Description

Technical Field

[0001] This invention belongs to the field of fire emergency rescue equipment technology, specifically an intelligent wet rescue suit that integrates biological sign monitoring, environmental perception and active temperature control. Background Technology

[0002] The mainstream rescue clothing for fire scenes is usually fire-fighting protective clothing, which is suitable for open flame or high-temperature radiation environments such as building fires, chemical explosions, and forest fires. Its material is usually aramid or flame-retardant cotton on the outer layer to reflect radiant heat, covered with PTFE waterproof and breathable membrane in the middle layer, and flame-retardant fiber heat insulation in the inner layer.

[0003] The existing technical document, CN114711483A, discloses a safety protective fire-fighting suit designed to address the issues of heat stress and fall damage in fire-fighting clothing. The suit incorporates flame-retardant, elastic, and stretchable deformable tubing embedded between its comfort and insulation layers. This tubing provides both cooling liquid flow and fall-proof inflation with intelligent control. The principle behind this is as follows: During firefighting and rescue operations, when the temperature of the air layer beneath the suit exceeds the body's comfort temperature, the tubing allows for the flow of cooling water, enabling the suit to sense heat and intelligently regulate the temperature of the air layer beneath, ensuring a constant and comfortable microenvironmental temperature. In the event of an accidental fall, the soft, elastic, and stretchable tubing acts as a safety airbag, absorbing and buffering external forces to protect firefighters from fall injuries. This safety fire-fighting protective suit avoids the risks of falls and fatalities, as well as heat stress, that can occur during rescue operations, ensuring the safety of rescue personnel. Furthermore, the stretchable tubing provides dual protection against heat stress and fall damage, and the overall cost is relatively low. Although the aforementioned cooling system cools the rescuers' bodies through pipes, its intelligent control effect is limited. When rescuers need to evacuate the current environment due to excessively high perceived temperature, it indicates that the active cooling function of the rescue suit has failed. During this evacuation process, the rescuers will continue to be exposed to the high-temperature environment, which may lead to irreversible heat damage, such as heatstroke and multiple organ dysfunction, seriously threatening their health and safety and hindering the continued progress of the rescue mission and the preservation of personnel. Summary of the Invention

[0004] To address the limited effectiveness of intelligent control in traditional rescue suits as mentioned in the background, this invention provides an intelligent wet rescue suit that integrates biosign monitoring, environmental perception, and active temperature control.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent wet rescue suit integrating biometric monitoring, environmental perception, and active temperature control, comprising an upper garment with sleeves on both sides, trousers below the upper garment, and a protective hood on the top of the upper garment; further comprising: a fabric and sensing components forming the upper garment and trousers; a circulation system component fixedly connected to the upper garment and trousers; an intelligent storage module containing the upper garment and trousers; and a head cooling component located on the protective hood. The head cooling component includes a trapezoidal block that is elastically connected to the inner cavity of the protective cap. The outer wall of the trapezoidal block is slidably abutted against a double-groove plate. The side wall of the double-groove plate is provided with an inclined groove, and the bottom of the double-groove plate is provided with a snap-fit ​​groove.

[0006] Preferably, the fabric and sensing components include a close-fitting sensing layer disposed on the inside of the sleeve, the close-fitting sensing layer being arranged in a hexagonal honeycomb structure, an intermediate sensing layer being fixedly connected to the outside of the close-fitting sensing layer, an outer sensing layer being fixedly connected to the outside of the intermediate sensing layer, and the three-layer sensing network being connected to the main control system.

[0007] Preferably, a sweat-absorbing layer is fixed to the outside of the outer sensing layer, a waterproof and breathable membrane is fixed to the outside of the sweat-absorbing layer, and flame-retardant cotton is fixed to the outside of the waterproof and breathable membrane.

[0008] Preferably, the circulation system component is entirely installed inside the sweat-absorbing layer. The circulation system component includes an upper limb tube located inside the upper garment and a lower limb tube fixedly connected inside the lower pants. Both the upper limb tube and the lower limb tube are externally connected to a heat sink through a magnetic tube interface, and the heat sink is located on the inside of the hem of the upper garment. A neck tube and an armpit tube are fixedly connected to the neck and armpit positions of the upper garment, respectively, and the two are interconnected.

[0009] Preferably, the intelligent storage module includes a cold-rolled steel cabinet, with PTC ceramic heating elements fixed to both sides of the inner cavity of the cold-rolled steel cabinet, dehumidifying fans installed on both sides of the top of the garment, and a controller installed on the outer wall of the cold-rolled steel cabinet, the controller being electrically connected to the PTC ceramic heating elements and the dehumidifying fans.

