Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a fire extinguishing and explosion suppression device used in inflammable and explosive compartments of weapon equipment. Background Art

[0002] At present, my country's fire extinguishing and explosion suppression system mainly uses Halon 1301 fire extinguishing agent, which has an ODP value of 12 and will damage the ozone layer, and has been banned worldwide; the current mainstream gas fire extinguishing agent heptafluoropropane has a global warming potential (GWP) of 3800, with a significant greenhouse effect and low fire extinguishing efficiency, and is no longer suitable for use in fire extinguishing and explosion suppression systems. Therefore, we actively develop a fire extinguishing and explosion suppression device that can replace Halon 1301, a fire extinguishing and explosion suppression device that is more environmentally friendly, has better explosion suppression effect, and is less toxic.

[0003] At present, there is a fire extinguishing and explosion suppression device for the crew compartment of an armored vehicle (CN115025416A). When the explosion suppression bottle receives a fire indication signal from an optical detector, the control box starts the electric squib, which pierces the positive arch sealing diaphragm. The positive arch sealing diaphragm is affected by the huge pressure difference between the inside of the bottle body and the external environment. The agent in the bottle body is instantly torn through the rupture of the arch sealing diaphragm and expands the rupture to spray outward. After passing through the upper valve body and the nozzle seat in turn, it immediately hits the inner cone surface of the nozzle, is emitted outward through the inner cone surface, and then hits the screen of the straight section inside the nozzle, thereby realizing the atomization function of the liquid fire extinguishing agent.

[0004] Although the fire extinguishing and explosion suppression device of the above structure can realize the atomization function of the liquid fire extinguishing agent, the screen will increase the spraying time, resulting in low fire extinguishing efficiency. Utility Model Content

[0005] The utility model aims to provide a fire extinguishing and explosion suppression device for an inflammable and explosive compartment of weapon equipment, so as to solve the problem of low fire extinguishing efficiency of the fire extinguishing and explosion suppression device in the prior art.

[0006] In order to solve the above technical problems, the utility model provides a fire extinguishing and explosion suppression device for inflammable and explosive compartments of weapons and equipment, comprising: a bottle body, having a accommodating chamber for accommodating a fire extinguishing agent; a nozzle, arranged at the bottle mouth of the bottle body, and provided with a plurality of injection holes arranged at the bottom and sides of the nozzle; a sealing plate, blocking between the bottle mouth and the inlet of the nozzle to separate the nozzle and the accommodating chamber; a destroying piece, arranged on the nozzle, and the destroying piece can exert an impact force on the sealing piece to destroy the sealing piece; a swirl core, arranged in the nozzle, and located between the plurality of injection holes and the inlet of the nozzle; a guide plate, arranged on a side of the nozzle away from the bottle body, and the fire extinguishing agent sprayed from the injection holes can collide with the guide plate and be sprayed circumferentially outward under the guidance of the guide plate.

[0007] By adopting the above technical solution, the utility model has the following beneficial effects:

[0008] By applying the technical solution of the utility model, when a fire occurs, the destroying part destroys the sealing sheet, and the fire extinguishing agent in the accommodating chamber is sprayed into the nozzle, and the fire extinguishing agent first collides with the swirl core in the nozzle for the first atomization. A part of the fire extinguishing agent after the first atomization is sprayed toward the side injection hole of the nozzle for the second atomization. The fire extinguishing agent sprayed from the injection hole is sprayed onto the guide plate for the third atomization. Another part of the fire extinguishing agent after the first atomization is sprayed toward the injection hole at the bottom of the nozzle, and the fire extinguishing agent sprayed from the injection hole is sprayed onto the guide plate for atomization. Under the guidance of the guide plate, the fully atomized fire extinguishing agent can be sprayed evenly toward the circumferential outside. The above structure has the following two advantages: First, the number of collisions of the fire extinguishing agent is increased, and effective droplets can be generated regardless of the ambient temperature, the atomization effect is good, and the explosion suppression effect is guaranteed. Second, due to the addition of the injection hole on the side, the overall area of ​​the injection outlet is increased, the kinetic energy loss caused by the fire extinguishing agent hitting the swirl core is reduced, the overall spraying speed is increased, and the spraying efficiency is high and the fire extinguishing efficiency is high.

