Embodiment 1

[0033] Such as figure 1 As shown, the existing ship lock includes a lock chamber, an upstream gate, and a downstream gate. When adding a fish passing device, a plurality of water flow generating devices 1 are arranged on the outside of the upstream gate and the downstream gate away from the lock chamber, and a water flow generator is also embedded in the outside of the downstream gate. Device 1, multiple water flow generators 1 and underwater fish collection lamps 2 are installed on both sides of the lock chamber, and an underwater fish driving lamp 3 is installed on the side of the upstream gate close to the lock chamber, and the underwater fish driving lamp 3 is embedded in the upstream In the gate, electric grids 5 are arranged on both sides of the downstream of the lock, which are opened obliquely outwardly, and the bottom of the lock chamber is centered with a sound wave fish driving device 4, and the above-mentioned structure constitutes a device that can use the lock to ...

Embodiment 2

[0035] The device that utilizes the ship lock to realize fish passing includes a plurality of water flow generating devices 1 arranged upstream of the ship lock, the side wall of the lock chamber and downstream, and the downstream side of the downstream gate of the ship lock is also provided with a water flow generating device 1. An underwater fish-collecting lamp 2 is arranged on the top, and the underwater fish-collecting lamp 2 is set at the lower end of the inner mooring column, and an underwater fish-repelling lamp 3 is provided on the side of the upstream gate close to the lock chamber, and an acoustic wave fish-repelling device is provided at the bottom of the lock chamber 4.

[0036] In addition, the underwater fish collecting lights, underwater fish driving lights and water flow generating devices are symmetrically arranged on the left and right sides of the ship lock. According to the specific conditions and needs of the ship lock, all devices can also be arranged in...

Embodiment 3

[0037]Embodiment 3: When the ship lock is a multi-stage ship lock, the structural settings in the lock chamber remain unchanged, and the upstream and downstream settings of the ship lock remain unchanged; that is, the devices in the lock chamber can be arranged indiscriminately. The water flow generating device is still arranged outside the upper gate of the uppermost ship lock, and the water flow generator and electric grid are still arranged outside the lowermost lock gate.

[0038] Adopt above-mentioned device to carry out the method for fish, concrete steps are:

[0039] 1) Close all the gates of the ship lock, open the water flow generating device downstream of the ship lock, and lure the fish to the downstream gate through the water flow;

[0040] 2) Open the downstream gate of the ship lock, and at the same time start the water flow generating device and underwater fish collection lamp in the lock room to guide the fish to swim and gather in the lock room;

[0041] 3) ...

Abstract

The invention discloses a device for realizing fish passing by utilizing a ship lock. The device comprises multiple water flow generating devices arranged in the upstream of the ship lock, on the side walls of a lock chamber and in the downstream of the ship lock, water flow generating devices are arranged on the downstream side of a downstream lock gate of the ship lock, underwater fish collecting lamps are arranged on two side walls in the lock chamber, underwater fish driving lamps are arranged one side, close to the lock chamber, of an upstream lock gate, and sound wave fish driving devices are arranged at the bottom of the lock chamber. An existing ship lock building is utilized and additional devices are arranged to achieve effect enabling fishes to pass a dam, fish passing effect is better than that of conventional fishways, and the device and the method are suitable for different fishes; the ship lock and a fishway are integrated into a whole, so that working efficiency is improved, operating cost is lowered, and the device and the method are suitable for popularization.

Description

technical field [0001] The invention relates to an additional device for a ship lock, in particular to a device for realizing fish passing through a ship lock by utilizing the stress characteristics of fish to sound, light, electricity and water flow, and belongs to the field of water conservancy and hydropower engineering environments. Background technique [0002] Water conservancy projects build barrages for flood control, power generation, shipping, water supply, etc., but the construction of dams destroys the biological continuity of the river, blocks the passage of migratory and semi-migratory fish, and reduces the biodiversity of the river . There are three main types of "fish saving" measures adopted by foreign countries: the first type is to build fish passing facilities, mainly including fishways, fish locks, fish lifts, and fishing boats; the second type is to build artificial simulated spawning grounds The third category is to carry out artificial breeding and r...
