It is said that the colloidal foam fire extinguishing agent should be preferred, but the existing colloidal foam fire extinguishing agent, a class is that one or more water-insoluble substances are originally contained in the raw material, and long-term storage is easy to delaminate and fail; The water-insoluble matter needs to be prepared and used immediately; there is another kind that separates the sediment and the precipitated raw materials in the fire extinguishing bomb, but after the fire extinguishing bomb is detonated, it is difficult to ensure that the sediment and the precipitated raw materials are mixed and sprayed evenly, and it is difficult to generate Sufficient colloidal substances and the gas required to generate foam, that is, its ability to extinguish fires is also greatly reduced

Abstract
The invention discloses a ground rotation type carbon dioxide colloid gas aphrons extinguishing bomb. The ground rotation type carbon dioxide colloid gas aphrons extinguishing bomb comprises a bomb body internally provided with a foam extinguishing agent and a control device used for controlling the bomb body to spray out the foam extinguishing agent; a cavity containing the foam extinguishing agent is arranged in the bomb body, a feeding valve is arranged at the tail of the bomb body, a plurality of tail wings are arranged on the side wall of the tail of the bomb body, and the control device comprises a positioning ring divided into two portions, a pressing sleeve, a stand column, a bottom disc and a supporting rod, nozzles are evenly formed in the position, close to the head end and located in the middle of the thickening portion, of the bomb body, and the nozzles are sealed through a seal plug; the upper portion of the thickening portion of the bomb body is sleeved with the positioning ring, and the positioning ring is located in the pressing sleeve and is connected with the pressing sleeve through a bolt, and the pressing sleeve is arranged on the bomb body in a sleeving manner and is pressed on the outer portion of the seal plug, the bottom end of the pressing sleeve is connected with the top end of the bottom disc through the stand column, and the center of the bottom of the bottom disc is fixedly connected with the supporting rod. The extinguishing bomb can be stored for a long time, the extinguishing agent can be evenly sprayed, the compact, durable and fireproof isolation effect can be generated, and rapid extinguishing is obtained.
Description
technical field [0001] The invention belongs to the technical field of forest fire protection, and in particular relates to a ground-rotating carbon dioxide colloidal foam fire extinguishing bomb. Background technique [0002] In recent years, with global warming, forest fires have occurred frequently. Especially in the remote virgin forest, once an accidental fire occurs, it is difficult to extinguish it. Most of the water sprayed by helicopters flows away along the hillside, and the wet trees will be quickly dried and ignited again. Throwing fire extinguishing bombs should be a good method, but the existing fire extinguishing bombs only have dry powder fire extinguishing bombs and foam fire extinguishing bombs. Dry powder fire extinguishing bombs have limited adhesion to combustibles, and are easy to drift away with the airflow, losing their fire extinguishing function; foam fire extinguishing bombs have good adhesion, but in the open field, the foam itself is difficult ...
