<p>PURPOSE:To increase the power to pump up fishes for promoting the fish-conveying capacity by connecting a branching mechanism on the midway of a discharge pipe to regulate the discharge inside the discharge pipe properly. CONSTITUTION:A branching mechanism 9 is provided on the midway of a discharge pipe 7 for regulating the discharge inside the discharge pipe properly. When a pump 5 is driven, water in a fish farm 1 and fishes 3 are sucked into a suction pipe 6, and discharged to the second fish farm 4 through the discharge pipe 7. At this stage, a regulation valve 12 of the branching mechanism 9 is properly regulated to adjust the discharge inside the discharge pipe 7 in the minimum level necessary. This construction serves to reduce the flow resistance inside the discharge pipe 7 and the whole distance of pumping up. Thus, the pumping-up force of fishes 3 is greatly increased for promoting the fish-conveying capacity.</p> |
