Detailed Implementation

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a high-strength impact-resistant modified polyvinyl chloride composite material structural wall power sheath tube, including a sheath tube body 1, a polyvinyl chloride layer 2 bonded to the outside of the sheath tube body 1, a support structure 3 provided on the inside of the sheath tube body 1, and a partition structure 4 provided on the surface of the cylindrical frame 36.

[0029] The specific setup and function of its support structure 3 and partition structure 4 will be discussed below.

[0030] Reference Figures 1-3As shown in this embodiment: the support structure 3 includes a support plate 31 located inside the sheath tube body 1. Three supports are provided on the support plate 31, and pre-drilled grooves 32 are formed on the surface of the supports. An L-shaped sliding rod 33 is slidably connected to the inner side of the pre-drilled grooves 32. A screw 38 is rotatably connected inside the support plate 31. A cylindrical frame 36 is slidably connected to the side wall of the support plate 31, and three diagonal strips 37 are fixedly connected to the side wall of the cylindrical frame 36. The screw 38 and the cylindrical frame 36 are internally threaded. By setting up the support structure 3, flexible support for the port position of the sheath tube body 1 is facilitated, preventing bending and breakage when the port position of the sheath tube body 1 is subjected to external pressure or impact, thereby improving the pressure and impact resistance of the port position of the sheath tube body 1. An arc-shaped plate 34 is fixedly connected to the end of the sliding rod 33. The arc-shaped plate 34 can tightly fit the internal cable, providing support for the cable, distributing external pressure, and preventing damage to the cable due to excessive local pressure. A protective pad 35 is glued to the surface of the curved plate 34. The protective pad 35 prevents direct hard contact between the curved plate 34 and the cable, thus preventing scratches to the cable sheath during support. Elastic rings 39 are slidably connected inside the three sliding rods 33. Rotating the screw 38 in the opposite direction causes the three sliding rods 33 to move towards each other due to the elastic force of the elastic rings 39.

[0031] Reference Figures 1-4 As shown, specifically, the partition structure 4 includes a connecting pin 45 fixedly connected to the surface of the cylindrical frame 36, and several partition strips 41 are rotatably connected to the side wall of the connecting pin 45. By setting up the partition structure 4, the flexible partitioning of cables inside the sheath body 1 is facilitated. After the cables are partitioned, the position and direction of each cable are clearly defined, allowing maintenance personnel to quickly locate the faulty cable without having to search through numerous cables, significantly shortening the time for fault diagnosis and repair. A sliding strip 42 is slidably connected inside the partition strip 41. The sliding strip 42 fits against the inner wall of the sheath body 1, thereby improving the efficiency of partitioning the cable lines. A fixing block 43 is fixedly connected to the surface of the partition strip 41, and an elastic pad 44 is glued to the surface of the fixing block 43 near the sliding strip 42. By setting the elastic pad 44, the resistance to pulling the sliding strip 42 inside the partition strip 41 is increased, thereby improving the stability of using the sliding strip 42 after it is pulled out.

[0032] Working principle: The polyvinyl chloride (PVC) layer 2 bonded to the outside of the sheath tube body 1 has good toughness and corrosion resistance. When the sheath tube end is subjected to external impact, the PVC layer 2 can absorb part of the impact force and resist corrosive substances in the soil, preventing the sheath tube body 1 from being eroded and extending the service life of the sheath tube. When the sheath tube is subjected to external pressure, the support structure 3 begins to play a key role. If it is necessary to adjust the support state of the support structure 3, rotate the screw 38. Since the screw 38 is connected to the internal thread of the cylindrical frame 36, the rotation of the screw 38 will be converted into the linear movement of the cylindrical frame 36 along the side wall of the support plate 31. The inclined strip 37 on the side wall of the cylindrical frame 36 will move with the cylindrical frame 36, pushing the slide rod 33 to slide in the reserved groove 32. The arc-shaped plate 34 fixed at one end of the slide rod 33 will move closer to or away from the center of the sheath tube accordingly. When the sheath is subjected to external pressure, the arc plate 34 can fit tightly against the internal cable, providing support for the cable, sharing the external pressure, and preventing the cable from being damaged due to excessive local pressure. Rotating the screw 38 in the opposite direction will cause the three sliding rods 33 to move towards each other under the elastic force of the elastic ring 39, facilitating the removal of the support structure 3 from the inside of the sheath body 1. The protective pad 35 glued to the surface of the arc plate 34 can prevent the arc plate 34 from making direct hard contact with the cable, preventing scratches on the cable sheath during the support process. By setting up the support structure 3, it is convenient to flexibly support the port position of the sheath body 1, avoiding bending and cracking when the port position of the sheath body 1 is subjected to external pressure or impact, thereby improving the pressure and impact resistance of the port position of the sheath body 1.

[0033] When separating different cable lines, the separating structure 4 plays a role. The connecting pin 45 is fixed to the surface of the cylindrical frame 36. The separating strip 41, which is rotatably connected to the side wall of the connecting pin 45, can rotate around the connecting pin 45. According to the cable laying requirements, the separating strip 41 can be rotated to a suitable angle to achieve the initial separation of different cable lines. The sliding strip 42 is slidably connected inside the separating strip 41. The sliding strip 42 can fit against the inner wall of the sheath body 1, thereby improving the efficiency of separating cable lines. By setting the elastic pad 44, the resistance of pulling the sliding strip 42 inside the separating strip 41 is increased, thereby improving the stability of the sliding strip 42 after it is pulled out. By setting the separating structure 4, the flexible separation of cables inside the sheath body 1 is facilitated. After the cables are separated, the position and direction of each cable are clear, and maintenance personnel can quickly locate the faulty cable without having to search among many cables, which greatly shortens the fault diagnosis and repair time.
