Description

Communication base station is with safe fire prevention cable pit

Technical Field

The invention belongs to the field of communication facilities, and particularly relates to a safe fireproof cable trench for a communication base station.

Background

A large number of cables are arranged in a communication base station for power supply and signal transmission, so that most communication base stations are provided with cable trenches for ensuring safe and orderly arrangement of the cables, the cable trenches are generally of concrete or brick structures, and the tops of the cable trenches are covered by cover plates.

Because of load and short-circuit current long-time effect, the insulating epidermis of cable conductor is easy ageing, and reasons such as cable joint contact failure local heating, all easily lead to taking place conflagration incident in the cable pit, however traditional cable pit only is equipped with the shutoff partition wall in entering building department, smoke and fire to indoor the spreading diffusion when preventing that the cable from catching fire, and do not possess the ability of in time automatic fire extinguishing, in case the conflagration takes place, the condition of a fire is difficult to obtain effective control in the past, will cause huge economic loss, influence communication base station's normal use, the life of giving people brings inconvenience.

To this end, we propose a fire-proof safety cable trench for a communication base station to solve the above problems.

Disclosure of Invention

The invention aims to provide a safe fireproof cable trench with automatic fire extinguishing capability for a communication base station, aiming at the problem that the fire condition is difficult to effectively control in the early stage.

In order to achieve the purpose, the invention adopts the following technical scheme: a safety fireproof cable trench for a communication base station comprises a trench body, a cable conductor support and a cover plate, wherein the trench body is arranged in an inverted trapezoid shape, a fixing baffle plate which is vertically arranged is fixedly arranged on the inner bottom surface of the trench body, a sliding groove is formed in the fixing baffle plate, a fireproof plate is connected to the side wall of the sliding groove in a sealing and sliding mode, evaporation liquid is filled in an airtight space formed by the lower portion of the fireproof plate and the sliding groove, a fire extinguishing box is fixedly arranged on the lower surface of the cover plate, fire extinguishing agents are filled in the fire extinguishing box, a groove matched with the fireproof plate is formed in the bottom surface of the fire extinguishing box, a pressing plate is connected to the inner side wall of the fire extinguishing box in a sealing and sliding mode, a rotating ring is rotatably connected to the side wall of the fire extinguishing box, a plurality of fire extinguishing spray pipes are arranged on the outer side wall of the rotating ring, and the side wall of the fire extinguishing spray pipe is provided with spray holes.

The invention has the advantages that:

when the internal cable conductor of ditch is because of ageing, when reasons such as short circuit cause the conflagration, the internal temperature of ditch sharply risees, evaporating liquid in the spout evaporates in high temperature environment, the volume inflation, promote the PLASTIC LAMINATED upwards slides, separate the cable conductor support of ditch body both sides, avoid the intensity of a fire to stretch, the PLASTIC LAMINATED enters the incasement that goes out a fire and promotes the clamp plate upwards to slide by the fluting, then the fire extinguishing agent of the incasement that goes out a fire is extruded and by the orifice blowout in the spout that goes out a fire, when the fire extinguishing agent blowout, give a reverse reaction force of the spout that puts out a fire, promote the spout and the rotating ring that put out a fire and rotate, then the fire extinguishing agent is evenly sprayed cable conductor support surface below, the condition of a fire on the cable conductor on the quick suppression, make the.

Preferably, the fireproof plate is an aluminum silicate light fireproof plate.

Preferably, the evaporation liquid is butyl acetate solution.

Preferably, the upper end of the fire extinguishing pipe is fixedly provided with a permanent magnet, the bottom surface of the cover plate is fixedly connected with a spiral coil, the upper surface of the cover plate is provided with an LED warning lamp, and the LED warning lamp is electrically connected with the spiral coil.

The extinguishing spray pipe drives the permanent magnet block to rotate, and according to the electromagnetic induction principle, when the magnetic flux in the closed coil changes, induced current is generated in the closed coil, then the induced current is generated in the spiral coil, and the LED warning lamp emits light to play a warning role, so that a worker of a telecommunication base station can find the fire in a ditch body in time, and can quickly take extinguishing maintenance measures.
