Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets, and in particular relates to a safety locking device for a photovoltaic bracket. Background Art

[0002] Photovoltaic brackets refer to metal structures used to support and install solar photovoltaic modules. Their main function is to fix solar panels and orient them correctly toward the sunlight to maximize the absorption of light energy. Photovoltaic brackets are usually made of weather-resistant and corrosion-resistant materials, such as galvanized steel, aluminum alloy, etc.

[0003] When adjusting the inclination angle of a photovoltaic bracket, a self-locking motor is usually used to constrain its angle. However, the self-locking motor will automatically lock after a power outage, so additional control or unlocking steps may be required during the restart process, making the startup process relatively complicated.

DETAILED DESCRIPTION

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the fixed frame 1 and the rotating frame 2 are hinged to each other, and two symmetrically distributed control blocks 5 are fixedly connected to the inner sides of the fixed frame 1 and the rotating frame 2, and an adjustment structure is rotatably connected between the two control blocks 5, and the adjustment structure is provided with an adjustment rod 6, and there are two adjustment rods 6, and the ends of the two adjustment rods 6 away from each other are rotatably connected to the connecting shaft 7, and the end of the adjustment rod 6 away from the connecting shaft 7 is rotatably connected to the control shaft 8, and the two adjustment rods 6 are connected to each other through the control shaft 8, a screw rod 9 is rotatably connected to the inside of one side of the control shaft 8, and a screw sleeve 10 is threadedly connected to the outside of the screw rod 9, a rotating rod 11 is fixedly connected to the end of the screw sleeve 10 away from the screw rod 9, and a rotating positioning block 12 is rotatably connected to the outside of the rotating rod 11, and the end of the adjusting rod 6 is rotatably connected to the control block 5 through the connecting shaft 7, and a scissor-type structure is formed between the two adjusting rods 6;

[0021] First, the rotating rod 11 is connected to the driving device so that the driving device can drive the rotating rod 11 to rotate. When the rotating rod 11 rotates, the rotating rod 11 will rotate inside the rotating positioning block 12. The rotation of the rotating rod 11 drives the screw sleeve 10 to rotate outside the screw rod 9. When the screw sleeve 10 rotates outside the screw rod 9, the screw sleeve 10 will drive the screw rod 9 to move inside the screw sleeve 10, thereby adjusting the distance between the control shaft 8 and the rotating rod 11, and further making the control shaft 8 drive the two adjusting rods 6 to rotate around the connecting shaft 7, thereby adjusting the angle between the two adjusting rods 6, and realizing the adjustment of the angle between the fixed frame 1 and the rotating frame 2. The shape design of the thread and the effect of friction between the screw rod 9 and the screw sleeve 10 enable the screw rod 9 or the screw sleeve 10 to maintain a stable position without external force, and will not loosen or slide by itself. This self-locking performance can effectively prevent loosening caused by external factors such as vibration and load.

[0023] By setting up multiple fixing rings 15, the photovoltaic panel can be connected to the rotating frame 2 by bolts passing through the inside of the fixing rings 15. Through the multiple connecting holes provided in the fixing plate 13, the fixing frame 1 can be connected to the multiple connecting holes of the fixing plate 13 by bolts, so that the fixing frame 1 and the supporting structure are connected to each other.
