This device contains the submersible is hydrated in water body...". It holds the body in water devices and it is not clear how will this device be kept in submerged condition at the time of the tides. As can be seen from Fig. in the application SU 1020619 AND 30.05.1983, F03B 13/12, no device, in which two turbines are made with reflective screens, and the device is provided with valves-valves unilateral action". In addition, the device to use the energy of the sea tides (application SU 1020619 AND 30.05.1983, F03B 13/12, see Fig.) cannot serve as wave power and effectively to rotate (to work) at the expense of the waves, because the length of the sea waves can be different, and "shaft in the horizontal plane with screw wheels along its length, at a specific point in time, the wave will be in different phases. Another thing the tides, in which phase (inflow-outflow) change at 6 h 12 min (i.e., 4 times a day).

A disadvantage of this device is its complexity associated with the device gutters and side walls, and limited work in the opposite direction of the waves.
The closest in technical essence and attributes is patent No. 2349791 C2, 20.03.2009 "Submersible hydraulic turbines installed on deck (Tidal power), containing the vertical rack rails, cross members located between them, which is installed at a distance from each other two turbine unit, with the cross beam is arranged to move vertically in racks on the depth of the turbine depending on the height of the waves.
A disadvantage of this device is the lack of devices for guiding the water flow to the turbine, and the possibility of double work of turbine.
The objective of the invention is the simplification of the device and the expansion of the range and use it for conversion into electrical energy the energy of waves and tides.
The technical result - the possibility of obtaining electricity from waves and tides, as well as use as hydropower soo is ugenia.
The essence of the invention lies in the fact that the wave power plant comprising a vertical rack rails, cross members located between them, which is installed at a distance from each other two turbine unit, with the cross beam is arranged to move vertically in racks on the depth of the turbine depending on the height of the waves, according to the invention additionally contains two dams for the passage of the waves between them, reflecting screens, directing the water flow to the turbine and mounted on the cross beam, made in the form of metal truss, and valves-valves unilateral actions that are installed on the ends of the dams, when the turbine is made with the possibility of one of them during the motion of the waves to the shore, and the other from the shore.
Wave power plant can operate as a tidal power plant in the presence of pools on the shore.
In Fig.1 schematically shows a wave power plant (top view), where 1 is a longitudinal dam, 2 - rack rails, 3 - cross-beam, 4 - turbine unit 1 (TA1), 5 - turbine unit 2 (TA2), 6 - reflecting screens, 7, 8 - valves-gate, 9 - pool (when using the device for converting energy of tides)
In Fig.2 and 3 are given the axonometric image of the wave power plant at the position the valve is in the shutter when the surf wave (at high tide), and when the movement of the waves from the beach (low tide), respectively.
Wave power plant comprises a concrete or cannabaceae guides flows longitudinal dam 1, which has two vertical rack rails 2. Between the longitudinal dams 1 stacked transverse beam 3. It has two turbines (TA) 4 and 5. As shown in Fig.1 and Fig.2, between them (dam and guide beam) are reflective screens 6 to direct the flow of water to the turbines. The transverse beam 3 with THE 4 and 5 can move vertically on the uprights 2, changing the depth of immersion of turbines depending on the height of waves and tides. The device has valves-valves 7 and 8, located on different ends of the dams. The device may also include pool 9 (see Fig.1-3) when it is used to convert the energy of the tides.
Wave power plant operates as follows.
When the movement of the waves on the beach (the tide) valve-gate 7 is closed due to the waves (tide), and the wave passing between the concrete or cannabaceae dams 1 and reflected by the reflector 6, narrowing the passage and concentrating the energy of the wave falls on THE 4, which generates electricity. The shutter 8 is opened due to the energy of the wave (tidal), and water wave passes to the shore (the water is in the pool when this device is used to convert the energy of the tides). And when the movement of the waves from the beach (the tide of bass is in) valve 8 is opened, the movement of the waves. Water passing between the levees back from the shore and narrowing the passage through the reflector 6, falls on THE 5, which generates electricity. Further, the valve 7 opens through the current of water from the beach (low tide), and the water falls back to the sea. Depending on the wave height (the height of the tide) transverse beam 3, along with established THAT 4 and 5 is moved vertically on the uprights 2, changing the depth of immersion of the turbines, which allows to extend the range of wave and tidal energy devices.
Thus, the valve 7 in the direction of the wave motion of the sea to the beach (the tide) is closed, and from the beach (low tide) is open. Valve 8, on the contrary, when the motion of the waves to the beach (the tide) is open, and from the beach (low tide) is closed. And the turbine unit 4 operates with the movement of the waves to the beach (the tide), and the turbine unit 5, on the contrary, from the beach (low tide). Wave power plant will also absorb part of the energy of the waves, taking their devastating impact that can play the role of coastal defences.
The advantage of the proposed wave power plant in its simplification: through the use of local materials; simplicity of construction and use of standard structural elements; and efficiency: by expanding the field of use (conversion of energy waves, tides, as well as coastal defences); u is the situation in different parts of different longitudinal dams valves-valves and possible vertical movement of the transverse beams with the turbine, changing the depth of immersion of the turbines, which allows to extend the range of wave and tidal energy devices and to optimize the performance of the turbine.
