Description

Technical Field

[0001] The present invention relates to the technical field of domestic cold and hot water systems, and particularly to an intelligent three-constant hot water pipeline system for buildings. Background Art

[0002] With the continuous improvement of the requirements for comfort, energy conservation, and intelligence in modern buildings, the traditional hot water supply system is gradually unable to meet the precise needs of modern households and commercial buildings for hot water supply. Especially in aspects such as water temperature control, energy consumption, and water use efficiency, the traditional hot water pipeline system has certain limitations. To solve these problems, the intelligent constant-temperature hot water pipeline system for buildings has emerged, combining advanced intelligent control technology, temperature sensor technology, and energy efficiency optimization solutions, and has become one of the key technologies to improve building comfort and energy conservation performance.

[0003] Currently, the domestic cold and hot water pipelines both adopt a tree-shaped pipe layout method, that is, the main pipeline changes the flow through pipe fittings to reach the end, and then branches and reduces the diameter through tees to each branch water outlet point in the middle. In this way, not only is the water resistance large, but also once two or more water outlets are opened simultaneously, it will inevitably lead to a decrease in the system pressure, and in severe cases, the water flow is so small that it cannot be used, bringing great trouble to people's lives. Especially in winter, the domestic hot water system usually needs to be opened for a long time before hot water comes out, which greatly wastes water resources. Moreover, when the water source is polluted, residents are usually unaware until later, and safety and health cannot be guaranteed. At the same time, the current pipelines all use straight pipes and are then connected through pipe fittings. There are many process joints, which have potential leakage hazards, and the installation efficiency is low. Moreover, when the system is not used for a long time, stagnant water will be generated inside the pipeline, which will produce bacteria or rust, seriously affecting health. Therefore, the proposed invention solves the deficiencies of the above-mentioned technologies and installation processes. Summary of the Invention

[0004] Based on the above existing technical problems, the present invention proposes an intelligent three-constant hot water pipeline system for buildings.

[0005] An intelligent three-constant hot water pipeline system for buildings proposed by the present invention, the system includes a data acquisition and control device, a water control center, a hot water source, a water quality detection device, a flow splitting module, a leakage monitoring module, and a circulation control device. The data acquisition and control device collects the operation data of the water quality detection device, the flow splitting module, the sensor module, the constant-temperature confluence device, the leakage monitoring module, and the circulation control device in real time. The data is transmitted to the central control system or the user terminal by wired or wireless means, and real-time monitoring and feedback are carried out.

[0006] The leakage monitoring module is used to set leakage rules in the system. When the stable water flow duration exceeds a certain time, the system determines that the rule is triggered and generates an alarm. At the same time, the water stop valve is closed to prevent more water from overflowing. If the user has been using water normally for a long time at this time, an alarm will also be triggered. After the alarm is triggered, the user needs to manually send a recovery instruction to resume water use.

[0007] Among them, the flow splitting module includes a hot water splitter and a cold water splitter. Both the output ends of the hot water splitter and the cold water splitter are provided with two or more water outlet points. The input end of the hot water splitter is fixedly connected to the output end of the hot water source, and a constant temperature pipe fitting is installed at the water outlet point of the hot water splitter.

[0008] Among them, the constant temperature confluence device includes a constant temperature confluence collector provided at the output fulcrum of a plurality of the constant temperature pipe fittings. A pipe with a diameter less than 10 mm is used for fixedly connecting the constant temperature pipe fitting and the constant temperature confluence collector. After the hot water is confluenced by the constant temperature confluence collector, it is sent back to the hot water source through the water control center and the circulation control device.

[0009] Among them, the water control center includes an integrated box body, a display screen and a PCB control board. A water purification device communicated with the municipal water pipe is arranged inside the integrated box body.

[0010] Preferably, the water control center further includes a booster pump communicated with the water purification device. The circulation control device includes a circulation pump installed inside the integrated box body. One end of the circulation pump is fixedly connected to the output end of the constant temperature confluence collector through a one-way valve, and the other end of the circulation pump is fixedly connected to the input end of the hot water source.

