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

[0031] The embodiment of the application provides a sewage discharge tank, by arranging the energy dissipation part 1, the potential energy of the sewage entering the energy dissipation part 1 can be weakened, the flow of the sewage is facilitated to be measured by the flowmeter in the later period, the effect of facilitating the discharge of the sewage quantity and improving the accuracy of the sewage quantity statistics is achieved.

[0032] The following describes in detail a sewage discharge tank provided in an embodiment of this application, with reference to the accompanying drawings. Figure 1 , Figure 2 As shown, it includes an energy dissipation section 1 and a drainage section 2, which are connected to each other. An inlet pipe 3 is connected to one side of the energy dissipation section 1 to eliminate the potential energy of the sewage entering the energy dissipation section 1 through the inlet pipe 3. A drainage pipe 5 is connected to the side of the drainage section 2 away from the energy dissipation section 1 to measure and discharge the sewage after the potential energy has been eliminated by the energy dissipation section 1.

[0033] In this embodiment, as Figure 1 , Figure 2 As shown, the wastewater discharge tank includes an energy dissipation section 1 and a drainage section 2. Wastewater enters the energy dissipation section 1 through the inlet pipe 3, where its potential energy is eliminated before being discharged, thus achieving energy dissipation of the wastewater and making the water flow into the drainage section 2 more uniform. Since the energy dissipation section 1 and the drainage section 2 are connected, the discharged water can enter the drainage section 2 and be discharged through the drain pipe 5, thereby realizing the discharge of wastewater and the measurement of the discharge volume. This application, by eliminating the potential energy of wastewater, can solve the problem of inaccurate wastewater volume statistics in the prior art, achieving the effect of facilitating wastewater discharge and improving the accuracy of wastewater volume statistics.

[0034] In one embodiment, refer to Figure 1 As shown, the energy dissipation section 1 includes multiple energy dissipation tanks 11, and adjacent energy dissipation tanks 11 are connected by water passages 12 to gradually dissipate the potential energy of the sewage entering the energy dissipation section 1.

[0035] Here, as Figure 1 As shown, the energy dissipation section 1 includes multiple energy dissipation tanks 11, all of which are rectangular and connected in series in the vertical direction. Adjacent energy dissipation tanks 11 are connected through water passages 12, thereby gradually eliminating the potential energy of the sewage entering the energy dissipation section 1, so as to make the sewage flow more uniform.

[0036] In one feasible approach, refer to Figure 1 As shown, there are three energy dissipation pools 11, which are connected in sequence through water passages 12. All three energy dissipation pools 11 are made of 316L material with a thickness of 2mm.

[0037] Here, as Figure 1As shown, there are three energy dissipation pools 11, including a first energy dissipation pool 111, a second energy dissipation pool 112, and a third energy dissipation pool 113. The first energy dissipation pool 111 and the second energy dissipation pool 112 are connected by a water passage 12, and the second energy dissipation pool 112 and the third energy dissipation pool 113 are also connected by a water passage 12. The first energy dissipation pool 111, the second energy dissipation pool 112, and the third energy dissipation pool 113 are all made of 316L material with a thickness of 2mm, and the inner walls of the energy dissipation pools 11 are all covered with sky blue ceramic tiles, while the outer walls are covered with white ceramic tiles.

[0038] The above operation, with the setting of three energy dissipation tanks 11, can eliminate the potential energy of the sewage entering the energy dissipation section 1 in stages; at the same time, since the hardness of the liquor wastewater is relatively high, the surface of the energy dissipation tank 11 is prone to scaling, which affects the appearance, and acid and alkaline detergents are often used for later cleaning and maintenance, which can easily corrode the tank wall. Therefore, 316L material plate with a thickness of 2mm is used to facilitate later cleaning and maintenance.

[0039] In one embodiment, refer to Figure 1 , Figure 3 As shown, there are three water passages 12, including a first water passage 121, a second water passage 122 and a third water passage 123; the first water passage 121 and the second water passage 122 are located at adjacent positions in the three energy dissipation pools 11, and the third water passage 123 is located at the position adjacent to the energy dissipation pool 11 and the drainage section 2.

