A half-rotating flat-plate ship propeller

Abstract

The invention relates to a half-rotating flat plate ship propeller, and belongs to the technical field of ships. The half-rotating flat plate ship propeller comprises a main shaft, a rotary plate, an annular flat plate blade, a draw bar, a positioning bar, a shell, a filter screen and an energy storage mechanism. The depth-width ratio of the annular flat plate blade ranges from 2 to 3, the interior of the annular flat plate blade is of a honeycomb-shaped structure, the positioning bar is vertically arranged on a base plate of the shell, and the annular flat plate blade is installed on the positioning bar in a sleeving mode; a guide rail, a sliding block, a long spring, a short spring and a spring supporting bar are installed in a long-strip-shaped hole formed in the rotary plate, and the two sides of the sliding block are matched with the guide rail; the upper end of the draw bar is fixedly installed on the bottom face of the sliding block, and the lower section of the draw bar is inserted into the annular flat plate blade; the main shaft is installed in the center of the rotary plate,, the main shaft is vertically arranged on the upper portion of the rotary plate, and a bearing is installed on a support. The rotary plate rotates the draw rod to drive the annular flat plate blade to do half-circular movement in the shell, the movement effect and mirror surface effect similar to urgent spreading and sumo wrestling of insects can be produced, large pushing force is produced, and the efficiency is higher.

Description

technical field [0001] A semi-rotating flat plate ship propeller belongs to the technical field of ships, in particular 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 the traditional ship propulsion technology, and to invent a semi-rotary flat ship propeller with higher efficiency....

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
