Abstract

The invention discloses a column type sun tracking system horizontal rotation drive unit, characterized by comprising an internal support column which is sleeved by an external support cylinder coaxial with the internal support column; the upper portions of the internal support column and the external support cylinder are provided with a supporting part; the lower part of the external support cylinder is provided with a driving part, and a lower support frame. The invention also discloses a design method of the horizontal rotation drive unit. According to the invention, the supporting part, the driving part and the lower support frame are separated; the supporting part employs a thrust bearing; the driving part employs a ring and gear structure independent from the thrust bearing, thereby avoiding mechanical rotation torque waste, and effectively reducing manufacture costs; in addition, the damage of each part does not influence others; besides, the column type sun tracking system horizontal rotation drive unit employs a double gear anti-backlash control structure, and has high accuracy.

Description

technical field [0001] The invention belongs to the technical field of sun position tracking systems, and in particular relates to a horizontal rotation driving device of a column type sun tracking system, and also relates to a design method of the device. Background technique [0002] The single-column solar tracking system is widely used in the fields of solar photovoltaic power generation and solar thermal power generation. [0003] In the field of solar photovoltaic power generation: [0004] The installation of battery panels in solar photovoltaic power generation systems is divided into fixed type and tracking type. The photovoltaic tracking system can reduce the angle between the normal line of the battery panel and the incident light of the sun, thereby improving the power generation efficiency. The tracking type is divided into single-axis and dual-axis tracking systems. The so-called column tracking system means that a horizontal rotation driving device is set on...
