[0042] Embodiment one: please refer to Figures 1-8As shown, this embodiment provides a photovoltaic cable wiring device, including a first wiring pipe 1 and a second wiring pipe 2. The first wiring pipe 1 has a first tidying ring 12 for tidying up one end of the cable wire inside, and the second wiring pipe 2 has a second tidying ring 22 for tidying up the other end of the cable wire inside. Both the first tidying ring 12 and the second tidying ring 22 have stripping components 3 on their outer sides. The stripping components 3 have a tensioning component 322 for reducing shaking and buffering, and a beveled blade 3214 for stripping. The stripping components 3 have an adjusting device 4 for adjusting the tightness of the cable on the side away from the first wiring pipe 1. The cable sheath is stripped by rotating the first wiring pipe 1 and the second wiring pipe 2, using the beveled blade 3214 and the tensioning component 322, while the cable is sealed and fixed by the adjusting device 4.

[0043] like Figure 8 As shown, one end of a first column 11 is fixedly connected to the inner wall of the middle end of the first connector 1, and the other end of the first column 11 is fixedly connected to a first sorting ring 12. A threaded groove 13 is opened on the inner wall of one end of the first connector 1. One end of a second column 21 is fixedly connected to the inner wall of the second connector 2, and the other end of the second column 21 is fixedly connected to a second sorting ring 22. A threaded protrusion 23 is fixedly connected to the outer wall of the second connector 2 near the first connector 1. The inner diameter of the first sorting ring 12 is the same as the outer diameter of the second sorting ring 22, and the threaded protrusion 23 fits into the threaded groove 13.

[0044] like Figures 4-7 As shown, the peeling assembly 3 includes a sliding ring 31. An annular groove 311 is formed on the outer wall of the sliding ring 31. An inclined surface 312 is formed on the outer side of the inner wall of the sliding ring 31. A fixing ring 32 is provided on the inner side of the sliding ring 31. The inner wall of the sliding ring 31 is slidably connected to the outer wall of the fixing ring 32. A tapered member 3211 is provided on the inner side of the end of the fixing ring 32 away from the first connecting pipe 1. One end of a spring 3212 is fixedly connected to the bottom of the tapered member 3211. The other end of the spring 3212 is fixedly connected to a dividing fixed member. The fixed ring 3213 is rotatably connected to the inner side of the dividing fixed ring 3213 with an oblique blade 3214. The first connecting pipe 1 and the second connecting pipe 2 are each provided with a stripping component 3 and an adjusting device 4 on one side. The outer wall of the first fixed ring 32 is provided with an irregular groove 321. The inner side of the irregular groove 321 is provided with a tensioning component 322. The tensioning component 322 includes a bending pry bar 3221. The bending part of the bending pry bar 3221 is rotatably connected to the inner wall of the irregular groove 321. One end of the bending pry bar 3221 is provided with an elastic ring 3222.

[0045] like Figure 5As shown, a sealing ring 323 is slidably connected to the outer wall of the first fixing ring 32. The sealing ring 323 has a second annular groove 3231 on the side near the sliding ring 31. The width of the second annular groove 3231 matches the width of the sliding ring 31. A sliding member 324 is fixedly connected to the side of the sealing ring 323 away from the sliding ring 31. The sliding member 324 is slidably connected to the outer wall of the first fixing ring 32. A protruding ring 3241 is fixedly connected to the inner wall of the second annular groove 3231. One side of the elastic ring 3222 is in contact with one end of the bent rocker arm 3221, and the upper end on the same side is fixedly connected to the protruding ring 3241.

[0046] Therefore, when it is necessary to strip the insulation of photovoltaic cables, such as Figures 2-4 As shown, the worker inserts the cut end of the photovoltaic cable into the adjusting device 4, moving it towards the first and second sorting rings 12 and 22, passing through their inner sides. When it passes the oblique blade 3214, it pushes the blade towards the first sorting ring 12 and rotates it at a certain angle. Then, the worker squeezes the sealing ring 44 and pulls it outwards, causing the photovoltaic cable and the first fixing ring 32 to move outwards together. Figure 7 As shown, at this time, the sliding ring 31 slides to the right on the first fixed ring 32. When the sliding ring 31 passes the tapered part 3211, the tapered part 3211 slides down continuously under the obstruction of the inclined surface 312 and pushes the inclined blade 3214 to contract inward, cutting the outer sheath of the photovoltaic cable and peeling off the outer sheath of the photovoltaic cable.

[0047] It should be noted that the oblique blade 3214 is distributed in multiple annular segments. When the conical part 3211 pushes the oblique blade 3214 downward, the multiple annular oblique blades 3214 contract inward and merge into a complete circle for cutting. Since the operation of No. 1 connector 1 and No. 2 connector 2 is the same, only one of them will be introduced in the context.

