These columns 1 are provided with the same support bar 2 in the same column, and the heights of the columns 1 in the same column decrease in sequence to form a slope. A plurality of photovoltaic panels 3 are arranged between two adjacent support bars 2, and the grounding wires on the photovoltaic panels 3 are connected to the support bar 2 to ensure the grounding safety of the photovoltaic panels 3.

[0042] On one side of each column 1, a guide seat 10 is provided. A through hole 11 is opened at the top of the guide seat 10, and a grounding rod 9 is arranged in the through hole 11. The bottom end of the grounding rod 9 extends into the ground, and the other end is connected to the support bar 2 through a grounding lead 16. In this way, the grounding rod 9 can introduce lightning into the ground to protect the photovoltaic panels 3 from lightning damage.

[0043] In order to insert the grounding rod 9 into the ground, the system is provided with a pressing mechanism. The pressing mechanism is detachably arranged on the column 1 and includes two support plates 4 inserted on one side of the column 1. The same connecting plate 5 is fixedly arranged on one side of the two support plates 4. The bottom of the lower support plate 4 abuts against the top of the guide seat 10. To increase the stability of the support plate 4, the support plate 4 can be fixed to the column 1 by an additional binding method. Two guide rods 8 are fixedly arranged between the two support plates 4, and the outer walls of the two guide rods 8 are slidably sleeved with the same connecting seat 7. The bottom of the connecting seat 7 abuts against the top of the grounding rod 9. A driving member is arranged on the top of the upper support plate 4 to provide lifting power for the connecting seat 7. A first jack 12 is opened on one side of the guide seat 10, and a first inserting bar 13 is inserted into the first jack 12. The first inserting bar 13 is fixedly connected to the lower support plate 4 to further ensure the stability of the pressing mechanism.

[0044] To further facilitate the pressing of the grounding rod 9 into the ground, a first sliding ring 20 is slidably sleeved on the outer wall of the first screw rod 17. The first sliding ring 20 is rotatably arranged through the top of the connecting seat 7. The top of the connecting seat 7 is rotatably arranged through a first rotating ring 18.

A second pin 35 is arranged in the second positioning hole 36. A plurality of second pins 35 are fixedly connected to the first rotating ring 18. Meshing gears 19 are fixedly sleeved on the outer walls of the first rotating ring 18 and the first sliding ring 20 for driving the grounding rod 9 to rotate. A spiral blade 24 for drilling soil is fixedly wound around the outer wall of the grounding rod 9. When the first screw rod 17 rotates, it can also rotate through the first sliding ring 20. During the rotation of the first sliding ring 20, it can drive the first rotating ring 18 to rotate through the two meshing gears 19, and can drive the grounding rod 9 to rotate through the inserted second pins 35. Moreover, the spiral blade 24 is wound around the outer wall of the grounding rod 9, making it very easy to drill into the ground.

[0045] In order to increase the friction between the grounding rod 9 and the ground, the system is also provided with a reinforcement mechanism.

A rectangular hole 33 is opened on the outer wall of the grounding rod 9. One end of the connecting bar 32 is located inside the rectangular hole 33. When the second screw rod 22 is rotated, the connecting bar 32 can be driven to move out of the rectangular hole 33 through the second rotating ring 30, so that the connecting bar 32 is inserted into the ground from the side to increase the friction between the grounding rod 9 and the ground. A rectangular block 23 for the wrench to rotate is fixedly arranged on the top of the second screw rod 22, which is convenient for operation.

The fixing mechanism includes a socket 14 arranged on the guide seat 10, and the socket 14 is inserted into the grounding rod 9. One side of the socket 14 is provided with a U-shaped opening 37 corresponding to the grounding rod 9, which facilitates the insertion of the socket 14 and avoids the socket 14 from touching the grounding rod 9. A protective shell 15 is fixedly arranged at the top of the socket 14, and the middle part of the grounding lead 16 is located inside the protective shell 15 to protect the grounding lead 16 from being damaged. A relief opening 38 for the grounding lead 16 to pass through is arranged at the bottom end of the protective shell 15. The protective shell 15 is fixedly connected to the column 1 to ensure the stability of the fixing mechanism.

[0047] This application can be used in the field of photovoltaic power generation, and can also be used in other fields applicable to this application.

[0048] Example 2: Refer to Figures 1-9 , on the basis of Example 1, an improvement is made: A mountain photovoltaic power generation lightning protection grounding system, which is applied to the field of photovoltaic power generation. The driving member includes a speed reducer 6 arranged on the top of the support plate 4, and a first screw rod 17 rotatably arranged through between two support plates 4. The top end of the first screw rod 17 is fixedly connected to the output end of the speed reducer 6. A nut ring 21 is fixedly arranged through the bottom of the connecting seat 7, and the nut ring 21 is threadedly sleeved on the first screw rod 17. When the speed reducer 6 is driven manually or by a motor, the first screw rod 17 can be driven to rotate, so that the nut ring 21 moves up and down on the first screw rod 17, and the nut ring 21 drives the connecting seat 7 to move up and down, thereby pressing the grounding rod 9 into the ground.

