Problems solved by technology

However, the load of this kind of high tower is complicated, and its load is mainly borne by the cylindrical tower and the single pile.
However, the lateral displacement rigidity of the tower frame and single pile is generally small, so under the action of strong wind and sea waves, the top of such a high tower often has a large horizontal displacement and acceleration, which has a great impact on the normal operation of the unit. , reduce the reliability of the wind power tower system, and may also cause serious damage to the fixed connection structure

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0026] A side-sway resistant wind power tower, such as figure 1 shown, including:

[0027] Tower base, fixed on the ground;

[0028] The wind turbine frame is installed on the tower base and utilizes wind power to generate electricity;

[0029] Also includes:

[0030] The electromagnetic damper 6 is located between the power generator frame and the tower base, and uses electromagnetic energy consumption to reduce the lateral displacement moment that the tower base bears. Wind direction changes are equipped with multiple or one.

[0031] The tower base includes a foundation 1 fixe...

Abstract

The invention relates to an anti-side shift wind power generation tower. The anti-side shift wind power generation tower includes a tower base fixed on a ground surface; a wind power generation rack arranged on the tower base and using wind to generate power; electromagnetic dampers arranged between the wind power generation rack and the tower base, wherein a side shift torque acted on the tower base can be reduced through an electromagnetic energy consumption manner. Compared with the prior art, the electromagnetic dampers are arranged between the wind power generation rack and the tower base, swinging energy of the tower base due to wind force can be reduced through the electromagnetic energy consumption manner, the side shift torque acted on the tower base can be reduced, and a damping effect can be achieved; and the anti-side shift wind power generation tower is easy to produce, is low in maintenance cost, and is high in practicality.

Description

technical field [0001] The present invention relates to a wind power generation equipment, in particular to a side-slip anti-wind power generation tower. Background technique [0002] The wind power tower system is a structure for wind power generation. It is mainly composed of a foundation, a cylindrical tower, a nacelle, a hub, blades, and a unit. The nacelle and other structures are supported by a cylindrical tower, and the cylindrical tower is placed on a separate In the support pile (or other types of foundation), the connection between the engine room and the cylindrical tower, and the connection between the cylindrical tower and the individual support pile are all connected by two-way bolts; because this high tower form has the advantages of simple structure, convenient manufacture and installation, so At present, it has been widely used in the field of wind power generation. However, the load situation of this high tower form is complicated, and its load is mainly b...
