Problems solved by technology

[0002] At present, the wind rotor of the known small and medium-sized wind turbines is composed of three blades, and the ends of the blades are not treated, and the airfoil ends naturally. When the blades of this structure are running at high speed, the airflow is easy to flow at the blade ends. At this time, the vortex has a certain amount of energy, which is released through noise, thus forming noise pollution, which makes this kind of wind turbine not suitable for installation in residential areas or living areas.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] like figure 1 As shown, a blade of a wind power generator includes a blade body 1, a rectangular end wing 2 and a transition section 3 between the blade body 1 and the end wing 2, wherein the length of the end wing is the length of the blade body at the transition 2 to 4 times the width a of the end portion on one side of the segment, and the width of the end flap is 0.5 to 1 times the length of the end flap. exist figure 2 image 3 It can be seen in the illustrated embodiment that the transition section 3 is a rounded transition section.

[0019] from figure 1 , figure 2 , image 3 It can be seen that the end wing has a first airfoil 201 along the rectangular length direction and a second airfoil 202 along the rectangular width direction, the first airfoil 201 extends along the width direction of the blade body 1, and the The leading edge and the trailin...

Abstract

The invention relates to a wind driven generator blade which comprises a blade body and further comprises a rectangular end wing and a transition section located between the blade body and the end wing. The length of the end wing is 2-4 times of the width of the end, located on the side, with the transition section, of the blade body, and the width of the end wing is 0.5-1 time of the length of the end wing. The wind driven generator blade is applied to a wind driven generator, vortexes cannot be formed so that noise can be avoided, due to the fact that the rotating speed of the blade is high when the blade rotates, the end wings of three blades can approximately form a circular ring which is in a horn mouth shape, and therefore an acceleration function can be achieved on blown airflow. Thus, the blade efficiency is improved, and the power output of the wind driven generator is increased.

Description

Technical field [0001] The present invention involves a wind turbine equipment, and it is more specifically involved in a blade of a wind turbine. Background technique [0002] At present, the wind wheel of the small and medium -sized wind turbine of the public is composed of three blades. The blade end is not processed. It is naturally ended by the wing type. This kind of structure of the structure is easy to run at the high -speed operation of the wind generator.The ministry forms a vortex. At this time, the vortex has a certain energy. The energy is released by noise to form noise pollution. This makes this type of wind generator not be installed in a residential area or living area. Invention content [0003] In order to overcome the above problems existing in existing technology, the present invention provides a new type of wind generator blade. The technical solution it uses is: a blade of the wind generator, including the blade, also includes the rectangular wings, an...
