DEVICE FOR AERATION OF WATER Russian patent published in 2018 - IPC A01K63/04 C02F7/00 

FIELD: fishing and fish breeding.

SUBSTANCE: invention relates to lake fishing and can be used to saturate the water with oxygen in order to save fish from freezing, and also to be used as a technical tool for fish concentration. Device contains a compressor, a rubber hose, a sprayer. Device is made in the form of a L-shaped pipe, one component part of which is located vertically in the water column, and the second one – horizontally. Vertical lower part of the pipe, located in the water column, is equipped with a intake pipe with a sampling head with holes and flexible brushes. Branch pipe is equipped with a shaft with an impeller in the form of a turbine to create a rotational pressure water flow along the entire height of a part of the vertical pipe. Horizontal part of the pipe is made by a diffuser. Impeller for supplying compressed air is connected with the air supply hose to the top of the diffuser. Branch pipe with the intake head, the vertical part of the pipe and the diffuser are made of wear-resistant polyethylene material.

EFFECT: ensuring effective enrichment of the water flow downstream of ice dissolved in the water by oxygen by activating the aeration process along the length of the lake or water body, and ensuring the possibility of wider usage of it.
