Embodiment

[0033] Such as figure 1 , 2 As shown, the present invention provides a novel fishway system that integrates the functions of fish school migration, drifting and sightseeing. The present invention includes a fishway, a fishway partition 1 , a sightseeing passage 2 , a safety and maintenance passage 3 , and a safety gate mechanism 8 .

[0034] The fishway, as the core of this technology, consists of a plurality of first transverse passages 4, first vertical passages 5, second transverse passages 6, and second vertical passages 7 according to the "first transverse passage-first vertical passage The law of channel-second transverse channel-second vertical channel" is composed of sequential connections from top to bottom, forming a surrounding spiral quadrilateral structure; and, the first horizontal channel at the bottom is connected with the downstream river, and the other first horizontal channels are all Each of them communicates with the outside of the upstream reservoir thr...

Abstract

The invention discloses a spiral building type fish way system integrating a sightseeing function and a drifting function. The spiral building type fish way system integrating the sightseeing functionand the drifting function mainly solves the problems that in the prior art, migration of fish schools under any water level cannot be achieved, and the water channel maintaining capital is in shortage. The system comprises a fish way, fish way partition plates, a sightseeing channel and a safety and maintenance channel. The fish way is composed of multiple first transverse channels, a first vertical channel, a second transverse channel and a second vertical channel, where are sequentially connected according to the above rule to form a spiral quadrilateral structure which is used for achieving fish passing and drifting. In addition, an inductive lifting stacking gate mechanism is arranged at the communicating position of each connecting channel and the outer side of a reservoir, and a safety gate mechanism is further arranged on the inner side of the reservoir. The multiple fish way partition plates are arranged in the middle of the fish way at intervals. By means of the above scheme,fish school migration in any time period can be achieved, the capital problem of fish way maintenance is solved, and very high practical value and popularization value are achieved.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a spiral building-type fishway system integrating sightseeing and rafting functions. Background technique [0002] With the development of my country's hydropower industry, a large number of small and medium-sized hydropower dams have been built one after another. These hydropower dams have played a huge role in flood control, irrigation, power generation, water supply, shipping, aquaculture, etc., and have achieved significant economic benefits. However, people have gradually realized that hydropower will have negative impacts on fish while bringing economic benefits. The dam blocked the passage for fish to migrate and spawn, causing many fish to swim upstream to spawn Hit the dam and died. In order to protect natural fishery resources and ensure the continuity and diversity of aquatic ecosystems, the main restoration measures currently taken are to build fishways i...
