[0043] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0044] Figures 1-2 FIG. 1 shows a structural diagram of a cable fire-proof pipe opening sealing device 100 according to an embodiment of the present application. Figures 1-2 As shown, the blocking device 100 may include:

[0045] A protective assembly 110, which is arranged on the cable and supports the fireproof tube when the cable is arranged in the fireproof tube;

[0046] a bottom plate 120 , the bottom plate 120 being detachably disposed on the protection assembly 110 , and the cable passing through the bottom plate 120 ;

[0047] The plug assembly 130 is arranged on the base plate 120, and the fireproof pipe opening is sealed by the plug assembly 130.

[0048] In this embodiment, the protection component 110 is fixed to the cable in advance, and the bottom plate 120 is installed on the protection component 110. When the cable is placed in the fireproof pipe, the protection component 110 is located below the fireproof pipe opening. Due to the setting of the protection component 110, when the cable is placed in the fireproof pipe, the protection component 110 fits against the inner wall of the fireproof pipe, thereby limiting the position of the cable in the fireproof pipe and preventing the cable from swinging and rubbing in the fireproof pipe, which may cause damage to the cable. After placement, the plug component 130 is filled onto the bottom plate 120 to fill the space between the fireproof pipe opening and the cable to ensure the sealing of the joint between the fireproof pipe and the cable and protect the interface.

[0049] Through the setting of the protection component 110, when the cable is placed in the fireproof pipe, the protection component 110 fits against the inner wall of the fireproof pipe, thereby limiting the position of the cable in the fireproof pipe, preventing the cable from swinging and rubbing in the fireproof pipe, causing the plug component 130 to loosen and resulting in sand leakage. Through the setting of the base plate 120, the plug component 130 is filled on the base plate 120 to fill the space between the fireproof pipe opening and the cable to ensure the sealing of the joint between the fireproof pipe and the cable and protect the interface.

[0050] like Figures 1-2 As shown, in one embodiment,

[0051] The protection component 110 includes:

[0052] A casing 111 is provided on the cable. When the cable is placed in a fireproof tube, the casing 111 is located in the fireproof tube.

[0053] At least two support plates 112, at least two of the support plates 112 are arranged on the casing 111, and the support plates 112 are in contact with the inner wall of the fireproof pipe;

[0054] The supporting components 113 are matched in number with the supporting plates 112 . The supporting components 113 are arranged between the housing 111 and the supporting plates 112 . The supporting components 113 support the supporting plates 112 so that the supporting plates 112 protect the cables.

[0055] In this embodiment, when the casing 111 and the support plate 112 are placed in the fireproof tube, the support plate 112 is fitted against the inner wall of the fireproof tube under the action of the support assembly 113. When the cable is subjected to squeezing or twisting force, the cable moves relative to the position of the fireproof tube, and the support assembly 113 is deformed. When the force stops, the support assembly 113 is reset, thereby restoring the position of the cable relative to the protective tube.

[0056] like Figure 2 As shown, in one embodiment,

[0057] The support assembly 113 includes:

[0058] A support rod 1131, one end of which is rotatably mounted on the support plate 112;

[0059] a slider 1132 rotatably disposed on an end of the support rod 1131 away from the support plate 112 ;

[0060] The fixing rod 1133 is provided on the housing 111 , and the slider 1132 is slidably provided on the fixing rod 1133 .

[0061] Spring 1134, the spring 1134 is sleeved on the fixing rod 1133, the sleeve 111 is provided with a groove 1135 adapted to the fixing rod 1133, the spring 1134 is located in the groove 1135, one end of the spring 1134 is connected to the sleeve 111, and the other end is connected to the slider 1132.

[0062] In this embodiment, when the support plate 112 is subjected to force, the support rod 1131 rotates, thereby driving the slider 1132 to move along the fixed rod 1133, thereby causing the spring 1134 to deform. When the force applied to the support plate 112 disappears, the spring 1134 resets, causing the slider 1132 to push the support rod 1131 to reset, thereby resetting the support plate 112.

[0063] like Figure 2 As shown, in one embodiment,

[0064] The bottom plate 120 has a T-shaped cross section.

[0068] The bottom plate 120 is threadedly connected to the threaded block on the casing 111 through threads;

[0069] The diameter of the bottom plate 120 matches the inner diameter of the fireproof pipe to prevent the fireproof blocking material 131 from leaking into the fireproof pipe.

[0070] like Figure 2 As shown, in one embodiment,

[0071] The bottom plate 120 is provided with a through hole for the cable to pass through, and the size of the through hole is adapted to the size of the cable.

[0072] In this embodiment, the through hole facilitates the passage of the cable through the bottom plate 120 , and the size of the through hole matches the size of the cable to prevent the fireproof component from falling into the fireproof tube through the through hole.

[0073] like Figure 2 As shown, in one embodiment,

[0074] The plug assembly 130 is disposed on the base plate 120 .

[0075] The plug assembly 130 is a fireproof plugging material 131.

[0076] In this embodiment, the fireproof component is a fireproof plugging material 131, which is arranged between the bottom plate 120 and the fireproof pipe opening. When the bottom plate 120 is installed in the fireproof pipe, the fireproof plugging material 131 is filled into the fireproof pipe and compacted by an external device.

[0077] After the treatment is completed, apply fire retardant coating on the surface of the fireproof pipe and the fireproof blocking material 131 with a thickness of not less than 1mm;

[0078] Furthermore, the fireproof blocking material 131 is an organic fireproof blocking material 131 .

[0079] like Figures 1-2 As shown, in one embodiment,

[0080] The thickness of the fireproof blocking material 131 is greater than or equal to 30 mm.

[0081] In this embodiment, the thickness of the fireproof blocking material 131 is greater than or equal to 30 mm, thereby ensuring the sealing of the fireproof pipe opening and thus ensuring the safety of the fireproof pipe opening.
