[0002] In some high-altitude and cold regions, the ambient temperature is low, often below zero degrees Celsius. Farmers and herders mostly rely on wells or riverbeds for their water. When the temperature is below zero for extended periods, the water surface is prone to freezing, making it impossible to draw water normally.

[0014] The beneficial effects that this application can achieve are: This application proposes a water supply system for high-altitude and cold regions. The system utilizes photovoltaic power generation and energy storage devices to form an independent power supply system, eliminating reliance on the traditional power grid. In high-altitude and cold regions where power grid coverage is typically weak, the adoption of a localized, distributed photovoltaic energy storage solution effectively solves the energy supply problem, enabling the water supply system to operate independently and stably in remote and harsh environments. One of the challenges in high-altitude and cold regions is the potential for water to freeze in low-temperature environments, affecting normal water supply. An insulation subsystem can heat and insulate vulnerable areas such as water intake, purification, pressurization, and water use, effectively preventing pipes and equipment from freezing or cracking at extreme temperatures. Furthermore, the water supply system can automatically activate emergency plans during energy shortages, prioritizing the operation of the most critical equipment, thereby achieving precise delivery of limited energy resources.

[0022] Example 1 Reference Figures 1-12 The first embodiment of this application provides a water supply system for high-altitude and cold regions, including a power supply subsystem, a water supply subsystem, and a thermal insulation subsystem; the power supply subsystem includes a photovoltaic power generation device 30 and an energy storage device 90, and the water supply subsystem includes at least one of the following connected via a pipeline network: a water intake device 40, an antifreeze water purification station 10, a booster pump station 20, and a water consumption device 80; wherein: The insulation subsystem is configured to optionally heat and / or insulate at least one of the water intake device 40, the antifreeze purification water station 10, the booster pump station 20, and the water use device 80; The power supply system is configured to optionally power the water supply subsystem and / or the insulation subsystem via photovoltaic power generation device 30 and / or energy storage device 90.

[0023] In this embodiment, the water intake device 40 is located at the water source, which can be well water or river water. The water from the water source is transported by the water intake device 40 to the antifreeze water purification station 10 for purification. The purified water can be used directly at the antifreeze water purification station 10 via the water-using device 80, or it can be pressurized by the booster pump station 20 to be transported to more distant locations, such as residential villages. The antifreeze water purification station 10 and the booster pump station 20 can be integrated into a single insulated room 70, or they can be used in other ways. Figure 1 The components shown are placed within an insulated chamber 70 for use. The insulation subsystem heats a relatively sealed insulated chamber, allowing at least one of the water intake device 40, the antifreeze purified water station 10, the booster pump station 20, and the water use device 80 to be located within the insulated chamber, thereby achieving heating and / or insulation of at least one of these components. It should be noted that heating or insulating the water intake device 40 refers to heating or insulating a portion of the pipes within the water intake device 40.

[0024] The insulation subsystem is used for heat exchange with the ambient air inside the insulation chamber 70, maintaining the ambient temperature within the chamber within a preset range. Multiple high-precision temperature sensors can be installed at different locations within the insulation chamber 70, such as one each at the top, middle, and bottom. This allows for comprehensive monitoring of the temperature distribution within the insulation chamber 70, preventing localized temperature anomalies from affecting overall temperature control. For example, the top sensor monitors the temperature of areas where hot air accumulates, while the bottom sensor reflects potential low-temperature areas near the ground. The temperature sensors transmit the monitored temperature data to the central control system in real time. The control system analyzes and judges the data based on a preset temperature range, such as 5℃-15℃, which can be adjusted according to actual needs. When any temperature sensor detects that the temperature of the insulation chamber 70 is below the lower limit of the preset range, such as 5℃, the control system immediately issues a command to activate the insulation subsystem. When the temperature of the insulation chamber 70 reaches the upper limit of the preset range, such as 15℃, the control system controls the insulation subsystem to reduce power operation or suspend operation to avoid overheating and energy waste. Simultaneously, temperature monitoring continues in real time, and if the temperature shows a downward trend, the corresponding equipment is restarted.

[0025] Example 2 Based on Embodiment 1, this embodiment provides a control system configured to estimate the target power supply of the power supply system in a target time period based on historical data of the power supply system in a preset time period. When the target power supply is less than a preset threshold, the system obtains the priority ranking of each electrical device and the insulation subsystem in the water supply subsystem, and the power supply system supplies power based on the priority ranking.

[0026] The step of estimating the target power supply of the power supply system during the target time period includes: Acquire historical data for a preset time period, wherein the historical data includes at least one of photovoltaic power generation data, energy storage device data, and electricity consumption data of the water supply system; Obtain weather forecast data for the target time period, and use a trained machine learning model to predict the target power generation of the photovoltaic power generation device within the target time period based on photovoltaic power generation data and weather forecast data. Obtain the remaining power of the energy storage device at the beginning of the target time period, and based on the target power generation and historical power consumption patterns, estimate the charging and discharging amount of the energy storage device during the target time period to obtain the available power of the energy storage device during the target time period. The target power supply is obtained based on the target power generation and available power. A flowchart illustrating the process of obtaining the target power supply is shown below. Figure 13 As shown.

