Fig. 4 is the basic structure that in delivery device gondola 1, single file is single-row, and whole delivery device gondola 1 can be regarded as its fabricate block.As shown in the figure, upper beam 5, curb girder 6, crossbeam 9, underbeam 11 are welded as a whole, the general frame of composition delivery device gondola 1.Its center member 9 is provided with through hole 17.Underbeam 11 tail end is provided with through hole 18, and medium position is provided with tapped bore 19.
As shown in Fig. 4,7,8, top panel 7 is welded in above the plane framework of upper beam 5 and crossbeam 9 formation.Dividing plate 12 is connected between upper beam 5 and underbeam 11.Dividing plate 14 is connected between lower and upper cross-member 9.Dividing plate 12 and dividing plate 14 1 work and make fire extinguishing bomb 2 laterally fixing.
As shown in Figure 5, its upper end is provided with a through hole 20 to side panel 8, and on the through hole 17 making it be connected to crossbeam 9 by bearing pin, composition revolute pair, makes side panel 8 can rotate around upper beam 9.Its lower end is provided with two holes 21 as shown in the figure, and two tapped bore 22.
As shown in Figure 6, one end is provided with a through hole 23 to lower faceplate 10, and on the through hole 18 making it be connected to underbeam 11 by bearing pin, composition revolute pair, makes lower faceplate 10 can rotate around underbeam 11.The other end is provided with two projecting shafts 25.Circular groove 26 is provided with outside projecting shaft 25.Projecting shaft 25 is provided with circular hole 27.Respectively there is a tapped bore 24 both sides, plate 10 middle part below.
As shown in Figure 10, extension spring 28 one end annulus is fixed by screws on the tapped bore 24 of lower faceplate 10 middle part, and the other end is fixed by screws on the tapped bore 19 of underbeam 11.Extension spring 28 does not affect the rotation of lower faceplate 10 around underbeam 11, and its effect ensures that the pose of lower faceplate 10 can not perpendicular to underbeam 11.
As shown in Fig. 1,2,4, multiple bearing 15 is welded in underbeam 11 lower surface, for supporting whole gondola 1, makes underbeam and maintenance space, ground.Supporting nahlock 13 is freely placed in below lower faceplate 10, for making the upper plane maintenance level of lower faceplate 10.
Bomb pad 3 is for separating and supporting fire extinguishing bomb 2.As shown in Figure 7, be installed between fire extinguishing bomb 2.
As shown in Figure 3, multiple suspension ring 4 are connected with upper beam 5, by suspension ring 4 and hoist cable 29, delivery device are hung and are loaded on helicopter 30.
Control mechanism 16 is for controlling the input of fire extinguishing bomb 2.As shown in Figure 8,9, primarily of tractive magnet supporting seat 31, tractive magnet 33, draw the compositions such as bait 32, pull bar 34, cylinder bayonet lock 35, draw-bar seat 36.
As shown in Figure 9, tractive magnet supporting seat 31 is welded on side panel 8 middle lower portion.Tractive magnet 33 is fixed on tractive magnet supporting seat 31.Bait 32 is drawn to be connected with the iron core external part of tractive magnet 33 by straight pin.Draw-bar seat 36 is bolted in the tapped bore 22 being fixed on side panel 8 bottom.Pull bar 34 one end annulus is enclosed within draw-bar seat 36, and one end is by bearing pin and draw bait 32 to link together, and pull bar 34 can rotate around draw-bar seat 36.The cylinder bayonet lock 35 by pinned connection pull bar 34 is equipped with.
As shown in Figure 8, Compress Spring 37 is arranged in the circular groove 26 outside projecting shaft 25, and Compress Spring 37 one end is fixed on bottom circular groove 26, other end retractable.
One, the installation of fire extinguishing bomb
As shown in Fig. 2,7,8: be placed in ground by stable for bomb delivery device.Side panel 8 is rotated up, gondola mouth is opened.Support nahlock 13 is freely placed in below lower faceplate 10, makes the upper plane of lower faceplate 10 be in horizontality, ready with fire extinguishing bomb 2 for installing bomb pad 3.As shown in Figure 7, successively bomb pad 3 and fire extinguishing bomb 2 are installed, to filling.
