[0002] Photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They consist of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0034] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0035] like Figure 1 As shown, as a drive linkage type single / dual axis photovoltaic tracking bracket of the present invention, it includes a fixed frame 10 arranged on the top of the rotating shaft 60, and a photovoltaic panel 30 is detachably arranged in the fixed frame 10. The fixed frame 10 is arranged as a cubic structure. A base frame 20 is fixed near the middle position of the bottom of the fixed frame 10, and a hydraulic telescopic rod 90 for adjusting the angle of the fixed frame 10 is fixed in the base frame 20. A rotating connecting shaft 11 is rotatably arranged at the bottom of the fixed frame 10, and the rotating connecting shaft 11 is placed on the top wall of one side of the base frame 20. The height of the rotating connecting shaft 11 is lower than the contact point between the hydraulic telescopic rod 90 and the fixed frame 10.

[0036] An arc-shaped protrusion 50 is fixed at the lower end of the fixed frame 10, and the arc-shaped protrusion 50 extends out of the bottom end of the fixed frame 10. A blocking plate 40 is fixed on the bottom frame 20;

[0037] The hydraulic telescopic rod 90 controls the fixed frame 10 to rotate. When the arc-shaped protrusion 50 does not contact the blocking plate 40, the fixed frame 10 rotates around the rotating connecting shaft 11.

[0038] The hydraulic telescopic rod 90 controls the fixed frame 10 to rotate. When the arc-shaped protrusion 50 contacts the blocking plate 40 , the fixed frame 10 rotates around the arc-shaped protrusion 50 , and the rotating connecting shaft 11 is separated from the base frame 20 .

[0039] Specifically, when the photovoltaic panel 30 is adjusted in angle, the hydraulic telescopic rod 90 works. In the initial state, the fixed frame 10 rotates around the rotating connecting shaft 11 with the rotating connecting shaft 11 as the support point. The angle of the fixed frame 10 can be adjusted in a small range through the support of the rotating connecting shaft 11. At the same time, this adjustment method can make the relative position of the fixed frame 10 with respect to the base frame 20 more stable, and the phenomenon of separation from the fixed frame 10 will not occur.

[0040] When the angle of the fixed frame 10 is continued to be adjusted by controlling the hydraulic telescopic rod 90, the arc-shaped protrusion 50 set at the end of the fixed frame 10 will contact the retaining plate 40, and the arc-shaped protrusion 50 is rotated relative to the retaining plate 40, so that the retaining plate 40 supports the arc-shaped protrusion 50, and the retaining plate 40 rotates around the contact point between the retaining plate 40 and the arc-shaped protrusion 50, so that the fixed frame 10 can be adjusted at a large angle. In this way, the adjustment range of the fixed frame 10 can be larger and the actual application range can be wider.

[0041] In some embodiments, Figure 2 As shown, the arc-shaped protrusion 50 is arranged at the bottom end of the fixing frame 10, and the outermost end of the arc-shaped protrusion 50 is located outside the extension line of the bottom end surface of the fixing frame 10. On the one hand, the arc-shaped protrusion 50 can be used as a fulcrum when the fixing frame 10 rotates. On the other hand, when the fixing frame 10 accidentally falls, the end of the fixing frame 10 located on one side of the arc-shaped protrusion 50 will be protected by the arc-shaped protrusion 50, thereby preventing the end of the fixing frame 10 from being damaged;

[0042] The arc-shaped protrusion 50 is located at the downwardly inclined end of the fixing frame 10. When the fixing frame 10 is installed on the photovoltaic panel 30, it is easy to fall accidentally. The fixing frame 10 on the side of the arc-shaped protrusion 50 will touch the ground first. The arc-shaped protrusion 50 can effectively prevent the fixing frame 10 from being damaged.

[0043] In some embodiments, Figure 3 As shown, the arc-shaped protrusion 50 is arranged at the bottom end of the fixed frame 10 and wraps the bottom end of the fixed frame 10, which can provide all-round protection for the downward inclined end of the fixed frame 10, reduce the impact force of the fixed frame 10 when it falls, and provide better protection for the fixed frame 10. At the same time, due to the wrapping arrangement, the overall volume of the arc-shaped protrusion 50 can be larger, and the contact area with the retaining plate 40 can be larger. During the rotation of the fixed frame 10, the supporting point of the arc-shaped protrusion 50 can withstand a larger weight, and its stability during rotation is higher.

