[0023] A detection mechanism is provided at one end of the top of the floating plate 1, and the detection mechanism includes a sliding plate 20 movably connected to one end of the top of the floating plate 1 along the radial direction of the floating plate 1. Specifically, a linear guide rail 21 is provided at the corresponding position of the top of the floating plate 1 and the sliding plate 20, and the sliding plate 20 and the linear guide rail 21 are movably guided and matched.

[0024] In order to conveniently discharge the waste liquid after detection, a waste discharge port 28 corresponding to and communicating with the detection slot 25 is provided at the bottom of the detection disk 6 , and a solenoid valve is provided on the waste discharge port 28 .

[0025] In order to realize the movement of the floating plate 1, a propeller 3 is provided at the bottom of the floating plate 1. The propeller 3 is a conventional technical means and will not be described in detail: When in use, the propeller 3 can move the device to a specified position, and then control the third linear motor 9 to drive the first linear motor 5, the outer cylinder 4, the sampling rod 12, and the fixing frame 11 to move downward as a whole, and stop when moving downward to a suitable displacement, and then the first linear motor 5 drives the sampling rod 12 to move downward alone, and then the first spring 15 is compressed. The reverse force generated by the first spring 15 can increase the stability of the sampling rod 12, and then the lowest sampling storage chamber 16 first matches with the lowest through groove 13, and then the water sample at this depth enters the lowest sampling storage chamber 16, and as the sampling rod 12 moves downward, the subsequent sampling storage chambers 16 match with the corresponding through grooves 13 in turn, and then the water samples enter the sampling storage chambers 16 in turn ... The motor 5 continues to drive the sampling rod 12 to move downward until the uppermost sampling storage chamber 16 is displaced to the bottom of the uppermost through slot 13, thereby being offset from the through slot 13. At this time, the sampling storage chamber 16 is blocked, and then the third linear motor 9 drives the sampling rod 12 and the outer cylinder 4 to move upward as a whole, and then controls the second linear motor 7 to drive the sliding plate 20 to move back and forth. When the sliding plate 20 moves toward the through hole 10, the guide post 29 moves in a straight guide groove 18 close to the rack 19. At this time, the gear ring 26 meshes with the rack 19, so that the detection disk 6 rotates, and then the guide post 29 enters the inclined guide groove 30. When the guide post 29 coincides with the depression between the step 31 and the slope 32, the second spring 34 resets, and the guide post 29 falls to the depression. At this time, the detection disk 6 One end is just located in the notch 17, and at this time one of the detection slots 25 just corresponds to the uppermost through slot 13, and then the first linear motor 5 drives the sampling rod 12 to move upward, and the uppermost sampling storage chamber 16 first matches with the uppermost through slot 13, and then the water sample flows into the detection slot 25 through the through slot 13, and then is detected by the sensor 27, and then the second linear motor 7 drives the sliding plate 20 to reset, and the guide column 29 enters the straight guide slot 18 away from the side of the rack 19 through the inclined guide slot 30 under the restriction of the step 31 and the guidance of the slope 32, and then the second spring 34 is reset, and the gear ring 26 is separated from the rack 19 at this time, and when the guide column 29 reaches the depression away from one end of the through hole 10, the guide column 29 continues to fall, and then the third linear motor The machine 9 continues to drive the outer cylinder 4 and the sampling rod 12 to move upward as a whole until the notch 17 below corresponds to the detection disk 6 again, and then the second linear motor 7 continues to drive the sliding plate 20 to move in the direction of the through hole 10. Under the restriction of the step 31 and the guidance of the slope 32, the guide column 29 enters the straight guide groove 18 close to the side of the rack 19 again. At this time, the gear ring 26 meshes with the rack 19 again, so that the detection disk 6 rotates. When it reaches the depression close to the through hole 10, one end of the detection disk 6 just corresponds to the notch 17, and the detection groove 25 just corresponds to the through groove 13. Then the first linear motor 5 continues to be controlled to drive the sampling rod 12 to move upward, and then the water sample in the sampling storage chamber 16 below flows down. The cycle can realize the detection of water samples at different depths. It should be noted that, since the distance between the sampling storage cavity 16 and the corresponding through groove 13 gradually increases from bottom to top, when the sampling rod 12 moves downward, the lowest sampling storage cavity 16 first matches with the lowest through groove 13, and when the sampling rod 12 rises, the uppermost sampling storage cavity 16 matches with the uppermost through groove 13. Therefore, when sampling, the deepest water sample first enters the lowest sampling storage cavity 16, and when testing, the shallowest water sample first flows into the testing groove 25 for testing.
