[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] See Figures 1 to 9 A simulation device that can adjust the water outlet elevation and pipe slope includes a water tank 1. The bottom of the side wall of the water tank 1 is provided with an inlet pipe 5. A stacked baffle plate is provided on the side wall opposite to the inlet pipe 5. An overflow pipe 6 is provided at the top of the side wall of the water tank 1 with the inlet pipe 5. A water outlet pipe 3 is provided on the stacked baffle plate. The body of the water outlet pipe 3 is connected to an adjustable bracket.

[0030] Preferably, the stacked baffle plate is provided with a water outlet groove 2 on the side facing the inner cavity of the water tank 1, the top of the water outlet groove 2 is the same as the inner cavity of the water tank 1, and the inner cavity of the water outlet groove 2 is connected to the water outlet pipe 3.

[0031] Preferably, the stacked water baffle is composed of multiple clamping plates stacked longitudinally, including a first clamping plate 9 and multiple second clamping plates 12. The height of the water outlet end of the water outlet pipe 3 can be adjusted by changing the positions of the first clamping plate 9 and the second clamping plates 12.

[0032] Preferably, the two side walls of the first card plate 9 are fixedly connected to the water inlet pipe 5 and the water outlet trough 2, respectively.

[0033] Preferably, both the first card plate 9 and the second card plate 12 are provided with a water-stop groove 10 at their lower parts, and a water-stop strip 11 is provided on the top wall of the inner cavity of the water-stop groove 10. The water-stop groove 10 is made of 3mm thick steel plate, and the water-stop strip 11 is made of ABS water-stop strip. The upper card plate is fitted into the top of the lower card plate through the water-stop groove 10, making the overall integrity of the stacked water-stop plates stronger and more secure.

[0034] Preferably, the water tank 1 is provided with a vertical sliding groove 7 at the connection between it and the stacked baffle plate. An elastic sealing strip 8 is provided within the sliding groove 7, and a fixing sill 16 is provided at the bottom of the side of the water tank 1 where the sliding groove 7 is located. This design ensures good airtightness of the enclosed space formed by the water tank and the stacked baffle plate, preventing leakage and providing more accurate quantitative results for water flow during testing. The fixing sill 16 connects the water-stop groove 10 of the bottommost baffle plate to the water tank 1. The inner diameter of the water-stop groove 10 matches the size of the fixing sill 16, ensuring stable and sealed installation.

[0035] Preferably, the adjustable bracket consists of a gantry base 14, a lead screw 13, and a pipe clamp 15. The top end of the gantry base 14 is connected to the bottom end of the lead screw 13 by a nut, and the top end of the lead screw 13 is connected to the pipe clamp 15. This design can provide a certain support for the water outlet pipe 3 while also being adjustable according to the different heights and slopes of the water outlet pipe 3.

[0036] Preferably, the length of the lead screw 13 is adjusted by screwing a nut connected to the lower wall of the top of the portal frame base 14, thereby controlling the overall height of the adjustable bracket, and the pipe clamp 15 is sleeved on the water outlet pipe 3.

[0037] The inlet pipe 5, outlet pipe 3, and overflow pipe 6 are all connected to the external pipe via flange 4.

[0038] Preferably, the connection end between the water outlet pipe 3 and the first clamping plate 9 is provided with a corrugated pipe connection. When the slope of the water outlet pipe 3 is adjusted, displacement will occur at the connection point between the water outlet pipe 3 and the first clamping plate 9, which can be compensated by the extensibility of the corrugated pipe.

[0039] The working principle of this embodiment is as follows:

[0040] The first card plate 9 and the second card plate 12 of the stacked water baffle are placed into the sliding slot 7 of the water tank 1 in a preset order. The height and angle of the water outlet pipe 7 are adjusted by the adjustable bracket. After installation, the sewage is introduced into the water tank 1 from the water inlet pipe 5. When the sewage in the water tank 1 reaches the height of the top opening of the water outlet trough 2, it falls into its inner cavity through the water outlet trough 2 and flows into the subsequent pipe by gravity through the water outlet pipe 3.
