A grid type dredging device for water conservancy projects

Abstract

The invention relates to a grid type dredging device for water conservancy projects, which includes a back board and a hanging board, an extension board is arranged on the top of the back board, a switch is installed on the back of the extension board, and the front cabin is rectangular Frame structure, a row of grids is welded in the frame, two bearing sleeves on the left and right run through the top of the extension plate, and the driving gear and the driven gear that rotate and mesh with each other are installed in the two bearing sleeves through the rotating shaft. In the end, the stones left by the silt washing will remain on the cutting plate inside the grid, and these impurities will increase. After a certain period of time, when the operator reaches the vicinity of the ditch, he only needs to shake the handwheel to make the cutting plate The material plate is lifted upwards from the deep water part, and finally it is limited to the top by the automatic pop-up limit mechanism, so that the operator can easily clean up the intercepted impurities, thus effectively solving the problem that the deep intercepted objects are not easy to clean question.

Description

technical field [0001] The invention relates to the technical field of dredging devices, in particular to a grid-type dredging device used in water conservancy projects. Background technique [0002] Hydraulic engineering is a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. Reservoir dams are common products after hydraulic engineering construction, which are used to store irrigation water. Used for flood control, but also for fish farming. [0003] Reservoir dams used for fish farming will add grids in the dam channel. One is to use the grid to intercept fish during the flood discharge process, and the other is to use the grid to block impurities such as silt to prevent these impurities from being discharged from the dam channel. The water flows out together and pollutes the external rivers. Therefore, the impurities intercepted by this grid will only have a large number o...

[0003] Reservoir dams used for fish farming will add grids in the dam channel. One is to use the grid to intercept fish during the flood discharge process, and the other is to use the grid to block impurities such as silt to prevent these impurities from being discharged from the dam channel. The water flows out together and pollutes the external rivers. Therefore, the impurities intercepted by this grid will only have a large number of tree branches. Although they are intercepted in the dam channel, in order to prevent them from covering the grid gap, they also They need to be salvaged, but because they are mostly located at the bottom of the water flow due to grid blocking, it is inconvenient to clean, so it is necessary to design a desilting device for this occasion to meet the cleaning requirements
