Detailed Embodiments

[0020] The following will be combined with the attached Figure 1 - attached Figure 3, the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention and obtain other embodiments without creative labor, and these embodiments are also within the protection scope of the present invention.

[0021] The inventors of this application found that traditional building water supply and drainage systems mainly adopt the method of separately setting up each subsystem (such as water supply and drainage) and operating independently. In the face of emergencies such as fire alarms, they cannot quickly adjust the resource allocation strategy to give priority to ensuring the water supply of fire-fighting facilities. This limitation restricts the ability of the entire building water supply and drainage system to respond to emergencies. Therefore, this application discloses a building water supply and drainage system and a forward design method based on the PLM platform, mainly adopting the following solutions: An embodiment of this application discloses a building water supply and drainage system based on the PLM platform. Refer to Figure 1 , 2 , including a water supply subsystem 1, a drainage subsystem 2, a fire detection module 3, an intelligent control module 4, and a PLM platform integration module 5; the fire detection module 3 is electrically connected to the intelligent control module 4 and is used to detect the fire situation in the building. The fire detection module 3 can adopt a smoke alarm, a temperature sensor, or a flame detector; the intelligent control module 4 is responsible for monitoring and controlling the operating states of the water supply subsystem 1 and the drainage subsystem 2, ensuring the effective allocation and treatment of water resources in the building; the PLM platform integration module 5 is used to realize data integration and management in the design, construction, and operation and maintenance stages.

[0022] Refer to Figure 1 , the water supply subsystem 1 is responsible for the supply of domestic water and fire-fighting water; specifically, the water supply subsystem 1 mainly includes a water supply pipeline 11, a water supply pump 12, a first branch pipeline 13, a second branch pipeline 14, a three-way valve I15, and a water meter 16. The water supply pipeline 11 is connected to the water source, and the water supply pump 12 is installed on the water supply pipeline 11 and is used to supply water into the water supply pipeline 11. The first branch pipeline 13 and the second branch pipeline 14 are both connected to the water supply pipeline 11. The first branch pipeline 13 is connected to the domestic water pipeline in the building and is used to supply water to the domestic water pipeline. The second branch pipeline 14 is connected to the fire-fighting pipeline in the building and is used to supply water to the fire-fighting pipeline in the building.

[0023] Refer to Figure 1 , 2, The three-way valve I15 is installed at the connecting end of the water supply pipeline 11 with the first branch pipeline 13 and the second branch pipeline 14, and is used to regulate the connection between the water supply pipeline and the first branch pipeline 13 or the second branch pipeline 14. Water meters 16 are installed on both the first branch pipeline 13 and the second branch pipeline 14, and are respectively used to monitor the water pressure conditions in the first branch pipeline 13 and the second branch pipeline 14. The water supply pump 12, the three-way valve I15, and each water meter 16 are all electrically connected to the intelligent control module 4.

[0024] Under normal circumstances, the intelligent control module 4 flexibly adjusts the proportion of domestic water and fire-fighting water through the three-way valve I15, so that the water supply pipeline 11 mainly supplies the first branch pipeline 13 to ensure the supply of domestic water. When a fire occurs in the building, the fire detection module 3 detects the fire and sends a fire signal to the intelligent control module 4. At this time, the intelligent control module 4 quickly responds and adjusts the proportion of domestic water and fire-fighting water, increases the supply volume of fire-fighting water, and at the same time reduces the supply volume of domestic water, thereby significantly improving the response ability and safety of the building's water supply and drainage system in case of emergency; the installation of the water meter 16 helps to monitor the water consumption of each branch pipeline in real time, which is convenient for statistical analysis and abnormal detection, so as to comprehensively improve the intelligent level of the building's water supply and drainage system.

[0025] Refer to Figure 1 , The drainage subsystem 2 is responsible for the discharge of domestic sewage and rainwater; specifically, the drainage subsystem 2 includes a sewage pipeline 21, a water collection tank 22, a rainwater pipeline 23, a flow detection module 24, and a valve 25. The sewage pipeline 21 is respectively connected to the building sewage pipeline and the municipal sewage pipeline, and is used to discharge the domestic sewage in the building; the water collection tank 22 is installed on the roof of the building and is used to collect rainwater. The rainwater pipeline 23 is respectively connected to the water collection tank 22 and the sewage pipeline 21, so that the rainwater collected by the water collection tank 22 can be timely introduced into the sewage pipeline 21 through the rainwater pipeline 23 and then discharged by the sewage pipeline 21.

