Detailed Implementation
[0025] The present invention will be further described below with reference to specific embodiments.
[0026] like Figures 1-7 As shown, the bridge water level measuring device of this utility model includes a connecting plate 11 for connecting with external equipment. In this embodiment, the connecting plate 11 is provided with three connecting bolts 12, thereby the connecting plate 11 can be fixedly installed at a suitable measuring position.
[0027] The connecting plate 11 is also connected to a water flow detection component 1, which includes a drain frame 13 connected to the connecting plate 11. The drain frame 13 is a hollow frame for water flow. A water flow counter 131 is located at the bottom of the drain frame 13. A straight shaft 132 is located on the water flow counter 131, and several impellers 133 arranged in a circular array are located on the straight shaft 132. The rotation path of the impellers 133 partially covers the path of the water flow through the drain frame 13. Therefore, when water flows through the drain frame 13, the impellers 133 will rotate, thereby driving the water flow counter 131 to count, realizing real-time monitoring of water flow.
[0028] On the other side of the drain frame 13, a water level detection component 2 is connected. Specifically, the water level detection component 2 first includes a cylindrical connecting frame 21 fixedly connected to the drain frame 13. Inside the connecting frame 21, a sliding shaft 23 is provided, with its top end near the bottom of the connecting frame 21 and extending downwards to the outside of the connecting frame 21. Outside the sliding shaft 23, a similarly vertical cylindrical limiting frame 22 is wrapped around it, extending from the bottom end of the connecting frame 21, to limit the range of movement of the sliding shaft 23.
[0029] At the bottom of the sliding shaft 23, a water inlet filter frame 27 is provided, which can filter impurities. Four evenly distributed buoyancy balls 24 are also provided at the bottom of the sliding shaft 23. When the water level changes, the buoyancy balls 24 will drive the sliding shaft 23 to move up and down. A top rod 25 is fixedly connected to the top of the sliding shaft 23 to transmit water level change signals. Similarly, inside the connecting frame 21, above the top rod 25, four sliding blocks 26 are provided. These four sliding blocks 26 are slidably assembled in an equidistant manner, and an auxiliary component 4 is fixedly connected to the top of each sliding block 26. Specifically, a sliding spring 261 is connected between the sliding block 26 and the inner wall of the connecting frame 21. Dampers 262 are provided at both ends of the sliding spring 261 to stabilize the movement of the sliding block 26 and absorb impacts. Point contacts 263 are installed on both the sliding block 26 and the connecting frame 21 to output electrical signals indicating water level changes.
[0030] On the outside of the limiting frame 22, an anti-collision component 3 is also provided, which includes a double-layer protective frame 33, also cylindrical in shape. The outer wall of the inner layer of the double-layer protective frame 33 is uniformly provided with several vertically arranged inner groove frames 31. In this embodiment, there are four inner groove frames 31, and several equidistantly distributed shock-absorbing springs 32 are provided within each inner groove frame 31. Protective blocks can be provided on the outer ends of the shock-absorbing springs 32 to absorb impact energy. When the device is impacted, the shock-absorbing springs 32 and the protective blocks will work together to absorb and disperse the impact force, protecting the main body of the device from damage.
[0031] Auxiliary component 4 includes a warning light 41 mounted on top of the connecting frame 21, and a solar panel 42 mounted on top of the warning light 41. Additionally, a signal receiving module 43 and a battery module 44 are mounted on both sides of the drainage frame 13. Thus, the warning light 41 can emit a warning signal when the water level is abnormal or the device malfunctions. The solar panel 42 provides green and clean energy for the device. The signal receiving module 43 adopts a B / S architecture design, and its functions include receiving rainfall data, receiving water level data, sending flood alarm SMS messages, querying flood data, managing the backend system, and accessing the Nantong Railway Flood Control App. Daily rainfall data from the water level point and three nearby rainfall monitoring points were collected to construct a dataset for LSTM model training. The experimental design included data preprocessing, model building, and a control experiment. During data preprocessing, the raw data was standardized to eliminate the impact of data volume on the model's prediction accuracy. During model building, a multi-layer LSTM neural network was built using Python and PyTorch frameworks for model training and parameter adjustment. The control experiment was divided into two groups. The first group used only water level information, while the second group combined rainfall information to verify the impact of different feature combinations on the prediction effect. This allows for viewing data on a single table and screen, solving the problem of having to access several devices to view rainfall data for high-speed rail. After the project is completed, various statistical data will be automatically generated through the system, greatly improving work efficiency, reducing labor intensity, and saving flood control personnel. For bridges equipped with water level monitoring equipment, it will be unnecessary to send personnel to measure water levels during disasters, reducing the danger to workers. All of the above can implicitly save labor costs and provide possibilities for personnel conservation. At the same time, with the establishment of flood control big data analysis models, scientific decision-making basis will be provided for flood control work, making the input of human and material resources more precise and efficient, and train operation organization more orderly and efficient.
