In General, the invention relates to energy conversion system, in particular to the energy conversion system that is designed to convert the energy of tidal currents into electrical energy.

Renewable energy has become an important part of energy production in the world. Today, however, the energy of this kind is only a small part of the energy produced, but this part is increased. In particular, Ireland, acting in accordance with the recommendations of the Kyoto Protocol, also intends to increase renewable energy already using many methods and if you are going to expand their list in the future.

On our planet, in particular its oceans, there is a significant force of attraction of the moon and, to a lesser extent, the Sun. This force of gravity during the rotation of the Earth twice a day moves billions of gallons of water, a process known as tidal currents. For decades people have used this energy where the height of the tide was sufficient to recoup the construction of a tidal dam across estuaries or in another suitable place. In the full tide gate dam are closed, and the water passes through the turbines, generating electricity. Cost-effective this system can be only when the produced energy compensates significant satr is you on the construction of the dam.

The drawings in figures 1 to 7 illustrate a first variant implementation of the power conversion system, in General, marked 10, used to convert the energy of tides into electricity. The system 10 includes a wall 12, which in the process is suspended below and across the mass of water is 18, and in the shown embodiment, the wasp is estline this mass of water is 18 held in the channel 16. In a preferred embodiment, the wall 12 can obstruct a substantial portion of the width of the channel 16 in order to achieve maximum effectiveness of the system 10, as will be shown in detail hereinafter. On each side wall 12 is connected with a pair of transducers 14, as shown in Fig.6 and 7, and in the preferred embodiment, the transducers 14 are installed on land along the banks of the channel 16, specially installed inside buildings 34. The system 10 is adapted, as will be shown in detail hereinafter, to convert the energy tide of the mass of water is 18 into electrical energy, using functionally related partitions 12 and inverters 14.

As shown, in particular, figures 1 and 2, in the present embodiment, the partition wall 12 is formed near the sails 20, each of which is installed in a suitable frame 22, and each sail is made from a material with the appropriate properties. Since the partition wall 12 and, therefore, the sail 20 is typically immersed in salt water and when the work affected by a considerable force, it is desirable that the sails 20 were made of a material possessing the necessary strength, flexibility, and non-polluting. Examples of such material may serve as aramids, polymers, carbon fiber, 100% nylon and other Wall 12 along the edges of the of rtraline to her employees support the top rope 24 and the bottom rope 26, which, in a preferred embodiment, the woven steel fibers, or any equivalent. The upper and lower cables 24, 26, together with various additional elements, described below, are designed to maintain the configuration and orientation of the partitions 12 and to ensure the effective transmission acting on the partition wall 12 of the forces on the probes, as will be described later.

In order to partition remained hanging in the channel 16 and did not sink to the top rope 24 along its length attached a few buoys 28. The weight of the partitions 12, together with the weight of the bottom rope 26, provides an essentially vertical arrangement of the partitions 12. However, depending on the operating conditions of system 10 may require attaching to the bottom rope 26 or, alternatively, to the partition of additional ballast (not shown). Each buoy 28 attached to the top rope 24 tethered by the cable 30, the length of which in the shown embodiment, is approximately 10 m, providing accommodation partitions 12 at a depth of 10 m below the surface of the mass of water is 18. This ensures that the majority of vessels (not shown) can pass over the partition 12, not touching her. Thus, since the partition wall 12 is also attached to the onshore converters 14, stretched across the channel 16 of the wall 12 is going to be to influence the tidal flow of water masses 18.

Thus, as shown in figure 2, as the tide in the direction of arrow A, each sail partition 12 is inflated in this direction acting upon it by hydraulic pressure, and the corresponding frame 22 holds the sail 20 is inflated in such an orientation. In the preferred embodiment, each frame 22 is located at an angle of about 45° to the direction of tidal flow, although this angle may be changed, depending on the working conditions and requirements of the system 10 energy conversion.

