Abstract
The utility model relates to an anti-maloperation electrical operation mechanism. The mechanism comprises a motor which drives a cam to rotate via a gear pair. The cam is disposed on an installing plate, and a positioning shaft is disposed on the cam and drives a slide block in a slide block mechanism to move up and down. The mechanism is characterized in that a groove is arranged in the installing plate; a blocking end of a blocking assembly extends into the groove and can freely move in the groove; when a breaker is switched on, the blocking end is pressed against the edge of the cam to make the cam not rotate; the other end of the blocking end is connected to the installing plate via a restoring mechanism, and restoring force of the restoring mechanism is far less than operation force acting on the cam; and when the positioning shaft is moving from a switch-on area to a switch-off area, the operation force acting on the cam overcomes the restoring force of the restoring mechanism to allow the blocking end of the blocking assembly to avoid the cam via the groove. A design is made for two important mechanisms of electrical operation, and dual protection effects are provided for prevention of electrical maloperation.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 1, the electrically operated institution of a kind of false action-proof that the utility model provides, comprise motor 1, motor 1 rotates by gear pair band moving cam 5, cam 5 is located on mounting panel 9, is provided with locating shaft 7 on cam 5, and the slide block 6 that locating shaft 7 drives in slide block mechanism moves up and down.
This utility model, to two important transmission mechanisms in existing electrically operated institution, plays respectively the function of false action-proof to electrically operated institution.
The false action-proof of first, cam mechanism:
Cam mechanism is very important parts mechanism in electricity behaviour's transmission mechanism.Locating shaft 7 is housed on cam 5, and cam 5 itself is not the dynamic balancing part, so, when impacting to being subject to brute force with vertical from side direction, be subject to the impact of cam 5 deadweights and inertia, by causing, misrouting of cam 5 is moving, thereby band movable slider 6 causes the misoperation of circuit breaker.
Moving for fear of misrouting of cam 5, must be when breaker closing, cam 5 forwards an extreme position to, is not subject to the impact of foreign impacts power.In the situation of circuit breaker in the state conversion, cam 5 must, in free rotation state, not be subject to the impact of stopping means again.
The utility model has designed a stopping element 8, and Fig. 2 is the state of circuit breaker in closing a floodgate.Locating shaft 7 on cam 5 is fixed on to the side close to from the backstop axle, can affect like this proper motion that locating shaft 7 is controlled slide blocks 6, because slide block 6 is gapped with coordinating of locating shaft 7.Locating shaft 7 is fixed on this position, even cam 5 opposite direction fast rotational also can not arrive the position of misoperation when being subject to impulse force.
In conjunction with Fig. 2 and Fig. 3, in the utility model, have U-shaped groove 10 on mounting panel 9, this U-shaped groove 10 is U-shaped groove, the stop end of stopping element 8 stretches in U-shaped groove 10 and can move freely therein, the edge that this stop end props up cam 5 after breaker closing can't rotate cam 5, and the other end of stopping element 8 is connected on mounting panel 9 via response agency, and the operating physical force on cam 5 is much larger than the restoring force of response agency.
Response agency comprises returning spring 22, and the two ends of returning spring 22 are connected and fixed with the other end and the mounting panel 9 of L shaped connecting lever 20 respectively.
As shown in Figure 4, cam 5 drives the separating brake zone 12 o'clock that locating shafts 7 turn to upper end, the slide block 6 of locating shaft 7 guiding just can make breaker open operation, otherwise, turn to the combined floodgate zone 11 o'clock of lower end, breaker closing, U-shaped groove is the rotation of limit stop assembly 8, allow stopping element 8 can limit cam 5 when closing a floodgate and rotate, can allow cam 5 jack-up backstop axles during separating brake.
When instant impact makes cam 5 along the traffic direction fast rotational, backstop axle restriction cam 5 rotates.There is the fixing of returning spring 22 lower end of backstop axle, can make braking roll paste tightly cam 5, and the backstop axle will block one side of cam 5 like this, and as shown in Figure 2, cam 5 can not surpass this extreme position, so cam 5 can not turn to open position.
When needs operation (manually with automatic) electricity behaviour, the operating physical force acted on cam 5 will be much larger than the spring force of returning spring 22, and cam 5 just can the gradient on cam 5 outwards eject the backstop axle along U-shaped groove like this, the completion status conversion.
In sum, this design can make cam 5 when being subject to instant impact, prevents that well cam 5 from misrouting movingly, and, when manual operation, also can not cause the stuck of cam 5.
The false action-proof of second portion, slide block:
In conjunction with Fig. 5 and Fig. 6, slide block mechanism comprises is located at mounting panel 9 suspension hook 13 and the slide block 6 on cam 5 one side dorsad, slide block 6 slides on guide rail 14, snap close 15 is located at slide block 6 by rotating shaft 16, snap close 15 can 16 rotate around the shaft, be provided with spacing hole 17 on an end of snap close 15, the limited post 18 be fixed on slide block 6 is positioned at this spacing hole 17, one end of spring 19 is connected with snap close 15, the other end is connected and fixed, when slide block 6, during in closing position, the other end that promotes snap closes 15 by spring 19 catches on suspension hook 13 and makes slide block 6 be positioned.
Be formed with the arc groove 20 matched with the outer circumference surface of locating shaft 7 on snap close 15, when locating shaft 7 is moved to separating brake zone 12 by the zone 11 of closing a floodgate, locating shaft 7 props up the rear promotion snap close 15 of this arc groove 20 and 16 rotates its other end made and throw off suspension hook 13 around the shaft.
When operation electricity behaviour changes circuit-breaker status, the locating shaft 7 on cam 5 starts to follow cam 5 and rotates, and turns to arc groove 20 places of snap close 15.Locating shaft 7 just can drive snap close 15 and rotate, and the rotation of snap close 15 can make snap close 15 separate with suspension hook 13, and slide block 6 just can move freely like this, and electricity behaviour just can realize the separating brake action.Snap close 15, because spacing reason can not rotated very large angle yet, causes separating brake not in place.
