The utility model aims at economic development and market demand, provide a permanent magnetism actuating mechanism that simple structure, reliability are high.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a permanent magnet driving mechanism is characterized by comprising an operating rod, a buffer spring, a brake separating limit, an iron core, a magnetic conduction ring, permanent magnet steel, a coil A, a coil B, a permanent magnet upper end cover, a permanent magnet lower end cover, an operating rod guide part, an upper clamping plate, a lower clamping plate and a shell; the utility model discloses a magnetic control device, including operating rod, buffer spring, operating rod, coil A, coil B, magnetic conductive ring, permanent magnet steel magnet, coil A, coil B, magnetic conductive ring, permanent magnet lower end cover, coil B's lower side, coil A, coil B's lower side is located the iron core with coil B's downside.

According to the utility model discloses an optimal embodiment, during the separating brake, coil A with coil B has got electric, the iron core with the permanent magnet upper end cover produces the repulsion, the iron core with permanent magnet lower end cover produces suction, the iron core moves down to permanent magnet lower end cover and rather than in close contact with, the iron core moves down and drives the spacing action of separating brake, and then drives the manipulation pole moves down and carries out the separating brake.

According to the utility model discloses an optimal embodiment, during the combined floodgate, coil A with coil B is the electricity respectively to polarity is opposite when with the disconnection, the iron core with permanent magnet upper end cover produces suction, the iron core with permanent magnet lower end cover produces the repulsion, the iron core shifts up to permanent magnet upper end cover and rather than in close contact with, when the iron core shifts up, the compression buffer spring, buffer spring promotes the operation pole shifts up and closes the floodgate.

The beneficial effects of the utility model are that adopt coil A and coil B to get electricity and carry out the permanent magnetism drive, adopt opposite polarity's power to carry out the divide-shut brake, existing gravitation also has the repulsion simultaneously, makes divide-shut brake speed faster, and actuating mechanism's reliability is also higher simultaneously.
