Method of lure fish with temperature rise in fishway

Abstract

The invention discloses a method for attracting fish by raising the temperature of a fishway, comprising the steps of: S1: opening a flow control valve, and flowing hot water from a hot water source into a water injection pipe; S2: after the water injection pipe is filled with hot water, under the action of water pressure , hot water enters into the gear-like water injection chamber through the water injection branch pipe; S3: Driven by the external motor, the gear-like water injection chamber as the driving wheel drives the gear-like water injection chamber as the driven wheel to rotate through the chain, and the gear-like water injection chamber as the driven wheel rotates. With the rotation of the water injection chamber, the angle between the eccentric water injection hole on the gear-like water injection chamber and the vertical direction is constantly changing, and the hot water injected in the gear-like water injection chamber is supplied to the fishway through the water injection hole, thereby realizing the temperature of the water flow in the fishway. Uniform temperature rise; S4: The temperature sensor in the fishway and the temperature sensor in the river respectively sense the raised temperature in the fishway and the unincreased temperature in the river; S5: The intelligent temperature control system controls the flow rate according to the temperature rise range of the fishway. The opening or closing of the hot water channel of the control valve.

Description

technical field [0001] The invention relates to the fields of water conservancy and hydropower engineering and the ecological environment, in particular to a fish-passing building, and more particularly to a method for attracting fish by raising the temperature of the fishway. Background technique [0002] Fishway is an engineering measure to help fish go up. Building dams and other water conservancy projects on rivers cuts off the way for fish to migrate and spawn. By building fishways, fish can go up during the migration season, thereby Maintain the ecological balance of the river section. [0003] Fishway is a special facility to help fish pass through barriers such as dams smoothly, and plays an irreplaceable role in maintaining the continuity of rivers and the communication of biological populations. The success of fishway structures is one of the evaluation indicators for the health of the river ecosystem, and it is also an important evaluation indicator for ecologica...

Problems solved by technology

[0012] The technical problem to be solved by the present invention is to provide an innovative fishway temperature-raising fish-leading method, which overcomes the shortcomings of the existing fish-leading devices, such as low fish-leading efficiency and high operating costs, so as to guide migratory fish to the entrance of the fishway and improve the quality of fish. The efficiency of passing fish, maintaining the continuity of the river and the exchange of biological populations
