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

The invention discloses an adaptive rotation device for sun tracking and belongs to the field of sun trackers. The adaptive rotation device for sun tracking is arranged on a bracket of a solar battery pack and comprises an orientation angle rotation support and / or a height angle rotation support, wherein the orientation angle rotation support and / or the height angle rotation support comprises a turntable shell; a worm wheel is arranged in the turntable shell; at least two worms are arranged around the worm wheel; and the plurality of worms simultaneously keep engaged with the worm wheel and seamlessly and jointly drive the worm wheel to rotate at different time phase sequences and different rotation speeds in the same tendency. The adaptive rotation device for a sun tracking system is simple in structure, low in cost and long in service life, is convenient to use and can seamlessly drive the sun tracking system to perform 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 on the sun tracking system. Background technique [0002] The sun tracking system is a power device that keeps the solar panel facing the sun at any time, allowing the sunlight to illuminate the solar panel vertically at any time, which can significantly improve the power generation efficiency of the solar photovoltaic module. On the sun tracking system, a slewing support device is provided to drive the sun tracking system to track the sun. The currently used slewing support device generally adopts the structure of the external tooth single-row four-point contact ball slewing bearing and the worm. , there is also a height angle that is driven by this method. Due to the manufacturing and assembly method of this rotary support turntable, there will always be a certain gap between the worm wheel and the worm. At present, the better rotary support device can o...
