Description

Technical Field

[0001] This utility model belongs to the field of intelligent water supply technology, specifically relating to an adaptive full-area water supply device based on the coordinated control of centralized boosting and distributed energy storage, which is particularly suitable for water supply scenarios where users are dispersed, water pressure demand spans a wide range, and head is complex. Background Technology

[0002] A zoned pressure-controlled water supply system is a water supply method that divides the water supply area into multiple pressure levels based on differences in user water pressure requirements or changes in terrain elevation. Its core principle is to provide appropriate water pressure to different areas through independent booster equipment or pressure regulating devices, avoiding problems such as overpressure in low-pressure areas or insufficient pressure in high-pressure areas caused by unified water supply.

[0003] For special scenarios with dispersed users, large head spans, and significant differences in water pressure demands (such as mountainous towns and high-rise building clusters), traditional solutions suffer from the following technical bottlenecks: 1. High infrastructure costs: Each pressure zone requires independent configuration of booster equipment (such as a combination of water pumps and pressure reducing valves), leading to complex pipeline laying and a surge in the number of devices; 2. Insufficient control precision: A single sensor (such as a pressure transmitter) cannot achieve multi-parameter coordinated control, easily causing pipeline pressure fluctuations and the risk of pipe bursts; 3. Energy consumption and maintenance issues: Frequent start-ups and shutdowns of booster pump sets increase energy consumption, and the operation and maintenance costs of dispersed equipment are high; 4. Poor adaptability: Traditional zoned pressure systems cannot cope with dynamic changes in terrain (such as water level fluctuations in mountainous areas) and cannot achieve pressure balance across the entire area.

[0004] Although there has been exploration of related technologies in recent years, fundamental limitations have not been overcome. Intelligent control technologies, such as the cloud-based pressure prediction system in Ningshui, Chengdu, can optimize overall energy consumption, but they rely on fixed pipeline models and cannot adapt to the dynamic zoning needs of dispersed user scenarios. Mechanical buffer devices, such as the patented CN2432256Y, balance pressure through pressure tanks, but they are only applicable to a single user end and cannot achieve full-area coordination.

[0005] Therefore, there is an urgent need to design an economical, simple, easy-to-maintain, and adaptable whole-area water supply system that can be used in special scenarios where users are dispersed, the head span is large, and the water pressure demand varies significantly. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of traditional zoned pressure water supply systems and provide an economical, simple, easy-to-maintain, and adaptable whole-zone water supply device suitable for special scenarios with dispersed users, large head spans, and significant differences in water pressure requirements.

[0007] The technical solution adopted by this utility model to solve its technical problem is: an adaptive whole-area water supply equipment, including a water supply main pipe and a water distribution pipe, with multiple zone water pipes connected at intervals on the water distribution pipe, the zone water pipes being connected to the zone user end, a centralized boosting device being provided on the water supply main pipe, and a pressure stabilizing device being provided on the zone water pipes.

[0008] The centralized booster unit mainly consists of a water supply control cabinet, a booster pump set, a check valve, a pressure stabilizing tank, and a water supply pressure sensor. The booster pump set, check valve, pressure stabilizing tank, and water supply pressure sensor are sequentially installed on the main water supply pipe. The booster pump set and water supply pressure sensor are electrically connected to the water supply control cabinet, which controls the start and stop of the booster pump set.

[0009] The pressure stabilizing device mainly consists of a pressure stabilizing control cabinet, an inlet valve, a water storage tank, and an outlet valve. The inlet valve, water storage tank, and outlet valve are sequentially installed on the zoned water pipes. The water storage tank is equipped with a tank level sensor, a one-way air inlet valve, and a tank pressure sensor. The inlet valve, outlet valve, tank level sensor, and tank pressure sensor are electrically connected to the pressure stabilizing control cabinet, which controls the opening and closing of the inlet valve and outlet valve.

[0010] The pressure stabilizing control cabinet is connected to the water supply control cabinet via communication.

[0011] Optionally, a pressure-replenishing device is provided at intervals on the water distribution pipe. The pressure-replenishing device mainly consists of a pressure-replenishing control cabinet, a pressure-replenishing pump, a pressure-replenishing check valve, a pressure-replenishing stabilizing tank, and a pressure-replenishing sensor. The pressure-replenishing pump, pressure-replenishing check valve, pressure-replenishing stabilizing tank, and pressure-replenishing sensor are sequentially arranged on the water distribution pipe. The pressure-replenishing pump and pressure-replenishing sensor are electrically connected to the pressure-replenishing control cabinet. The pressure-replenishing control cabinet controls the start and stop of the pressure-replenishing pump. The pressure-replenishing control cabinet is communicatively connected to the water supply control cabinet.

