Embodiment Construction

[0020] Please refer to figure 1 and figure 2 as well as image 3 As shown, this embodiment provides a wind power tower anti-strong wind device, including a tower main body 10 and a wind generator 20 installed on the top of the tower main body 10, and a plurality of pulleys are arranged along the tower main body 10. Cables 30, wherein one end of each cable 30 is fixed on the top of the tower main body 10, and the other end of each cable 30 is connected with a gear linkage 40, and the gear linkage 40 is connected with the control system, through the The control system controls the gear linkage device 40 to drive the contraction or expansion of the cable 30. When the cable 30 contracts, the cable 30 hangs down along the tower body 10 and is retracted. The cable When 30 is unfolded, the stay cables 30 pass through the sweep range of the wind turbine 20 blades, and the bottom end of the tower main body 10 is equipped with a plurality of strain measuring devices 50 corresponding ...

Abstract

The invention relates to a strong wind preventing device of a wind power tower. The strong wind preventing device of the wind power tower comprises a tower body and a wind driven generator installed at the top end of the tower body. Multiple inhaul cables are arranged along the tower body. One end of each inhaul cable is fixed to the top end of the tower body, and the other end of each inhaul cable is connected with a gear linkage device. The gear linkage device is connected with a control system. The gear linkage device is controlled by the control system so as to control the inhaul cables to be folded or unfolded. When the inhaul cables are folded, the inhaul cables are hung down and folded along the tower body. When the inhaul cables are unfolded, the inhaul cables penetrate through a blade sweeping area of the wind driven generator. The bottom end of the tower body is provided with multiple strain measuring devices corresponding to the inhaul cables in number. Most of horizontal force caused by strong wind on the wind power tower is transferred into inhaul cables, and the stress level and collapsing probability of the tower are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power towers, in particular to an anti-strong wind device for wind power towers. Background technique [0002] The wind power tower belongs to the tower-mast structure. With the development of wind power technology, the wind blades are getting bigger and bigger, the height of the wind turbine tower is also increasing, and the cost of the corresponding wind turbine is also increasing. Therefore, in order to reduce the average annual power generation cost of large-scale wind turbines, the design life of wind power generation began to increase significantly. In the service of wind turbines, the wind speed corresponding to wind load can be divided into normal wind speed and extreme wind speed. In the normal wind speed, the wind power drives the fan blades to rotate to realize power generation; under normal circumstances, the wind power tower corresponds to the normal wind speed in most of the time, or l...
