AI Technical Summary

Technical Problem

In high-dust environments, strong winds generated by high-speed trains can enter the housing through the ventilation holes of the primary and secondary fusion ring network box, causing dust accumulation, affecting electrical components, and reducing the operational reliability and lifespan of the equipment.

Method used

The device uses a combination of tape and magnets. Strong winds drive the fixed blocks to move, automatically replacing the tape to absorb dust. The dust enters the housing through the air duct, and gear transmission is used to rewind the waste tape, preventing dust from entering the housing.

Benefits of technology

It effectively reduces dust entering the enclosure, extends equipment life, improves the operational reliability and maintenance-free level of the equipment in high dust environments, and enhances the environmental adaptability and intelligent self-maintenance capability of the ring main unit.

Abstract

The invention relates to the technical field of primary and secondary fusion ring main units, and discloses an intelligent environment-friendly primary and secondary fusion ring main unit which comprises a box body, a ventilation box is arranged on the box body, a ventilation hole for connecting the box body and external air is formed in the ventilation box, an air channel communicated with the ventilation hole is formed in the ventilation box, and a fixing plate is arranged in the air channel. An adhesive tape used for adhering dust is rotationally connected to the fixing plate, the adhesive tape is located on the moving path of air entering the air channel after being unfolded, dust mixed in strong wind can be adsorbed by the adhesive tape and then enters the box body through the air channel, and therefore a large amount of dust is prevented from being deposited in the box body; pollution and chemical erosion of dust to key equipment such as the internal ring main unit are reduced, the service life of the equipment is prolonged, the ring main unit can block invasion of a large amount of dust brought by strong wind even in high-dust environments such as mines and industrial areas, and the environmental adaptability and operation reliability of the ring main unit are further improved.
