Embodiment Construction

[0029] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0030] like figure 1 , the helicopter special-purpose pod type forest fire extinguishing aerial bomb throwing device of the present invention is made up of two major parts, is ground support part and aerial suspension part 1. The ground support part is composed of the ground support module II placed on the ground in a certain way. Figure 1-Figure 3 Three views of the general assembly drawing of a special pod-type forest fire-fighting delivery device for a helicopter that can carry 16 forest fire-fighting aerial bombs.

[0031] Figure 4-Figure 7 It is a three-view and partial view of the general assembly drawing of the aerial suspension part of the 16 aerial bomb delivery devices. It can be seen from the figure that the aerial suspension part I of the 16-piece aerial bomb delivery device is a rigid machine composed of four smallest assembly units that are cons...

Abstract

The invention provides a special nacelle type forest fire extinguishing bomb throwing device for a helicopter. The device consists of a ground bracket and an aerial hanging part; the ground bracket is a detachable member assembly, and mainly comprises a supporting flat plate, a supporting seat and bracket legs; and the aerial hanging part is formed by assembling smallest assembly units through a hanger beam and a fixed hanging hoisting ring, wherein the hanger beam is a hanging bearing beam, the fixed hanging hoisting ring is a member formed by fixedly connecting a fixed buckling plate and a nut hoisting ring together, and the smallest assembly units and an upper hitch beam are fixedly connected together by the fixed hanging hoisting ring through U-shaped bolts. The device is mainly applied in the occasions of hanging and transporting a forest fire extinguishing bomb and throwing the forest fire extinguishing bomb over the fire scene when the helicopter is used for forest fire extinguishment. The device has modularized structural function and simple structure, and is convenient to assemble and maintain.

Description

technical field [0001] The invention relates to a fire fighting device. Specifically, it is a device for hanging, transporting and dropping bombs by helicopters for forest fire extinguishing aerial bombs. Background technique [0002] Forest fire is a serious worldwide natural disaster, which has caused immeasurable losses to human resources and the environment. Therefore, forest fire suppression is an important task for human beings all over the world. [0003] With the advancement of human science and technology, helicopters, an advanced means of transportation with relatively large carrying capacity, are playing a unique role in the field of forest fire prevention and fire extinguishing. At present, at home and abroad, carry fire extinguishing agent or water to spray from high altitude mainly by helicopter for putting out forest canopy fire. Due to the strong updraft and turbulence over the fire scene, the fire extinguishing agent is dispersed by the strong high-tempera...
