[0041] Example 4

[0042] The fourth embodiment of this utility model provides a technical solution: between the sealed bottom cover 6 and the filter protection cylinder 8, an O-ring (such as EPDM material) is added to improve the waterproof performance of the mounting groove 7 and prevent water from entering and damaging the drive motor 14.

[0045] Working principle:

[0046] The working principle of the water quality analysis device for river management is as follows: A buoyancy platform 1 floats on the water surface, providing buoyancy support for the device. A solar panel 2 is fixed to the top of the buoyancy platform 1 via a support frame 3, converting solar energy into electrical energy to power the device. A handle 4 facilitates the handling and deployment of the device. A rotary drive assembly is installed in the mounting groove 7 at the bottom of the buoyancy platform 1. The drive motor 14 of this assembly drives the sprocket 12 to rotate via a chain 13, which in turn drives the rotating sleeve 11 to rotate around the vertical fixed rod 9. The rotating sleeve 11 drives the sliding rod 16 to rotate via a transverse guide frame 17, causing the L-shaped cleaning scraper 15 to perform a circular cleaning motion on the inner wall of the filter protection cylinder 8. The sliding rod 16 slides within the groove 18 of the transverse guide frame 17, and a return spring 19 maintains a tight fit between the L-shaped cleaning scraper 15 and the inner wall of the filter protection cylinder 8, ensuring effective cleaning. The filter protection cylinder 8 is detachably connected to the buoyancy platform 1 via a closed bottom cover 6, protecting the probe 10 on the inner wall from impacts by foreign objects in the water and facilitating disassembly and maintenance. The probe 10 detects water quality parameters in real time, and the data is transmitted to the analysis module on the buoyancy platform 1 via a built-in line (not mentioned in the claims, but is an essential component of the device).

[0047] In summary, the sieve structure of the filter protective cylinder 8 ensures water flow while blocking large particles and floating objects, thus extending the service life of the probe 10.
