The photovoltaic agricultural mode that the photovoltaic module is installed at the upper part to generate electricity and the lower part to carry out agricultural production greatly improves the utilization rate of sunlight resources and land resources. However, the use of conventional stationary photovoltaic supports on agricultural lands has the following drawbacks:
1. the traditional fixed photovoltaic bracket needs to be buried in a large amount in the farmland, so that the overall installation cost and the construction difficulty are greatly increased; some farmlands (such as fruit trees and tea trees) do not allow the excavator to perform an operation (the excavator can destroy a large number of trees when the excavator is started), and only manual excavation and burying can be performed, so that the cost is higher and the efficiency is lower; the traditional fixed photovoltaic brackets are buried in a large amount in farmland with complex terrains (such as ravines and hills), which is more difficult;
2. some farmlands need to be operated by using agricultural machinery, and farmlands with a large number of traditional fixed photovoltaic brackets are buried, so that the operation space of the agricultural machinery can be greatly compressed, and the operation effect of the agricultural machinery is affected.
