Fair water fin with adjusting function used for ship

Abstract

The invention discloses a fair water fin with an adjusting function used for a ship. The fin comprises a ship body, a rotary shaft, a fair water fin body and a propeller shaft. A motor bin is arranged in a position, close to the fair water fin, of the ship body. The interior of the motor bin is fixed with a stepping motor. The stepping motor is vertically and downwardly provided with an output shaft. The output shaft is connected with a speed changer. The rotary shaft penetrates through the ship body and extends into the motor bin so as to be rotatably connected with the speed changer. The bottom end surface of the fair water fin is fixedly welded with a bearing seat. Two side surfaces of the fair water fin are symmetrically welded with a first fair water board and a second fair water board. The first fair water board and the second fair water board are distributed in the form of longitudinal symmetry. Water guide holes are uniformly arranged in the fair water fin. The propeller shaft penetrates through the ship body and is rotatably connected to a ship power mechanism in the ship body. The position where the propeller shaft penetrates through the ship body is subjected to sealing and water-proof treatment. One end, away from the ship power mechanism, of the propeller shaft is rotatably connected to a propeller hub. The surface of the propeller hub is welded with spiral propeller blades. The front end surface of the propeller hub is provided with a propeller cap. The fair water direction of the fair water fin can be adjusted within a certain range.

Description

technical field [0001] The invention relates to the technical field of ship accessories, in particular to an adjustable guide fin for ships. Background technique [0002] Ships play an important role in the freight market because of their large load capacity and low cost. Especially when the requirements for greening ship operations are proposed, various energy-saving measures have been valued by shipowners, which is the need for sustainable development of the country. The shipping industry and even the national energy strategy are of great significance. [0003] The general driving methods of ships include propeller and water jet propulsion. In the case of propeller drive, guide fins, guide covers and guide pipes installed on the propeller form an energy-saving mechanism. The diversion effect of the structure diverts the seawater at the propeller so that the water flow can touch the propeller smoothly, which can improve the working efficiency of the propeller. The propuls...
