DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to Figure 1 , 2 A tracking photovoltaic bracket provided in an embodiment of the present invention includes a base 1 and a photovoltaic panel 2 thereon, wherein the photovoltaic panel 2 is connected to a support frame 3 via a pitch angle adjustment mechanism for adjusting the pitch angle of the photovoltaic panel 2; connecting rod assemblies are provided at both ends of the support frame 3, and the connecting rod assemblies are connected to the base 1 via a driving component for adjusting the inclination angle of the support frame 3.

[0026] In a specific embodiment of the present invention, Figure 1 As shown, the pitch angle adjustment mechanism includes a first motor 4, a screw rod 5, a slider 6 and a support rod 7. The support frame 3 is a frame structure. The rear end of the photovoltaic panel 2 is rotatably connected to the rear side frame of the support frame 3. The first motor 4 is fixedly connected to the left side frame and / or the right side frame of the support frame 3 through a fixing rod 8. One end of the screw rod 5 is coaxially fixed to the output shaft of the first motor 4, and the other end of the screw rod 5 is rotatably matched with the front side frame of the support frame 3; the slider 6 is rotatably matched with the screw rod 5, and the slider 6 is connected to the bottom of the photovoltaic panel 2 through the support rod 7. Among them, the front end of the screw rod is rotatably matched with the support frame through a bearing. The first motor drives the screw rod to rotate, thereby driving the slider to move along the screw rod. The slider drives the front end of the photovoltaic panel to rise and fall through the support rod, thereby realizing the pitch angle change of the photovoltaic panel.

[0027] When making specific Figure 1 , 2 As shown, the photovoltaic panel 2 is arranged on a fixing frame 9 around which a plurality of purlins 12 are arranged at intervals at the bottom of the fixing frame 9; the rear end of the photovoltaic panel 2 is rotatably matched with a rotating shaft 11 through a steel pipe 10, and the rotating shaft 11 is arranged at both ends of the purlin 12 at the rear end of the fixing frame 9. This structure facilitates the fixing frame on which the photovoltaic panel is installed to rotate around the rotating shaft to adjust the pitch angle.

[0028] As a preferred solution, Figure 2As shown, the connecting rod assembly includes four groups of planar connecting rod mechanisms, which are divided into two groups and arranged below the two ends of the support frame 3. The two groups of planar connecting rod mechanisms at the front end and the rear end of the support frame 3 are symmetrically arranged. The four groups of planar connecting rod mechanisms are all four-link mechanisms composed of three fixed rods 13 and one movable rod 14. The three fixed rods 13 form a tripod. The top angle of the tripod is rotatably connected with the support frame 3. The bottom angle of one side of the tripod is rotatably connected with the sliding support 15, and the bottom angle of the other side is rotatably connected with the fixed support 16. The sliding support 15 can slide along the slide groove 17 on the base 1 and is driven by the driving component. The fixed supports 16 of the two groups of planar connecting rod mechanisms at the same end of the support frame 3 are arranged adjacent to each other. The driving component drives the sliding support to move in and out of the slide groove, thereby driving the lifting and lowering of the photovoltaic panel on this side, and then the sliding support on the other side of the photovoltaic panel is passively moved along the slide groove to achieve the left and right tilting of the support frame.

[0029] In a specific embodiment of the present invention, Figure 1 , 2 As shown, the two sets of planar linkage mechanisms at the same end of the support frame 3 are divided into an active linkage mechanism 18 and a passive linkage mechanism 19. The sliding support 15 at the bottom of the movable rod 14 in the active linkage mechanism 18 is driven by the driving component to slide along the slide groove 17 on the base 1, and the sliding support 15 at the bottom of the movable rod 14 in the passive linkage mechanism 19 can passively slide along the slide groove 17 on the base 1. The driving component is arranged inside the base 1, and the driving component includes a second motor 20, a driving gear 21, a rack 22 and a transmission rod 23. The output end of the second motor 20 is coaxially fixed with the driving gear 21, and the driving gear 21 is meshed with the rack 22; one end of the rack 22 is fixed to the lower end of the transmission rod 23; the upper end of the transmission rod 23 is connected to the sliding support 15 at the bottom of the movable rod 14 in the active linkage mechanism 18. Driven by the second motor 20, the sliding support 15 at the bottom of the movable rod 14 in the active link mechanism 18 slides along the slide groove 17 on the base 1, and the support frame 3 tilts to the other side. The sliding support 15 at the bottom of the movable rod 14 in the passive link mechanism 19 on the other side of the support frame 3 slides passively along the slide groove 17 on the base 1. Figure 2 When the middle active gear rotates clockwise, the rack drives the transmission rod and the sliding support in the active connecting rod mechanism to move to the right, driving the left side of the photovoltaic panel to rise and the right side to fall, and then drives the sliding support in the passive connecting rod mechanism to slide to the right along the slide groove; conversely, the active gear rotates counterclockwise to drive the photovoltaic panel to tilt to the left.

