Abstract

The utility model discloses a but real -time change blade angle's vertical axis aerogenerator blade device, the utility model relates to a low to present aerogenerator generating efficiency, low problem is rateed to wind energy utilization, and it is simple to provide a control, coordinates the angle that the gear train drove attack angle of blade control link mechanism real -time change blade through the rotational speed and realizes that the blade all has the best angle of facining the wind in the optional position, makes the blade catch the biggest wind energy, and the wind energy utilization who improves the wind energy conversion system is rateed. It is low to solve present aerogenerator generating efficiency with the expectation, and low problem is rateed to wind energy utilization.

Description

The vane of vertical shaft wind-driven generator device of blade angle can be changed in real time
Technical field
The utility model relates to technical field of new energies, is specially the vane of vertical shaft wind-driven generator device that can change blade angle in real time.
Background technique
At present, though existing wind-driven generator enters the practical stage, but Problems existing is, generating efficiency is low, and wind energy utilization is low, poor practicability, and problem in the urgent need to address is at present, how to improve the utilization ratio of generator to wind energy, reduces costs.Traditional wind generator design thinking is, designs a kind of wind turbine blade to increase the lift of wind, and reduce resistance, always limitation adopts fixing airfoil fan, and resistance is difficult to reduce, and the wind energy utilization of wind-driven generator is lower.
Summary of the invention
The present utility model is low for existing wind turbine power generation efficiency, the problem that wind energy utilization is low, provide a kind of control simple, coordinate by rotating speed angle that gear set drive attack angle of blade control link mechanism changes blade in real time to realize blade and have best Windward angle at an arbitrary position, make blade catch maximal wind-energy, improve the wind energy utilization of wind energy conversion system.Low to existing wind turbine power generation efficiency to be solved, the problem that wind energy utilization is low.
The utility model adopts following technological scheme to realize, and can change the vane of vertical shaft wind-driven generator device of blade angle in real time; Mainly comprise rotating speed and coordinate gear train, attack angle of blade control link mechanism, generator blade and equipment rack; Described rotating speed is coordinated gear train and is made up of central gear and peripheral gear; It is characterized in that: equipment rack is provided with rotating speed and coordinates gear train, rotating speed is coordinated gear train and is connected four generator blades by four attack angle of blade control link mechanisms; Described rotating speed is coordinated gear train central gear and is connected rotating speed coordination gear train peripheral gear, and rotating speed is coordinated gear train peripheral gear and connected attack angle of blade control link mechanism, and attack angle of blade control link mechanism connects generator blade.
The utility model has the advantages that: by controlling the best Windward angle (angle of attack) of blade in real time, effectively realizing blade and catching maximal wind-energy, effectively improving the wind energy utilization of wind energy conversion system.Have installation center of gravity concurrently low, easy for installation, easy to maintenance, the feature that symmetrical configuration, wind energy utilization are high simultaneously.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
Reference character: (1). rotating speed coordinates gear train; (2). attack angle of blade control link mechanism; (3). generator blade; (4). equipment rack; (5). rotating speed coordinates gear train central gear; (6). rotating speed coordinates gear train peripheral gear.
Embodiment
As shown in Figure 1 and Figure 2, the utility model realizes like this, can change the vane of vertical shaft wind-driven generator device of blade angle in real time; Mainly comprise rotating speed and coordinate gear train 1, attack angle of blade control link mechanism 2, generator blade 3 and equipment rack 4; Described rotating speed is coordinated gear train 1 and is made up of central gear 5 and peripheral gear 6; It is characterized in that: equipment rack 4 is provided with rotating speed and coordinates gear train 1, rotating speed is coordinated gear train 1 and is connected four generator blades 3 by four attack angle of blade control link mechanisms 2; Described rotating speed is coordinated gear train central gear 5 and is connected rotating speed coordination gear train peripheral gear 6, and rotating speed is coordinated gear train peripheral gear 6 and connected attack angle of blade control link mechanism 2, and attack angle of blade control link mechanism 2 connects generator blade 3.
Utility model works principle, rotating speed is coordinated gear train central gear 5 and is driven peripheral gear to rotate 6, peripheral gear drives 6 attack angle of blade control link mechanisms 2 to control tip speed ratio in real time and blade Windward angle makes blade have best Windward angle (angle of attack) in any position, effectively realize blade and catch maximal wind-energy, effectively improve the wind energy utilization of wind energy conversion system.
