Description

TECHNICAL FIELD

[0001] The utility model relates to water supply technical field especially relates to a wisdom life water supply system based on inner floating roof water tank. BACKGROUND

[0002] In the modern building field, the residential life water supply system is the key infrastructure to ensure the water demand of residents' daily life. With the continuous improvement of people's demand for life quality and the increasing attention to the rational use of water resources and health protection, the design and performance optimization of the residential life water supply system has become one of the focuses of the drainage field research.

[0003] At present, the common residential life water supply methods mainly have the following three types:

[0004] 1. Roof single water tank water supply, that is, a water tank is arranged on the roof of a building to supply water to all users of the building. This method has the following defects: the water in the water tank is in direct contact with the outside for a long time, which is easy to be invaded by dust, bacteria, algae and other pollutants, affecting the water quality. At the same time, because there is only one water tank, in order to meet the water demand of the whole building, the roof water tank usually needs a large volume, which not only occupies a large space on the roof, affecting the layout of other functions on the roof, but also puts high requirements on the roof structure of the building, which needs special consideration in the design of the building structure, increasing the construction cost.

[0005] 2. Direct water supply of variable frequency pump group, that is, no water tank is arranged on the roof, but a variable frequency pump group is installed in the low-position pump room of the building to directly supply water to the users of each floor of the building. This method has the following defects: the variable frequency pump group is directly arranged at the bottom of the building or the lower floor to pump water upward, which has the following problems: first, the variable frequency pump group needs a large power, and second, the variable frequency pump group needs to be continuously operated to meet the water demand of the users at any time, which will make the energy consumption of the direct water supply of the variable frequency pump group very high, the energy saving effect is poor, and the operation cost is high.

[0006] 3. Direct water absorption of municipal pipeline for pressure water supply, which does not arrange a water tank on the roof, but directly connects the municipal pipe network to use the original pressure of the municipal pipe network to supply water to the users with its own water pump.

[0044] Please refer to Figures 1 to 3 The present application provides a smart life water supply system 100 based on an inner floating roof water tank, comprising:

[0045] A plurality of independent inner floating roof water tank water supply units 10 are dispersedly arranged on the top or inside of the building, each of the inner floating roof water tank water supply units 10 comprises a water tank 11 with an inner floating roof 111 and a water supply control module 12, the inner floating roof 111 can cover the upper surface of water in the water tank 11 and follow the water level change to rise and fall, one of the inner floating roof water tank water supply units 10 is connected with a water consumption area in the building, and the plurality of inner floating roof water tank water supply units 10 supply water to different water consumption areas in the building in a region-by-region manner.

[0046] In the embodiment, each of the inner floating roof water tank water supply units 10 comprises the water tank 11 with the inner floating roof 111 and the water supply control module 12.

[0047] In the embodiment, the water tank 11 is made of corrosion-resistant and non-toxic materials, such as food-grade stainless steel, so that the water tank 11 itself does not have adverse effects on water quality.

[0048] Preferably, the inner floating roof 111 of the water tank 11 is made of high-density polyethylene or hollow titanium alloy.

[0049] The material of the inner floating roof 111 is selected from light, corrosion-resistant and non-toxic materials. In this embodiment, high-density polyethylene (HDPE) is used, which can ensure the buoyancy and sealing effect of the floating roof and will not pollute the water quality. In other embodiments, the inner floating roof 111 is made of hollow titanium alloy material, which not only ensures the water quality but also improves the appearance quality of the water tank.

[0050] The water tank 11 of this embodiment is also provided with a flow guide plate (not shown), which can make the water entering the water tank 11 uniformly distributed. The flow guide plate is usually installed near the water inlet in the water tank 11 and is at an angle with the water tank wall, generally between 45°-60°. When the water enters the water tank 11 from the water inlet, the flow guide plate can guide the water flow to be uniformly distributed to all parts of the water tank, avoiding the water flow directly impacting the wall of the water tank 11 or concentrating in a local area, thereby promoting the uniformity of water mixing and preventing local water quality deterioration.

