Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a protective shell for special fire rescue equipment with high fire protection performance. Background Technology

[0002] In the field of fire and rescue, specialized firefighting and rescue equipment plays a crucial role in the smooth operation of fire suppression and personnel rescue. However, fire scenes are often accompanied by extremely dangerous environments such as high temperatures, flames, and smoke, which places extremely high demands on the protection of specialized firefighting and rescue equipment.

[0003] Existing protective shells for special fire rescue equipment are made of ordinary plastics or composite materials, which have limited flame retardant properties. When exposed to open flames or high temperatures at a fire scene, they are prone to combustion or deformation and cannot effectively block flames and heat, thus threatening the safety of the internal rescue equipment. In addition, some protective shells use materials with high thermal conductivity, such as common metal materials or ordinary engineering plastics, which cannot effectively prevent external heat from entering. This causes the internal equipment to heat up rapidly in high-temperature environments, which may exceed the normal operating temperature range of the equipment, affecting its performance or even causing damage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a protective shell for special fire rescue equipment with high fire resistance.

[0005] This utility model is achieved using the following technical solution: a protective shell for fire-fighting special rescue equipment with high-efficiency fire resistance, comprising a protective shell, a protective door rotatably connected to the front end of the protective shell, a handle fixedly connected to the front end of the protective door, a transparent window provided inside the protective door, a water pipe fixedly connected to the left side of the protective door, a water spraying device provided on the surface of the protective door, a water trough opened at the top of the protective shell, and a water wall opened inside the protective shell;

[0006] The protective shell comprises a composite ceramic fiber material, with an aerogel insulation felt on one side of the composite ceramic fiber material, and an aramid fiber reinforced epoxy resin composite material on one side of the aerogel insulation felt.

[0007] Through the above technical solution, rescuers can view the operating status and storage conditions of the equipment inside the protective shell in real time through the transparent window without opening the protective door, thus avoiding damage from high temperatures and smoke and providing a basis for rescue decisions.

[0008] As a further improvement to the above solution, the composite ceramic fiber material, aerogel insulation felt and aramid fiber reinforced epoxy resin composite material are connected by hot pressing molding in an integrated composite process.

[0009] As a further improvement to the above solution, the aerogel insulation felt is designed with a honeycomb structure, and the honeycomb units are hexagonal.

[0010] As a further improvement to the above solution, the water inlet pipe is connected to the water wall.

[0011] Through the above technical solution, the water pipe is connected to an external water source to stably supply water to the water wall and sprinkler system, ensuring that the cooling function of the water wall and the fire extinguishing and cooling function of the sprinkler system remain effective during fire rescue. The water in the water wall can absorb heat from the inside of the protective shell, reduce the internal ambient temperature, create relatively safe working temperature conditions for the internal rescue equipment, and prevent the equipment from malfunctioning due to high temperature.

[0012] As a further improvement to the above solution, the water spraying device includes a connecting pipe, a rotating pipe connected to the top of the connecting pipe, a water spray head fixedly connected to the surface of the rotating pipe, and a rotating nozzle fixedly connected to the top of the rotating pipe.

[0013] As a further improvement to the above solution, the connecting pipe is located at the top of the water inlet pipe.

[0014] As a further improvement to the above solution, the connecting pipe is connected to the water inlet pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a composite ceramic fiber material, aerogel insulation felt, and aramid fiber-reinforced epoxy resin composite material. The protective shell is made of these three materials in a hot-pressed, integrated structure, ensuring close collaboration between the materials. The composite ceramic fiber material is heat-resistant, the aerogel insulation felt has low thermal conductivity and its honeycomb structure enhances insulation, and the aramid fiber-reinforced epoxy resin composite material guarantees strength. The combination of these three materials effectively blocks high temperatures, ensuring the equipment operates normally in fire environments.

[0017] This invention features a water inlet pipe, a water wall, a rotating pipe, and a rotating nozzle. The water inlet pipe is connected to the water wall, allowing external water to flow into it. The water in the water wall absorbs heat, lowering the temperature inside the protective casing and preventing fire from spreading inside. A connecting pipe is located at the top of the water inlet pipe and connects to it, allowing water to flow into the connecting pipe. The rotating pipe connects to the top of the connecting pipe, through which water is delivered to the nozzle and the rotating nozzle. The nozzle sprays water onto the surface of the protective casing, extinguishing fire and cooling the surrounding area. The rotating nozzle rotates to spray water, expanding the spray range and improving the fire extinguishing and cooling effects. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0025] Please combine Figure 1-4 This embodiment provides a protective shell for fire-fighting special rescue equipment with high fire resistance performance, including a protective shell 1, a protective door 2 rotatably connected to the front end of the protective shell 1, a handle 3 fixedly connected to the front end of the protective door 2, a transparent window 4 inside the protective door 2, a water pipe 5 fixedly connected to the left side of the protective door 2, a water spraying device 6 on the surface of the protective door 2, a water trough 7 on the top of the protective shell 1, and a water wall 8 inside the protective shell 1.

