[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6This utility model provides a technical solution: a multi-stage stepped drop structure, including a step 1, a vertical section 2, a flow guide plate 3, a separator 4, a flow guide channel 5, an inlet 6, a buffer channel 7, an outlet 8, fixing bolts 9, and fixing bolt slots 10. A vertical section 2 is fixedly connected to one side of the step 1. A flow guide plate 3 is attached between the step 1 and the vertical section 2, and a flow guide channel 5 is formed on the inner wall of the flow guide plate 3. The flow guide plate 3 is bolted to the step 1 and the vertical section 2 using the fixing bolts 9 and the fixing bolt slots 10. The shape of the rear side of the flow guide plate 3 matches the shape between the step 1 and the vertical section 2, making it easy to install and remove the matching bolts for quick replacement. The front side of the flow guide plate 3 and the flow guide channel 5 are both arc-shaped structures, allowing for double-layer flow guidance with excellent effect. The flow guide plate 3 is made of honeycomb polytetrafluoroethylene material. This design allows the flow guide plate 3 to be highly corrosion resistant, lightweight, and easy to handle and transport. The flow guide channel 5 is flush with the buffer channel 7 through the inlet 6 and outlet 8. The buffer channel 7 has an inclined groove structure, which allows the flow guide channel 5 to buffer the flow with the buffer channel 7, further enhancing the flow stability and improving the effect. The inner wall of the flow guide channel 5 is vertically fixed with a partition block 4, and one end of the flow guide channel 5 has an inlet 6. The partition block 4 is distributed in a grid structure on the inner wall of the flow guide channel 5, and one end of the partition block 4 has a triangular structure, which allows the partition block 4 to divert the water flow and enhance the flow guiding effect. The other end of the flow guide channel 5 has an outlet 8. The inner wall corner of the flow guide plate 3 is connected by a fixing bolt 9. The corner of the step 1 and the vertical section of the step 2 is fixedly connected with a fixing bolt groove 10. The fixing bolt 9 is installed by inserting and connecting with the fixing bolt groove 10. A buffer groove 7 is provided at the connection between one side of the step 1 and the upper end of the vertical section of the step 2.

[0021] Working principle: When using this multi-stage stepped drop structure, firstly, the flow guide plate 3 of the device is attached and spliced ​​with the step 1 and the vertical section 2 of the step. Then, it is fixed by bolts 9 and bolt slots 10. When the water flows through the step 1 and the vertical section 2 of the step, it will be guided into the inlet 6 through the buffer trough 7 and guided in an arc shape through the flow guide trough 5. Then, it will be divided by the grid through the partition block 4 and then flow out through the outlet 8 and flow to another set of buffer troughs 7 for continuous buffering. When the water flow increases, it can be guided by the double layer of the flow guide plate 3 and the flow guide trough 5, which also effectively prevents corrosion. When the flow guide plate 3 is damaged, it can be quickly disassembled and replaced. This is the usage process of this multi-stage stepped drop structure.
