Circumference magnet-cutting fluid power generation device

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...

Problems solved by technology

[0009] 2. Difficult to start, large loss and low efficiency

There are static friction and dynamic friction between gears. Static friction requires a large starting torque, while dynamic friction will cause friction loss and reduce energy conversion efficiency.

[0010] 3. Easily damaged

Due to its delicate construction, the gearbox has proven to be one of the most vulnerable parts and expensive to replace
