Description

Dual-circulation smart water meter Technical Field

[0001] This invention relates to the field of smart water meter technology, and in particular to a dual-circuit smart water meter. Background Technology

[0002] A water meter is an instrument that measures the flow of water. Most of them measure the cumulative flow of water. In order to save water resources and control human waste of water resources, water meters are usually installed on the water inlet pipe of each household. In this way, the flow of water passing through the tap can be measured by the water meter.

[0003] With the continuous improvement of living standards, direct drinking water is widely used in households. Direct drinking water equipment produces drinking water that is delivered to homes through a direct drinking water pipeline network. To ensure the quality of the output drinking water, bacteria can grow in the water if it remains unused for a long time. Therefore, it is necessary to treat the unused drinking water through a direct drinking water circulation system. To avoid incorrect billing during direct drinking water circulation, Chinese Patent Publication No. CN217580388U discloses a direct drinking water circulation meter and circulation pipeline network. This system uses two metering components to separately measure the flow paths of the outgoing and return water, thus preventing water charges from being incurred during the direct drinking water circulation process. Technical issues

[0004] However, the need for two metering components to measure water usage makes the internal water circuit structure of the metering unit quite complex, and assembling the metering components is also cumbersome. Therefore, designing a technology that facilitates component assembly is the technical problem this invention aims to solve. Technical solutions

[0005] The technical problem to be solved by the present invention is to provide a dual-circuit smart water meter that facilitates the assembly of components of the dual-circuit smart water meter.

[0006] The technical solution provided by this invention is a dual-circuit smart water meter, comprising:

[0007] The water meter body is provided with an inlet pipe and a return pipe. The inlet pipe has an inlet and an outlet at both ends, and the return pipe has an inlet and an outlet at both ends. The water meter body is also provided with two first mounting holes.

[0008] A water inlet meter core, wherein the water inlet meter core is disposed in one of the first mounting holes;

[0009] A return water meter core is disposed in another of the first mounting holes;

[0010] A pressure transmitter, wherein the pressure transmitter is installed on the water inlet pipe;

[0011] A controllable inlet valve is provided on the inlet pipe;

[0012] A controllable return water valve is installed on the return water pipe;

[0013] The main controller is configured to receive and process electrical signals from the pressure transmitter, the inlet control valve, and the return control valve. Beneficial effects

[0014] Compared with existing technologies, the advantages and positive effects of this invention are as follows: By setting inlet and return water pipes on the water meter body, the requirements for circulating drinking water that has not been used for a long time are met. Correspondingly, a first mounting hole is provided on the water meter body to facilitate the installation of the inlet and return water meter cores, thus enabling convenient assembly of components for a dual-circuit smart water meter. Through the cooperation of the inlet controllable valve and the return controllable valve, the requirements for normal drinking water output can be met, and the circulating treatment of drinking water that has not been used for a long time can be controlled by opening the return controllable valve.

[0029] As shown in Figures 1-12, the present invention provides a dual-circuit smart water meter. The water meter body 1 includes an inlet pipe 2 and a return pipe 3 respectively disposed on the water meter body 1. The two ends of the inlet pipe 2 are respectively provided with an inlet pipe inlet 201 and an inlet pipe outlet 202. The two ends of the return pipe 3 are respectively provided with a return pipe inlet 301 and a return pipe outlet 302. The inlet pipe inlet 201 and the return pipe outlet 302 are located at the same end of the water meter body 1, and the inlet pipe outlet 202 and the return pipe inlet 301 are located at the other end of the water meter body 1. A first water flow path is formed between the inlet pipe inlet 201, the water meter body 1 and the inlet pipe outlet 202, and a second water flow path is formed between the return pipe inlet 301, the water meter body 1 and the return pipe outlet 302. The water meter body 1 forms a dual-circuit system with the cooperation of the first water flow path and the second water flow path.

[0030] The inlet pipe 2 and the return pipe 3 are connected to a tee pipe 106 at the user end. The other end of the tee pipe 106 is connected to the faucet 107 in the user's home. The inlet pipe 2 and the return pipe 3 can also be directly connected to the circulating faucet 107 with inlet and return water interfaces. Two meter cores are set in the water meter body 1. The two meter cores are the inlet meter core 4 set in the inlet pipe 2 and the return meter core 5 set in the return pipe 3.

