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 Rotational shielding device for cylindrical permanent magnets to solve the above problems

Abstract

The invention relates to a rotary shielding device for a tubular permanent magnet, which comprises a frame. A central shaft is arranged on the frame, and is provided with a magnetic core tube; the tubular permanent magnet is arranged outside the magnetic core tube; a rotary shielding body is arranged outside the tubular permanent magnet; the rotary shielding body comprises two tile shielding plates axially symmetrically arranged and magnetic end plates arranged at two ends of the tile shielding plates; the magnetic end plates arranged at two ends of the tile shielding plates are respectively provided with a rotary connecting piece; the rotary shielding body is rotatably arranged on the central shaft through the rotary connecting piece; and the magnetic end plates are magnetically connected with the magnetic core cylinder. By adopting the design of the magnetic end plates, the rotary shielding body and the magnetic core tube form a magnetic circuit, and when the tile shielding plates rotate, the tile shielding plates continuously switch the shielding areas of two tubular permanent magnet magnetic fields, so that an induction generator generates induction current.

Description

technical field [0001] The invention relates to a rotating shielding device for a cylindrical permanent magnet, in particular to a shielding device equipped with a cylindrical permanent magnet, a magnetically permeable core and a rotating shield, and a cylindrical The permanent magnet is provided with a rotating shielding body outside the cylindrical permanent magnet; the rotating shielding body includes two tile-shaped shielding plates arranged in axisymmetric manner and magnetically conductive end plates installed at both ends of the tile-shaped shielding plate; The rotation of the rotating shield can be realized to achieve the purpose of changing the strength of the magnetic field in different regions.
