Fig. 2 is in the structural representation of "on" position for the utility model.
Fig. 3 is the structural representation of the ratchet in the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Among Fig. 1 ~ Fig. 3, comprise torsion spring 1, the second ratchet 2, ratchet 3, the first ratchets 4, ratchet shaft 5, support 6, torsion axis 7, split pin 8, helical teeth 9, straight-tooth 10 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of manual energy storage combined floodgate self-locking device of vacuum circuit-breaker, comprises the ratchet shaft 5 that is fixedly mounted on rotationally on the support 6, is equipped with ratchet 3 on the ratchet shaft 5.
As shown in Figure 3, the ratchet 3 in the utility model is a kind of special compound ratchets, and its circumference is provided with helical teeth 9 and straight-tooth 10.Half circumference of ratchet 3 is provided with at least two helical teeth 9, and its other half circumference is provided with at least two straight-tooth 10.
Referring to Fig. 1, also be fixedly connected with torsion axis 7 on the support 6 again.Be with first ratchet 4, second ratchet 2 and torsion spring 1 on the torsion axis 7.The two ends of torsion spring 1 are separately fixed on first ratchet 4 and second ratchet 2.Be equipped with split pin 8 on the torsion axis 7 in torsion spring 1 outside, be used to prevent that torsion spring 1 from coming off.Helical teeth 9 matches with first ratchet 4, and straight-tooth 10 matches with second ratchet 2.
The course of work of the present utility model is as follows: as shown in Figure 1, when circuit breaker was in the separating brake position, second ratchet 2 was pulled up under the effect of separating brake external force, threw off release with the straight-tooth 10 on the ratchet 3, ratchet 3, first ratchet 4 are made stored energy operation with the direction of motion of compound ratchet 3 under external force; When certain corner was arrived in energy storage, the instantaneous work of permanent magnet mechanism closed a floodgate and moves, and reaches closing position as shown in Figure 2, the active force that acts on this moment on second ratchet 2 is removed, second ratchet 2 compresses the straight-tooth 10 on the compound ratchet 3 under the effect of torsion spring 1, realize the location self-locking reliably.After finishing sub-switching operation, circuit breaker is when the separating brake position, and second ratchet 2 is drawn back again under the effect of separating brake external force, finishes release, prepares for carrying out manual manpower energy storage closing operation once more.
The utility model has guaranteed that by being provided with the compound ratchet of two kinds of profiles of tooth and cooperating of two ratchets circuit breaker is in self-locking state when closing position, only just can carry out manual manpower energy storage closing operation after the separating brake position is by the release of separating brake external force.The utility model is simple in structure, reliable, has guaranteed the orderization of breaking-closing operating, has guaranteed processing safety, can prevent effectively because the misoperation of human factor.