[0031] A pressure transmitter 9 is also installed inside the water meter body 1, and the pressure transmitter 9 is installed on the water inlet pipe 2.

[0032] It should be noted here that by using the inlet pipe 2 and the return pipe 3 to form a dual circulation, the water in the pipe from the water meter body 1 to the faucet can be circulated, thereby avoiding the formation of stagnant water that breeds bacteria and affects the health of users.

[0033] The water meter body 1 is provided with two meter cores, namely the inlet meter core 4 set in the first water flow path and the return meter core 5 set in the second water flow path. The water meter body 1 is provided with an installation component for installing the inlet meter core 4 and the return meter core 5, and a sealing component for sealing the inlet meter core 4 and the return meter core 5 during the installation process.

[0034] It should be noted that by setting two meter cores within the water meter body 1, a dual metering unit and dual-pipeline differential metering are formed. Metering only begins when the user's actual water usage results in a difference; circulating water is not metered or billed. This not only meets the need for accurate metering but also addresses the requirement for flowing water in direct drinking water systems, meeting drinking water hygiene requirements. Furthermore, it enables real-time, fixed-point monitoring and management of user water consumption and circulating water volume, allowing for tiered pricing and prepayment. The intelligent control system collects various parameters of the water meter into the system, enabling dynamic monitoring of user water usage, calculation of water fees, and timely detection of abnormal water usage through data analysis.

[0035] Please refer to Figure 4. The water meter body 1 shown in the figure is equipped with two controllable valves. The two controllable valves are the inlet controllable valve 7 installed in the inlet pipe 2 and the return controllable valve 8 installed in the return pipe 3. The water meter body 1 is equipped with a main controller for receiving and processing the electrical signals of the pressure transmitter 9, the inlet controllable valve 7 and the return controllable valve 8. The water meter body 1 is equipped with a battery 10 for supplying power to the pressure transmitter 9, the inlet controllable valve 7, the return controllable valve 8 and the main controller. The battery 10 is detachably connected to the water meter body 1.

[0036] It should be noted that when a user experiences a pipe leak or intentional water theft, the pressure inside the pipe is slowly released. When the pressure drops to a preset threshold, the pressure transmitter 9 sends a signal to the main controller. For example, if the pipe pressure is normally greater than 0.1 MPa and starts dripping, and the pressure drops below 0.03 MPa, the inlet controllable valve 7 is opened, filling the pipe with water. After the pressure rises to 0.03 MPa, there is a 5-second delay. If no new water flow is detected within 5 seconds, the inlet controllable valve 7 is closed. If water flows through, the timer restarts after 5 seconds once the flow stops. After three consecutive checks, if the pressure inside the pipe slowly decreases each time, it can be determined that there is a pipe leak or intentional water theft by the user. At this point, an alarm message is sent and the inlet controllable valve 7 is closed, thus forming a leak alarm valve shut-off, which can prevent accidental pipe leaks or intentional water theft by the user.

[0037] It is worth noting that when a user is using water, drinking water enters through the inlet pipe 2. When the faucet is turned on, the pressure inside the pipe drops instantly, and the main controller opens the inlet control valve 7, allowing the user to use water normally. However, if the user does not use water for an extended period, exceeding the set time, a water return operation is required. During the water return operation, both the water return control valve 8 and the inlet control valve 7 open, allowing drinking water to enter the inlet pipe 2 through the inlet pipe inlet 201 and then flow into the water meter body 1. The water flows through the inlet controllable valve 7, the inlet meter core 4, and then from the inlet pipe outlet 202 of the inlet pipe 2 to the tee pipe. It then enters the return pipe 3 from the return pipe inlet 301, flows into the water meter body 1, passes through the return meter core 5 and the return controllable valve 8, and then flows out from the return pipe outlet 302 of the return pipe 3 to the direct drinking water network and back to the water storage tank. When measuring the actual water consumption of the user, the value of the inlet meter core 4 minus the value of the return meter core 5 is the actual water consumption of the user.

