Description

Technical Field

[0001] This utility model relates to the field of building water supply technology, specifically to a novel elevated water tank water supply device. Background Technology

[0002] In building water supply systems, elevated water tanks, as important secondary pressurization facilities, are widely used in multi-story and high-rise buildings. The traditional elevated water tank water supply mode usually adopts the following structure: municipal water is pressurized and transported to the elevated water tank on the roof through ground or underground pump rooms. For users on the middle and lower floors, the water is directly supplied after being depressurized by a pressure reducing valve from the tank outlet. For users on the upper floors, due to insufficient height difference with the water tank, a dedicated booster unit needs to be added to the roof pump room.

[0003] However, the existing water supply model has certain technical shortcomings:

[0004] First, high-rise booster units need to operate around the clock, especially during periods of low water usage (such as at night), which results in a waste of electricity. When the high-rise booster pump fails or there is a power outage, high-rise users will be completely without water, and there is a lack of emergency water supply mechanisms.

[0005] Second, the existing water supply system is a static pipeline when water is not in use, and static water supply pipelines are prone to bacterial growth (such as Legionella), while the existing water supply system lacks active circulation and purification capabilities.

[0006] In view of this, the present invention proposes a novel high-level water tank water supply device. Utility Model Content

[0007] This utility model proposes a novel high-level water tank water supply device, which solves the problem of energy waste caused by the continuous operation of high-level booster units in the prior art.

[0008] The technical solution of this utility model is as follows: A novel high-level water tank supply device includes a low-level water tank. The outlet end of the low-level water tank is connected to a high-flow water pump unit and a low-flow water pump unit arranged in parallel via a conduit. The outlet end of the high-flow water pump unit is connected to a main water supply pipe. The outlet end of the low-flow water pump unit is connected to a T-pipe. One end of the T-pipe is connected to the main water supply pipe, and the other end of the T-pipe is fixedly connected to a water supply pipe. The outlet end of the main water supply pipe is connected to the high-level water tank. The outlet end of the water supply pipe is connected to an auxiliary water supply pipe, which is connected to the high-level water tank. The outlet end of the water supply pipe is fixedly connected to a diversion pipe, and the outlet end of the diversion pipe is fixedly connected to a high-rise water supply pipe. The outlet end of the high-level water tank is provided with an emergency bypass pipeline system connected to the high-rise water supply pipe. The outlet end of the high-level water tank is also fixedly connected to a main water supply pipe, which is connected to high-rise water supply pipes, mid-rise water supply pipes, and low-rise water supply pipes at different heights.

[0009] Preferably, a first pressure reducing valve is fixedly connected to each of the high-rise water pipe, the middle-rise water pipe, and the low-rise water pipe, and a second pressure reducing valve is fixedly connected to the main water supply pipe.

[0010] Preferably, the emergency bypass pipeline system includes a bypass pipe, the inlet end of which is connected to an elevated water tank, and the outlet end of which is connected to a water pipe for high-rise buildings.

[0011] Preferably, a first electric valve is fixedly connected to the bypass pipe, and a check valve is fixedly connected to the outlet end of the first electric valve.

[0012] Preferably, the inlet end of the low-level water tank is provided with a return water pipeline system, the return water pipeline system includes a return water pipe, the inlet end of the return water pipe is connected to the outlet end of the main water supply pipe, and the outlet end of the return water pipe is connected to the low-level water tank.

[0013] Preferably, a disinfection and filtration device is fixedly connected to the return water pipe, a third pressure reducing valve is fixedly connected to the outlet end of the disinfection and filtration device, and a second electric valve is fixedly connected to the outlet end of the third pressure reducing valve.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. A high-flow water pump unit and a low-flow water pump unit are connected in parallel at the outlet of the low-level water tank. The high-flow water pump unit is used to quickly replenish water to the high-level water tank during peak water usage periods (such as daytime); the low-flow water pump unit is dedicated to low water usage periods (such as nighttime), and replenishes water at a low flow rate through the water supply pipe, thus avoiding the ineffective operation of the large unit.

[0016] 2. A liquid level sensor is fixed inside the high-level water tank and connected to the back-end terminal signal. The system monitors the water level in the tank in real time and automatically switches the water pump mode according to water demand (for example, starting the high-flow unit when the water level is low and using only the low-flow unit when the water level is stable), thereby optimizing energy consumption. The diameter of the water supply pipe is smaller than that of the main water supply pipe. Combined with the low-flow water pump unit, it can supply water efficiently under low load, greatly reducing standby power consumption.

[0017] 3. An emergency bypass pipeline system is installed at the outlet of the high-level water tank. In the event of a power outage or abnormality in the water supply pipeline, the first electric valve will automatically open, allowing water in the high-level water tank to flow directly into the high-rise water supply pipe (or even the ultra-high-rise water supply pipe) through the bypass pipe, providing temporary water supply. Combined with the main water supply pipe and the auxiliary water supply pipe (the small flow water pump unit is connected through a T-junction), the system provides daily water supply to the high-rise under normal conditions (the branch pipe at the outlet of the water supply pipe is directly connected to the high-rise water supply pipe), reducing the dependence on the main booster unit and thus reducing the probability of failure.

[0018] 4. The low-level water tank inlet is equipped with a return water pipeline system, including a return water pipe, disinfection and filtration equipment, a third pressure reducing valve, and a second electric valve. Water from the main water supply outlet flows back to the low-level water tank through the return water pipe, forming an active circulation to avoid water stagnation. The disinfection and filtration equipment sterilizes and filters the return water in real time, removing impurities and microorganisms. The third pressure reducing valve regulates the water pressure, and the second electric valve controls the flow rate to ensure efficient and safe circulation. The circulation system covers the main water supply pipe, high-rise water pipe, mid-rise water pipe, and low-rise water pipe. In conjunction with the pressure reducing valves (first pressure reducing valve and second pressure reducing valve), it ensures stable water pressure on each floor and further reduces stagnant water areas.

