[0040] The light detection device can monitor the intensity of sunlight so that the photovoltaic panel obtains maximum light. Since the light detection device in the related art is directly exposed to the external environment, it is vulnerable to the influence of dust, rainwater and other external factors. For example, dust will accumulate on the surface of the detection device, blocking light and resulting in a low measurement value; rainwater may penetrate into the device interior, causing a short circuit or damaging electronic components; temperature changes will also cause an offset in the characteristics of the sensor, further reducing the measurement accuracy. In addition, long-term exposure to sunlight and rain may also cause the aging of the device housing material, reducing its overall structural stability.

[0041] Based on this, the present application provides a light detection device to reduce the influence of external environmental factors and improve the accuracy of light detection data.

[0042] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] Please refer to Figures 1 to 4, the light detection device provided by the embodiment of the present application includes a base 100, a light detection component 200, a box body 300, and a first driving member 310.

[0044] A support column 110 is provided on the base 100, and the light detection component 200 is fixedly arranged at the top of the support column 110, and the light detection component 200 is used to detect light information. The box body 300 surrounds the outer periphery of the light detection component 200. A through hole is provided at the bottom of the box body 300, the support column 110 is arranged in the through hole, an opening is provided at the top of the box body 300, and a movable box cover 301 is provided at the opening.

[0045] The first driving member 310 is arranged on the base 100, the output part of the first driving member 310 is connected to the box body 300, and the first driving member 310 can drive the box body 300 to move along the length direction of the support column 110, so that the light detection component 200 can be switched between a display state and a hidden state.

[0046] The base 100 serves as the foundation of the device and plays a role in supporting and fixing other components. The light detection component 200 is arranged at the top of the support column 110 on the base 100, so that the light detection component 200 is suspended, reducing the intrusion of mosquitoes, accumulated water or dust. The box body 300 plays a protective role for the light detection component 200. A through hole is provided at the bottom of the box body 300, and the support column 110 passes through the through hole to ensure that the box body 300 can move up and down along the support column 110; an opening is provided at the top of the box body 300, and a movable box cover 301 is provided at the opening. When the box cover 301 is closed, it can effectively prevent external factors such as dust and rain from entering the box body 300.

[0047] It should be noted that the display state of the light detection component 200 is the state in which the light detection component 200 is exposed. In the display state, the light detection component 200 performs light detection; the hidden state of the light detection component 200 is the state in which the light detection component 200 is hidden in the box body 300. In the hidden state, the box body 300 effectively reduces the influence of external environmental factors on the light detection component 200.

[0048] The first driving member 310 is arranged on the base 100, and its output part is fixedly connected to the box body 300. Exemplarily, the first driving member 310 can be a motor, a hydraulic cylinder or a pneumatic cylinder, etc., and can drive the box body 300 to move along the length direction of the support column 110, so as to make the light detection component 200 appear or be hidden.

[0049] When light detection is required, the lid 301 is opened before the box body 300 moves. After that, the first driving member 310 drives the box body 300 to move downward, and the light detection assembly 200 is exposed and starts to work. When the detection is completed or in case of bad weather conditions, the first driving member 310 drives the box body 300 to move upward. The box body 300 moves to a predetermined position, and then the lid 301 is closed to hide the light detection assembly 200, effectively reducing the entry of external factors such as dust and rain into the light detection assembly 200.

[0050] Therefore, in the embodiment of the present application, the light detection assembly 200 is protected by the movable box body 300, which can effectively avoid the influence of external environmental factors on the performance of the light detection assembly 200, improve the accuracy of the detection data of the light detection assembly 200, thereby improving the stability and reliability of the light detection device, and further being beneficial to improving the photoelectric conversion efficiency of the photovoltaic panel.

[0051] In an optional embodiment, the light detection assembly 200 includes a frame body 210, a light sensor 211, a light tracking sensor 212, a receiving box 215 and a controller. Among them, the frame body 210 is arranged on the support column 110, the light sensor 211 is arranged on the top of the frame body 210 for detecting the light intensity; the light tracking sensor 212 is arranged on the top of the frame body 210 for tracking the position of the light source, the receiving box 215 is arranged on the frame body 210, the controller is arranged in the receiving box 215, and the light sensor 211 and the light tracking sensor 212 are both electrically connected to the controller.