[0038] It is important to emphasize that when the faucet in a user's home is not turned on, the inlet controllable valve 7 is closed. When the faucet is turned on, the pressure in the pipe drops instantly, and the main controller controls the inlet controllable valve 7 to open. During normal water use, the inlet controllable valve 7 and the return controllable valve 8 are electrically connected to the main controller. The pressure transmitter 9 can also be installed on the external pipe connected to the inlet pipe 2. For pressure transmitter 9 installed outside the inlet pipe, it can be placed between the control valve and the faucet. During normal water use, the return controllable valve 8 is closed. When the user does not use water for a long time, exceeding the set time, the main controller controls the return controllable valve 8 and the inlet controllable valve 7 to open, thus forming a passage between the inlet pipe 2, the return pipe 3, and the tee pipe. Under the pressure of the drinking water supply network, the water in the inlet pipe 2 and the return pipe 3 flows into the second water flow path of the drinking water network, thus realizing the return water. The return water meter core 5 and the inlet water meter core 4 count simultaneously, and the main controller can know the amount of return water and deduct it to avoid overcharging the user.

[0039] Please refer to Figures 5-11. The installation components shown include multiple installation tubes 1201 fixedly connected to the first installation hole 11. Each installation tube 1201 is connected to a circular plate 1202 via a guide component. Each circular plate 1202 is connected to an installation plate 1203 via multiple telescopic components. Each installation plate 1203 has a bevel 1204 on the side near the installation cover 601. Each installation tube 1201 has multiple through holes 1205 on its sidewall. Each installation tube 1201 is provided with a drive component for driving the circular plate 1202. The sidewalls of the inlet water meter core 4 and the return water meter core 5 are fixedly connected to installation rings 1206. The two installation rings 1206 are fixedly connected to multiple ear plates 1207. Each ear plate 1207 has a fixing hole that matches the installation tube 1201. The inner walls of the two first installation holes 11 have multiple countersunk holes 1208. Each ear plate 1207 is slidably connected to the countersunk hole 1208.

[0040] It should be noted here that: through the configuration of the installation components, the coordinated action of the telescopic components, guide components, and drive components enables the synchronous locking and fixation of multiple mounting points of the watch movement. This improves the efficiency of watch movement installation while ensuring that the force on each mounting point is uniform during the installation process, thereby reducing the risk of watch movement deformation and damage.

[0041] Please refer to Figure 9. The telescopic assembly shown in the figure includes a telescopic hole 1301 opened on the side wall of the circular plate 1202, a mounting plate 1203 slidably connected to the telescopic hole 1301, a first spring 1302 fixedly connected to the bottom wall of the telescopic hole 1301, and the other end of the first spring 1302 connected to the mounting plate 1203.

[0042] It should be noted here that the telescopic component is used to guide and reset the mounting plate 1203.

[0043] Please refer to Figure 9. The guide assembly shown in the figure includes two guide holes 1401 opened on the side wall of the mounting tube 1201. Guide plates 1402 are slidably connected to the two guide holes 1401. One end of the two guide plates 1402 is connected to the circular plate 1202.

[0044] It should be noted here that the guide component is used to guide and limit the movement of the circular plate 1202.

[0045] Please refer to Figures 8 and 9. The drive assembly shown includes a threaded rod 1501 rotatably connected to each mounting tube 1201, a circular plate 1202 threadedly connected to the threaded rod 1501, a gear 1502 fixedly connected to the side wall of each threaded rod 1501, a drive ring 1503 rotatably connected to the first mounting hole 11, a plurality of drive teeth 1504 fixedly connected to the side of the drive ring 1503 near the mounting tube 1201, a clearance hole 1505 opened on the side of each mounting tube 1201 near the drive ring 1503, each drive tooth 1504 rotatably connected to the clearance hole 1505 and meshing with the gear 1502, and a hexagonal drive hole opened at the end of each threaded rod 1501 near the mounting cover 601.

[0046] It should be noted that the drive component is designed to facilitate the synchronous rotation of the remaining threaded rods 1501, thereby synchronously moving the mounting plates 1203 inside the different mounting pipes 1201. This achieves synchronous clamping at different positions of the mounting ring 1206, and thus synchronous locking and fixing of multiple mounting points of the water inlet meter core 4.

