Portable air and sand blasting forest fire extinguisher

Abstract

The invention relates to the technical field of forest fire extinguishment and grassland fire extinguishment, particularly discloses a portable air-blast and sand-blast forest fire extinguisher, and mainly aims to solve the problems of fire extinguishment of edge small kindling and combustion supporting of wind to central kindling in an existing wind power fire extinguishment technology. Mud and sand on the edge of a fire scene are smashed through the mud and sand excavating and smashing device of the portable blast sand blasting forest fire extinguisher, the mud and sand are sucked by a low-pressure air inlet of the centrifugal blower of the fire extinguisher main device, and mud and sand airflow is sprayed to a fire source after the mud and sand are pressurized by the fan, so that the fire extinguishing effect is achieved. According to the technical scheme, the lithium battery pack is adopted as energy power of the mud and sand digging and crushing device and the centrifugal fan device, so that the fire extinguisher is light and convenient, the fire extinguishing main material mud and sand are ensured to be locally and infinitely supplied, and high-pressure and high-speed mud and sand jet flow can efficiently destroy and split a combustion layer of a fire source; the device is portable, efficient, energy-saving and environment-friendly.

Description

Technical Field

[0001] The invention belongs to the technical field of forest fire extinguishing and grassland fire extinguishing, in particular to the improvement of mountain forest and dam forest fire extinguishing technology. Background Art

[0002] Since humans learned to use fire, there has been a struggle with fire. Humans have invented many technologies to fight fire, such as water, carbon dioxide, dry powder, foam, etc., which are limited by the manufacture, transportation and use scenarios of fire extinguishing agents. For forest fires and grassland fires, especially mountain forest fires and forest fires on dams, there are no roads in the wilderness, and fire-fighting equipment and fire-extinguishing agents cannot be transported to the fire scene, which shows serious limitations. The portable air-blast sandblasting forest fire-fighting equipment of the present invention is particularly necessary. Summary of the invention

[0003] The object of the present invention is to provide a portable air-blast sandblasting forest fire extinguisher to solve the problems existing in the above-mentioned background technology.

[0004] The technical solution of the present invention includes three parts: a power battery, a mud and sand excavation device, and a mud and sand injection device. The structure and working principle of the mud and sand excavation device: The mud and sand excavation device works through a handheld motor. The operation of the motor drives the mud and sand excavation cutter disc to rotate at high speed. The cutter disc rotates to implement soil excavation and crushing. The excavated and crushed mud and sand are isolated under the cutter disc guard and then transported to the mud and sand injection device through the outlet. The structure and working principle of the mud and sand injection device: The mud and sand injection device consists of a sand suction pipe and a centrifugal high-pressure blower. The mud and sand in the excavation device storage device are sucked into the low-pressure air inlet of the centrifugal high-pressure turbine fan. After being pressurized by the blower, the mud and sand airflow is sprayed toward the fire source to achieve a fire extinguishing effect. The centrifugal high-pressure blower is handheld and can flexibly spray sand and soil for fire extinguishing. Power battery of the fire extinguisher: This technical solution uses a lithium battery pack as the energy source for the mud and sand excavation and crushing device and the centrifugal fan device.

[0005] The technical solution of the present invention realizes the lightness of the fire extinguisher, ensures the unlimited supply of mud and sand, the main fire extinguishing material, which is locally available, and has the technical effect that the high-pressure and high-speed mud and sand jet can efficiently destroy and split the combustion level of the fire source, and has the characteristics of portability, high efficiency, energy saving and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0007] Attached Figure 1 It is a schematic diagram of the structure of the present invention;

[0008] Attached Figure 2 It is a schematic diagram of the structure of the soil cutting disc of the mud and sand excavation device of the present invention;

[0009] In the figure, 1 and 2 are external power supplies; 3 is a handheld centrifugal high-pressure blower; 4 is a sand and soil suction pipe; 5 is a handheld soil cutting motor; 6 is a cutter head cover (the soil cutting cutter head is placed below); 7 is a cutter head cover; DETAILED DESCRIPTION

[0010] Person A carries a portable power source 2 and holds a soil cutting motor 5. The motor works and drives the surrounding Figure 2 The soil cutting disc cuts soil and gravel, and the cut soil and gravel are stored in the disc cover 7. Person B carries a portable power source 1 and holds a centrifugal high-pressure blower 3. When the centrifugal blower is working, the mud and sand in the disc cover are sucked into the sand suction pipe 4 by the low-pressure air inlet of the centrifugal high-pressure turbine blower. After being pressurized by the blower, the mud and sand airflow is sprayed toward the fire source, achieving a fire extinguishing effect.
