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 ...
