Specific implementation manners

[0017] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0018] In this embodiment, as Figure 1 and Figure 2 shown, a photovoltaic power generation system includes a light tracking detection module 1, an environment detection module 2, a control module 3, an adjustment module 4 and a drive protection module 5. The photovoltaic panel 6 includes a photovoltaic power generation panel 61 and a fixed frame 62.

[0019] Referring to Figure 1 and Figure 2 , the light tracking detection module 1 includes a measuring rod 11 and a photosensitive sensor 12. The measuring rod 11 is fixedly connected to the fixed frame 62, and a photosensitive sensor 12 is installed around the connection end of the measuring rod 11 and the fixed frame 62. The photosensitive sensor 12 is used to detect the shadow position information of the measuring rod 11 and output a light tracking detection signal to the control module 3.

[0020] During use, due to the existence of the incident angle of sunlight, when sunlight shines on the measuring rod 11, the measuring rod 11 generates a shadow, and the shadow of the measuring rod 11 is projected onto the surrounding photosensitive sensor 12. The photosensitive sensor 12 detects the existence of the shadow and outputs a light-chasing detection signal to the control module 3. The control module 3 receives the light-chasing detection signal and analyzes and determines the position of the shadow, and outputs an adjustment control signal according to the position of the shadow to adjust the photovoltaic panel 6. Since the measuring rod 11 is fixedly connected to the photovoltaic panel 6, when the angle of the photovoltaic panel 6 is adjusted, the measuring rod 11 is also adjusted with the adjustment of the photovoltaic panel 6, so real-time detection and real-time adjustment are realized. When the photosensitive sensor 12 cannot detect the existence of the shadow of the measuring rod 11, that is, the photovoltaic panel 6 is facing the sun, thereby ensuring the light conversion efficiency of the photovoltaic panel 6.

[0021] refer to Figure 1 and Figure 3 The adjustment module 4 includes a plurality of adjustment cylinders 41 and a connecting hub 42. One end of the adjustment cylinder 41 is fixedly connected to the base 7, and the other end of the adjustment cylinder 41 is rotatably connected to the connecting hub 42. The connecting hub 42 is fixedly connected to the fixed frame 62. The plurality of adjustment cylinders 41 are evenly distributed on one side of the fixed frame 62. The number and position of the connecting hub 42 correspond to the number and position of the adjustment cylinders 41.

[0022] During use, the adjusting cylinder 41 receives the adjusting control signal and starts. Through the interaction of multiple adjusting cylinders 41, the photovoltaic panel 6 can be adjusted at any angle, so that the photovoltaic panel 6 moves and lifts relative to the shadow position until the photosensitive sensor 12 cannot detect the shadow of the measuring rod 11, that is, the photovoltaic panel 6 is facing the sunlight, realizing real-time detection of the incident angle of sunlight and real-time adjustment of the photovoltaic panel 6, and improving the light conversion efficiency of the photovoltaic panel 6. During the adjustment process, the photovoltaic panel 6 is tilted to a certain extent due to the extension or contraction of the adjusting cylinder 41. Through the rotational connection between the adjusting cylinder 41 and the connecting hub 42, the photovoltaic panel 6 can still be connected to the adjusting cylinder 41 when tilted, avoiding the fracture between the adjusting cylinder 41 and the photovoltaic panel 6 due to the tilt, which affects the service life.

[0023] refer to Figure 3 The driving protection module 5 includes a driving motor 51 and a plurality of metal sheets 52. The plurality of metal sheets 52 are nested and connected with each other. The innermost layer of the nested metal sheets 52 is fixedly connected to the fixed frame 62, and the outermost layer of the nested metal sheets 52 is fixedly connected to the driving motor 51. A driving gear is coaxially fixed on the output shaft of the driving motor 51. Tooth grooves are provided on both sides of the fixed frame 62, and the driving gear and the tooth grooves are meshed with each other.

[0024] refer to Figure 1 and Figure 2, the environmental detection module 2 includes a temperature and humidity sensor 21 and a rain sensor 22. Both the temperature and humidity sensor 21 and the rain sensor 22 are installed on the outermost layer of the nested metal sheets 52, and are used to detect the changes in temperature and humidity in the environment and the rainfall situation, and correspondingly output temperature and humidity detection signals and rain detection signals.

[0025] In operation, the temperature and humidity sensor 21 detects the temperature change in the environment and outputs a temperature and humidity detection signal. The control module 3 receives the temperature and humidity detection signal and determines whether condensation will occur. If condensation occurs, the control module 3 outputs a drive signal.

[0026] The rain detection signal detects the rainfall situation in the environment and outputs a rain detection signal. The control module 3 receives the rain detection signal and determines whether there is a rainfall phenomenon. If there is a rainfall phenomenon, the control module 3 outputs a drive signal.

