Fastening belt assembly and method for mounting and dismounting wind turbine generator turbulent flow strip

Abstract

The invention discloses a fastening belt assembly and method for mounting and dismounting a wind turbine generator turbulent flow strip. The fastening belt assembly comprises two fastening belts, a fastener, a hook and loop fastener, a mooring rope and a binding belt. The binding belt and the hook and loop fastener are utilized for attaching and fixing the two fastening belts, and therefore the whole fastening belt assembly is stably connected, external force can be applied through the mooring rope to flexibly dismount the fastening belt assembly, and the manufacturing technology of the fastening belt assembly is simple and convenient. The method for mounting and dismounting the wind turbine generator turbulent flow strip specifically comprises the steps that the fastening belt assembly mounted on a wind turbine generator high tower barrel is utilized as a carrier, the turbulent flow strip is mounted on the fastening belt assembly, and mounting of the turbulent flow strip on a wind turbine generator can be achieved; and in the later period, the fastening belt assembly can be separated from the tower barrel only by pulling the mooring rope on the ground, manual dismounting of the turbulent flow strip can be achieved without other auxiliary hoisting, the beneficial effect of convenient dismounting and mounting is achieved, the dismounting cost of the turbulent flow strip is reduced, certain construction risks are avoided, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of installation and disassembly of a spoiler strip on a wind turbine tower, in particular to a fastening belt assembly and method for installing and dismounting a spoiler strip of a wind turbine. Background technique [0002] With the rapid development of the tonnage and height of large mobile cranes, the development of wind turbines has reached the development stage of wind farms with unconventional heights. However, as the height of the tower increases, the vortex-induced vibration of the tower will intensify. The use of operating personnel and units has brought safety hazards, and the risk of tower collapse has followed, restricting the development of the wind power industry.

Problems solved by technology

[0002] With the rapid development of the tonnage and height of large mobile cranes, the development of wind turbines has reached the development stage of wind farms with unconventional heights. However, as the height of the tower increases, the vortex-induced vibration of the tower will intensify. The use of operating personnel and units has brought safety hazards, and the risk of tower collapse has followed, restricting the development of the wind power industry

[0003] At present, the promotion and use of spoiler strip technology on high tower tubes has solved the problem of vortex induced vibration during hoisting of high tower tubes, but the spoiler strips need to be removed before the wind turbine is powered on. There is a certain time period, and at this time the crane and other auxiliary equipment are likely to have been transferred, and the height of the tower using the spoiler is above 110m, it is very difficult to remove the spoiler from the top of the cabin, and there is a big problem.