[0011] Preferably, the water quality detection device includes a pre - water quality monitoring module and a post - water quality monitoring module. The pre - water quality monitoring module monitors the water quality. When the water quality meets the domestic water standard, it is used normally. When the water quality is abnormal, the water control center is started to purify the water quality. The purified water passes through the post - water quality monitoring module. At this time, when the water quality meets the domestic water standard, it is used normally, otherwise an alarm is generated.

[0012] Through the above technical solutions, the combination of the pre - water quality monitoring module and the post - water quality monitoring module can ensure that the water quality is fully detected both at the source and after purification, increasing the safety and reliability of the system. And the pre - water quality monitoring module and the post - water quality monitoring module use TS - 300B turbidity sensors to monitor the water quality of the municipal water.

[0013] Preferably, the water pipe distribution at the water outlet points of the hot water splitter and the cold water splitter adopts the octopus - type pipe laying method, and the water pipes are connected in a one - pipe - through manner.

[0014] Through the above technical solution, the octopus - type pipe - laying method independently branches the water source to the required end through a diverter, solves the problem of pipeline resistance, and the one - pipe - through connection method can reduce the hidden danger of water leakage and improve the installation efficiency and quality.

[0015] Preferably, the water purification device includes a self - cleaning filter disposed inside the integrated box body. The self - cleaning filter is provided with a sewage discharge pipe. The water outlet end of the self - cleaning filter is fixedly communicated with the water inlet end of the booster pump. The sensor module includes a temperature sensor for detecting the water temperature of the water used and a flow sensor for detecting the water flow rate of the water used. The water purification device further includes an impurity pretreatment mechanism and a cleaning mechanism fixedly communicated with the water inlet end of the self - cleaning filter.

[0016] Among them, the impurity pretreatment mechanism preliminarily filters the municipal water entering the self - cleaning filter and crushes impurities during the later backwashing of the self - cleaning filter.

[0017] Among them, the cleaning mechanism performs a cleaning action on the inner wall of the pipeline of the impurity pretreatment mechanism.

[0018] Through the above technical solution, the water purification device regularly performs pulse cleaning on the internal pipeline of the system to ensure that no water scale is generated in the pipeline, and at the same time filters impurities in the municipal pipe network and automatically discharges sewage.

[0019] Preferably, the impurity pretreatment mechanism includes a water inlet pipe fixedly communicated with the self - cleaning filter through a movable interface. The inside of the water inlet pipe is fixedly communicated with the inside of the municipal water pipe. A filter screen is fixedly installed inside one end of the water inlet pipe, and a spherical filter screen is installed on the surface of the filter screen.

[0020] Through the above technical solution, the municipal water flowing into the water inlet pipe from the municipal water pipe contains large - particle impurities such as branches and leaves. In order to avoid reducing the service life of the self - cleaning filter and improve the filtering effect on the municipal water, a filter screen is set in the water inlet pipe to intercept impurities, and at the same time, the spherical filter screen can prevent impurities from adhering to the surface of the filter screen to form a blockage.

[0021] Preferably, the impurity pretreatment mechanism further includes a collection pipe fixedly communicated with the lower end of the water inlet pipe. A crushing motor is fixedly connected to the lower surface of the collection pipe. A crushing shaft is rotatably connected inside the collection pipe. A plurality of sets of crushing blades are arranged on the outer surface of the crushing shaft. One end of the output shaft of the crushing motor is fixedly communicated with one end of the crushing shaft through a coupling. A slag discharge pipe with a one - way valve is fixedly communicated with the lower surface of the collection pipe.

[0022] Through the above technical solution, in order to process the impurities intercepted by the filter screen and avoid affecting the flow rate of the municipal water, the unique surface of the spherical filter screen allows the intercepted impurities to fall into the collection pipe by chance. During the later cleaning of the water purification device, the crushing motor controls the crushing blade to rotate to crush the collected impurities, and then the slag discharge is realized through the slag discharge pipe.

