Description
Technical Field
[0001] The invention relates to a protective suit, in particular to an air-blasting steady-flow heat dissipation protective suit and a use method thereof. Background Art
[0002] In industrial production and life, we often encounter situations where we need to enter high-temperature areas for emergency rescue. For example, if a high-temperature pipeline leaks in a thermal power plant, the nearest valve needs to be closed urgently, and if a high-temperature meter leaks, it needs to be checked and handled nearby, fire rescue, etc. These high-temperature areas cannot be entered directly by personnel, and even if they are wearing clothes made of heat-insulating materials, they can only enter for a short time, making it difficult to handle and carry out effective rescue in time.
[0003] To address this problem, the present application proposes a blast steady flow heat dissipation protective clothing, which utilizes the principle of convective heat absorption by blasting and the heat being carried away by the flowing air to dissipate heat, thereby preventing the human body from being exposed to high temperatures and thus playing a protective role for the human body. Summary of the invention
[0004] In view of the deficiencies in the prior art, the present invention provides air-blasting steady-flow heat dissipation protective clothing and a use method thereof.
[0005] In a first aspect, the present invention provides a blast-steady-flow heat dissipation protective suit, comprising a one-piece protective suit body, wherein the one-piece protective suit body comprises a protective hood, a protective top, protective pants and protective foot covers, wherein the protective hood and the protective top are provided with a placket for wearing and taking off, and a zipper is installed at the placket; the one-piece protective suit body comprises an inner protective layer and an outer protective layer, wherein a cavity is arranged between the inner protective layer and the outer protective layer, wherein a plurality of pull wires connecting the inner protective layer and the outer protective layer are evenly distributed in the cavity, wherein one end of each pull wire is fixedly connected to the inner protective layer, and the other end is fixedly connected to the outer protective layer; a plurality of air outlets communicating with the outside are evenly distributed on the outer protective layer, and a one-way valve is installed in each air outlet to prevent outside air from entering the cavity; an air inlet is arranged on the outer protective layer of the protective top, The air inlet is connected to the air outlet of the air cooler through an air supply hose; transparent observation lenses are installed on the inner protective layer and the outer protective layer opposite to the eyes; a breathing port connected to the cavity is provided on the inner protective layer corresponding to the nose; the inner protective layer is connected to a pressure relief pipe, and the pressure relief pipe passes through the outer protective layer; at least one wind indication hole is provided above the transparent observation lens on the outer protective layer, the wind indication hole is connected to the cavity, a fixing rod is installed in the wind indication hole, and a colored cloth strip is fixed on the fixing rod; a rotating shaft is connected between the transparent observation lens of the inner protective layer and the transparent observation lens of the outer protective layer, an impeller is connected to the rotating shaft through a bearing, an air duct is installed in the cavity, one end of the air duct is fixedly installed at the air inlet on the outer protective layer, and the other end is fixedly installed directly below the impeller and blows air toward the impeller.
[0006] Preferably, the outer protective layers corresponding to the protective hood, protective top, protective pants and protective foot covers are all provided with air outlet holes.
[0007] Preferably, the inner protective layer is made of aramid, polybenzimidazole, or polyphenylene sulfide fiber, and the outer protective layer is made of glass fiber or carbon fiber.
[0008] Preferably, air outlet holes for directly blowing the hands are evenly distributed on the outer protective layer corresponding to the cuffs of the protective jacket.
[0009] Preferably, the inner protective layer and the outer protective layer opposite to the sole of the foot are both rigid panels, the inner protective layer and the outer protective layer opposite to the sole of the foot are connected by a rigid support block, the outer protective layer opposite to the sole of the foot is provided with air holes, and the outer protective layer opposite to the sole of the foot is fixedly connected to a sole support block that does not block the air holes.
