Description

Mixed type wheel oar

Technical Field

The utility model belongs to the technical field of wheel paddles, and particularly relates to a hybrid wheel paddle.

Background

The wheel paddle, also called paddle wheel, is a propeller of ship, it installs the paddle board on the circumference of wheel body, drives the paddle board through rotating the wheel body and dials water to do work.

The main disadvantages of the wheel paddles are: the structure is heavy, the efficiency is low, especially when encountering stormy waves, the paddle boards which are originally supposed to be under the water surface and dial water to do work can be partially or even completely exposed out of the water surface, so that the ship cannot stably navigate, and the ship has application on ships which are used in water areas without large surges and have shallow draft and low navigational speed.

The wheel paddles can be divided into fixed wheel paddles and movable wheel paddles according to paddle board forms: the paddle board of the fixed wheel paddle moves in a fixed mode, namely, when the wheel body drives the paddle board to revolve around the axis of the wheel body, the paddle board is fixed relative to the wheel body, so that the diameter of the fixed wheel paddle is often quite large for improving efficiency, and the water inlet depth is not more than 1/2 of the radius (see 1-1 in figure 1); the paddle board of the movable wheel paddle moves in a movable mode, namely, when the wheel body drives the paddle board to revolve around the axis of the wheel body, the paddle board moves relative to the wheel body, in particular, autorotation occurs, the movable wheel paddle is provided with a control mechanism, so that the paddle board can generate autorotation and control the detail of autorotation, and the paddle board of the movable wheel paddle can dial water in a more reasonable mode relative to the fixed wheel paddle (see 1-2 in fig. 1).

The wheel paddle combines the characteristics of the fixed wheel paddle and the movable wheel paddle, and when the wheel paddle rotates, namely, when the wheel body drives the paddle board to revolve around the axis of the wheel body, the paddle board moves in an alternating mode of a fixed mode and a movable mode on a 360-degree revolution interval, so that the paddle board can dial water at a better angle.

The existing wheel paddles are not used in water in the upper half part, because the movement direction of the paddle board of the upper half part is opposite to that of the lower half part, the paddle board forms are not optimized, and the generated harmful work is very large; the wheel paddle can greatly reduce the harmful work generated when the paddle board positioned at the upper half part dials water, so that the upper half part of the wheel paddle can be used in water.
