Description

Technical Field

[0001] This utility model relates to the field of building water supply and drainage pipeline technology, specifically a structure for water supply and drainage pipelines in residential buildings. Background Technology

[0002] Water supply and drainage pipeline engineering refers to pipeline system engineering for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting and discharging industrial wastewater, domestic sewage and rainwater. Residential building water supply and drainage pipeline engineering is an integral part of the residential building water supply and drainage system and plays an important role in the entire water supply and drainage system. Residential building water supply and drainage pipeline engineering is composed of multiple sets of water supply and drainage pipeline structures.

[0003] According to announcement number CN111503393A, a municipal water supply and drainage pipeline connection structure is disclosed, which includes a connector and a sealing unit disposed between the connector and the pipeline. The connector has an axial through hole for fluid to pass through at its center. One end of the connector is a connecting flange, and the other end has an axial mounting hole at its center. The pipeline is installed in the mounting hole and has a sliding fit with the connector.

[0004] The above technical solution, used in pairs, does not require high precision in the distance between the end faces of the two connected pipes. This is particularly suitable for emergency repairs of municipal pipelines, offering high efficiency, rapid connection, high reliability, low labor intensity, and no need to disassemble the pipes. However, the connection point of the two water supply and drainage pipes generally affects the flow of water and drainage, making it easy for debris in the sewage to clog the connection point. This can lead to poor water flow in the residential building's water supply and drainage pipes, increased pressure at the connection point, and potential leakage. Consequently, it affects the function of the water supply and drainage pipe structure in supplying and discharging domestic water and sewage into the residential building. Utility Model Content

The outer surface of each set of first fixing bolts is fixedly connected with an installation ring. The sides of the two sets of installation rings that are close to each other are fixedly connected with a compression spring. The inner wall of each set of compression springs is in contact with the outer surface of the first fixing bolt. The outer surface of each set of first fixing bolts is threadedly connected with a first fixing nut.

[0009] Preferably, reinforcing rings are fixedly connected to the outer surfaces of the first pipe and the second pipe, and the sides of the two reinforcing rings that are close to each other are fixedly connected to the sides of the two connecting flanges that are far from each other.

[0010] By using reinforcing rings to fix the connection between the first and second pipes and the connecting flange, the connection stability of the first and second pipes and the connecting flange is improved.

[0011] Preferably, a first sealing groove is provided at the left end of the first pipe and the right end of the second pipe, and a second sealing groove is provided at both ends of the connecting pipe. A sealing strip is fixedly connected to both sides of each sealing gasket, and the two sets of sealing strips are respectively snapped into the inside of the first sealing groove and the inside of the second sealing groove.

[0012] Two sets of sealing strips are respectively inserted into the inside of the first sealing groove and the inside of the second sealing groove to form a rectangular seal between the sealing gasket and the two connecting flanges and the two mounting flanges, thereby further improving the sealing performance of the connection between the two connecting flanges and the two mounting flanges.

[0013] Preferably, each of the two connecting flanges has a first mounting threaded hole arranged at equal intervals on one side away from each other, and a second mounting threaded hole arranged at equal intervals on one side away from each other.

[0014] The first, second, and third mounting threaded holes facilitate the use of a fixing structure to secure the two gaskets, two connecting flanges, and two mounting flanges, thereby facilitating the installation of the residential building's water supply and drainage pipe structure.

[0015] Preferably, each set of first mounting threaded holes is internally threaded with a second fixing bolt, and the ends of the two sets of second fixing bolts that are close to each other pass through the first mounting threaded hole, the third mounting threaded hole and the second mounting threaded hole in sequence and extend to the outside of the connecting pipe.

[0016] The second fixing bolt passes through the first mounting threaded hole, the third mounting threaded hole, and the second mounting threaded hole to further facilitate the connection of the two gaskets, the two connecting flanges, and the two mounting flanges, thereby improving the connection stability between the first pipe and the second pipe and the connecting pipe.

[0026] A buffer ring is fixed to one end of the compression spring to increase the pressure area between the compression spring and the fixed ring, thereby enabling the compression spring to output elastic force stably.

[0027] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0028] Firstly, this utility model, through the combination of a sealing water-receiving mechanism and a water-spraying alarm mechanism, improves the sealing performance of the residential building's water supply and drainage pipeline structure by installing a connecting pipe between the first and second pipes and a sealing gasket between the connecting flange and the mounting flange. A support rod allows the water storage pipe to be installed outside the connecting pipe, forming a water storage space with the two connecting flanges. This facilitates the collection of water leaking from the connection points of the water supply and drainage pipeline structure, reducing the problem of sewage leakage. A level sensor monitors the water level in the storage pipe; when the maximum set water level is reached, a self-priming pump powers the water to spray water into the connecting pipe through the suction pipe, connecting pipe, and branch spray pipe, reducing blockage at the connection points. Warning lights illuminate the connection, and a signal device sends a signal to the central control room, while a buzzer sounds to alert workers that maintenance is needed on that section of the water supply and drainage pipeline structure. This facilitates the use of this water supply and drainage pipeline structure for the supply and drainage of domestic water and sewage in residential buildings.

