Description

Technical Field

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

[0002] As modern buildings continue to demand more comfort, energy saving and intelligence, traditional hot water supply systems are gradually unable to meet the precise needs of modern homes and commercial buildings for hot water supply. In particular, traditional hot water pipe systems have certain limitations in terms of water temperature control, energy consumption and water use efficiency. In order to solve these problems, the building intelligent constant temperature hot water pipe system came into being, 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 saving performance.

[0003] At present, household cold and hot water pipes are all arranged in a tree-like manner, that is, the main pipe flows to the end through pipe fittings, and then is diverted to each branch water outlet point through a tee in the middle. In this way, not only is the water resistance large, but once two or more water outlets are opened simultaneously, the system pressure will inevitably drop. In severe cases, the water flow is so small that it cannot be used, which brings great trouble to people's lives. Especially in winter, the household hot water system usually needs to be turned on for a long time before hot water can be produced, which greatly wastes water resources. Moreover, when the water source is polluted, residents are only aware of it later, and safety and health cannot be guaranteed. At the same time, the current pipelines all use straight pipes and are connected by pipe fittings. Most of the process joints have the risk of water leakage, and the installation efficiency is low. Moreover, if the system is not used for a long time, the stagnant water inside the pipeline will produce bacteria or rust, which seriously affects health. Therefore, the invention solves the shortcomings of the above-mentioned technical and installation process problems. Summary of the invention

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

[0005] The present invention proposes an intelligent three-constant hot water pipe system for a building, the system comprising a data acquisition control device, a water control center, a hot water source, a water quality detection device, a diversion module, a leakage monitoring module and a circulation control device, the data acquisition control device collects the operating data of the water quality detection device, the diversion 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 end by wired or wireless means, and real-time monitoring and feedback are performed.

[0006] The water leakage monitoring module is a system-set water leakage rule. When the water flow is stable for more than a certain period of 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 uses 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 resume water use.

The constant temperature confluence converges the hot water and sends it back to the hot water source through the water control center and the circulation control device.

[0008] The water control center includes an integrated box, a display screen and a PCB control board, and a water purification device connected to a municipal water pipe is arranged inside the integrated box.

[0010] Preferably, the water quality detection device includes a front water quality monitoring module and a rear water quality monitoring module. The front water quality monitoring module monitors the water quality. When the water quality reaches the standard for domestic water, it is used normally. When the water quality is abnormal, the water control center is started to purify the water. The purified water passes through the rear water quality monitoring module. At this time, when the water quality reaches the standard for domestic water, it is used normally. Otherwise, an alarm is generated.

[0011] Through the above technical solution, the combination of pre- and post-water quality monitoring modules can ensure that the water quality is fully tested both at the source and after purification, increasing the safety and reliability of the system. The pre- and post-water quality monitoring modules use TS-300B turbidity sensors to monitor the water quality of municipal water.

[0012] Preferably, the water pipes at the water outlets of the hot water diverter and the cold water diverter are distributed in an octopus-style pipe layout, and the water pipes are connected in a one-pipe-to-the-bottom manner.

[0013] Through the above technical solution, the octopus-style pipe layout method is to branch the water source independently to the required end through a diverter to solve the pipeline resistance problem. The one-pipe connection to the end can reduce the risk of water leakage and improve installation efficiency and quality.

[0014] Preferably, the water purification device includes a self-cleaning filter arranged inside the integrated box, the self-cleaning filter has a sewage pipe, the water outlet end of the self-cleaning filter is fixedly connected to the water inlet end of the boosting 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, and the water purification device also includes an impurity pretreatment mechanism and a cleaning mechanism fixedly connected to the water inlet end of the self-cleaning filter.

[0015] The impurity pretreatment mechanism performs preliminary filtration on the municipal water entering the self-cleaning filter, and crushes the impurities during the backwashing of the self-cleaning filter at a later stage.

[0016] Wherein, the cleaning mechanism performs a cleaning action on the inner wall of the pipeline of the impurity pretreatment mechanism.

[0017] Through the above technical solution, the water purification device controls the system to periodically perform pulse cleaning on the internal pipes to ensure that no scale is generated in the pipes, while at the same time filtering impurities in the municipal pipe network and automatically discharging sewage.

