Photovoltaic power generation sun tracking device

Abstract

The invention relates to a photovoltaic power generation sun tracking device. The photovoltaic power generation sun tracking device comprises a photovoltaic panel, a supporting base, a circumferentialrotating part and a horizontal elevation angle adjusting part, wherein the circumferential rotating part comprises a turntable bearing and a motor; the turntable bearing is horizontally arranged right above the supporting base and performs circumferential rotating motion around the central axis under the action of the driving force of the motor; the horizontal elevation angle adjusting part comprises a base plate, a pitching plate, a connecting plate and a dragging unit; the substrate synchronously and circumferentially rotates along with the circumferential rotating part; the pitching plateis used for placing and fixing the photovoltaic panel and is hinged to the substrate; one end of the connecting plate is hinged to the pitching plate, and the other end of the connecting plate is driven by the dragging unit to conduct directional displacement motion. Therefore, the direction of the photovoltaic panel can be conveniently adjusted in real time according to the direction of the sun and the incident angle of the light rays, so that the direct irradiation of the solar rays to the photovoltaic panel is ensured, and the solar radiation energy received by the photovoltaic panel in unit time is further remarkably increased.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation system manufacturing, in particular to a solar tracking device for photovoltaic power generation. Background technique [0002] Solar energy is the most widely distributed renewable energy on the earth. It is rich in resources, can be used for free, does not need transportation, and has no pollution to the environment. According to estimates, about 1.7×105TW of solar energy irradiates the earth's surface every year, and the potential value of actually available solar energy is about 600TW. If only 10% of solar energy is effectively utilized, there will be nearly 60TW of energy supply per year. [0003] However, in the promotion process of the existing photovoltaic power generation technology, due to the low photoelectric conversion efficiency, its market demand and production capacity are severely limited.

[0003] However, in the promotion process of the existing photovoltaic power generation technology, due to the low photoelectric conversion efficiency, its market demand and production capacity are severely limited

The reason is that in the prior art, the photovoltaic panels are all fixed design structures (that is, the pitch angle and relative rotation angle of the photovoltaic panels are both fixed values), so that the heating angle is fixed. However, with time, The incident angle of sunlight in different seasons is not the same, which leads to the phenomenon that solar radiation energy cannot be fully utilized.
