An auxiliary propulsion arrangement for an electrically powered watercraft
PendingCN122078603AAvoid high temperature wearavoid deformationRotary propellersPropulsion power plantsMarine propulsionPowered watercraft
This invention relates to the field of marine propulsion technology, specifically to an auxiliary propulsion structure for electric ships. The structure includes a ship hull, a propeller mounted on the bottom of the hull, and rotating rods fixedly connected to both sides of the hull. An auxiliary propeller is mounted on each rotating rod. Through an idling cooling mechanism, when the water inlet is above the water surface, causing the drive rod to drive the auxiliary propeller to idle, the idling cooling mechanism opens an emergency water path. This allows pre-stored cooling water from the tank to be precisely delivered via drip pipes to the junction of the drive rod and the bearing. This directional dripping forms a water film at the friction interface, providing immediate lubrication and drag reduction, as well as rapid heat absorption and cooling, preventing high-temperature wear, deformation, or sintering of components. Compared to traditional unprotected designs, this mechanism is fast-responding and highly targeted, minimizing damage to core components during idling and ensuring reliable operation of the auxiliary propeller in complex waters.
