Detailed Implementation The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] refer to Figure 1-3 The top-mounted angle-adjustable photovoltaic (PV) support system includes multiple equally spaced front columns 1, rear columns 2, diagonal beams 3, crossbeams 4, PV modules 5, and a synchronous adjustment mechanism 6. The multiple front columns 1 are arranged at equal intervals along the horizontal direction, providing front-end support for the PV array. The multiple rear columns 2 correspond one-to-one with the multiple front columns 1, also equally spaced along the horizontal direction, forming the rear-end support for the PV array. Both the front columns 1 and rear columns 2 can be made of galvanized steel pipes. The height of the front columns 1 can be 0.8m, and the height of the rear columns 2 can be 1.2m, equally spaced along the length of the PV array. The specific height and spacing can be set according to actual installation requirements. The multiple diagonal beams 3 are inclined, with each end... The photovoltaic modules 5 are hinged to the top of the front column 1 and the top of the rear column 2 through a hinged structure of triangular groove plates and bolts, thereby forming an adjustable tilt angle load-bearing frame. Two crossbeams 4 can be welded in parallel to both sides of the top of multiple inclined beams 3 to form a rectangular frame for fixing photovoltaic modules 5. The crossbeams 4 can be made of aluminum alloy profiles. The photovoltaic modules 5 are set on the two crossbeams 4. The photovoltaic modules 5 can realize photoelectric conversion and can be fixed on the crossbeams 4 by pressure blocks. The installation of pressure blocks is existing technology and will not be described in detail here. The synchronous adjustment mechanism 6 is set between the top of multiple rear columns 2 and multiple inclined beams 3, which can realize the synchronous adjustment of the height of multiple inclined beams 3 on multiple rear columns 2, ensuring that the tilt angle of all photovoltaic modules 5 is consistent.

[0018] In some embodiments, the synchronization adjustment mechanism 6 includes an adjustment frame 61, an adjustment rod 62, and multiple synchronization units. The adjustment frame 61 may be an L-shaped steel plate, located on the side of the rear column 2 near the front column 1 to support the adjustment rod 62. It can be welded or bolted. The adjustment rod 62 may be a stainless steel optical shaft, which can be rotatably mounted on multiple adjustment frames 61 via bearing seats. The axis of the adjustment rod 62 is parallel to the arrangement direction of the rear columns 2 to realize the transmission of rotational power. The synchronization units are set corresponding to the rear columns 2, with one synchronization unit for each rear column 2. The upper end is hinged to the inclined beam 3, and the lower end is connected to the adjustment rod 62 through an adjustment assembly, thereby converting the rotational motion of the adjustment rod 62 into the rotation of the inclined beam 3.

[0019] In some embodiments, the synchronization unit includes a lifting groove 63, a lifting rod 64, an adjusting groove 65, and an adjusting assembly. The lifting groove 63 may be a rectangular groove opened at the top of the rear column 2, which can provide vertical lifting guidance for the lifting rod 64. The lifting rod 64 may be a square steel, which can slide along the lifting groove 63. The fitting clearance between the lifting rod 64 and the lifting groove 63 may be 0.3mm, which can ensure smooth sliding and improve the stability of the lifting rod 64 when sliding. The top of the lifting rod 64 can be connected to the inclined beam 3 through a hinged structure of a triangular groove plate and bolts. The adjusting groove 65 may be an elongated hole opened on the side wall of the lifting groove 63, which can provide transmission space for the adjusting assembly. The adjusting assembly is located between the lifting rod 64 and the adjusting rod 62, which can realize the power transmission between the lifting rod 64 and the adjusting rod 62. In some embodiments, the adjustment assembly includes an adjustment gear 66 and a rack 67. The adjustment gear 66 can be fixed to the adjustment rod 62 by a key connection and rotates synchronously with the adjustment rod 62. The rack 67 can be vertically welded to the side wall of the lifting rod 64, corresponding to the position of the adjustment groove 65, and meshing with the adjustment gear 66, thereby converting the rotational motion of the adjustment rod into the lifting motion of the lifting rod 64.

