Embodiment Construction

[0037] The following is attached Figure 1-5 The application is described in further detail.

[0038] see figure 1 , a fire extinguishing grenade, including a spherical grenade body 1 and a rotating frame 2 located at the lower end of the grenade body 1 .

[0039] see figure 1 with figure 2 The rotating frame 2 includes a rotating base 3 that stands on a flat ground that is prone to fire and a rotating platform 4 that is connected to the upper end of the rotating base 3 through a rotating shaft. Place the groove 5, and the rotating pallet 4 is integrally provided with a limiting bump 6 on the inner wall of the groove 5, and the lower end of the grenade body 1 is provided with a limiting groove 7 for inserting the limiting bump 6, so that when the rotating pallet 4 rotates It can drive the grenade body 1 to rotate together, and the lower end of the rotating platform 4 is provided with rotating blades 8 integrally in the circumferential direction. When a fire occurs, the fl...

Abstract

The invention relates to a fire extinguishing grenade. The fire extinguishing grenade comprises a grenade body, wherein the lower end of the grenade body is in an arc shape, a vertical block for keeping the grenade body in a vertical state is arranged at the bottom of the grenade body, a dry powder cavity for accommodating a dry powder extinguishing agent and an inflation cavity filled with compressed carbon dioxide are formed in the middle of the grenade body, a plurality of rotary spraying holes communicating with the dry powder cavity and the inflation cavity are formed in the side end of the grenade body, the rotary spraying holes rotate outwards towards one side with the center of the grenade body as the axis, and thermal expansion seal heads are embedded in the ends, away from the dry powder cavity and the inflation cavity, of the rotary spraying holes of the grenade body. The fire extinguishing grenade has the characteristics of timely fire rescue and the like.

Description

technical field [0001] The present application relates to the technical field of fire extinguishing equipment, in particular to a fire extinguishing grenade. Background technique [0002] At present, most of the existing fire extinguishers are composed of high-pressure fire extinguisher tanks and rubber or plastic hoses. When extinguishing a fire, it is necessary to manually pull or carry the fire extinguishing gas tank, and hold the hose to spray the fire source at a short distance. The operation is inconvenient and dangerous. , due to the short distance, firefighters will be subject to the danger of sudden explosion and high-temperature air burning, and it is difficult to rush into the effective distance for fire extinguishing when the fire flame is relatively large. The principle of the existing fire extinguishing grenade is the same as that of the military grenade. It needs to be opened for 5-10 seconds before the fire extinguishing agent is detonated and sprayed to exti...
