Abstract: A capture device for a bore hole of a fluid source, has a base plate (6) that can be anchored at the floor, over the bore hole, and has a bore hole opening (8) through which fluid can be streamed out of the bore hole. An ascending pipe (2) is arranged over the bore hole opening (8). Guide baffles (9) are arranged around the bore hole opening (8), and have blades (10) fixed to the top of the base plate (6) so that the guide baffles (6) can be pivoted and displaced. The blades (10) encompass the longitudinal end (3) of the ascending pipe (2) that faces the bore hole opening (8) like a flower and overlap one another, whereby fluid flowing from the bore hole opening (8) can be captured via the blades (10) and discharged to the ascending pipe (2).
