WATER CLEANING DEVICE Russian patent published in 2006 - IPC E02B9/04 

FIELD: hydraulic structures, particularly for automatic cleaning of water exploited from opened water pools of rubbish and filamentous alga.

SUBSTANCE: device comprises cylindrical drum with perforated shell. The cylindrical drum is linked to inlet pipe of pump and is arranged in water intake chamber so that the drum may be rotated by drive. The device also has rubbish removal means made as spring-loaded cutter. The cutter has blade cooperating with the shell. The device also has rubbish removal means and perforated flushing pipeline. The cylindrical drum with perforated shell is partly submersed in water intake chamber and arranged on inlet pipe across water flow so that the drum may rotate around the inlet pipe by means of drive operated by control unit of the device. Perforated drum shell is provided with concave non-perforated surface, which defines rubbish removal tray installed along longitudinal axis of filter. Perforated flushing pipeline arranged in the drum has jet-forming flutes, which create flushing water cone from inner side of perforated shell in front of cutter, which is located on perforated shell part not submersed in water intake chamber. Perforated flushing pipeline is hydraulically communicated with pressure pipeline by means of hydraulic line arranged in inlet pipe. The hydraulic line passes into the inlet pipe on ground surface and projects from the inlet pipeline inside cylindrical drum chamber. Washing-out perforated pipeline with jet-forming flutes is arranged on outer side of cylindrical drum. The jet-forming flutes of the washing-out pipeline create flushing stream to wash away rubbish from rubbish removal tray. Flushing and washing-out pipelines are provided with pipeline operation control sensors. Flushing pipeline sensor is linked to water level sensor, which determines water level in water intake chamber and in cylindrical drum and operates cylindrical drum drive through control unit. Washing-out pipeline sensor is connected to position sensor of cylindrical drum through the control unit. The position sensor is made as magnetically operated sealed switch installed in inlet pipe and cooperating with magnet secured to rubbish removal tray end facing inlet pipe. The inlet pipe is provided with water intake bell. Time relay is included in magnetically operated sealed switch and control unit circuit.

EFFECT: increased efficiency and reduced costs of water cleaning.
