The inventive coastal performed the basin formed by the casing-dam with the inlet plate valve and the outlet flow channel with turbo-generator. The inlet valve is mounted above the housing-dam and attached hinge. The plate valve is made with a positive buoyancy and is made of at least two parts, pivotally connected to each other. The exit of the exhaust flow passage is made in the form of a vertically positioned pipe with vypuklym valve on the end. 1 Il. The invention relates to marine energy installations and can be used to produce electricity with the help of the waves.A device for wave energy, including the enclosing wall of the inclined surface and the reservoir. To increase the height of the forward wave wall edge has a tapered channels formed transverse dams.The disadvantage of this technical solution is relatively small efficiency.Closest to the invention technical Vanny body-dam with the inlet plate valve and the outlet flow channel with turbo-generator.This device can generate electricity on this coast, where there are no distinct tidal, because during high tide, the device is hidden under the water and lies dormant.The technical result of the invention increase the efficiency of the installation by using in the sea tide.This technical result is achieved in that the inlet valve is mounted above the housing-dam and attached via a hinge, the plate valve is made with a positive buoyancy and is made of two or more parts pivotally interconnected, and the output from the exhaust flow passage is made in the form of a vertical pipe with a valve on the end.Spastically analysis of the claimed Maritime power plants, analogs and prototypes showed that their common feature is the presence of the completed coastal basin, formed by building-dam with the inlet plate valve and the outlet flow channel with turbo-generator.Differences declared marine power plant from analogs and prototypes are that the inlet valve is mounted above the housing-PL is in two or more parts, pivotally connected to each other. The output of the flow channel is made in the form of a vertical pipe with a valve on the end. Significant new features allow you to increase efficiency by automatically changing the height of the inlet valve in the conditions of the sea tide.Comparative analysis shows that the requested installation is new, involves an inventive step and is industrially applicable.The drawing shows a marine power installation, side view in section.It consists of a body-dam 1 flow-through channel 2, a turbine 3 and a generator 4 connected through the shaft and gear. Above the body-dam 1 has an inlet plate hinged valve 5 with positive buoyancy, and the output of the flow channel 2 has an exhaust valve 6. The exit flow channel 2 is made in the form of a vertically positioned pipe 7. Inlet swivel valve 5 is serially connected with him through a hinge 8 plate 9 with positive buoyancy. Plates 9 may be several depending on the height of the level difference of the tide.Marine energy installation low tide works thodic to the body of the dam 1, closes the exhaust valve 6 and rolls into the pool through the plates 5 and 9. The water level in the pool rises, the plate 5 POPs up and takes a position close to the vertical, overlapping over a body-dam 1 reverse flow of water from the pool, and the plate 9 continues to lie horizontally. The resulting difference in water levels on both sides of the body-dam 1 opens the exhaust valve 6 and is used for operation of the turbine 3 and the associated generator 4. After the water levels on both sides of the body-dam 1 will be equal, the plate 5 is horizontal. The next tidal wave closes the exhaust valve 6 rolls through the plates 5 and 9, and the cycle repeats. The pipe 7 serves to guide the flow of water up, not to destroy the next tidal wave.In the mode tide of marine power plant works as follows.The water level rises and the plate 5, surfacing, takes a position close to the vertical, and the plate 9 remains lying horizontally on the water even when the tide it top marks. Tidal wave rolls through the plate 9, the water level in the pool rises and the plate 9 becomes VERTIC is rpusa-dam 1 water passes through the turbine 3, the water levels are aligned and the plate 9 is horizontal. The next tidal wave rolls through the plate 9, and the cycle is repeated with appropriate operation of the valve 6.The effect of operation of marine power plants is due to the fact that it can work in the coastal zone of all the seas and oceans as a constant water level and tidal conditions. The inlet valve 5 with the plate 9, having a positive buoyancy and installed above the body-dam 1 maximize the difference in water levels at the base of the dam, and the presence of the socket 7 of the flow channel 2 helps to weaken the approaching tidal wave. When the direction of pipe selected vertically upwards, as the direction it down can cause erosion and sedimentation housing-dam 1.Number of buildings-dams along the coast can be unlimited, and the extreme of them are connected with the shore by watertight bulkheads, forming a pool with a high water level. The wall of the pool, walking along the shore and installed in the water will protect coastal soil from the impact of waves of the surf. MARINE POWER INSTALLATION, the valve and the outlet flow channel with turbo-generator, characterized in that the inlet valve is mounted above the housing-dam and attached via a hinge, the plate valve is made with a positive buoyancy and is made of at least two parts pivotally interconnected, with the exit of the exhaust flow passage is made in the form of a vertical pipe with a valve on the end.

SUBSTANCE: invention relates to small power engineering for transforming the flow of rivers and tides into angular kinetic energy on free-flow link hydroelectric power plants. The hydro-turbine consists of a hollow carrying shaft-cylinder with adjustable ballast, which makes it possible for the hydro-turbine to be fully submerged into water or bring it to the surface. On the shaft-cylinder are placed semi-cylinder arms, to whose ends are attached annular containers with ballast, which ensure neutral buoyancy of the hydro-turbine. On the shaft-cylinder are mounted equally along its length several discs or flat cylinders with grooves on the rims, to which are attached arms. Arms have the shape of the lateral sides of the hollow cylinder, cut-off longitudinally, thus, so that the discs are inscribed on the inner ends of the arms. A central hole is formed between the discs, of the surface carrying shaft-cylinder and the inner ends of the arms, through which communicate all vane spaces. As a result the flow goes through the entire turbine, touching the arms, which are located on the rear from the flow of the turbine end. The outer ends of the arms are tightened by rings-hoops and will form a multibladed cylinder, whose base is fully closed with the containers of ballast, tightly joined with the ends of the arms and hollow carrying shaft-cylinder.
EFFECT: hydro-turbine has a high coefficient of efficiency and is simple to produce.

The operating blades are bent relative to each other and provided with hinge in the point of bending. They are installed on the external side of endless band along the whole its length. The stabilisers are installed on drum shafts outside the body boards. The said stabilisers pull down endless band with blades with regard to the body bottom to activate part of the blades in the upper part of endless band during high-tide. Alternatively, the stabilisers lift the endless band to activate part of the blades in the lower part of the endless band during low-tide.
