In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-3 As shown, a supernatant overflow valve device includes a telescopic bellows assembly 1, a support rail assembly 2 and a hydraulic telescopic assembly 3; the telescopic bellows assembly 1 is connected to the lower end of the support rail assembly 2, the hydraulic telescopic assembly 3 is connected to the upper end of the support rail assembly 2, and the output end of the hydraulic telescopic assembly 3 is connected to the telescopic bellows assembly 1, driving the upper end of the telescopic bellows assembly 1 to move up and down.

[0023] Specifically, the upper port of the telescopic bellows assembly 1 is driven up and down by the hydraulic telescopic assembly 3, so that the supernatant at the top of the tailwater pool can flow into the drain through the bellows, and the muddy water at the bottom is blocked by the bellows and retained in the pool, so as to improve the efficiency of the residual water treatment operation.

[0024] Specifically, the support rail assembly 2 includes a steel frame 10, two rails 11, a transverse steel connecting rod 12, a first vertical steel connecting rod 8 and a second vertical steel connecting rod 9; a rail 11 is connected to each of the two sides of the steel frame 10, and the two ends of the transverse steel connecting rod 12 are respectively slidably connected to the two rails 11, and the two ends of the transverse steel connecting rod 12 are respectively connected to the first vertical steel connecting rod 8 and the second vertical steel connecting rod 9, and the lower ends of the first vertical steel connecting rod 8 and the second vertical steel connecting rod 9 are connected to the telescopic bellows assembly 1. The first vertical steel connecting rod 8 and the second vertical steel connecting rod 9 are both located inside the steel frame 10.

[0025] Specifically, the telescopic bellows assembly 1 includes a telescopic tube body 5, a right-angle tube body 6 and a stainless steel clamp 7; the telescopic tube body 5 is arranged at the upper end of the right-angle tube body 6, the upper end of the telescopic tube body 5 is connected to the stainless steel clamp 7, and the two sides of the stainless steel clamp 7 are respectively connected to the lower ends of the first vertical steel connecting rod 8 and the second vertical steel connecting rod 9. The inner wall of the stainless steel clamp 7 is connected to the filter screen 4. The upper end of the right-angle tube body 6 is connected to the inner wall of the lower end of the steel frame 10. The right-angle tube body 6 is bent at 90 degrees, and the end is directly connected to the drain outlet. The top of the vertical part of the bellows at the telescopic tube body 5 adjusts the height in real time according to the level of the supernatant.

[0026] Specifically, the hydraulic telescopic assembly 3 includes a hydraulic telescopic rod 13, an electric hydraulic pump 14 and a hydraulic oil pipe 15; the hydraulic telescopic rod 13 and the electric hydraulic pump 14 are both connected to the steel frame 10, and the output end of the hydraulic telescopic rod 13 penetrates the steel frame 10 and is connected to the middle of the transverse steel connecting rod 12; the electric hydraulic pump 14 is connected to the hydraulic telescopic rod 13 through the hydraulic oil pipe 15. The electric hydraulic pump 14 provides power for the movement of the hydraulic telescopic rod 13.

[0027] When in use, the electric hydraulic pump 14 provides power to the hydraulic telescopic rod 13, causing the hydraulic telescopic rod 13 to move (the output end extends or retracts). When the hydraulic telescopic rod 13 is extended, it drives the transverse steel connecting rod 12 to move downward in the guide rail 11. The downward movement of the transverse steel connecting rod 1 drives the first vertical steel connecting rod 8 and the second vertical steel connecting rod 9 to move downward. The downward movement of the first vertical steel connecting rod 8 and the second vertical steel connecting rod 9 drives the telescopic tube body 5 to contract, causing the port of the telescopic tube body 5 to drop; conversely, the retraction of the hydraulic telescopic rod 13 can drive the port of the telescopic tube body 5 to rise; therefore, the supernatant overflow valve device can allow the supernatant at the top of the tailwater pool to flow into the drain outlet through the bellows through the upward and downward movable adjustment of the bellows port, and the muddy water at the bottom is blocked by the bellows and retained in the pool, so as to improve the efficiency of the residual water treatment operation.
