The invention discloses a novel fish ladder. The novel fish ladder comprises a bottom plate and a reversed-U-shaped long groove body defined by side plates at the front end and the rear end, wherein partition plates which are uniformly distributed are arranged in a square long groove in the reversed-U-shaped long groove body in the left-right length direction, and overflow openings are formed in the top ends of the partition plates. The novel fish ladder is mainly characterized in that arc-shaped grooves are formed in the positions, below the partition plates, of the bottom plate, and the lower ends of the partition plates are arranged to be semi-cylinders; the included angle a between the left-right length direction of the bottom plate and the horizontal plane is set to be 30 degrees, and in every two adjacent partition plates, the top end of the next partition plate and the bottom end of the previous partition plate are located on the same horizontal plane. The novel fish ladder has the beneficial effects that the improved fish ladder overcomes the defects in the prior art, river-tracing migratory fishes can penetrate through the partition plates without continuously jumping upwards, and the whole river-tracing migration spawning process is easily completed.
本发明公开了一种新型鱼梯。包括由底板和前、后两端的边板围合成的“”形长槽槽体，“”形长槽槽体上的方形长槽内沿左右长度方向设有均布的隔板，隔板的顶端设有溢流口；本发明的主要特点是：底板位于隔板的下方设有弧形凹槽，隔板的下端设为半圆柱；底板的左右长度方向与水平面之间的夹角a设为30°，相邻两块隔板中，下一块隔板的顶端与上一块隔板的底端在同一水平面上。本发明的有益效果是：改进后的鱼梯克服了现有技术的不足，溯河洄游性鱼类无需连续不断地向上跃起即可穿过隔板，轻松完成整个溯河洄游产卵历程。
