[0026] When in use, the cylinder 204 is started by an external power supply, and the output end of the cylinder 204 extends or contracts. When the output end of the cylinder 204 extends, the gear plate 203 is driven to move rightward, and the gear 202 and the gear plate 203 drive the adjustment plate 201 and the stern plate body 40 to rotate counterclockwise; when the output end of the cylinder 204 contracts, the gear plate 203 is driven to move leftward, and the gear 202 and the gear plate 203 drive the adjustment plate 201 and the stern plate body 40 to rotate clockwise, thereby achieving the effect of multi-angle adjustment of the stern plate body 40. And the angle of the stern plate body 40 is adjusted by the cylinder 204 as a driving member, which has the characteristics of large adjustment range, high precision, fast response speed, and can withstand large loads.

[0027] And by adjusting the angle of the stern flap, firstly, the water flow distribution around the hull can be changed, thereby optimizing the hydrodynamic characteristics of the hull. This optimization helps to reduce resistance during navigation, thereby reducing fuel consumption and improving fuel efficiency. Secondly, the adjustable angle stern flap can assist the ship in turning more easily. When the course needs to be changed quickly, adjusting the angle of the stern flap can generate additional force and torque, helping the ship respond to steering commands more quickly.

[0028] Furthermore, built-in grooves 205 are provided on the top and right sides of the regulating box 11, and flexible steel sheets 206 are slidably connected inside the built-in grooves 205, and the inner sides of the two flexible steel sheets 206 are fixedly connected to the regulating plate 201.
