Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] Example: The fireproof safety cabin in the preferred embodiment of this utility model is as follows: Figures 1-6 As shown, the safety cabin includes a cabin body 1. A heat radiation reflective layer 104 is provided on the outer wall of the cabin body 1, and a heat insulation layer 105 is provided on the inner wall of the cabin body 1. A water chamber 103 is provided in the cabin body 1, which can contain cooling water to form a water-cooled layer between the outer wall and the inner wall of the cabin body 1. Thus, the entire cabin body 1 forms a three-layer heat insulation structure of heat radiation reflective layer 104, water-cooled layer and heat insulation layer 105, so as to effectively isolate the influence of external heat sources on the internal environment of the cabin body 1.

[0025] Specifically, the cabin 1 is provided with a water supply port and a drain port, which are connected to the water chamber 103 respectively. A water supply pipe 2 and a drain pipe 3 are provided corresponding to the water chamber 103. One end of the water supply pipe 2 is the water supply end 202, which is connected to the water supply port of the cabin 1. The other end is the inlet end 201, which is used to connect to cooling water, so that the cooling water can enter the water chamber 103 from the inlet end 201. One end of the drain pipe 3 is the water inlet end, and the other end is the drain end 301, which is used to discharge the cooling water in the water chamber 103. A pump body is provided corresponding to the water supply pipe 2 to pump the cooling water into the water chamber 103. The cooling water exchanges heat with the cabin 1 to cool the cabin 1, thereby achieving the isolation of the temperature inside and outside the cabin 1. Furthermore, the cooling water is flowing water. During emergency use, it is continuously supplied through the water supply pipe 2, and the drain pipe 3 also discharges the cooling water that has completed heat exchange, thereby improving the heat exchange efficiency.

[0026] Furthermore, the thickness of the heat radiation reflective layer 104 is 2-3 mm. The heat radiation reflective layer 104 is made of inorganic silicate, aluminum silicate fiber, heat reflective material, and hollow ceramic microspheres. The hollow ceramic microspheres are preferably hollow β-phase alumina ceramic microspheres. The thickness of the heat insulation layer 105 is 20 mm, and the material of the heat insulation layer 105 is aerogel insulation cotton. The heat radiation reflective layer 104 is used for heat radiation reflection to isolate external heat sources. The heat passing through the heat radiation reflective layer 104 is transferred to the cabin 1. The water-cooling layer exchanges heat with the cabin 1, thereby carrying away the heat from the cabin 1 to maintain the temperature stability of the cabin 1 structure. The heat insulation layer 105, located on the inner wall of the cabin 1, can also be a heat-absorbing layer to absorb and isolate the heat passing through the cabin 1, preventing heat loss into the interior space of the cabin 1. More preferably, the material of the cabin 1 is aluminum alloy.

[0027] Furthermore, the water chamber 103 can be a water pipe, which can be multiple U-shaped pipes connected in series. The water pipe passes through each wall of the cabin 1, so that the water-cooled layer formed by the water pipe can cover the internal environment of the cabin 1, thereby forming a good three-layer fireproof and heat-insulating structure of heat radiation reflection layer 104, water-cooled layer and heat insulation layer 105.

[0028] Furthermore, the cabin 1 includes a first shell 101 and a second shell 102 disposed inside the first shell 101. A gap is left between the first shell 101 and the second shell 102 to form a water chamber 103 between the two shells. The water chamber 103 can cover the second shell 102, thereby forming a corresponding water-cooled layer between the first shell 101 and the second shell 102. More preferably, a connector 106 is provided between the first shell 101 and the second shell 102, so that the first shell 101 and the second shell 102 are connected as a whole, thereby ensuring the structural stability between the two shells.

[0029] In one embodiment, a plurality of connectors 106 are provided between the first housing 101 and the second housing 102. The connectors 106 are beam structures, with their two side walls connected to the first housing 101 and the second housing 102 respectively. The beams are arranged circumferentially at intervals along the outer peripheral wall of the second housing 102 (i.e., the wall of the second housing 102 near the first housing 101). Further, the beams can be annular structures, fitted onto the outer peripheral wall of the second housing 102, and are arranged vertically at intervals. In this case, the beams divide the water chamber 103 into multiple spaces, and correspondingly, connecting holes are provided on the beams to ensure communication between the spaces.

[0030] In another embodiment, the second housing 102 is tightly fitted to the first housing 101, meaning the bottom of the first housing 101 abuts against the bottom of the second housing 102, and the inner wall of the first housing 101 and the outer wall of the second housing 102 are in contact. This allows the two housings to be fixedly connected via a bottom structure. Alternatively, the bottom plate of the second housing 102 can be the same as the bottom plate of the first housing 101. Furthermore, while the second housing 102 and the first housing 101 are fixedly connected via a bottom structure, connecting members 106 are still needed to maintain structural stability. Correspondingly, multiple connecting members 106 are provided on the top of the second housing 102, spaced apart along the length of the second housing 102.

