The invention relates to a wave hydropower, in particular for wave energy installations.

Known wave power installation comprising two side pontoons with rods connected with them in the middle part of the vertical pipe and mounted inside the tube generator with a conversion mechanism, which is to increase the capacity and efficiency has two additional pontoons associated with side pontoons by means of tie-rods, and pipes connected with the rods of the side pontoons hinge.

The disadvantages of the known device: having multiple degrees of freedom at Isley and therefore incomplete filling the internal cavity with water, that, in turn, reduces the capacity and efficiency of the installation; secondly, under the influence of tidal or storm nature of the waves is constant and uncontrolled drift of the known installation, without excluding possible mooring her to the shore; the absence in the upper part of the vertical pipe of the air vents, which prevents possible full the water filling the internal cavity of the installation and leads to a certain loss of power and reduced efficiency.

Closer to the technical essence to the present invention is a receiving chamber of the wave setup containing voenoplennih socket, partially submerged under the water level, set on stilts with the possibility of vertical movement and having a branch pipe of the exhaust air, in order to increase the utilization of energy waves socket provided at the rear end of the bore to release waves and partially submerged vertical plate placed at the entrance of the socket with a uniform pitch along its longitudinal axis, and plot the socket at the rear end is submerged under the water level and the outlet air outlet located in front of the said plot.

The disadvantages of the known devices are: in ratoi part of the wave energy on such movement, that reduces the utilization of wave energy; potential distortions Anoprienko socket on piles due to uneven process of rolling forward and rolling back the waves, resulting in reduced reliability of operation of the known devices and processes of discharge and supply of air through the pipe to the consumer; the discharge through the pipe is not air, but water-air mixture, as the real waveform differs sharply from the correct sinusoidal profile, as well as the outline of the profile of the wave inside the socket.

Known and other power plant running by converting wave energy into energy of compressed air, but uses wave energy inefficient.

The purpose of the invention more efficient use of wave energy and increase the efficiency of the installation.

This goal is achieved by the fact that the wave energy facility containing Anoprienko zone and partially submerged in water, the lower part, mounted on legs, working her body made in the form of two oppositely installed swivel panels, the rear end of the top panel is equipped with a cargo, and the rear end of the bottom panels of them is prasouda between a reception area.

This embodiment of the wave power plant allows comparison with the prototype to ensure that the direct impact of waves on the working body of the cloth as a single link that converts wave energy and creates a torque on the shafts PTO.

In Fig.1 shows a wave power plant, a plan, and Fig.2 section a-a in Fig.1, the passage of the wave crest between the front ends of the working panels of Fig.3 is the same, the passage of the wave crest between the rear ends of the working panels.

Wave power plant comprises a cargo 1, mounted on the rear top of the working panel 2, and 3 floats, mounted on the rear end of the lower operating panel 4; panels 2 and 4 are involved by means of brackets 5 and 6 with the shafts 7 and 8 PTO, mounted to rotate on the bearings 9. The front ends of the panels 2 and 4 are provided with radial guide elements 10 and 11 are oriented in opposite directions relative to each other. Working panels 2 and 4 with load 1 and 3 floats balanced in such a way that the guide elements 10 and 11 are in their initial position on the possible Maksimovka works as follows.

The bulk of the water rolling waves sent by the elements 10 and 11 and rushes to the area 12 between the panels 2 and 4 (Fig.2), passes the Central part of the installation, the crest of a wave affects the upper panel 2, lifting up his rear end with load 1, and the weight of the mass of water moves the rear end of the panel 4 with 3 floats down (Fig.3), providing further unchecked waves. If you roll back a wave, immediately after the passage of the current sliding water, the float 3 float up, pulling the rear end of the operating panel 4, and the load 1 is moved down, Potapova the rear end of the operating panel 2, thereby resulting in a starting position of the panels 2 and 4 (Fig.2) and providing the subsequent capture of the next rolling wave. Working panels 2 and 4 by means of goods 1 and 3 floats balanced in such a way that in the initial position the rear ends of the panels 2 and 4 are very close to each other (3 floats in suspension, cargo 1 down), and the front ends of the panels 2 and 4 are maximally separated from each other with the formation between the guide elements 10 and 11 Anoprienko zone 12.

Wave power installation works created in the course of its movement torque on the shafts PTO.

The economic efficiency of wave power plant due to possible full the simplification of the structure of its creation of conditions for practically free input and output waves with simultaneous conversion of dynamic pressure them into rotational movement of shaft PTO.
