The invention relates to hydraulic engineering, and more specifically to structures using wave energy to generate electricity.

The applicant known prototype of the claimed invention, as the closest to him on essential features. This prototype is a wave, hydroelectric, using the power of wind waves, which includes the dam, which separates the part polnoformatnaya waters with a pressure wall which has an inclined slope from the waters with a crest above its average level, and the unit consisting of turbines and hydro generator (Itwill, AUAR. Renewable sources of energy. M, Energoatomizdat, 1990, page 317, RIS, prototype.)

A disadvantage of the known device is the instability of the work unit associated with the random nature of the formation parameters of wind waves, which does not ensure stable operation of the unit and does not allow to directly use the electricity generated that requires the use of transducers its voltage and frequency.

The technical result, which is aimed by the invention is to improve the reliability and stability of operation of the unit by creating the current pressure regardless of the wind the s waves.

The essence of the invention lies in the fact that the wave hydroelectric power plant that uses the energy of wind waves, which includes the dam, which separates the part polnoformatnaya waters with a pressure wall which has an inclined slope from waters, with a crest above its average level, and the unit consisting of turbines and hydro generator, equipped with an additional dam, forming the second pool, which features a hydraulic unit, in ground swimming pool features a water-lifting device supplying water to the second pool to the first pool, and the overflow wall is from junction dam to the shore polnoformatnaya waters, and in as a water-lifting device can be used a hydraulic pump coupled to the turbine, or hydraulic RAM.

Fig.7 is a transverse section through 5-5 of water-lifting device using a hydraulic RAM.

Wave hydroelectric power plant, located in polnoformatnaya waters 1, part of which forms a pool 2, separated by a dam 3 with pressure wall 4, which has an inclined slope 5 from the side of the water area 1 and the comb 6, located above its average level, includes a dam 7, forming the second pool 8, which features a hydraulic unit 9 consisting of a turbine and hydro generator. In the first pool 2 set water-lifting device, which can be used hydraulic pump 10 connected to the turbine 11, or hydraulic RAM 12, which includes the pipe 13, is placed in pool 2 and connecting it with the water area 1, mounted on the end of pipe 13 air boiler 14 is attached to the pipe 15 connecting the air boiler with a second pool 8.

Unit 9, made in the form, for example, capsule, installed in the structure 16, which is part of the dam 7 and withstand the water pressure of the WTO the CSO basin 8.

The hydraulic pump 10 is installed in the structure 17, which is part of the dam 7, perceiving the water pressure of the second pool 8. The flow path of the hydraulic pump 10 connects the pools 2 and 8. The turbine 11 is installed in the structure 18 that is located between the pressure wall 4 and the structure 16 placement unit 9, which treats the water head first pool 2. The flow path of the turbine 11 connects the pool 2 and waters 1.

Water-lifting device in the form of a hydraulic RAM 12 posted by landfall, dam 3, opposite the junction of the pressure wall 4, and is installed in the structure 18.

In the drawings:

UVA - the average water level of the water area 1;

Macsoup and Minuit - maximum and minimum water levels of the first pool 2;

Macaws and Minumum - maximum and minimum water levels of the second pool 8.

Does the wave hydroelectric power plant is as follows.

With the emergence of wind waves in the surface waters 1 is the forward wave on an inclined slope 5 pressure wall 4. When increasing the intensity of the excitement comes a time when the height of the forward wave becomes higher than the ridge 6 of the pressure wall 4 and the water begins to flow into the pool 2, filling it. The water level in the pool 2 rises above the level of UVA waters 1 and forms a pressure equal to p is snasti these levels.

When used as a water-lifting device hydraulic pump 10 under the action of the educated in the pool 2 head starts to operate the turbine 11, resulting in a rotation of the hydraulic pump 10, which delivers water from the pool 2 pool 8, filling it. When the water level in the second pool 8 position Miowb included in the operation unit 9, which has a range of water levels in pool 8 of Miowb to Macaws. The size of this range is determined by the technical parameters of the unit 9. The rise in water level from Miowb to Macaw occurs in a period of intense unrest in the water area 1, when the flow rate of the hydraulic pump 10 exceeds the flow rate of the hydraulic unit 9. Decreasing the intensity of the unrest in the waters of 1 volume of water stored second pool 8 between levels Macaws and Miowb provides the hydraulic unit 9 in a period of low intensity disturbances or its complete absence in the waters 1. The placement of water-lifting devices in the form of a hydraulic pump 10 to the turbine 11 in the pressure wall provides them with the maximum water level at the inlet in the suction inlet of the hydraulic pump 10 and the receiving hole of the turbine 11, thereby providing the greatest performance of water-lifting device.

When used as a water-lifting device hydraulic who who Tarana 12 getting started comes also after the formation of the head between the water levels in the basin 2 and basin 1. When the occurrence of water hammer in the pipe 13 water enters the air boiler 14, compressing the air. When the air pressure in the air the boiler 14 reaches the value of pressure in pool 8 on the RAM 12, the water pipeline will begin to flow into the pool 8, filling it. The operation unit 9 when used as a water-lifting device hydraulic RAM 12 will be similar to those described above for water-lifting devices in the form of a hydraulic pump 10 to the turbine 11. The placement of the hydraulic RAM 12 from the shore, opposite the location of the pressure wall 4, and enables the use of straight pipe 13 with a minimum hydraulic losses and placing her entry into the zone location of the pressure wall 4, where during the filling of the basin 2 is the maximum water level and, accordingly, the maximum pressure used hydraulic RAM 12.

Water-lifting device in the form of hydraulic pump 10 to the turbine 11 has a high value of the coefficient, which ensures its high performance. The disadvantage of this option, water-lifting devices is the need to create a relatively high pressure for inclusion in the work and the high cost of equipment.

Water-lifting device in the form of side hydraulic the ski battering RAM 12 has the simplicity of the equipment used and requires little capital investment and can work with minimal pressure. The disadvantage of this option, water-lifting device is its low efficiency, which can be 3...4 times less than the coefficient of water-lifting devices in the form of a hydraulic pump 10 to the turbine 11. The choice of the type of lifting device is determined by technical and economic calculations.
