[0025] The following elaborates on the preferred embodiments of the utility model in conjunction with the attached drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the utility model.

[0026] Please refer to Figure 1 - Figure 6, a fish-scale ecological submerged dam, comprising a fishway main body 1. One side of the fishway main body 1 is fixedly connected with a high-beach ecological board 2. One side of the high-beach ecological board 2 is provided with a low-beach ecological board 3. There are two groups of low-beach ecological boards 3 arranged symmetrically. The high-beach ecological board 2 and the low-beach ecological board 3 are arranged in a fish-scale shape. The bottom of the low-beach ecological board 3 is fixedly connected to one side of the fishway main body 1. A frame 4 is slidably connected to the opposite side of the high-beach ecological board 2 and the low-beach ecological board 3. There are two groups of frames 4 arranged symmetrically. A high-position filter screen 5 is fixedly connected to the inner side of the frame 4. A low-position filter screen 6 is fixedly connected to the side of the frame 4 away from the high-position filter screen 5 and close to the fishway main body 1. Rotating grooves 7 are formed on the sides of the low-beach ecological board 3 and the high-beach ecological board 2 away from the fishway main body 1. Engagement blocks 10 are engaged inside the rotating grooves 7. A rotating rod 9 is fixedly connected inside the engagement blocks 10. A pressing plate 8 is rotatably connected to the outside of the rotating rod 9. The pressing plate 8 abuts against the sides of the high-beach ecological board 2, the frame 4 and the low-beach ecological board 3 away from the fishway main body 1. There are four groups of pressing plates 8 arranged in a rectangular array. Rotating holes 11 are formed inside the rotating rod 9. During operation, first fix the high-beach ecological board 2, the low-beach ecological board 3 and the fishway main body 1 underwater. At this time, the water flow impacts on one side of the high-beach ecological board 2 and the low-beach ecological board 3. The fish-scale shape of the high-beach ecological board 2 and the low-beach ecological board 3 can ensure that the water flow forms a backflow. The water flow can slowly pass through between the low-beach ecological board 3 and the frame 4. In this way, the water level is divided. The space between the high-beach ecological board 2 and the low-beach ecological board 3 is large enough for some fish schools to pass through, ensuring that some fish that need shallow beaches to lay eggs can enter the shallow beaches to lay eggs and then return. In order to prevent some people from passing through the gaps in the low-beach, at this time, the frame 4 cooperates with the high-position filter screen 5 and the low-position filter screen 6 to form a barrier net, so that fish can swim through while humans cannot climb over. When the high-position filter screen 5 and the low-position filter screen 6 accumulate some algae and impurities after long-term use, in order to avoid polluting the nearby water area, the high-position filter screen 5 and the low-position filter screen 6 need to be cleaned and replaced regularly. In this way, the rotating rod 9 can be rotated to disengage the engagement block 10 from the inside of the rotating groove 7. At this time, the pressing plate 8 is removed from the tops of the high-beach ecological board 2, the low-beach ecological board 3 and the frame 4. In this way, the frame 4 can be pulled out for replacement or cleaning.

[0027] The rotating hole 11 runs through the rotating rod 9. On one side of the fishway main body 1 close to the high-beach ecological board 2, a support rod 12 is fixedly connected. There are multiple groups of support rods 12 arranged in a rectangular array on one side of the fishway main body 1. On the side of the support rod 12 away from the fishway main body 1, a walking pedal 13 is fixedly connected. On the top of the walking pedal 13, there is a support frame 15. The support frame 15 is arranged in an "n" shape. On both sides of the support frame 15, safety handles 19 are fixedly connected. There are four groups of safety handles 19 arranged in a rectangular array. On one side of the safety handle 19, it is fixedly connected to the side of the walking pedal 13 away from the support rod 12. A protective cover plate 14 is snap-fitted on the top of the walking pedal 13. The protective cover plate 14 is arranged above the frame 4. On the side of the support frame 15 away from the walking pedal 13, a pulley assembly is arranged. The pulley assembly includes a fixing plate 16. There are multiple groups of fixing plates 16 fixed on the opposite sides of the support frame 15 and the frame 4. On the opposite sides of the fixing plate 16, a support shaft 17 is fixedly connected. A rotating wheel 18 is rotatably connected to the outside of the support shaft 17. During operation, when it is necessary to repair and replace the frame 4 after long-term use, at this time, the protective cover plate 14 is removed from the inside of the walking pedal 13. In this way, the steel cable can be passed along the surface of the rotating wheel 18 close to the support frame 15, and then the steel wire is wound around the surface of the rotating wheel 18 above the frame 4. In this way, pulling the steel cable can drive the frame 4 to be taken out along the inside of the walking pedal 13 where the protective cover plate 14 is fixed, so as to take out the frame 4 for cleaning or replacement operations. The safety handle 19 can block the people walking on the top of the walking pedal 13, avoiding slipping into the water from the surface of the walking pedal 13 due to the water on the top of the walking pedal 13 being too slippery.

[0028] When the utility model is in use, first fix the high-beach ecological board 2, the low-beach ecological board 3 and the fishway main body 1 underwater. At this time, the water flow impacts on one side of the high-beach ecological board 2 and the low-beach ecological board 3. The fish-scale shape of the high-beach ecological board 2 and the low-beach ecological board 3 can ensure that the water flow forms a backflow, and the water flow can slowly pass between the low-beach ecological board 3 and the frame 4. In this way, the water level is divided. The space between the high-beach ecological board 2 and the low-beach dam body 3 is large enough for some fish schools to pass through, ensuring that some fish that need to lay eggs in the shallow beach can enter the shallow beach to lay eggs and then return. In order to prevent some people from passing through the low-beach through the gap, at this time, the frame 4 cooperates with the high-position filter screen 5 and the low-position filter screen 6 to form a barrier net, so that fish can swim through while humans cannot climb over. When the high-position filter screen 5 and the low-position filter screen 6 are used for a long time, some algae and impurities will accumulate inside. In order to avoid polluting the nearby water area, the high-position filter screen 5 and the low-position filter screen 6 need to be cleaned and replaced regularly. In this way, the rotating rod 9 can be rotated to make the clamping block 10 disengage from the inside of the rotating groove 7. At this time, the pressing plate 8 is removed from the tops of the high-beach ecological board 2, the low-beach ecological board 3 and the frame 4, and then the frame 4 can be pulled out for replacement or cleaning. When the frame 4 needs to be overhauled and replaced after long-term use, at this time, the protective cover plate 14 is removed from the inside of the walking pedal 13. In this way, the steel cable can be passed along the surface of the rotating wheel 18 close to the support frame 15, and then the steel wire is wound around the surface of the rotating wheel 18 above the frame 4. In this way, pulling the steel cable can drive the frame 4 to be taken out along the inside of the walking pedal 13 where the protective cover plate 14 is fixed, so as to take out the frame 4 for cleaning or replacement operations. The safety handle 19 can block people walking on the top of the walking pedal 13 to prevent them from slipping into the water from the surface of the walking pedal 13 due to the water on the top of the walking pedal 13 being too slippery.

[0029] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the utility model.
