Description

Technical Field

[0001] This application relates to the technical field of protection devices, and more specifically, to a protection device for a power system. Background Art

[0002] In recent years, with the rapid development of the power industry, power system protection specifications have received increasing attention. As an important part of the operation of the power system, power system protection aims to ensure the reliable operation and safe use of the power system.

[0003] The prior art document with the publication number CN220042853U provides a cable fixing device. The cable fixing device is placed at a set location, and the cable is inserted into the device. Driven by a motor, the inner threaded rod starts to rotate, and the outer threaded rod moves upward under the action of the thread. It passes through the threaded hole of the top clamping arm and through the positioning nut for quick fixing, and then the bottom clamping arm is tightly combined with the top clamping arm, enabling the device to fully fix the cable. This makes it no longer necessary for staff to spend a lot of time installing the device during use, greatly improving the installation efficiency of the device and reducing the labor intensity of the staff.

[0004] Although this device has many beneficial effects, there are still the following problems: When staff cut and repair part of the cable erected at a high altitude, such as when the cable catches fire and part of the cable needs to be cut off and then a new section of wire is reconnected at the cut position of the cable, the above device is difficult to clamp and fix both ends of the cut cable, which is likely to cause the cable to directly fall and injure pedestrians, resulting in safety accidents. In view of this, we propose a protection device for a power system. Summary of the Utility Model

[0005] By providing a protection device for a power system in the embodiments of this application, the technical problem in the prior art that when staff cut and repair part of the cable erected at a high altitude, it is difficult to clamp and fix both ends of the cut cable, which is likely to cause the cable to directly fall and injure pedestrians, resulting in safety accidents, is solved. The technical effect of being able to clamp and fix the cable when staff cut and repair the cable erected at a high altitude to prevent the cable from directly falling and injuring pedestrians, resulting in safety accidents, is achieved.

[0006] The embodiments of this application provide a protection device for a power system, including: a support plate;

One side of the bottom of the connecting plate is fixedly connected with a support rod, and the bottom of the support rod is fixedly connected with a mounting bracket. A threaded groove is formed through the bottom of the mounting bracket, and a threaded rod is threadedly connected in the threaded groove. The top of the threaded rod is fixedly connected with a clamping plate for clamping and fixing the cable, so as to prevent the cable from falling and injuring pedestrians, causing safety accidents.

[0009] By adopting the above - mentioned technical solution, by setting the anti - dropping mechanism, when the staff cuts and repairs the cable erected at a high altitude, the cable can be clamped and fixed to prevent the cable from falling directly after being cut and injuring pedestrians, causing safety accidents.

[0010] Optionally, rubber pads are fixedly connected to the top of the clamping plate and the inner top of the mounting bracket. The pads are made of rubber material, which is convenient for protecting the cable.

[0011] By adopting the above - mentioned technical solution, by setting the pads, since the pads are made of rubber material and have a soft texture, when clamping and fixing the cable, they can protect the outer skin of the cable to a certain extent.

[0012] Optionally, the cross - section of the mounting bracket is U - shaped, so as to facilitate placing the cable inside the mounting bracket.

[0013] By adopting the above - mentioned technical solution, by defining the cross - section of the mounting bracket, the cable can be placed inside the mounting bracket along the open end of the mounting bracket.

Fixed plates are fixedly connected to both sides of the top of the connecting plate, and a plurality of jacks are formed on both sides of the top of the support plate. The top of the fixed plate is slidably connected through a plug rod, and the plug rod is located in the jack, so as to facilitate adjusting the distance between the two mounting brackets.

[0015] By adopting the above - mentioned technical solution, by setting the fixed plate, the plug rod and the jack, when the plug rod moves out of the jack, the positioning of the fixed plate and the connecting plate can be released, so as to facilitate the staff to move the connecting plate. The movement of the connecting plate can drive the mounting bracket to move through the support rod, and then facilitate the staff to adjust the distance between the two mounting brackets according to the cutting length of the cable.

[0016] Optionally, a pulling plate is fixedly connected to the top of the plug rod, and a spring is fixedly connected to the top of the fixed plate. The top of the spring is fixedly connected to the bottom of the pulling plate, which is convenient for preventing the plug rod from moving out of the jack randomly.

[0017] By adopting the above technical solution, by setting the pull plate and the spring, when the pull plate is pulled to drive the plug rod to move upward, the spring will be pulled, causing the spring to deform and increasing the resistance when the pull plate moves upward, thereby facilitating the prevention of the random upward movement of the pull plate and the plug rod.