[0018] Preferably, the impurity pretreatment mechanism includes a water inlet pipe fixedly connected to the self-cleaning filter through a movable interface, the interior of the water inlet pipe is fixedly connected to the interior of the municipal water pipe, a filter net is fixedly installed inside one end of the water inlet pipe, and a spherical filter net is installed on the surface of the filter net.

[0019] Through the above technical solution, the municipal water flowing into the water inlet pipe contains large particles of impurities such as branches and leaves. In order to avoid reducing the service life of the self-cleaning filter and improve the filtering effect of municipal water, a filter net is set in the water inlet pipe to intercept impurities. At the same time, the spherical filter net can prevent impurities from adhering to the surface of the filter net to form blockage.

[0020] Preferably, the impurity pretreatment mechanism also includes a collecting pipe fixedly connected to the lower end of the water inlet pipe, the lower surface of the collecting pipe is fixedly connected to a crushing motor, the inside of the collecting pipe is rotatably connected to a crushing shaft, the outer surface of the crushing shaft is provided with multiple groups of crushing blades, one end of the output shaft of the crushing motor is fixedly connected to one end of the crushing shaft through a coupling, and the lower surface of the collecting pipe is fixedly connected to a slag discharge pipe with a one-way valve.

[0021] Through the above technical scheme, in order to process the impurities intercepted by the filter and avoid affecting the flow rate of municipal water, the unique surface of the spherical filter allows the impurities intercepted by it to fall into the collection pipe. When the water purification device is cleaned in the later stage, 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.

[0022] Preferably, the cleaning mechanism comprises a ball valve installed at one end of the water inlet pipe, one end of the ball valve is fixedly connected to a movable tube, a cleaning brush is arranged inside the movable tube, and the surface of the cleaning brush is slidably connected to the surface of the spherical filter.

[0023] 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 to connect the movable tube with the water inlet pipe. At this time, the cleaning brush inside the movable tube can extend to the inside of the water inlet pipe and contact the surface of the spherical filter screen, so that it rotates to complete the cleaning of the surfaces of the two filters.

[0024] Preferably, the cleaning mechanism also includes a movable rod which moves inside the movable tube, 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 to a mounting block via a coupling, one side surface of the mounting block is fixedly connected to one side surface of the cleaning brush via a connecting block, the outer surface of the mounting block is provided with cleaning blocks distributed in a circular array, and the outer surface of the cleaning block is slidably connected to the inner wall of the water inlet pipe.

[0025] Through the above technical scheme, 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, thereby affecting the water quality. In order to regularly realize self-cleaning of the water inlet pipe, after the ball valve is opened, the movable rod drives the cleaning brush and the cleaning block into the water inlet pipe and moves forward along the water inlet pipe. When the rotating motor drives the mounting block to rotate, the cleaning brush can be rotated and cleaned, and the cleaning blocks in the circular array can be rotated to realize the scrubbing of the inner wall of the water inlet pipe.

[0026] 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 to the surface of the mounting block, and support rods are symmetrically distributed and fixedly connected to the two side surfaces of the lower end of the cleaning block, and a support ear plate is fixedly connected to the outer surface of the fixed tube of the buffer telescopic rod, and the outer surface of the support rod is slidably plugged into the inner wall of the hole of the support ear plate.

[0027] Through the above technical scheme, in order to avoid the cleaning block from squeezing the water inlet pipe and causing wear on its inner wall when rotating for cleaning, the rotation of the cleaning block is buffered and damped by a buffer telescopic rod, and the rotating cleaning block is auxiliary supported by a support rod, so that the cleaning block adapts to the rotation speed of the rotating motor.

[0028] Preferably, the cleaning mechanism also includes a driving motor fixedly connected to the outer surface of the movable tube, the outer surface of the output shaft of the driving motor is fixedly connected to an adjusting screw extending into the interior of the movable tube, and the outer surface of the adjusting screw is sleeved with the internal thread of the movable rod.

[0029] Through the above technical solution, in order to realize the movement of the cleaning block and the cleaning brush inside the water inlet pipe to achieve the cleaning action, the driving motor controls the rotation of the adjusting screw so that the movable rod moves linearly on the outer surface of the adjusting screw, thereby realizing the advancement of the cleaning block and the cleaning brush.

