A propeller hydraulic control system for an underwater robot

Abstract

The invention discloses a propeller hydraulic control system of an underwater robot, which comprises a casing, and a balance mechanism is installed inside the casing, and the balance mechanism includes a rotating groove, a rotating fin, a spoiler, a groove, an upper top plate, a lower The top plate, the transmission rod in the same direction, the first electric telescopic rod, the steering bar and the balance fin, and the rotation slots are symmetrically opened on one side of the housing. The balance mechanism of the present invention can facilitate the staff to maintain the balance and stability of the propeller when it moves, and also It can facilitate the staff to increase the movement resistance when the propeller stops, reduce the drift distance after the propeller stops moving, improve the balance and stability of the underwater robot, and avoid the propeller working when the staff is operating the underwater robot. When the balance is poor, it avoids that when the propeller stops, the underwater robot will continue to move due to the residual thrust, causing the underwater robot to drift, collide and be damaged, which will affect the work of the underwater robot.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to a propeller hydraulic control system of an underwater robot. Background technique [0002] Underwater robot, also known as unmanned remote control submersible, is a kind of extreme operation robot working underwater. The underwater environment is harsh and dangerous, and the depth of human diving is limited. Therefore, underwater robots have become an important tool for developing the ocean. There are mainly two types of submersibles: remote-controlled submersibles with cables and remote-controlled submersibles without cables. Among them, remote-controlled submersibles with cables are divided into three types: self-propelled underwater, towed and crawlable on seabed structures. When the robot moves in the water, it needs to use propellers as the moving power to carry out work; [0003] But the propeller of a kind of underwater robot on the market at present, the balanc...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a propeller hydraulic control system of an underwater robot, which can effectively solve the problems raised in the above-mentioned background technology. For a propeller of an underwater robot currently on the market, during the operation and use of the staff, the propeller The balance of the underwater robot is poor, and the underwater water flow is complex and changeable, which makes it difficult for the staff to control and inconvenient to use. At the same time, when the underwater robot needs to work or avoid, after the propeller stops, the robot will continue to move due to the residual thrust. If it is too long, it is easy to cause the underwater robot to drift and collide, causing damage to the propeller, which will affect the problem of the staff operating the underwater robot
