Solar-tracking interconnecting dual-column robot

Abstract

The invention discloses a solar-tracking interconnecting dual-column robot comprising a driving mechanism, a south main column (7), a north main column (5), a support spindle (12), a light absorbing bracket (18), a bevel gear transmission device (25), a dynamic shifting transmission mechanism (8), and a reversible speed-adjusting geneva wheel mechanism (9). A drive unit and an intermediate shaft (6) are connected with the bevel gear transmission device and a lower chain wheel (24); the lower chain wheel and an upper chain wheel (20) on the support spindle are wound with circular-ring chains (23); the bevel gear transmission device is connected with the reversible speed-adjusting geneva wheel mechanism; and the dynamic shifting transmission mechanism is arranged between the lower chain wheel and the upper chain wheel. The dynamic shifting transmission mechanism includes a rack (802). And the reversible speed-adjusting geneva wheel mechanism consists of a bevel gear shaft seat (901) and a control panel (906). With a spring balancing device, the force and torque changes caused by tracking the sun by a main support can be balanced; the motor power is reduced; and the equipment light-weight effect is realized.

[0002] Due to the rotation of the earth, compared with a solar photovoltaic thermal power generation system at a fixed location, the four seasons of the year are spring, summer, autumn and winter, and the sun rises and sunsets every day. The module can face the sun at all times, and the best power generation efficiency is the long-term need to face in the field of solar photovoltaic and thermal power generation technology. The solar tracking system is to optimize the use of sunlight in the process of photovoltaic and solar thermal power generation to improve the photoelectric conversion. High-efficiency mechanical and electronic control unit systems, keeping the power plant facing the sun when solar photovoltaic light and heat can significantly improve the photoelectric efficiency of solar photovoltaic modules, but the solar trackers currently on the market still have the following problems: 1. Dual-axis solar energy Too many tracking machines are driven separately by two shafts, which consume a lot of electricity and cost a lot, and the rotating devices such as motors, various sensors and electronic controls consume a lot of energy and cannot be linked with each other; 2. Due to the large load of the entire transmission system, the overall steel structure 3. The single-axis solar tracker has no elevation angle tracking transmission device, which has large tracking error, low tracking accuracy, and low power generation efficiency (or photovoltaic photothermal comprehensive efficiency)
