Fishway temperature rise fish leading method

Abstract

The invention discloses a fishway temperature rise fish leading method including the steps that S1, a flow control valve is opened, and hot water coming from a hot water source flows into a water injection pipe; S2, after the water injection pipe is full filled with the hot water, under the effect of water pressure, the hot water enters a gear-like water injection cavity through a water injectionbranch pipe; S3, under driving of an external motor, a gear-like water injection cavity used as a driving wheel drives a gear-like water injection cavity used as a driven wheel to rotate through a chain, and along with rotation of the gear-like water injection cavities, the angles between eccentric water injection holes in the gear-like water injection cavities and the vertical direction unceasingly change, the hot water injected in the corresponding gear-like water injection cavity is supplied into a fishway through the water injection holes, and therefore the water flow temperature in the fishway is evenly raised; S4, a temperature sensor in the fishway and a temperature sensor in a riverway sense the raised temperature in the fishway and the non-raised temperature in the riverway correspondingly; and S5, an intelligent temperature control system controls a hot water passageway of the flow control valve to be opened or closed according to the temperature rise range of the fishway.

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
