Description

Technical Field

[0001] This invention relates to the field of emergency water supply vehicle technology, and in particular to a new energy relay booster water supply vehicle and water supply method. Background Technology

[0002] When dealing with sudden water outages caused by burst water pipes in urban water supply networks or equipment failures in community pump rooms, the commonly used emergency water supply methods mainly rely on large fuel-powered water tankers or emergency water supply vehicles driven by onboard generator sets.

[0003] Large fuel-powered water tankers, due to their large chassis size, have difficulty entering narrow internal roads and underground parking lots in older residential areas, resulting in excessively long distances between water collection points and users, making water supply extremely inconvenient. Furthermore, their limited capacity for a single trip cannot meet long-term, large-scale temporary water supply needs.

[0004] While water supply trucks equipped with generator sets and booster pumps can extend water supply time by connecting to external pipe networks, their structure has significant drawbacks. These vehicles typically use fuel-powered chassis and are equipped with independent diesel generator sets to power the water pumps. Diesel generator sets generate considerable noise during operation, especially at night, causing serious disturbance to residents; furthermore, their exhaust emissions contribute to environmental pollution, contradicting energy conservation and environmental protection trends. In addition, fuel-powered vehicles are subject to traffic restrictions in some urban areas, limiting their operational range.

[0005] Therefore, there is an urgent need for an emergency water supply equipment that has better maneuverability, lower operating noise, is energy-saving and environmentally friendly, and can provide continuous water supply for a long time.

[0006] The above background information is provided only to aid in understanding the concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0007] The purpose of this invention is to provide a new energy relay booster water supply vehicle and water supply method to solve the problems existing in the prior art, with better passability, lower operating noise, energy saving and environmental protection, and the ability to achieve long-term continuous water supply.

[0008] To achieve the above objectives, the present invention provides the following solution: A new energy relay booster water supply vehicle includes: The new energy chassis has its own power battery and an external discharge interface for outputting electrical energy. A voltage inverter system is installed on the new energy chassis and electrically connected to the external discharge interface to convert the electrical energy of the power battery into alternating current. The water supply equipment group is installed on the new energy chassis and electrically connected to the voltage inverter system, and is powered by the voltage inverter system; The water supply equipment group includes at least one booster pump, an inlet pipe, and an outlet pipe. The inlet pipe is used to connect to an external water source, and the outlet pipe is used to connect to the user's water supply network. The booster pump is used to pressurize the water from the external water source and then deliver it to the user's water supply network through the outlet pipe.

[0009] In an exemplary embodiment, the new energy chassis is a hybrid chassis with a cargo box mounted on it, and the voltage inverter system and the water supply equipment group are both arranged inside the cargo box.

[0010] In one exemplary embodiment, the voltage inverter system includes a power collection gun, an inverter body, and a control panel; the input end of the power collection gun is pluggably connected to the external discharge interface, and the output end is connected to the input end of the inverter body; the output end of the inverter body is used to supply power to the water supply equipment group; the control panel is communicatively connected to the inverter body and is used to control and monitor the voltage inverter process.

[0011] In an exemplary embodiment, the water supply equipment group includes two or more booster pumps, each of which integrates a variable frequency motor. The booster pumps are connected in parallel, and the inlet ends of the booster pumps are all connected to the inlet pipeline, and the outlet ends of the booster pumps are all connected to the outlet pipeline.

[0012] In one exemplary embodiment, the system further includes a control system, which includes an inlet pressure detection device and an inlet flow detection device disposed on the inlet pipe, and an outlet pressure detection device disposed on the outlet pipe; the control system is communicatively connected to each of the variable frequency motors and each detection device, and is used to adjust the speed and start / stop of the variable frequency motors according to the signals fed back by the inlet pressure detection device or the outlet pressure detection device.

[0013] In one exemplary embodiment, a flow stabilizing tank is also provided on the inlet pipe to suppress water pressure fluctuations of the external water source; a pressure stabilizing tank is also provided on the outlet pipe to suppress water pressure fluctuations of the outlet pipe.

[0014] In one exemplary embodiment, the system further includes a water intake pump powered by the voltage inverter system, the water intake pump being configured to relocatably draw water from an external water source over a long distance and deliver water to the inlet pipe of the water supply equipment group.

