Description

Technical Field

[0001] The invention belongs to the technical field of wind turbines, and in particular relates to a device for laying glass fiber cloth for the outer covering of a wind turbine blade. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind rotor, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device.

[0003] Rotor blades are one of the important components of wind turbines. They can capture wind and transmit wind power to the rotor axis. When producing blades, one of the procedures is to lay the outer skin fiberglass cloth on the blade mold. Generally, a crane is used to assist in lifting the fiberglass cloth so that the fiberglass cloth is suspended above the mold. At this time, manual support and dragging of the wound fiberglass cloth is required to move radially along the mold. During this process, the fiberglass cloth laid on the mold is prone to wrinkles, and a large amount of manpower is required to flatten the fiberglass cloth later. Due to the large number of layings, the production efficiency of the entire blade will be reduced, which greatly occupies manpower. Summary of the invention
