The invention discloses an off-grid photovoltaic power generation system based on flywheel clean battery energy storage. A cleaning model and a charging / discharging equivalent model circuit under a d-q shaft system are established; a control strategy in the flywheel battery charging / discharging process is analyzed and determined, a photovoltaic system and a flywheel battery are combined, a combined system is divided into four working models according to the supply-demand relation between the output power of the photovoltaic system and the power required by a load, and a control method of a combined controller is formulated. And analyzing and optimizing the operation state of the system under each working model and the energy storage and release effects of the flywheel battery. The combined system can stably operate under each working model and among the working models; the charging / discharging efficiency and the discharging depth are relatively high, and a quick response can be made to the difference value change of the output and the load power of the photovoltaic system; and energy is stored when the output of the photovoltaic system is residual, and energy is released to make up for the demand when the output of the photovoltaic system is insufficient, so that the electric energy quality is effectively improved, and the resource waste is reduced.

This invention relates to a self-leveling rotary transport device and method for docking and transferring multiple AUVs, belonging to the field of underwater robot equipment. It includes a docking module, a vertical transport module, and a rotary transport module. The docking module includes a rotary platform with a guide frame, and a first clamping device is provided on the top surface of the rotary platform. A vertical transport module is installed on one side of the docking module. The vertical transport module includes a liftable transport platform, and a locking device and a second clamping device are provided on the transport platform. The rotary transport module is installed below the docking module. The rotary transport module includes multi-branch shafts and horizontal plates installed on each set of branch shafts. An AUV charging and information interaction device and a third clamping device are arranged on the horizontal plates. This device increases the number of AUVs that can be docked and transferred, and can maintain the horizontal position of the AUVs during transfer, preparing them for subsequent actions such as AUV unloading. This invention also uses a separate rotary drive for the docking part to reduce the rotational resistance of the mechanism in seawater.