[0023] Preferably, the cleaning mechanism includes a ball valve installed at one end of the water inlet pipe. One end of the ball valve is fixedly communicated with a movable pipe. A cleaning brush is arranged inside the movable pipe, and the surface of the cleaning brush is slidably connected with the surface of the spherical filter screen.

[0024] Through the above technical solution, in order to improve the filtering effect of the filter screen and the spherical filter screen, when the cleaning component is working, the ball valve is opened, so that the movable pipe is communicated with the water inlet pipe. At this time, the cleaning brush inside the movable pipe can extend into the water inlet pipe and contact the surface of the spherical filter screen, and after rotation, the surfaces of the two filter screens are cleaned.

[0025] Preferably, the cleaning mechanism further includes a movable rod moving inside the movable pipe. A rotating motor is installed inside one end of the movable rod close to the ball valve. One end of the output shaft of the rotating motor is fixedly connected with a mounting block through a coupling. One side surface of the mounting block is fixedly connected with one side surface of the cleaning brush through a connecting block. Cleaning blocks are arranged in an annular array on the outer surface of the mounting block, and the outer surfaces of the cleaning blocks are slidably connected with the inner wall of the water inlet pipe.

[0026] Through the above technical solution, the municipal water in the municipal water pipe first enters the water inlet pipe. Therefore, after long-term use, dirt will adhere to the inner wall of the water inlet pipe, which will affect the water quality. In order to clean the water inlet pipe regularly, after the ball valve is opened, the movable rod drives the cleaning brush and the cleaning blocks to enter the water inlet pipe and push forward along the water inlet pipe. Therefore, when the rotating motor drives the mounting block to rotate, the rotation cleaning of the cleaning brush and the rotation of the cleaning blocks arranged in an annular array can be realized, and the inner wall of the water inlet pipe can be scrubbed.

[0027] Preferably, a buffer telescopic rod with a buffer spring is fixedly connected to the lower surface of the cleaning block. One end of the buffer telescopic rod is fixedly connected with the surface of the mounting block. Support rods are symmetrically distributed and fixedly connected to both sides of the lower end surface of the cleaning block. The outer surface of the fixed cylinder of the buffer telescopic rod is fixedly connected with a support ear plate, and the outer surface of the support rod is slidably inserted into the inner wall of the hole of the support ear plate.

[0028] Through the above technical solution, in order to prevent the inner wall of the water inlet pipe from being worn due to the extrusion caused by the rotation cleaning of the cleaning block, the rotation of the cleaning block is buffered and shock-absorbed through the buffer telescopic rod, and the rotating cleaning block is supported by the support rod, so that the cleaning block can adapt to the rotation speed of the rotating motor.

[0029] Preferably, the cleaning mechanism further includes a driving motor fixedly connected to the outer surface of the movable pipe. A regulating screw rod extending into the interior of the movable pipe is fixedly connected to the outer surface of the output shaft of the driving motor, and the outer surface of the regulating screw rod is threadedly sleeved with the interior of the movable rod.

[0030] Through the above technical solution, in order to realize the cleaning action by moving the cleaning block and the cleaning brush inside the water inlet pipe, the driving motor controls the rotation of the regulating screw rod, so that the movable rod linearly moves on the outer surface of the regulating screw rod, thereby realizing the propulsion of the cleaning block and the cleaning brush.

[0031] Preferably, the other group of buffer telescopic rods are fixedly connected to the outer surface of the movable rod in an annular array distribution. A support block is fixedly connected to the upper surface of the other group of buffer telescopic rods, and guide wheels are fixedly connected to the outer surface of the support block in a symmetric distribution. The outer surface of the guide wheels is slidably connected to the inner wall of the movable pipe and the inner wall of the water inlet pipe.