[0015] In an exemplary embodiment, the cargo box is provided with a rainproof enclosure that encloses the voltage inverter system and the water supply equipment assembly; the rainproof enclosure is provided with an air inlet window and an air outlet window for air circulation and heat dissipation inside and outside the rainproof enclosure.

[0016] In one exemplary embodiment, the system further includes a main control system cabinet disposed on the side of the rainproof enclosure. The main control system cabinet integrates a main power switch and a water supply equipment operation panel. The main power switch is connected in series between the voltage inverter system and the water supply equipment group to control the power supply on / off.

[0017] This invention also provides a water supply method using the aforementioned new energy relay booster water supply vehicle, applicable to emergency water supply, characterized by comprising the following steps: The aforementioned new energy relay booster water supply vehicle was driven and parked near the user's water supply network access point; The inlet pipe of the water supply equipment group installed on the water supply vehicle is connected to an external continuous water source, and the outlet pipe of the water supply equipment group is connected to the user's water supply network, thereby constructing a relay water supply link from the external continuous water source through the water supply equipment group to the user's water supply network. The voltage inverter system installed on the water supply vehicle is activated, which draws DC power from the power battery through the external discharge interface of the new energy chassis and converts it into AC power to supply the water supply equipment group. The booster pump in the water supply equipment group operates under the drive of the AC power, pressurizes the water from the external continuous water source, and continuously delivers it to the user's water supply network through the outlet pipeline, thereby realizing relay booster water supply.

[0018] The present invention achieves the following technical effects compared to the prior art: 1. High mobility and wide operating coverage: By adopting a new energy chassis, the chassis is relatively compact and small, which can reach narrow areas such as roads and underground parking lots in old residential areas that traditional large water tankers cannot reach. It can operate directly near the user's pipeline network, which greatly improves the convenience and timeliness of emergency water supply and solves the problems of large vehicles being difficult to reach and long water supply distances.

[0019] 2. Low operating noise and energy saving: The water supply equipment is driven directly by the power battery of the new energy chassis through a voltage inverter system, completely eliminating the need for a separate diesel generator set in traditional solutions. This fundamentally eliminates the high-decibel noise generated by the generator set, solving the prominent problem of disturbing residents during nighttime operations. At the same time, the chassis itself can achieve zero-emission operation in pure electric mode, and is even more efficient and cleaner in fuel mode, significantly reducing noise and exhaust pollution to the living environment of residents.

[0020] 3. Capable of long-term relay water supply with rapid restoration: In this solution, the inlet pipe of the water supply equipment group is used to connect to external continuous water sources such as fire-fighting pipelines around the community, while the outlet pipe is directly connected to the community's water supply network, serving as a "relay booster." This structure no longer relies on the limited-capacity water tank carried by the vehicle itself. As long as the external water source is uninterrupted, it can achieve uninterrupted, long-term continuous water supply, restoring the community's normal water supply pressure in a very short time, thus solving the fundamental problems of limited capacity and short supply duration of traditional water tankers.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The purpose of this invention is to provide a new energy relay booster water supply vehicle and water supply method to solve the problems existing in the prior art, with better passability, lower operating noise, energy saving and environmental protection, and the ability to achieve long-term continuous water supply.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1 Please refer to Figures 1 to 5 This embodiment provides a new energy relay booster water supply vehicle, including a new energy chassis 1, a voltage inverter system 2, and a water supply equipment group 3.

[0027] The new energy chassis 1 is equipped with its own power battery and an external discharge interface for outputting electrical energy to external devices. This external discharge interface is a standardized power supply port originally configured on the chassis, capable of drawing out the DC power stored in the power battery. This vehicle utilizes this interface to directly draw energy from the chassis's power battery to drive the onboard work equipment, thereby eliminating the need for a separate diesel generator set typically found on traditional emergency water supply vehicles. The resulting benefits are that the noise source during vehicle operation is completely eliminated, causing virtually no disturbance to residents in noise-sensitive environments such as residential areas, while also eliminating exhaust fumes from the generator set, making emergency water supply operations more energy-efficient and environmentally friendly.