[0029] Secondly, this utility model, by providing an installation and reinforcement mechanism, utilizes two fixing rings fixed to the outside of the water storage pipe. The fixing rings are connected to the connecting flange by passing a first fixing bolt through a second threaded hole in the connecting flange and a first threaded hole in the fixing ring. Furthermore, by twisting the first fixing bolt and the first fixing nut, the installation ring compresses the compression spring, accumulating elastic force. This ensures a stable connection between the fixing ring and the connecting flange, thereby firmly fixing the water storage pipe to the outside of the connecting pipe. This reduces the leakage of domestic water and sewage from the water storage pipe and the two connecting flanges into the water storage space, further facilitating the use of this water supply and drainage pipe structure for the supply and discharge of domestic water and sewage from residential buildings.

[0030] The usage methods of this pipeline include:

[0031] S1: In use, when installing this residential building's water supply and drainage pipe structure to supply and discharge domestic water and sewage, firstly, use the connecting flanges fixed to the outer surfaces of the first and second pipes, then install a connecting pipe between the first and second pipes, and fix two mounting flanges to the outside of the connecting pipe. A sealing gasket is placed between the two mounting flanges and the two connecting flanges. A second fixing bolt passes through the first, third, and second mounting threaded holes to further facilitate the connection of the two sealing gaskets, the two connecting flanges, and the two mounting flanges. This improves the connection stability between the first and second pipes and the connecting pipe. Furthermore, using a second fixing nut, the second fixing bolt is stably threaded into the first, third, and second mounting threaded holes, further improving the connection stability between the first and second pipes and the connecting pipe. Both the first and second pipes are connected to the connecting pipes, forming the main body of the residential building's water supply and drainage pipe structure. A sealing gasket placed between them enhances the sealing performance. Two sets of sealing strips are respectively inserted into the first and second sealing grooves to form a rectangular seal between the sealing gasket and the two connecting flanges and two mounting flanges. This further improves the sealing performance of the connection between the two connecting flanges and two mounting flanges, reducing leakage at the connection points of the residential building's water supply and drainage pipe structure. Multiple support rods are fixed to the outer surface of the connecting pipes to install a water storage pipe on the outer surface. The water storage pipe, in conjunction with the two connecting flanges, and secured by a fixing structure, forms a water storage space. This facilitates the collection of water leaking from the connection points of the water supply and drainage pipe structure, reducing the problem of sewage leakage from the water supply and drainage pipe structure.

[0032] S2: In use, first connect the self-priming pump, level sensor, warning light, signal device, and buzzer to their internal power supply. When it is necessary to recycle and reuse water in the storage space and to alarm for leaks at that location, due to prolonged use, some water may leak from the connection between the first and second pipes and the connecting pipe. This water will be stored in a storage space formed by the storage pipe and two connecting flanges. Two level sensors fixed to the bottom wall of the storage pipe monitor the water level in the storage space. When the water level in the storage space reaches the maximum set value of the level sensor, the PLC controller outputs a signal to the self-priming pump. Two sets of connecting legs fix the self-priming pump to the outer surface of the connecting pipe, enabling the self-priming pump to output power stably. Thus, the power provided by the self-priming pump can be used to draw water from the storage space. Water pipes, connecting pipes, and branch spray pipes are secured to the outer surface of the connecting pipes via reinforcing rods. This improves the stability of the leak water reabsorption and reuse structure, allowing water to be re-supplied into the connecting pipes. Pressurized water is used to flush out any blockages within the connecting pipes. Simultaneously, a signal is output from the PLC controller to the warning lights, signal devices, and buzzers. A mounting plate is fixed to the outer surface of the water storage pipe, ensuring the warning lights, signal devices, and buzzers are securely mounted above the water storage pipes. The warning lights illuminate to indicate a leak in the water supply and drainage pipes, while the signal device sends a signal to the residential building's water supply and drainage pipe management control room, indicating the need for manual maintenance. The buzzer alerts nearby personnel to stay away from danger, facilitating the use and maintenance of the water supply and drainage pipe structure for the supply and discharge of domestic water and sewage to the residential building.

