A new type of marine propulsion device imitating fish tail

Abstract

The invention provides novel fishtail imitation ship propelling devices which are mainly applied to the field of ships. Each novel fishtail imitation ship propelling device comprises a motor for providing a power effect, a steering engine, a fishtail imitation hydrofoil, a belt, a connecting rod, belt wheels, a steering engine base, a supporting base and pins. According to the novel fishtail imitation ship propelling devices, on the one hand, the motors are used for providing power and drive the steering engines to do reciprocating movement between the belt wheels through the belts, on the other hand, the steering engines control the movement attack angles of the fishtail imitation hydrofoils through the connecting rods, thus, the fishtail imitation hydrofoils can produce a fishtail swing effect, and thrust can be produced; and in addition, in order to relieve ship body vibration caused by the hydrofoils, the two fishtail imitation propelling devices are symmetrically installed in the ship width direction, and vibration produced by the hydrofoils on a ship body can be offset with by each other.

Description

technical field [0001] The invention relates to a propulsion device, in particular to a novel fishtail-like marine propulsion device, which belongs to the field of ships. Background technique [0002] The study of bionic propulsion methods is an important aspect of the current research in the field of bionics. Simulating the excellent ability of organisms under specific conditions to create propulsion devices with specific advantages that have evolved over tens of millions of years is the key to the research of bionic propulsion methods. Target. [0003] At present, the bionic propulsion applied in the field of ships, taking the application number CN201510307414.3 as an example of a fishtail propulsion device suitable for small waterplane area catamarans, the design stability of the mechanism is poor, and it is prone to fatigue. Have not yet seen that there is a power unit that drives the steering gear to move by the motor to imitate the swing of the fish as the propulsion ...

Problems solved by technology

[0003] At present, the bionic propeller applied in the field of ships, taking the application number CN201510307414.3 as an example of a fishtail propulsion device suitable for small waterplane area catamarans, the design stability of the mechanism is poor, and it is prone to fatigue

I haven't seen a power device that uses the motor to drive the steering gear to imitate the swing of the fish as the propulsion of the ship.
