摘要

PURPOSE: a kind of fish Transmission system dam is provided to be automatically moved fish by control water level, even if installing the system on vertical surface or inclined-plane using the net of longitudinal movement. ;CONSTITUTION: a kind of fish Transmission system dam includes upper passage (3) using the net of longitudinal movement, lower guideway channel (10), hydraulic pressure open-close sluice gate (4), net (5), lamp (13). The upper and lower guide channel allows to connect work and enters upstream and downstream. Hydraulic pressure open-close sluice gate is formed in upper and lower guide channel and mobile channel (1), and the channel that fish are mobile by control water level. The net transfer volume fish pass through moving up and down for mobile movable passageway. By illuminating lamp tube fish in mobile channel. ;The 2010 of copyright KIPO submissions
