Description

Technical Field

[0001] This utility model relates to the field of protective clothing technology, specifically to a protective clothing with a heat insulation system. Background Technology

[0002] Protective clothing includes fire-fighting protective clothing, industrial protective clothing, medical protective clothing, military protective clothing, and protective clothing for special groups. In high-temperature working environments, such as fire rescue sites, personnel involved in rescue work need to use fire-fighting protective clothing and other heat-insulating protective clothing to prevent damage to their bodies from external high temperatures.

[0003] During fire rescue operations, personnel engage in high-intensity activities such as climbing, running, and carrying heavy objects, which exacerbate the generation of body heat. If the large amount of heat generated cannot be dissipated in time, the body temperature can easily rise to a dangerous level, leading to heatstroke, fainting, and other conditions. Traditional high-temperature protective clothing consists of a flame-retardant fabric layer, a heat-insulating fabric layer, and a cushioning fabric layer, arranged sequentially from the outside to the inside. The fabric is the material used to make the clothing. While the heat-insulating fabric layer can prevent the transfer of high external temperatures to the body and cause burns, it is not conducive to the timely dissipation of heat. When workers feel hot, they must rest or stop high-intensity activities, which reduces rescue efficiency.

[0004] Therefore, how to prevent external high temperatures from being transmitted to the human body while also enabling the body to dissipate heat in a timely manner is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a protective clothing with a heat insulation system that prevents external high temperatures from being transmitted to the human body and also allows the human body to dissipate heat in a timely manner.

[0006] The technical solution adopted in this utility model is: a protective suit with a heat insulation system, comprising:

[0007] Protective suit body and thermal insulation system;

[0008] The protective suit body includes a flame-retardant fabric layer, a heat-insulating fabric layer, and a cushioning fabric layer arranged sequentially from the outside to the inside.

[0009] The heat insulation system includes cooling water pipes, a water storage bag, a heat exchange plate, a delivery pump, a thermoelectric cooler, and a cooling fan. The cooling water pipes and the water storage bag are distributed between the buffer fabric layer and the heat insulation fabric layer. The outlet of the water storage bag is connected to the inlet of the delivery pump, the outlet of the delivery pump is connected to the inlet of the cooling water pipe, and the outlet of the cooling water pipe is connected to the inlet of the water storage bag. The heat insulation fabric layer is provided with a first mounting through hole, and the flame-retardant fabric layer is provided with a second mounting through hole. The thermoelectric cooler is fixedly installed in the first mounting through hole, with the heat-absorbing end of the thermoelectric cooler contacting the outer surface of the heat exchange plate and the inner surface of the heat exchange plate contacting the water storage bag. The cooling fan is fixedly installed in the second mounting through hole, with the heat-dissipating end of the thermoelectric cooler aligned with the cooling fan.

[0010] Furthermore, the thermal insulation system also includes a control panel and a temperature sensor. The control panel is electrically connected to the temperature sensor, a thermoelectric cooler, a delivery pump, and a cooling fan. The temperature sensor is installed on the cushioning fabric layer.

[0011] Furthermore, the protective suit body is provided with a pocket, the control panel is located in the pocket, and a power bank is also provided in the pocket, which supplies power to the control panel.

[0012] Furthermore, the top of the water storage bag is connected to a water injection pipe, and the inlet of the water injection pipe is provided with a first rubber stopper. The bottom of the water storage bag is connected to a drain pipe, and the inlet of the drain pipe is provided with a second rubber stopper.

[0013] Furthermore, the cushioning fabric layer is provided with a first storage opening and a second storage opening, the water injection pipe is located at the first storage opening, and the drain pipe is located at the second storage opening.

[0014] Compared with the prior art, the beneficial effects or advantages of the present invention are as follows:

[0015] Cooling water pipes and water storage bags are installed between the cushioning fabric layer and the heat insulation fabric layer. The large amount of heat generated by the human body due to high-intensity activities is absorbed by the water in the cooling water pipes and water storage bags. Driven by a delivery pump, the water in the cooling water pipes flows to the water storage bags, where it exchanges heat with the heat exchange fins. The water in the water storage bags then flows back to the cooling water pipes for circulation. The semiconductor cooling chip absorbs the heat from the heat exchange fins and transfers the heat to the cooling fan, which finally discharges the heat to the outside of the protective suit. This invention not only prevents high external temperatures from being transferred to the human body but also allows the body to dissipate heat in a timely manner, effectively preventing fire rescue personnel from having to suspend rescue work due to excessive body temperature, and effectively improving rescue efficiency.

