Embodiment 1

[0029] Such as Figure 4-8 As shown, the front slightly winglet of the wind turbine wind turbine cowl of the present invention is characterized in that: the winglet cowl comprising a plurality of winglets and the fixed winglet, the front end of the winglet cowl is an arc surface, and the winglet cowl The rear end has a connecting portion connected with the blade fairing at the position of the blade of the wind turbine, and a plurality of winglets are evenly distributed around the front-rear central axis of the winglet fairing.

[0030] The number of winglets is the same as the number of blades of the wind turbine to be matched. Such as figure 1 As shown, in this way, any winglet is located between two adjacent blades. The winglets guide the wind to the leading edge of the blades of the wind turbine.

[0031] Such as image 3 As shown, in order to fix the winglets in front of the wind turbine shroud on the wind turbine set, a connecting bracket is provided in the inner cavi...

Embodiment 2

[0034] The present invention is a wind generator set with small wings in front of the wind deflector. A plurality of small wings are uniformly arranged on the wind deflector at the position in front of the blades. The small wings can rotate together with the blades and can guide the airflow blown to the small wings Flow to the leading edge of the wind turbine blade behind the winglet.

[0035] The length of the winglet is greater than the length of the cylindrical part of the blade root of the wind turbine blade.

[0036] The number of winglets is the same as the number of blades, and any winglet is located between two adjacent blades.

Abstract

The invention discloses a fairing front winglet of a wind turbine generator and the wind turbine generator with the winglet. The fairing front winglet of the wind turbine generator comprises multiple winglets and a winglet fairing for fixing the winglets; the front end of the winglet fairing is an arc surface; a connecting part connected with a blade fairing in a blade position of the wind turbine generator is arranged at the back end of the winglet fairing; and the multiple winglets are uniformly distributed around front and back central axis of the winglet fairing. The wind turbine generator with the fairing front winglet is uniformly provided with multiple winglets on the fairing in front of blades; and the winglets rotate with the blades, and can guide air currents blown to the winglets to the front edges of the blades of the wind turbine generator behind the winglets. Through arrangement of the winglets, the winglets can make up the defect of cylindrical parts of the blades of the wind turbine generator at the blade root parts incapable of rotating by dint of wind power or weaker rotating efficiency, so that the power generation efficiency of the wind turbine generator is improved.

Description

technical field [0001] The invention relates to a winglet and a wind turbine with the winglet, in particular to a winglet at the front of a wind turbine shroud and a wind turbine with the winglet, belonging to the field of wind power generation devices. Background technique [0002] For the blades of wind turbines, in order to meet the strength requirements and the stability of the connection, the part of the blade near the root of the blade is cylindrical. This part cannot be rotated by the wind or the rotation efficiency is low, which affects the power generation efficiency of the entire unit. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a small front winglet of the wind turbine wind turbine windshield and a wind turbine set with the winglet, which can improve the power generation efficiency of the wi...
