DEVICE TO PROVIDE AUTOMATIC WATER CLEANING OF RUBBISH AND ALGAE Russian patent published in 2007 - IPC E02B15/00 

FIELD: hydraulic equipment, particularly adapted to suck water from water pools and supply pipelines for irrigation and industrial purposes.

SUBSTANCE: device comprises compressed air source connected with perforated high-pressure and low-pressure pipelines provided with air valve-type channels. The channels are located on bottom and slopes of supply channels, are inclined at 45-60° with respect to water flow and are secured to support members. The channels are connected with each other by means of flexible pipeline through nipples and linked to compressor through flow-reversing tank. The flow-reversing tank has pressure sensor, which determines lower and upper compressor control limit pressure, as well as lower and high pressure sensors. Control elements of pressure sensors are connected to perforated pipelines at ends thereof and are interconnected with hydraulic drives cooperating with executive members located in front parts of perforated pipelines. Device also has fender inclined with respect to flow direction and connected to supply channel berm by the first end. The second fender end is fastened to berm of bypass channel communicated to rubbish collecting means. Bypass channel is made in lower pool and is isolated from supply channels by means of partition structure provided with flat gate with electric drive and submersed in lower pool in vertical direction. Sensor is arranged in front of flat gate and is made as hollow sealed pipe partly immersed in water. The hollow sealed pipe is installed on pin and provided with wings arranged from both sides of flat gate. The wings are made as trays secured to lower pipe end and immersed in water. Control-rod is installed on one wing of control sensor so that the control-rod is hinged to wind end and cooperates with double-contact switch included in circuit of control unit of flat gate made in electric drive and fastened to partition structure. Two end switches cooperating with upper and lower flat gate position limiters are included in double-contact switch circuit. The limiters are connected to upper flat gate part.

EFFECT: increased efficiency of water intake pump station cleaning.
