Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically to a prototype monitoring device for non-steady flow water level fluctuations in rivers. Background Technology

[0002] Currently, the frequency and timing of routine river level observations are generally based on the principle of being able to measure the complete water level change process. When the water level is stable or changes slowly, observations are generally conducted once every 8 hours; when the water level changes significantly, observations are conducted 4 times a day; during the flood season when the water level changes drastically, the frequency of observations is increased as needed to measure the flood peak, trough water level, and the entire flood process.

[0003] To meet power generation demands, some hydropower station units will perform peak shaving or switching operations during operation according to grid dispatch requirements. This will cause rapid changes in downstream flow, inevitably resulting in unsteady flow phenomena in the downstream river channel and navigation channel. This leads to significant fluctuations in river and navigation channel water levels within minutes, which have a substantial impact on navigation facilities and vessel safety. The accuracy of conventional river water level monitoring data is insufficient to provide safety warnings for the safe operation of navigation facilities and vessel navigation in downstream waters under these special conditions.

[0027] Preferably, the data acquisition unit 5 is connected to the serial port server 6 in the data acquisition box 2.

[0028] Preferably, the data acquisition box 2 is equipped with a signal surge protector 8.

[0029] In this embodiment, the signal surge protector 8 prevents lightning strikes from damaging the equipment and improves the reliability of the device in severe weather.

[0030] Preferably, the solar power supply device includes a solar panel 1, a solar charge controller 7, and a PoE power supply 10, and the solar power supply device is installed in the data acquisition box 2.

[0031] In this embodiment, the solar power supply device integrates a PoE power supply 10, which can work continuously in areas without power grids, solving the power supply problem for long-term outdoor monitoring.

[0033] In this embodiment, the combination of a high-precision dynamic monitoring millimeter-level water level gauge and a second-level data acquisition frequency solves the problem of insufficient conventional observation accuracy in the background technology. It can capture large water level fluctuations (such as ±1 meter fluctuations) within a few minutes during peak shaving of hydropower stations, providing real-time safety early warning data for navigation facilities.

[0034] Preferably, the data collector 5 has a data storage module.

[0035] In addition, the storage module of the data acquisition device 5 in this application automatically caches data when the wireless signal is interrupted to avoid monitoring interruption.

[0036] The wireless transmission device is equipped with an automatic delayed transmission function to prioritize uploading data during periods of high fluctuation in response to sudden operating conditions such as load shedding at hydropower stations, ensuring that critical early warning information is not lost.

[0039] The optimized implementation of the water level acquisition device is to use a radar sensor for the water level gauge 4, which avoids interference from river debris through non-contact measurement, and to combine it with the RTU data acquisition unit 5 to achieve signal filtering and improve the stability of millimeter-level data.

[0040] Among them, the 4G router 9 and the wireless bridge 3 form a dual-channel transmission: when the 4G network coverage is insufficient, it automatically switches to the wireless bridge 3 for point-to-point transmission, ensuring the continuity of the second-level data transmission frequency.
