Sewage clearing device for water conservancy and hydropower

Abstract

The invention discloses a sewage clearing device for water conservancy and hydropower. The sewage clearing device comprises a shell, wherein bases are fixedly connected to the left side and the right side of the lower end of the shell, and anti-skid lines are arranged at the lower ends of the two bases; a through hole is formed in the lower side of the left end of the shell, and a sliding groove corresponding to the through hole is formed in the inner side of the right end of the shell; a sludge suction pump is fixedly arranged at the upper end of the shell, first connecting pipes are connected to the left end and the right end of the sludge suction pump, and rectangular filter cylinders are connected to the lower ends of the two first connecting pipes and comprise filter sleeves; and through grooves are formed in the outer sides of the filter sleeves at equal intervals, steel wire meshes are connected to inner cavities of the through grooves, conical blocks are connected to the outer sides of the filter sleeves at equal intervals, and the outer side of each conical block is connected with conical teeth. According to the sewage clearing device for water conservancy and hydropower, by arranging the sludge suction pump and the rectangular filter cylinders, sludge in water can be conveniently cleared, so that the situation that the flow of a flow channel is reduced due to excessive sludge accumulation is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower, in particular to a sewage cleaning device for water conservancy and hydropower. Background technique [0002] The trash racks installed at the water inlets of hydropower stations, water delivery systems, and water intakes of pump stations in water conservancy and hydropower projects are used to block water plants, driftwood and other sundries carried by the water flow, while the water inlets of hydropower stations, Trash racks installed in water delivery systems, water intakes of pump stations, etc. often have a large amount of dirt accumulation. Excessive accumulation of dirt can easily deform or collapse the trash rack, which in turn leads to shutdown of power stations and pump stations, seriously affecting the safe production and operation of the project . [0003] At present, the measures for cleaning the trash rack at the water inlet of the hydropower station and th...

Problems solved by technology

[0002] The trash racks installed at the water inlets of hydropower stations, water delivery systems, and water intakes of pump stations in water conservancy and hydropower projects are used to block water plants, driftwood and other sundries carried by the water flow, while the water inlets of hydropower stations, Trash racks installed in water delivery systems, water intakes of pump stations, etc. often have a large amount of dirt accumulation. Excessive accumulation of dirt can easily deform or collapse the trash rack, which in turn leads to shutdown of power stations and pump stations, seriously affecting the safe production and operation of the project

[0003] At present, the measures for cleaning the trash rack at the water inlet of the hydropower station and the water intake of the pumping station mainly adopt the methods of lifting the grid for cleaning, cleaning the pollution with the tooth rake, and cleaning the sewage with the sewage cleaning machine. The salvaged sewage still needs to be transported, placed and Buried, but there is no cleaning device that integrates the cleaning of sludge and the cleaning of rattan, aquatic plants and other dirt in the water