[0010] In a second aspect, the present invention provides a method for using a blast steady flow heat dissipation protective clothing, comprising the following steps:
[0011] ① Before entering the high temperature area, start the air cooler first, observe whether the air cooler rotates normally, whether there is obvious vibration or abnormal sound, and then stop the air cooler;
[0012] ② Connect the air outlet of the air cooler to the air inlet on the outer protective layer, start the air cooler again, check whether there is any leakage at the connection part, and then stop the air cooler;
[0013] ③ Unzip the protective clothing, put on the protective clothing, and check whether the eyes are clearly visible;
[0014] ④ Turn on the air cooler and check the expansion and air outlet of the protective suit. If the protective suit is elastic when you pinch it with your hands, put your hands on the air outlet and the air is exhausted strongly. The colored cloth strips cannot be seen through the transparent observation lens. The colored cloth strips are blown straight again in an instant after you grab them and release them. The air inlet at the nose and the person's breathing are normal. Only if all the above are met can it be considered qualified;
[0015] ⑤ Wear heat-insulating gloves and walk into the high-temperature area to carry out emergency rescue operations. If you see colored strips, or the wind speed decreases, or any part of the body slowly becomes hot, you should leave the high-temperature area immediately for inspection;
[0016] ⑥ After leaving the high temperature area, let the air cooler continue to run for 2 minutes to ensure that the protective clothing is completely cooled before stopping the air cooler and putting away the protective clothing.
[0017] The beneficial effects of the present invention are:
[0018] 1. The cold air generated by the air cooler is transported into the cavity and then discharged through the air outlet holes evenly distributed on the outer protective layer. After entering the cavity, the cold air cools down the body of the one-piece protective suit to prevent overheating of the human body. At the same time, the cold air takes out the heat dissipated by the human body and the external heat absorbed by the outer protective layer during the circulation process. In this way, the protective suit and the human body are continuously cooled down to play a protective role.
[0019] 2. The cold air generated by the air cooler is continuously discharged through the air outlet holes evenly distributed on the outer protective layer, forming a cold air isolation barrier on the outside of the outer protective layer that covers the outer protective layer, which effectively blocks the external hot air and achieves heat insulation and heat resistance effects.
[0020] 3. In normal use, the cold air in the cavity will be discharged through the wind holes and blow the colored cloth strips. When the wind flow is strong, the colored cloth strips are blown to nearly horizontal by the strong wind, and the human eye cannot see the colored cloth strips. When the air cooler fails and the wind pressure is reduced or other abnormalities occur, the wind flow intensity is reduced, and the colored cloth strips drop due to their own gravity. The human eye will be able to observe the colored cloth strips. At this time, personnel should immediately leave the high temperature area and check the protective clothing.
[0021] 4. The foot support block can bear the weight and insulate the heat from the ground, while ensuring the normal discharge of cold air from the vents. The rigid support block not only supports the body weight, but also the distance between the inner and outer protective layers ensures the normal output of cold air and plays a role in stabilizing the flow.
[0022] 5. With the help of a fan, this protective clothing can be used for a long time in high temperature areas. It has a good protective effect and ensures personal safety. It does not require additional oxygen and can be widely used in production and life.
[0023] 6. The comprehensive setting of wind holes, colored cloth strips, impellers and air ducts can provide a good early warning of the equipment's operating conditions, ensuring the safety of users. Ensuring the safety of users is the core and key element in the use of protective clothing. If the safety of personnel is not guaranteed in this way, the protective clothing will have no value or significance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0031] Blast steady flow heat dissipation protective clothing, such as Figure 1 , 2 As shown in Figures 3 and 4, the one-piece protective suit includes a protective hood 1, a protective coat 2, protective pants 3 and protective foot covers 4. The protective hood 1 and the protective coat 2 are provided with plackets for wearing and taking off, and a zipper (not marked in the figure) is installed at the placket. When wearing, unzip the zipper to put it on, and after zipping up the zipper, the human body is wrapped.
