Problems solved by technology

Furthermore, it is impossible to improve the fishway that cannot reach the fish passing effect, often resulting in a huge waste of economy and resources
However, there are very few examples of high-dam fishway projects that have been successfully operated in China, and almost none of the fishway projects that have been built consider the reconstruction of the fishway when the operation effect is not good and the scientific research facilities during the fishway operation period

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, the fishway structure of the present invention includes a fishway 10, and the fishway 10 includes walls on both sides and a group of pool chamber units separated by partitions, one of which is the observation area pool chamber 5; The wall on one side of the fishway 10 is an observation wall 18, and the wall on the other side is a supporting wall 17; a fish guide plate 6 is arranged in the pool room 5 of the observation area, and the fish guide plate 6 is connected to the observation wall. 18 to form a fish passing gap 14, the observation wall 18 corresponding to the fish passing gap 14 is provided with a first observation window 8, and the upstream end of the fish guide plate 6 is connected to the supporting wall 17 with an upstream fish blocking Grille 13, said fish guide plate 6 is connected with downstream ...

Abstract

The invention discloses a fishway structure and a fish-gathering method, in order to observe a fishway, research the fish gathering and conveniently and quickly gather fish. According to the fishway structure, a pool unit is served as an observing area pool; a fish-guiding plate is arranged in the observing area pool; a fish-passing clearance is formed between the fish-guiding plate and an observing wall; a first observing window is arranged on the observing wall corresponding to the fish-passing clearance; an upstream fish corral is connected between an upstream end of the fish-guiding plate and a supporting wall; a downstream fish corral is connected between a downstream end of the fish-guiding plate and the supporting wall; a fishway upstream gate is arranged between one end of the fish-guiding plate on the upstream side and the observing wall; a fish-gathering pool with an inlet is arranged outside the observing wall corresponding to the upstream side of the fish-guiding plate; a fish-gathering pool inlet gate is arranged at the inlet of the fish-gathering pool; and when the fishway upstream gate is closed and the fish-gathering pool inlet gate is opened, the fish-passing clearance is communicated with the fish-gathering pool, so that the fish-gathering can be performed.

Description

technical field [0001] The invention relates to a fishway structure applied on a dam body and a fish collecting method using the fishway structure. Background technique [0002] With the overall development of my country's economy and society, people realize that hydropower will not only bring economic benefits, but also block the communication channels of fish germplasm, resulting in the fragmentation of habitats. With the continuous improvement of environmental protection policies and the continuous increase of environmental supervision of construction projects, the construction of fishways to provide migration channels for fish has gradually become one of the important measures for the protection of aquatic ecology in hydropower projects. [0003] According to the current domestic research results on the swimming ability of fish, the swimming ability of freshwater fish in my country is generally weak, and most of the new domestic water conservancy and hydropower projects ...
