The present invention relates to a hydroelectric device for producing regenerative and renewable energy, as follows in accordance with the restrictive part of claim 1 of the claims.

The present invention also relates to the hydropower system for producing regenerative and renewable energy, contains many such devices.

For more than a hundred years water use for energy production. Each of the existing hydroelectric power plants designed in accordance with the water flow and slope, depending on which are used in a turbine or water wheel Pelton units, Francis or Kaplan. Also known turbine located in channels or pipes, as well as the so-called hydraulic or Archimedes screw.

Reasons for the further development of these well-known options such as hydraulic turbines and water wheels were not years or even decades.

The use of these turbines of different types is dictated, on the one hand, as indicated above, water consumption, and on the other hand, the slope and back pressure. So, for example, the turbine of the Pelton units are used in places where the slope and the high pressure and the flow of water is small, and Kaplan turbines put into operation in places where the slope is small and the flow of water is the medium. However, when both the slope and the water flow is small, Urbina these known types cannot be used.

In addition, when the water flow becomes or other changes, it also creates problems for turbines of these known types, which are designed for relatively limited range of flow rates. If the water flow is too large or too small, the turbine could not operate.

The upper limit of the efficiency of the turbines of this type, some of which have existed for a very long time, has already been achieved, leaving the possibility of further increase, which is not conducive to appropriate further developments.

And that's not all, because the spiral increasing cost of fossil fuels and their limited availability has led to the fact that over the last codes were observed urgent need for the implementation of energy from renewable sources, which have the advantage that it does not contribute to the so-called greenhouse effect.

That is why the basis of the present invention lies in the task of developing a hydropower device for producing regenerative and renewable energy, which differs, in particular, those that are compatible with the environment and is of simple construction and easy to install, while being extremely effective in spite of the changing conditions of water availability.

In addition, the invention is also directed to RA is the development of systems with such devices to obtain the corresponding modular configuration.

Hydropower device for producing regenerative and renewable energy includes at least one generator for generating electric energy and drive shaft, which is connected to the generator and which contains many blades, driven in rotation by the flow of water. By means of the blades, located offset relative to each other and along the drive shaft, the pressure of flowing water is used in an optimal way, which leads to a surprisingly high rotation speed of the driving shaft and a large torque.

In particular, in accordance with the invention are achieved by the rotation speed and torque of the device, which are less susceptible to change than conventional turbines types and known systems.

From U.S. patent 1903545 known device for converting kinetic energy from the water flow. The described device has a drive shaft, containing a number of blades extending at least partly, in passing water, provided that water into rotation, and the blades are offset circumferentially relative to each other along the drive shaft. At the end of the drive shaft turns the kinetic energy. In this construction the blades are mounted at a fixed angle relative to the drive shaft. However, the efficiency, the achievement of aemy the device in the process of converting the kinetic energy, derived from the flow of water, small.

Hydropower device in accordance with the invention, intended for producing regenerative and renewable energy has many advantages, including:

the simplicity and ease of installation without the construction works;

the ability to provide the main power in the region because of its location close to the power consumer;

universal and - if necessary - automatic adaptation of the device to the existing flow settings, ensuring thus the optimized response of the device in accordance with the invention;

power generation without compromising the environment;

the possibility of optimizing the dimensions of the device for the required supply, such as specialized their job for installation in remote settlements, etc.;

adaptability of the device to any stream of water and a variety of flow conditions;

the production of energy without harmful emissions.

As a benefit it should be noted that the blades attached configuration of the reflective type, i.e. they have a configuration similar to the aircraft or propeller screws, which by definition are for traffic message (for example, aircraft or marine vessel), and the reflectors floor which indicate the power flow from the surrounding substances. The term "reflective type" should be understood as denoting the reflectors, which may contain one, two or even more blades.

In accordance with the invention, the installation angle of the blades is mainly controlled from the blades to the blade to optimize the use of the passing stream, and the installation angle of the blades along the drive shaft may vary from blade to blade.

In addition, as the benefits it should be noted that the gap between the blades is adjustable in the longitudinal direction of the driving shaft, so that it can be different or may not be permanent.

An additional advantage is that the installation angle of the surface of the blade is adjustable relative to the surface of the drive shaft that leads to the implementation of the surface of the blade with the possibility of positioning in accordance with the pressure of the incoming flow, and in this case may vary along the length of the drive shaft. The positioning can be performed under computer control, or by using mechanical, Electromechanical, pneumatic or hydraulic means.

The particular advantage of the device according to the invention is that it can be optimally adapted to the existing "hydropower chart by changing the installation angle love the TEI, with the benefit of using this control from your computer. Hydropower chart may reflect the following parameters: water flow (m3/s), slope, energy flow and dynamic response to back pressure.

