[0027] As shown in the accompanying Figure 1 , the accompanying Figure 2 , and the accompanying Figure 3As shown, a hydraulically driven, manually adjustable photovoltaic bracket includes a column 5, a bearing 7, and a main shaft 9. The bearing 7 is disposed at one end of the column 5, and the main shaft 9 is rotatably disposed within the bearing 7. The bracket also includes a hydraulic telescopic rod 6, a hand-cranked hydraulic pump 1, a first mounting plate 8, and a second mounting plate 4. The first mounting plate 8 is disposed on the main shaft 9, and the second mounting plate 4 is disposed at one end of the column 5. The two ends of the column 5 are the bearing 7 and the second mounting plate 4, respectively. The two ends of the hydraulic telescopic rod 6 are hinged to the first mounting plate 8 and the second mounting plate 4, respectively. The hand-cranked hydraulic pump 1 is connected to the hydraulic telescopic rod 6 through a pipe.

[0028] In this type of hydraulically driven, manually adjustable photovoltaic (PV) bracket, the PV panel is mounted on a main shaft 9, which is rotatably mounted on a bearing 7. The main shaft 9 can rotate relative to the bearing 7, and when the main shaft 9 rotates relative to the bearing 7, the PV panel rotates relative to the column 5. In this PV bracket, the rotation of the main shaft 9 is achieved by the extension and retraction of a hydraulic telescopic rod 6, which is controlled by a hand-cranked hydraulic pump 1. When the user cranks the handle 101 on the hand-cranked hydraulic pump 1, the hydraulic telescopic rod 6 extends or retracts. This bracket uses the hand-cranked hydraulic pump 1 and the hydraulic telescopic rod 6 to control the rotation of the main shaft 9; cranking the hand-cranked hydraulic pump 1 requires less effort than cranking a worm gear.

[0029] Specifically, in this support structure, a ball valve is installed between the interface of the hydraulic telescopic rod and the pipeline to improve safety.

[0030] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes a photovoltaic panel, which is fixed on the main shaft 9.

[0031] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes purlins 10, which are fixed to the main shaft 9 and perpendicular to the main shaft 9. The photovoltaic panel is fixed to the purlins 10.

[0032] The function of purlin 10 is to install photovoltaic panels.

[0033] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes a pressure block 11, which is disposed between two adjacent photovoltaic panels.

[0034] The function of the pressure block 11 is twofold: to separate two adjacent photovoltaic panels and to hold the photovoltaic panels in place.

[0035] As attached Figure 1 Appendix Figure 2 and appendix Figure 3As shown, it also includes a base column 2, which is located at one end of the second mounting plate 4, and the upright column 5 and the base column 2 are located on the two sides of the second mounting plate 4 respectively, with the base column 2 and the upright column 5 on the same straight line.

[0036] The base column 2 supports the upright column 5. There are multiple upright columns 5, each equipped with a bearing 7. Each upright column 5 is connected to the base column 2 via a second mounting plate 4. To improve the wind resistance and stability of the entire photovoltaic support system, hydraulic dampers 12 are installed between some purlins 10 and the second mounting plate 4. One end of the hydraulic damper 12 is hinged to the purlin 10, and the other end is hinged to the second mounting plate 4. The characteristics of the hydraulic damper 12 ensure the stability between the main shaft 9 and the upright column 5, preventing the main shaft 9 from being easily rotated by the wind.

[0037] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the hand-cranked hydraulic pump 1 is equipped with a rocker arm.

[0038] Shaking the rocker arm in different directions can control the extension or retraction of the hydraulic telescopic rod 6.
