Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically to an ultrasonic water meter with a leakage alarm function. Background Technology

[0002] With the development of fluid monitoring technology, gas leak detection and alarm devices have been widely used. However, these products still have some problems in practical use. For example, current leak alarm devices on the market usually use traditional gas sensor detection methods, which have a slow response speed and are difficult to achieve accurate detection in complex working conditions. This leads to problems such as low safety and inconvenience in some scenarios.

[0003] To improve performance, some manufacturers have attempted to enhance the accuracy and reliability of detection by adding intelligent detection algorithms. However, such improvements often face challenges such as complex detection equipment, high costs, and difficult maintenance, making it difficult to promote the overall system.

[0004] A search revealed patent document CN115388340B, published on September 3, 2024. This patent discloses a pipeline leak alarm device, including a valve body, a winding seat, a winding coil, a valve core, a return spring, and an alarm. The device achieves leak detection through an electrical circuit design between the winding coil and the alarm. While this structure can detect pipeline leaks to a certain extent, its reliance on the electrical circuit results in a high circuit failure rate and susceptibility to electromagnetic interference in complex environments, affecting detection accuracy. Furthermore, the device's ability to locate the leak source is relatively coarse, failing to accurately pinpoint the leak location and reducing overall safety.

[0005] A search revealed patent document CN115507309B, published on March 14, 2023. This patent discloses a gas leak alarm method and system. It determines the positional relationship of control valves by acquiring a structural diagram of the gas transmission pipeline network, constructing a topological diagram of the control valves, and calculating a loss coefficient based on gas flow information to determine whether a leak exists. While this method can detect leaks relatively accurately, it relies on complex data processing and algorithm analysis, and may suffer from latency issues in scenarios with high real-time requirements. Furthermore, the system requires the installation of detection modules in multiple locations, resulting in high installation and maintenance costs, and it is highly dependent on network communication, making it susceptible to network failures.

[0006] The aforementioned problems indicate that traditional leak alarm devices currently on the market are unable to effectively meet the new requirements for accurate detection and rapid response under complex operating conditions. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0021] like Figure 1-2 As shown, a pair of connecting water pipes 3 are bolted to both sides of the ultrasonic sleeve tube 1. Threaded grooves are formed on the outer sides of the pair of connecting water pipes 3. A pair of threaded sleeve tubes 2 are respectively threadedly fitted onto the inner sides of the threaded grooves. The ultrasonic detection structure is installed inside the ultrasonic sleeve tube 1. The protective connection structure is installed on the pair of threaded sleeve tubes 2 and the ultrasonic sleeve tube 1. The central processing unit is installed inside the ultrasonic sleeve tube 1 and connected to the ultrasonic detection structure. The leakage alarm and the display module are installed on the outer side of the ultrasonic sleeve tube 1. The wireless communication module is inserted into the ultrasonic sleeve tube 1 and electrically connected to the central processing unit. The ultrasonic detection structure includes: a pair of ultrasonic generators 4, a pair of ultrasonic receivers 5, and a pair of signal amplifiers 6.

[0022] Specifically, the inner side of the ultrasonic sleeve tube 1 is provided with two pairs of mounting slots. A pair of ultrasonic generators 4 and a pair of ultrasonic receivers 5 are respectively installed on the inner side of the two pairs of mounting slots, and the pair of ultrasonic receivers 5 are respectively arranged opposite to the pair of ultrasonic generators 4. A pair of signal amplifiers 6 are installed on the inner side of the ultrasonic sleeve tube 1, and the pair of signal amplifiers 6 are respectively electrically connected to the pair of ultrasonic receivers 5.

