A rotating rod is provided at the lower edge of the first lower baffle, and the first lower baffle is swingably connected to one end of the lower shell through the rotating rod.

[0014] With such a setting, the fixed connection of the first upper baffle is beneficial to preventing soil from entering the inside of the protective block. At the same time, the first upper baffle can enhance the overall strength of the protective block and improve the compressive strength of the protective block. The first lower baffle is convenient for adapting to cables of different models and thicknesses, and also provides sufficient space for the swing of the arc-shaped support plate.

[0015] Optionally: the second baffle has a second upper baffle and a second lower baffle. The second upper baffle is fixedly connected to the other end of the upper shell, and the lower edge of the second lower baffle is detachably connected to the other end of the lower shell.

[0019] With such a setting, both the above-mentioned first sealing ring and the above-mentioned second sealing ring can improve the sealing performance of the above-mentioned protective block.

[0020] Optionally: The above-mentioned protection mechanism has a limiting rod. One end of the limiting rod penetrates through the above-mentioned upper shell and is located inside the above-mentioned upper shell. An arc-shaped push plate is fixedly connected to the end of the limiting rod close to the inside of the above-mentioned upper shell.

[0021] With such a setting, the operator pushes the above-mentioned limiting rod to move the limiting rod into the interior of the above-mentioned upper shell. The above-mentioned arc-shaped push plate squeezes the cable under the thrust of the above-mentioned limiting rod, so that it is convenient for the device to be clamped on the cable, thereby avoiding unnecessary movement.

[0022] Optionally: An arc-shaped support plate is provided on one side of the above-mentioned arc-shaped push plate close to the above-mentioned lower shell. A plurality of movable frames are provided on one side of the arc-shaped support plate away from the arc-shaped push plate. One ends of the plurality of movable frames close to the arc-shaped support plate are evenly hinged to the side of the arc-shaped support plate away from the arc-shaped push plate, and one ends of the plurality of movable frames away from the arc-shaped support plate are evenly hinged to the inner wall of the above-mentioned lower shell.

[0023] With such a setting, the above-mentioned arc-shaped support plate can support the cable. The plurality of above-mentioned movable frames can enable the above-mentioned arc-shaped support plate to adjust its position, which is beneficial to adapting to cables of various models and thicknesses. The above-mentioned arc-shaped support plate is close to the cable under the upward lifting force of the plurality of above-mentioned movable frames.

[0024] Optionally: The above-mentioned arc-shaped support plate and the above-mentioned arc-shaped push plate are symmetrically distributed, and moreover, the above-mentioned arc-shaped support plate swings along the axial direction of the above-mentioned protective block through the plurality of above-mentioned movable frames.

[0025] With such a setting, mutual symmetry is required to clamp the cable. By swinging the arc-shaped supporting plate along the axial direction of the protection block through several of the above-mentioned movable frames, it is convenient to adjust the position of the arc-shaped supporting plate to adapt to cables of various models and thicknesses.

[0026] Optionally: a chute is provided in the wall of the upper housing. A plurality of concave holes are evenly arranged axially on one side of the limiting rod close to the chute. The chute communicates with the concave holes. Magnets are fixedly connected inside several of the concave holes;

[0027] A movable rod is arranged along the groove direction of the chute. One end of the movable rod away from the limiting rod is provided with a compression spring. One end of the compression spring is fixedly connected to the bottom of the chute, and the other end of the compression spring is fixedly connected to the end of the movable rod away from the limiting rod. One end of the movable rod close to the magnet abuts against the magnet under the action of the compression spring;

[0028] A connecting plate is fixedly connected to the upper surface of the end of the movable rod away from the limiting rod. The connecting plate penetrates through the upper housing.

[0029] With such a setting, by pulling the connecting plate, the connecting plate moves on the outer wall of the upper housing. The connecting plate pulls the movable rod to move in the chute. At the same time, when the movable rod moves, the magnets on one side of the movable rod move away from each other, and the movable rod compresses the spring. At this time, the limiting rod can push the arc-shaped push plate downward to make the arc-shaped push plate contact the top of the cable on the arc-shaped supporting plate. When the limiting rod moves to the appropriate position, release the connecting plate. One end of the movable rod abuts against the magnet in one of the concave holes of the limiting rod, thereby realizing the protection effect on the cable.

