Problems solved by technology

[0003] At present, it is proposed at home and abroad to induce fish to enter the fishway through measures such as increasing water replenishment methods, lighting to lure fish, and improving fishways. The layout of the plates is prone to small eddies, causing fish to lose their way during migration

Abstract

The invention discloses an intelligent control device for fish migration and an operation method thereof. The device includes a column arranged in a fishway, the outside of the column slides and fits with the inside of an adjustment ring, and the outside of the adjustment ring is rotatably connected with the inside of a rotating ring. The outer side of the rotating ring is fixedly connected with the fish luring rotor, the end of the adjusting ring is connected with one end of the telescopic mechanism, and the other end of the telescopic mechanism is fixed on the inner wall of the fishway, and the end of the rotating ring is connected with the circular rotating shaft of the servo motor through the rotating sleeve side sliding connection; in addition, the invention also discloses the corresponding operation method; the invention can study the fish migration process based on hydrodynamic conditions for different water conditions and different types of fishways, intelligently regulate the water flow in the fishway, and promote The efficiency of fish passing in the fishway can better protect the diversity of flow regime and habitat diversity.

Description

Technical fields: [0001] The present invention belongs to the field of water ecological protection technology, specifically relates to a fish migration intelligent regulation device and its operation method. Background: [0002] Reservoirs have been built in most of the world's large and medium-sized rivers, including some with rich biodiversity. Reservoirs have brought convenience to human production and life in flood control, power generation, irrigation and other aspects, but after the rivers are directly intercepted by the project, it is also difficult for fish in rivers and lakes to achieve traceability and other problems. With the steady advancement of the construction of ecological civilization in recent years, China's water control activities are also focusing on the development of ecological protection, and the fish road as an eco-friendly water conservancy measure to help fish migrate has been continuously valued by people, improving the efficiency of fish crossing and ...
