Intelligent fish migration regulation and control device and operation method thereof

Abstract

The invention discloses an intelligent fish migration regulation and control device and an operation method thereof. The device comprises a stand column arranged in a fishway, the outer side of the stand column is in sliding fit with the inner side of an adjusting ring, the outer side of the adjusting ring is rotationally connected with the inner side of a rotating ring, the outer side of the rotating ring is fixedly connected with a fish luring rotor wing, the end of the adjusting ring is connected with one end of a telescopic mechanism, the other end of the telescopic mechanism is fixed to the inner wall of the fishway, and the end of the rotating ring is slidably connected with the lower side of an annular rotating shaft of a servo motor through a rotating sleeve. In addition, the invention further discloses the corresponding operation method. According to different incoming water working conditions and different types of fishways, the fish migration process based on the hydrodynamic condition can be researched, the water flow in the fishway is intelligently regulated and controlled, the fish passing efficiency in the fishway is improved, and the flow state diversity and the habitat diversity are better protected.

Description

Technical field: [0001] The invention belongs to the technical field of water ecological protection, and in particular relates to an intelligent control device for fish migration and an operating method thereof. Background technique: [0002] Reservoirs have been built on most of the world's large and medium-sized rivers, including some rich in biodiversity. Reservoirs have brought convenience to human production and life in terms of flood control, power generation, and irrigation. However, after the river is directly intercepted by the project, it also makes it difficult for fish in rivers and lakes to travel back. With the steady advancement of the construction of ecological civilization in recent years, my country's water control activities are also developing in the direction of ecological protection. Fishways, as an eco-friendly water conservancy measure to help fish migrate, are constantly being valued by people. Fish passing efficiency and good ecological environment ...

AI Technical Summary

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
