Embodiment Construction

[0015] As shown in the figure: a folding webbed marine propeller, mainly composed of connecting arm 1, water diversion bracket 2, web plate I3 and web plate II4, wherein one end of the connecting arm 1 is provided with a connecting thread, and the other end of the connecting arm 1 is provided with a connecting thread. One end is connected to the water distribution bracket 2.

[0016] The water diversion bracket 2 is a V-shaped groove structure composed of two water diversion plates 5 and two side plates 6, wherein the angle between the two water diversion plates 5 is 140-160°, and the two side plates 6 is correspondingly provided with the rotating shaft through hole 7.

[0017] The fins Ⅰ3 and Ⅱ4 are hinged together through the rotating shaft 8, which is similar to the traditional hinge structure. Both the webs Ⅰ3 and Ⅱ4 can rotate along the rotating shaft 8, and the side of the webs Ⅰ3 and Ⅱ4 are mutually matched. The concave-convex groove structure of the web plate I3 and t...

Abstract

The invention relates to a folded paddle type ship propeller. The propeller mainly consists of a connection arm, a water diversion bracket, a paddle board I and a paddle board II; one end of the connection arm is provided with a connection thread, and the other end of the connection arm is connected with the water diversion bracket; the water diversion bracket is in a V-shaped groove structure consisting of two water diversion boards and two lateral boards; rotating shaft through holes are correspondingly arranged on the two lateral boards; the paddle board I and the paddle board II are hinged through a rotating shaft; the both ends of the rotating shaft respectively extend out from the two rotating through holes of the two lateral boards; and a plug is sleeved at an extending part of the rotating shaft. The folded paddle type ship propeller provided by the invention is a ship propeller in a new structure; the paddle boards are continuously unfolded and closed, so as to provide power for aviation of a ship. The paddling motion of the paddle boards is slow, so that no high-speed periodic driving force is generated. Furthermore, compared with a spiral propeller, the folded paddle type ship propeller has smaller noise and better elusiveness.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a folding-fin type marine propeller. Background technique [0002] At present, the propulsion force generated by the rotation of the propeller is the driving force of most ships, which pushes the ship forward. When the propeller moves, the resistance of the water is very large, resulting in high operating intensity and low work efficiency, which directly affects the sailing speed of the ship and produces relatively large noise. Especially when it is assembled on a small cruise ship, the exhaust gas brought by this ship propeller And noise pollution will bring greater discomfort to tourists. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above technical problems, to provide a folding fin marine propeller, due to its slow paddling action, does not produce high-speed periodic driving force, and has less noise th...
