4, crank arm mechanism 1 transfers to drive operation handle 36 towards right rotation so that the contact apparatus separating brake of breaker towards dextrorotation, and at the same time
Energy storage torsional spring 2 is tightened and makes 2 energy storage of energy storage torsional spring.
Lock process：Please refer to Fig.2, Fig. 6 and Fig. 7, when crank arm mechanism 1 is towards during right rotation, the connection of the right side of crank arm mechanism 1
Bayonet lock 3 is caught in the bayonet 11 for the fixture block 8 being connected in the second shaft 18, and promotes the right Access Division 10 of fixture block 8 towards right rotation, from
And make it that the bayonet of fixture block 8 is increasingly turned to towards right direction, the left Access Division 9 of fixture block 8 block bayonet lock 3 and prevent bayonet lock 3 from from
Deviate from bayonet 11；In 8 lower end of fixture block towards while right rotation, the upper end of fixture block 8 is towards anticlockwise, the claw 12 of 8 upper end of fixture block
Towards anticlockwise and enter the card slot 14 in first rotating shaft 13, claw 12 be against the bottom of card slot 14 and by 13 switch of first rotating shaft,
So that card slot 14 turns to direction downward so that claw 12 goes to the left side of first rotating shaft 13, when claw 12 goes to first rotating shaft 13
Left side after, the first reduction torsion spring 15 in first rotating shaft 13 reverses first rotating shaft 13 and resets and card slot 14 is turned to towards right
Direction, claw 12 cannot by card slot 14 and to right rotation, claw 12 is blocked by first rotating shaft 13 at this time, and fixture block 8 cannot rotate,
Bayonet lock 3 is stuck in the bayonet 11 of fixture block 8, and therefore, crank arm mechanism 1 can not be towards anticlockwise, and energy storage torsional spring 2 keeps tightening energy storage
State.This is lock process.
Dropout making process：Fig. 6 and Fig. 7 are refer to, electromagnet 17 moves downward and drives dropout connecting lever 16 to rotate, and threads off
Connecting lever 16 drives first rotating shaft 13 to rotate, so that the opening of card slot 14 is rotated to direction directed downwardly, claw 12 is able to dynamic card slot
Pass through and rotated to the right side of first rotating shaft 13 in 14, under the action of energy storage torsional spring 2, the lower end of fixture block 8 is towards anticlockwise, bayonet lock
3 deviate from from the bayonet 11 of fixture block 8, in this way, fixture block 8 is unlocked dropout；Energy storage torsional spring 2 releases energy, and please refers to Fig.4, connecting lever
Mechanism 1, towards anticlockwise, so that by the operation handle 36 of breaker switch to the left, makes breaker under the torsion of energy storage torsional spring 2
Contact apparatus closes a floodgate.
In conclusion the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
