[0028] Exemplarily, as Figure 3 and Figure 5 shown, a chute 14 is opened in the installation box 2. The bottom of the chute 14 is communicated with the installation cavity 4. A lead screw 15 is rotatably connected in the chute 14. A first motor 16 is arranged at one end of the installation box 2. The output end of the first motor 16 penetrates through the installation box 2 and is drivingly connected to the lead screw 15. A slider 17 is threadedly connected to the lead screw 15. The slider 17 slides in the chute 14. A connecting plate 18 is arranged in the installation cavity 4. The bottom of the slider 17 is installed on the top of the connecting plate 18. An electric sliding table 19 is embedded at the bottom of the connecting plate 18. A connecting block 20 is installed on the output end of the electric sliding table 19. A conveying pipe 21 is arranged on the connecting block 20. The input end of the conveying pipe 21 is communicated with a spiral telescopic pipe 36.

[0029] Exemplarily, as Figure 3 and Figure 4As shown in the figure, a mounting seat 22 is installed on the top of the base 1. A rotating rod 23 is rotatably connected inside the mounting seat 22. One end of the mounting seat 22 is provided with a second motor 24. The output of the second motor 24 penetrates through the mounting seat 22 and is drivingly connected to the rotating rod 23. A conveying pipe 25 is wound around the rotating rod 23. A connecting pipe 26 is arranged above the mounting seat 22. The output end of the conveying pipe 25 is connected to the input end of the connecting pipe 26 through a flange. The output end of the connecting pipe 26 penetrates through the base 1 and is connected to a spiral telescopic pipe 36. A water pump 27 is arranged on the connecting pipe 26.

[0030] For a water quality detection device at different depths in a water conservancy project proposed by the present invention, its working principle is as follows: When the second motor 24 is started to drive the rotating rod 23 to rotate, the water inlet pipe 28 is driven to descend at the same time, and it can be adjusted to different water depth positions according to needs, collect water samples at different depths, and provide more comprehensive and accurate water quality data.

[0031] When the water pump 27 is started, when water enters the water inlet pipe 28, impurities are filtered through the filter screen 30, and then pass through the conveying pipe 25, the connecting pipe 26 and the spiral telescopic pipe 36 in sequence and are output by the conveying pipe 21. After discharging a part of the water each time, the electric sliding table 19 is started to drive the connecting block 20 to move and drive the conveying pipe 21 to move at the same time, and the output end of the conveying pipe 21 is placed directly above one of the detection boxes 10, and the water source enters the detection box 10.

[0032] When the first motor 16 is started to drive the lead screw 15 to rotate, the slider 17 is driven to move at the same time. The slider 17 drives the connecting plate 18 to move and drives the connecting block 20 and the conveying pipe 21 at the same time, and the water taken at different depths is conveyed to different detection boxes 10 for detection by the water quality detector body 11.

[0033] After the detection is completed, the second electric valve 13 is started, and the water in the detection box 10 is output to the collection cavity 6 through the output pipe 12.

[0034] When extracting water sources, the third motor 32 is started. While the third motor 32 drives the connecting column 33 to rotate, it also drives the scraper 34 to move. The scraper 34 scrapes off the impurities on the filter screen 30, preventing blockage, achieving a cleaning effect and facilitating subsequent sampling.

[0035] Both ends of the transport pipe 25 are respectively flange-connected to the water inlet pipe 28 and the connecting pipe 26, and can be disassembled for easy replacement.

[0036] When water enters the water inlet pipe 28, impurities are filtered by the filter screen 30. At the same time, the third motor 32 is started. While the third motor 32 drives the connecting column 33 to rotate, it also drives the scraper 34 to move. The scraper 34 scrapes off the impurities on the filter screen 30, preventing blockage, achieving a cleaning effect and facilitating subsequent sampling, improving work efficiency and ensuring the accuracy of analysis at the same time.

[0037] Both ends of the transport pipe 25 are respectively flange-connected to the water inlet pipe 28 and the connecting pipe 26, and can be disassembled for easy replacement, extending the service life of the equipment and improving convenience.

[0038] Multiple detection boxes 10 are provided, and each detection box 10 is equipped with an independent water quality detector body 11, which can detect the water quality at different depths simultaneously, ensuring the integrity and accuracy of the data.
