Abstract
The invention discloses a wind-driven generator automatic protection device which comprises a wind wheel, a support and a generator set. Blades, a blade handle and a hub are arranged on the wind wheel. The blade handle can rotate around its own axis relative to the hub. The generator set is provided with a control unit. The control unit comprises a storage battery set, a multi-way switch, a voltage detecting module and an execution module. The wind wheel is provided with a braking module which is used for conducting braking on the wind wheel according to commands of the execution module. The wind-driven generator automatic protection device has the advantages that when wind is too powerful, force is exerted to the blades, wind area is adjusted, and stalling due to the fact that rotation speed of the wind wheel is too high is avoided; when off line occurs between the wind wheel and the generator set, power generated by the wind wheel is switched to the storage battery set automatically, at the same time, the braking device is started to conduct braking on the wind wheel, and therefore the whole wind-driven generator is effectively protected.
Description
Technical field
The present invention relates to a kind of automatic safety device, be specifically related to a kind of wind-driven generator automatic protection device.
Background technique
In recent years, wind energy is sustainable as one, and developable new energy go on the stage of current energy field.Have a large amount of wind-driven generators to come out at present, but in actual motion, some high-power generator flabellums are long, the inconvenience causing production, transport and install, and manufacture cost is also very high, and the angle of blade is also fixing, if experience high wind, loss will be larger.
Moreover; when there is off-grid fault; impeller is high speed rotating still; larger vibration and load is caused in unit disorderly closedown process; and the existing methodical pneumatic damping mainly making vane rotary produce disappears more slowly; thus slow down the vibration of tower cylinder, but still comparatively large with vane rotary moment of torsion, be very easy to cause impeller to exceed the speed limit.
Summary of the invention
The object of the present invention is to provide a kind of wind-driven generator automatic protection device; by arranging flexible blade; loading angle is changed stressed to reduce when wind-force is excessive; and arrange energy absorption units absorb off-grid time vane rotary energy; damping vibration; overcome the above-mentioned deficiency of existing wind-driven generator, thus realize object of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of wind-driven generator automatic protection device, comprise wind wheel, support and generator set, wherein, wind wheel is provided with some blades, and blade is flexibly connected with wind wheel by a petiole; Petiole is arranged on the wheel hub of wind wheel, and petiole is provided with an initial position relative to this wheel hub, and petiole can relative to wheel hub rotation; Be provided with an elastic device at wheel hub and petiole joint, this elastic device is for the petiole that resets;
Generator set is provided with a control unit, control unit comprises a battery pack, multi-direction switch, voltage detection module, Executive Module, wherein switch terminals one end of multi-direction switch is arranged between wind wheel and generator set, the other end is connected with battery pack, and the control end of multi-direction switch is connected with Executive Module; Voltage detection module is located on generator set and is also controlled by Executive Module, and Executive Module is connected with the control end of multi-direction switch; Wind wheel is provided with a brake module, and this brake module is used for braking wind wheel according to the instruction of Executive Module.
In a preferred embodiment of the invention, elastic device is specially one or more spring members, and this lower spring parts one end connects petiole, and the other end is connected with wheel hub.
In a preferred embodiment of the invention, between wheel hub and petiole, be provided with the first sealing mechanism, between generator set and wind wheel, be provided with the second sealing mechanism.
Beneficial effect of the present invention is:
When wind-force is excessive, vane stress adjustment blowing area, avoids that wind speed round is too fast causes stall; When wind wheel and generator set generation off-grid, automatically the electric power that wind wheel produces is switched to battery pack, start braking device simultaneously and wind wheel is braked, the whole wind-driven generator of available protecting.