Thus, it should be understood that each sail 20 acts as a sail of a sailing vessel (not shown)that creates a force directed transversely to the direction of tidal flow, as shown by the arrow In figure 2. This force pulls the whole wall 12 across the channel 16 in the direction of the arrow C. the Phase of this movement is illustrated by figure 1. On figa shows the position of the partition 12 at the moment when the movement begins tidal flow, figb partition is in the middle of the channel 16 and on FIGU partition already reached the opposite shore of the channel 16, to the moment when the direction of tidal flow reverses. This movement across the channel 16 is provided due to the additional length of the top of the rope 24 and the bottom of the rope 26, which are drawn from the Converter 14 when Perigord is 12 away from him. Created by the partition 12 a force in the direction of the arrow C, and is converted by the corresponding Converter 14 into electrical energy, as will be described later. Formed on the opposite side of the partition 12 sagging of the top rope 24 and the bottom of the rope 26 is selected by the Converter 14, in the direction which moves the partition wall 12, which, as will be described later, prevents the deviation of the septum 12 from the position transverse to the direction of tidal flow, shown by arrow a in figure 2. However, as shown in figa, as a result of exposure to the partition 12 strength of tidal flow occurs some bend it. It is desirable to reduce this bending to a minimum in order to keep the transverse orientation of the partitions 12 relative to the direction of tidal flow.

When converting the direction of tidal flow, which happens every 6 hours, every sail, thanks to its flexibility, is inflated in the opposite direction, using as a support fixed to the frame 22. As the frame 22 is, in the preferred embodiment, an angle of about 45° relative to the direction of tidal flow, each sail 20 will have approximately the same configuration and orientation, regardless of the direction of tidal flow. When the direction of Mgr the main flow will change in opposite phases and shown in fig.la-when the partition will move across the channel 16 from right to left. As shown in figa, the partition wall 12 and the upper and lower cables 24, 26 with slight pull in the opposite direction under the action of the attractive force of the flow. For securing the said reverse motion of the partition 12, the operation of the converters 14 on both sides of the partition 12 must also be transferred in the reverse mode, as will be described later.

In order to achieve maximum generation for each passage walls 12 across the channel 16, it is desirable that the partition wall 12 has passed across the channel 16 the maximum possible distance. This is achieved by changing the number and size of the sails 20 forming the partition wall 12. It is obvious that the greater the number of sails 20, the more developed by the partition 12 power and the more produced electricity. As shown in figure 4 and 5, the shape of the sail 20 and, hence, the shape of the surrounding frame 22, can be changed to make the system 10 performance objectives. Obviously, the larger the sail 20, the more developed the strength, but also more real power flow, and thus pulling the partitions 12 in the direction of tidal flow. In the preferred embodiment, each sail 20 is attached to the corresponding frame 22 several them of the fastening elements with the possibility of withdrawal, what is repair or replacement of damaged sails 20.

Next, with reference to Fig.6 and 7, a description of the method of transformation created by the partition 12 power into electricity. On each side of the partition 12, the upper rope 24 and the bottom rope 26 is attached to the respective transducers 14, identically arranged and working. It will therefore be sufficient to describe the workings of one of the converters 14, in this case, the inverter 14 is connected to the top rope 24. Each pair of transducers 14 is located within a suitable building 34, previously mentioned. The main component of the Converter 14 is a drum 36, on which is wound around and attached to the top of the rope 24. The drum 36 is mounted on a shaft 38, on the one hand connected with gear 40. The gear 40 is serially connected with the second gear 42, which, in turn, is connected to the generator 44, the generator 44 may be directly connected to the public grid, or to the appropriate drive (not shown). Of course one should keep in mind that instead of the gear 40 and the second gear 42 may be used a single reducer (not shown)or any other equivalent.

Thus, when the partition wall 12 begins to cross the channel 16, the upper rope 24 (and lower the rope 26, connected with osadnik Converter 14) is pulled out of the building 34, when the drum 36 rotates around its axis 38. However, due to the low velocity of the partitions 12 across the channel 16, the rotation of the drum 36 is fairly slow, so attached to the drum gear 40. Now, during the rotation of the drum 36 for winding with a top rope 24, the gear 40 causes the rotation of the second gear 42 with higher speed, which, in turn, rotates the generator 44, which generates electricity.

