There is a large gap between the flat single-axis tracking brackets of adjacent arrays, and the flat single-axis tracking brackets of adjacent arrays need to be connected by a bridging structure. There is also a gap at the internal driving position of a single flat single-axis tracking bracket, which also needs to be connected by a bridging structure. Among them, a connecting frame is fixedly installed around the photovoltaic panel, and the existing bridging structure is installed at the end of the connecting frame (which is also the end of the flat single-axis tracking bracket), which has the defects of much material and high cost.

[0003] In view of this, the inventor of the present invention has actively studied and improved the above-mentioned shortcomings and inconveniences, and finally developed and designed the present invention. Summary of the invention

[0008] The photovoltaic panels are divided into two rows and are arranged at intervals on both sides of the corresponding flat single-axis tracking brackets. A mounting plate chamber is fixedly provided under the main body. The mounting plate chamber contains a linkage structure for a motor to drive the travel shaft to rotate. The travel shaft can be rotatably passed through the mounting plate chamber. At least one limiting wheel is fixedly provided on the lower surface of the mounting plate chamber. The limiting wheel can be rotatably accommodated in the interval between the two rows of photovoltaic panels.

[0009] The bridging structure is a flexible bridge structure.

[0010] The flexible bridge structure is a telescopic sleeve member, which includes an outer tube and an inner tube that can be extended into the outer tube. The end of the outer tube away from the inner tube can be rotatably fixed on a first mounting seat, and the end of the inner tube away from the outer tube can be rotatably fixed on a second mounting seat. A mounting rod is fixed on the purlins of two adjacent horizontal single-axis tracking brackets, and the first mounting seat and the second mounting seat are fixed on the corresponding mounting rods.

[0011] The photovoltaic panels are divided into two rows and arranged at intervals on both sides of the corresponding flat single-axis tracking brackets.
