Abstract
The technical scheme of the utility model provides a spring energy storage indicating device for a control mechanism. The spring energy storage indicating device is characterized by comprising a shaft, the shaft is connected with the front end of a spring pull rod through a bearing and fixed on an energy storage driving wheel, a stud is fixed on the shaft, one end of a shifting fork is connected with the stud, and the other end is connected with an indicating arrow on an energy storage indication board, so that the indicating arrow can rotate along with the shaft. The indicating device provided by the utility model can reliably indicate the energy storage state of a closing spring and is free from curve and fracture.
Description
Technical field
The utility model relates to a kind of high pressure equipment for power transmission and distribution breaker operation mechanism switching-in spring energy storage indicating device, and major function is to solve the positive energy storage state that shows the switching-in spring of spring mechanism of circuit breaker.
Background technology
Circuit breaker is a switchgear important in the electric power system, undertaking the double action of control and protective circuit, and in circuit breaker, operating mechanism is its vitals again.In operating mechanism, give the switching-in spring energy storage by stored energy mechanism.When circuit breaker broke off, switching-in spring is energy storage.During combined floodgate, switching-in spring releases energy.When switching-in spring had discharged energy, motor began to the switching-in spring energy storage.
Therefore, need an indicating device to indicate the energy storage state of switching-in spring, still, existing indicating device is unreliable, has more existing indication bending and phenomenon of rupture.
Summary of the invention
It is reliable that the purpose of the utility model provides a kind of indication, is not prone to the indicating device of the switching-in spring energy storage state of indication bending and phenomenon of rupture.
In order to achieve the above object, the technical scheme of the utility model has provided a kind of spring energy-storage indicating device of operating mechanism, it is characterized in that: comprise axle; Axle links to each other with the front end of spring pull bar through bearing; Axle is fixed on the energy storage driving wheel, and double-screw bolt is fixed on the axle, and an end of fork links to each other with double-screw bolt; The other end connects the arrow on the energy storage direction board, makes arrow follow the axle rotation.
Further, an end of said fork links to each other with said double-screw bolt through kidney slot.
The utility model provides a kind of indicating device of indicating reliable switching-in spring energy storage state, and this indicating device can not bend and rupture.
Description of drawings
The spring energy-storage indicating device sketch map of a kind of operating mechanism that Fig. 1 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, the spring energy-storage indicating device of a kind of operating mechanism that the utility model provides comprises axle 8; Axle 8 links to each other with the front end of spring pull bar 9 through bearing; Axle 8 is fixed on the energy storage driving wheel 4, and double-screw bolt 7 is fixed on the axle 8, and an end of fork 6 links to each other with double-screw bolt 7 through kidney slot; The other end connects the arrow on the energy storage direction board 2, makes arrow follow axle 8 rotations.
Rotate when 1 energising of mechanism's energy storage motor,, drive energy storage driving wheel 4 and rotate counterclockwise through Bevel Gear Transmission; Axle 8 is fixed on the energy storage driving wheel 4, and therefore, axle 8 rotates counterclockwise around energy storage driving shaft 4 centers; Spring pull bar 9 is connected through bearing with axle 8, and spring pull bar 9 is to left movement, spring stop 12 and spring pull bar employing bolt; Spring pull bar 9 drives spring stop 12 in the time of moving excessively and is moved to the left, thereby makes energy-stored spring 10 compressions carrying out energy storage action.
Double-screw bolt 7 is fixed on the axle 8; Double-screw bolt 7 rotates counterclockwise around energy storage driving shaft 4 centers, and fork 6 inserts in the double-screw bolt 7, and fork 6 is rotated counterclockwise around energy storage driving wheel 4 centers; Indicating arm 3 is one with fork 6 welderings; Arrow on the energy storage direction board 2 is fixedly connected with indicating arm 3, thereby arrow is rotated counterclockwise, and realizes deixis.
After spring energy-storage puts in place, stop, accomplishing energy storage state, energy storage direction board 2 upward arrow directions left.When spring energy release, motion conditions is opposite, gets back to initial condition.
