Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a photovoltaic panel arrangement frame. Background Art

[0002] Solar energy is a clean energy source. The solar photovoltaic power generation system uses the photovoltaic effect of solar cell semiconductors to directly convert the thermal energy of solar radiation into electrical energy. It is a new type of power generation system and is widely used in the field of lighting. Existing solar photovoltaic power generation systems generally use a large number of photovoltaic panels to convert solar energy. The installation method of photovoltaic panels is generally to integrate several photovoltaic panels on a common frame to form a large number of photovoltaic panel combinations.

[0003] However, the tilt angle of the arrangement bracket of some traditional solutions is fixed, so the illumination time of the photovoltaic panels is limited, and foreign matter will accumulate on the surface of the photovoltaic panels after long-term use, affecting the lighting effect and conversion efficiency.

[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only for understanding the background of the concept of the present application and may contain information that does not constitute the prior art. Summary of the invention

[0005] Based on this, it is necessary to provide a photovoltaic panel arrangement rack to address the above problems.

[0010] a second lifting device, wherein the bottom of the second lifting device is arranged on the base, the top of the second lifting device is connected to the bottom surface of the placement plate, and the first lifting device and the second lifting device are arranged at intervals and are respectively connected to two sides of the placement plate;

[0011] A driving device, wherein the driving device is arranged on the base and can move relative to the base to a first position and a second position; when in the first position, the driving device is transmission-connected with the first lifting device and drives the first lifting device to perform lifting motion to adjust the inclination angle of the placement plate; when in the second position, the driving device is transmission-connected with the second lifting device and drives the second lifting device to perform lifting motion to adjust the inclination angle of the placement plate.
