Abstract
Disclosed is a wind turbine self-adjustable blade, which arranges a blade on a blade shaft lever; and the blade can be axially rotated. The upwind angle of the self-adjustable blade can be controlled by a torsion spring, so that the wind energy utilization rate and the safety factor of the generator during operation can be improved.
Description
Technical field
The utility model relates to a kind of mode of horizontal axis wind-driven generator blade installation, especially can make wind-driven generator improve utilization ratio of wind energy, makes the blade of the safer work of generator.
Background technique
At present, known blade of wind-driven generator is to be directly installed on the generator horizontal axis after machining is shaped.When wind speed reaches the starting wind velocity of generator, the generator generating of just starting working.When wind speed reaches the maximum wind speed of generator qualification, generator there is impaired danger.Common blade can only guarantee wind-driven generator proper functioning between starting wind velocity and maximum wind speed, and low and dangerous to utilization ratio of wind energy, narrow limitation is big.
Summary of the invention
In order to overcome the deficiency that existing blade is low to wind energy utilization and danger is big, the utility model provides a kind of adjustable vane voluntarily, and it can not only improve generator to utilization ratio of wind energy, and makes generator safer.
The technological scheme that its technical problem that solves the utility model adopts is: the vertical fixing installation on generator shaft earlier of blade axostylus axostyle, blade and torque spring are contained on the blade axostylus axostyle, blade can serve as that axle rotates with the blade axostylus axostyle, torque spring is pressed in blade on the blade axostylus axostyle with certain torsion when mounted, torsion increases during blade rotation, and by torsion control blade angle, sharf pole pair blade works to support and transmit rotating force.Adjustable vane is compared common blade and is enlarged the windward side on the one hand voluntarily, thereby improves utilization ratio of wind energy.On the other hand when meet wind speed increasing during until typhoon common blade because thereby the resistance of the constant generation of wind-exposuring area is increasing, to the generator danger close.When adjustable vane voluntarily to the resistance of wind during greater than the torsion of torque spring, blade can axially rotate counterclockwise on the blade axostylus axostyle, and the windward side is diminished, air resistance coefficient diminishes, thereby reduces resistance.To generator play protection effect and can proper functioning, reach and improve wind energy utilization and safer purpose.
The beneficial effects of the utility model are, can make wind-driven generator Applicable scope wider, and utilization ratio of wind energy is higher, and safety and reliability, and is simple in structure.
Description of drawings
Further specify with the utility model below in conjunction with drawings and Examples.
Fig. 1 is embodiment's tectonic maps of the present utility model.
Fig. 2 is the I--I sectional view of Fig. 1.
1. blades among the figure, 2. blade axostylus axostyle, 3. torque spring.
Embodiment
In the embodiment shown in fig. 1, blade (1) is stuck on the blade axostylus axostyle (2) after torque spring (3) is rotated an angle.Make blade (1); Blade axostylus axostyle (2); And torque spring (3) is connected firmly, and finishes adjustable vane assembling voluntarily.
Claims (2)
1. wind-driven generator adjustable vane voluntarily, blade axostylus axostyle earlier on generator shaft vertical fixing install, blade and torque spring are contained on the sharf pavilion, it is characterized in that: blade can serve as that axle rotates with the blade axostylus axostyle.
2. adjustable vane voluntarily according to claim 1 is characterized in that: torque spring is pressed in blade on the sharf pavilion with certain torsion when mounted, and torsion increases during blade rotation.
