DEVICE FOR WATER INTAKE FROM SURFACE SOURCES Russian patent published in 2020 - IPC E02B9/04 E03B3/04 

FIELD: water supply.

SUBSTANCE: invention relates to water abstraction from surface sources and can be used in recycling water supply systems of concentrating mills and mining industry located in areas with harsh climatic conditions. Proposed device comprises float floating platform furnished with rectangular closed tubular frame from below. Tubular frame consists of light metal hollow ends of hollow pipes 2. From above tubular frame 2 is equipped with fastening metal plate 4 above water edge. Under the bottom of the platform (pontoon), in the middle, swirler 8 is pumped through it to the area of water intake with a pumping device, rotation of swirler 8 creates whirlpool funnel 13 in water under a platform with pipes 2, which provides water intake from vortex funnel 13. Pipes 2 under pressure are filled with air through air intake branch pipes with a crane using a compressor (not shown). Submersible hollow shaft 6 with swirler 8 also includes suction pump 9, due to which water is supplied upwards into pipe, above platform 4, further to consumer. Into the platform (pontoon) bottom with pipes 2 intake head 10 is fixed with holes along the circumference of the rectangular frame consisting of pipes 2. Wave phenomena created by swirler 8 with blades 14 of hollow shaft 6, towards intake head 10 prevent sticking and accumulation on it of fibrous structures, garbage, algae, as well as sticking of young fish. Hollow shaft 6 with swirler 8 is immersed in water taking into account water freezing depth in water intake source. In case of water intake termination or need to replace hollow shaft 6 of vane 14 swirler 8 are folded and platform can also move to another section of water intake, the design of platform occupies floating position above water edge.

EFFECT: technical result is simplification of device design, increased efficiency of water extraction and reliability of intake head protection.
