Description

Technical Field

[0001] This invention relates to the field of fire rescue and protection, and in particular to a high-temperature resistant high-silica-oxygen composite aerogel life jacket for use in fire scenarios. Background Technology

[0002] During a fire, the scene is often characterized by harsh environments such as high-temperature heat radiation, open flames, toxic fumes, and oxygen deficiency. When firefighters enter a high-temperature, dense-smoke fire scene to carry out firefighting, search and rescue, demolition, and emergency operations, they are exposed to temperatures above 1000°C, strong heat radiation, molten materials, and high concentrations of toxic fumes for extended periods. This can easily cause deep skin burns, respiratory poisoning, suffocation, or even death. The protective risks are far greater than in ordinary escape scenarios, and fire life jackets are one of the important protective equipment used by firefighters.

[0003] Currently available conventional fire life jackets have a simple structure, mostly made of single-layer flame-retardant fabric, which has poor high-temperature resistance and insulation performance. When exposed to high-temperature fire environments for extended periods, the fabric is prone to carbonization and damage, resulting in a short protective lifespan. In addition, the existing life jackets have a simple wearing structure, mostly using a single zipper for opening and closing, with weak sealing protection at the zipper, allowing high-temperature smoke in the fire to easily penetrate the gaps. The neck fit structure is also simple, unable to adapt to different neck sizes, resulting in poor sealing. Furthermore, many traditional life jackets have a split structure, with loose connections between the body, hood, and oxygen supply components, resulting in poor sealing. Smoke and fire can easily penetrate the interior through the seams, leading to insufficient protective reliability and poor stability. Moreover, most life jackets lack an integrated oxygen supply structure, making it difficult to meet the protection needs of firefighters during high-intensity, long-term fire operations. Under complex fire conditions, components are prone to loosening and falling off, greatly reducing the survival rate in fire rescues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-temperature resistant high-silica-oxygen composite aerogel life jacket for fire scenarios, so as to solve the problems of poor high-temperature resistance, weak sealing, lack of integrated oxygen supply function, loose structure, inconvenience of wearing, poor adaptability, and inability to meet the high-intensity protection requirements of fire rescue scenarios.

[0005] To address the aforementioned problems, the present invention is implemented through the following technical solution.

[0006] A high-temperature resistant, high-silica-oxygen composite aerogel life jacket for fire scenarios includes: an upper garment with symmetrical sleeves on both sides, and protective gloves at the ends of the sleeves away from the upper garment; trousers integrated with the upper garment on the lower side of the upper garment; protective boots at the ends of the trousers away from the upper garment; an elastic neck collar fixedly connected to the ends of the upper garment away from the trousers; a hood at the ends of the elastic neck collar away from the upper garment; a high-transparency protective face shield embedded in the front of the hood; an oxygen supply mechanism at the mouth and nose of the hood; a protective splicing connection mechanism for connecting the hood to the upper garment on the side of the hood near the upper garment; and a double-layer easy-wearing component in the center of the front of the upper garment.

[0007] In one embodiment, the oxygen supply mechanism includes a cylinder fixing sleeve, an oxygen cylinder, an oxygen supply delivery tube, and a mouth and nose respirator, with the cylinder fixing sleeve located on the back of the upper garment.

[0008] In one embodiment, the oxygen cylinder is detachably installed inside the cylinder fixing sleeve, the mouth and nose respirator is located inside the head cover at the corresponding position of the mouth and nose, and the oxygen cylinder is connected to the mouth and nose respirator through an oxygen supply pipe.

[0009] In one embodiment, the protective splicing and connecting mechanism includes a fireproof and heat-insulating shawl, a hook-and-loop fastener side, and a loop-and-loop fastener side. The fireproof and heat-insulating shawl is wrapped around the shoulder area where the top, hood, and gas cylinder fixing sleeve connect, and the fireproof and heat-insulating shawl is an integrally formed structure.

[0010] In one embodiment, the first hook side of the hook and loop fastener is disposed on the inside of the fireproof and heat-insulating shawl, and the first loop fastener is disposed on the upper garment and the gas cylinder fixing sleeve at the same location as the hook and loop fastener. The head cover is connected to the upper garment and the gas cylinder fixing sleeve by the adhesive cooperation of the first hook and loop fastener and the first loop fastener.

