Problems solved by technology

This kind of magnetic shielding device has good shielding effect, simple structure and convenient manufacture, but this patent is limited by the overall structure and is only suitable for shielding the photomultiplier tube of strong magnetic field. Its function is single and cannot perform magnetic energy conversion; therefore, it is necessary to provide a Double-plate shielding device for ring-type permanent magnets to solve the above problems

Abstract

The invention relates to a double plate type shielding device for an annular permanent magnet. The double plate type shielding device is provided with a stand, wherein a central shaft is arranged on the stand, and the annular permanent magnet is installed on the central shaft. One plate type rotating shield is arranged on one magnetic pole end face of the annular permanent magnet, and another plate type rotating shield is arranged on the other magnetic pole end face of the annular permanent magnet. The two plate type rotating shields are connected into a whole through bridging ribs. The two plate type rotating shields are installed on the central shaft through rotating connectors, a cylindrical magnetic conducting wall is arranged outside the outer cylindrical surface of the annular permanent magnet, and the cylindrical magnetic conducting wall is installed on the stand. In the invention, and the purpose of changing the magnetic field intensity in different areas can be realized by adopting the design of respectively arranging one plate type rotating shield on both magnetic pole end faces of the annular permanent magnet; and the plate type rotating shields and the cylindrical magnetic conducting wall can form a magnetic conducting loop by adopting the design of arranging the cylindrical magnetic conducting wall outside the plate type rotating shields.

Description

technical field [0001] The invention relates to a double-plate type shielding device for an annular permanent magnet, in particular to a shielding device equipped with an annular permanent magnet, a cylindrical magnetic conduction wall and a plate-type rotating shielding body. The shielding device drives the plate-type rotating shielding body through a power input wheel For rotating motion, the double-plate shielding device of the ring-shaped permanent magnet can generate electric energy by utilizing the principle of rotating magnetic shielding. Background technique [0002] Patent No. ZL200610113824.5 discloses a magnetic shielding device with a multi-layer composite structure for shielding strong magnetic fields. It is characterized in that it adopts a multi-layer composite structure, including three layers from the outside to the inside: a silicon steel part, which is the middle layer ; an alloy component, which is the inner layer; a solenoid coil, which is the outer laye...
