AI Technical Summary

Technical Problem

When insulating tape is exposed to the natural environment for a long time, it ages due to ultraviolet radiation, temperature changes and humidity, resulting in weakened adhesion, which makes it unable to effectively prevent current leakage and increases the risk of electric shock and short circuit.

Method used

The system employs wiring equipment, including a junction box, a flexible air-conducting assembly, a pressing assembly, and a screw assembly. Through a combination of a bladder-type docking assembly and a cylindrical metal assembly, gas sealing technology is used to seal the cable connection points. Automatic adjustment is achieved by combining a pressure sensor and a controller.

Benefits of technology

It effectively isolates external moisture, dust and impurities, adapts to minor cable deformation, improves the service life and versatility of the sealing structure, simplifies the operation process, reduces maintenance frequency, and improves work efficiency.

Abstract

This invention relates to the field of power maintenance technology and discloses a wiring device and method for power maintenance. The wiring device includes a junction box, a flexible air-conducting assembly, a pressing assembly, and a screw assembly. Both ends of the junction box are detachably connected to bladder-type docking assemblies. Each of the two bladder-type docking assemblies has a cylindrical metal assembly installed at one adjacent end inside the junction box, with the ends of the two cylindrical metal assemblies fitting together. This invention achieves connection and sealing of damaged sections of the cable through the bladder-type docking assemblies and the cylindrical metal assemblies. The screw assembly drives the pressing assembly to press and fix the battery cell in the cylindrical metal assembly, while simultaneously pushing the flexible air-conducting assembly downwards, guiding a fixed amount of gas into the bladder-type docking assembly to inflate and seal it. For cables of different diameters, the gas volume inside the bladder is adjusted through a pressure sensor, controller, alarm, and valve and air-pushing component on the air-conducting hose to ensure that the sealing structure provides good sealing and fixing for cables of different diameters.
