Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of emergency rescue protection equipment, especially relates to a portable fire shelter of quick deployment. BACKGROUND

[0002] In recent years, Yunnan has been in a state of continuous drought, and forest fires have been high-risk for several years. Multiple forest fires occur every year. The characteristics of forest fires are greatly influenced by topography, vegetation type, and meteorological conditions. Yunnan has complex and diverse terrain, with many continuous mountain ranges, high mountain valleys, gullies, and cliffs. The vegetation is complex and diverse, with dense patches of Yunnan pine and eucalyptus forests, mixed needle-leaf and broad-leaf forests, and various shrubs and grasses. The ground is covered with dry fallen leaves and branches, and the soil layer is thick. The weather is complex and diverse, with the strongest winds and most variable wind directions occurring from about 10am to 1-2 hours after sunset. Forest fires present complex and diverse characteristics, making it difficult to extinguish the fire and posing a serious threat to the safety of firefighters. Any carelessness can result in personal injury or death. During forest fire fighting, firefighters face the fire directly and are at risk of being trapped by the fire, high-temperature heat radiation, and smoke suffocation.

[0003] In the challenging and risky field of forest fire fighting, firefighters often face long-distance marches and complex terrain. They need to cross dense forests, climb mountains, and wade through valleys to reach the fire as quickly as possible. In addition to the necessary fire-fighting equipment, they must carry as much light as possible to reduce physical exertion and improve efficiency. However, the extreme conditions at the fire scene pose a serious threat to their safety. According to statistics, being trapped by the raging flames and being exposed to high-temperature environments and hot smoke are the main causes of injury and death among firefighters during forest fire fighting.

[0004] To effectively address this serious challenge and protect the lives of firefighters, domestic and foreign experts and scholars have invested a lot of time and effort in various technical innovation research to develop fire shelters that can provide emergency protection. However, despite these efforts, existing fire shelters have generally been large, inconvenient to carry, and time-consuming to deploy. These problems not only affect the mobility and flexibility of firefighters, but also may delay valuable escape time in critical situations, posing a potential threat to the safety of firefighters.

[0005] Therefore, developing a portable and quickly deployable fire shelter that is both lightweight and easy to carry is of great significance to improve the efficiency and safety of forest fire fighting. Such a fire shelter can provide effective protection for firefighters in emergency situations, reducing their risk of being exposed to high temperatures and hot smoke, thereby ensuring their safety.

[0027] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model. The following will be further described in combination with the drawings and examples. Figs. 1-2 The portable fireproof cover is further described.

[0028] Example 1

[0029] A portable fireproof cover, comprising a cover 1, a bottom edge 2, a storage fixing belt 3, the shape of the cover 1 is hemispherical, the lower edge of the hemispherical cover 1 is provided with the bottom edge 2, the bottom edge 2 is provided with the storage fixing belt 3, the material of the cover 1 is fireproof material. The cover 1 comprises a first cover surface 11, a second cover surface 12, a third cover surface 13 and a fourth cover surface 14, the first cover surface 11, the second cover surface 12, the third cover surface 13 and the fourth cover surface 14 are sequentially connected to form a hemispherical shape.

[0030] The bottom edge 2 is formed by the inward rolling and suturing of the lower edge of the cover 1. The lower edge of the cover 1 is inwardly rolled and sutured to form a cavity structure, the storage fixing belt 3 passes through the cavity structure of the bottom edge 2, and the two ends of the storage fixing belt 3 extend out of the cavity structure.

[0031] The cover 1 and the bottom edge 2 are integrally formed.

[0032] The first cover surface 11, the second cover surface 12, the third cover surface 13 and the fourth cover surface 14 are integrally formed. The cover 1 is composed of aluminum foil composite flame-retardant fabric and natural fiber fabric.

[0033] Working principle:

[0034] Compact structure: the fireproof cover realizes the compactness of volume and the reduction of weight through the design of the hemispherical cover 1 and the cavity structure formed by the inward rolling and suturing of the bottom edge 2. This design makes the fireproof cover convenient to roll up and fix when not in use, and convenient to carry;

[0035] Quick deployment: The storage fixing belt 3 passes through the cavity structure of the bottom edge 2, and the two ends extend outside the cavity structure, so that the fire hood can be quickly deployed when needed. Firefighters only need to untie the storage fixing belt 3 to deploy the fire hood into a hemispherical shape, covering the head and upper body, providing timely protection. When in use, the storage fixing belt 3 is tightened to the ground, and the body is in a squatting position, which can effectively block external hot smoke and prevent heat radiation from burning the body.

[0036] Fireproof performance: The cover body 1 is composed of aluminum foil composite flame-retardant fabric and natural fiber fabric. This combination of materials has excellent fireproof performance. The aluminum foil composite flame-retardant fabric can effectively block high temperature and flame, and the addition of natural fiber fabric improves the comfort and air permeability of the fire hood.

[0037] Working process

[0038] Carrying stage: On the way to the fire scene, firefighters roll up the fire hood and fix it at the waist or other convenient positions for carrying. Because the fire hood body 1 is compact and light in weight, it does not greatly affect the mobility of firefighters.

[0039] Preparation stage: When firefighters arrive near the fire scene and feel the threat of high temperature or flame, they quickly stop and prepare to deploy the fire hood. At this time, firefighters untie the storage fixing belt 3 and release the fire hood from the rolled-up state.

[0040] Deployment stage: The fire hood quickly forms a hemispherical shape covering the head and upper body of the firefighter during deployment. Due to the combined action of the cavity structure formed by the inner roll stitching of the bottom edge 2 and the storage fixing belt 3, the fire hood can stably maintain the deployed state. By tightening the storage fixing belt 3 to the ground and assuming a squatting position, external hot smoke can be effectively blocked, preventing heat radiation from burning the body, and providing comprehensive protection for firefighters.

[0041] Protection stage: Under the protection of the fire hood, firefighters can continue to carry out fire extinguishing operations or evacuate to a safe area. The fireproof material of the fire hood can effectively block high temperature and flame, protecting firefighters from injury.

[0042] Storage stage: After the fire hood is used, firefighters roll it up again and fix it at the waist or other convenient positions for carrying, so that it can be used again when needed.

[0043] Example 2

[0044] In view of the problems of the prior art, the utility model realizes that the fire hood is small in size, light in weight, convenient to carry, and can be quickly deployed, with a deployment time of less than 15s, thereby improving the applicability of the fire hood.