[0047] Please refer to Figures 10 and 11. The error-proofing component shown includes a sliding rod 1601 slidably connected to two first mounting holes 11. The two sliding rods 1601 are staggered. Multiple error-proofing plates 1602 are fixedly connected to the side walls of the two sliding rods 1601. Two mounting rings 1206 are respectively provided with error-proofing holes 1604 that match each error-proofing plate 1602. Retaining rings 1603 are fixedly connected to the side walls of the two sliding rods 1601.

[0048] It should be noted here that the installation of the anti-misalignment component makes it easy to distinguish the installation positions of the inlet water meter core 4 and the return water meter core 5, thus avoiding misalignment on the two first mounting holes 11.

[0049] Please refer to Figure 11. The sealing assembly shown in the figure includes annular sealing grooves 1701 formed in the inner walls of two first mounting holes 11. Rubber airbags 1702 are provided in the two annular sealing grooves 1701. The two sliding rods 1601 are provided with an air injection assembly for injecting air into the two rubber airbags 1702.

[0050] It should be noted here that the sealing components are used to create a sealed protection for the water inlet meter core 4.

[0051] Please refer to Figure 11. The air injection assembly shown in the figure includes an air injection hole 1801 opened in the first mounting hole 11. The bottom wall of the air injection hole 1801 is connected to the rubber air bag 1702 through an air injection tube. An air injection plate 1802 is slidably connected to the air injection hole 1801. One end of the sliding rod 1601 is connected to the air injection plate 1802. A second spring 1803 is sleeved on the side wall of the sliding rod 1601. The two ends of the second spring 1803 are respectively connected to the air injection plate 1802 and the side wall of the air injection hole 1801.

[0052] It should be noted here that the air injection component is used to inflate the rubber airbag 1702, causing the rubber airbag 1702 to expand under air.

[0053] Working principle: When using this dual-head dual-circulation smart water meter, the inlet water meter core 4 and the return water meter core 5 need to be installed first. When installing the inlet water meter core 4, it is first placed into the first mounting hole 11. During the process of placing it into the first mounting hole 11, the anti-misalignment hole 1604 on the mounting ring 1206 on the side wall of the inlet water meter core 4 needs to match the anti-misalignment plate 1602 in the first mounting hole 11. Through the matching of the anti-misalignment hole 1604 and the anti-misalignment plate 1602, it is easy to distinguish the installation positions of the inlet water meter core 4 and the return water meter core 5, and avoid misalignment in the two first mounting holes 11. Under the anti-misalignment effect of the anti-misalignment hole 1604 and the anti-misalignment plate 1602, during the process of placing the inlet water meter core 4 into the first mounting hole 11, the fixing holes on the multiple ear plates 1207 are matched with the mounting tube 1201.

[0054] After aligning the fixing holes on each ear plate 1207 with the mounting tube 1201, continuously push the water inlet meter core 4 into the first mounting hole 11 until each ear plate 1207 abuts against the bottom wall of the countersunk hole 1208 on the inner wall of the first mounting hole 11. Then, insert an Allen wrench into the drive hole on any threaded rod 1501 and rotate the Allen wrench to drive the threaded rod 1501 to rotate. During the rotation of the threaded rod 1501, under the threaded meshing transmission action between the threaded rod 1501 and the circular plate 1202 and the guiding action of the guide assembly, the circular plate 1202 can be driven to rotate. As the plate 1202 moves closer to the mounting ring 1206, when each mounting plate 1203 on the circular plate 1202 engages with the through hole 1205, the elastic action of the telescopic component will push each mounting plate 1203 out of the mounting tube 1201. As the circular plate 1202 continues to move, when each mounting plate 1203 abuts against the side wall of the mounting ring 1206, the rotation of the threaded rod 1501 can be stopped. Thus, under the abutting action of each mounting plate 1203, the installation and fixation of the water inlet meter core 4 is achieved.

[0055] Furthermore, during the rotation of the threaded rod 1501, it will drive the gear 1502 to rotate synchronously. Then, under the synchronous meshing transmission action of each drive tooth 1504 and the gear 1502, it will drive the other threaded rods 1501 to rotate synchronously, thereby synchronously driving the mounting plates 1203 inside different mounting tubes 1201 to move. This achieves synchronous clamping at different positions of the mounting ring 1206, thereby achieving synchronous locking and fixing of multiple mounting points of the water inlet meter core 4. This improves the installation efficiency of the water inlet meter core 4 while ensuring that the force on each mounting point of the water inlet meter core 4 is uniform during the installation process, thus reducing the risk of deformation and damage to the water inlet meter core 4.