[0027] The control system is used to regulate the power distribution between the photovoltaic power generation device 30 and the energy storage device 90. Especially when the photovoltaic power generation device 30 generates insufficient power, according to a preset priority ranking, higher-priority devices have higher power consumption rights, ensuring that limited resources are used more effectively. It should be noted that the control system is an embedded system integrating hardware and software; its core functions are data acquisition, intelligent decision-making, and command execution. The control system has multiple communication connections with sensors. Examples of sensor types include: an irradiance sensor to measure solar radiation intensity to assess power generation efficiency; a photovoltaic panel temperature sensor to monitor panel temperature, as panel temperature affects power generation efficiency; a current / voltage sensor to monitor the output power and power generation of the photovoltaic array in real time; a battery management system to provide key parameters such as remaining power, voltage, current, temperature, and health status; a flow sensor installed at the water intake, the outlet of the booster pump station 20, and key water usage points to monitor the actual water supply; and a pressure sensor installed in the pipeline network to monitor water pressure and determine if there is a leak or blockage. Sensors include: level sensors installed in raw water tanks and clear water tanks to monitor water levels and control the start and stop of water intake pump 41 and water supply pump; smart water meters installed on the outlet pipe of booster pump stations to monitor water volume; water quality sensors installed in the antifreeze purification water station 10 to monitor turbidity, residual chlorine, etc.; ambient temperature sensors used to monitor atmospheric temperature; equipment surface temperature sensors attached to key equipment such as water intake device 40, purification water station tank, and booster pump 65; pipeline surface temperature sensors mainly installed on exposed and easily frozen pipe sections; and pipeline heating cable status sensors that monitor the current of the heating cable to determine whether it is working properly.

[0028] The power supply logic of the control system is explained as follows: The control system will preset a device priority list, for example, dividing each electrical device into four priority levels: highest priority, high priority, medium priority and low priority.

[0029] The highest priority includes: core pipeline antifreeze and insulation, water intake device 40 and core equipment of the water purification station antifreeze and power supply of the control system itself. The highest priority equipment is the electrical equipment that needs to be powered first.

[0030] High priority includes: water intake device 40 and antifreeze purification water station 10; high priority equipment can start minimum water supply production while ensuring that the system does not freeze, so as to guarantee the user's basic water needs.

[0031] Medium priority includes: insulation of common areas of booster pump station 20 and water supply unit 80, so that such equipment can be activated to improve service quality when there is a surplus of energy.

[0032] Low priority includes: insulation of non-core areas, such as individual branch ends; high-power, non-emergency cleaning and disinfection equipment; and low-priority equipment that can be reduced or delayed in operation during energy shortages.

[0033] It should be noted that the priority is not always fixed; the control system will make fine adjustments based on real-time conditions, for example: If the temperature sensor reading of a low-priority pipe suddenly drops to near the freezing point, the control system can temporarily increase its insulation priority to prevent that point from freezing.

[0034] At night, the priority of heat preservation is generally increased; before the peak water usage during the day, the priority of booster pump station 20 can be temporarily increased.

[0035] If the sensor detects a pipe rupture, such as a sudden pressure drop, the control system will immediately cut off the water supply to the area and adjust the priority of related equipment. The detected pipe rupture will also notify relevant maintenance personnel via SMS, email, and push notifications. 3 Specifically, photovoltaic (PV) power generation data is obtained from PV inverters and smart meters, including historical power generation curves, such as points every 15 minutes or 1 hour, total daily power generation, peak power generation, and the time of occurrence. Energy storage device data is obtained from battery management systems, including historical daily charge / discharge amounts, charge / discharge power, cycle count, and health status. Water supply system electricity consumption data is obtained from smart meters or control systems of various electrical devices, such as water pumps, purification equipment, and heating cables, including historical total load curves, power consumption of individual devices, and peak load times. The system extracts the above data for a preset time period, such as the past 30 days, from its internal database or cloud platform. Data cleaning is performed to remove outliers caused by communication interruptions, such as negative or extremely high power generation, and data alignment is then performed to form a standard time-series dataset.

[0036] In the step of predicting the target photovoltaic power generation for a target time period, the photovoltaic power generation sequence and seasonal index of the same period over the past N days are used as historical features. Weather forecast data for the target time period obtained from the meteorological service API, including hourly or 3-hourly solar irradiance / radiance, cloud cover, temperature, precipitation probability, and air quality, are used as prediction features. A gradient boosting decision tree model can be used, with the processed historical data and weather forecast data input into the pre-trained model. The model learns the mapping relationship between historical power generation patterns and future weather conditions, and finally outputs the predicted power generation curve for the target time period in hourly units. After integration, the target power generation can be obtained.

[0037] In the step of estimating the available power of an energy storage device within a target time period, the remaining power of the energy storage device at the start of the target time period is first obtained. The charging and discharging phases are then simulated. For example, during daytime photovoltaic power generation, the simulation uses the portion of the predicted power generation exceeding the current load demand to charge the energy storage device. The charging amount is limited by the maximum charging power and the total battery capacity. At night or during periods of no light, the simulation simulates the energy storage device supplying power to the system. The discharging amount is limited by the maximum discharging power and a minimum remaining power level set to prevent over-discharge, such as 20%. The available power is the total amount of electricity that the energy storage device can release during the target time period, as calculated by the simulation.

