almost the same. Thus, in the hydraulic power generating installation 1 of the present invention it is possible to obtain a negligible impact on the torque force vertical axis turbines 3, 3, despite the reduction of the area of the throttle hole. Accordingly, it can stably be hydraulic power generation during the adjustment of the water level on the discharge side. The reason for this will be described below in relation to Fig.7-15.

[0033] At all Fig.7-15, except for figure 10, presents the image obtained by simplification of figure 2. On the figures presents the relationship of the accumulated water level on the discharge side, the flow rate and flow velocity of the water flowing from the throttle hole, and the accumulation of water on the pressure side is carried out is carried out by means of a plate 6 for water collection.

[0034] Consider 7 as an example for description, and the flow velocity VI represented by the following formula, where Q1, H1, V1, A1 and g respectively denote the flow rate on the discharge side, the effective difference of water levels, water flow rate, the output of the throttle opening, the area of the throttle hole and the acceleration of free fall.

[0035] V1=√2gH1

[0036] Here, the above assumption is made as excluding local constriction of flow.

Denote the flow rate discharged from the throttle hole, through Q1, the flow rate Q1 is represented by the following formula:

[0037] Q1=A1√2gH1

[0038] Accordingly, if the flow rate on the discharge side and the flow rate of the exit stream of the throttle holes be represented as Q1, the effective water level can be adjusted by adjusting the area of the throttle opening, as shown in Fig.7.

On the other hand, in case of change of flow rate on the discharge side, the effective drop in water level can be maintained constant by adjusting the area of the throttle hole.

[0039] it Should be noted that an important aspect of hydraulic energy generation in the streaming channel is that there is a need to flow from the pressure side and the flow in the eye, manufactured from throttle openings, were equal to maximizing the efficient generation of energy. For example, as shown in Fig, if the flow in Q1, Q3 on the pressure side is less flow in Q2, Q4, output of the throttle opening, the effective difference in water levels H1, H2 will decrease. On the other hand, if Q1 and Q3 more effective drop in water levels H1, H2 will increase.

[0040] In a rare case for a year, the water level in the streaming channel will remain constant. In particular, it is considered normal if the quantity of water intended for agricultural use in the irrigation period of approximately 2-5 times differs from the amount of water in the period without irrigation. In this case, the change amount of water affects the flow velocity V of the water produced from the throttle hole, and effective drop in water levels H.

[0041] the Reciprocal ratio of the change of flow rate on the discharge side with the change of the flow velocity V and the effective difference in water levels H, as well as changing the number of generated energy W=QgH will be described in relation to figure 9.

[0042] the Amount of generated energy W1 for the estimated time is expressed by the following formula: W1=Q5×g×H3. On the other hand, when reducing the flow rate on the discharge side, there will be a reduction H4 and V4 in case Neuve is moznosti adjust the area of the throttle hole.

[0043]Next is a description of the water level in the main streaming channel according to figure 10. On the basis of the main functions of the streaming channel, cross-sectional shape of the streaming channel and the slope of the streaming channel is determined in accordance with the planned amount of water. Usually, define objectives and parameters of the proposed streaming channel and designing the cross-section of the streaming channel to meet the parameters, that is, to ensure that planned expenditure flows (i.e., the maximum and minimum costs) projected target streaming channel, and the depth of the water is Not scheduled flow (i.e. the maximum value). Usually, the value b set equal to 80% values At depth. The cross-section of the streaming channel and the slope of the streaming channel is determined on the basis of the manning formula and formulas Cutter, which is the hydrological formulas. Typically, the flow rate of the streaming channel design so that the average flow rate was approximately 1.2 m/s to 1.5 m/sec. Additionally, typically the flow rate of the streaming channel design so that it is increased toward the downstream side. A significant factor in generating energy in the streaming channel is the use of energy generating equipment while maintaining functions of the streaming channel.

[0044] the Value specified above will be explained in respect 11. Figure 11 presents the situation in which the effective water level H, the flow velocity V and the flow rate output flow Qb of the throttle holes obtained in the presence of flow rate Qa from the pressure side, the upper water level Ha and the area A of the throttle opening. The upper water level is the most important condition to maintain the functions of the streaming channel. It is assumed that the water level will not exceed the maximum allowable water depth Hb. Increasing the height of the top of the streaming channel is required, if necessary, increase energogeneruyu.

