The invention relates to hydropower, in particular to power plants that use the energy of the waves.Known wave power plant, the so-called "Salter duck", which is a swing on the wave of the ship, sending the swing of his corps to the shaft associated with the energy Converter (see the book D. Ross wave power, M. , 1981 , S. 78-90).Known wave priamary compression with suction valves, partially filled with the working fluid and interconnected water conduit, and an air manifold with turbo-generator connected to the camera via an air piping-check valves.The disadvantage of this design is the complexity of its separation of the functions of the raft and tube compression, as well as the insufficient rigidity of the structural scheme of the mounting and movement of floats raft.The purpose of the present invention is to simplify the design and improve reliability.Achieved this goal because in wave electro pneumatic installation containing a floating body made in the form of two cylindrical floats, cameras compression with suction valves, partially filled with the working fluid and connected between a water pipe and an air manifold with turbo-generator connected to the camera via an air piping-check valves, compression chamber is made into a cylindrical floats, check valves are installed on the ends of the pipes from the air manifold, and turbine generator set at last.Water pipeline connecting the compression chamber can be performed by ticom hinge, thus, to tune to a wavelength change of the distance between the floats. For this purpose, set the tie winch turbine in this embodiment, the installation has two operating wheels opposite the rotation.Alternatively, wave electro pneumatic installation can be performed with the air manifold, directly connected to the cameras, and the turbine is made in the form of a turbine unilateral action.In Fig. 1 shows the proposed installation, General view; Fig. 2 - installation in plan; Fig. 3 and 4 - installation in operating cycles; Fig. 5 and 6 installation option with telescopic connecting the floats pipeline and dual air turbine; Fig. 7 and 8 installation option intended only to generate electricity.Wave setup consists of a housing made in the form of 2 cylindrical floats 1 and 2, filled with the working fluid 3 and having a compression chamber 4 and 5 with the suction valves 6 and 7, the air manifold 8. The floats 1 and 2 are connected a water pipe 9 for flow of water and air manifold air pipes 10 and 11, having at the ends of the side air manifold check valves 12 and 13. Thus, the design of elementary design. On the air manifold 8 installed turbine generator, consisting of an air turbine 14 and the generator 15.Installation is attached to the bottom using the anchor device 16 and rotates under the influence of waves on the hinges 17.Between the cylindrical floats 1 and 2 can be changed distance, which allows to adapt the installation to the variable wavelength. This is achieved, as shown in Fig. 5 and 6, the implementation of the water pipe 9 with telescopic inner toroidal tube 18 and the outer sealing element 19 in place of the coupling, and coupling the winch 20.The pipes 10 and 11 is connected to the air manifold 8 by means of hinges 21 and the turbine generator has 2 working wheels opposite rotation, on a "tandem". This arrangement improves the dynamic balancing of the installation and reduces the size of the generator 15.Alternatively, the installation can be performed only for electricity generation. In this case, there is no valve inlet-air vent. The air or other gas that fills the compression chamber 4, and 5 are moved from chamber to chamber through the pipe is achieved 10-11, which is installed inside the turbine generator. The hinges 17 in this embodiment, set at otdyha.The orientation of the wave front of installations with flexible mount to the bottom of the sea can be made by adjusting the lengths of 4 flexible fasteners 16 automatically or manually.The plant is operated as follows.Installation is transported into the sea and agoritsa to the ground by means of flexible fasteners 16 on the front probable waves. When you approach the crest of a wave building installation under its influence is rotated on the hinges 17 and the working fluid 3 starts from the chamber 4 of the cylindrical float 1 to flow into the chamber 5 of the float 2, jamming in the chamber air pressure H. The intake valve 6 of the chamber 4 at this time, opens under the action of the vacuum and allows air into the chamber. The valve 13 of the chamber 5 under the action of compressed air opens and admits compressed air to the air manifold 8. The compressed air from the air manifold through the turbine 14 is vented to the atmosphere. With the passage of the trough is a similar operation, but in this case, the chamber 4 becomes a compression chamber, and the camera 5 camera suction air. The air manifold 8 provides the leveling pressure before turbine generator when changing cycles of the cameras 4 and 5.The design of the proposed usally installation must lie on the ground" by flooding the floats 1 and 2 water through the valve with remote actuator (not shown).Wave setup (except option under item (3 formulas) can be assembled in the United garlands with simple mechanical Association with the merger produced by compressed air piping for use of a single wind turbine and generator or to supply compressed air to the shore for use in energy or refrigeration.The effectiveness of the proposed wave electro pneumatic installation is the lack of intermediate shafts, pistons, etc. in the energy conversion system, which greatly simplifies installation and increases the reliability of its work.
