Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural water and various industrial drainage. Water quality monitoring can provide data and information for environmental management and provide a basis for evaluating the water quality of rivers and oceans. At present, when staff conduct water quality testing on lakes, they often use corresponding monitoring agencies, and the existing floating water quality testing equipment will effectively meet the staff's operational needs. For the existing floating water quality testing equipment, it can float on the water surface, thereby achieving the function of sustainable water body testing.

[0029] See also Figure 4 and Figure 5 The jet device 4 is annular, and there are multiple upward jet holes 5 and oblique jet holes 6 on the jet device 4. The multiple upward jet holes 5 and the multiple oblique jet holes 6 are evenly spaced. The upward jet hole 5 is arranged close to the water quality sensor 3, and the oblique jet hole 6 is arranged on the outer ring side of the upward jet hole 5.

[0030] See also Figure 2 and Figure 3The pipeline length adjustment mechanism includes a pipeline adjustment drive motor 13, the output end of the pipeline adjustment drive motor 13 is connected to a gear 14, the gear 14 is engaged with a rack 15, the rack 15 is rotatably connected to the support 16, the rack 15 is connected to a movable frame 17, the movable frame 17 is connected to a collar 19 through a connecting rod 18, the connecting rod 18 is slidably connected to the bracket 20 through a limiting groove 21, the bracket 20 is fixedly connected to the monitoring box 1, the bracket 20 is connected to the collar 19, the collar 19 is movably mounted on the air pipeline 7, and the collar 19 on the bracket 20 and the collar 19 of the connecting rod 18 are staggered.

[0031] See also Figure 1 and Figure 2 A hose is provided between the tie ring 19 and the air pipeline 7 to protect the air pipeline 7 from bending and damage, and the hose is sleeved on the outside of the air pipeline 7.

[0032] See also Figure 1 and Figure 2 The monitoring box 1 is equipped with a solar panel 22, and the solar panel 22 is connected to a battery through a converter, and the battery is used to power the monitoring system.

[0033] See also Figure 1 and Figure 2 There are multiple solar panels 22, and the multiple solar panels 22 are arranged in different directions.

[0034] In actual application, the controller controls the winding rotary motor 10 to drive the winding shaft 11 to rotate forward or reverse, retracts and releases the rope 12, and adjusts the detection depth of the water quality sensor 3, so that the water quality sensor 3 connected to the rope 12 sinks to water levels at different depths to detect water quality. The water quality detection data is wirelessly transmitted in real time to the controller for integration and processing. The controller transmits the integrated and processed data to the monitoring terminal through the wireless communication module, thereby realizing real-time online monitoring of water quality.

[0035] At the same time, the air pump 8 and the pipeline adjustment drive motor 13 are controlled to start. The air pump 8 is connected to the jet device 4 through the air pipeline 7. The jet device 4 connected to the water quality sensor 3 sprays air upward and obliquely upward, assisting the water quality sensor 3 to sink vertically. At the same time, the high-speed airflow cleans the impurities on the surface of the water quality sensor 3 and separates the aquatic plants from the water quality sensor 3, preventing the water quality sensor 3 from floating with the water flow.

When the collar 19 of the connecting rod 18 approaches the collar 19 of the bracket 20, the air pipeline 7 is lengthened. When the collar 19 of the connecting rod 18 moves away from the collar 19 of the bracket 20, the air pipeline 7 is shortened, thereby achieving the change in length of the air pipeline 7 as the rope 12 is retracted and extended;

[0037] Protect the air line 7 from bending damage by using a hose;

[0038] The ultrasonic distance measuring sensor 9 connected to the air jet device 4 detects the detection depth of the water quality sensor 3 and transmits it to the controller;