When the direction of tidal flow reverses, begin to generate electricity two transducer 14 from the opposite side walls 12, as described above, and two of the transducer 14 in the direction which moves the partition 12, now used for tensioning both sagging rope - top rope 24 and the bottom of the rope 26. To do this, each Converter 14 includes a motor 46 (not shown in the Converter 14 to the right of figure 6 and 7), which, in this embodiment, shown installed on the opposite side of the drum 36. The motor 46 is used to rotate the drum 46 in the opposite direction for winding sagging of the cables 24, 26. Since the converters 14, in particular on the drums 36, high impact load, in the preferred embodiment, each reel is attached to the ground through the m frame 48 or its equivalent. It is clear that when the winding of the cables 24, 26 back to the corresponding drum 36 consumes energy, but this energy consumption will be significantly less than the energy produced by the system 10, allowing the resulting energy balance of the system 10 will be positive.

Also keep in mind that as the cables 24, 26 retracted from the corresponding transducer 14, it should automatically connect additional buoys 28, so as to maintain the partition 12 to the desired depth as it moves across the channel 16. This can be done in the usual way.

On Fig-15 of the attached drawings show a second variant implementation of the power conversion system, generally designated by the number 110, is also adapted to convert the energy of tides into electricity. In this second embodiment, similar components have the same numerical designation and, unless otherwise specified, perform the same functions. In the same way as in the first embodiment, the system 110 includes a partition wall 112, which is suspended during operation below and across the mass of water 118 moving in the channel 116 or equivalent.

On figa system 110 is shown with the tidal flow moving in the first direction indicated by arrow A, while in Fig, 11B system 110 is shown with a burst of the first stream, moving in the opposite direction. Top rope 124 and the bottom rope 126 (figure 11 not visible) partition 112 is made in the form of a closed loop, and on both sides of the partition walls 112 are located the ends 70 of the loop in which the direction of the cables 124, 126 essentially changed by 180°, as will be described in detail hereinafter. Between the upper and lower cables 124 and 126 and along them fixed several grids 119 sails (figure 11 are not shown), which, as will be shown in detail below, are adapted to move the cables 124, 126 across the channel to generate electricity. The system 110, as will be shown hereinafter, is arranged so that the upper and lower cables 124, 126 are moved only in one direction formed on the closed path, regardless of the direction of tidal flow.

In the following to illustrate the preferred embodiment, the ends 70 are located on land, although it should be understood that the ends 70 can be made in mass of water 118, although this will reduce the working length of the septum 112 and difficulties in hosting system 110. Thus, it is desirable that the ends 70 were placed on land, but it was filled with water Bay, running into the shore on each side of the channel 116 communicating with the masses of water 118. If that is th configuration eliminates the need to lift the upper and lower ropes 124, 126 from the water 118 to transition from a mass of water 118 to the shore on each side. The system 110 is not required to produce lift each of the gratings 119 sails and supporting cables 124, 126 of water 118 for the passage of each end portion 70. In addition, because the top rope 124 and the bottom rope 126 are in the water, decreases the current weight of the partitions 112, and the strength of the cables 124, 126 can be selected, respectively, with lower strength requirements that, in turn, reduces the weight of the cables 124, 126. In the preferred embodiment, each end section 70 has a diameter or width in the range from 500 to 1000 m, although this value can, of course, vary in accordance with the properties of specific water masses 118, across which has a partition wall 112.

As shown, in particular, on Fig and 12, the partition wall 112 contains at least one, and in the preferred embodiment, several grids 119 sails (not shown figure 11), with each grating 119 contains several sails 120, which, as in the previously described embodiment, is made of any suitable mode, such as a material based on aramid fibers, polymer, carbon fiber, or nylon. Each sail 120 is fixed inside the essentially rigid frame 122, and the whole grid 119 pivotally mounted between the upper rope 124 and lower the rope is m 126, as will be described in more detail below. In a preferred embodiment, the partition wall 112 contains a large number of gratings 119 sails installed one behind the other along the septum 112 between the top rope 124 and bottom rope 126.

