The magnetic field interaction for the U-shaped formation of magnet 1 of induced field and first that first coil 7 is produced, and the displacement of permanent magnetic device is hindered,
Reach spacing purpose.
It is U-shaped to make the U-shaped magnet 1 of U-shaped iron block 6 and first be in just relative position in another specific embodiment
Multiple support columns 9 are provided between one end of iron block 6 and the second protector 8, make the bottom of the U-shaped protector 8 of iron block 6 and second
Portion is spaced apart, so that the U-shaped magnet 1 of U-shaped iron block 6 and first is in identical level height.It is understood that support
The height of post 9 is set according to the first U-shaped magnet 1 relative to the distance between Seismic Isolation of Isolation Layer bottom plate 15.
Shown in Figure 3 in another specific embodiment, support column 9 includes upper plate, lower shoe and positioned at upper
