Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing bomb technology, specifically to a directional fire extinguishing bomb and a vehicle directional fire extinguishing device. Background Technology

[0002] Fire extinguishing bombs work by spraying extinguishing agents through an explosion, thus extinguishing or suppressing fires.

[0003] There are two detonation methods for fire extinguishing grenades. One is the pull-type (also known as the active type), which explodes seven seconds after the pull cord is pulled, so it needs to be thrown quickly. The other is the ignition type (also known as the passive type), which ignites and explodes only after being forcefully thrown into the fire. Compared to the pull-type fire extinguishing grenades, the ignition type is safer to throw.

[0004] Currently, ignition-type fire extinguishing bombs include an outer shell, an expansion body located inside the outer shell, a fire extinguishing agent filled between the outer shell and the expansion body, a fuse for detonating the expansion body and extending to the outside of the outer shell, and an isolation sleeve for isolating the fuse and the fire extinguishing agent. When the fuse is ignited, it detonates the expansion body, causing it to burst open. The instantaneous increase in gas pressure inside the outer shell causes it to burst open, releasing the fire extinguishing agent to extinguish the fire.

[0005] In addition to being thrown, ignition-type fire extinguishing bombs can also be pre-suspended near targets with fire hazards. When the flames reach the ignition-type fire extinguishing bomb, it will detonate and extinguish the fire.

[0006] In the method of using ignition-type fire extinguishing bombs suspended in the air, the ignition-type fire extinguishing bombs droop due to their own weight, which causes them to not be able to face the target object with fire hazards directly. Therefore, they cannot achieve directional fire extinguishing, and the accuracy of fire extinguishing needs to be improved. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a directional fire extinguishing bomb and a vehicle-oriented directional fire extinguishing device. This invention enables directional fire extinguishing, thereby improving the accuracy of fire suppression.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A directional fire extinguishing grenade includes an ignition-type fire extinguishing grenade, a fixed base, and a mounting base. The fixed base has an opening groove on one side, and the ignition-type fire extinguishing grenade is placed in the opening groove. The mounting base has two adjusting plates, and the fixed base is located between the two adjusting plates. Each adjusting plate has an adjusting hole, and an adjusting shaft is installed in the adjusting hole. The adjusting shaft is rotatably and movablely engaged with the adjusting hole. The adjusting shaft is fixedly connected to the side of the fixed base. A locking element is provided on the adjusting shaft, and the adjusting plate is clamped between the locking element and the fixed base.

[0010] Furthermore, the adjustment hole is a cross-shaped hole.

[0011] Furthermore, the adjusting shaft is a threaded shaft, and the locking element is a nut, which is threadedly connected to the threaded shaft.

[0012] Furthermore, the ignition-type fire extinguishing bomb includes an outer shell, an expansion body inside the outer shell, a ignition wire connected to the expansion body, the ignition wire extending to the outside of the outer shell, an isolation sleeve fitted over the portion of the ignition wire inside the outer shell, one end of the isolation sleeve being connected to the inner wall of the outer shell, the other end of the isolation sleeve being connected to the expansion body, and a fire extinguishing agent being filled between the outer shell and the expansion body.

[0013] Furthermore, the inflatable body is either a firecracker or a compressed airbag.

[0014] Furthermore, the ignition wire is provided in several parts, with the portion of the ignition wire extending out of the housing located on each outer side wall of the housing extending out of the opening slot.

[0015] Furthermore, the portion of the ignition wire extending out of the outer casing is encapsulated.

[0016] A vehicle-oriented fire extinguishing device includes an engine compartment, wherein the engine compartment is provided with the aforementioned directional fire extinguishing projectile.

[0017] This utility model has the following beneficial effects:

[0018] 1. When the locking mechanism is released, the adjusting shaft can rotate and move within the adjusting hole, and the fixed seat installed with the adjusting shaft can also rotate and move, thus changing the orientation and position of the ignition-type fire extinguishing bomb 1 within the fixed seat to adapt to targets with fire hazards in different locations. When the locking mechanism is locked, the fixed seat 2 and the ignition-type fire extinguishing bomb 1 are stabilized in the adjusted orientation. When the ignition-type fire extinguishing bomb 1 detonates, it explodes outward from the opening slot 21, achieving directional fire extinguishing, which helps improve fire extinguishing accuracy and operational flexibility.

[0019] 2. By using the cross-shaped hole as an adjustment hole, the range of movement of the adjustment shaft within the cross-shaped hole can be increased. This increases the adjustment range of the fixed base in the left, right, up, and down positions, thereby increasing the adjustment range of the ignition-type fire extinguishing bomb located within the fixed base in the left, right, up, and down positions. This allows the ignition-type fire extinguishing bomb to adapt to the location of targets with fire hazards, improving the adaptability of the directional fire extinguishing bomb.

