Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blades, in particular to a turning device for installing wind turbine blades. Background Art

[0002] The main function of wind turbine blades is to convert natural wind energy into electrical energy for wind turbines. Wind turbine blades are the core components of wind turbines that convert wind energy into electrical energy. These blades are usually made of composite materials and have a thin shell structure to improve their mechanical properties and durability. The shape and size of the blades are designed to maximize the capture of wind energy and convert it into mechanical energy, which is then converted into electrical energy through a generator and ultimately provides electricity to the grid system. For small wind turbines, the generator blades are generally handmade of metal or fiberglass, among which fiberglass blades are the most popular and practical blades.

[0003] After searching, the patent document with publication number: CN220761729U discloses a device for adjusting the installation angle of wind turbine blades; it drives the pressure plate on the placement table by the second cylinder to press and fix the wind turbine blades up and down, and drives the clamping block by the first cylinder to fix the wind turbine blades left and right, so as to ensure the fixing effect of the wind turbine blades and prevent the wind turbine blades from sliding and falling when rotating. By setting elastic pads on the placement table, the pressure plate and the clamping block, damage to the wind turbine blades can be effectively avoided. The movable plate is pushed to move by the electric push rod, and the adjustment table is rotated by the rack on the movable plate and the adjustment tooth, so as to adjust the angle of the wind turbine blades and adjust the wind turbine blades to a suitable angle for installation. Although the above device has solved some existing problems, in actual use, when the wind turbine blades need to be turned over, the placement table cannot be turned up and down, and the position needs to be readjusted during installation.