[0033] S3: In use, when a stable water storage space consisting of the water storage pipe and two connecting flanges is needed to recover leaked water, the fixing ring fixed to the outer surface of the water storage pipe is first used to contact the two connecting flanges. The first fixing bolt passes through the second threaded hole and the first threaded hole and is threadedly connected to the first fixing nut, thus connecting the fixing ring and the connecting flanges. This allows the water storage space consisting of the water storage pipe and the two connecting flanges to be stable. When the first fixing bolt is turned, the installation ring can squeeze the compression spring outside the first fixing bolt, thereby squeezing the fixing ring and the connecting flange to make the connection between the fixing ring and the connecting flange more stable. A buffer ring is fixed to one end of the compression spring to increase the pressure area between the compression spring and the fixing ring, thereby allowing the compression spring to output elastic force stably. This reduces the problem of leakage caused by increased pressure at the connection position, making it convenient to use this water supply and drainage pipe structure to supply and discharge domestic water and sewage in residential buildings.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] Please see Figure 1-8 Installation method:

[0046] S1: In use, when installing this residential building's water supply and drainage pipe structure to supply and discharge domestic water and sewage, firstly, connecting flanges 201 are fixed to the outer surfaces of the first pipe 1 and the second pipe 5. A connecting pipe 202 is then installed between the first pipe 1 and the second pipe 5, and two mounting flanges 203 are fixed to the outside of the connecting pipe 202. A sealing gasket 204 is placed between the two mounting flanges 203 and the two connecting flanges 201. A second fixing bolt 7 passes through the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10 to further facilitate the connection of the two sealing gaskets 204, the two connecting flanges 201, and the two mounting flanges 203. This improves the connection stability between the first pipe 1, the second pipe 5, and the connecting pipe 202. Furthermore, a second fixing nut 15 is used to securely thread the second fixing bolt 7 into the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10, further enhancing the connection stability between the first pipe 1, the second pipe 5, and the connecting pipe 202. The first pipe 1 and the second pipe 5 are both connected to the connecting pipe 202 to form the main body of the water supply and drainage pipe structure of the residential building. The sealing gasket 204 placed between them is used to improve its sealing performance. Two sets of sealing strips 14 are respectively inserted into the inside of the first sealing groove 9 and the inside of the second sealing groove 11 to form a rectangular seal between the sealing gasket 204 and the two connecting flanges 201 and the two mounting flanges 203. This further improves the sealing performance of the connection between the two connecting flanges 201 and the two mounting flanges 203 and reduces the leakage problem from the connection position of the water supply and drainage pipe structure of the residential building. By fixing multiple support rods 205 on the outer surface of the connecting pipe 202, the water storage pipe 206 is installed on the outer surface of the connecting pipe 202. The water storage pipe 206 cooperates with the two connecting flanges 201 and is connected to the two connecting flanges 201 by a fixing structure to form a water storage space. This facilitates the collection of water leaking from the connection position of the water supply and drainage pipe structure and reduces the problem of sewage leakage from the water supply and drainage pipe structure.

[0047] S2: In use, first connect the self-priming pump 302, level sensor 305, warning light 307, signal device 308, and buzzer 309 to their internal power supply. When it is necessary to recycle and reuse the water in the water storage space and to alarm for leakage at that location, due to prolonged use, some water may leak from the connection between the first pipe 1, the second pipe 5, and the connecting pipe 202. This water will be stored inside the water storage space formed by the water storage pipe 206 and the two connecting flanges 201. Two level sensors 305 fixed to the bottom wall of the water storage pipe 206 are used to monitor the water level of the leaking water in the water storage space. When the water level in the water storage space reaches the maximum water level value set by the level sensor 305, the PLC controller outputs a signal to the self-priming pump 302. Two sets of connecting fixing legs 16 are used to fix the self-priming pump 302 to the outer surface of the connecting pipe 202, enabling the self-priming pump 302 to stably output power. Thus, the power provided by the self-priming pump 302 can be used to make the water in the water storage space flow through the suction pipe 30. 1. The connecting pipe 303 and the spray pipe 304 are fixed to the outer surface of the connecting pipe 202 by the reinforcing rod 18, which improves the stability of the leakage water reabsorption and utilization structure. This allows the water to be re-transported into the interior of the connecting pipe 202 and the pressurized water to flush out any debris that may be clogging the interior of the connecting pipe 202. Simultaneously, the PLC controller outputs a signal to the warning light 307, the signal device 308, and the buzzer 309. The fixing plate 306 is connected to the water storage pipe 206 via the fixing platform 12. The outer surface is fixed, which allows the warning light 307, signal device 308 and buzzer 309 to be firmly fixed above the water storage pipe 206. The warning light 307 emits a warning light to indicate that there is a leak in the water supply and drainage pipe at that location, while the signal device 308 sends a signal to the control room of the residential building's water supply and drainage pipe management to indicate that manual maintenance is required at that location. The buzzer 309 generates a buzzing sound to alert nearby personnel to stay away from danger, thereby facilitating the use and maintenance of the water supply and drainage pipe structure for the supply and discharge of domestic water and sewage in the residential building.

