A kind of propulsion device of semi-rotating annular flat blade ship with spring

Abstract

The invention relates to a half-turn annular flat vane ship propulsion device with a spring, and belongs to the technical field of ships. The half-turn annular flat vane ship propulsion device comprises a main shaft, a rotary table, an annular flat vane, a traction rod, a locating rod, a casing and a filter net, wherein the locating rod is vertically mounted near a left side plate on a bottom plate of the casing; the annular flat vane is mounted on the locating rod in a sleeving manner; the rotary table is horizontally arranged above the flat vane, and a guide rail, a sliding block and a long spring are mounted on the rotary table; the upper end of the traction rod is mounted on the sliding block, and the lower segment of the traction rod is inserted into the annular flat vane; the outer diameter of the traction rod and the outer diameter of the locating rod are slightly smaller than a gap between two flats of the annular flat vane; the height of the locating rod is slightly smaller than the half of the height of the annular flat vane, and the height of the traction rod is slightly more than the half of the height of the annular flat vane; the main shaft is vertically mounted in the center of the rotary table. The rotary table is driven by power to rotate to drive the flat vane to do semi-cycle movement in the casing, movement effects and mirror surface effects, similar to that insects unfold quickly and flutter mutually can be generated, and the efficiency is higher.

Description

Technical field [0001] A ship propulsion device with a spring and a half-rotating annular flat blade belongs to the technical field of ships, in particular to a ship propulsion device. Background technique [0002] Traditional ship propulsion devices mostly use propellers. Although they are convenient to drive, they are low in efficiency. The blade manufacturing process is complex and will produce wakes when used. When using traditional paddle wheel propulsion devices, there is water splashing, with large splashes and rigid blades. 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 the authorized announcement number CN100360378C discloses a bionic flat-plate ship propeller, which is more efficient but has a more complicated structure. Summary of the invention [0003] The purpose of the present invention is to overcome the above...
