Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and in particular to a switch cabinet operation window and hinge structure with a safety interlock mechanism. Background Technology

[0002] The switchgear operating window (also known as the inspection window or observation window) is an openable window on a high-voltage switchgear used for safe operation, status observation, and equipment maintenance. It is a key interface for "human-machine interaction" in power equipment.

[0003] However, in existing equipment, the operating windows of traditional switchgear are usually connected by simple hinges, which only have basic opening and closing functions and lack a mandatory interlocking mechanism with the status of the circuit breaker. Maintenance personnel may suffer electric shock or arc burns due to misoperation (such as opening the window while it is energized). Therefore, a switchgear operating window and hinge structure with a safety interlocking mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a switch cabinet operating window and hinge structure with a safety interlocking mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a switch cabinet operation window and hinge structure with a safety interlocking mechanism, comprising a switch cabinet body, a control switch and two fixing blocks fixedly installed on one side of the switch cabinet body, a connecting column rotatably connected to the opposite side of the two fixing blocks, an operation window body fixedly connected to the connecting column, a locking block fixedly connected to one side of the operation window body, a locking hole provided on the upper surface of the locking block, and a locking structure and a pushing structure provided on the switch cabinet body;

[0006] The locking structure includes a rotating shaft that is rotatably connected through one side of the switch cabinet body. A first servo motor is fixedly connected to one side of the switch cabinet body. The output shaft of the first servo motor is fixedly connected to one end of the rotating shaft, so that the first servo motor drives the rotating shaft to rotate.

[0007] As a further description of the above technical solution:

[0008] The other end of the rotating shaft is fixedly connected to a rotating disk, and one side of the rotating disk is fixedly connected to a toggle post. The rotating shaft drives the rotating disk to rotate, which in turn drives the toggle post to rotate.

[0009] As a further description of the above technical solution:

[0010] A fixing plate is fixedly connected to one side of the interior of the switch cabinet body. A locking rod is slidably connected through the upper surface of the fixing plate. The locking rod is adapted to the locking hole. A moving column is fixedly connected to the upper surface of the locking rod. A sliding groove is opened on one side of the moving column. The interior of the sliding groove is slidably connected to a toggle column. The toggle column drives the moving column to move upward through the moving groove. The moving column drives the locking rod to disengage from the locking hole and release the locking of the operation window body.

[0011] As a further description of the above technical solution:

[0012] The pushing structure includes a fixed column fixedly connected inside the switch cabinet body. A movable groove is opened on one side of the fixed column, and a threaded rod is rotatably connected in the movable groove. A second servo motor is fixedly connected to one side of the switch cabinet body. The output shaft of the second servo motor is fixedly connected to one end of the threaded rod, so that the second servo motor drives the threaded rod to rotate.

[0013] As a further description of the above technical solution:

[0014] A movable block is threadedly connected to the threaded rod. The movable block is slidably connected in the movable groove. A movable plate is fixedly connected to one side of the movable block. The threaded rod drives the movable block to move away from the second servo motor, and the movable block drives the movable plate to move.

[0015] As a further description of the above technical solution:

[0016] A connecting rod is fixedly connected to one side of the main body of the operation window. A push rod is rotatably connected to the bottom of the connecting rod. The other end of the push rod is rotatably connected to the upper surface of the moving plate. The moving plate pushes the push rod to move, and the other end of the push rod pushes the connecting rod. The connecting rod pushes the main body of the operation window to move, so that the main body of the operation window opens in a fan shape with the connecting column as the axis.

[0017] As a further description of the above technical solution:

[0018] A PLC control module is fixedly connected to one side of the main body of the switch cabinet. The PLC control module is electrically connected to the control switch, the first servo motor, and the second servo motor, and controls the operation of the first servo motor and the second servo motor through the PLC control module.

The interior of the sliding groove is slidably connected to the toggle column 704. When the control switch 2 is pressed, the circuit breaker is tripped through the control switch 2. At the same time, a signal is fed back to the PLC control module 3. The PLC control module 3 controls the first servo motor 701. The first servo motor 701 drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the rotating disk 703 to rotate. The rotating disk 703 drives the toggle column 704 to rotate.

The other end of the push rod 907 pushes the connecting rod 906, and the connecting rod 906 pushes the main body of the operation window 6 to move, so that the main body of the operation window 6 opens in a fan shape with the connecting column 5 as the axis, without the need for manual opening by the operation and maintenance personnel, further protecting the safety of the maintenance personnel.

[0035] Working principle: Pressing control switch 2 trips the circuit breaker and simultaneously sends a signal to PLC control module 3. PLC control module 3 then controls the first servo motor 701, which in turn drives the rotating shaft 702. The rotating shaft 702 drives the rotating disk 703, which in turn drives the actuating column 704. The actuating column 704, via a moving slot, moves the moving column 707 upwards. The moving column 707 then disengages the locking rod 706 from the locking hole, releasing the lock on the main body 6 of the operating window and preventing electric shock or arc burns caused by operator error. Therefore, the PLC control module 3 then controls the second servo motor 903, which drives the threaded rod 902 to rotate. The threaded rod 902 drives the moving block 904 to move away from the second servo motor 903. The moving block 904 drives the moving plate 905 to move. The moving plate 905 pushes the push rod 907 to move. The other end of the push rod 907 pushes the connecting rod 906. The connecting rod 906 pushes the main body of the operation window 6 to move, so that the main body of the operation window 6 opens in a fan shape with the connecting column 5 as the axis. This eliminates the need for manual opening by maintenance personnel, further protecting their safety.
