Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a safety protection device for electrical secondary maintenance. Background Technology

[0002] In the operation and maintenance of electrical equipment, secondary circuits, as a crucial component of control, protection, measurement, and signal transmission, directly impact the stable operation of the entire power system through the safety and reliability of their maintenance work. Electrical secondary maintenance work typically requires a de-energized state. To prevent accidental energization or misoperation during maintenance, which could lead to personal injury or equipment damage, effective safety measures are essential. Currently, commonly used on-site safety measures rely heavily on traditional mechanical locks, warning signs, or temporary barriers. These methods generally suffer from inconvenient installation, poor adaptability, and limited protective effectiveness. Especially when dealing with control boxes and switchgear of different models or sizes, the fixing methods are often difficult to adapt quickly, resulting in lengthy installation times and reduced maintenance efficiency. Furthermore, for disconnecting switches or air switches that may be accidentally closed, the lack of effective mechanical limit devices means that relying solely on manual confirmation or program control cannot completely eliminate operational risks, posing certain safety hazards. Therefore, we propose a safety protection device for electrical secondary maintenance. Utility Model Content

Two first connecting holes are opened on the left and right sides of the rear end of the mounting bracket. A mounting groove is opened in the middle of the rear end of the mounting bracket, and a limit component is fixedly installed in the middle of the rear end of the mounting groove.

[0006] The fixing assembly includes an extension arm, a connecting plate is fixedly connected to the front end of the extension arm, two connecting plates are opened through the front end of the connecting plate, a threaded sleeve is fixedly connected to the end of the extension arm near the control box, an adjusting nut is rotatably connected to the inner surface of the threaded sleeve, an adjusting sleeve is rotatably connected to the end of the adjusting nut near the mounting plate, and a clamping plate is fixedly connected to the end of the adjusting sleeve near the mounting plate.

[0007] Preferably, the length of the mounting bracket is greater than the width of the control box, and the rear ends of the two first connecting holes on the same side are fixedly installed with the fixing component.

The two connecting brackets are rotatably connected to a rotating rod, and the rear end of the rotating rod is rotatably connected to a device for adjusting the overall angle of the limiting plate. After the adjustment is completed, the limiting plate is rotated for fine adjustment to limit the position of the switch and protect the personal safety of maintenance personnel.

[0014] Preferably, the area of ​​the fixing plate is equal to the area of ​​the mounting groove, and the length of the limiting plate is less than the width of the knife gate.
