Description

Fish passing device for water conservancy and hydroelectric dams

technical field

The utility model belongs to the field of fish passing equipment, in particular to a fish passing device for water conservancy and hydropower dams.

Background technique

The construction of the dam of water conservancy and hydropower projects has blocked the exchange of fish populations, and the fish passing facility is to restore the exchange of aquatic organisms

It is an important facility, which plays an important role in the upward spawning of fish and the exchange of species. At present, the existing fish passing facilities use fish collection boats, but because the dams of water conservancy and hydropower projects generally only release the ecological flow, the downstream flow is small. The water is shallow, the river surface is narrow, and the riverbed is mostly rocks. Fish collection and transportation boats often cannot operate safely. The downstream mainstream of the tail water is the place where fish are most likely to gather, and the closer to the tail water outlet of the power plant, the more obvious the fish collection effect. , but due to the unstable power generation flow of the power plant, fish collection boats cannot approach the tailwater outlet of the power plant of the dam for fish collection in consideration of safety issues
