Embodiment 1

[0028] Such as Figure 1 to Figure 4 Shown a kind of vertical seam type fishway that possesses the function of small-scale baiting field overwintering field, comprises fishway pond room dividing plate 3, fishway inner side wall 4, fishway outer side wall 5; Fishway inner side wall 4 and The outer side walls 5 of the fishway are fixed side by side to form a fishway, and a plurality of fishway pond room partitions 3 are fixed horizontally along the fishway; the bottom of the end face of the fishway has a fishway inlet 1; the outer side walls 5 of the fishway are the water-facing surface, There is an openable structure on the side wall 5 outside the fishway.

Embodiment 2

[0030] Adopt the scheme of embodiment 1, and:

[0031] Among the plurality of fishway pond chamber partitions 3 , the fishway pond chamber partitions 3 fixed on the fishway inner side wall 4 and the fishway pond chamber partitions 3 fixed on the fishway outer side wall 5 are alternately distributed.

Embodiment 3

[0033] Adopt the scheme of embodiment 1, and:

[0034] The openable and closable structure is the side wall movable structure 12, and each side wall movable structure 12 all constitutes one section of the side wall 5 outside the fishway.

Abstract

The invention provides a vertical seam type fishway with functions of a small-sized feeding field and an overwintering field. The vertical seam type fishway comprises fishway pond chamber partition plates, a fishway inner side wall and a fishway outer side wall, wherein the fishway inner side wall and the fishway outer side wall are fixed side by side to form the fishway, a plurality of fishway pond chamber partition plates are transversely fixed along the fishway, and a fishway inlet is formed in the bottom of the fishway end face. According to the vertical seam type fishway, the outer side wall of the upstream face of the vertical seam type fishway is transformed into a movable structure capable of being opened and closed, in the non-fish-passing season, after a side wall control system controls the side wall movable structure to be opened along a side wall sliding rail, a spur dike-like type forming a certain angle with the side wall is formed, q plurality of parent fish nest brick structures are arranged on the outer side wall, and the fishway is constructed into an open type small water area suitable for fish feeding and overwintering, so that a long-term stable inhabiting, breeding and migration space for local fishes can be cultivated, the service time of the fishway can be prolonged, the use function of the fishway can be fully excavated, and application research of the fishway is facilitated.

Description

technical field [0001] The invention relates to a vertically slotted fishway with the function of a small bait feeding ground and overwintering ground, and belongs to the field of water conservancy and hydropower ecological protection. Background technique [0002] Fish-passing facilities are mandatory ecological protection measures proposed by relevant national policies for river damming projects, and have become one of the important indicators for the review and approval of water conservancy and hydropower projects. As one of the main types of fish passage facilities, fishways are generally used in medium and low head dams. For example, fishways in Changzhou, Guangxi, and first-level fishways in Zhentou Dam, Dadu River have achieved relatively good fish passage effects; in addition, There are also cases where vertical slot fishways have been built on some high dams and have been operated with good results. The vertical seam fishway is a kind of pond fishway, which is char...
