Embodiment Construction

[0049] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0050] The invention proposes a way to increase the radius of the generator, place the blades on the rotating surface, place the magnets and wires on the circumference of the rotor, capture the kinetic energy of fluids such as wind or water flow through the blades, drive the rotor to rotate, and the magnets and wires move relative to each other. A device that generates electricity.

[0051] On the premise of not using gears and transmission mechanisms, the present invention places magnets and wires at the circumference of the blade tip to perform "circumference-cut magnetic fluid power generation", and directly cuts the magnetic field lines by utilizing the characteristic of the...

Abstract

The invention discloses a circumference magnet-cutting fluid power generation device, which comprises a rotor, a stator and a rear-end processing circuit, wherein the rotor comprises a rotary bearing, a blade and an inner wheel; one end of the blade is connected with the rotary bearing, and the other end of the blade is connected with the inner wheel; the stator comprises an outer wheel and a supporting structure, which are connected with each other; a wire is connected with the rear-end processing circuit; a magnet is arranged on the inner wheel, and the wire is arranged on the outer wheel; or, the wire is arranged on the inner wheel, and the magnet is arranged on the outer wheel; and the blade is driven by fluid and stressed, the inner wheel rotates and moves relative to the outer wheel, and the wire cuts a magnetic force line which is generated by the magnet to generate induced electromotive force, so current is generated. According to the characteristic that the circumference of the inner wheel of the rotor has maximum line speed, the magnetic force line is directly cut for power generation, and the circumference magnet-cutting fluid power generation device can be applied to the fields of wind power generation, river power generation, wave power generation, tail gas power generation and the like, and is simple in structure, high in efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a kinetic energy power generation device utilizing wind, water flow, waves and other fluids. Background technique [0002] Among the renewable energy sources, the utilization of wind energy, water energy and wave energy occupies a very important position. [0003] Both air and water are fluids, and fluid movement has kinetic energy (for example, moving air produces wind energy, and moving water produces river water energy, river and sea tidal energy, ocean wave energy, etc.). [0004] The existing power generation technologies for wind and water mainly utilize their kinetic energy characteristics. First, the kinetic energy of the fluid is captured by the blades and converted into the mechanical energy of the impeller; then the mechanical energy is transmitted to the speed change mechanism through the transmission shaft to increase the speed; finally, the transmission sh...
