Problems solved by technology

[0003] The sun tracking system is installed outdoors. Under the influence of wind load, the slewing support device will cause the whole sun tracker to vibrate back and forth due to the existence of gaps, which will cause the contact surfaces of the worm gear and worm to collide with each other, and "pitting" phenomenon will easily occur. Accelerate the damage of the equipment, and the service life of the sun tracking equipment is generally required to be more than 20 years. A big challenge in the field of tracker design

Abstract

An adaptive rotary device for solar tracking and a working method thereof belong to the field of solar trackers. The adaptive rotary device is arranged on a bracket of a solar battery pack (1) and comprises an azimuth angle rotation support (5) and / or an elevation angle rotation support (6). The orientation angle rotation support (5) and / or the height angle rotation support (6) comprise(s) a turntable shell (5a). A worm wheel (5f) is arranged in the turntable shell (5a). At least two worms (5d, 5e) are arranged around the worm wheel (5f). The plurality of worms (5d,5e) simultaneously keep engaging with the worm wheel (5f) and seamlessly and jointly drive the worm wheel (5f) to rotate at different time phase sequences and different rotation speeds in the same tendency. The device can perform seamlessly driving and tracking for a long time and automatically compensate gaps formed by abrasion.

Description

technical field [0001] The invention relates to a sun tracking system, in particular to an adaptive slewing device used in the sun tracking system. Background technique [0002] The sun tracking system is a power device that keeps the solar panel facing the sun at all times, so that the light of the sun can illuminate the solar panel vertically at any time, which can significantly improve the power generation efficiency of solar photovoltaic modules. On the sun tracking system, a slewing support device is provided for driving the sun tracking system to track the sun. The currently used slewing support device generally adopts the structure of external tooth type single row four-point contact ball type slewing bearing and worm. , and also the height angle is driven in this way. Because of the manufacturing and assembly method of the rotary support, there will always be a certain gap between the worm gear and the worm. The current better rotary support device can only The gap...
