[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A photovoltaic device based on a dual-axis tracking bracket, see [link / reference]. Figures 1 to 5 The system includes a support frame 3, which is fixedly connected to the top of the annular turntable 2. A transmission rod 301 is rotatably connected between the left and right side walls of the support frame 3. Two active bevel gears 302 are fixedly sleeved on the surface of the transmission rod 301. The two active bevel gears 302 mesh with the first driven bevel gear 401 and the second driven bevel gear 601, respectively. The transmission rod 301 drives the two active bevel gears 302 to rotate, which in turn drives the transmission structures on the upper and lower sides to rotate, thereby rotating the annular turntable 2 and raising the mounting frame 12. This allows for adjustment of the rotation direction and tilt angle to adapt to different lighting environments.

[0023] Specifically, a synchronizing rod 6 is rotatably connected to the surface of the horizontal plate 303 through a bearing seat, and the outer surface of the synchronizing rod 6 is fixedly connected to the inner ring of the bearing seat. The outer ring of the bearing seat is fixedly connected to the inner wall of the horizontal plate 303. A second driven bevel gear 601 is fixedly connected to both the upper and lower ends of the synchronizing rod 6. The upper driven bevel gear 601 meshes with the driving bevel gear 602. The driving bevel gear 602 is fixedly sleeved on the outer surface of the rotating rod 7. The upper and lower driven bevel gears 601 rotate at the same speed. The upper driven bevel gear drives the driving bevel gear 602 and the rotating rod 7 to rotate. The rotating rod 7 then drives the lead screw 9 to rotate, which allows the moving block 10 and the support rod 11 to push the mounting frame 12 to change its angle.

[0024] Furthermore, such as Figure 2 As shown, a side frame 201 is fixedly connected to the top of the annular turntable 2 on one side of the support frame 3. A sleeve rod 4 is rotatably connected to the surface of the side frame 201 via a bearing seat. The outer surface of the sleeve rod 4 is fixedly connected to the inner ring of the bearing seat, and the outer ring of the bearing seat is fixedly connected to the inner wall of the side frame 201. A telescopic frame 402 is telescopically sleeved at the bottom end of the sleeve rod 4. A rotating groove 5 is rotatably connected to the surface of the annular turntable 2 directly below the first telescopic frame 402. When the first telescopic frame 402 descends and extends into the first rotating groove 5, the sleeve rod 402... Rod 4 and telescopic frame 402 can drive the first rotating groove 5 to rotate; a horizontal plate 303 is fixedly connected to the side wall of the support frame 3 above the transmission rod 301, and a rotating rod 7 is rotatably connected to the inner left side wall of the support frame 3 above the horizontal plate 303. The right end of the rotating rod 7 is telescopically sleeved with a second telescopic frame 701. The right end of the second telescopic frame 701 is provided with a second rotating groove 8. When the second telescopic frame 701 extends laterally into the second rotating groove 8, the rotating rod 7 can drive the second rotating groove 8 and the lead screw 9 to rotate, thereby allowing the moving block 10 to move laterally.

[0025] It should be noted that the inner walls of both the first rotating trough 5 and the second rotating trough 8 are equipped with a lever 501. The lever 501 can make the first telescopic frame 402 or the second telescopic frame 701 contact the lever 501 after being inserted, and drive the first rotating trough 5 and the second rotating trough 8 to rotate respectively.

[0026] It is worth noting that, such as Figure 3As shown, a lead screw 9 is rotatably connected to the inner right side wall of the support frame 3 corresponding to the horizontal height of the rotating rod 7. A moving block 10 passes through the surface of the lead screw 9 and is threadedly connected to the moving block 10. The top end of the moving block 10 is rotatably connected to the bottom end of the support rod 11 through a hinge seat. The top end of the support rod 11 is transversely penetrated by a round rod 111, and the round rod 111 is rotatably connected to the support rod 11 through a bearing seat. The two ends of the round rod 111 are respectively rotatably connected to the side walls of the two protruding parts at the bottom of the mounting frame 12. After the lead screw 9 rotates, the moving block 10 moves to the left, thereby causing the upper support rod 11 and the round rod 111 to push the mounting frame 12 to increase its tilt angle, thus allowing the photovoltaic equipment to adapt to different light environments and improving the practicality of the device.

[0027] In practical use, the annular turntable 2 is rotatably connected to the top surface of the base 1. A central column 101 is fixedly connected to the center of the top of the base 1. The central column 101 and the outer edge of the first rotating groove 5 are both provided with toothed grooves that mesh with each other. Since the central column 101 remains fixed, and the first rotating groove 5 is also located on the surface of the annular turntable 2 and only has the ability to rotate, when the first rotating groove 5 rotates, the annular turntable 2 will rotate, causing the mounting bracket 12 above to change its orientation to adapt to the direction of light.

[0028] It is worth noting that, such as Figure 4 and Figure 5 As shown, a driven bevel gear 401 is fixedly connected to the top of the sleeve rod 4; a fixing plate 403 is fixedly connected to the outer surface of the sleeve rod 4; an electric actuator 404 is fixedly connected between the bottom of the fixing plate 403 and the telescopic frame 402; a second fixing plate 702 is fixedly connected to the outer surface of the rotating rod 7; a second electric actuator 703 is fixedly connected between the second fixing rod and the second telescopic frame 701; the electric actuator 404 drives the first telescopic frame 402 and the second telescopic frame 701 to perform telescopic operations, so that the first rotating groove 5 and the second rotating groove 8 are temporarily separated from the overall transmission structure, thereby facilitating the individual adjustment of the orientation and tilt angle of the mounting frame 12.

[0029] It is worth describing that the top of the mounting frame 12 is fixedly connected to the photovoltaic device body 13 and the light tracking sensor 14. The outer wall of the support frame 3 corresponding to the horizontal height of the transmission rod 301 is fixedly connected to the servo motor 304. The output end of the transmission shaft of the servo motor 304 is fixedly connected to one end of the transmission rod 301. The photovoltaic device body 13 includes photovoltaic panels and corresponding inverter and controller components, thereby converting solar energy into electrical energy for easy use, powering the light tracking sensor 14 and the servo motor 304, and facilitating the adjustment of the orientation and tilt angle of the mounting frame 12 to track the direction of light at any time.

[0030] Working principle: The servo motor 304 drives the transmission rod to rotate, and the two active bevel gears 302 on the transmission rod drive the first driven bevel gear 401 and the second driven bevel gear 601 to rotate respectively. The first driven bevel gear 401 drives the first telescopic frame 402 to rotate through the sleeve rod 4. The first telescopic frame 402 extends into the first rotating slot 5 and drives it to rotate, thereby changing the orientation of the photovoltaic equipment. At the same time, the second driven bevel gear 601 drives the upper second driven bevel gear 601 to rotate through the synchronizing rod 6, which in turn drives the drive bevel gear 602 and the rotating rod 7 to rotate. The rotating rod 7 drives the lead screw 9 to rotate, and the moving block 10 moves laterally on the lead screw 9, pushing the mounting frame 12 to change the tilt angle through the support rod 11 and the round rod 111. In addition, the first electric actuator 404 and the second electric actuator 703 can respectively drive the first telescopic frame 402 and the second telescopic frame 701 to extend and retract, so that the first rotating trough 5 and the second rotating trough 8 are temporarily separated from the transmission structure, which facilitates the individual adjustment of the orientation and tilt angle of the photovoltaic equipment. This gives the device the ability to adjust independently, adapts to the independent adjustment needs under different lighting conditions, and improves the practicality of the device.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
