Distributed fluid energy-based electric power generation device

Abstract

The invention relates to a d istributed fluid energy-based electric power generation device comprising an electric power generator stator, an electric power generator rotor and blades; the electric power generator rotor comprises an annular rotor body, a central flow guiding body is arranged at a center of an inner circumference of the annular rotor body in a concentric manner, a circumference of the central flow guiding body is uniformly provided with a number of blades, and outer rims of the blades are connected with an inner wall of the annular rotor body; a number of axial direction fluid passage fluid flow channels are formed via respective enclosures of the blades and the central flow guiding body and the inner wall of the annular rotor body. According to a conventional electric power generator structure, fluid kinetic energy can be transmitted to an electric power generator only via arrangement of a transmission mechanism between an impeller and the electric power generator or arrangement of a speedup device; the annular rotor body can be directly driven to rotate via the blades of the electric power generation device disclosed in the invention, intermediate transmission links are eliminated, energy conversion efficiency is greatly improved, the electric power generator rotor is arranged on tail ends of fluid energy receiving blades, relative movement between a permanent magnet and a wire coil is effectively amplified, and mechanical energy consumption caused via arrangement of a speedup mechanism can be reduced by times.

Description

technical field [0001] The invention relates to the field of generator devices, in particular to a distributed current energy generating device. Background technique [0002] Since 2004, successive blackouts in the United States, Canada, the United Kingdom, Australia, Denmark, Sweden, Italy and other countries have profoundly demonstrated that there are serious technical defects in traditional energy supply forms. With the development of the times, especially the information society It is highly developed, and the traditional power supply form is no longer able to continue to support the development of human civilization. It is necessary to accelerate the establishment of a new energy system in the information age, and distributed energy will surely become the core technology of this system. [0003] Distributed energy is an energy development method that can best reflect multiple advantages such as energy saving, emission reduction, safety, and flexibility. China has a lar...