[0019] 5. The water pipes for high-rise, mid-rise, and low-rise buildings are all equipped with a first pressure reducing valve, and the main water supply pipe is equipped with a second pressure reducing valve to ensure stable water supply pressure for different floors. This improves user comfort and extends the life of the pipes. The system adopts a modular design, such as a T-junction connecting the small flow unit and the water supply pipe, which facilitates installation and upgrades. The liquid level sensor is linked with the back-end terminal to support remote monitoring and early warning, reducing operation and maintenance costs. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-5 As shown, this embodiment proposes a novel high-level water tank supply device, including a low-level water tank 1. The outlet end of the low-level water tank 1 is connected via a conduit to a high-flow water pump unit 2 and a low-flow water pump unit 3, which are arranged in parallel. The outlet end of the high-flow water pump unit 2 is connected to a main water supply pipe 4, and the outlet end of the low-flow water pump unit 3 is connected to a T-connector 31. One end of the T-connector 31 is connected to the main water supply pipe 4, and the other end of the T-connector 31 is fixedly connected to a water inlet pipe 6. The diameter of the water inlet pipe 6 is smaller than that of the main water supply pipe 4, and the outlet end of the main water supply pipe 4 is connected to... The system is equipped with a high-level water tank 5, and an auxiliary water supply pipe 61 is connected to the outlet end of the water supply pipe 6. The auxiliary water supply pipe 61 is connected to the high-level water tank 5. A diversion pipe 62 is fixedly connected to the outlet end of the water supply pipe 62. A high-rise water supply pipe 9 is fixedly connected to the outlet end of the high-level water tank 5. An emergency bypass pipeline system 13 connected to the high-rise water supply pipe 9 is provided at the outlet end of the high-level water tank 5. A main water supply pipe 8 is also fixedly connected to the outlet end of the high-level water tank 5. The main water supply pipe 8 is connected to the high-rise water supply pipe 9, the middle-level water supply pipe 10 and the low-rise water supply pipe 11 at different heights.

[0029] By starting the high-flow water pump unit 2, a large flow of water can be supplied to the main water supply pipe 4, thus achieving a large flow of water supply to the high-level water tank 5, which can guarantee the water demand during peak water usage periods. By using the low-flow water pump unit 3 to supply a small flow of water to the water supply pipe 6, the water supply pipe 6 can supply a small flow of water to the high-level water tank 5, which can automatically replenish water during off-peak water usage periods, thereby achieving efficient operation of the low-level water supply unit 24 / 7. The water supply pipe 6 is then connected to the high-rise residents through a small pipe, thus achieving daily water supply for the high-rise residents without the need for the high-level water supply unit.

[0030] Furthermore, a first pressure reducing valve 14 is fixedly connected to the high-rise water pipe 9, the mid-rise water pipe 10, and the low-rise water pipe 11, and a second pressure reducing valve 41 is fixedly connected to the main water supply pipe 4. The first pressure reducing valve 14 and the second pressure reducing valve 41 can reduce the water pressure, reduce the water pressure when using water, and ensure the inlet water pressure of the high-level water tanks of different floors and the water supply pressure of high-rise residents.

[0031] Furthermore, the emergency bypass pipeline system 13 includes a bypass pipe 131, the inlet end of which is connected to the high-level water tank 5, the outlet end of which is connected to the high-rise water pipe 7, a first electric valve 132 is fixedly connected to the bypass pipe 131, and a check valve 133 is fixedly connected to the outlet end of the first electric valve 132.

[0032] In the event of a power outage or water supply pipeline malfunction, the water inside the high-level water tank 5 is diverted into the bypass pipe 131 via the first electric valve 132, and then water is supplied to the high-rise water pipe 7 through the bypass pipe 131. This provides emergency water supply in the event of a power outage or water supply pipeline malfunction.

[0033] Furthermore, a return water pipeline system 12 is provided at the inlet end of the low-level water tank 1. The return water pipeline system 12 includes a return water pipe 121. The inlet end of the return water pipe 121 is connected to the outlet end of the main water supply pipe 8, and the outlet end of the return water pipe 121 is connected to the low-level water tank 1. A disinfection and filtration device 122 is fixedly connected to the return water pipe 121. A third pressure reducing valve 123 is fixedly connected to the pipeline at the outlet end of the disinfection and filtration device 122. A second electric valve 124 is fixedly connected to the outlet end of the third pressure reducing valve 123.

[0034] The water supply pipeline is circulated through the return water pipe 121. Disinfection and sterilization are carried out through the disinfection and filtration equipment 122. The second electric valve 124 can actively circulate the return water to avoid water stagnation. The disinfection and filtration equipment sterilizes and filters the return water in real time to remove impurities and microorganisms. The third pressure reducing valve regulates the water pressure, and the second electric valve controls the flow rate to ensure efficient and safe circulation. The circulation system covers the main water supply pipe, the water pipes of the upper floors, the water pipes of the middle floors, and the water pipes of the lower floors. With the help of pressure reducing valves (the first pressure reducing valve and the second pressure reducing valve), the water pressure of each floor is ensured to be stable, and dead water areas are further reduced.

[0035] Furthermore, a liquid level sensor is fixedly connected to the inner side of the high-level water tank 5. The liquid level sensor is connected to the back-end terminal signal. The liquid level sensor can monitor the water level of the high-level water tank 5 in real time. The system monitors the water level of the tank in real time and automatically switches the water pump mode according to the water demand (for example, when the water level is low, the large flow unit 2 is started, and when the water level is stable, only the small flow unit 3 is used), thereby optimizing energy consumption.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
