Abstract
A kind of near-earth wind power generation plant.Using the shaped form reducing pipe at air collecting box four sides call prisoners in after letting them out for exercise mouth collect all directions come wind, make wind speed be greatly improved driving blower fan rotation, so as to effectively utilize low velocity wind energy generate electricity.The device can meet the demand that vast Urban Areas generates electricity to near-earth low velocity wind energy, effectively alleviate the nervous situation of low wind speed load center regional power supply.In addition, the quantities that the near-earth wind power generation plant is built is smaller, construction is simple, also is adapted for being applied and popularization as a kind of distributed power generation unit in remote districts.
Description
Technical field
The present invention relates to wind power generation field, and in particular to a kind of near-earth wind power generation plant.
Background technology
Wind energy is important renewable resource, and the current extensive wind energy development of China is rich in wind energy resources using area concentration
Rich high wind speed area, mainly includes the Inner Mongol central and north, southeastern coast and Some Regions, Xinjiang, and area is relatively narrow and small, and from negative
Lotus center is farther out.China has a big chunk area to have wind, but wind speed is relatively low throughout the year, and this kind of low velocity wind energy resource is more richly
Area is widely distributed in China, and the utilization of such low velocity wind energy has great importance for the development of wind-power electricity generation.
Conventional wind-driven generator is low for the utilization ratio of low velocity wind energy at present, is not suitable for installed in the wide of low wind speed
Major region.The need for meeting Urban Areas and remote districts to the generating of near-earth low speed wind power, a kind of near-earth wind-force is devised
TRT.
The content of the invention
Because the incision wind speed of traditional wind-driven generator is 3m/s, cause below 3m/s wind energy resources mostly unrestrained
Take.Low wind speed environments present invention is generally directed to wind speed in below 3m/s devise a kind of model wind generating device.The present apparatus
Wind speed can be improved so that below 3m/s wind energy resources can be converted utilization.
In order to the technical scheme realizing the purpose of the present invention and use for：A kind of near-earth wind power generation plant, including collection wind
Case, pitched cover, shaped form reducing pipe is called prisoners in after letting them out for exercise mouth, and air inlet, spiral duct, air outlet, reinforcing ring, tower, fan blade is led
Fan housing, generator, motor base, annular exhaust outlet.All directions come wind can by air collecting box four facing to shaped form gradually
Draw mouth of calling prisoners in after letting them out for exercise effectively is collected, and fan blade is blowed to through spiral duct, so that generator rotary electrification is driven, the gas after acting
Flow through the annular exhaust outlet of wind scooper flow direction, it is to avoid windage is excessive and influence air velocity in tower.
In order to improve the aggregate capabilities that air collecting box carrys out wind to surrounding, air collecting box four sides is called prisoners in after letting them out for exercise using shaped form reducing pipe
Mouthful, the shaped form reducing pipe call prisoners in after letting them out for exercise mouth be from four curved sheet materials constitute to air collecting box inner recess " horn-like " rectangle receive
Air port, forms streamline structure, as shown in Figure 1 in the binding site of adjacent mouth of calling prisoners in after letting them out for exercise.Called prisoners in after letting them out for exercise mouth using the shaped form reducing pipe,
The wind energy just called prisoners in after letting them out for exercise mouth to shaped form reducing pipe and come not only can be effectively collected, and due to Bernoulli effect, it is possibility to have
Imitate the other directions of collection carrys out wind, significantly improves the wind speed into spiral duct.
The utilization ratio of wind energy is converged for shaped form reducing pipe mouth of calling prisoners in after letting them out for exercise in order to improve the device, spiral duct is used
Cambered design, its air outlet is using the design just to fan blade tangent plane；Fan blade bottom installs wind scooper additional；Positioned at tower bottom
The exhaust outlet in portion uses annular design, leads to below tower outside tower, as shown in Figure 2.
The beneficial effects of the invention are as follows：Called prisoners in after letting them out for exercise mouth using shaped form reducing pipe so that air collecting box for surrounding to carry out wind equal
With efficient aggregate capabilities, and then significantly it is lifted into the air velocity of spiral duct；Air-flow is drawn through spiral duct
Lead, enter fan blade tangent plane with making airflow smooth, improve the utilization ratio of wind energy；The annular exhaust outlet design of large area, can
Reduce the windage in tower, make gas flowing more smooth；Reinforcing ring is by the air outlet fixation of four spiral ducts, such as Fig. 3
It is shown, it is possible to decrease the vibrations when present apparatus is operated, increase the stability of device, the service life of extension fixture；Pitched cover to
Upper raised slope design effectively can prevent rainwater from stockpiling；Fan blade and generator are placed in tower internal ground centre position,
To be installed in the form of ground, influence of the noise to surrounding environment is produced when reducing blower fan operating, it is to avoid blade turns
Influence of the sudden strain of a muscle shadow produced when dynamic to local resident, eliminates threat of the external blade to birds, reduces thunderbolt and ice and snow day
The natural causes such as gas are to the degree of injury of fan blade, while also making its maintenance more convenient and safe；Due to this dress
The suitable Urban Areas construction in low wind speed is put, this just makes it closer to load center, can nearby dissolve, reduce remote conveying
The loss of electricity.
The device has consumptive material few, highly low, the low advantage of cost, and being adapted to promote in the vast Urban Areas of low wind speed makes
With.It can alleviate the situation of load center power shortage to a certain extent in the construction and development of Urban Areas.In addition, should
The construction of near-earth wind power generation plant is smaller, and construction is simple, also is adapted in remote districts as a kind of distributed power generation
Device is applied and popularization.
