Abstract

The invention relates to the field of hydropower and allows to increase the efficiency of the installation. The storage reservoir (GAI) 8 is located below the hydro-accumulating basin 1 and is limited on one side by the pneumohydro-accumulator 3. In GAU 8 there is a chamber 9 in which a hydro turbine (GT) 10 with an electric generator is installed, connected to the conduit 2. To a sealed tank (GR) 11, located at the bottom of chamber 9, is connected at one end to a drain channel 12, the other end of which is equipped with a check valve 13 and is located on the side of wave receiver 4. The waste water from the GT 10 is discharged into GR 11 and then enters through channel 12 sn a dyne waves. The rarefaction arising in GR 11 leads to an increase in the head height in the GT 10, to an increase in the energy output of the stored water in Basin 1 and GAI 8. 1 Il.

This invention relates to hydropower.

The purpose of the invention is to increase the efficiency of the installation.

The drawing shows a wave accumulator power plant, a section.

The wave accumulation power plant contains a hydro-accumulating basin 1 and associated with it by means of conduit 2 — pneumatic accumulator 3 with a wave receiver 4 facing the wave front and having upper 6 and lower 6 walls at an angle of which check valves 7 are installed, the installation also contains a hydraulic storage tank 8 located below pool 1 and bounded on one side by a pneumo-hydraulic accumulator 3, chamber 9 placed in tank 8 and installed in it at least at least one turbine 10 with an electric generator connected to the conduit 2, the chamber 9 is provided in the lower part with an airtight reservoir 11 and a drain channel 12 connected to it at one end, the other end of which is fitted with a check valve 13 and is located on the side of the wave receiver 4, The installation also contains a nozzle 14 connecting the pneumohydroaccumulator 3 with a hydroaccumulative tank 8.

The installation works as follows.

When a wave rushes onto the lower stack .6 of the receiver 4, the energy of the vertical oscillatory movement passes into the horizontal movement of water and its speed increases. Upper wall 5 contributes to the concentration of the movement of water, directed the crest of the ox

to the top of the intersecting walls 5 and 6, where a sharp increase in pressure occurs. Under the action of water pressure, the valves 7 open and the water passes through the pneumohydroaccumulator 3, increasing the pressure of the air in the upper part. When the wave departs, the air pressure in the pneumohydroaccum

The valve 3 closes the valve 7 and pushes the water through the pipe 14 into the pump storage tank 8, and with a large wave energy storage and high pressure in the pneumohydroaccumulator 3, through the water line 2 into the pumped pool 1 and into the hydro turbine 10.

From the storage tank 8, water flows to the turbine 10. The waste water from the latter is discharged into a sealed tank 11 located in the lower part of chamber 9 below 5 hydro turbines 10. From tank 11 along drain channel 12 through a check valve 13 water enters the troughs of the waves, thus the water level in the hermetic reservoir 11 decreases, in which a vacuum occurs, leading to an increase in the height of the head in the hydro turbines 10, to an increase in the energy output of the stored water in the reservoir, 1 and the reservoir eight.