[0051] The water supply control module 12 in each inner floating roof water tank water supply unit 10 of this embodiment includes a power part and a control part. The power part includes a variable frequency water pump, etc., and the control part includes an automatically controlled valve, a sensor, a control box, etc.

[0052] The water supply system of this embodiment also includes a total control unit 20, as shown in Figure 1 The total control unit 20 is electrically connected with the water supply control modules 12 of the plurality of inner floating roof water tank water supply units 10. The total control unit 20 communicates with the water supply control modules 12, receives the data sent by the water supply control modules 12 and issues control instructions. The total control unit 20 is used for automatic and intelligent control of the entire water supply system 100. The total control unit 20 can be set in the total control room of the community or in the property management office of the community.

[0053] A water supply access unit 30 is arranged at the bottom or ground or underground of the building, connected with the water tanks 11 of the plurality of inner floating roof water tank water supply units 10 through pipelines and electrically connected with the total control unit 20. The water supply access unit 30 is configured to supply water to the water tanks 11 of the inner floating roof water tank water supply units 10. As shown in Figure 1 The input end of the water supply access unit 30 is connected with the municipal pipe network, and the water of the municipal pipe network is accessed into the water supply system 100. At the same time, the water supply access unit 30 is controlled by the total control unit 20, and when the water in the water tank 11 of the inner floating roof water tank water supply unit 10 is insufficient, water is supplied to the water tank 11.

[0054] Specifically, as shown in Figure 2 and Figure 3As shown, the output end of the water tank 11 of this utility model is connected to a pumping pipe 13 and a gravity pipe 14. In this embodiment, the pipe at the output end of the water tank 11 used to supply water to users is divided into a pumping pipe 13 and a gravity pipe 14. Since the vertical distance between users located on the upper floors of the building and the water tank 11 on the roof is close and the pressure difference is small, the upper-floor users of this building (such as...) Figure 2 The water pressure for users on the third floor (near the roof) is insufficient, requiring a water pump to pressurize it. Therefore, a water pump is needed between the water tank 11 and the inlet pipe 16 for the higher-floor users to increase the water supply pressure. Thus, in this embodiment, a pumping pipe 13 is installed at the output end of the water tank 11. The pumping pipe 13 connects to the water pump and then to the inlet pipe 16 for the higher-floor users to provide them with stable water pressure. However, because the vertical distance between the lower-floor users and the rooftop water tank 11 is large, the pressure difference is significant. Therefore, the lower-floor users (such as...) Figure 2 Except for the three users near the top floor, other users can directly rely on gravity for water supply. Therefore, in this embodiment, a gravity pipe 14 is also installed at the output end of the water tank 11. The gravity pipe 14 is directly connected to the inlet pipe 16 of the lower-floor users of the building to supply water directly by gravity. This embodiment divides the water at the output end of the water tank 11 into pumped and direct gravity supply, which greatly reduces the energy consumption of the entire system. This is because only a few users on the upper floors need to be pumped, while the water supply to the lower floors does not require a pump. Thus, the number of pumps in the internal floating roof water tank water supply unit 10 of the entire water supply system 100 is small, and it does not require the variable frequency pump to be turned on for a long time as in the direct water supply method of the variable frequency pump set in the prior art, saving electricity and reducing costs.

[0055] In other embodiments, lower-floor users in the building can connect to both gravity pipes and pumping pipes simultaneously. This way, when the water supply pressure of the gravity pipes is insufficient, the water supply from the pumping pipes can be activated to ensure that the water pressure for lower-floor users remains stable.

