Description

Technical Field

[0001] This invention belongs to the field of solar power generation device technology, specifically to a reflective solar power generation device and method. Background Technology

[0002] Solar power generation devices are powered by sunlight. However, the efficiency of solar energy in converting sunlight is limited, requiring a sufficient area to receive light. To avoid shading interference between photovoltaic panels, traditional solar power generation devices only install one photovoltaic panel per unit, and the photovoltaic panel is installed at a slight slope, requiring a large area. As a result, existing photovoltaic power generation devices generally suffer from the disadvantages of large site area and low power generation efficiency. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a reflective solar power generation device and method, which solves the problems of large site area occupation and low power generation efficiency that are common in existing photovoltaic power generation equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a reflective solar power generation device, comprising a vertically arranged column, a photovoltaic panel assembly sleeved on the column, the photovoltaic panel assembly having a polyhedral structure, the distance between the sidewall of the polyhedral structure and the column being adjustable, and a reflector being provided at the lower part of the photovoltaic panel assembly, the height of the reflector being adjustable.

[0005] Furthermore, the photovoltaic panel assembly includes a plurality of first photovoltaic panels inclined around the column and a second photovoltaic panel horizontally disposed on the top of the column. The second photovoltaic panel is polygonal, and the number of first photovoltaic panels may be greater than, equal to or less than the number of sides of the second photovoltaic panel.

[0006] Furthermore, the bottom ends of the plurality of first photovoltaic panels are all hinged to the side wall of the column, and the top ends of the plurality of first photovoltaic panels are all connected to the top of the column through an adjusting rod, the length of which is adjustable.

[0007] Furthermore, two adjustment rods are symmetrically connected to the top of the first photovoltaic panel, and the two adjustment rods are distributed in a V-shape.

[0008] Furthermore, the adjusting rod includes two sets of ball joint connecting rods and a screw. The two ends of the screw are symmetrically provided with threads. The two sets of ball joint connecting rods are respectively threaded to the two ends of the screw. The rod seats on the two sets of ball joint connecting rods away from the screw are respectively connected to the first photovoltaic panel and the column.

[0009] Furthermore, the first photovoltaic panel is arranged in an inverted trapezoidal shape.

[0010] Furthermore, the reflector has a bowl-shaped structure with its opening facing upwards, and a collar is provided at the bottom of the reflector. Both the reflector and the collar are sleeved on the column.

[0011] Furthermore, the column has multiple insertion holes evenly distributed along the axial direction. The insertion holes penetrate the column radially, and the collar is fixed to the insertion holes at different heights on the column by bolts to adjust the height of the reflector.

[0012] Furthermore, a base is provided at the bottom end of the column.

[0013] The present invention also provides a method for using a reflective solar power generation device. During operation, the top of the photovoltaic panel group directly receives sunlight. By adjusting the distance between the side wall of the photovoltaic panel group and the column, as well as the height of the reflector, the side wall of the photovoltaic panel group receives sunlight from the oblique direction, diffuse reflection from the air, and reflection from the reflector.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention provides a reflective solar power generation device. By setting up a photovoltaic panel array with a polyhedral structure, it can simultaneously receive direct, oblique, and diffusely reflected sunlight. By adjusting the distance between the sidewalls of the polyhedral structure and the column, as well as the height of the reflector, the optimal light collection rate can be achieved, improving the utilization rate of nearby sunlight by the power generation device. Furthermore, the power generation device of this invention has a compact shape and higher space and light utilization rate than existing photovoltaic equipment, effectively solving the problems of large site area occupation and low power generation efficiency that are common in existing photovoltaic power generation equipment.

[0016] The power generation device of the present invention can adjust the tilt angle of the first photovoltaic panel by rotating a screw with symmetrical threads, which causes the ball joints at both ends of the screw to move away or closer simultaneously. Combined with the height adjustment of the reflector, the device can be easily adjusted to the optimal light collection rate. Attached Figure Description