[0048] S3: In use, when a stable water storage space consisting of the water storage pipe 206 and the two connecting flanges 201 is required to recover leaked water, firstly, the fixing ring 401 fixed to the outer surface of the water storage pipe 206 is brought into contact with the two connecting flanges 201. Then, the first fixing bolt 404 passes through the second threaded hole 403 and the first threaded hole 402, and is threadedly connected to the first fixing nut 407, thus connecting the fixing ring 401 to the connecting flanges 201. This allows the water storage space consisting of the water storage pipe 206 and the two connecting flanges 201 to be stably constructed, while the first... When fixing bolt 404, the installation ring 405 can compress the compression spring 406 outside the first fixing bolt 404, thereby compressing the fixing ring 401 and the connecting flange 201 to make the connection between the fixing ring 401 and the connecting flange 201 more stable. A buffer ring 17 is fixed to one end of the compression spring 406 to increase the pressure area between the compression spring 406 and the fixing ring 401, thereby enabling the compression spring 406 to output elastic force stably. This reduces the problem of leakage that may occur due to increased pressure at the connection position, and facilitates the use of this water supply and drainage pipe structure to supply and discharge domestic water and sewage in residential buildings.

[0049] The system includes a first pipe 1, a second pipe 5 located to the left of the first pipe 1, and a sealing water receiving mechanism 2 located on the left side of the first pipe 1 and the right side of the second pipe 5. A water spray alarm mechanism 3 is located both inside and outside the sealing water receiving mechanism 2. Reinforcing mechanisms 4 are located on both sides of the water spray alarm mechanism 3. The sealing water receiving mechanism 2 includes two connecting flanges 201, whose inner walls are fixedly connected to the outer surfaces of the first pipe 1 and the second pipe 5, respectively. The two connecting flanges 201 are positioned close to each other on the same side. There is a connecting pipe 202, and two mounting flanges 203 are fixedly connected to the outer surface of the connecting pipe 202. A sealing gasket 204 is provided on the side of each mounting flange 203 that is far from each other. The side of each sealing gasket 204 that is far from each other contacts the side of each connecting flange 201 that is close to each other. Support rods 205 arranged at equal intervals are fixedly connected to the outer surface of the connecting pipe 202. A water storage pipe 206 is fixedly connected to the ends of several support rods 205 that are far from each other. The side of each connecting flange 201 that is close to each other contacts the side of each water storage pipe 206. The two ends are in contact, and a connecting flange 201 is fixed to the outer surface of the first pipe 1 and the second pipe 5. A connecting pipe 202 is set between the first pipe 1 and the second pipe 5, and two mounting flanges 203 are fixed to the outside of the connecting pipe 202. A sealing gasket 204 is set between the two mounting flanges 203 and the two connecting flanges 201. Thus, the first pipe 1 and the second pipe 5 can be connected to the connecting pipe 202 by using a fixed structure to form the main body of the water supply and drainage pipe structure of the residential building. The sealing gasket 204 set between them improves its sealing performance and reduces the problem of leakage from the connection position of the water supply and drainage pipe structure of the residential building. By fixing multiple support rods 205 to the outer surface of the connecting pipe 202, a water storage pipe 206 is installed on the outer surface of the connecting pipe 202. The water storage pipe 206 cooperates with the two connecting flanges 201, and the water storage pipe 206 is connected to the two connecting flanges 201 by using a fixed structure to form a water storage space. This facilitates the collection of water leaking from the connection position of the water supply and drainage pipe structure and reduces the problem of sewage leakage from the water supply and drainage pipe structure.

[0050] Reinforcing rings 6 are fixedly connected to the outer surfaces of the first pipe 1 and the second pipe 5. The sides of the two reinforcing rings 6 that are close to each other are fixedly connected to the sides of the two connecting flanges 201 that are far apart from each other. The reinforcing rings 6 are used to fix the connection between the first pipe 1 and the second pipe 5 and the connecting flange 201, thereby improving the connection stability between the first pipe 1 and the second pipe 5 and the connecting flange 201.

[0051] A first sealing groove 9 is provided at the left end of the first pipe 1 and the right end of the second pipe 5. A second sealing groove 11 is provided at both ends of the connecting pipe 202. A sealing strip 14 is fixedly connected to both sides of each sealing gasket 204. The two sets of sealing strips 14 are respectively snapped into the inside of the first sealing groove 9 and the inside of the second sealing groove 11. By using the two sets of sealing strips 14 respectively snapped into the inside of the first sealing groove 9 and the inside of the second sealing groove 11, a rectangular seal is formed between the sealing gasket 204 and the two connecting flanges 201 and the two mounting flanges 203, thereby further improving the sealing performance of the connection between the two connecting flanges 201 and the two mounting flanges 203.