[0056] like Figure 3 As shown, the water supply control module 12 in this embodiment specifically includes:

[0057] The water supply pump 121 is connected with the pumping pipe 13 of the water tank 11 at the input end and connected with the indoor pipe 16 at the high level at the output end. In the embodiment, the water supply pump is a variable frequency pump, so that under the control of the total control unit 20, the water pump operation can be adjusted according to the actual water demand, avoiding the overrunning and no-load running of the water supply pump 121. For example, during the low water consumption period, the water supply pump 121 can automatically reduce the rotating speed or stop running, and during the peak water consumption period, the output power is reasonably increased, so that the water supply pump 121 always works in the state of high efficiency and energy saving. Compared with the traditional variable frequency pump group direct water supply system, the water supply control module 12 of the embodiment has more significant energy saving effect, further improving the energy utilization efficiency. This on-demand water supply mode avoids the overrunning of the water supply pump 121, improves the operation efficiency of the water supply pump 121, further saves energy and reduces operation cost. At the same time, it also reduces the damage to the equipment caused by the frequent start and stop of the water supply pump 121, prolongs the service life of the water supply pump 121.

[0058] The sensor group 122 collects water consumption parameters, including the water level, water quality in the water tank 11, and water pressure and flow on the pipe. The sensor group 122 is arranged on the water tank 11 and the pipe. The sensor group 122 of the embodiment can include a water quality sensor, a water level sensor, a water pressure sensor, and a flow sensor, etc. The water quality sensor monitors the water quality data in the water tank 11 in real time, such as the collection and monitoring of indicators such as pH value, dissolved oxygen, turbidity, residual chlorine, etc. The water level sensor collects the water level data in the water tank 11, and the water pressure sensor and the flow sensor collect the water pressure and flow data on the pipe. The sensor group 122 sends the collected water consumption parameters to the water supply adjustment control box 123.

[0059] The water supply adjustment control box 123 of the embodiment is electrically connected with the total control unit 20, the water supply pump 121, and the sensor group 122. The water supply adjustment control box 123 is configured to receive the water consumption parameters collected by the sensor group 122 and send them to the total control unit 20, and control the start and stop of the water supply pump 121 and adjust the power of the water supply pump 121 according to the instructions of the total control unit 20. The water supply adjustment control box 123 is mainly used for the transmission of water consumption parameters and the execution of control instructions, so that the water supply of each area by each inner floating roof water tank water supply unit 10 can be independently controlled.

[0060] The connection between the water supply adjustment control box 123 and the total control unit 20 can be wired connection, such as RS485 bus connection, or wireless connection, such as ZigBee, Wi-Fi, etc.

[0061] Preferably, in the embodiment, the water supply pump 121 shares the common frame base 17 with the water tank 11, wherein the water supply pump 121 is arranged at the lower part of the common frame base 17, and the water tank 11 is arranged at the upper part of the common frame base 17, so as to save the space occupation.

[0062] Preferably, as shown in Figure 3 the embodiment, the water tank 11 is further provided with an automatic sterilization device 15, and the automatic sterilization device 15 is electrically connected with the water supply adjustment control box 123. The automatic sterilization device 15 is used for sterilizing the water in the water tank 11. When the water quality sensor monitors the water quality data in the water tank 11 and sends the water quality data to the total control unit 20 through the water supply adjustment control box 123, the total control unit 20 judges the water quality data. If the water quality exceeds the standard, the sterilization start instruction is sent to the automatic sterilization device 15 through the water supply adjustment control box 123, and then the automatic sterilization device 15 starts the sterilization function to sterilize the water in the water tank 11. In the embodiment, the automatic sterilization device 15 can adopt an automatic control ultraviolet sterilization device.

[0063] Preferably, the top of the water tank 11 is provided with a breathing pipe 112 and an overflow pipe 113. In the embodiment, the top of the water tank 11 is closed, and the breathing pipe 112 is arranged at both sides of the top of the water tank 11. The breathing pipe 112 can guarantee the air pressure balance between the water tank 11 and the outside, so as to smoothly fill water and drain water, and at the same time, avoid foreign matters from entering the water tank 11. The breathing pipe 112 of the embodiment is provided with a filter element to filter the foreign matters in the outside air. The overflow pipe 113 of the embodiment is used for draining water when the water level in the water tank 11 is too high.