[0026] The protective outer shell 1 comprises a composite ceramic fiber material 11, with an aerogel insulation felt 12 on one side of the composite ceramic fiber material 11, and an aramid fiber reinforced epoxy resin composite material 13 on one side of the aerogel insulation felt 12. The protective outer shell 1 is formed by hot-pressing the composite ceramic fiber material 11, the aerogel insulation felt 12, and the aramid fiber reinforced epoxy resin composite material 13 together through a composite process. These three materials each possess unique properties, working together to provide fireproofing and heat insulation: Composite ceramic fiber material 11: The ceramic fiber material itself has excellent high-temperature resistance, capable of withstanding high-temperature environments and preventing high temperatures from directly penetrating the protective outer shell 1 and threatening the internal rescue equipment. Aerogel insulation felt 12: It has extremely low thermal conductivity, making it a highly efficient heat insulation material. The aerogel insulation felt 12 is designed with a honeycomb structure, and the honeycomb units are hexagonal. This structure not only effectively reduces heat transfer but also enhances the strength and stability of the material, further preventing heat from transferring inwards. Aramid fiber reinforced epoxy resin composite material 13: Aramid fibers have high strength and high modulus, while epoxy resin has good adhesion and corrosion resistance. This composite material can enhance the overall strength and durability of the protective shell 1, and also provide a certain degree of thermal insulation.

[0027] The composite ceramic fiber material 11, the aerogel insulation felt 12, and the aramid fiber reinforced epoxy resin composite material 13 are connected by a hot-pressing molding process that integrates the composite materials.

[0028] The aerogel insulation felt 12 is designed with a honeycomb structure, and the honeycomb units are hexagonal.

A water inlet pipe 5 is connected to a water wall 8, allowing external water to flow into the water wall 8. The water in the water wall 8 absorbs heat, reducing the internal temperature of the protective casing 1 and preventing the fire from spreading into the casing 1. The connecting pipe 61 is located at the top of the water inlet pipe 5 and is connected to it, allowing water to flow into the connecting pipe 61. A rotating pipe 62 is connected to the top of the connecting pipe 61, through which water is delivered to the spray head 63 and the rotating nozzle 64. The water nozzle 63 can spray water onto the surface of the protective housing 1 to extinguish fire and cool the area around the protective housing 1; the rotating nozzle 64 can rotate to spray water, expand the spray range, and improve the fire extinguishing and cooling effect. The water falls onto the protective housing 1 and is discharged from the water tank 7 at the top of the protective housing 1.

[0031] Connecting pipe 601 is located at the top of water inlet pipe 5.

[0032] The connecting pipe 601 is connected to the water inlet pipe 5.

[0033] The implementation principle of a fire-fighting special rescue equipment protective shell with high-efficiency fire resistance in this embodiment is as follows: The protective shell 1 is formed by hot pressing through a composite process, using a composite process to integrally mold composite materials 11, aerogel insulation felt 12, and aramid fiber reinforced epoxy resin composite material 13. These three materials each possess unique properties and work together to provide fire resistance and heat insulation: Composite ceramic fiber material 11: Ceramic fiber material itself has excellent high-temperature resistance, capable of withstanding high-temperature environments and preventing high temperatures from directly penetrating the protective shell 1 and threatening the internal rescue equipment. Aerogel insulation felt 12: It has extremely low thermal conductivity and is a highly efficient heat insulation material. The aerogel insulation felt 12 is designed with a honeycomb structure, and the honeycomb units are hexagonal. This structure not only effectively reduces heat transfer but also enhances the strength and stability of the material, further blocking heat transfer to the interior. Aramid fiber reinforced epoxy resin composite material 13: Aramid fibers have high strength and high modulus, while epoxy resin has good adhesion and corrosion resistance. This composite material can enhance the overall strength and durability of the protective shell 1, while also providing a certain degree of heat insulation. Then, the water pipe 5 is connected to the water wall 8, allowing external water to flow into the water wall 8. The water in the water wall 8 absorbs heat, reducing the internal temperature of the protective shell 1 and preventing the fire from spreading inside the protective shell 1. The connecting pipe 61 is located at the top of the water pipe 5 and is connected to it, allowing water to flow from the water pipe 5 into the connecting pipe 61. A rotating pipe 62 is connected to the top of the connecting pipe 61, through which water is delivered to the spray head 63 and the rotating nozzle 64. The spray head 63 sprays water onto the surface of the protective shell 1, extinguishing the fire and cooling the area around it. The rotating nozzle 64 rotates to spray water, expanding the spray range and improving the extinguishing and cooling effect. Water falls onto the protective shell 1 and is discharged from the water tank 7 at the top of the protective shell 1. Finally, a transparent window 4 is provided at the front of the protective door 2, allowing rescuers to observe the interior of the protective shell 1 without opening the protective door 2, thus preventing injury from high temperatures and smoke. The handle 3 is designed to make it easy for rescuers to open and close the protective door 2, and to facilitate the operation and maintenance of the rescue equipment inside.