[0028] The voltage inverter system 2 is mounted on the new energy chassis 1 and electrically connected to the external discharge interface. This voltage inverter system 2 converts the DC power output from the power battery into AC power to meet the AC power supply requirements of the electrical devices in the water supply equipment group 3. In one feasible implementation, the inverter circuit inside the voltage inverter system 2 can use a mature inverter topology based on IGBT or SiC power devices. Such circuit topologies are existing technologies, and those skilled in the art can directly select and configure them according to actual power level requirements; further details are omitted here.

[0029] The water supply equipment group 3 is also mounted on the new energy chassis 1 and is electrically connected to the voltage inverter system 2, which provides power to it with AC power output from the voltage inverter system 2. The water supply equipment group 3 includes at least one booster pump 4, an inlet pipe 5, and an outlet pipe 6. The inlet pipe 5 connects to an external water source 7, which can be a municipal fire pipeline, a large water tanker, or a long-distance natural water body obtained through the water intake pump 16. The outlet pipe 6 connects to the user's water supply network 8, specifically by connecting to the pump room storage tank of the target community, the front-end pipeline of the secondary water supply equipment, or directly to the building's main water supply pipeline. The booster pump 4 is connected between the inlet pipe 5 and the outlet pipe 6 to pressurize the water from the external water source 7 and deliver it to the user's water supply network 8 via the outlet pipe 6.

[0030] During emergency water supply operations, the new energy chassis 1 is driven to the work location. Utilizing its compact and agile design, it can directly enter narrow areas such as internal roads or underground parking lots within the community, bringing the water supply equipment group 3 as close as possible to the access point of the user's water supply network 8. The inlet pipe 5 is connected to the external water source 7, and the outlet pipe 6 is connected to the user's water supply network 8. The voltage inverter system 2 is activated, drawing power from the chassis's external discharge interface and converting it to AC power to supply the booster pump 4. The booster pump 4 draws water from the external water source 7, pressurizes it, and then injects it into the user's water supply network 8 through the outlet pipe 6, thus restoring the community's normal water supply pressure through this relay-pressurized water supply method.

[0031] The core of this solution lies in using the power battery of the new energy chassis 1 directly as a power source through the voltage inverter system 2, combined with the water supply equipment group 3 that can continuously draw water from an external water source, to form a vehicle-mounted system capable of long-term continuous pressurized water supply. This substantially solves the problems of traditional water tankers being unable to supply water for extended periods due to the limited capacity of their own water tanks, and the high noise and emissions of traditional generator-driven water supply vehicles. Since it no longer relies on the limited volume water tank carried by the vehicle, uninterrupted water supply can be achieved as long as the external water source 7 is uninterrupted; at the same time, by using the chassis's own electric power drive, the entire vehicle operation does not require a separate engine or generator set, achieving quiet, zero-emission operation while saving valuable load and space resources on the chassis to accommodate larger-scale water supply equipment group 3 or more accessories.

[0032] In this embodiment, the new energy chassis 1 adopts a hybrid chassis. This chassis combines pure electric drive and range-extended fuel-assisted drive capabilities. In pure electric mode, it is powered by the power battery and produces no exhaust emissions. When the battery is low, the range extender can generate electricity to supplement the power, giving the vehicle an extended range and continuous operating capability. Actual calculations show that in hybrid mode, it can achieve more than 24 hours of full-load water supply operation, fully covering the needs of most water outage repair periods. In addition, this chassis complies with the registration policy for new energy special vehicles and can be equipped with a hybrid green license plate. It also has traffic rights in some central urban areas where there are restrictions on the use of fuel vehicles, further expanding the coverage of emergency water supply operations.

[0033] The new energy chassis 1 is equipped with a cargo box 9, and the voltage inverter system 2 and water supply equipment group 3 are both arranged inside the cargo box 9. The cargo box 9 provides physical protection for the internal equipment and also provides a structural foundation for pipeline layout, making the vehicle equipment highly integrated and compactly arranged.

