Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

As shown in fig. 1 and 5, the fish shelter device for riverway slopes comprises a shelter groove 1, wherein the shelter groove 1 is arranged in an installation groove X102 dug on a slope X101 of the river channel X1 along the length direction of the conventional river channel X1, the shelter groove 1 is formed by enclosing a first side plate 101, a second side plate 102 and a bottom plate 103 vertically and fixedly connected to the lower edges of the first side plate 101 and the second side plate 102, the cavity in the middle is a fish containing cavity 2, and the first side plate 101, the second side plate 102 and the bottom plate 103 can be an integrally formed structure during actual processing; in addition, a top cover 3 is adapted to the shelter groove 1, and a plurality of fish passing holes 4 through which fish can pass are distributed on the top cover 3.

Further, the first side plate 101 is a straight plate structure that is consistent with the length direction of the river channel X1 (i.e. consistent with the water flow direction X103 of the river channel X1), the second side plate 102 is an inclined plate structure that is inclined from the front end to the rear end toward the bottom of the river channel X1 (i.e. inclined from the water-facing end to the back water end toward the river bottom X104 along the water flow direction X103 of the river channel X1), and the specific inclination of the second side plate 102 can be 2%, so that the fish holding cavity 2 is a trapezoidal cavity with gradually increasing width from the front to the back, so as to reduce the deposition generated in the fish holding cavity 2 after the shelter trough 1 is laid on the slope X101 of the river channel X1D by the washing of the water flow, and facilitate the later management and maintenance.

Further, as shown in fig. 2 and 3, a clamping groove 5 is formed on the upper edges of the first side plate 101 and the second side plate 102, the clamping groove 5 is formed along the length direction of the first side plate 101 and the second side plate 102, and meanwhile, a clamping protrusion 6 adapted to the clamping groove 5 is disposed on the bottom wall of the top cover 3, so that the top cover 3 can be tightly fastened to the shelter groove 1.

Further, as shown in fig. 4, the fish passing holes 4 are composed of large holes 401 with a diameter of 150mm, medium holes 402 with a diameter of 100mm and small holes 403 with a diameter of 50mm, and are randomly arranged on the top cover 3, so that fishes with different sizes can correspondingly enter the fish accommodating cavity 2 through the large holes 401, the medium holes 402 or the small holes 403 to avoid.

Further, for convenience of manufacturing and installation and laying on site, the shelter trough 1 may be a multi-section structure spliced side by side, and similarly, the top cover 3 may also be a multi-section structure adapted to the shelter trough 1. During actual processing, the shelter groove 1 and the top cover 3 are both of six-section structures (as shown in fig. 1), and the length of each section of the shelter groove 1 and the length of each section of the top cover 3 are both 900 mm; in addition, the first side plate 101, the second side plate 102 and the bottom plate 103 which form the shelter trough 1 are all made of steel plates with the thickness of 100mm, the top cover 3 is made of steel plates with the thickness of 50mm, the height of the first side plate 101 and the height of the second side plate 102 are determined by the actual slope of the side slope X101 of the river channel X1, and only the slope of the top cover 3 covering the first side plate 101 and the second side plate 102 is consistent with the slope of the side slope X101, and the height of the first side plate 101 is not less than 900mm, and the height of the second side plate 102 is not less than 500 mm. In addition, the length of the clamping groove 5, the width of the clamping groove 5 and the depth of the clamping groove 5 are 900mm, 30mm and 30mm, the clamping protrusion 6 correspondingly arranged on the bottom wall of each section of the top cover 3 is 900mm, 30mm and 30mm, and the clamping groove 5 and the clamping protrusion 6 can be matched and clamped.

During actual installation and laying, as shown in fig. 5 and 6, an installation groove X102 is excavated on a side slope X101 of a river channel X1, and it is noted that the installation groove X102 should be arranged below a normal water level line X105 and can be arranged at any position at different heights, and in addition, the size of the installation groove X102 needs to be consistent with that of the shelter groove 1 with the six-segment structure; then, the shelter groove 1 is installed in the installation groove X102 section by section, and the top cover 3 is fastened one by one, so as to ensure that the upper surface of the top cover 3 is consistent with the side slope X101 of the river channel X1. When the dredging water level of the river channel is reduced, some river water can be stored in the fish accommodating cavity 2, so that the fishes can be hidden in the fish accommodating cavity 2 through the fish passing holes 4 (namely the large holes 401, the middle holes 402 or the small holes 403) in the top cover 3, the large-scale death of the fishes caused by the dredging of the river channel is avoided, and the serious damage to the ecology of the river channel caused by the dredging engineering is avoided; of course, the fish containment chamber 2 of the shelter 1 can also be used as a spawning site for fish in a non-desilted state. In addition, the shelter trough 1 can be used as a shelter for fishes, frogs or other living things in a river.