[0030] Further optimize the above technical solution, such as Figure 1As shown, the bottom of the movable rod 14 in the active linkage mechanism 18 on the same side of the support frame 3 is connected through the first linkage 24, and the bottom of the movable rod 14 in the passive linkage mechanism 19 on the same side is connected through the second linkage 25, the second motor 20 and the active gear 21 are arranged between the first linkage 24 and the second linkage 25, the rack 22 is correspondingly arranged between the two ends of the support frame 3, and the upper end of the transmission rod 23 is connected to the first linkage 24. The use of this structure can simplify the equipment, and the tilt angle adjustment of the photovoltaic panel can be driven by a second motor.

[0031] In a specific embodiment of the present invention, Figure 3-5 As shown, the photovoltaic panels 2 are divided into several pieces, and the several photovoltaic panels 2 are arranged in multiple rows and columns on the base 1. The active connecting rod mechanisms 18 below the photovoltaic panels 2 in the same row above the base 1 are all driven by driving components. More than two passive gears 26 are also provided in the base 1. The active gear 21 is arranged in the middle of the rack 22, and the passive gears 26 are arranged at intervals on both sides of the active gear 21; the sliding supports 15 at the bottom of the movable rod 14 in the active connecting rod mechanisms 18 in the same row are all connected to the rack 22. Among them, the passive gear 26 is arranged on the support column 27, and the gear shaft of the passive gear 26 is rotatably matched with the support column 27 through a bearing. Similarly, the overall structure of the equipment is further simplified by adopting this structure. The tilt angle adjustment of several photovoltaic panels can be driven by a set of driving components.

[0032] As a preferred structure, Figure 3 As shown, the sliding supports 15 at the bottom of the active rod 14 in the active linkage mechanism 18 under the same column of photovoltaic panels 2 are all connected through the first linkage 24, and the sliding supports 15 at the bottom of the active rod 14 in the passive linkage mechanism 19 are all connected through the second linkage 25; the rack 22 of the driving component is arranged in the middle position of the base 1; the screw rod 5 under the same column of photovoltaic panels 2 is coaxially connected through the connecting shaft 28, and the first motor 4 is arranged under each photovoltaic panel 2 in the first row. Each photovoltaic panel can drive the pitch angle adjustment of the entire column of photovoltaic panels with only one first motor. The photovoltaic panels in this embodiment are arranged in three rows and three columns, and the first motor is only installed under the photovoltaic panels in row A. The first motor does not need to be installed under rows B and C. When working, only the three first motors in row A need to be controlled to move synchronously to synchronously drive the pitch angle adjustment of all photovoltaic panels; at the same time, the second motor is arranged below the middle of row B, and the left and right tilt angles of all photovoltaic panels can be driven to be adjusted synchronously by using one second motor. The integration of the tilt angle of the photovoltaic panel is achieved by coordinating the movement of the first motor and the second motor, so that it reaches the optimal tilt angle relative to the sun.

[0033] In summary, the present invention has the advantages of simple and compact structure, convenient processing and manufacturing, flexible and convenient operation, adopts a base to provide support for the connecting rod assembly, and utilizes the coordinated cooperation of the first motor and the second motor to achieve a certain inclination angle between the photovoltaic panel and the horizontal plane, so that it can rotate with the sun, thereby obtaining solar radiation to the greatest extent, expanding the time range of the optimal inclination angle of photovoltaic power generation, and improving the utilization rate of solar energy.

[0034] In the above description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed above.
