When a large amount of rain comes in summer, and the baffle is subjected to the pressure of the water flow flowing downstream to the pressure generated by the ecological flow, the baffle will rotate around the connecting shaft. The arc guide groove is the rotation range of the baffle. When the baffle is tilted, the water will pass through the baffle and drive the driving impeller to rotate. When the driving impeller rotates, the crank connecting rod can be driven to rotate, and the cylinder can be driven. The circular drive of the cylinder can inflate the rubber dam inside the rubber pop-up box. The inflation and pop-up of the rubber dam can form a curtain wall above the rubber pop-up box to block water, improve the water storage capacity, reduce the water flow and ensure a certain ecological flow downstream. In addition, the Yongshui Weir can reduce the amount of levees, sluices, and spillways, and can automatically increase the water storage capacity when the flood season comes, and ensure the ecological discharge flow.

[0009] 2. The guide plate of the ecological Yongshui Weir is arranged in an eight-shaped shape, which can conveniently guide the water flow to the driving impeller, so that the water flow can drive the driving impeller hydraulically and improve the transmission efficiency.

[0010] 3. The ecological Yongshui weir has a buffer connector composed of a sleeve, a connecting rod and a buffer spring arranged inside the sleeve. The connecting rod is movably sleeved inside the sleeve, and the spring can provide buffer support for the connecting rod. The buffer connector is arranged between the weir body and the baffle plate, which can effectively provide buffer support for the baffle plate, facilitate the functional interchange of the baffle plate's baffle function and the driving component, and improve the water blocking capacity.
