Description

Technical Field

[0001] This invention relates to the field of protective clothing. Background Technology

[0002] In the event of a fire in public places such as schools, hospitals, office buildings, entertainment venues, hotels, residential communities, and homes, it is necessary to have effective emergency protective clothing that enables quick and self-reliant escape or seek rescue opportunities, as well as protective clothing that effectively reduces burns. This clothing has multiple functions, including flame retardancy, mouth and nose breathing, smoke filtration, self-service emergency alarm, temporary oxygen supply, and water spray cooling, and can be adapted to different rescue plans in different situations. This solution is designed with multi-stage, multi-functional emergency fire protective clothing to meet the above requirements. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a fire emergency escape protective suit with multiple protective functions and working stages, which can provide reliable protective functions in each working stage.

[0004] Technical solution: To achieve the above objectives, the fire emergency escape protective suit of the present invention includes a protective suit made of flame-retardant material, a protective hood integrally connected to the upper part of the protective suit, a smoke mask provided at the front of the protective hood, a water bladder a provided at the top of the protective hood, and a water guide pipe on the protective hood with the water inlet end connected to the water bladder a. Several capillary drainage holes on the water guide pipe are distributed on the contour parts of both sides of the smoke mask.

[0005] Furthermore, a manual valve is installed at the inlet end of the water supply pipeline.

[0006] Furthermore, the smoke mask is made of flame-retardant knitted ribbed material.

[0007] Furthermore, the protective suit has a water bladder (b) on the back, which is a pre-filled water chamber. The front of the protective suit has a first protective pocket, which contains a free-flowing hose. The end of the hose is connected to a handheld combined outlet. The protective suit has pipes (a) and pipes (b) arranged inside. The outlet on one side of the water bladder (b) is connected to one end of pipe (a), and the other end of pipe (a) is connected to the inlet end of the hose.

[0008] Furthermore, the protective suit has a b-pipe inside, a second protective pocket at the front, and an aeration pipe horizontally installed at the bottom of the water pre-filling chamber. The horizontal aeration pipe has several aeration holes evenly cut out and is lower than the outlet. The second protective pocket contains a portable compressed air bottle with an air outlet at the top. The outlet of the air outlet is connected to one end of the b-pipe, and the other end of the b-pipe is connected to the aeration pipe.

[0009] Furthermore, the air outlet is equipped with a manual valve; the air outlet is vertically bypassed to an ambient air inlet, and the ambient air inlet is equipped with a one-way valve. The one-way valve prevents the air in the air outlet from going out to the outside through the ambient air inlet. Under the conduction of the one-way valve, the ambient air can be introduced into the air outlet through the ambient air inlet.

[0010] Furthermore, the handheld combination delivery head includes a suction nozzle and a spray nozzle connected to the end of the connecting hose. The suction nozzle is equipped with a manual valve at its tail inlet. The suction port of the suction nozzle has an internal thread on its inner wall, and the spray nozzle has an external thread on its outer wall at its tail inlet. The outer wall of the spray nozzle tail inlet is threadedly engaged with and connected to the inner wall of the suction port. The end of the spray nozzle is the spray outlet.

[0011] Furthermore, with both manual valve a and manual valve b open:

[0012] Compressed air from the compressed air cylinder is forced out through the air outlet. The compressed air from the air outlet is then forced into the water pre-filling chamber of the water bag in the form of bubbles through pipe b and the aeration pipe. The bubbles in the water pre-filling chamber rise to the top, thereby increasing the pressure in the water pre-filling chamber. Water in the lower part of the water pre-filling chamber is continuously forced out through the outlet to pipe a. Then, the water in pipe a is further forced into the hose and sprayed out in the form of water spray from the spray nozzle at the end of the handheld combination outlet head. During the rapid spraying of water spray, when the water level in the water pre-filling chamber drops below the outlet, the water in the water pre-filling chamber can no longer be discharged through the outlet.

[0013] Furthermore, the water level in the pre-filled water tank drops below the outlet, and the spray nozzle on the handheld combined outlet head is removed during the following conditions:

[0014] The air above the water level in the pre-filled water chamber will be continuously forced out from the outlet into pipe a under the action of air pressure. Then, the air in pipe a will be further forced into the hose and discharged from the suction nozzle of the handheld combination outlet head.

[0015] Furthermore, when the compressed air in the portable compressed air cylinder is completely depleted, negative pressure is applied to the suction port of the mouthpiece containing the air inlet by suction. Under the action of negative pressure, the ambient air passes through the one-way valve in the ambient air inlet and reaches the air outlet. Then, the ambient air entering the air outlet passes through pipe b and the aeration pipe and is aerated upwards from the residual water at the bottom of the water pre-filling chamber to the upper part of the water pre-filling chamber in the form of fine bubbles. Finally, the ambient air in the upper part of the water pre-filling chamber, which has been filtered by aeration, is continuously drawn from the outlet into pipe a. Then, the filtered air in pipe a is further drawn into the hose and finally sucked into the mouth of the person through the mouthpiece.

