Description

Technical Field

[0001] The utility model relates to the technical field of dry powder fire extinguishing bombs, in particular to a dry powder fire extinguishing bomb used for a pulse air pressure spray water gun. Background Art

[0002] A pulse gun is a device that uses high-pressure gas to quickly spray objects, generating a powerful propulsion force through a pulse emission mechanism. It is widely used in firefighting, industrial cleaning, agriculture and other fields. It has versatility and precise control capabilities, and can adjust the spray pressure and range according to demand, providing efficient solutions. The pulse air pressure spray water gun produced by our company uses water mist to extinguish fires. It sprays 1 liter of water from the nozzle at a pressure of 2.5MPa. The effective range of the high-pressure water mist is nearly 20 meters, with a maximum diameter of 5 meters. It has the characteristics of atomization heat absorption, pulse impact, oxygen isolation, high fire extinguishing efficiency, and dust reduction and smoke exhaust. Quickly open the escape route and avoid danger quickly, and the interval between each water supply is less than or equal to 3 seconds. In addition to the functions introduced in the above information, the pulse gun can also launch fire extinguishing bombs (dry powder fire extinguishing bombs can also be thrown by hand, and manually pull the bracelet to throw them to the fire), and implement long-distance fire extinguishing at the fire scene, especially fire points on cliffs or fires on the outer walls of high-rise buildings, avoiding the problem that machinery and personnel cannot go up and implement fire extinguishing. At this time, fire extinguishing bombs can be launched to extinguish the fire, thus solving the problem of not being able to extinguish the fire from a distance. However, the long-term storage of the fire extinguishing bombs is prone to the invasion of the external environment, especially moisture, which affects the service life of the product. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A dry powder fire extinguishing bomb for a pulse air pressure spray water gun comprises a bomb body, a nozzle is provided on the top of the bomb body, a sealing plate is connected to the nozzle, the sealing plate is made of rubber, and a base is fixedly connected to the bottom of the bomb body.

[0006] As a further solution of the present invention: an isolation layer is fixedly connected to one side of the inner wall of the projectile, the isolation layer is made of rubber material, and explosives are arranged inside the projectile and on one side of the isolation layer.

[0007] As a further solution of the present invention: a fuse is provided on the side of the explosive close to the isolation layer, and the fuse passes through the side of the isolation layer away from the explosive and is connected to the pull ring; a dry powder fire extinguishing agent is placed inside the projectile.

[0008] As a further solution of the present invention: the elastic body is provided with an inner lining and an outer coating, and the order from the inside to the outside is the inner lining, the elastic body and the outer coating.

[0009] As a further solution of the present invention: the elastic body is made of aluminum alloy or stainless steel; the outer coating is a polyester coating; and the inner lining is made of rubber.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. During use, the sealing plate installed on the nozzle at the top of the projectile body effectively isolates the explosives and dry powder fire extinguishing agent in a confined space. This design prevents the impact of external moisture on the dry powder fire extinguishing agent, ensuring its effectiveness after long-term storage, and also reduces the risk of accidental triggering. At the same time, it ensures that both can be reliably activated when needed to achieve the best fire extinguishing effect. The confined space also helps maintain a stable internal environment, extending the service life of the product and ensuring the reliability and effectiveness of the equipment under extreme conditions.

[0012] 2. Insert the fire extinguishing bomb into the front barrel of the pulse gun, and then use the gas pressure of 2.5Mpa at the outlet of the pulse gun main valve body to push the dry powder fire extinguishing bomb out of the pulse gun barrel. The pull ring is fixed on the pulse gun in advance. At the moment the fire extinguishing bomb comes out of the muzzle, pull the fuse while delaying (the time length is adjustable) and flying along a parabola. Finally, it explodes above the stove according to the pre-set time. At this time, the area covered by the dry powder will not reignite and the fire can be extinguished.
