Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] figure 1 A schematic structural diagram of a transmission control mechanism for a photovoltaic tracker provided by an embodiment of the present invention. Photovoltaic trackers here refer to trackers used in solar photovoltaic power generation systems. Since the cost of the photovoltaic tracker is very low compared to the total cost of the photovoltaic power generation system, it will not increase the cost of the photovoltaic power generation system, but it can be adjusted with the sun's azimuth angle, which can significantly increase the power generation. Trackers can be divided into flat-panel photovoltaic panel trackers, lens-type and reflective concentrated photovoltaic trackers according to their uses, and can be divided into various types according to the number and direction of the rotation axis. The purpose of all these trackers is to collect...

Abstract

The invention discloses a transmission control mechanism for a photovoltaic tracker, the photovoltaic tracker and a transmission control method. According to the transmission control mechanism, two motors are simultaneously connected to a speed reducer, and only one motor is allowed to be in working state; a central control unit is used for monitoring the working states of the two motors; and when failure is monitored in work of a first motor, a first switch and a second switch for controlling the first motor and a second motor are switched so as to turn off the first motor and turn on the second motor. Extremely tiny cost of the entire system is increased, the second motor is used as a standby motor, and the transmission control mechanism is quickly switched to the standby motor to work when the first motor used as the working motor fails, so that the long-term reliable operation of the system is guaranteed, the reliability of the photovoltaic tracker is improved, the power generation loss is avoided, and the maintenance cost and the loss caused by stop of power generation due to maintenance are reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic trackers, in particular to a transmission control mechanism for a photovoltaic tracker, a photovoltaic tracker and a transmission control method. Background technique [0002] As a green energy, solar energy has the characteristics of great potential and sustainable utilization, and has become the focus of competing development in various countries, but the high cost of photovoltaic power generation restricts its rapid development. One of the solutions is to increase the power generation capacity of the unit power generation system, and use the photovoltaic tracker to make the light-receiving surface of the flat-panel photovoltaic module face the sun at all times. Under the same irradiation conditions, the automatic angle adjustment mode can absorb more solar radiation energy than fixed-installed photovoltaic modules, thereby improving the efficiency of photovoltaic power generation. [0003] Existing...