[0023] It should be noted that, as described above, the ultrasonic sleeve 1 is made of corrosion-resistant, high-strength engineering plastic material to ensure its good stability and reliability in various environments. The ultrasonic detection structure is the core component of this ultrasonic water meter. The ultrasonic generator 4 and ultrasonic receiver 5 within the ultrasonic detection structure detect the water flow status within the pipe and are electrically connected to the central processing unit via wires. The ultrasonic generator 4 operates in a frequency range of 500kHz to 1MHz, capable of generating stable ultrasonic signals in water. The ultrasonic receiver 5 is also installed inside the ultrasonic sleeve 1, positioned opposite the ultrasonic generator 4, to receive the ultrasonic signals emitted by the generator 4. The operating frequency range of the ultrasonic receiver 5 matches that of the ultrasonic generator 4, ensuring accurate signal reception. The signal amplifier 6 is electrically connected to the ultrasonic receiver 522 to amplify the received ultrasonic signal, improving the signal-to-noise ratio and thus enhancing the accuracy and reliability of the detection. The central processing unit primarily processes the signals transmitted by the ultrasonic detection structure and uses algorithms to analyze and determine whether there is a leak in the pipe. The central processing unit uses a high-performance microprocessor, such as the ARM Cortex-M4 series, with powerful signal processing capabilities. The central processing unit (CPU) is electrically connected to the ultrasonic detection structure, wireless communication module, ANGLE sensor, and leak alarm via wires. The CPU integrates advanced signal processing algorithms, including signal preprocessing, time-of-flight (TOF) flow measurement, and leak detection algorithms. The signal preprocessing module filters out noise and interference signals to improve signal quality. The TOF flow measurement module calculates the water velocity and flow rate by measuring the time difference of ultrasonic signal propagation in the pipe. The leak detection algorithm analyzes the TOF flow measurement results to detect minute leaks in the pipe and triggers an alarm signal upon detection. The wireless communication module transmits leak information to the user's mobile device in real time. The wireless communication module supports multiple communication protocols, such as Bluetooth, Wi-Fi, and LoRa, to adapt to different usage environments and needs. In practice, the wireless communication module connects to the user's smartphone via Bluetooth, allowing the user to view the water meter's operating status and leak detection results in real time via a dedicated app. Furthermore, the wireless communication module can also connect to the user's home network or remote monitoring system via Wi-Fi or LoRa to achieve real-time monitoring and data transmission. The wireless communication module features a built-in antenna design to reduce external electromagnetic interference and ensure stable and reliable communication. The ANGLE sensor, electrically connected to the central processing unit (CPU), detects the water meter's tilt angle. The ANGLE sensor employs a high-precision triaxial accelerometer, capable of detecting the water meter's tilt angle in different directions. The CPU uses the ANGLE sensor's detection results to determine if the water meter is properly installed. If the tilt exceeds a preset angle, the CPU issues an alarm signal, reminding the user to adjust the water meter's installation position promptly.The ANGLE sensor is installed at the center of the ultrasonic sleeve tube 1 to minimize the influence of the external environment on the detection results. The leak alarm includes a high-volume buzzer and a high-brightness LED. The buzzer is designed to be above 90dB, ensuring clear audibility in noisy environments; the LED is a high-brightness red LED, making it easily visible in low-light conditions. In practice, once the central processing unit detects a leak using its algorithm, it immediately triggers the leak alarm. The buzzer emits a continuous alarm sound, and the LED flashes red until the user has resolved the issue or manually turns off the alarm.

[0024] like Figure 1-2 As shown, the protective connection structure includes: a pair of fitted toothed rings 7, a flipping L-shaped rod group 8, a flipping limiting shaft group 9, a pair of expanding telescopic shaft tubes 10, an expanding telescopic slider group 11, an expanding telescopic slide rail group 12, a pair of electromagnetic telescopic rods 13, and a linear bearing block group.

[0025] Specifically, a pair of toothed rings 7 are respectively mounted on a pair of threaded tubes 2, the flipping L-shaped rod assembly 8 is inserted into a pair of toothed rings 7 via the flipping limiting shaft assembly 9, a pair of telescopic shafts 10 are respectively movably mounted on the outside of a pair of threaded tubes 2, the telescopic slide rail assembly 12 is mounted on a pair of threaded tubes 2, the telescopic slider assembly 11 is respectively mounted on the inside of a pair of telescopic shafts 10, and the telescopic slider assembly 11 is movably inserted into the inside of the telescopic slide rail assembly 12, a pair of electromagnetic telescopic rods 13 are respectively mounted on a pair of telescopic shafts 10, and the linear bearing block assembly is respectively mounted on the outside of a pair of telescopic shafts 10.

[0026] It should be noted that, as described above, the threaded tube 2 moves horizontally and stably on the thread on the outside of the water pipe 3 via the thread. The L-shaped rod assembly 8 is rotated and flipped so that the flipped L-shaped rod rotates stably along the flipping limit axis. The telescopic slider assembly 11 on the telescopic shaft tube 10 extends and retracts horizontally along the inner side of the telescopic slide rail assembly 12. The flipped L-shaped rod is stretched to the ultrasonic sleeve tube 1. The electromagnetic telescopic rod 13 on the telescopic shaft tube 10 positions the telescopic shaft tube 10. At the same time, the toothed ring 7 is reversed and stretched and fixed in the opposite direction.

[0027] As a preferred option, the central processing unit further employs advanced signal processing algorithms, which can quickly and accurately analyze ultrasonic signals, ensuring timely detection of leaks even under complex operating conditions.

[0028] As a preferred option, the line communication module further supports multiple communication protocols and can transmit leaked information to the user's mobile device in real time, improving the timeliness and convenience of the user's response.

[0029] As a preferred embodiment, the ultrasonic sleeve tube 1 is further equipped with an ANGLE sensor, which can detect the tilt angle of the water meter, thereby further improving the stability and reliability of the water meter.
