Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to a jack for adjusting the angle of a photovoltaic panel. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device made up of solar cells encapsulated in series and parallel. Its core function is to directly convert solar radiation energy into electrical energy. The power generation efficiency of a PV panel is directly related to the amount of solar radiation received. Since the position of the sun in the sky changes constantly with the seasons and time, it is necessary to adjust the angle of the PV panel to make it as perpendicular to the sunlight as possible, thereby maximizing the light energy absorption efficiency.

[0003] In the prior art, photovoltaic panel support frames are generally fixed structures, with a few using movable support structures to adjust the photovoltaic panels. The existing adjustment methods generally use geared motors, electric push rods, and hydraulic cylinders to achieve the rotation of the photovoltaic panels. The electrical components have a precise structure, and their lifespan is difficult to guarantee in harsh environments such as high temperatures. Therefore, this utility model proposes a jack for adjusting the angle of photovoltaic panels to solve the above problems. Utility Model Content

[0017] Reference Figures 1-5A jack for adjusting the angle of a photovoltaic panel includes two lower connecting arms 1, spaced apart. An upper connecting arm 2 is located inside each lower connecting arm 1. The jack also includes an adjustment assembly for adjusting the angles of the upper connecting arm 2 and the lower connecting arm 1. The adjustment assembly is located on both sides of the lower connecting arm 1 and includes: a first fixing hole 7, which is respectively opened on both sides of the upper connecting arm 2 and the lower connecting arm 1; a connecting pipe 6 is located inside the upper connecting arm 2 on the left side; two first connecting posts 8 are fixedly installed on the outer circular wall of the connecting pipe 6; the first connecting posts 8 are movably sleeved with the first fixing holes 7; a threaded rod 10 is movably sleeved on the inner circular wall of the connecting pipe 6; a second connecting post 12 is located inside the upper connecting arm 2 on the right side; the second connecting post 12 is movably sleeved with the first fixing holes 7; a threaded hole 13 is opened on the outer circular wall of the second connecting post 12; the threaded hole 13 is threadedly connected to the threaded rod 10.

[0018] In this embodiment, two limiting rings 11 are fixedly installed on the outer circular wall of the threaded rod 10, respectively set at both ends of the connecting pipe 6, for limiting the threaded rod 10. A support column 3 is provided on one side of the lower connecting arm 1. A photovoltaic panel frame 9 is hinged to the top surface of the support column 3. A bottom connector 4 is hinged to one side of the support column 3. Connecting holes 16 are respectively opened on both sides of the bottom connector 4 and both sides of the lower connecting arm 1. Bolts 14 are movably sleeved on the inner circular wall of the connecting hole 16. Nuts 15 are threadedly connected to the outer circular wall of the bolts 14. A top connector 5 is hinged to the bottom surface of the photovoltaic panel frame 9. Connecting holes 16 are respectively opened on both sides of the top connector 5 and both sides of the upper connecting arm 2. Bolts 14 are movably sleeved on the inner circular wall of the connecting hole 16. Nuts 15 are threadedly connected to the outer circular wall of the bolts 14. A hexagonal column 18 is fixedly installed at one end of the threaded rod 10. A second fixing hole 17 is respectively opened on the outer wall of the hexagonal column 18 and the outer circular wall of the threaded rod 10.

[0019] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: By setting up support columns 3, the photovoltaic panel frame 9 is supported, and the top surface of the photovoltaic panel frame 9 is used to install photovoltaic panels. When it is necessary to adjust the angle of the photovoltaic panel, the hexagonal column 18 is turned with an electric wrench or other tools, which drives the threaded rod 10 to rotate. The rotating threaded rod 10 engages with the threaded hole 13, converting the rotational motion into linear motion, causing the second connecting column 12 to move closer to or away from the connecting pipe 6. Taking the second connecting column 12 moving away from the connecting pipe 6 as an example, the angle between the lower connecting arm 1 and the upper connecting arm 2 will gradually decrease, thereby driving the top connecting piece 5 and the bottom connecting piece 4 to move closer to each other, causing the bottom of the photovoltaic panel frame 9 to rotate downward; conversely, when the second connecting column 12 moves closer to the connecting pipe 6, the bottom of the photovoltaic panel frame 9 can be rotated upward, thus completing the adjustment of the photovoltaic panel's pitch angle.

[0020] When photovoltaic panels are installed side by side, the threaded rods 10 are connected together through the connecting rod and the second fixing hole 17. Then, the rotation of the outermost threaded rod 10 can drive the rotation of the parallel threaded rods 10, so as to realize the synchronous adjustment of the parallel photovoltaic panels. The connecting rod is similar to the universal joint drive shaft of an automobile. In order to ensure that the bolt 14 does not slip, an open pin should be used for limiting. The specific usage method is existing technology and will not be described in detail.

[0021] After adjustment, the self-locking structure formed by the threaded rod 10 and the threaded hole 13 can prevent self-rotation and ensure stable support of the photovoltaic panel. At the same time, the lower connecting arm 1, the upper connecting arm 2 and the threaded rod 10 form a triangular structure with high support strength. The entire adjustment process is convenient to operate, without complicated steps, and does not use mechanical equipment such as geared motors, electric push rods and hydraulic cylinders, making it difficult to damage. This reduces the production and use costs in the early and later stages and makes it highly practical.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
