FIRE EXTINGUISHING BOMB TECHNICAL FIELD

[0001] The utility model relates to the field of fire extinguishing devices, in particular to a fire extinguishing bomb.

BACKGROUND

[0002] At present, the situation of forest fire prevention in China is very severe. In addition to traditional fire fighting tools, fire extinguishing bombs are often used in fighting forest and grassland fires. Generally, the filler of fire extinguishing bombs is mostly powder fire extinguishing agent and is thrown manually. Compared with powder fire extinguishing agents, water-based fire extinguishing agents have better fire extinguishing effects.

SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a fire extinguishing bomb, which transfers the water-based fire extinguishing bomb on a drone, and can achieve fire extinguishing operations at higher altitudes in forest fire prevention more efficiently and conveniently, so as to solve a plurality of defects described above resulted from the prior art.

[0004] In order to achieve the above object, the utility model provides the following technical solutions: a fire extinguishing bomb, comprising a left coaxial anti-propeller, an airborne beam, a remote control device, a right coaxial anti-propeller, a landing foot, throwing machine arms, an electric shock detonating device and a water-based fire extinguishing bomb, wherein the left coaxial anti-propeller and the right coaxial anti-propeller are symmetrically provided at the left and right ends of the airborne beam, the landing foot is fixedly provided under the airborne beam, the remote control device is fixedly provided in the middle of the airborne beam, the throwing machine arms are provided symmetrically at both ends of the airborne beam, the water-based fire extinguishing bomb is embedded in the e throwing machine arms, and the electric shock detonating device is connected between the remote control device and the water-based fire extinguishing bomb.

[0005] Preferably, there are three landing feet, which are fixedly provided on the airborne beam in an equilateral triangle structure position.

[0006] Preferably, the throwing machine arm comprises a fixed shaft, a rotating shaft, a throwing arm and a fire extinguishing bomb grip groove, the fixed shaft is fixedly provided on the airborne beam, the throwing machine arms are connected on the fixed shaft through the rotating shaft, and the fire extinguishing bomb grip groove is fixedly provided on the throwing machine arms.

[0007] Preferably, the water-based fire extinguishing bomb comprises a shell, an explosive barrel, a water-based high-concentration fire extinguishing agent filling layer and a delay fuze, the shell is a spherical structure, the explosive barrel is provided at the center of the shell, the water-based high-concentration fire extinguishing agent filling layer is filled between the shell and the explosive barrel, one end of the delay fuze is connected to the explosive barrel, and the other end thereof is connected to an electric shock detonating device.

[0008] The beneficial effect of adopting the above technical solution is as follows: the fire extinguishing bomb with the structure of the utility model transfers the water-based fire extinguishing bomb on a drone, and can achieve fire extinguishing operations at higher altitudes in forest fire prevention more efficiently and conveniently. There are three landing feet, which are fixedly provided on the airborne beam in an equilateral triangle structure position. The structure adopts the most stable equilateral triangle structure to achieve the purpose of landing stably when a drone is landing. The throwing machine arm comprises a fixed shaft, a rotating shaft, a throwing arm and a fire extinguishing bomb grip groove, the fixed shaft is fixedly provided on the airborne beam, the throwing machine arms are connected on the fixed shaft through the rotating shaft, and the fire extinguishing bomb grip groove is fixedly provided on the throwing machine arms. This structure can throw fire extinguishing bombs within 180 degrees of the horizontal plane, which increases the range of throwing bombs and the range of forest fire extinguishing. The fire extinguishing bomb grip groove is a hemispherical device. The structure is matched with the spherical fire extinguishing bomb and can stably fix the fire extinguishing bomb, which prevents the fire extinguishing bomb from slipping off. The water-based fire extinguishing bomb comprises a shell, an explosive barrel, a water-based high-concentration fire extinguishing agent filling layer and a delay fuze, the shell is a spherical structure, the explosive barrel is provided at the center of the shell, the water-based high-concentration fire extinguishing agent filling layer is filled between the shell and the explosive barrel, one end of the delay fuze is connected to the explosive barrel, and the other end thereof is connected to an electric shock detonating device. This structure can spray the fire extinguishing agent on a large area when the explosive barrel explodes, so as to achieve efficient fire extinguishing of forest fire points.
