JPH01107000A - Pump applied flapping mechanism of bee - Google Patents

Abstract

PURPOSE:To provide a high efficiency pump by modeling two-dimensionally a flapping mechanism of small bee to apply the mechanism to a new pump. CONSTITUTION:After two wings 1 are closed together, they are rotated about their rear edges. Then, both wings 1 have a certain angle of incidence and make translational motion to be kept away from each other. When both wings 1 reach a wall surface 2, then both wings are rotated abut the front edges until they become parallel to each other. Thereafter, both wings 1 are opened about the rear edges, made move parallelly, rotated centering the front edges at the central portion of water path, and closed together. Then, they return to the initial condition and this process is repeated.

Description

DETAILED DESCRIPTION OF THE INVENTION Currently, various types of pumps are used for various purposes, including positive displacement types, turbo types, and other special types.

This project aims to develop a highly efficient pump by applying the efficient lift generation mechanism of bees during stationary flight to a pump.

Hereinafter, the principle of the present invention will be explained based on the illustrated schematic diagrams. FIG. 1 is a schematic diagram showing the movement of two blades, which is the principle of the present invention. The shaded area in FIG. 1 is the wall surface of the rectangular waterway, and the blade is shown in cross section.

First, in (a), after the two wings are closed together, (
Rotate around the trailing edges of both wings as in b). Then, as shown in (c), both wings move in parallel with a certain angle of attack and move away from each other. Then, as shown in (d), when both wings reach the wall surface, they rotate around the leading edge of each wing until they become parallel, as shown in (e). After that, as in (f), it opens around the trailing edge and moves in parallel as in (C), and closes by rotating around the leading edge in the center of the waterway as in (g).

After this, return to (a) and repeat this process.

The fluid flows from the top to the bottom of FIG.

The movement of these blades is similar to the movement of a gourd, but in the present invention, the interaction between the two blades instantly generates large circulation in both blades, efficiently pressurizing the fluid and moving it downward.

In fluid mechanics, there is something called the mirror image principle.
J. The same effect can be obtained by replacing the plane of symmetry of the two wings that move symmetrically with a solid wall. Therefore, as shown in Figure 2, one wing moves in the same way as in Figures 1 (a) to (g) in a water channel similar to the one in Figure 1 where the center of the water channel has been replaced with a wall surface. do. The wings shown in dotted lines in FIG. 2 are mirror images and do not actually exist.

Further, as shown in FIG. 3, the present invention can be installed in several stages in series to increase the head.

Claims (2)

[Claims] (1) Create a two-dimensional model of the flapping mechanism of bees and apply it to a new pump. That is, after the two blades collide in the waterway, they rotate symmetrically around their trailing edges to open up to a certain angle, and then move in parallel while maintaining that angle. When the wing approaches the wall of the waterway, it rotates around the leading edge of the wing and closes. A pump that uses the above mechanism to supply or pump water by applying pressure to water or other liquids. (2) The pump according to claim (1), which uses two symmetrically operating blades to produce the same effect with one blade.