[0038] The target power supply is obtained by adding the target power generation and the available power. The target power supply represents the total net energy that the power supply system can provide to the entire water supply system during the entire target time period.

[0039] Optionally, the control system is further configured to: The first basic energy consumption of each electrical device in the water supply subsystem is obtained. Based on the weather forecast data for the target time period, the second basic energy consumption of the insulation subsystem is obtained within the target time period. Based on the first basic energy consumption and the second basic energy consumption, the total basic energy consumption of the water supply system in the target time period is obtained. Based on the actual and predicted electricity consumption over a preset time period, a deviation confidence level is obtained. Then, based on the base total energy consumption and the deviation confidence level, a preset threshold is obtained. A flowchart illustrating the process of obtaining the preset threshold is shown below. Figure 14 As shown.

[0040] Specifically, the first basic energy consumption refers to the energy that all electrical equipment must consume to meet the most basic water supply function within the target time period. This is not the rated power consumption, but the lower limit of energy consumption. For example, for water intake devices, the energy consumption for the shortest daily operating time is calculated based on the minimum daily water demand; for antifreeze water purification stations, the energy consumption required for their core treatment units, such as backwash pumps and dosing equipment, to operate at the minimum treatment load; and for booster pump stations, the intermittent operating energy consumption required to maintain the minimum service pressure of the pipeline network, rather than the peak pressure. The specific calculation method can be based on the equipment nameplate power and the minimum operating strategy set in the control system.

[0041] The second base energy consumption refers to the minimum insulation energy required to prevent all pipes and equipment from freezing under the predicted ambient temperature for the target time period. The system internally stores a temperature-heat dissipation rate model. This model can calculate the minimum heating power required to keep pipes and equipment above freezing based on the predicted ambient temperature. The second base energy consumption is based on weather forecasts for the target time period; for example, if extreme cold is predicted for tomorrow, the second base energy consumption may increase sharply; if mild weather is predicted, the second base energy consumption will decrease.

[0042] Bias confidence level is an indicator that quantifies the uncertainty of forecasting. In obtaining the bias confidence level, the system retrieves data for a preset time period, such as the past 30 days, and compares the predicted electricity consumption with the actual electricity consumption for each day. Mean absolute percentage error or standard deviation can be used. For example, if the average error in the past is 5%, then the bias confidence level is 1.05. If past forecasts have been very inaccurate, with an average error of 15%, then the bias confidence level is 1.15.

[0043] The preset threshold is equal to the product of the base total energy consumption and the deviation confidence level. By using the deviation execution level, a safety buffer is added. That is, the more inaccurate the historical predictions are, the higher the value of this safety buffer, and the more conservative the system decision is, so as to ensure the normal operation of the system.

[0044] To make it easier to understand, the following example is provided: The scene is set as follows: Geographical location: High-altitude, cold region, winter.

[0045] Target time period: the next 24 hours, from 18:00 today to 18:00 the next day.

[0046] Weather forecast: The weather forecast indicates that the next 24 hours will be characterized by continuous overcast and snowy weather with no sunshine and an average temperature of -25℃.

[0047] System status: The energy storage device has 40% remaining power at the current time, i.e., 18:00 today, which is equivalent to 40kWh. Assuming the total capacity is 100kWh.

[0048] Predicted photovoltaic power generation target: Due to the forecast of continuous cloudy and snowy weather, the predicted power generation is approximately 0 kWh.

[0049] Estimated available energy capacity of the energy storage device: Initial capacity: 40kWh. With no charging source for the next 24 hours (i.e., zero photovoltaic power generation), the system needs to be fully discharged to maintain operation. To prevent battery over-discharge damage, a minimum depth of discharge of 20% is set, meaning 20kWh of energy must be retained. The available capacity is calculated by subtracting the minimum retained capacity from the initial capacity; the available capacity is 20kWh, representing the total energy that the energy storage device can safely release.

[0050] First basic energy consumption: To meet the most basic water supply, the water intake, purification, and pressurization equipment requires a minimum daily operating energy consumption of 5 kWh.

[0051] Second, basic energy consumption: Due to the forecast average temperature dropping to -25℃, thermodynamic model calculations indicate that the heat tracing systems for all critical pipelines and equipment, such as water intakes, main water pipes, water stations, and pumping stations, will need to operate continuously or intermittently at high frequencies to prevent freezing. The minimum energy consumption of the insulation subsystem is estimated at 18 kWh. The total basic energy consumption is 23 kWh of electricity.

[0052] Obtaining the bias confidence level: Analysis of data from the past 30 days revealed that due to the variable weather in mountainous areas, there is an average error of about 10% in electricity consumption prediction. Therefore, the bias confidence level is 1.10; the preset threshold is calculated by multiplying the base total energy consumption by the bias confidence level, and the preset threshold is 25.3 kWh.

[0053] If the target power supply (20kWh) is less than the preset threshold (25.3kWh), the water supply system immediately enters emergency power supply mode.

[0054] The control system precisely allocates the 20kWh of energy according to preset priorities: Highest priority: 12 kWh will be consumed for core pipeline freeze protection and insulation. Insulation power will be reduced for some non-core pipeline sections, and centralized power will be used to ensure the main pipeline network remains unfrozen. 4 kWh will be consumed for freeze protection of core equipment in the water intake and purification stations. 1 kWh will be consumed for the control system's own power supply. Subtotal: 17 kWh.

