Description

Push-pull ring network cabinet door lock structure

Technical Field

The invention relates to the field of ring main unit matching devices in a power distribution network, in particular to a push-pull ring main unit door lock structure.

Background

With the continuous development of society, especially city, the quantity of the looped netowrk cabinet as one of important intermediate equipment in the distribution network constantly increases, in order to guarantee the looped netowrk cabinet normal operating safety, need lock the looped netowrk cabinet. The traditional method for locking the ring main unit is to arrange a device such as a hanging lug or a lock tongue on a cabinet door and then install a padlock, and the defects existing in the traditional method are obvious: firstly, the locker is exposed, the padlock is difficult to open in the outdoor wind, sun and rain environment, the padlock and devices such as a hanging lug or a lock tongue arranged on the padlock are easy to corrode and damage, and meanwhile, the padlock is exposed, so that the lock is easy to be stolen, and the traditional locking mode is basically not used at present. The door lock structure of the prior rotary ring main unit commonly adopted by the ring main unit is shown in figures 13 and 14, and mainly comprises a lock box arranged on a ring main unit door, a rotary handle arranged in the lock box, a hanging rod and a padlock used for locking the rotary handle in the lock box, a locking rod of a world rod type matched with the main unit body, a connecting piece arranged outside the lock box and used for connecting the rotary handle with the world rod in a transmission way, and a box cover which is matched with the lock box and designed to be lifted upwards. Compared with the traditional padlock structure, the safety, reliability and antitheft performance of the existing door lock structure are greatly improved, but the problems found in the actual use process are as follows: because the ring main unit is generally arranged on an outdoor green belt or a roadside and is easy to corrode and jam, the door lock structure used by the prior ring main unit adopts a structure that the ground rod is separated and combined through the rotary handle, and because the rotary lever is too small, when the rotary handle is rotated, if the connecting piece and/or the ground rod is jammed or deformed, the rotary handle is very laborious to rotate, the locking is very difficult, the working efficiency is seriously influenced, even the situation that the joint of the rotary handle or the joint of the connecting piece and the ground rod is broken due to the powerful rotation of an operation and maintenance worker occurs, and in the prior structure, the ground rod is directly connected with the connecting piece, so that the ground rod and the jack hole on the cabinet body are easy to be misaligned, and the locking is difficult; in addition, the box cover is of an upward-lifting structure, so that interference is generated in the operation when the box cover is used, and the unlocking and locking operation actions are influenced. Therefore, it is necessary to improve the existing widely used ring main cabinet door lock structure.

With the progress of technology, the existing ring main unit is provided with an intelligent door lock, for example, chinese patent document with publication number CN204189215U proposes a ring main unit lock with an intelligent recognition function, which realizes the opening and closing of the internal structure of the lock by recognizing whether the key is authorized, and such an intelligent lock has a stronger anti-theft function than a commonly used padlock, but the cost of modifying the existing ring main unit door lock into an intelligent lock on a large scale is higher and is not economical, and the existing intelligent lock also has the problems that the electric quantity of the key of the intelligent lock is not easy to control in actual use, and the operation and maintenance personnel often have the problem that the door cannot be opened when the key is not used on site.
