Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and more specifically, to a concentrating control device for photovoltaic modules. Background Technology

[0002] A concentrating control device for photovoltaic modules is a device that uses optical and mechanical means to focus sunlight onto a small area of ​​photovoltaic modules, thereby increasing the light intensity per unit area. This design can significantly reduce the area of ​​photovoltaic modules used, reduce system costs, and improve power generation efficiency. The concentrating control device uses optical focusing, dynamic tracking, and thermal management technologies to efficiently convert scattered sunlight into electrical energy. It is suitable for scenarios such as high-concentration photovoltaics, building-integrated photovoltaics, and power supply in remote areas.

[0003] The existing application number: CN202010144733.8 discloses a rooftop concentrating photovoltaic power generation device, which solves the problem that "when a general photovoltaic power generation device is used on a sloping roof, the light is easily limited by time, the light is poor for a long time of day, the photovoltaic power generation efficiency is low, and the commonly used adjustment device has certain safety problems."

[0004] The inventors have discovered the following problems in the existing technology: In the existing technology, the method of concentrating light is generally to focus sunlight onto the target area through a reflector or to transmit and focus light through a transparent material. When using a photovoltaic panel concentrating adjustment device, the reflector or transparent material used for concentrating light is prone to dust accumulation, which affects the concentrating effect. Moreover, the existing tracking adjustment device is easily affected by factors such as wind and mechanical errors in actual operation, causing the solar incident angle to deviate from the axis of the concentrator and the light intensity distribution to be uneven. Among them, the controlled-release solar tracker can only track in one direction and cannot automatically track the movement of the sun between the Tropic of Cancer and the Tropic of Capricorn. It can only be re-aligned with the sunlight every once in a while, which has low accuracy. At the same time, the concentrating device relies on direct sunlight and cannot effectively utilize scattered light. Therefore, the power generation efficiency drops sharply under low light conditions such as cloudy or overcast days.

[0017] The technical effects and advantages of this application are as follows:

[0018] Compared with existing technologies, this concentrating adjustment device for photovoltaic modules requires the following steps during use: First, the device is assembled and installed. Then, the base is fixed in an open location. The bottom surface of the base has pre-drilled connection and limiting holes for securing the device. A rotating mechanism drives a support plate to rotate, which in turn rotates the concentrating adjustment mechanism and the solar photovoltaic panel on the upper surface of the support plate. The concentrating adjustment mechanism uses a second arc-shaped grid plate, a support limiting mechanism, and an angle adjustment mechanism to adjust the light reflection angle, allowing the solar photovoltaic panel to absorb reflected light. This structure solves the problem of… When adjusting the solar concentrator on a photovoltaic panel, the reflectors or transparent materials used for concentrating light are prone to dust accumulation, which affects the concentrating effect. In addition, existing tracking and adjustment devices are easily affected by factors such as wind and mechanical errors during actual operation, causing the solar incident angle to deviate from the axis of the concentrator and the light intensity distribution to be uneven. Among them, the controlled-release solar tracker can only track in one direction and cannot automatically track the sun's movement between the Tropic of Cancer and the Tropic of Capricorn. It can only realign with the sunlight every once in a while, which has low accuracy. At the same time, the concentrator device relies on direct sunlight and cannot effectively utilize scattered light. Therefore, the power generation efficiency drops sharply under low light conditions such as cloudy or overcast days.

[0019] Compared with existing technologies, this photovoltaic module concentrating adjustment device, in use, has a servo rotating platform in the rotating mechanism driving the support plate to rotate, and a sliding column installed on the bottom surface of the support plate moves along an arc groove carved on the upper surface of the base, thereby facilitating the change of the illumination angle. The rotation of the support plate changes the angle of the tripod, and the tripod is connected to a fixed frame via a fixed block and a fixed flange. The fixed frame is composed of a flange, a support rod, and a first arc-shaped grid plate, which facilitates the support and fixation of the concentrating adjustment mechanism, thereby adjusting the illumination angle to reflect light onto the solar photovoltaic panel on the bottom surface of the fixed plate. The fixed plate is fixedly connected to the fixed frame, and the fixed frame is fixed by the base, rotating mechanism, support plate, tripod, fixed block, and fixed flange, thereby fixing the concentrating adjustment mechanism, the fixed plate, and the solar photovoltaic panel, preventing the device from swaying due to wind force during operation, and increasing tracking accuracy.

[0020] Compared with the prior art, this concentrating adjustment device for photovoltaic modules supports and adjusts the angle of the supporting limiting mechanism and the angle adjustment mechanism through the second arc-shaped grid plate in the concentrating adjustment mechanism. The upper surface of the second arc-shaped grid plate is provided with several sets of supporting limiting mechanisms, thereby modularly arranging the device. The supporting limiting mechanism and the angle adjustment mechanism are quickly fixedly connected by magnetic attraction and quick fastening, which also facilitates the quick disassembly and installation of the device for maintenance.

