Technical Field

The invention relates to a misoperation-preventive locking device, in particular to a misoperation-preventive locking device for a switch cabinet.

Background

In order to reduce the occurrence of human misoperation accidents of power system stations, the current misoperation-preventive locking system in the power system stations is widely applied. In the maloperation locking system construction of present electric power system station, for example, when installing new tool to lock on the cabinet door of cubical switchboard, need punch, beat operations such as cabinet door even, not only installation operation is inconvenient, the installation effectiveness is low, vibrations during the installation can influence cubical switchboard normal operating moreover, arouses switch mistake accident such as jump easily, therefore needs to have a power failure to install, influences electric power system's normal operating.

Disclosure of Invention

The invention aims to provide a switch cabinet anti-misoperation locking device which is not only free of punching installation, convenient in installation operation and high in installation efficiency, but also capable of performing installation operation under the condition that a switch cabinet is not powered off.

The technical scheme of the invention is as follows:

a switch cabinet anti-misoperation locking device comprises a cabinet body and a cabinet door, wherein the cabinet door is locked on the cabinet body through a locking bolt, the switch cabinet anti-misoperation locking device also comprises a locking device, the locking device comprises a padlock, a locking main body and a limiting baffle plate, the locking main body comprises a bottom plate, two side plates connected with the bottom plate and side plate through holes arranged on the side plates, the two side plates are positioned at the same side of the bottom plate, the bottom plate is provided with a screw rod through hole, the screw rod through hole extends towards one side of the bottom plate and forms a screw rod inlet at one side of the bottom plate, the screw rod through hole is positioned between the two side plates, the bottom plate is provided with a guide through hole communicated with the screw rod through hole, one side surface of the bottom plate, which is opposite to the side plates, is provided with a limiting groove communicated with the screw rod through hole, the limiting groove and the guide through hole are positioned at two opposite sides, the other end of the rocker passes through a notch of the limiting groove and is positioned outside the limiting groove, a limiting block is arranged on one side of the rocker facing the limiting groove, the locking bolt passes through the screw rod through opening, the bottom plate is positioned between the cabinet door and the head of the locking bolt, the side plate and the cabinet door are positioned on two opposite sides of the bottom plate, the limiting baffle is provided with a limiting opening matched with the limiting block, the limiting baffle is inserted in the guide through hole in a sliding manner and can pass through the screw rod through opening to extend into the limiting groove, after the limiting baffle in the guide through hole passes through the screw rod through opening and extends into the limiting groove, the limiting baffle is used for preventing the locking bolt from being separated from the screw rod inlet, the locking bolt locks the bottom plate and the cabinet door on the cabinet body together, and the other end of the rocker is pressed into the limiting; the head of the locking bolt is provided with an operation hole used for being matched with a wrench to screw or unscrew the locking bolt, a lock beam of the padlock penetrates through holes of the side plates of the two side plates to lock the padlock on the side plates, and the lock beam positioned between the two side plates is used for preventing the wrench from extending into the operation hole.

When the locking device is actually installed, firstly, the locking bolt is unscrewed, so that the bottom plate and the warped plate can be inserted into a gap between the head of the locking bolt and the cabinet door, the locking bolt is not required to be completely disassembled, the operation efficiency can be improved, and the problem that an operator mistakenly touches a conductive piece in the switch cabinet to cause electric shock risk due to the fact that the cabinet door is opened after the locking bolt is completely disassembled is solved; secondly, inserting the bottom plate between the head of the locking bolt and the cabinet door, and enabling the locking bolt to enter the screw rod through opening through the screw rod inlet; then, the limiting baffle in the guide through hole penetrates through the screw rod through hole and is inserted into the limiting groove, so that the limiting baffle abuts against the side wall of the limiting groove, and at the moment, the limiting baffle is used for preventing the locking bolt from being separated from the screw rod inlet; thirdly, locking a locking bolt, locking the bottom plate and the cabinet door on the cabinet body together through the locking bolt, pressing the other end of the warped plate into the limiting groove to enable a limiting block to be inserted into the limiting opening, so that the limiting baffle is prevented from moving out of the limiting groove, and the limiting baffle is ensured to play a role in preventing the locking bolt from coming out of the screw rod inlet; fourth, pass the curb plate through-hole of two blocks of curb plates with the lock beam of padlock, locked the padlock on the curb plate to block the spanner through the lock beam between two blocks of curb plates and stretch into the handle hole of locking bolt, so, before opening and taking off the padlock, operating personnel can't stretch into the handle hole of locking bolt through the spanner, unscrew locking bolt, and open the cabinet door, in order to reduce the emergence of artificial maloperation accident. The cubical switchboard of this scheme prevents mistake blocking device not only need not the installation of punching, installation convenient operation, installation effectiveness are high, produces the vibration hardly in the installation moreover, therefore can be under the circumstances that the cubical switchboard does not have a power failure, installation operation, and operation safe and reliable.

Preferably, an extension of the axis of the locking bolt intersects the shackle, and the shackle between the two side plates is adjacent to the head of the locking bolt. So, can guarantee before opening and taking off the padlock, operating personnel can't stretch into the handle hole of locking bolt through the spanner, unscrew locking bolt, and open the cabinet door to reduce the emergence of artificial maloperation accident.

Preferably, the rocker is integrally formed with the base plate. Thus, the method is convenient for actual production and manufacture.

Preferably, the two side plates are parallel.

Preferably, the two side plates are integrally formed with the bottom plate. Thus, the method is convenient for actual production and manufacture.

Preferably, the side panels are perpendicular to the bottom panel.

Preferably, the limit baffle is parallel to the bottom plate.

Preferably, the limit baffle is perpendicular to the side plate.

The invention has the beneficial effects that: the installation of not only need not to punch, installation convenient operation, installation effectiveness are high, produce the vibration in the installation moreover hardly, therefore can install the operation under the circumstances that the cubical switchboard does not have a power failure, and operate safe and reliable.
