[0034] Example 1

[0035] like Figure 1-Figure 6 As shown,

[0036] A photovoltaic panel assembly with adjustable angle includes a base plate 1, a rotatable and adjustable mounting platform 2 is arranged on the top of the base plate 1, a first moving photovoltaic assembly 3, a second moving photovoltaic assembly 4 and a third moving photovoltaic assembly 5 are installed on the top of the mounting platform 2 in sequence, the height of the third moving photovoltaic assembly 5 is higher than the height of the second moving photovoltaic assembly 4, and the height of the second moving photovoltaic assembly 4 is higher than the height of the first moving photovoltaic assembly 3.

[0037] like Figure 3 As shown, the first moving photovoltaic assembly 3, the second moving photovoltaic assembly 4 and the third moving photovoltaic assembly 5 all include a left support frame 11 and a right support frame 12, and the left support frame 11 and the right support frame 12 are arranged in parallel. The left support frame 11 and the right support frame 12 are both fixedly mounted on the top of the mounting platform 2, and an angle-adjustable photovoltaic panel body 13 is arranged inside the left support frame 11, inside the right support frame 12 and between the left support frame 11 and the right support frame 12.

[0038] The bottom end of one side of the left support frame 11 and the right support frame 12 is fixedly installed with a convex plate 16, and the side of the left support frame 11 and the right support frame 12 close to each other is provided with a lifting screw rod 17, and the top and bottom of the lifting screw rod 17 are respectively rotatably connected with the top of the left support frame 11 and the right support frame 12 and the convex plate 16. The ends of the left support frame 11 and the right support frame 12 are slidably provided with a lifting plate 18, and the top of the lifting plate 18 is symmetrically provided with vertical threaded holes, and two lifting screw rods 17 are respectively threadedly connected in the two threaded holes. The tops of the two lifting screw rods 17 pass through the left support frame 11 and the right support frame 12 respectively and are fixedly connected with a driving pulley 22 and a driven pulley 21, and the driving pulley 22 is connected to the driven pulley 21 through a belt. A servo motor 23 is fixedly installed on the top of the right support frame 12, and the output shaft end of the servo motor 23 is fixedly connected with the central axis of the driving pulley 22.

[0039] The present invention controls the servo motor 23 to rotate the driving pulley 22, and the two lifting screws 17 are rotated through the transmission connection between the driving pulley 22 and the driven pulley 21. The two lifting screws 17 have the same spiral rotation direction and the same rotation direction.

[0040] A lifting groove 20 is provided in the left support frame 11 and the right support frame 12, and a support plate 19 is slidably connected in the lifting groove 20. The bottom end of the photovoltaic panel body 13 is rotatably connected between the two support plates 19 through a rotating shaft, and the end of the support plate 19 away from the photovoltaic panel body 13 passes through the lifting groove 20 and is fixedly connected to the lifting plate 18.

[0041] In this embodiment, the spiral rotation direction of the two lifting screw rods 17 is the same, and the rotation direction of the two lifting screw rods 17 is the same. The lifting plate 18 can be raised or lowered by threaded connection between the two ends of the lifting plate 18 and the two lifting screw rods 17, and the bottom end of the photovoltaic panel body 13 is rotatably connected between the two support plates 19. When the lifting plate 18 is raised or lowered, the bottom end of the photovoltaic panel body 13 can be pulled up and down, thereby adjusting the angle of the photovoltaic panel body 13.

[0042] like Figure 3 and Figure 4 As shown, the top of the left support frame 11 and the top of the right support frame 12 are both provided with a horizontal slide groove 14, and the middle of the corresponding two side walls of the photovoltaic panel body 13 are provided with a positioning rod 15, and the positioning rod 15 is slidably connected inside the slide groove 14. When the bottom end of the photovoltaic panel body 13 is raised or lowered, the positioning rod 15 of the side wall of the photovoltaic panel body 13 is slidably set in the slide groove 14, so that the angle adjustment of the photovoltaic panel body 13 is more stable.

[0043] like Figure 5 and Figure 6 As shown, the mounting platform 2 and the base plate 1 are both circular plate-shaped structures as a whole. The bottom end of the mounting platform 2 is rotatably connected to the top of the base plate 1 through a bearing. The outer side of the mounting platform 2 is fixedly connected to an outer gear ring 6. The top of the base plate 1 is located outside the mounting platform 2 and is fixedly installed with a mounting frame 7, and a mounting box 8 is fixedly connected inside the mounting frame 7. A drive motor 10 is fixedly installed inside the mounting box 8, and the output shaft end of the drive motor 10 passes through the mounting box 8 and is fixedly connected to a drive gear 9, which is meshed with the outer gear ring 6.

[0044] The driving motor 10 is driven to rotate the driving gear 9, and the mounting platform 2 is rotated by meshing the driving gear 9 and the outer gear ring 6, and the mounting platform 2 is controlled to rotate so that the photovoltaic panel body 13 can face the sunlight to the maximum extent. For example, when it reaches noon, the driving motor 10 is driven to rotate the driving gear 9, and the mounting platform 2 is rotated by meshing the driving gear 9 and the outer gear ring 6, and the mounting platform 2 is controlled to rotate 180 degrees, so that the photovoltaic panel body 13 can conveniently receive sunlight in the second half of the day.

