DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A corrosion-resistant CPVC cable protection tube comprises a base 1, a fixing plate 2 and a support frame 3. A protection structure for protecting the cable is arranged on the inner side of the center of the support frame 3.

[0024] like Figure 1 As shown, the protection structure includes a protection tube body 4 fixedly connected to the inner side of the center of the support frame 3, an elastic telescopic rod 5 respectively fixedly connected to the inner top wall and the inner bottom wall of the protection tube body 4, a waterproof casing 6 fixedly connected to one end of the piston rod of the elastic telescopic rod 5, and sponge pads 7 respectively fixedly connected to the opposite sides of the two waterproof casings 6.

[0025] It should be noted that the cross-section of the base 1 is an isosceles trapezoid as a whole, and three threaded tubes 8 are fixedly connected to the inner bottom wall of the base 1, and the inner sides of the three threaded tubes 8 are threadedly connected to threaded rods 9, and the tops of the three threaded rods 9 are fixedly connected to mounting grooves 10, and the inner sides of the three mounting grooves 10 are slidably connected to sliders 11, and the fixing plate 2 is fixedly connected between the upper surfaces of the three sliders 11, the bottom ends of the threaded rods 9 penetrate the upper surface of the base 1 and extend to the inner sides of the corresponding threaded tubes 8 and are threadedly connected to the corresponding threaded tubes 8, and two rubber blocks 12 are fixedly connected to the inner bottom wall of the base 1, and the rubber block 12 is located between the opposite sides of two adjacent threaded tubes 8.

[0026] A rubber sleeve 13 is fixedly connected to the outer side of the protection tube body 4, and two elastic telescopic rods 5 are fixedly connected to the inner top wall of the protection tube body 4, and two elastic telescopic rods 5 are fixedly connected to the inner bottom wall of the protection tube body 4. The upper waterproof casing 6 is fixedly connected between the bottom ends of the piston rods of the two upper elastic telescopic rods 5, and the lower waterproof casing 6 is fixedly connected between the top ends of the piston rods of the two lower elastic telescopic rods 5.

[0027] The two sponge pads 7 are respectively fixedly connected to the inner bottom wall and the inner bottom wall of the protection tube body 4, and the upper sponge pad 7 is located between the opposite sides of the two elastic telescopic rods 5 on the upper side, and the lower sponge pad 7 is located between the opposite sides of the two elastic telescopic rods 5 on the lower side. There are three support frames 3, and the three support frames 3 jointly support one protection tube body 4, and the three support frames 3 are fixedly connected to the upper surface of the fixed plate 2 and are distributed equidistantly laterally, and the upper surfaces of the three support frames 3 are fixedly connected with lifting rings 14. The setting of the lifting rings 14 is to facilitate the lifting operation during installation and maintenance, reduce the construction difficulty, and improve work efficiency.

[0028] In addition, the base 1 is designed as an isosceles trapezoid to provide more stable support. Compared with a rectangular or circular base, the trapezoidal base can better disperse the pressure from above, reduce stress concentration, and thus enhance the stability of the entire structure. Moreover, the isosceles trapezoidal design can better adapt to different soil types and ground conditions. Whether it is hard or soft ground, the isosceles trapezoidal design can adjust the contact mode with the ground through its shape to provide better support effect. The protective tube body 4 should be made of CPVC material as the main material of the cable protection tube. This material has excellent anti-corrosion properties and can effectively resist the erosion of acid and alkali substances and microorganisms in the soil, thereby extending the service life of the cable. The installation slide 10 and the slider 11 are set to make the protection tube body 4 easy to install and disassemble, and at the same time facilitate the adjustment of the position of the protection tube, improve the construction efficiency, and in order to prevent non-artificial sliding, the surface where the slider 11 contacts the installation slide 10 is provided with an anti-slip groove.

[0029] The working principle of the above embodiment is:

[0030] First, the elastic telescopic rods 5 on the upper and lower sides are stretched open to extend the cable to the inner side of the waterproof casing 6, and then the elastic telescopic rods 5 are loosened. After losing the external force, the elastic telescopic rods 5 will drive the waterproof casing 6 to move due to their own elastic reset characteristics, thereby closing the waterproof casings 6 on the upper and lower sides, thereby facilitating the installation of the cable. In addition, the elastic telescopic rods 5 can utilize the elastic material or structural characteristics inside them to deform when subjected to pressure or tension, thereby converting the vibration energy into the elastic potential energy of the material. This deformation and energy conversion process can effectively reduce the direct impact of vibration on the cable and reduce the stress on its structure.

[0031] At the same time, the sponge pad 7 has a porous structure, which makes it have good elastic deformation characteristics. When subjected to vibration, the sponge pad 7 can elastically deform through its internal pores, absorb external forces, and disperse these forces to a wider range. This deformation and dispersion process effectively reduces the impact and damage of vibration on structures and equipment;

[0032] In addition, the rubber sleeve 13 on the outside of the protection tube body 4 can increase the friction between the protection tube body 4 and the soil. First, the rubber material itself has a high friction coefficient, which means that the friction between the rubber and the soil is large. When the protection tube body 4 is buried in the soil, the rubber sleeve 13 can form a close contact with the soil particles, thereby preventing the protection tube body 4 from sliding when the soil is relatively wet or under the action of external forces.
