Abstract

The invention discloses a fish passing system suitable for a reservoir water level large-variation-range ultrahigh arch dam. Segmental and staged lifting of a fish lifting hopper and automatic joining are adopted for dam passing. The fish passing system comprises a dam body. A short fishway, a fish lifting hopper pool, the fish lifting hopper, a first fixed door frame type hoist arranged between the fish lifting hopper pool and a dam downstream road, a first rail type plate electrombile traveling on the dam downstream road, a first rail type tower frame in the lower downstream position of the dam body, a movable trolley located at the top of the first rail type tower frame, a second rail type plate electrombile traveling on a dam rear bridge, a second rail type tower frame located in the higher downstream position of the dam body, and a second fixed door frame type hoist located at the dam top. The short fishway and the fish lifting hopper pool are located on the downstream part of the dam body. The fish lifting hopper is located in the fish lifting hopper pool. The fish passing system is simple and practical in structure, high in automation degree and safety, and simple and convenient to construct, occupied land is saved, and fish dam passing of a reservoir water level large-variation-range ultrahigh arch dam hub can be achieved effectively.

Description

technical field [0001] The invention relates to a fish-passing system, in particular to a fish-passing system suitable for super-high arch dams with large fluctuations in reservoir water level. Background technique [0002] Article 27 of the third chapter of the "Water Law of the People's Republic of China" stipulates that "in the construction of permanent barrages and dams in the migration channels of aquatic organisms, the construction unit shall build fish passing facilities at the same time, or take other remedial measures with the approval of the department authorized by the State Council. "The fish passing structure of prior art mainly comprises fishway (claiming fish ladder again), fish gate, cable machine type fish lifter, collecting and transporting fish boat etc. Fishway is a common facility connecting fish migration routes. Its advantages are simple operation, high operation guarantee rate, low operating cost, less damage to fish, and continuous passing of fish. U...
