Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a solar dual-axis tracking bracket. Background Technology

[0002] A dual-axis solar tracking system is a photovoltaic (PV) module support structure capable of simultaneously tracking changes in the sun's azimuth and altitude angles. Its working principle involves rotating along two axes in two directions, allowing the PV modules to adjust their angles in real time to maintain perpendicularity to sunlight, thereby optimizing the angle of incidence and maximizing solar radiation reception. Compared to fixed mounting systems, dual-axis tracking systems significantly increase power generation when supporting solar PV panels; however, their cost is also relatively high, with larger initial investment and footprint, as well as higher maintenance costs, making them less cost-effective for large-scale ground-mounted power plants.

[0003] Currently, existing dual-axis tracking brackets for solar photovoltaic panels integrate axial movement into a single-support pile base to achieve dual-axis motion. This requires the use of a hydraulic pushing mechanism, resulting in higher costs. Compared to the cost increase brought by single-axis tracking brackets, the benefit ratio of increased revenue is poor, leading to fewer large-scale applications of superior dual-axis tracking brackets. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a solar dual-axis tracking bracket, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the bottom support arm has a first bearing inserted through both sides, and the bottom support arm provides rotatable mounting to the X-axis through the first bearing; the top support arm has a second bearing inserted through the middle, and the top support arm provides rotatable mounting to the Y-axis through the second bearing; the photovoltaic panel loading frame includes a photovoltaic panel loading plate body and a photovoltaic panel loading through hole, the photovoltaic panel loading through hole is longitudinally opened at the edge of the photovoltaic panel loading plate body, and the photovoltaic panel loading plate body has a lightweight groove group longitudinally opened on the surface of the plate.

[0008] Preferably, the base cylinder includes a supporting cylinder pile and a reinforcing corner plate, the reinforcing corner plate being welded and fixed to the bottom of the surface of the supporting cylinder pile; the loading foot includes a base pile mounting plate and a base pile mounting hole, the supporting cylinder pile and the reinforcing corner plate being welded and installed on the top surface of the base pile mounting plate, and the base pile mounting hole being longitudinally opened at the corner of the base pile mounting plate.

[0009] Preferably, the motor assembly includes a servo motor and a reducer, and the output end of the servo motor is driven by the reducer to drive the X-axis or Y-axis.

[0010] Preferably, the cross-shaped carrier plate frame is a cross-shaped plate structure, and the number of reinforcing diagonal ribs is four, with the four reinforcing diagonal ribs respectively surrounding and having their ends connected and fixed to the corners of the bottom surface of the cross-shaped carrier plate frame.

[0011] Preferably, the lightweight groove assembly includes a first through groove and a second through groove, the second through groove being disposed near the side end of the photovoltaic panel mounting plate, and the first through groove being disposed in the middle of the photovoltaic panel mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This novel dual-axis solar tracking bracket utilizes two base cylinders as the support structure. The bracket employs a layered design for the shafts controlling the movement of the two bearings—the X and Y axes—each driven by a separate motor. The upper Y-axis is connected to a cross-shaped support structure, ensuring more even distribution of stress. Reinforcing ribs at the bottom of the cross-shaped support structure enhance structural strength and prevent deformation. By using two base cylinders as the support, stable axial movement can be achieved solely through motor-driven, layered X and Y axes. Compared to traditional dual-axis tracking brackets with hydraulic systems, this design reduces costs, simplifies the structure, and lowers maintenance. It maintains the power generation efficiency of the dual-axis tracking bracket while reducing equipment costs, thus improving its economic viability for large-scale applications.
