Problems solved by technology

In order to obtain better wind resources, the installed capacity of a single unit and the height of wind power towers are gradually increasing. In this case, the traditional wind power tower structure can no longer meet the structural strength and rigidity requirements under the existing transportation and construction conditions. Requirements, which have adverse effects on power generation efficiency and structural safety

Embodiment Construction

[0023] Referring to the accompanying drawings, a detailed description will be given of the tangent-to-stay cable wind power tower provided by the present invention in combination with an embodiment.

[0024] refer to figure 1 with figure 2 , The structure of the wind power generation tower in this embodiment is provided with two sets of tangent pair stay cables, the two sets of stay cables form a cross, and there are four prestressed stay cables in total.

[0025] The middle part of each prestressed cable 2 is fixed on the tower tube 1 of the wind power generation tower through the bolt node 3, and goes around the tower tube to the opposite direction, and the two ends are fixed on the anchor point 4. Such as image 3 with Figure 4 As shown, the bolt node 3 is located below the impeller of the wind power tower and is arranged on the tower wall 5 , including an upper splint 6 , a lower splint 7 , a pressure plate 9 and bolts 8 . Among them, the thickness of the upper splin...

Abstract

The invention discloses tangent opposite-pull pulling cables and a wind power generation tower using the cables. The middles of the two pre-stressed pulling cables are separately fixed to the positions, below an impeller of the wind power generation tower, of a tower drum in the tangent directions of the two sides of the wall of the tower drum through bolt joints, and the two ends the pulling cables are anchored to the ground. Since the pulling cables do not pass through the center of the tower drum, the pulling force of the pulling cables provides initial torsional rigidity, the fatigue problem of pulling cable joints caused by frequent torsional vibration of the tower drum is solved, and in addition, the bolt joints are connected to the drum wall through anti-shearing bolts, welding connection is avoided, and anti-fatigue performance is improved.

Description

technical field [0001] The invention belongs to the design field of wind power generation towers, and in particular relates to a tangential pair pulling cable structure and a wind power generation tower adopting the cable structure. Background technique [0002] With the development of wind power generation and the limitations of my country's power transmission capacity, my country has gradually begun to develop wind power resources in low wind speed areas. In order to obtain better wind resources, the installed capacity of a single unit and the height of wind power towers are gradually increasing. In this case, the traditional wind power tower structure can no longer meet the structural strength and rigidity requirements under the existing transportation and construction conditions. Requirements have adverse effects on power generation efficiency and structural safety. In order to improve the rigidity and bearing capacity of the traditional wind power tower, it is necessar...
