Description

Automatic light-sensing wind and snow removal array photovoltaic support Technical Field

[0001] This application relates to the field of photovoltaic new energy technology, specifically to an automatic light-sensing wind and snow removal array photovoltaic support. Background Technology

[0002] Photovoltaics, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Solar photovoltaic power generation systems are classified into centralized and distributed systems. Photovoltaic support structures are special brackets used to place, install, and fix solar panels in a solar power generation system. They are a key component of the system; photovoltaic support structures are generally fixed to the ground, roof, or other structures. They support the main power generation components of the photovoltaic power station, ensuring that the photovoltaic modules are stably positioned at the optimal angle and location to maximize the reception of solar radiation and improve overall power generation efficiency. In addition, photovoltaic support structures not only improve the efficiency of the photovoltaic system but also protect the photovoltaic modules from external damage, extending the system's lifespan.

[0003] The power generation of photovoltaic (PV) modules is highly dependent on the angle at which sunlight shines upon them, with maximum power generation occurring when the panels are directly facing the sun. However, the angle of sunlight changes constantly throughout the day, and the direction of sunrise and sunset varies significantly across different seasons. Conventional fixed PV mounting systems cannot maximize the reception of solar radiation daily, nor can they achieve maximum power generation for different seasons.

[0004] A patent discloses a photovoltaic panel angle adjustment system. This system uses an intelligent device to control a power module and a transmission module, causing each photovoltaic panel support frame to move along a corresponding arc-shaped guide rail to a preset position. This automatically adjusts the angle of each photovoltaic panel support frame, thereby automatically adjusting the angle of each photovoltaic panel in the photovoltaic array. However, this photovoltaic panel angle adjustment system can only adjust the angle of a single photovoltaic module. Existing photovoltaic panels are often installed using a large-area, dot-matrix pattern, making individual adjustment time-consuming, labor-intensive, difficult to implement, and impractical. A patent discloses a flexible photovoltaic support structure, its array structure, and an angle adjustment method. Although the structure is achieved by hingedly connecting the two ends of the horizontal support arm of the T-shaped transmission rod and the free end of the vertical support arm to the inclined support rod and the drive structure respectively, the vertical support arm is constrained by the inclined support rod when it moves, thereby driving the photovoltaic panel to perform a tilting motion with rotational and translational coupling; however, the angle adjustment range of the photovoltaic support structure is limited by its structure, making it impossible to effectively clean the surface of the photovoltaic panel by adjusting the angle. For example, it cannot remove snow and ice in time, affecting the working efficiency of the solar panel. It also cannot avoid danger in windy weather, which is not conducive to extending the service life of the solar panel. Summary of the Invention

[0005] In view of the technical problems existing in the background art, this application provides an automatic light-sensing wind and snow removal array photovoltaic support. This photovoltaic support realizes the angle adjustment of large-area array photovoltaic panels, and has a large angle adjustment range, a high degree of automation, and a wide range of applications.

[0006] In a first aspect, embodiments of this application provide an automatic light-tracking, sensing-based wind and snow removal array-type photovoltaic support. The photovoltaic support includes a base support, a light-tracking rotation system and a wind resistance sensor mounted on the base support, and a photovoltaic module fixing frame connecting the light-tracking rotation system and the photovoltaic modules. It also includes an energy storage device, an inverter connecting the energy storage device and the photovoltaic modules, and an intelligent controller connecting the light-tracking rotation system, the wind resistance sensor, and the energy storage device. The light-tracking rotation system is equipped with a multi-stage transmission unit connecting a large-area array of photovoltaic modules, an angle adjustment unit connected to the multi-stage transmission unit, and a light-tracking sensor to achieve automatic light tracking, intelligent adjustment of the angle of the large-area array of photovoltaic modules, and sensing-based wind and snow removal functions.

[0007] In the technical solution of this application embodiment, by setting up a multi-stage transmission unit connecting large-area array photovoltaic modules and adopting a stable mechanical drive transmission mechanism, the large-area array photovoltaic panels can be adjusted in angle over a large area and range according to the solar rotation law. By setting up angle adjustment units, tracking sensors, and wind resistance sensors, in conjunction with an intelligent controller and actual weather conditions, the photovoltaic panels can automatically track the sun, intelligently and flexibly adjust the angle, and automatically avoid danger in windy and snowy weather. This photovoltaic support system enables the photovoltaic modules to maximize the reception of solar radiation, improve their overall power generation efficiency, avoid damage to the photovoltaic modules caused by severe weather, and extend the service life of the photovoltaic modules.

