Abstract
The present invention relates to a water intrusion prevention system (1) mounting on a turbine blade (100) of a wind turbine. In order to exhibit excellent weather protection, the water intrusion prevention system (1) comprises a connecting means (10) adapted for removably fixing the water intrusion prevention system (1) on the turbine blade (100), further a collar sheet (20) disposed on the connecting means (10) and having a collar portion (22) extending away from the connecting means (10), the collar portion (22) constituting an upper collar sealing round about against an outer surface (101) of the turbine blade (100) if the water prevention system (1) is mounted on the turbine blade (100). In addition, the water intrusion prevention system (1) includes an umbrella sheet (30) disposed over the connecting means (10), the umbrella sheet (30) covering an upper side of the pressing means (10) and protruding laterally downwards away from the connecting means (10) round about the turbine blade (100) if the water prevention system (1) is mounted on the turbine blade (100). The umbrella sheet (30) sealingly adjoins the collar portion (22).