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention will be further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 12 As shown, the fire extinguishing and explosion suppression device for the inflammable and explosive compartment of weapons and equipment of this embodiment comprises: a bottle body 10, a nozzle 20, a sealing sheet 30, a destroying member 40, a swirl core 50 and a guide plate 60. Among them, the bottle body 10 has a receiving chamber 11 for receiving the fire extinguishing agent; the nozzle 20 is arranged at the bottle mouth of the bottle body 10, and the nozzle 20 is provided with a plurality of injection holes 21 arranged at the bottom and the side of the nozzle 20; the sealing sheet 30 is blocked between the bottle mouth and the inlet of the nozzle 20 to separate the nozzle 20 from the receiving chamber 11; the destroying member 40 is arranged on the nozzle 20, and the destroying member 40 can exert an impact force on the sealing sheet 30 to destroy the sealing sheet 30; the swirl core 50 is arranged in the nozzle 20 and is located between the plurality of injection holes 21 and the inlet of the nozzle 20; the guide plate 60 is arranged on the side of the nozzle 20 away from the bottle body 10, and the fire extinguishing agent sprayed from the injection hole 21 can collide with the guide plate 60 and spray outward in the circumferential direction under the guidance of the guide plate 60.

[0030] By applying the technical solution of this embodiment, when a fire occurs, the destroying member 40 destroys the sealing sheet 30, and the fire extinguishing agent in the accommodating chamber 11 is sprayed into the nozzle 20, and the fire extinguishing agent first collides with the swirl core 50 in the nozzle 20 for the first atomization. A part of the fire extinguishing agent after the first atomization is sprayed toward the side injection hole 21 of the nozzle 20 for the second atomization. The fire extinguishing agent sprayed from the injection hole 21 is then sprayed onto the guide plate 60 for the third atomization. Another part of the fire extinguishing agent after the first atomization is sprayed toward the injection hole 21 at the bottom of the nozzle 20, and the fire extinguishing agent sprayed from the injection hole 21 is then sprayed onto the guide plate 60 for atomization. Under the guidance of the guide plate 60, the fully atomized fire extinguishing agent can be evenly sprayed toward the circumferential outside. The above structure has the following two advantages: First, the number of collisions of the fire extinguishing agent is increased, and effective droplets can be generated regardless of the ambient temperature, and the atomization effect is good, ensuring the explosion suppression effect. Second, since the side injection holes are added, the overall area of ​​the injection outlet is increased, compensating for the kinetic energy loss caused by the fire extinguishing agent hitting the swirl core, increasing the overall spraying speed, and achieving high spraying efficiency and high fire extinguishing efficiency.

[0031] It should be noted that, compared with the old Halon 1301 explosion suppression bottle, the fire extinguishing and explosion suppression device of this embodiment still includes the bottle body 10, the nozzle 20 and the guide plate 60, and the appearance structure does not need to be changed, and can be replaced in situ.

[0032] Preferably, in the present embodiment, the destroying member 40 is an electric squib. Of course, in other embodiments not shown in the drawings, the destroying member 40 may be any structure capable of destroying the sealing sheet 30 .

[0033] like Figure 6 , Figure 7 , Figures 10 to 12 As shown, in this embodiment, the rotary core 50 includes a core body 51 and an inclined plate 52 arranged on the outer side of the core body 51 in the circumferential direction. The inclined plate 52 divides the inner hole of the nozzle 20 into a plurality of atomization zones 53. A spray hole 21 is arranged on the side wall of the nozzle 20 corresponding to each atomization zone 53. The above structure realizes zoned pressurization, so that the fire extinguishing agent sprayed from the spray hole 21 on the side wall of the nozzle 20 has a high heating speed, a more uniform speed distribution, a better atomization effect, and a longer spray distance.

[0034] like Figure 6 , Figure 7 , Figures 10 to 12 As shown, in this embodiment, the core 51 is provided with a vertically arranged through hole 511, and the aperture of the through hole 511 gradually decreases in the direction from the bottle body 10 to the guide plate 60. The above structure can increase the area where the fire extinguishing agent collides with the hole wall of the through hole 511, thereby making the atomization effect of the axially sprayed fire extinguishing agent better.