[0020] 3. By using a threaded rod as the adjusting shaft and a nut as the locking element, material sourcing is convenient, the structure is simplified, and adjustment is easy. Tightening the nut outwards increases the gap between the nut and the fixed seat, allowing the threaded rod to move and rotate within the adjusting hole, thus releasing the nut's locking effect. Reverse tightening of the nut re-clamps the adjusting plate between the nut and the fixed seat, preventing the threaded rod from moving or rotating within the adjusting hole, thus restoring the locking function.

[0021] 4. The overall structure of this utility model's directional fire extinguishing bomb is simple and reliable, easy to assemble, and convenient to use.

[0022] 5. When there is a fire near the ignition-type fire extinguishing bomb and the fuse is ignited, the ignition-type fire extinguishing bomb provided by this utility model can self-detonate to extinguish the fire without the need for manual detonation, making fire extinguishing more timely and faster, so as to control the fire more quickly.

[0023] 6. The use of an encapsulation structure can improve the moisture-proof effect of the fuse. When the encapsulation structure comes into contact with an open flame, it melts quickly, exposing the fuse, which is then ignited, thus improving the overall reliability of the ignition-type fire extinguishing bomb.

[0024] 7. By setting multiple ignition wires and distributing them on multiple outer surfaces of the outer casing; or by wrapping several ignition wires around the outer casing, the coverage area of ​​the ignition wires can be increased so that the ignition wires can be ignited in multiple directions on the outer casing, thereby improving the sensitivity of the ignition-type fire extinguishing bomb.

[0025] 8. By installing directional fire extinguishing bombs in the engine compartment of a vehicle, fires in the engine compartment can be extinguished in a timely manner, suppressing the fire and providing valuable time for the people inside the vehicle to get out and escape.

[0038] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Example 1:

[0040] See Figure 2 , Figure 3 and Figure 6 The directional fire extinguishing bomb includes an ignition-type fire extinguishing bomb 1, a fixing base 2, and a mounting base 3.

[0041] See Figure 2 An opening slot 21 is provided on one side of the fixing base 2. By inserting one end of the ignition-type fire extinguishing bomb 1 into the opening slot 21, the ignition-type fire extinguishing bomb 1 and the opening slot 21 are interference-fitted, allowing the fixing base 2 to stably accommodate the ignition-type fire extinguishing bomb 1. The fixing base 2 can be made of steel. When the ignition-type fire extinguishing bomb 1 detonates, the fixing base 2 will not explode, allowing the ignition-type fire extinguishing bomb 1 to detonate outward from the opening slot 21, so that the area of ​​the fixing base 2 with the opening slot 21 is extinguished by the ignition-type fire extinguishing bomb 1.

[0042] See Figure 2 and Figure 3The mounting base 3 is also equipped with two adjusting plates 31, which are integral with the mounting base 3. Both adjusting plates 31 have adjusting holes. The mounting base 3 can also be made of steel. The fixed base 2 is located between the two adjusting plates 31. An adjusting shaft is welded and fixed to the outer wall of the fixed base 2 facing the adjusting plate 31. The adjusting shaft is located in the adjusting hole and has a locking element. The adjusting plate 31 is clamped between the locking element and the fixed base 2.

[0043] When the locking mechanism is released, the adjusting shaft can rotate and move within the adjusting hole. The fixed base 2, welded and fixed to the adjusting shaft, also rotates and moves, changing the orientation and position of the opening slot 21 on the fixed base 2. This, in turn, changes the orientation and position of the ignition-type fire extinguishing bomb 1 located within the opening slot 21, adapting to targets with fire hazards in different locations. This enables directional fire suppression, improving fire suppression accuracy and operational flexibility. When the locking mechanism is relocked, the fixed base 2 and the ignition-type fire extinguishing bomb 1 are stabilized in their adjusted positions.

[0044] See Figure 2 and Figure 6 In this embodiment 1, the adjusting hole is a cross hole 311, the adjusting shaft is a threaded rod 22, and the locking element is a nut 23, which is threadedly connected to the threaded rod 22. By screwing the nut 23 outward, the gap between the nut 23 and the fixed seat 2 is increased, allowing the threaded rod 22 to move and rotate within the cross hole 311, thus releasing the locking effect of the nut 23. By tightening the nut 23 in the opposite direction, the adjusting plate 31 is clamped again by the nut 23 and the fixed seat 2, preventing the threaded rod 22 from moving and rotating within the cross hole 311, thus restoring the locking effect.