[0011] In one embodiment, the dual-layer convenient wearable component includes a first sealed zipper, a second sealed zipper, a zipper head, a fireproof sticker, a second hook and loop fastener, and a second loop fastener. The first sealed zipper and the second sealed zipper are arranged vertically side by side in the middle of the front of the garment, and the zipper head is slidably mounted on the first sealed zipper and the second sealed zipper.

[0012] In one embodiment, the fireproof sticker is disposed on the outside of the sealed zipper. One side of the fireproof sticker is integrally formed with the upper garment. The movable side of the fireproof sticker facing the upper garment has a second hook and loop fastener. The upper garment has a second hook and loop fastener corresponding to the second hook and loop fastener. The fireproof sticker is connected to the upper garment by the adhesive cooperation of the second hook and loop fastener.

[0013] In one embodiment, the top, sleeves, trousers, protective boots, and gas cylinder fixing sleeve are integrally molded structures, and the hood and fireproof and heat-insulating shawl are integrally molded structures.

[0014] In one embodiment, the top, sleeves, trousers, headgear, fireproof and heat-insulating shawl, and gas cylinder fixing sleeve are all made of a double-layer composite material consisting of an outer layer of silicone-sprayed high-silica glass fiber cloth and an inner layer of high-silica composite aluminum silica aerogel felt. The high-silica composite aluminum silica aerogel felt is formed by pressing high-silica glass fiber felt and aluminum silica aerogel together.

[0015] In one embodiment, the high-transparency protective face mask is made of high-temperature resistant transparent flame-retardant material, and the high-transparency protective face mask and the head cover are sealed and embedded. The elastic neck sleeve is made of flame-retardant elastic rubber material and has a stretchable elastic structure with annular pleats. The elastic neck sleeve is set at the neck position of the upper garment and relies on its own pleat stretchable characteristics to fit the periphery of the human neck, forming a self-adaptive tightness sealing protective structure.

[0016] This invention provides a high-temperature resistant, high-silica-oxygen composite aerogel life jacket for use in fire scenarios. Compared with existing technologies, it has the following advantages: This invention integrates the top, sleeves, trousers, protective boots, and gas cylinder fixing sleeve into a single molded structure. The headgear and fireproof and heat-insulating shawl are also molded as a single piece, reducing seams and structurally reducing the risk of smoke and fire penetration. It is paired with a pleated elastic neck warmer that can adapt to fit the necks of different people, sealing gaps in the neck and further improving the overall sealing and protection capabilities. It meets the sealing and protection needs of firefighters for quick donning and high-intensity activities. This invention uses a double-layer composite material consisting of an outer layer of silicone-sprayed high-silica glass fiber cloth and an inner layer of high-silica composite aluminosilicate aerogel felt. The outer silicone layer is resistant to open flame, radiation heat, and corrosion, while the inner aluminosilicate aerogel layer has an extremely low thermal conductivity and excellent heat insulation performance. It can block the transmission of high temperature for a long time in high-temperature fire environments, and its high-temperature insulation can reach 1300 degrees Celsius, preventing the human body from being burned by high temperature. The material structure is stable, not easy to carbonize and break, and has a long service life, which can meet the heat insulation and protection requirements of fire rescue personnel who need to enter high-temperature fire environments for a short time. This invention integrates a detachable oxygen cylinder on the back of the jacket, which is connected to the mouth and nose respirator inside the headgear through an oxygen supply tube. In the oxygen-deficient and toxic smoke environment of a fire, it can provide clean oxygen for firefighters, avoid smoke poisoning and suffocation, and greatly improve the survival rate of fire escape. Featuring a double-layered, parallel sealed zipper, combined with a fully covered fireproof outer layer and Velcro fastening, this double-sealed protection overcomes the shortcomings of traditional single-zipper protection, such as large gaps and poor heat insulation. It effectively blocks high-temperature smoke and open flames from entering through the openings. A fireproof and heat-insulating shawl serves as an auxiliary connecting structure, using Velcro to reinforce and secure the hood, jacket, and gas cylinder cover, preventing the hood from loosening or shifting during firefighting activities. It also provides heat insulation and sealing for the shoulder joints, offering enhanced overall protection and adapting to complex scenarios such as climbing and demolition by firefighters.

