A wear-resistant nylon mesh cloth is laminated on the outside of the aramid fiber.

[0015] Working principle: The user can put on the rescue suit quickly and conveniently through the first waterproof zipper. The second waterproof zipper enables the user to use the toilet when necessary. In a dim or harsh rescue environment, the reflective strips make it easier for rescuers to be noticed by other rescuers, boats or people on the shore. The protective sleeves provide additional physical protection for the user's key joint parts such as the knees and elbows. By integrating a water flow sensor, a water depth pressure sensor, a camera, a heart rate and blood oxygen sensor, a locator, a wireless communicator, and a temperature sensor on the rescue suit, all-round real-time monitoring and information interaction of the rescue site environment and the rescuers' own status are achieved, enabling rescuers to obtain key information in a timely manner and the command center to conduct precise command;

[0016] With the setting of a compressed gas cylinder and an airbag, when a rescuer accidentally falls into the water or faces an emergency, the compressed gas cylinder can be triggered to inflate the airbag, causing the airbag to expand rapidly, thereby providing additional buoyancy and physical protection for the rescuer, increasing the survival probability of the rescuer in the water. The temperature sensor monitors the user's body temperature in real time. When the body temperature drops to a certain threshold, the solid-state battery powers the carbon fiber heating wire, and then the heating wire sleeve heats the user's joints to prevent the joints from becoming stiff during use, ensuring that the rescuer can maintain good physical flexibility in a cold water environment and enabling them to carry out rescue operations more efficiently and safely;

[0017] By setting a third waterproof zipper at the cuffs to connect the gloves and a fourth waterproof zipper at the trouser legs to connect the foot covers, and respectively setting a first water-blocking reflective sheet and a second water-blocking reflective sheet on one side of the zippers, the waterproof sealing and protection of the cuffs and trouser legs are enhanced, effectively preventing water from entering the inside of the rescue suit through the cuffs and trouser legs. At the same time, the water-blocking reflective sheets improve visibility in a dim environment, further ensuring the safety of rescuers;

[0018] By setting a first thermal insulation sleeve on the inner wall of the trouser legs, a second thermal insulation sleeve on the inner wall of the chest, a fourth thermal insulation sleeve on the inner wall of the abdomen, and a third thermal insulation sleeve on the inner wall of the back, and filling them with phase change materials such as n-octadecane, lauric acid, polyethylene glycol or hydrated salts, excellent thermal insulation effects on the key parts of the rescuer's body are achieved. And the intelligent temperature regulation characteristics of the phase change materials enable them to dynamically adjust the temperature according to the actual needs of the human body, avoiding the situations of over-insulation or insufficient insulation;

[0019] Through the multi-layer structure design of the rescue suit body with a thermal insulation layer, a waterproof and breathable layer, and a composite layer, and each layer is composed of high-performance materials such as aerogel thermal insulation felt, far-infrared ceramic fiber flocs, soft polyester fiber cotton, expanded polytetrafluoroethylene membrane, hydrophilic polyurethane film, polyester fiber fabric, aramid fiber, weather-resistant neoprene, and wear-resistant nylon mesh cloth, the comprehensive improvement of multiple properties of the rescue suit such as waterproof, breathable, heat-insulating, wear-resistant, and weather-resistant is achieved, so that the rescue suit can adapt to the complex and changeable water environment.

[0020] The present invention provides an intelligent dry multi-functional water rescue suit. It has the following beneficial effects:

[0021] 1. By integrating various sensors, cameras, locators, wireless communicators, electric heating wire sleeves and related supporting components on the rescue suit, the present invention realizes the all-round real-time monitoring and information interaction of the rescue site environment and the state of the rescue personnel themselves. As a result, the rescue personnel can obtain key information in a timely manner, and the command center can accurately command, effectively respond to various situations in the complex water rescue scenario, ensure the efficient and safe progress of the rescue operation, improve the practicability and adaptability of the rescue suit in the complex water rescue, and thus solve the problem that the traditional water rescue suit has a relatively single function and low practicability when facing complex waters.