If necessary, hydropower chart record the length of the drive shaft by means of suitable sensors, and thus the angle of the blades adapted to changes in hydropower chart, optimizes the efficiency of the device in accordance with the invention.

Thanks to the planting of the blades on the drive shaft with the possibility of removing the worn or damaged blades can be quickly replaced with new ones.

In the first preferred embodiment, drive shaft directly connected to the generator, transmitting power directly to him. In the alternative, the drive shaft may be connected to the generator through a suitable gearbox.

Thanks to the installation of the drive shaft in the frame, for example, a rectangular shape is achieved all the benefits of simple, compact construction, designed for easy transport and installation. Also achieves the advantage that the generator can also be installed on the frame.

An additional advantage is that the frame is made in polozek the volume or fully closed chute, as a result, controlled the direction of the water.

Because the used the device can be placed horizontally, inclined or even vertical, it has the advantage of universal applicability. It can be put into operation or in the event the normal water flow in the river or sea current, or in the case of an inclined or even vertical falling water.

To achieve the advantages of the device according to the invention it can be located preferably in the middle between the two floats and preferably on a leash. A huge benefit of this is that the device floats in the water, and it makes possible the placement of the device in accordance with the invention in flowing water to generate electrical energy from the flow. In addition, it has the fundamental advantage that the use of the device is not dictated by the water level, because the device should this level, thereby ensuring its use even in high water. For proper tying you to adapt the device to change the direction of flow of water, without the additional funds.

This is further supported by the fact that the device mainly contains a controlled steering node.

Updat the additional advantage lies in the fact, the device contains guides or inkjet tubes that direct the flow of water on the outer ends of the blades, optimizing the impact of the flow on the blade.

An additional advantage is that the drive shaft that the blade is installed with adjustable height, resulting depth of the blades in the flowing stream of water is regulated, and its benefits can be changed along the drive shaft. Height adjustment can with benefit be achieved by rotation of the drive shaft, for example, by means of manipulators with a rotary degree of mobility that is installed on one end.

As mentioned above, the device for generating energy in accordance with the invention leads to a considerable speed, which can cause vibration. Therefore, the driving shaft mainly revolves in bearings located at both ends, and at least one additional location, such as two to five locations between the ends, resulting, on the one hand, the whole device becomes rigid, and on the other hand, rotation of the drive shaft to a greater or lesser extent exempt from vibrations.

As the bearings of the driving shaft is provided mainly self-lubricating, seal, oscitancy for the entire period of service, and made of plastic or ceramic bearings or ball bearings, as they are, on the one hand, have a great life, but on the other not exposed to the risk of silting passing the water stream.

An additional advantage is that the drive shaft is designed as a splined shaft and bearing each blade - like spline bearing. This allows you to retrieve the landing of the blades on the drive shaft, which is simple, efficient and easy to control, with a simultaneous guarantee stable operation of the drive shaft for smooth transmission of power to the drive shaft.

The flowing water carries not only debris such as driftwood, wood or leaves, but can also tighten the fish, and this is the reason why the device is protected from the front protecting from debris shield, preferably of the type pointed plough, to prevent the ingress of debris into the device in accordance with the invention, a protection which can be enhanced by using a mesh fence that surrounds the device.

Specifically preferred configuration of the blades is designed so that every two blades that are offset from each other by 180, form a common tubular element containing a cavity which is enclosed fluid medium. With this arrangement, fluid fills the cavity is fully, and preferably, essentially, only half of the cavity, which has a symmetrical configuration of the two halves of the blade. When the cavity is located horizontally in both halves of the cavity is essentially the same amount of fluid. Upon further rotation of the blades of the fluid suddenly accelerated under the action of gravity, forcing further rotation of the blades. When the tubular blades a lot, achieved a constant speed and, in essence, a constant torque. Although the fluid is mostly water, you can use any other suitable fluid medium.

This configuration is particularly useful when the water flow is weak, so that it is possible to select only a small number of driving energy, which may not cause rotation of the blades.

Another objective of the present invention is to develop a hydropower system for producing regenerative and renewable energy, characterized in that it contains a number of devices according to any one of claims 1 to 22 claims, adjacent and/or near to each other and/or one above the other.

Therefore, one such system can be run unit to make it versatile and adaptable to the conditions of use, such as the width of the river, the asset is th length, the depth of water, etc

In one particular embodiment, the drive shaft of the device is also a universal interconnected, thereby making the drive generator as a whole.

The same parts shown in the drawings, indicated in the following description, the same positions.

In accordance with figure 1 shows the hydropower device for producing regenerative and renewable energy in accordance with the present invention in a first variant implementation, demonstrating its basic layout. As shown in figure 1, the device 1 in accordance with the invention comprises a generator 3, which may be connected via a gearbox 4 and strap 6 with the drive shaft 5.

