Abstract
The invention relates to a compound ratchet wheel used for a vacuum circuit breaker. The compound ratchet wheel comprises a disc-shaped ratchet wheel body and ratchets arranged on the circumference of the ratchet wheel body. The compound ratchet wheel is characterized in that the ratchets comprise oblique teeth and straight teeth; at least two oblique teeth are arranged on one half circumference of the ratchet wheel body; and at least two straight teeth are arranged on the other half circumference of the ratchet wheel body. The compound ratchet wheel has the following technical effects: through matching between the two types of ratchets and two pawls of a manual stored energy closing and self-locking device, the circuit breaker is ensured to be in the self-locking state in the closing position and can carry out manual stored energy closing only if the circuit breaker is unlocked by the external opening force in the opening position; and the compound ratchet wheel has simple and reliable structure, ensures sequential opening and closing operations and operation safety and can effectively prevent misoperation caused by human factors.
Description
Technical field
The present invention relates to the manual energy storage combined floodgate self-locking device of bistable-state permanent magnet mechanism high-pressure vacuum breaker, specifically a kind of compound ratchet that is used for vacuum circuit-breaker.
Background technology
The bistable-state permanent magnet mechanism high-pressure vacuum breaker is a kind of with the high-pressure vacuum breaker of bistable-state permanent magnet mechanism as the operating mechanism configuration.Use reliably for greater safety, this circuit breaker generally disposes manual closing mechanism.The requirement of manual closing mechanism safety operation is that circuit breaker can only can carry out manual manpower energy storage closing operation in the separating brake position, keeps breaking-closing operating to change in proper order, prevents effectively because the misoperation of human factor.Existing ratchet, the circumference of ratchet body is provided with the ratchet with a kind of profile of tooth, and this ratchet or helical teeth, or straight-tooth can't satisfy the requirement of manual closing mechanism safety operation.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of compound ratchet that is used for vacuum circuit-breaker is provided, this compound ratchet can keep the manual closing mechanism breaking-closing operating to change in proper order, guarantees that manual energy storage closing operation is safe and reliable.
According to technical scheme of the present invention: a kind of compound ratchet that is used for vacuum circuit-breaker, comprise disc ratchet body and be arranged on ratchet on the ratchet body circumference, described ratchet comprises helical teeth and straight-tooth, half circumference of described ratchet body is provided with at least two described helical teeth, and its other half circumference is provided with at least two described straight-tooth.
Described helical teeth and described straight-tooth all have four.
The center of described ratchet body offers centre bore.
Offer keyway on the described centre bore.
Technique effect of the present invention is: the present invention matches with two ratchets of manual energy storage combined floodgate self-locking device by the ratchet that two kinds of profiles of tooth are set, guaranteed that circuit breaker is in self-locking state when closing position, only after the separating brake position is by the release of separating brake external force, just can carry out manual manpower energy storage closing operation.The present invention 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.
Description of drawings
Fig. 1 is in the structural representation of gate-dividing state for using manual energy storage combined floodgate self-locking device of the present invention.
Fig. 2 is in the structural representation of "on" position for using manual energy storage combined floodgate self-locking device of the present invention.
Fig. 3 is a perspective view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention 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, centre bore 11, keyway 12, ratchet body 13, key 14 etc.
As shown in Figure 3, the present invention is a kind of compound ratchet 3 that is used for vacuum circuit-breaker, comprises disc ratchet body 13 and is arranged on ratchet on the ratchet body circumference, and the center of ratchet body 13 offers centre bore 11, offers keyway 12 on the centre bore 11.Ratchet among the present invention comprises helical teeth 9 and 10 two kinds of profiles of tooth of straight-tooth, and half circumference of ratchet body 13 is provided with at least two helical teeth 9, and its other half circumference is provided with at least two straight-tooth 10.
Preferably, helical teeth 9 and straight-tooth 10 all have four.
As shown in Figure 1 and Figure 2, when the present invention is applied to manual energy storage combined floodgate self-locking device, be installed on the ratchet shaft 5 by key 14, ratchet shaft 5 is fixedly mounted on the support 6 rotationally.Manually energy storage combined floodgate self-locking device also comprises torsion spring 1, the second ratchet 2, the first ratchets 4, torsion axis 7, split pin 8 etc.
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.
Manually the course of work of energy storage combined floodgate self-locking device is as follows: as shown in Figure 1, when circuit breaker is in the separating brake position, second ratchet 2 is pulled up under the effect of separating brake external force, throw 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 present invention matches with two ratchets of manual energy storage combined floodgate self-locking device by the ratchet that two kinds of profiles of tooth are set, guaranteed that circuit breaker is in self-locking state when closing position, only after the separating brake position is by the release of separating brake external force, just can carry out manual manpower energy storage closing operation.The present invention 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.
