Description

Technical Field

[0001] The present invention relates to the field of emergency firefighting, and in particular to an integrated emergency firefighting foam spraying device for a hazardous chemical storage tank area. Background Art

[0002] Storage tanks are crucial containers used in the petrochemical industry. Because they contain flammable and explosive hazardous chemicals, a fire can cause significant property damage and casualties. Therefore, firefighting foam sprinklers are often installed in storage tank areas to promptly contain the spread of fire and prevent further casualties and property damage.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the technical means for fire foam spraying. In order to make a more accurate comparison, for example, a Chinese patent with announcement number CN215653586U discloses a foam fire sprinkler head, including an installation threaded section, a connecting pipe head, a bracket and a funnel-shaped water hole, a glass body and a fire water pipe. When in use, the glass body will explode under high temperature. After the glass body shatters, water will rush out from the connecting pipe head downward, through the funnel-shaped water hole and the fire water pipe, and part of the water will fuse with the foaming powder through the water outlet hole when entering the foam combination pipe. The generated foam will continuously increase the pressure in the foam combination pipe. When it reaches a certain critical value, it will break through the pressure pump water sheet, thereby pumping the foam out. Part of the water flow and foam will spray around through the end cover hole, and part of the water flow and foam will pass through the bottom sealing cover and be sprayed to the bottom of the sprinkler head through the inclined surface and the water outlet gap, which can effectively solve the problem of dead corners in fire sprinkler fire extinguishing.

[0004] However, the above-mentioned spraying device still has some shortcomings in actual use: The above-mentioned device releases the seal on the connecting pipe head by the explosion and shattering of the glass body, so that the water in the fire-fighting pipe can flow out smoothly. However, in actual use, the direction of the explosion of the fragments of the glass body cannot be controlled after the thermal expansion of the glass body itself in a high-temperature environment. After the glass body explodes, it is likely to be retained and accumulated in the funnel-shaped water hole, causing the funnel-shaped water hole to be blocked, affecting the discharge rate of the water flow. Moreover, the method of unlocking the pipeline flow by the shattering of the glass body requires that the glass body or even the entire device needs to be replaced after one use, and its overall economic cost is relatively high.

[0005] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means for fire foam spraying. Summary of the Invention

[0010] Preferably, the side of the floating block away from the liquid medium is spaced apart from the mounting sleeve.

[0011] Preferably, a plurality of through holes are formed on a side of the mounting sleeve close to the pipe head.

[0012] Preferably, the upper limit of the connecting slide rod is provided with a connecting frame, and the connecting frame is provided with a driving rack passing through the limiting ring plate, the driving rack is engaged with a driven gear limitedly positioned on the limiting ring plate, and the driven gear is also engaged with a driven rack connected to the connecting block.

[0013] Preferably, a limiting guide rod with a bent structure is inserted on the limiting ring plate and the connecting frame for limiting positioning, and the bent section of the limiting guide rod abuts against the connecting frame.

[0014] Preferably, the connecting slide rod is connected to a driven rotating rod which is limitedly inserted on the limiting guide rod, and a spiral sliding groove is formed on the limiting guide rod for the driven rotating rod to slide.

[0015] Preferably, a through hole is formed on the connecting frame corresponding to the bent section of the limiting guide rod.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. The present invention uses the sliding cooperation between the connecting slide rod and the installation sleeve to drive the connecting plug to separate from the pipe head or drive the connecting plug to seal the pipe head, avoiding the use of fragile glass to unlock the pipe head and prevent glass fragments from clogging the pipe. At the same time, it has the characteristic of being reusable.

[0017] 2. The present invention achieves the limitation of the connecting plug in the normal state through the mutual cooperation between the limiting guide rod, the connecting frame and the connecting slide rod, thereby avoiding the accidental slippage of the connecting plug and the accidental spraying of the fire water in the pipe head. And through the cooperation between the limiting guide rod, the connecting frame, the driven rotating rod, the connecting slide rod and the floating block, the connecting plug can be normally unlocked to realize the spraying of fire foam after a fire occurs.

