As shown in fig. 14, when the closing is completed, the end face 4.1 of the sector gear 4 contacts the second end face 5.5 of the barrier strip 5b under the action of the volute spring 6, the motor 10 is reversely rotated by a reset signal given to the motor 10 by the control module, the driving wheel 8 pushes the sector gear 4 to rotate counterclockwise, so that the energy storage member 5 is pushed to rotate counterclockwise, the energy storage type transmission mechanism is reset to the initial state, and the energy storage member 5 is limited again by the limiting member 7. As shown in fig. 15, when the mechanism is in the initial state, under the control of the reset signal, the motor 10 rotates reversely to drive the sector gear 4 to rotate counterclockwise, the boss 4.5 pushes the reset lever 9 to rotate, and thus the arc-shaped end 9.1 pushes the controlled device 104 to open and reset through the linkage shaft.

Further, this application embodiment still provides an intelligent circuit breaker, includes: the controlled device 104 and the energy storage type transmission mechanism connected to the controlled device 104 control the controlled device 104 to be switched on or switched off by the operation of the energy storage type transmission mechanism.

The energy storage type transmission mechanism drives the connecting rod 3 to move through the movement of the energy storage assembly 101 and the energy storage elastic element 102 so as to control the controlled device 104 to be switched on; after the switch-on, the control module gives a reset signal to the motor 10 to enable the motor 10 to rotate reversely, and the boss 4.5 of the sector gear 4 enables the reset lever 9 to rotate to drive the controlled device 104 to switch off.

The intelligent circuit breaker comprises the same structure and beneficial effects as the energy storage type transmission mechanism in the embodiment. The structure and advantages of the energy storage type transmission mechanism have been described in detail in the foregoing embodiments, and are not described in detail herein.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art.
