Description

The high-altitude orbit sailboard wind energy conversion system

Technical field

The utility model relates to a kind of wind generating unit, is specifically related to a kind of sailboard type wind generating unit.Wind generating unit of the present utility model sets up ring track by some pylon combinations in the high-altitude, can support the safe operation under different wind-force of big footpath sailboard type wind generating unit.

Background technique

Current, along with the exhaustion of non-renewable energy resources such as coal, oil, rock gas, new energy such as solar energy, wind-force are paid attention to by people gradually, and these class new energy have cleaning, do not produce the feature of pollution, and resource can be described as inexhaustible.Wherein, wind-power electricity generation is a kind of green energy resource that has development potentiality, can effectively solve China rural area and the expensive problem of remote mountain areas people's power shortage electricity consumption.

The wind-driven generator that uses no matter be horizontal shaft type or perpendicular axis type, all is to rely on the central shaft of wind-driven generator to support fan blade weight at present.Like this, when fan blade was big more, the moment vertically downward that produces between fan blade center of gravity and the wind-driven generator central shaft was just big more, and this power has destruction to wind-driven generator, therefore, the fan blade length that can bear of existing wind-driven generator is limited.

For a long time, people attempt to improve the wind-power electricity generation benefit by increasing rotor diameter and increasing the unit volume of passenger traffic that the pylon height increases wind-driven generator always.Yet, because the center of gravity of single tower support wind wheel rotation is higher, make that the scope that can swing is very narrow, there is great potential safety hazard, the above wind speed of 20 meter per seconds could utilize, and have to take the stall measure, hopes strong wind heave a sigh! It is more and more difficult to cause single-machine capacity to increase.

Summary of the invention

The purpose of this utility model provides a kind ofly takes advantage of the high-altitude orbit sailboard wind energy conversion system of sport car rotary electrification on the ring track that supports with some pylons by big footpath wind wheel, to increase the single-machine capacity of wind-driven generator under the prerequisite that guarantees the wind energy conversion system safe operation.

High-altitude orbit sailboard wind energy conversion system of the present utility model comprises the center pylon, the annular pylon, ring track, sport car, lower floor's rotary arm, the upper strata rotary arm, pull bar, the negative and positive windsurfing, swing pinion, overdrive gear and generator, two or more annular pylons are the center of circle with the center pylon, be looped around the central tower frame peripheral, being equipped with one on the top of annular pylon is the horizontal annular track in the center of circle with the center pylon, sport car places on the ring track, even number root lower floor rotary arm is installed on the sport car, center along ring track is radially evenly arranged, with the lower floor identical parallel just folded top that is installed in lower floor's rotary arm of upper strata rotary arm of rotary arm quantity, on every group, the heteropleural at following rotary arm two ends respectively is equipped with a negative and positive windsurfing, swing pinion is installed in the below of lower floor's rotary arm, concentric with ring track, overdrive gear and swing pinion engagement, and the connection generator, to drive generator for electricity generation.

Described negative and positive windsurfing is made up of a slice windsurfing sheet at least, and the windsurfing sheet is a rotatingshaft with a long limit on the negative and positive windsurfing, and installation one side at rotary arm horizontally rotates only.Wherein, the windsurfing sheet of choke one side negative and positive windsurfing is rotated the arm of force and blocks, and intersects with the wind-force line, and resistance is bigger, promotes the rotary arm rotation; The windsurfing sheet of the negative and positive windsurfing of a side rotates with the wind according to the windsurfing rotatingshaft with the wind, and with the wind-force line parallel, resistance is less.

Described high-altitude orbit sailboard wind energy conversion system also comprises the hydraulic lift that is installed in center pylon and annular pylon bottom, and the hydraulic lift system rises or center pylon and annular pylon fall in system, so that ring track remains level.

The support system of the utility model high-altitude orbit sailboard wind energy conversion system is to be combined as big footpath right cylinder by two or more annular pylons and ring track, make the center of gravity of upper and lower layer rotary arm reduce, but hunting range is wide in range.Wherein, every group of upper and lower layer rotary arm is fixed into triangular structure with pull bar respectively, between the upper and lower layer rotary arm at a distance of 4～6 meters.

Described overdrive gear and generator can be installed in any position on the high-altitude orbit sailboard wind energy conversion system, and the utility model is that it is installed in top on the pylon of center.

There is data to show, when 2 grades of ground wind-force, during wind speed 2.6 meter per seconds, 5～6 grades of vertical lifting to 100 meter aerial wind-force, wind speed 8.7 meter per seconds, 8～12 grades of the wind-force of vertical lifting to 150 meter, wind speed 26 meter per seconds.

If the high-altitude orbit sailboard wind energy conversion system is that single tower windsurfing wind energy conversion system of 100 meters combines by 16 rotor diameters, then pylon can increase 1 times, and wind speed increases 1 times, and rotor diameter increases 1 times, and choke windsurfing sheet number increases by 3 times.

Hence one can see that, and the energy that the high-altitude orbit sailboard wind energy conversion system after the combination receives is 4 times of single tower windsurfing wind energy conversion system, only with regard to single-machine capacity, then increased 63 times.Can partly be changed additionally by the rotary arm saving and pylon increases employed steel, therefore, the economic benefit of high-altitude orbit sailboard wind energy conversion system has improved 3 times.

But the center of gravity hunting range of single tower windsurfing wind energy conversion system has only 0.5 meter, but the center of gravity hunting range of high-altitude orbit sailboard wind energy conversion system save your breath and also have 50 meters, safety coefficient is more than 100 times.Because wind wheel horizontally rotates, centrifugal acceleration does not superpose with gravity accleration.Centrifugal force increases the destruction that brings only 2 times, and after offseting, the ability of high-altitude orbit sailboard wind energy conversion system safe operation has improved 98 times.Make the above wind-force of 20 meter per seconds become the wind speed of wind energy conversion system safe operation, generator capacity increases with geometrical progression.

High-altitude orbit sailboard wind energy conversion system of the present utility model is simple in structure, cheap, can utilize high altitude wind to generate electricity safely and effectively.
