Abstract

Use: oxygenation of water in water bodies, in particular, used for fish breeding. SUMMARY OF THE INVENTION: To provide air accumulation during the warm season and thereby increase the efficiency during cold time, the device comprises a pontoon for storing the air supply and a spool valve providing alternate air supply from the wind turbine with the compressor to the pontoon and to the duct. A synchronous valve is installed on the duct, and the distributor communicates with the pontoon via a pneumatic control system. The lower part of the duct is perforated. The holes are arranged in annular rows and each row is covered with a cover of elastic material. 1 il.

Description

The invention relates to devices for saturating water with oxygen, in particular, aquifers.

The famous reservoir aerator containing a propeller, a pump with a nozzle and a curved duct with an annular gap.

The aerator of water in fish-breeding reservoirs is also known. It contains a wind engine, a compressor and an air duct with a perforated cover made of elastic material in the underwater part, and a visual controller for its functioning is installed in the surface part.

A disadvantage of the known devices is that the air is supplied to the water only when there is wind. With increasing frost, when the ice shell becomes more compacted and there is a greater likelihood of asphyxiation, the wind subsides and the device for aerating the water in the reservoirs ceases to function.

The aim of the invention is to provide air accumulation during the warm period.

years and thereby increasing the efficiency of the device in the winter.

The goal is achieved by the fact that a device for aerating water in reservoirs is equipped with a pontoon for storing air, a spool valve for alternating air supply from the compressor to the pontoon and air duct and mounted on the last bellows valve, the distributor communicating with the pontoon by means of a pneumatic control system, the perforation is made in the form of annular rows of holes arranged in series with respect to the height of the lower part of the duct, and the cover is formed from separate sections for digging each row of holes.

The drawing shows a diagram of the described device.

The device contains a wind engine with compressor 1, a spool valve 2 with a spring 3 return and pneumatic control 4, the camera

pontoon 5, bellows valve 6, air duct 7 with perforation holes around the circumference, covered with rings of elastic material 8, and measles 9 pontoon.

The device works as follows.

A device for aerating water is towed to a predetermined part of the reservoir and placed on measles. In the warm season, with the presence of wind, the compressor forces air to the distributor. The spool of the distributor 2 under the action of the spring 3 passes air into the chamber of the pontoon 5, where it accumulates. When the critical pressure exceeds the force of the spring 3, the pneumatic control piston 4, compressing the spring 3, displaces the spool 2 to another channel and air flows through the perforated part of the duct 7 into the reservoir.

When frost occurs (for example, -25 ° C) the bellows valve 6 opens, the pressure in the chamber of the pontoon 5 drops, the spring 3 moves the stopper 2 to the initial position and the air through the chamber of the pontoon 5 and the bellows valve 6 circulates through the perforated part of the duct 7 until warm. period As the ice rises, the perforation rings come into operation one by one from top to bottom.

The proposed design of the device for aeration of water in water bodies

fits into any body of water, which, with little or no human involvement, until complete wear automatically aerates water during the most critical periods of the year, and the concentrated air supply during the winter period significantly exceeds the efficiency of aerators of this type.