[0008] In some embodiments, the base support is provided on both sides of the large-area array photovoltaic module and includes civil engineering support, support column, support truss and diagonal support. The civil engineering support is provided at the bottom of the photovoltaic support. The upper and lower ends of the support column are fixedly connected to the support truss and the civil engineering support, respectively. The diagonal support is inclined on both sides of the support column. The two ends of the diagonal support are fixedly connected to the support column and the support truss, respectively.

[0009] In this embodiment, the photovoltaic support can be adapted to any environment by setting up a basic support structure, such as being fixed to the ground, roof or other structures by civil engineering support.

[0010] In some embodiments, the multi-stage transmission unit includes several parallel multi-stage transmission shafts that pass through the supporting trusses on both sides of the large-area array photovoltaic module. The multi-stage transmission unit also includes truss fixed bearings and drive sprockets located at both ends of the multi-stage transmission shafts, a motor drive connecting any of the multi-stage transmission shafts, and a fixed frame support that fixes the multi-stage transmission shafts to the photovoltaic module mounting frame. The motor drive is connected to the intelligent controller. The truss fixed bearings are located at both ends of the multi-stage transmission shafts and are rotatably connected to the supporting trusses. The drive sprockets are fixed at both ends of the multi-stage transmission shafts and located near the connection between the multi-stage transmission shafts and the supporting trusses. The same drive chain is installed on the drive sprockets on the same side of the multiple multi-stage transmission shafts, achieving synchronous driving of the multiple drive sprockets on the same side.

[0011] In this embodiment, the multi-stage transmission unit of the light-following rotation system provides power to the rotation of the multi-stage transmission shafts at appropriate times by setting a motor drive connected to the intelligent controller. When the multi-stage transmission shafts rotate, they drive the drive sprockets to rotate, which in turn drives more drive sprockets meshing with them to rotate through the drive chain. Therefore, several multi-stage transmission shafts rotate simultaneously under the action of the drive chain and drive sprockets, causing the fixed frame supports fixed on several multi-stage transmission shafts to rotate. At the same time, the photovoltaic module fixing frame set on the fixed frame support and each photovoltaic module in the large-area array are driven by the light-following rotation system, thereby realizing the intelligent adjustment of the angle of the large-area array photovoltaic modules.

[0012] In some embodiments, the angle adjustment unit includes an angle detection block disposed on any of the multi-stage transmission shafts and an angle adjustment brake disposed on the support truss, the angle adjustment brake being connected to the intelligent controller. The light-tracking sensor is disposed on any of the multi-stage transmission shafts and connected to the intelligent controller to accurately sense the direction and intensity of sunlight, enabling flexible adjustment of the photovoltaic support angle.

[0013] In this embodiment, a light-tracking sensor connected to an intelligent controller is installed in the light-tracking rotation system to accurately sense the direction and intensity of sunlight and feed it back to the intelligent controller. The intelligent controller then controls the motor drive of the multi-stage transmission unit to achieve intelligent adjustment of the angle of the large-area array photovoltaic module. In addition, by setting an angle adjustment unit connected to the intelligent controller, after the angle adjustment brake detects that the angle detection block on the multi-stage transmission shaft has reached the target angle, the intelligent controller controls the motor drive to stop working, so that the multi-stage transmission unit controls the photovoltaic module to be fixed at a suitable angle, thereby achieving the maximum solar energy reception efficiency.

[0014] In some embodiments, the wind resistance sensor is located at one end of the support truss and connected to the intelligent controller to detect the wind force and adjust the angle of the photovoltaic module to achieve the purpose of unloading the wind.

[0015] In this embodiment, a wind resistance sensor is set to detect the wind force and feed it back to the intelligent controller. The intelligent controller then controls the motor drive of the multi-stage transmission unit to achieve intelligent adjustment of the angle of the large-area array photovoltaic module, ensuring that the photovoltaic module maintains the optimal force relief angle with the wind direction and protecting the photovoltaic module from damage.

[0016] In some embodiments, the photovoltaic module mounting bracket is fixedly connected to each photovoltaic module arranged in a large-area array, and the multi-stage transmission shaft of the multi-stage transmission unit is connected through the mounting bracket support, so that the large-area array photovoltaic modules can rotate with the multi-stage transmission unit.

[0017] In this embodiment, by setting up a photovoltaic module fixing frame that connects the large-area array of photovoltaic modules with a multi-stage drive shaft, the angle adjustment range between the photovoltaic modules is not affected by each other, and a wide range of angle adjustment can be achieved. For example, in severe snow and ice weather, it can ensure that the photovoltaic modules stand vertically to avoid being covered by snow and ice.

