The present 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. 78-80).

The disadvantage is that the formers energy, in conditions, when this shaft is fixed garland "ducks" oscillating asynchronously.

Also known wave power installation comprising a floating partially filled with the working fluid body with a convex bottom surface separated by a hollow vertical partition into two communicated among themselves at the bottom of the compression chamber with the suction valve, and the air collector user connected to the compression chambers by means of check valves (see U.S. patent N 4364715, CL 417-100, 1982).

The disadvantage of this technical solution is some design complexity, namely, that two partitions are element capacity, creating buoyancy installation and connection of cameras compression is achieved through a flexible hose.

In addition, this design due to adverse hydraulic shape has a large energy loss.

The purpose of the invention is the increased efficiency and simplifying the design.

Achieved this goal that the proposed wave energy installation comprising a floating partially filled with the working fluid body with a convex bottom surface, RA is ture compression with suction valves, and the air manifold of the consumer connected to the compression chambers by means of check valves, the lower surface of the septum is made of a curved streamlined shape, the air manifold is formed throughout its internal cavity, and the configuration of the bottom of the housing has the shape of two connected cylindrical surfaces with different radii of curvature, with a large surface located on the sea side, while the consumer is made in the form of turbo-generator is installed on the air manifold. In the bottom of the case can be installed valve for filling with water the internal cavity of the housing, which improves the reliability of the installation by immersion under the water level.

Alternatively, the wave energy installation is achieved can be directly connected to the compression chambers, the consumer in the form of a turbo-generator with turbine unilateral rotation and installed within the air manifold and the surface of the working fluid is covered with a layer of mineral oil.

In Fig. 1 shows an installation, General view; Fig. 2 - installation in plan; Fig. 3 - installation, fixed to the bottom of the 4 piles; Fig. 4 - set in working position; Fig. 5 and 6 embodiments of the set the second surface of the bottom 2, the configuration which has the shape of two connected cylindrical surfaces with different radii of curvature R1and R2and from the sea the radius of the circle R2more R1. The housing 1 is partially filled with the working fluid 3. Inside the housing 1 is made hollow vertical partition 4, which is achieved. In the lower part 5, the baffle-air manifold 4 are curved streamlined.

Partition 4 divides the housing 1 compression chamber 6 and 7 are hydraulically interconnected and having a suction air valves 8 and 9. Partition-air manifold has inlet valves 10 and 11 for the compressed air.

Installation under the action of waves is rotated relative to the hinge 12, which is located in the center of the housing 1.

Installation is attached to the bottom using the anchor device 13, or fixed by means of scored in the bottom four piles 14 (which guides hinge 12 at the tides-the tides).

In the bottom 2 of the housing 1 is mounted a valve 15 for flooding hull seawater with a substantial excess of the estimated wave. The air manifold is mounted turbine generator, consisting of an air turbine 16 and the generator 17.

With the passage of the trough is a similar operation, but in this case, the chamber 6 becomes a compression chamber, and the camera 7 camera suction air. The air manifold 4 provides the pressure leveling before the air turbine of the turbogenerator when changing cycles of the cameras 6 and 7.

When approaching waves exceeding the calculated, installation flooded by intake of sea water through the valve 15 (or remotely with the remote control). The orientation of the wave front of the installations can be done by adjusting the lengths of 4 flexible fasteners 13 automatically or manually.

To further simplify the design wave installation can be performed on wares completely missing valve for intake and exhaust. Air or any gas that fills the chambers 6 and 7 are moved from chamber to chamber through the air manifold 4, which in its walls are openings 18, United nozzles with air chambers 6 and 7. Inside the air manifold 4 is set to the turbine with the turbine unilateral rotation.

In order to reduce the moisture constant volume of the gas in the compression chambers, the surface of the working fluid is covered with a layer of mineral oil.

Wave setup can be assembled in the United garlands with simple mechanical Association and the Association produced by the compressed air piping for use of a single turbine and generator or compressed air to shore for applications in power or refrigeration.

When approaching storm installing flooded by manual or remote (remote control on the shore) lift valve 15. After the passage of the storm, the setting returns to its working position by feeding compressed air into the body 1 (for example from a boat).
