Description

Technical Field

[0001] The present application relates to the technical field of electric power installation, and in particular to a wiring protection device for electric power installation engineering. Background Art

[0002] During the construction of power installation projects, cables need to be wired, and the wiring points are relatively fragile and need to be protected. Wiring protection devices are devices used to protect wire joints. They are usually made of insulating materials and can cover the wire joints to prevent the joints from being hit or rubbed by external objects, thereby protecting the wire joints from damage.

[0003] Application No. 202320438832.6 discloses a wiring protection device for power installation projects, including a wiring slot, a pressure sensor, an alarm, a positioning slot and a stretching buffer mechanism, etc. Through the setting of the stretching buffer mechanism, when the cable is pulled during use, the wiring protection device for the power installation project can continuously apply a force opposite to the pulling direction to the cable through the buffer spring, thereby buffering the tension exerted on the cable. At the same time, through the setting of the card slot, the cable has a certain buffer distance, thereby ensuring the protection performance of the wiring protection device for the power installation project. Through the setting of the pressure sensor and the alarm, when the cable is pulled to the maximum buffer distance, the alarm can be used to issue an alarm to promptly remind the surrounding personnel, thereby preventing the cable from being loosened or even broken due to excessive tension. At the same time, through the setting of the positioning block and the positioning slot, it is convenient for subsequent staff to fix the first box body and the second box body, thereby improving the practicality of the wiring protection device for the power installation project.

When the cable is subjected to tension, the slider will slide toward the wire inlet, and the rotating shaft will rotate with the movement of the power cable, so that the two The power cable wrapped around the limit rod is straightened to release the reserved length for use when the slider moves horizontally. After the stretching is completed, the reset spring will squeeze the slider back to the other side of the slide slot, and the support spring will also pull the two ends of the support plate back to their original position to re-store the reserved length of the cable, thereby improving the stability of the device when it is pulled. At the same time, the interface can be squeezed and fixed by the telescopic rod, the upper arc plate and the lower arc plate. After the power cable is connected in the wiring slot, the length of the telescopic rod is adjusted to make the upper arc plate move up and down, and cooperate with the lower arc plate below to squeeze the cable interface, thereby further ensuring the stability of the interface.
