Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to an Internet of Things (IoT) water meter that is tamper-proof. Background Technology

[0002] The Internet of Things (IoT) water meter is a new type of water meter that uses modern microelectronics, modern sensing technology, and smart IC card technology to measure and transmit water usage data and settle transactions for residents every day. Compared with traditional water meters, which generally only have the functions of flow collection and mechanical pointer display of water usage, IoT water meters have made great progress. In addition to recording and electronically displaying water usage, IoT water meters can also control water usage according to agreements, automatically calculate water fees for tiered water pricing, and store water usage data. Currently, IoT water meters generally realize water metering and water usage data upload through a main control module, a metering module, and an NBIOT module.

[0003] In existing technology, water meters have a filter screen installed inside to further filter the incoming water. After prolonged use, a large amount of impurities accumulate on the surface of the filter screen. However, since the filter screen is installed inside the water pipe, workers cannot clean it, leading to a large accumulation of impurities inside the water pipe. This can easily damage the water meter after long-term use, thus reducing the device's practicality. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides an IoT water meter designed to prevent unauthorized tampering.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-tampering IoT water meter, comprising a water pipe body, an inlet pipe at one end of the water pipe body, an outlet pipe at the end of the water pipe body away from the inlet pipe, the inlet pipe of the water pipe body being connected to a pipe via an anti-tampering nut, a water meter body at the upper end of the water pipe body, the water meter body comprising a housing mounted on the water pipe body, a communication component mounted inside the housing, a water flow detection component mounted inside the water pipe body, and a display screen mounted on the housing, and a filter device for filtering impurities in the water mounted on the water pipe body.

[0006] By adopting the above technical solution, when the device is in use, the staff installs it into the pipeline through the inlet and outlet pipes, allowing water to flow in through the inlet pipe and out through the outlet pipe. During this process, the water flow detection device inside the main body of the water pipe monitors the water flow, calculates the water consumption, transmits the data to the cloud through the communication component, and displays the water consumption on the screen. In this process, the filtration device filters impurities in the water flow, and the filtration device is easy to clean, thereby reducing the probability of a large amount of impurities accumulating inside the water meter, thus improving the practicality of the device.

[0007] Furthermore, the filtration device includes a connecting pipe installed at the end of the water pipe body away from the inlet pipe, a filter pipe installed below the connecting pipe, and a filter element installed inside the filter pipe, wherein the upper end of the filter element abuts against the inner top wall of the connecting pipe.

[0008] Furthermore, a sealing element is threaded to the end of the filter tube away from the connecting tube, and the lower end of the filter element abuts against the sealing element.

[0009] By adopting the above technical solution, after water flows in through the inlet pipe and out through the outlet pipe, the water flows into the connecting pipe, which then allows the filter element to filter impurities in the water flow. The filtered impurities fall into the filter tube, which then collects the filtered impurities. When the staff needs to clean the impurities, they need to open the filter tube by rotating the seal, allowing the impurities to be discharged through the filter tube. During this process, the staff can also remove the filter element for cleaning, thereby reducing the probability of a large amount of impurities accumulating inside the water meter and improving the practicality of the device.

[0010] Furthermore, a retaining spring is fixedly provided on the sealing element, and an abutting plate is fixedly provided on the other end of the retaining spring. The side wall of the abutting plate away from the retaining spring abuts against the filter element.

[0011] By adopting the above technical solution, when the staff installs the filter element into the filter tube, the filter element presses against the inner wall of the connecting tube under the action of the clamping spring and the abutment plate, thereby reducing the probability of gaps between the filter element and the filter tube and improving the filtration effect.

[0012] Furthermore, a limiting rod is fixedly provided on the sealing element, and a limiting hole is opened on the side wall of the abutment plate near the clamping spring. The limiting rod is slidably connected to the limiting hole.

[0013] By adopting the above technical solution, when the abutment plate moves under the action of the clamping spring, the limiting rod limits the abutment plate, thereby reducing the probability of shaking during the movement of the abutment plate and improving the stability of the device.

[0014] Furthermore, a sealing cylinder is fixedly provided on the sealing element, and the abutment plate is slidably connected to the sealing cylinder.

[0015] Furthermore, an installation groove is provided on the outer wall of the abutment plate, and a sliding sealing ring is installed in the installation groove.

[0016] By adopting the above technical solution, the sealing cylinder and sliding sealing ring reduce the probability of water seeping into the sealing cylinder, thereby reducing the probability of corrosion of the clamping spring and extending the service life of the clamping spring.

[0017] Furthermore, the outer casing is provided with a protective cover for protecting the display screen.

[0018] By adopting the above technical solution, the outer casing reduces the probability of the display screen being damaged, thereby extending the service life of the water meter body.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when the device is in use, the staff installs the device into the pipeline through the inlet pipe and the outlet pipe, so that water flows in through the inlet pipe and out through the outlet pipe. During this process, the water flow detection device in the main body of the water pipe monitors the water flow and calculates the water consumption. The data is transmitted to the cloud through the communication component and the water consumption is displayed on the screen at the same time. During this process, the filtration device filters the impurities in the water flow. The filtration device is easy to clean, thereby reducing the probability of a large amount of impurities accumulating inside the water meter, thus improving the practicality of the device.

[0021] 2. In this application, after water flows in through the inlet pipe and out through the outlet pipe, the water flows into the connecting pipe, which in turn allows the filter element to filter impurities in the water flow. The filtered impurities fall into the filter tube, which then collects the filtered impurities. When the staff needs to clean the impurities, they need to open the filter tube by rotating the seal, allowing the impurities to be discharged through the filter tube. During this process, the staff can also remove the filter element for cleaning, thereby reducing the probability of a large amount of impurities accumulating inside the water meter and improving the practicality of the device.