[0022] 2. Through the setting of the first thermal insulation sleeve, the second thermal insulation sleeve, the fourth thermal insulation sleeve, and the third thermal insulation sleeve, and by selecting phase change materials such as n-octadecane, lauric acid, polyethylene glycol or hydrated salts for filling, the present invention can provide more accurate and continuous thermal insulation effect when the temperature fluctuates, greatly improving the operation ability and comfort of the rescue personnel in the low-temperature environment. Moreover, the intelligent temperature regulation characteristic of the phase change material enables it to dynamically adjust the temperature according to the actual needs of the human body, avoiding the situation of over-insulation or insufficient insulation, and providing a reliable guarantee for the long-term operation of the rescue personnel under cold conditions.

[0023] 3. Through the multi-layer structure design of the rescue suit body with a thermal insulation layer, a waterproof and breathable layer, and a composite layer, and each layer is composed of high-performance materials such as aerogel thermal insulation felt, expanded polytetrafluoroethylene membrane, and aramid fiber, the comprehensive improvement of multiple properties of the rescue suit such as waterproof, breathable, heat-insulating, wear-resistant, and weather-resistant is achieved, so that the rescue suit can adapt to the complex and changeable water environment. For example, the waterproof and breathable layer prevents water from entering and discharges moisture at the same time, the thermal insulation layer effectively insulates heat, and the composite layer provides strength and protection, thus realizing the optimal combination of the material properties of the rescue suit and creating a high-performance protective equipment.

[0024] 4. In the present invention, a third waterproof zipper is provided at the cuffs to connect the gloves, and a fourth waterproof zipper is provided at the leg openings to connect the foot covers.

An airbag 24 is installed on one side of the shoulder strap 8 away from the solid-state battery 26. A compressed gas cylinder 25 is arranged on one side of the airbag 24; A first waterproof zipper 9 is arranged in the middle of one side of the rescue suit body 1. A second waterproof zipper 10 is arranged at the crotch of the rescue suit body 1. A reflective strip 4 is fixedly connected to one side of the rescue suit body 1. Protective sleeves 11 are fixedly connected to the knees and elbows of the rescue suit body 1. Carbon fiber heating wires are evenly arranged inside the electric heating wire sleeve 18.

[0036] Specifically, through the setting of the water flow sensor 5, the water flow speed nearby is sensed in real time, so that the rescue personnel or the command center can timely understand the dynamic situation of the water flow at the rescue site, anticipate dangers in advance. For example, a rapid water flow may hinder the rescue operation or pose a threat to the safety of the rescue personnel themselves, so as to formulate a more reasonable rescue strategy and route.

[0037] Through the setting of the water depth pressure sensor 12, the water depth nearby is sensed in real time, which can help the rescue personnel determine the water depth information of their own location, judge whether they are in a dangerous depth area, and at the same time, it is also helpful to understand the general situation of the underwater terrain, such as whether they are close to steep slopes, deep pits, etc., to avoid accidents.

[0038] Through the setting of the heart rate and blood oxygen sensor 16, the heart rate and blood oxygen saturation of the user are monitored in real time, enabling rescue personnel to always grasp their physical condition and prevent physical discomfort or danger caused by overwork, lack of oxygen, etc. In high-intensity rescue work, physical fatigue and oxygen supply have an important impact on the action ability and decision-making ability of rescue personnel. Once abnormal heart rate or blood oxygen is detected, measures such as taking a rest and adjusting breathing can be taken in a timely manner to ensure their own safety.

[0039] Through the setting of the camera 6, the situation of the nearby water area is photographed in real time, so as to intuitively feedback the actual situation on the site to the command center or other rescue personnel, facilitating the command center to comprehensively understand information such as the environment of the rescue site and the location of the trapped personnel, and formulating a more accurate rescue plan. At the same time, the photographed video materials can also provide a basis for subsequent rescue summary and experience sharing.

[0040] Through the setting of the locator 23, the position of the user is located in real time, enabling the command center to accurately grasp the whereabouts of the rescue personnel. When the rescue personnel encounter danger or need support, their position can be quickly determined and rescue operations can be carried out, improving the rescue efficiency and success rate.

