FIELD OF THE INVENTION The invention relates to the fishing industry, in particular to devices for coating ponds.

The purpose of the invention is to reduce wind loads, reducing the complexity of manufacturing, installation on the pond and operating costs.

The use of the proposed device allows to ensure conditions for the normal development of aquatic organisms, including larvae and fry of fish, for which a certain concentration of oxygen in water and illumination of sunlight are necessary.

The drawing schematically shows the proposed device.

The device for covering water bodies consists of dome-shaped elements 1, made of a flexible transparent material, capable of acquiring a predetermined dome shape under the influence of forced air. Dome-shaped elements 1 along the perimeter have a load 2, which is a plastic bag filled with water. Dome-shaped elements 1 are interconnected by nozzles 3 for sequential transfer of air from the cavity of one element 1 into the cavity of another.

The air supply system includes a pump 4 with a drive 5 and a control unit 6, an air pipe 7 connected to one of the dome-shaped elements 1, a pipe 8 for exhausting excess air, at the end of which a container 9 of elastic material is fixed, into which excess air enters . The rod 10 is mounted on the container 9 and serves to interact with the contacts of the control unit 6 when the container 9 is moved.

The buoyancy of the nozzles 3 is ensured by two floats 11 fixed on the ends of the nozzle 3, and their position relative to the water surface is kept stable by a weight 12 fixed in the middle. The pump 4 is equipped with a check valve 13, which prevents the air 6 from exiting from the overpressure from the pipeline 8 to the atmosphere.

Making the coating in the form of a set of interconnected floating nozzles 3 of the dome-shaped elements 1 makes it possible to simplify their manufacture and installation on the pond. In addition, unification of the coverage is provided, according to

How many components of the coating do not depend on the size of the reservoir. Dome-shaped elements 1 have an insignificant height relative to the water surface and even more so relative to the surface of the banks of the reservoir, which significantly reduces wind loads on the coating and does not require additional measures of their attachment (such as stretching, anchoring devices) or strengthening the rigidity of the structure. The rigidity of the structure and the stability of the dome-shaped elements 1 are provided with redundant

5 pressure under the dome of the elements 1 and cargo 2 filled with water, which greatly simplifies the design of the elements 1 and reduces the cost of their manufacture and installation. The introduction of control of the operation of the pump 4 for air pressure in the pipeline 8 for exhausting excess air can significantly reduce the operating costs of maintaining excess pressure in the dome-shaped elements 1 of the floor, in particular, reduce electricity consumption and maintenance costs.

An example of a polyethylene film provides sunlight exposure, which is necessary for the normal development of aquatic organisms.

In general, the device allows to increase the temperature of water in water bodies through the use of solar energy and increase the period of fish farming, the viability of young fish and, accordingly, the efficiency of fish farms.

The device works as follows.

Dome-shaped elements 1 are placed on the pond. At the time of placement, their plastic bags acting as cargo 2 are filled with water. Turn on the air supply system. The pump 4 injects air through the air pipe 7 into one of the dome-shaped elements 1, which acquires a predetermined dome-like shape. The excess air pressure under this dome-shaped element 1 is transmitted through the pipes 3 to the floating elements 1 in a row and through them successively to all the others covering the surface of the whole reservoir.

Excess air pressure is transmitted through pipe 8 to tank 9 of elastic material, under the action of which the shell of tank 9 rises up and moves rod 10. When a predetermined level is reached, rod 10 acts on the contacts of control unit 6, the operation of which causes shutdown of pump 5 Thus, the air injection by the pump 4 in the pipeline 8 is stopped and the non-return valve 13 is closed, preventing the air from exiting from the overpressure from the pipeline 8 to the atmosphere.
