Description
Technical Field
[0001] This utility model relates to the field of water accumulation monitoring technology, specifically to a water accumulation point liquid level monitoring device. Background Technology
[0002] In recent years, with the acceleration of global climate change and urbanization, flood control has become increasingly important. Ultrasonic level gauges, as a crucial tool for monitoring flood accumulation points, have seen significant technological advancements that have greatly improved the efficiency and accuracy of flood control efforts. Ultrasonic level gauges are digital level instruments controlled by microprocessors. During measurement, ultrasonic pulses are emitted by a sensor (transducer). The sound waves are reflected by the liquid surface and received by the same sensor, converted into electrical signals by a piezoelectric crystal, and the distance from the sensor to the measured liquid surface is calculated from the time between the emission and reception of the sound waves. Ultrasonic level gauges are gradually being integrated into intelligent sensor networks, enabling intelligent functions such as remote monitoring, data analysis, and fault early warning. With technological advancements, the measurement accuracy and stability of ultrasonic level gauges have been significantly improved. To meet the specific needs of different industries and scenarios, ultrasonic level gauges are developing towards customization and modularization, providing more flexible and convenient solutions.
[0003] However, in existing ultrasonic level gauges, bubbles and steam can interfere with the ultrasonic signal at water accumulation points or in drainage systems. These bubbles and steam can cause signal reflection or scattering, thus affecting the accuracy of the measurement results. Therefore, the installation of ultrasonic level gauges requires precise alignment and a stable installation position; incorrect installation angles or positions may lead to measurement errors. Consequently, in practical applications, the installation process of ultrasonic level gauges is relatively complex and requires adjustments by professionals. Furthermore, traditional ultrasonic level gauges lack wireless remote transmission capabilities, requiring manual on-site data monitoring, and they require an external power supply to operate.
