Zero-leakage magnetic coupling suction type propeller for deepwater working condition ROV and propelling method

Abstract

The invention discloses a zero-leakage magnetic coupling suction type propeller for a deepwater working condition ROV and a propelling method. The device comprises a watertight connector, a gear motor, a driver, a magnetic coupling system and a disc propeller; the watertight connector is fixedly connected with the tail end of a machine body shell; the gear motor is connected with the watertight connector; the driver is connected with the gear motor and then installed in the machine body shell; the magnetic coupling system is connected with the gear motor; and the disc propeller is installed atthe top end of the machine body shell. The device can be used independently and can also be installed on a functional auxiliary device on an ROV and other underwater operation devices, the device isdriven by the internal gear motor, torque is transmitted to the magnetic coupling system and then transmitted to the special disc propeller through the magnetic coupling system, the disc propeller rotates, liquid is locally drained to form local vacuum, and therefore the industrial-grade special underwater equipment can be sucked on the surface of an object.

Technical field: [0001] The invention relates to a zero-leakage magnetic coupling adsorption thruster and a propulsion method for ROV in deep water working conditions. Background technique: [0002] At present, at home and abroad, it is used for underwater motion detection on the bottom, or inclined surface, or on the vertical wall, etc., completely relying on precise control of ROV's underwater movement to achieve the expected working position. This method puts forward very high requirements for the control system of ROV itself. In addition, the underwater working environment is greatly affected by factors such as water flow, and it is difficult to achieve precise control to achieve the state of adsorption on the bottom, inclined surface or even the vertical wall, which brings great challenges to the ROV fixing method of some operations.

AI Technical Summary

Problems solved by technology

[0002] At present, at home and abroad, it is used for underwater motion detection on the bottom, or inclined surface, or on the vertical wall, etc., completely relying on precise control of ROV's underwater movement to achieve the expected working position. This method puts forward very high requirements for the control system of ROV itself. In addition, the underwater working environment is greatly affected by factors such as water flow, and it is difficult to achieve precise control to achieve the state of adsorption on the bottom, inclined surface or even the vertical wall, which brings great challenges to the ROV fixing method of some operations. Difficulty and Challenge

[0003] When it is necessary to detect an underwater dam body, or a bridge pier, or an underwater environment with a certain angle, ROV needs to precisely control its movement and be able to be stably fixed at a certain position within a certain period of time, so that operators on the road can carefully Observations, traditional ROVs cannot achieve this function, which brings great difficulties and challenges to operations under such working conditions

[0004] The other part of the adsorption propeller is mostly an underwater dynamic sealing structure, which may cause leakage, which will cause unnecessary damage to the equipment, and also limit the depth of underwater operations
