Semi-rotating panel ship propeller provided with energy storage device

Abstract

The invention provides a semi-rotating panel ship propeller provided with an energy storage device and belongs to the technical field of ships. The semi-rotating panel ship propeller comprises a main shaft, a rotating disc, an annular panel blade, a traction rod, a positioning rod, a shell and an energy storage device. The positioning rod is vertically arranged on a bottom plate, and the annular panel blade is arranged on the positioning rod in a sleeving mode; the rotating disc is horizontally arranged above the panel blade, and the lower segment of the traction rod is inserted into the annular panel blade. The gap between two panels of the annular panel blade is slightly larger than the sum of outer diameters of the traction rod and the positioning rod, and the main shaft is vertically mounted at the center of the rotating disc. In the linear advancing process of the annular panel blade, a spring mechanism is utilized to store certain energy, after the annular panel blade advances to the front most position and begins to rotate around the positioning rod, and the stored energy is released rapidly, so that the annular panel blade is opened more rapidly between the front and a left side board of the shell. The panel blade conducts half-cycle movement in the shell, the movement effects of 'rapid unfolding' and 'sumo' similar to insects and the mirror surface effect can be generated, and thrust generation efficiency is high.

Description

technical field [0001] The utility model relates to a semi-rotary flat plate ship propeller with an energy storage device, which belongs to the technical field of ships, and in particular relates to a ship propeller. Background technique [0002] Most traditional ship propellers use propellers. Although they are easy to drive, their efficiency is low. The manufacturing process of the blades is complicated, and wakes will be generated when they are used. After the water enters and before the water exits, the water resistance is large and the thrust generated is very small, the energy loss is large, the efficiency is low, and the noise is large. Authorized notification number is the patent of CN100360378C, discloses a kind of bionic flat ship propeller, although efficiency is higher, structure is more complicated. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of traditional ship propulsion technology,...

AI Technical Summary

Problems solved by technology

[0002] Most traditional ship propellers use propellers. Although the drive is convenient, the efficiency is low, the manufacturing process of the blades is complicated, and wakes will be generated when used; the traditional paddle wheel propellers have water splashing when used, and the water splashes are large, and the blades are stiff. After the water enters and before the water exits, the water resistance is large and the thrust generated is small, the energy loss is large, the efficiency is low, and the noise is large

The patent with authorized notification number CN100360378C discloses a bionic flat ship propeller, although the efficiency is high, but the structure is relatively complicated