[0030] Preferably, another group of the buffer telescopic rods are distributed in a circular array and fixedly connected to the outer surface of the movable rod, and the upper surface of another group of the buffer telescopic rods is fixedly connected to a support block, and the outer surface of the support block is symmetrically distributed and fixedly connected to a guide wheel, and the outer surface of the guide wheel is slidably connected to the inner wall of the movable tube and the inner wall of the water inlet pipe.

[0031] Through the above technical solution, in order to guide and support the movement of the movable rod and make it adapt to the internal environment of the movable tube and the water inlet pipe, the height of the guide wheel can be telescopically adjusted so that it can roll on the inner walls of the movable tube and the water inlet pipe to complete the function of guiding and supporting.

[0032] The beneficial effects of the present invention are: 1. By setting up an octopus-style pipe layout and independently branching the water source to the required end through hot water diverters and cold water diverters, the problem of pipeline resistance is solved and the flow rate of each water outlet is guaranteed to be uniform. At the same time, in order to solve the problem of unstable water pressure, not only the pipe layout method is changed, but also a booster device is added after the municipal water enters the household. It will actively judge the changes in system pressure and flow, and actively increase the water supply pressure to ensure that the system water pressure is sufficiently balanced.

[0033] 2. The integrated system returns the hot water from each end to the constant temperature manifold through constant temperature pipe fittings, and then returns to the hot water source through the controller and circulation pump of the water control center to ensure that each water outlet can achieve the effect of instant heating. At the same time, after integration with the cold water pipeline and cold water manifold, hot water pipeline and hot water manifold, the constant temperature and constant pressure working conditions of the entire system are achieved.

[0034] 3. By setting up an impurity pretreatment mechanism, the municipal water in the water inlet pipe of the water control center can be initially filtered to intercept large particles of impurities, and the impurities can be broken during the subsequent pulse flushing to facilitate sewage treatment. During the adjustment process, impurities are intercepted by setting a filter in the water inlet pipe. At the same time, the spherical filter can prevent impurities from adhering to the surface of the filter to form a blockage, so that the impurities intercepted fall into the collection pipe. When the water purification device is cleaned in the later stage, 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.

[0035] 4. By setting up a cleaning mechanism, the inner wall of the water inlet pipe can be cleaned to avoid bacteria and rust caused by 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 pushes forward along the water inlet pipe. When the rotating motor drives the mounting block to rotate, the cleaning brush can be rotated and cleaned, and the cleaning blocks in the circular array can be rotated to scrub the inner wall of the water inlet pipe, which is also convenient for flushing stubborn dirt on the inner wall of the front pipe during pulse flushing.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-Figure 16 ,like Figure 1-Figure 6As shown, a building intelligent three-constant hot water pipe system includes a data acquisition control device, a water control center 9, a hot water source 91, a water quality detection device 131, a sensor module, a diversion module, a leakage monitoring module and a circulation control device. The data acquisition control device collects the operating data of the water quality detection device 131, the sensor module, the diversion 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 end by wired or wireless means, and real-time monitoring and feedback are performed.

[0040] The data acquisition control device collects the data of the water quality detection module, temperature sensor, and flow sensor in operation by wired or wireless means, and after analysis and judgment, it implements command actions on the booster pump, water purification device 97, and circulation control device. At the same time, the system operation data is fed back to the data center and users by wireless, so that the quality of user's home water can be monitored at all times.

[0041] like Figure 6 As shown, the water leakage monitoring module is a system-set water leakage rule. When the water flow is stable for more than a certain period of 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 uses 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 resume water use.

[0042] Among them, Figure 1 As shown, in order to realize the functions of constant temperature, constant pressure and constant flow of the pipeline, the diverter module includes a hot water diverter 92 and a cold water diverter 93. The output ends of the hot water diverter 92 and the cold water diverter 93 are both provided with two or more water outlets. The input end of the hot water diverter 92 is fixedly connected with the output end of the hot water source 91. A constant temperature pipe 94 is installed on the water outlet of the hot water diverter 92. Among them, the constant temperature confluence device includes a constant temperature confluence 95 arranged at the output fulcrum of multiple constant temperature pipe fittings 94, and the constant temperature confluence 95 is fixedly connected with a pipe with a diameter less than 10 mm. The constant temperature confluence 95 converges the hot water and sends it back to the hot water source 91 through the water control center 9 and the circulation control device.

