Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please refer to Figures 1 to 9 This utility model provides a ground wire protection device for power transmission lines, including a protective tube 01 and an anti-detachment mechanism 02 fitted onto both ends of the protective tube 01. A first elongated hole 11, with the same length as the protective tube 01, is formed along the axial direction of the outer wall of the protective tube 01, connecting to the interior of the protective tube 01. The anti-detachment mechanism 02 includes a connecting tube 21 and a disc 22 rotatably fitted onto the connecting tube 21. A second elongated hole 211, with the same length as the connecting tube 21, is formed along the axial direction of the outer wall of the connecting tube 21, connecting to the interior of the connecting tube 21. A third elongated hole 221, with the same length as the connecting tube 21, is formed along the radial direction of the disc 22, connecting to the interior of the connecting tube 21. To reduce the overall weight of the disc 22, several weight-reducing holes are also formed on the disc 22. In use, the ground wire is inserted into the protective tube 01 and the connecting tube 21 along the first elongated hole 11, the second elongated hole 211, and the third elongated hole 221 to protect the ground wire. Then, the disc 22 is rotated to make the third elongated hole 221 misaligned with the first elongated hole 11 on the protective tube 01, that is, an angle is formed between the third elongated hole 221 on the disc 22 and the first elongated hole 11 on the protective tube 01. The disc 22 can be used to prevent the ground wire from coming out of the protective tube 01 and the connecting tube 21.

[0028] In one embodiment, a locking ring 03 is fitted onto the connecting pipe 21. The locking ring 03 can limit the axial displacement of the disk 22 to prevent the disk 22 from shifting.

[0029] The locking ring 03 has a notch 31 that connects to the inside of the connecting pipe 21 in the radial direction, and the notch 31 corresponds to the second elongated hole 211 on the connecting pipe 21.

[0030] The locking ring 03 is located on both sides of the disc 22 and is threadedly connected to the connecting tube 21. After the ground wire is placed in the connecting tube 21, the disc 22 can be rotated circumferentially, causing the third elongated hole 221 to be misaligned with the first elongated hole 11 on the protective tube 01. By turning the locking ring 03, the disc 22 can be locked, thus protecting the ground wire. At this time, after the locking ring 03 is rotated, the position of its notch 31 will also change, and the notch 31 will also be misaligned with the first elongated hole 11, thus forming multiple protections to prevent the ground wire from detaching from the connecting tube 21 and the protective tube 01.

[0031] In one embodiment, the connecting pipe 21 has two discs 22. When a ground wire needs to be placed, the third elongated holes 221 on the two discs 22 are aligned with the first elongated holes 11 on the protective pipe 01, which facilitates the placement of the ground wire into the connecting pipe 21 and the protective pipe 01. After the ground wire is placed, the two discs 22 are rotated circumferentially so that the third elongated holes 221 on the two discs 22 and the first elongated holes 11 on the protective pipe 01 are misaligned, thereby enabling the ground wire to be removed from the protective pipe 01 using the discs 22. The optimal angle for the two discs 22 is to position the third elongated holes 221 at 180 degrees.

[0032] In one embodiment, the two ends of the protective tube 01 are fitted with connecting tubes 04, and a fourth elongated hole 41 with the same length as the connecting tube 04 is opened along the axial direction of the outer wall of the connecting tube 04, which communicates with the interior of the protective tube 01, so as to facilitate the insertion of the ground wire into the connecting tube 21 and the protective tube 01.

[0033] In one embodiment, a pin hole 05 is provided along the radial direction of the connecting pipe 04, penetrating both the connecting pipe 04 and the protective pipe 01, and a positioning hole 06 corresponding to the pin hole 05 is provided along the radial direction of the connecting pipe 21. By inserting the corresponding pin into the pin hole 05 and the positioning hole 06, the connecting pipe 21 and the protective pipe 01 can be connected together, thereby facilitating assembly and disassembly.

[0034] In one embodiment, a lubricating protective layer is provided on the inner wall of the protective tube 01. This layer covers the inner wall of the protective tube 01 to reduce friction between the ground wire and the protective tube 01, thereby reducing ground wire wear. The protective tube 01 can be made of high-strength, corrosion-resistant material to protect the ground wire from external damage. Simultaneously, a lubricating protective layer can also be provided on the inner wall of the connecting tube 21.

[0035] In one embodiment, there are at least two protective pipes 01 and anti-detachment mechanisms 02. By sequentially connecting each protective pipe 01 and anti-detachment mechanism 02 axially, multiple protective pipes 01 and anti-detachment mechanisms 02 can be assembled, thereby increasing the overall length and effectively solving the protection of the ground wire during power transmission line crossing construction.

[0036] In one embodiment, a follower rope may be added. This follower rope is made of high-strength, wear-resistant fiber material and has fixing rings or connecting buckles at both ends. It can be attached to the disc 22 and automatically adjusts its length and position as the ground wire moves. Under the influence of wind or other external forces, the follower rope can provide auxiliary fixing and guidance, ensuring the ground wire remains stable during protection.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