[0055] High priority: Remaining energy is 20kWh - 17kWh = 3kWh. This 3kWh is insufficient to simultaneously meet the minimum operating energy consumption (5kWh) for water intake and purification. The following decision will be made: The control system will activate the water intake device for a short period at night when power is relatively abundant, consuming 3kWh to draw a minimum amount of water from the water source and store it in the pool. The purification process will not run for the time being. Subtotal: 3kWh.

[0056] Medium and low priority: Booster pump stations will be forcibly shut down. Water pressure at the user end will drop to zero or extremely low, making normal water use impossible, but the core of the pipeline network will not freeze or crack due to intact insulation. Insulation in non-core areas: Forcibly shut down or reduced to extremely low power. All non-emergency electrical equipment: Power will be cut off.

[0057] This allows the system to maintain the integrity and survivability of its core architecture even in the event of unavoidable energy shortages, through accurate forecasting and decisive priority management, at the expense of secondary functions, thus providing conditions for rapid recovery once the weather improves.

[0058] Example 3 like Figures 5-9 Based on Embodiment 1, this embodiment provides a specific structure for a water intake device 40. The water intake device 40 includes a float and a water pump 41. The float has a buoyancy cavity 44 to allow it to float on the water surface. The float has a through hole 48, and a heating element 45 is installed inside the buoyancy cavity 44 to heat the float so that the temperature of the well water in the through hole 48 is higher than a preset temperature. The water pump 41 is installed inside the through hole 48 of the float and connected to the float. The water pump 41 is submerged in the incoming water and is connected to the inlet of the water treatment component 50 through a pumping pipe 47. It should be noted that when the water source is a traditional electromechanical well, the water intake device 40 only includes the water pump 41. The float can be added or removed according to actual usage requirements; that is, only the water pump 41 can be installed in the electromechanical well without the float.

[0059] Specifically, the first direction is vertical. The through hole 48 is configured to pass through the floating component. When the floating component is placed in the well, part of the floating component is below the water surface, and part of the floating component is above the water surface. The through hole 48 communicates with the well environment, and part of the well water is located within the through hole 48. By setting a buoyancy cavity 44 in the floating component, the entire floating component can float in the well water. The water pump 41 is connected to the floating component. While the water pump 41 pumps water, it also acts as a counterweight. The water pump 41 applies a downward gravitational force to the floating component, lowering its center of gravity and improving its stability when floating in the well water. This prevents the floating component from changing from a vertical to a horizontal state, which would affect the water pump 41's pumping or the heating effect of the heating element 45. The water pump 41 can be a submersible water pump 41. The pumping pipe 47 is connected to the outlet of the water pump 41. The pumping pipe 47 is also connected to an outlet hose. The outlet of the outlet hose can be connected to a water storage tank. When the float moves up and down with the well water level, the outlet hose can bend or straighten to compensate for the height of the float and ensure that the water pump 41 can move up and down synchronously with the float.

[0060] A heating element 45 is provided inside the buoyancy chamber 44. The heating element 45 can heat the float, which can transfer heat to the well water, thus heating the well water in the through hole 48 and maintaining the temperature of the well water in the through hole 48 above a preset temperature. For example, the preset temperature can be 3-9°C. This prevents the well water in the through hole 48 from freezing or melts the ice layer inside the through hole 48, ensuring that the portion of the pumping pipe 47 located inside the through hole 48 is not frozen or can be thawed, thus guaranteeing normal water pumping. The float can move with the rise and fall of the well water level. That is, when the well water level rises or falls, the float can still heat the ice layer to melt it or maintain the water surface from freezing. The pumping pipe 47 can also be connected to the outlet hose to ensure that when the float moves up and down with the well water level, the height can be compensated through the outlet hose. This ensures that the pumping pipe 47 can also move up and down with the float, and that the fixed length of the pumping pipe 47 will not interfere with the movement of the float due to the rise and fall of the water level.

[0061] It should be noted that when the float is heated, the purpose is not to heat all the well water, but only to heat the portion near the water surface and mainly the part inside the through hole 48, in order to maintain the temperature of the well water inside the through hole 48 above the preset temperature. For example, the float can be heated when pumping is required, or preheated for a period of time before pumping to melt the ice layer on the water surface, or maintained during continuous pumping to prevent the water surface from freezing and ensure normal pumping.

[0062] Optionally, the floating component includes a first buoyancy shell 42 and a second buoyancy shell 43. The first buoyancy shell 42 is circumferentially sleeved around the second buoyancy shell 43. The through hole 48 is configured as a spatial structure enclosed by the second buoyancy shell 43. The through hole 48 extends along a first direction. The first buoyancy shell 42 and the second buoyancy shell 43 are connected at both ends along the first direction by a first retaining ring 421 and a second retaining ring 422. The buoyancy cavity 44 is configured as a cavity structure enclosed by the first buoyancy shell 42, the second buoyancy shell 43, the first retaining ring 421, and the second retaining ring 422.