[0032] Through the above technical solution, in order to guide and support the movement of the movable rod and at the same time make it adapt to the internal environment of the movable pipe and the water inlet pipe, the height of the guide wheels can be adjusted telescopically, so that they roll on the inner walls of the movable pipe and the water inlet pipe to complete the guiding and supporting function.

[0033] The beneficial effects in the present invention are as follows:

[0034] 1. By setting the octopus-type pipe laying method, and independently branching the water source to the required ends through the hot water diverter and the cold water diverter, the pipeline resistance problem is solved, and the flow rate of each water outlet point is ensured to be unified. At the same time, in order to solve the problem of unstable water pressure, not only the pipe laying method is changed, but also a pressurization device is added after the municipal household entry. It will actively judge the changes in the system pressure and flow rate, and actively increase the water supply pressure to ensure that the system water pressure is sufficiently balanced.

[0035] 2. The integrated system converges the hot water return water at each end through the constant temperature pipe fittings to the constant temperature manifold, and then returns to the hot water source through the controller and the circulation pump of the water control center to ensure that the instant hot water effect is achieved at each water outlet point at the end. At the same time, after being integrated with the cold water pipeline and the cold water diverter, the hot water pipeline and the hot water diverter, the constant temperature and constant pressure working conditions of the entire system are realized.

[0036] 3. By setting up an impurity pretreatment mechanism, the municipal water in the water inlet pipe of the water control center can be preliminarily filtered to intercept large particulate impurities, and the impurities can be broken during the later pulse flushing for convenient sewage disposal. During the adjustment process, the impurities are intercepted by setting a filter screen in the water inlet pipe. At the same time, the spherical filter screen can prevent the impurities from adhering to the surface of the filter screen to form blockage, so that the intercepted impurities can fall into the collection pipe by chance. During the cleaning of the water purification device later, the crushing motor controls the crushing blade to rotate to crush the collected impurities, and then the slag is discharged through the slag discharge pipe.

[0037] 4. By setting up a cleaning mechanism, the inner wall of the water inlet pipe can be cleaned to avoid the generation of bacteria and rust in the stagnant water inside the pipe. During the adjustment process, after the ball valve is opened, the movable rod drives the cleaning brush and the cleaning block into the water inlet pipe and advances forward along the water inlet pipe. Thus, when the rotating motor drives the installation block to rotate, the cleaning brush can rotate for cleaning, and the cleaning blocks arranged in a circular array can rotate to scrub the inner wall of the water inlet pipe, which is also convenient for flushing the stubborn dirt on the inner wall of the front-end pipe during the pulse flushing.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0056] Referring to Figures 1 - 16 , as Figures 1 - 6 shown, an intelligent three-constant hot water pipeline system for buildings, the system includes a data acquisition and control device, a water control center 9, a hot water source 91, a water quality detection device 131, a sensor module, a flow splitting module, a leakage monitoring module, and a circulation control device. The data acquisition and control device collects the operation data of the water quality detection device 131, the sensor module, the flow splitting module, the constant temperature confluence device, the leakage monitoring module, and the circulation control device in real time, and the data is transmitted to the central control system or the user terminal by wired or wireless means, and real-time monitoring and feedback are carried out.

[0057] The data acquisition and control device collects the data of the water quality detection module, the temperature sensor, and the flow sensor during operation by wired or wireless means, analyzes and judges, and then issues command actions to the booster pump, the water purification device 97, and the circulation control device. At the same time, the system operation data is wirelessly fed back to the data center and the user, so that the water quality of the user's home can be monitored at all times.

[0058] As Figure 6 shown, the leakage monitoring module sets leakage rules for the system. When the stable water flow duration exceeds a certain time, the system determines that the rule is triggered and generates an alarm. At the same time, the water stop valve is closed to avoid more water overflow. If the user has been using water normally for a long time at this time, an alarm will also be triggered. After the alarm is triggered, the user needs to manually issue a recovery command to restore water use.

