Background
The trash rack can prevent floaters such as floating wood, branches, leaves, weeds, garbage, floating ice and the like from entering the water inlet along with water flow, and meanwhile, the water inlet is not blocked by the dirt, so that the water inlet capacity is affected. The main trash equipment is a trash rack at a water inlet. Many floaters in river flood period are increased rapidly, and the trash rack at the water inlet is easy to be blocked. If the trash is not removed timely, the hydropower station or the pump station can be forced to reduce the output and even stop, and the situation that the trash rack at the water inlet is crushed often occurs. In order to relieve the pressure on the trash rack at the water inlet, a channel trash rack is usually additionally arranged in a position, which is a few tens of meters away from the water inlet. A large pump station or a hydropower station is required to be provided with a sewage disposal working bridge, and a sewage disposal machine is used for cleaning the channel sewage disposal grating. The small and medium pump station or the hydropower station is generally not provided with a sewage disposal device, manual sewage disposal is needed, and the traditional sewage disposal grating is difficult to clean, dangerous and large in workload because a channel is not easy to put forward. In addition, the middle and small pump stations or hydropower stations in vast rural areas mainly adopt waterweed and side slope rolling stones as dirt in front of the grating, the waterweed floats on the water surface to mainly block the upper trash rack, and finer trash rack is needed; the barren rock mainly sinks to the bottom of the canal, and the requirement can be met without too fine grid spacing. Meanwhile, the traditional trash rack directly cuts off channels, blocks the passage of organisms in the river channel, and has a certain influence on the original ecological system of the river channel.
CN207828914U discloses an intelligent stepping rotary grading trash rack, which can clean up sundries in water by a vertical horse, but requires an external power supply, and meanwhile, the angle of a flexible trash rack and a trash rack cannot be changed, so that a certain limitation exists in sundries collection. And the height of the whole trash rack cannot be changed according to the water quantity change.
