The invention relates to the field of hydropower, namely, the energy Converter of the waves and the constant currents and river flow into electrical energy, while performing the function of the idler waves and coastal protection.

There are many plants, transforming the energy of sea waves and tidal currents into electrical energy.

Such transducers include "Primobol Masuda", made in the form of an open bottom pipe, a vertically submerged in water and having in the Central part of the body of the pneumatic turbine, which serves one-way air pneumatic valves, and kinematically associated with the generator (Whakarongo. The energy converters of the ocean. - Leningrad: Sudostroenie. 1986, s-150).

A disadvantage of the known device is its low efficiency, related to the fact that the intake and expulsion of air used a small part of the static pressure passing wave, and the device itself materialstrategy.

Known engine for energy recovery current environment containing immersed in the last frame with bushing Windows, shafts, one of which is kinematically connected to an electric generator, a flexible element covering the said shaft and provided with blades mounted thereon can be rotated around the axis of the vane is, the frame is placed on its longitudinal side across the flow of the current environment, and with the blade interacts with the environment to change their position on the said flexible element on the opposite (EN, No. 2166664, MCL.7: F03B 9/00, 2000).

The known device cannot be used as a wave hydro power plants, due to the fact that it is not fit for work under the influence of tidal and oppositely directed tide waves or require additional mechanisms turn the device 180 degrees.

The closest technical solution is selected as prototheca is pneumatic Converter, comprising a housing with a turbine generator and vanaprastham hole in the lower portion of the side wall, where in areas likely shock waves holes, ending with hydraulic gates in the form of V-shaped grooves (RU # 2230852. M. CL.7: IV 9/08, 2000).

A disadvantage of the known device is that it is stationary design, tied to the shore and complicated to manufacture, has a low efficiency pneumatic energy conversion waves.

The energy Converter of the flow of water into electrical energy, which can be used both during high tide and low tide, set its length along the flow direction, and b has the skoneczny element, zapasovany in the wheel-drums, shafts which are kinematically connected with the generator, on the outer side of the endless element evenly with folding blades (JP 2004138015 A, 13/05/2004, F03B/900).

The aim of the invention is to increase the efficiency of the device due to the higher efficiency of conversion of wave energy, simplifying the design and operation of the device, expanding the range of use, sea tides and low tides in rivers constant for any of the available depth or artificial channels, taken parallel to the natural bed.

The proposed device is significantly expands the scope of its application, making possible its placement, even under the ice.

The invention consists in that the energy Converter of the flow of water into electrical energy includes a housing with a wall of Windows in the lower part of the ebb and the upper part of the tide, an endless belt located inside the housing and zapasovany drums. Rotor blades in the form of two shoulders plates bent relative to each other, with the hinge in place bend, mounted on the outer side of the endless belt along its entire length. Stabilizers are installed on the shafts of the drums for the hull sides and provide a lower endless belt with blades relative to the bottom of the housing for the pressure in the working part of the blade on the upper part of the endless tape at high tide or her rise to be included in the part of the blades on the lower part of the endless belts at low tide, while the body is made of vertical slots regulating the height of the lowering and lifting. At the end of the housing is fixed a movable shutter to guide the flow in the upper part of the endless tape at high tide and receiving a horizontal position for unobstructed flow during low tide.

The Converter is designed for tidal currents, contains installed at a certain angle to the line of motion of the waves on the axes of the drums stabilizers, and the axis of the drums move freely up and down in the vertical slots in the housing of the device by the amount of opening of the blades in the lower pass-through device Manager.

In order to more fully use the most energetic of the surface phases of the waves, the device has a vertical slot 8, which is placed on the axis 4 of the drum 3, axis 4 is also fixed stabilizers.

Between the reel is sealed cavity for installation of generators and other equipment, and the top and bottom plane of the cavity additionally perform the function of retaining guides for the tape with the blade, eliminating the deflection of the ribbon under the weight of the water.

The proposed Converter the energy of sea waves into electrical energy is illustrated by drawings, where:

Figure 1 is a General side view of the transducer in a position corresponding tidal wave down n the sending gate.

Figure 2 - side view corresponds to a tidal wave, when the flow of water takes place in the lower part of the housing and the shutter in a horizontal floating position;

Figure 3 - view of the transducer from the end side of the tide, where visible stabilizers on the axes of the shafts.

The Converter consists of a casing 1, having at the ends above and below the axis of the drums, the feed-through window 2, which is placed zapasovany in the drum 3 mounted on axes 4, kinematically connected to an electric generator, an endless element as elastic tape. At last, throughout its length, an outer surface, set the blade 6 in the form of two shoulders of the plates bent at an angle of 110-120°, from the pressure of the flow, with the hinge at the knee, made of the conditions of folding blades on the flexible element as it moves against the direction of the waves.