[0018] In some embodiments, the inverter is mounted on the base support, and the input end of the inverter is connected to each photovoltaic module of the large-area array photovoltaic module via cables, and the output end is connected to the energy storage device via cables; the energy storage device is connected to the light-driven rotation system to provide energy to it.

[0019] In this embodiment, by setting up an inverter connected to the photovoltaic module and the energy storage device, the photovoltaic module receives solar energy and converts it into electrical energy, which is then collected by the inverter and transmitted to the energy storage device. The energy storage device then provides the electrical energy to the intelligent controller and the light-following rotation system, realizing the cyclical application of energy. This allows the photovoltaic bracket to achieve its automatic light-following sensing, wind removal, and snow removal functions without consuming much external energy.

[0020] In some embodiments, the motor drive is fixedly connected to the support truss and connected to any of the multi-stage transmission shafts to provide them with the main driving force.

[0035] Photovoltaic (PV) mounting systems are specialized supports used to place, install, and secure solar panels in a solar power generation system. They are a crucial component, not only improving system efficiency but also protecting PV modules from external damage and extending system lifespan. Conventional fixed PV mounting systems cannot maximize daily solar radiation reception and cannot achieve maximum power generation in different seasons. Existing angle-adjustable PV mounting systems can only adjust the angle of individual PV modules. Since PV panels are often installed in a large-area, dot-matrix pattern, individual adjustment is time-consuming, labor-intensive, difficult to implement, and impractical. Furthermore, the angle adjustment range of some PV mounting systems is limited by their structure, making it impossible to effectively clean the PV panel surface using angle adjustment. For example, snow and ice cannot be removed promptly, affecting the working efficiency of the solar panels. They also cannot provide protection during strong winds, hindering the extension of the solar panels' service life.

[0036] To address the technical problems of limited angle adjustment range, inability to maximize solar radiation reception, lack of automatic cleaning, and inability to avoid damage in severe weather, existing photovoltaic (PV) support systems provide an automatic light-tracking, wind-relief, and snow-clearing array-type PV support system. By incorporating a light-tracking rotation system and a stable mechanical drive transmission mechanism, it achieves large-area, wide-range angle adjustment of the PV panels according to the sun's rotation. Furthermore, by integrating angle adjustment units, light-tracking sensors, and wind resistance sensors, along with an intelligent controller that adjusts to actual weather conditions, it enables automatic light tracking, intelligent and flexible angle adjustment, and automatic protection against strong winds and snow. This PV support system achieves large-area array angle adjustment of PV panels with a wide range of adjustment, a high degree of automation, and broad applicability.

[0037] For ease of explanation, the following embodiments use an automatic light-sensing wind and snow removal array photovoltaic support 100 according to an embodiment of this application as an example.

[0038] Please refer to Figures 1 and 2, which are schematic diagrams of the structure of the automatic light-tracking sensing wind-removing and snow-clearing array photovoltaic support 100 and a top view of the light-tracking rotation system provided in the embodiments of this application. The photovoltaic support includes a base support 110, a light-tracking rotation system 120 and a wind resistance sensor 130 mounted on the base support 110, and a photovoltaic module fixing frame 140 connecting the light-tracking rotation system 120 and the photovoltaic module 200; it also includes an energy storage device 150, an inverter 160 connecting the energy storage device 150 and the photovoltaic module 200, and an intelligent controller 170 connecting the light-tracking rotation system 120, the wind resistance sensor 130, and the energy storage device 150; the light-tracking rotation system 120 is provided with a multi-stage transmission unit 121 connecting a large-area array photovoltaic module, an angle adjustment unit 122 connected to the multi-stage transmission unit 121, and a light-tracking sensor 123, so as to realize the functions of automatic light-tracking, intelligent adjustment of the angle of the large-area array photovoltaic module, and sensing wind-removing and snow-clearing.

[0039] By setting up a multi-stage transmission unit 121 connecting a large-area array of photovoltaic modules in the light-following rotation system 120, and adopting a stable mechanical drive transmission mechanism, the large-area array of photovoltaic panels can be adjusted in a large area and over a wide range according to the rotation law of the sun. By setting up an angle adjustment unit 122, a light-following sensor 123, and a wind resistance sensor 130, and cooperating with an intelligent controller 170 to control the photovoltaic panels automatically follow the light and adjust the angle intelligently and flexibly, as well as automatically avoid danger in windy and snowy weather. This photovoltaic support allows the photovoltaic modules 200 to maximize the reception of solar radiation, improve their overall power generation efficiency, avoid damage to the photovoltaic modules 200 caused by severe weather, and extend the service life of the photovoltaic modules 200.