[0043] The integrated system returns the hot water from each end to the constant temperature concentrator 95 through the constant temperature pipe fitting 94, and then returns to the hot water source 91 through the controller and circulation pump 4 of the water control center 9, so as to ensure that each end water outlet can achieve the effect of instant heating. At the same time, after integration with the cold water pipeline 931 and 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.

[0044] 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 connected to the municipal water pipe 2 is arranged inside the integrated box 1.

[0045] The water control center 9 also includes a booster pump 3 connected to the water purification device 97, and the circulation control device includes a circulation pump 4 installed inside the integrated box 1. One end of the circulation pump 4 is fixedly connected to the output end of the constant temperature flow collector 95 through a one-way valve 96, and the other end of the circulation pump 4 is fixedly connected to the input end of the hot water source 91.

[0046] like Figure 4 As shown, the water quality detection device 131 includes a front water quality monitoring module 13 and a rear water quality monitoring module 14. The front water quality monitoring module 13 monitors the water quality. When the water quality reaches the standard for domestic water, it can be used normally. When the water quality is abnormal, the water control center 9 is started to purify the water. The purified water passes through the rear water quality monitoring module 14. At this time, when the water quality reaches the standard for domestic water, it can be used normally. Otherwise, an alarm is generated. The combination of the front and rear water quality monitoring modules 14 can ensure that the water quality is fully detected at the source and after purification, thereby increasing the safety and reliability of the system.

[0047] like Figure 1 As shown, the water pipes at the outlets of the hot water diverter 92 and the cold water diverter 93 are distributed in an octopus-style manner, and the water pipes are connected in a one-pipe-to-the-end manner. The octopus-style pipe layout is to independently branch the water source to the required end through the diverter to solve the problem of pipeline resistance. The one-pipe-to-the-end connection can reduce the risk of water leakage and improve installation efficiency and quality.

[0048] By setting up an octopus-style pipe layout and independently branching the water source to the required end 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 is guaranteed to be uniform. At the same time, in order to solve the problem of unstable water pressure, not only the pipe layout method is changed, but also a booster device is added after the municipal water enters the household. It will actively judge the changes in system pressure and flow, and actively increase the water supply pressure to ensure that the system water pressure is sufficiently balanced.

[0049] like Figure 7-Figure 16 As shown, the water purification device 97 includes a self-cleaning filter 5 arranged inside the integrated box 1, the self-cleaning filter 5 is provided with a sewage pipe, the water outlet end of the self-cleaning filter 5 is fixedly connected to the water inlet end of the booster pump 3, wherein 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, the water purification device 97 also includes an impurity pretreatment mechanism 6 and a cleaning mechanism 7 fixedly connected to the water inlet end of the self-cleaning filter 5, the water purification device 97 controls the system to periodically pulse clean the internal pipes to ensure that the pipes do not generate scale, and at the same time filters the impurities in the municipal pipe network and automatically discharges sewage.

[0050] The impurity pretreatment mechanism 6 performs preliminary filtration on the municipal water entering the self-cleaning filter 5 and crushes the impurities during the backwashing of the self-cleaning filter 5 at a later stage.

[0051] The municipal water flowing into the water inlet pipe 61 from the municipal water pipe 2 contains large particles of 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 an inlet pipe 61 fixedly connected to the self-cleaning filter 5 through a movable interface. The interior of the water inlet pipe 61 is fixedly connected to the interior of the municipal water pipe 2. A filter screen 62 is fixedly installed at one end of the water inlet pipe 61. 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. 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.

[0052] In order to process the impurities intercepted by the filter screen 62 and avoid affecting the flow rate of municipal water, the impurity pretreatment mechanism 6 also includes a collecting pipe 64 fixedly connected to the lower end of the water inlet pipe 61, and the lower surface of the collecting pipe 64 is fixedly connected to a crushing motor 65, and the inside of the collecting pipe 64 is rotatably connected to a crushing shaft 66, and the outer surface of the crushing shaft 66 is provided with a plurality of crushing blades 67. One end of the output shaft of the crushing motor 65 is fixedly connected to one end of the crushing shaft 66 through a coupling, and the lower surface of the collecting pipe 64 is fixedly connected to a slag discharge pipe 68 with a one-way valve 96. The unique surface of the spherical filter screen 63 allows the impurities intercepted by it to fall into the collecting pipe 64. When the water purification device 97 is cleaned in the later stage, 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.

