Abstract

The utility model provides an aerify type fire prevention flame retarded cable, includes the sinle silk, is equipped with interior sheath, flame retardant coating and outer jacket, its characterized in that in proper order outside the sinle silk: a plurality of round pipes are filled in the fire-resistant layer, elastic hoses are arranged in the round pipes, and elastic connecting parts are arranged between the elastic hoses and the round pipes. The utility model provides an aerify type fire prevention flame retarded cable increases elastic hose in the pipe, makes the inside pressure increase after aerifing, when the cable takes place to melt, because powerful in the elastic hose, can press flame retardant gas to melting the department discharge rapidly.

Description

Inflatable fireproof flame-retardant cable

Technical Field

The utility model relates to the technical field of cables, especially an aerify type fire prevention flame retarded cable.

Background

In the utility model patent of the publication number CN212411651U, my company disclosed an inflation type fireproof and electricity-stealing prevention cable, set up the gas tube in the cable to fill into flame retardant gas, the gas tube fuses when taking place the conflagration, releases flame retardant gas, nevertheless because inside and outside concora crush, the effect that gas spilled over is not good, becomes to stop flowing after spilling over a small amount, and most gas still stops in the gas tube.

Disclosure of Invention

The utility model aims to solve the technical problem that an aerify type fire prevention flame retarded cable is provided, the volume of spilling out of the department flame retardant gas that melts is improved.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides an aerify type fire prevention flame retarded cable, includes the sinle silk, is equipped with interior sheath, flame retardant coating and outer jacket, its characterized in that in proper order outside the sinle silk: a plurality of round pipes are filled in the fire-resistant layer, elastic hoses are arranged in the round pipes, and elastic connecting parts are arranged between the elastic hoses and the round pipes.

Preferably, the round tube is a hard tube, and the elastic connecting part is a rubber strip.

Preferably, the fire-resistant layer is made of fire-resistant clay or fire-resistant cotton.

Preferably, a corrugated copper sheath is arranged between the fire-resistant layer and the inner protective layer.

Preferably, the inner protection layer sequentially comprises a fireproof insulation layer, an isolation layer and an insulation waterproof layer from inside to outside.

Preferably, the outer protective layer sequentially comprises an outer insulating layer, an outer waterproof layer, an outer fireproof layer and a wear-resistant layer from inside to outside.

The utility model provides an aerify type fire prevention flame retarded cable increases elastic hose in the pipe, makes the inside pressure increase after aerifing, when the cable takes place to melt, because powerful in the elastic hose, can press flame retardant gas to melting the department discharge rapidly.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural view of the round tube in a normal state of the present invention;

fig. 3 is a schematic structural view of the round tube in the inflated state of the present invention.

Detailed Description

As shown in fig. 1 and 2, an inflatable fireproof flame-retardant cable comprises a wire core 1, wherein an inner protection layer, a flame retardant coating 2 and an outer protection layer are sequentially arranged outside the wire core 1, and the inflatable fireproof flame-retardant cable is characterized in that: a plurality of round tubes 3 are filled in the fire-resistant layer 2, elastic hoses 4 are arranged in the round tubes 3, and elastic connecting parts 5 are arranged between the elastic hoses 4 and the round tubes 3.

Preferably, the round tube 3 is a hard tube, and the elastic connecting part 5 is a rubber strip.

Preferably, the fire-resistant layer 2 is made of fire-resistant clay or fire-resistant cotton.

Preferably, a corrugated copper sheath 6 is arranged between the fire-resistant layer 2 and the inner protective layer.

Preferably, the inner protection layer sequentially comprises a fireproof insulation layer 7, an isolation layer 8 and an insulation waterproof layer 9 from inside to outside.

Preferably, the outer protective layer sequentially comprises an outer insulating layer 10, an outer waterproof layer 11, an outer fireproof layer 10 and a wear-resistant layer 11 from inside to outside.

When the flexible pipe is used, as shown in fig. 3, after inflation, the flexible pipe deforms and extrudes the elastic connecting part 5, so that the internal pressure is high, and when the cable is fused, the flame-retardant gas can be rapidly pressed to the fused part to be discharged due to the high pressure in the flexible pipe.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
