AI Technical Summary
The existing wind turbine blade beam grouting device uses an integral and indiscriminate grouting method, which leads to uneven resin impregnation in different materials, forming dry areas, affecting product quality and increasing production costs.
A closed-loop control system combining a resin distribution pipeline system and electromagnetic control valves is adopted. The system monitors and independently controls the grouting status of each area through infrared temperature sensors, achieving automated, zoned, and on-demand precise grouting.
It completely solved the problem of uneven wetting, improved product quality, reduced production costs, and reduced the use of auxiliary materials and labor costs.
