Automatic fishing ladder utilizing river water to generate electricity
The invention discloses an automatic fishing ladder utilizing river water to generate electricity. The fish ladder comprises a riverbed, a transmission cavity is formed in the riverbed, the upper side of the transmission cavity is provided with a reverse flow sliding groove with an upward opening in a communicating mode, chain wheel rotating shafts which are symmetrical left and right are rotationally connected between the front wall and the rear wall of the transmission cavity, the chain wheel rotating shaft on the left side is located on the upper side of the chain wheel rotating shaft on the right side, the outer circle faces of the chain wheel rotating shafts are fixedly sleeved with chain wheels, a chain is wound between the left chain wheel and the right chain wheel, and vertically-symmetrical chain fixing blocks are fixedly connected to the end faces of the sides, away from the chain wheel rotating shafts, of the chains correspondingly. By changing the shape of the fish ladder, electric power is provided through hydroelectric power generation equipment, then the fish ladder is driven to flow upwards and be thrown out, and therefore fishes needing to lay eggs and breed can conveniently return to the upstream, the survival rate is increased, meanwhile, assistance is provided for the fishes; and the fish ladder on the upper side can be lifted and the shape of the fish ladder can be changed, and therefore, maintenance personnel can maintain conveniently.
本发明公开的一种利用河水发电的自动鱼梯，包括河床，所述河床内设有传动腔，所述传动腔上侧连通设有开口向上的逆流滑槽，所述传动腔前后两壁之间分别转动连接有左右对称的链轮转轴，左侧所述链轮转轴位于右侧所述链轮转轴上侧，所述链轮转轴外圆面均固定套设有链轮，左右两个所述链轮之间绕设有链条，所述链条远离所述链轮转轴一侧端面分别固定连接有上下对称的链条固定块，本发明通过改变鱼梯的形状的方式，先通过水力发电设备提供电力，再通过带动鱼梯逆流而上并将其抛出，进而便于所需产卵繁殖的鱼类回到上游，提高存活率的同时为鱼类进行助力，同时本装置能将上侧的鱼梯上升并改变其形状，进而便于维修人员进行维修。