Tractive magnet 33 is energized, and the effect that inner-core is subject to magnetic force is internally moved, and drives and draws bait 32 to move.This action makes cylinder bayonet lock 35 upward movement by the leverage of pull bar 34.Be rotated down by side panel 8 and extrude Compress Spring 37, make hole on side panel 8 21 through the projecting shaft 25 on lower faceplate 10, side panel 8 is in vertical state.Now tractive magnet 33 power-off, the inner-core of tractive magnet 33 gets back to original position under the effect of natural resiliency potential energy, and due to inter-agency impact, cylinder bayonet lock 35 moves downward, and penetrates the circular hole 27 on projecting shaft 25.Cylinder bayonet lock 35 blocks side panel 8 makes it fix, and completes the action of closed gondola.
Repeat above action, according to reality fire extinguishing task needs, successively fire extinguishing bomb 2 is installed.
Two, hanging of delivery device is carried and the input of fire extinguishing bomb
The means of delivery of bomb delivery device is straight eight type helicopters or similar parameters helicopter.Helicopter is equipped with winch, the hoist cable that helicopter 30 hangs down is hooked on the suspension ring 4 of delivery device.When there is forest fire, the bomb delivery device handling of having loaded to overhead, the forest scene of a fire, is carried out the order input of fire extinguishing bomb, thus is completed fire extinguishing task by helicopter 30 according to the release sequence set by control mechanism 16.
Concrete launch process is as follows: as shown in Figure 8,9, 10, and upper computer sends instruction to the corresponding control mechanism 16 of the fire extinguishing bomb 2 that need throw in.Tractive magnet 33 in control mechanism 16 is energized work, and the effect that inner-core is subject to magnetic force is internally moved, and drives and draws bait 32 to move.This action makes cylinder bayonet lock 35 upward movement by the leverage of pull bar 34, and cylinder bayonet lock 35 departs from the circular hole 27 on projecting shaft 25.Under the elastic force effect that Compress Spring 37 has stored, side panel 8 rotates and departs from the projecting shaft 25 of lower faceplate 10.Lower faceplate 10 is rotated down under fire extinguishing bomb 2 and bomb pad 3 Action of Gravity Field, and fire extinguishing bomb 2 and bomb pad 3 have fallen input action.
Bomb supply volume is controlled according to task site environment by control mechanism 16.After completing fire extinguishing task, helicopter carry bomb delivery device gets back to loading base, reload fire extinguishing bomb 2 or unloading.
Three, fire extinguishing bomb unloading and reload
When helicopter hang carry a bomb delivery device get back to loading base time, if forest fire is put out not yet, then continue load fire extinguishing bomb 2 in case next time throw in fire extinguishing.If forest-fire model is complete, and in bomb delivery device, still have the fire extinguishing bomb 2 do not thrown in, then need to unload.
When need continue to load, due to the effect of extension spring 28, lower faceplate 10 under gravity can not perpendicular to underbeam 11.Drop in surface process at input gondola 1, lower faceplate 10 comes back to original position.Repeat above-mentioned fire extinguishing bomb installation process to reload fire extinguishing bomb 2.
When need unload, tractive magnet 33 is energized work, and the effect that inner-core is subject to magnetic force is internally moved, and drives and draws bait 32 to move.This action makes cylinder bayonet lock 35 upward movement by the leverage of pull bar 34, and cylinder bayonet lock 35 departs from the circular hole 27 on projecting shaft 25.Under the elastic force effect that Compress Spring 37 has stored, side panel 8 rotates and departs from lower faceplate 10.Side panel 8 is rotated up, opens gondola mouth, unload fire extinguishing bomb 2 and bomb pad 3 successively from top to bottom.Complete unloaded operation.
The full bullet-loading capacity weight of this device is slightly less than 3000kg, single fire extinguisher bomb weight 20kg, total bullet-loading capacity 96, actual load ABC ultra-fine dry powder extinguishing agent 1296kg.Be suitable for straight eight type helicopters or similar parameters helicopter, as rice 171 uses.Every sortie full-load run, can control particularly serious forest fire 70-140 rice live wire completely.
