Problems solved by technology

However, this pitch-changing method can only drive one blade to adjust the pitch, so the convenience of pitch-changing is poor. At the same time, multiple sets of pitch-changing mechanisms make the structural size larger. At the same time, the structural form of the ratchet mechanism is adopted, and the reliability is slightly poor. Poor maintenance convenience

Embodiment Construction

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0039] see figure 1 , figure 2 and Figure 4 , a special power adjustment device for fans, including a motor 1, a lead screw 2, an inner screw drive rod 10, a drive gear 4, and an outer peripheral gear 5, the output shaft of the motor 1 is connected to the lead screw 2, and the lead screw 2 is controlled to rotate clockwise or Turn counterclockwise. The screw 2 is covered with an internal screw drive rod 10 , and the rotation and movement of the internal screw drive rod 10 along the axis of the screw 2 is realized through the cooperation of the internal and external threads. The end of the internal helical drive rod 10 is connected to the drive guide rod 3, the other end of the drive guide rod 3 passes through the bracket I6 and is fixedly connected to the drive gear 4, and the outer surface of the drive gear 4 is protruded alon...

Abstract

The invention discloses a special power adjusting device for a fan. The special power adjusting device for the fan comprises a power mechanism for outputting rotary motion, a driving guide rod (3) used for converting the rotary motion into linear motion, and a transmission mechanism used for converting the linear motion into turning motion, wherein the power mechanism is fixedly connected with thedriving guide rod (3), the driving guide rod (3) is controlled to move linearly in the axis direction of the power mechanism; the other end of the driving guide rod (3) penetrates after through a support I (6) and then is fixedly connected with the transmission mechanism; and the transmission mechanism is installed on the support I (6) through supports II (7), a plurality of blades (8) are installed on the supports II (7), and all the blades (8) are synchronously rotated under the coordination of the power mechanism and the transmission mechanism, According to the special power adjusting device for the fan, the included angle between the blades and the horizontal direction is changed, then the wind receiving area of the fan blades under different conditions is changed, and the obvious effect of power regulation is achieved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation equipment, and in particular relates to a special power adjustment device for large and medium-sized wind power generators. Background technique [0002] Wind energy resources are very rich in the world, and almost all regions and countries have considerable wind energy reserves. In recent years, energy issues have become a focus of widespread concern in various countries. The storage capacity of coal resources and oil resources can only meet hundreds of years of exploitation. At the same time, environmental issues have also become an important problem that plagues the country and society. Turn your attention to the development and utilization of new energy. As one of the important components of renewable energy, wind energy has attracted widespread attention from researchers and has also received strong support from governments of various countries. [0003] The current developmen...
