Cable fireproof device and using method thereof

Abstract

The invention relates to a cable fireproof device. The cable fireproof device comprises a pipeline, wherein the pipeline is provided with a rectangular inserting groove and a rectangular inserting plate; a temperature sensor, a control device and an automatic extinguisher are arranged at the bottom rear part of the pipeline; an unloading groove is formed in the rear wall of the pipeline, a bottom plate is arranged on the rear wall of the pipeline, and a sand layer is stuffed in the unloading groove; chock blocks are arranged on the lower edge of the front end surface of the unloading groove; rotating shafts and claws are arranged in front of the bottom plate; a connecting rod is connected between the claws, and is provided with a chock ring and a compression ring; a speed reducing motor, a lead screw and a coil are also arranged on the side wall of the pipeline, and a lug, a cover plate, a torsion spring, a permanent magnet and an electromagnet are also arranged on the pipeline; a standing plate and a horizontal plate are arranged at the middle of the bottom plate of the pipeline. A using method of the cable fireproof device is performed through the following manner of sending an alarm, performing self-extinguishing, performing burying, performing sealing and the like. According to the cable fireproof device disclosed by the invention, varied fire preventing and extinguishing manners of sending the alarm, controlling the automatic extinguisher to extinguish a fire, burying cables with the sand layer, sealing the pipeline and the like can be selected according to different temperature.

Description

technical field [0001] The invention relates to the technical field of cable fire protection, in particular to a cable fire protection device and a use method thereof. Background technique [0002] With the development of economy and society and the upgrading of power equipment, power cables are widely used for their advantages of saving ground space and low ground fault rate of cable lines. However, when power cables are used, insulation damage is more likely to occur due to materials or construction reasons, causing breakdown and fire at the cable head, and there have also been cases where the cable caught fire due to fire in the surrounding environment of the cable, resulting in power interruption and serious economic losses; therefore , how to carry out fire resistance to the cable is a very important topic in the power system. [0003] Application date 2014.09.01, application number 201410456144.8 patent discloses a cable automatic fire extinguishing device, including ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned device only uses a fire extinguisher to extinguish the fire, and the fire extinguishing effect is single, and the fire extinguishing effect is limited. If the surrounding environment of the cable catches fire and the fire is relatively large, a single fire extinguisher is obviously not enough to extinguish the fire.
