Technical Field

[0001] This utility model relates to the field of municipal water storage technology, and in particular to a water storage and drainage device. Background Technology

[0002] In the field of water supply and drainage engineering, water storage and regulation structures play a crucial role, especially in dealing with fluctuations in water flow, overload of sewage pipe networks, and pressure on rainwater discharge.

[0003] Traditional water storage and regulation methods use gravity flow for water intake and pressure boosting for water output. This method relies entirely on pressure boosting for water output and uses gravity for water intake. Although using gravity saves energy, it results in the storage space of the water tank above the highest point of the pipe network being unusable, leading to a waste of the upper structure volume of the water tank.

[0004] Therefore, in order to solve the problem of wasted water storage tank volume, a new type of water storage and drainage device is proposed. Utility Model Content

[0052] Example 2,

[0053] A detection component is applied to the water storage and drainage device in Embodiment 1;

[0054] Specifically, the detection component includes multiple radar level gauges 3, which are respectively installed on the top of the pipeline inspection well 4, the pump pit 2 and the water storage tank 1. The radar level gauges 3 are used to observe changes in water level.

[0055] In actual use, pipeline inspection wells are part of the external pipeline network system;

[0056] When the external pipeline system does not require water storage and drainage, the water storage tank 1 is in an unloaded working condition. The equipment in the closed state under this working condition includes the first attached gate 6, the second attached gate 7, the submersible pump 8, the inlet butterfly valve 9, and the outlet butterfly valve 11.

[0057] When the external pipeline system needs to store and drain water, when the radar level gauge 3 at the top of the pipeline inspection well 4 detects that the water level in the pipeline inspection well 4 has risen to the water storage start-up level, the first attached gate 6 and the second attached gate 7 are opened. At this time, the water storage tank 1 is in gravity water intake mode, and the water in the pipeline inspection well 4 flows into the pump pit 2 and the water storage tank 1 by gravity through the liquid level difference. Under this mode, the equipment in the open state is the first attached gate 6 and the second attached gate 7, and the equipment in the closed state is the submersible pump 8, the inlet butterfly valve 9, and the outlet butterfly valve 11.

[0058] Under gravity-fed water intake conditions, the liquid levels in pump pit 2 and water storage tank 1 continue to rise. When the radar level gauge 3 at the top of water storage tank 1 detects that the liquid level in water storage tank 1 has risen to the same level as the liquid level in pipeline inspection well 4, the second wall gate 7 is closed and the submersible pump 8 and inlet butterfly valve 9 are opened. At this time, water storage tank 1 is under pressure-fed water intake conditions. The water in pump pit 2 flows into water storage tank 1 through pressure boosting. Under these conditions, the equipment in the open state includes the first wall gate 6, submersible pump 8, and inlet butterfly valve 9, while the equipment in the closed state includes the second wall gate 7 and outlet butterfly valve 11.

[0059] Under pressure inlet conditions, the liquid level in storage tank 1 continuously rises. When the radar level gauge 3 at the top of storage tank 1 detects that the liquid level in storage tank 1 has risen to the designed maximum water level, the submersible pump 8 and the inlet butterfly valve 9 are shut off. When the radar level gauge 3 at the top of pump pit 2 detects that the liquid level in pump pit 2 has risen to be level with the liquid level in the pipeline inspection well 4, the first wall-mounted gate 6 is closed. At this time, pump pit 2 and storage tank 1 are in full-load operation. The equipment in the closed state under this condition includes the first wall-mounted gate 6, the second wall-mounted gate 7, the submersible pump 8, the inlet butterfly valve 9, and the outlet butterfly valve 11.

[0060] When the radar level gauge 3 at the top of the pipeline inspection well 4 detects that the water level in the pipeline inspection well 4 has dropped to the drainage start-up water level, the first attached gate 6 and the second attached gate 7 are opened. At this time, the water storage tank 1 is in gravity discharge mode. The water in the pump pit 2 and the water storage tank 1 is discharged to the pipeline inspection well 4 by gravity through the liquid level difference. The equipment in the open state under this mode is the first attached gate 6 and the second attached gate 7, and the equipment in the closed state is the submersible pump 8, the inlet butterfly valve 9, and the outlet butterfly valve 11.

[0061] Under gravity discharge conditions, when the radar level gauge 3 at the top of the water storage tank 1 detects that the water level in the water storage tank 1 has dropped to the same level as the water level in the pipeline inspection well 4, the first wall gate 6 is closed and the submersible pump 8 and the outlet butterfly valve 11 are opened. At this time, the water storage tank 1 is in pressure discharge conditions, and the water in the pump pit 2 is discharged to the pipeline inspection well 4 through pressure boosting. Under these conditions, the equipment in the open state includes the second wall gate 7 and the submersible pump 8, and the outlet butterfly valve 11. The equipment in the closed state includes the first wall gate 6 and the inlet butterfly valve 9.

[0062] Under pressure discharge conditions, when the radar level gauge 3 at the top of water storage tank 1 detects that the water level in water storage tank 1 has dropped to the design minimum level, the second wall-mounted gate 7, submersible pump 8, and outlet butterfly valve 11 are closed. At this time, water storage tank 1 is in no-load condition. The equipment in the closed state under this condition includes the first wall-mounted gate 6, the second wall-mounted gate 7, the submersible pump 8, the inlet butterfly valve 9, and the outlet butterfly valve 11.

[0063] Furthermore, by setting up a water storage tank 1 and a pump pit 2 on the side of the pipeline inspection well 4, this design avoids the limitation of gravity flow water storage height, thereby improving the volume utilization rate of the water storage tank 1 and avoiding the waste of water storage space in the water storage tank 1.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
