Problems solved by technology

[0005] The working efficiency of the paddles and blades is low, the noise is loud, the speed and direction are changed slowly, and the braking is slow. The fluid acting on the blades produces additional resistance, which is easy to harm creatures and be troubled by fibrous substances

Embodiment Construction

[0048] exist figure 1 , 2 , 3, the blade g only acts on the fluid on the y-axis, the negative half-axis of the z-axis, and the positive and negative half-axis of the x-axis to generate a reaction thrust. When the paddle shaft rotates clockwise, the paddle g is transferred clockwise, and the paddle g faces the straight pushing action fluid, and the reaction thrust is generated in the front, rear, up and down directions:

[0049] The blade g moves backward, and the base points 46 and 49 of the blade g coincide with the base points 13 and 18 of the trajectory of the endpoint of the blade g respectively; The base point 49 of the blade g is rotated 90 degrees with the base point 13 as the center of the circle, and coincides with the base point 1 of the blade g. base point 21 of the trajectory of the blade g; the blade g moves forward, and the base points 45 and 48 of the blade g coincide respectively with the base point 43 of the blade g and the base point 24 of the end point of...

Abstract

The wheel chain paddle is a kind of motorized thrust device, which is mainly composed of blades, paddle chains, paddle wheels, paddle shafts and paddle channels. The paddle action fluid produces the reaction force thrust. Wheel chain paddles are mainly used in the field of boats. They are symmetrically installed on the left and right sides of the hull. The asymmetric force of the left and right wheel chain paddles controls the movement direction of the hull, and the paddle shaft is perpendicular to the movement direction of the hull. Chain paddles eliminate the extra drag created by the blade action fluid.

Description

technical field [0001] The invention relates to a propulsion device for a boat and a boat-pushing device. [0002] technical background [0003] At present, the propulsion tools and propulsion devices of boats can be divided into three types: poles, oars, and sculls. The pole is a kind of punting tool made of bamboo poles or Chinese fir. The pole acts on the front and back of the solid to generate a reaction force and push the hull to move forward and backward. The pole and the hull are not fixed; the oar is a wooden dial with a narrow top and a wide bottom. The boat tool and the boat-turning device, the boat-turning tool and the hull are not fixed, the boat-turning device has a fixed fulcrum with the hull, and the fluid acts on the front and rear or left and right directions to generate a reaction force and push the hull to move forward and backward; the scull is a kind of wooden bionic fish The stern swing ship device, the left and right direction of the scull acts on the ...