[0059] Among them, as Figure 1 shown, in order to achieve the functions of constant temperature, constant pressure, and constant flow of the pipeline, the flow splitting module includes a hot water splitter 92 and a cold water splitter 93. The output ends of the hot water splitter 92 and the cold water splitter 93 are each provided with two or more water outlet points. The input end of the hot water splitter 92 is fixedly communicated with the output end of the hot water source 91, and a constant temperature pipe fitting 94 is installed at the water outlet point of the hot water splitter 92;

[0060] Among them, the constant temperature confluence device includes a constant temperature confluence device 95 provided at the output support points of a plurality of the constant temperature pipe fittings 94. The constant temperature pipe fittings 94 and the constant temperature confluence device 95 are fixedly connected by a pipe with a diameter less than 10 mm. The constant temperature confluence device 95 confluences the hot water and then sends it back to the hot water source 91 through the water control center 9 and the circulation control device.

[0061] The integrated system converges the hot water return water at each end through the constant temperature pipe fitting 94 to the constant temperature converger 95, and then returns to the hot water source 91 through the controller and the circulation pump 4 of the water control center 9, so as to ensure that the instant hot water effect is achieved at each end water outlet point. At the same time, after being integrated with the cold water pipeline 931, the cold water diverter 93, the hot water pipeline 921 and the hot water diverter 92, the constant temperature and constant pressure working conditions of the whole system are realized.

[0062] Among them, the water control center 9 includes an integrated box 1, a display screen 11 and a PCB control board 12. A water purification device 97 communicated with the municipal water pipe 2 is arranged inside the integrated box 1.

[0063] The water control center 9 further includes a booster pump 3 communicated with the water purification device 97. The circulation control device includes a circulation pump 4 installed inside the integrated box 1. One end of the circulation pump 4 is fixedly communicated with the output end of the constant temperature converger 95 through a one-way valve 96, and the other end of the circulation pump 4 is fixedly communicated with the input end of the hot water source 91.

[0064] As Figure 4 shown, the water quality detection device 131 includes a pre - water quality monitoring module 13 and a post - water quality monitoring module 14. The pre - water quality monitoring module 13 monitors the water quality. When the water quality meets the domestic water standard, it can be used normally. When the water quality is abnormal, the water control center 9 is started to purify the water quality. The purified water passes through the post - water quality monitoring module 14. At this time, when the water quality meets the domestic water standard, it can be used normally, otherwise an alarm is generated. The combination of the pre - water quality monitoring module 13 and the post - water quality monitoring module 14 can ensure that the water quality is fully detected at the source and after purification, increasing the safety and reliability of the system.

[0065] As Figure 1 shown, the water outlet pipe distribution of the hot water diverter 92 and the cold water diverter 93 adopts the octopus - type pipe laying method, and the pipes are connected in a one - pipe - through manner. The octopus - type pipe laying method branches the water source independently to the required ends through the diverter to solve the pipeline resistance problem. The one - pipe - through connection method can reduce the hidden danger of water leakage and improve the installation efficiency and quality.

[0066] By setting the octopus - type pipe laying method, and branching the water source independently to the required ends through the hot water diverter 92 and the cold water diverter 93, the pipeline resistance problem is solved, and the flow rate of each water outlet point is unified. At the same time, to solve the problem of unstable water pressure, not only the pipe laying method is changed, but also a pressurizing device is added after the municipal water inlet. It will actively judge the changes in system pressure and flow rate and actively increase the water supply pressure to ensure that the system water pressure is sufficiently balanced.

[0067] As Figures 7 - 16As shown in the figure, the water purification device 97 includes a self-cleaning filter 5 disposed inside the integrated box body 1. The self-cleaning filter 5 is provided with a sewage discharge pipe. The water outlet end of the self-cleaning filter 5 is fixedly communicated with the water inlet end of the booster pump 3. Among them, the sensor module includes a temperature sensor for detecting the water temperature of the water used and a flow sensor for detecting the water flow rate of the water used. The water purification device 97 further includes an impurity pretreatment mechanism 6 and a cleaning mechanism 7 fixedly communicated with the water inlet end of the self-cleaning filter 5. The water purification device 97 controls to periodically perform pulse cleaning on the internal pipeline of the system to ensure that no water scale is generated in the pipeline, and at the same time filters the impurities in the municipal water supply network and automatically discharges sewage.