[0041] Through the setting of the wireless communicator 7, the user can communicate with the outside world, and the data collected by each sensor and the data photographed by the camera 6 are transmitted to the outside world in real time, thus realizing information interconnection between the rescue site and the command center. The command center can conduct remote command and decision-making based on these data and information, give timely guidance and suggestions to the rescue personnel, and at the same time facilitate the rescue personnel to seek help from the outside world in a timely manner when encountering problems, ensuring the smooth progress of the rescue work.

[0042] Through the setting of the temperature sensor 19, the body temperature of the user is monitored in real time. When the body temperature drops to a certain threshold, the solid-state battery 26 supplies power to the carbon fiber heating wire, and then the joint of the user is heated through the heating wire sleeve 18 to prevent the joints of the user from becoming stiff during use, ensuring that the rescue personnel can maintain good physical flexibility in a cold water environment, enabling them to carry out rescue operations more efficiently and safely, and at the same time reducing the accidental risks caused by inconvenient movement due to joint stiffness.

[0043] Through the setting of the compressed gas cylinder 25 and the airbag 24, when the rescue personnel encounter accidental drowning or face emergency dangerous situations such as being washed away by the current and losing consciousness, the compressed gas cylinder 25 can be triggered to inflate the airbag 24, causing the airbag 24 to expand rapidly, thereby providing additional buoyancy and physical protection for the rescue personnel, increasing the survival probability of the rescue personnel in the water, reducing the risk of injury, and helping the rescue personnel stay afloat in dangerous situations and wait for further rescue.

[0044] Through the provision of the first waterproof zipper 9, the user can wear the rescue suit conveniently and quickly, ensuring the sealing and convenience during the wearing process of the rescue suit, effectively preventing water from seeping into the interior of the rescue suit through the zipper gap, and at the same time facilitating rapid dressing and engaging in rescue work in case of emergency. Through the provision of the second waterproof zipper 10, it is convenient for the user to use the toilet when necessary, and on the premise of ensuring the overall waterproof performance of the rescue suit, it solves the physiological needs problem of rescue personnel when wearing the rescue suit for a long time, improving the practicality and wearing comfort of the rescue suit.

[0045] Through the provision of the reflective strip 4, in a dim or harsh rescue environment, such as at night, in foggy weather, etc., the visibility of rescue personnel can be significantly improved, making it easier for rescue personnel to be discovered by other rescue personnel, boats or shore personnel, reducing the probability of accidental collisions and other accidents due to poor visibility during the rescue process, and ensuring the safety of rescue personnel. Through the provision of the protective sleeve 11, it provides additional physical protection for key joint parts such as the user's knee joints and elbow joints, reducing the damage that may be caused to the joints due to collisions, friction, etc. during the rescue process, enhancing the protective performance of the rescue suit, ensuring the safety of the joints of rescue personnel in a complex environment, and enabling them to carry out rescue operations with more confidence.

[0046] By integrating a water flow sensor 5, a water depth pressure sensor 12, a camera 6, a heart rate and blood oxygen sensor 16, a locator 23, a wireless communicator 7, a heating wire sleeve 18 and related supporting components such as a temperature sensor 19, a solid-state battery 26, etc. on the rescue suit, it realizes the all-round real-time monitoring and information interaction of the rescue site environment and the rescue personnel's own status. Thus, rescue personnel can obtain key information in a timely manner, the command center can conduct precise command, effectively respond to various situations in complex water rescue scenarios, ensure the efficient and safe progress of rescue operations, and thus achieve a high degree of integration and intelligence of the rescue suit functions, greatly enhancing the practicality and adaptability of the rescue suit in complex water rescue, and thus solving the problem that traditional water rescue suits have relatively single functionality and low practicality when facing complex waters.

[0047] Please refer to the appendix Figure 1 - appendix Figure 3 Please refer to the appendix, on both sides of the cuffs of the rescue suit body 1, a third waterproof zipper 15 is fixedly connected. On one side of the cuffs of the rescue suit body 1, a glove 3 is connected through the third waterproof zipper 15, and a first water-blocking reflective sheet 2 is arranged on one side of the third waterproof zipper 15; on one side of the leg openings of the rescue suit body 1, a fourth waterproof zipper 30 is fixedly connected. On one side of the leg openings of the rescue suit body 1, a foot cover 13 is connected through the fourth waterproof zipper 30, and a second water-blocking reflective sheet 14 is arranged on one side of the foot cover 13.