[0035] Preferably, in this embodiment, the rotary core 50 is pressed into the nozzle 20 in an interference fit manner.

[0036] After long-term research, the inventors found that if the damaged sealing sheet 30 is pressed on the rotary core 50 under the action of gas pressure, the fire extinguishing agent may be blocked and cannot be sprayed out quickly. Figure 3 , Figure 4 and Fig.13 As shown, in this embodiment, the sealing sheet 30 has a destruction zone 1 and a connection zone 2 in its circumferential direction, and a pre-grooved groove 31 is provided on the destruction zone 1, and the destruction member 40 applies an impact force to the pre-grooved groove 31. Specifically, when a fire occurs, the destruction member 40 applies an impact force to the pre-grooved groove 31, so that the sealing sheet 30 is destroyed along a preset trajectory without generating fragments. Since there is no pre-grooved groove 31 at the connection zone 2, when the destruction zone 1 is destroyed by the impact, the connection zone 2 can provide a pulling force for the destruction zone 1, so that the connection zone 2 will not move upward to the rotary core 50, thereby preventing the flow port of the rotary core from being blocked, thereby ensuring that the fire extinguishing agent can be sprayed out quickly. The above-mentioned sealing sheet 30 can stably seal the agent, and at the same time, directional blasting is more reliable during spraying.

[0037] Preferably, if Fig.13 As shown, in this embodiment, the pre-groove 31 is a C-shaped groove, and the sealing sheet 30 explodes at the C-shaped groove position and adheres at the remaining positions to prevent the diaphragm from clogging the nozzle.

[0038] The bottle bodies of the fire extinguishing and explosion suppression devices currently in use are generally bulky carbon steel bottles, which are not conducive to lightweighting and storage. In order to solve the above problems, in this embodiment, the bottle body 10 is made of aluminum alloy material. The above structure reduces the weight of the bottle body 10 while meeting its functions, which is conducive to lightweighting and storage. In addition, the specifications and size of the bottle body 10 are consistent with the old Halon 1301 explosion suppression bottle, and can be replaced in the same position without reworking the equipment. It is efficient and economical, and has a long service life.

[0039] In this embodiment, carbon fiber is wound around the outer surface of the bottle body 10. The above structure makes the fire extinguishing and explosion suppression device stronger and also has the advantage of corrosion resistance.

[0040] like Figure 1 , Figures 3 to 5As shown, in this embodiment, the fire extinguishing and explosion suppression device further includes: a protective cover 70, the protective cover 70 is arranged at the bottom of the bottle body 10, the bottom of the protective cover 70 has an escape hole 71, the nozzle 20 is penetrated at the escape hole 71 and is sealed with the escape hole 71, a plurality of injection holes 21 are located outside the protective cover 70, and the destructive member 40 is located inside the protective cover 70. In the above structure, the protective cover 70 can protect the destructive member 40 to avoid damage caused by collision during storage. At the same time, since the protective cover 70 has the escape hole 71 for avoiding the nozzle 20, the existence of the protective cover 70 does not affect the injection of the fire extinguishing agent.

[0041] like Figure 1 , Figures 3 to 5 As shown, in this embodiment, the guide plate 60 includes a plate body 61 and a mounting ring 62 arranged relatively to each other, and a plurality of vertical plates 63 connected between the plate body 61 and the mounting ring 62, and the mounting ring 62 is fixedly arranged on the protective cover 70. Specifically, the fire extinguishing agent sprayed from the injection hole 21 will hit the plate body 61 to be atomized, and then diffuse to the surroundings under the guidance of the plate body 61, and finally be sprayed out from the openings between the plurality of vertical plates 63. The above-mentioned guide plate 60 can not only realize the functions of atomization and guidance, but also has little effect on the fire extinguishing agent diffused to the circumferential outside, thereby ensuring the fire extinguishing effect. Preferably, in this embodiment, there are three vertical plates 63 arranged at intervals in the circumferential direction, and the extension direction of the vertical surface of the vertical plate is consistent with the radial direction of the plate body 61. The above-mentioned structure enables the plate body 61 to be firmly connected to the mounting ring 62, while minimizing the obstruction to the fire extinguishing agent.