At the shown embodiment, the gratings 119 is set at five sails 120, although they may be more or less, which is stationary and essentially parallel to each other by means of essentially rigid cross member 60. To secure the sails 120 in the position shown can be used any other means. The cross member 60 is attached to each of the frames 122 by any suitable means such as welding. Grille 119 sails also includes a shaft 62, which is pivoted between the upper rope 124 and bottom rope 126, and is also rigidly attached to the main sail 120 through the corresponding frame 122. Although the shaft 62 is shown passing through from the top rope 124 to the bottom rope 126, in the preferred embodiment, it is torn or missing in the area of the Central sails 120, so as not to interfere with the sail to swell in any direction. Thus, in practice, the shaft 62 is desirable to perform two pins (not shown), one of which is fixed between the top-most point of the Central frame 122 and the top rope 124, and the other listing the Jena between the lowest point of the Central frame 122 and the bottom rope 126.

Figure 10 shows that the shaft 62 pivotally attached to the top rope 124 through a suitable bearing 64, which is fixed on the top rope 124. The mount is the same design is used between the shaft 62 and the bottom rope 126. It is clear that this design allows the grill 119 sails to rotate around the axis defined by the shaft 62 so as to change the angle of attack relative to the tidal flow, as shown by the arrow And Fig.

Each lattice 119 sails further comprises directing means in the form of the blades 66, located under the top rope 124 and essentially above the sails 120. In the process, the blade 66 is located downstream relative to the array 119, although Pets and the arrangement of the blade 66 from the lattice 119 upstream. The blade 66 is attached to the shaft 62 by means of two brackets 68. The blade 66 may, of course, attached to the Central frame 122 or the cross member 60. In the preferred embodiment, however, the blade 66 is not located directly behind the sails 120 so that it was controlled by the main tidal flow, not flow between the sails 120. Although Fig and 12 bottom bracket 68 is shown attached to the shaft 62 to a point located below the upper point of the Central frame 122, in the preferred embodiment, within the square sails 120 shaft is missing, as was omanut above. Thus, in practice, the lower bracket 62 is slightly higher than shown, particularly at the point on the shaft 62 above the upper point of the Central frame 122.

Figure 9 schematically illustrates the grating 119, shown in Fig, you can see that the blade 66 is located in a vertical plane at a certain angle to the chord line of each of the sails 120, which are essentially parallel to each other. For the reasons discussed below, when the grating 119 sails set in the tidal flow, self-regulating blade 66 will be installed parallel to the direction of tidal flow A. the angle between the blade 66 and the sails 120 carefully selected so that when the blade 66 is mounted parallel to the tidal flow, the sails 120 are positioned at an optimum angle of attack relative to the tidal flow A. the Optimal angle of attack, in the present invention, is the angle at which the sail 120 generate maximum force in the direction of the arrow C. Such installation is possible as a result as a static mass balance of each grid 119 relative to the shaft 62 and installation center application of pressure per grid 119 about the shaft 62. The presence of static mass balance means that the weight lattice 119 distributed about the axis 62 so that the lattice 119 offset from siteline this axis. In other words, the center of gravity of the lattice 119 is located essentially on the axis 62 or close enough to it to achieve the desired result, as described below.

The position of the center of pressure of the lattice 119 for a particular angle of attack, in this case, the optimal angle of attack can be controlled by changing the tension or the curvature of each of the sails 120. While the sails 120, stretched tidal flow, as shown in Fig.9, must have the aerodynamic profile of the surface for which the position of the center of pressure of the entire lattice 119 coincides with the shaft 62. In the present embodiment of the invention, this is achieved by the combination of the center of pressure of the Central sails 120 with the shaft 62 and the use of the same number of sails 120 on each side of the Central sails 120 or shaft 62.