[0030] Optionally: the limiting mechanism has a limiting groove and a connecting block. The limiting groove is located on the other side of the lower housing. The connecting block is fixedly connected to the other side of the upper housing. The connecting block is adapted to the limiting groove. One end of the connecting block is connected with a leaf spring. One end of the leaf spring away from the connecting block is provided with a fixing plate. One end of the fixing plate is hingedly connected to one end of the connecting block, and the other end of the fixing plate is fixedly connected to the leaf spring;

[0031] A connecting rod is provided at one end of the lower housing close to the limiting groove. The connecting rod is slidably communicated with the limiting groove and abuts against the fixing plate.

[0032] With such a setting, during installation, the connecting block of the above-mentioned limiting mechanism is located in the above-mentioned limiting groove, and the above-mentioned leaf spring elastically pushes the above-mentioned fixed plate to expand, so that the above-mentioned connecting block can be clamped in the above-mentioned limiting groove. By pushing the above-mentioned connecting rod, the above-mentioned connecting rod pushes the above-mentioned fixed plate to compress the above-mentioned leaf spring, and the above-mentioned connecting block can leave the above-mentioned limiting groove, which is beneficial to opening the device for recycling.

[0033] Optionally: a groove is provided at the bottom of the inner groove at the other end of the above-mentioned lower housing, and a convex block is provided on one side of the above-mentioned second lower baffle close to the above-mentioned groove, and the above-mentioned convex block is fitted in the above-mentioned groove.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] Embodiment

[0045] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , this embodiment provides a photovoltaic power generation operation and maintenance line marking device, including a protective block 1;

[0046] The protective block 1 has an upper housing 2 and a lower housing 3, and the upper housing 2 and the lower housing 3 are detachably connected to each other;

[0047] One end of the protective block 1 is provided with a first baffle 4, the first baffle 4 is swingably connected to one end of the protective block 1, the other end of the protective block 1 is provided with a second baffle 5, the second baffle 5 is detachably connected to the other end of the protective block 1, and a through hole 6 is opened at the axis of the first baffle 4 and the second baffle 5;

[0048] The interior of the protection block 1 is provided with a protection mechanism 7. One side of the upper housing 2 and the lower housing 3 is hinged to each other, and a limiting mechanism 8 is provided between the other sides of the upper housing 2 and the lower housing 3. The other side of the upper housing 2 is detachably connected to the other side of the lower housing 3 through the limiting mechanism 8.

[0049] During use, the upper housing 2 and the lower housing 3 of the protection block 1 are opened, so that the protection mechanism 7 clamps the cable. At this time, the cable is located in the through hole 6 of the first baffle 4 and the second baffle 5. Finally, the first baffle 4 is connected to the other side of the second baffle 5 through the limiting mechanism 8.

[0050] A photovoltaic power generation operation and maintenance line marking device disclosed in this embodiment can wrap the cable to mark the cable due to the provision of the protection block 1. The protection mechanism 7 can clamp the cable, and the limiting mechanism 8 can lock the upper housing 2 and the lower housing 3 to each other, achieving the protection effect on the cable line. Furthermore, a photovoltaic power generation operation and maintenance line marking device has the beneficial effects of simple and convenient operation steps, facilitating the staff to quickly mark the line, good clamping effect, and being able to adjust the position arbitrarily.

[0051] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the first baffle 4 has a first upper baffle 9 and a first lower baffle 10. The first upper baffle 9 is fixedly connected to one end of the upper housing 2. The lower edge of the first lower baffle 10 is provided with a rotating rod 11. The first lower baffle 10 is swingably connected to one end of the lower housing 3 through the rotating rod 11. The fixed connection of the first upper baffle 9 is beneficial to preventing soil from entering the interior of the protection block 1. At the same time, the first upper block can enhance the overall strength of the protection block 1 and improve the compressive strength of the protection block 1. The first lower block is convenient for adapting to cables of different models and thicknesses, and also provides sufficient space for the swing of the arc-shaped support plate 18.

[0052] In this embodiment, the first lower baffle 10 is set to be opened and closed through the rotating rod 11 to cooperate with the arc-shaped support plate 18. Because when the cable is too thick, the arc-shaped support plate 18 will swing and displace to increase the distance between the arc-shaped support plate 18 and the arc-shaped push plate 17. At this time, the arc-shaped support plate 18 will push open the first lower baffle 10, facilitating sufficient space for the arc-shaped support plate 18 to displace.