[0045] Next, in relation to Fig will be described hydraulic power generating installation in the period of rising water levels, and during the lowering of the water level without adjusting the area of the throttle hole. In the period of rising water levels, flow rate +Qc obtained by using the upper level of the water He greater than Hb, shimmers through the plate 6 to collect water and is not used in energogeneratsii. Accordingly, it is envisaged that the upper water level during the period of rising water levels should not exceed Hb. On the other hand, during the low water level of the upper water level will Not be reduced, and therefore, the effective difference in water levels H also decreases accordingly. Accordingly, the efficiency of energogeneruyu the hydraulic power generating installation will be reduced due to double-dip, namely reducing the number of generated energy Qa and reduce H to adverse conditions in which the total amount of generated energy will decrease.

[0046] Next, description will be made regarding Fig and 14 with regard to the hydraulic power generating installation of the present invention can change the upper water level by adjusting the area of the throttle hole, in these times of high water level and low water level. At first we shall consider the period of low water level presented on Fig, in the case of change of throttle openings from A1 to A2, theoretical amount of generated energy will be respectively W1=Qa×g×H1 and W2=Qa×g×H2. Of course that may be obtained from the amount of generated energy W2 greater than W1. The reason can be obtained the amount of generated energy W2, is that the area of the throttle hole can be changed from A1 to A2. That is, in this case, you just need to reduce consumption, the exit stream of the throttle holes in order to increase the surface of the water until the water level, which can be supported functions of the streaming channel. That is, you just need to move the movable shutter 5 in the closing direction in order to reduce the area of the throttle hole. Dotech long as through the square A2 of the throttle opening can be supported H2, can be obtained the amount of generated energy W2.

[0047] Similarly, since the area of the throttle hole can be increased so that flowing over the edge of the flow rate +Qc in the period of rising water levels can be used to generate energy, the amount of generated energy will increase. In this case, you just need to increase the flow rate of the exit stream of the throttle openings to allow water level which prevents the flow over the edge of the flow rate +Qc. That is, you just need to move the movable shutter 5 in the opening direction to increase the area of the throttle hole. In this case, the number of generated energy are W3=Qa×g×H3 and W4=(Qa+Qc)×g×H4. Due to the above, the maximum amount of generated energy increases without any overflow of the stream caused the upper water level.

[0048] As described above, in the hydraulic power generating installation of the present invention, since the area of the throttle opening can be regulated by opening and closing of the rolling shutter, it is possible to increase the amount of generated energy without reducing the efficiency of the hydraulic power generation and to provide the function of adjusting the flow rate. In addition, since the flow of water, the current to the vertical axis turbine can be stopped by complete closure of the rolling shutter, it is possible to easily perform the maintenance work.

[0049] Next will be considered the case when the flow stream over the edge cannot be prevented only by increasing the area of the throttle hole with a significant increase in the amount of water. In this case, it is also possible to use a structure in which regulating the flow rate of the opening part is made in the plate 6 to collect water, as shown on Fig, to release excess water through the opening portion on the downstream side. Alternatively, you can also use a structure in which the door is arranged to open and close (not shown), mounted in the plate 6 to collect water in order to release excess water from the pressure side of the streaming channel on the downstream side without passing through the duct by adjusting the degree of opening of the door, configured to open and close in accordance with the change of water level in the streaming channel.

[0050] In the above hydraulic power generating installation 1 are vertical axial turbine 3, 3-axle type. However, it is also possible to use a vertical axial turbine 3 uniaxial type as shown on Fig. N is Fig presents an open position and a closed position rolling shutter 5 in the hydraulic power generating installation 1, which is the vertical axis turbine 3 uniaxial type. On the figure to denote the same functional and structural elements are used in positions similar to the positions for the hydraulic power generating unit 1. Therefore, the structure and operation is almost the same as the above, and their detailed description will not be presented.

[0051] In this document, without limiting the foregoing, for example, the structure for placing gear on the downstream side, as shown in Fig, can be used as patterns made with the possibility of opening and closing, rolling shutter 5.

[0052] In the hydraulic power generating set to 1, the movable shutter 5 includes a semi-circular top plate 55 of the main hull 51, having a toothed profile made on its periphery, in contrast to the above variant implementation. In addition, as shown in Fig(a), part of the upper plate 55 is attached to the main hull. Part of the upper plate 55 with a toothed profile is in mesh with the gear 54 so that the upper plate 55 is rotated with the rotation of the gear 54 through mutual engagement. Thus, similar to the specified case implementation is provided by the opening and closing of the rolling shutter 5.

