Abstract
The utility model provides a centre cartridge igniter of a forest fire-extinguishing grenade and the forest fire-extinguishing grenade. The centre cartridge igniter comprises a circular-pipe-shaped main explosive pipe for being filled with flame eliminating explosive, wherein the main explosive pipe is provided with a ball body which is communicated with the main explosive pipe and has the diameter of 30-32cm; the ball body and the axis of the main explosive pipe are arranged on the same straight line; and the density of the flame eliminating explosive in the main explosive pipe is not less than 0.6g/cm<3>; The forest fire-extinguishing grenade comprises the centre cartridge igniter which adopts the technical scheme provided by the utility model. According to the utility model, the structure of the centre cartridge igniter of the forest fire-extinguishing grenade is improved, when the forest fire-extinguishing grenade explodes, the shock waves generated by the forest fire-extinguishing grenade are in the shape of an ellipsoid approximate to a round ball, so that fire extinguishing performance of the forest fire-extinguishing grenade can be achieved to the great extent regardless of the explosive stage of grenade body.
Description
Technical field
The utility model relates to the fire distinguisher technical field, is specifically related to a kind of fire-fighting bomb for forest center booster and fire-fighting bomb for forest.
Background technology
The center booster that existing fire extinguisher bomb uses is unified as diameter, fills the cylinder of flame arrest explosive, comprises main charge tube, band detonator part and the Delay Tube parts that connect successively along its length direction.Because to be diameter unified for the center booster, fills the cylinder of flame arrest explosive, the shock wave shape that its explosion time produces is fan-shaped perpendicular to booster.Therefore, only have when fire extinguisher bomb body state is perpendicular to ground according to the shock wave fire-fighting principle, the explosion wave competence exertion goes out maximum fire extinguishing effectiveness.Body plumbness always when fire extinguisher bomb arrives the fire point is so can not can both give play to maximum fire extinguishing effectiveness by every fire extinguisher bomb in actual forest extinguishing fight but in actual use.Thereby cause the wasting of resources, can't effectively put out a fire simultaneously, may cause the condition of a fire to incur loss through delay.
The utility model content
For the problems referred to above that prior art exists, the technical problems to be solved in the utility model is: the center booster of how fire extinguisher bomb being used improves, and also can bring into play to large extent its usefulness even the fire extinguisher bomb body is exploded under non-perpendicular state.
Solve this technical problem, the utility model adopts following technical scheme: a kind of fire-fighting bomb for forest center booster, comprise and fill the flame arrest explosive, the main charge tube of circular tube shaped, it is characterized in that: it is the spheroid of 30～32cm that described main charge tube is provided with the diameter that is communicated with it, the axle center of described spheroid and main charge tube is on same straight line, and the density of flame arrest explosive is not less than 0.6g/cm in the described main charge tube
3
Further, described spheroid is two, and along the axial alternate setting of main charge tube.
A kind of fire-fighting bomb for forest, described fire-fighting bomb for forest center booster adopts the structure of center booster in the technique scheme.
With respect to prior art, the utlity model has following advantage:
1, the utility model connection diameter on the main charge tube of fire-fighting bomb for forest center booster is the spheroid of 30～32cm, and
The axle center of spheroid and main charge tube is on same straight line, thereby when the fire-fighting bomb for forest explosion time, the shock wave shape of its generation will be the ellipsoid shape near ball, no matter this is so that at the state of explosion time how body, can both give play to the fire extinguishing effectiveness of fire extinguisher bomb largely.
2, the flame arrest explosive of general fire-fighting bomb for forest center booster is no more than at most 48g, the diameter of the spheroid that therefore connects on the main charge tube can not surpass 32cm, through inventor's test of many times and analysis, when the diameter of spheroid during less than 30cm, body explodes under non-perpendicular state, it is not clearly that the fire extinguishing effect of the ellipsoid shape shock wave of its generation is improved with respect to prior art, only have when sphere diameter is 30～32cm, this body explodes under non-perpendicular state, and its fire extinguishing effect is just more obvious with respect to prior art.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Among the figure, 1-Delay Tube parts, 2-band detonator part, 3-master's charge tube, 4-fire-fighting bomb for forest, 5-protective sleeve, 6-flame arrest explosive.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Embodiment 1:Referring to Fig. 1, a kind of fire-fighting bomb for forest center booster, comprise and fill flame arrest explosive 6, the main charge tube 3 of circular tube shaped, it is the spheroid of 30～32cm that main charge tube 3 is provided with the diameter that is communicated with it, the axle center of described spheroid and main charge tube 3 is on same straight line, and the density of main charge tube 3 interior flame arrest explosives is not less than 0.6g/cm
3Be communicated with it spheroid owing to being provided with in the main charge tube 3 of connection, this is so that the shock wave shape that the body explosion time produces is the ellipsoid shape near ball, simultaneously spheroid makes also that the flame arrest explosive is more concentrated to be distributed in around it, thus body explosion time no matter body whether vertically can both give play to largely the fire extinguishing effectiveness of fire extinguisher bomb.
Fire-fighting bomb for forest center booster generally comprises the main charge tube 3 that is communicated with successively; band detonator part 2; Delay Tube parts 1 and the protective sleeve 5 that is installed in Delay Tube parts 1 periphery; be packaged with flame arrest explosive 6 in the main charge tube 3; bring into play more possibly its fire extinguishing effect in order to make fire-fighting bomb for forest; flame arrest explosive 6 density of fire-fighting bomb for forest master charge tube 3 interior encapsulation are generally larger, and the applicant determines on the basis of constantly test, analysis and judgement, when flame arrest explosive 6 density are not less than 0.6g/cm
3The time, the fire extinguishing effect of fire-fighting bomb for forest can be brought into play largely.In actual production process, for reaching, the density that makes main charge tube 3 interior flame arrest explosives 6 is not less than 0.6g/cm
3Standard, flame arrest explosive 6 need to be compressed in the main charge tube 3, and flame arrest explosive 6 is integrally formed with main charge tube 3.
, with fire extinguisher bomb body explosion time under non-perpendicular state its fire extinguishing effectiveness is brought into play for to a greater degree, preferred described spheroid is two, and along the axial alternate setting of main charge tube.
Embodiment 2:Referring to Fig. 2, a kind of fire-fighting bomb for forest 4, comprise the center booster, this center booster comprises fills flame arrest explosive 6, the main charge tube 3 of circular tube shaped, it is the spheroid of 30～32cm that main charge tube 3 is provided with the diameter that is communicated with it, and the axle center of spheroid and main charge tube 3 is on same straight line, and the density of main charge tube 3 interior flame arrest explosives 6 is not less than 0.6g/cm