[0053] 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 initially filtered to intercept large particles of impurities, and the impurities can be broken during the subsequent pulse flushing to facilitate sewage treatment. During the adjustment process, the impurities are intercepted by setting a filter screen 62 in the water inlet pipe 61. 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 impurities intercepted fall into the collection pipe 64. When the water purification device 97 is cleaned in the later stage, the crushing motor 65 controls the crushing blade 67 to rotate to crush the collected impurities, and then the slag discharge treatment is realized through the slag discharge pipe 68.

[0054] The cleaning mechanism 7 cleans the inner wall of the pipeline of the impurity pretreatment mechanism 6 .

[0055] 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, and one end of the ball valve 71 is fixedly connected to a movable tube 72, and a cleaning brush 73 is arranged inside the movable tube 72. The surface of the cleaning brush 73 is slidably connected to the surface of the spherical filter screen 63. When the cleaning component is working, the ball valve 71 is opened to connect the movable tube 72 with the water inlet pipe 61. At this time, the cleaning brush 73 inside the movable tube 72 can extend to the inside of the water inlet pipe 61 and contact the surface of the spherical filter screen 63, so that it rotates to complete the cleaning of the surfaces of the two filters.

[0056] The municipal water in the municipal water pipe 2 first enters the water inlet pipe 61. Therefore, after long-term use, dirt will adhere to the inner wall of the water inlet pipe 61, thereby affecting the water quality. In order to regularly realize self-cleaning of the water inlet pipe 61, the cleaning mechanism 7 also includes a movable rod 74 that moves inside the movable tube 72. A rotating motor 75 is installed inside the 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 to a mounting block 76 through a coupling. One side surface of the mounting block 76 is connected to the cleaning brush through the connecting block. One side surface of 73 is fixedly connected, and the outer surface of the mounting block 76 is provided with cleaning blocks 77 in a circular array. The outer surface of the cleaning block 77 is slidably connected to 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 block 77 to enter the water inlet pipe 61 and move forward along the water inlet pipe 61. When the rotating motor 75 drives the mounting block 76 to rotate, the cleaning brush 73 can be rotated for cleaning and the cleaning blocks 77 in the circular array can be rotated to achieve scrubbing of the inner wall of the water inlet pipe 61.

[0057] In order to avoid the water inlet pipe 61 being squeezed and the inner wall thereof being worn due to the cleaning block 77 rotating for cleaning, 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, and support rods 79 are symmetrically distributed and fixedly connected to the two side surfaces of the lower end of the cleaning block 77, and a support ear plate 80 is fixedly connected to the outer surface of the fixed cylinder of the buffer telescopic rod 78, and the outer surface of the support rod 79 is slidably plugged into the inner wall of the hole of the support ear plate 80, and the rotation of the cleaning block 77 is buffered and damped by the buffer telescopic rod 78, and the rotating cleaning block 77 is auxiliary supported by the support rod 79, so that the cleaning block 77 can adapt to the rotation speed of the rotating motor 75.

[0058] In order 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 also includes a driving motor 81 fixedly connected to the outer surface of the movable tube 72, and the outer surface of the output shaft of the driving motor 81 is fixedly connected to an adjusting screw 82 extending to the inside of the movable tube 72, and the outer surface of the adjusting screw 82 is sleeved with the internal thread of the movable rod 74. The driving motor 81 controls the rotation of the adjusting screw 82, so that the movable rod 74 moves linearly on the outer surface of the adjusting screw 82, thereby realizing the advancement of the cleaning block 77 and the cleaning brush 73.

[0059] In order to guide and support the movement of the movable rod 74 and make it adapt to the internal environment of the movable tube 72 and the water inlet pipe 61, another group of buffer telescopic rods 78 are distributed in a circular array and fixedly connected to the outer surface of the movable rod 74, and the upper surface of the other group of buffer telescopic rods 78 is fixedly connected to a support block 83, and the outer surface of the support block 83 is symmetrically distributed and fixedly connected to a guide wheel 84, and the outer surface of the guide wheel 84 is slidably connected to the inner wall of the movable tube 72 and the inner wall of the water inlet pipe 61, and the height of the guide wheel 84 can be telescopically adjusted so that it can roll on the inner wall of the movable tube 72 and the water inlet pipe 61 to complete the function of guiding and supporting.

