The invention relates to hydropower, in particular to the wave energy installations.Known wave power installation comprising a fixed bearing and located between the sectional impellers.The disadvantage of the installation is its low efficiency. Known wave power installation comprising a body having the shape of a hollow torus and installed in the housing of the rotor.The disadvantage is the complexity of its construction. Known wave power installation comprising a set on the side floats and the side of the pontoon, United with floats articulated with tie rods.In this installation, the pressure of the working fluid at the turbine depends on the degree of fluctuations of floats, consequently, the rate of oscillation of the waves. Because the level of fluctuations of the waves is very irregular, the efficiency of the plant is low. In addition, the impact of electricity in the installation time is also very uneven, because there is no device, accumulating energy.The lack of installation - low efficiency.The purpose of the invention is increased efficiency.This objective is achieved in that the wave power plant comprises a movably mounted on interconnected lateral floats capacity with the working fluid located therein a turbine connected to a generator, and two side pontoons connected to the floats with tie rods.The difference from the prototype is that the installation is equipped with ratchet and transmission system, the connection of the lateral floats between them is made in the form of a support frame fixedly connected with the floats; a tank mounted on the frame for rotation in a vertical plane and is connected through a gear system with ratchet mechanismname tanks, evenly spaced around the circumference of one relative to another.In Fig. 1 illustrates schematically the wave power plant of Fig. 2 is a top view of Fig. 3 - wave power plant with three working tanks.Wave power plant comprises a lateral floats 1 and 2, which are connected by a supporting frame 3 is fixedly connected with the floats 1 and 2. Capacity 4 with the working fluid are mounted on the frame 3 for rotation in a vertical plane. In the vessel 3 is the turbine 5 connected to the electric generator 6. Two side of the pontoon 7 and 8 are connected with the floats 1 and 2 with tie rods 9 and 10. On draught at the side of the float 1 is mounted a ratchet mechanism 11. It is connected through a system of gears 12 and 13 (e.g., chain) with the gear 14, mounted on the vessel 4 with the working fluid. With the pontoon 7 is connected to the anchor line 15.On the supporting frame 3 can be installed in two or more containers 4. In this capacity 4 may consist of a set of individual containers, which are evenly spaced around the circumference of one relative to the other, with an angle between them. The container 4 is sealed and is filled to 75-80% of a liquid, such as water. Gerotor meuwese in the vessel wall 4. The generator 6 is fixed on the base frame 3.Wave power plant works as follows.When the oscillation of the side pontoons 7 and 8 thrust 9 and 10 begin to sway. Accordingly, vibrations may occur floats 1 and 2, interconnected by a supporting frame 3. The periodic rise of the floats 1 and 2 rocking support frame 3, increasing the pressure of the working fluid in the vessel 4 to the turbine 5. Ratchet mechanism 11 when the thrust oscillations 9 through the gears 12, 13 and gear 14 provides the rotation of the vessel 4 in one direction, when this occurs the flow of fluid from one part (blade) capacity 4 in another. If tank 4, the flow of the fluid is constant and the energy time-aligned.If necessary, the installation is attached to the anchor rope 15.The use of the present invention will increase the energy by 30-50% due to the use of the kinetic energy previously raised fluid, to provide a more uniform rotation of the generator due to the resultant action of swinging and falling of the liquid and to provide modular units. The location of the containers 4 on the frame 3 makes available the energy and so on 1.
