Abstract

The utility model discloses an enhancement pneumatic type wind generator, which comprises blades and an impeller, wherein the blades are arranged on the edge of the impeller. The enhancement pneumatic type wind generator further comprises a pointed cone-shaped diversion cone, wherein the diversion cone is arranged on the front portion of the impeller in a mode of forward point end, and the impeller is also arranged on the impeller in the mode of forwardly inclined end portion. The outer end of the impeller of the enhancement pneumatic type wind generator forwardly inclined, is connected with the diversion cone to form high air pressure before the blades, thereby increasing driving force of air flow to the blades, and being further capable of increasing the wind power conversion efficiency.

Description

Strengthen the pneumatic-typed wind-driven generator
Technical field
The utility model relates to a kind of wind-driven generator, particularly a kind of wind-driven generator that can strengthen blast.
Background technique
Along with the fast development of national economy, energy shortage has become a problem that is on the rise, and wind energy development, development wind-power electricity generation are the research topics that current energy project receives much concern.As everyone knows, wind energy is present in nature, and it is caused by solar radiant heat, and solar energy impinges is to earth surface, causes the earth surface inequality of being heated, and produces the temperature difference, causes the convection current of atmosphere and forms wind.Wind is flow air, and it has speed, and density is arranged, so contain energy, wind is inexhaustible clean energy resource, but the randomness that wind energy distributes is very strong, does not have specific rule, in different regions, and Various Seasonal, the wind-force of different periods is all inequality.Because the unstability of natural wind energy, giving in the wind-powered electricity generation conversion needs the generator of stabilization of speed to bring very big difficulty, becomes the major technique obstacle of wind-powered electricity generation development.
The blade of present wind-driven generator impeller is install vertical with impeller shaft usually, blade surface and wind direction are an angle, wind produces pressure to blade and flows to the blade rear along blade surface when blade, blow the rotation of blade impeller, with wind energy transformation is mechanical energy, drive generator for electricity generation again, thereby again mechanical energy is converted into electric energy.For wind-driven generator, its minimum windspeed that reaches generator requirement rotating speed is called " rated wind speed ", " rated wind speed " of wind-driven generator is relevant with the conversion efficiency of the mechanical energy of generator and electric energy, also relevant with the wind energy utilization of impeller, when ambient wind velocity is lower than the rated wind speed of generator, be difficult to drive wind turbine power generation.
Therefore, improving the wind energy of impeller and the conversion ratio of mechanical energy, is the effective means that improves the wind-driven generator wind energy utilization.
The model utility content
The purpose of this utility model is to provide a kind of enhancing air pressure wind-driven generator, by blade wheel structure is improved, low blast wind energy is used effectively, and improves wind energy utilization.
The utility model adopts following technology: a kind of enhancing pneumatic-typed wind-driven generator, comprise blade and impeller, blade installation is at the impeller edge, it is characterized in that: also comprise cone-shaped guiding cone, guiding cone is installed in described impeller front portion in tip mode forward, and described blade also is installed on the impeller in the mode that the outer end turns forward.
The angle of described blade installation axis and impeller shaft is 60-80 °.
Described guiding cone drift angle angle is 60-120 °.
Enhancing pneumatic-typed wind-driven generator of the present utility model, by setting up guiding cone, (because the existence of guiding cone makes impeller diameter become big) makes wind energy footpath, impeller middle part outwards move on to the blade place when can increasing blade quantity, increase the blast at impeller place, the blade outer end turns forward, and with the guiding cone associating, constitutes the highpressure of blade front, it is moving to the thrust of blade to improve air-flow, thereby can further improve the wind-powered electricity generation conversion efficiency.
Description of drawings
Fig. 1 is the structural representation of enhancing pneumatic-typed wind-driven generator of the present utility model.
Fig. 2 is for strengthening the blade and the guiding cone working method schematic representation of pneumatic-typed wind-driven generator.
Embodiment
Below by specific embodiment the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, it is a kind of enhancing pneumatic-typed wind-driven generator, comprise blade 1 and impeller 2, blade 1 is installed in the edge of impeller 2, also comprise cone-shaped guiding cone 3, guiding cone 3 is installed in impeller 2 front portions in tip mode forward, and the mode that blade 1 also turns forward with outer end 1a is installed on the impeller 2.
As shown in Figure 2, wind when the impeller front (is all the time towards the direction of the wind comes from by tail vane and Yawing mechanism control impeller) is when arriving guiding cone 3, the wind F1 that blows to guiding cone 3 under the guiding cone guide functions changes direction and flows along the direction of cone 3 to blade 1, blow to blade 1, blade 1 front blast is increased, increased active force, and then increased torque impeller to blade.Because blade 1 is also installed with the direction that the outer end turns forward, the wind F2 that directly blows to blade produces pressure and then forms torque blade, a flow air part is walked around blade (blade 1 has an angle with respect to the direction of wind) directly to after-blow, one one to moving to the root of blade direction shown in the direction of arrow along the blade surface that tilts, this part wind has prolonged the action time to blade, blade front blast is increased, further improve blade front highpressure with the guiding cone associating, enhancing is to the Driving force of blade, thereby the wind energy of can further improve and mechanical switch efficient, impeller drives oil hydraulic pump 5 runnings by impeller shaft 4, keep pressure stable oil traffic driven oil hydraulic motor 7 by automatic flow control valve 9 and accumulator 6 and drive alternator 8 rotation generatings with stabilized (steady-state) speed, realization is converted into electric energy from mechanical energy, thereby improve the wind-powered electricity generation conversion ratio of generator, also also can under low wind speed, generate electricity simultaneously.Be that desired rated wind speed is lower than existing wind-driven generator.
More satisfactory is, the angle of blade installation axis and impeller shaft is that α is 60-80 °, and described guiding cone drift angle angle is that β is 60-120 °, to obtain rational pressurized effect.