[0052] Two connecting flanges 201 each have equidistant first mounting threaded holes 8 on their opposite sides, and two mounting flanges 203 each have equidistant second mounting threaded holes 10 on their opposite sides. Each sealing gasket 204 has equidistant third mounting threaded holes 13 on its left side. Each set of first mounting threaded holes 8 and each set of second mounting threaded holes 10 are connected to the third mounting threaded holes 13. The first mounting threaded holes 8, second mounting threaded holes 10, and third mounting threaded holes 13 allow for easy fixing of the two sealing gaskets 204, the two connecting flanges 201, and the two mounting flanges 203 using a fixing structure, thereby facilitating the installation of the residential building's water supply and drainage pipe structure.

[0053] Each set of first mounting threaded holes 8 has a second fixing bolt 7 threaded inside. The two sets of second fixing bolts 7 have their ends close to each other, passing through the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10 in sequence and extending to the outside of the connecting pipe 202. By passing through the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10, the second fixing bolts 7 can further facilitate the connection of the two sealing gaskets 204, the two connecting flanges 201, and the two mounting flanges 203, thereby improving the connection stability between the first pipe 1, the second pipe 5, and the connecting pipe 202.

[0054] Each set of second fixing bolts 7 has a second fixing nut 15 threadedly connected to its outer surface. The two sets of second fixing nuts 15 are fixedly connected to the opposite sides of the two mounting flanges 203 respectively. Through the second fixing nuts 15, the second fixing bolts 7 are stably threadedly connected to the inside of the first mounting threaded hole 8, the third mounting threaded hole 13 and the second mounting threaded hole 10, which further improves the connection stability between the first pipe 1 and the second pipe 5 and the connecting pipe 202.

[0055] The specific implementation of this embodiment is as follows: When using this residential building water supply and drainage pipe structure to supply and discharge domestic water and sewage, firstly, connecting flanges 201 are fixed to the outer surfaces of the first pipe 1 and the second pipe 5. A connecting pipe 202 is then installed between the first pipe 1 and the second pipe 5, and two mounting flanges 203 are fixed to the outside of the connecting pipe 202. A sealing gasket 204 is installed between the two mounting flanges 203 and the two connecting flanges 201. A second fixing bolt 7 passes through the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10 to further facilitate the connection of the two sealing gaskets 204, the two connecting flanges 201, and the two mounting flanges 203. This improves the connection stability between the first pipe 1, the second pipe 5, and the connecting pipe 202. Furthermore, a second fixing nut 15 is used to stably thread the second fixing bolt 7 into the interior of the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10, further enhancing the connection between the first pipe 1, the second pipe 5, and the connecting pipe 202. Stability is ensured by connecting the first pipe 1 and the second pipe 5 to the connecting pipe 202, forming the main body of the residential building's water supply and drainage pipe structure. A sealing gasket 204 is placed between them to improve sealing. Two sets of sealing strips 14 are respectively inserted into the interior of the first sealing groove 9 and the second sealing groove 11, forming a rectangular seal between the sealing gasket 204 and the two connecting flanges 201 and the two mounting flanges 203. This further improves the sealing performance of the connection between the two connecting flanges 201 and the two mounting flanges 203, reducing leakage at the connection points of the residential building's water supply and drainage pipe structure. Multiple support rods 205 are fixed to the outer surface of the connecting pipe 202, allowing the water storage pipe 206 to be installed on the outer surface of the connecting pipe 202. The water storage pipe 206 cooperates with the two connecting flanges 201, and a fixing structure connects the water storage pipe 206 to the two connecting flanges 201, forming a water storage space. This facilitates the collection of water leaking from the connection points of the water supply and drainage pipe structure, reducing the problem of sewage leakage from the water supply and drainage pipe structure.