[0060] By setting up the cleaning mechanism 7, the inner wall of the water inlet pipe 61 can be cleaned to avoid bacteria and rust generated by 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 to enter the water inlet pipe 61 and move forward along the water inlet pipe 61. When the rotating motor 75 drives the mounting block 76 to rotate, the cleaning brush 73 can be rotated for cleaning, and the cleaning blocks 77 in the annular array can be rotated to achieve scrubbing of the inner wall of the water inlet pipe 61, which is also convenient for flushing stubborn dirt on the inner wall of the front pipe during pulse flushing.

[0061] Working principle: In a specific embodiment of the present invention, the water quality is monitored by the front water quality monitoring module 13. When the water quality reaches the standard of domestic water, it is used normally. When the water quality is abnormal, the water control center 9 is activated to purify the water quality. That is, municipal water enters the water inlet pipe 61 through the municipal water pipe 2, and then the impurities are intercepted by the filter 62. At the same time, the spherical filter 63 can prevent impurities from adhering to the surface of the filter 62 to form a blockage, so that the impurities intercepted by it fall into the collection pipe 64. Then, the municipal water after preliminary filtration passes through the self-cleaning filter 5. Filtering is performed, and the booster pump 3 actively determines the changes in system pressure and flow, and actively increases the water supply pressure. Then, the municipal water processed by the water control center 9 is distributed to various water outlets by the cold water divider 93 and flows into the hot water source 91 for heating, and then distributed to various water outlets by the hot water diverter 92 for use. The thermostatic pipe 94 at the end water outlet of the hot water diverter 92 converges the hot water to the thermostatic concentrator 95, and then the water is sent back to the hot water source 91 through the controller and the circulation pump 4 in the water control center 9, thus ensuring that the end is always open and hot water is available; To ensure the stability of the constant temperature hot water pipe system, it is necessary to regularly pulse clean the internal pipes of the system to ensure that the pipes do not produce scale, and at the same time filter out impurities in the municipal pipe network and automatically discharge sewage. Therefore, when the system is cleaned, the water outlet of the self-cleaning filter 5 is first closed, and its own sewage pipe is opened, and then the self-cleaning filter 5 reversely flushes the filter screen 62 through a pulse jet of high-pressure water; While the filter screen 62 is flushed in reverse, the crushing motor 65 controls the crushing shaft 66 to rotate, so that the multiple groups of crushing blades 67 rotate to crush the collected impurities, and then the pulse water flow flushes the crushed impurities, so that they pass through the slag discharge pipe 68 to achieve slag discharge processing; At the same time, the ball valve 71 is controlled to open, and the driving motor 81 controls the adjusting screw 82 to rotate, so that the movable rod 74 moves linearly on the outer surface of the adjusting screw 82, thereby realizing the advancement of the cleaning block 77 and the cleaning brush 73. When the cleaning block 77 is advanced, another set of buffer telescopic rods 78 is adaptively extended and retracted in the movable tube 72 and the water inlet pipe 61, thereby adjusting the height of the guide wheel 84, so that it rolls on the inner wall of the movable tube 72 and the water inlet pipe 61 to complete the function of guiding support; When the cleaning block 77 is pushed forward, the rotating motor 75 drives the mounting block 76 to rotate, so that the cleaning brush 73 can be rotated and cleaned, and the cleaning block 77 of the annular array can be rotated, so as to scrub the inner wall of the water inlet pipe 61 and wash the surface of the filter screen 62 and the spherical filter screen 63. When the cleaning block 77 rotates, the buffer telescopic rod 78 is used to buffer and reduce the vibration of the cleaning block 77, and the supporting rod 79 is used to auxiliary support the rotating cleaning block 77, so that the cleaning block 77 adapts to the rotation speed of the rotating motor 75; The cleaned impurities are discharged out of the system along with the pulse flushing, thus ensuring the filtering effect of municipal water.
