Description

Ship propeller

Technical Field

The utility model relates to the technical field of paddles, in particular to a paddle for a ship.

Background

The paddle is an important component of ship propulsion and plays a key role in the ship running process. The paddle is immersed in water by manpower, and then the force is applied to stroke, so that the ship advances. Conventional paddles typically consist of a shaft and a blade, the angle of which and the length of the shaft are typically fixed.

However, existing paddles may be inconvenient in some situations due to the fixability of the paddle shaft length. For example, different rowers may have large differences in height and arm length, and fixed length paddles may not be suitable for use by all. The use of a paddle of unsuitable length may cause discomfort to the rower's posture, and prolonged use may cause muscle fatigue and joint wear. In addition, the conventional paddle cannot adjust the blade angle according to different water flow and ship speed conditions, and may not realize the optimal propulsion effect. For example, in a turbulent river, failure to adjust blade angle may result in poor handling and stability, affecting propulsion efficiency. For this purpose, we propose a paddle for a ship.