[0018] 3. The present invention cooperates with the installation sleeve, the storage bin, the float and the baffle, so that when a fire occurs, the liquid medium in the installation sleeve can be pressed into the storage bin for temporary storage, so that the liquid level in the installation sleeve moves down, thereby causing the connecting plug and the connecting slide rod to be further separated from the pipe head as a whole, increasing the distance between the connecting plug and the pipe head after separation, and avoiding the problem of affecting the efficiency of fire foam discharge.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 To the attached Figure 8 The embodiments of the present invention are described in detail.

[0030] The embodiment of the present application discloses an integrated emergency fire foam spraying device for a hazardous chemical storage tank area, which can solve the problem that the existing foam spraying device can only be used once and cannot be reused.

[0031] Example 1: Reference Figure 1 and Figure 2 As shown, an integrated emergency fire foam spraying device for a hazardous chemical storage tank area includes a pipe head 1, which is provided with a thread for connecting to a fire pipe. A connecting plug 10 is passed through the upper limit of the pipe head 1. A connecting frame 11 extends outward from one end of the pipe head 1 close to the connecting plug 10. A base plate 12 is provided at the end of the connecting frame 11 away from the pipe head 1. A telescopic end 2 is connected between the connecting plug 10 and the base plate 12 to control the sliding of the connecting plug 10 from the pipe head 1.

[0032] During use, in the initial state, the telescopic end 2 is extended to drive the connecting plug 10 to be inserted into the pipe head 1 to prevent the foam liquid in the fire-fighting pipe from being accidentally discharged. After a fire occurs in the tank area, the telescopic end 2 is used to control the connecting plug 10 to slide and separate from the pipe head 1. The foam liquid in the fire-fighting pipe is discharged from the pipe head 1 under the action of the pressure in the pipe and sprayed to the fire source, thereby achieving the effect of curbing the fire.

[0033] Reference Figures 2 to 4 As shown, the telescopic end 2 includes a mounting sleeve 20 restrained on the base plate 12, a connecting slide 21 slidably inserted into the mounting sleeve 20, a limiting ring plate 22 connected to the connecting plug 10 sleeved on the connecting slide 21, and a return spring 23 sleeved on the connecting slide 21, positioned between the mounting sleeve 20 and the limiting ring plate 22. As an optional embodiment, in the initial state, the return spring 23 can be in a stressed and compressed state to provide the limiting ring plate 22 and the connecting plug 10 with a tendency to always slide upward, so that the connecting plug 10 is fixedly inserted on the pipe head 1.

[0034] During use, after the pipe head 1 and the fire-fighting pipe are connected, the water pressure in the fire-fighting pipe acts on the connecting plug 10 inserted in the pipe, so that the connecting plug 10 has a tendency to move downward and separate from the pipe head 1 by the water pressure. The downward movement of the connecting plug 10 drives the limiting ring plate 22 and the connecting slide bar 21 to also slide downward, so that the connecting slide bar 21 slides relative to the mounting sleeve 20 and drives the return spring 23 to be compressed. After the fire is under control, the compressed return spring 23 pushes the connecting plug 10 to move downward. , driving the connecting slide rod 21, the limiting ring plate 22 and the connecting plug 10 to reset, so that the connecting plug 10 is reinserted into the pipe head 1 to block the pipe head 1. By installing the sleeve 20, the connecting slide rod 21, the limiting ring plate 22 and the connecting plug 10, the cooperation between the sleeve 20, the connecting slide rod 21, the limiting ring plate 22 and the connecting plug 10 effectively avoids the problem of the broken glass body easily clogging the pipeline when the glass body is conventionally used to unlock the pipe head 1. At the same time, after the fire is under control, the closed state of the pipe head 1 and the fire pipeline can be automatically restored, thereby improving the reuse rate of the device.

[0035] Reference Figure 3 and Figure 4 As shown, the connecting plug 10 includes a small end 100 inserted into the tube head 1 and a large end 101 abutting against the tube head 1, and a receiving cavity with one side open is formed between the large end 101 and the small end 100, and the limiting ring plate 22 is limitedly connected in the receiving cavity.