In order to more fully use the most energetic of the surface phases of the waves Converter has a vertical slot 8, which is placed on the axis 4 of the drum 3, axis 4, with the outer sides of the body, also anchored stabilizers 9, which automatically calculated the height of the pressing device to the bottom of the Cabinet in a tidal wave and lift the device up when passing through the bottom of tidal waves. Between the drum 3 is placed a sealed cavity 10 where the top 11 and bottom plate 12 serving as the supporting guides for the endless belts 5 (figure 3) with the blades 6. At the end of the body 1 at the level of the axis 4 of the drum 3 from the side of high tide is mounted movable horizontal shutter 13 in the wall 14 with the top curly sink 15 by the tide, and the tide window fully open.

On the axes of the drum 3 is installed under the estimated angle to the horizontal stabilizers 9, of the conditions for diving or surfacing rotating part of the transducer relative to the bottom housing to the specified slot 8 level. With the passage of the wave top torque of the device is pressed on the calculated value to the bottom of the housing without interfering with the passage of passive blades, and when the tidal wave of torque portion is raised relative to the housing to a height sufficient for movement to the opened blades 6 in the flow of water. For this purpose the side walls of the casing, in the area of the output axis of the rotating drum 3, is made of vertical slits 8.

At the level of the axis of the drum 3, on the end of the body 1, from the tide, placed horizontal shutter neutral buoyancy 13, with the possibility of lowering all the way to the bottom at high tide and making automatically a horizontal position at low tide to ensure the smooth passage of tidal waves (1, 2, 3).

Does the Converter as follows.

By the action of the device of the tidal wave, the last occurring in the upper pass-through window 2 through figure plums 15, between the CTE is the kami of the housing 1, devotes all his energy through the blade 6 of the infinite element 5, the rotating drum 3 axles 4, and through them and the reduction rotates the electric generator is placed in a sealed cavity 10. When the movable shutter 13 is pressed by the flow of tidal waves to the bottom, creating a flow direction in the upper part of the tape on the blades 6 in the working position. Blades that fall in the lower part of the transducer, using a special roller and the partial impact of the oncoming flow, the system adds the entrance of the cavity along the guide 12, reducing resistance to flow in the housing 1. When moving in the opposite direction (at low tide), to meet the wave, the blades 6 in the upper part of the endless element 5 are formed by means of the hinge 7, providing the minimum resistance to movement of the element 5, and the entire torque of the device under the influence of hydrodynamic pressure on the stabilizer 9 is lifted so fully revealed in the working position of the blade 6 in the lower part of the housing, the rotating element 5 in the same direction. The level of the axes of the two drums and the height of rise of the torque depend on the dimensions of the slots 8 on the side walls of the housing. The energy of rotation of the drums in any known manner is transmitted in the hermetic cavity 10 on the generators. When the strength of the flux and reflux device is about can have dimensions, for example, in length from 3 to 12 m and width up to 2.5 m, with any number of installed units in the flow, limited only hydrological conditions of the lagoon to the sea or river.

In a variant of the device designed for continuous flow in rivers and bottom currents or artificial channels, the device does not need stabilizers 13 of the slot 8, as there is no need for the lifting torque of the device relative to the housing. In this case, the manufacturer and device operation are simplified. Through the front wall 14 and figure of the guide 15, the flow goes directly on the blades 6, where a portion of water contained between the hull sides and infinite element 5, the pressure on the blade, rotating drums, which in turn transmit rotational energy through actuators (not shown) to the generators, housed in a hermetic cavity 10.

If the flow of the river is very small, the Converter may be due to the retaining wall of one or more devices arranged in a row across the stream, to create an artificial need afflux of water level and to ensure a normal operation of the generator. At very low pressures in rivers or on the chutes, the device can operate at low tide, i.e. is water in the lower part of the housing and the working blade located at the bottom, and a passive position folded Lopato is, located in the upper part of the hull, above the water level in the river, in this situation, the device may use the height of the flow even from 0.1 m (not shown). The width of the river (or river) can accommodate multiple devices, blocking at least all the way, and if you want to use only one device, use the device with an artificial dam. Blade 6 when folding in the passive part of the body rests on the front under the blade, i.e. on the support part, and to reduce the resistance of the water on the base part of the blade, it placed the bandwidth of the window.

The technical result, which is aimed by the invention, consists in a high system efficiency and wide range of use through better use of energy and tidal tide waves, bottom of ocean currents and river flows of any height level, flow, torque generator in the same direction. Their kinetic energy to the water stream gives directly without any additional mechanical energy converters, with the corresponding loss of efficiency.

The proposed device is significantly expands the scope of its application, making it possible placement, even under the ice.