If you have a static mass balance grating 119 on the shaft 62, in the process using a relatively small force to rotate the grating 119 on the shaft 62. Thus, if the blade 66 is not parallel to the direction of tidal flow And a relatively small force applied to the blades 66, tidal flow turns grille 119 to until the blade 66 will not be parallel to the direction of tidal flow A. In this orientation, the sails 120 are at an optimum angle of attack relative to the tidal flow A. Described the design allows a relatively small blade 66 to hold the sails in this position, despite the presence of much greater force, created under the influence of the tide on the sails 120.

Figure 11 shows that in the process the upper and lower cables 124 and 126 are slightly bent in the direction of the tidal flow And that leads to a change in the angle of attack of the sails 120 (not shown in figure 11) in lattices 119 (not shown figure 11)placed across the channel 116. However, the use of self-adjusting blades 66 ensures that regardless of the location of any of the gratings 119 sails, each sail 120 will be positioned at the optimal angle of attack relative to the direction of tidal flow A.

As shown in 11 and 12, the system 110 includes a Converter 114, containing directing means in the form of a group of guide rollers 72, which are mounted in pairs on the respective shaft 74 and spaced relative to each other, with the upper and lower cables 124 and 126 pass through the respective guide rollers 72 and routed them. It is seen that the ends 70 on both sides of the partition 112 is essentially determined by the group of guide rollers 72, and each end block 70 shows a variant implementation uses four pairs of guide rollers 72, which provides a return path for the upper and lower cables 124, 126.

At least one, and in the preferred options the ante each shaft 74 rotates the gear 96, which may be directly attached to the shaft 74, as shown, or connected in any other way. Thus, when moving each lattice 119 sails across the channel 116, the upper and lower cables 124, 126 will be, due to the coupling with the guide roller 72, to rotate the guide rollers 72 and thereby rotate the shaft 74, which, in turn, rotates the gear 96, from which the PTO can be done in the usual way. Must be taken from slipping between the ropes 124, 126 and the respective guide roller 72. For example, each guide roller 72 may be made circular wedge-shaped groove, or the surface may be made rough or specially processed.

As mentioned earlier, the design of the system 110 provides movement of the partitions 112, more specifically the upper and lower cables 124, 126, in the same direction all the time, regardless of the direction of tidal flow. It should be borne in mind that when each lattice 119 sails reaches one of the end sections 70 and passes around it to come out on the other side end portion 70, moving in the opposite direction, the grating 119 sails will have the opposite orientation, with the guide vane 66 in front of the sails 120 relative to the direction ol the cast thread and not behind them as required. However, the guide blades 66 is used for each lattice 119 sails worked like a weather vane, and the tidal flow of water acted as a wind vane, gradually turning the bars 119 sails 180° around the axis 62 in order to accurately oriented in the direction of tidal flow. This is possible due to the static mass balance grating 119 relative to the shaft 62, and the combination of the center of pressure of the lattice 119 with the shaft 62. This relatively weak tidal flow acting on the blade 66, it is enough to rotate the corresponding lattice 119 on the shaft 62 by approximately 180°, until the blade 66 again will not take place behind the sails 120 relative to the direction of tidal flow.

However, the output from the corresponding end portion 70, each lattice 119 must now cross the channel 116 in the opposite direction compared to gratings 119 parallel side walls 112, lying upstream, and therefore, each individual sail must stand under its optimum angle of attack. As a result, lattice 119 on the downstream side of the partition must be the angle of attack, which is essentially the mirror image of the angle gratings 119 on the side walls 112, lying upstream. Therefore, you should have the in mind, what the guide blades 66 will first take a wrong angular position relative to the lines of the chord of the sail 120, and if it will remain in this position, the sails 120 will be oriented at an angle of attack relative to the direction of tidal flow, which does not ensure efficient operation. Therefore, the blade 66 has the ability to move between the first position and the second position, as shown respectively Fig and 14. In the first state, setting the blades 66 provides movement of the grating 119 in the same direction across the channel 116, while the second set of blades 66 causes the movement of the grating 119 across the channel 116 in the opposite direction. To facilitate movement between first and second positions, the blade 66 is installed on the hinge between the brackets 68 on the pivot axis 80, which is located near the front edge 82 of the blade 66.

