Abstract
The utility model discloses a smoke and fire lighter for artificial precipitation, which is formed by the closing of an inner casing and an outer casing, wherein, a cavity is arranged between the inner casing and the outer casing; smoke and fire catalyst is filled in the cavity; the bottom end of the inner casing is provided with a connection opening of a cannon opening. The utility model is matched with a bullet of artificial rain. The utility model plays excess catalytic action on 'rain cloud' or 'hail cloud'. The utility model can improve the nucleation rate and reduce the transmission cost. The utility model is especially suitable for direct carrying the smoke and fire lighter on a high cannon with 37 mm.
Description
The utility model relates to a kind of pyrotechnics generating means, specifically is exactly a kind of pyrotechnic generator that is used for artificial rainfall.
The rainfall preventing hail technology of present stage weather modification generally adopts 37mm antiaircraft gun emission artificial rainfall rail-proof bomb, the pyrotechnics catalyzer (containing silver iodide) that is equipped with in this bullet thus with the blast spreading produce a large amount of nucleus in the clouds, " nimbus " or " hail cloud " transformed, reach the purpose of rainfall preventing hail: but this kind method is because each bullet only carries 1 gram silver iodide, and the unit nucleation rate is low, is 10 in the time of-10 ℃
13Individual nucleus/every gram silver iodide.With the appearance of new pyrotechnic material, the methods of rainfall hail mitigation are also improved very fast in recent years.Increase journey as the disclosed 37mm of CN2167516Y utility model and dispense the artificial rainfall rail-proof bomb, this plays entrained pyrotechnics catalyzer in 4000-7000m range running, at the bottom of bullet, spray catalysis smog, dispense and urge rain hail suppression nucleus, dispense while flying, when the projectile flight delay initiation device of fuse bullet that detonates during to the 7000m left and right sides, quick-fried big waves dispenses the silver iodide in the bullet in the clouds again.Dispensing this pyrotechnic material nucleation rate and improve greatly, is 10 in the time of can reaching-10 ℃
15Individual nucleus/every gram silver iodide.But this kind method is because the change of projectile structure needs special supporting emitter, and common 37mm antiaircraft gun can not satisfy its needs, and the expense of unit nucleation is higher.Also have and adopt aircraft to become fire balloon to carry that the pyrotechnic material lift-off dispenses, but, influenced practicality because its task difficulty is big.
The purpose of this utility model is to provide a kind of nucleation rate height, and simple in structure, launch cost is low, and is easy to operate, directly carries the pyrotechnic generator of emission on the 37mm antiaircraft gun.
The purpose of this utility model is realized by following technical scheme: it is formed by inner casing and enclosure closed, form cavity between the two-layer housing, cavity contains the pyrotechnics catalyzer, be provided with gun muzzle seam in the inner casing bottom, for pyrotechnic generator can be gone up to the air reliably, its inner casing is up big and down small conically shaped; Shell is up-small and down-big arc-shaped surface housing.For the ease of lighting the pyrotechnics catalyzer, on inner casing and shell, have through hole, on inner casing and the formed cavity inner wall of shell, post silk.In order to make the inner casing bore keep stable, and make inside and outside two-layer shell, be provided with the banding ring at the interface upper limb in node place adequate closure down.For the utility model is connected reliably with gun muzzle, described gun muzzle seam external diameter is that 37mm is advisable.
Owing to adopted above structure, this pyrotechnic generator can directly carry lift-off by bullet on the 37mm antiaircraft gun, aloft running orbit is stable, and is little to the flying height influence of bullet, entrained pyrotechnics catalyzer is ignited with the bullet blast, and its nucleation rate of being fuming can reach 10
15Individual nucleus/every gram silver iodide.
Below in conjunction with drawings and Examples the pyrotechnic generator that the utility model proposes is described further.
Fig. 1 is the profile of this pyrotechnic generator.
With reference to Fig. 1, the utility model is formed by inner casing 2 and shell 1 closure, forms cavity between the two-layer housing, and cavity contains pyrotechnics catalyzer 6, and inner casing 2 bottoms are provided with gun muzzle seam 4, and its external diameter is chosen as 37mm.Inner casing 2 is made up big and down small conically shaped, and shell 1 is up-small and down-big smooth arc-shaped surface housing.For the ease of the pyrotechnics catalyzer 6 that ignites, 4 through holes 7 that diameter is 4mm that on inner casing 2, distribute, 6 through holes 5 that diameter is 2mm distribute on shell 1.Meanwhile, on inner casing 2 and shell 1 formed interlayer cavity inner wall, post silk 8, can prevent that pyrotechnics catalyzer 6 from overflowing from through hole 5 before burning.
During the artificial rainfall operation, interface 4 of the present utility model is inserted on 37mm antiaircraft gun gun muzzle, when the artificial rain bomb's ball that is launched is got from gun barrel, the bottom of inner casing 2 just in time is stuck in bullet bearing band place when passing pyrotechnic generator, banding ring 3 makes inner casing 2 bores keep stable, and generator is carried lift-off by bullet, bullet blast when flying to certain altitude, flame is by through hole 5, burning silk 8, and then lights pyrotechnics catalyzer 6 rapidly and make it abundant burning.The CN88104287 patented product that the pyrotechnics catalyzer that adopts provides for Beijing Institute of Technology reaches 10 during burning fuming nucleation rate-10 ℃ aloft
15Individual nucleus/every gram silver iodide.The vertical diameter of present embodiment pyrotechnic generator is about 37mm, generally carries the 15-40 gram at every and is advisable.