[0045] The working principle of the directional fire extinguishing bomb in Example 1 is as follows:

[0046] First, the mounting base 3 is fixedly installed on a facility near the target object where there is a fire hazard.

[0047] Secondly, by screwing the nut 23 outward, the gap between the nut 23 and the fixed seat 2 increases. At this time, the threaded rod 22 can move and rotate within the cross hole 311.

[0048] Then, move the threaded rod 22 in the cross hole 311 so that the fixed seat 2 moves together with the threaded rod 22 and adjusts the fixed seat 2 to the required position; rotate the fixed seat 2 with the axis of the threaded rod 22 as the rotation center and adjust the fixed seat 2 to the required angle so that the ignition fire extinguishing bomb 1 in the fixed seat 2 can be directed toward the target object with fire hazard.

[0049] Finally, tighten the nut 23 again. The gap between the nut 23 and the fixed seat 2 is reduced. The adjusting plate 31 located between the nut 23 and the fixed seat 2 is clamped again by the nut 23 and the fixed seat 2. At this time, the position and angle of the fixed seat 2 are fixed, thus completing the angle and position adjustment of the fixed seat 2.

[0050] When the target object catches fire, the ignition-type fire extinguishing bomb 1, which is directed towards the target object, can be detonated by the target object. When the ignition-type fire extinguishing bomb 1 explodes, the fire extinguishing agent 15 inside the ignition-type fire extinguishing bomb 1 is sprayed onto the target object, thereby achieving directional fire extinguishing.

[0051] exist Figure 7 The diagram illustrates six different positions and angles of the fixed base 2.

[0052] See Figure 7 In Figure (a), the threaded rod 22 is located at the leftmost end of the cross hole 311, and the opening slot 21 of the fixing seat 2 faces horizontally to the right, and the ignition-type fire extinguishing bomb 1 is also set horizontally to the right. At this time, it is suitable for directional fire extinguishing of targets located to the horizontal right of the ignition-type fire extinguishing bomb 1.

[0053] See Figure 7 In Figure (b), the threaded rod 22 is located at the rightmost end of the cross hole 311, and the opening slot 21 of the fixing seat 2 faces horizontally to the right, and the ignition-type fire extinguishing bomb 1 is also set horizontally to the right. At this time, it is suitable for directional fire extinguishing of targets located to the horizontal right of the ignition-type fire extinguishing bomb 1. Unlike Figure (a), the ignition-type fire extinguishing bomb 1 in Figure (b) can get closer to the target.

[0054] See Figure 7 In Figure (c), the threaded rod 22 is located at the top of the cross hole 311, and the opening slot 21 of the fixing seat 2 faces vertically downwards, and the ignition-type fire extinguishing bomb 1 is also set vertically downwards. At this time, it is suitable for directional fire extinguishing of the target object located directly below the ignition-type fire extinguishing bomb 1.

[0055] See Figure 7 In Figure (d), the threaded rod 22 is located at the bottom of the cross hole 311, and the opening slot 21 of the fixing seat 2 faces vertically downwards, as does the ignition-type fire extinguishing bomb 1. This configuration is suitable for directional fire extinguishing of targets located directly below the ignition-type fire extinguishing bomb 1. Unlike Figure (c), the ignition-type fire extinguishing bomb 1 in Figure (d) can get closer to the target.

[0056] See Figure 7 In Figure (e), the threaded rod 22 is located at the bottom of the cross hole 311, the opening slot 21 of the fixing seat 2 faces downward to the right, and the ignition-type fire extinguishing bomb 1 also faces downward to the right. At this time, it is suitable for directional fire extinguishing of the target object located to the lower right of the ignition-type fire extinguishing bomb 1.

[0057] See Figure 7In Figure (f), the threaded rod 22 is located at the bottom of the cross hole 311, the opening slot 21 of the fixing seat 2 faces downward to the left, and the ignition-type fire extinguishing bomb 1 also faces downward to the left. At this time, it is suitable for directional fire extinguishing of the target object located to the lower left of the ignition-type fire extinguishing bomb 1.

[0058] Based on the working principle described above in Embodiment 1, it can be seen that Embodiment 1 has the following effects:

[0059] First, when the locking mechanism is released, the adjusting shaft can rotate and move within the adjusting hole, and the fixed base 2, which is installed with the adjusting shaft, can also rotate and move. This allows the orientation and position of the ignition-type fire extinguishing bomb 1 within the fixed base 2 to adapt to targets with fire hazards in different locations. When the locking mechanism is locked, the fixed base 2 and the ignition-type fire extinguishing bomb 1 are stabilized in the adjusted positions. When the ignition-type fire extinguishing bomb 1 detonates, it explodes outward from the opening slot 21, achieving directional fire extinguishing and improving fire extinguishing accuracy and operational flexibility.

