Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a flexible tracking support for a foldable mobile photovoltaic panel. Background Technology

[0002] A photovoltaic panel support is a metal or composite material frame that fixes or adjusts the solar panels at a certain tilt angle and orientation on the roof, ground, or water surface. It not only bears the weight of the components and resists wind and snow, but also allows the panel surface to receive sunlight to the maximum extent through tilt angle or tracking mechanism. It is the basic structure of "supporting the panel, positioning, and stabilizing the power generation" in the photovoltaic power generation system. The photovoltaic panel bracket is designed to be "foldable and mobile" so that the entire power generation system can be "packed into a suitcase". After folding, the volume is greatly reduced and the weight is light. With the bottom rollers or vehicle chassis, it can be quickly moved like a suitcase. After arriving at the destination, it can be unfolded and the angle adjusted in a few minutes to generate electricity. This saves manpower and time for repeated disassembly and assembly, and also reduces transportation costs. It is especially suitable for emergency rescue, field operations or temporary power supply scenarios, realizing "taking the power station with you". In emergency power supply after earthquakes, floods, and wildfires, time is of the essence and there are no foundation construction conditions. In such cases, photovoltaic panel supports may be folded or unfolded on sloping ground. If the center of gravity is always outside the supporting surface, the support will have too large an angle error after unfolding due to its own weight, or even overturn the whole. Therefore, a flexible tracking support for foldable mobile photovoltaic panels is proposed to address the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A flexible tracking bracket for a foldable mobile photovoltaic panel includes a flexible connecting component 1 and a photovoltaic bracket assembly 4. The upper end of the flexible connecting component 1 is rotatably connected to a telescopic adjustment component 2, and the upper end of the telescopic adjustment component 2 is fixedly connected to a correction auxiliary component 3. The correction auxiliary component 3 and the photovoltaic bracket assembly 4 are rotatably connected. The telescopic adjustment component 2 includes a rotating base 21, and the upper end of the rotating base 21 is rotatably connected to a screw cylinder 22. A screw rod 23 is spirally connected to the inner side of the screw cylinder 22. The correction auxiliary component 3 includes an extension plate 31, and the rear end of the extension plate 31 is fixedly connected to a first ear seat 32. The inner side of the first ear seat 32 is rotatably connected to a shaft column 33, and the bottom end is sequentially fixedly connected to a vertical rod 35 and an arc-shaped shell 36. An arc-shaped groove 37 is opened on the inner side of the arc-shaped shell 36. The photovoltaic bracket assembly 4 includes a photovoltaic bracket 41, the rear end of the photovoltaic bracket 41 is fixedly connected to a photovoltaic panel body 42, and the front end of the photovoltaic bracket 41 is fixedly connected to an arc-shaped metal arm 44. One end of the arc-shaped metal arm 44 is opened to a scale groove 45.