[0027] The drive motor 51 receives the drive signal and starts to rotate to drive the drive gear to rotate. The drive gear meshes with the tooth groove, so that the drive motor 51 moves on the tooth groove, thereby driving the nested metal sheets 52 to unfold to protect the photovoltaic panel 6, reducing the damage to the photovoltaic panel 6 in the harsh environment, and reducing the influence of condensation, water flow and residual water stains on the light conversion efficiency of the photovoltaic panel 6.

[0028] Based on the description of the above photovoltaic power generation system embodiment, the embodiment of the present invention also discloses a photovoltaic power generation device: Reference Figure 2 and Figure 3 , a photovoltaic power generation device, includes: a base 7, an adjustment module 4, a light tracking detection module 1, an environmental detection module 2, a drive protection module 5 and a photovoltaic panel 6. The base 7 is installed on the ground for fixing the position. The base 7 and the photovoltaic panel 6 are rotationally connected by a universal shaft 8, so that the photovoltaic panel 6 can rotate at any angle with the universal shaft 8 as the center. The photovoltaic panel 6 includes a photovoltaic power generation board 61 and a fixed frame 62. The photovoltaic power generation board 61 is installed in the fixed frame 62, so that the fixed frame 62 protects the photovoltaic power generation board 61.

[0029] Reference Figure 2 and Figure 3 , the adjustment module 4 includes a plurality of adjustment cylinders 41 and connection hubs 42. The adjustment cylinders 41 are installed on the base 7. The other end of the adjustment cylinder 41 is rotationally connected to the connection hub 42. The connection hub 42 is fixedly connected to the fixed frame 62. The plurality of adjustment cylinders 41 are evenly distributed on one side of the base 7. The number and position of the connection hubs 42 correspond to the number and position of the adjustment cylinders 41.

[0030] In operation, multiple adjustment cylinders 41 control the activation of adjustment cylinders 41 at different positions according to the adjustment control signal. For example, they control the expansion and contraction of the adjustment cylinders 41 to different degrees and quantities, causing the multiple adjustment cylinders 41 to be arranged in a gradient pattern in sequence. As a result, the fixed frame 62 presents an inclined slope consistent with that of the adjustment cylinders 41. Similarly, when the multiple adjustment cylinders 41 expand or contract at the same horizontal height, since one end of the fixed frame 62 is fixed and the other end is lifted or lowered, the fixed frame 62 also becomes inclined at a certain slope. With the cooperation of the universal shaft 8, the fixed frame 62 can be adjusted at any angle. Through the mutual cooperation of the multiple adjustment cylinders 41 and the universal shaft 8, the photovoltaic panel 6 can adjust its orientation within the same spatial area, avoiding large-area displacement during the orientation adjustment of the photovoltaic panel 6 by rotation, reducing the floor area occupied by the photovoltaic panel 6, and increasing the land utilization rate.

[0031] During the adjustment process, due to the expansion or contraction of the adjustment cylinders 41, the photovoltaic panel 6 generates a certain inclination. Through the rotational connection between the adjustment cylinders 41 and the connection hubs 42, the photovoltaic panel 6 can still maintain connection with the adjustment cylinders 41 when it is inclined, avoiding breakage between the adjustment cylinders 41 and the photovoltaic panel 6 caused by the inclination and affecting the service life.

[0032] Reference Figure 2 , the light-tracking detection module 1 includes a measuring rod 11 and a photosensitive sensor 12. The measuring rod 11 is fixedly connected to the fixed frame 62, and photosensitive sensors 12 are distributed around the connection end of the measuring rod 11 and the fixed frame 62. The photosensitive sensors 12 are used to detect the position of the shadow of the measuring rod 11.

[0033] In operation, due to the incident angle of sunlight, when sunlight shines on the measuring rod 11, the measuring rod 11 generates a shadow, and the shadow of the measuring rod 11 is projected onto the photosensitive sensors 12, enabling the photosensitive sensors 12 to detect the shadow.

[0034] Combined with the adjustment module 4, according to the shadow information, the adjustment cylinders 41 adjust the photovoltaic panel 6. When the photosensitive sensors 12 do not detect the shadow, it indicates that the measuring rod 11 is facing the sun, thus indicating that the photovoltaic panel 6 is facing the sun, and further improving the conversion efficiency of the photovoltaic panel 6.

[0035] Reference Figure 3 , the drive protection module 5 includes a drive motor 51 and multiple metal sheets 52. The multiple metal sheets 52 are nested and connected to each other. The innermost metal sheet 52 of the nested metal sheets 52 is fixedly connected to one end of the fixed frame 62, and the outermost metal sheet 52 of the nested metal sheets 52 is fixedly connected to the drive motor 51. The output shaft of the drive motor 51 is coaxially connected with a drive gear, and tooth grooves are provided on both sides of the fixed frame 62. The drive gear meshes with the tooth grooves.

