AI Technical Summary
Technical Problem
Existing fluid transfer devices, such as axial flow pumps, do not effectively provide a propulsive force to fluids in the direction of flow, and there is a need for a power generation device that can also function as a fluid transfer device.
Method used
A fluid transfer device comprising a cylindrical body with a magnetic body forming an annular cross-section magnetic field and a cylindrical coil within this field, where multiple magnets arranged at intervals rotate to impart a propulsive force to the fluid, acting as blades or propellers, and can also generate power.
Benefits of technology
The device provides a propulsive force to fluids in the direction of flow and can function as a power generator, offering efficient fluid transfer and energy conversion.

Abstract
To provide a fluid transfer device which gives propulsive force in a flow direction to fluid flowing inside a fluid transfer pipe comprising a cylindrical body.SOLUTION: A fluid transfer device is provided with a magnet body forming a cross-sectionally annular field, and a cylindrical coil extending in the flow direction in the cross-sectionally annular field by the magnet body. The field is formed between a cylindrical stator part and a cylindrical rotor part extending in the flow direction while sandwiching the cylindrical coil therebetween in a radial direction. The magnet body comprises a plurality of magnets arranged in the peripheral wall surface of the rotor part facing the stator part by sandwiching the cylindrical coil in between. The plurality of magnets are constituted due to that a plurality of magnet rows extending in parallel to the flow direction at a prescribed interval therebetween in the circumferential direction of a rotor are arranged on the peripheral wall surface in a direction oblique to the flow direction. An angle θ made between line segments extending obliquely intersecting in the flow direction between the magnet rows adjacent in the circumferential direction, and the flow direction is 5 degrees to 85 degrees. The plurality of magnets constituting the magnet body are rotated in the circumferential direction by electrifying the cylindrical coil so as to apply propulsive force.SELECTED DRAWING: Figure 1
