Intelligent early-warning fireproof and explosion-proof blanket as well as preparation method and application thereof

Abstract

The invention discloses an intelligent early-warning fireproof and explosion-proof blanket. The cable comprises a fireproof and explosion-proof blanket, a high-voltage cable joint, a first through hole, a second through hole, a fireproof and explosion-proof inner layer, a fabric outer surface layer, a sealing ring, a blocking bag, a temperature sensor, a pressure sensor, a controller, a position sensing layer and a position sensor, and the fireproof and explosion-proof blanket wraps the outer surface of the periphery of the high-voltage cable joint; a fireproof and explosion-proof inner layeris arranged on the outer side of the position sensing layer, a fabric outer surface layer is arranged on the side, away from the position sensing layer, of the fireproof and explosion-proof inner layer, and a plurality of position sensors are arranged on the position sensing layer. The fire disaster is detected through the smoke sensor, the detection accuracy is improved, meanwhile, the working intensity of maintenance and rescue workers is reduced, the working efficiency of the device is improved, the maintenance and rescue workers are reasonably arranged, the rescue speed is increased, and damage to a cable connector is reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of an intelligent fireproof and explosion-proof blanket, in particular to an intelligent early warning fireproof and explosion-proof blanket and its preparation method and application.

Problems solved by technology

[0002] At present, with the rapid development of the domestic economy, electric power industry cables are widely used in many fields. Due to the limitation of the number of cable tunnels at this stage, it is often the case that the cable intermediate joint is installed together with other operating cable lines, that is, the State Grid The cables referred to by the company are used in mixed trenches, and the intermediate joints are affected by human factors, construction, and operating environments, which will inevitably cause breakdown or explosion accidents. The energy released by cable accidents is enough to damage the surrounding cable lines and facilities. and personnel injury, and even lead to secondary accidents. The protection of the cable joints in the market is mainly the use of glass fiber reinforced plastic cable joint protection boxes. In the cable joints, if the cable joints are in poor contact during installation, it is very easy to Electric sparks are generated, and the electric sparks contact with oxygen ions in the air, which will ignite the cable and cause a fire. Once a fire occurs, the ordinary cable will continue the fire to all connected equipment and every corner of the building, and at the same time generate A large amount of toxic smoke increases fire losses and brings difficulties to rescue work, so the problem of cable fire protection is particularly important

[0003] However, in the prior art, the fire and explosion-proof blanket cannot accurately detect the occurrence of a fire and the specific location of the spark at the cable joint. At the same time, when a fire occurs, it cannot send a fire signal to the maintenance and rescue personnel in time.
