Description
Technical Field
The invention belongs to the technical field of water surface and underwater cleaning, and particularly relates to a cleaning machine with a cleaning guide groove.
Background
In hydraulic and hydroelectric engineering, particularly in hydropower stations, the trash rack serves as a first barrier for a water inlet of a generator set, and has the functions of mainly intercepting floating dirt in water and preventing floating objects from flowing into the generator set through the water inlet. If the trash rack floaters are piled up too much, once the trash rack is damaged, the floaters flow into the generator set through the pressure steel pipe, and major accidents can be caused.
The trash cleaning machine that domestic power station generally adopted at present mainly has two kinds of working methods, one kind is that the trash cleaning grab bucket of trash cleaning machine gets into the current trash cleaning guide slot before the trash rack, through oscilaltion and snatch the floater in the guide slot, then the grab bucket goes out the guide slot again and unloads the floater, this kind of mode, the effect of decontaminating is better, but the prerequisite must have the trash cleaning guide slot before the trash rack. The cleaning mode is mainly aimed at the hydropower stations newly built in recent years. The other working mode is that the trash cleaning guide groove is not arranged in front of the trash rack, the trash cleaning machine can lift up and down along the surface of the trash rack to capture the trash in front of the trash rack, however, the trash cleaning mode has great limitation, if the water flow speed in front of the trash rack is high, the trash cleaning grab bucket can be flushed by water to be attached to the surface of the trash rack after being discharged, and the trash can not be continuously captured downwards. Or the floaters are too much in front of the gate to cause the floaters to be squeezed too tightly, the trash cleaning grab bucket cannot be inserted into the floaters, and the floaters cannot be salvaged. If a fixed guide groove is additionally arranged in front of each hole of the trash rack, the structure is difficult to realize.
