Abstract
The utility model discloses an artificial wind tunnel for wind power generation. The artificial wind tunnel for the wind power generation belongs to a small size wind generator and comprises a wind tunnel casing, a wind tunnel inner film, a wind tunnel wind inlet, a wind tunnel wind outlet, a wind wheel, a tail rudder, a steel frame and a universal base. According to the artificial wind tunnel for the wind power generation, low density wind energy is compressed into high density wind energy to generate power according to a wind tunnel principle. The wind tunnel casing which is in a wind-tunnel shape is made of iron pieces or nonmetal; the surface of the wind tunnel casing is performed corrosion and rust prevention processing; the wind tunnel wind inlet can be in a flat square or vertical square shape according to actual conditions of installation places; the wind tunnel wind outlet is in a round shape; wool felt which is served as the wind tunnel inner film is pasted inside the wind tunnel casing to reduce noise; blades of the wind wheel are changed from a single layer into at least two layers to increase a wind contact area; inclination of the blades is increased 2 to 3 degrees layer-by-layer; the wind tunnel wind outlet is provided with the tail rudder to enable the wind tunnel wind inlet to be towards the wind coming direction; the wind tunnel casing is fixed on the universal seat through the steel frame; the whole wind tunnel rotates along the wind direction; and the size of the wind tunnel casing can be determined according to installation places and requirements of users. The artificial wind tunnel for the wind power generation has the advantages of being high in efficiency, low in cost, small in size and wide in application range, being capable of working with the low density wind energy, being particularly suitable for northern China and northwest region and serving as preference of wind energy utilization devices.
Description
Technical field
The utility model relates to wind generating unit, and more particularly the utility model relates to a kind of artificial wind power generating wind-tunnel.
Background technique
Wind generating technology to be applied in China comparatively general, technical merit is also ripe, this novel environment friendly energy is admitted by society, and obtained using widely, the wind generating unit of China probably has four classes at present: a class is large-scale wind-driven generator, and rotor diameter is from tens meters to tens meters, this generator advantage is that generated energy is big, shortcoming is bulky, and weight is big, the expense costliness; Second class is medium-sized wind-driven generator, and rotor diameter is from several meters to tens meters; The 3rd class is small-sized wind power generator, and weight does not wait to 5 tons at 1.5 tons, and rotor diameter is mostly between 3.5 meters to 8.5 meters; The 4th class is microgenerator, and this wind turbine power generation amount is little, and cost is low, extensively is used in outlying mountain area, herds the illumination at family, cooking.
More than several big class wind generating units all be to draw wind energy power by enlarging rotor diameter, the wind energy that this mode absorbs is low-density wind energy mostly, processing through a lot of links just can reach the use standard again, according to wind-force size Qing Condition in recent years, the wind energy that is fit to the wind generating unit utilization is fewer and feweri, many big-and-middle-sized wind power plants that built and built can only leave unused, and have therefore caused bigger waste.
The model utility content
Provide a kind of artificial wind power generating wind-tunnel in order to solve the problems of the technologies described above content of the present utility model.
The utility model is achieved by following technical proposals:
Artificial wind power generating wind-tunnel of the present utility model comprises wind-tunnel shell, wind-tunnel inner membrance, wind-tunnel intake grill, wind-tunnel exhaust outlet, wind wheel, tail vane, steelframe, gimballed base.The utility model belongs to small-sized wind power generator, utilizing the wind-tunnel principle that the low density wind energy is compressed into the high density wind energy generates electricity, the wind-tunnel shell is with iron sheet or nonmetal making, antiseptic and rustproof processing is done on the surface, the wind-tunnel shell is the wind-tunnel shape, the wind-tunnel intake grill can determine flat side or perpendicular square shape according to the actual conditions of infield, the wind-tunnel exhaust outlet is rounded, be stained with in the wind-tunnel shell felt as the wind-tunnel inner membrance in order to reduce noise, wind wheel changes two layers or more blade into by general individual layer blade and is strengthening the wind face, the blade lean degree successively strengthens the 2-3 degree, tail vane is equipped with at wind-tunnel exhaust outlet place, be convenient to the wind-tunnel intake grill all the time towards the wind comes from, the wind-tunnel shell is fixed on the gimballed base with steelframe, and wind-tunnel integral body is along with wind direction rotates, the utility model is applied widely, as long as the low density wind energy is arranged, especially be fit to the Northwest, North China, specification can be decided according to infield and user's requirement.
The beneficial effects of the utility model are:
One, the utility model artificial wind power generating wind-tunnel utilizes wind-tunnel principle and two layers or more blade wind wheel structure with the direct boil down to high density of low-density wind energy wind energy, and wind energy utilization improves.
Two, artificial wind power generating wind-tunnel of the present utility model is equipped with tail vane and universal bearing, and intake grill is all the time towards the wind comes from.
Three, the utility model is from the row of volume and weight differentiation at small-sized wind power generator, and floor space is little.
Four, the utility model cost is low, and is applied widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front elevation of the wind wheel in the utility model.
Fig. 3 is the plan view of the wind wheel in the utility model.
Fig. 4 is the perspective view of the wind wheel in the utility model.
Among Fig. 1: wind-tunnel shell 1, wind-tunnel inner membrance 2, wind-tunnel intake grill 3, wind-tunnel exhaust outlet 4, wind wheel 5, tail vane 6, steelframe 7, gimballed base 8.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Wind-tunnel shell 1 usefulness steelframe 7 is fixed on the gimballed base 8 among Fig. 1, be stained with in the wind-tunnel shell 1 felt as wind-tunnel inner membrance 2 in order to reduce noise, wind-tunnel intake grill 3 is rectangle, wind-tunnel exhaust outlet 4 is rounded is convenient to install wind wheel 5, wind-tunnel shell 1 afterbody is equipped with tail vane 6, low density wind enters from wind-tunnel shell 1 and becomes high density wind to go out from wind-tunnel exhaust outlet 4 after compression, and the wind wheel 5 that is installed in wind-tunnel exhaust outlet 4 places absorbs, thereby reaches the purpose of generating.
