[0028] It should be noted that when the electric rotating rod 6 is started, the electric rotating rod 6 drives the driving blade 7 to rotate, and drives the connecting plate 1 to take off through the connecting ring 4 and the connecting block 3 to sample water sources in different waters;

[0029] When the device needs to sample a body of water, the electric rotating rod 6 drives the driving blade 7 to rotate to generate wind power to disperse the garbage and impurities on the water surface, preventing the impurities from adhering to the side wall of the sampling chamber 16. The first electric push rod 14 is started, and the first electric push rod 14 drives the sampling chamber 16 through the cleaning liquid chamber 15 to enter under the water surface until the sampling chamber 16 moves to the water area where sampling is required. The motor 13 is started, and the motor 13 drives the rotating blade 17 to rotate through the first electric push rod 14, the cleaning liquid chamber 15 and the sampling chamber 16 to stir the water area and shake off the water source impurities. The solenoid valve 19 is opened, and the water pump 21 is started. The water pump 21 pumps the water source of the water area into the sampling chamber 16 through the sampling pipe 18 to complete the sampling. The first electric push rod 14 is started, and the first electric push rod 14 drives the sampling chamber 16 to reset through the cleaning liquid chamber 15.

The water pump 21 is started, and the water pump 21 transports the sampled water inside the sampling chamber 16 into the storage test tube 44 through the telescopic water pipe 22;

[0030] When the sampling water is completely injected into the storage test tube 44, the electric telescopic tube 45 is started, and the electric telescopic tube 45 presses down on the side wall of the storage test tube 44. The second electric push rod 28 is started, and the second electric push rod 28 drives the sealing plug 26 to move into the electric telescopic tube 45 through the push plate 30. Due to the setting of the electric telescopic tube 45, the sealing plug 26 is limited, so that the sealing plug 26 can enter the storage test tube 44 under the influence of gravity. The third electric push rod 46 is started, and the third electric push rod 46 drives the pressing plate 47 to press down to squeeze the sealing plug 26 into the storage test tube 44 to seal it, improving its storage time. When the third electric push rod 46 squeezes the sealing plug 26, it drives the sliding circular plate 24 to slide downward, and the sliding circular plate 24 drives the fixed cone 25 to press down to pierce the preservative bladder 27. The preservative inside the preservative bladder 27 enters the sampled water inside the storage test tube 44, further improving the storage time of the sampled water. Through the setting of the detector 23, the sealing plug 26 inside the limiting tube 33 is detected. When the sealing plug 26 inside the limiting tube 33 is used up, a reminder is sent to the operator to prevent the operator from not knowing whether the sampling water has been completely injected into the storage test tube 44 inside the device. Through the setting of the telescopic plate 29, when the push plate 30 drives one sealing plug 26 to move, the other sealing plugs 26 are supported;

[0031] After a storage test tube 44 is sealed, the electric telescopic tube 45 is closed, and the electric telescopic tube 45 resets. Then, the motor 13 is started. The motor 13 drives the storage test tube 44 to rotate for automatic replacement through the first electric push rod 14, the small gear 37, the large gear 39, the toothed ring 40, the storage box 34, the electromagnetic ring 35, the water filter plate 36, and the fixed bin 43, enabling the device to classify and store water sources in different areas. At the same time, the cleaning liquid bin 15 is started, and the cleaning liquid bin 15 inputs the cleaning liquid into the sampling bin 16. When the first electric push rod 14 rotates, it drives the sampling bin 16 to rotate, allowing the cleaning liquid to thoroughly clean the inside of the sampling bin 16. The solenoid valve 19 is opened, and the cleaning liquid is discharged from the inside of the sampling tube 18, preventing the mixing of water sources in different areas inside the sampling bin 16 and avoiding errors when subsequent devices detect the water quality of the water area.