[0036] Reference Figure 3 and Figure 4 As shown, to enhance the stability of the device during use, the mounting sleeve 20 and the connecting slide 21 are axially aligned. One end of the connecting slide 21, inserted within the mounting sleeve 20, is connected to a float 24 limited within the mounting sleeve 20. A liquid medium is contained between the side of the float 24 facing away from the pipe head 1 and the inner wall of the mounting sleeve 20. During use, due to the inherent incompressibility of the liquid medium, the float 24 floats above the liquid medium within the mounting sleeve 20. The water pressure from the fire protection line applies a downward force to the connecting plug 10, the retaining ring 22, and the connecting slide 21, counteracting the upward buoyancy of the float provided by the liquid medium within the mounting sleeve 20. At this point, the buoyancy of the float in the water, the elastic restoring force of the compressed return spring 23, and the propulsion force applied to the connecting plug 10 by the water pressure in the fire protection line form a balanced state, effectively sealing the pipe head 1 and the fire protection line under normal conditions. This effectively alleviates the problem of excessive stress on the return spring 23, which can lead to elastic fatigue.

[0037] Further, refer to Figure 3 and Figure 4 As shown, the side of the float 24 away from the liquid medium is spaced apart from the mounting sleeve 20 to allow the float 24 to have a certain sliding range in the mounting sleeve 20 .

[0038] Reference Figure 2 and Figure 8 As shown, a plurality of through holes 25 are formed on one side of the mounting sleeve 20 close to the pipe head 1 to buffer the air pressure on the upper part of the floating block 24 in the mounting sleeve 20. The mounting sleeve 20 is preferably made of a heat-conducting material, and the liquid medium is preferably a low-boiling-point liquid.

[0039] During use, after the heat of the high-temperature flue gas is transferred to the mounting sleeve 20, the liquid medium in the mounting sleeve 20 is heated, which will cause the molecular movement of the liquid medium in the mounting sleeve 20 to accelerate, causing the pressure in the mounting sleeve 20 to rise. At this time, a number of through holes 25 are set on the side of the mounting sleeve 20 close to the pipe head 1, so that part of the pressure on the upper side of the floating block 24 in the mounting sleeve 20 can be quickly released, avoiding the problem of over-pressure explosion in the mounting sleeve 20. At the same time, the pressure relief through the through holes 25 makes the pressure on both sides of the floating block 24 have a significant difference, so as to ensure that the floating block 24 is driven by the pressure difference between the inside and outside of the mounting sleeve 20 to slide smoothly and stably.

[0040] Furthermore, refer to Figure 5 and Figure 6 As shown, the upper limit of the connecting slide rod 21 is provided with a connecting frame 26, and the connecting frame 26 is provided with a driving rack 260 that passes through the limiting ring plate 22. The driving rack 260 is engaged with a driven gear 261 that is limitedly positioned on the limiting ring plate 22, and the driven gear 261 is also engaged with a driven rack 262 connected to the connecting plug 10. The driving rack 260 and the driven rack 262 are arranged on both sides of the driven gear 261 to perform relative / opposite sliding motion.

[0041] During use, the temperature of the high-temperature smoke generated by the fire is transferred to the installation sleeve 20, causing the liquid medium in the installation sleeve 20 to expand due to the heat until it boils and produces steam. At this time, under the push of the rising steam, the floating block 24 in the installation sleeve 20 is driven to move upward, and the upward movement of the floating block 24 drives the connecting slide rod 21 to move upward. The upward movement of the connecting slide rod 21 drives the connecting frame 26 and the driving rack 260 to move upward synchronously. After the rack is driven to move upward, a relative position sliding effect is formed between it and the driven gear 261, driving the driven gear 261 to rotate. The rotation of the driven gear block drives the meshing driven rack 262 on the other side to slide synchronously, so that the driven rack 262 drives the connecting plug 10 to move downward as a whole, so that the connecting plug 10 can be separated from the pipe head 1.

[0042] Reference Figure 4 As shown, as an optional embodiment, in order to improve the stability of the connecting plug 10 when it is driven to slide by the driven rack 262, a plurality of driving racks, driven gears 261 and driven racks 262 can be correspondingly provided and evenly distributed circumferentially with the connecting slide rod 21 as the axis.