[0053] The second baffle 5 has a second upper baffle 12 and a second lower baffle 13. The second upper baffle 12 is fixedly connected to the other end of the upper housing 2. The lower edge of the second lower baffle 13 is detachably connected to the other end of the lower housing 3. The fixed connection of the second upper baffle 12 is beneficial to preventing soil from entering the interior of the protection block 1. At the same time, the second upper block can enhance the overall strength of the protection block 1 and improve the compressive strength of the protection block 1. The second lower baffle 13 is detachable for the final limiting of the cable.

[0054] On one side of the first baffle 4 close to the second baffle 5, there is a first sealing ring 14, and the first sealing ring 14 is fixedly connected at the through hole 6 of the first baffle 4; on one side of the second baffle 5 close to the first baffle 4, there is a second sealing ring 15, and the second sealing ring 15 is fixedly connected at the through hole 6 of the second baffle 5. Both the first sealing ring 14 and the second sealing ring 15 can improve the sealing performance of the protection block 1.

[0055] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in, the protection mechanism 7 has a limiting rod 16. One end of the limiting rod 16 penetrates through the upper shell 2 and is located inside the upper shell 2. A curved push plate 17 is fixedly connected to the end of the limiting rod 16 close to the inside of the upper shell 2. The operator pushes the limiting rod 16 to move the limiting rod 16 into the inside of the upper shell 2. The curved push plate 17 squeezes the cable under the thrust of the limiting rod 16, so that it is convenient for the device to be clamped on the cable, thereby avoiding unnecessary movement.

[0056] On one side of the curved push plate 17 close to the lower shell 3, there is a curved support plate 18. On the side of the curved support plate 18 away from the curved push plate 17, there are several movable frames 19. One end of the several movable frames 19 close to the curved support plate 18 is evenly hinged to the side of the curved support plate 18 away from the curved push plate 17, and one end of the several movable frames 19 away from the curved support plate 18 is evenly hinged to the inner wall of the lower shell 3. The curved support plate 18 can support the cable, and the several movable frames 19 can enable the curved support plate 18 to adjust its position, which is beneficial to adapting to cables of various models and thicknesses. The curved support plate 18 is close to the cable under the upward lifting force of the several movable frames 19. When the curved push plate 17 excessively squeezes the cable, under the elastic swinging action of the several movable frames 19, the curved support plate 18 will move downward accordingly. In this way, the cable is clamped and the cable is prevented from being damaged by excessive extrusion, which is beneficial for the construction personnel to install the device on the cable.

[0057] The curved support plate 18 and the curved push plate 17 are symmetrically distributed. Moreover, the curved support plate 18 swings along the axial direction of the protection block 1 through the several movable frames 19. Only by being symmetrically distributed can it be clamped on the cable, and the curved support plate 18 swinging along the axial direction of the protection block 1 through the several movable frames 19 is convenient for adjusting the position of the curved support plate 18 to adapt to cables of various models and thicknesses.

[0058] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a chute 20 is formed in the shell wall of the upper shell 2. A number of concave holes 21 are evenly axially formed on one side of the limiting rod 16 close to the chute 20. The chute 20 communicates with the concave holes 21. Magnets 22 are fixedly connected inside a number of the concave holes 21;

[0059] A movable rod 23 is arranged in the groove direction of the chute 20. One end of the movable rod 23 far from the limiting rod 16 is provided with a compression spring 24. One end of the compression spring 24 is fixedly connected to the bottom of the chute 20, and the other end of the compression spring 24 is fixedly connected to the end of the movable rod 23 far from the limiting rod 16. One end of the movable rod 23 close to the magnet 22 abuts against the magnet 22 under the action of the compression spring 24;

[0060] A connecting plate 25 is fixedly connected to the upper surface of the end of the movable rod 23 far from the limiting rod 16. The connecting plate 25 penetrates through the upper shell 2. By pulling the connecting plate 25, the connecting plate 25 moves on the outer wall of the upper shell 2. The connecting plate 25 pulls the movable rod 23 to move in the chute 20. At the same time, when the movable rod 23 moves, the magnets 22 on one side of the movable rod 23 move away from each other, and the movable rod 23 compresses the spring. At this time, the limiting rod 16 can push the arc-shaped push plate 17 to move downward, so that the arc-shaped push plate 17 contacts the top of the cable on the arc-shaped supporting plate 18. When the limiting rod 16 moves to an appropriate position, release the connecting plate 25. One end of the movable rod 23 closely abuts against the magnet 22 in one of the concave holes 21 of the limiting rod 16, thereby realizing the protection effect on the cable.