[0064] Preferably, as shown in Figure 3 the embodiment, the cross section of the inner floating roof 111 of the water tank 11 is in an inverted U shape. The inverted U-shaped cross section can effectively cover the upper surface of the water in the water tank 11, greatly reduce the contact area between the upper surface of the water in the water tank 11 and the air, avoid the breeding of bacteria, and effectively guarantee the water quality.

[0065] As shown in Figure 1 and Figure 2 the embodiment, the water supply access unit 30 includes a low-position water pool 31 and a water inlet pump set 32. The water inlet pump set 32 is connected with the low-position water pool 31 and the water tank 11 through a pipeline, and the water inlet pump set 32 is further electrically connected with the total control unit 20.

[0066] As shown in Figure 1In this system, the input end of the low-level water tank 31 is connected to the municipal water supply network. The function of the low-level water tank 31 is to store the water provided by the municipal water supply network, preventing fluctuations in the municipal water supply from affecting the stability of the water supply. The inlet pump group 32 is connected to the water tank 11 in each unit through the inlet pipe 33, and an automatically opening and closing electric valve is installed on the inlet pipe 33 near the inlet end of each water tank 11. The inlet pump group 32 can be located near the low-level water tank 31 or in the low-level domestic pump room. The central control unit 20 automatically starts and stops the inlet pump group 32 and opens the electric valve on the inlet pipe 33 based on the water level sensor signal in the water supply tank 11 to provide intelligent water supply to the water tank 11 in each floating roof water tank supply unit 10.

[0067] Preferably, such as Figure 1 As shown, the smart water supply system 100 also includes a user terminal 40 wirelessly connected to the central control unit 20. In this embodiment, the water supply system 100 can equip each user with a user terminal 40, such as a smartphone app or an indoor smart display screen. Users can use the terminal 40 to view their home's water quality, water pressure, current water consumption, and costs in real time. They can also provide feedback when abnormal water quality or pressure is detected, and receive fault alarm information from the system.

[0068] Preferably, the smart water supply system 100 further includes an alarm unit 50 connected to the central control unit 20. The alarm unit 50 can be an alarm message or an audible and visual alarm device. For example, when the water supply system 100 detects a water supply failure at the user end (such as water outage, water quality seriously exceeding standards, etc.), it will automatically send an alarm message to the user terminal to remind the user to take appropriate measures.

[0069] Preferably, the smart water supply system 100 further includes an earthquake monitoring unit 60 connected to the central control unit 20. The earthquake monitoring unit 60 includes an earthquake monitoring sensor connected to the central control unit 20 and a corresponding connection circuit. When the earthquake monitoring sensor detects an earthquake and sends it to the central control unit 20, the water supply system 100 in this embodiment automatically activates an emergency protection program: on the one hand, it shuts down the water pump and water supply valve to prevent water leakage and secondary disasters caused by pipe rupture; on the other hand, it activates the emergency lighting and warning system to provide residents with necessary instructions and assistance in emergency situations.

[0070] Preferably, the total control unit 20 of the embodiment is embedded with intelligent control algorithms to analyze and judge the collected water parameter data. For example, by statistical analysis of water consumption in different time periods, the water consumption peak and valley period is predicted, and the running state of the water supply pump in the inner floating roof water tank water supply unit 10 is adjusted in advance to realize energy saving optimization. In terms of water quality control, the disinfection device is automatically started according to the water quality monitoring data. In terms of maintenance, the total control unit 20 of the system 100 automatically generates a regular inspection and maintenance plan according to the running time, running state and other parameters of the equipment. Maintenance personnel check, clean, maintain and repair the equipment, sensors and the like in the inner floating roof water tank and the water supply module according to the plan to ensure the normal operation of the equipment.

[0071] The water supply system 100 of the embodiment can also be equipped with a remote monitoring and management platform. Management personnel can log in to the platform from anywhere through the Internet to view the real-time running state, historical data records, alarm information and the like of the water supply system 100. At the same time, the management platform of the system 100 also has remote operation functions, such as remotely starting or stopping the water pump, adjusting the pressure setting value, modifying the water quality treatment parameters and the like, to facilitate the remote management and maintenance of the water supply system by the management personnel.

