Abstract

The invention discloses an underwater desilting vehicle and a method for detecting the distance between a stirring suction head of the underwater desilting vehicle and the bottom. The underwater desilting vehicle comprises a desilting vehicle body, a lifting arm is hinged to the upper surface of the desilting vehicle body, a connecting segment is hinged to the other end of the lifting arm, a swingarm is fixedly connected to the other end of the connecting segment, a folding arm is fixedly connected to the other end of the swing arm, and the stirring suction head is connected to the other endof the folding arm. A lifting oil cylinder mounting seat is arranged on the upper surface of the desilting vehicle body, a lifting oil cylinder is hinged to the lifting oil cylinder mounting seat, a lifting oil cylinder connecting seat is hinged to the other end of the lifting oil cylinder, and the other end of the lifting oil cylinder connecting seat is fixedly connected with the lifting arm. A swing arm oil cylinder mounting seat is fixedly connected to the lifting arm, a swing arm oil cylinder is hinged to the swing arm oil cylinder mounting seat, the other end of the swing arm oil cylinderand a swing arm oil cylinder connecting seat is hinged, and the other end of the swing arm oil cylinder connecting seat is fixedly connected with the swing arm. A lifting oil cylinder disablement sensor, a swing arm oil cylinder disablement sensor and a sonar distance measuring meter are arranged on the desilting vehicle body. The underwater desilting vehicle can accurately measure the distance between the stirring suction head and the bottom, and the desilting thickness and the desilting concentration conform to actual work 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...