[0042] like Figure 1 , Figures 3 to 5 As shown, in this embodiment, the disc body 61 includes a disc and a guide cone which is arranged on the surface of the disc close to the nozzle 20 and protrudes upward. The guide cone plays the role of atomization and guidance.

[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the bottle body 10 includes a bottle body 12 and a mounting seat 13 disposed at the opening of the bottle body 12, the mounting seat 13 is fixedly connected to the nozzle 20, the mounting seat 13 is provided with an opening corresponding to the opening of the bottle body 12, the opening of the mounting seat 13 forms the opening of the bottle body 10, and the sealing sheet 30 is sandwiched between the mounting seat 13 and the nozzle 20. The above structure is simple and convenient for installing the sealing sheet 30.

[0044] like Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, in this embodiment, the mounting seat 13 is provided with a pressure switch 80, a pressure relief valve 90 and a filling valve 100, wherein the pressure switch 80 is used to monitor the pressure in the accommodating chamber 11, the pressure relief valve 90 is used to reduce the pressure in the accommodating chamber 11, and the filling valve 100 is used to fill the accommodating chamber 11 with a fire extinguishing agent. Specifically, any three side walls around the mounting seat 13 are provided with mounting holes, and the pressure switch 80, the pressure relief valve 90 and the filling valve 100 are respectively provided. When the pressure in the bottle increases and endangers the explosion suppression bottle, the pressure relief valve 90 can be used to perform a pressure relief operation to protect the safety of the explosion suppression bottle. The pressure switch 80 is used to monitor the pressure in the explosion suppression bottle. When the pressure in the bottle drops below a predetermined value due to triggering or leakage, the pressure switch provides a signal to inform the staff of the state in the fire extinguishing and explosion suppression device at this time. Of course, in other embodiments not shown in the figure, any one or two of the pressure switch 80, the pressure relief valve 90 and the filling valve 100 can also be provided on the mounting seat 13.

[0045] It should be noted that the pressure switch 80 , the pressure relief valve 90 and the filling valve 100 are all located in the protective cover 70 , and the protective cover 70 also plays a protective role for the pressure switch 80 , the pressure relief valve 90 and the filling valve 100 .

[0046] Preferably, if Figure 3 , Figure 5 , Figure 8 and Fig. 9 As shown, in this embodiment, the nozzle 20 is also provided with a release feedback toggle switch 140, which is used to timely feedback whether the fire extinguishing and explosion suppression device is in a spraying state. Specifically, when the destroying member 40 destroys the sealing sheet 30, the fire extinguishing agent in the accommodating chamber 11 is sprayed into the nozzle 20. The release feedback toggle switch 140 is opened under the action of the spraying pressure of the fire extinguishing agent to send an opening signal to the outside. After the control device receives the opening signal, it can be known that the fire extinguishing and explosion suppression device is in a working state at this time.

[0047] Preferably, if Figure 1 As shown, in this embodiment, a clamp 120 is provided on the bottle body 10, and the opening of the clamp 120 is tightened and fixed by bolts. By fixing it in the installation position with bolts, the fire extinguishing and explosion suppression device for the inflammable and explosive compartment of the weapon equipment can be fixedly placed.

[0048] Preferably, if Figures 1 to 4 and Figure 6As shown, in this embodiment, the bottle body 12 includes a container and a guard ring arranged around the neck of the container, and an aviation socket and a protective cover frame 130 are arranged on the guard ring, wherein the aviation socket passes through the guard ring, and the aviation socket located behind the guard ring is connected to the destroyer 40 and the pressure switch 80 through a wire, and the aviation socket exposed outside the guard ring is connected to the short-circuit protection cap 110. The short-circuit protection cap 110 protects the safety of the explosion-suppressing bottle when it is not in working state. When in working state, the aviation socket is connected to the external interface power supply, and the short-circuit protection cap 110 is installed on the protective cover frame 130.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
