Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a helicopter-lifted blasting fire-extinguishing bomb. Background Art

[0002] It is known that water-aerosol-fog has particularly good fire-extinguishing efficiency. This is partly because the center of the flame is extinguished due to the aerosol-fog. Additionally, through the evaporation of water in the form of very fine fog, heat can also be absorbed from the flame. It is known from WO97 / 06858A1 that a helicopter can be used to transport a water-filled blasting bag and drop it above the flame. When the blasting bag falls freely, the blasting charge in the bag will detonate. Due to the pressure generated thereby, the blasting bag will be destroyed and the water contained therein will suddenly be converted into aerosol-fog.

[0003] In the prior art, since blasting for fire extinguishing requires controlling the explosion time of the fire-extinguishing bomb to ensure that it explodes when it reaches the predetermined position, thereby maximizing the fire-extinguishing effect of the fire-extinguishing bomb. However, this requires adding an explosion controller for the fire-extinguishing bomb, but the controller cannot effectively adapt and adjust to different fire intensities, which affects the fire-extinguishing effect of the fire-extinguishing bomb.

[0004] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to make improvements. Content of the Utility Model

[0018] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] See Figures 1 to 4 , the present utility model provides a helicopter - hoisted blasting fire - extinguishing bomb. The helicopter - hoisted blasting fire - extinguishing bomb includes a capsule body 1 for containing fire - extinguishing materials. A plurality of hoisting belts 2 are arranged outside the capsule body 1 to ensure that when in need of use, the helicopter can hoist the capsule body 1 through the hoisting belts 2. At the same time, when not in use, the capsule body 1 can be folded and contracted, facilitating the transportation of the capsule body 1. An inlet 3 for injecting fire - extinguishing materials is opened on the capsule body 1, facilitating the injection of fire - extinguishing liquid through the inlet 3; a column 5 fixedly arranged on the capsule body 1 stores blasting materials through the column 5 to ensure the explosion and fire - extinguishing effect of the fire - extinguishing bomb. The capsule body 1 is wound around the outer edge of the column 5, and blasting materials are arranged inside the column 5. When the entire capsule body 1 falls to a predetermined position, the blasting materials are triggered to explode, so that the fire - extinguishing materials inside the capsule body 1 are scattered and atomized in an explosive manner, thereby extinguishing the fire in a large area and optimizing the fire - extinguishing effect.

[0020] Preferably, an inner tube 8 is arranged inside the column 5 of the present utility model. A filling space 6 is arranged between the outer wall of the inner tube 8 and the column 5. By setting the filling space 6, the normal filling of the internal blasting materials is ensured, and at the same time, it is ensured that the trigger 10 can contact the blasting materials to trigger the blasting materials. A trigger 10 for triggering the blasting materials is installed at the top of the column 5. When the trigger 10 contacts the blasting materials (prior art, not elaborated further), it is ensured that the fire - extinguishing materials inside the capsule body 1 can be exploded and atomized to achieve the fire - extinguishing effect. A temperature - sensing cover 4 is screwed to the top of the column 5, and the trigger 10 is slidably connected inside the temperature - sensing cover 4. When the temperature - sensing cover 4 is heated, it pushes the trigger 10 to slide towards the bottom of the temperature - sensing cover 4. By detecting the temperature around through the temperature - sensing cover 4, when reaching a predetermined temperature, the trigger 10 can contact the blasting materials, thereby triggering the explosion of the blasting materials to achieve the fire - extinguishing effect.

[0021] In addition, a sliding groove is provided inside the temperature sensing cover 4 of the utility model, and the trigger member 10 is slidably connected to the inside of the sliding groove. A temperature sensing expansion material 9 is provided between the trigger member 10 and the sliding groove. When the temperature sensing cover 4 gradually approaches the fire source, the fire source heats the temperature sensing cover 4 to expand the temperature sensing expansion material. An isolation layer is provided at the bottom of the temperature sensing cover 4. When the trigger member 10 moves to the sealing edge, the isolation layer is cut. When the blasting material is not triggered, the isolation layer at this time isolates the trigger member 10 from the blasting material to prevent abnormal explosion.

[0022] Furthermore, the bottom outer wall of the bag body 1 of the utility model is fixedly provided with a fixing plate 11, and the fixing plate 11 fixes the positions of several lifting straps 2. The fixing plate 11 is provided with several slots 12 cooperating with the lifting straps 2. The lifting straps 2 are arranged inside the slots 12. The positions of the lifting straps 2 are fixed by the fixing plate 11 to prevent the lifting straps 2 from being misplaced, which affects the lifting and use of the bag body 1.

[0023] Better yet, the inner tube 8 of the utility model is provided with an air channel 7 inside, and the air channel 7 extends from the bottom of the bladder 1 to the top of the bladder 1. When the bladder 1 falls, the air flows through the air channel 7. At this time, the air is in full contact with the temperature sensing cover 4, thereby heating the temperature sensing expansion material 9, thereby pushing the trigger member 10 to gradually contact and trigger the blasting material, thereby achieving the blasting effect on the bladder 1.

[0024] In this embodiment, see Figures 1 to 4 When in use, first inject the fire extinguishing material into the interior of the bladder 1 through the inlet 3. The bladder 1 is stretched open by the force of the fire extinguishing material. After the injection is completed, the lifting belt 2 is hooked by the helicopter, and then the bladder 1 is lifted to a suitable position, and then the lifting belt 2 is released. At this time, the bladder 1 falls under the action of gravity, and the air passes through the air channel 7 to heat the temperature sensing cover 4. When the temperature reaches a predetermined value, the distance between the bladder 1 and the fire source meets the requirement, and then the trigger passes through the isolation layer under the action of the temperature sensing expansion material 9 to contact the blasting material, so that the blasting material explodes, and the fire extinguishing material is atomized and dispersed to extinguish the fire.

[0025] In summary, the present utility model provides a helicopter-lifted blasting fire extinguishing bomb, including: a capsule for containing fire extinguishing materials, with a plurality of lifting straps arranged outside the capsule to ensure that when in need of use, the helicopter can lift the capsule through the lifting straps, and at the same time when not in use, the capsule can be folded and contracted for easy transportation of the capsule. An inlet for injecting fire extinguishing materials is provided on the capsule to facilitate the injection of fire extinguishing liquid through the inlet; a column fixedly arranged on the capsule stores blasting materials to ensure the explosion fire extinguishing effect of the fire extinguishing bomb. The capsule is wound around the outer edge of the column, and blasting materials are arranged inside the column. When the entire capsule drops to a predetermined position, the blasting materials are triggered to explode, so that the fire extinguishing materials inside the capsule are scattered and atomized in an explosive manner, thereby extinguishing the fire in a large area and optimizing the fire extinguishing effect. In summary, the technical effect produced by the present utility model is that by setting an automatic temperature sensing structure, it is ensured that when the helicopter drops the fire extinguishing bomb to a predetermined position, the fire extinguishing bomb will automatically sense the temperature and trigger an explosion when reaching the predetermined temperature, thereby effectively controlling and extinguishing the fire.