[0057] Please see Figure 1-8The water spray alarm mechanism 3 includes a suction pipe 301, with a self-priming pump 302 fixedly connected to the top end of the suction pipe 301. The self-priming pump 302 is a self-priming centrifugal pump, and no foot valve needs to be installed in the pipeline. Before operation, it is only necessary to ensure that a certain amount of priming liquid is stored in the pump body. The model of the self-priming pump 302 is 25FX-13D. The output end of the self-priming pump 302 is fixedly connected to a connecting pipe 303. The output end of the connecting pipe 303 passes through the connecting pipe 202 and extends into the interior of the connecting pipe 202. Two branch spray pipes 304 are fixedly connected to the outer surface of the connecting pipe 303. The output end of each branch spray pipe 304 passes through the connecting pipe 202 and extends into the interior of the connecting pipe 202. The inner bottom wall of the water storage pipe 206 Two liquid level sensors 305 are fixedly connected. Each liquid level sensor 305 is a pressure sensor that measures the liquid level. Each liquid level sensor 305 is connected to the self-priming pump 302 via a PLC controller. A fixing plate 306 is installed above the water storage pipe 206. A warning light 307, a signal device 308, and a buzzer 309 are fixedly connected to the upper surface of the fixing plate 306. The signal device 308 is a device or equipment for sending signals. The buzzer 309 is an integrated electronic sounder powered by DC voltage. The model of the buzzer 309 is LA16J-M. The warning light 307, signal device 308, and buzzer 309 are all connected to the liquid level sensor 302 via a PLC controller. Sensor 305 is connected to the water storage space formed by the water storage pipe 206 and two connecting flanges 201. Due to prolonged use, some water may leak from the connection point between the first pipe 1, the second pipe 5, and the connecting pipe 202. Two level sensors 305 fixed to the bottom wall of the water storage pipe 206 monitor the leaked water level in the storage space. When the water level in the storage space reaches the maximum set value of the level sensor 305, the PLC controller outputs a signal to the self-priming pump 302. This allows the self-priming pump 302 to power the water in the storage space through the suction pipe 301, connecting pipe 303, and distribution pipe. The water spray pipe 304 delivers water back into the connecting pipe 202, using pressurized water to flush out any debris or blockages inside the connecting pipe 202. Simultaneously, the PLC controller outputs a signal to the warning light 307, signal device 308, and buzzer 309. The warning light 307 illuminates to indicate a leak in the water supply and drainage pipe at that location. The signal device 308 sends a signal to the residential building's water supply and drainage pipe management control room, indicating that manual maintenance is required. The buzzer 309 alerts nearby personnel to the danger, facilitating the use and maintenance of the water supply and drainage pipe structure for the supply and discharge of domestic water and sewage from the residential building.

[0058] Two sets of connecting legs 16 are fixedly connected to the outer surface of the self-priming pump 302. The top of each set of connecting legs 16 is fixedly connected to the outer surface of the connecting pipe 202. By using the two sets of connecting legs 16, the self-priming pump 302 is fixed to the outer surface of the connecting pipe 202, thereby enabling the self-priming pump 302 to output power stably.

[0059] A reinforcing rod 18 is fixedly connected to the outer surface of the connecting pipe 303. The end of the reinforcing rod 18 away from the connecting pipe 303 is fixedly connected to the outer surface of the connecting pipe 202. The reinforcing rod 18 is used to fix the connecting pipe 303 to the outer surface of the connecting pipe 202, thereby improving the stability of the leakage water reabsorption and reuse structure.

[0060] A fixing platform 12 is fixedly connected to the bottom surface of the fixing plate 306. The bottom surface of the fixing platform 12 is fixedly connected to the outer surface of the water storage pipe 206. Through the fixing platform 12, the fixing plate 306 can be fixed to the outer surface of the water storage pipe 206, thereby enabling the warning light 307, the signal device 308 and the buzzer 309 to be firmly fixed above the water storage pipe 206.

[0061] The specific implementation of this embodiment is as follows: In use, first connect the self-priming pump 302, liquid level sensor 305, warning light 307, signal device 308, and buzzer 309 to their internal power supply. When it is necessary to recycle and reuse the water inside the storage space, and to alarm for leaks at that location, due to prolonged use, some water may leak from the connection point between the first pipe 1, the second pipe 5, and the connecting pipe 202. This water will be stored until the water storage pipe 206 and the two connecting flanges 201 form a... Inside the water storage space, two level sensors 305 fixed to the bottom wall of the water storage pipe 206 monitor the water level of the leaking water. When the water level in the storage space reaches the maximum water level value set by the level sensor 305, the PLC controller outputs a signal to the self-priming pump 302. Two sets of connecting fixing legs 16 are used to fix the self-priming pump 302 to the outer surface of the connecting pipe 202, enabling the self-priming pump 302 to stably output power. Thus, the power provided by the self-priming pump 302 is used to propel the water in the storage space through... The suction pipe 301, connecting pipe 303, and spray pipe 304 are reinforced by a reinforcing rod 18. The connecting pipe 303 is fixed to the outer surface of the connecting pipe 202, improving the stability of the leaked water reabsorption and reuse structure. This allows the water to be re-poured into the connecting pipe 202, and pressurized water is used to flush away any debris that may be clogging the pipe. Simultaneously, a signal is output from the PLC controller to the warning light 307, signal device 308, and buzzer 309. The fixing plate 306 is connected to the water storage pipe 202 via the fixing platform 12. The outer surface of the 6 is fixed, thereby enabling the warning light 307, signal device 308 and buzzer 309 to be securely fixed above the water storage pipe 206. The warning light 307 emits a warning light to indicate that there is a leak in the water supply and drainage pipe at that location, while the signal device 308 sends a signal to the control room of the residential building's water supply and drainage pipe management to indicate that manual maintenance is required at that location. The buzzer 309 generates a buzzing sound to alert nearby personnel to stay away from danger, thereby facilitating the use and maintenance of the water supply and drainage pipe structure for the supply and discharge of domestic water and sewage in the residential building.