[0048] Example 2: Unlike Example 1, in order to achieve sealing and fixing of the photovoltaic cable, such as... Figure 6As shown, the adjusting device 4 comprises a second fixed ring 41 fixedly connected to the outer wall of the sliding piece 324, the inner side of the sliding piece 324 is provided with an adjusting assembly 42, the adjusting assembly 42 comprises a sliding column 421, one end of the second spring 422 fixedly connected to the sliding column 421 is arranged through the outer wall of the sliding piece 324 and the second fixed ring 41, the other end of the second spring 422 is fixedly connected with an adjusting ring 423, the sliding column 421 is rotatably connected with a flap 43, the middle end of the flap 43 is rotatably connected to the inner side of the second fixed ring 41, the flap 43 is fixedly connected with a protruding block 431 at the bottom of the end away from the sliding column 421, the bottom of the second fixed ring 41 is slidably connected with a sealing ring 44, the top of the sealing ring 44 is provided with a V-shaped groove 441, and the V-shaped groove 441 is matched with the protruding block 431.

[0049] Therefore, when it is necessary to fix and seal the photovoltaic cable after peeling, according to the embodiment one, as shown, Figure 7 After peeling the photovoltaic cable, the staff pushes the pinched sealing ring 44 again to the inner side, at this time, the sealing ring 44 first slides at the bottom of the second fixed ring 41 to the direction of the first wire tube 1, and is abutted against the side of the sliding piece 324 away from the first wire tube 1, and simultaneously drives the sliding piece 324 and the sealing ring 323 to slide to the sliding ring 31, until the inner wall of the sliding piece 324 is attached to the side of the first fixed ring 32, and drives the first fixed ring 32 to slide to the right side, at this time, the sliding ring 31 slides to the left on the first fixed ring 32, when passing through the bent flap 3221, the bevel 312 gradually presses down one end of the bent flap 3221, and rocks the other end of the bent flap 3221 to be close to the elastic ring 3222, and extrudes the elastic ring 3222, because the upper end of the elastic ring 3222 is fixedly connected with the protruding ring 3241 in the sliding piece 324, so the sliding piece 324 is driven to the right side and the sealing ring 323 is tightened, at the same time, the sliding ring 31 is gradually close to the sealing ring 323 and is fixed with the second annular groove 3231, so that the outer wall of the first wire tube 1 is sealed, to ensure that the embedded photovoltaic cable will not be damaged by rainwater seepage in the underground;

[0050] It should be noted that in the process of pushing the sealing ring 44, the protruding block 431 at the bottom of the flap 43 will be separated from the V-shaped groove 441, at this time, the flap 43 is rocked and drives the sliding column 421 to press down, and in the process of pressing down the sliding column 421, the adjusting ring 423 is also driven to contract to the inner side (the adjusting ring 423 is the same as the oblique blade 3214 in the embodiment one), and clamps the outer wall of the photovoltaic cable to fix it, at the same time, when the protruding block 431 is separated from the V-shaped groove 441, the sealing ring 44 is also pressed with greater force, so that the sealing ring 44 is closer to the outer wall of the photovoltaic cable.

[0051] As shown, Figure 8As shown, finally, the first connector tube 1 and the second connector tube 2 are rotationally sealed through the threaded groove 13 and the threaded protruding piece 23, the wires in the first arranging ring 12 and the second arranging ring 22 are twisted by the rotation of the worker, and the first arranging ring 12 and the second arranging ring 22 gradually connect, and finally the wiring is completed, the whole process is convenient and simple to operate, and the work efficiency of the worker can be ensured.

[0052] Embodiment three: the embodiment provides a use method of the photovoltaic cable wiring device, and the method comprises the following steps:

[0053] S1, first, the photovoltaic cable is introduced into the first arranging ring 12 from the inner side of the self-adjusting device 4, and is resisted by the inclined blade 3214;

[0054] S2, then the worker moves the photovoltaic cable by pinching and pulling the sealing ring 44 outward, at this time, the inclined blade 3214 rotates and penetrates the cable sheath to cut and peel off in the moving direction of the photovoltaic cable;

[0055] S3, then the adjusting device 4 is pushed towards the first connector tube 1, and the second annular groove 3231 is fixed with the sliding ring 31;

[0056] S4, finally, the worker rotates and tightens the first connector tube 1 and the second connector tube 2 through the threaded groove 13 and the threaded protruding piece 23, so that the first arranging ring 12 and the second arranging ring 22 coincide, and the ends of the cable are twisted by the rotation of the first connector tube 1 or the second connector tube 2.

[0057] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
