Abstract

The invention discloses a solar tracking interconnected three-shaft double-column robot which comprises a driving mechanism, main columns, an assembly, a bracket, a double-shaft tracking mechanism and a vertical lifting mechanism. The main columns comprise a south main column (7) and a north main column (5). The vertical lifting mechanism comprises an electric transmission device (32), a main wire rope (27), a lifting wire rope (29), a fixed pulley set (28), a movable pulley set, a sliding sleeve, a wire rope adjusting device and a rope clamp. The main columns are fixed in the sliding sleeve and can vertically slide. The sliding sleeve is provided with a groove for penetration of the lifting wire rope. An electric transmission mechanism performs traction on the main wire rope for performing reciprocation. The main wire rope is provided with the rope clamp. One end of the lifting wire rope is fastened in the wire clamp, and the other end bypasses the fixed pulley set, the sliding sleeve and the movable pulley set at the bottom end of the main columns and is fixed in the wire rope adjusting device. The solar tracking interconnected three-shaft double-column robot has advantages of smooth electric power generating power and electric power generating capacity characteristic curves and low change rate. The solar tracking interconnected three-shaft double-column robot realizes a fact that sunlight always irradiates the panel of a photovoltaic photo-thermal assembly in an optimal time period.

[0002] Due to the rotation of the earth, compared with a solar photovoltaic power generation system at a fixed location, the sun rises and sets every day in the four seasons of the year, and the angle of the sun’s illumination changes all the time. For the sun, achieving the best power generation efficiency is a long-term need to face in the field of solar photovoltaic power generation technology. The solar tracking system is the key to the maximum utilization of solar photovoltaic light and heat. It is a mechanical and electronic control unit system that improves the photoelectric conversion efficiency. The solar panel faces the sun at any time, so that the sunlight irradiates the mechanical equipment of the solar photovoltaic thermal module vertically at any time, which can improve the photoelectric thermal efficiency of the solar photovoltaic thermal module. However, the solar trackers currently on the market still have the following problems: 1. Too many two-axis solar trackers are driven separately by two axes, which consumes a lot of electricity and costs a lot. The transmission devices such as motors, various sensors and electronic controls consume a lot and cannot be linked with each other; 2. Due to the large load of the entire transmission system , so that the weight and quantity of the overall steel structure and transmission mechanical equipment are large; 3. The single-axis solar tracker has no altitude tracking transmission device or azimuth tracking transmission device, and its tracking error is large, tracking accuracy is not high, and the power generation efficiency is low. (or photovoltaic photothermal comprehensive efficiency) is low. In addition, there is a more important point. The current solar power generation bases are basically arranged in arrays. All solar photovoltaic photothermal equipment are installed at the same height, and the daily The angle of sunlight in the morning, noon, and evening changes at any time. When the distance between the solar photovoltaic thermal equipment in the array is small and the density is high, there will be a photovoltaic thermal "blind area". Solar panels cause flare phenomenon, which not only reduces the efficiency of photovoltaic thermal power generation, but also reduces the service life of solar panels or even damages them due to long-term blind spots
