A single-axis tracking photovoltaic power generation structure

Abstract

The invention discloses a single-axis tracking photovoltaic power generation structure, which comprises solar photovoltaic assemblies and a fixed base, wherein the fixed base is used for mounting the solar photovoltaic assemblies; the fixed base is connected to the top parts of a plurality of upright posts through hinges; the plurality of upright posts are linearly arranged; a diagonal bar, an oscillating bar and an adjusting screw are arranged at the positions of the upper part of at least one upright post; the upper ends of the diagonal bars are hinged with the fixed base; the lower ends of the diagonal bars are hinged with and supported on bearings of the upright posts; a sliding sleeve sleeves each diagonal bar; an adjusting nut sleeves each adjusting screw; one end of each oscillating bar is hinged with the corresponding sliding sleeve; and the other end of each oscillating bar is hinged with the corresponding adjusting nut; and two ends of each adjusting screw are fixedly butted with a feed rod. An angle adjusting mechanism combining a connecting rod mechanism and a nut-screw pair is adopted for adjusting the elevation angles of the photovoltaic assemblies, so that the adjusting mechanism is simple in structure, reasonable in design, low in fault rate, reliable in adjusting action and convenient to manufacture and use, and also reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a single-axis tracking photovoltaic power generation structure, which belongs to the technical field of solar energy utilization. Background technique [0002] Solar energy is a clean and non-polluting renewable energy. Fully exploiting and utilizing solar energy can not only save conventional energy that is increasingly depleted, but also reduce pollution and protect the environment. [0003] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. In order to obtain the best power output of the photovoltaic power generation device, the solar cell modules must be installed in a certain orientation in combination with the natural environmental conditions such as the construction site, the month and the season, so that the solar cell modules can face or basically face the sun, so that Ensure that solar photovoltaic p...

Problems solved by technology

Although the fixed installation method has the advantages of simple structure and convenient installation and fixing, because it cannot be tracked and adjusted according to the azimuth of the sun, the power generation efficiency is low, and it is difficult to give full play to the power generation efficiency of the photovoltaic power station.

The dual-axis tracking installation method in the adjustment tracking type can track the azimuth of the sun. Although it has the highest power generation efficiency, the adjustment structure is complicated, the failure rate is high, and more driving power is required
