Description

Lower door interlocking device of upper isolation environment-friendly cabinet

Technical Field

The utility model relates to a looped netowrk cabinet technical field, concretely relates to last lower door interlock who keeps apart environmental protection cabinet.

Background

The environment-friendly cabinet is an existing mature product and is divided into an upper isolation environment-friendly cabinet (with an isolation switch on top) and a lower isolation environment-friendly cabinet (with an isolation switch on bottom); the general principle is as follows: set up isolator, isolator operating device, circuit breaker and circuit breaker operating device in the environmental protection cabinet, the interior cutter arbor of isolator operating device control isolator is keeping apart closing, keeps apart separating brake (also be ground connection separating brake simultaneously) and the ground connection closes between these three stations work, and the operation of separating brake, closing is carried out to the vacuum bubble in the circuit breaker of circuit breaker operating device control.

The isolation operating mechanism and the circuit breaker operating mechanism belong to the existing mature operating mechanisms, and detailed description on the specific structures is omitted; the operating principle of the isolation operating mechanism and the circuit breaker operating mechanism is roughly as follows:

the isolation operation mechanism comprises an isolation operation shaft and a grounding operation shaft, the isolation operation shaft rotates between two stations of isolation switching-on and isolation switching-off, and the grounding operation shaft rotates between the grounding switching-off and the grounding switching-on in a reciprocating manner;

the circuit breaker operating mechanism comprises a closing button, a closing half shaft, an opening button, an opening half shaft and an output shaft, wherein the closing button can be pressed to drive the closing half shaft to perform closing rotation so as to drive the output shaft to output closing rotating force, and the opening button can be pressed to drive the opening half shaft to perform opening rotation so as to drive the output shaft to output opening rotating force;

for the upper isolation environment-friendly cabinet (the isolation operation mechanism is on, and the breaker operation mechanism is under), the following two points are ensured in order to ensure the safety during operation; 1. when the cabinet door is in a closed state, the grounding operation shaft rotates to a grounding opening state and is in a closing state, and when the breaker is in the opening state, the cable chamber cabinet door cannot be opened; 2. when the cable chamber cabinet door is in an open state, the breaker can not be opened.

In current patent, disclose an upper isolation environmental protection cabinet door interlocking device in the patent of publication No. CN214848338U, it includes cabinet door, door lifting lever, door lifting driving plate and backing pin, when the circuit breaker switches from closing state to separating brake state, door lifting driving plate anticlockwise rotation contradicts with the backing pin, and door lifting lever can not the rebound, and the cabinet door can not be dismantled at last, but this kind of contact pattern's defect lies in: when switching from the combined floodgate state to the separating brake state, only contact point is carried to the door and is driven board and backing pin, because the part of whole environmental protection cabinet is more and heavier, after long-time the use, the backing pin breaks off easily to the area of contact that the door was carried the driven board and is blocked pin is less, therefore stability is relatively poor.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model lies in overcoming the area of contact that the door among the prior art carried the driving plate and kept off the round pin less, leads to the relatively poor defect of stability to a lower door interlock that keeps apart environmental protection cabinet on that stability is strong is provided.

For this, the utility model provides an on keep apart environmental protection cabinet's lower door interlock, include with the interlocking lever of cable chamber cabinet door linkage and set up in last keep apart the environmental protection and counter lock the piece even, be provided with between interlocking lever and the interlocking piece and be used for linking aggregate unit between them, aggregate unit is including the conflict pole that is fixed in the interlocking lever lateral part and the conflict piece that links with the conflict pole, the fixed extension that is provided with in interlocking piece lateral part, when the circuit breaker switches to the separating brake state from combined floodgate state, the conflict pole is contradicted with the extension, conflict piece and interlocking piece are contradicted.

Further: the contact rod is arranged at one end, opposite to the connecting lock plate, of the connecting lock rod, one end of the contact rod is fixedly connected with the connecting lock rod, and the other end of the contact rod can be in contact with the lower end face of the extending portion when the breaker is opened.

And further: the end that slides that supports the contact piece includes the body, contradicts with chain piece conflict the end and with even locking lever sliding connection's the end that slides, when the circuit breaker separating brake, the end that slides removes towards the one end that is close to even locking plate from the one end of keeping away from even locking plate, it is rotatory and contradict with chain piece to support the end to be counter-clockwise.

Further: the utility model discloses a circuit breaker, including the contact rod, the contact rod is provided with waist type groove on, slide to serve and be provided with the slider, the slider can slide along the extending direction reciprocating of the end that slides, and when the circuit breaker was closed a floodgate, the slider drives the end that slides and removes from the one end of keeping away from even locking plate towards the one end that is close to even locking plate.

And further: be provided with on the chain piece and be used for rotating the spread groove of being connected with the conflict piece, the conflict piece still includes rotatory end, rotatory end department is provided with the pivot, inside the pivot was located the spread groove, when the circuit breaker separating brake, the conflict piece is anticlockwise rotation and the perpendicular rebound of conflict piece.

And further: the extension portion is arranged at one end of the interlocking piece facing the interlocking plate, and the extension portion and the interlocking piece are arranged in a vertical structure.

The utility model discloses technical scheme has following advantage:

1. the utility model provides a pair of go up lower door interlock who keeps apart environmental protection cabinet, the circuit breaker is when switching to the separating brake state from the combined floodgate state among the prior art, only the door carries driving plate and a contact point of backing pin, because the part of whole environmental protection cabinet is more and heavier, after long-time the use, the backing pin breaks easily, and the door carries the area of contact of driving plate and backing pin less, therefore stability is relatively poor, in order to solve this technical defect, set up between even locking lever and interlocking piece and be used for linking link gear between them, when the ground connection operating axis is in combined floodgate and the circuit breaker is in the separating brake state, conflict pole is contradicted with the extension, conflict piece and interlocking piece are contradicted, so just can realize the double-locking to interlocking piece, improve the stability of even locking piece, avoid generally like prior art, make after the backing pin fracture when the circuit breaker separating brake, cable chamber door also can be opened, influence staff's life safety.

2. The utility model provides a pair of go up lower door interlock of keeping apart environmental protection cabinet through the setting of extension, can guarantee behind the interlock pole rebound, the conflict pole can contradict with chain piece.

3. Through the setting of pivot and spread groove, can effectual fixed position to the contact.
