The following is a detailed description through specific embodiments.

[0045] See also Figure 1 , Figure 1 The structure diagram of a water storage and drainage device provided by the utility model is shown. In one embodiment of the utility model, the water storage and drainage device may include a recovery tank 100, a pre-set water tank 200, an external drainage pipe 300 and a main drainage pipeline 400. Among them, the recovery tank 100 may be, for example, an accident water tank in a factory, which can be used to recover and store abnormal water quality generated in an industrial production process. The pre-set water tank 200 may be arranged above the recovery tank 100. The pre-set water tank 200 may be used to inject water into the main drainage pipeline 400, thereby causing a siphon effect. The external drainage pipe 300 may be arranged on the side of the recovery tank 100. The external drainage pipe 300 may be connected to the sewage discharge pipe of the factory. The main drainage pipeline 400 may be provided with a plurality of ports, and the main drainage pipeline 400 may be connected between the main drainage pipeline 400 and the external drainage pipe 300. The pre-set water tank 200 and the main drainage pipeline 400 may be connected. In this embodiment, the main drainage pipeline 400 may be provided with at least three ports, namely, a main water inlet 410, a main water outlet 420, and a water injection port 430. The main water inlet 410 may be disposed in the recovery tank 100, and the main water outlet 420 may be connected to the external drainage pipe 300. The height of the main water inlet 410 may be higher than the height of the main water outlet 420. The pre-set water pool 200 is connected to the water injection port 430, and the height of the pre-set water pool 200 is higher than the height of the main drainage pipeline 400. The pre-set water pool 200 may be used to inject water into the main drainage pipeline 400, thereby causing a siphon effect.

[0046] See also Figure 1 In one embodiment of the present invention, the main drainage pipeline 400 further includes a water injection valve 440 and a main drainage valve 450. The water injection valve 440 is disposed at the water injection end 430. The main drainage valve 450 is disposed at the main water outlet end 420. In this embodiment, the height of the main drainage valve 450 may be flush with the height of the main water inlet end 410, or the height of the main drainage valve 450 may be lower than the height of the main water inlet end 410.

[0047] See also Figure 1 In one embodiment of the utility model, the water storage and drainage device further includes a collection tank 500 and an auxiliary drainage pipeline 600. The collection tank 500 may be arranged on the side of the recovery tank 100. In this embodiment, the collection tank 500 and the external drainage pipe 300 may be located on the same side of the recovery tank 100, and the collection tank 500 may be located between the recovery tank 100 and the external drainage pipe 300. The collection tank 500 may be a rainwater collection tank in a factory, which may be used to store collected rainwater or water stored in an accident pool. The auxiliary drainage pipeline 600 may be provided with at least two ports, namely an auxiliary water inlet end 610 and an auxiliary water outlet end 620. The auxiliary water inlet end 610 may be arranged in the recovery tank 100, and the auxiliary water inlet end 610 may be arranged in the collection tank 500. In this embodiment, the auxiliary drainage pipeline 600 is connected to the main drainage pipeline 400.

[0048] See also Figure 1 In one embodiment of the present invention, the auxiliary drainage pipeline 600 further includes an auxiliary drainage valve 630. The auxiliary drainage valve 630 may be disposed at the auxiliary water outlet 620. In this embodiment, the height of the auxiliary drainage valve 630 may be flush with the height of the main water inlet 410, or the height of the auxiliary drainage valve 630 may be lower than the height of the main water inlet 410.

[0049] See also Figure 2 , Figure 2 The schematic diagram shows the water filling state of the main drainage pipeline 400 in the present invention. In one embodiment of the present invention, when the water in the recovery tank 100 is at a high water level and needs to be drained, first, the water filling valve 440, the main drainage valve 450 and the auxiliary drainage valve 630 are closed. Then, a sufficient amount of water is poured into the pre-set water tank 200. Next, the water filling valve 440 is opened so that the water in the pre-set water tank 200 is poured into the main drainage pipeline 400 and the auxiliary drainage pipeline 600. When the main drainage pipeline 400 and the auxiliary drainage pipeline 600 are completely filled with water, the water filling valve 440 is closed.

[0050] See also Figure 3 , Figure 3It is a schematic diagram showing the rapid drainage state of the main drainage pipeline 400 in the utility model. It should be noted that the siphon effect refers to the fact that due to the effect of liquid gravity and atmospheric pressure, the liquid can flow from a high place through a curved pipe to a low place. Even if the liquid level at the high place is higher than the low place, as long as the liquid columns at both ends are connected and the highest point exceeds the atmospheric pressure action point of the liquid surface, continuous flow can be achieved until the liquid levels at both ends are level or the gas in the pipe prevents the liquid from continuing to flow out. Therefore, when the main drainage pipeline 400 and the auxiliary drainage pipeline 600 are completely filled with water, the main drainage valve 450 can be opened to discharge the water in the recovery pool 100 into the external drainage pipe 300 through the siphon effect. Alternatively, the auxiliary drainage valve 630 can be opened to discharge the water in the recovery pool 100 into the collection pool 500 through the siphon effect. In this embodiment, the main drainage valve 450 and the auxiliary drainage valve 630 can also be opened at the same time to achieve rapid discharge of the stored water in the recovery pool 100.

[0051] See also Figure 4 , Figure 4 The schematic diagram of the main drainage pipeline 400 in the utility model is shown as a drainage stop state. In one embodiment of the utility model, after the water in the recovery tank 100 is discharged through the main drainage pipeline 400 and / or the auxiliary drainage pipeline 600, the liquid level of the recovery tank 100 gradually decreases. When the liquid level of the recovery tank 100 drops to the same height as the main water inlet end 410, air will enter the main drainage pipeline 400 from the main water inlet end 410, destroying the vacuum state in the main drainage pipeline 400. At this time, the rapid drainage of the main drainage pipeline 400 will stop, and the main drainage valve 450 and the auxiliary drainage valve 630 can be closed.

[0052] See also Figure 5 , Figure 5 The figure shows the drainage state of the auxiliary drainage pipeline 600 in the present invention. In one embodiment of the present invention, after a period of sewage and rainwater collection, the water level in the recovery tank 100 will rise. At this time, the auxiliary drainage valve 630 can be opened to achieve a small flow of drainage from the recovery tank 100 to the collection tank 500.

[0053] In summary, the utility model proposes a water storage and drainage device, which can realize the rapid drainage of accident pools and rainwater pools by applying the siphon effect, and can also control the liquid level in the pool within the required range. The utility model has the advantages of simple and reliable structure, convenient and flexible use, and solves the problem of excessive drainage energy consumption when the water level of accident pools and rainwater pools in the factory is deep. The operator can choose an effective drainage method according to the depth of the water level, thereby reducing the drainage energy consumption. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
