Abstract

The present invention connects several rockets of rope by the strand explosive, automatically start the strand explosive by the crown fire that comes, the strand explosive produces the linear explosive effect, several rockets are launched simultaneously, it is fried simultaneously diffusing that several inhibition bullets are served aerial certain altitude, and crown fire just can be knocked out by the moment of inhibition bullet colony blast like this.

Description

Strand rocket for extinguishing crown fire in chemical apparatus and method

The present invention relates to put out forest fire, especially the method and apparatus of crown fire.

The forest fire can be divided into three types substantially, and the one, surface-fire, the 2nd, underground fire, the 3rd, crown fire, these three types of crown fires are the most violent, and fltting speed is fast, and is 25KM/ hour, than preceding two kinds of degree of danger height, destructive big.The coniferous forest that crown fire, broad-leaf forest on average also give birth to ability and account for 20%, and wherein, needle is also given birth to ability will be less than 10%.As seen the extent of injury of this fire.

Crown fire, it is a kind of forest fires form of burning along tree crown, leaf branch and trunk are burnt in top, treelet and wooden is down burnt in the bottom, the leafy close growth of reporting to the leadship after accomplishing a task of the top branch of setting in the intensive woods, and the carrying capacity of comburant is big, so the continuity of crown fire is very strong, crown fire is once generation sees that far the fire wave that soars advances fast, and is irresistible.

This fire is mainly in prolonged drought coniferous forest, middle-aged forest, uneven aged forest, broad-leaf forest and southern eucalyptus woods etc.

Relatively advanced in the world country adopts aircraft to spread water to crown fire more and spreads chemical agent, or the method for isolating that chops at a tree in the place ahead of fire is puted out a fire to save life and property.The former national power is strong, and aircraft is many, and accuracy rate is low but this mode is put out a fire, and waste is big.The latter, the mechanization degree height, it is slow to form the fire insulation ability, and certain destruction is arranged.

China's present stage is because the constraint of financial resources, to this fire can only be to put out a fire to save life and property after waiting to drop to surface-fire, also do not possess the ability of pouncing on crown fire in other words, although this several method is arranged in the world, but in fact effect is very low, also be the way of having no way, current flourishing U.S.'s forest fires burn ten days 20 days it is arranged, so crown fire should be a great problem in world's forest fire protection work.

The objective of the invention is to propose a kind of new method and new tool of anti-, extinguishing crown fire according to the combustion law of crown fire.

Crown fire is the inflammable leaf of the intensive forest upper end because the high strength surface-fire has ignited, and branch is under the wind-force effect and form.Its basic burning form is such: because mostly intensive forest inflammable carrying capacity is on top, so crown fire is 5～25 meters aerial burning on the distance face of land, under wind action, form aerial fire wave or fiery (inflammable gas and dust converge, temperature is after burning point, the explosive combustion that produces is fiery), its combustion intensity is big, speed is fast.Therefore extinguishing crown fire should aloft carry out.In view of the above, the present invention proposes a kind of simple to operate, and fire combustion then can start rapidly automatically, and the degree of accuracy is high and can be at 5～25 meters aerial while large tracts of land method for extinguishing fire and device.Concrete grammar is, make the inhibition bullet and it is installed on the rocket launching seat according to this mature technology of inhibition, with the strand explosive several rocket batterys are locked together then, and on the strand explosive, be provided with if with doing a detonator, make the extinguishing crown fire device like this, during use it is placed on the face of tree vacant lot, extract several streak explosives out, tie up detonating primer, it is hung 10 meters left and right sides eminences in the tree.When crown fire burns, extension detonator in the tree ignites, blasting cap detonation makes the strand explosive produce linear explosive, several rockets that are through on the strand explosive are launched simultaneously, the cap of igniting in the inhibition bullet ignites again during rocket launching, through fuse detonation inhibition bullet, make fried loosing of same time of several inhibition bullets aloft, crown fire is under the impulse of large tracts of land chemical and suffocate, the casual fire retardant chemistry medicament of comburant surface cloth, comburant can not be burnt away, reached the fire extinguishing purpose.

Below in conjunction with accompanying drawing strand rocket for extinguishing crown fire in chemical device of the present invention is given to specify.

Fig. 1 is an extinguishing device structure chart of the present invention.

Fig. 2 is emission seat shell structure figure.

As shown in Figure 1, the inventive system comprises a hard plastic cover 1, chemical 2 is equipped with in its inside, be inserted with a charge tube 3 in the middle of the extinguishing chemical, there is a detonator 4 lower end of charge tube 3, detonator 4 joins with fuse primer 5, fuse primer 5 is connected on the cap 6 of igniting, be placed in the rocket launching seat housing made from alloy aluminum 10 with top, emission seat housing 10 is provided with explosive contact groove 12, place the dividing plate made from alloy aluminum 11 in it, adjoining the contact groove has a groove 13 to be used to place rocket launching explosive 9, housing 10 bottoms are provided with strand explosive line perforation 14 and are used to hold shelly explosive line 7, and its underpart also has a sulculus 15 to be used to place bayonet lock 8 so that antilift wire shaped explosive charge line.

Claims

1, a kind of method of strand rocket for extinguishing crown fire in chemical, it is characterized in that many rockets that have the inhibition bullet are connected in series with the strand explosive, be placed on tree vacant lot face, extract some streak explosives out and tie up detonating primer, hang 10 meters eminences in the tree, when crown fire burns, extension detonator in the tree ignites, blasting cap detonation causes strand explosive linear explosive, thereby several rockets are launched simultaneously, the inhibition bullet that ignites again during rocket launching makes its fried simultaneously loosing aloft, and crown fire is suffocated under the large tracts of land chemical impacts.

2, the strand rocket for extinguishing crown fire in chemical device that a kind of method is according to claim 1 used, it is characterized in that: comprise that an inside is equipped with the housing of chemical, be inserted with a charge tube in the middle of the extinguishing chemical, there is a detonator its lower end, detonator and fuse primer join, fuse primer is connected on the cap of igniting, they are installed in the rocket launching seat housing together, emission seat housing has an explosive of placing dividing plate to contact groove, adjoining the contact groove has a groove to be used to place the rocket explosive, an emission seat housing bottom has strand explosive line perforation, and there is a sulculus that is used to place bayonet lock its underpart.