[0056] Furthermore, when the mounting plate 1203 squeezes and pushes the water inlet meter core 4, the air injection plate 1802 at one end of the sliding rod 1601 will slide in the air injection hole 1801 under the action of the pushing force, thereby pushing the gas in the air injection hole 1801 from the air injection tube into the rubber air bag 1702, causing the rubber air bag 1702 to expand with air. The expanded rubber air bag 1702 abuts against the side wall of the water inlet meter core 4, thereby forming a sealed protection for the water inlet meter core 4.

[0057] After the inlet water meter core 4 is installed, the return water meter core 5 is installed in the same way. After the inlet water meter core 4 and the return water meter core 5 are installed, the mounting cover 601 can be installed on the water meter body 1 with screws. This completes the installation of the two meter cores.

[0058] After the dual-meter core is installed, connect the inlet pipe 201 to the drinking water supply network, and connect the outlet pipe 202 to the user's household water supply pipe. Connect the return pipe inlet 301 to the user's return pipe, and connect the return pipe outlet 302 to the second water flow path of the drinking water network. After connecting the water meter body 1, it can be used normally. During the entire use process, the water consumption on the inlet pipe section can be obtained through communication between the main controller and the metering component. When the metering component detects a large water consumption, the return water controllable valve 8 can be kept closed. Because of the large water consumption, there will be no water accumulation problem on the inlet pipe section. At the same time, when the water consumption is low, the return water controllable valve 8 can be automatically controlled to open and close. The water accumulated in the first water flow path is circulated back, effectively avoiding the pollution problem of stagnant water. At the same time, the water meter has two built-in metering units and dual-pipe differential metering. Metering only starts when the user's actual water consumption results in a difference. The circulating water is not metered or billed. This not only meets the need for accurate metering but also solves the need for flowing water for direct drinking water, meeting drinking water hygiene requirements. It also monitors and manages the user's water consumption and circulating water volume in real time and at fixed points, enabling tiered charging and prepayment. Through the intelligent control system, various parameters of the water meter are collected into the system, so as to dynamically grasp the user's water consumption, calculate water fees, and promptly detect abnormal water consumption by analyzing various data.

[0059] During use, the water meter body 1 can measure and count the user's water consumption through the inlet meter core 4. For example, a normal large water bottle has a capacity of 18L, and the protection value is set to 20L. When the continuous water consumption exceeds 20L, it is temporarily determined that the user's house is running water. The inlet controllable valve 7 is closed for the first time. After the valve is closed for m seconds, the alarm is automatically lifted, and the user can still use water. When the continuous water consumption exceeds 20L again, the inlet controllable valve 7 is closed again and an alarm is triggered. This is repeated three times in a row. If this is determined to be running water, the inlet controllable valve 7 is completely closed, and an alarm message is sent to the user's mobile phone. After confirming that the water was released manually or that the water has returned to normal, the closure is lifted. This forms a water run alarm function, which can prevent the risk of water waste caused by pipe damage or the user's tap not being turned off.

[0060] Meanwhile, when a user experiences pipe leakage or intentional water theft, the pressure inside the pipe is slowly released. When the pressure falls below a preset threshold, the pressure transmitter 9 transmits a signal to the main control unit. For example, if the pipe pressure is normally greater than 0.1 MPa and starts dripping, when the pressure drops below 0.03 MPa, the valve is opened to add water, filling the pipe. After the pressure rises to 0.03 MPa, there is a 5-second delay. If no new water flow is detected within 5 seconds, the valve is closed. If water flows, the flow stops for 5 seconds and the timing restarts. After three consecutive checks, if the pressure inside the pipe slowly decreases each time, it can be determined that there is pipe leakage or intentional water theft by the user. At this time, an alarm message is sent and the controllable inlet valve 7 is closed, thus forming a leak alarm valve shut-off, which can prevent accidental pipe leakage or intentional water theft by the user.

