Technical Field
[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic module junction box. Background Technology
[0002] Photovoltaic modules are devices that convert solar energy into electrical energy. Junction boxes are installed on photovoltaic modules and their function is to output and combine the current generated by each photovoltaic module to the system control box. In addition, junction boxes also play a role in protecting solar photovoltaic modules. Junction boxes are equipped with bypass protection components that are connected to the battery strings in the photovoltaic modules. When a battery string is damaged or a hot spot effect is caused by shading, the faulty battery string can be bypassed from the photovoltaic system to avoid adverse effects on the entire photovoltaic system.
[0003] Current photovoltaic (PV) module junction boxes can only bypass the faulty PV module or its battery string from the PV power generation system when a PV module fails. However, system maintenance personnel cannot visually identify faulty PV modules during inspections, which makes system maintenance difficult. Later, some junction boxes emerged that can display the operating status of PV modules. By installing a display screen on the junction box, maintenance personnel can clearly obtain the current status of the PV modules, thus facilitating PV module repair. However, in actual use... Figure 1 and Figure 2 As shown, since the photovoltaic module 3 is tilted and the photovoltaic module is spliced from multiple pieces, the photovoltaic module junction box 1 is also tilted, and the display screen 22 is also tilted. As a result, during actual inspection, some of the display screens on the photovoltaic modules cannot be seen quickly and intuitively, which causes inconvenience in use. Utility Model Content
[0004] The purpose of this invention is to provide a photovoltaic module junction box that solves the aforementioned problems existing in current photovoltaic module junction boxes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A photovoltaic module junction box includes a box body and a display component. The box body is used to install on the back of the photovoltaic module. The display component includes a rotating frame and a display screen. The upper end of the rotating frame is hinged to the upper part of the box body. The display screen is disposed at the lower part of the rotating frame and located below the box body. The display screen is configured such that when the box body is tilted with the photovoltaic module, the display screen rotates with the rotating frame to make the display screen vertically positioned.
[0007] Furthermore, the rotating frame includes a panel and a rotating rod. The rotating rod is disposed on both sides of the upper end of the panel. A pivot is provided at the upper end of the rotating rod. A rotating hole is provided on the side of the upper part of the box body. The pivot is located in the rotating hole. The panel is configured such that when the rotating rod does not tilt with the box body, the panel is located below the box body. The display screen is disposed on the panel.
[0008] Furthermore, the rotating hole is located in the middle of the side of the box body, between the front and back of the box body, and the thickness of the rotating rod is less than the thickness of the box body.
[0009] Furthermore, the panel is provided with a through groove, the rotating shaft is hollow, the through groove is connected to the rotating shaft, and a cover plate is provided on the back of the panel.
[0010] Furthermore, a counterweight is provided in the cable channel near the lower end of the panel.
[0011] Furthermore, the inner side of the rotating rod is provided with a positioning groove, and the side of the box is provided with a corresponding positioning protrusion.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] The photovoltaic module junction box of this utility model, such as Figure 3 - Figure 6 As shown, it includes a housing 1 and a display component 2. The housing 1 is used to install on the back of the photovoltaic module 3, and the display component 2 is used to display the working status of the photovoltaic module 3, which is convenient for maintenance personnel to inspect.
[0024] Figure 4 - Figure 6 As shown, the display component 2 specifically includes a rotating frame 21 and a display screen 22. The upper end of the rotating frame 21 is hinged to a rotating hole 11 provided on the upper side of the housing 1 via a pivot 211, allowing the rotating frame 21 to rotate relative to the housing 1. The display screen 22 is located at the lower part of the rotating frame 21 and below the housing 1. When the housing 1 tilts with the photovoltaic module 3, the display screen 22 rotates with the rotating frame 21, ensuring that the display screen 22 always remains vertical, facilitating observation by maintenance personnel.
[0025] Figure 5 and Figure 6 As shown, the rotating frame 21 further includes a panel 212 and a rotating rod 213. The rotating rod 213 is disposed on both sides of the upper end of the panel 212, and its thickness is less than the thickness of the box body 1. The upper end of the rotating rod 213 is provided with a rotating shaft 211, which is located in the rotating hole 11 in the middle of the upper side of the box body 1, so that the rotating frame does not protrude from the box body 1 when it is not rotating, thereby facilitating the stacking and transportation of photovoltaic modules.
[0026] To further enhance the display effect and stability of the display screen 22, a cable routing channel 214 is provided in the panel 212 for cable routing. The hinge 211 is hollow and communicates with the cable routing channel 214 to facilitate the insertion and exit of cables. A cover plate 215 is also provided on the back of the panel 212 to close the cable routing channel 214 and protect the cables from damage.
[0027] A counterweight 216 is also provided in the cable channel 214 near the lower end of the panel 212 to increase the weight of the lower part of the rotating frame 21, so that the display screen 22 is more stable and less prone to shaking during rotation.
[0028] Furthermore, to ensure that the rotating frame 21 remains stably positioned below the housing 1 when not tilted, the inner side of the rotating rod 213 is provided with a positioning groove 217, and the side of the housing 1 is correspondingly provided with a positioning protrusion 12. Through the cooperation of the positioning protrusion 12 and the positioning groove 217, the rotating rod 213 is engaged with the housing 1 when not tilted, ensuring the stability of the display component 2.
[0029] In practical applications, when the photovoltaic module 3 is tilted, the housing 1 tilts along with it. At this time, since the display screen 22 is hinged to the housing 1 via the rotating frame 21, the display screen 22 can rotate with the rotating frame 21 to maintain a vertical orientation. This allows maintenance personnel to quickly and intuitively observe the photovoltaic module's operating status information displayed on the display screen 22 during inspections, improving inspection efficiency and accuracy.
[0030] In summary, the photovoltaic module junction box of this utility model, through its unique rotating frame and display screen design, solves the problem that the display screen cannot be quickly and intuitively seen when the traditional junction box is tilted, thereby improving the operation and maintenance efficiency and reliability of the photovoltaic system.
[0031] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
