[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multifunctional electric power construction electric power fire protection device of the utility model comprises a cable duct 1, inner tubes 8 are threadedly connected to the openings at both ends of the cable duct 1, opposite ends of the inner tubes 8 extend to the outside, and connecting flanges 2 are installed, panels are movably installed inside the connecting flanges 2, assembly grooves are provided on the outer surfaces of the panels, a plurality of wiring holes 9 connected to the cable duct 1 are provided on the inner wall surfaces of the assembly grooves, panels 4 are provided in the assembly grooves, through holes are provided at the panels 4 facing the wiring holes 9, sealing sleeves 5 are installed inside the through holes, and one end of the sealing sleeves 5 is inserted into the wiring holes 9.

[0023] In this embodiment, the openings at both ends of the cable duct 1 are equipped with limit rings 6, and the outer end faces of the limit rings 6 are set in contact with the end faces of the inner tube 8. The inner tube 8 is provided with a first sealing groove of an annular structure on one end face away from the connecting flange 2, and a first sealing ring is provided in the first sealing groove, and one side face of the first sealing ring is set in contact with the limit ring 6;

[0024] Among them, after the inner tube is threadedly connected in the cable pipe, one end of the inner tube can contact the first sealing ring, thereby increasing the sealing performance between the inner tube and the cable pipe.

[0025] In this embodiment, a second sealing groove with an annular structure is provided on the outer side surface of the connecting flange 2, and a second sealing ring 3 is provided in the second sealing groove; wherein the first sealing ring and the second sealing ring are both made of rubber material, and after the adjacent cable pipes are connected, the second sealing rings on the connecting flanges can be pressed together, thereby improving the sealing between the connecting flanges.

[0026] In this embodiment, a positioning ring 7 is installed on the outer ring surface of the panel 4, and a positioning groove of an annular structure is provided on the inner ring surface of the connecting flange 2. The positioning ring 7 is movably arranged in the positioning groove so that the panel can only rotate along the positioning groove, and the rotation of the connecting flange will not drive the panel.

[0027] In this embodiment, the outer side surface of the panel 4 is flush with the outer side surface of the connecting flange 2; wherein, when adjacent cable ducts are connected, the panels can be pressed together; conversely, after the adjacent cable ducts are disassembled, the panel can be directly taken outwards, and the movement of the panel drives the sealing sleeve, making it convenient to replace the sealing sleeve.

[0028] In this embodiment, the sealing sleeves 5 are all made of rubber material. The sealing sleeves made of rubber material can seal the gap between the cable and the wiring hole, thereby improving the sealing effect.

[0029] In this embodiment, a flame retardant layer is installed on the inner wall surface of the cable duct 1. The flame retardant layer can be asbestos, which has a very significant flame retardant effect. Asbestos is highly fire resistant, with a melting point as high as 1500°C, and can be used for a long time in a high temperature environment without melting or burning. In addition, asbestos has a low thermal conductivity, which helps to effectively prevent the transfer of heat and further reduce the risk of fire.

[0030] When in use, first disassemble the connecting flanges on both sides, so that the cable can pass through the sealing sleeve and the wiring hole on one side to extend into the cable duct, until it passes through the sealing sleeve and the wiring hole on the other side. After the cable passes through, the connecting flange can be held, and the inner pipe thread can be connected to the openings at both ends of the cable duct. During the rotation process, due to the movable connection between the panel and the connecting flange, the rotation of the connecting flange will not drive the rotation of the panel, thereby avoiding the twisting of the cable; wherein, the two ends of the cable duct can be sealed by the connecting flange, the panel and the connecting pipe, and the cables can be independently separated and set through the wiring hole, and the cables need to be tightened to avoid contact between the cables due to sagging, and to avoid interlacing and overlapping of the cables. After tightening, it can be positioned by the friction between the sealing sleeve;

[0031] Among them, after the cable duct is sealed, it can effectively prevent the spread of fire, and the cable and the sealing sleeve are in complete contact, thereby sealing the risk between the cable and the sealing sleeve, avoiding contact with external air, and preventing air from entering the cable duct, further preventing the spread of fire, and greatly increasing safety.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
