This invention discloses a transverse flux linear-rotary switched reluctance generator with an overall axisymmetric decoupled drive structure. The stator module is composed of upper, middle, and lower stators layered axially.

This invention discloses a device and control method for cleaning floating debris in water. The invention employs a hybrid power generation method combining solar and wave energy to maintain sufficient power for better cleaning of floating debris. Furthermore, by analyzing the solar panel's power generation efficiency and surrounding environmental data, the invention raises and lowers the solar panel to an appropriate height. Because the front end of the telescopic rocker arm is connected to a protective cover containing the built-in solar panel via a self-resetting rotating joint, the solar panel can be retracted to the periphery of the floating debris under special conditions such as strong winds, flooding, or high tides. The protective cover, submerged in water, experiences buoyancy, allowing it to rotate and further flatten. This increases buoyancy while reducing the area exposed to wind and waves, thus reducing the thrust experienced by waves of the same size hitting the device, thereby reducing the risk of capsizing and minimizing the instantaneous load of large waves on the protective cover, effectively preventing damage to the device under special conditions.