[0032] The one-piece protective clothing body includes an inner protective layer 5 and an outer protective layer 6, a cavity 10 is arranged between the inner protective layer 5 and the outer protective layer 6, and a plurality of pull wires 11 connecting the inner protective layer 5 and the outer protective layer 6 are evenly distributed in the cavity 10, one end of each pull wire 11 is fixedly connected to the inner protective layer 5, and the other end is fixedly connected to the outer protective layer 6. A plurality of air outlets 7 communicating with the outside are evenly distributed on the outer protective layer 6, and a one-way valve (not marked in the figure) is installed in each air outlet 7 to prevent the outside air from entering the cavity 10. An air inlet 8 is arranged on the outer protective layer 6 of the protective top 2, and the air inlet 8 is connected to the air outlet of the air cooler (not marked in the figure) through an air hose (not marked in the figure). The cold air generated by the air cooler is transported to the cavity 10, and then discharged through the air outlets 7 evenly distributed on the outer protective layer 6. After the cold air enters the cavity 10, it cools down the one-piece protective clothing body on the one hand to prevent the human body from overheating. At the same time, the cold air takes out the heat dissipated by the human body and the external heat absorbed by the outer protective layer 6 during the circulation process, so that the protective clothing and the human body are continuously cooled down, playing a protective role. The cold air generated by the air cooler is continuously discharged through the air outlet holes 7 evenly distributed on the outer protective layer 6, forming a cold air isolation barrier covering the outer protective layer 6 on the outside of the outer protective layer 6, which effectively blocks the external hot air and achieves the effect of heat insulation and heat resistance.
[0033] In this embodiment, the outer protective layers 6 corresponding to the protective head cover 1 , the protective top 2 , the protective pants 3 and the protective foot covers 4 are all provided with air outlet holes 7 .
[0034] The inner protective layer 5 is made of organic high temperature resistant fibers such as aramid, polybenzimidazole, and polyphenylene sulfide fibers, and the outer protective layer 6 is made of inorganic high temperature resistant fibers such as glass fibers and carbon fibers.
[0035] Transparent observation lenses 13 are installed on the inner protective layer 5 and the outer protective layer 6 opposite to the eyes. Transparent observation lenses 13 are provided on the inner protective layer 5 and the outer protective layer 6, which can play a double protection for the eyes.
[0036] The inner protective layer 5 corresponding to the nose is provided with a breathing port 18 connected to the cavity 10, and the cold air in the cavity 10 enters the nasal cavity through the breathing port 18 for human breathing. The inner protective layer 5 is connected to a pressure relief pipe 19, which passes through the outer protective layer 6 and is sealed at the passing position by a sealant. The function of the pressure relief pipe 19 is to discharge the excess air between the human body and the inner protective layer 5 and the gas generated by human breathing. During the process of discharging gas, the pressure relief pipe 19 is isolated from the cavity 10, so the cold air in the cavity 10 will not enter the pressure relief pipe 19. Exhausting the pressure relief pipe 19 can prevent the inner protective layer 5 from expanding and causing a sense of oppression to the human body.
[0037] In order to ensure the flexibility of the hands and not affect the rescue operation, no external structure is set on the hands, but they are directly exposed to the outside. The air outlets 7 that blow directly to the hands are evenly distributed on the outer protective layer 6 corresponding to the cuffs of the protective coat 2, and the cold air blows directly to the hands to cool them down. Compared with other parts, the air outlets 7 on the cuffs are relatively densely arranged and have a larger aperture, which can provide sufficient wind flow for cooling the hands. When using, wearing ordinary heat-insulating gloves can better reduce the radiant heat on the hands.
[0038] Since the high-temperature area is more risky, in order to ensure personal safety, at least one wind hole 14 is provided above the transparent observation lens 13 on the outer protective layer 6. The wind hole 14 is connected to the cavity 10, and a fixing rod 20 is installed in the wind hole 14, and a colored cloth strip 15 is fixed on the fixing rod 20. In normal use, the cold air in the cavity 10 will be discharged through the wind hole 14 and blow the colored cloth strip 15. When the wind flow is strong, the colored cloth strip 15 is blown to nearly horizontal by the strong wind, and the human eye cannot see the colored cloth strip 15. When a cold air machine fails and causes a decrease in wind pressure or other abnormalities, the wind flow intensity decreases, and the colored cloth strip 15 drops due to its own gravity. The human eye will be able to observe the colored cloth strip 15. At this time, personnel should immediately leave the high-temperature area and check the protective clothing.
