Embodiment Construction

[0041] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0043] Such as Figure 1-Figure 3 As shown, this embodiment provides a vibration suppressing device, including a frame body 1 and a pendulum mechanism.

[0044]The frame body 1 is fixedly installed in the tower frame 20 of the wind power generating set;

[0045] The pendulum mechanism is suspended on the fr...

Abstract

The invention provides an anti-vibration device and a tower device of a wind turbine generator system. The anti-vibration device comprises a frame body and a pendulum mass mechanism. The frame body isfixedly arranged on a structure to be suppressed to vibrate. The pendulum mass mechanism is hung on the frame body, and the pendulum mass comprises multistage swing arms and a mass block. The ends ofthe multistage swing arms are connected with each other in a pendular mode. The mass block is arranged on the last stage swing arm. According to the anti-vibration device and the tower device of thewind turbine generator system, when the wind turbine generator system vibrating with own low frequency, length of the swing arms are reduced and the problem that long swing arms causing installation space in the tower in the vertical direction limited is overcome. Meanwhile, adjustment of vibration frequency of the pendulum mass mechanism is convenient.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a vibration suppressing device and a tower device of a wind power generating set. Background technique [0002] With the increasingly fierce competition in the wind power market, increasing the power generation of wind turbines and reducing unit costs have become the two major themes of product competitiveness. Based on this background and challenges, wind turbine towers and soft towers have become more popular and competitive product types in the market. To put it simply, increasing the height of the tower can obtain better wind resources, which can further increase the power generation; the use of flexible towers can further reduce the weight of the tower, thereby reducing the overall cost of the unit. However, high towers and soft towers have product particularities. For example, the vibration problem of the unit in a certain wind speed range is more prominent t...
