Adsorption type underwater robot

Abstract

The invention provides an adsorption type underwater robot, and relates to the field of underwater robots. The adsorption type underwater robot comprises a machine body and a plurality of supporting legs movably installed on the machine body, a crawling driving mechanism and a water pump are installed in the machine body, and the crawling driving mechanism is in transmission connection with the supporting legs. Suction cups are arranged at the bottoms of the supporting legs, water pumping openings are formed in the suction cups, and water pumping pipelines are connected between the water pumping openings and the water pump. The machine body is further provided with a top drainage port, a top drainage pipeline is connected between the top drainage port and the water pump, and the top drainage port and the supporting legs are located on the opposite sides of the machine body respectively. According to the underwater robot, downward reverse thrust is generated on the robot body through upward drainage of the top drainage port, and the top drainage port is matched with the suction cups of the supporting legs to generate the suction effect, so that effective suction force is formed between the supporting legs and the water bottom, it is guaranteed that the whole underwater robot stably climbs or stays under the action of water flow, and the reliability of construction operation is improved.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to an adsorption underwater robot. Background technique [0002] The underwater robot is the key equipment for underwater unmanned operations. The adsorption underwater robot has a foot suction cup that can be reliably fixed on the bottom of the water, providing a stable support for underwater construction. [0003] For example, the Chinese invention patent with the authorized announcement number CN107054590B and the authorized announcement date of 2019.05.07 discloses a vibration-absorbing underwater quadruped wall-climbing robot, and specifically discloses that the wall-climbing robot includes a torso and two pairs respectively arranged on the torso. The mechanical legs on both sides of the head also include a control system for controlling the work of the mechanical legs. Each mechanical leg includes a leg assembly and a vibration absorption device arranged at the end o...
