The free end of each lever, i.e. the pump is pivotally attached to the float 5 of circular cross section, which in the upper half of the lateral surface fixed Anoprienko plate 6 at an angle to the direction of movement of the waves and 7 horizontal and 9 vertical stabilizers. 2 Il. The invention relates to gidroenergeticheskiy mechanical engineering and can be used in hydropower for converting the energy of sea and ocean waves into electricity.As an analogue of the selected pump installation (ed. mon. USSR N 1453077, MKI F 03 B 13/12, 1989) containing fixed on the bottom of the coast stationary support with a hinge mounted on it duplechin lever, where on one end there is a working chamber of variable currency is AVOK. Disadvantages installation are the negative effects of energy passing waves on the upper side of the float, which reduces the amount of torque on the shaft of the pump, the absence of the possibility of its use in any point of the basin and passing waves from any direction, the complexity and inconvenience of its installation, maintenance and repair. Noted deficiencies reduce the reliability and lifetime of the installation, as well as the efficiency of its use.Known floating water engine (patent USSR N 5018, CL 88B, 3, 1928), driven by waves containing a composite variable-length Duplessy lever and attached pivotally to the onshore support, where on one end there is a sector with a slanted movable rails and ratchet wheel on the shaft. The disadvantage of the engine is the lack of possibilities for use anywhere in the basin, the presence of a compound lever variable length sector, slanted movable rails and ratchet wheel, which reduces the reliability, service life and the efficiency of its use.Also known floating water engine (patent USSR N 910, CL F 03 B 17/06, 88B, 3-4, 1926), containing a raft and secured on the hinge h is sposobleny their turn, transition mnogoplatnye shaft and piston pumps, the piston rods of which are connected via a shaft rods with the upper ends duplechin levers. The disadvantage of the engine is insufficient reliability and low resource of its work, the presence of idle pairs duplechin levers in the reverse of their movement, a considerable number of parts, components, elements of communication and the complexity of its design, which reduces the efficiency of its use.As the closest analogue (prototype) adopted floating wave power plant (patent UK N 1542251, M CL5G 03 13/12, 1979), containing floating support with its positive buoyancy, to two of its opposite longitudinal sides of the fixed hinge single-branch levers rigidly secured to their free ends floats to the top of the fixed piston pumps, and the issues connected with the consumer. Lack of power is the presence of floats hemispherical profile with a flat top side, securing the pump to the upper part of the floating support, the lack of stabilization relative to the point of its attachment to the anchor, the lack of braking devices limits the stroke of the levers exceeding raschityvat its use.The main objective of the invention is to increase the service life, reliability and stability of power and efficiency, which is achieved as follows.The proposed floating hydroelectric containing anchored floating support with pumps connected to the turbine unit and the levers, one end of which is fixed floats, and the other pivotally connected to the support and connected with the working body of the corresponding pump, characterized in that the floats at the end of each arm is fixed and hinged to each of them is equipped with Anoprienko plate, horizontal stabilizer and focus, and each lever is equipped with Anoprienko plate and a stop mounted on the lever with the opportunity to interact with the response, focusing on the float, this Anoprienko plate float secured to the latter in the upper part at an acute angle to the direction of movement of the waves, the horizontal stabilizer is fixed on the opposite side of the upper part of the float, and its plates are located above the float parallel to the direction of movement of the waves, and the vertical stabilizer is fixed at the bottom of the float, while Anoprienko plate, Richa above the float.The rotary float round cross-section is rigidly secured thereto Anoprienko plate at an acute angle, vertical and horizontal stabilizers its position at an acute angle to the direction of movement of the waves and Anoprienko plate under the same angle on the end of the lever and above the float is allowed to increase when turning the levers of bottom-up energy efficiency passing waves of any parameters, to improve the smoothness of rotation of the levers and the uniformity of the torque on the shaft of the pump and increase upornosti and sustainability of water supply to the turbine of the hydraulic unit. The presence Anoprienko plate on the end of the levers allowed to increase the lifting force of the float in the lower position of the levers to increase the torque on the shaft of the pump, and in the top rated position be used as the most simple device limits the stroke of the levers. The availability of floating support stations with negative buoyancy made it possible to fix it pumps below the surface of the water and to eliminate air leaks and improve the reliability of their work, and also to reduce the negative impact of passing waves on the design of the station and improve the reliability of its work. The presence of the suction turbine unit of water in the points with the lowest height of the passing waves, as well as to improve the uniformity of rotation.Given the above and the comparative analysis of the proposed technical solution the technical solution of the closest analogue (prototype) and other analogues in the field of hydropower has led to the conclusion that this hydroelectric power plant has significant differences from the known power plants, its distinctive features are essential, and the conditions of the task proposed by the invention fully resolved.In Fig.1 gives a General view of the hydroelectric power plant of Fig.2 node a (the location of the pivoting float and Anoprienko plate on the end of the lever in the extreme positions of its stroke).The proposed wave floating hydroelectric containing anchored floating support 1 with part-turn actuator pumps double acting 2 connected to the turbine of the hydraulic unit 3 and the arms 4, one ends of which are attached the floats 5 and the other pivotally connected with the support 1 and connected with the working body of the corresponding pump 2. The floats 5 at the end of each arm 4 is fixed hinge, and each of them is equipped with Anoprienko plate 6, the horizontal stabilizer 7 with two parallel Postscriptum on the lever 4 with the ability to interact with a return stop 10 on the float 5. Anoprienko plate 6 of the float 5 is fixed on the latter in its upper part at an acute angle to the direction of movement of the waves, the horizontal stabilizer 7 is fixed on the opposite side of the upper part of the float 5 and the plate 8 are located above the float 5 parallel to the direction of wave movement. The vertical stabilizer 9 is fixed at the bottom of the float 5. Anoprienko plate 11 of the lever 4 mounted on its end at an acute angle to the direction of wave movement in its lower position and located above the float 5.The operation of hydroelectric power plants is as follows.Passing through hydroelectric waves affect the floats 5 and Anoprienko plates 6, 8, 11 of the levers 4, turning them up to the calculated position. This Anoprienko plate 6 is kept constantly under the same acute angle to the direction of movement of the passing waves with horizontal stabilizer 7 and plate 8, and the vertical stabilizer 1. At the top of the estimated position of each lever 4 Anoprienko plate 11 occupies a position parallel to the direction of wave movement and operates as a braking device, which does not allow further progress P0 floats 5, holding plate 8 of the stabilizer 7 from rotating them clockwise, thus increasing the braking force to addition to the plate 11. Further rotation of the levers 4 above the calculated position is eliminated exposure energy passing waves at the plane of the plates 8 and 11, when they will begin to take a position with a reverse angle to their direction. With further movement and reduce the passing wave levers 4 rotated under its own weight down to the starting position. In the absence of waves stabilizer 9 float 5 is held in working position Anoprienko plate 6 and plate 8 of the stabilizer 7. The incident the next wave again affects Anoprienko elements 5, 6, 8 and 11 of the levers 4, turning them up. The cycle repeats. The resulting reciprocating rotary movement of the levers 4 provides part-turn actuator pump double action 2, a continuous and uniform supply of water to the consumer-unit 3, which ensures the normal operation.
