This invention relates to uses for water plant placed under water and containing a blade or blades attached to a rotating closed loop, which runs between facing in opposite directions corresponding rotary disk and is provided in the circular motion of the blades under the influence of the water, and at least one generator designed to generate electricity and connected to the closed circuit. This invention also relates to a method of operation uses the flow of water to the plant.

Currently, there is increasing need for the use of "clean renewable energy". As one of the largest existing sources of renewable energy are considered powerful sea currents and water tides. There are many suggestions concerning how to use these sources, most of which refers to the use of water turbines in various configurations.

Also, there are concepts which are located under water blades to use water as an energy source, described, inter alia, in the patent of Norway No. 20035448.

In Japan patent No. 410061598 shows the closed system of the blades or vanes, put in motion in the Rog two rotary disks, in which operating parameters are adjusted by means of the elevation angle of the blades, speed, square blades, etc. U.S. Patent No. 6081043 also applies to a closed system of blades or vanes, which, however, is intended for use in a wind power plant and in which it is possible to control the orientation of the blades relative to the drive cables.

Can also be made by reference to U.S. patents No. 1847855 and 4350474 that relate to the tidal power plants to generate electricity.

The purpose of this invention is to provide uses for the water plant, which can be submerged in water at the desired depth and may undergo as lifting and stretching under the influence of flowing water with continuous electricity generation.

The above goal is achieved by using the flow of water to the plant described in the independent claim 1 of the claims, due to the installation of rotary disks in the respective frames, which can be securely attached, and closed the chain passes freely between the said frames and around the rotary disk, and also due to the fact that at least one of the rotary disks attached to a drive mechanism, coupled with a universal joint that is attached indicated the p generator.

Other embodiments of the uses for the water plant is characterized in dependent clauses 2-14 claims.

A loop may contain two closed rope, and these blades or vanes are located between the respective cables, each cable can be routed over the corresponding rotary disk and around it so that the blades or vanes are moved on a circular path between the respective pairs of the rotary disk.

Universal joint can adjust the speed of movement of the cables relative to each other thereby providing regulation of the angular position of the blades or vanes relative to the flow of water. Universal joint can also be connected with a drive mechanism attached to each rotary disk in the corresponding frame.

In addition, these frames are preferably firmly attached so that they can be rotated to regulate the angular position of the cables in such a way that the tension of the cables is directed perpendicular to the axis of rotation of the rotary disk.

The drive mechanism may include a first pulley attached to the axis of rotation in common with the rotary disc, which by means of a belt or chain attached to the second pulley attached to the shaft, a universal joint is. Alternatively, the drive mechanism can operate with the shaft.

A pair of rotary disks can be made with the possibility of their independent rotation relative to each other, and their regulation by means of universal joint.

In one embodiment, the universal joint may be a transmission containing at least two planetary gear, and the respective shafts, a universal joint attached to the shafts of the planet gears of the planetary gear, and between the ring wheel of the planetary gear are the first bevel gear, a shaft connected to the generator, and the second bevel gear, a shaft attached to the servo motor. A shaft connected to the generator, preferably with the ability to control the overall movement of the cables during operation of the generator and the shaft attached to the servo motor, preferably with the ability to control the differential movement of the cables, regardless of the General move to regulate thereby the angular position of the blades between the ropes.

Universal joint and the generator can be placed in a waterproof case.

In addition, the rotary disks can be made possible the awn mutual displacement along the specified axis of rotation providing thereby changing the distances between pairs of rotatable disks depending on the angular position of the blades.

In a preferred embodiment, the blade may be at least partially arcuate profile in the shape of an airplane wing, and specified the curved profile is used to ensure equilibrium of the blades in the water, and any deviations from the equilibrium position preventing forces acting on the blade.

These blades or vanes can be attached to the appropriate cable with clamp connection means, and the specified clamping means includes clamping mechanism and configured to provide limited movement of the blades when they pass over a rotating disk and holding the blades in the desired position otherwise. In addition, clamping the connecting means may be arranged to control the angular position of the blades in the water.