[0063] It should be noted that this embodiment is only for the convenience of describing the various parts, thereby defining the first buoyancy shell 42, the second buoyancy shell 43, the first retaining ring 421, and the second retaining ring 422 of the floating component. In reality, the first buoyancy shell 42, the second buoyancy shell 43, the first retaining ring 421, and the second retaining ring 422 are independent of each other and are connected by welding, riveting, etc. Similarly, the first buoyancy shell 42, the second buoyancy shell 43, and the second retaining ring 422 can also be integrally formed. The first buoyancy shell 42 and the second buoyancy shell 43 have an annular structure, and the interface shape of the first buoyancy shell 42 and the second buoyancy shell 43 can be circular or polygonal, such as quadrilaterals, hexagons, and octagons. In this embodiment, both the first buoyancy shell 42 and the second buoyancy shell 43 are cylindrical. The outer diameter of the first buoyancy shell 42 is larger than the outer diameter of the second buoyancy shell 43. The first buoyancy shell 42 is located around the second buoyancy shell 43. The first buoyancy shell 42, the second buoyancy shell 43, the first retaining ring 421, and the second retaining ring 422 together form a relatively closed buoyancy cavity 44. It should be noted that multiple lugs can be provided on the first retaining ring 421. Then, by setting lifting ropes or other methods on the lugs, the float can be placed into the well or removed from the well.

[0064] Optionally, the heating element 45 is configured to extend spirally in the buoyancy cavity 44, and the portion of the first buoyancy shell 42 and / or the second buoyancy shell 43 located in the buoyancy cavity 44 is provided with a plurality of limiting buckles 46 for fixing the heating element 45.

[0065] Specifically, by spirally arranging the heating element 45 within the buoyancy cavity 44, the heating element 45 heats the buoyancy cavity 44 more evenly, reducing the occurrence of localized overheating. The limiting buckle 46 can be a U-shaped fastener, which can be fixed by welding, bonding, or bolting. The limiting buckle 46 can be installed only on the first buoyancy shell 42, only on the second buoyancy shell 43, or on both. By setting the limiting buckle 46, the heating element 45 can be further fixed, preventing it from shaking freely.

[0066] Optionally, the first baffle ring 421 is located above the water surface, and at least one end of the heating element 45 passes through the first baffle ring 421 and is connected to the heat source.

[0067] Specifically, the heating element 45 consists of a heating body and a protective sleeve. The heating body is a heating wire, and the protective sleeve passes through a retaining ring. The heating wire can be easily pulled out of the protective sleeve for convenient replacement. The heating body can be configured as a heating wire, in which case the upper end of the heating element 45 passes through the first retaining ring 421. One end of the heating element 45 passing through the first retaining ring 421 can be connected to a power supply. It should be noted that the cable usually needs to be waterproof. As another heating method, the heating element 45 can be a coil, with both ends of the coil passing through the first retaining ring 421. One end of the coil is the steam inlet, and the other end is the steam outlet. The steam inlet is connected to a steam generator, which is located on the ground. When it is necessary to heat the floating component through the heating element 45, steam is supplied to the coil through the steam generator. The heating element 45 and the floating component exchange heat with the well water, thereby achieving the effect of heating the well water. That is, the heat source can be the municipal power grid, a battery, or a steam generator.

[0068] Optionally, the portion of the second buoyancy shell 43 located within the through hole 48 is provided with multiple reinforcing ribs arranged circumferentially, and the two ends of all the reinforcing ribs are respectively connected to the first retaining ring 421 and the second retaining ring 422.

[0069] Specifically, by setting multiple reinforcing ribs, all the reinforcing ribs are arranged in a ring to improve the overall structural strength of the first buoyancy shell 42, the second buoyancy shell 43, the first retaining ring 421 and the second retaining ring 422.

[0070] Optionally, the second retaining ring 422 is submerged in water, and the water pump 41 is installed in the through hole 48 and connected to the second retaining ring 422.

[0071] Specifically, the water intake pump 41 can be directly or indirectly connected to the second retaining ring 422, which can provide support for the water intake pump 41.

[0072] Optionally, the inner wall of the second retaining ring 422 is provided with a protective cover 49, which encloses a protective space. The water pump 41 is located in the protective space, and the protective cover 49 has a clearance hole for the water pumping pipe 47 to pass through.

[0073] Specifically, the protective cover 49 protects the water pump 41, preventing leaves, branches, or other debris from entering the water inlet and causing adverse effects. A handle can be installed at the top of the protective cover 49 to allow external force to be applied.

[0074] Optionally, the protective cover 49 has a plurality of flow holes on its two end sidewalls at least along the first direction. The protective cover 49 is configured to be at least partially disposed within the through hole 48.

[0075] Specifically, flow holes are provided at both ends of the upper part of the protective cover 49 to ensure that well water can move through the flow holes during the lifting and lowering of the floating component, reducing the resistance received by the protective cover 49 during the lifting and lowering of the floating component, thereby improving the stability of the floating component during the lifting and lowering process. In this embodiment, several flow holes are also provided on the side wall of the protective cover 49. The protective cover 49 can be installed on the second retaining ring 422 by welding or bolting. The second retaining ring 422 has a portion protruding into the through hole 48, and the protective cover 49 is configured to be installed on this protruding portion. The protective cover 49 is cylindrical in shape. The protective cover 49 can be completely installed inside the through hole 48, or it can partially protrude outside the through hole 48.

