Then, control the first motor 4 to work, drive the wire tube 6 to unwind, and drive the sampling cylinder 11 into the water body. Through the scale line on the wire tube 6, observe the depth of the sampling cylinder 11 in the water body, and sample the water quality at different depths, which improves the sampling range. Then, control the shortening of the telescopic rod of the electric push rod 1302 to drive the sealing plug 1303 to move upward, so that the sampling cylinder 11 is in an open and closed state. At this time, the water body enters the inside of the sampling cylinder 11. Then, control the elongation of the telescopic rod of the electric push rod 1302 to make the sealing plug 1303 seal the sampling cylinder 11, thus completing the sampling of the water quality. By analogy, sample the water quality of other sampling cylinders 11 respectively;

[0033] After sampling, control the first motor 4 to drive the winding disc 5 and the wire tube 6 to wind up, control the separation of the sealing plug 1303 from the sampling cylinder 11. Then, turn the set rotating cap 1204 to drive the screw 1202 to rotate, so that it separates from the clamping block 1203, and the hinged second arc-shaped plate 10 is opened to remove the sampling cylinder 11. Then, cooperate with the sealing cap to seal the sampling cylinder 11, and take the sampling cylinder 11 to a suitable place for water quality detection.
