Problems solved by technology

[0002] Ancient ships used wood pulp to push water. Ships have been using propeller propellers for more than 200 years. This kind of propeller can obtain greater power and faster speed, and is suitable for large and small ships, but it consumes a lot of power and is not suitable for slow
[0003] In recent years, many disciplines have applied bionics to practice, and achieved many unexpected outstanding results, but so far no one has applied the life science of fish to propel water with its fins to the propulsion of ships

Abstract

A fin plate type propeller for ship is composed of at least one group of left and right fin plates and a reciprocating mechanism. Said fin plate are vertically hinged to a vertical axle. The top ends of both vertical axles are linked to a push-pull executing part of said reciprocating mechanism and the moving direction of said executing part is same as that of ship advancing. A transverse limit rod is arranged in the front of said fin plate and a locating block is arranged on the hinge of each fin plate. Its advantages are high efficiency and high speed.

Description

technical field [0001] The invention relates to a marine propeller, in particular to a fin plate opening and closing type marine propeller. Background technique [0002] Ancient ships used wood pulp to push water. Ships have been using propeller propellers for more than 200 years. This propeller can obtain greater power and faster speed, and is suitable for large and small ships, but it consumes a lot of power and is Not suitable for slow speed. [0003] In recent years, many disciplines have applied bionics to practice, and achieved many unexpected outstanding effects, but so far no one has applied the life science of fish to propel water with its fins to the propulsion of ships. Contents of the invention [0004] The purpose of the present invention is to fill in the vacancies and provide a flipper-type marine propeller, which can reduce energy consumption and improve propulsion efficiency. It is suitable for both fast driving and slow driving. It can be used in a singl...
