Abstract
The invention discloses a vertical type wind driven generator with long service life and high efficiency, and relates to the technical field of the wind power generation. On the basis of an ordinary vertical type wind driven generator, the wind driven generator is added with an electromagnet fixed on a substrate and used for supplying power to a constant current source; a non-contact electromagnetic force is generated through an electromagnet to counteract the gravity of a rotor of the wind driven generator. Therefore, the axial load and the frictional loss of the rolling bearing can be largely reduced, the service life of the rolling bearing and the efficiency of the wind driven generator are remarkably improved, and the application scale of the wind driven generator is enlarged.
Description
Technical field
The invention belongs to technical field of wind power generation.
Background technique
It is outstanding that the energy of our times property and environmental problem more show.Wind-driven generator has bigger application prospect as a kind of clean energy resource generation device, has received widely paying close attention to.The supporting part of rotor is one of critical component of wind-driven generator, is that surface friction drag is little, the life-span is long to its basic demand.
Existing vertical-type wind-driven generator generally adopts blade part directly to link to each other with alternator shaft, constitutes rotor, and through the roller bearings rotation.This structure makes rolling bearing not only will bear wind load (being generally radial load), also must bear the gravitational load (thrust load) of rotor, so surface friction drag is big, and the life-span of rolling bearing is low, and complete machine startup wind speed is high, and efficient is low.
In order to address this problem, existing researcher proposes to adopt permanent-magnet type magnetic bearing (claim not only permanent-magnet type magnetic suspension bearing) or active magnetic bearing (but also claiming active magnetic suspension bearing) support rotor.Little, the poor stability of permanent-magnet type magnetic bearing rigidity, and shortcomings such as permanent-magnet material costs an arm and a leg, poor processability, existence demagnetization are restricted its application.And active magnetic bearing needs a whole set of automatical control system, and system complex and cost are high.
Summary of the invention
The objective of the invention is to propose a kind of simple and the long lifetime and the high efficiency vertical-type wind-driven generator that are easy to realize.
This long lifetime and high efficiency vertical-type wind-driven generator comprise a rolling bearing and rolling bearing that bears radial load that bears radial load and thrust load simultaneously of pedestal, rotor and this rotor of support; It is characterized in that: this vertical-type wind-driven generator also comprises armature and electromagnet; Wherein armature and rotor are fixedly connected, and electromagnet and pedestal are fixedly connected, and electromagnet and armature residual gap keep fixed range, and the suction between electromagnet and the armature equals or approach the gravity of rotor 1.
This long lifetime and high efficiency vertical-type wind-driven generator; Its characteristic also is: above-mentioned electromagnet has the groove of loop configuration; Be fixed with the enameled cable winding through epoxy resin in the groove; The enameled cable winding is passed to fixedly direct current (d.c.) through [constant, and fixedly the size of direct current (d.c.) is by the gravity decision of rotor.
This long lifetime and high efficiency vertical-type wind-driven generator, its characteristic also is: above-mentioned armature is loop configuration.
The present invention is on general vertical-type wind-driven generator structure basis; Increase the electromagnet of the constant current source power supply that is fixed in pedestal; Produce contactless electromagnetic force through electromagnet, offset or basic neutralisation blower fan gravity, make rotor with agravic or approach null-gravity state and under roller bearings, rotate; Therefore the thrust load and the surface friction drag of rolling bearing reduce greatly; The life-span of rolling bearing significantly increases, and can effectively reduce the startup wind speed of wind-driven generator and improve overall efficiency, enlarges the application area (use in the area in that annual mean wind speed is lower) of wind-driven generator.
