High-pressure flow-jet-type underwater desilting device and desilting ship

Abstract

The invention relates to a high-pressure flow-jet-type underwater desilting device and a desilting ship. The desilting ship comprises a ship body, a high-pressure water pump, a sewage pump and the high-pressure flow-jet-type underwater desilting device are mounted on the ship body, and the high-pressure flow-jet-type underwater desilting device comprises a shell which is open downwards and used for being reversely buckled on a river bed. The shell is provided with an inner cavity for containing silt and mud, a silt flushing head connected with silt flushing equipment and a silt sucking head connected with sucking equipment are arranged in the shell, and a dragging structure connected with a dragging mechanism on the desilting ship is arranged on the shell. When the desilting ship is used for desilting, the underwater silt is flushed through the silt flushing head, the stirred silt is closed by the shell, the silt sucking head sucks the silt away, and thus the desilting purpose is achieved; and through the dragging mechanism, the underwater desilting device is dragged, and the underwater desilting device is dragged to a next work position to start desilting work along the river bed.The underwater desilting device on the desilting ship can travel on the river bed and is high in adaptability on the complex river bed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection dredging, and in particular relates to a high-pressure jet underwater dredging device and a dredging ship. Background technique [0002] With the advancement of urbanization, the scale of cities continues to expand. The moats and urban rivers that used to be rippling in the past have gradually become sources of pollution. This not only affects the environment of the city, but also brings a lot of inconvenience to people's life. In addition, the accumulated silt and sludge have brought great problems to the city's flood and water drainage. Therefore, it has become an urgent task to focus on regulating the city's inland waterways, moats and drainage ditches, and eliminate the phenomenon of black and odor. [0003] At present, domestic dredging mainly uses excavators for sludge cleaning. First, the excavator is used to remove debris. The sludge is transported by pipeline or direct...

AI Technical Summary

Problems solved by technology

The river dredging ship can effectively remove underwater dirt, but the underwater dredging device on the river dredging ship has poor adaptability to complex river beds. For example, when the river bed fluctuates, the dredging efficiency of the underwater dredging device is low