The rotary disks can be made with the possibility of displacement in the axial direction in the respective frames.

These goals are also achieved using the method described in the independent claim 18 claims, by fixing the rotary disk in the respective frames, which can be firmly secured, and allow passage of the closed circuit between the frame and around the rotary disk, and by attaching the universal is Amira between the drive mechanism and at least one of the rotary disks, moreover, the specified universal joint provides the management of the overall movement of the cables a closed circuit during operation of the generator and the differential regulation of the movement of cables, regardless of the General move to regulate the angular position of the blades between the ropes by regulating the speed of movement of the cables relative to each other.

In accordance with alternative options for implementing the said method between the universal joint and the rotating disks can be attached to the drive mechanism, which may lead closed chain movement on a circular path by creating breakout force and lifting efforts that are passed to the ropes, this blade can be tilted relative to the water flow.

Blades can be installed on the wires, such as wire, rope, steel wire rope, etc. and adjusted by obtaining the angle of inclination relative to the water flow, so that they have an impact on the ropes, which pass across the water flow. The force acting on the blades caused by the thrust (pushing force) and a lifting force, similar to the principle of operation of an airplane wing. It is also possible to convert a certain amount of kinetic energy of water into electrical energy. The total area of all lo is ATOC provides a relatively large area, which is valid for water. The specified device is particularly suitable for use in the Straits and fjords, perhaps, in those places where there is a natural narrowing of the relief, which provides a higher flow velocity of the water at high tide.

This facility can also be used in rivers.

This facility can be located at a depth at which it does not create obstacles for vehicles and people, for example at a depth of 20 m Installation can be easily increased in size and can be adapted to the conditions of a particular locality by changing:

- the size of the blades,

- number of blades/length tensile,

- tilt/angle of attack (can be changed during operation).

The first blade is firmly attached to the cables by means of two flexible segments and move with the cables around a rotating disk.

The relative displacement of the points of fastening of the blades on the ropes determines the inclination of the blades relative to the direction of flow.

By changing the distance between the rotary disks in combination with longitudinal displacement of the cables relative to each other, the angular position of the blades can be changed relative to the direction of flow. The blades also have a limited ability to rotate vertically. Water flow in a large extent affects the corners of the e position of the blades relative to the vertical.

Due to the profile of the blades has one angular position at which the equilibrium position. The blade preferably is self-stabilizing. Any deviation from this angular position oppose efforts that act on the blade. In the case of an application by the pushing force from the blades along the cables (the transfer of energy to the generator and cables across the profile of a closed circuit receives an arched shape.

In order that the cables did not come out of the grooves in the rotary disks, disks secured in a horizontally rotatable frame that adapts to the angular position of the cables. This means that the power cable tension is always directed perpendicular to the shaft.

Cables actuate the rotary disks, which in turn actuate the generator with the drive mechanism. The drive mechanism is made with the optimum number of revolutions of the generator depending on the speed of ropes.

As shown in the drawings, an embodiment of the proposed uses for the water plant 10 includes a loop 14, which contains at least two cable 20. Between these cables 20 with clamp connection means 22 has multiple vanes or blades 12, preferably so that the said blades or vanes attached at their middle part and are in the equilibrium state, but depending on circumstances, they can also be attached with displacement from their equilibrium state. The cable is 20 pass through the respective rotary disks 24, which preferably are arranged in pairs facing in opposite directions frames 16, 18, so that between the rotary disk 24 is formed a gap, through which can pass the blades or vanes 12 when the rotation of the disk 24.

The blades or vanes 12 are made so that the flow of water pushes the blade (thrust) while passing a stream of water with greater speed over the surface of the rear blade (boost). The resulting energy provides additional impact on the ropes and, consequently, an increased power output. Thus, the selected profile of the blades or vanes 12 may be similar to the curved profile of an airplane wing. Alternatively, the blades 12 may be flat on both sides and/or have a non-arcuate profile, however, this leads to less effective results.