[0076] Example 4 like Figure 3 , Figure 4 As shown, based on Embodiment 1, this embodiment provides a specific structure for an insulated room 70, in which an antifreeze water purification station 10 and / or a booster pump station 20 are configured. The insulated room 70 includes: The first frame encloses and forms a accommodating space; The second frame is set within the accommodating space; The first frame has a first profile surface, and the second frame has a second profile surface close to the first profile surface. An insulation space is formed between the first profile surface and the second profile surface, and the insulation space is used to accommodate insulation material.

[0077] In this embodiment, a first frame and a second frame are provided. The first frame encloses a receiving space, and the second frame is disposed within the receiving space. The first and second frames cooperate to form an insulation space, and an insulation component is disposed within the insulation space. The insulation component encloses a relatively sealed insulation cavity. The first and second frames provide support for the insulation component. The first frame is located outside the insulation cavity, and the second frame is located inside the insulation cavity. Neither the first nor the second frame penetrates the insulation component. The first and second frames are connected by a non-metallic connection that does not penetrate the insulation component. Compared to a metal connection, this reduces the amount of heat transferred from the insulation cavity to the outside, thus improving the insulation effect.

[0078] The enclosed space formed by the first frame may include a bottom surface, a top surface, and multiple side surfaces, such as four, six, or eight. The number of side surfaces formed by the second frame is adapted to the number of side surfaces of the first frame. When the first and second frames enclose an insulated space, the insulated space is used to install insulation material. The insulation material also includes a bottom plate, a top plate, and multiple side plates, such as four, six, or eight. All side plates are connected sequentially along the circumference, and all side plates cooperate with the bottom plate and top plate to form a relatively sealed insulation cavity. In this application, four side plates are used as an example, that is, two opposite side plates are considered as a group, and there are two groups of side plates, with the two opposite side plates being parallel to each other. The insulation material can be made of one or more of rock wool board, polyurethane foam board, polyurethane sandwich, and extruded polystyrene board. A movable door structure can be provided on one of the side walls to facilitate access to and from the insulation cavity.

[0079] Optionally, a photovoltaic power generation device 30 is installed on the outer wall of the insulated room 70. This photovoltaic power generation device 30, such as a monocrystalline / polycrystalline silicon solar panel, converts solar energy into direct current (DC). This DC is then used to charge the battery via an MPPT controller, and an inverter converts the DC stored in the battery into alternating current (AC) to power the electrical equipment. The photovoltaic power generation device 30 is equipped with an intelligent power supply switching system. When there is sufficient sunlight, the electricity generated by the photovoltaic power generation device 30 is prioritized to power equipment such as thermal storage or heating devices. If there is surplus electricity after meeting the immediate power needs of the aforementioned equipment, the surplus is stored in a matching energy storage device 90, which serves as a battery, for later use. When there is insufficient sunlight, such as on cloudy days or at night, or when the power demand of the equipment exceeds the current generating capacity of the photovoltaic power generation device 30, the intelligent power supply switching system quickly switches to battery power mode to ensure the normal operation of the water supply system in high-altitude and cold regions.

[0080] The photovoltaic power generation device 30 operates based on the photoelectric effect of semiconductor materials. When sunlight shines on the surface of the photovoltaic module, photons are absorbed by the semiconductor material and excite electrons to jump to higher energy levels, forming free electrons and holes. These free electrons and holes move and separate within the semiconductor, forming an electric current. In the structure of the photovoltaic module, P-type and N-type semiconductors form a PN junction. When electrons and holes move to this interface, charge separation occurs, generating a voltage. When an external circuit is connected to the photovoltaic module, electrons flow through the circuit, forming an output current.

[0081] The photovoltaic power generation device 30 is equipped with an MPPT controller and an inverter. The MPPT controller is used to regulate the output voltage / current of the photovoltaic power generation device 30 to match the battery pack or load demand and prevent overcharging / over-discharging. The inverter is used to convert the photovoltaic DC power into AC power to power AC loads such as thermal storage or heating equipment. The inverter is preferably a hybrid inverter that integrates the photovoltaic controller, inverter and mains power switching functions, and supports the charging and discharging management of energy storage batteries.

[0082] Optionally, the water supply device 80 includes a water pipe connected to the outlet of the antifreeze purified water station 10 and / or the booster pump station 20, and the outlet of the water pipe is equipped with a valve. It should be noted that the valve is located inside the insulation room 70.

[0083] Optionally, the insulation subsystem includes a heating and / or heat storage device 50, which is used to raise the ambient air temperature. It should be noted that the ambient air here refers to the air within the containment space. The heat storage or heating device includes a housing containing a heat storage medium, and an electric heating element 45 for heating the heat storage medium. Specifically, the electric heating element 45 heats the heat storage medium within the housing, raising the overall temperature of the housing. The housing is made of a thermally conductive material, and the housing raises the air temperature within the insulation chamber 70. The heat storage medium can be thermally conductive oil, water, or heat storage bricks. Similarly, the heat storage or heating device can also be an electric heater, a fan heater, etc.

[0084] Example 5 Based on Embodiment 1, this embodiment provides a specific structure of a pipeline network, which includes at least one of exposed pipelines, antifreeze pipelines, and deeply buried pipelines. The exposed pipelines are installed on the ground, the antifreeze pipelines are configured to be 0.7 meters to 1.5 meters above the ground, and the deeply buried pipelines are configured to be located below the frost layer.