[0052] The frame body 210 serves to fix and support other components. The light sensor 211 and the light tracking sensor 212 are arranged on the top of the frame body 210 to detect light information, and the light information includes the light intensity and the light source direction. The receiving box 215 is arranged on the frame body 210 for accommodating the controller and other electronic components to protect them from the external environment. The controller can be used to process the data from the light sensor 211 and the light tracking sensor 212.

[0053] Exemplarily, the light sensor 211 can adopt a photoresistor, a photodiode, etc. to obtain data of the light intensity. The light tracking sensor 212 can be implemented by a photodiode array or other suitable sensors to determine the direction of the light source. The controller can be a microprocessor, a microcontroller or an integrated circuit, etc.

[0054] In an optional embodiment, the light detection assembly 200 further includes a first fixing plate 201, a second driving member 220 and a second fixing plate 202.

[0055] The first fixed plate 201 is fixedly arranged at the top end of the support column 110; the second driving member 220 is fixedly arranged on the first fixed plate 201; the second fixed plate 202 is fixedly connected to the output shaft of the second driving member 220, and the frame body 210 is arranged on the second fixed plate 202. Wherein, the output shaft of the second driving member 220 is arranged vertically to enable the second fixed plate 202 to rotate horizontally.

[0056] The first fixed plate 201 is arranged at the top end of the support column 110 and is used for supporting and installing the second driving member 220. The second fixed plate 202 is fixedly connected to the output shaft of the second driving member 220, so that the first fixed plate 201 rotates following the output shaft of the second driving member 220. The frame body 210 is arranged on the second fixed plate 202, that is to say, the frame body 210 can rotate following the second fixed plate 202. When the output shaft of the second driving member 220 rotates, it drives the second fixed plate 202 and the frame body 210 to rotate horizontally together, thereby adjusting the angle of the light detection assembly 200 so that the light detection assembly 200 faces the direction with better light. Exemplarily, the second driving member 220 is a servo motor or a stepper motor to facilitate the angle adjustment of the light detection assembly 200.

[0057] Further, in an optional embodiment, please refer to Figure 3 and Figure 4 , a third driving member 230 is arranged between the second fixed plate 202 and the frame body 210. The third driving member 230 is arranged on the second fixed plate 202. Wherein, the output shaft of the third driving member 230 is arranged horizontally, and the output shaft of the third driving member 230 is fixedly connected to the frame body 210.

[0058] The third driving member 230 is arranged on the second fixed plate 202, its output shaft is arranged horizontally, and the output shaft of the third driving member 230 is fixedly connected to the frame body 210. Thus, the third driving member 230 can adjust the pitch angle of the frame body 210 to achieve a more precise angle adjustment for the light detection assembly 200. Exemplarily, the third driving member 230 is a servo motor or a stepper motor.

[0059] In the embodiment of the present application, the overall azimuth angle of the light detection assembly 200 can be adjusted by the second driving member 220, and the pitch angle of the light detection assembly 200 can be adjusted by the third driving member 230. Thus, through the combined action of the second driving member 220 and the third driving member 230, the light detection assembly 200 in this embodiment can adapt to the change of the sun's position, which is beneficial to improving the accuracy of light detection, thereby providing data support for maximizing the light efficiency of the photovoltaic panel.

[0060] In an optional embodiment, the light detection assembly 200 further includes a time relay. The time relay is arranged on the frame body 210, and the time relay, the second driving member 220 and the third driving member 230 are all electrically connected to the controller.

[0061] The time relay can be arranged in the accommodation box 215 of the frame 210 to reduce the erosion of mosquitoes, rain, dew or dust. The time relay is electrically connected to the controller, and the time relay can start or stop the actions of the second driving member 220 and the third driving member 230 at a preset time point.

[0062] In the actual practical process, the controller receives the data of the light chasing sensor 212 and the data of the light sensor 211, and controls the actions of the second driving member 220 and the third driving member 230. The output shaft of the second driving member 220 is arranged vertically, and drives the second fixing plate 202 and the frame 210 thereon to rotate horizontally by rotating the output shaft, so as to adjust the pitch angle of the light detection assembly 200; the output shaft of the third driving member 230 is arranged horizontally, and drives the frame 210 to rotate on the horizontal plane by rotating the output shaft, so as to adjust the azimuth angle of the light detection assembly 200. Under the combined action, the light detection assembly 200 faces the best light direction. During this process, the time relay can control the opening and closing of the second driving member 220 and the third driving member 230 according to the preset time interval.

