Abstract
The utility model discloses a minitype wind power generating device. The minitype wind power generating device comprises an annular outer frame, wherein multiple groups of coils are embedded into the annular outer frame; a hub is arranged on the center position of the interior of the annular outer frame, the hub is connected with an impeller, and the impeller consists of multiple blades which are uniformly arranged; and the blades have magnetic property, and a gear change is not needed, so that the frictional resistance is small, the acting efficiency is improved, and the starting wind speed is reduced. The minitype wind power generating device provided by the utility model can operate so as to generate electricity at most of the time, thereby providing a real environmentally-friendly energy source for humans.
Description
Technical field
The utility model relates to a kind of wind power plant, is specifically related to a kind of small wind-driven generator.
Background technique
Traditional small wind-driven generator generally is comprised of generator, impeller, rudder stock, and impeller will slowly run by a speed change gear and pass to generator after changing high speed rotating into.Generator is exposed outside, and its axle head connects the wheel hub of impeller and adopts an air guide sleeve to prevent that dust from entering, and the other end of generator is connected on the other hand with rudder stock on the one hand and is connected with column.The relative hub spindle of the blade of impeller is to being vertical.Its deficiency has the following aspects:
1, in order to make generator higher rotating speed be arranged to reach maximum generation efficient, often adopt speed change gear, but speed change gear has increased mechanical resistance, improved the startup wind speed, increased manufacture cost, and easily damaged.
2, because generator speed is high, need to offer the radiation hole heat radiation, but radiation hole easily enters dust etc., cause generator to damage.
3, air guide sleeve only plays protective action.Be blade is carried out after the balance with the wheel hub installation when impeller is installed, be loaded on air guide sleeve.The wheel hub material is generally metal carbon steel or aluminum alloy, and hub diameter can not be done too large, otherwise the rotary inertia increase, general external diameter is no more than the generator external diameter.And air guide sleeve can only be contained on the wheel hub, forces air guide sleeve to do very littlely, and is very thin, very light.Be the rotary inertia that do not strengthen wind wheel and the balance quality requirement of secondary installing, force wheel hub, blade manufacturing, the installation precision of blower fan to require to improve, increased manufacture difficulty and the cost of blower fan.
The model utility content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of small wind-driven generator is provided, and this device generating efficiency is high, has use value.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of small wind-driven generator, comprise ring frame, evenly distributed on the described ring frame outer ring have to organize coils more, described coil setting party is to radially corresponding with described ring frame, described ring frame inside center position is provided with wheel hub, and described wheel hub is connected with impeller, and described impeller is comprised of the multi-disc blade of even setting, described blade band is magnetic, and the magnetic induction line direction is radially corresponding with described ring frame.
Preferably, described wheel hub is connected in described ring frame by many root posts, and described column is by described ring frame center, and an end is fixed in described ring frame inwall.
Preferably, described blade is light magnetic material.
Preferably, described blade is pasted with light magnetic material.
The beneficial effects of the utility model are:
1, ring frame has been embedded in copper coil, and blade adopts light magnetic material, so surface friction drag is little, and not fragile.
2, owing to not needing gear graduation, so surface friction drag is little, improves mechanical efficiency, reduces to start wind speed.
3, the utility model is in the most of time generating of can both turning round, for the mankind provide a kind of real eco-friendly power source.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
