Abstract

The invention discloses a synchronizing propeller device. The synchronizing propeller device mainly comprises paddle blades (3) and rotating wheels, wherein an upper rotating shaft (4) of the paddle blades (3) is connected with an upper rotating wheel by being inserted into an upper shaft seat (6), a lower rotating shaft (5) of the paddle blades (3) is connected with a lower rotating wheel by being inserted into a lower shaft seat (7), the paddle blades (3) are perpendicular or parallel to a rotating shaft (8) of the rotating wheels, the a rotating shaft (8) is directly connected with an output shaft of a power device, and each paddle blade (3) is symmetrically mounted. In a rotation process, the paddle blades (3) always perpendicularly enter into water. The device is widely used, and can be used in the aspects of ship propellers, water turbines, steam turbines, hydroelectric generation or tidal power generation and the like, the ship with the propeller provided by the invention can sail in shoal water, and also can sail in a water plant zone, a trash floating zone and a subaquatic sludge zone, so that the ship with the propeller has wide sailing are; and the synchronizing propeller device is low in manufacturing cost and simple and convenient to maintain.

Description

technical field [0001] The invention relates to the field of thrusters, in particular to a synchronous thruster device. Background technique [0002] The most advanced paddle wheel is a paddle wheel with variable web entry angle invented by the British. This "paddle wheel" propeller is a propeller commonly used in ships in the early days, and is suitable for ships navigating on inland rivers and lakes. The entire propeller is in the shape of a wheel, and the wheel shaft is placed horizontally along the width of the ship and above the waterline of the ship. There are fins on the periphery of the wheel, but the structure of this invention is asymmetrical, and the rotation of each corresponding mass point during rotation The penetration is not equal, so the speed is very low, resulting in low efficiency and large diameter, and the draft of the web cannot exceed half the radius of the paddle wheel; otherwise, when the paddle wheel rotates, the lifting force of the ship will be i...
