In this case, by providing an air filter at the outlet 5 of the air collecting unit 2 of the air collecting device 1 to collect moisture, drinking water can be produced on an island with little rain water. Furthermore, the power of the typhoon can be weakened by removing moisture from the wind.
  • the relatively heavy wind power generation unit assembly 60 is provided on the ground after being provided at the lower part on the back side of the wind collecting device 1, the wind collecting device 1 can be stably installed, and wind power generation is also possible. Maintenance of the wind turbine generator 30 in the unit 61 can be easily performed.
  • the wind power generation equipment is installed on a rotary table that can be rotated by a drive source such as a motor, and the power generated by the wind power generator 30 is supplied to the drive source so that the wind power generation equipment can be rotated around the vertical axis by the rotary table.
  • the rotation angle may be controllable. Accordingly, the wind power generation facility can be controlled to rotate so that the front surface of the wind collecting device 1 is directed in the direction in which the wind blows, so that power can be generated efficiently.

Abstract

Appareil de collecte de vent dont la taille peut être facilement augmentée et qui peut collecter et éjecter efficacement le vent. L'appareil de collecte de vent est équipé d'une partie de collecte de vent 2 pour collecter, au niveau d'une ouverture d'éjection 5 située sur le côté face arrière, le vent qui a été pris à partir du côté face avant. L'ouverture d'éjection 5 se situe plus bas que l'extrémité supérieure de la face avant de la partie de collecte de vent 2. Dans la partie de collecte de vent 2, la taille de superficie en coupe transversale de chemin d'écoulement diminue depuis le côté face avant vers le côté face arrière. La partie de collecte de vent 2 est pourvue d'une partie paroi en demi-cône 3. Une pluralité de montants de support 10 sont disposés de manière à pénétrer dans la partie paroi en demi-cône 3. Les extrémités supérieures des montants de support 10 et de la partie paroi en demi-cône 3 sont reliées par des câbles 12, et la partie paroi en demi-cône 3 est suspendue par les câbles 12. Ainsi, la taille de cet appareil de collecte de vent peut être facilement augmentée et cet appareil peut collecter et éjecter efficacement le vent.
