Abstract

The invention discloses a fish-passing device for a water conservancy and hydropower dam. The fish-passing device for the water conservancy and hydropower dam structurally comprises a plate weir, a flow-stabilizing chamber, a fish-passing fishway, a diversion canal, a buffer box and a communicating water pipe. The plate weir is arranged above the side of the flow-stabilizing chamber, the flow-stabilizing chamber is arranged above the fish-passing fishway, the fish-passing fishway is connected with the diversion canal, and the buffer box is arranged above the diversion canal and is connected with the diversion canal through bolts in a strengthening mode. The end at the top of the communicating water pipe is connected with the buffer box, the end on the lower portion of the commutating waterpipe is connected with the lower part of the fish-passing fishway, the position of the buffer box is higher than that of the fish-passing fishway, the fish-passing fishway is provided with a fishwaywater inlet and a controllable fish luring device, and the fishway water inlet is connected with the fish-passing fishway. The fish-passing device for the water conservancy and hydropower dam is provided with the controllable fish luring device to improve the probability of shoal of fish entering the fishway and greatly increase the efficiency of backflow of shoal of fish, the controllable fish luring device is easier to operate and can be placed in water for a long time, and the trouble of repeated lifting to start and stop is reduced.

Description

technical field [0001] The invention is a fish passing device for water conservancy and hydropower dams, belonging to the field of fish passing devices for water conservancy and hydropower dams. Background technique [0002] Foreign countries have gained rich experience in fishway experimental research and practical engineering applications. In particular, the United States began to build fishways in the early 20th century, and built the fishway with the highest water head in the world in the 1950s. Fish migration and river ecological protection provide protection. At present, after the construction of water conservancy projects in Xinjiang, Tibet and other places in my country, they have tried to build fish passage facilities such as fish passages by learning foreign practical experience in fish passage construction. The fish effect is poor; and because people's awareness of environmental protection is not high, there are too many floating objects in the river, which can ea...
