[0002] Pump room water supply tank is a core component of secondary water supply facilities. It usually refers to a closed water storage device used to store and regulate water volume. It is commonly found in high-rise buildings, public facilities and other scenarios that require pressurized water supply. Its main function is to pressurize and supply domestic water, process water, water feature water and replenishment water. However, with long-term use, scale will adhere to the inner surface of the water supply tank, so it is necessary to clean it.

[0003] A water supply tank for a pumping station, with the existing publication number CN221193554U, includes a tank body, an inlet at the top of the tank body, an outlet at the bottom of the tank body, a cleaning mechanism on one side of the tank body, a sewage discharge assembly at the bottom of the tank body, a filter assembly on one side of the inlet of the tank body, a water level monitoring assembly on one side of the tank body, and a support assembly at the bottom of the tank body;

[0004] In summary, although it can automatically scrape and clean the inner wall of the tank, its sewage discharge structure has defects. When sewage is discharged, the entire water supply system needs to be shut down, and normal water supply and drainage cannot be carried out. Secondly, the water in the tank must be drained before sewage discharge can be carried out, which makes the entire sewage discharge work inconvenient. Utility Model Content

[0031] Reference Figure 1-4 This utility model provides an embodiment of a water supply tank, including a water storage tank 1. A support 2 is fixedly connected to the bottom of the water storage tank 1, and an inner cavity 3 is provided inside the water storage tank 1. The inner cavity 3 is a water storage space. A water inlet pipe connector 4 is provided at the top of the water storage tank 1. The water inlet pipe connector 4 can be easily connected to a pipeline to replenish water to the inner cavity 3. The water storage tank 1 is equipped with a level gauge and an overflow pipe, which are conventional methods and will not be described in detail here. A motor 5 is fixedly connected to the top of the water storage tank 1. The motor 5 can be of model RV75-20-Y. A cleaning frame 6 is fixedly connected to the output end of the motor 5. The cleaning frame 6 is located in the inner cavity 3, and the cleaning frame 6 is slidably fitted with the inner wall and bottom of the inner cavity 3. The motor 5 drives the cleaning frame 6 to rotate, which can scrape and clean the inner wall of the inner cavity 3, remove the adhering scale and impurities, and ensure the cleanliness of the water. A water outlet pipe 7 is provided at the bottom of the water storage tank 1, which is the drainage position.

[0032] A fixed pipe 10 is connected to the outlet pipe 7. A switch valve 11 is installed on the fixed pipe 10, which controls the opening and closing of the flow in the fixed pipe 10. A movable pipe 12, which is a flexible hose, is installed below the fixed pipe 10. A one-way valve 13 is installed on the movable pipe 12 to prevent backflow of water. A water supply pipe 15 is connected to the movable pipe 12, which is the water supply line to the water tank. A filter and drainage mechanism 9 is installed between the fixed pipe 10 and the movable pipe 12. This mechanism allows for the stable filtration of scale and impurities deposited after cleaning the water tank, purifying the water for normal use. It also serves as a filter for daily water supply. The structure includes two sets of fixed pipes 10, switch valves 11, movable pipes 12, and filter drainage mechanism 9. The two fixed pipes 10 are connected to the water outlet pipe 7 via a tee connector 8, and the two movable pipes 12 are connected to the water supply pipe 15 via a tee connector 14. The arrangement of the two sets of pipes and the filter drainage mechanism 9 allows one pipe to be closed and the filter drainage mechanism 9 to be cleaned during cleaning, while the other pipe can continue to supply water. Similarly, the positions of the two pipes can be switched to clean the filter drainage mechanism 9 in the other pipe. This enables convenient drainage work, which does not require the complete draining of water from the storage tank and allows for uninterrupted cleaning, greatly improving the convenience of cleaning work.

[0033] The filtration and sewage discharge mechanism 9 includes a fixed cylinder 91 and a connecting cylinder 92, which are respectively connected to the fixed pipe 10 and the movable pipe 12. A filter chamber 93 is provided between the fixed cylinder 91 and the connecting cylinder 92. A filter element cylinder 94 is nested inside the filter chamber 93. From top to bottom, the filter element cylinder 94 is provided with a first filter screen 95, a second filter screen 96, and an activated carbon filling layer 97. The first filter screen 95 can be made of stainless steel mesh with a pore size of 0.25mm. The second filter screen 96 is a filter membrane with a pore size of 5-20μm. A connecting mechanism is provided between the fixed cylinder 91 and the connecting cylinder 92. The first filter screen 95 can filter some small mud and sand, the second filter screen 96 can filter some small impurities in the water, and the activated carbon filling layer 97 can adsorb and purify the water, thus completing the filtration and purification work. The connecting mechanism not only allows the fixed cylinder 91 and the connecting cylinder 92 to be stably connected together to form a stable filtration and sewage discharge mechanism 9, but also allows for easy disassembly and cleaning of the internal structure.

[0034] A fixing notch 98 is provided at the junction of the fixing cylinder 91 and the connecting cylinder 92, and a sealing ring 99 is nested inside the fixing notch 98. This structure can ensure the tightness of the connection between the fixing cylinder 91 and the connecting cylinder 92.

[0035] The connecting mechanism includes a threaded connecting block 910 fixed to the outer surface of the fixed cylinder 91 and a fixed block 911 fixedly connected to the outer surface of the connecting cylinder 92. A connecting sleeve 912 is nested and slidably connected to the outer surface of the connecting cylinder 92 and sleeved on the fixed block 911. The inner surface of the connecting sleeve 912 is provided with a threaded inner groove 913. The threaded connecting block 910 and the threaded inner groove 913 are threadedly connected. The thread type on the threaded connecting block 910 and the threaded inner groove 913 adopts the Spilock self-locking thread type, which can ensure the stability of the structure installation. During operation, the fixed cylinder 91 and the connecting cylinder 92 are connected, and the connecting sleeve 912 is slidably sleeved on the outside of the fixed block 911. The connecting sleeve 912 is rotated so that the threaded inner groove 913 and the threaded connecting block 910 are threaded together, thus completing the positioning and installation of the structure. Similarly, it can also be easily disassembled during operation.

[0036] Working principle: When using the water supply tank, the cleaning frame 6 is driven by the motor 5 to rotate, and the cleaning frame 6 can scrape the inner wall of the inner cavity 3, thereby cleaning the water storage tank 1. Scale and other impurities follow the water flow through the outlet pipe 7 and the fixed pipe 10 into the filter and sewage discharge mechanism 9, thus filtering out the dirt. When the filter and sewage discharge mechanism 9 needs to be cleaned, close the switch valve 11 on the left fixed pipe 10, open the connecting mechanism, separate the connecting cylinder 92 from the fixed cylinder 91, and take out the filter cartridge 94 for easy cleaning or replacement. While the left filter and sewage discharge mechanism 9 is being cleaned and discharged, the right pipeline can continue to supply water normally. Reinstall the cleaned filter cartridge 94, and then reassemble the connecting cylinder 92 and the fixed cylinder 91 to complete the cleaning of the left filter and sewage discharge mechanism 9. Open the switch valve 11 on the left fixed pipe 10 and close the switch valve 11 on the right fixed pipe 10, and operate in the same way to clean the right filter and sewage discharge mechanism 9. This allows for convenient cleaning of the structure.

[0037] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