[0039] To further ensure personal safety, a rotating shaft 17 is connected between the transparent observation lens 13 of the inner protective layer 5 and the transparent observation lens 13 of the outer protective layer 6, and an impeller 16 is connected to the rotating shaft 17 through a bearing. An air duct 9 is installed in the cavity 10, and one end of the air duct 9 is fixedly installed at the air inlet 8 on the outer protective layer 6, and the other end is fixedly installed directly below the impeller 16 and blows air toward the impeller 16. The air duct 9 can directly deliver part of the air from the air cooler to the impeller 16 position and realize the rotation of the impeller 16. During the operation, the operator can directly know the operating status and wind flow intensity of the air cooler by directly observing the rotation of the impeller 16. When the impeller 16 rotates at a low speed or does not rotate, the personnel should immediately leave the high temperature area and check the protective clothing. When installing the impeller 16, it should be installed in a position where it can be seen by the eyes but does not block the line of sight. At the same time, the air duct 9 delivers the wind directly to the impeller 16, which can also serve as an effective supplement to the breathing air source of the breathing port 18, which can ensure that the personnel breathe smoothly and the safety is effectively guaranteed. The comprehensive arrangement of the air holes 14, the colored cloth strips 15, the impeller 16 and the air duct 9 plays a good early warning role in the operation status of the equipment, so that the safety of the users is guaranteed. Ensuring the safety of the users is the core key element in the use process of protective clothing. If the safety of the personnel is not guaranteed in this way, the protective clothing will have no value or significance.
[0040] The inner protective layer 5 and the outer protective layer 6 opposite to the sole of the foot are both rigid plates, and the inner protective layer 5 and the outer protective layer 6 opposite to the sole of the foot are connected by a rigid support block, and the outer protective layer 6 opposite to the sole of the foot is provided with an air outlet 7, and the outer protective layer 6 opposite to the sole of the foot is fixedly connected with a sole support block 12 that does not block the air outlet 7. The sole support block 12 can bear the weight and insulate the heat of the ground, and at the same time ensure the normal discharge of cold air from the air outlet 7. The rigid support block not only supports the body weight, but also maintains the distance between the inner protective layer 5 and the outer protective layer 6, ensures the normal output of cold air, and plays a role in stabilizing the flow.
[0041] The method of using the blast steady flow heat dissipation protective clothing includes the following steps:
[0042] ① Before entering the high temperature area, start the air cooler first, observe whether the air cooler rotates normally, whether there is obvious vibration or abnormal sound, and then stop the air cooler;
[0043] ② Connect the air outlet of the air cooler to the air inlet on the outer protective layer, start the air cooler again, check whether there is any leakage at the connection part, and then stop the air cooler;
[0044] ③ Unzip the protective clothing, put on the protective clothing, and check whether the eyes are clearly visible;
[0045] ④ Turn on the air cooler and check the expansion and air outlet of the protective suit. If the protective suit is elastic when you pinch it with your hands, put your hands on the air outlet and the air is exhausted strongly. The colored cloth strips cannot be seen through the transparent observation lens. The colored cloth strips are blown straight again in an instant after you grab them and release them. The air inlet at the nose and the person's breathing are normal. Only if all the above are met can it be considered qualified;
[0046] ⑤ Wear heat-insulating gloves and walk into the high-temperature area to carry out emergency rescue operations. If you see colored strips, or the wind speed decreases, or any part of the body slowly becomes hot, you should leave the high-temperature area immediately for inspection;
[0047] ⑥ After leaving the high temperature area, let the air cooler continue to run for 2 minutes to ensure that the protective clothing is completely cooled before stopping the air cooler and putting away the protective clothing.
[0048] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention.