[0072] The intelligent life water supply system 100 based on the inner floating roof water tank of the utility model can be applied to various scenes, as follows:

[0073] Application scenario one: water supply for newly built high-rise residences

[0074] In a newly built high-rise residential area, there are 10 high-rise residential buildings in the area, each building has 30 floors, and each floor has 4 households. The water supply scheme is as follows: the bottom 5 floors are directly supplied by the municipal government, the 6th to 30th floors are supplied by the system, and the top 4 floors of the 6th to 30th floors are supplied by the variable frequency water supply pump in the water supply control module, the other floors are gravity supplied, and the floors with water pressure exceeding 0.2 MPa are provided with branch pressure reducing valves.

[0075] For each residential building, the inner floating roof water tank water supply unit 10 is dispersedly arranged at a suitable position according to the distribution of the house type. For example, for a four-household per elevator house type, an inner floating roof water tank water supply unit 10 is arranged at the top public area of each house type. The volume of the inner floating roof water tank 11 is calculated to be 1 cubic meter. The inner floating roof water tank 11 is made of food-grade stainless steel with a thickness of 3 millimeters, and the inner floating roof 111 is made of high-density polyethylene material with good sealing performance to ensure the isolation of water and air.

[0076] An independent water supply control module 12 is constructed at the location of each water tank 11. The intelligent water supply pump 121 in the water supply control module 12 is selected from a variable frequency water pump with a power of 2.2 kW. The water quality monitoring includes an online water quality monitor (which can monitor pH value, dissolved oxygen, turbidity, residual chlorine and other indicators), and the water treatment device includes an ultraviolet sterilizer (with a power of 30 W). The water supply pipeline adopts PPR pipe material, and the pipe diameter is determined according to the water consumption. The main pipeline has a diameter of DN50, and the branch pipeline has a diameter of DN25.

[0077] A central monitoring host is arranged in the master control unit, which is installed in the community property management center. The central monitoring host connects various sensors, pumps, valves and other devices through an RS485 bus to realize data acquisition and control instruction transmission. At the same time, each household is equipped with a smartphone APP as a user terminal to facilitate residents to view water consumption information and feedback problems.

[0078] Effect: After the water enters the inner floating roof water tank 11, the air is effectively prevented from entering due to the sealing effect of the inner floating roof 111. At the same time, the sealing structure of the inner floating roof water tank reduces the evaporation of water by about 80% compared with the traditional water tank, effectively saving water resources.

[0079] When the top four layers of households use water, the intelligent water supply pump automatically adjusts the speed according to the actual water consumption. During the low water consumption period (such as 2-4 am), the water consumption of most households is very small, and the pump speed is reduced to the lowest operating frequency, reducing energy consumption by about 60% compared with traditional constant-speed water supply. During the water consumption peak period (such as 7-9 pm), the pump automatically increases the speed according to the water pressure and flow demand to ensure that the water pressure of the top four layers of households is stable at about 0.2 MPa, meeting the normal water demand of residents.

[0080] The water quality monitoring and treatment device monitors the water quality in real time, and the sterilizer continuously disinfects and treats the water in the water tank, further ensuring water quality safety.

[0081] The management personnel can check the water level, water quality, pump operating state and other information of each water tank at any time through the remote monitoring platform. For example, through one month of operation data monitoring, it is found that the running current of the water pump of a certain floor of a certain building occasionally fluctuates, and the maintenance personnel are arranged in time to check, and it is found that a small amount of impurities are blocked at the inlet of the water pump. After cleaning, it returns to normal operation, avoiding the further development of equipment failure. When a water tank or an inner floating roof water tank supply unit needs maintenance, such as replacing the ultraviolet lamp tube for disinfection in the water tank, only the water supply valve of the corresponding floor needs to be closed, and the influence range is limited to only a few households of the floor and adjacent floors. The maintenance time is generally not more than 1 hour, while the traditional centralized water supply system may cause the whole building to stop water for several hours or even longer.

