Further, solenoid is wound on a coil rack, and coil rack is fixed in housing, and coil rack is set on dynamic iron core.
Further, the stage casing of push rod is provided with the shaft shoulder and external screw thread, is provided with annular boss in the mesopore of dynamic iron core; When push rod and dynamic iron core assembly, the shaft shoulder and boss sidewall are supported mutually, and the external screw thread in push rod stage casing has been threaded nut, and the another side sidewall of nut and boss is supported mutually.
The utility model beneficial effect is compared with prior art:
(1) the utility model have employed a kind of brand-new operation principle and structure, all accessories are all around a push rod assembling, install simple, non-maintaining, parts are few, cost material benefit, during work, main motion parts only has one, and without the need to mechanical trip, locker, the source of trouble is few, have higher reliability, application widely.
(2) operating mechanism of the present utility model is only provided with permanent magnet at combined floodgate end, guarantees that electric switch remains at a single state of combined floodgate or separating brake, has stopped the hidden danger that electric switch half point narrows.

Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.
The concrete structure of the utility model embodiment as shown in Figure 1 to Figure 3.
The Monostable permanent magnetism operating mechanism of the present embodiment comprises housing 10, push rod 20, solenoid 30, permanent magnet 60, dynamic iron core 40 and static iron core 50.
Housing 10 comprises the protecgulum 12, main body 11 and the bonnet 13 that are mutually permanently connected.Push rod 20 runs through housing 10, and dynamic iron core 40, static iron core 50 and solenoid 30 are all located in housing 10.In housing 10, push rod 20 runs through dynamic iron core 40 and static iron core 50 successively.Static iron core 50 and permanent magnet 60 are all fixed on inside protecgulum 12.Particularly, permanent magnet 60 has 8 pieces, and permanent magnet 60 is uniformly distributed in the surrounding of static iron core 50 and fits with static iron core 50 outer wall.In the present embodiment, the external diameter of static iron core 50 is greater than the external diameter of dynamic iron core 40, and permanent magnet 60 is distributed in static iron core 50 around, and like this when dynamic iron core 40 contacts with static iron core 50, dynamic iron core 40 can not touch permanent magnet 60, and therefore permanent magnet 60 can not produce wearing and tearing.
In addition, dynamic iron core 40 excircle is evenly provided with three eddy current water conservancy diversion flutings 42.
In the present embodiment, solenoid 30 to be fixed in housing 10 and to be set on dynamic iron core 40.Particularly, solenoid 30 is wound on coil rack 31, and coil rack 31 is fixed in housing 10, and coil rack 31 is set on dynamic iron core 40.
Dynamic iron core 40 fixed cover is located on push rod 20.Particularly, the stage casing of push rod 20 is provided with the shaft shoulder 21 and external screw thread 22, is provided with annular boss 41 in the mesopore of dynamic iron core 40.When push rod 20 and dynamic iron core 40 assemble, the shaft shoulder 21 and boss 41 sidewall are supported mutually, and the external screw thread 22 in push rod 20 stage casing has been threaded nut 23, and nut 23 is supported mutually with the another side sidewall of boss 41.
During combined floodgate, solenoid 30 forward is energized, dynamic iron core 40 under the effect of magnetic attraction with static iron core 50 adhesive, the passive iron core 40 of push rod 20 drives and stretches out toward protecgulum 12 direction, and dynamic iron core 40 attracts each other with permanent magnet 60 simultaneously, strengthens confining force.
During separating brake, solenoid 30 is oppositely energized, and dynamic produces magnetic field repulsive force between iron core 40 and static iron core 50, and dynamic iron core 40 drives push rod 20 to stretch out toward bonnet 13 direction and realizes separating brake under the effect of magnetic field repulsive force and electric switch separating brake power.
