Abstract
The utility model relates to a blade of 200 w wind-driven generators. The blade relates to the wind wheel of a wind-driven generator, and is especially suitable for the blade structure of the wind wheel of the 200W wind-driven generator. The material of the utility model is woody core and the surface layer of the woody core is coated with fiberglass reinforced plastic structure; the blade root adopts NACA4415 wing type; the blade tip adopts NACA4412 wing type; the included angle of the geometric chord line from the blade root to the blade tip is 15 DEG; the installing spiral angle of the blade root is 18 DEG; the chord length of the blade root is 200 mm; the chord length of the blade tip is 150 mm; the connecting portion of the root is rectangular section; two sides are provided with metal splints. The utility model has high-speed performance and higher aerodynamic efficiency, large turning moment, high flexural strength and firm blade fixation.
Description
A kind of 200w wind-force is sent out the machine blade, relates to wind turbines rotor, is specially adapted to the blade structure of 200w wind turbines rotor.
It is mechanical strength and fatigue strength height that the pure glass fibre reinforced plastic material of the most employing of hectowatt hypervelocity wind mill wind wheel blade is at present made its advantage, but owing to all adopt the manual base normal temperature molded curing moulding of sticking with paste, so easily cause the material coefficient of dispersion big, the long skewness of improving quality of exhibition, normal temperature cure deforms the finished product after the depanning easily, cause same wind wheel upper blade shape asymmetric, thereby make the aerodynamic force of wind wheel inconsistent, thereby cause vibration or flutter in the face of waving, this phenomenon is of common occurrence in practice.Adopt the blade of wooden structures in addition in addition, the wooden structures quality is even, and is in light weight.
The utility model purpose is to utilize the advantage of glass fibre reinforced plastics and wooden structures, overcomes its shortcoming, adopts reel and skin glass steel structure thereof, designs a kind of wind wheel blade of the 200w of being only limited to wind-driven generator and its shape and physical dimension have been carried out optimum design.
Accompanying drawing 1 is the utility model plan view;
Accompanying drawing 2 is an accompanying drawing 1A-A sectional drawing;
Accompanying drawing 3 is an accompanying drawing 1B-B sectional drawing;
Accompanying drawing 4 is an accompanying drawing 1C-C sectional drawing;
Now with reference to the accompanying drawings the utility model is described in detail.
The utility model material is the glass fibre reinforced plastic coating on reel and surface thereof.Blade root is adopted the NACA4415 aerofoil profile, blade tip adopts the NACA4412 aerofoil profile, how much strings of a musical instrument are 15 ° by blade root to the blade tip angle, blade root (4) chord length 200mm, blade tip (5) chord length 150mm, 18 ° at blade root peace spiral shell angle, the rectangular cross-section of root connection place 200 * 30mm, metal splint (3) is equipped with in both sides, metal clip is belonged to plate (3) and blade root (4) is fixed on vane arm (2), the wheel hub (1) with bolt.
The utlity model has high speed and higher pneumatic efficiency, moment of rotation is big, bending resistance degree height, and vanes fixed is firm, and this wind wheel starting wind velocity is not higher than 3m/s, and output power is not less than 200w during rated wind speed 7m/s.
Claims (1)
1, a kind of 200w blade of wind-driven generator, constitute by reel and skin glass steel thereof, blade root is adopted the NACA4415 aerofoil profile, blade tip adopts the NACA4412 aerofoil profile, it is characterized in that how much strings of a musical instrument are 15 ° by blade root to the blade tip angle, blade root chord length 200mm, blade tip chord length 150mm, the root connection place is the rectangular cross-section of 200 * 30mm, and metal splint is equipped with in bi-side.
