Technical field
The utility model relates to a kind of wind-driven generator.
Background technique
Wind-power electricity generation is as renewable resources, its have pollution-free, the power generating equipment input is less relatively, the mounting point requires loose relatively etc. advantage.Therefore increasing people utilize wind-force to generate electricity.The working principle of wind-driven generator is: promote fan blade by wind-force, drive generator by fan blade again and generate electricity.But survey because wind is strong and weak difficult, in some cases even can make fan blade stop operating.In a single day fan blade stops operating, and restarting until generating from halted state needs the very long and process of a large amount of power consumptions, produces the problem of starting difficulty after the stall.Existing common wind-power electricity generation all can't be avoided this problem.
Summary of the invention
The utility model provides a kind of wind-driven generator that fan blade still can rotate under weak wind state.
For achieving the above object, the utility model has been taked following technological scheme:
A kind of wind-driven generator of calm starting low speed generating comprises fan blade and generator, especially, also is provided with starting arrangement, engaging and disengaging gear, tachogenerator and control circuit; Engaging and disengaging gear is arranged between starting arrangement and the fan blade; Starting arrangement can drive fan blade by engaging and disengaging gear and rotate; Starting arrangement and tachogenerator respectively with the control circuit conducting; Control circuit is connected to power supply, according to the information of tachogenerator the working state of starting arrangement is controlled.Described power supply can be a storage battery.
Under the stronger situation of wind-force, starting arrangement is not worked, and only directly promotes fan blade by wind-force and generates electricity.Under the more weak situation of wind-force, control circuit can know that fan blade is in the information of lower-speed state by tachogenerator, and then starts starting arrangement.Starting arrangement can drive fan blade through engaging and disengaging gear and rotate, and makes fan blade maintain the state of generating transition point and is unlikely to stop fully.When the wind grow, the rotational velocity of fan blade will accelerate, and this moment, control circuit knew that by tachogenerator fan blade is in the information of fast state, stopping-starting device.
Above-described engaging and disengaging gear refers to the device that can change drive state between starting arrangement and the fan blade, and not limiting must physical separation between starting arrangement and the fan blade.Should also be noted that starting arrangement only drives fan blade and rotates when wind-force is very weak, avoid fan blade to stop fully; Under the situation of wind-force grow, the become a common practice resistance of wheel rotation of not strain of starting arrangement.Therefore, engaging and disengaging gear should have the ability of unidirectional transmission generally speaking, that is: starting arrangement can drive fan blade and rotates towards a certain direction, and fan blade can oppositely not drive starting arrangement when rotating with the rotational velocity that is higher than starting arrangement in the same direction under wind-force promotes." a certain direction " described here refers to the predetermined rotation of fan blade when being designed.
Starting arrangement, tachogenerator and control circuit all need to consume certain electric power generally speaking, and their power source can be the storage battery that is used to save the generator electric energy.Though the electric energy that the electric energy that starting arrangement, tachogenerator and control circuit consumed under weak landscape condition can produce than the fan blade rotation is many, both gaps are very little, need not to expend the rotation that a lot of electric energy just can be kept fan blade.Fan blade is in the state of rotation all the time, avoided the difficult problem of starting after the stall, then wind-force a little less than, even under the conventional wind power generator situation that also is not enough to start, wind-driven generator of the present utility model just has the state that has been in generating, maximally utilises wind energy.
The energy consumption of the utility model utilization trace guarantees that wind-power generating system remains on the state of generating transition point, in case extraneous wind-force stack is arranged, immediately just can generate electricity, shortened the very long power consumption process from stopping to generating electricity, reduced requirement greatly to the generating wind speed, having improved the endurance and the output quality of system's generating, is a kind of wind-driven generator of high production capacity.
