Building fresh air exhaust pipeline temperature self-checking, blocking, fireproof and flame-retardant system

Abstract

The invention discloses a building fresh air exhaust pipeline temperature self-checking, blocking, fireproof and flame-retardant system. The system comprises a pipeline body, a guide pipe, vent holes, rotating shafts and side guide rails, telescopic rods are fixedly mounted on the outer walls of the left side and the right side of the pipeline body, kerosene liquid is arranged in the telescopic rods, and an isolation net is fixedly mounted on the inner wall of the pipeline body. Connecting pieces and connecting rods are rotationally mounted at the middles and the ends of the outer walls of output shafts of the telescopic rods correspondingly, the ends of the connecting pieces are hinged to one ends of transverse shafts, and a liquid outlet head is arranged at the bottom of a liquid outlet pipe and located in the pipeline body. According to the building fresh air exhaust pipeline temperature self-checking, blocking, fireproof and flame-retardant system, spacing distribution in the pipeline is realized, under the temperature change effect of a fire source, cooling of a fire source and oxygen isolation type fire extinguishing can be performed, smoke gathering during fire extinguishing cannot be caused, and continuous and uninterrupted emission of smoke is performed.

Description

technical field [0001] The invention relates to the technical field related to green building safety, in particular to a temperature self-checking and blocking fire-proof and flame-retardant system of a building fresh air exhaust duct. Background technique [0002] The building fresh air duct is installed in a large space building facility to carry out air guidance and exhaust facilities for the indoor and outdoor environment of the building. The regulation and circulation of the building enable people living in the room to breathe clean and fresh air in their long-term life, and the laying and setting of fresh air ducts can stably discharge and subsequently effectively purify the dirty gas in the building. [0003] However, the existing building fresh air ducts have the following problems in use: [0004] 1. The laying and installation of pipelines can only be done with conventional ventilation settings. When a fire occurs, the pipeline cannot be blocked and blocked, which...

Problems solved by technology

[0007] The purpose of the present invention is to provide a building fresh air exhaust pipe temperature self-checking barrier fire prevention and flame retardant system to solve the above background technology. It is proposed that the existing building fresh air pipe laying and installation can only carry out conventional ventilation settings, in case of fire etc. When the fire occurs, it is not possible to block and block the pipeline, which will cause the spread of the fire and aggravate the fire situation. When the fire occurs, timely and accurate fire source blocking cannot be carried out. When the fire source is blocked and isolated, it is impossible to Conventional ventilation and discharge of dense smoke by-products of the fire source will easily lead to a large amount of dense smoke gathering indoors at the fire source site, affecting the visibility of the indoor environment of the building, and causing subsequent fire fighting and rescue problems at the fire source site
