Amphibious bionic variable magnetism sucker

Abstract

The invention relates to an amphibious bionic variable magnetism sucker, comprising a driving system, a magnetic adhesion system arranged on the bottom part of the driving system, a static sealing system and a dynamic sealing system arranged between the driving system and the magnetic adhesion system, wherein a reducer output shaft is connected with a screw bush sheathed with a dynamic sealing cover; an SPGO and a felt are clamped between the dynamic sealing cover and the screw bush; a nut cover is connected on the screw bush and is provided with a magnetic sucker consisting of an N pole of a disk and an S pole of the disk; a reducer is connected with the static sealing cover; the static sealing cover and the dynamic sealing cover are linked with a sealing box of the driving system; and a sealing ring with an O-shaped upper part is clamped between the static sealing cover and the head part of the sealing box of the driving system, and a sealing ring with an O-shaped lower part is clamped between the static sealing cover and the dynastic covering cover. The sucker can be adjusted in a certain range of magnetic attraction force, adapts to complex and changeable amphibious conditions, serves as an adhesion device of a robot travelling on underwater / water magnetic structures, and serves as a carrier for miniature weapons.

Description

technical field [0001] The invention relates to an amphibious bionic variable magnetic sucker which can not only be used as an adsorption device for a walking robot on the wall surface of a magnetic structure above or below water, but also can be used as a carrier of miniature weapons. Background technique [0002] Operations in underwater environments, such as cleaning, inspection, welding and painting, have traditionally been performed by divers. Divers operate in this underwater environment, which is labor-intensive and low-efficiency. At present, there is an urgent need for underwater special operation robots to replace divers for underwater operations. The underwater special operation robot is composed of a walking mechanism, an operating mechanism and a control system. The amphibious bionic variable magnetic chuck is a device of the underwater special operation robot's walking mechanism, and its performance directly affects the development of the underwater special o...

Mechanical Design and Manufacturing, 2006 (3): 1-3 pages), gives the Harbin Industry Zhao Jie, Gu Baifeng, Fan Jizhuang and Cai Hegao, several teachers from the university, in order to solve the contradiction between the adsorption and detachment of the permanent magnetic adsorption mechanism of the wall-climbing robot, based on the finite element analysis, optimized the design of the incomplete demagnetization mechanism. The internal balance magnetic pole incomplete degaussing mechanism The use of electromagnets for internal degaussing solves the problem of adjustable magnetic force, but there are still two problems: one is large size and heavy weight; the other is that it can only be used in dry environments