[0038] In an alternative embodiment: A plurality of rotating blades 17 are fixedly connected to the side wall of the sampling bin 16, and the plurality of rotating blades 17 are arranged at equal intervals.

[0039] It should be noted that the cooperation of the plurality of rotating blades 17 can stir the water area and prevent impurities in the water area from entering the inside of the sampling bin 16.

[0040] In an alternative embodiment: A filter screen 20 is fixedly connected to the inner wall of the sampling tube 18, the telescopic water pipe 22 passes through the sampling bin 16, and the telescopic water pipe 22 passes through the cleaning liquid bin 15.

[0046] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0047] During operation, the electric rotating rod 6 is started. The electric rotating rod 6 drives the driving blade 7 to rotate, and through the connecting ring 4 and the connecting block 3, drives the connecting plate 1 to take off for water sampling in different water areas.

[0048] When the device needs to sample a water area, the electric rotating rod 6 drives the driving blade 7 to rotate to generate wind power to disperse the garbage impurities on the water surface to prevent the impurities from adhering to the side wall of the sampling chamber 16. The first electric push rod 14 is started. The first electric push rod 14 drives the sampling chamber 16 into the water through the cleaning liquid chamber 15 until the sampling chamber 16 moves to the water area where sampling is required. The motor 13 is started. The motor 13 drives the rotating blade 17 to rotate through the first electric push rod 14, the cleaning liquid chamber 15 and the sampling chamber 16 to stir the water area and shake off the water source impurities. The solenoid valve 19 is opened, and the water pump 21 is started. The water pump 21 pumps the water source in the water area into the sampling chamber 16 through the sampling pipe 18 to complete the sampling. The first electric push rod 14 is started.

The telescopic water pipe 22 extends into the storage test tube 44. The water pump 21 is started. The water pump 21 transports the sampled water in the sampling chamber 16 into the storage test tube 44 through the telescopic water pipe 22.

[0049] After the sampling water is completely injected into the storage test tube 44, start the electric telescopic tube 45. The electric telescopic tube 45 presses down to the side wall of the storage test tube 44. Start the second electric push rod 28. The second electric push rod 28 drives the sealing plug 26 to move into the electric telescopic tube 45 through the push plate 30. Due to the setting of the electric telescopic tube 45, the sealing plug 26 is limited, so that the sealing plug 26 can enter the storage test tube 44 under the influence of gravity. Start the third electric push rod 46. The third electric push rod 46 drives the extrusion plate 47 to press down to extrude the sealing plug 26 into the storage test tube 44 to seal it, improving its storage time. When the third electric push rod 46 extrudes the sealing plug 26, it drives the sliding circular plate 24 to slide downwards. The sliding circular plate 24 drives the fixed cone 25 to press down to pierce the preservative bladder 27. The preservative inside the preservative bladder 27 enters the sampling water inside the storage test tube 44, further improving the storage time of the sampling water. Through the setting of the detector 23, the sealing plug 26 inside the limiting tube 33 is detected. When the sealing plug 26 inside the limiting tube 33 is used up, a reminder is sent to the operator to prevent the operator from not knowing whether the sampling water has been completely injected into the storage test tube 44 inside the device. Through the setting of the telescopic plate 29, when the push plate 30 drives one sealing plug 26 to move, the other sealing plugs 26 are supported;

[0050] After a storage test tube 44 is sealed, turn off the electric telescopic tube 45. The electric telescopic tube 45 resets. Start the motor 13.

At the same time, start the cleaning liquid bin 15. The cleaning liquid bin 15 inputs the cleaning liquid into the sampling bin 16. When the first electric push rod 14 rotates, it drives the sampling bin 16 to rotate, so that the cleaning liquid can clean the inside of the sampling bin 16 comprehensively. Open the solenoid valve 19, and the cleaning liquid is discharged from the sampling tube 18 to prevent the mixing of water sources in different areas inside the sampling bin 16 and avoid errors when the subsequent device detects the water quality of the water area.
