Problems solved by technology

The Chinese patent application number 200310106145.1 proposes a good bionic flat-panel ship propeller, which utilizes the Weis-Fogh effect, but has three deficiencies. One is that its blades rotate while revolving, and the structure is more complicated; The second is that it adopts a "half-turn mechanism", which can only produce "sumo and tension" movement on one side to realize the Weis-Fogh effect, and the efficiency is low; The larger the front water area, the greater the resistance to the ship

example 1

[0019] Example 1, using a propeller of the present invention, the device is installed in the middle position below the stern of the hull, the outer fixed plate is installed below the hull, and the inner fixed plate is installed above the outer fixed plate near the hull and fixed on the hull. The two baffles are parallel to the longitudinal symmetrical plane of the ship, and the inner fixed plate is parallel to the horizontal plane. Viewed from the right side of the hull, the ship moves forward when the crank is turned clockwise, otherwise the ship moves backward.

[0020] Example 2, using two propellers of the present invention, they are symmetrically arranged on both sides of the lower part of the hull with the longitudinal symmetry plane of the ship as the symmetry plane. On the longitudinal symmetrical plane of the ship, the four baffles are all parallel to the horizontal plane and fixed on the hull, and the upper baffle is installed close to the lower part of the hull.

Abstract

The invention relates to a plate paddle square tube propeller for vessels, which is composed of a crank, a connecting bar, a connecting bar guide, plate paddles, an inner side fixing plate, an outer side fixing plate and two baffle plates. Motor drive is transmitted to the crank by a reducer casing, one end of the connecting bar does circular motion under traction of the crank, the other end does closed curvilinear motion similar to the profile of 'human ears', the middle of the connecting bar slides reciprocally in the connecting bar guide, the plate paddles do motion constantly and reciprocally 'flap and unfolding' similar to an insect in a square tube surrounded by the inner side fixing plate, the outer side fixing plate and two baffle plates under drive of the connecting bar, thereby Weis-Fogh effect is produced to propel a vessel to navigate. The plate paddle square tube propeller for vessels has simple structure, high efficiency and safety.

Description

technical field [0001] The invention relates to a square-tube thruster with flat blades for ships, which belongs to the technical field of ship machinery. Background technique [0002] At present, ship propulsion mainly adopts mechanical propellers and human blades. The traditional propeller has several disadvantages. First, it produces rotating turbulent flow, with large wake and low efficiency; Manufacturing is difficult. Human paddles have almost zero automation and low power. The Chinese patent application number 200310106145.1 proposes a good bionic flat-panel ship propeller, which utilizes the Weis-Fogh effect, but has three deficiencies. One is that its blades rotate while revolving, and the structure is more complicated; The second is that it adopts a "half-turn mechanism", which can only produce "sumo and tension" movement on one side to realize the Weis-Fogh effect, and the efficiency is low; The larger the front water area, the greater the resistance to the sh...