[0021] Compared with existing technologies, this concentrating adjustment device for photovoltaic modules, in use, has a first limiting plate in the support and limiting mechanism that adjusts its tilt angle via four sets of support columns, a first electric telescopic rod, and a universal joint. Each first limiting plate is equipped with an angle sensor to detect and adjust its tilt angle in real time. Simultaneously, the support and limiting mechanism is connected to the first and second connecting components in the angle adjustment mechanism via a first and a second limiting assembly, using both fastening and magnetic connections. This allows for the assembly of the support and limiting mechanism and the angle adjustment mechanism, facilitating further adjustment of the angle of the second limiting plate in the angle adjustment mechanism. This allows the reflector on the second limiting plate to reflect light. The aluminum-based copper-clad laminate is connected to the second electric telescopic rod and the limiting columns via fixed columns and bearings. Activating the second electric telescopic rod changes the angle of the aluminum-based copper-clad laminate, thus facilitating light reflection. A reflector is installed on the side of the aluminum-based copper-clad laminate away from the aluminum-based copper-clad laminate. The reflector plate facilitates light reflection and heat dissipation via the aluminum-based copper-clad laminate. The reflector plate surface is coated with a nano-hydrophobic coating, reducing the frequency of manual cleaning. Photoelectric sensors are installed at both ends of the reflector plate to facilitate light reflection and absorption by the solar photovoltaic panel. This structure addresses the problems of dust accumulation on the reflector or transparent material used in photovoltaic panel concentrators, affecting the concentrating effect; existing tracking devices are susceptible to interference from wind and mechanical errors, causing the solar incident angle to deviate from the concentrator axis and resulting in uneven light intensity distribution; controlled-release solar trackers can only track in one direction and cannot automatically track the sun's movement between the Tropic of Cancer and Tropic of Capricorn, requiring periodic realigning with low accuracy; and concentrating devices rely on direct sunlight and cannot effectively utilize diffused light, leading to a sharp drop in power generation efficiency under low light conditions such as cloudy or overcast days.

[0022] Compared with existing technologies, this concentrating adjustment device for photovoltaic modules, in use, involves a first limiting plate being connected to a first limiting component and a second limiting component via a snap-fit ​​connection and magnetic connection with the first connecting component and the second connecting component on the bottom end face of the second limiting plate. When a third electric telescopic rod is activated, it causes the connecting block and connecting shaft to rise. Simultaneously, the first connecting rod and the connecting shaft rotate, and a sliding rod is slid along a sliding hole using a support, allowing the convex housing to insert into the inner side of the groove. The sliding rod then inserts into the inner side of the fixing hole, thus achieving limiting. Simultaneously, the trapezoidal protrusion engages with the trapezoidal groove, and the cobalt magnet and neodymium iron boron magnet form a magnetic attraction structure. This device facilitates the snap-fit ​​connection of the first and second limiting plates. The modular arrangement of the first and second limiting plates, along with the magnetic attraction and quick snap-fit ​​method, facilitates the rapid fixing and connection of the supporting limiting mechanism and the angle adjustment mechanism. It also facilitates subsequent quick disassembly and installation of the device for maintenance. Attached Figure Description

[0042] The first limiting plate 814 in the support limiting mechanism 81 is adjusted for tilt angle using four sets of support columns 811, a first electric telescopic rod 812, and a universal joint 813. Each set of first limiting plates 814 is equipped with an angle sensor to detect and adjust the tilt angle of the first limiting plate 814 in real time. The support limiting mechanism 81 uses a first limiting component 815 and a second limiting component 816 to engage and magnetically connect with the first connecting component 822 and the second connecting component 823 in the angle adjustment mechanism 82, further adjusting the angle change of the second limiting plate 821 in the angle adjustment mechanism 82, so that the reflector 828 on the second limiting plate 821 can reflect light. The aluminum-based copper-clad laminate 827 is connected to the second electric telescopic rod 825 and the limiting rod 824 via a fixed column 826 and a bearing. Activating the second electric telescopic rod 825 changes the angle of the aluminum-based copper-clad laminate 827, facilitating light reflection. A reflector 828 is installed on the side of the aluminum-based copper-clad laminate 827 away from the aluminum-based copper-clad laminate 827, which facilitates light reflection and heat dissipation using the aluminum-based copper-clad laminate 827. At the same time, the surface of the reflector 828 is coated with a nano-hydrophobic coating 829, reducing the frequency of manual cleaning. Photoelectric sensors are set at both ends of the reflector 828 to change the angle of the reflected light, ultimately facilitating the absorption of sunlight by the solar photovoltaic panel 10.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
