AI Technical Summary
Static testing of wind turbine blades requires working at heights to install, adjust, and initialize force sensors, which is inconvenient in inclement weather, affecting testing efficiency and safety.
Design a vertical pull-down static loading test device for wind turbine blades that eliminates the need for climbing. Utilize components such as an electric hoist, tapered boom, pressure plate, and electric push rod to enable the force sensor to be installed and removed without climbing. The device is operated via a wireless remote controller, reducing the risk of cross-operation on site.
Significantly reduce the risks of working at heights, improve testing efficiency, lower costs, adapt to harsh weather conditions, shorten testing cycles, and ensure the timeliness of blades from design to market launch.