Drive shaft 5 is located in the middle of the frame 7, having a rectangular configuration with two side elements 9 and two lateral elements 11. In addition, the frame 7 contains additional part 12, which is equipped with the gear 4 and the generator 3.

On each end of the drive shaft 5 rotates in bearings 13 mounted on the transverse element 11.

As shown in figure 1, the frame 7 is placed on an elongated groove 15, and the driving shaft 5 is located in the region of the upper side of the flow channel 17, is made in the groove 15.

As can be seen from figure 1, along the drive shaft also has many reflectors 19 in the form of a propeller. Each reflector 19 has two blades 21, the offset is passed relative to each other by 180, which are rotated by the water flow (see figure 2). As already mentioned, the reflector 19 can also contain only one blade or more than two blades 21.

The blades 21 and the reflectors 19, respectively, are located along the drive shaft 5 with offset. In other words, the blades 21 of one of the reflector 19 is rotated relative to the blades 21 of the next reflector 19 adjustable angle for optimal power flow from the current environment.

In accordance with figure 2, the device 1 is tilted into the groove 15 so that the flow of water 23 flowed from the inlet 25 at the top down the chute to release 27. This flow of water will cause rotation of the blades 21 on all of the control shaft 5, which by means of straps 6 and unit 4 performs the drive generator 3.

In accordance with figure 3, the upper water level 29 23 is located below the drive shaft 5, so that only some of the blades submerged in water 23.

Flow channel 17 is formed of a round channel, open at the top.

In addition, figure 3 schematically shows how you can move up or down the level layout of the drive shaft 5, which, as shown in figure 3, is the lowest level.

In accordance with figure 4 depicts a schematic side view of the device 1, in accordance with the invention, the prisoner in the pipe and on the slope, showing how water 23 the dt through the pipe 35, having a circular configuration and preferably made of sheet aluminum. Inside the pipe 35 is enclosed drive shaft with blades (not shown).

In accordance with figure 4 it is obvious that the flow of water 23 completely fills the cross-section of the inlet pipe. In this embodiment, the flow of water can circumnavigate the generator 3. Alternatively, it is possible layout of the drive shaft universal connection with the generator located on the outside (not shown).

The tube was installed on the supports 36, which are located essentially at equal distances from each other. Below the outlet pipe is the exhaust tank 37.

As shown in the embodiment depicted in figure 4, the cross section of the pipe is completely filled with stream water. But the device in accordance with the invention will also produce electrical energy even when the cross section is not completely filled with stream water, while a state of complete filling of the pipe cross section flow may come later, or not occur at all.

In accordance with figure 5 illustrates schematically the means for positioning the blades 21 of the cover 19 on the control shaft 5.

To achieve the effect of each blade 21 is installed in the support 41 can be rotated in the direction indicated by the double arrow 3, so each surface 22 of the blade can be set at an individual angle relative to the water stream.

In addition, you can move the reflectors 19 along the drive shaft, as shown by the double arrow 43. The possibilities shown in figure 5 are only examples, and shows the layout of the individual reflectors 19 may not correspond to their actual installation, with double arrow 45 indicates the possibility of turning vanes, for example, as shown in figures 1 and 2.

This option is optimal installation achieved in accordance with the invention, leads to an optimal hydrodynamic characteristics of the driving shaft with the additional possibility of using not only almost identical blades 21, as shown in figure 5, but also different blades having a different surface, which allows to optimize the device in accordance with the invention.

In accordance with 6 depicts a schematic view in perspective of a variant of implementation of the construction of the driving shaft 5, the characteristic of which is grooved shaft 40 having longitudinal slots, which is clear from Fig.7 that illustrates the execution on the form of spatial detail. Supporting element 41 is made of a split with two shells 47, each of which has a splined inner profile, cooperation is moswaane slotted slotted shaft 40 to accept the clip.

Each of the ring 47 is inserted by sleeve 48. With this arrangement the axis of the bushings 48 are aligned along one line so that the blades 21 are arranged offset relative to each other exactly 180 degrees. Installation sleeve 48 within the grooved profile, exactly consistent with the splined profile of the coupling 49 each blade 21. It is guaranteed spline connection provides the location of the blade 21 with the possibility of rotation on demand, thus making a very simple fastening of a pair of blades 21 are offset circumferentially relative to adjacent pairs (adjacent pairs) by fixing the shells 47 around the splined shaft 40 with an offset around the circumference. To attach the shells 47 to each other and respectively mounting sleeves 48 to the shells are conventional fasteners 51, containing the nuts and bolts.

In accordance with Fig shows a front view, a hydropower device for producing regenerative and renewable energy in accordance with the invention in an additional variant of its implementation.