[0034] The voltage inverter system 2 includes a power take-up gun 10, an inverter main unit, and a control panel. The input terminal of the power take-up gun 10 is pluggably connected to the external discharge interface of the chassis. During operation, the power take-up gun 10 is inserted into the external discharge interface to complete the electrical connection, making operation convenient. After operation, the power take-up gun 10 is unplugged without affecting the normal driving function of the chassis. The output terminal of the power take-up gun 10 is connected to the input terminal of the inverter main unit via a cable, and the inverter main unit internally performs the DC-to-AC conversion. The output terminal of the inverter main unit is used to provide AC power that meets the voltage and frequency requirements of the water supply equipment group 3. The control panel is connected to the inverter main unit via a communication line. Operators can monitor parameters such as input voltage, output voltage, output current, and system operating status through the control panel, and can also operate the inverter to start and stop.

[0035] In a preferred embodiment, the water supply equipment group 3 includes two or more booster pumps 4, each of which integrates a variable frequency motor. The variable frequency motor and the booster pump 4 are integrated into a compact, single-unit structure, with a single variable frequency motor directly driving one booster pump 4, reducing the pump group's size and simplifying the transmission structure. The multiple booster pumps 4 are connected in parallel, meaning that the inlet of each pump is connected to the inlet pipe 5, and the outlet of each pump is connected to the outlet pipe 6. This parallel connection allows multiple pumps to operate simultaneously to increase the total water supply flow, and also allows the remaining pumps to continue supplying water if one pump fails or requires maintenance, thereby improving system redundancy and reliability.

[0036] The control system includes an inlet water pressure detection device 11 and an inlet water flow detection device 12 installed on the inlet water pipe 5, and an outlet water pressure detection device 13 installed on the outlet water pipe 6. The inlet water pressure detection device 11 and the inlet water flow detection device 12 are used to sense the water supply pressure and flow rate of the external water source 7 in real time, while the outlet water pressure detection device 13 is used to sense the water supply pressure on the side leading to the user's pipe network in real time. All of the above detection devices can be commercially available industrial sensor products such as pressure transmitters and electromagnetic flow meters; their selection and installation methods are conventional techniques in this field and will not be elaborated upon.

[0037] The control system is connected to each variable frequency motor and each detection device via a communication bus to form a closed-loop control circuit. Its control logic is as follows: When the inlet water pressure detection device 11 or the inlet water flow detection device 12 detects low inlet water pressure or insufficient flow, it indicates a decrease in the water supply capacity of the external water source 7. The control system automatically lowers the operating frequency of each booster pump 4 variable frequency motor to adapt to the incoming water capacity while ensuring that the inlet water pipe 5 is not emptied. When the water supply from the water plant is sufficient and the water pressure is relatively stable, the outlet water pressure detection device 13 on the outlet water pipe 6 provides real-time feedback signals based on changes in the actual water consumption and water pressure demand of downstream users. The control system automatically adjusts the speed of each variable frequency motor accordingly—when user water consumption increases and outlet water pressure decreases, the speed of the booster pump 4 is increased to increase the water supply flow and pressure; when user water consumption decreases and outlet water pressure increases during nighttime or other periods, the speed of the booster pump 4 is reduced to reduce energy consumption and pipe pressure, achieving constant pressure or on-demand pressure regulation water supply. The above control logic is a mature existing technology. Those skilled in the art can adjust the specific parameter thresholds according to the actual working conditions. There is no need to make creative improvements to the control program itself. The corresponding functions can be achieved simply by adapting the existing control logic to the overall structure of this water supply vehicle.

[0038] The beneficial effect of this setup is that, through dynamic detection and frequency conversion adjustment at both the inlet and outlet, the water supply system can automatically adapt to changes in the external water source 7 conditions and fluctuations in user water demand. This avoids supply interruptions or cavitation caused by insufficient pressure from the external water source 7, and solves problems such as unstable water supply pressure and insufficient water pressure for high-rise users caused by differences in the amount of water used by users at different times. At the same time, it achieves the goals of energy saving, consumption reduction, and extending the service life of the booster pump 4.

[0039] As a preferred embodiment, a flow stabilizer 14 is also provided on the water inlet pipe 5. The flow stabilizer 14 is a closed container with a certain volume. Its function is to absorb and buffer the pressure fluctuations in the external water source 7 pipeline, and provide relatively stable water inlet conditions for the booster pump 4. Especially when the external water source 7 comes from a long-distance water transmission pipeline or when there are fluctuations in the water supply pressure, the flow stabilizer 14 can effectively prevent the booster pump 4 from being damaged by cavitation due to a sudden drop in water inlet pressure.

