[0022] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate the described embodiments. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0023] In this embodiment, the device is made of stainless steel or galvanized carbon steel to ensure its mechanical strength and corrosion resistance, and to enhance its aesthetics and durability.

[0024] like Figures 1-2 As shown, a cable protection pipe protection and grounding device includes a semi-tubular component A 1 and a component B 8. The tubular body formed by connecting the components A 1 and B 8 has a sealed bottom and an open top and vertical surface.

[0025] The A component 1 includes an inner wall 2 and an outer wall 3, forming a first cavity between the inner wall 2 and the outer wall 3. The outer surface of the A component 1 is provided with a left wall lug 5 and a right wall lug 6 near the top. Both the left wall lug 5 and the right wall lug 6 are provided with a first locking hole 16. The bottom of the A component 1 is thickened to increase the protective strength. The bottom of the A component 1 is designed with a first drain outlet 4 to drain condensate or rainwater from the device in a timely manner.

[0026] The B component 8 includes an inner wall 9 and an outer wall 10, forming a second cavity between the inner wall 9 and the outer wall 10. The outer surface of the B component 8 is provided with a left wall lug 12 and a right wall lug 13 near the top. Both the left wall lug 12 and the right wall lug 13 are provided with a second locking hole 18. The bottom of the B component 8 is thickened to increase its protective strength. The bottom of the B component 8 is designed with a second drain outlet 11 to drain condensate or rainwater from the device in a timely manner.

[0027] The inner wall 2 and outer wall 3 of component A, and the inner wall 9 and outer wall 10 of component B, are both wide at the bottom and narrow at the top, suitable for protective tubes of different wall thicknesses, ensuring tight contact with the protective tube. The inner wall 2 of component A is 6mm longer than the outer wall 3 of component A, forming a first inner wall mating surface 7. The inner wall 9 of component B is 6mm longer than the outer wall 10 of component B, forming a second inner wall mating surface 14. Locking grounding bolts 15 are installed at both the first locking hole 16 and the second locking hole 18. The first cavity and the second cavity are connected to form cavity 17.

[0028] Components A1 and B8 are clamped and fixed at the opening of the protective pipe, eliminating the need for threading the protective pipe or welding grounding bolts, thus avoiding damage to the anti-corrosion layer of the protective pipe. This installation method not only reduces installation difficulty but also shortens construction time. Grounding bolt 15 secures Components A1 and B8 to the opening of the protective pipe, ensuring even force distribution and reliable installation. This prevents the protective device from detaching due to external forces on the cable, guaranteeing that the cable will not be damaged or short-circuited. Drainage outlets are designed at the bottom of Components A1 and B8 to promptly drain condensate or rainwater from the device, preventing rust in the cavity. The inner walls of Components A1 and B8 (inner wall 2 of Component A and inner wall 9 of Component B) are designed with an interlaced connection, ensuring a complete and integrated inner wall structure that effectively protects the cable.

[0029] Furthermore, the shape of the inner and outer walls (inner wall 2 of component A, inner wall 9 of component B, outer wall 3 of component A, and outer wall 10 of component B) of components A and B, with a wide bottom and narrow top opening, is suitable for protective pipes of different wall thicknesses, ensuring tight contact with the protective pipe and providing better protection. To improve the strength under stress, the bottom of both components is thickened. At the same time, the bottom is reinforced with rounded corner stamping to protect the cable, effectively preventing burrs and sharp edges from cutting or tearing the cable. Both components are designed with double-sided wall lugs and equipped with locking grounding bolts 15, facilitating the installation of grounding wires for rows of protective pipes and meeting grounding standardization requirements.

[0030] like Figure 3 As shown, when the cable protection pipe is installed but the cable is not yet run through the pipe, the steps for installing the cable protection pipe and grounding device are as follows:

[0031] First, assemble component A1 and component B8 into a cylindrical structure;

[0032] Next, insert the locking grounding bolt 15 into the first locking hole 16 and the second locking hole 18 to ensure that the bolt can securely fix the two components;

[0033] Inspect the overlapping portion of the first inner wall mating surface 7 and the second inner wall mating surface 14 to ensure that they are tightly joined together;

[0034] Based on the depth of cavity 17, make a marking line at the opening of the protective tube;

[0035] Align the opening of the top cavity 17 with the wall of the protective tube, and then push the bottom of the device forcefully to make it fit tightly against the tube wall;

[0036] Check whether the top of the outer wall 3 of component A and the outer wall 10 of component B are aligned with the marking line on the protective tube;

[0037] Grounding wires are installed at the left wall lug 5 and right wall lug 6 of component A and the left wall lug 12 and right wall lug 13 of component B.

[0038] Tighten and lock the grounding bolt 15 to ensure the entire device is secure and reliable;

[0039] Check whether the inner wall (inner wall 2 of component A, inner wall 9 of component B) and outer wall (outer wall 3 of component A, outer wall 10 of component B) of the device are tightly fitted to the wall of the protective tube;

[0040] Finally, check whether the first drain outlet 4 and the second drain outlet 11 are unobstructed and ensure that there are no foreign objects blocking them.

[0041] Once the cable protection conduit is installed and the cable is secured through the conduit, the steps for installing the cable protection conduit and grounding device are as follows:

[0042] With the cable as the center, component A1 and component B8 are fitted onto the cable and assembled into a cylindrical structure;

[0043] Insert the locking grounding bolt 15 into the corresponding locking hole to ensure that the two components can be firmly fixed together;

[0044] Check the tightness of the overlap of the inner wall mating surfaces to ensure there are no gaps;

[0045] Mark the opening of the protective tube according to the depth of the cavity of the device;

[0046] Place the cable that has been fixed in the conduit in the center of the protective conduit;

[0047] Align the opening of the cavity at the top of the device with the wall of the protective tube, and then push the bottom of the device firmly to make it fit tightly against the tube wall.

[0048] Check whether the top of the outer wall of the device is aligned with the marking line on the protective tube;

[0049] Install a grounding wire at the wall lugs of the component to ensure proper grounding;

[0050] Tighten the grounding bolts to ensure the entire device is secure and reliable;

[0051] Check whether the inner and outer walls of the device are tightly fitted to the wall of the protective pipe, and whether the drain outlet is unobstructed.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
