The invention relates to hydropower, hydroelectric power plants, using energy waves that occur on the surface of the seas, oceans and other large reservoirs of natural or artificial origin.Known wave hydro power plants, in which the energy Converter wave ausesaurine, skipping rope, attached to the lower end to the anchor, and the upper end through the guide block and the lever to the spring tension, which is attached to the bottom of the float. Vertical movement of the float on the excitement happens tension and compression springs, causing the swing arm, which by the connecting rod causes the rotation of the flywheel, which is connected with a flexible coupling to a generator located as all these parts of the float (the patent of the USSR N 8715, CL F 03 B 13/18, 1927).The wave power hydropower is limited by the maximum power of the generator. Low reliability due to the presence of only one generator, as well as intensive abrasive wear of the rope in the area of contact with the tubular part.These drawbacks are partially eliminated in the wave energy installation comprising a buoyant elongated with mechanical stabilizers and posted two electric actuators, including power horizontal shafts with star wheels, gears, flywheels and pulleys and flexible covering the last link, the ends of which are fixed anchor and the weight, and pulley drives are located on the sides of the pontoon, and a flexible connection prochnau of the boat set sail in the form of shutters with adjustable blades and the mechanism of rotation of the plates. Generators, actuators and sail are located on the surface of the pontoon (ed. St. USSR N 1460394, CL F 03 B 13/12, 1987).With side rolling of the pontoon on the excitement of a flexible connection with the goods, covering pulleys drives, due to the frictional forces causes the rotation of the generators. The wave power hydropower is limited to a total maximum capacity of the two generators. Lack of reliability due to the presence of only two generators.The aim of the invention is to increase capacity and improve reliability in the operation of the wave power station site.This goal is achieved by the fact that well-known wave hydroelectric containing the pontoon and the energy Converter wave, made in the form of two generators driven pulleys and covering them consistently anchored one end of a flexible connection with the tension device, provided with at least two additional wave energy Converter and fixed on the bottom of the supports, while the generators converters at least two attached to the supports below the water level, the tension device is made in the form of springs and winches, springs included in cardoen with the upper ends of the flexible links.Pinning at the bottom of the at least three bearings allows to increase the power of the wave hydroelectric power.Fixed on each support at least two generator makes it possible to increase the reliability of the wave hydro power plants and to increase its capacity.The inclusion of springs in each flexible connection between the armature and generators converts reciprocating movement of the flexible links in the rotational movement of the rotors of the generators.Fastening at least three flexible links with anchors to the pontoon with installed and evenly spaced around the perimeter of the winch allows you to stabilize the load wave hydro changing the force of the waves.This embodiment of the wave hydro enables you to apply as pontoon case of any decommissioned ship and use it to its carrying power, irrespective of the value.In Fig. 1 shows a General view of the wave of hydroelectric power in the initial position, in plan; Fig.2 - section a-a in Fig.1; Fig.3 - view of B in Fig.2.Wave hydroelectric contains the pontoon 1 and Preobrazhenie pulleys 7 and the support 8.The pontoon is made in the form of a floating platform arbitrary, such as round shape in plan. On the pontoon evenly along the perimeter of the installed winch 4 to which the upper end is attached a flexible connection 2. Winches are used for preliminary partial stretching of the springs before turning hydropower operation and regulation of the length of flexible connections when changing forces of unrest that allows you to stabilize the load wave hydroelectric power.Flexible connection 2, is attached to the bottom of the sea anchors 3, are used to hold the pontoon in the horizontal and vertical planes and create a torque on the drive pulley 7 while moving the pontoon 1 on the excitement. Each anchored flexible connection comprises sequentially pulleys at least two generators.The springs 5 are for reciprocating movement of the parts of the flexible links 2 concluded between the pontoons and anchors 3 under forced vibration of the pontoon 1.Generators 6 are used for electricity generation by the synchronous operation to the shared network wave hydro and fasten at least two for each support 8 to each other and one above the other is their several coils of flexible links 2 in a rotational movement and transfer it to the shafts of the generators 6, at the free end of which a pulley fixedly mounted. The transformation of one form of motion into another occurs due to the friction forces arising between the coils of flexible connections 2 and the working surface of the pulley 7 while moving the pontoon.The supports 8 are used for fixed installation on the bottom of the at least two generators 6 driven pulley 7 is driven in rotation covering them sequentially one flexible connection so that they are always above the springs 5.Hydroelectric power plant operates as follows.In the initial position (calm sea) pontoon 1, floating on the water surface, is fixed in the horizontal and vertical planes by flexible connections with 2 anchors 3 and the spring 5. Flexible connections covering several coils driven them pulleys 7, using winches 4 are taut with the effort of ensuring the presence of the springs 5 polarstate.With the approach of the wave pontoon 1 due to its lifting force begins to rise on its crest and creates additional efforts tension in the flexible elements 2, the lower ends of which to anchor 3 is attached to the spring and can be moved by stretching the cut pulleys 7 are connected with flexible connections, and to increase the potential energy of the spring 5 by further stretching. Under the influence of these additional efforts, the lower ends of the flexible connections 2 begin to move to its extreme upper position, the rotating shafts of the generators in a clockwise direction and stretching the spring (stroke).In fact described stroke of the flexible connection begins when the pontoon is located at the foot of the wave (in a trough between waves) and begins to rise to its crest. At this point, the lower ends of the flexible connections 2 occupy the lowest position, and the spring 5 is compressed. After passing wave crest pontoon 1 starts to fall for her sole and flexible connectors under the action of a fully stretched springs there are additional efforts compression using friction forces are transferred to the working surface of the drive pulley 7 and create a torque directed in the opposite direction. The springs are compressed, the lower ends of the flexible links 2 are moved to the lowest position, and the shafts of the generators 6 starts to rotate counter-clockwise (reverse), converting the potential energy of the springs 5. While the linear displacement of any point on the flexible connections is equal to the difference between the length of the springs in poolname begins to rise on its crest before reaching the starting position, stretching of the spring 5, moving up the lower ends of the flexible connections and the rotating shafts of the generators clockwise.The following cycle is repeated continuously.With increasing power disturbances (wave heights) above rated flexible connection 2 begin to get out from the reel winch 4, while additional efforts stretch in them at work during their lower ends will not decrease. In the process of returning power disturbances to normal is the winding of flexible connections to the drums of the winches, their length decreases, and the extra effort of stretch in them when working stroke increase. In both cases, the power remains constant regardless of the degree of excess of the actual forces excitement over the calculated and the speed of its change.Pinning at the bottom of the at least three bearings allows to increase the power of the wave hydroelectric power. Fixed on each support below the water level at least two generator makes it possible to increase the reliability of the wave hydro power plants and to increase its capacity. Fastening at least three flexible links with anchors to the pontoon with installed and evenly spaced around the perimeter of the winches popolnenie wave hydro enables you to apply as pontoon case of any decommissioned ship and use it to its lifting force regardless of the size. Wave hydroelectric containing the pontoon and the energy Converter wave, made in the form of two generators driven pulleys and covering them consistently anchored one end of a flexible connection with the tension device, characterized in that, to increase capacity and improve reliability in the operation of hydroelectric power, it is equipped with at least two additional wave energy Converter and fixed on the bottom of the supports, while the generators of transducers, at least two, attached to the supports below the water level, the tension device is made in the form of springs and winches, springs included in each flexible connection between the armature and generators, winches evenly spaced around the perimeter of the pontoon and are connected with the upper ends of the flexible links.