[0053] In the previous embodiment, use the handle 57 to effect the rotation of the gear 54. That is, the rotation of the gear 54 will be carried out by the rotational motion of the plot grip 58 of the handle 57, the end of the handle 57 is attached to the upper end of the rotating shaft 56 of the gear 54.

[0054] This document is not limited to the above implementation options and different ways of implementation, as described below, can be adapted to the present invention without going beyond the scope of the present invention.

[0055] for Example, the structure of the plate 6 to collect water can be changed depending on conditions on the streaming channel on which you are installing the hydraulic power generating unit 1. As shown in Fig, when installing a hydraulic power generating installation 1 wide streaming channel, both end section of the plate 6 to collect water attach to the walls of the streaming channel by means of mounting brackets 61. In this case, in addition to the capture and collection of water flowing through the streaming channel, plate 6 for water collection also includes attaching and fixing the housing 2 on the streaming channel.

[0056] Next, as shown in Fig, when installing a hydraulic power generating installation 1 on the narrow streaming channel, both end area of the housing 2 directly attached to the walls of the streaming channel by means of mounting brackets 61. This is the case, in the function of the front plate 27 of the housing 2 is provided as the locking function, and the function of the plate 6 to collect water.

[0057] in Addition, as shown in Fig, when installed on a narrow streaming channel without differential, plate 6 to collect water raises the water level on the pressure side and forms a pressure in the streaming channel through the recovery and collection of water flowing on the streaming channel. The above ensures that the positional energy generated by the pressure acts on the vertical axis turbine 3 in the housing 2.

[0058] in Addition, in the case of a wide streaming channel with differential levels presented on Fig, more energy can act on the vertical axis turbine 3 through the use of the pressure of water flowing down on the plot of the difference of levels, during installation of the housing 2 from the lower side of the differential.

[0059] moreover, in the case of installation on a wider streaming channel, the intake of the receiver 62 may be set on a plot of differential levels of streaming channel presented on Fig. In this case, you just need to attach the plate 6 to collect water to the water intake hole 62a water receiver 62, and also to attach the housing 2 hydraulic power generating installation 1 to be the outlet 62b. In this case, the plate 6 for water collection is made in the form of A plate for collecting water located perpendicular to the flow in the streaming channel, or in the form of a plate 6B to collect water, which is located at an angle to the stream in the streaming channel. Proceeding from the above, the plate 6 to collect water performs the function of collecting water flowing from the discharge side to the intake of the receiver 62, located in the center, in addition to creating pressure by raising the water level on the discharge side.

[0060] in Addition, there is also the possibility that the accelerating plate 7 as additional functions are implemented by producing a function that will be described below and is not significant for the hydraulic power generating plant 1 of the present invention.

[0061] That is, in the hydraulic power generating installation 1 presented on Fig accelerating plate 7 made in the form of panel shutter lifting type, and the outlet openings 28, 28, through which the water passes and is made in the side plates 23, 23 on both sides of the housing 2. Accordingly, when the accelerating plates 7, 7 are raised in a vertical direction, provided that the movable shutters 5, 5 are closed, as shown in the figure, the water in the duct 25 will be produced outside of the housing 2 through the passage through the outlet opening 28 of the intermediate space with respect to the bottom plate 22. Thus, even if the hydraulic power generating installation is ka 1 remains installed on the streaming channel, the maintenance components, such as vertical axial turbine 3, which is located in the housing 2 and the generator 4 can be performed without stopping the flow of water in the streaming channel.

[0062] in Addition, it is also possible to use the structure presented on Fig, as a modified example of the accelerating plate 7.

Accelerating plate 7 is rotating bolt with the door 71 of the rotary type, is arranged to open and close. The door 71 is made with the possibility of opening and closing, is located in the center of the accelerating plate 7. The door 71 is made with the possibility of opening and closing, mounted for rotation in the direction of the arrow shown in the figure, around the vertical shaft 72. In this case, when the door 71 is made with the possibility of opening and closing, accelerating plate 7 is open, provided that the movable shutters 5, 5 are closed, the water in the duct 5 can be released from the housing 2 through the outlet 28. In this document, without limiting the above structure, accelerating plate 7, having a releasing function, can be used rolling shutter (not shown) single-acting or double-acting, capable of being opened and closed in a horizontal direction.