[0068] Among them, the impurity pretreatment mechanism 6 preliminarily filters the municipal water entering the self-cleaning filter 5 and crushes the impurities during the later backwashing of the self-cleaning filter 5.

[0069] The municipal water flowing into the inside of the water inlet pipe 61 from the municipal water pipe 2 contains large-particle impurities such as branches and leaves. In order to avoid reducing the service life of the self-cleaning filter 5 and improve the filtering effect of the municipal water, the impurity pretreatment mechanism 6 includes a water inlet pipe 61 fixedly communicated with the self-cleaning filter 5 through a movable interface. The inside of the water inlet pipe 61 is fixedly communicated with the inside of the municipal water pipe 2. A filter screen 62 is fixedly installed inside one end of the water inlet pipe 61, and a spherical filter screen 63 is installed on the surface of the filter screen 62. The filter screen 62 is arranged in the water inlet pipe 61 to intercept impurities, and at the same time, the spherical filter screen 63 can prevent impurities from adhering to the surface of the filter screen 62 to form a blockage.

[0070] In order to process the impurities intercepted by the filter screen 62 and avoid affecting the flow rate of the municipal water, the impurity pretreatment mechanism 6 further includes a collection pipe 64 fixedly communicated with the lower end of the water inlet pipe 61. A crushing motor 65 is fixedly connected to the lower surface of the collection pipe 64. A crushing shaft 66 is rotatably connected inside the collection pipe 64. A plurality of sets of crushing blades 67 are arranged on the outer surface of the crushing shaft 66. One end of the output shaft of the crushing motor 65 is fixedly communicated with one end of the crushing shaft 66 through a coupling. A slag discharge pipe 68 with a one-way valve 96 is fixedly communicated with the lower surface of the collection pipe 64. Due to the special surface of the spherical filter screen 63, the intercepted impurities fall into the inside of the collection pipe 64 along the trend. During the later cleaning of the water purification device 97, the crushing motor 65 controls the crushing blades 67 to rotate to crush the collected impurities, and then slag discharge treatment is realized through the slag discharge pipe 68.

[0071] By setting up the impurity pretreatment mechanism 6, the municipal water in the water inlet pipe 61 of the water control center 9 can be preliminarily filtered to intercept large particulate impurities, and the impurities can be broken during the later pulse flushing for convenient sewage disposal. During the adjustment process, the impurities are intercepted by setting up a filter screen 62 in the water inlet pipe 61. At the same time, the spherical filter screen 63 can prevent the impurities from adhering to the surface of the filter screen 62 to form a blockage, so that the intercepted impurities fall into the interior of the collection pipe 64 along the trend. During the cleaning of the water purification device 97 later, the crushing motor 65 controls the crushing blade 67 to rotate to crush the collected impurities, and then the slag discharge is realized through the slag discharge pipe 68.

[0072] Among them, the cleaning mechanism 7 performs a cleaning action on the inner wall of the pipeline of the impurity pretreatment mechanism 6.

[0073] In order to improve the filtering effect of the filter screen 62 and the spherical filter screen 63, the cleaning mechanism 7 includes a ball valve 71 installed at one end of the water inlet pipe 61. One end of the ball valve 71 is fixedly communicated with a movable pipe 72. A cleaning brush 73 is arranged inside the movable pipe 72. The surface of the cleaning brush 73 is slidably connected with the surface of the spherical filter screen 63. When the cleaning component is working, the ball valve 71 is opened, so that the movable pipe 72 is communicated with the water inlet pipe 61. At this time, the cleaning brush 73 inside the movable pipe 72 can extend into the interior of the water inlet pipe 61 and contact the surface of the spherical filter screen 63, and the surfaces of the two filter screens can be cleaned after rotation.

