Specific method for the complete cleaning and restoration of wind-turbine blades impregnated with hydraulic fluid from the machinery of the wind turbine. The different stages of the method remove the hydraulic fluid both from the accessible parts of the blade and the internal parts of the blade, i.e. inside the shells (4), spaces between the leading edges (6) and trailing edges (5) and the beam (3) and the beam (3)/shell (4) joint area. To achieve this, several holes (7) are drilled, in a specific order and at defined points of the blade, into which a cleaning fluid is subsequently injected at high pressure in the accessible areas, and pulverized in the case of the areas inside the blade, which makes it possible to remove the hydraulic fluid and thereby restore the blade once all traces of hydraulic fluid have been removed. |
