[0030] A slide groove 12 extending along the axial direction is provided on one side of the vertical pole 1, and a certain pulley 4 is provided at the upper end of the vertical pole 1. It can be understood that the fixed pulley 4 can be welded to the top of the vertical pole 1. The diameter size of the fixed pulley 4 depends on the required torque and bearing capacity. Therefore, it can be selected according to the actual structure and weight of the photovoltaic panel 2. This embodiment is not specifically limited here; a track 31 and a pulling member 5 are provided on the photovoltaic bracket 3. The photovoltaic bracket 3 can be slidably matched with the vertical pole 1 through the track 31 and the slide groove 12, so that the height of the photovoltaic bracket 3 relative to the vertical pole 1 can be adjusted according to needs. The free end of the pulling member 5 bypasses the fixed pulley 4 and extends to a lower position close to the vertical pole 1. In this embodiment, the height of the lower position from the ground should be close to 180-200cm, so as to avoid children from accidentally touching it, and it can also be used by adults without borrowing When in use, the pulling member 5 can drive the photovoltaic bracket 3 to move axially along the vertical pole 1 when it moves (contracts or extends) with the fixed pulley 4 as the fulcrum, thereby adjusting the height of the photovoltaic panel 2 relative to the vertical pole 1 to meet the needs of normal maintenance and cleaning. That is, in this embodiment, by arranging the slide groove 12, the fixed pulley 4 and the pulling member 5 on the vertical pole 1, it is possible to perform normal maintenance and cleaning operations without the aid of additional climbing equipment, and only the height of the photovoltaic panel 2 needs to be lowered, thereby increasing the convenience and flexibility of the use of the solar power supply device. At the same time, when necessary, the height of the solar panel can be adjusted as needed to maintain the solar panel more efficiently. In this embodiment, the pulling member 5 is preferably a pull rope structure composed of aluminum alloy or galvanized steel, and its surface can be coated with a corrosion-resistant and anti-oxidation coating.

[0031] The free end of the pulling member 5, that is, the end close to the bottom of the vertical pole 1, is connected to a counterweight 6, the weight of which is greater than the sum of the weights of the photovoltaic bracket 3 and the photovoltaic panel 2, and a locking member is provided on the vertical pole 1, which can fix the counterweight 6 at a specified position. In this embodiment, the counterweight 6 and the photovoltaic bracket 3 form a balanced structure, and the photovoltaic panel 2 can be pulled and balanced and fixed by the counterweight 6 to ensure the stability of the photovoltaic bracket 3. In other embodiments of the utility model, the free end of the pulling member 5 can also be fixed to the specified position of the vertical pole 1 by a fixing member such as a lock buckle or a lock ring.

[0032] A limiting groove 13 capable of limiting the position of the counterweight 6 is provided on the vertical pole 1, and a limiting block which can be located in the limiting groove 13 is provided on the counterweight 6.

On the other hand, the safety of the use of the counterweight 6 can be improved.

[0033] In this embodiment, the locking member can be a locking bolt 8, and a locking screw hole is provided on the vertical pole 1, and the locking screw hole passes through the limiting groove 13. When in use, tightening the locking bolt 8 can make its end contact with the limiting block on the counterweight 6 and clamp it and lock it in the limiting groove 13; in other embodiments of the utility model, the locking member can also be a structure such as a clamp.

[0034] In this embodiment, if necessary, a locking piece is also provided on the slide groove 12 where the photovoltaic bracket 3 is located, so that the photovoltaic bracket 3 can be strengthened and fixed, the bearing load of the pulling piece 5 can be reduced, and the service life and safety of the pulling piece 5 can be improved.

[0035] In this embodiment, the slide groove 12 and the limit groove 13 are preferably both "mortar" shaped structures, and at the same time, the track 31 set on the photovoltaic frame and the limit block on the counterweight block 6 are both T-shaped structures, such as Figure 4-5 As shown, this can not only ensure effective and safe sliding, but also achieve limiting, thereby preventing the rail 31 or the limiting block from escaping from the sliding groove 12 or the limiting groove 13.

[0036] Elastic buffer members 9 are respectively provided at the upper end of the slide groove 12 and the bottom end of the limit groove 13. Figure 6 As shown, the elastic buffer 9 can be a compression spring, which can limit the speed of the photovoltaic panel 2 or the counterweight 6 when it reaches the limit position. On the one hand, it improves the safety of use, and on the other hand, it avoids damage caused by hard contact between the photovoltaic panel 2 or the counterweight 6 and the vertical pole 1.

[0037] A guardrail 7 is provided below the upright pole 1. Figure 6 As shown, the guardrail 7 is located on one side of the counterweight 6 to enclose the counterweight 6 inside. In this embodiment, the guardrail 7 can be a baffle structure or a frame structure, so as to shield the counterweight 6 from contact with the operator when it reaches the bottom. The guardrail 7 can be used to isolate the counterweight 6 from the operator to avoid injury. If necessary, a warning sign can be posted on the column or guardrail 7. It can be understood that the height of the guardrail 7 should be based on not affecting the normal locking and fixing of the counterweight 6.

The diversion groove 11 can transport rainwater to a position far away from the vertical pole 1 to prevent rainwater from soaking the soil at the installation position of the vertical pole, causing the soil to become loose and then causing the vertical pole to tilt or fall; the protective cover 10 can be welded or screwed to the top of the vertical pole 1. In this embodiment, a fixing ear plate is preferably provided at the bottom of the protective cover 10, and it is fixed to the upper end of the vertical pole 1 by the fixing ear plate.

The above-mentioned sensing data displayed by the monitoring terminal can be viewed online by farmers at any time. The specific model and type of each sensor can be selected according to actual needs, and this embodiment does not limit it in detail; the farmland image acquisition unit camera 15 is used to obtain image data of crops in the field and send it wirelessly to the monitoring terminal via the controller.