[0036] In operation, when the drive motor 51 starts, the drive motor 51 rotates to drive the drive gear to rotate. The drive gear meshes with the tooth groove, causing the drive motor 51 to move on the tooth groove, thereby driving the nested metal sheets 52 to expand and contract. This enables the metal sheets 52 to effectively cover the photovoltaic panel 6 and protect the photovoltaic panel 6.

[0037] Reference Figure 2 , the environment detection module 2 includes a temperature and humidity sensor 21 and a rain sensor 22. Both the temperature and humidity sensor 21 and the rain sensor 22 are provided on the outermost nested metal sheet 52. The temperature and humidity sensor 21 is used to detect changes in temperature and humidity in the environment, and the rain sensor 22 is used to detect the rainfall condition in the environment.

[0038] In operation, in combination with the drive protection module 5, when the temperature and humidity sensor 21 detects that the temperature difference and air humidity can reach the dew point, the drive protection module 5 is started, and the drive motor 51 starts to achieve full coverage of the photovoltaic panel 6, reducing the generation of condensation on the photovoltaic panel 6, thereby reducing the water stains on the photovoltaic panel 6 caused by condensation and the reduction of the light conversion efficiency of the photovoltaic panel 6 due to the condensation itself. When the rain sensor 22 detects environmental rainfall, the drive protection module 5 is started, and the drive motor 51 starts to protect the photovoltaic panel 6.

[0039] The embodiment of the present invention also provides a photovoltaic power generation control method.

[0040] Reference Figure 4 , in this embodiment, a photovoltaic power generation control method includes the following steps: S1: Based on the light tracking detection module 1, detect the incident angle of sunlight and the photovoltaic panel 6, and output a light tracking detection signal.

[0041] S2: Based on the environment detection module 2, detect the environmental changes where the photovoltaic panel 6 is located, and output an environment detection signal.

[0042] S3: Based on the control module 3, analyze and process the light tracking detection signal to obtain an adjustment control signal.

[0043] S4: Based on the adjustment control signal, start the adjustment module 4 to perform corresponding angle adjustment on the photovoltaic panel 6.

[0044] S5: According to the environment detection signal, the control module 3 analyzes the environment detection signal and correspondingly outputs a drive signal.

[0045] S6: Based on the drive signal, start the drive protection module 5 to protect the photovoltaic panel 6.

[0046] Compared with the existing photovoltaic power generation control methods, systems, and devices, the present application improves the light conversion efficiency of the photovoltaic panel 6.

[0047] The implementation principle of the embodiments of this application is as follows: When sunlight shines on the photovoltaic power generation device, due to the incident angle of sunlight, the sunlight shines on the measuring rod 11, causing the measuring rod 11 to produce a shadow. The shadow of the measuring rod 11 is projected onto the photosensitive sensor 12. The photosensitive sensor 12 detects the shadow of the measuring rod 11 and outputs a light-tracking detection signal. The control module 3 receives the light-tracking detection signal and processes it to output an adjustment control signal. The adjustment cylinder 41 receives the adjustment control signal and starts the multiple adjustment cylinders 41 at different heights according to the start data of the adjustment control signal. With the mutual cooperation of the adjustment cylinder 41 and the universal shaft 8, the photovoltaic panel 6 can be adjusted in any direction and at any angle. When the photosensitive sensor 12 cannot detect the shadow of the measuring rod 11, it means that the photovoltaic panel 6 is facing the sun directly, thereby improving the light conversion efficiency of the photovoltaic panel 6.

[0048] The temperature and humidity sensor 21 detects the temperature change and humidity value in the environment and outputs a temperature detection signal and a humidity detection signal. The control module 3 receives the temperature detection signal and the humidity detection signal and analyzes and judges whether condensation will occur. If condensation occurs, the control module 3 outputs a driving signal to the driving motor 51. The rain sensor 22 detects the rainfall condition in the environment and outputs a rainfall detection signal. The control module 3 receives the rainfall detection signal and analyzes it. If there is a rainfall condition, the control module 3 outputs a driving signal to the driving motor 51. The driving motor 51 receives the driving signal and starts to drive the driving gear to rotate. The driving gear meshes with the tooth groove, enabling the driving motor 51 to move on the tooth groove, thereby driving the metal sheet 52 to unfold and cover the photovoltaic power generation panel 61, thus protecting the photovoltaic power generation panel 61 and preventing the light conversion efficiency of the photovoltaic panel 6 from being affected by condensation, water flow, and water stains left by condensation or water flow.

[0049] The above are all the preferred embodiments of this application. Without limiting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
