The external remote control and the wireless remote control switch cooperate to remotely control the electric telescopic rods 6. The utility model can achieve the purpose of sampling at multiple locations at a single fixed depth through the setting of a series of structures. There is no need for personnel to operate multiple times, which improves the sampling efficiency. It can also avoid the mixing of multiple water samples during the sampling process, thereby improving the sampling accuracy. In addition, after sampling, the four water storage tanks 1 can be cleaned at the same time without the need for personnel to manually scrub them, which improves the cleaning efficiency and reduces the labor intensity.

[0026] Working principle: When in use, the opening stroke time and the reverse opening time of the four electric telescopic rods 6 are set in advance through the controller 7. When performing the sampling operation, the entire device can be lowered into the required lake water through the scale rope 17, and at the same time, the gravity of the counterweight block 10 is used to enable the entire device to move downward smoothly. During the lowering process, the position of the sampling seat 100 is judged by observing the scale line on the scale rope 17. When it moves to the required position, the lowering of the scale rope 17 can be stopped, and then one of the electric telescopic rods 6 is remotely controlled to open in the forward direction through the external remote control and the controller 7. The output shaft of one of the electric telescopic rods 6 drives the corresponding L-shaped The blocking plate 4 moves upward, and the L-shaped blocking plate 4 drives the corresponding positioning rod 5 to move upward. The L-shaped blocking plate 4 moves upward and releases the blockage of the corresponding water pipe 2. When the opening travel time reaches a preset value, the blockage of the water pipe 2 is completely released. At this time, the controller 7 controls one of the electric telescopic rods 6 to close. At this time, under the action of water pressure, the lake water enters the water storage tank 1 through the corresponding water pipe 2. At the same time, the filter screen 3 filters and blocks impurities in the flowing water. Fifteen seconds after the water pipe 2 is opened, the controller 7 controls one of the electric telescopic rods 6 to start in the reverse direction, so that the L-shaped blocking plate 4 is converted to move downward to block the corresponding water pipe 2 again;

[0027] Then the entire device can be lowered further using the graduated rope 17. When it reaches the required depth, the same method as above is used to sample the next water tank 1. Similarly, when the sampling of the four water tanks 1 is completed, the graduated rope 17 can be pulled upward to remove the entire device from the lake water. By coordinating the four water tanks 1, the four water pipes 2, and the four blocking mechanisms, the purpose of sampling multiple locations at a single fixed depth can be achieved. There is no need for personnel to operate multiple times, which improves the sampling efficiency. In addition, during the sampling process, the mixing of multiple water samples can be effectively reduced, thereby improving the sampling accuracy.

[0028] After sampling, when the sample needs to be taken out, the electric telescopic rod 6 can be started forward again to release the blockage of the water pipe 2, so that the water inside the water storage tank 1 is discharged to the outside through the corresponding water pipe 2. After the sample is discharged, when cleaning the water storage tank 1, the blocking cover can be removed from the extraction end of the water pump 11, and the extraction end is connected to the external water suction pipe and inserted into the external clean water tank, and the water pump 11 is turned on. The water pump 11 extracts the water inside the clean water tank through the extraction end, and the extracted water is sequentially passed through the vertical pipe 12 and the horizontal pipe 9 into the four water spray pipes 13. The water inside the water spray pipe 13 is sprayed out through the corresponding multiple water spray heads 14 and the one-way valve to flush the water storage tank 1, and the flushing water is discharged through the water pipe 2, thereby achieving the purpose of cleaning the four water storage tanks 1 at the same time, without the need for manual scrubbing by personnel, improving cleaning efficiency and reducing labor intensity.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
