[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a windproof device for a photovoltaic power station system, including a base 1, side plates 2 fixedly installed on the upper two sides of the base 1, a connecting shaft 3 fixedly installed on the inner side of the side plates 2, a windproof wall 4 movably sleeved on the outer side of the connecting shaft 3, a top plate 5 fixedly installed on the front top of the windproof wall 4, a bottom plate 6 fixedly installed on the front bottom of the windproof wall 4, an elliptical column 7 rotatably installed on the top of the bottom plate 6, windproof cloth 8 fixedly installed on both sides of the front end of the windproof wall 4, the elliptical column 7 being located inside the windproof cloth 8, a rectangular plate 11 fixedly installed on the upper part of the base 1, a groove 12 being formed on the upper part of the rectangular plate 11, the groove 12 corresponding to the bottom of the windproof wall 4.

[0024] First, adjust the tilt of the windbreak wall 4 according to the wind speed. Then, start the servo motor 19, which drives the screw 14 to rotate. The screw 14 drives the block 15 to move inward, thereby tilting the windbreak wall 4 through the transmission plate 20. Then, start the servo motor 31, which drives the elliptical cylinder 7 to rotate. The rotation of the elliptical cylinder 7 compresses the inside of the windproof cloth 8, causing the windproof cloth 8 to deform. This allows the windproof cloth 8 to block the strong wind while relieving the force, making it easy to use.

[0025] By activating servo motor 19, the windbreak wall 4 is tilted via transmission plate 20. Then, servo motor 31 is activated, causing the windproof cloth 8 to deform. This windproof cloth 8 blocks the strong wind while simultaneously dissipating the force. Compared with traditional windproof devices for photovoltaic power station systems, this windproof device dissipates the strong wind through the windproof cloth 8, effectively reducing the impact force of the wind on the front of the windbreak wall 4, improving the overall stability, and making it easier to use.

[0026] The base 1 has a slot 17 on its right side and a slot 18 above it. The base 1 has a plate 21 fixedly installed on its left side. The plate 21 has a movable groove 22 inside it. A ramp 23 is movably installed inside the movable groove 22. A telescopic spring 24 is elastically installed between the inner side of the movable groove 22 and the inner side of the ramp 23.

[0027] Multiple bases 1 are arranged in a row, and then the insert plate 21 is inserted into the slot 17. The inclined block 23 is compressed by the base 1 and shrinks into the limiting groove 25. The inclined block 23 compresses the telescopic spring 24, causing the telescopic spring 24 to deform. After the insert plate 21 is fully inserted into the slot 17, the telescopic spring 24 releases its elastic potential energy and pushes the inclined block 23 outward, thereby assembling multiple bases 1 for easy use.

[0028] By arranging multiple bases 1 in a row and then inserting the insert plate 21 into the slot 17, once the insert plate 21 is inserted into the slot 17, the telescopic spring 24 releases its elastic potential energy to push the inclined block 23 outward, thereby assembling multiple bases 1. Compared with traditional photovoltaic power station system windproof devices, this photovoltaic power station system windproof device assembles multiple bases 1 by inserting the insert plate 21 into the slot 17, making it easier to use.

[0029] The base 1 has a horizontal groove 13 on its upper part. A screw 14 is rotatably installed inside the horizontal groove 13. A movable block 30 is threaded onto the outer side of the screw 14. Two square blocks 15 are fixedly installed on both sides above the movable block 30. A connecting rod 16 is fixedly installed between the inner sides of the two square blocks 15. A square plate 9 is fixedly installed on the rear side of the windbreak wall 4. A connecting rod 10 is fixedly installed on the inner side of the square plate 9. The connecting rod 10 and the connecting rod 16 are connected by transmission plate 20.

[0030] Start the servo motor 19, which drives the screw 14 to rotate. The screw 14 drives the block 15 to move inward. The block 15 drives the transmission plate 20 to move through the connecting rod 16, which in turn drives the connecting rod 10 to move. The connecting rod 10 then drives the windbreak wall 4 to tilt through the square plate 9.

[0031] Servo motor 2 31 is fixedly installed at the bottom of the base plate 6, and the output end of servo motor 2 31 is fixedly connected to the bottom of the elliptical cylinder 7.

[0032] Start the servo motor 31, which drives the elliptical cylinder 7 to rotate. The rotation of the elliptical cylinder 7 compresses the inside of the windproof cloth 8, causing the windproof cloth 8 to deform. This allows the windproof cloth 8 to block the strong wind while simultaneously relieving the force.

[0033] Among them, an arc-shaped groove 27 is provided on the inner side of the side plate 2, an arc-shaped block 28 is fixedly installed inside the arc-shaped groove 27, and an arc-shaped spring 29 is elastically installed between the inner side of the arc-shaped block 28 and the inner side of the arc-shaped groove 27.

[0034] The windbreak wall 4 rotates, causing the arc-shaped block 28 to move inside the arc-shaped groove 27, thereby compressing the arc-shaped spring 29 and causing the arc-shaped spring 29 to deform.

[0035] Among them, the movable groove 22 has limit grooves 25 on both sides, and the bottom sides of the inclined block 23 are fixedly installed with limit blocks 26 located inside the limit grooves 25.

[0036] The inclined block 23 moves inside the movable groove 22, causing the limiting block 26 to move inside the limiting groove 25, thereby limiting the inclined block 23.

[0037] The base 1 has a servo motor 19 fixedly mounted on its rear side, and the output end of the servo motor 19 is fixedly connected to the front end of the screw 14.

[0038] Start the servo motor 19, which drives the screw 14 to rotate. The screw 14 drives the block 15 to move inward, thereby causing the windproof wall 4 to tilt through the transmission plate 20.

[0039] Working principle and usage process of this utility model:

[0040] First, adjust the tilt of the windbreak wall 4 according to the wind speed. Then, start the servo motor 19, which drives the screw 14 to rotate. The screw 14 drives the block 15 to move inward, thereby tilting the windbreak wall 4 through the transmission plate 20. Then, start the servo motor 31, which drives the elliptical cylinder 7 to rotate. The rotation of the elliptical cylinder 7 compresses the inside of the windproof cloth 8, causing the windproof cloth 8 to deform. This allows the windproof cloth 8 to block the strong wind while relieving the force, making it easy to use.

[0041] Multiple bases 1 are arranged in a row, and then the insert plate 21 is inserted into the slot 17. The inclined block 23 is compressed by the base 1 and shrinks into the limiting groove 25. The inclined block 23 compresses the telescopic spring 24, causing the telescopic spring 24 to deform. After the insert plate 21 is fully inserted into the slot 17, the telescopic spring 24 releases its elastic potential energy and pushes the inclined block 23 outward, thereby assembling multiple bases 1 for easy use.
