Problems solved by technology

However, after reaching the dam crest, since there is still a height difference between the dam crest and the water surface, it is necessary to transport the fish to a transport ship on the water surface on the bank, and the fish will be transported to the designated water area by artificial driving. Put the fish into the water, this method of transporting fish is inefficient and labor-intensive

Abstract

The present invention discloses a high-efficiency full-automatic fish lifter system and relates to the technical field of hydraulic and hydroelectric engineering. The fish lifter system comprises a fish collecting subsystem, a fish transporting subsystem and a fish releasing subsystem, the fish collecting subsystem is used for collecting fish, the fish transporting subsystem is used for transporting the fish collected by the fish collecting subsystem to the fish releasing subsystem, and the fish releasing subsystem is used for releasing the fish in the fish transporting subsystem to a water area in front of a dam through a fish unloading groove. Therefore, the fish lifter system can transport the fish from a downstream water area to an upstream water area. The fish lifter system also comprises a centralized control subsystem which is used for monitoring and controlling operation of the fish collecting subsystem, the fish transporting subsystem and the fish releasing subsystem to form ahigh-efficiency and automatic working process, so that efficiency of the fish lifter is improved and labor is also saved.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a fish lifting machine system. Background technique [0002] The current domestic water conservancy and hydropower projects have done a lot of research on the problem of fish migrating across dams. One of the commonly used solutions is to use bionic fishways. The focus of this facility is to simulate ecological river systems, creating a near-natural environment for fish. Migration channels of ecological rivers, so that fish can swim from downstream waters to upstream waters along the migration channels. [0003] However, this is usually only applicable to projects with a small upstream and downstream water level difference. When the upstream and downstream water level difference is large, in order to slow down the water flow, it is necessary to build a very long bionic fishway, which affects the terrain and geology of the project site. The requirements...
