The present invention proposes a lightning protection device of a windmill blade, comprising a tip receptor assembly having receptors which are mounted, in particular to, the tip end part of the blade where the blade profile becomes smaller, and having a simple structure so as to be readily assembled, and an intermediate receptor assembly having a receptor which is set at the outer surface of the blade so as to exhibit an effective countermeasure against increasing of the air pressure in the blade upon a lightning striking upon the blade, a lightening current being discharged to the ground from the receptors through connection equipment such as lead wires laid through the inside of the blade the windmill body and bypass brushes, characterized in that a base plate made of an electrically conductive material and connected thereto with the lead wires is embedded in the blade, and the receptors are secured and supported to the base plate, being exposed at the outer surface of the blade. Further, the present invention also proposes a method of assembling the lightning protection device.

La présente invention concerne un dispositif parafoudre d'une pale d'éolienne comprenant un récepteur, à fixer à l'extrémité pointue d'une pale où un profil de pale possède une taille particulièrement réduite, et alliant simplicité de structure et facilité d'assemblage. Ledit récepteur de foudroiement est installé sur la surface d'une pale afin d'agir efficacement contre un accroissement de pression se produisant dans une pale lorsque la foudre frappe la pale. Le courant de foudre provenant du récepteur fait l'objet d'une mise à la terre via un fil conducteur traversant l'intérieur de la pale et du corps d'éolienne ou via un organe de liaison tel qu'un balai de dérivation. Le dispositif se caractérise en ce qu'une plaque de connexion consistant en un conducteur auquel est relié le fil conducteur est encastrée dans la pale, un ensemble récepteur formé par fixation du récepteur à la plaque de connexion reposant sur la pale et faisant face à sa surface. L'invention concerne également un procédé d'assemblage du dispositif parafoudre.
