[0002] The continuous increase in the capacity of photovoltaic power stations has led to a continuous reduction in advantageous resources for power station construction. The "photovoltaic power station" construction model in animal husbandry areas can be used as a new development route. Some areas with developed animal husbandry provide sufficient land space for the construction of solar photovoltaic power stations. Compared with desert Gobi areas, mountainous areas have relatively complex terrain, and there is a high demand for photovoltaic system deceleration devices. Referring to the Chinese patent, the application number is "201520138663.X" "Self-protection solar tracker with slewing deceleration device", which solves the problem of being unable to effectively limit a specific rotation angle range and the loss caused by slewing damage, but there are still defects such as difficulty in coordinating spacing arrangements with natural conditions, uncontrollable investment costs, and high investment in later operation and maintenance. In response to this, we proposed a multifunctional flexible tracking slewing reducer to solve the above problems. Utility Model Content
