Magnetic absorption device

Abstract

The invention relates to a magnetic absorption device which is characterized by comprising a cylindrical permanent magnet, left yoke iron, right yoke iron, an upper magnetism isolating block, a lower magnetism isolating block and an actuator. The cylindrical permanent magnet is rotationally arranged in a hollow barrel enclosed by the left yoke iron, the right yoke iron, the upper magnetism isolating block and the lower magnetism isolating block, a rear cover plate is connected to an end of the hollow barrel in a fastened manner, and an output end of the actuator is connected with the cylindrical permanent magnet by a coupling; the actuator can be in a 0-degree angle state and a 90-degree angle state, and the magnetic absorption device is in a magnetization state when the actuator is in the 0-degree angle state; the magnetic absorption device is in a demagnetization state when the actuator is in the 90-degree angle state; a Bluetooth communication module is arranged on a control panel of the actuator. The magnetic absorption device has the advantage that the magnetic absorption device can be in the magnetization state or the demagnetization state under the remote control of external control units.

Description

technical field [0001] The invention relates to a magnetic adsorption device, which belongs to the technical field of special robots. Background technique [0002] The wall-climbing robot facing the wall of the guide magnet is an important category of special robots, which can be widely used in the operation and maintenance of nuclear energy, shipbuilding, chemical industry, wind power and other industries. The magnetic adsorption device is an important unit component of this type of wall-climbing robot. Traditional adsorption methods include permanent magnetic adsorption, electromagnetic adsorption, and permanent magnetic adsorption with adjustable magnetic poles. The permanent magnetic adsorption method has a strong suction force, which is safe and reliable, but the magnetic force cannot be adjusted, which makes it difficult to climb the wall and easily damage the wall surface; the electromagnetic adsorption method has a large suction force and the magnetic force is adjus...

AI Technical Summary

Problems solved by technology

This method of mechanically regulating the magnetic poles is simple and does not consume power at all, but it has the following disadvantages: the magnetic pole regulating device needs to be fixedly installed on the frame of the wall-climbing robot, and can only be adjusted when the permanent magnetic adsorption device passes through the regulating device. The magnetic pole of the unit, but for the adsorption unit far away from the control device, it does not have the ability to adjust the magnetic pole

Therefore, the wall-climbing robot using the above-mentioned mechanical pole-adjusting adsorption unit has a persistent adsorption force at the bottom and cannot be eliminated, so this type of wall-climbing robot has the important disadvantage of being unable to turn
