Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, the ship lock project includes the downstream approach channel, the first miter gate of the lower lock, the ship lock chamber, the upper lock first miter gate, and the upper approach channel. Or set program-controlled cyclic jets and program-controlled light cycles on and off to lure fish on both sides to form a program-controlled jet and light fish luring ship lock.

Embodiment 2

[0028] For the completed ship locks, adaptive transformation can be carried out according to the specific conditions. Considering that ships passing the locks may cause safety threats such as collisions to the system facilities, the pipelines can be placed at the bottom of the ship lock system, and the injection pipes can be set below the draft of the ship lock. To ensure the safety of navigation and the safety of the system.

Embodiment 3

[0030] When the ship lock described is multi-stage, the structural settings of the upstream approach channel (5) and the upstream first-stage lock chamber remain unchanged, the structural settings of the downstream approach channel (1) remain unchanged, and the devices of other lock chambers are similar to those of the downstream approach chamber. The structure of the waterway (1) can utilize the natural drop pressure of the reservoir to get final product. When the above-mentioned navigable building is a ship lift, the device structures of the upstream approach channel (5) and the downstream approach channel (1) remain unchanged, and the related devices in the ship container are similar to the ship lock chamber (3)

Abstract

The invention discloses a system for program control circulating jet flow and fish inducing by program control circulating light change for a ship lock or a ship lifting machine. The system comprises a downstream approach channel side wall inner wall, a ship lock chamber or ship lifting machine ship holding box side wall inner side wall, a program control circulating jet flow fish inducing device arranged on the side wall inner wall in a certain range of an upstream approach channel and a program control circulating light change fish inducing light, and consists of a main pipeline, a boost pump and a program control electromagnetic valve jet flow pipe (LED light arranged at the outer periphery of a pipe port, program control circulating light control). Based on a traditional navigation building, the system is newly built or transformed to achieve the effect of fishes passing through a dam from downstream to upstream in normal use process of navigation facilities, protects the river fish ecology, reduces the fish passing water consumption and the energy consumption, and realizes the purposes of reducing the engineering investment, reducing the operation cost and giving consideration to engineering and ecological and environmental benefits.

Description

technical field [0001] The invention relates to an additional device for a ship lock or a ship lift, in particular to a dynamic small environment in which a small-scale fish-attracting jet that circulates upstream and changes in light is created by utilizing the stress characteristics and phototaxis characteristics of fish to reverse water flow , a device for realizing navigation facilities (ship locks, ship lifts) passing fish, belonging to the field of water conservancy and hydropower engineering environmental protection. 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. At present, the ma...