[0010] Preferably, the head cooling component further includes a double-layer water guide pipe fixed to the upper side of the protective cap. The inner cavity of the double-layer water guide pipe is divided into upper and lower water channels by a partition, and several spray heads and water spray heads are fixedly connected to the two water channels respectively. The multiple spray heads are arranged equidistantly around the circumference on the upper side of the double-layer water guide pipe.

[0011] Preferably, a transparent baffle is fixed to the side wall of the protective cap, and multiple water spray heads are arranged equidistantly above the transparent baffle. The spacing density of the spray heads is greater than that of the water spray heads. Herringbone grooves are formed on the outer wall of the protective cap, and an inner skeleton is installed in the top inner cavity of the protective cap.

[0012] Preferably, the lower water channel of the double-layer water pipe is symmetrically and fixedly connected to a pair of composite rubber water bags through a pair of conduits. The conduits are fixedly inserted through the protective cap, and the composite rubber water bags are located at the lower hem of the protective cap's curtain.

[0013] Preferably, the bottom of the double-layer water guide pipe is fixedly connected to an arc-shaped sleeve, the inner cavity of the arc-shaped sleeve is slidably connected to a telescopic rod, the end of the telescopic rod is rotatably connected to a cloth brush through a rotating shaft, the side wall of the trapezoidal block is fixedly connected to a rack, and the top of the cloth brush is fixedly connected to a gear, the gear and the rack meshing with each other.

[0014] Preferably, the top of the double-groove plate is elastically connected to the telescopic rod, and the bottom of the double-groove plate is engaged with the gear. The inner cavity of the protective cap is fixedly connected to a limiting plate, and the limiting plate is movably connected to the bottom of the rotating shaft through a sliding groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting up a combination of structures such as neck tube, armpit tube and close-fitting sensing layer, this invention facilitates the activation of emergency cycle in high temperature emergency situations. The intermediate sensing layer monitors the vital signs data of rescuers in real time. Once the data exceeds the preset range, a graded alarm mechanism is triggered to warn the rescuers and the command personnel outside the fire scene. When the temperature at the fire scene is too high and the heart rate and body temperature of the rescuers rise abnormally, the emergency cycle is activated. The neck tube and armpit tube quickly cool down and rapidly improve the heat exchange efficiency with the rescuers, thereby providing time for their evacuation and avoiding irreversible damage to the rescuers caused by high temperature. This is conducive to the continuous development of rescue missions and the preservation of personnel.

[0016] (2) By setting up upper limb tubes, lower limb tubes, intermediate sensing layer and outer sensing layer, the present invention facilitates intelligent control of the temperature inside the rescue suit. The main circulation is carried out by the combination of upper limb tubes and lower limb tubes with dense and sparse branch pipes. The internal coolant circulates and exchanges heat with the body temperature of the rescuers to continuously cool down, ensuring that the body temperature of the rescuers is relatively constant and ensuring that the rescuers can carry out rescue missions.

[0017] (3) This invention, through the combination of double-layer water pipes, herringbone grooves and composite rubber water bags, ensures the cooling of the rescuers' heads and the clarity of their vision. The double-layer water pipes can spray water mist upwards and water jets downwards, adapting to cooling different areas of the protective helmet. The water mist sprayed from the spray head gathers at the top of the protective helmet for continuous cooling. Some of the water mist flows down in streams through the herringbone grooves, preventing sewage mixed with smoke and dust from flowing towards the transparent baffle and obstructing the view. The water spray head on the lower side can automatically adjust the water jet washing cycle according to the amount of smoke and dust at the fire scene. In special cases where there is a lot of smoke and dust, the composite rubber water bag can be manually squeezed to increase the pressure, enhance the impact of the water jet, quickly clean the surface of the transparent baffle, and flexibly adjust the water volume to avoid smoke and dust residue obstructing the view.

