Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a valve-controlled water meter structure. Background Technology

[0002] In the field of water metering for both residential and industrial use, valve-controlled water meters are the core equipment for achieving water volume statistics and remote management. Their metering accuracy and operational stability are directly related to the balance of interests between water suppliers and water users.

[0003] Traditional valve-controlled water meters are designed primarily for metering accuracy and ease of installation, with insufficient emphasis on tamper protection. Some meters rely solely on simple bolts to secure the tank cover or base meter, lacking effective monitoring and protection mechanisms for abnormal disassembly. In real-world applications, this design is easily exploited by unauthorized users. For example, by prying open the tank cover, disassembling the base meter, or damaging the sealing structure, users can bypass the meter's metering function to steal water, or tamper with core components such as the pulse board and control board to interfere with metering data, leading to significant water loss and economic damage for the water supplier.

[0004] Therefore, it is necessary to provide a valve-controlled water meter structure to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a valve-controlled water meter structure, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a valve-controlled water meter structure, including: a tank body, a tank cover hinged to the top of the tank body, and a magnetic block fixedly connected to the bottom of the tank cover; A control board is fixedly installed inside the compartment. The control board is equipped with a magnetic switch, which is located below the magnetic block. The interior of the compartment is also fixedly connected to a magnetic compartment, and a magnet is slidably connected inside the magnetic compartment. The magnetic compartment is located below the magnetic control switch, and the magnetic poles of the magnet and the magnetic block are opposite on the side that are close to each other. When the magnetic block is close to the magnet, it creates a magnetic field that keeps the magnetic switch closed. When the magnetic block moves away from the magnet, the magnetic field is disrupted, causing the magnetic switch to open.

[0007] Preferably, the bin cover is made of polycarbonate material, the surface of the bin cover has a viewing window, and a display screen is fixedly installed inside the bin body directly below the viewing window. The display screen is electrically connected to the control board, and a connecting pipe is fixedly connected to the bottom of the bin body. The connecting pipe is used to fix the bin body to an external pipeline.

[0008] Preferably, a base surface is also provided inside the tank body. The base surface is located on one side of the inner cavity of the tank body, and a sealing structure is provided between the base surface and the inner wall of the tank body. The sealing structure is made by a potting process to prevent water from seeping into the tank body and contacting the control panel.

[0009] Preferably, the base plate has an impeller cavity, an impeller is rotatably mounted inside the impeller cavity, a small magnet is embedded on the surface of the impeller, and a pulse plate is fixedly installed inside the chamber corresponding to the position of the impeller cavity. A Hall element is set on the pulse plate, the Hall element is located directly above the rotation trajectory of the small magnet, and the Hall element is electrically connected to the control board.

[0010] Preferably, a battery compartment is also fixedly installed inside the compartment, and a replaceable battery is placed inside the battery compartment. The battery compartment is electrically connected to the control board, magnetic switch, pulse board, and display screen.

[0011] Preferably, a valve-controlled motor is also fixedly installed inside the chamber, and a valve plate is fixedly connected to the drive end of the valve-controlled motor. The valve plate is located inside the connecting pipe, and the valve-controlled motor is electrically connected to the control board.

[0012] Preferably, the magnetic chamber is a cylindrical cavity structure with an open top, the inner wall of the magnetic chamber is provided with a smooth coating, and the magnet is a cylindrical permanent magnet adapted to the inner wall of the magnetic chamber, which can slide up and down along the inner wall of the magnetic chamber.

