Description

Technical Field

[0001] The invention belongs to the technical field of fire extinguishing devices, and in particular relates to a backpack gas-mounted fire extinguishing device. Background Art

[0002] Conventional fire extinguishers such as foam are used to extinguish fires in small tanks and cylinders such as wine cans and oil pans. Although the fire can be extinguished, it is easy to cause oil, wine and other substances to splash, causing the fire to expand again and may even threaten the lives of the firefighters. The main reason is the instability of the foam and the impact during the fire extinguishing process, which makes it impossible for the fire extinguishing agent to completely cover the surface of the small tank and cylinder, and cannot play an insulating and heat-insulating role. The use of such fire extinguishing agents in the early stage of fire extinguishing may also cause the occurrence of bangs and re-ignition. Moreover, once the fire of the tank or cylinder is large, personnel will not be able to get close to the fire, and it is difficult to spray the fire extinguishing gas, powder, etc. to the source of the fire. The fire cannot be controlled in time, posing a threat to personal and property safety. For wine cans, the use of fire extinguishing materials such as foam and powder will also lead to a waste of raw materials, greatly increasing production costs.

[0027] A firefighting backpack, in which a firefighting gas cylinder 6 for storing inert firefighting gas is arranged for firefighting;

[0028] The nozzle 2 is telescopically adjustable in length, and the nozzle 2 extends into the firefighting backpack and is connected to the outlet of the fire-extinguishing gas cylinder 6. The nozzle 2 is provided with a regulating component for controlling the flow rate of the inert fire-extinguishing gas;

[0029] The isolation protective cover 1 is expandable and retractable. The isolation protective cover 1 is arranged at the end of the nozzle 2 away from the firefighting backpack. The end of the nozzle 2 passes through the isolation protective cover 1. When extinguishing a fire, the isolation protective cover 1 is arranged on the fire point.

[0030] The purpose of the present invention is to provide a backpack gas hood fire extinguishing device, which aims to solve the problems that existing fire extinguishers are difficult to extinguish fires in tanks and cylinders such as wine tanks and oil pans, cannot control the fire from the source in a timely and rapid manner, and are prone to causing injuries to personnel and the spread of fire. The fire source is isolated from personnel so that the fire source is in a relatively isolated environment to prevent the occurrence of dangerous phenomena such as splashing and explosions. The fire extinguishing material uses inert fire extinguishing gas, and the fire is extinguished without destroying the original wine and other substances, reducing cost expenditure and waste of raw materials.

[0031] The invention discloses a backpack type gas hood fire extinguishing device, which is mainly used for extinguishing fire of wine tanks or oil tanks containing flammable liquids. When in use, the operator carries the fire extinguishing backpack on his back, and then covers the burning tank with an isolation protective cover 1, and then sprays inert fire extinguishing gas to the burning liquid in the covered tank through a nozzle 2 to extinguish the fire, which can not only isolate the fire source to avoid personal injury caused by splashing of wine, oil and other substances, but also prevent dangerous phenomena such as flashover and re-ignition during the fire extinguishing process. The fire extinguishing gas cylinder 6 is filled with inert fire extinguishing gas, which is cheap, has stable physical properties, and has no extinguishing effect. The fire extinguishing effect is good, the fire extinguishing efficiency is high, and the quality of materials such as wine and oil is not damaged. For fires caused by factors such as static electricity on wine tanks and fires on oil pans, the original material components will not be destroyed after the fire is extinguished by the present invention, thus avoiding unnecessary waste; the setting of the isolation protection group cover can block the mouth of the burning tank, avoiding the splashing of the burning medium outward, and playing a protective role for the operator. At the same time, the nozzle 2 can be retracted, and the rescue personnel do not need to be close to the fire source. With the isolation protection cover 1, the fire source can be accurately extinguished at a long distance, effectively reducing the possibility of the fire source re-igniting, and realizing rapid and accurate extinguishing of the fire source. The present invention has a simple structure and flexible operation. It can isolate and cover fires such as fires on wine tanks, fires on oil pans, and fires caused by gas tank leakage, and can avoid the dangers of splashing, flashover, and re-ignition that may occur during the fire extinguishing process. The fire source is accurately and quickly extinguished under the premise of ensuring the safety of the fire extinguishers, which greatly improves the efficiency of fire extinguishing of small tanks and cylinders and the safety of fire extinguishing.
