Description

Technical Field

[0001] The utility model relates to the technical field of water supply, in particular to a constant-pressure water supply energy-saving improvement device for high-rise buildings. Background Art

[0002] With the development of modern cities, the number of high-rise buildings is increasing, and providing these structures with a stable and reliable water supply has become a crucial issue. Currently, the traditional single-boost pump water supply method for high-rise buildings suffers from numerous serious drawbacks. A single booster pump struggles to maintain stable water pressure during operation. Due to its single operating mode, it cannot be flexibly adjusted based on actual water demand, often resulting in fluctuating water pressure. This unstable water pressure creates significant inconvenience for office building users, not only impacting daily work but also potentially damaging equipment with stringent water pressure requirements. In equipment such as water dispensers, unstable water pressure can affect their proper operation and even shorten their service life.

[0003] On the other hand, a single booster pump cannot adjust water pressure and cannot adapt to water supply needs at different times and with varying water usage. During peak usage periods, a single booster pump may not be able to provide sufficient water pressure in a timely manner, resulting in reduced or even no water flow on upper floors, seriously affecting office efficiency and employee work efficiency. During low usage periods, a single booster pump continues to operate at the same power, wasting energy and increasing operating costs.

[0004] Furthermore, with increasing demands for energy conservation and environmental protection, traditional water supply methods are experiencing poor energy efficiency. Single booster pumps, unable to intelligently adjust based on actual water usage, operate at a fixed power level, consuming significant amounts of energy while failing to achieve optimal water supply. In today's energy-constrained environment, finding a water supply solution that both ensures stable water supply and achieves energy conservation is crucial.

[0005] In summary, the traditional single booster pump water supply method can no longer meet the water supply needs of high-rise buildings. A new water supply device is urgently needed to solve problems such as unstable water pressure and energy waste. Utility Model Content

[0006] The purpose of this utility model is to provide a constant pressure water supply energy-saving improvement device for high-rise buildings. By combining a fixed-frequency booster pump and a variable-frequency booster pump, the water pressure and water supply volume are monitored in real time by a pressure sensor, and the intelligent control meter accurately controls the switching and operation of the booster pump according to the feedback signal to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A high-rise building constant-pressure water supply energy-saving improvement device is characterized by including a fixed-frequency booster pump, a variable-frequency booster pump, a pressure sensor, an intelligent control meter, and connecting pipes and valves. The fixed-frequency booster pump and the variable-frequency booster pump are used in combination and are both connected to the main pipeline. The fixed-frequency booster pump is usually activated when water pressure needs to be quickly increased to meet large water supply demands. It operates at a fixed frequency and can provide high pressure and flow in a short period of time. The variable-frequency booster pump can flexibly adjust its output power and frequency according to actual water usage, achieving energy savings while ensuring stable water pressure.

[0009] Pressure sensors installed on the main pipelines monitor the water pressure and water flow in the water supply pipelines in real time. Using high-precision detection elements, these sensors convert changes in water pressure into electrical signals, which are then transmitted to the intelligent control meter. This ensures that the intelligent control meter accurately understands the operating status of the water supply system, allowing it to make timely adjustments.

[0010] The intelligent control meter is located in the control room and communicates with the fixed-frequency booster pump, variable-frequency booster pump, and pressure sensors. It is the core control unit of the entire water supply system, receiving data from the pressure sensors to intelligently control the fixed-frequency booster pump and variable-frequency booster pump.

[0011] The intelligent control meter collects water supply and water pressure data through pressure sensors, controlling the switching of fixed-frequency and variable-frequency booster pumps. Based on real-time water demand and water pressure fluctuations, it automatically selects the most appropriate booster pump operating mode to achieve constant pressure water supply and energy savings.

[0012] When the pressure sensor detects a high water flow and the water pressure is below the set range, it sends a signal to the intelligent control meter, which activates the fixed-frequency booster pump to supply water. In this case, the fixed-frequency booster pump uses its high output power to quickly increase the water pressure to meet the high water flow demand.

[0013] When the pressure sensor detects that the water pressure is stable and within its set range, it sends a signal to the intelligent control meter, which stops the fixed-frequency booster pump and switches to the variable-frequency booster pump. The variable-frequency booster pump, with its flexible adjustment capabilities, maintains stable water pressure and prevents pressure fluctuations.

[0014] The variable frequency booster pump uses pressure feedback from the pressure sensor, controlled by an intelligent control meter, and its internal frequency converter controls its output frequency to ensure stable water pressure. The frequency converter adjusts the motor speed based on the pressure sensor signal, thereby varying the booster pump's output flow and pressure, achieving precise control of water pressure.

[0015] The intelligent control meter uses the access time to select the variable frequency booster pump to supply water at night. Since water consumption is lower at night, the variable frequency booster pump can run at a low power level, meeting the small water demand while maximizing energy conservation.

[0016] The intelligent control meter is connected to a display, which allows for manual operation. The display shows various water supply system parameters, such as water pressure, flow rate, and pump operating status. Users can use the display interface to set parameters and query faults on the intelligent control meter, improving the system's maintainability and ease of use.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Traditional water supply systems using a single booster pump often experience fluctuating water pressure in high-rise buildings, due to the inability to flexibly adjust water pressure. This often causes significant inconvenience for users. However, this new system utilizes a combination of fixed-frequency and variable-frequency booster pumps. Pressure sensors monitor water pressure and water supply in real time, and intelligent control meters precisely control the switching and operation of the booster pumps based on feedback signals, ensuring stable water pressure in high-rise buildings. This effectively prevents water pressure fluctuations during both peak and low water usage periods, providing users with a comfortable and reliable water environment.

