The limiting ring 20 is arranged on the upper partition 4, the water suction pipe 11 is arranged in the limiting ring 20, and the limiting ring 20 limits and guides the water suction pipe 11

[0026] Working principle:

[0027] The water pump 8 extracts water samples from the designated water source through the water suction pipe 11. The extracted water samples are sent into the infusion pipe 5 by the water pump 8 and are distributed to each branch pipe 6 through the infusion pipe. Each branch pipe 6 is equipped with an electromagnetic valve 7, and the controller 10 controls the opening and closing of the electromagnetic valve according to the preset program, thereby controlling whether the water sample enters the corresponding collection tank 3. The water sample is accurately distributed to each collection tank 3, and each collection tank 3 corresponds to a different sampling depth or time point, facilitating subsequent water quality analysis and comparison. After sampling is completed, the operator can take out the water sample in the collection tank 3 for laboratory analysis.

[0028] In this way, the water quality environmental protection experiment collection box can effectively collect water samples at different depths and times, providing an efficient and automated tool for water quality monitoring and environmental protection research.

[0029] Specifically, the wire laying device 12 includes a winding motor 121 fixedly installed on the inner wall of the box body 1, and a wire laying wheel 122 fixedly connected to the output shaft of the winding motor 121. The water suction pipe 11 is wound around the wire laying wheel 122. The winding motor 121 is a reversible motor, which drives the wire laying wheel 122 to rotate forward or reverse, thereby winding or unwinding the water suction pipe 11 to meet different length requirements. The end of the water suction pipe 11 away from the water pump 8 is fixedly connected with a hollow counterweight 13, the surface of the hollow counterweight 13 is provided with a water inlet, and the water inlet is provided with a filter screen 14. When extracting water samples, the hollow counterweight 13 can sink to a suitable depth in the water body, and the filter screen 14 can prevent larger impurities in the water from entering the water suction pipe 11 and blocking the pipeline, thereby ensuring the smoothness of water extraction. The outer side of the box body 1 is fixedly connected with a protective cover 15 corresponding to the hollow counterweight 13, which serves to isolate and protect the hollow counterweight 13.

The sealing plug 16 ensures the sealing property of the collection tank 3, preventing water sample leakage or external air from entering the collection tank 3 and affecting the properties of the water sample. The branch pipe 6 is designed as a telescopic structure, which facilitates the removal of the sealing plug 16.

[0031] In addition, the placing groove 2 is provided with a sponge pad 17, which can buffer and protect the collection tank 3, reduce the vibration and impact of the collection tank 3 during transportation or movement, and protect the water sample in the collection tank 3 and the collection tank 3 itself from being damaged.