[0040] Here, as Figure 1 , Figure 3As shown, three water passages are provided, including a first water passage 121, a second water passage 122, and a third water passage 123. Each pair of adjacent energy dissipation tanks 111, 112, and 113 is equipped with a partition wall. The first water passage 121 is located at the partition wall between the first energy dissipation tank 111 and the second energy dissipation tank 112, and both the first and second energy dissipation tanks 111 and 112 have water passage holes at the location of the first water passage 121 to allow wastewater to flow from the first energy dissipation tank 111 into the second energy dissipation tank 112 through the first water passage 121. The second water passage 122 is located at the partition wall between the second energy dissipation tank 112 and the third energy dissipation tank 113, and the second and third energy dissipation tanks 112 and 113 are connected by a partition wall. Each of the water passages 122 has a water passage hole to allow sewage to flow from the second energy dissipation tank 112 into the second energy dissipation tank 113 through the water passage 122. A partition wall is also provided between the third energy dissipation tank 113 and the drainage section 2. The third water passage 123 is located at the partition wall between the third energy dissipation tank 112 and the drainage section 2, and both the third energy dissipation tank 113 and the drainage section 2 have water passage holes at the location of the third water passage 123 to allow sewage to flow from the third energy dissipation tank 113 into the drainage section 2 through the third water passage 123. The water passages 122 allow sewage to flow sequentially into different energy dissipation tanks 11 before entering the drainage section 2.

[0041] In one feasible approach, refer to Figure 2 , Figure 3 As shown, the first water passage 121, the second water passage 122, and the third water passage 123 have different heights, which are used to eliminate the potential energy of the sewage entering the energy dissipation tank 11 in stages; among them, the bottom elevation of the first water passage 121 is -0.6m, the bottom elevation of the second water passage 122 is 0m, and the bottom elevation of the third water passage 123 is -0.6m.

[0042] Here, as Figure 2 , Figure 3 As shown, the first water passage 121, the second water passage 122, and the third water passage 123 have different heights. The bottom elevation of the first water passage 121 is -0.6m, the bottom elevation of the second water passage 122 is 0m, and the bottom elevation of the third water passage 123 is -0.6m. This allows for the gradual elimination of the potential energy of the sewage entering the energy dissipation tank 11. That is, when the sewage flows from a higher elevation area to a lower elevation water passage, the water level difference will cause changes in the water flow velocity and energy, causing the water to consume energy during passage, thereby achieving the purpose of energy dissipation.

[0043] In another possible approach, refer to Figure 2 , Figure 3As shown, the first water passage 121, the second water passage 122, and the third water passage 123 have different sizes and are used to rationally distribute the sewage flow entering the energy dissipation tank 11; wherein, the size of the first water passage 121 is 1200mm×200mm, the size of the second water passage 122 is 1200mm×200mm, and the size of the third water passage 123 is 600mm×400mm.

[0044] Here, refer to Figure 2 , Figure 3 As shown, the three water passages have different sizes: the first water passage 121 is 1200mm × 200mm, the second water passage 122 is 1200mm × 200mm, and the third water passage 123 is 600mm × 400mm. By setting water passages 12 of different sizes, larger water passages 12 (e.g., 1200 × 200mm) can handle larger flow rates of sewage in a short time, suitable for areas with potentially large catchment areas or high drainage demands; smaller water passages 12 are used for situations with relatively smaller flow rates. This allows for reasonable diversion based on actual water flow conditions, avoiding problems such as poor drainage or water waste caused by unreasonable water passage 12 sizes.

[0045] It is important to emphasize that the aforementioned limitations on the location and size of the water passage 12 stem from several other reasons: 1) Hydraulics: A reasonable size and elevation design helps guide the water flow to form a stable flow pattern, reducing the generation of undesirable flow patterns such as eddies and backflows. A stable water flow can reduce the impact force on the walls of the water passage 12, reduce the frictional resistance between the water flow and the tunnel walls, improve water passage efficiency, and also extend the service life of the water passage 12. 2) Structural mechanics: The size and elevation of the water passage 12 must consider the various forces the structure will bear, including water pressure and earth pressure. Larger water passage 12s require thicker tunnel walls or stronger supporting structures to withstand external loads, ensuring the stability and safety of the structure. The setting of the tunnel bottom elevation also affects the buoyancy and foundation reaction forces at the bottom of the structure. For example, when the tunnel bottom elevation is low and the groundwater level is high, the structure of the water passage 12 needs to consider the influence of buoyancy and may need to take anti-buoyancy measures, such as installing anti-buoyancy piles, to ensure that the structure will not be damaged by buoyancy. 3) Prevention of backflow and siltation: By properly setting the bottom elevation of the water passage 12, backflow of external water bodies (such as river water, groundwater, etc.) into the water passage 12 can be prevented. For example, when the external water level is high, setting the bottom elevation of the water passage 12 higher than the current highest water level can effectively prevent backflow. At the same time, appropriate size and shape design also help reduce the accumulation of silt and other debris in the water passage 12, keeping the water passage 12 unobstructed, thereby reducing maintenance costs and difficulty.