[0082] Application scenario two: water supply reconstruction of existing residential areas

[0083] In the renovation project of the water supply system of an existing residential complex, there are 8 residential buildings with 15 floors in the complex. The original low-level water tank + roof water tank water supply method is used. During the renovation, the original low-level water tank is retained, the original roof water tank is removed, and the inner floating roof water tank and water supply module are installed according to the design of the system.

[0084] Water tanks are installed in the space above the balconies of some house types, each with a capacity of 0.5 cubic meters. In order to adapt to the new water tank position, the water supply pipeline is re-laid, using stainless steel corrugated hose to facilitate the bending and installation of the pipeline. The power of the intelligent water supply pump is adjusted to 1.5 kW to meet the water demand of the top four layers of the house type.

[0085] The total control unit is upgraded and renovated in the original community monitoring room, and a wireless communication module (using ZigBee technology) is added to realize wireless data transmission with each water supply unit, reducing wiring cost and construction difficulty. The user terminal is set up in the original community bulletin board with an intelligent display screen. In addition to displaying the water information of the household, it can also scroll the display of the overall water supply situation of the community and water saving propaganda information.

[0086] Application scenario three: water supply in high-end villa complex

[0087] In a high-end villa complex, residents have high requirements for living quality, and the villa house types are diverse and scattered. This water supply system can be designed specifically. The inner floating roof water tank is customized according to the different house types and water demand of the villa, with a volume of 0.5-1 cubic meters, and the inner floating roof is made of more beautiful and corrosion-resistant titanium alloy material, which not only ensures the water quality, but also improves the appearance quality of the water tank.

[0088] The water supply pump in the water supply control module uses a silent pump to further reduce the operating noise, meeting the needs of villa residents for a quiet environment. At the same time, a reverse osmosis membrane water purifier is added to the water quality monitoring and treatment device to deeply purify the water supply, ensuring that residents can directly drink high-quality water.

[0089] The total control unit adds a linkage function with the smart home system. When the smart faucet or smart toilet in the household detects water quality abnormalities, it can automatically send a signal to the total control unit and push an alarm message to the household's mobile phone APP. The user terminal can also be integrated with the smart voice control system in the villa, and the household can query water information and control water supply equipment (such as turning on / off the pump) through voice commands.

[0090] Application scenario four: water supply in commercial buildings

[0091] According to the water consumption characteristics of commercial buildings (including shopping malls, restaurants, office buildings, etc.), the inner floating roof water tank is centrally arranged on the equipment floor of the building, but is divided into multiple independent water supply areas according to different functional areas (such as shopping malls, restaurants, office buildings, etc.). The water tank volume of each area is designed according to the maximum water consumption of the area. The water tank volume of the shopping mall area is 5 cubic meters, the water tank volume of the restaurant area is 3 cubic meters, and the water tank volume of the office building area is 2 cubic meters.

[0092] The water supply pump in the water supply control module uses a high-power, high-lift water pump to meet the water consumption requirements of different floors and different water-consuming equipment (such as the central air conditioning cooling tower of the shopping mall, the dishwashing machine of the restaurant, etc.) of the commercial building. The water quality monitoring and processing device adds special monitoring indicators for commercial water, such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD), to ensure that the commercial water meets environmental protection and health standards.

[0093] The master control unit adds data analysis and statistical functions, which can analyze water consumption data in different time periods (such as weekdays, holidays, daytime, nighttime, etc.) to provide water management decision-making basis for commercial operation. For example, through analysis, it is found that the water consumption of the shopping mall increases significantly during holidays, so the water pump operation strategy can be adjusted in advance to ensure sufficient water supply.

[0094] Application scenario five: residential water supply in earthquake-prone areas

[0095] In the design of a residential water supply system in an earthquake-prone area, in addition to the conventional water supply system design, the emergency protection function is further strengthened. The inner floating roof water tank adopts anti-seismic design, and the reinforcing structure and buffer device of the water tank are increased to ensure the integrity and safety of the water tank in the event of natural disasters such as earthquakes.

