[0038] Working principle: The floating seat 1 is suspended on the surface of the water area and can be operated by the lifting motor 6. The lifting tube 5 controls the retraction and extension of the installation tube 21 so that the installation tube 21 is located at different positions in the water area; the dissolved oxygen content in different areas of the water area, such as different corners, is different. Therefore, when performing dissolved oxygen detection, in order to ensure the accuracy of the detection result, the water area can be stirred to make the dissolved oxygen content in different areas uniform. Specifically, the extension motor 32 can be operated and the extension gear plate 33 can be rotated to move the stirring matching frame 36. At this time, the stirring matching frame 36 moves alone and extends to the outside of the installation tube 21. The driving motor 24 works and the installation tube 21 rotates to achieve stirring of the water area. The dissolved oxygen detector 23 can be used to detect the dissolved oxygen. Oxygen detection, specifically, can also synchronously remove impurities in the water area. Specifically, when the stirring matching frame 36 moves toward the outside of the mounting cylinder 21, it can drive the matching connecting plate 39 to move synchronously, that is, the buckle seat 40 is buckled with the buckle part 3601 to achieve fixation, control the motor 26 to work, control the gear ring 27 to rotate, and rotate the filter layer drum 37 to retract and release the filter layer. The filter layer extends to the outside of the mounting cylinder 21. When the mounting cylinder 21 rotates, the floating impurities can be filtered to reduce turbidity; the filter layer will recover the attached impurities, that is, roll them up on the filter layer drum 37 for subsequent processing; the control ring 30 can be controlled by controlling the electric cylinder 29 to move, and the push rod 31 can be controlled to press the top of the buckle rod 41, thereby controlling the buckle seat 40 and the buckle part 3601 in turn. The buckle state.

[0039] When further testing of the water quality is required, such as testing of heavy metals, pH value, etc., the water quality can be sampled. Specifically, sampling can be performed in different areas. The on-off is controlled by controlling valve 1 45, and the sample is transmitted to the transmission control box 46, and then transmitted to the transmission docking part 2 51 through the transmission docking box 49. The transmission electric cylinder 2 50 controls the movement of the transmission docking part 2 51, which can be docked and connected with containers 47 in different orientations, that is, the transmission docking part 2 51 is connected with the container valve 52 to transmit different samples to the container 47. The indexing motor 44 drives the indexing frame 48 to control the orientation of the transmission docking box 49.

[0040] Subsequently, the mounting cylinder 21 is lifted, and the mounting cylinder 21 is located inside the bracket 2, and the top of the mounting cylinder 21 is fixed in contact with the top of the bracket 2. The transmission docking part 8 is controlled by the transmission electric cylinder 7 to connect with the control valve 45. According to the above process, the samples in each container 47 can be transferred to the detector 4 for different detections.

[0041] Furthermore, the stirring cooperation frame 36 is controlled to move outward, and the stirring cooperation frame 36 drives the cooperation connecting plate 39 to move synchronously, so that the filter layer is extended. Through the operation of the motor 10, the screw rod 11 rotates, the slide 15 slides, and the drying part 16 is located on both sides of the filter layer to dry the filter layer. The dried filter layer can be reused and can be helpful in removing impurities attached thereto; for removing impurities, the screw rod 214 rotates and the slide 217 moves, so that the cleaning part 20 is located on both sides of the filter layer, the position of the cleaning part 20 is controlled by the position electric cylinder 18, and the cleaning motor 19 drives the cleaning part 20 to clean the impurities in the dried filter layer, and the impurities are collected by the collecting part 3.