[0085] Specifically, pipeline networks can utilize a combination of exposed pipelines, frost-resistant pipelines, and deeply buried pipelines. Exposed pipelines are those directly exposed above ground, or those with only simple coverings and not buried in the soil. Exposed pipelines have heating cables on their outer walls to provide active heating. These cables are then wrapped with materials such as rubber-plastic or rigid polyurethane foam to reduce heat loss. Frost-resistant pipelines are those buried below the local frost line. The pipeline itself still has an insulation layer, and localized heating cables may be installed at critical points such as valve wells and outlets as a backup measure against extreme low temperatures. Deeply buried pipelines have a minimum soil cover depth of 0.15m below the frost line. This exceeds the typical frost line depth, entering a relatively stable stratum, where passive insulation relies primarily on geothermal inertia. The frost line refers to a geological layer where rock or soil remains frozen at or below 0°C for at least two consecutive years.

[0086] Example 6 like Figure 2 As shown, based on Embodiment 1, this embodiment provides a specific structure of an antifreeze purified water station 10. The antifreeze purified water station 10 includes a pretreatment system 11 and a posttreatment system 13. An intermediate water tank 12 is provided between the pretreatment system 11 and the posttreatment system 13. The outlet of the posttreatment system 13 is connected to a purified water tank 14. The outlet of the purified water tank 14 is connected to the inlet of the water-using device 80 and the booster pump station 20, respectively.

[0087] Specifically, the pretreatment system 11 mainly includes various filtration devices. Their primary function is to remove large particulate impurities, suspended solids, organic matter, heavy metal ions, etc., from the raw water to protect subsequent precision treatment equipment such as reverse osmosis from damage, while simultaneously improving purification efficiency. Specific pretreatment system 11 equipment may include: a multi-media filtration device: effectively removing large particulate suspended solids and impurities from the water through filter media layers of different particle sizes (such as quartz sand, manganese sand, etc.), protecting subsequent treatment equipment; an activated carbon filtration device: utilizing the adsorption properties of activated carbon to effectively adsorb organic matter, residual chlorine, color, and odors from the water, improving the taste of the water; and a precision filtration device: typically using filter cartridges with micron-sized pores to further remove tiny particles and impurities, improving the water quality entering the desalination section. These pretreatment system 11 devices can be selected and combined according to different raw water qualities and treatment requirements to achieve the best pretreatment effect. The post-treatment system 13 can be an ultrafiltration or reverse osmosis membrane module. A purified water tank 14 is also installed at the rear end of the post-treatment system 13 to store the purified water for timely user access. The water-using device 80 is connected to the purified water tank 14. An intermediate water tank 12 is installed between the pre-treatment system 11 and the post-treatment system 13 to store the intermediate water treated by the pre-treatment system 11. In the antifreeze purified water station 10, a booster pump 65 can be installed in the pipeline according to actual usage needs to ensure normal water flow in the pipeline.

[0088] Example 7 like Figures 10-12 As shown, based on Embodiment 1, this embodiment provides a specific structure of a booster pump station 20. The booster pump station 20 includes a booster pump 65 and a water delivery pipeline 61. A water storage container 21 is connected to the water delivery pipeline 61. The booster pump 65 is installed on the water delivery pipeline 61. The outlet end of the water delivery pipeline 61 is connected to a water supply pipeline and / or a water-using device 80.

[0089] The water storage container 21 is equipped with a water pressure sensor and / or a water level sensor, which is configured to communicate with a control device. The control device is configured to control the switching and / or power of the booster pump 65 based on the water pressure sensor and / or the water level sensor.

[0090] Specifically, the water storage container 21 is installed inside the equipment room 11. The water storage container 21 stores purified water treated by the water treatment component 50, which is then drawn through the water-using device 80 when needed. The water-using device 80 can be a faucet, which can be installed inside or outside the housing 10. It should be noted that when the faucet is installed outside the housing 10, a switch valve can be installed on the water supply pipeline 61, which can be located inside the equipment room 11. After water is drawn, the water in the water supply pipeline 61 remains inside the equipment room 11, preventing water from remaining at the faucet and causing it to freeze and become damaged. The faucet can be made of heat-insulating material to reduce heat loss from the equipment room 11 through the faucet. A booster pump 65 is installed on the water supply pipeline 61 to pressurize the water supply, ensuring that the water in the water storage container 21 can move smoothly along the water supply pipeline 61 and flow out at a certain pressure at the water-using device 80 for normal water access by the user. The water supply pipeline can be part of the pipeline network, used to transport the well water pressurized by the booster pump station 20 to a distant location for use.

[0091] Optionally, a diverter is connected to one end of the water outlet pipe located in the water storage container 21. The inner diameter of the diverter gradually increases in the direction away from the water outlet pipe. The water outlet pipe is detachably connected to the water delivery pipeline 61.

