The invention relates to low energy and can be widely applied where often on the coast of the waves arise and there is no centralized power. The unit can be easily mounted on the shore of a sea, lake, river, or any body of water.

Numerous wave power plant different designs, one such is given in the author's evidence 1377444. In Hey inserted. The float of the wave setup is deducted from drift waves special telescopic device.

Known other wave power plant, shown in the journal Ira 9, 1982, S. 31, article "the Path to salvation. This article provides one of the best in the world coastal wave station of the author Russell.

The famous coastal wave station is located in a recess coastal abutment, in this recess is mounted a turbine, which through the upper valve comes the wave and the effect on the turbine, and through the lower valve wave comes. Although this device was recognized as one of the best coastal wave energy, it is not devoid of disadvantages, the main of which are: the relative low efficiency, structural imperfection, limited in their capabilities.

Known power plant, described in the author's certificate of the USSR 1273635, CL F 03 B 13/00, 1986. This unit contains a float placed in the chamber of variable water level and a mechanism for converting reciprocating movement of the float in the rotation shaft of the electric generator, comprising a flexible connection with the system blocks.

This technical result is achieved by the fact that as a working organ is a structure consisting of a hollow float-cylinder placed inside a water lattice cylinder, mounted on a solid base stretching from coastal power of emphasis and located inside the conical sump having on their walls hinged polucheniya valves, contributing to the collection and recovery of water from the working body (float-cylinder), linked through cross with a generator of electric current.

The invention, its effect is primarily determined by the efficiency and significant simplification of the structure of the entire device and especially its working body, which is made by float-cylinder, placed in a water lattice cylinder, employee retention, guiding device, installed at coastal power lock, inside conical sump directing versatile waves on coastal power stop where they are, even when the wave rises to a high level, pulling the hollow float-cylinder kinematically linked through cross with a generator of electric current.

Improving the efficiency of coastal power plant 1 is provided with installation of water lattice cylinder 2 with a hollow float-cylinder 8 near coastal power lock 10, which are directed channel water

The device can be manufactured in any small workshop from widely available materials and products and installed underwater engineering team.

Technical and economic effect of the device is that due to the design of the tapered channel-header is not only able to pass any direction, but much to raise the water level even at a weak waves, providing high efficiency with a simple structure.