[0045] like Figure 5 As shown, the lengths of the lifting screws 17 in the first motion photovoltaic assembly 3, the second motion photovoltaic assembly 4 and the third motion photovoltaic assembly 5 are equal. By setting the lengths of the lifting screws 17 in the first motion photovoltaic assembly 3, the second motion photovoltaic assembly 4 and the third motion photovoltaic assembly 5 to be equal, the angle adjustment of the photovoltaic panels 13 in the first motion photovoltaic assembly 3, the second motion photovoltaic assembly 4 and the third motion photovoltaic assembly 5 can be synchronized, thereby achieving the purpose of unified adjustment.

[0046] like Figure 5As shown, the heights of the left support frame 11 and the right support frame 12 in the first moving photovoltaic assembly 3 are equal, the heights of the left support frame 11 and the right support frame 12 in the second moving photovoltaic assembly 4, and the heights of the left support frame 11 and the right support frame 12 in the third moving photovoltaic assembly 5 are equal, the height of the photovoltaic panel 13 in the first moving photovoltaic assembly 3 is lower than the height of the photovoltaic panel 13 in the second moving photovoltaic assembly 4, and the height of the photovoltaic panel 13 in the second moving photovoltaic assembly 4 is lower than the height of the photovoltaic panel 13 in the third moving photovoltaic assembly 5.

[0047] The height of the photovoltaic panel 13 in the first moving photovoltaic component 3 is lower than the height of the photovoltaic panel 13 in the second moving photovoltaic component 4, and the height of the photovoltaic panel 13 in the second moving photovoltaic component 4 is lower than the height of the photovoltaic panel 13 in the third moving photovoltaic component 5, so that the photovoltaic panels 13 in the first moving photovoltaic component 3, the second moving photovoltaic component 4 and the third moving photovoltaic component 5 are arranged in a stepped manner without affecting the lighting of each.

[0048] like Figure 3 As shown, the left support frame 11, the right support frame 12, the positioning rod 15, the convex plate 16 and the lifting plate 18 are all made of aluminum alloy or carbon fiber material. Aluminum alloy or carbon fiber material has the characteristics of high strength and light weight, and is suitable for the support structure to ensure the stability and durability of the support.

[0049] The control device of the above-mentioned adjustable angle photovoltaic panel assembly is applied to any of the above-mentioned adjustable angle photovoltaic panel assemblies, and comprises a light sensor module, a time synchronization module, a controller module, a power module, a wireless communication module and a drive module;

[0050] The light sensor module is used to monitor light intensity and obtain light information from different directions in real time;

[0051] The time synchronization module is used to synchronize time information;

[0052] The controller module is used to receive data from the light sensor and calculate the optimal angle and direction of the photovoltaic panel according to the light intensity;

[0053] The power module is used to provide power to the drive component and the controller module;

[0054] The wireless communication module is used to communicate with external devices;

[0055] The driving module is used to adjust the angle of the photovoltaic panel according to the instructions issued by the controller;

[0056] The optical sensor module is electrically connected to the controller module, the controller module is electrically connected to the power module, and the power module is electrically connected to the driving module.

[0057] When the present invention is used, according to the angle of the photovoltaic panel body 13 that needs to be adjusted, the servo motors 23 in the first moving photovoltaic assembly 3, the second moving photovoltaic assembly 4, and the third moving photovoltaic assembly 5 are controlled to work, so that the lifting screw 17 rotates, and the threaded connection between the lifting plate 18 and the lifting screw 17 drives the support plate 19 to be lifted and lowered at the same time. When the support plate 19 is raised, the bottom end of the first moving photovoltaic assembly 3 is pulled up, and the positioning rod 15 on the side wall of the photovoltaic panel body 13 is slidably set inside the slide groove 14, so that the inclination of the photovoltaic panel body 13 becomes smaller until it is close to a horizontal state. When the support plate 19 is lowered, the bottom end of the photovoltaic panel body 13 is pulled down, and the positioning rod 15 on the side wall of the photovoltaic panel body 13 slides to the right to a certain extent, so that the inclination of the photovoltaic panel body 13 is larger, thereby realizing flexible adjustment of the first moving photovoltaic assembly 3. At the same time, the orientation of the photovoltaic panel 13 can be adjusted according to different time periods of the day. For example, when it reaches noon, the drive motor 10 works to rotate the drive gear 9, and the mounting platform 2 is rotated through the meshing connection between the drive gear 9 and the outer gear ring 6. The mounting platform 2 is controlled to rotate 180 degrees, so that the photovoltaic panel 13 can conveniently receive sunlight in the second half of the day.

[0058] The height of the third motion photovoltaic assembly of the present invention is higher than that of the second motion photovoltaic assembly, and the height of the second motion photovoltaic assembly is higher than that of the first motion photovoltaic assembly, so that the first motion photovoltaic assembly, the second motion photovoltaic assembly and the third motion photovoltaic assembly are stepped and can better receive sunlight.

[0059] The servo motors installed in the first moving photovoltaic assembly, the second moving photovoltaic assembly and the third moving photovoltaic assembly of the present invention can simultaneously control the angle adjustment of multiple photovoltaic panels in the assembly, saving power resources and installation costs. The overall structure of the assembly is compact and has high adjustment flexibility.

[0060] The present invention can adjust the orientation of the photovoltaic panels in the first moving photovoltaic assembly, the second moving photovoltaic assembly and the third moving photovoltaic assembly by arranging the mounting platform rotatably on the bottom plate, so as to facilitate receiving sunlight throughout the day.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