[0061] The limiting mechanism 8 has a limiting groove 26 and a connecting block 27. The limiting groove 26 is located on the other side of the lower shell 3. The connecting block 27 is fixedly connected to the other side of the upper shell 2. The connecting block 27 is adapted to the limiting groove 26. One end of the connecting block 27 is connected with a leaf spring 28. One end of the leaf spring 28 far from the connecting block 27 is provided with a fixing plate 29. One end of the fixing plate 29 is hinged to one end of the connecting block 27, and the other end of the fixing plate 29 is fixedly connected to the leaf spring 28; A connecting rod 30 is arranged at one end of the lower shell 3 close to the limiting groove 26. The connecting rod 30 is slidably communicated with the limiting groove 26 and abuts against the fixing plate 29. During installation, the connecting block 27 of the limiting mechanism 8 is located in the limiting groove 26. The elastic pushing of the leaf spring 28 to expand the fixing plate 29 can make the connecting block 27 be clamped in the limiting groove 26. By pushing the connecting rod 30, the connecting rod 30 pushes the fixing plate 29 to compress the leaf spring 28, and the connecting block 27 can leave the limiting groove 26, which is beneficial to opening the device for recycling.

[0062] A groove 31 is formed at the bottom of the inner groove at the other end of the lower shell 3. One side of the second lower baffle 13 close to the groove 31 has a convex block 32. The convex block 32 is adapted in the groove 31. The second lower baffle 13 and the groove 31 cooperate with each other through the convex block 32, so that the second baffle 5 realizes the limiting and fixing of the cable and prevents the device from moving on the cable.

[0063] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,In this embodiment, the specific usage steps of the photovoltaic power generation operation and maintenance line marking device are as follows: When it is necessary to mark the cable, place the lower housing 3 of the protection block 1 at the bottom of the cable line. By swinging the arc-shaped support plate 18, the arc-shaped support plate 18 swings under the action of several movable frames 19. Utilize the swing of the arc-shaped support plate 18 to push the first lower baffle 10 to rotate, so that the arc-shaped support plate 18 is located inside the protection block 1. Place the damaged cable line on the arc-shaped support plate 18 to achieve the protection effect on the cable line. By pushing the upper housing 2 and the lower housing 3 to close, the upper housing 2 drives the connecting block 27 to move synchronously. By inserting the bottom of the connecting block 27 into the limiting groove 26 of the lower housing 3, at this time, the fixed plate 29 pushes the leaf spring 28 to be compressed. In this way, the connecting block 27 will slide into the limiting groove 26, and the fixed plate 29 will expand again under the elastic action of the leaf spring 28, and the connecting block 27 is restricted in the limiting groove 26, achieving the fixing effect on the overall protection block 1. When opening, just press the connecting rod 30 to enable the fixed plate 29 to push the leaf spring 28 to be compressed, so that the upper housing 2 and the lower housing 3 are separated; By pulling the connecting plate 25, the connecting plate 25 pulls the movable rod 23, and the movable rod 23 moves. At the same time, when the movable rod 23 moves, the magnetic blocks 22 on one side of the movable rod 23 move away from each other, and the movable rod 23 forms a compression effect on the spring. At this time, the limiting rod 16 can push the arc-shaped push plate 17 to move downward, so that the arc-shaped push plate 17 contacts the top of the cable on the arc-shaped support plate 18. When the limiting rod 16 moves appropriately, release the connecting plate 25, and one end of the movable rod 23 abuts against the magnetic block 22 in one of the concave holes 21 of the limiting rod 16, thereby achieving the protection effect on the cable line; Finally, the second lower baffle 13 is fixed to the other end of the protection block 1 by inserting the convex block 32 into the groove 31 to limit the cable.

[0064] In this embodiment, when the cable is buried in the soil and the cable is damaged and needs to be dug out for repair, since the specific depth position is not clear, it is easy to cut off the cable by the excavator. Therefore, when burying the cable, fixing this device evenly on the cable can play a warning role. As long as this device is dug out, it proves that the cable is not far away.

[0065] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
