In figure: maintenance well lid 1, magnetic base 2, magnetic switch 3, upright fence post 4, be linked with coupling bar 5, be linked with 6, electromotor
Sleeve 401, polished rod 402, upper end 403 are fixed in large cover 7, the magnetic line of force 8, Magnet 301, non-magnetizer 302, vertical rod.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
Seeing Fig. 1-3, a kind of belt with switchable magnetic base is stretched fence, and it includes magnetic base 2, described magnetic force
Base 2 is fixed on electromotor large cover 7, and described magnetic base 2 is installed with upright fence post 4, and described upright fence post 4 leans on
The position of nearly magnetic base 2 is provided with magnetic switch 3, and the top of described upright fence post 4 is provided with and is linked with coupling bar 5, described extension
Connect on band coupling bar 5 and be linked with 6, described in be linked with 6 the top of many upright fence posts 4 linked together, form guard circle, institute
State guard circle internal for maintenance well lid 1.
Further, described magnetic switch 3 includes Magnet 301, and Magnet 301 is stood by the rotating fence that is arranged on of rotating shaft
The inside of post 4, the other end of described rotating shaft is provided with rotary handle, can be rotated by band moving magnet 301 by rotary handle, changes
Its " N " pole and the position of " S " pole.
Further, described upright fence post 4 includes that sleeve 401 is fixed in vertical rod, and described vertical rod is fixed on sleeve 401 rotatable
Magnetic switch 3 is installed, fix that in vertical rod polished rod 402 being installed on sleeve 401, be fixed with upper end at the top of polished rod 402
403.
Further, described magnetic switch 3 also includes that non-magnetizer 302, described non-magnetizer 302 are vertically fixedly mounted on
Upright fence post 4 is internal, it is possible to magnetic field produced by isolation Magnet 301.
Further, described magnetic base 2 uses permeability magnetic material to make.The magnetic line of force 8 shape is facilitated with permeability magnetic material by this
Become the loop of Guan Bi, and then produce magneticaction, magnetic base 2 is fixedly linked with electromotor large cover 7.
Further, described non-magnetizer 302 uses copper sheet material to make.Owing to therefore copper coin not magnetic conduction has every magnetic
Effect, it is possible to block magnetic induction line.
Operation principle of the present utility model is:
Magnetic base 2 shell is two lobe magnetic conductors, and centre separates with non-magnetic copper coin.Inside have one rotatable
Magnet, this Magnet is diametrically N, S pole.When Magnet rotates to centre position, magnetic line of force shape in two lobe magnetic conductors respectively
When becoming closed circuit, base magnetic force disappears, and fence can move easily；
After 90-degree rotation, N, S pole is respectively toward to two lobe magnetic conductors, now arrives another to Metal ground from N pole to magnetic conductor
Block magnetic conductor, to S pole, forms magnetic line of force Guan Bi, can be attached to firmly on Metal ground.Schematic diagram is shown in Fig. 3.
Have only to rotate magnetic switch 3 when needs are mobile and can produce magneticaction.