[0031] Furthermore, a first through hole is provided on the cabin 1 for installing a door, so that the first housing 101 and the second housing 102 also have corresponding through holes, and a pipe is provided between the first housing 101 and the second housing 102, with the pipe connected to the two through holes respectively, so that the water chamber 103 formed between them remains sealed. Correspondingly, the pump body is located inside the cabin 1, so that multiple opposing through holes are provided between the first housing 101 and the second housing 102, through which the water supply pipe 2 and the drain pipe 3 pass. Similarly, a pipe is provided for each of the two opposing through holes to seal the water chamber 103.

[0032] Furthermore, a frame 5 is provided on the inner wall of the second shell 102. The frame 5 includes a plurality of annular supports spaced apart along the width direction. The annular supports are respectively connected to the top surface, bottom surface and two sides of the second shell 102. Reinforcing ribs are provided between each annular support to form a frame structure for supporting the entire cabin 1.

[0033] Furthermore, at least one support base 6 is provided at the bottom of the cabin 1. At least one second through hole and one third through hole are respectively provided in the first shell 101 and the second shell 102. The number of second through holes and third through holes corresponds one-to-one with the number of support bases 6, and the second through holes and third through holes are aligned so that one end of the support base 6 can pass through the two through holes. The support base 6 is fixedly connected to the frame 5 structure, and the end of the support base 6 away from the cabin 1 abuts against the ground. More preferably, a support beam is provided between each support base 6 to realize the fixed connection between each support base 6, and the support beam is fixedly connected to the frame 5 to enhance the connection strength between the support base 6 and the frame 5. Correspondingly, a traveling wheel 7 is provided at the bottom of the support base 6 to form a traveling mechanism, thereby facilitating the movement of the safety cabin.

[0034] Furthermore, the water supply inlet is located near the bottom of hull 1, and correspondingly, such as Figure 5 As shown, the drain outlet is located near the top of the cabin 1, and the water supply outlet and drain outlet are located on the second shell 102. Correspondingly, the drain end 301 of the drain pipe 3, the inlet end 201 and the water supply end 202 of the water supply pipe 2, and the first pump 203 corresponding to the water supply pipe 2 are all located at the bottom of the cabin 1, so that the water supply pipe 2 continuously supplies water to the bottom of the water chamber 103, causing the water level in the water chamber 103 to gradually rise until the water chamber 103 is filled. The inlet end of the drain pipe 3 is higher than the outer peripheral wall of the second shell 102 by a certain distance, so that the water level in the water chamber 103 will overflow into the inlet end of the drain pipe 3 after it is higher than the top end of the second shell 102, and then be discharged from the drain end 301 along the drain pipe 3, thereby ensuring that the cooling water fills the water chamber 103. More preferably, a pressure relief valve 107 is provided on the outer wall of the cabin 1. The pressure relief valve 107 is connected to the water chamber 103 to balance the pressure inside the water chamber 103, so as to cope with the pressure change inside the water chamber 103 caused by the rise in cooling water temperature. Preferably, the pressure relief valve 107 is located at the top of the cabin 1.

[0035] Furthermore, the drain pipe 3 extends from the bottom of the compartment to the top of the compartment. A constraint member is provided between the drain pipe 3 and the compartment 1. One end of the constraint member is fixedly connected to the compartment 1, and the other end is securely connected to the drain pipe 3. Multiple constraint members are spaced apart along the axial direction of the drain pipe 3. More preferably, the constraint member is a snap-fit ​​structure to securely fasten the drain pipe 3 to the inner wall of the compartment 1. Additionally, a groove is provided on the vertical structure of the frame 5 to embed the drain pipe 3, thereby fixing the drain pipe 3.

[0036] Furthermore, the fire-resistant safety cabin also includes at least one sprinkler head 4, which is disposed on the outer wall of the cabin 1 and connected to a water supply pipe 2. A second pump 204 is provided between the water supply end 202 of the water supply pipe 2 and the sprinkler head 4 to control the water supply of the sprinkler pipeline. More preferably, the sprinkler head 4 is disposed on the top of the cabin 1 to spray the outer wall of the cabin 1, thereby protecting the outer perimeter of the cabin 1 through heat absorption by water evaporation.

[0037] Furthermore, the fire-resistant safety compartment also includes a storage tank. The inlet end 201 of the water supply pipe 2 is connected to the storage tank for water supply. The storage tank is equipped with a water inlet pipe to receive external water supply, allowing cooling water to be supplied through the storage tank when external water supply to the cooling system is unavailable. More preferably, the drain end 301 of the drain pipe 3 is also connected to the storage tank, allowing the water discharged from the drain pipe 3 to flow back into the storage tank, thus ensuring the water supply for the entire cooling system. This enables the circulation of cooling water in the absence of external water supply, ensuring sufficient water in the water chamber 103 for heat exchange. Further explanation: when switching to water supply from the storage tank, the second pump 204 no longer pumps water from the water supply pipe 2 into the spray head 4, prioritizing the cooling water supply to the water chamber 103.

[0038] Furthermore, a smoke sensor and / or temperature sensor are installed outside the cabin 1, and a corresponding control module is installed inside the cabin 1. When the smoke sensor and / or temperature sensor detects the presence of smoke or an increase in indoor temperature, the first pump 203 and the storage tank water pump are immediately started to fill the cooling water in the water chamber 103 and the storage tank in advance.

[0039] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
