DEVICE FOR RESERVOIR AERATION Russian patent published in 2023 - IPC E02B15/02 C02F7/00 

FIELD: aeration equipment.

SUBSTANCE: device for reservoir aeration is proposed. The invention can operate in summer for enrichment of lower water layers by their mixing and in winter for creation of an ice-free glade to prevent the formation of oxygen deficiency for inhabiting ichthyofauna. The device for reservoir aeration includes platform 6 with supports in the form of floats 7, anchor 8, screw pump 5, in case 4 of which water-outlet windows 11 and screw water-lifting shaft 3 are located, wind drive 1 with vertical rotor 2 connected by a coupling to screw water-lifting shaft 3, corrugation pipe 12 with filter cup 13. In case 4 of pump 5, between its end and corrugation pipe 12 with filter cup 13, nozzle 14 is installed, an inner diameter of which is more than an inner diameter of case 4. Screw water-lifting shaft 3 of pump 5 is made with a different diameter of turns 10, wherein turns of a greater diameter of the screw are placed in nozzle 14, and turns of a smaller diameter are placed in case 4 of pump 5.

EFFECT: invention allows for an increase in a speed of lifting of warm water of a near-bottom layer to its upper layer and reduction in its heat losses, which is achieved with almost all the same overall and weight characteristics by increase in a speed of passage of a water column along an upper part of a pump case; efficiency of the operation of a device is also achieved due to its installation in a non-frozen water period, when it is easier to determine a place of installation and easier to deliver the device to this place, so the device is not required to fix to the bottom with supports, so just an anchor is lowered.
