Drainage pump station forebay filtering device for irrigation

Abstract

The invention discloses a drainage pump station forebay filtering device for irrigation, and belongs to the technical field of drainage pump station forebay filtering devices for irrigation. The device comprises a filter box, a rotating shaft is rotatably connected to the middle of the top of the filter box, the front end of the rotating shaft penetrates through the filter box and is fixedly connected with a first driving mechanism, four filter plates are distributed on the circumference of the rotating shaft at equal intervals, and a cutting groove is formed in the position, between filter holes, of the top of each filter plate; the second driving mechanism drives the first scraper to automatically clean the filter plate, and the sea grass on the top of the filter plate is cut so that when the filter screen needs to be cleaned, manual operation is not needed, the irrigation water filter screen is automatically cleaned, time and labor are saved, easy-to-wind impurities such as the seagrass on the filter screen can be removed at a time, and the filtering efficiency of irrigation water is improved.

Description

technical field [0001] The invention relates to the field of a forebay filter device for a drainage pumping station for irrigation, in particular to a forebay filtering device for a drainage pumping station for irrigation. Background technique [0002] The pumping station is a device that can provide hydraulic power and pneumatic power with a certain pressure and flow rate. The pumping station project is the general name of the water inlet, water outlet, pump room and other buildings of the drainage and irrigation pumping station. In the pumping station project, the front pool of the pumping station Its function is to connect the diversion channel and the inlet pool, and its function is to connect the diversion channel and the inlet pool reasonably, so that the water flow can flow into the inlet pool smoothly and evenly, and provide good water absorption conditions for the pump.
