Abstract
The invention discloses a plastic wrap-around fin stabilization device for a fire extinguishing cluster bomb, belongs to the field of civil fire extinguishing bombs, and aims to solve the problem that the conventional unfolded fin stabilization device for a fire extinguishing bomb is inapplicable to tube launching. According to the stabilization device, an exhaust pipe body is made of a plastic material; a front exhaust pipe section metal shell and a rear exhaust pipe section metal shell are pressed at the front and rear ends of the exhaust pipe body respectively; a blind hole is machined at the rear end of a front exhaust pipe section; a fin support lug mounting groove and a fin shaft passing hole are machined on a support table of the rear exhaust pipe section metal shell; a support lug at the lower end of a fin is arranged in the fin support lug mounting groove of a rear exhaust pipe section; a fin shaft penetrates through the fin shaft passing hole of the rear exhaust pipe section metal shell and two support lugs of the fin; the rear end of the fin shaft passing hole is sleeved with a locking ring through a thread, so that the fin shaft is clamped downwards; and a spring is arranged on the fin shaft. The stabilization device is applicable to the tube launching, a rocket projectile runs in a rotating way to improve shooting accuracy, and fire extinguishing accuracy is high.
Description
Technical field
A kind of roll of plastic arc fin stabilization device for fire extinguishing shrapnel of the present invention belongs to civilian fire extinguisher bomb field.
Background technology
Forest is a main attemperator of whole ball ecological environment, and afforestation rate is to weigh an important indicator of a country quality.China is with a vast territory, and weather is complicated, and the hills, mountain area is many, and area of woods is large.Be subjected to forest fire that short of rain, arid, thunder and lightning, earthquake, human factor etc. cause at China's different regions frequent occurrence, the forest extinguishing situation is sternly pretty.
The place that forest fire occurs all is high mountain or hills generally, and the hill path is rugged and rough, affected by this, and fire extinguishing personnel, vehicle etc. can not in time arrive, so fire extinguisher bomb needs long-range emission.The similar fire-fighting rocket bomb of China all adopts not folding fin stabilising arrangement of plastic monoblock at present, inapplicable tubular type emission, and rocket ejects gun muzzle flight and does not rotate, a little less than the antijamming capability, when improving range, fire accuracy is relatively poor, can close up volume arc fin stabilization device and can effectively solve the long range accuracy problem.But the closed up volume arc fin stabilization device in traditional rocket projectile, its empennage cylinder and empennage adopt the metal material machine to add and form, and material own has determined that the quality of stabilising arrangement is heavier, deposit the speed height behind the arrival ground, easily produce spark, can cause burning to the dry sod in ground in the forest; And the empennage cylinder that is connected with empennage is and the spout body parts processing, and with the metalwork screw thread socket of the one at spout body two ends compacting, machine adds, welding procedure complicated, if therefore adopt plastic material to process this stabilising arrangement, needs the structure of redesign journal stirrup junction.
Summary of the invention
The objective of the invention is in order to solve the not folding fin stabilising arrangement of traditional fire-fighting rocket bomb one processing, inapplicable tubular type emission, when Far Range, fire accuracy is relatively poor, use for reference traditional metal and can close up the structure of volume arc fin stabilization device, a kind of roll of plastic arc fin stabilization device for fire extinguishing shrapnel is provided.The objective of the invention is to be achieved through the following technical solutions:
A kind of roll of plastic arc fin stabilization device for fire extinguishing shrapnel of the present invention comprises jet pipe leading portion metal shell, spout body, jet pipe back segment metal shell, sail shaft, spring, fin blade, retaining ring, retainer plate, brace table;
Spout body adopts plastic material, jet pipe leading portion metal shell and the jet pipe back segment metal shell that is used for connection suppressed in the front-end and back-end of spout body respectively one, the rear end of jet pipe leading portion is processed with blind hole, the front end of jet pipe back segment metal shell to around extend brace table, the empennage journal stirrup mounting groove and the caudal wing shaft that are processed with at same axis on the brace table of jet pipe back segment metal shell pass through the hole; The journal stirrup of empennage lower end is installed in the empennage journal stirrup mounting groove of jet pipe back segment, caudal wing shaft inserts from the stabilising arrangement lower end, and pass successively the caudal wing shaft of jet pipe back segment metal shell by two journal stirrups of hole and empennage, front end withstands in the blind hole of jet pipe leading portion rear end, caudal wing shaft at the jet pipe back segment is socketed retaining ring by rear end, hole screw thread, make the downward screens of caudal wing shaft, and by alignment pin retaining ring and jet pipe back segment are fixed; On the caudal wing shaft between two journal stirrups of empennage spring is installed, realize opening and closing up of the relative spout body of fin blade, and spacing to the empennage opening angle of the empennage journal stirrup mounting groove by jet pipe back segment metal shell, the fin blade after closing up is located by retainer plate; Fin blade adopts volume arc fin.
Beneficial effect:
Compact conformation of the present invention, processing technology be simple, be easy to assembling, and major part is the nonmetallic materials die forming, can not make the dry sod generation in ground second-time burning in the forest, and lightweight, reduces product and bears a heavy burden; Fin blade can close up, and suitable tubular type emission makes the rocket projectile spiraling to improve fire accuracy, and the fire extinguishing degree of accuracy is high.
