In the brake separating process: the brake opening and closing conversion flywheel 1 is forced to rotate anticlockwise under the pressing action of a spring 805 on the second elastic component 13 when the U-shaped groove cannot clamp the interlocking shaft 18 at the upper left part of the brake opening and closing conversion flywheel 1, and meanwhile, the linkage plate 7 is forced to move upwards to force the brake opening and closing positioning plate to rotate clockwise; the switching-on and switching-off switching flywheel 1 continues to rotate anticlockwise until a connecting shaft on the switch main shaft 6 is hung in a U-shaped groove of the positioning switching-on and switching-off plate 2. The switching-on and switching-off of the flywheel 1, the switch main shaft 6 and the switch state are simultaneously maintained after the switching-off is finished.
4. Electric energy storage operation: through the driving effect of motor 9, energy storage flywheel 4 and axle clockwise movement, when rotatory arrival position, block the lock axle 18 of energy storage flywheel 4 by the draw-in groove of energy storage checkpost 5, represent that the energy storage targets in place, oppress energy storage auxiliary micro-gap switch 11 simultaneously, the micro-gap switch signal is normally opened by the normal close, cuts off motor 9 power, and the motor stops.
Through the design, the operating mechanism can complete a whole set of switching-on and switching-off operations, so that the switching-off operation of the switch is driven. The motor 9 and the matched auxiliary part are additionally arranged at the same time, so that the electric operation of the mechanism is completed, and the mechanism can be further linked with matched automatic equipment.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
