Abstract

The invention discloses an underwater dredging vehicle and a method for detecting the distance from the bottom of the stirring and suction head thereof. The underwater dredging vehicle includes a body of the dredging vehicle, the upper surface of which is hinged to a lifting arm, and the other end of the lifting arm is hinged to a connecting section The other end of the connecting section is fixed to the swing arm, the other end of the swing arm is fixed to the folding arm, and the other end of the folding arm is connected to the suction head. The other end of the lifting cylinder is hinged to the connecting seat of the lifting cylinder, the other end of the connecting seat of the lifting cylinder is fixedly connected to the lifting arm, the mounting seat of the swing arm cylinder is fixed on the lifting arm, and the mounting seat of the swing arm cylinder is hinged to the swing arm cylinder, the swing arm The other end of the oil cylinder is hinged to the connecting seat of the swing arm oil cylinder, and the other end of the connecting seat of the swing arm oil cylinder is fixedly connected to the swing arm. The underwater dredging vehicle can accurately measure the distance from the suction head to the bottom, so that the dredging thickness and dredging concentration are consistent with the actual working conditions.

Description

technical field [0001] The invention relates to the technical field of dredging, in particular to an underwater dredging vehicle and a method for detecting the distance from the bottom of a stirring suction head thereof. Background technique [0002] The vertical distance between the suction head of the underwater dredging vehicle and the surface of the bottom sediment plays a key role in the dredging thickness and dredging concentration. At present, the detection method of the vertical distance between the stirring suction head of the underwater dredging vehicle and the surface layer of the bottom sediment is mainly to measure the vertical distance of several groups of stirring suction heads from the bottom of the vehicle on land as an estimated value, and the dredging vehicle is not used in the vertical distance. Taking into account the subsidence of different sediments at the bottom of the water, the dredging thickness and dredging concentration are quite different from t...
