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

Example Embodiment

[0018] Example 1: Combination figure 1 The fire extinguishing bomb is composed of a fire extinguishing agent warehouse at the front and an umbrella warehouse at the rear. The detonating agent 29 is located in the center of the fire extinguishing agent warehouse and connected horizontally with the detonating detonator 31. The fire extinguishing agent 28 is located around the detonating agent 29 and is surrounded by the cartridge case 27. The circuit 40 is located on the connecting ring 39. The connecting ring 39 is connected to the detonator 29 and the umbrella bin body 32 through a threaded connection. The temperature sensor 26 is located at the front end of the cartridge case 27. The umbrella bin is connected to the fire extinguishing agent bin through a threaded connection. The cable 37, the hook 16, the spring sheet 17 and the rear end cover 14 are composed of the hook 16 and the rear end cover 14 and the spring sheet 17 in threaded connection. The fire extinguishing bomb para...

Example Embodiment

[0019] Embodiment 2: Combination figure 1 The following devices are installed in the fire extinguishing bomb described in the first embodiment. The thermal sensors 30 are arranged in a circular arrangement on the cylindrical surface 27 of the bullet shell. The sensors are connected to the bullet control circuit 40 through wires 41. The umbrella power adjusting device is located at the bottom of the umbrella bin body. It is composed of two parallel motors 36 driving the reel 34 through the coupling 35. The parachute parachute line is located in the guide groove of the reel 34, and the reel 34 is connected to the umbrella bin body 32 through the bearing 33. In the process of the fire extinguishing bomb being opened and lowered, the thermal sensor 30 sends a signal to the control circuit 40 by sensing the temperature difference around the bullet. After the control circuit 40 analyzes and processes it, it sends a control signal to the drive motor 36 to make the motor 36 move forward ...

Example Embodiment

[0020] Example 3: Combination figure 2 with image 3 , On the basis of the original fire-fighting bomb, the fire-fighting bomb is used as the bullet 6 and the shell and its ejection device are designed to form the mother bomb. The mother bomb is composed of the front storage bin and the rear umbrella bin, both of which are located in the storage bin The central axis 18 is connected, and the magazine is mainly composed of a cutting cord 1, an electric detonator 2, a bayonet 3, a protective cover 4, an ejection device 5, a bullet 6, a ring card 7, a mother bullet control circuit 8, and a mother bullet shell 9 , Spring 10, the cutting cable 1 is located in the annular slot at the front and rear of the mother bomb shell 9 and connected with the electric detonator 2, the protective cover 4 is located at the front end of the magazine and the central shaft 18 is threaded to connect the cutting cable 1 and the bullet The front-end temperature sensor 26 is separated, the ejection device...

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, ...