[0018] (4) By setting up trapezoidal blocks, double groove plates and cloth brushes, the present invention allows rescuers to squeeze the water bag while the water pressure pushes the telescopic rod to wipe the inner surface of the transparent baffle, which can remove the water mist inside the transparent baffle. Combined with the external water spray head to clean the transparent baffle, it achieves the effect of double cleaning inside and outside, ensuring clear vision. When the cloth brush is reset, the trapezoidal block is squeezed by the inclined groove on the double groove plate, which can push the double groove plate upward to compress the spring and release the limit on the gear. Therefore, the gear can mesh with the rack behind, causing the cloth brush to rotate and switch to a new side facing the transparent baffle. This achieves the purpose of the cloth brush rotating a certain distance with each brush stroke, making full use of the brush surface and extending the service life of the cloth brush.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 15 As shown, this invention provides an intelligent wet rescue suit integrating biometric monitoring, environmental sensing, and active temperature control. It includes an upper garment 1 with sleeves 2 on both sides, trousers 4 below the upper garment 1, and a protective hood 3 on the top of the upper garment 1. It also includes: a fabric and sensing component 5, which together form the upper garment 1 and trousers 4; a circulation system component 6, which is fixedly connected to the upper garment 1 and trousers 4; an intelligent storage module 7, which houses the upper garment 1 and trousers 4; and a head cooling component 8, located on the protective hood 3. The head cooling component 8 includes a trapezoidal block 8014 that is elastically connected to the inner cavity of the protective cap 3. The outer wall of the trapezoidal block 8014 slides against a double groove plate 8015. The side wall of the double groove plate 8015 is provided with an inclined groove, and the bottom of the double groove plate 8015 is provided with a snap-fit ​​groove.

[0023] The above solution employs a flexible biosensor array and an environmental sensing matrix, forming a fabric and sensing component 5. This, along with the coolant from the circulation system component 6, is distributed within the rescue suit, creating an intelligent wet rescue suit. An intelligent storage module 7 provides a suitable environment for storing the suit. Furthermore, the fabric and sensing component 5 provide real-time feedback of biological and environmental information, enabling the circulation system component 6 and the head cooling component 8 to work effectively together. This achieves deep integration of the flexible electronic system and protective equipment. A dual-dimensional dynamic temperature control strategy, considering both vital signs and environmental factors, is implemented, along with a tiered alarm system from an intelligent early warning terminal. This ensures continuous operational protection for rescue personnel in harsh environments and provides early warning and evacuation time in emergency situations.

[0024] like Figure 4 and Figure 5 As shown, the fabric and sensing component 5 includes a close-fitting sensing layer 501 disposed on the inside of the sleeve 2. The close-fitting sensing layer 501 is arranged in a hexagonal honeycomb structure. An intermediate sensing layer 502 is fixed to the outside of the close-fitting sensing layer 501, and an outer sensing layer 503 is fixed to the outside of the intermediate sensing layer 502. The three sensing networks are connected to the main control system. A sweat-absorbing layer 504 is fixed to the outside of the outer sensing layer 503, a waterproof and breathable membrane 505 is fixed to the outside of the sweat-absorbing layer 504, and flame-retardant cotton 506 is fixed to the outside of the waterproof and breathable membrane 505.

[0025] The above-mentioned scheme employs an embedded flexible biosensor in the composite sensing system, primarily utilizing a graphene and PVDF piezoelectric film composite structure integrated into the lining of the rescue suit. Multi-parameter synchronous acquisition involves real-time measurement of rescue personnel's body temperature, heart rate variability, muscle oxygen saturation, and surface micro-tremors to accurately assess their health status. The environmental sensing unit utilizes a distributed fiber optic temperature sensor, coupled with a miniature gas sensor array, in conjunction with the flexible biosensor in the rescue suit lining. This forms a three-layer sensing network within the garment: a body-hugging sensing layer 501, a middle sensing layer 502, and an outer sensing layer 503, responsible for bioelectrodes, fiber optic temperature measurement, and gas detection, respectively. Furthermore, the hexagonal honeycomb structure of the body-hugging sensing layer 501 balances signal quality with wearing comfort.

[0026] like Figures 5 to 8As shown, the circulation system component 6 is entirely installed inside the sweat-absorbing layer 504. The circulation system component 6 includes an upper limb tube 601 located inside the upper garment 1 and a lower limb tube 602 fixedly connected inside the lower pants 4. Both the upper limb tube 601 and the lower limb tube 602 are externally connected to a heat sink through a magnetic tube interface, and the heat sink is located on the inside of the hem of the upper garment 1. A neck tube 603 and an armpit tube 604 are fixedly connected to the neck and armpit positions of the upper garment 1, respectively, and the two are interconnected.