[0046] In one embodiment, refer toFigure 3 As shown, the top of each of the multiple energy dissipation tanks 11 is equipped with a cover plate to prevent foreign objects from entering the energy dissipation tank 11 and affecting the sewage.

[0047] Here, as Figure 2 As shown, the first energy dissipation tank 111 is topped with a first cover plate 1111, the second energy dissipation tank 112 is topped with a second cover plate 1121, and the third energy dissipation tank 113 is topped with a second cover plate 1131. All three covers—first cover plate 1111, second cover plate 1121, and third cover plate 1131—are made of 10mm thick fiberglass plates. Each cover plate has a 500mm x 500mm opening hole for opening. The design of these covers effectively prevents people and other foreign objects from falling in and affecting the quality of the wastewater.

[0048] In one embodiment, refer to Figure 3 , Figure 2 As shown, the drainage section 2 includes a drainage unit and a metering unit; the drainage unit is connected to the energy dissipation section 1 and is used to discharge wastewater that enters the drainage unit after being dissipated by the energy dissipation section 1; the metering unit is installed in the drainage unit and is used to measure the flow rate of wastewater entering the drainage unit.

[0049] Here, as Figure 3 , Figure 2 As shown, the drainage section 2 includes a drainage unit and a metering unit. The drainage unit and the third energy dissipation tank 113 are connected through a third water passage 123, which can discharge and treat the sewage that enters the drainage unit after energy dissipation. The metering unit is installed in the drainage unit and can measure the flow rate of sewage entering the drainage unit.

[0050] In one feasible approach, refer to Figure 3 , Figure 2 As shown, the drainage unit includes a drainage channel 21 arranged in an inverted L shape, and the metering unit is installed inside the drainage channel 21.

[0051] Here, as Figure 3 , Figure 2 As shown, the drainage unit is a drainage ditch 21 arranged in an inverted L shape. The end of the drainage ditch 21 near the third energy dissipation tank 113 is connected to the third energy dissipation tank 113 through a third water passage 123. After the sewage loses its potential energy by passing through the third energy dissipation tank 113, it enters the drainage ditch 21 to achieve sewage discharge. It should also be noted that a water inlet pipe 4 can also be installed on the side of the drainage ditch 21. When the potential energy of the sewage is not very large, the sewage can be discharged directly through the water inlet pipe 4.

[0052] In one feasible approach, refer to Figure 3 , ​ As shown, the metering unit includes a Parshall flume 22 installed in the drainage ditch 21 and a flow meter 23 installed in the Parshall flume 22, which is used to measure the flow rate of sewage passing through the Parshall flume 22.

[0053] Here, the centerline of the Parshall flume 22 coincides with the centerline of the drainage ditch 21. The gap between the Parshall flume 22 and the drainage ditch 21 is filled with concrete, and the upper surface is smoothed. The inlet of the Parshall flume 22 is connected to the side wall and the bottom of the drainage ditch 21 by a 30° concrete slope. The flow meter 23 is installed at the inlet of the Parshall flume 22 to measure the amount of sewage passing through the Parshall flume 22. Since the sewage enters the Parshall flume 22 after potential energy is eliminated, the overall measurement result can be improved.

[0054] It should also be noted that the drainage section 2 is equipped with a 2mm thick 316L material plate to facilitate future cleaning and maintenance.

[0055] The implementation principle of this embodiment is as follows: In this embodiment, the wastewater discharge tank for wine enters the first energy dissipation tank 111 through the inlet pipe 3. The wastewater from the first energy dissipation tank 111 enters the second energy dissipation tank 112 through the first water passage 121. The wastewater from the second energy dissipation tank 112 enters the third energy dissipation tank 113 through the second water passage 122. The wastewater from the third energy dissipation tank 113 enters the drainage ditch 21 through the third water passage 123, thereby eliminating the potential energy of the wastewater. The wastewater entering the drainage ditch 21 is then measured by the flow meter 23 installed in the Parshall flume 22. After measurement, it is discharged through the drain pipe 5 installed in the drainage ditch 21, which facilitates the discharge of wastewater and improves the accuracy of wastewater volume statistics.

[0056] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
