DEVICE FOR SUPPLYING SURFACE WATER INTO DEEP LAYERS OF A WATER RESERVOIR

摘要

The invention relates to the protection and restoration of the biological resources of reservoirs, in particular, it is intended to combat fish blockages with a lack of oxygen in the byssal zone and a shortage of substances in the surface layer. The aim of the invention is to increase productivity by increasing the amplitude of movement and the time of water injection and the efficiency of aeration. Under the action of waves, the device makes vertical oscillations, while the movement of water inside pipe 1 below the check valve 4 as the device moves down is accelerated. Then the movement of the device slows down, and water flows out through the bottom of pipe 1. When the device passes waves, water enters the through hole 3 through the side channels 6, while the other side channels 6 that are above the water level of the reservoir are closed by non-return valves 7 The device delivers aerated water of the upper layers to the lower layers, which causes convective lifting of biogenic substances to the surface layers. 2 Il.
