Description of the embodiments
Referring to fig. 1-4, the embodiment is a quick-plug electricity-taking ring main unit with a program lock device, which comprises a cabinet body, wherein the cabinet body is provided with a mechanism room 1 and a quick-plug electricity-taking room 2, the mechanism room 1 is provided with a mechanism room door, the quick-plug electricity-taking room 2 is provided with an electricity-taking room door 3, the mechanism room door is provided with a door lock a, the electricity-taking room door 3 is provided with a door lock B5, the door lock a and the door lock B5 share a key, the door lock a and an operating mechanism are provided with a linkage mechanism, the specific structure of the linkage mechanism is similar to that described in patent publication number CN105186295a, and the linkage mechanism has the following functions: only when the operating mechanism is in the opening state, the key is allowed to be pulled out from the door lock A; the door lock B5 is mechanically interlocked with the door frame of the electricity taking room, and the mechanical interlocking has the following functions: the key is allowed to be pulled out from the door lock B5 only when the access chamber door 3 is closed.
Further, the mechanical interlocking comprises a locking plate 7 arranged on a door frame of the electricity taking room 2, and a fixing support 4 arranged on a door 3 plate of the electricity taking room, wherein the cross section of the fixing support 4 is U-shaped, a sliding support 9 is arranged in the fixing support 4, a wedge-shaped plate 8 is arranged at the lower end of the locking plate 7, a lock hole matched with a lock pin 6 of a door lock B5 is arranged at the upper end of the locking plate 7, a cross beam 12 matched with the wedge-shaped plate 8 is arranged at the lower end of the sliding support 9, a baffle 10 is arranged at the upper end of the sliding support 9, the baffle 10 is used for shielding the lock pin 6 of the door lock B5, and a yielding hole 11 is arranged below the baffle 10.
Further, a limiting pin is arranged at the lower end of the fixed support 4 and used for limiting the limiting position of the sliding support 9 in the sliding mode.
Further, the cross member 12 is formed of an L-shaped bent plate.
According to the embodiment, the lock plate 7 is arranged on the door frame of the electricity taking room door 3, the lock hole is arranged at the upper end of the lock plate 7, the wedge-shaped plate 8 is arranged at the lower end of the lock plate, so that when the electricity taking room door 3 is closed, the cross beam 12 drives the whole sliding support 9 to ascend along the inclined plane of the wedge-shaped plate 8, when the electricity taking room door 3 is completely closed, the sliding support 9 ascends to the top, and at the moment, the lock pin 6 of the door lock B5 is just aligned with the abdicating hole 11, and therefore, a key can be rotated, and the lock pin 6 is inserted into the lock hole and pulled out of the key; when the electric taking room door 3 is opened, the sliding bracket 9 is not supported by the wedge-shaped plate 8, so that the electric taking room door descends, and the baffle 10 just shields the lock pin 6, so that the key cannot rotate, and the key cannot be pulled out.
The working principle of this embodiment is as follows: the door lock A and the door lock B5 share a key, so that only one door can be opened at the same time, and when the circuit breaker is in a closing state, the door lock A is locked through the interlocking mechanism, so that the key cannot be pulled out, and at the moment, the door lock B5 cannot be opened through the key to perform power-taking operation; when the temporary power taking is needed, the breaker is firstly opened, the interlocking mechanism is unlocked, so that a key can be pulled out of the door lock A, then the door lock B5 is opened by using the key, and the power taking operation is carried out, so that the door lock A and the door lock B5 form a program lock relation; when power is temporarily taken out, the door of the power taking chamber 2 is in an open state, and at the moment, the sliding bracket 9 of the mechanical interlocking device descends under the action of self gravity, and the lock plate 7 descends accordingly, so that the lock pin 6 of the door lock B5 is shielded, the key cannot rotate, and cannot be taken out, and therefore the door lock A cannot be opened by using the key.
