DETAILED DESCRIPTION

[0023] The technical solutions in the utility model will be described clearly and completely below with reference to the drawings, and the preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figures 1-4 shown, the specific embodiment adopts the following technical solutions: it comprises a stairway 1, a plurality of stairway 1s are arranged on a riverbed;

[0025] It further comprises:

[0026] The flow pipe group 2 is fixedly arranged on the ladder 1, and the flow pipe group 2 is connected with the tapered pipes 3 through the convenient dismounting mechanism 7;

[0027] The water baffle 4 is fixedly arranged on the upper portion of the flow pipe group 2, the left side wall of the water baffle 4 is provided with the reinforcing rib plates 10 on the front and back sides, the reinforcing rib plates 10 are fixedly arranged on the flow pipe group 2, the reinforcing rib plates 10 can improve the connection strength of the water baffle 4 and the flow pipe, the water baffle 4 is prevented from being separated from or broken from the flow pipe due to the influence of the water flow for a long time, the front and back sides of the water baffle 4 are provided with the protective baffles 5, the protective baffles 5 are fixedly arranged on the flow pipe group 2, the protective baffles 5 are provided with the flow holes 9, the water flow above the flow pipe group 2 can flow through the flow holes 9, the flow impact force of the water flow in the flow pipe group 2 is reduced, and the convenience of the fish swimming in the flow pipe is further improved;

[0028] The partition plates 6 are fixedly arranged on the ladder 1, and the flow pipe group 2 is connected with the side wall of the partition plate 6;

[0029] The convenient dismounting mechanism 7 comprises:

[0030] The mounting frame 7-1 is arranged on the left side of the flow pipe group 2, and the front and back side walls of the flow pipe group 2 and the mounting frame 7-1 are provided with the matched semicircular grooves 11;

[0031] The horizontal plate 7-2 is movably arranged above the mounting frame 7-1, the lower portion of the horizontal plate 7-2 is provided with the vertical rods 7-3 on the front and back sides, the vertical rods 7-3 are movably inserted into the matched two semicircular grooves 11, the right side wall of the horizontal plate 7-2 is provided with the plug blocks 8, the plug blocks 8 are movably inserted into the grooves 12 arranged on the flow pipe group 2, and the plug blocks 8 can be used to share the stress of the connection between the horizontal plate 7-2 and the vertical rods 7-3 when the horizontal plate 7-2 is subjected to the transverse impact of the water flow;
