Description

Device using asynchronous motor as wind-driven generator

The device that the utility model is made wind-driven generator with asynchronous motor is a kind of electricity generating device.

Present wind-driven generator mostly is synchronous generator or DC generator, and all because of the cost height, using scope is little for these generators, is unfavorable for promoting the use of widely, also is unsuitable for vast forest zone, and pastoral area and areas without electricity use.

The purpose of this utility model provides a kind of wind generating unit that vast areas without electricity uses that is suitable for, owing to its cost is low, practical, is convenient in the pastoral area, and the forest zone, use in the mountain area, is more convenient for utilizing vast rural area to utilize the asynchronous motor generating during slack season.

A kind of device of making wind-driven generator with asynchronous motor, it is characterized in that by the central axle sleeve of cyclone-type windmill ［ I ］ and asynchronous motor ［ III ］ respectively low with booster engine ［ II ］, high speed shaft joins, three phase terminals of asynchronous motor link to each other with automatic adjusting voltage stabilizer and form, when the wind more than three grades, the moving fan blade rotation of wind, the lower velocity shaft that drives booster engine rotates, and makes last grade high speed shaft quick rotation by the multi-stage acceleration mechanism speedup of booster engine, drives the asynchronous motor generating, and through regulating voltage stabilizer automatically, voltage stabilizing and coupling after the power back-off, obtain 380,220 or 110,24 volts voltage electricity consumption is used for various power plant, household electricity, or the charging storage, wherein the structure of each parts is as follows:

A kind of cyclone-type windmill of forming by three blades, it is characterized in that having a garden dish ［ 13 ］ that the garden is ring-like, the angle steel ［ 12 ］ of garden camber is installed on five equilibrium ground on the dish of garden, the fastening fan blade of the another side of angle steel ［ 11 ］, leaf flange ［ 14 ］ and fan blade, the garden dish tightens together, and combine with shaft flange ［ 15 ］ on being installed in low speed axle sleeve ［ 16 ］ by bolt, form a cyclone-type windmill, the garden dish also plays the collection wind action, the feature of this fan blade is that cross section is the plate of garden camber, and stiffening rib is arranged on the fan blade.

A kind of by seat, lid, axle, the booster engine that gear is formed, it is characterized in that having a sidewall band to drain the oil and lid is arranged on bolt ［ 10 ］ bolt, there is the block ［ 9 ］ of three to nine garden grooves the bottom surface, connect the case lid ［ 8 ］ that three to nine holes, garden are arranged equally by bolton on the block, install bearing ［ 2 ］ respectively in groove in the casing and the hole on the case lid, string is with lower velocity shaft ［ 1 ］ in the bearing, high speed shaft ［ 7 ］ and the gear shaft ［ 4 ］ of gearwheel ［ 5 ］ is housed, can pass head by what bolton was equipped with safety plug ［ 3 ］ on the case lid, the cover plate ［ 6 ］ of the low high speed shaft of tail, can from safety plug, inject oiling agent in the case, leave vent on the safety plug, drive a gear shaft by gearwheel when lower velocity shaft rotates and rotate until driving high speed shaft with another gearwheel and rotate, by the gear of the number of gear shaft and gearwheel and gear shaft than the gaining rate that determines rotating speed.This booster engine can be with iron and steel or nylon, reinforced plastic manufacturing.

Asynchronous motor is that the motor of commercially available various power is not discussed in this article; it is characterized in that doing generator uses; automatically regulating voltage stabilizer is that well-designed component constitutes; it is characterized in that by adjustable transformer T1 and driving mechanism; sampling; instruction; switching circuit is formed; when input supply voltage fluctuation and load variations; order about the positive and negative running of reversing motor by sampling instruction and switching circuit; and with reduction gear reduction rotating speed; drive the cursor slide of slide control; make output voltage keep constant; Fig. 6 T2 is the power transformer of controlling automatically; the L1 output voltage; through D1; C1; D2; supply with dc reversible motor M power supply behind the C2 rectifying and wave-filtering; K6 is the reduction voltage loop control knob; K7; BG1; BG2 is as electronic switch; L2 is through D3; behind the C4 rectifying and wave-filtering as the power supply of reference potential and sampling voltage; R3; Dw forms reference voltage circuit; reference potential takes out at the A point and receives BG1; the emitter R4 of BG2; DW; it is sample circuit that R5 forms bleeder circuit; sampling voltage is taken out at the B point and is received BG1 through R6; the working state of BG2; because first side winding is attempted by on the part winding of T1; its input voltage is with the variation of external power voltage; do corresponding the variation; and the reference potential that A is ordered is because of being subjected to the control of DW; when supply voltage makes when changing in the scope at certain spoke; the output voltage that A is ordered is a steady state value; when external power voltage raises; the corresponding rising of B point voltage; BG1; the BG2 base potential is higher than the emitter current potential makes the BG1 conducting; the BG2 cut-off current is along C1; K6; BG1; M forms the loop, makes motor M rotation, and the cursor slide that drives adjustable transformer moves to the step-down direction; output voltage is descended; the input voltage of T2 also descends at the same time, and sampling voltage and reference potential are tended to be balanced, after output voltage is setting valve; BG1 ends; cut off reduction voltage loop, motor stops operating, when external power voltage reduces; then electric current is along C2; M, BG2, K7 forms the loop; make the motor counter-rotating; the cursor slide that drives pressure governor moves to the direction of boosting, and after output voltage was whole value down, BG2 ended; the cut-out loop of boosting; motor stops operating, thereby no matter external voltage is to raise, still reduces; can both make the voltage protection of output terminal constant; utilize the remanent magnetism of the silicon steel plate in the threephase asynchronous to add the capacitive adapter according to the principle of electronic function clockwise and anticlockwise and the needs of magnetic force, internal regulation D wants overspeed, the outside adjusting by CJ and K2 control; because the coupling of this circuit reaches automatic adjusting; make motor send 380V, 220V voltage is by also exportable 12V of regulator potentiometer R7 and 24V.

Advantage of the present utility model has been to change the application area of asynchronous motor, be used in generator, whole apparatus cost is lower than generator, make a tractor serves several purposes, can utilize cheap wind-force, as herding, woods, mountain area and the power source that does not have the area, ground also can be in deficiency coastal and city generating compensates electric, energy saving.