[0062] Example 3

[0063] Please see Figure 1-8The installation and reinforcement mechanism 4 includes two fixing rings 401. The inner wall of each fixing ring 401 is fixedly connected to the outer surface of the water storage pipe 206. The sides of the two connecting flanges 201 that are close to each other are in contact with the sides of the two fixing rings 401 that are far apart from each other. The sides of the two fixing rings 401 that are far apart from each other are provided with first threaded holes 402 arranged at equal intervals. The sides of the two connecting flanges 201 that are far apart from each other are provided with second threaded holes 403 arranged at equal intervals. Each group of first threaded holes 402 is connected to the second threaded holes 403. A first fixing bolt 404 is threadedly connected to the interior of a threaded hole 402 and the interior of each set of second threaded holes 403. The ends of the two sets of first fixing bolts 404, close to each other, pass through the second threaded holes 403 and the first threaded holes 402, extending to the outside of the water storage pipe 206. An installation ring 405 is fixedly connected to the outer surface of each set of first fixing bolts 404. A compression spring 406 is fixedly connected to the side of each set of installation rings 405, close to each other. The inner wall of each set of compression springs 406 contacts the outer surface of the first fixing bolt 404. The outer surface of each of the first fixing bolts 404 is threaded with a first fixing nut 407. The two sets of first fixing nuts 407, with their opposite sides contacting the opposite sides of the two fixing rings 401, respectively. The fixing rings 401, fixed to the outer surface of the water storage pipe 206, contact the two connecting flanges 201. The first fixing bolts 404 can pass through the second threaded hole 403 and the first threaded hole 402, and be threaded with the first fixing nuts 407, thus connecting the fixing rings 401 to the connecting flanges 201. The water storage pipe 206 and the two connecting flanges 201 form a stable water storage space. When the first fixing bolt 404 is twisted, the installation ring 405 can squeeze the compression spring 406 outside the first fixing bolt 404, thereby squeezing the fixing ring 401 and the connecting flange 201 to make the connection between the fixing ring 401 and the connecting flange 201 more stable. This reduces the problem of leakage that may occur due to increased pressure at the connection position, and makes it convenient to use this water supply and drainage pipe structure to supply and discharge domestic water and sewage in residential buildings.

[0064] Each of the two sets of compression springs 406 has a buffer ring 17 fixedly connected to one end of each other. The inner wall of each buffer ring 17 is in contact with the outer surface of the first fixing bolt 404. The side of the two sets of buffer rings 17 that are close to each other is in contact with the side of the two fixing rings 401 that are far apart from each other. The buffer ring 17 is fixed at one end of the compression spring 406 to increase the pressure area between the compression spring 406 and the fixing ring 401, thereby enabling the compression spring 406 to output elastic force stably.

[0065] The specific implementation of this embodiment is as follows: In use, when it is necessary to stably assemble and use the water storage pipe 206 and the two connecting flanges 201 to form a stable water storage space for the recovery of leaked water, firstly, the fixing ring 401 fixed on the outer surface of the water storage pipe 206 is used to make it contact the two connecting flanges 201. Then, the first fixing bolt 404 passes through the second threaded hole 403 and the first threaded hole 402 and is threadedly connected to the first fixing nut 407, thereby connecting the fixing ring 401 to the connecting flanges 201. This allows the water storage space formed by the water storage pipe 206 and the two connecting flanges 201 to be stable. When the first fixing bolt 404 is twisted, the installation ring 405 can squeeze the compression spring 406 outside the first fixing bolt 404, thereby squeezing the fixing ring 401 and the connecting flange 201 to make the connection between the fixing ring 401 and the connecting flange 201 more stable. A buffer ring 17 is fixed to one end of the compression spring 406 to increase the pressure area between the compression spring 406 and the fixing ring 401, thereby enabling the compression spring 406 to output elastic force stably. This reduces the problem of leakage that may occur due to increased pressure at the connection position, and facilitates the use of this water supply and drainage pipe structure to supply and discharge domestic water and sewage in residential buildings.