[0026] Refer to Figure 1 、 2 , The flow detection module 24 is installed on the rainwater pipeline 23 and is used to detect the flow in the rainwater pipeline 23. The valve 25 is installed on the rainwater pipeline 23 and is located on the side of the flow detection module 24 close to the sewage pipeline 21. The flow detection module 24 and the valve 25 are both electrically connected to the intelligent control module 4. By setting the flow detection module 24 on the rainwater pipeline 23, the change of rainwater flow can be monitored in real time. Under normal circumstances, the rainwater pipeline 23 is closed through the valve 25; when the flow detection module 24 detects that there is water flow in the rainwater pipeline 23, the valve 25 is controlled to open through the intelligent control module 4, so that the rainwater pipeline 23 can smoothly introduce rainwater into the sewage pipeline 21 and discharge it in time.

[0027] Refer to Figure 1 、3 , a diversion pipe 231 is connected to the rainwater pipeline 23. The connection end of the diversion pipe 231 and the rainwater pipeline 23 is located between the flow detection module 24 and the valve 25. The diversion pipe 231 is connected to a rainwater collection tank 26. A precipitation area 261 and a water collection area 262 are arranged in the rainwater collection tank 26. The precipitation area 261 and the water collection area 262 are separated by a partition plate 263. The diversion pipe 231 is connected to the precipitation area 261. A water passing port 264 is arranged on the partition plate 263, and a water filtering member 265 is arranged at the water passing port 264. Specifically, the water filtering member 265 can adopt a sand filter, filter cotton, filter cloth, or a ceramic filter element, mainly used for filtering sand in water. Arranging the diversion pipe 231 in the rainwater pipeline 23 and connecting it to the rainwater collection tank 26 can introduce part of the rainwater into the rainwater collection tank 26 for storage during rainfall, reduce the amount of rainwater directly discharged into the sewage pipeline 21, and effectively relieve the pressure on the drainage system.

[0028] Refer to Figure 1 , 2 , a three-way valve II 232 is arranged at the connection end of the diversion pipe 231 and the rainwater pipeline 23. A liquid level sensor 266 is arranged in the water collection area 262 of the rainwater collection tank 26, and the liquid level sensor 266 is located above the water passing port 264. Both the three-way valve II 232 and the liquid level sensor 266 are electrically connected to the intelligent control module 4; the liquid level sensor 266 monitors the rainwater storage volume in the rainwater collection tank 26 in real time and feeds the data back to the intelligent control module 4. When there is rainwater passing through the rainwater pipeline 23, the intelligent control module 4 controls the connection between the rainwater pipeline 23 and the diversion pipe 231 through the three-way valve II 232, so that the rainwater can preferentially enter the rainwater collection tank 26 for collection; when the liquid level in the rainwater collection tank 26 reaches a preset value, the rainwater is then introduced into the sewage pipeline 21.

[0029] Refer to Figure 1 , 2 , a water delivery pipeline 27 is connected to the water collection area 262 of the rainwater collection tank 26. The water delivery pipeline 27 is connected to the second branch pipeline 14. A water delivery pump 271 is installed on the water delivery pipeline 27, and the water delivery pump 271 is electrically connected to the intelligent control module 4. By arranging the water delivery pipeline 27 between the rainwater collection tank 26 and the fire pipeline and installing a water delivery pump 271 regulated by the intelligent control module 4 on the water delivery pipeline 27, the treated rainwater can be transported to the fire pipeline as a supplementary water source. This design not only reduces the dependence on external water sources, effectively reduces the operating cost of the system, but also improves the environmental protection and economy of the building water supply and drainage system.

[0030] Refer to Figure 1 , 2, a silt discharge pipe 28 is connected to the bottom position of the sedimentation area 261. The silt discharge pipe 28 is connected to the sewage discharge pipeline 21, and a shut-off valve 281 is provided on the silt discharge pipe 28. The shut-off valve 281 is electrically connected to the intelligent control module 4. By arranging the silt discharge pipe 28 at the bottom position of the sedimentation area 261 and regularly opening the throttle valve, the silt deposited in the sedimentation area 261 can be cleaned in time, improving the intelligent level and maintenance efficiency of the system.

[0031] The implementation principle of a building water supply and drainage system based on the PLM platform in the embodiment of the present application is as follows: The water supply subsystem 1 and the drainage subsystem 2 are clearly divided, responsible for the supply of domestic water and fire water, as well as the discharge of domestic sewage and rainwater respectively, ensuring the effective distribution and treatment of water resources in the building; The coordinated use of the fire detection module 3 and the intelligent control module 4 can quickly respond in case of a fire, reduce the supply volume of domestic water and increase the supply volume of fire water, significantly improving the response ability and safety of the building water supply and drainage system in an emergency; The application of the PLM platform integration module 5 enables the effective integration and management of data in the design, construction and operation and maintenance stages, promoting information sharing and collaboration efficiency improvement in the whole life cycle of the building; The intelligent and integrated management of the building water supply and drainage system is realized.
