Large-scale superposable self-control sailboard type vertical axis wind power device

Abstract

The invention discloses a large-scale superposable self-control sailboard type vertical axis wind power device. The device comprises a vertical power shaft and more than two sailboard groups, whereineach sailboard group comprises a sailboard and a sailboard bearing device thereof; the sailboard consists of more than two window frames; the upper edge of each window frame is movably connected withan air door; the air door can be automatically opened or closed according to the wind direction; the sailboard is connected with the vertical power shaft through the sailboard bearing device so that the vertical power shaft rotates; the sailboard bearing device comprises a support frame and a connecting rod; the sailboard is vertically fixed on the support frame; the support frame is connected with the vertical power shaft through the connecting rod; and the bottom of the support frame is provided with walking wheels. The sailboard of the wind power device has the advantages that the control is easy; the service life is long; the wind resistance is small; the efficiency is high; and the wind power device can adapt to large-scale wind power equipment such as large-scale wind power generation equipment and the like.

Description

technical field [0001] The invention relates to a wind power device, in particular to a large-scale stackable self-control sailboard type vertical axis wind power device. Background technique [0002] Wind power is an earlier power used by humans, which can be used to pump water, generate electricity, etc. The wind power devices used are such as early windmills and current wind power generation devices. [0003] Existing wind power devices mainly include horizontal axis type and vertical axis type. [0004] The horizontal axis wind power device has the disadvantages that the longer the arm is, the easier it is to be blown by the wind and the slower the rotation speed. In addition, the wind receiving surface is limited and the torque output depends entirely on the frame shaft suspended in the air, so it cannot balance high torque and fast speed. . [0005] The vertical axis wind power device has obvious advantages, such as not being restricted by the wind direction, no nee...

AI Technical Summary

Problems solved by technology

However, there are also problems: the area of ​​the blade (sailboard) is too large, it is difficult to control, the inertia is large, and it is easy to be damaged; when the blade is opened, the wind resistance is large and the efficiency is low