[0027] The oxygen supply mechanism 8 includes a cylinder fixing sleeve 801, an oxygen cylinder 802, an oxygen supply delivery pipe 803, and a mouth and nose respirator 804. The cylinder fixing sleeve 801 is located on the back of the upper garment 1.

[0028] The oxygen cylinder 802 is detachably installed inside the cylinder fixing sleeve 801, and the mouth and nose respirator 804 is located inside the head cover 6 at the corresponding positions of the mouth and nose. The oxygen cylinder 802 is connected to the mouth and nose respirator 804 through the oxygen supply pipe 803.

[0029] The protective splicing and connecting mechanism 9 includes a fireproof and heat-insulating shawl 901, a hook and loop fastener 902, and a loop and loop fastener 903. The fireproof and heat-insulating shawl 901 is wrapped around the shoulder area where the upper garment 1 connects with the head cover 6 and the gas cylinder fixing sleeve 801, and the fireproof and heat-insulating shawl 901 is an integrally formed structure.

[0030] The hook and loop fastener 902 is located on the inside of the fireproof and heat-insulating shawl 901, and the loop fastener 903 is located on the upper garment 1 and the gas cylinder fixing sleeve 801 at the corresponding hook and loop fastener 902. The head cover 6 is connected to the upper garment 1 and the gas cylinder fixing sleeve 801 by the adhesive cooperation of the hook and loop fastener 902 and the loop fastener 903.

[0031] The double-layer convenient wearable component 11 includes a sealed zipper 1101, a sealed zipper 2 1102, a zipper head 1103, a fireproof patch 1104, a hook and loop fastener 2 1105, and a loop fastener 2 1106. The sealed zipper 1101 and the sealed zipper 2 1102 are arranged vertically side by side in the middle of the front side of the top 1. The zipper head 1103 is slidably installed on the sealed zipper 1101 and the sealed zipper 2 1102.

[0032] Fireproof sticker 1104 is installed on the outside of the sealed zipper. One side of fireproof sticker 1104 is integrally formed with the top 1. The movable side of fireproof sticker 1104 facing the top 1 has a hook and loop fastener 1105. The top 1 has a hook and loop fastener 1106 corresponding to the hook and loop fastener 1105. The fireproof sticker 1104 is connected to the top 1 through the adhesive cooperation of the hook and loop fastener 1105 and the hook and loop fastener 1106.

[0033] The top 1, sleeves 2, trousers 4, protective boots 5, and gas cylinder fixing sleeve 801 are all integrally molded structures, as are the head cover 6 and fireproof and heat-insulating shawl 901.

[0034] The top 1, sleeves 2, trousers 4, head cover 6, fireproof and heat-insulating shawl 901, and gas cylinder fixing sleeve 801 are all made of a double-layer composite material consisting of an outer layer of silicone-sprayed high-silica glass fiber cloth and an inner layer of high-silica composite aluminum silica aerogel felt. The high-silica composite aluminum silica aerogel felt is made by pressing high-silica glass fiber felt and aluminum silica aerogel together.

[0035] The high-transparency protective face mask 7 is made of high-temperature resistant transparent flame-retardant material, and the high-transparency protective face mask 7 and the head cover 6 are sealed and embedded. The elastic neck sleeve 10 is made of flame-retardant elastic rubber material and has a stretchable elastic structure with ring-shaped pleats. The elastic neck sleeve 10 is set at the neck position of the upper garment 1 and relies on its own pleated stretchable characteristics to fit the sides of the human neck, forming a self-adaptive tight and sealed protective structure.

