[0015] 1. The lower shell and the upper shell are sealed together and float on the water surface. When sampling and testing the water quality, the working motor will use the rotating output shaft to drive the winding shaft to rotate synchronously, and the water pumping pipe wound on the winding shaft can be released. With the release of the water pumping pipe, the length of the water pumping pipe that can enter the water body is increased. Then, one end of the water pumping pipe will quickly dive to the deep water area driven by multiple spliced ​​folding plates and adsorption folding plates. When the water pumping pipe dives to the predetermined position and samples, the interception net fixed on the bottom of the blocking frame can prevent algae or fish in the water from entering the water pumping pipe, so as to prevent the water quality test results from being affected. The staff can control the number of rotations of the winding shaft by controlling the working time of the motor, and then control the depth of the water pumping pipe in the water body, which is convenient for sampling water bodies at different depths, increases the amount of data that can be obtained when sampling water quality detection, and increases the accuracy of the test results in the entire environment;

[0016] Second, when the lower shell and the upper shell are fixed together and float on the water, since a counterweight column is installed on the inner bottom surface of the lower shell, the total weight of the lower shell is greater than the total weight of the upper shell due to the existence of the counterweight column, which can ensure that most of the lower shell is vertically immersed in the water to avoid inversion. When the water quality monitoring device floats on the water, the anchor rope connected to the bottom of the lower shell will connect to the fixed anchor and sink to the bottom of the water, which can limit the water quality monitoring device to float within a certain range on the water surface, preventing the water quality monitoring device from moving with the flowing water and being lost;

[0017] 3. The hollow floating column will cooperate with the cavities inside the lower shell and the upper shell to increase the buoyancy of the lower shell on the water surface, preventing the lower shell from sinking due to insufficient buoyancy. When the floating column floats on the water surface, the photovoltaic panel will be directly exposed to the sun, and the photovoltaic panel will be used to charge the power supply, thereby extending the working time of the water quality detector;

[0018] 4. When the lower shell and the upper shell are fixed together, the threaded ring will be screwed into the inside of the threaded groove, and at the same time, the bottom surface of the threaded ring will be squeezed and contacted with the top surface of the sealing ring, thereby increasing the sealing between the lower shell and the upper shell and preventing water seepage.