[0048] Specifically, by setting a third waterproof zipper 15 at the cuffs to connect the gloves 3 and a fourth waterproof zipper 30 at the leg openings to connect the foot covers 13, and respectively setting a first water-blocking reflective sheet 2 and a second water-blocking reflective sheet 14 on one side of the zippers, the waterproof sealing and protection at the cuffs and leg openings are enhanced, effectively preventing water from entering the interior of the rescue suit through the cuffs and leg openings. At the same time, the water-blocking reflective sheets improve visibility in low-light environments, further ensuring the safety of rescue personnel, thus realizing the multi-functional optimization of the cuffs and leg openings, ensuring both waterproofness and having protection and warning functions, and solving the problems of easy water ingress, insufficient protection, and poor visibility in low-visibility environments at the cuffs and leg openings of traditional rescue suits.

[0049] Please refer to the attached Figure 1 - attached Figure 3 , the output end of the compressed gas cylinder 25 is located inside the airbag 24. First thermal insulation sleeves 17 are provided on the inner walls of the legs of the rescue suit body 1, a second thermal insulation sleeve 20 is provided on the inner wall of the front chest of the rescue suit body 1, a fourth thermal insulation sleeve 22 is provided on the inner wall of the abdomen of the rescue suit body 1, and third thermal insulation sleeves 21 are evenly provided on the inner wall of the back of the rescue suit body 1; thermal insulation materials are filled inside the first thermal insulation sleeve 17, the second thermal insulation sleeve 20, the third thermal insulation sleeve 21, and the fourth thermal insulation sleeve 22, and the thermal insulation materials are one of n-octadecane, lauric acid, polyethylene glycol, or hydrated salts.

[0050] Specifically, by setting a first thermal insulation sleeve 17 on the inner wall of the legs, a second thermal insulation sleeve 20 on the inner wall of the front chest, a fourth thermal insulation sleeve 22 on the inner wall of the abdomen, and a third thermal insulation sleeve 21 on the inner wall of the back of the rescue suit body 1, and filling with phase change materials such as n-octadecane, lauric acid, polyethylene glycol, or hydrated salts, excellent thermal insulation effects on the key parts of the rescue personnel's body are achieved. These phase change materials have unique physical properties and can undergo phase changes within a specific temperature range, such as changing from solid to liquid or vice versa. In a cold water environment, when the body temperature of the rescue personnel causes the phase change materials to reach their phase change temperature, the materials will undergo a phase change process, during which a large amount of latent heat is absorbed or released, thus effectively reducing heat loss and maintaining the body temperature of the rescue personnel stable. Compared with traditional thermal insulation materials, phase change materials can provide more accurate and continuous thermal insulation effects during temperature fluctuations, greatly improving the operation ability and comfort of rescue personnel in low-temperature environments.

[0051] Moreover, the design of this multi-part thermal insulation cover combined with phase change materials has achieved a significant improvement and targeted optimization in the overall thermal insulation performance of the rescue suit. It can not only comprehensively cover the key areas of the body that are prone to heat dissipation, but also the intelligent temperature regulation characteristics of the phase change materials enable it to dynamically adjust the temperature according to the actual needs of the human body, avoiding the situations of over-insulation or insufficient insulation. Thus, it effectively solves the problem that traditional rescue suits have poor thermal insulation effect in low-temperature waters, which affects the work efficiency and physical condition of rescue personnel. Traditional rescue suits often can only provide single static thermal insulation and are difficult to adapt to the complex and changeable low-temperature water environment and the dynamic heat demand of the human body. However, the phase change material-filled thermal insulation structure of this design can better meet the thermal insulation requirements in actual rescue scenarios and provide reliable protection for rescue personnel during long-term operations in cold conditions.

