Fire extinguishing device for expanded polystyrene

Abstract

The invention discloses a fire extinguishing device for expanded polystyrene, and belongs to the technical field of fire fighting equipment. The fire extinguishing device comprises an induction mechanism and a fire extinguishing mechanism, wherein the induction mechanism comprises a sliding plate, a sliding cavity and a platform with an open top and a hollow interior. The sliding plate is vertically and slidably connected in the platform. The fire extinguishing mechanism comprises a support frame, a motor, a fire extinguishing cover and a pulley rotatably connected to the top of the support frame. The pulley is wound with a rope, and one end of the rope is fixedly connected to the top of the fire extinguishing cover. The fire extinguishing cover is used for covering the expanded polystyrene, the motor comprises a driving shaft, the driving shaft is fixedly connected with the other end of the rope, and a conducting loop is formed among the motor, a first carbon rod pole and a second carbon rod pole. The fire extinguishing cover can cover the expanded polystyrene on fire and can extinguish the fire quickly.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a plastic foam fire extinguishing device. Background technique [0002] Plastic foam, it is a chemical material, the full name of polystyrene foam (Expanded Polystyrene, referred to as EPS). Due to its firmness, shock absorption, low moisture absorption, easy molding, good water resistance, heat insulation and low price, plastic foam is widely used in the fields of packaging, heat preservation, shock absorption and heat insulation, and is the most widely used in the world today. One of the wide range of plastics. [0003] The foam material formed after polystyrene foaming is greatly reduced in density and the area in contact with air per unit mass is greatly increased, so it will become easier to catch fire. Once it catches fire, the burning speed is extremely fast, and a large amount of Toxic and dense smoke, traditional fire extinguishing methods cannot effect...

AI Technical Summary

Problems solved by technology

[0003] The foam material formed after polystyrene foaming is greatly reduced in density and the area in contact with air per unit mass is greatly increased, so it will become easier to catch fire. Once it catches fire, the burning speed is extremely fast, and a large amount of Toxic and dense smoke, traditional fire extinguishing methods cannot effectively extinguish the fire, and the toxic and dense smoke produced will also cause harm to the human body, making it difficult to extinguish the fire. Quickly extinguish the fire, the fire will spread quickly