[0027] The above-mentioned solution employs a dual-cycle liquid cooling architecture of main and emergency circulation. This architecture differentiates cooling for the upper limb tubes 601 and lower limb tubes 602 in the torso, as well as the neck tubes 603 and axillary tubes 604 in the neck and armpits, based on body temperature detected by a composite sensor system. This allows for adaptive cooling of rescue personnel in extreme fire conditions, prioritizing those with the most urgent needs, thus enhancing temperature control. A paraffin and expanded graphite composite material serves as a phase change material energy storage layer, providing an emergency cooling source. When the ambient temperature exceeds 300 degrees Celsius, the emergency circulation system activates. The high-temperature coolant in the neck tubes 603 and axillary tubes 604 flows through metal channels embedded with PCM / EG modules, transferring heat to the composite material through the channel walls. The expanded graphite forms a three-dimensional network, rapidly conducting heat from the channel walls to the paraffin particle interface, increasing heat transfer speed by 50 times compared to pure paraffin. Paraffin wax melts at a set phase transition temperature, absorbing heat from the coolant and causing the coolant temperature to drop rapidly. This allows for heat exchange with the rescuers' body temperature, preventing a sudden rise in their body temperature. Before the paraffin wax completely melts, the coolant outlet temperature remains stable around the phase transition temperature, providing a period of temperature stability so that rescuers can quickly evacuate from excessively high-temperature environments. In edge computing systems, abnormal vital signs detection is based on time-series data analysis using LSTM networks. Combined with multi-source data fusion algorithms, DS evidence theory is used to achieve joint early warning of rescue personnel's vital signs and the environment. Furthermore, a hierarchical alarm mechanism is used to ensure timely information synchronization and avoid single alarm failures. First, local audible and visual alarms are used, then the data is transmitted to a short-range Mesh network, and finally, it is transmitted remotely via 4G or 5G to achieve real-time information synchronization.

[0028] like Figure 3 As shown, the intelligent storage module 7 includes a cold-rolled steel cabinet 701, with PTC ceramic heating elements 703 fixedly connected to both sides of the inner cavity of the cold-rolled steel cabinet 701; dehumidifying fans 704 are installed on both sides of the top of the garment 1; a controller 702 is installed on the outer wall of the cold-rolled steel cabinet 701, and the controller 702 is electrically connected to the PTC ceramic heating elements 703 and the dehumidifying fans 704.

[0029] The above solution involves storing the rescue suit in a cold-rolled steel cabinet 701 when not in use to shield it from magnetic field interference. Furthermore, the PTC ceramic heating element 703 and the dehumidifying fan 704 are controlled by a controller 702 to maintain a constant temperature and humidity range within the cold-rolled steel cabinet 701, thereby ensuring the continued effectiveness of the rescue suit and improving its durability.

[0030] like Figures 9 to 11 As shown, the head cooling component 8 also includes a double-layer water pipe 801 fixed to the upper side of the protective cap 3. The inner cavity of the double-layer water pipe 801 is divided into upper and lower water channels by a partition 809, and several spray heads 802 and water spray heads 804 are fixedly connected to the two water channels respectively. The multiple spray heads 802 are arranged equidistantly around the circumference on the upper side of the double-layer water pipe 801. A transparent baffle 805 is fixedly connected to the side wall of the protective cap 3. The multiple water spray heads 804 are arranged equidistantly above the transparent baffle 805. The spacing density of the spray heads 802 is greater than that of the water spray heads 804. A herringbone groove 803 is opened on the outer wall of the protective cap 3. An inner frame 806 is installed in the top inner cavity of the protective cap 3. The lower water channel of the double-layer water pipe 801 is symmetrically connected to a pair of composite rubber water bags 808 through a pair of conduits 807. The conduits 807 are fixedly inserted through the protective cap 3, and the composite rubber water bags 808 are located at the lower hem of the cap curtain of the protective cap 3.

[0031] like Figures 12 to 15 As shown, the bottom of the double-layer water pipe 801 is fixedly connected to an arc-shaped sleeve 8012. The inner cavity of the arc-shaped sleeve 8012 is slidably connected to a telescopic rod 8013. The end of the telescopic rod 8013 is rotatably connected to a cloth brush 8010 via a rotating shaft. The side wall of the trapezoidal block 8014 is fixedly connected to a rack 8017. The top of the cloth brush 8010 is fixedly connected to a gear 8016, and the gear 8016 and the rack 8017 mesh with each other. The top of the double-groove plate 8015 is elastically connected to the telescopic rod 8013, and the bottom of the double-groove plate 8015 is engaged with the gear 8016. The inner cavity of the protective cap 3 is fixedly connected to a limiting plate 8011, and the limiting plate 8011 is movably connected to the bottom of the rotating shaft via a sliding groove.

[0032] The above solution is adopted: the composite rubber water bag 808 is made of platinum vulcanized silicone rubber, which has a continuous operating temperature range of -50℃ to 250℃ and can also withstand short-term high-temperature flame impact. After heat aging, the tensile strength retention rate is greater than 85%, which is better than the 60% of ordinary silicone. The double-layer water pipe 801 is connected to the external rescue water tank to provide water.

