Description

Technical Field

[0001] The utility model relates to the application of drone technology in the field of fire fighting and fire extinguishing, in particular to a water-based fire extinguishing bomb. Background Art

[0002] In recent years, drone technology has gradually matured and has been widely used in various fields, including forest fire fighting and urban fire fighting. For example, in complex mountainous areas, suburban wilderness and some special occasions in cities, if the initial fire source is found, it is difficult for personnel and equipment to quickly go to the firefighting site. Using drones carrying fire extinguishing bombs, flying over it and dropping fire extinguishing bombs to extinguish the fire can effectively control the fire.

[0003] When using traditional fire extinguishing bombs, it is found that the thrown fire extinguishing bombs are prone to posture changes, the throwing accuracy is low, and the fire extinguishing effect is not ideal. Therefore, it is necessary to design a fire extinguishing bomb with small posture changes and good fire extinguishing effect. Utility Model Content

[0007] The water-based fire-extinguishing bomb body has a circumferentially equiangular petal shape;

[0008] The water-based fire-extinguishing bomb body has a water drop shape.

[0009] Preferably, the water-based fire extinguishing bomb joint is melted at the opening of the water-based fire extinguishing bomb body by internal and external pressure to ensure the strength of the pressure-melted interface, thereby improving the load-bearing performance of the water-based fire extinguishing bomb body.

[0010] Preferably, the water-based fire-extinguishing bomb joint includes a sealing cover hanging ring, a joint thread sealing cover, a bomb body thread stop valve seat and a stop valve;

[0011] It also includes a casting wire rope that is circumferentially wound and fixed at the annular notch of the joint thread sealing cover, and the casting wire rope is pulled out from the opposite side of the annular notch;

[0012] A sealing cover hanging ring is pressed onto the joint thread sealing cover; and a resiliently sealed stop valve is pressed onto the elastic body thread stop valve seat.

[0013] Preferably, the joint threaded sealing cover is screwed to the elastic body threaded stop valve seat via threads.

[0014] Preferably, a ring hole at one end of the sealing cover hanging ring is hung on the casting wire hanging rope.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The designed water-based fire-extinguishing bomb body has a water-drop shape, which makes the falling posture of the water-based fire-extinguishing bomb stable when it is thrown, and can improve the accuracy of throwing;

[0018] 2. Through the built-in stop valve seat, after the water-based fire extinguishing agent is loaded, the fire extinguishing agent is prevented from overflowing, and a certain amount of air is left inside to maintain a certain air pressure inside. When the water-based fire extinguishing bomb is thrown and landed, the water-based fire extinguishing solvent explodes in a wider range;

[0019] 3. The body of the water-based fire-extinguishing bomb is designed to be in the shape of petals with equal angles in the circumferential direction, with the number of petals ≥ 4, so that the water-based fire-extinguishing bomb can explode in the circumferential direction when it hits the ground, and the water-based fire extinguishing agent can be evenly spread to improve the fire extinguishing effect.