[0066] The working principle of this utility model is as follows: When using this residential building water supply and drainage pipe structure to supply and discharge domestic water and sewage, firstly, connecting flanges 201 are fixed to the outer surfaces of the first pipe 1 and the second pipe 5. A connecting pipe 202 is then installed between the first pipe 1 and the second pipe 5, and two mounting flanges 203 are fixed to the outside of the connecting pipe 202. A sealing gasket 204 is placed between the two mounting flanges 203 and the two connecting flanges 201. This allows the second fixing bolt 7 to pass through the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10, further facilitating the connection of the two sealing gaskets 204, the two connecting flanges 201, and the two mounting flanges 203. This improves the connection stability between the first pipe 1 and the second pipe 5 and the connecting pipe 202. Furthermore, the second fixing nut 15 securely connects the second fixing bolt 7 to the first mounting threaded hole 8, the third mounting threaded hole 13, and the second mounting threaded hole 10, further enhancing the connection stability between the first pipe 1 and the second pipe 5 and the connecting pipe 202. This ensures that both the first pipe 1 and the second pipe 5 are connected to the connecting pipe 202, forming the main body of the residential building's water supply and drainage pipe structure. The sealing gasket 204 placed between them improves the sealing performance. Two sets of sealing strips 14 are respectively inserted into the first sealing groove 9 and the second sealing groove 11, ensuring that the sealing gasket 204 is properly connected to the two connecting flanges 201 and... A rectangular seal is formed between the two mounting flanges 203, thereby further improving the sealing performance of the connection between the two connecting flanges 201 and the two mounting flanges 203, reducing leakage from the connection point of the water supply and drainage pipe structure in the residential building. Multiple support rods 205 are fixed to the outer surface of the connecting pipe 202 to allow the water storage pipe 206 to be installed on the outer surface of the connecting pipe 202. The water storage pipe 206 is connected to the two connecting flanges 201 through the cooperation of the water storage pipe 206 and the two connecting flanges 201, forming a water storage space. This facilitates the collection of water leaking from the connection point of the water supply and drainage pipe structure, reducing the problem of sewage leakage from the water supply and drainage pipe structure. In use, first, the self-priming... Pump 302, level sensor 305, warning light 307, signal device 308, and buzzer 309 are connected to their internal power supply. When water needs to be recycled and reused in the storage space, and an alarm is triggered for leaks at that location, some water may leak from the connection point between the first pipe 1, the second pipe 5, and the connecting pipe 202 due to prolonged use. This water will be stored in a storage space formed by the storage pipe 206 and the two connecting flanges 201. Two level sensors 305 fixed to the bottom wall of the storage pipe 206 monitor the water level in the storage space. When the water level in the storage space reaches the maximum set value of the level sensor 305, [the system will detect leaks].The PLC controller outputs a signal to the self-priming pump 302. Two sets of connecting and fixing legs 16 are used to fix the self-priming pump 302 to the outer surface of the connecting pipe 202, enabling the self-priming pump 302 to stably output power. This power allows water in the storage space to flow through the suction pipe 301, connecting pipe 303, and spray pipe 304. The reinforcing rod 18 fixes the connecting pipe 303 to the outer surface of the connecting pipe 202, improving the stability of the leaked water reabsorption and utilization structure. This allows the water to be transported back into the connecting pipe 202, and the pressurized water is used to flush out any debris or blockages inside the connecting pipe 202. Simultaneously, the PLC controller outputs a signal to the warning light 307, signal device 308, and buzzer 309. The fixing plate 306 is fixed to the outer surface of the water storage pipe 206 via the fixing platform 12, thus securing the warning light 307, signal device 308, and buzzer 309 firmly above the water storage pipe 206. The warning light 307 illuminates to indicate a leak in the water supply and drainage pipe at that location. The signal device 308 sends a signal to the residential building's water supply and drainage pipe management control room, indicating that manual maintenance is needed. The buzzer 309 emits a sound to alert nearby personnel to stay away from danger, thus facilitating operation. The water supply and drainage pipeline structure is inspected and repaired to supply and discharge domestic water and sewage to residential buildings. When using the pipeline, the water storage pipe 206 and the two connecting flanges 201 are used to stably assemble and recycle leaked water into a stable water storage space. First, the fixing ring 401 fixed to the outer surface of the water storage pipe 206 is brought into contact with the two connecting flanges 201. Then, the first fixing bolt 404 passes through the second threaded hole 403 and the first threaded hole 402, and is threadedly connected to the first fixing nut 407, thus connecting the fixing ring 401 to the connecting flanges 201. This allows the water storage pipe 206 and the two connecting flanges 201 to form a stable water storage space. Inside the water storage space, when the first fixing bolt 404 is twisted, the mounting ring 405 can compress the compression spring 406 outside the first fixing bolt 404, thereby compressing the fixing ring 401 and the connecting flange 201 to make the connection between the fixing ring 401 and the connecting flange 201 more stable. A buffer ring 17 is fixed to one end of the compression spring 406 to increase the pressure area between the compression spring 406 and the fixing ring 401, thus enabling the compression spring 406 to stably output elastic force. This reduces the risk of leakage due to increased pressure at the connection point, facilitating the use of this water supply and drainage pipe structure for the supply and discharge of domestic water and sewage from residential buildings.