[0060] Secondly, by using the cross hole 311 as an adjustment hole, the range of movement of the adjustment shaft within the cross hole 311 can be increased. This increases the adjustment range of the fixed base 2 in the left, right, up, and down positions, thereby also increasing the adjustment range of the ignition-type fire extinguishing bomb 1 located within the fixed base 2 in the left, right, up, and down positions. This allows the ignition-type fire extinguishing bomb 1 to adapt to the location of the target object with a fire hazard, improving the adaptability of the directional fire extinguishing bomb in this embodiment 1.

[0061] Third, by using the threaded rod 22 as the adjusting shaft and the nut 23 as the locking element, it is convenient to source materials, simplify the structure, and facilitate adjustment.

[0062] Fourth, the directional fire extinguishing bomb of this embodiment 1 has a simple and reliable overall structure, is easy to assemble, and is convenient to use.

[0063] Example 2:

[0064] This embodiment 2 provides a specific structure of the ignition-type fire extinguishing bomb 1 in embodiment 1.

[0065] See Figure 4 and Figure 5 The ignition-type fire extinguishing bomb 1 includes a casing 11, an expansion body, a ignition wire 13, an isolation sleeve 14, and a fire extinguishing agent 15. The casing 11 contains an expansion body, on which the ignition wire 13 is mounted, extending to the outside of the casing 11. The space between the casing 11 and the expansion body is filled with the fire extinguishing agent 15. The portion of the ignition wire 13 inside the casing 11 is fitted with an isolation sleeve 14, which separates the ignition wire 13 from the fire extinguishing agent 15. One end of the isolation sleeve 14 abuts against the expansion body, and the other end abuts against the inner wall of the casing 11.

[0066] See Figure 1 The outer casing 11 includes a shell 111 and a cover 112. The top surface of the shell 111 is open, and the shell 111 is used to accommodate the expansion body, the isolation sleeve 14, and the extinguishing agent 15. The cover 112 has a through hole in the middle for the ignition wire 13 to pass through. Both the shell 111 and the cover 112 can be made of flame-retardant plastic. When both the shell 111 and the cover 112 are made of flame-retardant plastic, the cover 112 can be bonded to the shell 111 with transparent polyolefin adhesive, which is a special adhesive for bonding various plastics. More specifically, the flame-retardant plastic can be made of phenolic or urea-formaldehyde plastic. Phenolic and urea-formaldehyde plastics are difficult to burn and do not burn when removed from the ignition source. By using flame-retardant plastic, the premature leakage of the extinguishing agent 15 by the outer casing 11 before the expansion body explodes can be avoided, which would reduce the spray range of the extinguishing agent 15 and thus the extinguishing range.

[0067] See Figure 4 and Figure 5 The inflator can be either a firecracker 121 or a compressed air bag 122. When the inflator explodes, the air pressure inside the outer shell 11 increases instantaneously, causing the outer shell 11 to burst and the extinguishing agent 15 inside to be sprayed out. Using a firecracker 121 or a compressed air bag 122 as the inflator is convenient in terms of procurement and manufacturing the entire directional fire extinguishing projectile. When using a compressed air bag 122 as the inflator, the compressed air bag 122 refers to a rubber bag filled with compressed air.

[0068] When using firecracker 121 as the inflator, the fuse of firecracker 121 extends to the outside of outer casing 11 as fuse 13. When using compressed air bag 122 as the inflator, one end of fuse 13 is tied to the surface of compressed air bag 122, or one end of fuse 13 is glued to the surface of compressed air bag 122. When glued, transparent tape 17 can be used. The other end of fuse 13, away from compressed air bag 122, extends to the outside of outer casing 11.

[0069] The isolation sleeve 14 is also made of flame-retardant plastic.

[0070] Extinguishing agent 15 can be dry powder extinguishing agent 15.

[0071] The working principle of the ignition-type fire extinguishing bomb 1 in this embodiment 2 is as follows:

[0072] When a fire breaks out near the ignition-type fire extinguishing bomb 1, the flames ignite the fuse 13, which gradually burns. When the fuse 13 burns to the inside of the outer casing 11 but has not yet come into contact with the expansion body, the isolation sleeve 14 prevents the extinguishing agent 15 from extinguishing the fuse 13, ensuring that the fuse 13 burns smoothly to the expansion body. When the fuse 13 burns to the expansion body, the expansion body bursts open, and the air pressure inside the outer casing 11 increases instantaneously, causing the outer casing 11 to burst open and the extinguishing agent 15 inside the outer casing 11 to be sprayed out to extinguish the fire.