[0092] Specifically, the outlet pipe penetrates one side wall of the water storage container 21, with one end inside the container and the other outside. A flow guide is connected to the end of the outlet pipe in the water storage container 21. This flow guide is funnel-shaped, and the funnel design significantly increases the area of ​​the drain pipe inlet. Compared to a standard straight pipe, the funnel shape collects water from a wider area, allowing water in the storage container 21 to enter the drain pipe more quickly, thus increasing drainage speed. The funnel shape also helps guide water flow smoothly into the drain pipe, reducing turbulence and eddies at the inlet and lowering flow resistance. The end of the outlet pipe outside the storage container 21 has an external thread, which connects to the water supply line 61 via an internal thread connector. The water supply line 61 can be made of UPVC material.

[0093] Optionally, the booster pump station 20 also includes a filter 62 and a sterilizer 68 installed on the water delivery pipeline 61. The filter 62 is located between the booster pump 65 and the water storage container 21, and the sterilizer 68 is located between the booster pump 65 and the water intake device 70.

[0094] Specifically, filter 62 can be a Y-type filter 62, with the head facing downwards. The Y-type filter 62 mainly consists of a valve body, filter screen, filter elements such as a filter basket, flange, flange cover, and fasteners. It is Y-shaped, and its internal components are mostly made of stainless steel, making it sturdy and durable. The filter screen is made into a cylindrical filter basket shape to increase its strength, making it more robust than a single-layer mesh. The flange cover at the lower end of the Y-shaped interface can be unscrewed for easy periodic removal of particulate impurities deposited in the filter basket. Sterilizer 68 can be an ultraviolet sterilizer 68, used for water disinfection. The ultraviolet sterilizer 68 utilizes a specially designed high-efficiency, high-intensity, and long-life ultraviolet UV-C light generator to irradiate flowing water with strong ultraviolet UV-C light to achieve disinfection. When bacteria, viruses, and other microorganisms in the water are irradiated with a certain dose of ultraviolet UV-C light, their cellular DNA and structure are destroyed, preventing cell regeneration, thereby achieving water disinfection and purification. Through filter 62 and sterilizer 68, the water quality is improved.

[0095] Optionally, the booster pump station 20 also includes a pressure gauge 63, a water hammer eliminator 66, and a check valve 67 installed on the water delivery pipeline 61.

[0096] Specifically, pressure gauge 63 facilitates direct observation of the water pressure in the water supply pipeline 61. Water hammer eliminator 66 is a pipeline safety device used to eliminate water hammer phenomena. Inside the water hammer eliminator 66 is a sealed air chamber with a piston at its lower end. When a water hammer wave enters the water hammer eliminator 66, the powerful wave acts on the piston, pushing it towards the air chamber. The piston's stroke depends on the gas pressure within the air chamber and the size of the water hammer wave. Under the combined action of a certain pressure of gas and irregular water hammer, the piston moves up and down, forming a dynamic equilibrium state, effectively eliminating irregular water hammer oscillations and minimizing the destructive force of water hammer. A check valve 67 is installed to prevent backflow of pressurized water from the user's pipeline network. It should be noted that a water meter is also installed on the water supply pipeline 61 to measure the water supply volume.

[0097] Optionally, the inlet and outlet of the booster pump 65 are connected to the water delivery pipeline 61 via flexible rubber joints 64.

[0098] Specifically, by setting up a flexible rubber joint 64, vibration isolation can be achieved, and at the same time, pipeline disassembly and maintenance can be facilitated.

[0099] Optionally, a backup booster pump and water supply pipeline are also provided. Each of the two booster pumps' water supply pipelines 61 is equipped with a switch valve. The inlet end of each of the two water supply pipelines 61 is connected to the outlet pipe. The outlet end of each of the two booster pump stations 20's water supply pipelines 61 is connected to the water supply pipeline and / or the water intake equipment 70. The two booster pump stations 20 are connected to the air pressure water tank 69.

[0100] Specifically, two identical pressurization pump stations 20 are installed inside the insulation room 70. One of the pressurization pump stations 20 serves as a backup, meaning that if one pressurization pump station 20 malfunctions or requires maintenance, the other backup pressurization pump station 20 maintains normal water supply. The water supply pipelines 61 of both pressurization pump stations 20 are connected to the same pressure tank 69. The function of the pressure tank 69 is to reduce the starting frequency of the pressurization pump 65. When water consumption is low, there is no need to start the water pump 41; water is supplied by the pressure tank.

[0101] Optionally, the water storage container 21 is provided with a vent pipe, which is used to connect the water storage container 21 to the equipment room 11.

[0102] Specifically, the vent pipe is installed at the upper end of the water storage container 21. The vent pipe connects the water storage container 21 to the equipment room 11, balances the pressure inside and outside the water storage container 21, keeps the water pressure inside the water storage container 21 at normal pressure, and ensures that the pressure inside the water storage container 21 will not be too high after water is introduced, or that a negative pressure will be formed inside the water storage container 21 after the water is discharged.

[0103] Optionally, an overflow pipe is provided at the top of the water storage container 21 to control the highest liquid level in the water storage container 21, and a vent pipe is provided at the bottom of the water storage container 21 to drain the water in the water storage container 21.

[0104] Specifically, an overflow pipe is installed at the top of the water storage container 21, with the vent pipe positioned above it. This overflow pipe ensures the water level in the container will not exceed its height, allowing excess water to be discharged. A vent pipe is installed at the bottom of the container to drain the water during maintenance and repairs. Insect screens are installed at the outlets of both the overflow and vent pipes to prevent insects from entering the pipe system.

[0105] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