[0061] As shown in Figures 13 and 14, in another embodiment of this application, the water meter body 1 is provided with a first connecting hole 203 and a second connecting hole 303. The water inlet pipe 2 is connected to the first mounting hole 11 where the water inlet meter core 4 is installed through the first connecting hole 203, and the water return pipe 3 is connected to the first mounting hole 11 where the water return meter core 5 is installed through the second connecting hole 303.

[0062] Specifically, two relatively independent first mounting holes 11 are provided on the water meter body 1 to meet the installation requirements of the inlet water meter core 4 and the return water meter core 5. The inlet water pipe 2 is connected to the first mounting holes 11 through a corresponding first connecting hole 203 to allow the flow rate of water transported by the inlet water pipe 2 to be detected via the inlet water meter core 4. Similarly, the return water pipe 3 is connected to the corresponding first mounting holes 11 through a corresponding second connecting hole 303 to allow the flow rate of water transported by the return water pipe 3 to be detected via the return water meter core 5. This allows for easier installation of the inlet water meter core 4 and the return water meter core 5 through the first mounting holes 11, thus fulfilling the requirements for water circuit connection.

[0063] Furthermore, since the water meter body 1 also requires the installation of the inlet controllable valve 7, pressure transmitter 9 and return controllable valve 8, and to reduce the processing difficulty of the internal water circuit structure in the water meter body 1, the water meter body 1 includes a first mounting component 101 and a second mounting component 102. The first mounting component 101 is provided with a first mounting hole 11, and the first mounting component 101 is also provided with a first sub-inlet pipe 21 and a first sub-return pipe 31. One of the first mounting holes 11 is connected to the first sub-inlet pipe 21 through the first connecting hole 203, and the other first mounting hole 11 is connected to the first sub-return pipe 31 through the second connecting hole 203.

[0064] The second mounting component 102 is provided with a second sub-inlet pipe 22 and a second sub-return pipe 32. The second mounting component 102 is provided with a second mounting hole 12, a third mounting hole 13 and a fourth mounting hole 14. The second mounting hole 12 and the third mounting hole 13 are respectively connected to the second sub-inlet pipe 22, and the fourth mounting hole 14 is connected to the second sub-return pipe 32.

[0065] The controllable inlet valve 7 is disposed in the second mounting hole 12 and configured to control the opening and closing of the second sub-inlet pipe 22; the pressure transmitter 9 is disposed in the third mounting hole 13 and configured to detect the water pressure in the second sub-inlet pipe 22; and the controllable return valve 8 is disposed in the fourth mounting hole 14 and configured to control the opening and closing of the second sub-return pipe 32.

[0066] The second mounting component 102 is detachably mounted on the first mounting component 101. The first sub-inlet pipe 21 is connected to the second sub-inlet pipe 22 to form the inlet pipe 2. The first sub-return pipe 31 is connected to the second sub-return pipe 32 to form the return pipe 3.

[0067] Specifically, the water meter body 1 adopts a split structure design, which includes a first mounting part 101 and a second mounting part 102. The first mounting part 101 has a first mounting hole 11 to meet the installation requirements of the inlet water meter core 4 and the return water meter core 5. The second mounting part 102 has a second mounting hole 12, a third mounting hole 13 and a fourth mounting hole 14. The three mounting holes on the second mounting part 102 meet the installation requirements of the inlet water controllable valve 7, the pressure transmitter 9 and the return water controllable valve 8, thereby facilitating the assembly of the inlet water controllable valve 7, the pressure transmitter 9 and the return water controllable valve 8 onto the second mounting part and connecting them to the corresponding inlet water pipe 2 and return water pipe 3, thereby improving the convenience of component assembly.

[0068] In addition, since the water meter body 1 adopts a split structure design, the overall length of the first sub-inlet pipe 21 and the first sub-return pipe 31 formed by the first mounting component 101 is relatively short. Similarly, the overall length of the second sub-inlet pipe 22 and the second sub-return pipe 32 set on the second mounting component 102 is relatively short. After the first mounting component 101 and the second mounting component 102 are assembled together, they form parallel water inlet pipe 2 and water return pipe 3, which is more conducive to reducing the processing difficulty of the water meter body 1.
