Description
Technical field
The utility model relates to a kind of wind energy utilization technology, especially a kind of small-sized wind power utilization device.
Background technique
Wind energy is that the Nature is the green energy resource that the mankind provide.People are largely to use wind using form to wind energy at present
Wheel, generates rotary force, for driving wind turbine power generation under wind energy；Also have and directly drive wind energy pump to be used to mention
It rises liquid (mainly water).
The structure type of wind wheel is divided into horizontal axis rotor and vertical axis rotor with wind wheel rotary shaft installation form.The wind of acquisition
Can be directly proportional to the wind sweeping area of wind wheel blade, therefore the diameter of wind wheel is all very big；Meanwhile wind generates lift simultaneously on wind wheel
And resistance, it is used in people that lift, which generates rotary force, and resistance must then be born by the vertical support rod of wind wheel group.Therefore, just
As people are seen, especially horizontal axis rotor unit is lifted by tall and big sturdy support rod, and support rod must be securely
Be mounted on solid ground.Meanwhile when wind speed is more than design maximum wind velocity, then fan blade must be locked, at this time wind wheel
Front face area is only equal to the front face area of blade, so that the windage for guaranteeing that vertical support rod is subject to substantially reduces and will not topple over.
Vertical axis rotor, is chiefly used in small-sized at present, but since its wind sweeping area is less than normal, because efficiency is lower, therefore use occasion is seldom.
To sum up, above-mentioned wind wheel apparatus has two big defects: first is that it is limited to available wind speed, it is especially biggish in wind speed
Special weather cannot use；Second is that position can only be fixedly mounted, immovable use.
So, in wind resource than more rich area, on smooth roof, long long river levee on the bank, boundless
Grassland on, both can independently use wind power utilization device, can be also used in combination with solar attachment, still be worth seeking
Target.
