Multistage weight reduction releasing device applied to intelligent forest fire extinguishment aerial bombs

Abstract

The invention provides a multistage weight reduction releasing device applied to intelligent forest fire extinguishment aerial bombs. The multistage weight reduction releasing device comprises an aerial bomb frame, aerial bomb assemblies and control units, wherein the aerial bomb assemblies and the control units are placed in the aerial bomb frame; mounting plates are arranged at the upper ends of the aerial bomb frame; the control units comprise electromagnet assemblies and lever weight reduction mechanisms; the electromagnet assemblies comprise connecting blocks mounted on the mounting plates, direct current electromagnets mounted on the connecting blocks, and expansion rods fixedly connected with inner cores of the direct current electromagnets; the lever weight reduction mechanisms comprise first brackets, second brackets and third brackets that are mounted on the mounting plates; first cross beams are mounted on the first brackets in a hinged manner; second cross beams are mounted on the second brackets in a hinged manner; third cross beams are mounted on the third brackets in a hinged manner; the first cross beams are vertically lapped on the second cross beams; the second cross beams are vertically lapped on the third cross beams; the third cross beams are vertically lapped on the expansion rods; and the aerial bomb assemblies are hung on the first cross beams through lifting ropes. The multistage weight reduction releasing device is simple in structure, and can realize the effects of quick, high-efficiency and safe releasing of the aerial bombs.

Description

technical field [0001] The invention relates to an aerial bomb delivery device, in particular to a multi-stage weight reduction delivery device applied to intelligent forest fire-fighting aerial bombs, which belongs to the field of fire protection. Background technique [0002] Forest fire is a serious worldwide natural disaster, which has caused immeasurable losses to human resources and the environment. At the scene of a forest fire, the first fires are often dwarf bushes and ground vegetation, which are called ground fires. When the ground fire is accompanied by strong winds, or encounters vines and low-hanging branches on the trunk, the fire will rise to the crown of the tree and become a crown fire. The fire takes advantage of the wind, and the wind helps the fire to spread and spread extremely quickly. The forest fires in China's Greater Khingan Mountains in 1987, California in the United States, and Australia in 2008 were all dominated by tree crown fires. With the ...

Problems solved by technology

However, when the spring is tightened, it needs to be tightened artificially. Because the required spring force is relatively large, it is laborious to tighten it manually; at the same time, the spring needs to overcome multiple frictional forces generated by the gravity of the aerial bomb, but in fact, only one supporting aerial bomb needs to be removed. The fulcrum of the aerial bomb will bounce off; both the spring and the electromagnet can achieve the effect of short-term reset. This device is used for both. The launch of the bomb, but there are some problems
