[0035] Reference Figures 1 to 6 As shown, an MPP power cable protection tube assembly includes a first tube body 1 and a second tube body 2, wherein the first tube body 1 and the second tube body 2 are spliced ​​together by a splicing assembly 3;

[0036] The splicing assembly 3 includes an inner ring 31 and an outer ring 32, wherein the inner ring 31 and the outer ring 32 are connected via a connecting portion 34, and a matching cavity 33 is formed between the inner ring 31 and the outer ring 32, wherein there are two matching cavities 33, which are respectively located at two ends of the splicing assembly 3;

[0037] The two matching cavities 33 are respectively provided with a first positioning cylinder 35 for positioning the first tube body 1 and a second positioning cylinder 36 for positioning the second tube body 2. The first tube body 1 is plugged into the first positioning cylinder 35, and the second tube body 2 is plugged into the second positioning cylinder 36.

[0038] The inner ring 31 is provided with an external thread, and the first positioning tube 35 and the second positioning tube 36 are both provided with an internal thread matching the external thread.

[0039] For the power cable protection tube installed above the ground, the power cable protection tube is usually installed at a higher position or a more remote position, and the power cable protection tube is usually fixed to the ground by a bracket. That is, the first tube body 1 and the second tube body 2 are both fixed to the ground by the bracket, or the second tube body 2 and the second tube body 2 are both fixed to the target position by the bracket, such as a frame, or other structures for setting the power cable protection tube.

[0040] Therefore, the positions of the first tube body 1 and the second tube body 2 are actually fixed, and the outer ring 32 of the splicing component 3 can also be fixed at the target position, or placed at the target position, that is, the outer ring 32 of the splicing component 3 can be fixed or not.

[0041] During the construction of the power cable protection tube, after the first tube body 1 and the second tube body 2 are fixed, the splicing assembly 3 is assembled, that is, the first positioning tube 35 and the second positioning tube 36 are both installed on the inner ring 31, and then the assembled splicing assembly 3 is placed between the first tube body 1 and the second tube body 2.

[0042] Rotate the first positioning cylinder 35 and the second positioning cylinder 36, and the second positioning cylinder 36 will move linearly in the direction of the first tube body 1 and the second tube body 2 until a part of the first tube body 1 is inserted into the second positioning cylinder 36, and a part of the second tube body 2 is inserted into the second positioning cylinder 36, thus completing the construction of the power cable protection tube assembly.

[0043] Reference Figures 1 to 6 As shown, in some embodiments, the first positioning cylinder 35 is provided with a first operating portion 351 for facilitating the rotation of the first positioning cylinder 35 , the cross-sectional shape of the first operating portion 351 is polygonal, the first operating portion 351 and the first positioning cylinder 35 are an integrated structure, and the first operating portion 351 is located outside the mating cavity 33 .

[0044] The second positioning cylinder 36 is provided with a second operating portion 361 for facilitating the rotation of the second positioning cylinder 36 . The cross-sectional shape of the second operating portion 361 is polygonal. The second operating portion 361 and the second positioning cylinder 36 are an integrated structure, and the second operating portion 361 is located outside the matching cavity 33 .

[0045] The first operating portion 351 and the second operating portion 361 are used to cooperate with a tool to rotate the first positioning cylinder 35 and the second positioning cylinder 36 .

[0046] Reference Figures 1 to 6 As shown, in some embodiments, the inner ring 31 is completely located inside the outer ring 32, and the outer ring 32 is further provided with a positioning portion 321 for preventing the outer ring 32 from rotating, and the cross-sectional shape of the positioning portion 321 is a polygon.

[0047] The positioning portion 321 and the outer ring 32 are an integrated structure. The outer ring 32 , the connecting portion 34 , and the inner ring 31 are an integrated structure. The connecting portion 34 is provided with a weight-reducing groove 341 for reducing the weight of the connecting portion 34 .

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the first positioning tube 35 is provided with a first drainage hole 352 , and the first drainage hole 352 is provided at the lower side of the first positioning tube 35 .

[0049] The first positioning tube 35 further includes a first water collection groove 353 disposed on the inner side wall of the first positioning tube 35 , and the first water collection groove 353 is communicated with the first drainage hole 352 .

[0050] The second positioning tube 36 is provided with a second drainage hole 362 , and the second drainage hole 362 is provided at the lower side of the second positioning tube 36 .

[0054] Taking the first positioning tube 35 as an example, after rainwater enters the first positioning tube 35, since a part of the first tube body 1 is located in the first positioning tube 35, the rainwater will not directly enter the first tube body 1, but will flow along the first tube body 1. Due to the setting of the first water accumulation groove 353, the rainwater enters the first water accumulation groove 353 under the action of its own gravity and is discharged through the first drainage hole 352.

[0055] The drainage method of the second positioning tube 36 is the same as that of the first positioning tube 35 .

[0056] The drainage method of the drainage groove 322 is that after the rainwater enters the outer ring 32, it flows along a part of the first positioning cylinder 35 or a part of the second positioning cylinder 36. Under the action of its own gravity, the rainwater enters the drainage groove 322 and is finally discharged from the matching cavity 33 through the drainage groove 322, thereby achieving the drainage purpose.

[0057] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.
