Description

Cable fire blanket

Technical Field

The invention relates to a cable fireproof blanket.

Background

At present, electricity plays an important role in the development of national economy and daily life of people, and the normal operation of a power system is a premise and guarantee for realizing the stable development of society. In the process of cable laying, a plurality of cables often share a cable trench, or a cable middle joint is installed with other running cable lines, in the actual power transmission process, because the inside of the cable generates heat in the high-voltage power transmission process, the poor contact of the cable joint generates breakdown or electric sparks, or is influenced by external open fire or high temperature, the normal work of the cable is threatened, and short circuit occurs easily,

When the circuit is broken, a serious fire disaster occurs. The fireproof function of the insulated cable in the current market is weaker, most of cable intermediate joints are subjected to waterproof treatment, the fire easily occurs when external fire or breakdown inside the cable occurs, and the normal work of the cable in the same ditch and the safety of the peripheral area are hardly guaranteed.

The invention is realized by the following measures:

a cable fireproof blanket comprises a rectangular blanket body, wherein one side of the upper surface of the blanket body is provided with a plurality of hook rings, the other side of the upper surface of the blanket body is provided with a plurality of strapping tapes, the blanket body is sequentially connected with a heat insulation outer layer, a fire extinguishing agent laying layer, a composite metal foil layer and a heat insulation inner layer in a stacking manner from top to bottom, the fire extinguishing agent laying layer comprises a superfine dry powder non-woven fabric bag and an aerosol non-woven fabric bag, superfine dry powder is filled in the superfine dry powder non-woven fabric bag, aerosol powder is filled in the aerosol non-woven fabric bag, a plurality of upper raised parts and lower recessed parts are arranged on the upper surface of the superfine dry powder non-woven fabric bag at intervals, a plurality of lower raised parts and upper recessed parts are arranged on the lower surface of the aerosol non-woven fabric bag at intervals, the superfine dry powder non-woven fabric bag and the aerosol non-woven, the lower bulge part of the aerosol non-woven fabric bag is tightly adhered and buckled with the lower concave part of the superfine dry powder non-woven fabric bag.

The heat insulation outer layer and the heat insulation inner layer are both ceramic silicon rubber and glass fiber composite cloth, and the surfaces of the heat insulation outer layer and the heat insulation inner layer are sprayed with nanometer heat insulation coatings.

The upper surface of the blanket body is close to one side of the hook ring, and the lower surface of the blanket body is close to one side of the strapping tape and is provided with a nylon magic tape.

The invention has the beneficial effects that: the cable is convenient to use, has better fire-resistant and high-temperature-resistant performance, is wound at the middle joint of the cable, and can ensure the normal work of the cable in the same ditch and the safety of the peripheral area even when an external fire disaster occurs or the cable is punctured internally to cause a fire disaster.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic cross-sectional structure of the present invention.

Wherein: 1 blanket body, 2 collude rings, 3 strapping, 4 nylon magic subsides, 5 thermal-insulated skin, 6 nanometer thermal-insulated coatings, 7 superfine dry powder non-woven cloth bags, 8 aerosol non-woven cloth bags, 9 composite metal foil layer, 10 thermal-insulated inlayers.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1 and 2, a cable fireproof blanket comprises a rectangular blanket body 1, wherein one side of the upper surface of the blanket body 1 is provided with a plurality of hook rings 2, the other side of the upper surface of the blanket body 1 is provided with a plurality of strapping tapes 3, the blanket body 1 is sequentially connected with a heat insulation outer layer 5, a fire extinguishing agent laying layer, a composite metal foil layer 9 and a heat insulation inner layer 10 in a stacking manner from top to bottom, the fire extinguishing agent laying layer comprises a superfine dry powder non-woven fabric bag 7 and an aerosol non-woven fabric bag 8, the superfine dry powder non-woven fabric bag 7 is filled with superfine dry powder, the aerosol non-woven fabric bag 8 is filled with aerosol powder, a plurality of upper raised parts and lower recessed parts are arranged on the upper surface of the superfine dry powder non-woven fabric bag 7 at intervals, a plurality of lower raised parts and upper recessed parts are arranged on the lower surface of the aerosol non-woven fabric bag 8 at intervals, the superfine dry powder non-woven fabric bag 7 and the aerosol non-woven fabric bag, the lower convex part of the aerosol non-woven fabric bag 8 is tightly buckled with the lower concave part of the superfine dry powder non-woven fabric bag 7.

The heat insulation outer layer 5 and the heat insulation inner layer 10 are both ceramic silicon rubber and glass fiber composite cloth, and the surfaces of the heat insulation outer layer 5 and the heat insulation inner layer 10 are sprayed with the nanometer heat insulation coating 6. One side that the upper surface of blanket body 1 is close to colluding ring 2 to and one side that the lower surface of blanket body 1 is close to strapping 3 is provided with nylon magic subsides 4.

During the use, with blanket body 1 parcel in cable joint department, wrap up the round back, pass the strapping 3 and collude ring 2 and tie tightly, nylon magic subsides 4 are pasted together, make more firm reliable of blanket body 1 parcel, avoid the strapping 3 pine after long-time to take off. The heat insulation outer layer 5 and the heat insulation inner layer 10 are both ceramic silicon rubber and glass fiber composite cloth, and have a strong fire-resistant and heat-insulating effect. The composite metal foil layer 9 can improve the strength of the blanket body 1, ensure that the blanket body 1 can not crack even if explosion occurs, and improve the safety and reliability. The upper raised part of the superfine dry powder non-woven bag 7 is tightly stuck and buckled with the upper sunken part of the aerosol non-woven bag 8, and the lower raised part of the aerosol non-woven bag 8 is tightly stuck and buckled with the lower sunken part of the superfine dry powder non-woven bag 7. Superfine dry powder non-woven cloth bag 7 and aerosol non-woven cloth bag 8 are overlapped in a staggered mode, so that the slippage of a fire extinguishing agent laying layer caused in the process of transporting or wrapping a cable can be prevented, the thickness of the fire extinguishing agent laying layer is guaranteed to be kept uniform all the time, the thickness of the fire extinguishing agent laying layer is prevented from being reduced, the situation that a thin place cannot play a fire extinguishing role is avoided, and the fire extinguishing agent laying layer becomes a breakthrough of a fire disaster. The nano heat insulation coating 6 improves the fire-resistant and heat-insulating effects of the blanket body 1.

The foregoing is only a preferred embodiment of this patent, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of this patent, and these modifications and substitutions should also be regarded as the protection scope of this patent.
