Abstract

The invention relates to a large-wind sail vertical rotation type wind power generation tower, and solves the problems of the existing wind driven generator, such as difficult effective matching between wind wheels and a generator and low wind wheel power. The large-wind sail vertical rotation type wind power generation tower comprises impellers composed of an upright shaft and a wind sail blade, and wind control shells arranged outside the impellers. The large-wind sail vertical rotation type wind power generation tower is characterized in that multiple impellers and wind control shells are arranged and are mounted in multiple frames respectively and installed together vertically; the upright shafts of all impellers are connected with each other; and the upright shaft of the downmost impeller is connected with the main shaft of a variable-power generator, thus forming the large-wind sail vertical rotation type wind power generation tower. The invention has the advantages that as the variable-power generator is connected with the upright shafts of the impellers, the problem of difficult effective matching between the generator and the impellers is solved, and the impellers can be matched with the generator under any wind force, thereby reducing dependence on wind and improving the wind wheel power and the generating efficiency.

Description

Big sail vertical rotating is wind power generation stepped

Technical field

The invention belongs to a kind of wind generating unit, particularly a kind of big sail vertical rotating is wind power generation stepped.

Background technique

At present, world energy sources day is becoming tight, and wind energy receives the many concerns of People more and more as a kind of clear energy sources.Existing wind-driven generator mainly is made up of wind wheel, tower bucket and generator.Wind wheel adopts three or more blade to constitute, and vanes fixed is on hub discs, and hub discs is installed on the tower bucket.This wind wheel is because the blowing area of blade is less, so each blade is all very long; Volume is very big, thereby the tower bucket is very high, the tower bucket of high-power wind-driven generator even up to more than 100 meters; Diameter reaches several meters, and the tower bucket rotates, and needs the huge bearing of several meters of diameters to support.The problem that this generator exists is: 1, technical requirements is high, and manufacture difficulty is big, and power is big more, and the difficulty of manufacturing is just big more.2, can not start voluntarily or low wind speed starts.3, power factor is low, and is strong to the dependence of wind, only could work preferably in the strong wind sky, is difficult to running at full capacity, and generating efficiency is low.

In order to address the above problem, I have developed sail type wind generator wind wheel, and have applied for that name is called the Chinese patent of " big sail vertical rotating wind turbines rotor ", and the patent No. is " ZL200920016105.0 ".The impeller of this patent is made of a vertically disposed vertical shaft and several vertically disposed sail blades; A retaining control wind shell is arranged in the outside of impeller; Retaining control wind shell is made of metal framework and the wind screen material that covers on the metal framework; The top of retaining control wind shell is fixed on the central shaft by positioning sleeve; The bottom is fixed on the base by positioning sleeve and pull bar or directly is fixed on the ground; On retaining control wind shell, an air inlet and an air outlet are arranged; Air inlet and air outlet correspond respectively to a sail blade; Other sail blade is then blocked by the sidewall of retaining control wind shell, in retaining control wind shell, forms the airflow channel that promotes the impeller rotation.It is impeller that this patent adopts the big sail crop rotation of vertical rotating, has increased blowing area, and has alleviated weight; Simultaneously, retaining control wind shell is set in the outside of impeller, on retaining control wind shell, intake grill and exhaust outlet is set; The flow direction to wind plays leading role; Thereby can utilize wind-force to greatest extent, and improved the impeller rotational speed, improved power factor and generating efficiency; And impeller to wind-force require low; Can not only start voluntarily, and have wind just can work, operational efficiency is high.But this patent also exists some problems, mainly is that wind wheel is the single-unit structure, and upper space is not effectively utilized, thereby the power of generating is restricted.In addition; The problem that power factor is low does not solve; Wind wheel is difficult to effective the cooperation with generator; At wind hour, the rotating speed of wind wheel is lower, thereby generator is difficult to running at full capacity; Generating efficiency is low; Dependence to wind is still bigger, and only in the strong wind sky during wind wheel oepration at full load, generator could normal work.

Summary of the invention

The technical problem that the present invention will solve is, overcomes the problem that wind wheel that existing wind-driven generator exists and generator are difficult to effectively to cooperate, wind wheel power is low, provides that a kind of wind wheel and generator are worked good, the high-power big sail vertical rotating of wind wheel is wind power generation stepped.

The present invention includes the impeller that constitutes by vertical shaft and sail blade; And the retaining control wind shell that is installed in the impeller outside; Its special way is; Described impeller has several with retaining control wind shell; Plurality of impeller is installed in respectively in several frameworks with retaining control wind shell, and is vertically mounted on together, and the vertical shaft of each impeller interconnects; The vertical shaft of nethermost impeller is connected with the main shaft of variable power generator, and it is wind power generation stepped to constitute big sail vertical rotating.

Two round circular orbits are arranged on framework; Several road wheels are arranged at the bottom at retaining control wind shell; Two of road wheels are one group; Lay respectively on two round circular orbits in the framework; Bottom at retaining control wind shell also has the some groups of limited wheels between two round circular orbits, guarantees that road wheel moves on round circular orbit.

Described variable power generator has a shell; The generator that several different capacities are arranged in the enclosure; A gearbox is installed on the top of shell; Center at gearbox and shell is equipped with generator shaft; Master gear is installed on main shaft; A sliding gear is installed on each generator shaft; There is one to stir the shifting fork mechanism that sliding gear moves up and down in the outside of each sliding gear; Engagement through shifting fork mechanism control sliding gear and master gear or separate, thereby being connected or separating of realization main shaft and each generator shaft.

Described shifting fork mechanism has two sliding bars; A shift fork is installed on sliding bar; One end of shift fork matches with sliding gear; The other end has a long strip opening; Outside at gearbox is equipped with handle, in the inside of gearbox the eccentric wheel that is connected with handle is installed, and on eccentric wheel, has one to stir bearing pin; Stir the long strip opening that bearing pin is arranged in the shift fork end, drive shift fork and move up and down.

The invention has the advantages that:

1, adopt the variable power generator to be connected with the vertical shaft of impeller; The impeller rotation; Solved generator and be difficult to effective problem that cooperates with impeller; Wind-force hour; Impeller is connected with small power generator; When wind-force is big; Impeller is connected with high-power generator, and when wind-force was bigger, impeller was connected with many generators simultaneously; Therefore; No matter the wind-force size can both make impeller and generator mate each other, has guaranteed the proper functioning of generator, has reduced the dependence to wind; Improve generating efficiency, and solved the difficult problem of impeller startup.

2, impeller, retaining control wind shell and framework are vertically mounted on together; Reasonable use upper space, increased the area of impeller greatly, improved wind wheel power; Thereby improved the generated output of generator, its generated output has been compared with existing wind-driven generator and has been increased exponentially.
