Embodiment 1

[0048] Such as figure 1 , 2 As shown, a high dam fish transportation device based on the ship lock water delivery system provided in this embodiment is to combine the ship lock water delivery system with the lifting fish, that is, to use the ship lock irrigation and discharge process to simultaneously implement irrigation and drainage of the lifting fish well. Drain water to realize the water level change of the fish well, so as to realize the lifting of the buoy, and then drive the vertical movement of the mesh plate to achieve the purpose of fish transportation.

[0049] Specifically, the ship lock water delivery system includes an irrigation corridor 1 connected to the ship lock chamber (not shown) and having an irrigation valve 2 and a discharge corridor 4 having a discharge valve 5. The high dam fish transportation device includes The water pipeline 3, the fish well 11, the fish assembly, the upstream fish passage 13 and the downstream fish passage 8, the water pipeline ...

Embodiment 2

[0061] Such as Figure 6 As shown, the difference between the present embodiment and the first embodiment is that the high dam fish transportation device also includes a fish collection pond 6 connected to the downstream fish passage 8, and a fish collection lamp 7 is arranged in the fish collection pond 6. In this way, the fish can be lured into the fish collection pond as a transfer in advance before passing through the fish channel downstream, so that the fish can better enter the fish well.

[0062] In the present embodiment, the high dam fish transportation device also includes a drainage pipeline 21 connected between the energy dissipation components set at the bottom of the fish collection pond 6 and the fish well 11, the drainage pipeline 21 is provided with a drainage valve 20, and the fish collection pond 6 and the drainage pipeline 21 is connected by another described energy dissipation assembly. In this way, with the maintenance valve, the upper gate and the lower...

Embodiment 3

[0071] Such as Figure 7 As shown, the high dam fish transportation device in the present embodiment also includes a water filling pipeline 24 with a water shutoff valve 22 and a water filling valve 23 arranged in sequence, and the water filling pipeline 24 is connected to the upstream reservoir area at one end of the water shutoff valve 22 , One end of the water valve 23 is connected to the water delivery pipeline 3 and is located between the two maintenance valves 19 .

[0072] Like this, its transporting fish method comprises the steps:

[0073] B1. The irrigation valve, drain valve, upper gate, water filling valve and two maintenance valves are all closed, and the lower gate and water shutoff valve are open, so that fish can swim into the fish well through the downstream fish passage;

[0074] B2. Close the lower gate, open the water filling valve, and the rising fish well water level will drive the fish rising component to drive the fish up. After the rising fish well wa...

Abstract

The invention discloses a high-dam fish transporting device based on a ship lock water conveying system and an operation method and belongs to the crossing field of ship lock engineering and ecological protection. The device comprises a water conveying pipeline, a fish lifting well, a fish lifting assembly, an upstream fish passing channel and a downstream fish passing channel. The water conveyingpipeline and a ship lock chamber are arranged in parallel and are arranged behind an irrigation valve and in front of a drainage valve; the fish lifting well is connected with the water conveying pipeline through an energy dissipation assembly, connected with the downstream fish passing channel through a lower gate and connected with the upstream fish passing channel through an upper gate. The fish lifting assembly is arranged in the fish lifting well and composed of a net plate and buoys, at least three buoy wells which are communicated with the fish lifting well and used for containing thebuoys are evenly distributed in the circumferential direction of the fish lifting well, and the net plate is arranged in the fish lifting well and connected with the buoys. According to the invention,a ship lock water conveying system suitable for the high-water-head condition is combined with fish lifting, and irrigation and drainage are synchronously implemented on the fish lifting well in theship lock irrigation and drainage process, so the water level of the fish lifting well is changed, and therefore the buoys ascend and descend, and then the net plate is driven to vertically move to achieve the purpose of fish transporting.

Description

technical field [0001] The invention belongs to the technical field of ship lock engineering and ecological protection, and relates to a high dam fish transportation device and an operating method based on a ship lock water delivery system. Background technique [0002] Building dams in rivers can play a significant role in flood control, power generation and navigation. However, the construction of the dam cuts off the continuity of the river, thereby cutting off the migration channel of fish, changing the environment of fish habitat, and causing a great impact on the ecological environment. In order to solve the contradiction between dam construction and fish protection, the research and construction of fish passing facilities has become very important. At present, the fish passing facilities that are widely used mainly include fishways and fish elevators. Among them, the fishway has the characteristics of large one-time investment and high water head difference. Especia...
