Description

Technical Field

[0001] This utility model relates to the field of solar panel technology, and in particular to a power supply device that can automatically track sunlight. Background Technology

[0002] A power supply device that can automatically track sunlight is a photovoltaic power generation device that can automatically adjust its angle to track the sun's position in real time. Through the coordinated work of sensors, control algorithms and mechanical drive systems, it maximizes the intensity of sunlight, thereby significantly improving power generation efficiency.

[0003] Currently, most solar tracking devices on the market use fixed brackets or simple single-axis rotating structures, which suffer from problems such as low tracking accuracy, poor adaptability, and weak wind resistance. Traditional solutions rely on heavy mechanical structures or complex control systems, resulting in high costs and difficulty in miniaturization, making them unsuitable for DIY or educational applications. For example, common single-axis tracking devices cannot effectively capture changes in the sun's altitude angle, resulting in limited improvement in power generation efficiency. While dual-axis structures can improve accuracy, they usually require multiple motors, leading to high energy consumption and a bulky structure. In addition, existing base installation methods mostly involve bolt fixing or counterweight ballast, making it difficult to adapt to uneven ground or temporary scenarios, and lacking quick disassembly and assembly functions, which is not conducive to maintenance and expansion. In outdoor environments, strong winds can easily cause the bracket to sway or even overturn, while passive tracking solutions are difficult to implement due to insufficient sensitivity. Therefore, this paper proposes a power supply device that can automatically track sunlight to overcome the above-mentioned defects. Utility Model Content

A lightweight dual-axis tracking mechanism is adopted, combined with a folding linkage and an elastic reset device. Compared with the traditional single-axis or rigid bracket structure, the motor load is reduced by more than 30%, and the overall weight is reduced, making it easier to carry and install.

[0007] As a further description of the above technical solution: the photosensitive sensor is electrically connected to the control circuit board, and the control circuit board is electrically connected to the X-axis motor and the Y-axis motor respectively. Both the X-axis motor and the Y-axis motor can rotate forward and backward.

The bottom and top ends of the connecting rod are connected to the moving block and the base plate through a rotating shaft, so that the moving block inside the base can drive the base plate to move up and down through the outward extending connecting rod.

[0010] As a further description of the above technical solution: the moving block has a through hole from front to back in the middle, and the inner wall of the through hole is provided with an internal thread that matches the pitch and helical direction of the surface of the bidirectional threaded rod. The edge of the moving block is slidably connected to the inner wall at the center of the base. The moving block, which is pierced by the bidirectional threaded rod, can move back and forth through the rotating bidirectional threaded rod.

[0011] As a further description of the above technical solution: the sleeve has a groove running from top to bottom inside, and a through groove connecting the groove is opened at the top of the sleeve. A limiting circular plate is provided between the sliding rod and the compression spring, and the diameter of the groove inside the sleeve matches the diameter of the limiting circular plate. The diameter of the through groove at the top of the sleeve matches the diameter of the slit of the sliding rod. This can provide support when the base plate and its top structure are adjusted in height, avoiding the entire weight of the base plate and its top structure being borne by the connecting rod and the double-threaded rod, and at the same time improving the stability of the base plate and its top structure during height adjustment to a certain extent.

Compared with the traditional single-axis or rigid bracket structure, the motor load is reduced by more than 30%, and the overall weight is reduced, making it easy to carry and install.

[0024] As a further implementation of the above technical solution: the photosensitive sensor 10 is electrically connected to the control circuit board 4, and the control circuit board 4 is electrically connected to the X-axis motor 6 and the Y-axis motor 8 respectively. Both the X-axis motor 6 and the Y-axis motor 8 can rotate forward and backward. By using the photosensitive sensor 10, 360° tracking without blind spots can be achieved with an accuracy of ±1°, which is suitable for scenarios with strict requirements on the illumination angle.

[0025] As a further implementation of the above technical solution: The top front end of the base 1 is connected to the drive motor 12 by bolts. The output end of the drive motor 12 is provided with a bidirectional threaded rod 13. The outer side of the bidirectional threaded rod 13 passes through the interior of the moving block 14 and is screwed with the internal thread inside the moving block 14. The top end of the moving block 14 is connected to the connecting rod 15 through a rotating shaft. The end of the connecting rod 15 away from the moving block 14 is rotatably connected to the middle of the bottom end of the base plate 3 through a rotating shaft. The lower part of the sleeve 2 is welded with a compression spring 17. The top end of the compression spring 17 is fixedly connected to the bottom end of the sliding rod 16. The end of the bidirectional threaded rod 13 away from the motor is rotatably connected to the rear of the base 1, which can drive the base plate 3 to move up and down, adjust the overall height of the base plate 3 and its top structure, and adapt to different installation requirements.

[0026] As a further implementation of the above technical solution: a sliding groove from front to back is provided in the middle of the upper part of the base 1, and the width of the sliding groove matches the cut diameter of the connecting rod 15. The bottom and top ends of the connecting rod 15 are connected to the moving block 14 and the base plate 3 through a rotating shaft, so that the moving block 14 inside the base 1 can drive the base plate 3 to move up and down through the outwardly extending connecting rod 15.

[0029] Working principle:

[0030] When using this utility model, adjust the height of the base plate 3 and its top structure according to installation requirements. Start the drive motor 12 on the front side of the middle inside the base 1. The drive motor 12 drives the bidirectional threaded rod 13 at the output end to rotate. The moving block 14 on the outside of the bidirectional threaded rod 13 drives the connecting rod 15 at the top to move towards the center of the base 1. The overall angle of the connecting rod 15 changes, supporting the base plate 3 upward, thus changing the height of the base plate 3 and its top structure. At the same time, the sliding rods 16 at the four corners of the bottom of the base plate 3 slide upward under the constraint inside the sleeve 2, compressing the spring 1. 7. After rebounding and reaching the set height, the drive motor 12 is turned off, and then the control circuit board 4 is powered on. The photosensitive sensor 10 located at the top of the photovoltaic panel body 11 detects the light source and controls the X-axis motor 6 and Y-axis motor 8 to start through the control circuit board 4. The X-axis motor 6 is fixed in the fixed base 5 and is used to adjust the lateral displacement of the movable base 7 and all structures above it, while the Y-axis motor 8 is fixed inside the movable base 7 and is used to adjust the longitudinal displacement of the photovoltaic panel body 11 at the rear end of the mounting plate 9 and the photosensitive sensor 10 at the top. It is suitable for scenarios with strict requirements on the light angle.