[0043] Reference Figure 5As shown, after the pipe head 1 is connected to the fire-fighting pipeline, the water pressure in the fire-fighting pipeline will always act on the connecting plug 10, so that the connecting plug 10 tends to separate downward from the pipe head 1, that is, the reset spring 23 will always be in a compressive load state, which is likely to cause fatigue of the reset spring 23 after long-term use. Therefore, in order to avoid fatigue of the reset spring 23, the reset spring 23 only needs to reset the connecting plug 10 after the connecting plug 10 is separated from the pipe head 1, that is, the reset spring 23 does not participate in the daily limiting process of the connecting plug 10. Based on this, a limiting guide rod 27 with a bending structure is inserted on the limiting ring plate 22 and the connecting frame 26, and the bent section of the limiting guide rod 27 is against the connecting frame 26.

[0044] During use, when water pressure acts on the connecting plug 10, causing the connecting plug 10 and the driven rack 262 to have a tendency to slide away from the pipe head 1, the sliding of the connecting frame 26 and the several connected driving racks 260 is limited by the limiting guide rod 27. After the driving rack 260 is limited, it limits the corresponding engaged driven rack, thereby limiting the sliding of the driven rack 262, preventing the connecting plug 10 and the driven rack 262 from being driven by water pressure to slide and separate from the pipe head 1.

[0045] Further, refer to Figure 6 and Figure 7 As shown, in order to release the limit on the connecting frame 26 when a fire occurs, a through hole 272 is formed on the connecting frame 26 corresponding to the bent section of the limit guide rod 27. When in use, the limit guide rod 27 is driven to rotate to correspond to the through hole 272. Under normal conditions, the bent section of the limit guide rod 27 and the through hole 272 are staggered and abut against the connecting frame 26 to limit the slippage of the connecting frame 26.

[0046] Reference Figure 6 and Figure 7 As shown, to drive the limiting guide rod 27 to rotate, the connecting slide 21 is connected to a driven rotating rod that is fixedly inserted into the limiting guide rod 27. A spiral groove 271 is formed on the limiting guide rod 27 for the driven rotating rod to slide. In the initial state, the connecting slide 21 is spaced apart from the connecting frame 26 to allow a certain amount of sliding movement of the connecting slide 21. The limiting guide rod 27 is rotationally restrained to the connecting frame 26 by a stop block (not shown), thereby limiting the sliding movement of the limiting guide rod 27.

[0047] During use, after a fire occurs, the heat of the high-temperature smoke is transferred to the liquid medium in the installation sleeve 20, driving the liquid medium to expand due to the heat until it boils. After the liquid medium expands, it drives the float block 24 and the connecting slide rod 21 to slide along the installation sleeve 20 toward the pipe head 1. The sliding of the connecting slide rod 21 drives the driven rotating rod to slide synchronously, and drives the driven rotating rod to slide along the spiral slide groove 271. At this time, since the limiting guide rod 27 is limited, the sliding driven rotating rod drives the limiting guide rod 27 to deflect through the spiral slide groove 271, so that the bent section on the limiting guide rod 27 rotates to correspond to the through hole 272, that is, the limit on the connecting frame 26 is released. At this time, under the action of water pressure, the connecting plug 10 can be driven to disengage from the pipe head 1, so that the fire foam can be sprayed at the fire.

[0048] Example 2: Reference Figure 8 As shown, on the basis of Example 1, the sliding of the connecting plug 10 is controlled by the mutual meshing transmission cooperation of the driving rack 260, the driven gear 261 and the driven rack 262 on the connecting plug 10, and since the driven gear 261 is limited on the connecting plug 10 and the limiting ring plate 22, and the space of the accommodating cavity on the connecting plug 10 is limited, the overall allowable relative sliding range of the driving rack 260 and the driven rack 262 is limited, that is, the sliding range of the connecting plug 10 driven by the driven rack 262 to separate from the pipe head 1 is limited. In this case, it is very likely that the connecting plug 10 will not move downward enough, so that the distance between the pipe head 1 and the connecting plug 10 is too small, resulting in difficulty in releasing water and foam in the fire pipe in large quantities, thereby suppressing the fire.

[0049] Based on this, a storage bin 28 located on the lower side of the float 24 is sleeved on the mounting sleeve 20, and the storage bin 28 is connected to the mounting sleeve 20. A baffle 280 with an annular structure is connected to the float 24 to limit the liquid medium in the mounting sleeve 20 from entering the storage bin 28. Under normal circumstances, the baffle 280 fits tightly against the inner wall of the mounting sleeve 20 to form an effective seal between the mounting sleeve 20 and the storage bin 28. The baffle 280 is also spaced apart from the inner bottom wall of the mounting sleeve 20.