[0022] 3. In this application, when the staff installs the filter element into the filter tube, the filter element presses against the inner wall of the connecting tube under the action of the clamping spring and the abutment plate, thereby reducing the probability of gaps between the filter element and the filter tube and improving the filtration effect.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-3 As shown in the figure, this application discloses an anti-tampering IoT water meter, including a water pipe body 1, an inlet pipe 11, an outlet pipe 12, a water meter body 2, a filter device 3, a sealing element 4, a clamping spring 5, a contact plate 51, a limiting rod 6, a sealing cylinder 7, and a sliding sealing ring 81. The inlet pipe 11 is a cylindrical structure and is located at one end of the water pipe body 1. The outlet pipe 12 is a cylindrical structure and is located at the end of the water pipe body 1 away from the inlet pipe 11. The inlet pipe 11 of the water pipe body 1 is connected to the pipe by an anti-tampering nut (not shown in the figure), which is used to prevent water theft. The water meter body 2 is located at the upper end of the water pipe body 1 and includes a shell 21, a communication component, a water flow detection component, and a display screen 22. The shell 21 is located on the water pipe body 1, and the communication component (not shown in the figure) is located inside the shell 21 for transmitting signals. The water flow detection component (not shown in the figure) is located inside the water pipe body 1 for monitoring water consumption. The display screen 22 is mounted on the housing 21 and is used to display the water consumption.

[0029] When the device is in use, the operator installs it into the pipeline through the inlet pipe 11 and the outlet pipe 12, allowing water to flow in through the inlet pipe 11 and out through the outlet pipe 12. During this process, the water flow detection device inside the main body of the water pipe 1 monitors the water flow and calculates the water consumption. The data is transmitted to the cloud through the communication component and the water consumption is displayed on the display screen 22. In this process, the filter device 3 filters impurities in the water flow. The filter device 3 is easy to clean, which reduces the probability of a large amount of impurities accumulating inside the water meter, thereby improving the practicality of the device.

[0030] A filter device 3 is installed on the water pipe body 1 to filter impurities in the water. The filter device 3 includes a connecting pipe 31, a filter pipe 32, and a filter element 33. The connecting pipe 31 is a cylindrical structure and is installed at the end of the water pipe body 1 away from the inlet pipe 11. The filter pipe 32 is a cylindrical structure and is installed below the connecting pipe 31. The filter element 33 is installed inside the filter pipe 32, and the upper end of the filter element 33 abuts against the inner top wall of the connecting pipe 31.

[0031] The sealing element 4 is threadedly connected to the end of the filter tube 32 away from the connecting tube 31, and the lower end of the filter element 33 abuts against the sealing element 4.

[0032] After water flows in through the inlet pipe 11 and out through the outlet pipe 12, it flows into the connecting pipe 31, which in turn causes the filter element 33 to filter impurities in the water flow. The filtered impurities fall into the filter pipe 32, where they are collected. When the staff needs to clean the impurities, they need to open the filter pipe 32 by rotating the sealing element 4, allowing the impurities to be discharged through the filter pipe 32. During this process, the staff can also remove the filter element 33 for cleaning, thereby reducing the probability of a large amount of impurities accumulating inside the water meter and improving the practicality of the device.

[0033] The clamping spring 5 is fixedly mounted on the sealing element 4, and the abutting plate 51 is fixedly mounted on the other end of the clamping spring 5. The side wall of the abutting plate 51 away from the clamping spring 5 abuts against the filter element 33.

[0034] When the staff installs the filter element 33 into the filter tube 32, the filter element 33 presses against the inner wall of the connecting tube 31 under the action of the clamping spring 5 and the abutment plate 51, thereby reducing the probability of gaps between the filter element 33 and the filter tube 32 and improving the filtration effect.

[0035] A limiting hole 61 is provided on the side wall of the abutment plate 51 near the clamping spring 5. The limiting rod 6 is a round rod structure with its axis vertical. The limiting rod 6 is fixedly set on the sealing member 4 and is slidably connected to the limiting hole 61.

[0036] When the abutment plate 51 moves under the action of the clamping spring 5, the limiting rod 6 limits the abutment plate 51, thereby reducing the probability of the abutment plate 51 shaking during movement and thus improving the stability of the device.

[0037] The sealing cylinder 7 is fixedly mounted on the sealing element 4, and the abutment plate 51 is slidably connected to the sealing cylinder 7. An installation groove 8 is provided on the outer wall of the abutment plate 51, and the sliding sealing ring 81 is installed in the installation groove 8.

[0038] The sealing cylinder 7 and the sliding sealing ring 81 reduce the probability of water seeping into the sealing cylinder 7, thereby reducing the probability of corrosion of the clamping spring 5 and extending the service life of the clamping spring 5.

[0039] To extend the service life of the water meter body 2, a protective shell is provided on the outer casing 21 to protect the display screen 22. The outer casing 21 reduces the probability of the display screen 22 being damaged, thereby extending the service life of the water meter body 2.

[0040] The working principle of the anti-tampering IoT water meter in this embodiment is as follows: When the device is in use, the staff installs the device into the pipeline through the inlet pipe 11 and the outlet pipe 12, so that water flows in through the inlet pipe 11 and out through the outlet pipe 12. During this process, the water flow detection device in the main body of the water pipe 1 monitors the water flow and calculates the water consumption. The data is transmitted to the cloud through the communication component and the water consumption is displayed on the display screen 22. During this process, the filter device 3 filters the impurities in the water flow. The filter device 3 is easy to clean, thereby reducing the probability of a large amount of impurities accumulating inside the water meter, thus improving the practicality of the device.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