[0019] Traditional single booster pumps continue to operate at a fixed power level even during periods of low water usage, resulting in significant energy waste. This device activates the fixed-frequency booster pump when water volume is high, rapidly increasing water pressure. Once the water pressure stabilizes, it switches to the variable-frequency booster pump, adjusting the output frequency based on actual water usage. During nighttime hours when water usage is low, only the variable-frequency booster pump is used, significantly reducing energy consumption. Actual testing has shown that this device can save up to 20% in electricity consumption, effectively reducing operating costs and aligning with current trends in energy conservation and environmental protection.

[0020] The intelligent control meter, through communication with pressure sensors, fixed-frequency booster pumps, and variable-frequency booster pumps, enables intelligent control of the entire water supply system. It automatically collects data on water supply volume and water pressure, and precisely controls the switching of booster pumps based on preset parameters and algorithms, without requiring human intervention. Furthermore, the display connected to the intelligent control meter allows for user-controlled operation, allowing users to monitor system operating status and adjust parameters at any time, improving system maintainability and ease of use.

[0021] This device can adapt to water supply demands at different times and with varying water usage. During peak usage periods, the fixed-frequency booster pump and the variable-frequency booster pump work together to ensure adequate water pressure and supply. During low-use periods and at night, the variable-frequency booster pump operates at low power, meeting low water demands while saving energy. This adaptability makes this device widely applicable to water supply systems in various high-rise buildings, making it highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be fully described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 As shown, a high-rise building constant pressure water supply energy-saving improvement device is characterized in that it includes a fixed frequency booster pump 1, a variable frequency booster pump 2, a variable frequency booster pump 3, an intelligent control meter 4 and connecting pipes and valves; the fixed frequency booster pump 1 and the variable frequency booster pump 2 are used in combination and are both connected to the main pipeline, the main pipeline is installed with a pressure sensor 3, the intelligent control meter 4 is placed in the control room, and is communicated with the fixed frequency booster pump 1, the variable frequency booster pump 2 and the pressure sensor 3.

[0026] The intelligent control meter 4 collects water supply and water pressure data through the pressure sensor 3, thereby controlling the fixed-frequency booster pump 1 and the variable-frequency booster pump 2 to switch working states.

[0027] When the pressure sensor 3 detects that the water supply is large and the water pressure is lower than the set range, the pressure sensor 3 feeds back a signal to the intelligent control meter 4 to start the fixed-frequency booster pump 1 to supply water.

[0028] When the pressure sensor 3 detects that the water pressure is stable and within the set range of the pressure sensor, the pressure sensor 3 feeds back a signal to the intelligent control meter 4 to control the fixed-frequency booster pump 1 to stop working and switch to the variable-frequency booster pump 2 to start.

[0029] The variable frequency booster pump 2 is controlled by the intelligent control meter 4 according to the pressure feedback from the pressure sensor 3, and the frequency converter 21 inside the variable frequency booster pump 2 controls its output frequency to ensure stable water pressure.

[0030] The intelligent control meter 4 uses the variable frequency booster pump 2 to supply water at night according to the access time.

[0031] The intelligent control meter 4 is connected to a display 41 , and manual operation can be performed through the display 41 .

[0032] The following are specific implementation methods for constant pressure water supply energy saving improvement devices in high-rise buildings:

[0033] First, install the equipment. Connect the fixed-frequency booster pump 1 and the variable-frequency booster pump 2 to the main pipeline according to the design requirements. Install a pressure sensor 3 at a suitable location on the main pipeline to accurately monitor water pressure changes. Place the intelligent control meter 4 in the control room and establish communication connections with the fixed-frequency booster pump 1, the variable-frequency booster pump 2, and the pressure sensor 3. Data transmission can be achieved through wired or wireless means.

[0034] During operation, the intelligent control meter 4 collects real-time data on water supply and water pressure via the pressure sensor 3. When the pressure sensor 3 detects a high water supply and a water pressure below the set range, it sends a signal back to the intelligent control meter 4. This signal then activates the fixed-frequency booster pump 1, which operates at a fixed frequency to rapidly increase the water pressure to meet the high-flow demand. When the pressure sensor 3 detects that the water pressure is stable and within the set range, it sends another signal back to the intelligent control meter 4. The intelligent control meter 4 stops the fixed-frequency booster pump 1 and switches to the variable-frequency booster pump 2. Based on the pressure feedback from the pressure sensor 3 and controlled by the intelligent control meter 4, the variable-frequency booster pump 2 adjusts its output frequency via the inverter 21 within the variable-frequency booster pump 2 to ensure stable water pressure.

[0035] Furthermore, the intelligent control meter 4 uses access time to determine nighttime hours. During nighttime hours when water demand is low, the variable frequency booster pump 2 is used to supply water, meeting the low water demand while also achieving energy savings. A display 41 connected to the intelligent control meter 4 allows for user control. Users can use the display 41 to view system operating status, set parameters, and perform fault detection operations, ensuring stable system operation and timely maintenance.
