Abstract

The invention relates to a tile type shielding device of cylindrical permanent magnets, which comprises a stander, wherein the stander is provided with a supporting component, the supporting component comprises a left half shaft, a hollow cylindrical magnetic core shaft and a right half shaft; the hollow cylindrical magnetic core shaft is provided with two coaxial and parallel cylindrical permanent magnets; the two cylindrical permanent magnets are externally provided with a rotatable shielding body; the rotatable shielding body comprises two tile-shaped shielding boards; the two tile-shaped shielding boards are covered on outer cylindrical surface magnetic poles of the cylindrical permanent magnets; and the tile-shaped shielding boards are rotatablely arranged with the left half shaft and the right half shaft by rotating a connecting disc. The tile type shielding device has the characteristic of uniform forcing since the cylindrical permanent magnets are externally provided with the rotatable shielding body, can achieve the aim of changing the magnetic field intensity of different areas only by inputting smaller power through a power input wheel, and can from into a magnetic loop between the two tile-shaped shielding boards and the hollow cylindrical magnetic core shaft due to the design of the hollow cylindrical magnetic core shaft.

Description

technical field [0001] The invention relates to a tile-type shielding device for a cylindrical permanent magnet, in particular to a shielding device equipped with a cylindrical permanent magnet, a hollow cylindrical magnetic-conducting mandrel and a rotating shield. There are two cylindrical permanent magnets coaxially arranged on the shaft, and a rotating shield is arranged outside the two cylindrical permanent magnets; the rotation of the rotating shield can be realized to achieve the purpose of changing the magnetic field strength in different regions; 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 ...