[0021] This utility model embodiment provides a protective suit with a heat insulation system. The overall technical concept is as follows:

[0022] When working in high-temperature environments, such as participating in fire rescue, staff wear protective clothing with a heat insulation system as described in this utility model. The protective clothing consists of a flame-retardant fabric layer, a heat-insulating fabric layer, and a cushioning fabric layer arranged sequentially from the outside to the inside. The flame-retardant fabric layer makes the protective clothing less flammable, the heat-insulating fabric layer prevents the high temperature from the outside from being transferred to the body and causing burns, and the cushioning fabric layer provides cushioning protection for the body. Before engaging in high-intensity activities, staff start the delivery pump, semiconductor cooling chip, and cooling fan. The large amount of heat generated by the body is absorbed by the cooling water pipes and water storage bag through the cushioning fabric layer. The heat flows to the water storage bag with the water in the cooling water pipes, where it exchanges heat with the heat exchanger. The semiconductor cooling chip absorbs the heat from the heat exchanger and then transfers the heat to the cooling fan. The cooling fan dissipates the heat to the outside of the protective clothing, preventing the continuous accumulation of body heat inside the protective clothing, which could lead to heatstroke, fainting, or other conditions. Because the body dissipates heat in a timely manner, personnel can carry out rescue work for a longer period of time.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] See Figures 1 to 3 The preferred embodiment of this utility model.

[0025] A protective suit with a thermal insulation system includes:

[0026] Protective suit body 1 and heat insulation system 2;

[0027] The protective suit body 1 includes a flame-retardant fabric layer 11, a heat-insulating fabric layer 12, and a cushioning fabric layer 13 arranged sequentially from the outside to the inside.

[0028] The heat insulation system 2 includes a cooling water pipe 21, a water storage bag 22, a heat exchange plate 23, a delivery pump 24, a semiconductor refrigeration chip 25, and a cooling fan 26. The cooling water pipe 21 and the water storage bag 22 are distributed between the buffer fabric layer 13 and the heat insulation fabric layer 12. The outlet of the water storage bag 22 is connected to the inlet of the delivery pump 24, the outlet of the delivery pump 24 is connected to the inlet of the cooling water pipe 21, and the outlet of the cooling water pipe 21 is connected to the inlet of the water storage bag 22. The heat insulation fabric layer 12 is provided with a first mounting through hole, and the flame-retardant fabric layer 11 is provided with a second mounting through hole. The semiconductor refrigeration chip 25 is fixedly installed in the first mounting through hole, the heat-absorbing end of the semiconductor refrigeration chip 25 is in contact with the outer surface of the heat exchange plate 23, and the inner surface of the heat exchange plate 23 is in contact with the water storage bag 22. The cooling fan 26 is fixedly installed in the second mounting through hole, and the heat-dissipating end of the semiconductor refrigeration chip 25 is aligned with the cooling fan 26.

[0029] The beneficial effects or advantages of this utility model are as follows: A cooling water pipe 21 and a water storage bag 22 are installed between the cushioning fabric layer 13 and the heat insulation fabric layer 12. The large amount of heat generated by the human body due to high-intensity activities is absorbed by the water in the cooling water pipe 21 and the water storage bag 22. Driven by the delivery pump 24, the water in the cooling water pipe 21 flows to the water storage bag 22, where it exchanges heat with the heat exchange plate 23. The water in the water storage bag 22 then flows back to the cooling water pipe 21 for circulation. The semiconductor cooling plate 25 absorbs the heat from the heat exchange plate 23 and transfers the heat to the cooling fan 26. Finally, the cooling fan 26 discharges the heat to the outside of the protective clothing body 1. This utility model not only prevents the external high temperature from being transferred to the human body, but also allows the human body to dissipate heat in time, effectively preventing fire rescue personnel from suspending rescue work due to excessive body temperature, and effectively improving rescue efficiency.

