Description

Technical Field

[0001] The present application relates to the technical field of solar panels, and in particular to an automatic tracking solar panel. Background Art

[0002] Solar cells are thin sheets of photovoltaic semiconductors that use sunlight to generate electricity directly. They are also called "solar chips" or "photovoltaic cells". As long as they are illuminated under certain illumination conditions, they can instantly output voltage and generate current in the presence of a circuit. In physics, this is called solar photovoltaics, or photovoltaics for short. The installation of photovoltaic panels usually requires the help of a mounting frame. Existing mounting frames are usually fixed frame structures to save costs.

[0003] Although the fixed frame structure is low-cost and easy to construct, its shape will not change during subsequent use after the installation angle is fixed. Although the subsequent maintenance cost is low, it also limits the conversion efficiency of the solar panel. Therefore, some solar panels will use a movable bracket structure to adapt to the changes in the sun's position and increase the power generation efficiency of the solar panel. Therefore, in order to solve the above problems, the present application provides an automatic tracking solar panel.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 - Figure 5This application is described in further detail.

[0022] Embodiment 1:

[0023] Reference Figure 1 - Figure 5 An automatic tracking solar panel includes a solar panel 1. The bottom end of the solar panel 1 is rotatably connected to a bracket 2 which is always in a horizontal state through a hinge. A plurality of universal wheels 3 are rotatably connected to the lower front end of the bracket 2 to ensure that the bracket 2 is in a horizontal state front and back while reducing the resistance when the bracket 2 rotates. A rotating shaft 6 is inserted in the middle position of the bracket 2, and a servo motor 5 is arranged on one side of the bracket 2. The servo motor 5 and the rotating shaft 6 are transmission-connected, and the rotating shaft 6 and the bracket 2 are intermittently transmission-connected. A connecting rod 11 assembly is axially transmission-connected above the servo motor 5, and the connecting rod 11 assembly changes the inclination angle of the solar panel 1.

[0024] The connecting rod 11 assembly includes a threaded sleeve 10 and a connecting rod 11. One end of the connecting rod 11 is rotatably connected to the back of the solar panel 1, and the other end is rotatably connected to the threaded sleeve 10. The output end of the servo motor 5 is fixedly connected with a threaded rod 9, and the threaded rod 9 and the threaded sleeve 10 are threadedly connected. When the servo motor 5 rotates, the transmission threaded sleeve 10 slides along its axial direction, thereby changing the displacement of the end of the connecting rod 11. Since the length of the connecting rod 11 is fixed, the other end will push and pull the solar panel 1 to maintain the stability of the structure, thereby changing the inclination angle of the solar panel 1. In the morning, the angle between the solar panel 1 and the ground is large. When it enters noon from morning, the angle between the solar panel 1 and the ground gradually decreases. When it enters evening from noon, the angle between the solar panel 1 and the ground gradually increases. By analyzing the trend of the sun in the corresponding time zone and formulating a suitable control program, the servo motor 5 and the electric telescopic rod 12 are controlled by an external control program, so as to achieve the effect of adjusting both, thereby ensuring that the angle between the solar panel 1 and the sun is appropriate.

[0025] The output shaft of the servo motor 5 is also sleeved with a driving wheel 8, and the top end of the rotating shaft 6 is sleeved with a driven wheel 7. The driving wheel 8 and the driven wheel 7 are meshed and connected with each other. The diameters of the driving wheel 8 and the driven wheel 7 are adjusted according to actual needs. The diameter of the driving wheel 8 should be smaller than that of the driven wheel 7, so as to adapt to the situation where the threaded rod 9 needs to rotate a large number of circles when the transmission threaded sleeve 10 rotates, and at the same time, the adjustment accuracy can be effectively increased.

[0026] A support platform 4 is arranged below the rotating shaft 6, and the rotating shaft 6 and the support platform 4 are rotatably connected. The servo motor 5 is fixedly connected to the top of the support platform 4 by bolts. A plurality of through grooves 61 are provided in a circular array at the bottom end of the rotating shaft 6, and a movable block 14 is slidably embedded in the inner side of each through groove 61. The movable block 14 is arranged at one end of the inner side of the rotating shaft 6 and is provided with an outward chamfer. A push block 13 cooperating with the movable block 14 is also arranged on the inner side of the rotating shaft 6, and the top end of the push block 13 is in a truncated cone structure. An electric telescopic rod 12 rotatably connected to the push block 13 is fixedly connected by bolts below the supporting platform 4. The angle of the truncated cone structure is the same as the chamfer of the movable block 14. The electric telescopic rod 12 When the push block 13 moves upward, its top outer wall and the bottom end of the movable block 14 collide with each other, so that the movable block 14 is displaced outward and conflicts with the inner wall of the bracket 2, so that when the servo motor 5 rotates, the power of the driving wheel 8 can be transmitted to the bracket 2 through the driven wheel 7 and the rotating shaft 6, so that the bracket 2 rotates radially around the rotating shaft 6, thereby changing the horizontal orientation of the solar panel 1. The significance of the movable block 14 is that when there is no need for horizontal adjustment, the rotating shaft 6 can rotate independently relative to the bracket 2, and does not operate synchronously with it, and only operates when it is needed, thereby separating it from the adjustment of the vertical inclination angle of the solar panel 1, and improving the scope of application of the device.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
