[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 In this embodiment, a prefabricated power channel includes an assembly box 1 and channel pipes 2 installed on both sides of the assembly box 1. A partition baffle 3 is fixedly installed on the inner side of the assembly box 1, and fixed slide rails 4 are installed at both the front and rear ends of the inner side of the assembly box 1. A bracket assembly is slidably installed on the surface of the fixed slide rail 4. A maintenance cover 5 is installed on the top of the assembly box 1. The channel pipes 2 are arranged in an array, and a sealing connector is provided at the end of the channel pipe 2. The sealing connector is used for the connection between the channel pipes 2.

[0026] In this embodiment, the channel tube 2 has pipe holes that extend through the channel tube 2 from left to right and are distributed in a rectangular array.

[0027] It should be noted that: the channel pipe 2 is assembled, while the assembly box 1 is a maintenance port. Therefore, the assembly box 1 is larger in size, and the top maintenance cover 5 can be opened for inspection. The cable connection joints are all located in the assembly box 1, while the channel pipe 2 is connected by sealing connectors to increase the sealing of the connection and facilitate pre-embedded installation.

[0028] Please see Figure 1 and Figure 3In this embodiment, the surface of the assembly box 1 is provided with a connection port for assembling the channel pipe 2. The maintenance top cover 5 and the top of the assembly box 1 are detachably connected. The partition baffle 3 is a plate made of fire-retardant material, and the partition baffle 3 divides the interior of the assembly box 1 into two chambers.

[0029] In this embodiment, the partition 3 is an inorganic fireproof partition, which is made of a variety of non-combustible materials through scientific blending and pressing. It has the characteristics of good flame retardant performance and non-combustibility when exposed to fire. Its combustion performance meets the non-combustible A1 (Class A) standard specified in GB8624-2012. It can effectively prevent the spread of flames between the two chambers in the assembly box 1, and the structure of the two chambers increases fire safety.

[0030] Please see Figure 3 and Figure 4 In this embodiment, the fixed slide rails 4 are evenly spaced, and the surface of the fixed slide rails 4 is provided with a plurality of limiting holes 41 for limiting and fixing. The limiting holes 41 are evenly spaced from top to bottom. The bracket assembly includes a sliding seat 42, which is slidably connected to the surface of the fixed slide rails 4. A support plate 43 is fixedly connected to the surface of the sliding seat 42. The support plate 43 is used to support the cable. There are three sliding seats 42. The surface of the sliding seat 42 is located below the support plate 43 and a locking bolt 44 is threadedly installed. The locking bolt 44 is threadedly connected to the limiting holes 41. When the locking bolt 44 is inserted into the limiting hole 41, the sliding seat 42 is fixed to the surface of the fixed slide rail 4.

[0031] In this embodiment, the support plate 43 is used to support the cable, thereby separating different cables by placing them in different positions. The fixed slide rail 4 is installed inside the assembly box 1 by bolts. The limiting hole 41 on its surface cooperates with the locking bolt 44 at the bottom of the sliding seat 42 to achieve precise positioning and stable fixation of the sliding seat 42 on the slide rail, preventing the sliding seat 42 from shifting due to vibration or impact, and ensuring stable support of the cable by the support plate 43. At the same time, the sliding connection design between the sliding seat 42 and the fixed slide rail 4 makes it easy to adjust the position of the support plate 43 according to the cable laying requirements, improving installation flexibility and facilitating the inspection and adjustment of the cable during later maintenance.

[0032] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, the sealing connector includes a connecting seat 21. The side of the surface of the connecting seat 21 is provided with a connecting hole for connection. The connecting seat 21 is fixedly connected to the end of the channel tube 2 through a connecting piece 22. The connecting piece 22 has a double-layer structure, and a rubber filling layer is provided between the two connecting pieces 22. The thickness of the connecting piece 22 is less than 1cm.

[0033] It should be noted that the connecting piece 22 of the sealing connector adopts a double-layer structure and has a built-in rubber filling layer. The rubber material has elastic deformation characteristics, which can absorb the displacement caused by uneven settlement of the foundation and avoid rigid tearing at the splicing part of the channel pipe 2. The connecting piece 22 is a thin metal sheet structure with deformation capability, which also enhances the sealing performance of the connection and effectively prevents water vapor, dust and flames from entering through the connection gap. Combined with the tight connection between the connecting seat 21 and the connecting hole, the stability and safety of the connection between the channel pipes 2 are further improved.

[0034] The working principle of the above embodiments is as follows:

[0035] During installation, the mounting surfaces of assembly box 1 and channel pipe 2 need to be prepared in advance. Assembly box 1 is placed and installed first, and then channel pipe 2 is installed on both sides of it so that the internal channel holes are connected to assembly box 1. Then, other channel pipe 2 are assembled and spliced ​​on channel pipe 2 and fastened through connecting seat 21. The connecting piece 22 is a thin metal sheet that fits the rubber layer to achieve elastic connection between channel pipe 2. During settlement, it absorbs the displacement caused by uneven settlement of the foundation and avoids rigid tearing or bending deformation at the splicing part of channel pipe 2. At the same time, it can allow a certain installation error, simplify the on-site assembly process, and facilitate construction. The cable pipe joint enters the assembly box 1 and is separated into two chambers by the partition baffle 3, which facilitates the separation and placement of the cable joint. The cable is supported by the support plate 43, and different cables are erected in different positions to achieve separation. The sliding connection of sliding seat 42 and fixed slide rail 4 makes it easy to adjust the position of support plate 43, which improves flexibility.
