Abstract

A system for manufacturing a tower structure of a wind turbine includes an additive printing device having a central frame structure with a platform and an arm member. The arm member is generally parallel to a longitudinal axis of the tower structure. The additive printing device also includes a plurality of robotic arms secured to the arm member of the central frame structure. Each of the robotic arms includes a printer head for additively printing one or more materials. The additive printing device further includes at least one nozzle configured for dispensing a cementitious material. Moreover, the system includes one or more molds additively printed via the additive printing device of a polymer material. As such, the mold(s) define inner and outer wall limits of the tower structure. After the mold(s) are printed and solidified, at least one of the printer heads or the nozzle of the additive printing device is configured to dispense the cementitious material between the inner and outer wall limits of the tower structure.

Description

technical field [0001] The present disclosure relates generally to wind turbine towers, and more particularly to systems and methods for fabricating wind turbine tower structures using a multi-head printer that allows simultaneous printing of tower reinforcements along with concrete to produce complete structures on site. assembly. Background technique [0002] Wind power is considered to be one of the cleanest, most environmentally friendly energy sources currently available, and wind turbines are gaining increasing attention in this regard. A modern wind turbine typically includes a tower, generator, gearbox, nacelle, and one or more rotor blades. The rotor blades use known airfoil principles to capture the kinetic energy of the wind. The rotor blades transmit kinetic energy in the form of rotational energy to turn a shaft that couples the rotor blades to a gearbox (or directly to a generator if a gearbox is not used). The generator then converts the mechanical energy i...
