[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] Please refer to Figures 1-5 The utility model provides a technical scheme that:

[0022] Referring to Figures 1-5 As shown in the drawings, a variable diameter fireproof sealing module comprises a body 1 comprising at least an outer protective layer, an expansion lining and a bottom layer, which are combined, wrapped and bonded together to form a sealed cavity, and the body 1 is provided with an air inlet pipe 2 and an air outlet pipe 9 respectively on opposite sides and in communication with the cavity.

[0023] A one-way valve is arranged on the air inlet pipe 2 and the air outlet pipe 9, and the conduction direction is from the air inlet pipe 2 to the air outlet pipe 9.

[0024] When a fire occurs, a large amount of smoke and toxic gas will be generated, and the temperature of the surrounding environment will rise. The high temperature is transmitted to the corrugated pipe 3, and the expansion graphite 6 in the corrugated pipe 3 expands rapidly when it encounters high temperature. Due to the restriction of the corrugated pipe 3 and the air inlet pipe 2, the expansion graphite 6 can only expand and extend in the direction of the first one-way valve 7. The corrugated pipe 3 pushes open the first one-way valve 7, and the smoke enters the air inlet pipe 2, passes through the telescopic pipe 5, and then flows into the body 1 from the distance between the first one-way valve 7 and the air inlet pipe 2. The smoke and fog themselves have temperature, and when they enter the body 1, they will undergo heat transfer with the air in the body 1. Due to the effects of heat conduction and heat convection, heat will be transferred from the high-temperature smoke and fog to the air in the body 1, causing the air temperature to rise. The air expands when heated, and then the body 1 expands towards the cable, making the body 1 fit the cable more tightly. At the same time, it can adapt to different sizes of gaps. When the pressure inside the body 1 is too high and the temperature is too high, the second one-way valve 10 can be used for pressure relief. The above can greatly increase the effect of fireproof separation

[0025] Referring to Figures 1-4 The one-way valves arranged on the air inlet pipe 2 and the air outlet pipe 9 are the first one-way valve 7 and the second one-way valve 10, and the conduction pressure of the first one-way valve 7 is less than that of the second one-way valve 10.

[0026] When the internal pressure of the module rises to a certain degree, the second one-way valve 10 on the air outlet pipe 9 will open to allow gas to be discharged. This can effectively control the flow direction of the gas and prevent backflow, ensuring the normal operation of the module. For example, when a fire occurs, the internal pressure of the module may increase due to the rise in temperature. If there is no control of the one-way valve, the gas may flow disorderly, affecting the fireproof sealing effect of the module.

[0027] Referring to Figure 2 Two installation plates 4 are arranged in the air inlet pipe 2, and the installation plates 4 are arranged in parallel. The installation plate 4 close to the first one-way valve 7 is slidingly arranged, and the installation plate 4 away from the first one-way valve 7 is provided with a gas inlet hole penetrating through. The corrugated pipe 3 is arranged between the two installation plates 4, and the inside of the corrugated pipe 3 is filled with expansion graphite 6.

[0028] The mounting plate 4 away from the first one-way valve 7 can be fixed on the air inlet pipe 2, and the other mounting plate 4 is driven to extend by the expanded graphite 6, which can better open the first one-way valve 7.

[0029] The corrugated pipe 3 is installed between the two mounting plates 4 and filled with the expanded graphite 6 inside. When a fire occurs, the expanded graphite 6 expands rapidly due to high temperature. Due to the restriction of the corrugated pipe 3 and the air inlet pipe 2, the expanded graphite 6 can only expand and extend in the direction of the first one-way valve 7, thereby opening the first one-way valve 7 and allowing smoke to enter the body 1, thereby enhancing the fire separation effect. At the same time, the corrugated pipe 3 can provide a certain guidance and constraint for the expansion of the expanded graphite 6, ensuring the stability and reliability of the expansion process.

[0030] Referring to Figure 2 , a plurality of telescopic pipes 5 extending in the axial direction are arranged in the corrugated pipe 3, and the two ends thereof are arranged to penetrate the side wall of the mounting plate 4.

[0031] The telescopic pipe 5 can guide the expansion direction of the expanded graphite 6 to a certain extent. When the expanded graphite 6 expands due to heat, the telescopic pipe 5 can limit its expansion in the axial direction, ensuring that the expansion force is mainly in the direction of the first one-way valve 7, thereby more effectively opening the first one-way valve 7 and allowing smoke to smoothly enter the body 1, thereby enhancing the fire separation effect.

[0032] Referring to Figure 2 , the telescopic pipe 5 includes a sleeve and a spigot, the spigot is sealingly and slidingly inserted into the sleeve, and the spigot and the sleeve penetrate the opposite mounting plate 4 at one end.

[0033] This structure design makes the telescopic pipe 5 adjustable in length direction. When the expanded graphite 6 in the corrugated pipe 3 expands due to heat, the telescopic pipe 5 can be elongated accordingly with the expansion force, better adapting to the deformation of the corrugated pipe 3, providing enough space for the expansion of the expanded graphite 6, while ensuring that the smoke can smoothly pass through the telescopic pipe 5 into the body 1, thereby enhancing the fire separation effect.

[0034] Referring to Figures 2-3 , a plurality of fixing rods 8 are installed on the end face of the mounting plate 4 close to the first one-way valve 7, and vertically extend outward from the end face of the mounting plate 4.

[0035] Referring to Figure 5 , the body 1 is provided with a humidity sensor, the humidity sensor is connected to a detection device through a signal, and one side of the body 1 is provided with a humidifier.

[0036] The humidity sensor detects the humidity and transmits a signal to the detection device. After the detection device obtains that the humidity is lower than the set humidity, the alarm device sounds and the humidifier sprays to humidify.

[0037] Working principle: when the fire will produce a large amount of smoke and toxic gases, the temperature of the surrounding environment, the high temperature to the corrugated pipe 3, the expansion of graphite 6 in the corrugated tube 3 meet the high temperature rapidly expand, because the corrugated tube 3 and the air pipe 2 limit, with the expansion of graphite 6 can only be in the direction of the first one-way valve 7 expansion extension, the corrugated tube 3 will open the first one-way valve 7, smoke into the air pipe 2 through the telescopic tube 5, then from the first one-way valve 7 and the air pipe 2 between the distance into the body 1 inside, into the body 1 inside, the smoke and fog itself with temperature, when they enter the body 1, will with the air of body 1 heat transfer, due to heat conduction, heat convection and other effects, heat will be from the high temperature of smoke and fog to the air in the body 1, make the air temperature rise, air expansion, and then make the body 1 in the direction of the cable expansion, with the cable fit more closely, at the same time can adapt to different size gap, when the pressure in the body 1 is too large, the temperature is too high, can through the second one-way valve 10 pressure relief, the above can greatly increase the effect of fire separation.
