The lower end of the positioning rod 342 is threadedly connected to the sliding rod 32. The positioning rod 342 abuts against the bottom surface of the guide groove 330 by the elastic force of the spring 343. The positioning rod 342 is always held in place by the spring 343 in a compressed state.

[0045] like Figure 5 As shown, the rotating adjustment handwheel 5 is detachably snapped onto the rotating adjustment rod 13. The rotating locking device 6 includes a locking rod 61 and a locking plate 62. Several locking holes 130 are provided in the circumference of the rotating adjustment rod 13, and the locking rod 61 is snapped into one of the locking holes 130.

[0046] The two ends of the rotating adjusting rod 13 are rotatably connected to the bottom connecting seat 11, and one end of the rod is provided with a rotating adjusting handwheel 5 and a rotating locking device 6. The rotating adjusting handwheel 5 is detachably locked onto the rotating adjusting rod 13 and is used to manually adjust the rotation angle of the rotating adjusting rod 13 to adjust the position of the adjusting device 3.

[0047] The rotating locking device 6 includes a locking rod 61 and a locking plate 62. The rotating adjusting rod 13 has a ring of locking holes 130 around its circumference. There can be 6-12 locking holes, spaced 30-60 degrees apart. Each rotation of a locking hole 130 can adjust the rotation angle of the rotating adjusting rod 13. The locking rod 61 can be inserted into the locking hole 130 to fix the adjusted angle.

[0048] like Figure 5-7 As shown, the lower end of the adjusting connecting rod 31 is connected to the rotating adjusting rod 13, and the upper end is fixed to the sliding rod 32; the sliding rod 32 is slidably engaged in the adjusting guide rod 33 at the bottom of the photovoltaic mounting plate 2; the adjusting guide rod 33 has a guide groove 330 inside, which is used to guide the movement of the sliding rod 32.

[0049] Example 2, based on Example 1, such as Figures 6-7 As shown, in order to fix the relative position between the sliding rod 32 and the adjusting guide rod 33, this utility model provides a positioning device 34, including a U-shaped positioning plate 341, a positioning rod 342, and a spring 343. One end of the positioning rod 342 is engaged with the U-shaped positioning plate 341, and the other end passes through the sliding rod 32 and abuts against the bottom surface of the guide groove 330. The spring 343 is sleeved on the positioning rod 342 to provide elastic pressure, ensuring that the sliding rod 32 remains stable after adjustment and preventing loosening.

[0050] The lower end of the positioning rod 342 is threaded onto the sliding rod 32 and finally abuts against the guide rod 33, keeping the sliding rod 32 and the guide rod 33 fixed. At the same time, the spring 343 of the positioning device 34 provides continuous pressure to ensure that the sliding rod 32 remains stable after adjustment and to avoid angular deviation due to wind or vibration.

[0051] Installation method: Fix the bottom connecting seat 11 to the roof with bolts 1224; snap the main support frame 12 onto the fixing seat 1123; fix the photovoltaic mounting plate 2 onto the connecting shaft 121 with clamping bushing 122; connect the adjustment device 3 to ensure that the sliding rod 32 can slide smoothly in the adjustment guide rod 33; adjust the angle of the photovoltaic panel 4 by rotating the adjustment handwheel 5; and fix the final angle of the photovoltaic panel 4 using the locking device 6 and the connecting adjustment device 3.

[0052] Working principle: Rotating the adjustment handwheel 5 drives the adjustment rod 13 to rotate. The adjustment rod 13 pushes the sliding rod 32 to slide along the adjustment guide rod 33 through the adjustment connecting rod 31. The movement of the sliding rod 32 drives the photovoltaic mounting plate 2 to rotate around the connecting shaft 121, realizing the dynamic adjustment of the angle of the photovoltaic plate 4. After adjusting to a suitable angle, the locking rod 61 is inserted into the corresponding locking hole 130 to fix the adjustment rod 13. Then, the positioning rod 342 is used to fix the relative position of the adjustment guide rod 33 and the sliding rod 32 to determine the angle of the photovoltaic plate 4.

[0053] This utility model has a simple overall structure and is easy to adjust, making it suitable for various sloping or flat rooftops. Its modular design makes it easy to transport, install, and maintain. By incorporating adjustment, positioning, and rotation locking devices, the angle of the photovoltaic panels can be adjusted and locked to ensure the optimal light angle and improve power generation efficiency. The rubber shock-absorbing pads enhance the photovoltaic panels' shock resistance, preventing them from loosening or falling off due to wind vibrations, thus extending their service life.

[0054] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
