Problems solved by technology

Due to the strong updraft and turbulence over the fire site, the fire extinguishing agent was dispersed by the strong high-temperature airflow, and very little fire extinguishing agent fell on the canopy, so the fire extinguishing effect was not good.
In addition, according to the search, the air-dropped fire extinguishing bombs mentioned in some existing technical materials all use striker percussion type ground detonation or open flame ignition detonation, which cannot carry out fire extinguishing operations well at the height of tree crowns

Embodiment 1

[0018] Example 1: Combining figure 1 , the fire extinguishing bomb is made up of the fire extinguishing agent chamber at the front and the umbrella chamber at the rear, the detonating explosive 29 is located at the center of the fire extinguishing agent chamber, and is connected horizontally with the detonating detonator 31, and the fire extinguishing agent 28 is located around the detonating explosive 29 and surrounded by the shell 27, the control Circuit 40 is positioned on connecting ring 39, and connecting ring 39 links to each other with priming detonator 29 and umbrella storehouse body 32 by threaded connection, and temperature sensor 26 is positioned at cartridge case 27 front ends, and umbrella storehouse links to each other with fire extinguishing agent storehouse by threaded connection, and parachute throwing device is connected by hanger. cable 37, hook 16, spring leaf 17 and rear end cover 14, the hook 16 is threadedly connected with the rear end cover 14 and spring...

Embodiment 2

[0019] Embodiment 2: Combination figure 1 , the following device is installed in the fire extinguishing bomb described in Embodiment 1. The thermal sensors 30 are arranged in a ring on the cylinder of the bullet case 27, the sensor is connected to the bullet control circuit 40 through a wire 41, and the parachute power adjustment device is located at the bottom of the parachute chamber body , driven by two parallel motors 36 through coupling 35 to form the reel 34, the parachute umbrella rope is positioned in the guide groove of the reel 34, the reel 34 links to each other with the umbrella bin body 32 by the bearing 33. During the descending process of the fire extinguishing bullet, the thermal sensor 30 sends the signal to the control circuit 40 by sensing the temperature difference around the bullet. Pull the parachute cord to adjust the falling trajectory of the bullet so that it can fall directly above the fire scene, and complete the fire extinguishing operation more acc...

Embodiment 3

[0020] Example Three: Combining figure 2 and image 3 , on the basis of the original fire extinguishing bomb, use the fire extinguishing bomb as the bullet 6 and design the shell and its ejection device to form the mother bomb. The central axis 18 in the center is connected, and the storage magazine is mainly composed of a cutting cable 1, an electric detonator 2, a bayonet pin 3, a protective cover 4, an ejection device 5, a bullet 6, an annular clamping plate 7, a mother bullet control circuit 8, and a mother bullet casing 9 , spring 10, the cutting cable 1 is located in the ring-shaped groove of the front end and the rear end of the mother bullet casing 9 and is connected with the electric detonator 2, and the protective cover 4 is located at the front end of the storage magazine and is threadedly connected with the central axis 18, and the cutting cable 1 and the bullet The front end temperature sensor 26 is separated, and the ejection device 5 is located at the center o...

Abstract

The invention relates to a forest fire extinguishing device, which comprises a fire extinguishing agent bin and a parachute bin. A micro-explosion dispersion device is arranged at a central position of the fire extinguishing agent bin; the periphery of the micro-explosion dispersion device is provided with the fire extinguishing agent; the periphery of the fire extinguishing agent is encapsulatedwith a cartridge case which is connected with the parachute bin; a temperature sensor and a control circuit are also arranged in a fire extinguishing bomb, wherein the temperature sensor and the micro-explosion dispersion device are connected with the control circuit through leads respectively; the fire extinguishing agent bin is a primary functional bin; and a parachute slows down the descent speed of the fire extinguishing bomb so that the fire extinguishing bomb descending slowly feeds temperature data reaching a set threshold back to the control circuit when landing on the upper part of the flame of a crown fire in combination with the temperature sensor, the micro-explosion dispersion device and a temperature control system of the micro-explosion dispersion device, and then the control circuit controls the micro-explosion dispersion device to generate an explosion to disperse the fire extinguishing agent, thereby highly-efficiency extinguishing the crown fire in a short range.

Description

(1) Technical field [0001] The invention relates to a forest fire extinguishing device, more specifically to an intelligent control superfine dry powder fire extinguishing aerial bomb mainly used for extinguishing forest canopy fires, and belongs to the technical field of fire protection. (2) Background technology [0002] Forest fire is a serious worldwide natural disaster, which has caused immeasurable losses to human resources and the environment. It can bring about soil erosion, land desertification, burn down forest plant resources, endanger wild animals, cause air pollution, and threaten the safety of people's lives and property. At the scene of a forest fire, the first fires are often dwarf bushes and ground vegetation, which are called ground fires. When the ground fire is accompanied by strong winds, or encounters vines and low-hanging branches on the trunk, the fire will rise to the crown of the tree and become a crown fire. The fire takes advantage of the wind, ...
