"Wave power", patent of Russian Federation №2405967, F03B 13/18, 10.12.2010,) consisting of a number of hollow sections, installed longitudinally in a row close to each other and placed inside between the vertical boards. Shields hung butt inside two parallel rows of hammered into the bottom of the pile. On the upper ends of the piles stacked supporting beams, which are mounted shields. The section is made in the form of a straight hollow four-sided prisms open bottom, in cross section having the shape of a rectangle. In the upper part of the section has two end-to-end lengthwise of the window formed by the upper plate, side walls, internal oblique and vertical partitions. Vertical partitions are rectangular Windows with internal grooves for intake and exhaust valves. The valves are inserted from above through the hole in the top plate. Themselves valves are exactly the same, made in the form of a rectangular frame with horizontal baffles, which on the one hand lapped attached strips of soft material such as rubberized fabric, rubber or synthetic material. On three sides, at the bottom of the IEP the sides of the frames have protruding ribs, designed for fixing and proper orientation of the valve in the Windows. For proper orientation of the valve in the Windows in the slots of the Windows are inserted U-shaped mounting frame. Assembled box form an aerial highway and depending on which way you turn the valve, the line will be injection or suction. For sealing air lines, formed by Windows along the perimeter of the Windows fasten the gasket. As during operation in the discharge line will inevitably accumulate water, to remove it at the base, in front of the air inlet pipe, there is a well and a valve with a float. The assembled structure is a pier or breakwater, and may optionally be used. From the shores of the structure is supported on a concrete Foundation, with the sea at the end of construction, there is the fairing that protects the front end from the shock waves.

A disadvantage of this device is its complexity - contain a large number of items, highways and seals, which have a limited service life.

Known tidal power plant (A. L. Yakovenko in. A. Sharov, A. M. Naverniuk and other "Tidal power", patent of Russian Federation №2361038, IV 9/08, F03B 13/26, 10.07.2009,), comprising a housing with an open input and output has the s on the vertical shafts of rotation, associated with generators, turbines in the form of reels, on the outer surfaces of which the fixed blades. On the inlet and outlet of the body has vertical panels that direct tidal flow on the blades of the turbines and provide their rotation. Representing the turbine drum consists of the United bases of the two cones on the outer surface of which a spiral line attached blades. The beginning of each blade on the bottom of the top cone drum is displaced in the course of its rotation relative to the end of the blade to the top of the second drum for 1-2 step of the blades. The lower conical section of the drum, the blades are in the form of rotation in the form of a cylinder, and in the upper part of the drum blades repeated during the rotation of the cone shape, enlarged to double the size of the blade. The lower conical section of the drum, which is 1/3 the total height of the drum, the number of blades twice its size, and the width of the bore hole between the drums in the lower part equal to twice the size of the blade at the junction of the bases of the conical drum. Rotatable vertical rod tidal shields installed from the longitudinal axis of symmetry of the hull on both sides at a distance not greater than the diameter of rotation of the lower part of the drum, and the tide of the shields from the lateral side of the housing at a distance equal to the radius of rotation nor is it part of the drum.

The disadvantage of this tidal power station is the complexity of the device and that it is unilateral actions

Known wave power plant (C. C. Glushchenko. "Wave power plant", author's certificate No. 1574895, F03B 13/12, bull. No. 24, 30.06.90 g) containing the input Anoprienko device made in the form located above the water level trough that is connected to the storage tank unit. In addition, the plant is equipped with additional Anoprienko gutters that are attached to the side walls of the main chute, the side walls of the primary and secondary chutes equipped with sloped to the water level planes, and all the gutters are installed with an inclination in the direction of the water tank. Gutters and planes made from the same type of reinforced concrete sections and installed on the piles. Gutters can be placed around the tank.

The disadvantage of this setup is its complexity and the need for device gutters and tanks.

The device to use the energy of the sea tides (application SU 1020619 AND 30.05.1983, F03B 13/12) has "a body immersed in the water..", "butterfly valves" and "...in the horizontal plane of the shaft with a screw wheel kinematically interconnected...". 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).

It is also known a device for wave energy (R. B. Rabinovich. "Device for wave energy", copyright certificate №1206472, F03B 13/22, bull. No. 3, 23.01.86 g), which contains the receiving groove of variable width and a camera installed in her by the turbine, and the width of the trench decreases towards the camera. The device is also provided adjacent to the groove of the pad placed on its side walls, in the beginning of the square and a check valve, and the receiving groove provided with an inclined top, and its gradient is directed towards the turbine chamber. The check valve may be in the form of a shutter pivotally hung on the walls.

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.

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, characterized in that the wave power plant further comprises 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.