[0017] As a further implementation of this solution, the flexible connection component 1 includes a fixed base plate 11, with a rope 12 fixedly connected to the front end of the fixed base plate 11. The rope 12 is inserted into the interior of the perforated base plate 13, and a through hole is provided on the inner side of the perforated base plate 13. A metal pressure shell 14 is pressed and fixed to the outside of the rope 12. The rear end of the metal pressure shell 14 is attached to the front end of the perforated base plate 13. The upper end of the fixed base plate 11 is fixedly connected to the bottom end of the rotating base 21. The number of fixed base plates 11 corresponds one-to-one with the number of rotating bases 21. With the above settings, extension and locking can be completed in a few seconds, providing stable support without tools and significantly shortening the on-site deployment time. As a further implementation of this solution, the rear end of the extension plate 31 is fixedly connected to the arc-shaped metal arm 44. The extension plate 31 has a through hole near the screw 23. The arc-shaped groove 37 is arc-shaped. The inside of the arc-shaped groove 37 slides with the outside of the arc-shaped metal arm 44. The axis of the shaft column 33, the axis of the arc-shaped groove 37 and the axis of the arc-shaped metal arm 44 are on the same horizontal line. Through the above settings, the triple coaxial design ensures that the gravity reference is always perpendicular to the horizontal plane. The arc-shaped slide rail has extremely low friction, and the angle adjustment process is smooth and without jamming, ensuring that the best tilt angle can be locked instantly and accurately even on sloping terrain. As a further implementation of this solution, a screw hole is provided on the inner side of the screw barrel 22, and the upper end of the screw 23 is embedded in the through hole of the extension plate 31. The screw 23 is rotatably connected to the through hole of the extension plate 31 through a bearing. With the above settings, the screw fine adjustment mechanism can achieve fine adjustment, which can be completed by one person by hand. It saves effort and avoids tilting error caused by over-adjustment, thus improving the adjustment efficiency and accuracy. As a further implementation of this solution, the outer side of the shaft column 33 is rotatably connected to the inner side of the cylinder rod 34. The inner side of the cylinder rod 34 is a hollow structure, and a bearing is fixedly connected to the inner side of the cylinder rod 34. Both the left and right sides of the cylinder rod 34 are fixedly connected to the second ear seat 43. Multiple bearings are fixedly connected to the outer side of the shaft column 33. The shaft column 33 is rotatably connected to the second ear seat 43 through the bearings. With the above settings, folding is easier, rigidity is enhanced after unfolding, and the load is distributed by multiple bearings, avoiding local stress concentration.

[0018] Workflow: When placing the device on a sloping surface, first unfold the telescopic adjustment assembly 2 and the photovoltaic support assembly 4. At this time, the first lug 32 will rotate and connect to the outside of the shaft column 33 through the bearing. The cylinder rod 34 will also rotate to the outside of the shaft column 33 under the drive of the second lug 43. During the unfolding process of the telescopic adjustment assembly 2 and the photovoltaic support assembly 4, the rotating base 21 will drive the corresponding perforated bottom plate 13 to move. The perforated bottom plate 13 near the front end will slide on the outside of the rope 12. When unfolded to a certain angle, the rope 12 is squeezed by the metal pressure shell 14. The metal pressure shell 14 can prevent the rope 12 from moving inside the perforated bottom plate 13. At this time, the angle of the telescopic adjustment assembly 2 and the photovoltaic support assembly 4 is adjusted. Since the arc-shaped shell 36 has a certain gravity, under the action of gravity, the arc-shaped shell 36 will be vertically downward. Since the center of the arc-shaped groove 37 and the center of the arc-shaped metal arm 44 are on the same horizontal line, the scale groove 45 passing through the front end of the arc-shaped shell 36 and the arc-shaped shell 36 are connected. The scale groove 45 at the end is obtained by dividing the sum of the two scales by two. The scale groove 45 at the center of the arc shell 36 is gradually larger vertically from front to back. If the value of the scale groove 45 at the center of the arc shell 36 is small, it means that the photovoltaic bracket assembly 4 is tilted forward. If the value is large, it means that it is tilted backward. By rotating the screw 23, the distance between the screw 23 and the screw barrel 22 is controlled. If the photovoltaic bracket assembly 4 is tilted forward, the distance between the screw barrel 22 and the screw 23 becomes longer. By observing the arc metal arm 44 at the left end of the extension plate 31 and the arc metal arm 44 at the right end of the photovoltaic bracket 41, if the values ​​of the two scale grooves 45 are the same, it means that the angle between the photovoltaic bracket assembly 4 and the telescopic adjustment assembly 2 relative to the vertical rod 35 is the same, which is the optimal tilt angle and the highest stability. Based on the above principles, the device can control the photovoltaic bracket 41 within a certain tilt angle range to prevent the tilt angle error of the photovoltaic bracket assembly 4 from being too large after it is unfolded, which could lead to the overall overturning. It is suitable for use in situations where time is tight and there is no foundation for construction.
