An asymmetric rotating blade propelled boat

Abstract

The invention discloses an asymmetrical rotating paddle propulsion boat and belongs to the technical field of boats. The boat comprises a boat body, a left propeller, a right propeller and an operation system. The left propeller and the right propeller are the same in structures, parameters and operation principles and are installed on left and right sides of the boat body symmetrically; the right propeller comprises an engine, a reducer, a spindle, a rotating disc, a guide cover, a central half gear and two, three or four rotating paddle devices; the central half gear is fixed below the deck of the boat body; the spindle is arranged vertically, and the lower end is fixedly connected to a rotary arm; each rotating paddle device comprises a proximal gear, a distal gear and a blade; the engagement ratio of the proximal gear and the distal gear is of 1:1, and the engagement ratio of the proximal gear and the central half gear is of 1:1; the blade is maintained in a transverse vertical state and pulls backwardly, is perpendicular to the rotary arm and returns forwardly. During operation, obvious wave of the boat is avoided, and the boat is high in efficiency and flexible and can be applied to water transportation and sports and recreation activities.

Description

technical field [0001] The utility model relates to an asymmetrically rotating paddle propelled boat, which belongs to the technical field of ships, and in particular relates to a flat rowing paddle boat. Background technique [0002] Traditional ship propulsion devices mostly use propellers, although the drive is convenient, but the efficiency is low, the manufacturing process of the blades is complicated, and wakes will be generated when used; A half-turn mechanism flat-panel ship propulsion device with high efficiency, but only one position of the blade is perpendicular to the forward direction when paddling backwards, and the other positions are not at 90° to the forward direction. The generated component force is not helpful to the forward movement, and part of the energy is lost, so the efficiency is not too high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of traditional small boats, and in...
