Detailed description of the invention
Be described in further detail below in conjunction with the explosion experiments method of drawings and Examples to a kind of fire-fighting bomb for forest of the present invention, but not as the foundation of any restriction done the present invention.
As shown in drawings, a kind of explosion experiments method of fire-fighting bomb for forest, described method comprises the steps:
The first step, stands on explosion center by the fire extinguisher bomb 2 filling fire fighting powder;
Second step, filling explosive and electric cap, connect exploding wire but not conducting;
3rd step, lights a torch 1;
4th step, adjusts to shooting state by high-speed camera and video camera, and sends ready password;
5th step, carries out the work of exploding wire continuity test, and sends ready password;
6th step, high-speed camera instrument operator sends detonates password and presses shooting push button, and staff hears ignition and detonation fire extinguisher bomb 1 after the password that detonates;
7th step, after fire extinguisher bomb 1 explosion, takes pictures to fire extinguisher bomb 1 remains, carries out test data record, and site clearing, explosion bulge test completes.
The explosion experiments method of a kind of fire-fighting bomb for forest of the present invention, wherein needs article: fire extinguisher bomb 4; High-speed camera 1; 1, video camera; Digital camera 1; Torch 50; Power line 400 meters; Tape measure 1 is (50 meters); And other aids.
Embodiment 1
Fire extinguisher bomb 1, explosive payload 23g, pencil length 520mm, pencil type: aluminum pipe; Pencil diameter G12 × 1.5mm; Cylindrical shell state: latticed; Charge positions: bottom-up; Dry powder type: common.All torches are all lighted, but before blast, the burning of some torch is insufficient, and the intensity of a fire is little, sees Fig. 2, tests and carries out to the 7th step by the above-mentioned first step.
Result of the test: body is blown uneven, dry powder is shed uneven, sheds more to the left, and have part dry powder not shed away in addition, ground is by packing phenomenon; Have 11 torches not extinguished, all have in torch position, 1m, 2m, 3m, 4m place and do not extinguish torch, major part is not extinguished torch and is concentrated on 1m and 2m place, does not extinguish torch simultaneously and concentrates on powder and shed less right side.
Fire extinguisher bomb explosive view is shown in that Fig. 3, torch extinguish situation map and see Fig. 4.
Embodiment 2
Fire extinguisher bomb 2, explosive payload 40g, pencil length 520mm, pencil type: aluminum pipe; Pencil diameter G14 × 1mm; Cylindrical shell state: latticed; Charge positions: bottom-up; Dry powder type: ultra-fine.All torches are all lighted.But before blast, the burning of some torch is insufficient, and the intensity of a fire is little, especially right side torch, is shown in Fig. 5, tests and carry out to the 7th step by the above-mentioned first step.
Result of the test: result of the test: body is blown comparatively even, dry powder is shed comparatively even, and dry powder is substantially all shed away, and there is not packing phenomenon on ground; Have 4 torches not extinguished, concentrate on 1m (1), 2m (2), 4m (1), except 1 of 4m place, all the other are all that flare is arranged at top, and bottom does not have.
Fire extinguisher bomb explosive view is shown in that Fig. 6, torch extinguish situation map and see Fig. 7.
Embodiment 3
Fire extinguisher bomb 3, explosive payload 56g, pencil length 520mm, pencil type: aluminum pipe; Pencil diameter G16 × 1mm; Cylindrical shell state: latticed; Charge positions: bottom-up; Dry powder type: common.Unignited with fire extinguisher bomb 1m place torch of being separated by, all the other are all lighted.The torch intensity of a fire is better, sees Fig. 8, tests and carry out to the 7th step by the above-mentioned first step.
Result of the test: body is blown comparatively even, dry powder is shed comparatively even, and dry powder is substantially all shed away, and there is not packing phenomenon on ground; There are 5 torches not extinguished, concentrate on 2m (3), 3m (1), 4m (1).
Fire extinguisher bomb explosive view is shown in that Fig. 9, torch extinguish situation map and see Figure 10.
Embodiment 4
Fire extinguisher bomb 4, explosive payload 72g, pencil length 520mm, pencil type: aluminum pipe; Pencil diameter G18 × 1mm; Cylindrical shell state: latticed; Charge positions: bottom-up; Dry powder type: common.Unignited with fire extinguisher bomb 1m place torch of being separated by, all the other are all lighted.The torch intensity of a fire is better, sees Figure 11, tests and carry out to the 7th step by the above-mentioned first step.
Result of the test: the torch at 3m place does not extinguish, the intensity of a fire is better, analyzes because fire extinguisher bomb is in blast process, the powder ball formed has certain altitude to limit in outside diffusion process, although bottom is effectively covered by powder and extinguishes, because top still has flare, cause by resume combustion.Torch two place at 4m place is double joint torch side by side, analysis may due to double joint side by side between torch gap not easily effectively covered by dust cloud, cause torch resume combustion.Although an other place is in the middle of dust cloud, dust cloud is thinner, causes not extinguishing.
Fire extinguisher bomb explosive view is shown in that Figure 12, torch extinguish situation map and see Figure 13.
Conclusion (of pressure testing):
1), under 20g dose, explode uneven, extinguishing effect is bad.
2) fire extinguisher bomb fire extinguishing has certain altitude to limit.Dust cloud height is about about 1m.
3) fire-fighting efficiency of ultra-fine dry powder is higher than common dry powder.The extinguishing effect of 8kg and the common dry powder of about 16kg very nearly the same.
4) explosive payload reach a certain amount of after, even if increase explosive payload again, extinguishing effect impact is little.62g and 75g is in the much the same situation of the torch intensity of a fire, and extinguishing effect is very nearly the same.