[0012] The utility model is used as follows: The water supply area is divided into multiple zones according to the actual situation. The main water supply pipe with a centralized booster device is connected to the municipal water network, and the distribution pipe is connected to the main water supply pipe. The distribution pipe connects the various horizontal or vertical zones in the water supply area. The zone water pipe of each zone is connected to the distribution pipe. Tap water is supplied to the users of the entire zone through the zone water pipe and the pressure stabilizing device. In the future, the distribution pipe can be extended to add more zones as needed, or the distribution pipe can be shortened to reduce the number of zones. However, it is necessary to pay attention to controlling the booster value of the main water supply pipe. In addition, the pressure of each zone can be set through the pressure stabilizing control cabinet of each zone, or the working pressure of each pressure stabilizing device can be set according to the water supply control cabinet in the centralized booster device.

[0013] The principle of this utility model is as follows: When the pressure detected by the pressure sensor of any zone tank is less than the pressure detected by the water supply pressure sensor, the water supply control cabinet controls the booster pump group to start and boost the pressure until the pressure detected by the water supply pressure sensor is greater than the preset upper limit pressure of any zone tank. Then, the water supply control cabinet controls the booster pump group to stop, the check valve prevents liquid backflow, and the pressure stabilizing tank stabilizes the water supply pressure and prevents frequent start-ups of the equipment when the flow rate is low or there is leakage. The above method is used to prepare pressure for each zone.

[0014] When the pressure sensor of the tank in the zone detects that the pressure is lower than the preset lower pressure limit, the pressure stabilizing control cabinet controls the inlet and outlet valves to open, and the pressurized tap water enters the water storage tank. As the water volume in the tank increases, the air in the tank is compressed and the pressure is stored. When the pressure sensor of the tank detects that the pressure reaches the preset upper pressure limit, the inlet valve closes, and the water storage tank stores tap water at a suitable pressure to supply users in the zone. When the pressure sensor of the tank in the zone detects that the pressure is lower than the preset lower pressure limit, the inlet valve opens again to replenish water and pressure.

[0015] As the air in the water storage tank is repeatedly compressed, some air mixes with the water and is discharged along with it, resulting in a reduction in the amount of air inside the tank. This causes a decrease in the regulating capacity of the water storage tank, which manifests as an abnormal rise in the liquid level. When the tank level sensor detects that the liquid level inside the tank has reached the preset upper limit, the pressure stabilizing control cabinet controls the inlet valve to close and the outlet valve to open, allowing the water inside the tank to be continuously discharged and the liquid level inside the tank to drop. When the external air pressure is greater than the internal air pressure, air enters the water storage tank through the one-way air inlet valve. When the tank level sensor detects that the liquid level inside the tank has reached the preset lower limit, the pressure stabilizing control cabinet controls the inlet valve to open and replenish water and pressure normally, thereby achieving air replenishment inside the tank. During the air replenishment process, there may be a slight pressure deficiency, but since the tank is installed above the water point, it will not affect the water supply to users in the zone.

[0016] In summary, this utility model adopts a topology architecture of centralized pressurization and zoned energy storage. A single pressurization device covers the entire water supply area, while distributed energy storage tanks enable adaptive pressure regulation, overcoming the limitations of traditional zoned pressurization requiring independent equipment. It designs a dual-parameter coupled control system of "pressure-level," based on real-time feedback from the water storage tank's level and pressure sensors, achieving dynamic switching between "air replenishment" and "water replenishment" modes. Compared to single-parameter control schemes, this improves pressure fluctuation suppression efficiency. Furthermore, it constructs an intelligent linkage control system, using a wireless / wired hybrid communication architecture between the water supply control cabinet and the pressure stabilization control cabinet to support free serial and parallel zoned modes in complex terrains, filling the technological gap in traditional fixed pipeline network topology systems.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: By integrating an Internet of Things sensor network, dual-parameter dynamic adjustment and multi-level pressure feedback control architecture, the present invention can effectively solve the technical problems of equipment redundancy, high energy consumption and large pressure fluctuation in traditional zoned pressure water supply systems.
