Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets, and in particular relates to a tracking type photovoltaic panel bracket. Background Art

[0002] Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel. Photovoltaic brackets mainly include fixed brackets and tracking brackets. Fixed brackets have a simple structure, low operating and maintenance costs, but low power generation and efficiency; tracking brackets can automatically adjust the working angle so that the photovoltaic panels carried on them face the sun as much as possible, so that the photovoltaic panels can fully receive solar radiation energy, thereby increasing power generation.

[0003] According to different structural systems, tracking brackets are mainly divided into flat single-axis tracking brackets, inclined single-axis tracking brackets and dual-axis tracking brackets. Single-axis photovoltaic tracking brackets usually have a rotating main axis, and then photovoltaic panels are installed on the rotating main axis to track the movement of the sun. Among them, the one with the rotating main axis parallel to the ground is called a flat single-axis, and the one with an angle between the rotating main axis and the ground is called an inclined single-axis. The inclined single-axis tracking bracket is one of the most commonly used photovoltaic array brackets. Because the bracket can track the changes in the solar azimuth angle during the day, the total annual power generation of photovoltaic modules using this bracket is 15%-20% higher than the total annual power generation of photovoltaic modules using the best fixed tilt bracket.

[0004] However, the above-mentioned traditional tracking brackets are relatively inflexible and can only be fixed at a fixed inclination angle to fix the photovoltaic panel. When the photovoltaic panel rotates around the axis, it cannot always be perpendicular to the sunlight, and the power generation efficiency of the photovoltaic panel cannot be maximized. In addition, when the angle of the photovoltaic panel installation frame changes, if the distance between adjacent photovoltaic panels is too small, it is easy to cause the two adjacent photovoltaic panel installation frames to overlap, affecting the light power generation efficiency. Therefore, it is urgent to design a tracking photovoltaic panel bracket to solve the above problems. Utility Model Content

[0031] In this embodiment, an extension plate is connected to one side of the support structure 2, and a plurality of photosensors are connected to the outer wall of the extension plate. A controller is provided on one side of the support structure 2, and the controller is electrically connected to the photosensors.

[0032] Working principle:

[0033] In the actual working process, the first driving member 3-1 can adjust the photovoltaic panel 6 to rotate in the north-south direction. The extension of the piston rod of the first driving member 3-1 can drive the photovoltaic panel 6 to flip upward. Conversely, the retraction of the piston rod of the first driving member 3-1 can drive the photovoltaic panel 6 to flip downward. Under the action of the first driving member 3-1, the rotation angle range of the photovoltaic panel 6 in the north-south direction is 0 to 45°; the second driving member 3-9 can adjust the photovoltaic panel 6 to rotate in the east-west direction. The extension of the piston rod of the second driving member 3-9 can drive the photovoltaic panel 6 to flip westward. Conversely, the retraction of the piston rod of the second driving member 3-9 can drive the photovoltaic panel 6 to flip eastward. Under the action of the second driving member 3-9, the rotation angle range of the photovoltaic panel 6 in the east-west direction is negative 45° to positive 45°. Through the above-mentioned settings, the photovoltaic panel 6 can track sunlight in real time, so that sunlight can be vertically irradiated on the photovoltaic panel 6, thereby increasing the efficiency of photovoltaic power generation;

[0034] In the actual working process, in order to improve the efficiency of photovoltaic power generation, the spacing between adjacent photovoltaic panels is generally not large. Since the flipping and rotation angle range of the photovoltaic panel 6 in the east-west direction is large, the two adjacent groups of photovoltaic panels 6 will overlap when the photovoltaic panel 6 rotates in the east-west direction, affecting the lighting efficiency. Therefore, in order to avoid the overlap of the two adjacent photovoltaic panels 6, after the photovoltaic panel 6 rotates in the east-west direction, the drive motor 5-5 is started, and under the action of the moving transmission pair 5-4, the drive screw 5-2 is driven to rotate, and then the front transverse seat 5-7 and the rear transverse seat 5-8 are driven to move a certain distance synchronously along the linear guide rail 5-3, thereby avoiding the overlap between the two adjacent groups of photovoltaic panels 6 and affecting the lighting efficiency.
