Embodiment Construction

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] The technical solution of the present invention is to bind to the pneumatic characteristics of the blade, and the blade spoiler is designed, and the blade disturbance flow device is mounted on the blade, and the blade before operating the rear unit is restored.

[0028] like figure 1 As shown, the present invention provides a wind-moving blade intercharacter, including a blade spoiler body 2, a fixed wind rope 4, and a wind rope 5, which are arranged in the impeller blade 1 tip, wherein the blade spoiler body 2 has a rule. Or irregular protrusions, the blade spoiler body 2 is used to form a regular or irregular protrusion surface on the surface of the impeller blade, preventing the surface of the impeller blade 1 to form a certain direction or regular pneumatic excitation, the blade spoiler body 2 is away from One end of the impeller blade 1 i...

Abstract

The invention discloses a wind power blade turbulence device and method. The wind power blade turbulence device comprises a blade turbulence device body arranged on an impeller blade in a sleeve mode, a fixing wind rope used for fixing the blade turbulence device body to the impeller blade and a wind cable used for disassembling the blade turbulence device body, the blade turbulence device body is in a regular or irregular protruding shape, the end, away from the tip end of the impeller blade, of the blade turbulence device body is connected to one end of a fixing wind rope and one end of a wind cable, the other end of the fixing wind rope is connected to the root of the impeller blade or an impeller hub, the other end of the wind cable extends out of one end, close to the tip end of the impeller blade, of the blade turbulence device body and is fixed to the ground. According to the wind power blade turbulence device, the problem of blade vibration in an impeller static state during the period from the completion of fan hoisting to the operation is solved, the problems of bolt looseness of the whole machine connecting part caused by the blade vibration and fatigue load increase caused by the blade vibration are avoided, the safety is improved, and the service life of the impeller blade is prolonged.

Description

Technical field [0001] The present invention belongs to the technical field of wind power blades, and is specifically belonging to a wind-moving blade interference flow device and method. Background technique [0002] In order to actively address the huge challenges of global climate change, it is expected that renewable energy such as wind power, photovoltaic, will gradually develop from supplementary energy into mainstream energy sources. With the advent of the parity wind power, high-quality wind energy resources and development areas gradually decrease. To this end, the single-machine capacity of the wind turbine is getting larger, and the capacity of the land unit has reached 5MW, and the length of the blade reaches 80 meters. . As the length of the blade increases, the flexibility of the blade is increasing. During the actual installation of the fan, especially the impeller is in a static state, which is very easy to show the vibration of the blade, and the blade vibration ...