[0074] The municipal water in the municipal water pipe 2 first enters the water inlet pipe 61. Therefore, after long-term use, the inner wall of the water inlet pipe 61 will be attached with dirt, which will affect the water quality. In order to regularly self-clean the water inlet pipe 61, the cleaning mechanism 7 further includes a movable rod 74 that moves inside the movable pipe 72. A rotating motor 75 is installed inside one end of the movable rod 74 close to the ball valve 71. One end of the output shaft of the rotating motor 75 is fixedly connected with a mounting block 76 through a coupling. One side surface of the mounting block 76 is fixedly connected with one side surface of the cleaning brush 73 through a connecting block. Cleaning blocks 77 are arranged on the outer surface of the mounting block 76 in an annular array. The outer surface of the cleaning blocks 77 is slidably connected with the inner wall of the water inlet pipe 61. After the ball valve 71 is opened, the movable rod 74 drives the cleaning brush 73 and the cleaning blocks 77 to enter the water inlet pipe 61 and advance forward along the water inlet pipe 61. Therefore, when the rotating motor 75 drives the mounting block 76 to rotate, the cleaning brush 73 can be rotated and cleaned, and the cleaning blocks 77 in the annular array can be rotated to realize the scrubbing of the inner wall of the water inlet pipe 61.

[0075] To prevent the cleaning block 77 from squeezing the water inlet pipe 61 during rotation cleaning and causing wear to its inner wall, a buffer telescopic rod 78 with a buffer spring is fixedly connected to the lower surface of the cleaning block 77. One end of the buffer telescopic rod 78 is fixedly connected to the surface of the mounting block 76. Support rods 79 are symmetrically distributed and fixedly connected to both side surfaces at the lower end of the cleaning block 77. A support ear plate 80 is fixedly connected to the outer surface of the fixed cylinder of the buffer telescopic rod 78. The outer surface of the support rod 79 is slidably inserted into the inner wall of the hole of the support ear plate 80. The rotation of the cleaning block 77 is buffered and shock-absorbed by the buffer telescopic rod 78, and the rotating cleaning block 77 is supported by the support rod 79, enabling the cleaning block 77 to adapt to the rotation speed of the rotating motor 75.

[0076] To enable the cleaning block 77 and the cleaning brush 73 to move inside the water inlet pipe 61 to achieve the cleaning action, the cleaning mechanism 7 further includes a driving motor 81 fixedly connected to the outer surface of the movable pipe 72. A regulating screw rod 82 extending into the interior of the movable pipe 72 is fixedly connected to the outer surface of the output shaft of the driving motor 81. The outer surface of the regulating screw rod 82 is threadedly sleeved with the interior of the movable rod 74. The driving motor 81 controls the rotation of the regulating screw rod 82, causing the movable rod 74 to linearly move on the outer surface of the regulating screw rod 82, thereby enabling the advancement of the cleaning block 77 and the cleaning brush 73.

[0077] To guide and support the movement of the movable rod 74 and enable it to adapt to the internal environment of the movable pipe 72 and the water inlet pipe 61, another group of buffer telescopic rods 78 are fixedly connected to the outer surface of the movable rod 74 in an annular array. A support block 83 is fixedly connected to the upper surface of the other group of buffer telescopic rods 78. Guide wheels 84 are symmetrically distributed and fixedly connected to the outer surface of the support block 83. The outer surface of the guide wheels 84 is slidably connected to the inner wall of the movable pipe 72 and the inner wall of the water inlet pipe 61. The height of the guide wheels 84 can be adjusted telescopically, enabling them to roll on the inner walls of the movable pipe 72 and the water inlet pipe 61 to complete the function of guiding and supporting.

