Sun-chasing device applied to solar street lamp

Abstract

The invention discloses a sun-chasing device applied to a solar street lamp, and belongs to the field of solar power generation devices. The sun-chasing device structurally comprises a rotating support and a solar cell panel, wherein the rotating support is hinged to a lamp pole, and the solar cell panel is arranged on the rotating support. The sun-chasing device is characterized in that with the help of a rotating driving mechanism, the rotating support forms a horizontal rotation driving structure, and with the help of combined limiting of a horizontal movement mechanism and an angle adjusting and limiting mechanism, the solar cell panel forms a linkage type perpendicular rotation adjusting structure. Through a combined limiting device composed of the horizontal rotation driving structure and the linkage type perpendicular rotation adjusting structure, the alignment angle and light-receiving angle of the solar cell panel can be adjusted in real time according to the sun motion, it is ensured that the solar cell panel works at the maximum photoelectric conversion efficiency, and the sun-chasing device is simple in structure and high in reliability.

Description

technical field [0001] The invention belongs to the field of solar power generation devices, and in particular relates to a solar tracking device applied to solar street lamps. Background technique [0002] With the development of science and technology, energy saving and environmental protection have become the goal pursued by various products today. Street lamps, as widely used lighting appliances, not only consume a huge amount, but also have high power, long working hours, and amazing power consumption. Erecting long-distance pipelines requires high investment costs and cumbersome maintenance, so solar street lights appear on the market. [0003] At present, in the structure of solar street lamps, there are mainly two types of solar panel power generation structures: (1) The solar panel is set at a fixed pitch angle and rotates with the direction of the sun, which is characterized by simple structure and low manufacturing cost. , but the photoelectric conversion efficie...

[0003] At present, in the structure of solar street lamps, there are mainly two types of solar panel power generation structures: (1) The solar panel is set to a fixed pitch angle and rotates with the direction of the sun, which is characterized by simple structure and low manufacturing cost. , but the photoelectric conversion efficiency per unit area of ​​the solar panel is low, and it cannot achieve the purpose of energy saving; (2) According to the direction of the sun's movement and the angle of incidence of sunlight, the way to adjust the posture of the solar panel in real time is characterized by the solar panel The photoelectric conversion efficiency per unit area is high, which can achieve the purpose of energy saving, but this kind of structure is complicated, and it needs to use two driving motors to drive two rotating shafts to realize its function. The manufacturing cost is too high for street lamps with huge usage , the reason is that the electricity usage fee saved by photoelectric conversion cannot fully offset its manufacturing cost, which is uneconomical
