Description

The invention relates to hydraulic engineering and can be used as a water intake for thermal and nuclear power plants.

A known barrier to combating the proliferation of petroleum products 1,

The disadvantage of this device is the mixing of water in depth, which is undesirable for water intakes of GRES;

Known deep water intake, including a cleaning wall, visor, floats, ballast, retaining cables 2.

A disadvantage of this device is the considerable dynamic loads on the retaining wall.

The purpose of the invention is to reduce the dynamic loads on the retaining wall by stabilizing its position by circulation currents.

The goal is achieved by the fact that the water intake is provided with perforated pneumatic tubing placed horizontally between the visor and the floats on both sides of the collecting wall, and the floats are made in the form of a series of vertical cavities fixed to each other and open at the bottom.

FIG. 1 shows a deep water intake, cross section; in fig. 2 - the same, front view.

The structure contains floats 1, a retaining wall 9 of elastic waterproof material, perforated pipes 3, a visor 4, weights 5, retaining cables 6, ballast 7.

The device works as follows.

When air is supplied to the perforated lines 3, an air / air mixture is formed, which rises to the top.

the floats 1 are filled with air and the water intake structure is installed in a vertical (working) position. After the floats are filled, the air and the surrounding masses of water entrained by it reach the surface, forming a breaker, from which the water spreads to the sides, forming closed circulation currents. Moreover, the circulation zone is located above the visor. Those currents that are directed from the water intake assembly, extinguish dynamic loads on the collecting wall. Leaks directed toward the collecting wall are located in the lower part of the upper warm layer and coincide with the direction of flow of cold water, which can be taken from the lower layer of the reservoir, which favors the separation of flows with different temperatures. The visor 4, which is the upper edge of the water inlet, prevents water from being drawn from the bottom cold layer.

0 To stabilize the vertical position of the collecting wall, cargo 5 is suspended from the visor.

The water intake facility at a given location of the reservoir is secured with the help of bracing cables 6 and ballast 7.

In the event of a wave on the pond, due to the elasticity of the floats, partial damping of the waves occurs.

Since the upper part of the floats is always above the water horizon, there is no overlap of water in the water area of the intake bucket.

The use of the invention makes it possible to reduce the dynamic loads on the retaining wall by stabilizing its position by circulation currents.