[0040] It should be noted that, in order to show the structure and positional relationship of each component of the automatic light-sensing wind and snow removal array photovoltaic support 100 as much as possible, some shading components have been made transparent and the connection relationship of some components has been omitted, so as to clearly illustrate the structure and position of the internal components.

[0041] Furthermore, in this embodiment of the application, as shown in FIG1, the base support 110 is provided on both sides of the large-area array photovoltaic module, including civil support 111, support column 112, support truss 113 and diagonal support 114. The civil support 111 is provided at the bottom of the photovoltaic support. The upper and lower ends of the support column 112 are fixedly connected to the support truss 113 and the civil support 111, respectively. The diagonal support 114 is inclined on both sides of the support column 112, and the two ends of the diagonal support 114 are fixedly connected to the support column 112 and the support truss 113, respectively.

[0042] In this embodiment, the automatic light-sensing wind and snow removal array photovoltaic support 100 can be adapted to any environment for construction, such as being fixed to the ground, roof or other structures by civil engineering support 111.

[0043] Further, in the embodiments of this application, as shown in Figures 2 and 3, the multi-stage transmission unit 121 includes several parallel multi-stage transmission shafts 1211. The multi-stage transmission shafts 1211 pass through the support trusses 113 on both sides of the large-area array photovoltaic module. The multi-stage transmission unit 121 also includes truss fixed bearings 1212 and drive sprockets 1213 at both ends of the multi-stage transmission shafts 1211, a motor drive 1214 connecting any multi-stage transmission shaft 1211, and a fixed frame support 1215 that fixes the multi-stage transmission shafts 1211 to the photovoltaic module fixing frame 140. The motor drive 1214 is connected to the intelligent controller 170. The truss fixed bearing 1212 is located at both ends of the multi-stage transmission shaft 1211 and is rotatably connected to the support truss 113; the drive sprocket 1213 is fixed at both ends of the multi-stage transmission shaft 1211 and is located near the connection between the multi-stage transmission shaft 1211 and the support truss 113. The same drive chain 1216 is installed on the drive sprocket 1213 located on the same side of several multi-stage transmission shafts 1211, so as to realize the synchronous drive of several drive sprockets 1213 on the same side.

[0044] In this embodiment, the multi-stage transmission unit 121 of the light-following rotation system 120 provides power to the rotation of the multi-stage transmission shaft 1211 at appropriate times by setting a motor drive 1214 connected to the intelligent controller 170. When the multi-stage transmission shaft 1211 rotates, it drives the drive sprocket 1213 to rotate, and then drives more drive sprockets 1213 meshing with it to rotate through the drive chain 1216. Therefore, several multi-stage transmission shafts 1211 rotate simultaneously under the action of the drive chain 1216 and the drive sprockets 1213, so that the fixed frame support 1215 fixed on several multi-stage transmission shafts 1211 rotates. At the same time, the photovoltaic module fixing frame 140 set on the fixed frame support 1215 and each photovoltaic module 200 arranged in a large area array rotate with the drive of the light-following rotation system 120, thereby realizing the intelligent adjustment of the angle of the large area array photovoltaic module.

[0045] Further, in this embodiment of the application, as shown in FIG2, the angle adjustment unit 122 includes an angle detection block 1221 disposed on any multi-stage transmission shaft 1211 and an angle adjustment brake 1222 disposed on the support truss 113. The angle adjustment brake 1222 is connected to the intelligent controller 170. The light tracking sensor 123 is disposed on any multi-stage transmission shaft 1211 and connected to the intelligent controller 170 to accurately sense the direction and intensity of sunlight, thereby realizing flexible adjustment of the photovoltaic support angle.

[0046] In this embodiment, a light-tracking sensor 123 connected to an intelligent controller 170 is installed in the light-tracking rotation system 120 to accurately sense the direction and intensity of sunlight and feed it back to the intelligent controller 170. The intelligent controller 170 then controls the motor drive 1214 of the multi-stage transmission unit 121 to achieve intelligent adjustment of the angle of the large-area array photovoltaic module. In addition, by setting an angle adjustment unit 122 connected to the intelligent controller 170, after the angle adjustment brake 1222 detects that the angle detection block 1221 on the multi-stage transmission shaft 1211 has reached the target angle, the intelligent controller 170 controls the motor drive 1214 to stop working, so that the multi-stage transmission unit 121 controls the photovoltaic module 200 to be fixed at a suitable angle, thereby achieving the maximum solar energy reception efficiency.

