Embodiment 1

[0038] An embodiment of the present invention discloses a fire extinguishing method, specifically, the unmanned aerial vehicle carries an airborne fire extinguishing bomb to perform a fire extinguishing task, wherein the structure of the airborne fire extinguishing bomb adopted is as follows Figures 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 monitors in real time whether an ignition time signal is received.

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

Embodiment 2

[0057] Yet another specific embodiment of the present invention discloses the airborne fire extinguishing bomb in Embodiment 1, and the drone carries the airborne fire extinguishing bomb in this embodiment to perform fire extinguishing 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 push the fire extinguishing bomb to fly; the spraying device 2 is filled with 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 spraying device 2 to spray the fire extinguishing agent 27.

[0058] In this embodiment, the spraying device 2 includes a spraying casing 21, an inner container 22 and a powder colum...

Abstract

The invention relates to an airborne fire extinguishing bomb and a fire extinguishing method, belonging to the technical field of fire extinguishing bombs, and solves the problems of poor safety, low control precision, high cost and high residual rate of fire extinguishing agent in existing fire extinguishing bomb products. The airborne fire extinguishing bomb includes a power unit, a spraying unit and a control unit, the power unit is used to propel the fire extinguishing bomb to fly, the spray unit is used to spray the fire extinguishing agent, and the control unit is used to control the ignition of the power unit and control the spraying unit to spray the fire extinguishing agent; The device includes a spraying shell, an inner container and a powder column. The inner container and the powder column 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 spray hole for spraying the fire extinguishing agent, and the spray hole It constitutes the spray channel of the fire extinguishing agent; the high temperature and high pressure gas generated after the powder is ignited acts on the fire extinguishing agent, and the fire extinguishing agent can break through the inner tank and spray out through the spray hole. In the fire extinguishing and spraying process of the present invention, there are no killing fragments, the product safety is high, and the agglomeration rate and remaining rate of the fire extinguishing agent are significantly 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. Utilizing the maneuverability and flexibility of flying platforms such as drones or helicopters, it is possible to approach fires at close range , 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] Existing fire extinguishing bomb products both at home and abroad at present include the following: (1) a kind of airborne fire extinguishing bomb, which is detonated in the interior by the center charge column and annular charge inside the fire extinguishing b...
