Detailed description of the invention
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1 ~ 9, the present invention mainly comprises delivery device general frame 1, controlling organization 3 and bomb assembly 34 etc.
Delivery device general frame 1 is for fixedly mounting controlling organization 3 and bomb assembly 34, and as Fig. 1, shown in 2, general frame 1 is primarily of compositions such as horizontal welding plate 4, longitudinal welding plate 5, arc weld tabs 6 and suspension ring 8.Horizontal welding plate 4, longitudinal welding plate 5 and arc weld tabs 6 are fixed together, and composition round rectangle space as shown in Figure 2, as the protection guide cylinder 7 of fire extinguishing bomb 2, for installing bomb assembly 34.Longitudinal welding plate 5 and multiple suspension ring 8 on upper strata are connected, and by suspension ring 8 and hoist cable 9, delivery device are hung and are loaded on helicopter 10, see Fig. 3.
Controlling organization 3 is for controlling the input of bomb assembly 34.As shown in Figure 4, form primarily of left tray 12 and right bracket 13 two parts.Left tray 12 and right bracket 13 are inserted in the slot 11 of horizontal welding plate 4 in general frame 1 by the plate 32 of both sides, and fix with bolt.
As shown in Figure 5, left tray 12 is welded with extension sleeve supporting seat 23, tractive magnet supporting seat 18 and left bearing base 27.Extension sleeve 14 and tractive magnet 19 are fixedly mounted on left tray 12 by extension sleeve supporting seat 23 and tractive magnet supporting seat 18 respectively.Compress Spring 15 is inserted in the diameter segment of telescopic shaft 16, is encapsulated in extension sleeve 14 after assembling.Telescopic shaft 16 remains on the motion of horizontal direction by the telescopic shaft supporting seat 28 be welded on left bearing base 27.Hanging bar 29 and telescopic shaft 16 are linked together by bearing pin 20.The hanging bar roller 22 by pinned connection is had at the other end of hanging bar 29.Draw-bar seat 24 is welded on extension sleeve 14 left end, it has the pull bar 26 by pinned connection.Pull bar 26 there are the cylinder bayonet lock 25 by pinned connection and La Er 17.Ear 17 is drawn to be connected with the iron core external part of tractive magnet 19 by straight pin.
As shown in Figure 5, right bracket 13 is welded with right bearing base 31, right bearing base 31 is welded with the gathering sill 21 rolled for hanging bar roller 22
Bomb assembly 34 for the installation of fire extinguishing bomb 2 with fixing.As shown in Figure 6, bomb assembly 34 forms primarily of lifting dish 35, fire extinguishing bomb 2, traction liner 33.Lifting dish 35 is made up of the suspension rod of upper and lower two layers of support board and centre, and upper end has lifting rope 30 that bomb assembly 34 can be made to hang on the hanging bar 29 of controlling organization 3.
Traction liner 33 is for separating and installing fire extinguishing bomb 2, so that fire extinguishing bomb 2 is better arranged on bomb assembly 34.As shown in Figure 7, traction liner 33 is made up of the honeycomb paper gasket 36 of hollow out, and outside is surrounded by ventilative flexible fabric 37.Traction liner 33 is connected on the rear end cap 39 of fire extinguishing bomb 2 by umbrella rope 38.
One, the installation of fire extinguishing bomb
As shown in Figure 6, fire extinguishing bomb 2 is installed in traction liner 33.It can be used as an entirety to be one group with four, be loaded into respectively lifting dish 35 two-layer up and down in, composition bomb assembly 34.
Bomb assembly 34 as shown in Figure 4, is vertically sling by lifting appliance by bomb delivery device minimum unit, and handling is to the top of the bomb delivery device that need load.Control lifting appliance bomb assembly 34 to be loaded in protection guide cylinder 7.The left tray 12 of controlling organization 3 and right bracket 13 are arranged on the protection guide cylinder 7 at bomb assembly 34 place, make the lifting rope 30 above bomb assembly 34 through the hanging bar 29 of controlling organization.Now, bomb delivery device minimum unit installs.
In like manner, according to reality fire extinguishing task needs, bomb assembly 34 is loaded successively.
Two, hanging of delivery device is carried and the input of fire extinguishing bomb
The delivery vehicle of bomb delivery device is straight eight type helicopters or similar parameters helicopter.Helicopter is equipped with hoist engine, the hoist cable that helicopter 10 hangs down is hooked on the suspension ring 8 of fire extinguishing bomb 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 10 according to the release sequence set by controlling organization 3.
Concrete launch process is as follows: host computer sends instruction to the corresponding tractive magnet 19 of the fire extinguishing bomb that need throw in, makes its work that is energized.The effect that tractive magnet 19 inner-core is subject to magnetic force is internally moved, thus drive draws ear 17 to move.This action drives cylinder bayonet lock 25 to depart from original position by the leverage of pull bar 26.After cylinder bayonet lock 25 is pulled out original position, the elastic potential energy that Compress Spring 15 originally stored is discharged, and promotes telescopic shaft 16 and moves.Telescopic shaft 16 drives the hanging bar 29 connected by bearing pin 20 to move, and hangs motion in the gathering sill 21 of bar roller 22 on right bearing base 31 simultaneously.After one segment distance, hanging bar roller 22 departs from gathering sill 21, rotates under the Action of Gravity Field of self gravitation and bomb assembly 34 around bearing pin 20.The lifting rope 30 on bomb assembly 34 top, along the landing of hanging bar 29, completes the input of bomb assembly 34.
After bomb assembly 34 is controlled to throw in disengaging general frame 1 by controlling organization 3, due to the effect of empty air flow, fire extinguishing bomb 2 disperses mutually, and fire extinguishing bomb 2 is separated from each other with traction liner 33 simultaneously.As shown in Figure 8, utilize air drag, traction liner 33 is inflated above fire extinguishing bomb 2 and opens, now draw the effect that liner 33 serves extractor parachute, under the effect of tractive force, fire extinguishing bomb 2 rear end cap is separated with body, pulls out main aerial bomb parachute 40.Under the effect of main aerial bomb parachute 40, fire extinguishing bomb 2 drop to overhead, the forest scene of a fire and completes fire extinguishing task.
Fire extinguishing bomb 2 supply volume is controlled according to task site environment by controlling organization 3.After completing fire extinguishing task, helicopter carry bomb delivery device gets back to loading base, reload fire extinguishing bomb 2 or unloading.
Three, the unloading of fire extinguishing bomb
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.
Concrete uninstall process is as follows: removed with right bracket 13 two parts by left tray 12 corresponding for the bomb assembly 34 do not thrown in.By boom hoisting, bomb assembly 34 is hung from protection guide cylinder 7, and be steadily placed in ground fire-putting-out bomb placing position and complete unloading.
The present invention can serve straight eight type helicopters or similar parameters helicopter, and as rice 171, full bullet-loading capacity weight 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.Every sortie full-load run, can control particularly serious forest fire 70-140 rice live wire completely.