These frames 16, 18 can be firmly attached to the bottom of the river and possibly other equipment in the water or in the sea, so that they do not interfere with navigation or people. Frames 16, 18 preferably are rotated in the horizontal direction and serve as a support for closed circuit 14, the drive mechanism 28 and the other equipment of the power plant 10. As shown in figure 3 and 4, the closed circuit 14 typically is exposed to the force of the water flow and BP is me work takes arcuate shape, which means that rotation of the frames to prevent the escape of cables grooves in the rotary disks 24.

The rotary disk 24, as described above, are arranged in pairs in each frame 16, 18 and preferably rotate on the same axis of rotation. A pair of rotary disk 24 is made to rotate independently of each other and their regulation by means of universal joint 50. The drive mechanism 28 attached to the same axis of rotation as the first pulley 32, which is attached to the second pulley located on the shaft 40 of the hinge 50. These first and second pulleys connected by a belt or chain 34 in a generally known manner so that rotation of the disk 24 and, therefore, the first pulley 32 causes the rotation of the second pulley 36, which in turn rotates the shaft 40 of the hinge 50. One or two such drive unit 28 can be located in each frame, however, preferred is the location of the two drive units 28 on the outer side of the rotary disk 24, so that they do not hinder the passage of the blades of the disks 24. The first pulley 32 may be mounted on the same axis of rotation as the rotary disk 24, and have the same direction of rotation. The drive mechanism 28, as an option, can operate with the shaft, not the belt or chain, as described above.

In addition, the rotary disk 24 is made is with the possibility of their displacement in the axial direction along the axis of rotation, so the distance between them may vary with the change of inclination of the blades 12.

Specified universal joint 50 is located at one or both frames 16, 18 and attached to the generator 60 to generate electricity. The hinge 50 and the generator 60 can be placed in a waterproof housing 26. Figure 5 and 6 shows one end of the power plant 10 in accordance with the frame 16 and the housing 26 without them. As can be seen from the drawings, the drive mechanism 28 is attached to the corresponding shaft 40 of the universal joint 50 to control the operation of the generator 60.

In an alternative embodiment (not shown) of the generator 60 can be located not in the water. In this case, the generator 60 can be appropriately attached to the hinge 50 by using rigid or non-rigid connection. One advantage of this solution is, first of all, simplify maintenance of the generator.

In addition to the control operation specified generator, universal joint 50 is made with the possibility of independent control of the speed of movement of each cable 20 in a closed circuit 14 for regulating the angular position of the blades 12 in the water. This regulation can be performed during operation of the power plant 10, for example, due to the implementation of this hinge 50 in the form of a gearbox with two planetary gears 42. Suppose Agueda, the design of the planetary gear known in the art, and therefore its detailed explanation is not given. The planetary gear is a variation of the transmission with the toothed wheel. It is made of a set of toothed wheels: the inner Central wheel, the subsequent planetary gear and the outer ring of a wheel with teeth. High quality ensures a long service life of the planetary transmission, and, in addition, it can transmit a large torque.

Torque applied to the shafts 40 of the universal joint drive mechanism 28, is transmitted to the planetary wheels 46 and, in turn, is distributed between the Central wheel 44 and the ring wheel 48. If the ring wheel 48 is stationary, then all motion is transmitted to the Central wheel 44. The two planetary gear 42 facing each other, so that the total movement of the cables 20 in the closed circuit 14 lead to the total angular displacement of these planetary transmission. On the ring wheels 48 are made inclined teeth facing each other and between which the first bevel gear 56 attached to the shaft 54 to the generator 60, and a second bevel gear 58 attached to the shaft 52 to the servo motor (not shown). The shaft 54 attached to GE is erator, ensures the management of the overall movement of the cables 20 during operation of the generator and the shaft 52 attached to the servo motor provides the differential regulation of the movement of the cables 20, regardless of the General move to regulate the angular position of the blade 12 between the cables 20.

