Embodiment Construction

[0044] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the present invention will be further described in detail through and specific implementation.

[0045] The fish-passing type ship lock of the present invention uses the ship lock itself as the communication channel of the upstream and downstream water bodies, and passes fish while the ship passes the dam.

[0046] From June 2009 to March 2012, the Chinese Sturgeon Research Institute conducted surveys and statistics on all fish found in the ship locks during the maintenance of the Three Gorges Ship Lock and the Gezhouba Ship Lock. Fish resource surveys were carried out in the waters between the dams.

[0047] 11 species of fish were collected during the survey of the 3 lock chambers of the ship lock on the south line of the Three Gorges, nam...

Abstract

The invention discloses a fish-passing type lock and a fish-passing method. The fish-passing type lock comprises a fish collecting and water replenishing gallery system with the inlet end located in an upstream approach channel and the outlet end located in a downstream approach channel, a fish luring and water replenishing gallery system with the inlet end located in the upstream approach channel and the outlet end located in a lock chamber, an upper lock head water replenishing gallery system with the inlet end located in the upstream approach channel and the outlet end located in an upper lock head curtain wall, and a fish blocking system comprising a fish blocking electric grid and a fish blocking net. On a lock of a navigable river built flood retarding project and a lock of a new flood retarding project, the fish-passing type lock can be used for greatly saving the project investment in building fish-passing facilities and guaranteeing the ecological balance of rivers.

Description

technical field [0001] The invention relates to the fields of water conservancy engineering and environmental protection engineering, more specifically it is a fish-passing ship lock, and the invention also relates to a fish-passing method using this fish-passing ship lock, which solves the problem of migrating fish passing through river-blocking structures. Backtracking technical issues. Background technique [0002] Building dams on natural rivers blocks the migration passage of fish in the natural rivers. The remedial measures taken at home and abroad are mainly three types: one is to build fish passing facilities, mainly including fishways, fish locks, fish lifts, and fish collection boats; the other is to build artificial simulated spawning grounds in the river; The third is to carry out proliferation and release. [0003] Existing fish remedial measures all have certain effects, but each has advantages and disadvantages. Fishways are generally suitable for water con...