[0044] In some embodiments, Figure 2-4 As shown, the retaining plate 40 is configured as a single-bending plate-shaped structure, and the angle of the turning point of the retaining plate 40 is an obtuse angle. An arc-shaped groove 41 for clamping the arc-shaped protrusion 50 is provided at the turning point of the retaining plate 40. By setting the retaining plate 40 at an obtuse angle, when the arc-shaped protrusion 50 rotates around the retaining plate 40, there is enough space on the retaining plate 40 for the arc-shaped protrusion 50 to rotate. At the same time, the rotation range of the arc-shaped protrusion 50 can be larger, and the adjustable angle of the fixed frame 10 can be larger.

[0045] In some embodiments, Figure 5-6 As shown, a first connecting block 12 and a second connecting block 13 are provided at both sides of the bottom center of the fixing frame 10, and the first connecting block 12 and the second connecting block 13 can be detachably connected with the through-piece 80;

[0046] When multiple fixing frames 10 need to be linked, the penetration member 80 penetrates and connects the first connection block 12 and the second connection block 13 provided at the bottom of different fixing frames 10 .

[0047] Through this structural setting, a synchronous linkage state can be generated between multiple fixed frames 10, so that the angle of the photovoltaic panels 30 on the multiple fixed frames 10 can be adjusted. The two penetration members 80 are respectively penetrated in the first connecting block 12 and the second connecting block 13, which can make the connection position between two adjacent fixed frames 10 more stable.

[0048] The first connection block 12 and the second connection block 13 have the same structure, both including a block body 121 and a cross through hole 122. The cross through holes 122 are arranged in a normal triangular distribution and penetrate the block body 121, so that the three cross through shafts 82 can be connected as a whole. When the two fixing frames 10 are connected, the connection position is more stable.

[0049] The penetration member 80 includes a fixed disk 81 , a cross penetration shaft 82 and a fixed rod 83 . The fixed disk 81 is fixed to the end of the cross penetration shaft 82 . The cross penetration shaft 82 corresponds to the cross through hole 122 one by one. The fixed disks 81 are fixedly connected by the fixed rod 83 .

[0050] The setting of the penetration member 80 through this structural setting can, on the one hand, make the connection position between the penetration member 80 and the first connecting block 12 or the second connecting block 13 more stable, and the position of the penetration member 80 will not rotate relative to each other after penetration, so that the placement position of the penetration member 80 is more stable and the actual application effect is better.

[0051] In some embodiments, Figure 2-3 As shown, a connecting rope 84 connected to the base frame 20 is fixed at the bottom of the fixed plate 81, and the length of the connecting rope 84 is greater than the distance between the fixed plate 81 and the bottom of the base frame 20. Through the setting of the connecting rope 84, on the one hand, the penetration member 80 will not be separated from the base frame 20 when in use, and on the other hand, the fixed plate 81 can be determined to rotate to the maximum angle to avoid excessive rotation and cause the fixed frame 10 to be separated, and the actual application effect is better.

[0052] In some embodiments, Figure 4 As shown, a protective seat 103 is fixed to the top of the fixed frame 10, and the protective seat 103 wraps the top of the fixed frame 10. A pull rope 102 is connected to the protective seat 103. A guide wheel 101 is fixed to the base frame 20. The pull rope 102 is set around the guide wheel 101, and the hydraulic telescopic rod 90 and the fixed frame 10 are rotatably connected.

[0053] Specifically, the user pulls the pull rope 102 to make the fixed frame 10 rotate in the opposite direction around the hydraulic telescopic rod 90, so that the fixed frame 10 can be adjusted to more angles. When the angle adjustment of the fixed frame 10 is completed, the pull rope 102 is fixed to the base frame 20 to limit the position of the fixed frame 10. In addition, by setting the protective seat 103 and cooperating with the setting of the arc-shaped protrusion 50, the fixed frame 10 can be better protected during transportation.

[0054] By setting the pull rope 102, the position of the fixing frame 10 can be auxiliary limited from the upper side during the forward rotation of the fixing frame 10, so that the position of the fixing frame 10 after rotation is more stable and the actual application effect is better.

[0055] like Figure 1 As shown, the bottom of the base frame 20 is fixedly connected to a rotating shaft 60, and the rotating shaft 60 is rotatably set on a fixed base 70. The fixed base 70 is provided with a motor for driving the rotating shaft 60 to rotate. When the motor is working, it can drive the rotating shaft 60 to rotate, thereby causing the base frame 20 to rotate accordingly, and the photovoltaic panel 30 in the fixed frame 10 can be adjusted in the horizontal direction.

[0056] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