[0050] During use, the high-temperature smoke from the fire drives the liquid medium to expand due to heat until it boils, driving the float 24 and the connecting slide 21 to slide along the mounting sleeve 20 in the direction close to the pipe head 1, so that the limiting guide rod 27 rotates and corresponds to the through hole 272. As the float 24 is driven to continue to slide in the direction close to the pipe head 1, the connecting slide 21 abuts against the connecting frame 26, and then synchronously pushes the connecting frame 26 and a plurality of driving racks 260 to slide synchronously. The sliding of the driving rack 260 drives the meshing driven gear blocks to rotate, driving the driven racks 262 meshing with the driven gear blocks to slide relative to the driving rack 260, that is, the driven rack 262 slides in the direction away from the pipe head 1, and the sliding of the driven rack 262 synchronously drives the connecting plug 10 to slide, so that the connecting plug 10 is separated from the pipe head 1 until the connecting frame 26 abuts against the inner wall of the accommodating cavity.

[0051] At the same time, the sliding of the floating block 24 also drives the baffle 280 to slide, so as to release the seal between the storage bin 28 and the installation sleeve 20. At this time, part of the liquid medium in the installation sleeve 20 will flow into the storage bin 28, causing the liquid level of the liquid medium accumulated in the installation sleeve 20 to move down. At this time, under the action of the water pressure in the fire-fighting pipe, the connecting plug 10, the connecting frame 26, the limiting ring plate 22, the driven gear 261, the driving rack 260, the driven rack 262, the connecting slide rod 21, the floating block 24 and the baffle 280 are driven to slide further away from the pipe head 1 as a whole, until the end of the baffle 280 away from the floating block 24 is against the installation sleeve 20, so that the connecting plug 10 is further separated from the pipe head 1, increasing the distance between the connecting plug 10 and the pipe head 1, avoiding affecting the discharge efficiency of the foam at the pipe head 1, and at the same time, the storage bin 28 and the installation sleeve 20 are sealed again.

[0052] In the process of the connecting plug 10 and the limiting ring plate 22 sliding further away from the pipe head 1 as a whole, the reset spring 23 is forced to be compressed. After the fire is extinguished, the water pressure in the fire-fighting pipeline decreases or weakens, that is, the force applied to the connecting plug 10 and the connecting slide rod 21 as a whole stops or weakens. In the process of resetting the compressed reset spring 23, the limiting ring plate 22, the connecting plug 10, the connecting slide rod 21, the connecting frame 26, the driven gear 261, the driving rack 260, the driven rack 262, the floating block 24 and the baffle 280 are driven to slide and reset as a whole in the direction close to the pipe head 1, so that the liquid medium temporarily stored in the storage bin 28 is re-circulated to the installation sleeve 20.

[0053] With the completion of the reset process, the entire device returns to its initial standby state. At this time, the limit guide rod 27 rotates under the action of the reset spring 23 and is re-displaced with the through hole 272, effectively preventing accidental leakage of the liquid medium. The float block 24 floats back to its initial position under the buoyancy of the liquid medium, and the baffle 280 is also reset to ensure the sealing between the storage bin 28 and the installation sleeve 20. The overall automatic operation of the device greatly improves the reliability and reusability of the device, and the entire emergency response and reset process can be completed without human intervention. The entire device can respond quickly when a fire occurs and automatically return to standby mode after the fire is extinguished, providing efficient and reliable fire protection for hazardous chemical storage tank areas.

[0054] During operation: the first step is to control the connection plug 10 to be limited and inserted into the pipe head 1 through the telescopic end 2, and then connect the pipe head 1 to the fire protection pipeline.

[0055] Step 2: After a fire occurs, the liquid medium in the installation sleeve 20 expands due to heat, driving the connecting slide rod 21 and the installation sleeve 20 to slide relative to each other and shrink, driving the connecting plug 10 to separate from the pipe head 1, thereby releasing the seal on the pipe head 1 and allowing the fire water in the fire pipe to be discharged.

[0056] Step 3: After the fire is contained, the reset spring 23 elastically resets the connecting slide rod 21 and the connecting plug 10 to slide and reset, so that the connecting plug 10 is re-positioned and inserted on the pipe head 1 to seal it.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0058] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