[0013] Compared with related technologies, the valve-controlled water meter structure provided by this utility model has the following beneficial effects: Through the linkage structure of the magnetic block on the tank cover, the magnetic tank magnet, and the magnetic control switch, when the tank cover is closed, the magnetic block and magnet form a stable magnetic field, enabling the magnetic control switch to continuously send normal signals. Once there is any illegal disassembly behavior such as prying open the tank cover or disassembling the base meter, the magnetic field matching state is instantly disrupted. The magnetic control switch can sense the change in real time and transmit an abnormal signal to the control board, realizing an upgrade from passive protection to active monitoring. This prevents illegal water theft or meter tampering from the source and avoids water loss for the water supplier. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1 to 5 A valve-controlled water meter structure includes: a chamber 10, a chamber cover 11, a base meter 20, a control board 30, a magnetic switch 301, a pulse plate 40, and a valve-controlled motor 51. The chamber 10 can be fixedly installed on a pipeline. The chamber cover 11 is located on top of the chamber 10. The base meter 20 is located inside the chamber 10 and can detect the water flow in the pipeline. The control board 30 is also fixedly connected inside the chamber 10 and can control the operation of the valve-controlled water meter. The magnetic switch 301 is installed on the control board 30, and the pulse plate 40 is electrically connected to one side of the control board 30. The valve-controlled motor 51 is also fixedly installed inside the chamber 10 and can block the flow of water in the pipeline.

[0018] The cover 11 is hinged to the top of the body 10 and the two can be fixedly connected by bolts. The cover 11 is made of polycarbonate and has a magnetic block at the bottom. The bottom of the body 10 is fixedly connected to a connecting pipe 12. The body 10 is fixedly installed on the pipe through the connecting pipe 12 to prevent the cover 11 from being opened without authorization. The cover 11 also has a viewing window 111.

[0019] The base meter 20 is located on one side of the inner cavity of the tank body 10. A sealing structure 21 is provided between the base meter 20 and the inner wall of the tank body 10 to prevent water from leaking into the control board 30 and causing circuit damage. The sealing structure 21 can be made using processes such as potting.

[0020] The control board 30 is also electrically connected to a display screen 302, which is fixedly installed inside the tank 10 and located below the viewing window 111. The display screen 302 displays the cumulative water consumption in the current water cycle. The viewing window 111 can serve as a transparent observation channel, allowing users to read the cumulative water consumption directly through the display screen 302 without disassembling the water meter. The magnetic switch 301 is located directly below the magnetic block. The control board 30 also has a communication function, which facilitates remote data interaction.

[0021] A magnetic chamber 31 is fixedly connected inside the chamber 10. A magnet 311 is slidably connected inside the magnetic chamber 31. The magnetic chamber 31 is located directly below the magnetic control switch 301, and the magnetic poles of the magnet 311 and the magnetic block are opposite on the side that are close to each other. After the chamber cover 11 is closed, the magnetic block and the corresponding position on the top of the chamber 10 form a stable magnetic attraction. The magnet 311 is located at the top of the magnetic chamber 31, and its magnetic field covers the magnetic control switch 301, keeping the magnetic control switch 301 in a closed state and continuously sending normal equipment signals to the control board 30. When someone attempts to disassemble the water meter (such as opening the cover 11, prying the tank body 10, or removing the base meter 20), the magnet 311 falls into the bottom of the magnetic tank 31 due to the movement of the magnetic block. This disrupts the magnetic field matching state. The magnetic switch 301 senses the change in the magnetic field and sends an abnormal signal to the control board 30. After receiving the signal, the control board 30 triggers the anti-tamper protection (such as the valve-controlled motor 51 closing the pipe, cutting off the water supply, recording the disassembly log, and subsequently uploading it to the maintenance system for easy traceability).

[0022] The pulse plate 40 is fixedly installed inside the chamber 10. A Hall element is installed inside the pulse plate 40. The impeller cavity 41 is set on the base meter 20. An impeller is rotatably assembled inside the impeller cavity 41. A small magnet is embedded in the impeller. The Hall element on the pulse plate 40 is fixed above the rotation trajectory of the magnet (without physical contact). When the impeller rotates, the magnet passes through the Hall element once, generating a pulse. The control board 30 calculates the real-time flow rate and flow of the water meter according to the pulse constant and the formula, and then displays it on the display screen 302.

