MOTORIZED FISHWAY SYSTEM USING MONORAIL, FOR MOVING FISHES QUICKLY AND SAFELY REGARDLESS OF TRAVELING WAY OF MOTHER SHIP

摘要

PURPOSE: A motorized fishway system using a monorail is provided to quickly move fishes regardless of the traveling way of a mother ship by making a rail for the motor ship into the monorail and to prevent rails for the mother ship and a catcher boat from being covered with a pile of wastes. CONSTITUTION: A motorized fishway system mounted at water facilities as a dam, a reservoir, and beams to capture and release fishes of the downstream in the upstream is composed of two mother ship stations disposed at the upstream and downstream of the water facilities and positioned at the upside of the surface water; two catcher boat stations installed to contact with the surface water of the downstream of the mother ship station or the surface of the surface water of the upstream and to capture or release the fishes; a mono rail(30) disposed between two mother ship stations and formed with a rack gear(31); a rail for a catcher boat(60) interposed between the mother ship station and the catcher boat station; a mother ship(50) installed at the upside of the mono rail and composed of a pinion gear(80) engaged with the rack gear formed at the bottom side of the mono rail with reciprocating in a region between the mother ship stations and a mother ship-towing motor(90) for driving the pinion gear; the catcher boat placed on a guide rail(100) installed on the mother ship to move along the region between the mother ship stations together with the mother ship; and a fish capture bucket(70) having a capture door(140) disposed at the catcher boat to capture the fishes with moving together with the catcher boat and a release door(150) for releasing the captured fishes. The catcher boat is moved by a towing bobbin(120) rotated between the catcher boat station and the mother ship station out of the region of the mother ship station by a catcher boat towing motor(110) and a wire wound and unwound from the towing bobbin.