In a preferred embodiment, the blade 66 is automatically switched when necessary, between the first and second positions, for example, when the grating 119 passes around one of the end sections 70 and is rotated 180° on the shaft 62 in order again to be correctly oriented in the direction of tidal flow. As shown in Fig-15, the system 110 for this include switching means functionally associated with each re is ekoi 119, moreover, these switching means are adapted for proper orientation of the guide vanes 66 in either the first or second position when changing to reverse the orientation of the grating 119 sails. In the shown embodiment, switching means overlook providermessage lever 84 protruding from the front edge 82 of the blade 66, and the corresponding emphasis 86, passing down from the bottom side of the top rope 124 at the location of the corresponding lattice 119 sails, and the stop 86 is located on both sides of the shaft 62. Means the switch is not shown on any of the other drawings, in addition to drawings presented on Fig-15.

As shown in Fig, grille 119 is rotated on the shaft 62 from the position in which the blade 66 is in front of the sails 120, the position where the blade 66 is located behind the sails 120. When the blade 66 is rotated approximately 90°, passing directly under the top rope 124. In the process of turning, the lever 84 touches the stop 86, in particular, its rounded tip 88, as shown in Fig. As the grating 119 continues to rotate on the shaft 62, the stop 86 will begin to interfere with the movement of the lever 84. This will cause the blade 66 is moved from the first position shown in Fig, in the second position shown in Fig, with the passage of the blades 66 under ve who hnim rope 124. From this position, further rotation of the grating 119 and consequently further withdrawal of the blade 66 from under the top rope 124, due to its flexibility, the lever 84 may deform sufficiently to pass over the tip 88 of the stop 86, as shown in Fig. The roundness of the tip 88 facilitates the passage of the lever 84 at the tip 88. From the positions shown in Fig, grille 119 continues to rotate, as described above, up until the blade 66, now switch to the second position, will not stand parallel to the direction of tidal flow. While the sails 120 will be oriented at an optimum angle of attack to generate maximum force in the direction of arrow C. Thus, in the process, when the grating 119 bypasses one of the end sections 70 and begins to move back across the channel in the opposite direction, the blade 66 per grid 119 provides automatic orientation of the grating so that the sails 120 were at an optimum angle of attack to the tidal stream.

In addition, when the direction of tidal flow reverses, as shown, for example, on figa and 11B, each of the gratings 119 sail, similar to a weather vane, will be forced to slowly rotate under the action of the thread on the shaft 62, through the use of the blades 66. When each R is setok 119 turned by 180° towards the approaching tide, with the blade 66, rotating after the sails 120, the blade 66 is again incorrectly oriented. However, as described above, the means 84, 86 of the switch will correct the orientation of the guide vanes 66, when it will take place under the top rope 124 during rotation of the grating 119 on the shaft 62.

Given the fact that the system 110, in particular the lattice 119 sails, used under water, it is desirable that means 84, 86 have a simple and robust design, although it should be clear that the lever 84 and the stop 86 can be replaced by any other functional equivalent. For example, between the shaft 62 and the blade 66 can be installed any lever mechanism (not shown)adapted to move the blades 66 between the first and second positions in response to rotation of the shaft 66. Can also be used any other design.

It is clear that, if necessary, can be used more than one blade 66, and the arrangement of the blade 66 can be changed to optimize its operation. For example, the blade 66 may be installed below the sails 120 so that the blade 66, as before, was ruled by the influence of the main tidal stream, not the stream flowing between the sails 120.

It is desirable that, while in the first and second positions, the blade 66 has experienced resistance to change his position in order to support the ü the correct orientation of the blades 66, when the corresponding lattice 119 passes across the channel 116. This resistance must be sufficient to hold the position of the blade 66 in a linear movement of the grating 119 across the channel 116, but can be overcome when the lever 84 with the effort passes by the stop 84 during rotation of the grating 119. This can be achieved in any suitable design, for example, using conventional ball retainers (not shown)installed on the brackets 68, with corresponding recesses (not shown)made in the upper and lower edges of the blades 66. Can also be used, and any other functionally equivalent structure.