Thus, in this setting there is the possibility of mechanical separation of the common and differential moments applied to the various shafts. Differential time, which provides the change in angular position of the blades 12, is transmitted to the servo motor, and the total displacement, which determine the energy at the facility, transferred to the generator 60.

The torque applied to the shafts 40 of the universal joint from the drive units 28 may, alternatively, be transmitted to the Central wheel 44, but it will lead to another gear.

When tilted vanes 12 are held by the rotary disk 24, the blade can be bent relative to the clamping of the connecting means 22. Thus, clamping the connecting means must be flexible. However, at large strains (under which we can expect the emergence of local turbulence) flexible latch may not be able to provide rigidity sufficient to prevent twisting and sastrawan the blades.

This problem can be solved, as illustrated in figures 9 and 10, by performing the clamping connection means, which enables limited movement. The specified clamping the connecting means must in this case to provide flexibility, high enough to pass around the turning disk, but at the same time sufficiently small to retain the blades within the permissible angular positions. In addition, clamping the connecting means 22 may include a spring-loaded mechanism (e.g., self-regulating). Examples of satisfactory characteristics commit such clamping the connecting means include: ensuring sufficient support for blades under large strains, sufficient flexibility to pass around the wheels, providing the possibility of changing the inclination of the blades, corrosion resistance/ability to not break down in seawater and enabling a shortening of the connection around the wheels.

An important function of clamping the connecting means when the commit is the possibility of blade passage around the rotary disk. As these two connecting means are located on the ropes not directly opposite each other, the latch may start to move around the rotary drive early the e other. This may lead to a slight twisting of the blades, so the connection must be flexible enough to make this move does not put undue tension. Another reason for providing a certain degree of rotation of the blades, it is advisable from a practical point of view, is a probable occurrence of uneven currents of water, which for a short time, will increase the force acting on the upper or lower side of the blade. In this case, the blade may be slightly rotated, but due to the shape of the blades of the balance of power is restored, so that the blade is returned to the neutral position. Even with a steady flow of water force acting on the upper part of the blade exceeds the force acting on its lower part, by tightening the blades, so that said upper part becomes more perpendicular. This blade can be rotated around its Central axis, in the case of too strong rotation occurs, the corresponding situation for the lower part of the scapula.

The principle of this construction is that when the rotation of the cylinder 70 inclined surface of the protrusion 76 slide on the inclined surfaces 78 in the crown element 72, which moves downward in the groove made in the building the e 80. In this place there is a spring 74 is pressed against the rear wall of the housing. During rotation of the cylinder 70 at a certain angle, for example 15°in one direction, the protrusions 76 are faced with a wall element 72 and then can no longer turn. If you continue to try to turn the cylinder 70, the force acting between the protrusions and the wall of the spreader element, will prevent this movement. Crown element 72 cannot rotate because it is located in the groove of the housing 80. When the action point of the force ceases, the spring 74, which has been compressed, is returned to the neutral position and then pushes the element 72 up. As a result of this inclined surface 78 of element 72 pushing the inclined surfaces of the protrusions 76 in the direction, with the cylinder 70 is rotated back to its original position.

In the lower part of the housing 80 has a connecting means 82 for attaching the cables 20 and the cylinder 70 has a place 84 for attaching the blades 12.

In addition, for a given power plant is also required adjustments to the mounting position. When the power cable pair 20 can take arcuate shape. This is largely corrected by the rotation of the support points, i.e. frames 16, 18, however, because the outer cable should be somewhat longer than the inner cable, can the t to be a situation where cables are not included perfectly into the groove on the rotary disk 24. It is assumed that this problem can be solved by moving the mounting position of the corresponding frame (e.g., its offset from the center). In practice, this can be done by pushing the rotary disk 24 in parallel along the shaft by hydraulic means.