[0020] In some embodiments, a locking bolt 7 is also included. The locking bolt 7 may be a stainless steel bolt that passes through a threaded hole in the side wall of the rear column 2. When tightened, the rear end of the bolt abuts against the side of the lifting rod 64 to rigidly lock the lifting rod 64 and prevent it from loosening after adjustment.

[0021] In some embodiments, the synchronization adjustment mechanism 6 further includes an adjustment handwheel 68, which is fixed to one end of the adjustment rod 62 and may have anti-slip texture on its surface. A single person can rotate the handwheel to drive all synchronization units to move, making it easy for a single person to operate.

[0022] In some embodiments, the synchronous adjustment mechanism 6 further includes a scale marked on the surface of the lifting rod 64, which can intuitively indicate the adjustment height of the lifting rod 64 and facilitate precise adjustment.

[0023] In some embodiments, a load-bearing block 8 is also included; the load-bearing block 8 may be a precast concrete block, which can be fixed to the bottom of the front column 1 and the rear column 2 by pre-embedded bolts to lower the center of gravity and improve the wind load resistance. The load-bearing block 8 and the bottom of the rear column 2 can be hinged by a hinge structure of triangular groove plate and bolts to improve the adjustment range of the tilt angle of the inclined beam 3.

[0024] In some embodiments, an adjusting spring 9 is also included. The adjusting spring 9 may be a compression spring with a diameter of 20 mm and a stiffness of 10 N / mm. The adjusting spring 9 is located between the lifting rod 64 and the bottom wall of the lifting groove 63, and can provide an upward auxiliary elastic force to offset part of the gravity of the photovoltaic module 5, thereby reducing the adjustment resistance and facilitating smooth adjustment.

[0025] The specific working principle is as follows: When it is necessary to adjust the tilt angle of the photovoltaic module 5, loosen all locking bolts 7 to release the rigid lock on the lifting rod 64. The adjusting spring 9 is in a compressed state to provide an upward preload to the lifting rod 64. Determine the target tilt angle according to the local seasonal solar altitude angle (e.g., the optimal tilt angle at 30° North latitude is 15° in summer and 35° in winter), and refer to the scale on the lifting rod 64 to preset the adjustment amount.

[0026] A single person rotates the adjusting handwheel 68, causing the adjusting rod 62 to rotate within the bearing seat of the adjusting frame 61. The rotational power is transmitted along the axis of the adjusting rod to all synchronous units. The adjusting gear 66 on the adjusting rod 62 rotates synchronously with the rod. Through meshing with the rack 67, the rotational motion is converted into the vertical motion of the lifting rod 64. When the adjusting handwheel 68 is rotated counterclockwise, the adjusting gear 66 pushes the rack 67 upward, and the lifting rod 64 slides upward along the lifting groove 63 at the top of the rear column 2, lifting the rear end of the inclined beam 3, increasing the tilt angle of the photovoltaic module 5. When the adjusting handwheel 68 is rotated clockwise, the adjusting gear 66 drives the rack 67 downward, and the lifting rod 64 slides downward under the combined action of the gravity of the photovoltaic module 5 and the adjusting spring 9. The rear end of the inclined beam 3 falls, and the tilt angle decreases. All adjusting gears 66 have the same parameters and are driven by the same adjusting rod 62, ensuring that the displacement of the lifting rod 64 of each synchronous unit is exactly the same, ultimately making the tilt angles of multiple inclined beams 3 the same. The adjusting spring 9 on the bottom wall of the lifting groove 63 always applies an upward auxiliary force to the lifting rod 64, which can offset part of the gravitational force of the photovoltaic module 5 and solve the problem of traditional adjustment being laborious.

[0027] When the scale indication of the lifting rod 64 reaches the set target value, stop rotating the adjusting handwheel 68, tighten the locking bolt 7, so that the end of the locking bolt 7 is firmly pressed against the side of the lifting rod 64 by friction, forming a balance with the elastic force of the adjusting spring 9, preventing the lifting rod 64 from moving down under the gravity of the photovoltaic module 5, thereby locking the tilt angle of the inclined beam 3, preventing the adjusting gear 66 from rotating in the opposite direction, and ensuring the long-term stability of the tilt angle.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