[0096] The system adds a seismic monitoring sensor, which automatically starts the emergency protection program when an earthquake is detected. Multiple emergency water supply interfaces are set up in the community and connected to the water tank, and manual water pumping equipment (such as a manual diaphragm pump) is provided. In the event of power failure or water supply system failure due to an earthquake, residents can use the manual water pumping equipment to obtain emergency water from the water tank to meet their basic water needs. At the same time, a linkage mechanism is established with the local emergency rescue departments, so that external rescue forces (such as emergency water supply vehicles) can be obtained in a timely manner when a disaster occurs.

[0097] The intelligent life water supply system 100 based on the inner floating roof water tank has the following advantages:

[0098] 1. Water quality guarantee advantage brought by the inner floating roof water tank structure

[0099] Due to the use of the inner floating roof water tank structure, the water in the water tank has a significantly reduced contact area with air. The inner floating roof closely adheres to the water surface, forming a relatively closed space above the water surface, effectively preventing dust, bacteria, algae spores and other pollutants in the air from entering the water. This structural design significantly reduces the likelihood of microbial growth in the water, greatly improves the stability of the water quality during storage compared to traditional roof water tanks, and can maintain good water quality for a long period of time, reducing the risk of residents' health being threatened due to secondary pollution of water quality. For example, during the summer high-temperature period, the water quality of traditional roof water tanks can quickly deteriorate, causing odors, discoloration and other problems, while the inner floating roof water tank can effectively prevent such situations from occurring.

[0100] The material of the inner floating roof water tank is selected from food-grade stainless steel or other corrosion-resistant materials that meet health standards, which will not release harmful substances into the water, ensuring the purity of the water. At the same time, the sealing structure design of the water tank not only prevents external pollutants from entering, but also reduces water evaporation loss, improving the utilization rate of water resources.

[0101] 2. Multiple advantages of water tank dispersion and nearby water supply

[0102] The method of dispersing water tanks and supplying water nearby reduces the volume of individual water tanks. Compared to large roof water tanks that are centrally located, small-capacity water tanks significantly reduce the pressure on the building roof structure. In the design of building structures, special reinforcement design is not required to bear large water tanks, reducing construction costs. At the same time, it also reduces the risk of long-term potential damage to the roof structure caused by the excessive weight of the water tank, prolonging the service life of the building.

[0103] Nearby water supply (the area near the water tank is supplied by the water tank) significantly reduces the length and complexity of the water supply pipeline. Shorter pipeline length reduces the resistance of water flow in the pipeline. This not only saves energy, but also reduces operating costs and improves the energy utilization efficiency of the entire water supply system. At the same time, the reduction of water pump power makes it easier to eliminate the negative effects of water pump vibration.

[0104] When a water tank or its corresponding water supply module needs maintenance or repair, due to its independent water supply characteristics, only a small number of households corresponding to the water tank will be affected, and the entire building will not be affected. This greatly shortens the maintenance time, reduces the impact on normal life water of residents, improves the reliability of the water supply system and the flexibility of maintenance and management.

[0105] 3. Technical advantages of intelligent water supply control module

[0106] Each water tank is located in a water supply control module that integrates intelligent control technology, which monitors key parameters such as water quality and water pressure in real time through various sensors. This real-time monitoring function can promptly detect abnormal conditions during water supply, such as deteriorating water quality or excessive water pressure fluctuations. Once an anomaly is detected, the intelligent control system can quickly respond by taking appropriate measures, such as starting water purification equipment or adjusting the water pump's operating state, to ensure the safety and stability of water supply. Compared with traditional water supply systems, this can more effectively prevent and solve water supply problems, ensuring the quality and comfort of residents' water use.

