AI Technical Summary

Technical Problem

Existing explosion-proof cable trays have poor sealing between the cable and the end plate, making it easy for dust and other impurities to enter. They also have insufficient connection strength, resulting in a decrease in tensile strength.

Method used

It adopts a structure that combines an arc-shaped clamping plate with an inlet pipe. The cable is stably clamped by the rotation of the squeezing block. It is equipped with a sealing ring and a dry powder bag. The sealing ring seals the contact surface, and the dry powder bag releases extinguishing agent to prevent explosion in the event of an electric spark or arc.

Benefits of technology

It achieves stable cable clamping and good sealing, prevents dust from entering, improves connection strength, avoids cable explosion and breakdown, and enhances the practicality of explosion-proof cable trays.

Abstract

The utility model discloses a cable explosion-proof groove box which comprises a box body, a cover plate is arranged above the box body, wire inlet pipes are arranged at the lower ends of the two sides of the box body, arc-shaped clamping plates are arranged at the upper ends of the sides, away from the box body, of the wire inlet pipes, and two symmetrical first fixing plates are arranged on the sides, away from pin shafts, of the wire inlet pipes. A shaft rod is arranged between the two first fixing plates, the middle of the shaft rod is fixedly connected with a threaded rod, an extrusion block is arranged at the position, located above the second fixing plate, of the threaded rod, L-shaped clamping plates are arranged on the two sides of the lower portion of the cover plate, connecting plates are inserted into the L-shaped clamping plates, and the lower portions of the two connecting plates are fixedly connected with a containing groove. A plurality of supporting rods distributed at equal intervals are arranged at the lower end in the containing groove, and a dry powder bag is arranged above the supporting rods. The explosion-proof groove box is good in protection effect and good in sealing performance, the connection stability of the explosion-proof groove box and the cable is effectively improved, and the practicability of the explosion-proof groove box is improved.
