There are many traditional cable wall sealing methods, but they usually have the following problems:

[0003] Poor fire resistance: When ordinary rubber is used as a sealing module, it will be ignited in the event of a fire, and the flames and smoke will spread to other areas through the perforations, causing the fire to spread.

[0004] Poor sealing effect: Traditional sealing methods often cannot fully adapt to the needs of cables of different diameters. The contact between the sealing material and the cable is not tight, resulting in unsatisfactory sealing effect and easy leakage.

[0005] Complex installation: The installation process of many traditional sealing devices is cumbersome, requiring more steps and time, and requires high skills of construction workers, which increases installation costs and time.

[0006] Poor adaptability: Traditional sealing devices can usually only seal cables of specific diameters. They lack modularity and flexibility and are difficult to meet the wall sealing needs of cables of different diameters.

[0007] Difficult maintenance: Once the cable needs to be replaced or maintained, traditional sealing devices usually require the removal of a large amount of sealing materials. The process is cumbersome and can easily damage the integrity of the sealing device, increasing maintenance costs and difficulty. Summary of the invention

[0008] The purpose of the utility model is to provide a modular wall-penetrating cable sealing device. Through innovative structural design, the problems of poor fire resistance, poor sealing effect, complex installation, poor adaptability and difficult maintenance existing in the traditional method are effectively solved.

[0009] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:

[0010] The utility model discloses a modular wall-penetrating cable sealing device, comprising a sealing frame, a rubber sealing module and a clamping device. The sealing frame is preset to be installed through the wall. There are multiple rubber sealing modules, and a semicircular groove matching the cable diameter is arranged in the middle of each rubber sealing module. Two rubber sealing modules are symmetrically arranged outside the cable. The two rubber sealing modules form a group of sealing members. After the cables are installed, multiple groups of sealing members are evenly placed in the lower section of the sealing frame, and the clamping device is arranged in the upper section of the sealing frame.

[0011] As an improvement, the inner layer of the rubber sealing module is provided with a multi-layer silicone sealing pad, and the multi-layer silicone sealing pad is fixedly arranged on the surface of the semicircular groove of the rubber sealing module.

[0012] The multiple rubber sealing modules include rubber sealing modules of different sizes, each of which is provided with a semicircular groove matching the cable diameter according to cables of different diameters, and multiple groups of sealing members of different sizes and the clamping device fill the sealing frame.

[0013] Specifically, the clamping device includes a clamping device panel, an iron outer shell, a clamping plate, a nut seat, a screw, a supporting connecting rod and an adjusting bolt. The iron outer shell is rectangular and is open at one end and both sides. The clamping device panel is fixedly arranged at the middle open end of the iron outer shell. The screw passes through the clamping device panel and is rotatably connected to the clamping device panel. One end of the screw located outside the clamping device panel is fixedly connected to the adjusting bolt, and a section of the screw located inside the clamping device panel is threadedly connected to the nut seat.

[0015] The beneficial effects of the utility model are:

[0016] The utility model is a modular wall-penetrating cable sealing device. Compared with the prior art, the utility model has the following technical effects:

[0017] Improve fire resistance: The utility model uses vitrified rubber as a sealing module, which can form a hard ceramic body when exposed to fire, thereby ensuring the structural integrity under fire conditions, improving the fire resistance of the structure, and preventing the spread of flames and smoke.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0031] like Figure 1 As shown: the utility model is a modular wall-penetrating cable sealing device comprising a sealing frame 2, a rubber sealing module 3 and a clamping device. The sealing frame 2 is preset to be installed through the wall 1. There are multiple rubber sealing modules 3. The middle part of each rubber sealing module 3 is provided with a semicircular groove matching the diameter of the cable 5. Two rubber sealing modules 3 are symmetrically arranged outside the cable 5. The two rubber sealing modules 3 form a group of seals. After the cables 5 are installed, the multiple groups of seals are evenly placed in the lower section of the sealing frame 2. The clamping device is arranged in the upper section of the sealing frame 2.

[0032] As an improvement, the inner layer of the rubber sealing module 3 is provided with a multi-layer silicone sealing pad 4 , and the multi-layer silicone sealing pad 4 is fixedly arranged on the surface of the semicircular groove of the rubber sealing module 3 .

[0033] The multiple rubber sealing modules 3 include rubber sealing modules 3 of different sizes, each of which is provided with a semicircular groove matching the diameter of the cable 5 according to the different diameters of the cable 5 , and multiple groups of seals of different sizes and the clamping device fill the sealing frame 2 .

[0034] Specifically, the clamping device includes a clamping device panel 6, an iron outer shell 7, a clamping plate 8, a nut seat 9, a screw 10, a support connecting rod 11 and an adjusting bolt 12. The iron outer shell 7 is rectangular and is open at one end and both sides. The clamping device panel 6 is fixedly arranged at the middle open end of the iron outer shell 7. The screw 10 passes through the clamping device panel 6, and the screw 10 is rotatably connected to the clamping device panel 6. One end of the screw 10 located outside the clamping device panel 6 is fixedly connected to the adjusting bolt 12, and a section of the screw 10 located inside the clamping device panel 6 is threadedly connected to the nut seat 9. The upper and lower sides of the nut seat 9 are respectively rotatably connected to one end of the two supporting connecting rods 11. The clamping plate 8 consists of two pieces. The two clamping plates 8 are respectively fixedly arranged on the upper and lower surfaces of the iron outer shell 7, and the other ends of the two supporting connecting rods 11 are respectively rotatably connected to the middle parts of the two clamping plates 8.

[0035] As an improvement, the rubber sealing module 3 is made of a ceramic silicone rubber material, which can form a hard ceramic body when exposed to fire, thereby ensuring the structural integrity under fire conditions, improving the fire resistance, and preventing the spread of flames and smoke.

[0036] The working principle of the utility model is as follows:

[0037] When the utility model is used, the corresponding multi-layer silicone sealing pad 4 is selected according to the diameter of the cable 5 that needs to pass through the wall, and the two rubber sealing modules 3 are combined on the outside of the cable 5. The multi-layer silicone sealing pad 4 can be a flexible silicone with viscosity to increase the sealing between the rubber sealing module 3 and the cable 5. The rubber sealing module 3 is an elastic material with a certain hardness. Multiple groups of the rubber sealing modules 3 need to be filled in the sealing frame 2 together with the pressing device. When the cable 5 is connected to the rubber sealing module 3, it is placed in the sealing frame 2, and finally the multiple rubber sealing modules 3 are pressed by the pressing device. The sealing installation of the wall-penetrating cable can be completed. The clamping device drives the screw 10 to rotate by adjusting the adjusting bolt 12. The screw 10 rotates relative to the clamping device panel 6. The nut seat 9 and the screw 10 are threadedly connected. Therefore, the nut seat 9 can move on the screw 10, thereby pushing the two supporting connecting rods 11 to lift the two clamping plates 8 through the nut seat 9. The iron sheet outer shell 7 is usually a thinner iron sheet, so it can be deformed. The supporting connecting rod 11 pushes the clamping plate 8 to lift the iron sheet outer shell 7, thereby compressing multiple rubber sealing modules 3 to complete the wall-penetrating sealing of the cable.
