Self-adaptive trash holding device with variable grid distance and length

Abstract

The invention discloses a self-adaptive trash holding device with variable grid distance and length, belonging to the technical field of water environment engineering. The trash holding device comprises bottom slots, lower grids, upper girds, upper slots, a buoyancy tank, sliding shafts, sliding rings, waterproof sleeves, bolts, screw holes, arc insertion holes and through slots. The lower grids are fixed in the arc insertion holes of the bottom slots, vertical parts of the upper grids penetrate into the upper slots, inclination parts of the upper grids are inserted into the lower grids, the sliding rings are fixed in the centers of the bottom ends of the upper grids, one end of each sliding shaft is fixed in the center of interior of the bottom end of each lower grid, the sliding shafts penetrate through the sliding rings, the lower ends of the waterproof sleeves are connected and fixed at the bottom ends of the lower grids, the upper ends of the waterproof sleeves are connected and fixed at the bottom ends of the upper girds, and the buoyancy tank is fixed on the outer sides of the upper slots. According to the self-adaptive trash holding device, suspending pollutants are driven by water power to move upwards along the grids, so that the defect that a traditional trash holding grid is blocked by the pollutant is overcome.

Description

technical field [0001] The invention relates to a pollution-stopping device with self-adaptive variable grating bar spacing and length. It belongs to the technical field of water environment engineering. Background technique [0002] Most of the traditional trash racks used in rivers and channels in our country are fixed grid structures, which are composed of frames, transverse partitions and bars, which can intercept suspended solids in rivers and channels. The disadvantage of traditional trash racks is the removal of suspended solids. Traditional trash racks are usually fixed on both sides of the river bank, and the grid spacing is fixed. When the spacing is large, it is difficult to intercept small suspended solids. When the spacing is small, it is easy to block the trash rack. During the operation of the trash rack, the suspended matter is mostly suspended on the trash rack, which affects the appearance and is difficult to clean. In addition, there is also a trash rack...

Problems solved by technology

The disadvantage of traditional trash racks is the removal of suspended solids. Traditional trash racks are usually fixed on both sides of the river bank, and the grid spacing is fixed. When the spacing is large, it is difficult to intercept small suspended solids. When the spacing is small, it is easy to block the trash rack. During the operation of the trash rack, the suspended matter is mostly suspended on the trash rack, which affects the appearance and is difficult to clean

In addition, there is also a trash rack that uses an electric device to automatically clean up suspended matter, which can transfer the suspended matter to the trash bin using a conveyor belt or similar device, which solves the post-processing problem of the traditional trash rack. However, the electric trash rack Waste of energy and difficult to install and maintain