[0073] Based on the working principle described above in Embodiment 2, it can be seen that the ignition-type fire extinguishing bomb 1 provided in Embodiment 2 has the following advantages: when there is a fire near the ignition-type fire extinguishing bomb 1 and the fuse 13 is ignited, the ignition-type fire extinguishing bomb 1 can self-detonate to extinguish the fire without the need for manual detonation by personnel, making the fire extinguishing more timely and rapid, so as to control the fire situation more quickly.

[0074] Based on the aforementioned ignition-type fire extinguishing bomb 1, further improvements can be made, see [link to relevant documentation]. Figure 1 and Figure 2 The portion of the ignition wire 13 extending out of the outer casing 11 is encapsulated by a tubular structure 16, which fits over the portion of the ignition wire 13 extending out of the outer casing 11. The encapsulation structure 16 can be made of wax or a polyethylene plastic tube. The use of the encapsulation structure 16 improves the moisture resistance of the ignition wire 13. When the wax or polyethylene plastic comes into contact with an open flame, it melts rapidly, exposing the ignition wire 13, which is then ignited, thus improving the overall reliability of the ignition-type fire extinguishing bomb 1.

[0075] Example 3:

[0076] This embodiment 3 is an improvement upon embodiment 2:

[0077] See Figure 8 Four ignition wires 13 are provided, with one ignition wire 13 attached to each outer wall of the housing 11 outside the opening slot 21. To attach the ignition wires 13 to the outer wall of the housing 11, adhesive (e.g., transparent tape 17) can be used to stick the end of the ignition wire 13 to the outer wall of the housing 11. When the ignition wires 13 are wrapped with the encapsulation structure 16, the ignition wires 13 wrapped with the encapsulation structure 16 can also be stuck to the outer wall of the housing 11 with transparent tape 17.

[0078] By setting multiple ignition wires 13 and distributing them on multiple outer surfaces of the outer casing 11, the coverage of the ignition wires 13 can be increased so that the ignition wires 13 can be ignited in multiple directions on the outer casing 11, thereby improving the sensitivity of the ignition-type fire extinguishing bomb 1.

[0079] Alternatively, by wrapping several ignition wires 13 around the outer casing 11, the coverage of the ignition wires 13 can be increased, and the ignition wires 13 can be easily ignited in multiple directions on the outer casing 11, which also improves the sensitivity of the ignition-type fire extinguishing bomb 1.

[0080] Example 4:

[0081] A vehicle-mounted directional fire suppression system, including an engine compartment. The engine compartment is equipped with a directional fire suppression projectile as described in Embodiment 1, Embodiment 2, or Embodiment 3.

[0082] When installing directional fire extinguishing bombs in the engine compartment, multiple directional fire extinguishing bombs can be installed. The mounting base 3 of the directional fire extinguishing bomb is fixedly installed on the engine compartment hood or the inner wall of the engine compartment. The ignition-type fire extinguishing bomb 1 of the directional fire extinguishing bomb is oriented towards the location prone to fire (such as fuel tank, fuel pump, fuel filter, pipeline connection, etc.). When a fire breaks out in the engine compartment, the directional fire extinguishing bombs installed in the engine compartment can extinguish the fire in a targeted manner.

[0083] By installing directional fire extinguishing bombs in the engine compartment of a vehicle, fires inside the engine compartment can be extinguished in a timely manner, suppressing the fire and providing valuable time for the people inside the vehicle to get out and escape.

[0084] Furthermore, the vehicle-oriented fire extinguishing device of Embodiment 4 also includes a driver's cab, in which a directional fire extinguishing bomb as described in Embodiment 1, Embodiment 2, or Embodiment 3 is installed. When installing the directional fire extinguishing bomb in the driver's cab, several directional fire extinguishing bombs can be installed, with the ignition-type fire extinguishing bomb 1 facing a location prone to ignition (such as the bottom of the steering wheel). When a fire breaks out in the driver's cab, the directional fire extinguishing bomb installed in the driver's cab can directionally extinguish the fire inside the cab.

[0085] As can be seen from the above introduction, by installing directional fire extinguishing bombs in the driver's cab of a vehicle, fires inside the cab can be extinguished in a timely manner, suppressing the fire and providing valuable time for the people inside the vehicle to get out and escape.

[0086] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