[0052] Please refer to the attached Figure 4 - attached Figure 7 , the rescue suit body 1 includes a thermal insulation layer 29. The outer side of the thermal insulation layer 29 is fixedly connected with a waterproof and breathable layer 27, and the outer side of the waterproof and breathable layer 27 is fixedly connected with a composite layer 28; the thermal insulation layer 29 includes an aerogel thermal insulation felt 291, a far-infrared ceramic fiber flake 292 is laminated on the inner side of the aerogel thermal insulation felt 291, a soft polyester fiber cotton 293 is compounded on the outer side of the aerogel thermal insulation felt 291, and the outer side of the soft polyester fiber cotton 293 is fixedly connected to the inner side of the waterproof and breathable layer 27; the waterproof and breathable layer 27 includes an expanded polytetrafluoroethylene membrane 271, a hydrophilic polyurethane film 272 is laminated on the inner side of the expanded polytetrafluoroethylene membrane 271, the inner side of the hydrophilic polyurethane film 272 is fixedly connected to the outer side of the thermal insulation layer 29, a polyester fiber fabric 273 is compounded on the outer side of the expanded polytetrafluoroethylene membrane 271, and the outer side of the polyester fiber fabric 273 is fixedly connected to the inner side of the composite layer 28; the composite layer 28 includes aramid fibers 281, a weather-resistant neoprene 282 is laminated on the inner side of the aramid fibers 281, the inner side of the weather-resistant neoprene 282 is fixedly connected to the outer side of the waterproof and breathable layer 27, and a wear-resistant nylon mesh cloth 283 is compounded on the outer side of the aramid fibers 281.

[0053] Specifically, the expanded polytetrafluoroethylene membrane 271 has an extremely small pore structure, which can allow water vapor molecules to pass smoothly, thereby achieving efficient breathability, while effectively preventing the intrusion of liquid water to ensure the waterproof function. A hydrophilic polyurethane film 272 is pressed on the inside thereof. The hydrophilic polyurethane film 272 can not only further enhance the waterproof performance of the waterproof and breathable layer 27, but also can quickly diffuse and conduct the sweat emitted by the human body to the outer layer through its special molecular structure, thereby accelerating the evaporation of sweat and improving the dryness and comfort of wearing. In addition, a polyester fiber fabric 273 is compounded on the outside of the expanded polytetrafluoroethylene membrane 271, which has high strength and good wear resistance, and can provide effective physical protection for the expanded polytetrafluoroethylene membrane 271 to prevent it from being scratched or damaged when subjected to external forces, thereby ensuring the long-term stability and reliability of the waterproof and breathable layer 27.

[0054] The aramid fiber 281 has excellent tensile strength and tear resistance, and is not easy to break when subjected to large external forces. It can significantly enhance the overall structural strength of the rescue suit and effectively resist puncture and friction from sharp objects. The weather-resistant chloroprene rubber 282 is pressed on the inside. The chloroprene rubber has good weather resistance, flexibility and sealing performance, and can maintain stable performance under various harsh water environment conditions. It can fit tightly on the outside of the waterproof and breathable layer 27 to prevent moisture from penetrating from the outside into the gap between the composite layer 28 and the waterproof and breathable layer 27. At the same time, it also provides a certain degree of elasticity and comfort for the rescue suit. In addition, the wear-resistant nylon mesh cloth 283 is compounded on the outside of the aramid fiber 281. The nylon mesh cloth has excellent wear resistance and air permeability. Its mesh structure can further enhance the wear resistance of the composite layer 28 while ensuring a certain degree of flexibility, and is conducive to air circulation, so that the rescue suit will not be too stuffy while having good protective performance.

[0055] Aerogel insulation felt 291 is a highly efficient thermal insulation material with extremely low thermal conductivity. It can prevent heat conduction to a great extent, effectively maintain the temperature inside the rescue suit, and reduce the loss of human heat to the external environment. Far-infrared ceramic fiber flakes 292 are pressed on the inside. The far-infrared ceramic fiber flakes 292 can absorb the far infrared rays emitted by the human body and reflect them back to the human body, forming a heat cycle, thereby improving the thermal insulation effect. At the same time, it also has antibacterial and mildew-proof functions, which helps to maintain the sanitary environment inside the rescue suit. Soft polyester fiber cotton 293 is compounded on the outside of the aerogel insulation felt 291. The polyester fiber cotton is soft and light in texture and has certain thermal insulation properties. It can make the thermal insulation layer 29 and the waterproof and breathable layer 27 fit better, fill the tiny gaps that may exist between the two, avoid heat loss through air convection, and also increase the comfort of wearing.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
