Be provided with permanent magnet and coil rack between termination and static iron core, permanent magnet below coil rack, coil rack it is upper
Portion is embedded inside the head of moved end, and coil is wound with outside coil rack；Head sealing cover, static iron core and moved end head are equipped with logical
Hole, universal driving shaft are fixedly connected through head sealing cover and the through hole of static iron core in the through hole of moved end head with moved end head.
In use, the controlling switch of universal driving shaft bottom connection breaker, when leading to negative current in coil, moved end head can be
The lower motion upwards of magnetic field force effect, reaches separating brake working condition position, when leading to forward current in coil, moved end head can be in magnetic field
Moved downwards in the presence of power, reach combined floodgate working condition position, the state of open position is with the separating brake energy-stored spring with periphery
Realize, combined floodgate working condition position keeps being realized by in-house permanent magnet.The magnetic line of force of permanent magnet is via quiet
Termination, moved end head, static iron core form loop, and realizing closed loop magnetic field makes mechanism keep "on" position position, it is not necessary to mechanical lock
Buckle device, it is not required that have maintenance electric current in coil.
Preferably, the periphery of described static side head sets spacing ring flat-plate, and the bottom of spacing ring flat-plate is fixedly connected with static side head,
The top of spacing ring flat-plate is wrapped in moved end head periphery.When moved end head moves upwards, spacing ring flat-plate can limit the stroke of moved end head,
Anti- stop end head position skew, influences normal work.
Preferably, described universal driving shaft bottom is provided with spacing pad, and below head sealing cover, anti-stop end head drives spacing pad
The upward hyperkinesia of universal driving shaft, mechanism is caused in itself to damage.
Preferably, described head sealing cover is aluminum.
Preferably, copper sheathing is provided between described static iron core bottom and universal driving shaft, from copper sheathing is when universal driving shaft moves up and down
To lubrication.
Possessed beneficial effect is the utility model compared with prior art：
The utility model is reasonable in design, because of the characteristic of permanent magnet, is coordinated using permanent magnet and mechanism, realized
Mechanism status is changed and kept, and eliminates the cumbersome structure of tradition machinery formula spring energy agency, mechanism parts are few, structure is simple
It is single, reliability height, life, non-maintaining, easy to operate and low power consumption control volume-diminished, it is adapted to long-time frequent operation.
