Document Type and Number:
WIPO Patent Application WO/2023/103451
Kind Code:
A1
Abstract:
A pre-propeller energy-saving structure and a pre-propeller pre-rotation energy-saving apparatus. The energy-saving structure comprises guide vanes (100) and bent portions (200); one end of each guide vane (100) is connected to a ship body (300); each bent portion (200) is arranged at the root of the guide vane (100), and the bent portion (200) is connected to the guide vane (100); and the bent portion (200) and the guide vane (100) can form a flow guide surface capable of guiding flow towards the top end of the guide vane (100). According to the energy-saving structure and the energy-saving apparatus, a liquid at the root of the guide vane can be guided to the top end of the guide vane, a wake field at the tail of a ship is fully utilized, and the energy-saving effect is improved.