[0023] The battery compartment 50 can hold batteries to provide power to the valve-controlled water meter.

[0024] The drive end of the valve-controlled motor 51 is fixedly connected to the valve plate 511, and the valve plate 511 is located inside the pipe. When the control board 30 receives an electrical signal indicating that the magnetic field has been damaged or when the user is in arrears with water fees, it can control the valve plate 511 to close the connecting pipe 12, thereby blocking illegal water use and protecting the accuracy and effectiveness of the water meter's metering function.

[0025] The working principle of the valve-controlled water meter structure provided by this utility model is as follows: When water flows in the pipe, the water flow impacts the impeller in the impeller cavity 41, causing it to rotate. The impeller speed is positively correlated with the water flow speed (the faster the water flow, the faster the impeller rotates). A small magnet is embedded in the impeller. At the same time, a pulse plate 40 with a Hall element is fixedly installed on the outside of the impeller cavity 41. The Hall element is located above the rotation trajectory of the magnet. When the impeller drives the magnet to rotate, the magnet triggers the Hall element to generate an electrical pulse signal every time it passes the Hall element. This signal is then transmitted to the control board 30. The control board 30 has a preset pulse constant (i.e., the number of pulses generated for one cubic meter of water). It performs real-time calculations using a formula to obtain the current water flow speed and cumulative water consumption. The cumulative water consumption is then transmitted to the display screen 302. Users can directly read the data through the viewing window 111 of the cover 11 without disassembling the water meter. A magnetic block is provided at the bottom of the compartment cover 11. A magnetic compartment 31 is fixed inside the compartment body 10, and a magnet 311 is slidably mounted inside the magnetic compartment 31. The magnetic poles of the magnetic block and the magnet 311 are opposite on the side closest to each other. At the same time, the magnetic control switch 301 is fixed on the control board 30, located directly above the magnetic compartment 31. When the compartment cover 11 is closed and fixed with bolts, the magnetic block and the magnet 311 form a stable magnetic attraction, and its magnetic field covers the magnetic control switch 301, keeping the magnetic control switch 301 in a closed state and continuously sending a normal electrical signal to the control board 30. When someone attempts to disassemble the device without authorization, the magnetic control switch will be closed. (For example, opening the cover 11 or prying the body 10 causes the magnetic block to be too far from the magnet 311), the original magnetic field matching state is disrupted. The magnetic control switch 301 senses the change in the magnetic field and immediately sends an electrical signal of equipment abnormality to the control board 30. After receiving the abnormal signal, the control board 30 triggers two operations simultaneously: first, it controls the valve control motor 51 to drive the valve plate 511 to close, cut off the water supply to the pipeline, and prevent unauthorized water use; second, it automatically records the disassembly log, which is subsequently uploaded to the operation and maintenance system through the communication function of the control board 30, so that staff can trace the violation. There are two main types of signals that trigger valve control actions: one is an anti-tampering abnormal signal (the water meter has been illegally dismantled), and the other is an overdue payment signal transmitted by the remote operation and maintenance system (the user has not paid the water fee on time). The drive end of the valve control motor 51 is fixedly connected to the valve plate 511, and the valve plate 511 is located inside the pipe (connected to the connecting pipe 12 at the bottom of the tank 10). When the control board 30 receives the above trigger signal, it immediately sends a closing command to the valve control motor 51. The valve control motor 51 drives the valve plate 511 to rotate to the closed position, blocking the water flow in the connecting pipe 12. After the abnormality is resolved (such as reclosing the tank cover 11 or paying the water fee), the control board 30 sends an opening command, and the valve control motor 51 drives the valve plate 511 to rotate to the open position, restoring the water supply. The internal compartment 10 is equipped with a battery compartment 50, which provides continuous power to all electrical control components such as the control board 30, pulse board 40, valve-controlled motor 51, and display screen 302, ensuring stable operation of the equipment.
