Embodiment 1

[0035] A specific embodiment of the present invention discloses a fire extinguishing bomb, which is suitable for unmanned aerial vehicles to extinguish fires. The unmanned aerial vehicle is equipped with the fire extinguishing bombs in this embodiment to perform fire extinguishing tasks. like Figure 1 to Figure 2 As shown, the fire extinguishing bomb includes a power unit 1, a spraying device 2 and a control device 3, the power unit 1 and the spraying device 2 are connected by threads, and the control device 3 is installed and fixed on the spraying 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.

[0036] In this embodiment, the spraying device 2 includes a spraying casing 21, a...

Embodiment 2

[0048] Yet another embodiment of the present invention discloses a fire extinguishing method based on the fire extinguishing bomb in Embodiment 1. The working process of fire extinguishing is as follows: image 3 shown, including the following steps:

[0049] 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.

[0050] 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 power supply signal is sent to the control device 3 of the fire extinguishing bomb. After the control device 3 of the fire extinguishing bomb receives the external power supply signal, it starts a self-che...

Abstract

The invention relates to a fire extinguishing bomb and a fire extinguishing method and belongs to the technical field of fire extinguishing bombs. The problems of poor safety, low control precision, high cost and high fire extinguishing agent surplus ratio of an existing fire extinguishing bomb product are solved. The fire extinguishing bomb comprises a power device, a spraying device and a control device, the power device is used for pushing flight of the fire extinguishing bomb, and the control device is used for controlling ignition of the power device and controlling the spraying device tospray a fire extinguishing agent; the spraying device comprises a spraying shell, a liner and a propellant grain, the liner and the propellant grain are arranged in the spraying shell, and the lineris used for being filled with the fire extinguishing agent; the spraying shell is provided with spraying holes for the fire extinguishing agent to be sprayed out of, and the spraying holes form a spray channel of the fire extinguishing agent; after the propellant grain is ignited, generated high-temperature and high-pressure gas is applied to the fire extinguishing agent so that the fire extinguishing agent can break through the liner and be released out of the fire extinguishing bomb from the spraying holes. According to the fire extinguishing bomb, in the spraying process, no harmful fragments are generated, the product safety is high, and the caking rate and surplus ratio of the fire extinguishing agent are obviously lowered.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing bombs, in particular to a 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 bomb to rel...
