Technical Field
[0001] The utility model relates to the technical field of trash racks, in particular to a water conservancy river trash rack with a backwashing function. Background Art
[0002] Trash racks are usually installed in front of the water inlet. They are frame-type structures used to block aquatic plants, driftwood and other debris (generally referred to as trash) carried by the water flow.
[0003] At present, with the serious water pollution, in order to better treat the water quality, it is generally necessary to use a trash rack to intercept impurities. After the trash rack is used for a long time, it needs to be cleaned. For example, the fully automatic backwashing anti-clogging grille structure disclosed by the authorization announcement number CN214936123U is mainly composed of a flushing device and a driving component. The flushing device is located on one side of the grille plate and consists of a water tank, a water guide pipe and a high-pressure nozzle. The water flow is ejected by the nozzle after pressurization to backwash the grille plate. The driving component can drive the slide bar to move in the rectangular slide, thereby expanding the working range of the high-pressure nozzle and improving the cleaning effect of the blockage. However, the sleeve and its cross bar driven by the driving mechanism move, and a spring is also arranged inside the sleeve. Since the limit plate has a certain inclination angle, the spring will cause a large degree of extrusion or stretching in the actual movement of the cross bar, and even the distance that the cross bar actually moves is very limited, resulting in a greatly limited range of spraying. For this reason, we propose a water conservancy river trash rack with backwashing function. Utility Model Content
