Figure 1 shows the General location of the installation in the reservoir, and float in working and safe positions.

Figure 2 presents the type of support with on her equipment.

Figure 3 presents a view of the float and the mount oscillating rod to a support.

Wave power plant (figure 1) includes a vertical support 1 mounted on the bottom of the reservoir. Vertical support 1 is installed so that its upper edge with a fortified it rocking rod 2, was under water at any likely power disturbances. Rocking rod 2 mounted on a vertical support 1 so that the ratio between the shoulders rocking rod 2 comprises about 10 to 1. On the long end of the rod attached to the float 3. On the vertical support 1 (figure 2) wearing open bottom of the Cup 4, mounted on a vertical support 1 by means of bearing the units 5, being formed in between the glass and the vertical support air cushion. Also on the outside of the Cup 4 is fixed to the pump 6, mechanically associated with short arm swinging rod 2. The pump 6 through the pipe 7 is connected with hidropneumoacumulatorul 8, located on the shores protected from adverse environmental factors. Turbine 9 is connected with hidropneumoacumulatorul 8 through the valve constant pressure. The drain pipe 10 with one end connected to the outlet of the turbine 9, and the other goes into the pond. In the float 3 (figure 3) have upper and lower openings, provided with adjustable valves 11 and 12. Also in the float 3 has a hole with attached pneumological 13, which is connected with a source of compressed air 14. Adjustable valves 11 and 12 are connected with the force sensor excitement, made in the form of the pressure transducer 15, located on a rocking rod 2, near mount swing rod 2 to the vertical pole 1.

The drain pipe 10 can be combined with the pump 6 and hidropneumoacumulatorul 8 in a closed loop, which may reduce the efficiency of the system, but will be used in the circuit is chemically neutral liquid such as fresh water, which will increase the durability of the installation.

Also the force sensor excitement can be implemented in the form of angle sensor the new position of the swinging rod, either in the form of a sensor of angular acceleration, located in the rod or float. The force sensor excitement can be implemented in the form of a pressure sensor in the pump. Due to the fact that the generator can be isolated from the adverse effects of the external environment on the Bank increases the reliability of the entire installation as a whole.

Wave power plant works as follows: under normal conditions of the external environment rocking rod 2 with the float 3 freely rotating and swinging about the vertical support 1, with upper and lower adjustable valve 11 and 12 are closed. In this mode, the underwater part of the installation due to mechanical movement of the float 3 moves with the help of the pump 5 water pipe 6 in hydropneumoaccumulator 8, and then the flow of water passing through the turbine 9, produces energy. Under adverse external conditions, such as excessively severe turbulence or wind receives the signal from the sensor 15, the opening adjustable valves 11 and 12 in the float 3. The float 3 is filled with water, becomes negative buoyancy, and the swinging rod 2 with the float 3 is immersed in a position not subjected to significant dynamic loads with excitement. At lower power disturbances to an acceptable force sensor 15 sends a signal to close the upper valve 12 and Apodaca compressed air in the float 3 and the air supply 13 from the compressed air source 15, water is displaced from the float 3 float 3 becomes positive buoyancy and begins to work in normal mode. Some time after the beginning of the compressed air in the float 3 is closed the lower adjustable valve 11. Thus, if the maximum allowable stress wave power plant goes into safe mode. In safe mode all the main components are below the level of maximum impact unrest, thereby increasing the reliability of the installation. A wave power plant, located in safe mode more dynamically stable due to water-filled float.

Thus, the claimed invention was possible to obtain a technical result, namely to improve the reliability and durability of the wave power plant in the hostile environment.
