A pin 11 adapted to the fixing hole 34 is arranged in the stabilizing block 10. The fixing block 31 is fixed by the pin 11 to prevent sliding.

[0023] An extension column 4 is arranged on the surface of the fixing seat 3. There are multiple extension columns 4 and they are fixedly connected in sequence along the axial direction of the extension column 4. The bottom end of the bottom extension column 4 is fixedly connected to a detection column 5. The extension column 4 and the detection column 5 are made of metal pipes and an anti-corrosion layer is arranged on the surface. The service life is improved through the design of the anti-corrosion layer. There are multiple detection columns 5 and they are fixedly connected in sequence along the axial direction of the detection column 5. A through hole is arranged in the center of the extension column 4 and the detection column 5. The water level sensor 12 is arranged inside the detection column 5. There are multiple water level sensors 12 and they are equidistantly arranged along the axial direction of the detection column 5.

[0024] Specific extension column 4 includes a first pipe body 41. At the top end of the first pipe body 41, a first mounting block 42 is fixedly connected. At the bottom end of the first mounting block 42, a convex surface adapted to the concave surface 32 is provided. In the middle of the first mounting block 42, a through first threaded hole 43 is provided. At the bottom of the surface of the first pipe body 41, a first external thread 44 is provided. On the surface of the first pipe body 41 and on one side close to the first external thread 44, a first limiting mechanism 45 is provided. On one side of the top of the first mounting block 42, a first limiting groove 46 adapted to the first limiting mechanism 45 is provided. When multiple extension columns 4 are connected, the first external thread 44 is threadedly connected to the first threaded hole 43 on another extension column 4;

[0025] The detection column 5 includes a second pipe body 51. At the top end of the second pipe body 51, a second mounting block 52 is fixedly connected. In the middle of the second mounting block 52, a through second threaded hole 53 is provided. At the bottom of the surface of the second pipe body 51, a second external thread 54 is provided.

[0026] Among them, the first limiting mechanism 45 and the second limiting groove 56 have the same size. The first limiting mechanism 45 includes a fixed groove 451. Inside the fixed groove 451, a limiting block 452 is slidably connected. The sliding direction of the limiting block 452 is parallel to the axial direction of the first pipe body 41. After threaded connection, by sliding one end of the limiting block 452 and inserting it into the limiting groove, relative rotation is avoided. To prevent the limiting block 452 from loosening, a spring is provided between the top of the limiting block 452 and the inner wall of the fixed groove 451.

[0027] At the top of the fixed frame 2, an equipment box 9 is provided. The data transmission module is arranged in the equipment box 9. Multiple water level sensors 12 are electrically connected to the data transmission module, and the data transmission module is communicatively connected to the data processing platform.

[0028] Each water level sensor 12 is connected to the data transmission module, which is responsible for uploading the water level data collected by each sensor to the data processing platform in real time. The data transmission module uses the TCP / IP or UDP data transmission protocol to ensure the real-time and accuracy of the data. The data transmission process is as follows:

[0029] Sensor data reading: The transmission module periodically sends data requests to the sensors, or receives the data actively sent by the sensors;

[0030] Data encapsulation: Encapsulate the read water level data according to a specific protocol format, including information such as sensor identification, water level value, timestamp, etc.;

[0031] Error detection and correction: Before data transmission, apply an appropriate error detection algorithm (such as CRC check) to ensure data integrity;

[0032] Data transmission: Send the encapsulated data to the data processing platform via wired or wireless means (such as RS485, LoRa, NB-IoT, etc.).

[0033] The data processing platform processes the water level data received from the data transmission module. Through data analysis and processing, a water level change curve graph is generated to provide a decision-making basis for water resource management. The data processing and analysis process is as follows:

[0034] Data reception: The system receives data packets from the transmission module through a specific data interface;

[0035] Data de-encapsulation: Parse the received data packet according to the protocol format and extract information such as sensor identification, water level value, timestamp, etc.;

[0036] Data cleaning and verification: Clean the parsed data, remove outliers or incorrect data, and perform necessary verification;

[0037] Data storage: Store the cleaned data in a database for subsequent analysis and query.

[0038] Data analysis: Use methods such as statistics and time series analysis to deeply analyze the water level data to understand the laws and trends of water level changes;

[0039] Data display: Visualize the analysis results through forms such as charts and reports for users to intuitively understand the water level situation.

[0040] Abnormal alarm: Set a water level threshold. When the water level data exceeds or is lower than the threshold, the system triggers an alarm mechanism and notifies relevant personnel through means such as sound, text message, and email.

[0041] For the specific data processing platform, a commercially available mature and stable data processing software or cloud platform can be selected. For example, the Pingsheng Electronic Groundwater Online Monitoring and Management Platform developed by Tangshan Pingsheng Electronic Technology Development Co., Ltd. or the Hengrun'an Water Conservancy Industry Comprehensive Management Platform developed by Beijing Hengrun'an Technology Co., Ltd. Its water level sensors and data transmission modules use their corresponding products, which are existing technical solutions and will not be elaborated here.

[0042] The data processing platform improves the intelligent level of water resource management and reduces the need for manual intervention.

[0043] On both sides of the inner wall of the fixing frame 2, there are slidingly connected guiding blocks 6. Between the two guiding blocks 6, there is a fixed connection of a lifting seat 7. At the center of the lifting seat 7, there is a fixed screw 13. The specification of the fixed screw 13 is the same as that of the first external thread 44, and it can be threadedly connected to the tops of the extension column 4 and the detection column 5. On both sides of the top of the fixing frame 2, there are fixed connections of winches 8. The cable ends of the winches 8 are fixedly connected to the tops of the guiding blocks 6. Inside the equipment box 9, there is a controller for controlling the winches 8.

[0044] When it is necessary to increase the length of the extension column 4, first install the newly added extension column 4 on the top of the extension column 4. Subsequently, the lifting seat 7 descends to a suitable position, and the fixed screw 13 is rotated to connect the fixed screw 13 with the newly added extension column 4. Subsequently, the lifting seat 7 moves upward a certain distance so that there is no pressure on the top of the fixed seat 3. The pin 11 is pulled out, and the two fixing blocks 31 are slid. Subsequently, the lifting seat 7 descends, and the newly added extension column 4 falls into the hole. Subsequently, the two fixing blocks 31 are reset and fixed by the pin 11. The mounting block one of the newly added extension column 4 is placed on the top of the fixed seat 3. Subsequently, the fixed screw 13 is rotated to separate the fixed screw 13 from the extension column 4. During the installation process, tools such as pipe wrenches can be used for operation.