[0078] By providing the cleaning mechanism 7, the inner wall of the water inlet pipe 61 can be cleaned, preventing the generation of bacteria and rust due to stagnant water inside the pipe. During the adjustment process, after the ball valve 71 is opened, the movable rod 74 drives the cleaning brush 73 and the cleaning block 77 into the water inlet pipe 61 and advances along the water inlet pipe 61. Thus, when the rotating motor 75 drives the mounting block 76 to rotate, the cleaning brush 73 can rotate for cleaning, and the cleaning blocks 77 arranged in an annular array can rotate to achieve the scrubbing of the inner wall of the water inlet pipe 61. Furthermore, it is also convenient for flushing stubborn dirt on the inner wall of the front-end pipe during pulsed flushing.

[0079] Working principle: In a specific embodiment of the present invention, the water quality is monitored by the pre - installed water quality monitoring module 13. When the water quality meets the domestic water standard, it can be used normally. When the water quality is abnormal, the water control center 9 is activated to purify the water quality. That is, the municipal water enters the water inlet pipe 61 through the municipal water pipe 2, and then the impurities are intercepted by the filter screen 62. At the same time, the spherical filter screen 63 can prevent impurities from adhering to the surface of the filter screen 62 to form a blockage, so that the intercepted impurities fall into the collection pipe 64 along the trend. Then the preliminarily filtered municipal water is filtered by the self - cleaning filter 5. The booster pump 3 actively judges the changes in system pressure and flow rate and actively increases the water supply pressure. Then the municipal water processed by the water control center 9 is respectively distributed to each water outlet point by the cold water diverter 93 and flows into the hot water source 91. After being heated, it is then distributed to each water outlet point for use by the hot water diverter 92. The constant - temperature pipe fitting 94 at the end water outlet point of the hot water diverter 92 converges the hot water to the constant - temperature converger 95, and then the controller and the circulation pump 4 in the water control center 9 send the water back to the hot water source 91, so as to ensure that hot water can be obtained immediately at the end all the time;

[0080] To ensure the stability of the constant - temperature hot water pipe system, it is necessary to regularly perform pulse cleaning on the internal pipes of the system to prevent scale formation in the pipes. At the same time, filter the impurities in the municipal pipe network and automatically discharge sewage. Therefore, when the system is being cleaned, first, the water outlet end of the self - cleaning filter 5 is closed, and its built - in sewage pipe is opened. Then the self - cleaning filter 5 uses pulsed high - pressure water flow to reverse - flush the filter screen 62;

[0081] While reverse - flushing the filter screen 62, the crushing motor 65 controls the rotation of the crushing shaft 66, so that multiple groups of crushing blades 67 rotate to crush the collected impurities. Then the pulsed water flow flushes the crushed impurities, and discharges the slag through the slag discharge pipe 68;

[0082] At the same time, control the ball valve 71 to open. At this time, the driving motor 81 controls the rotation of the adjusting screw 82, so that the movable rod 74 linearly moves on the outer surface of the adjusting screw 82, thereby realizing the propulsion of the cleaning block 77 and the cleaning brush 73. When the cleaning block 77 is being propelled, another set of buffer telescopic rods 78 adaptively expand and contract in the movable pipe 72 and the water inlet pipe 61, so as to adjust the height of the guide wheel 84, so that it rolls on the inner walls of the movable pipe 72 and the water inlet pipe 61 to complete the guiding and supporting function;

[0083] During the advancement of the cleaning block 77, when the rotating motor 75 drives the mounting block 76 to rotate, the rotation cleaning of the cleaning brush 73 and the rotation of the cleaning blocks 77 in an annular array can be realized, so as to achieve the scrubbing of the inner wall of the water inlet pipe 61 and the washing of the surfaces of the filter screen 62 and the spherical filter screen 63. When the cleaning block 77 rotates, the buffer telescopic rod 78 buffers and dampens the rotation of the cleaning block 77, and the support rod 79 assists in supporting the rotating cleaning block 77, so that the cleaning block 77 can adapt to the rotation speed of the rotating motor 75;

[0084] The impurities cleaned are discharged out of the system together with the pulse flushing, thereby ensuring the filtering effect of the municipal water.

[0085] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