[0040] A pressure stabilizing tank 15 is also installed on the water outlet pipe 6. The pressure stabilizing tank 15 is a pressure vessel pre-filled with a certain pressure gas. It is set between the water outlet side of the booster pump 4 and the user's pipe network to buffer the pressure shock generated by the instantaneous change in the water supply system when the user's water consumption changes, and to smooth the pressure fluctuation of the water outlet pipe 6, so that the pressure supplied to the user's pipe network is more stable, reducing the frequent start and stop of the booster pump 4, and further protecting the equipment and pipeline.

[0041] This new energy relay booster water supply vehicle also includes a water intake pump 16, which is powered by AC power output from the voltage inverter system 2, or by power supplied through an external discharge interface on the chassis via another independent power supply branch. The water intake pump 16 is configured as a mobile submersible pump, which is carried to an external water source 7 located far from the parking position during operation, such as a water tank, open water bladder, water tank in other areas, or a distant fire hydrant. It is then connected to the inlet pipe 5 of the water supply equipment group 3 via a water hose. After the water intake pump 16 starts, it injects water from the distant water source into the inlet pipe 5 via the water hose, and then the booster pump 4 performs secondary pressurization before supplying it to the user's pipe network. This configuration allows the vehicle to effectively obtain water even when the external water source 7 is far from the work point, with a maximum water intake distance of over 200 meters, greatly expanding the applicability of emergency water supply.

[0042] As a preferred embodiment, the cargo box 9 is equipped with a rainproof enclosure 17, which encloses the voltage inverter system 2 and the water supply equipment group 3 within its internal space, providing all-weather protection for the electrical equipment and water supply pipelines, enabling the vehicle to operate normally even in severe weather conditions such as rain and snow. The rainproof enclosure 17 is provided with an air inlet window 18 and an exhaust window 19. In one embodiment, the air inlet window 18 and the exhaust window 19 can adopt a manually adjustable louver structure; in another embodiment, an electric fan can be installed at the exhaust window 19 to actively accelerate the circulation and flow of air inside and outside the rainproof enclosure 17, promptly dissipating the heat generated by the operation of the voltage inverter system 2 and the booster pump 4, ensuring reliable operation of the equipment within a suitable temperature range.

[0043] A main control system cabinet 20 is located on the side of the rainproof enclosure 17. The cabinet door of the main control system cabinet 20 has an upward-opening structure, revealing the operation panel when opened. The main control system cabinet 20 integrates the main power switch and the water supply equipment operation panel. The main power switch is connected in series between the output terminal of the voltage inverter system 2 and the input terminal of the water supply equipment group 3, which can realize the overall on / off control of the power supply circuit of the water supply equipment group 3, facilitating the quick disconnection of power supply during work preparation, emergency stop, and maintenance. The water supply equipment operation panel is equipped with start / stop buttons for each booster pump 4, speed display, and display instruments or touch screens for system pressure, flow, and other parameters. Operators can operate from the ground to achieve centralized monitoring of the entire water supply operation process.

[0044] A shelf 21 is fixedly installed on the top of the rainproof enclosure 17, and multiple LED site lights 22 are installed around the shelf 21. The LED lights are powered by the power battery of the new energy chassis 1 or an additional low-voltage battery, providing sufficient illumination for the work area during emergency water supply operations at night. In addition, each equipment compartment inside the rainproof enclosure 17 is also equipped with an internal light, facilitating equipment inspection and operation at night or in poor lighting conditions, ensuring all-weather operation capability. Both the LED site lights 22 and the internal lights can be selected from commercially available industrial lighting products, and their installation and fixing methods are existing conventional methods, which will not be described in detail.

[0045] Furthermore, as an alternative, in specific application scenarios, if the external discharge power of the chassis itself is insufficient to drive the high-power water supply equipment group 3, an on-board generator set or a chassis power take-off unit driving a generator can also be used as the power source for the water supply equipment group 3. However, compared with the direct power extraction scheme of the new energy chassis 1 of the present invention, the above methods have significant disadvantages in terms of noise control, exhaust emissions, and environmental access rights. The present invention preferably adopts the technical route of powering the new energy chassis 1 through the voltage inverter system 2 via external discharge to achieve the best comprehensive beneficial effect.

