The top cover 4 is clamped inside the card slot 2 through the limiting plate 3. Rotate the baffle plate 5 to make it abut against the limiting plate 3 to limit and fix the top cover 4. Thread the limiting bolt 7 into the corresponding two limiting holes 6 to limit and fix the baffle plate 5, making the top cover 4 a detachable structure, which is convenient for replacement and maintenance, increasing the practicability of the device. The water quality is sampled in layers through a plurality of transparent bottles 8 to avoid mixing between samples and improve the accuracy of detection. The transparent bottle 8 is threadedly connected inside the top cover 4, which is convenient for installation and disassembly, facilitating the removal of the sample after sampling and also convenient for cleaning to avoid the remaining sample affecting the next sampling and detection.

[0029] In this embodiment, a housing 9 is fixedly connected to the middle of the lower surface of the fixing base 1, and an air pump 10 is fixedly connected to the inner bottom wall of the housing 9.

[0030] During specific use, through the settings of the housing 9 and the air pump 10, the housing 9 is used to support and fix the air pump 10, sealing the air pump 10 inside the housing 9 to prevent the air pump 10 from getting water when the device enters the water, enhancing the protection performance.

[0031] In this embodiment, a fixed pipe 11 is fixedly connected to the output end of the air pump 10, and a flow splitter 12 is fixedly connected to one end of the fixed pipe 11.

[0032] During specific use, through the setting of the flow splitter 12, the flow splitter 12 is used to fix a plurality of tracheas 13 for splitting, enabling a plurality of tracheas 13 to all perform air extraction.

[0033] In this embodiment, a trachea 13 is fixedly connected inside the flow splitter 12, and the trachea 13 is movably connected to the top cover 4.