[0063] In an alternative embodiment, please refer to Figure 4 , the frame 210 includes a first connecting arm 213 and a second connecting arm 214 which are oppositely arranged. The output shaft of the third driving member 230 includes a first shaft 231 and a second shaft 232 which are oppositely arranged. The first connecting arm 213 is fixedly connected to the first shaft 231, and the second connecting arm 214 is fixedly connected to the second shaft 232.

[0064] The frame 210 includes a first connecting arm 213 and a second connecting arm 214 which are oppositely arranged, so that the weight of the frame 210 can be dispersed on the first connecting arm 213 and the second connecting arm 214, so that the output shaft of the third driving member 230 can distribute the load more evenly, so that the third driving member 230 can adjust the angle of the light detection assembly 200 more stably.

[0065] When the third driving member 230 acts, the first shaft 231 and the second shaft 232 rotate simultaneously, driving the first connecting arm 213 and the second connecting arm 214 to rotate synchronously, so as to ensure the stable rotation of the whole frame 210.

[0066] Therefore, in the embodiment of the present application, through the first connecting arm 213 and the second connecting arm 214, the light detection device can adjust the angle of the light detection assembly 200 more stably, which is beneficial to improving the detection accuracy and reliability.

[0067] In an alternative embodiment, the box body 300 is provided with a chute at the box opening, and the box cover 301 is slidably connected to the chute.

[0068] The lid 301 is slidably connected to the chute, making the opening and closing of the lid 301 simpler and faster, and facilitating maintenance and operation. Compared with the hinge connection method, the sliding connection makes the lid 301 more stable during movement and will not shake or fall off due to factors such as wind, improving the overall structural stability of the box body 300. Moreover, the chute forms a good seal between the lid 301 and the box body 300, effectively preventing external factors such as dust and rain from entering the box body 300 and protecting the internal light detection component 200.

[0069] It can be understood that the opening and closing of the lid 301 can be realized manually or automatically. Hereinafter, the automatic control of the lid 301 will be taken as an example for illustration.

[0070] In an alternative embodiment, the light detection device further includes a fourth driving member 320. The fourth driving member 320 is provided on the box wall of the box body 300. The output part of the fourth driving member 320 is fixedly connected to the lid 301, and the fourth driving member 320 can drive the lid 301 to slide so as to switch the box opening between the open state and the closed state.

[0071] In the embodiment of the present application, through the fourth driving member 320, the opening and closing process of the lid 301 can be automated without manual operation, improving the convenience and efficiency of the operation. Since the output part of the fourth driving member 320 is fixedly connected to the lid 301, by driving the lid 301 through the fourth driving member 320, it can be ensured that the lid 301 is more stable during the opening and closing process, reducing the risk of the lid 301 shaking or falling off due to factors such as wind, and improving the overall structural stability of the box body 300.

[0072] Exemplarily, the fourth driving member 320 is a piston cylinder, a hydraulic cylinder or a pneumatic cylinder, so that the lid 301 can realize the sliding opening and closing action. It can be understood that the driving direction of the fourth driving member 320 for the output part is the sliding direction of the lid 301 in the chute.

[0073] In an alternative embodiment, there are at least two support columns 110, and the at least two support columns 110 are spaced apart. The at least two support columns 110 can disperse the load, reduce the pressure borne by a single support column 110, make the whole device more stable, and is beneficial to improving the stability of the whole light detection device. In addition, the spaced support columns 110 can increase the wind resistance of the device. The multiple support columns 110 can better disperse the wind force and reduce the risk of the device shaking or tipping over due to strong wind.

[0074] In an alternative embodiment, the base 100 is provided with positioning holes for positioning and installing the base 100.

[0075] The main function of the positioning holes is to provide accurate positioning points when installing the base 100, ensuring that the base 100 can be firmly fixed in the predetermined position. Through the positioning holes, the operator only needs to pass bolts or other fixing parts through the positioning holes and then fasten them to the ground or other supporting structures to complete the installation, which simplifies the installation process and improves the installation efficiency. Moreover, the positioning holes enable the base 100 to be stably installed on the ground or other supporting structures, reducing the phenomena of shaking or displacement caused by improper installation.

[0076] Exemplarily, before preparing to install the base 100, it is first necessary to drill holes in the ground or other supporting structures to place the fixing bolts; then, place the base 100 in the predetermined position, ensuring that the positioning holes are aligned with the pre-drilled holes on the ground; finally, pass the bolts through the positioning holes and then fasten them with nuts, so that the base 100 is firmly fixed on the ground, thus completing the fixed installation of the base 100.

[0077] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the utility model disclosed herein.
