Abstract

The invention provides a forest fire fighting aerial bomb throwing device based on a ball rod combination mechanism. The forest fire fighting aerial bomb throwing device comprises a plurality of throwing units, throwing barrels of the throwing units are fixedly arranged on a frame, conical holes are formed in the throwing barrels, driving rings are arranged on the throwing barrels in a sleeving mode, and limiting rings are arranged on the throwing barrels in a sleeving mode; the ball rod combination mechanism comprises a steel ball, a forest fire fighting bomb, a limiting ring, a first connecting rod, a second connecting rod and a third connecting rod, the steel ball is movably located in the conical hole, the forest fire fighting bomb is arranged in the throwing barrel in an up-down moving mode, a bomb head part makes contact with the steel ball, and the steel ball is in tangent fit with the inner wall of the limiting ring; one end of the first connecting rod is hinged to the driving ring; two ends of the second connecting rod are respectively hinged with the first connecting rod and the limiting ring; two ends of the third connecting rod are respectively hinged with the first connecting rod and the frame; the electromagnet is in transmission connection with the driving ring. The device has the advantages of being simple in structure, convenient to operate, small in throwing action driving force, fast in throwing action response, high in throwing stability and reliability, capable of automatically resetting after throwing and the like.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a forest fire extinguishing aerial bomb delivery device based on a club combination mechanism. Background technique [0002] Forest fires are mainly divided into underground fires, surface fires and crown fires, among which forest crown fires are the most harmful, and the suppression of major forest fires dominated by crown fires is an international problem. At present, many countries have begun to widely use special aircraft for forest fire fighting to spray water or fire extinguishing agent over the fire scene to extinguish the fire. Dispersion, low fire extinguishing efficiency, poor suppression effect. [0003] The use of forest fire extinguishing aerial bombs to extinguish forest crown fires is a brand-new forest fire extinguishing method. After the forest fire extinguishing aerial bombs are released, they move to the canopy area and detonate, so that the ultra-fine dry powder...