[0107] The water supply control module has remote monitoring capabilities, allowing management personnel to view the operating status of each internal floating roof water tank water supply unit through a remote monitoring platform at any time and from anywhere, thanks to internet technology. This breaks down the barriers of time and space, enabling efficient management of the water supply system. Management personnel can obtain equipment operation data in a timely manner, predict potential faults in advance, and develop reasonable maintenance plans, thereby reducing the probability of equipment failure, extending the service life of equipment, reducing maintenance costs, and improving the management efficiency and intelligent level of the entire water supply system.

[0108] The water supply pump in the water supply control module uses variable frequency control technology, which can automatically adjust the speed and output power according to actual water demand. During periods of low water demand, the pump automatically reduces its speed to reduce energy consumption, while during periods of high water demand, it appropriately increases its output power to meet residents' water demand. This on-demand water supply approach avoids excessive operation of the pump, improves the pump's operating efficiency, further saves energy, and reduces operating costs. At the same time, it also reduces damage to the equipment caused by frequent pump start-stop, extending the service life of the pump.

[0109] 4. Advantages of setting internal floating roof water tank water supply units according to house types in terms of standardization, industrialization, and cost control

[0110] Promote the standardization process: Setting water supply modules according to house types provides strong support for the standardization of water supply systems. Water supply units designed for different house types (such as two bathrooms and one kitchen, one bathroom and one kitchen, etc.) can achieve standardization in terms of internal equipment configuration, pipe interface location, operating parameters, etc. For example, for a water supply module for a two-bathroom and one-kitchen house type, knowing the number of floors allows determination of the internal floating roof water tank volume range, intelligent pump power standard, and water quality monitoring and treatment device specifications, etc. This standardized design allows the same water supply module design to be directly used in different building projects as long as the house types are consistent and the number of floors is the same, eliminating the need for complex design calculations and greatly improving design efficiency while reducing the likelihood of design errors. At the same time, standardized water supply modules also facilitate installation by construction personnel, who can ensure the consistency of installation quality by following standard procedures and specifications, further promoting the standardization of the entire water supply system construction process.

[0111] Facilitating Factory Production: Standardized water supply units enable factory production. Because the specifications and parameters of the water supply units are relatively fixed, manufacturers can conduct large-scale prefabrication in the factory. On the production line, the processing, assembly, and equipment debugging of each component can be carried out according to standardized processes, ensuring the stable and reliable quality of each water supply module. Factory production also improves production efficiency and reduces production costs. For example, bulk purchasing of raw materials and components allows for more favorable prices; using automated production equipment and lines reduces labor costs and increases production speed. Moreover, rigorous quality inspection in the factory enables timely detection and resolution of product quality issues, preventing quality defects at the construction site and ensuring the overall quality of the water supply modules.

[0112] 5. Effective Cost Reduction: Costs are reduced in multiple ways. In the design phase, standardized design reduces workload and costs. In production, economies of scale from factory manufacturing lower production costs. During construction, standardized modular installation is simple and quick, shortening the construction cycle and reducing labor costs and equipment rental fees. Furthermore, the modular water supply system, designed according to apartment layouts, is more rational and precise, avoiding over-configuration of equipment, such as avoiding overly powerful pumps or large-capacity tanks for smaller apartments, thus saving on equipment procurement costs. Simultaneously, in later maintenance and management, standardized modular units facilitate operation and repair by maintenance personnel, reducing maintenance costs. For example, maintenance personnel only need to be familiar with the structure and repair methods of a few standard apartment water supply units to quickly handle faults, reducing repair time and spare parts inventory, further lowering maintenance costs.

[0113] 6. Comprehensive advantages brought by the overall system architecture

[0114] The overall system architecture design of this utility model enables all parts to work collaboratively, forming an efficient and intelligent water supply system. The water supply access unit can pre-treat water from the municipal pipe network, providing a guarantee for subsequent water supply stages. The optimized design of the internal floating roof water tank supply unit solves problems such as water pollution, water supply pressure, and energy saving. The central control unit realizes real-time monitoring, intelligent control, and remote management of the entire system, and can also be set up with user terminal interaction devices to improve residents' right to know and participate in the water supply situation.

It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