[0046] Example 2 This embodiment provides a new energy relay booster water supply method, which can be implemented based on the new energy relay booster water supply vehicle described in any of the above embodiments. It can be applied to emergency scenarios in urban communities such as emergency repairs of burst water supply pipes, damage to the main water supply equipment in pump rooms, or insufficient water pressure after a long period of water outage.

[0047] This method no longer follows the traditional water tanker truck "one-way supply from water storage point to water use point", but instead uses the water supply truck itself as a mobile relay booster node in the urban water supply network.

[0048] Specifically, this method includes the following steps: Step 1: Mobile Deployment. Utilizing the advantages of the new energy chassis 1—its compact and flexible size, ability to display new energy green license plates, and exemption from restrictions on fuel vehicles—the water supply truck can be driven directly into and parked at the location closest to the user's water supply network 8 access point, including but not limited to narrow roads within the community, underground parking lots, or areas near pump rooms. This ensures the water supply truck is parked as close as possible to the user's network access point, significantly shortening the length of the outlet pipeline and reducing pressure loss along the way.

[0049] Step Two: Constructing a Relay Water Supply Link. Connect the inlet pipe 5 of water supply equipment group 3 to an external continuous water source via fire hoses or quick-connect hoses. This external continuous water source can be a fire hydrant on the municipal fire pipeline outside the community, the outlet of a large-tonnage water tanker, or a water source drawn from a distant natural water body by a water pump. Simultaneously, connect the outlet pipe 6 of water supply equipment group 3 to the user's water supply network 8. Specific connection methods include, but are not limited to: connecting to the inlet of the water storage tank in the community's pump room, connecting to the front-end pipeline of the secondary water supply equipment, or directly connecting to the building's main water supply pipeline. Thus, this vehicle establishes a complete physical water flow channel between the external continuous water source and the user's water supply network 8.

[0050] Step 3: Power Supply Start-up. Start the voltage inverter system 2, which draws DC power from the power battery through the external discharge interface of the new energy chassis 1 and converts it into AC power to supply the water supply equipment group 3. This step utilizes the chassis's own electrical energy to drive the water supply operation without starting any independent fuel generator set.

[0051] Step 4: Intermediate Boost Water Supply. The booster pump 4 in water supply equipment group 3 operates under AC power, boosting the pressure of the external continuous water source and continuously delivering it to the user's water supply network 8 via the outlet pipeline. During the water supply process, the control system senses the external water supply capacity in real time based on the inlet pressure detection device 11 and inlet flow detection device 12 installed on the inlet pipeline 5, and simultaneously senses the user's water demand in real time based on the outlet pressure detection device 13 installed on the outlet pipeline 5. When the inlet water pressure is low or the flow is insufficient, the speed of the booster pump 4 is automatically reduced to prevent cavitation. When the user's water consumption increases, causing a drop in water pressure, the speed of the booster pump 4 is automatically increased to maintain stable pressure. When the user's water consumption decreases, the speed of the booster pump 4 is automatically reduced to save energy. This achieves automatic pressure adaptation of the network throughout the entire water supply cycle.

[0052] This relay-pressurization water supply method essentially transforms water supply trucks into intelligent booster relay stations connecting external water sources and user pipe networks. Its advantages are as follows: Regarding the water source, since it connects to a continuous external water source rather than a vehicle-mounted limited water tank, uninterrupted water supply can be achieved as long as the external water source remains uninterrupted, completely overcoming the bottleneck of insufficient capacity in traditional water tankers; In terms of power, it uses the chassis' own electric power drive, completely eliminating the need for diesel generator sets, achieving quiet, zero-emission operation, especially suitable for noise-sensitive scenarios such as nighttime repairs, while also being unaffected by restrictions on fuel-powered vehicles; In terms of control, dynamic detection and frequency conversion adjustment at both the inlet and outlet ends enable the water supply process to adapt to changes in external water sources and fluctuations in user water usage, ensuring stable pipe network pressure and solving the problems of insufficient water pressure for high-rise users and uneven water usage at different times. This method significantly shortens the emergency water supply restoration time to within one hour, significantly improving the capacity for ensuring people's livelihoods.
