Optical lens focusing system rotation and deflection mechanism
The utility model discloses an optical lens focusing system rotation and deflection mechanism, particularly relates to a focusing system rotation and deflection mechanism applied to the high pixel camera optical lens, which comprises a base, wherein the base is provided with a drive unit, a swing arm is arranged in the base, one end of the swing arm is fixedly provided with a focusing lens, and the other end of the swing arm is hinged with a guide rod, and the base is also provided with a driven unit which can drive the swing arm to rotate to be hidden after the swing arm is driven by the drive unit to move up and down along the guide rod and then move downward in place. The utility model is applicable to the fields of the digital camera or the cell phone and the like.
The paper proposes a mathematical model to optimize wind power turbine maintenance by minimizing the total costs with preventive maintenance, corrective maintenance and costs due to energy losses. Objective function is an economic function and is represented by the total costs associated with actions of preventive maintenance, corrective maintenance and production losses due to interruption of equipment operation during maintenance activities. Furthermore, a study case is presented to show the implementation of the proposed mathematical model.