[0016] Beneficial effects: In the first stage of the invention, the water sprayed rapidly from the spray nozzles drenches the whole body and the smoke mask, making the protective clothing completely wet, thereby playing a role in pre-cooling. At the same time, the smoke mask is initially moistened, enhancing the smoke mask's ability to filter smoke.

[0017] In the second stage, the water in the water bladder is continuously and slowly supplied to the smoke mask through the capillary drain pipe under the connection of the water guide pipe, so that the smoke mask can be kept in a moist state and play a regular role in filtering smoke.

[0018] In the third stage, the air that personnel obtain from the nozzles comes entirely from clean air compressed by portable compressed air cylinders, thus avoiding oxygen deficiency and poisoning during a fire.

[0019] In the fourth stage, as the aeration pipes aerate from the residual water at the bottom of the water pre-filling tank to the upper part of the water pre-filling tank in the form of fine bubbles, the smoke particles and soluble toxic gases in the bubbles are absorbed by the residual water at the bottom of the water pre-filling tank 28, thus playing a role in efficiently filtering smoke.

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] As attached Figures 1 to 5 The fire emergency escape protective clothing shown is as follows: Figure 1As shown, the protective suit includes flame-retardant material. The arms of the protective suit are equipped with reflective strips 5. For easy and quick dressing, the suit uses flame-retardant Velcro 61, magnetic buckles, magnetic strips and other automatic closure mechanisms. The ends of the arms are equipped with flame-retardant knitted ribbed drawstrings 16. There are elastic bands 6 on both sides of the front of the protective suit. An automatic alarm call device 4 is installed on the chest of the protective suit. There are locking units 50 on the elastic bands 6. The locking units 50 are equipped with a triggering device that can trigger the automatic alarm call device 4. When the locking unit 50 is in the locked state, the triggering device is triggered, so that the automatic alarm call device 4 will automatically call and sound an alarm.

[0027] The protective suit is integrally connected to a protective cap 4 at the top. A smoke mask 3 is installed at the front of the protective cap 4. The smoke mask 3 is made of flame-retardant knitted rib material and has strong water absorption. In this solution, the top of the protective cap 4 is equipped with a water bladder 1. The protective cap 4 is equipped with a water inlet pipe 2 connected to the water bladder 1. The water inlet of the water inlet pipe 2 is equipped with a manual valve 50. Several capillary drainage holes on the water inlet pipe 2 are distributed on the contour parts of both sides of the smoke mask 3. After the manual valve 50 is opened, the water in the water bladder 1 is continuously and slowly supplied to the smoke mask 3 through the capillary drainage pipe under the connection of the water inlet pipe 2, so that the smoke mask 3 can be kept in a continuously moist state. The personnel breathe smoothly by filtering the smoke through the moist smoke mask 3.

[0028] like Figure 2 and Figure 3 The protective suit has a water bladder 12 on the back, containing a pre-filled water chamber 28. The front of the suit has a first protective pocket 7 and a second protective pocket 8. The first protective pocket 7 contains a free-flowing hose 10, the end of which is connected to a handheld combined outlet head 20. Inside the protective suit are pipes a 11 and b 13. An outlet 29 on one side of the water bladder 12 connects to one end of pipe a 11, and the other end of pipe a 11 connects to the inlet end of the hose 10. Figure 5 The bottom of the water pre-filling chamber 28 is horizontally provided with an aeration pipe 16. The horizontal aeration pipe 16 has several small aeration holes 30 evenly cut out. The aeration pipe 16 is lower than the outlet 29. The second protective bag 8 contains a portable compressed air bottle 15. The upper end of the portable compressed air bottle 15 is an air outlet nozzle 17. The outlet end of the air outlet nozzle 17 is connected to one end of the b pipe 13, and the other end of the b pipe 13 is connected to the aeration pipe 16.

[0029] A manual valve 18 is provided on the air outlet 17; an ambient air inlet 19 is vertically bypassed to the air outlet 17, and a one-way valve is provided inside the ambient air inlet 19. The one-way valve prevents the air in the air outlet 17 from going out to the outside through the ambient air inlet 19. Under the conduction of the one-way valve, the ambient air outside can be introduced into the air outlet 17 through the ambient air inlet 19.

[0030] like Figure 4 As shown, the handheld combination delivery head 20 includes a suction nozzle 22 and a spray nozzle 25 connected to the end of the connecting hose 10. The suction nozzle 22 is equipped with a manual valve 21 at its tail inlet end. The suction port 23 of the suction nozzle 22 has an internal thread on its inner wall. The spray nozzle 25 has an external thread 24 on its outer wall at its tail inlet end. The outer wall of the spray nozzle 25's tail inlet end is threadedly engaged with and connected to the inner wall of the suction port 23. The end of the spray nozzle 25 is a spray port 27. The side wall of the spray nozzle 25 has an assist arm 26.

[0031] Working principle: When a fire breaks out, personnel immediately put on protective clothing and fasten the locking unit 50, which will cause the automatic alarm call device 4 to automatically call and sound an alarm; at the same time, manual valves a18, b21 and c50 are opened.