[0047] Furthermore, in this embodiment, the wind resistance sensor 130 is located at one end of the support truss 113 and connected to the intelligent controller 170 to detect the wind force and adjust the angle of the photovoltaic module 200 to achieve the purpose of unloading the wind.

[0048] In this embodiment, the wind resistance sensor 130 is set to detect the wind force and feed it back to the intelligent controller 170. The intelligent controller 170 then controls the motor drive 1214 of the multi-stage transmission unit 121 to realize the intelligent adjustment of the angle of the large-area array photovoltaic module, ensuring that the photovoltaic module 200 maintains the best force relief angle with the wind direction and protecting the photovoltaic module 200 from damage.

[0049] Furthermore, in this embodiment, the photovoltaic module mounting bracket 140 is fixedly connected to each photovoltaic module 200 arranged in a large-area array, and is connected to the multi-stage transmission shaft 1211 of the multi-stage transmission unit 121 through the mounting bracket support 1215, so that the large-area array photovoltaic modules can rotate with the multi-stage transmission unit 121.

[0050] In this embodiment, by setting up a photovoltaic module fixing frame 140 that connects the large-area array of photovoltaic modules 200 with the multi-stage drive shaft 1211, the angle adjustment range between the photovoltaic modules 200 is not affected by each other, and a wide range of angle adjustment can be achieved. For example, in severe snow and ice weather, the photovoltaic modules 200 can be kept vertical to avoid being covered by snow and ice.

[0051] Furthermore, in this embodiment, the inverter 160 is mounted on the base support 110. The input end of the inverter 160 is connected to each photovoltaic module 200 of the large-area array photovoltaic module via cables, and the output end is connected to the energy storage device 150 via cables. The energy storage device 150 is connected to the light-driven rotation system 120 to provide it with energy.

[0052] In this embodiment, by setting up an inverter 160 connected to the photovoltaic module 200 and the energy storage device 150, the photovoltaic module 200 receives solar energy and converts it into electrical energy, which is then collected by the inverter 160 and transmitted to the energy storage device 150. The energy storage device 150 then provides the electrical energy to the intelligent controller 170 and the light-following rotation system 120, realizing the cyclical application of energy. This allows the photovoltaic support to achieve its automatic light-following sensing, wind removal, and snow removal functions without consuming much external energy.

[0053] Furthermore, in this embodiment, the motor drive 1214 is fixedly connected to the support truss 113 and connected to any multi-stage transmission shaft 1211 to provide the main driving force for its rotation.

[0054] Please refer to Figures 1 to 3 together. According to one or more embodiments of this application, the working principle of this application is as follows:

[0055] When the photovoltaic power station is working normally, the photovoltaic modules 200 receive solar energy and convert it into electrical energy, which is then collected by the inverter 160 and sent to the energy storage device 150. As the angle of the sun changes with sunrise and sunset, in order for the photovoltaic modules 200 to utilize solar energy with the highest efficiency, the intelligent controller 170 accurately senses the direction and intensity of sunlight based on the light-tracking sensor 123, and controls the energy storage device 150 to supply power to the motor drive 1214. The rotation of the motor drive 1214 drives the multi-stage transmission shaft 1211 to rotate, which in turn drives the drive sprocket 1213 to rotate. The active drive sprocket 1213 drives more drive sprockets 1213 to rotate simultaneously via the drive chain 1216. This allows several multi-stage transmission shafts 1211 to rotate simultaneously under the action of the drive chain 1216 and the drive sprockets 1213. The multi-stage transmission shafts 1211 then drive the fixed frame support 1215 to rotate. At the same time, the photovoltaic modules 200 arranged in a large-area array and the photovoltaic module fixed frame 140 rotate with the drive of the light-tracking rotation system 120. When the angle detection block 1221, fixed on the multi-stage drive shaft 1211, rotates until the angle detected by the angle adjustment brake 1222 reaches the target angle of the intelligent controller 170, the intelligent controller 170 controls the energy storage device 150 to stop supplying power to the motor drive 1214, and the light-by-light rotation system 120 stops working, ensuring that the photovoltaic module 200 receives solar energy at a suitable angle. In case of strong winds or snow, based on the signal transmitted by the wind resistance sensor 130, the intelligent controller 170 controls the light-by-light rotation system 120 to work to ensure that the photovoltaic module 200 maintains the optimal stress relief angle with the wind direction, protecting the photovoltaic module 200 from damage, or ensuring that the large-area array photovoltaic module stands vertically to avoid being covered by ice and snow in severe snow and ice weather.

[0056] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
