Title: Aquatic organism adhesion prevention device
Inventor: TSUDA SATORU
IPC: E02B1/00
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of aquatic organism. SOLUTION: An aquatic organism adhesion prevention device 1 according to this invention has a streamlining plate 10 regulating a passing passage of a water stream in the vicinity of a water contact wall face of an underwater structure such as an opening type inlet channel. Consequently, the water stream is regulated by the streamlining plate 10 and is concentrated in a clearance 150 between a water stream control member and the water contact wall face to control flow velocity of the water stream when the water stream passes the clearance 150 in the vicinity of the water contact wall face to predetermined flow velocity. For this reason, even if aquatic organism attempts to adhere to the water contact wall face, it is washed away by the water stream, cannot adhere to it, and is returned into water (sea water) in the vicinity, thereby suppressing the adhesion of aquatic organism.
