Embodiment 1

[0038] An embodiment of the present invention discloses a fire extinguishing method. Specifically, a drone carries an airborne fire extinguishing bomb to perform a fire extinguishing task. The structure of the airborne fire extinguishing bomb is as follows: Figure 1 to 2 As shown, the working process of fire extinguishing is as follows image 3 As shown, the fire extinguishing method includes the following steps:

[0039] In the first step, the control device 3 is powered on and started, and it is monitored in real time whether there is an ignition time signal.

[0040] After the drone finds the target of the fire point, the onboard control system of the drone calculates the ignition time of the fire extinguishing bomb based on the location information of the fire point and the UAV platform, combined with the external ballistic information of the fire extinguishing bomb, and sends the ignition time signal to the fire extinguishing bomb The power supply signal is sent to the control...

Embodiment 2

[0057] Another specific embodiment of the present invention discloses the airborne fire extinguishing bomb in the first embodiment, and the drone carries the airborne fire extinguishing bomb in this embodiment to perform fire fighting tasks. Such as Figure 1 to Figure 2 As shown, the airborne fire extinguishing bomb includes a power device 1, a spray device 2 and a control device 3. The power device 1 and the spray device 2 are connected by threads, and the control device 3 is installed and fixed on the spray device 2. Among them, the power unit 1 is used to promote the flight of fire extinguishing bombs; the spray device 2 is filled with a fire extinguishing agent 27 and can spray the fire extinguishing agent 27; the control device 3 is used to control the ignition of the power unit 1 and control the spray device 2 to spray the fire extinguishing agent 27.

[0058] In this embodiment, the spray device 2 includes a spray housing 21, an inner container 22 and a grain 24. The inne...

Abstract

The invention relates to an onboard fire extinguishing bomb and a fire extinguishing method, belongs to the technical field of fire extinguishing bombs, and solves the problems of poor product safety,low control precision, high cost and high residual rate of a fire extinguishing agent of an existing fire extinguishing bomb. The airborne fire extinguishing bomb comprises a power device, a sprayingdevice and a control device, wherein the power device is used for pushing the fire extinguishing bomb to fly, the spraying device is used for spraying a fire extinguishing agent, and the control device is used for controlling ignition of the power device and controlling the spraying device to spray the fire extinguishing agent; the spraying device comprises a spraying shell, an inner container and a grain, the inner container and the grain are arranged inside the spraying shell, and the inner container is used for filling the fire extinguishing agent; the spraying shell is provided with a spraying hole for spraying the fire extinguishing agent, and the spraying hole forms a spraying channel for the fire extinguishing agent; and the high-temperature and high-pressure gas generated after the grain is ignited acts on the fire extinguishing agent, and the fire extinguishing agent can puncture the inner container and be sprayed out through the spraying hole. According to the onboard fire extinguishing bomb and the fire extinguishing method, no toxic fragment is generated in the fire extinguishing and spraying process, the product safety is high, and the caking rate and the residual rate of the fire extinguishing agent are obviously reduced.

Description

Technical field [0001] The invention relates to the technical field of fire extinguishing bombs, in particular to an airborne fire extinguishing bomb and a fire extinguishing method. Background technique [0002] Long-distance fire fighting under complex backgrounds, such as super high-rise building fires and cliff fires in forest fires, has always been a difficult problem in the field of fire rescue. Using the mobile and flexible characteristics of flying platforms such as drones or helicopters, close proximity to the fire , By launching fire extinguishing bombs, the fire can be accurately suppressed at the first time, and the purpose of controlling the spread of the fire can be achieved. [0003] At present, the existing fire extinguishing bomb products at home and abroad include the following: (1) An airborne fire extinguishing bomb, which is detonated by the central grain and annular charge inside the fire bomb to release the fire extinguishing agent. The release process is ac...