[0033] Working principle and usage process of this invention: After rescuers don their rescue suits and enter the fire scene, the temperature of the clothing gradually rises. At this point, the main control system activates the main circulation system, circulating the coolant inside the upper limb tubes 601 and lower limb tubes 602 to exchange heat with the rescuers' body temperature for continuous cooling. Simultaneously, biosensors in the body-contact sensing layer 501 monitor and report the rescuers' vital signs in real time, while the intermediate sensing layer 502 and outer sensing layer 503 perform fiber optic temperature measurement and gas detection on the outside of the clothing. During normal use, the flow rate of the upper limb tubes 601 and lower limb tubes 602 is adjusted in real time according to changes in the ambient temperature of the fire scene to ensure a relatively constant body temperature for the rescuers. If data exceeds the preset range, a tiered alarm mechanism is triggered, alerting both the rescuers and command personnel outside the fire scene. Typically, the high temperature at the fire scene causes an abnormal increase in the rescuers' heart rate and body temperature, thus requiring the activation of the emergency circulation system. The neck tube 603 and axillary tube 604 are used to quickly cool down the body and rapidly improve the efficiency of heat exchange with rescuers, thereby providing them with time to evacuate and avoiding irreversible damage to rescuers caused by high temperature. The upper spray head 802 of the double-layer water pipe 801 has a smaller orifice diameter and requires less water, thus allowing for continuous operation. The number of spray heads 802 activated is adjusted in real-time according to the fire temperature to avoid waste. During operation, the water mist sprayed from the spray head 802 gathers on the top area of ​​the protective cap 3. Some of the water mist evaporates, continuously cooling the top area, while the unevaporated water mist falls to the top of the protective cap 3 and flows down in streams. At this time, the water flow is guided to both sides through the herringbone groove 803 on the forehead, preventing sewage mixed with smoke and dust from flowing towards the transparent baffle 805 and obstructing vision. The lower sprinkler head 804 has a relatively larger orifice diameter and is activated periodically. When the amount of smoke and dust is small, the sprinkler head 804 sprays water downwards to clean the transparent baffle 805 and maintain its visual clarity. When the amount of smoke and dust is large, the emergency mode is activated, keeping the sprinkler head 804 constantly open. At this time, rescuers can also manually squeeze the composite rubber water bag 808 to increase the water jet's impact force and quickly clean the surface of the transparent baffle 805. The water volume can be flexibly adjusted to prevent smoke and dust residue from obstructing vision. The composite rubber water bag 808 hangs down on both sides of the cap curtain to the rescuer's shoulders. When the amount of smoke and dust is small, there is no need to fill it with water, and the rescuer does not need to carry any weight. When the amount of smoke and dust is large, the valve of the conduit 807 is opened to fill it with water. The composite rubber water bag 808 utilizes the shoulder to bear the weight, preventing dragging of the protective cap 3. Furthermore, after being squeezed to increase pressure, the composite rubber water bag 808 automatically springs back to fill with water, facilitating the next use. Furthermore, when rescuers squeeze the composite rubber water bag 808, water is simultaneously squeezed into the arc-shaped sleeve 8012. The water pressure pushes the telescopic rod 8013 along the inner cavity of the protective cap 3, while the rotating shaft drives the cloth brush 8010 to wipe the inner surface of the transparent baffle 805, removing water mist and other impurities. Combined with the external water spray head 804 cleaning the transparent baffle 805, a dual cleaning effect is achieved inside and out. When the composite rubber water bag 808 absorbs water, it draws the water back from the arc-shaped sleeve 8012, causing the cloth brush 8010 to reset. Whenever the cloth brush 8010 returns to the position of the trapezoidal block 8014, the inclined groove on the double-groove plate 8015 presses against the trapezoidal block 8014, causing the double-groove plate 8015 to be pushed upwards to compress the spring, releasing the limit on the gear 8016. Therefore, the gear 8016 can mesh with the rack 8017 behind it, causing the cloth brush 8010 to rotate and switch to a new side facing the transparent baffle 805. Next, the brush 8010 passes completely through the trapezoidal block 8014, and the double-groove plate 8015, under the action of elasticity, engages downward with the gear 8016, locking the current position. When the telescopic rod 8013 pushes the brush 8010 out again, the double-groove plate 8015 passes through the trapezoidal block 8014 and can compress it only within the protective cap 3, without affecting the normal movement of the brush 8010.