[0030] In this embodiment, cooling water pipes 21 are distributed on the back and waist of the protective suit body 1, and the cushioning fabric layer 13 has cavities for installing the cooling water pipes 21 and water storage bags 22. The cooling water pipes 21 absorb heat from their location and then flow with the water to the water storage bags for heat exchange. Both the cooling water pipes 21 and the water storage bags 22 can absorb a large amount of heat generated by the human body. The warmer water in the cooling water pipes flows back to the water storage bags 22, where it exchanges heat with the heat exchange fins 23. The cooler water in the water storage bags then flows back to the cooling water pipes 21. The heat exchange fins 23 are located at the waist of the protective suit body 1 and are made of copper, a material with excellent thermal conductivity. The thermoelectric cooler 25 is a common TEC1-12706 model thermoelectric cooler 25. The thermoelectric cooler 25 operates based on the Peltier effect. A cooling fan 26 exhausts the heat dissipation end of the thermoelectric cooler 25 to the outside, contributing to the stable operation of the thermoelectric cooler 25.

[0031] The flame-retardant fabric layer 11 is made of fiberglass cloth, and the outer surface of the fiberglass cloth is coated with a high-temperature resistant adhesive layer. The heat-insulating fabric layer 12 is made of aluminum silicate fiber heat-insulating cloth. The cushioning fabric layer 13 is made of thermally conductive silicone, and a thin cotton cloth is placed on the inner surface of the thermally conductive silicone to improve the comfort of human contact. The flame-retardant fabric layer 11, the heat-insulating fabric layer 12, and the cushioning fabric layer 13 are tightly attached and sewn together for secure connection.

[0032] Furthermore, the thermal insulation system 2 also includes a control panel and a temperature sensor 27. The control panel is electrically connected to the temperature sensor 27, the thermoelectric cooler 25, the delivery pump 24, and the cooling fan 26. The temperature sensor 27 is installed on the cushioning fabric layer 13.

[0033] The beneficial effects of this technical solution are as follows: The control panel has operation buttons, allowing operators to start or stop the thermoelectric cooler 25, the delivery pump 24, and the cooling fan 26 via the control panel. The temperature sensor 27 is used to detect the temperature of the cushioning fabric layer 13. Heat generated by the human body is transferred to the cushioning fabric layer 13. When the detected temperature exceeds a preset temperature threshold (e.g., 38℃), the control panel automatically activates the thermoelectric cooler 25, the delivery pump 24, and the cooling fan 26 to achieve automatic heat dissipation. The control panel can be configured with a microcontroller.

[0034] Furthermore, the protective suit body 1 is provided with a pocket (not shown), the control panel is located in the pocket, and the pocket also contains a power bank (not shown), which supplies power to the control panel.

[0035] The advantages of this technical solution are: it makes it easier for staff to operate the control panel and facilitates the replacement of the power bank.

[0036] Furthermore, the top of the water storage bag 22 is connected to a water injection pipe 28, and the opening of the water injection pipe 28 is provided with a first rubber stopper 281. The bottom of the water storage bag 22 is connected to a drain pipe 29, and the opening of the drain pipe 29 is provided with a second rubber stopper 291.

[0037] The beneficial effects of this technical solution are as follows: opening the first rubber stopper 281 allows water to be added to the cooling water pipe 21, and opening the second rubber stopper 291 allows water to be drained from the cooling water pipe 21, facilitating water replacement. The rubber stoppers serve to seal the pipes.

[0038] Furthermore, the cushioning fabric layer 13 is provided with a first storage port 131 and a second storage port 132, the water injection pipe 28 is located in the first storage port 131, and the drain pipe 29 is located in the second storage port 132.

[0039] The beneficial effects of this technical solution are as follows: Normally, the water inlet pipe 28 and the drain pipe 29 are hidden between the cushioning fabric layer 13 and the heat insulation fabric layer 12. When needed, the staff can take out the water inlet pipe 28 from the first storage port 131 to perform water injection and take out the drain pipe 29 from the second storage port 132 to perform drainage. The first storage port 131 and the second storage port 132 are covered with a cloth (not shown), and the cloth is connected to the cushioning fabric layer 13 by Velcro. Velcro is a product of existing technology, which facilitates the removal and installation of the cloth.

[0040] The protective suit with a heat insulation system of this utility model not only prevents the external high temperature from being transmitted to the human body, but also allows the heat generated by the human body to be discharged to the outside of the protective suit body 1 through the buffer fabric layer 13, cooling water pipe 21, water storage bag 22, heat exchange plate 23, semiconductor cooling plate 25, and cooling fan 26 in sequence. This effectively avoids the personnel from having excessive body temperature due to high-intensity activities during rescue work and improves rescue efficiency.
