Description

The invention relates to the protection of the environment and can be used in the operation of reservoirs HPP-PSP.

The aim of the invention is to intensify the process of mixing the surface layer of water.

FIG. 1 shows a hydropower facility, a section; FIG. 2 — node I in FIG. one.

The device for implementing the method includes an elastic diaphragm 1 fixed on the float 2, which is connected to the pontoon 5 with nuts 4 and nuts 4. A winch 6 is installed on the pontoon 5, which controls the cable 7 thrown over the block 8 and fixed on the bottom with a bark 9. The internal cavity 10 of the float is connected by a hose 11 to the compressed air point located in the hydraulic unit 12.

The method is carried out as follows.

Compressed air is supplied through the ice 11 "cavity 10 of the float 2, which floats from the bottom to the top of the water, (float 2 with a pontoon 3 with no Oiub; o t g 3 and nuts 4, wind the cable 7. fixed with one end for measles 9. through the block 8 into the winch 6. Then the cable is pulled by the winch, as a result of which the device takes the position indicated in Fig. 1. The hydraulic unit 12 is turned on into the turbine mode, as a result of which water rushes into the gap between the float 2 and the pontoon F entrained phytoplankton accumulated on the surface in aggregate 12 and further downstream. The thickness of the interacting surface layer with the help of nuts 4 changes the length of the tooth pitch 3 and 3, thereby changing the gap between the pontoon and the float. When converting the unit 12 to the pumping mode of operation, the gap between the pontoon and the float is adjusted to the required the parameters of the surface layer, after which the unit is included in the pump.

Use: Invention allows effectively cleaning the surface of a body of water from phytoplankton accumulations, providing, at a gurbin.m operation mode of units 12: ES-HAES, water intake and phytoplankton 13 upper warm layers, where it observes-: mode - supply of cold air-:) water from the downstream to the surface layers of the upstream. In this case, there is an intensive mixing of the upper layer of water, an improvement in its oxygen regime and a decrease in the amount of phytoplankton. By changing the thickness

The surface layer directed to the unit regulates the process of cleaning the reservoir.