Unlike the implementation shown in figures 1 and 2, the device 1 in accordance with the invention is not in the gutter and on the pontoons or floats 61, floating on the water surface. Floats 61 are predominantly FAL 63 in the form of tie ropes, giving the float 1 freedom of semioriental in the direction of water flow.

As is evident from Fig, you can set the level layout of the drive shaft 5 together with the blades 21, as shown by arrows 65.

In accordance with figure 9 depicts additional preferential variant of the proposed device 1 according to the invention, illustrating the ability to bind him, for example, to the corresponding retaining bars 69 on the dam 67 by means of respective locking lugs 71 and 73. The retaining bars 69 are attached to the dam 67 suitable fasteners 70.

As evident from figure 9, the blade 21 is immersed in the water 23 to some extent. When the water level 29 is changed, the device 1 in accordance with the invention can accordingly move up and down, as shown by the double arrow 75, which allows to achieve the optimal performance of the device in accordance with the invention.

Alternatively, the device in accordance with the invention can also be installed with the possibility of rotation on the respective manipulators (not shown), which, in turn, mounted to rotate on the dam. This makes possible very simple ways and means how to set the depth of immersion of the blades 21 in the water 23, and - in contrast to specify a constant depth of immersion of the device in General, if this wish is Ino, in order to adapt it to the existing water level 29 may - changing.

In accordance with figure 10 depicts an implementation option, similar to that shown in figure 9, but now equipped with floats 61, secured to the front protecting from debris shield 81, preferably having the form of a pointed plow. Garbage arriving in the direction of flow (arrow 83), removed the side shielding from the debris shield and therefore does not enter the space between the two floats 61. For extra protection, especially from fish, you can provide network 84 below Poplavko 61, and where necessary - and even behind it (not shown).

To take drifting debris, additionally provided with round reflectors 85, floating on or near the water surface, which preferably can rotate in the direction of flow, resulting in the incoming debris located on the surface of the water could bypass the device 1 in accordance with the invention.

In accordance with 11 shows a device 1 in accordance with the invention in an additional variant of its implementation with the same version of the implementation, shown in figure 1, the frame 7, it is obvious that between the individual pairs of blades 21 are respectively provided between. Although he is shown to be essentially constant, W is the success it is possible to provide for different periods.

In addition, for the drive shaft 5 with a minimum of vibration provided by additional bearings 87, connected with the frame 7 and the side elements 9 crossbars 89.

In accordance with Fig shows a device 1 in accordance with the invention in yet another variant implementation, enclosed in a pipe 77, similar to that shown in figure 4, while the supports 79 are used to install the whole device. Pipe 77 may be positioned horizontally, with the water 23 runs underneath the pipe 77 and the side of it, forming a duct for fish.

When the pipe 77 is inclined, the space 91 under the pipe 77 can be shaped configuration rebodying.

In accordance with Fig shows an additional variant of the device 1 in accordance with the invention similar to that shown in figure 4, but now with the generator 3 is located above the pipe 35, and the support 79 is made adjustable in height, as shown by arrows 93.

Used straps can be flat, V-shaped or toothed belts.

In accordance with Fig note that it depicts a perspective view of the device in accordance with the invention in a variant implementation, calling for pipes and similar to that shown in Fig, but showing how the driving shaft 5 and the pipe 77 is installed in n the existing frame 95 and as two hours 97 supporting frame may form an angle essentially 90 degrees.

In accordance with Fig-17 shows a device in accordance with the invention in an alternative implementation. On Fig presents a perspective view, on Fig - front view, and Fig - side view. In accordance with figa-18C shown in an enlarged scale two blades 24 screw, offset relative to each other by 180, together forming a tubular profile 26, which is made elongated cavity 28. This elongated cavity 28 is sealed from the environment and contains the fluid 30, preferably water, which fills the cavity 28 is not complete and, in fact, only half. When the blades 24 pairs, forming the tube section 26, are rotated from the horizontal position shown in figa, in which the fluid medium 30 is essentially uniformly distributed in the cavity 28, to one side, as shown by the arrow 32, the fluid 30 is suddenly moved, falling under gravity in a part of the cavity (see fig.18b), which leads to a sudden application of torque to the respective blades 24. On Fig shown in its lower position filled cavity 28, which is again rotated to the position shown in figa, etc.

In accordance with figa-19 (C) shows the variation of the variant implementation, is provided on Fig-18C. On both sides and both ends of the blades 24 is provided by the edges 34 of the type reflectors, allowing you to get even better surfaces of the blades, especially when poorly flowing water.

As can be seen from the spiral layout shown in Fig, this abrupt placement causes the rotating drive shaft 5. It should be understood that the dynamic characteristics of the device lead to the fact that rotation of the drive shaft 5 need only a small energy from the outside, and considering the kind of performance and is suitable in particular for use in poorly flowing water.
