Propelling device for underwater robot

Abstract

The invention discloses a propelling device for an underwater robot, and mainly relates to the field of underwater robots. The device comprises a mounting cylinder, a motor is arranged on the side, away from the mounting cylinder, of a fixing plate, an output shaft of the motor is located in the mounting cylinder and connected with a first electric push rod, a plurality of connecting rods are rotationally arranged on the cylinder wall of the mounting cylinder and penetrate through the cylinder wall of the mounting cylinder, and paddle plates are arranged at the ends, located outside the mounting cylinder, of the connecting rods; a first bevel gear is arranged at the end, located in the mounting cylinder, of the connecting rod, and the movable part of the first electric push rod is sleeved with a second bevel gear capable of being meshed with the first bevel gear. The propelling device has the beneficial effects that the water stirring force of the whole propeller can be adjusted by adjusting the angle of the propeller plate, so that the propelling speed of the underwater robot is adjusted, the propelling speed does not need to be adjusted by frequently adjusting the rotating speed of the motor, the working intensity of the motor is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to a propulsion device for underwater robots. Background technique [0002] The underwater robot, also known as the unmanned remote control submersible, is a kind of extreme operation robot that works underwater. The underwater environment is harsh and dangerous, and people's diving depth is limited, so underwater robots have become an important tool for developing the ocean. A typical remote-controlled submersible consists of surface equipment (including control consoles, cable winches, hoisting equipment, power supply systems, etc.) and underwater equipment (including repeaters and submersible bodies). The main body of the submersible moves by propellers underwater, and the main body is equipped with observation equipment (video camera, camera, lighting, etc.) and operating equipment (manipulators, cutters, cleaners, etc.). [0003] The underwater propulsion device is the power ...

AI Technical Summary

Problems solved by technology

Most of the common propulsion devices use the motor to drive the propeller to drive the underwater robot. When the speed of the underwater robot needs to be changed, the speed of the propeller can only be changed by changing the speed of the motor, so as to realize the speed of the underwater robot. However, the frequent conversion of the motor speed will accelerate the wear and aging of the motor components, which will increase the failure rate and reduce the service life of the motor, which will affect the normal work and use of the underwater robot.