[0049] A second sliding ring 27 is also slidably sleeved on the outer wall of the second screw rod 22, and a plurality of first pin columns 28 are fixedly arranged at the bottom of the second sliding ring 27. A first positioning hole 29 corresponding to the first pin column 28 is arranged at the top of the grounding rod 9 for limiting the second screw rod 22. At the same time, a connecting ring 26 is sleeved on the outer wall of the second screw rod 22, and one end of the grounding lead 16 is fixedly connected to the connecting ring 26. A first nut block 25 is threadedly sleeved on the outer wall of the second screw rod 22 for further limiting the second screw rod 22 and fixing the connecting ring 26 and the second sliding ring 27, so that loosening will not occur during use.

[0050] Two groups of second jacks 40 are also arranged on one side of the grounding rod 9, and the two groups of second jacks 40 are respectively located at the top and bottom of the guide seat 10. Second insertion strips 39 are inserted into the second jacks 40, and a plurality of second insertion strips 39 are all fixedly connected to the socket 14, realizing the insertion connection between the grounding rod 9 and the socket 14, and further increasing the connection stability.

[0051] On one side of the column 1, a positioning groove 43 adapted to the protective shell 15 is provided, and one side of the protective shell 15 is located within the positioning groove 43. On one side of the column 1, a plurality of second nut blocks 41 located within the protective shell 15 are also fixedly provided, and a bolt 42 corresponding to the second nut block 41 penetrates through one side of the protective shell 15. One end of the bolt 42 is threadedly connected within the second nut block 41, thereby fixing the protective shell 15 to the column 1.

[0052] In this application, during use, first install the column 1 on the mountain, then clamp the support plate 4 on the column 1, and insert the first insertion strip 13 into the first insertion hole 12. When necessary, a binding tool can be added to one side of the connecting plate 5 to fix the connecting plate 5 to the column 1. At the same time, insert the grounding rod 9 into the through hole 11, and then drive the reduction gear 6 to rotate manually or by a motor. The rotation of the reduction gear 6 can drive the first screw rod 17 to rotate. The rotation of the first screw rod 17 can drive the nut ring 21 to move downward. The downward movement of the nut ring 21 can drive the connecting seat 7 to move downward, which can drive the first rotating ring 18 to be inserted into the step groove 34, and make the second pin 35 inserted into the corresponding second positioning hole 36. Continue to rotate the reduction gear 6, continue to drive the connecting seat 7 to move downward, and can drive the grounding rod 9 to move downward into the ground through the first rotating ring 18. During the rotation of the first screw rod 17, it can drive the first sliding ring 20 to rotate. The rotation of the first sliding ring 20 can drive the first rotating ring 18 to rotate through two meshing gears 19. The rotation of the first rotating ring 18 can drive the grounding rod 9 to rotate through the second positioning hole 36 and the second pin 35, and can drill the grounding rod 9 into the ground through the spiral blade 24 until the two groups of second insertion holes 40 are respectively located at the top and bottom of the guide seat 10;

[0053] Use the above method to drill the grounding rods 9 on one side of the column 1 into the ground in sequence, then fix the support bars 2 on multiple columns 1, install the photovoltaic panels 3 on two adjacent support bars 2, and connect the grounding wire of the photovoltaic panel 3 to the support bar 2 at the same time;

[0054] Secondly, the rectangular block 23 is screwed by a wrench to drive the second screw rod 22 to rotate. The rotation of the second screw rod 22 can move downward in the ground rod 9. During the downward movement of the second screw rod 22, the second rotating ring 30 can be driven to move downward. The downward movement of the second rotating ring 30 can push the connecting bar 32 to move outward through the rotating seat 31 until the connecting bar 32 is inserted into the soil, which can further fix the ground rod 9. Then, the second sliding ring 27 is sleeved on the second screw rod 22, and the first pin 28 is inserted into the corresponding first positioning hole 29 to limit the second screw rod 22 to prevent the second screw rod 22 from rotating during use. Then, the connecting ring 26 is sleeved on the second screw rod 22, and finally, the first nut block 25 is screwed on the second screw rod 22 until the first nut block 25 conflicts with the connecting ring 26, and the connecting ring 26 conflicts with the second sliding ring 27, so that the connecting ring 26 and the second sliding ring 27 can be fixed.

[0055] After the grounding lead 16 at one end of the connecting ring 26 is inserted into the clearance opening 38, the socket 14 is placed on the guide seat 10, and the second plug strip 39 is made to correspond to the second plug hole 40, and the socket 14 is pushed to move on the guide seat 10, the second plug strip 39 can be driven to be inserted into the corresponding second plug hole 40, and the grounding rod 9 is further limited until one side of the protective shell 15 abuts against the positioning groove 43, and finally the bolt 42 is passed through the protective shell 15 and is threadedly connected with the second nut block 41, so that the grounding rod 9 and the column 1 can be fixed as a whole, and the column 1 is further strengthened, and the grounding lead 16 is protected at the same time;

[0056] Finally, the other end of the grounding lead 16 is connected to the support bar 2 to form a lightning protection system.

[0057] However, as is well known to those skilled in the art, the working principle and wiring method of the photovoltaic panel 3 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