[0036] During use, firefighters use the double-layer convenient wearable component 11 to complete the opening and closing of the garment. By pulling the zipper head 1103, they simultaneously control the opening and closing of the sealing zipper one 1101 and the sealing zipper two 1102, placing the torso and limbs into the upper garment 1, sleeves 2, and trousers 4 in sequence, so that the hands are inserted into the protective gloves 3 and the feet are inserted into the protective boots 5, completing the sealing of the limbs. After wearing, the fireproof patch 1104 is folded over so that the hook and loop side 1105 on the surface of the fireproof patch 1104 and the hook and loop side 1106 on the surface of the upper garment 1 are adhered to each other, covering the sealing zipper one 1101 and the sealing zipper two 1102, sealing the gap in the front of the garment, and achieving double sealing protection of the front of the garment. After putting on the clothing, the head cover 6 is placed over the head. The elastic neck sleeve 10 at the neck position of the upper garment 1 fits and seals the neck. The elastic neck sleeve 10 adopts a ring-shaped pleated elastic structure, which can adapt to the contour of the human neck and prevent smoke and fire from entering the upper garment 1 through the neck gap. The high-transparency protective mask 7 embedded in the front of the head cover 6 blocks external high temperature smoke and open flames, while ensuring that the external observation vision of firefighters is transparent, thus achieving facial isolation protection. After the headgear 6 is put on, the protective splicing and connecting mechanism 9 is used for reinforcement and limiting. The fireproof and heat-insulating shawl 901 is wrapped around the shoulder joint of the upper garment 1, headgear 6 and gas cylinder fixing sleeve 801. The Velcro hook side 902 on the inside of the fireproof and heat-insulating shawl 901 is attached to the Velcro loop side 903 on the surface of the upper garment 1 and gas cylinder fixing sleeve 801, thereby pulling and fixing the headgear 6 to prevent the headgear 6 from shifting or shaking during rescue operations or escape running. At the same time, it seals the shoulder splicing gaps and improves the overall airtightness. When firefighters enter a high-temperature fire scene to carry out firefighting, search and rescue, and demolition operations, the outer layer of the jacket 1, sleeves 2, trousers 4, protective boots 5, headgear 6, and fireproof and heat-insulating shawl 901 relies on the outer layer of silicone-sprayed high-silica fiberglass cloth to block open flames and heat radiation, and the inner layer of high-silica composite aluminosilicate aerogel felt to achieve efficient heat insulation. The high temperature insulation can reach 1300 degrees Celsius, preventing the human body from being burned by high temperature. The hands rely on protective gloves 3 to achieve flame-retardant and heat-insulating protection, and the feet rely on protective boots 5 to isolate the high temperature of the ground and open flames. In response to the oxygen-deficient and toxic smoke environment at the fire scene, the oxygen supply mechanism 8 independently completes the oxygen supply operation. The cylinder fixing sleeve 801 is fixed to the back of the upper garment 1 to limit and fix the oxygen cylinder 802 to prevent the cylinder from falling off and shaking. The oxygen cylinder 802 stores clean oxygen and delivers it steadily to the mouth and nose breathing apparatus 804 inside the headgear 6 through the oxygen supply delivery pipe 803. Firefighters breathe through the mouth and nose breathing apparatus 804 to isolate themselves from the external toxic smoke and avoid poisoning and suffocation. In summary, this invention provides full-body protection through a jacket 1, sleeves 2, protective gloves 3, trousers 4, and protective boots 5; it provides sealed protection for the head and neck through a hood 6, a high-transparency protective face mask 7, and an elastic neck glove 10; it provides independent oxygen supply in the fire scene through an oxygen supply mechanism 8; it reinforces the head connection and seals shoulder gaps through a protective splicing and connecting mechanism 9; and it utilizes a double-layer convenient wearable component 11 to achieve rapid donning and chest sealing. All the structures work together to form an integrated, fully enclosed, high-temperature resistant protective system that can continuously protect human safety in high-temperature, dense smoke, and oxygen-deficient fire environments. It can meet the protection needs of firefighters for short-term search and rescue operations, effectively improving the survival rate of fire escape and the safety of rescue operations. When in use, firefighters insert their limbs into the garment, pull the zipper 1103 to close the double-sealed zipper, fold the fireproof patch 1104, use Velcro to attach and seal it, place the hood 6 over their head, rely on the pleated elastic neck brace 10 to fit tightly against their neck, and then attach and fix the fireproof and heat-insulating shawl 901 on their shoulders to complete the overall wearing and fixing process. In a fire scene, the outer layer of the protective clothing, made of high-silica fiberglass cloth, isolates open flames and blocks heat radiation, while the inner layer, made of aluminosilicate aerogel felt, significantly blocks high-temperature conduction, preventing burns to the body surface. The high-transparency protective mask 7 isolates toxic fumes and dust while ensuring unobstructed vision. An oxygen cylinder 802 on the back delivers clean oxygen to the mouth and nose respirator 804 inside the headgear 6 via an oxygen supply pipe 803, enabling firefighters to breathe normally in dense smoke and oxygen-deficient environments, eliminating the risk of poisoning and suffocation.
