Fishway inlet fish luring device
The fishway inlet fish luring device comprises two wing walls which are fixedly arranged in a river channel and used for forming a fishway, a fixing plate is arranged at the fishway inlet of the two wing walls, a frame is fixed to one wing wall, a plurality of rotating columns are rotationally connected to the inner side of the frame, front plates are arranged outside the rotating columns, and inner shafts are rotationally connected to the interiors of the rotating columns; pressing plates are fixed to the two sides of the inner shaft, a plurality of sets of open holes are formed in the inner side of the rotating column, a plurality of sets of sliding columns matched with the open holes are fixed to the two sides of the pressing plates, and second springs are further arranged on the portions, between the open holes and the pressing plates, of the outer sides of the sliding columns in a sleeving mode. A first rack is slidably connected to the top of the frame, and insections meshed with the first rack are arranged at the top end of the outer side of the inner shaft. An extrusion cylinder is arranged on the side, close to the frame, of the fixing plate, a first spring is arranged in the extrusion cylinder, the interior of the extrusion cylinder communicates with one end of a pipeline, and one end of a first rack is in sliding fit with the inner wall of the other end of the pipeline through a piston; the invention provides a water flow velocity in a stable interval for the fishway inlet.
本发明公开一种鱼道进口诱鱼装置，包括固定设于河道中的用于形成鱼道的两面翼墙，两面翼墙的鱼道入口处设有固定板，其中一面翼墙处固定有框架，框架的内侧转动连接有多个转柱，转柱外部设有前板，转柱内部转动连接有内轴，内轴的两侧固定有压板，转柱内侧设置有若干组开孔，压板的两侧皆固定有若干组与开孔配合的滑柱，且滑柱外侧位于开孔与压板之间还套设有第二弹簧，框架顶部滑动连接有第一齿条，内轴外侧顶端设置有与第一齿条相互啮合的齿纹，固定板靠近框架的一侧设置有挤压筒，挤压筒内部设置有第一弹簧，挤压筒内部与管道一端连通，第一齿条一端通过活塞与管道另一端内壁滑动配合；本发明为鱼道进口提供一个稳定区间的水流流速。
