Traction type adjustable photovoltaic support with reflector

Abstract

The traction type adjustable photovoltaic support is characterized in that the long edges of the upper ends of a photovoltaic module array and a reflector array are hinged to a rotating shaft, the two ends of the rotating shaft are fixed to a cross beam, each stand column is sleeved with a sliding block, a rocker I is hinged to the lower end face of the photovoltaic module array, and the other end of the rocker I is hinged to the sliding block; similarly, a rocker II is hinged to the lower end face of the reflector array, and the other end of the rocker II is hinged to the sliding block. One end of a steel wire rope I is fixed to the cross beam, and the other end of the steel wire rope I sequentially winds around the movable pulleys and then winds around the fixed pulley II to be connected to the hand cranking device. On the basis of a traditional photovoltaic array, light is reflected to a photovoltaic panel in the back row through a reflector, the generating capacity of a photovoltaic system is improved, and stepless adjustment and differential adjustment of the inclination angles of a photovoltaic module array and a reflector array are achieved through a gear train traction system and a differential sleeve. The method is high in resource utilization rate, good in terrain adaptability and especially suitable for complex terrain photovoltaic projects.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation equipment, in particular to a traction-type adjustable photovoltaic support with a reflector. Background technique [0002] Due to the low energy density of solar energy, in order to achieve large-scale energy output, the area occupied by photovoltaic power plants is often very large. Moreover, in order to avoid mutual shading of the front and rear photovoltaic arrays when the sun altitude angle is low, the photovoltaic arrays need to ensure a certain distance. According to the requirements of relevant regulations and specifications, the calculation of the spacing of the photovoltaic square array should be based on the winter solstice when the solar altitude angle is the lowest and still ensure that the sunshine time on the modules has 6 hours of sunshine. This distance is one of the main reasons for the low land utilization rate of photovoltaic power plants. Moreover, the ...

Problems solved by technology

This solution uses a hoist to adjust the photovoltaic array. The system is complicated and the cost is high. The reflector installed on the lower edge of the module has no reliable support, and its inclination cannot be adjusted, so the flexibility is poor.
