A DEVICE COMPRISING AN ELONGATED TUBULAR BODY ARRANGED TO BE LOCATED IN WATER

摘要

The invention relates to a device (1), comprising an elongated tubular body (3) arranged to be located in water in an essentially vertical position. The tubular body (3) comprises at the bottom an open end (6) and at the top a narrowing portion (7), which ends in an opening (8) arranged to be located above the level of the surrounding water (2). The device (1) is arranged to establish a water level in the narrowing portion (7) of the tubular body (3), which is lower than the level of the surrounding water and to level out intermittently this level difference in such a way that the water in the tubular body (3) by means of the narrowing portion (7) is transported up to higher level than the level of the surrounding water (2).
