Abstract
The invention discloses a low-speed wind turbine generator. In the generator, a bracket is arranged on the upper end of a base; a generator is arranged on the bottom end of the bracket; the upper end of the generator is provided with a transmission shaft; the lower end of the transmission shaft is arranged on a rotor shaft of the generator through connection of a connecting plate; the upper end of the transmission shaft is provided with a wind turbine shaft; the lower end of the wind turbine shaft is provided with a support shaft sleeve, while the upper end is provided with a wind turbine; and when the low-speed wind turbine generator is used, the base can be arranged on the roof of a one-storey/two-storey house, an arc impeller blade absorbs natural wind from different directions to generate wind power which is ten times higher than that of a traditional fan, and the wind power is transferred into a larger moment to drive the unit to generate electricity and apply work.
Description
Technical field
The present invention relates to a kind of wind energy power machine, definite a kind of low speed wind power generator of saying so.
Background technique
China is in the region, subtropics, is in 2 places to gentle breeze speed all the year round and accounts for more than 70 percent of national area, the wind energy conversion system of using at present; Its wind energy power blade mostly adopts three traditional blade structures; The wind energy conversion system of this structure, because blade is rare, the wind energy of from wind speed, obtaining is less; Effective wind speed needs can move generating more than the level Four during work, can't be in regional this natural wind resource of utilization and extention of weak wind.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; A kind of low velocity wind energy power electric generator of being made up of the high pulling torque wind wheel blade is provided; To solve the problem that existing wind energy conversion system low speed wind power can not normal power generation, realize the normal operation under the low wind friction velocity, outwards carry wind energy electric power.
Scheme of the present invention is by base, support, transmission shaft, rotor shaft, link press span, wind wheel and generator are formed up and down, and its structural feature is that support is equipped with in the upper end of base, and the bottom of support is provided with generator; Generator is fixedly mounted on the base, and the upper end of generator is provided with transmission shaft, and the lower end of transmission shaft is mounted on the rotor shaft of generator by land; The upper end of transmission shaft is connected with rotor shaft; The lower end of rotor shaft is provided with support sleeve, and wind wheel is housed on the rotor shaft, and wind wheel is formed unit head by the stack mounting of four groups of camber impeller blades on rotor shaft; The upper and lower end of camber impeller blade is provided with the frame that reinforces the connection; The camber impeller blade is provided with the camber support, and four groups of impeller blades are fixedly mounted on the rotor shaft by lonely type support, and the camber support is provided with the air door alive of a plurality of activities; The air door of living is installed in by hinge on the camber support of camber impeller blade, and the lower end of the air door of living is provided with limiting stopper.
During use, can base be installed on the roof of one, two layer of one-storey house, absorb natural wind, convert wind power energy to, produce bigger moment, drive unit generation and do manual work greater than tens of times of traditional three blade blower fans from different direction by the camber impeller blade.
The present invention is simple in structure, and is reasonable in design, and wind wheel blade work is not limited by wind direction, and need not tail vane, and it is big to obtain wind energy, and using effect is good, and is of many uses, can form the wind-driven generator of all size power, is used for various device and electrical equipment.
Do further explain below in conjunction with accompanying drawing.