[0032] This protective suit has the following four working stages:

[0033] Phase 1: Compressed air from compressed air cylinder 15 is forced out through air outlet 17. Due to the one-way valve, the compressed air from air outlet 17 cannot escape to the outside through ambient air inlet 19. Therefore, the compressed air from air outlet 17 is forced into the water pre-filling chamber 28 in water bladder 12 in the form of bubbles through pipe b 13 and aeration pipe 16. The bubbles in the water pre-filling chamber 28 rise to the top, thereby increasing the pressure in the water pre-filling chamber 28. Under pressure, the water in the lower part of the water pre-filling chamber 28 is continuously forced out through outlet 29 to pipe a 11. Then, the water in pipe a 11 is further forced into hose 10 and sprayed out from the spray nozzle 27 at the end of the spray nozzle 25 of the handheld combination outlet head 20 in the form of water spray. At this time, the personnel hold hose 10 and hand The combined outlet head 20 sprays water rapidly from the spray nozzle 27 at the end of the spray nozzle 25, drenching the entire body and smoke mask 3, thus pre-cooling the protective clothing. At the same time, the smoke mask 3 is initially moistened, enhancing its ability to filter smoke. During the rapid spraying of water from the spray nozzle 27, the water in the water pre-filling tank 28 is rapidly consumed, causing the water level to drop rapidly. When the water level in the water pre-filling tank 28 drops below the outlet 29, the water in the water pre-filling tank 28 can no longer be discharged through the outlet 29, and the water spraying process of the spray nozzle 27 ends. Manually close the manual valve 21 to end the water spraying process. The time from the start of water spraying by the spray nozzle 27 to the water level in the water pre-filling tank 28 dropping below the outlet 29 in this stage is controlled within 15 seconds.

[0034] Second stage: If the smoke in the ambient gas at the personnel's location is too dense and there are toxic gases, this stage is immediately skipped and the "third stage" below is executed directly; if there is only a small amount of smoke in the ambient gas at the personnel's location, this stage is executed. In this stage, the personnel breathe smoothly by filtering the smoke through the moistened smoke mask 3. At the same time, the water in the water bag 1 is continuously and slowly supplied to the smoke mask 3 through the capillary drain pipe under the connection of the water pipe 2, so that the smoke mask 3 can be kept moist, thereby enabling the personnel to evacuate quickly.

[0035] Third stage: When personnel encounter excessively dense smoke and toxic gases in the ambient air; immediately rotate the spray nozzle 25 on the handheld combination outlet head 20 to remove the rotating spray nozzle 25 from the suction port 23, exposing the suction port 23; at this time, the personnel hold the hose 10 and the suction nozzle 22, and put the suction nozzle 22 into their mouth; at this time, reopen the manual valve 21; since the water level in the water pre-filling chamber 28 has dropped below the outlet 29 at the end of the "first stage", the air above the water level in the water pre-filling chamber 28 will be affected by air pressure. The air is continuously pumped from outlet 29 into pipe a 11. Then, the air in pipe a 11 is further pumped into hose 10 and then pumped from the nozzle 22 of handheld assembly outlet 20 into the mouth of personnel for direct breathing. At this time, the air obtained by personnel from nozzle 22 is all clean air pumped from portable compressed air cylinder 15, thereby avoiding oxygen deficiency and poisoning in the fire. This stage can last for at least 15 minutes until the compressed air in compressed air cylinder 15 is completely exhausted. During this stage, personnel need to leave the high-density smoke area as soon as possible.

[0036] Fourth stage: When the compressed air in the portable compressed air cylinder 15 in the "third stage" is completely depleted, the pressure released by the portable compressed air cylinder 15 disappears, and the suction nozzle 22 in the inlet will not actively discharge clean air; although the water level in the water pre-filling chamber 28 has dropped below the outlet 29, there is still enough residual water at the bottom of the water pre-filling chamber 28 to submerge the horizontal aeration pipe 16; at this time, the personnel apply negative pressure to the suction port 23 of the suction nozzle 22 in the inlet by suction, and finally the negative pressure is transmitted to the ambient air inlet 19. At this time, the external ambient air, under the action of negative pressure, passes through the one-way valve in the ambient air inlet 19 and reaches the air outlet 17. Then, the ambient air entering the air outlet 17 passes through the b pipe 13 and the aeration pipe 16 in a fine mist. Bubbles are aerated from the residual water at the bottom of the water pre-filling chamber 28 and then aerated from the aeration pipe 16 to the top of the water pre-filling chamber 28 in the form of fine bubbles. During this process, smoke particles and soluble toxic gases in the bubbles are absorbed by the residual water at the bottom of the water pre-filling chamber 28, thus achieving efficient filtration of smoke. Finally, the ambient air in the upper part of the water pre-filling chamber 28, which has been filtered by aeration, is continuously drawn from the outlet 29 into pipe a 11. Subsequently, the filtered air in pipe a 11 is further drawn into the hose 10 and finally into the mouth of personnel through the mouthpiece 22 for breathing. Although smoke particles can be efficiently absorbed through aeration at this stage, the threat of carbon monoxide cannot be avoided. Therefore, it is necessary to escape from the fire source as soon as possible.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
