[0032] Embodiment 1:

[0033] As shown in Figure 1 Figure , a millimeter-wave ground ranging automatic detonation fire extinguishing device includes the fire extinguishing bomb 2 and the unmanned aerial vehicle 1, and the fire extinguishing bomb is mounted on the hook of the unmanned aerial vehicle.

[0034] The fire extinguishing bomb 2 includes: a bomb body 8, an extension rod 7, a sling component, a control component, a speed measuring device, a bottom cover 13, a ranging device, and a gas detonation device 11.

[0035] The bomb body is designed to be spherical, generally ellipsoidal, and has a receiving cavity; an upper mounting hole is provided at the top of the bomb body for mounting the sling component, and a lower mounting hole is provided at the bottom of the bomb body; dry powder fire extinguishing agent is filled into the receiving cavity through the lower mounting hole; the sling component includes a sling 3, a sling base 5, and a load-bearing fixing cover 6. A limiting groove is provided in the upper mounting hole, the sling base is installed in the limiting groove, and the sling base is rotatably installed on the extension rod with its own thread. The sling is fixed on the sling base and the top of the sling extends out of the bomb body; the load-bearing fixing cover is used to lock the sling base in the limiting groove.

[0036] The extension rod is arranged in the receiving cavity; an installation groove is provided at the bottom of the extension rod; the sling component is arranged at the top of the bomb body and is connected to the top of the extension rod; the control component is arranged in the installation groove; the speed measuring device is arranged on the control component; the gas detonation device is arranged in the installation groove; the gas detonation device is connected to the control component; the bottom cover is arranged at the bottom of the bomb body for sealing the mounting hole; the ranging device is arranged in the installation cavity and is connected to the bottom cover; the ranging device is connected to the control component. The control component further includes a power switch 4, the power switch is arranged on the sling component, the power switch is connected to the main control board through a connecting wire, and the connecting wire penetrates through the extension rod.

[0037] In some embodiments, the control component includes a battery 9 and a main control board 10. The battery is fixed in the installation groove by a buckle, and the main control board and the gas detonation module are sequentially installed in the installation groove and fixed by screws.

[0038] In some embodiments, the speed measuring device is an acceleration measurement module for measuring the acceleration when the bomb body is in free fall. The ranging device is a millimeter radar module 12 for measuring the distance between the bomb body and the ground.

[0039] Figure 1 The fire extinguishing bomb and the unmanned aerial vehicle shown in Figure are two different devices. When not in use, the two devices are in a separated state, and the fire extinguishing bomb is in a power-off state.

[0040] When in use, the fire extinguishing bomb is mounted on the hook of the unmanned aerial vehicle, as shown in Figure 1as shown

[0041] Figure 4 The power switch of the fire extinguishing bomb, the millimeter-wave radar module, and the gas detonation module are connected to the main control module through cables and are powered by a battery.

[0042] Figure 3 The usage method is as follows:

[0043] Before the drone takes off, hang the fire extinguishing bomb on the hook of the drone.

[0044] Turn on the power switch of the fire extinguishing bomb to energize the fire extinguishing bomb (powered by a battery), so that the main control module and the millimeter-wave radar module are energized;

[0045] Start the drone, and the drone carrying the bomb flies over the fire source.

[0046] Control the drone to fly to a position more than 30 meters above the ground vertically at the fire extinguishing point. And the fire extinguishing bomb falls freely vertically downward to the ground.

[0047] The hook of the drone disengages, and the fire extinguishing bomb falls freely.

[0048] When the acceleration of gravity reaches 9.8 m / s², the main control board starts the millimeter-wave radar module to detect the ground height.

[0049] During the free fall of the fire extinguishing bomb, the height between the fire extinguishing bomb and the ground is detected in real time. After the fire extinguishing bomb reaches the preset height (3 - 5 meters), the main control board immediately starts the gas detonation module.

[0050] After the gas detonation device is started, a large amount of gas is quickly filled into the bomb body, causing the bomb body to rupture, and the dry powder in the bomb body covers the fire source, achieving the effect of extinguishing the fire.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
