Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which the same reference numerals are used for the same components.

[0035] figure 1 is a schematic diagram showing an existing spoiler block installed on a tower section. like figure 1 As shown, the cross-section of the existing spoiler block 100 is usually triangular, and the cross-section of some spoiler blocks 100 is circular, and the cross-sectional area is usually 400-500mm 2, if the diameter of the tower section 400 exceeds 7 m, the size of the spoiler 100 needs to be further increased in order to have the effect of suppressing the vortex-induced vibration. Please be aware of, figure 1 The helically wound spoiler block 100 in is actually formed by connecting a plurality of spoiler blocks.

[0036] figure 2 is a schematic diagram illustrating a spoiler block in an unused state according to an embodiment of the present invention. im...

Abstract

The present invention provides a spoiler block and a vortex-induced vibration suppression device. The spoiler block includes: a deformation part, the deformation part includes a windward surface, and an air hole is provided on the windward surface; and an airbag is provided on the airbag. Inside the deformation part, wherein the air bag is communicated with the air hole, so that the airflow entering through the air hole can enter the air bag and inflate the air bag, so that the deformation part is deformed from the flat first state to the expansion the second state. Compared with the non-deformable spoiler block of the same size in the prior art, the spoiler block in the flat first state of the present invention can significantly reduce the transportation volume of the tower, and reduce the transportation risk and the risk of bumping during transportation, And the spoiler block provided by the present invention can change the usage state by the wind power.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more particularly, to a spoiler block and a vortex-induced vibration suppression device. Background technique [0002] With the continuous development of offshore wind power generation technology, the current new trend is to use tower structures such as large diameters and high towers to meet the development needs of offshore large-megawatt wind turbines. Vortex-induced vibration of the rack occurs frequently. From the perspective of fluid, any non-streamlined object will alternately generate vortices detaching from the surface of the structure on both sides of the object at a constant flow rate. Cyclic pulsating pressure. If the column is elastically supported at this time, or the flexible pipe body is allowed to undergo elastic deformation, then the pulsating fluid force will cause periodic vibration of the column body (the pipe body), and this regular column vibration will ...
