[0001] The utility model relates to the technical field of environmental detection, in particular to a water quality sampling device for environmental detection. Background Technique

[0002] Environmental detection is a new and emerging industry with strong technicality. Among them, the detection of water quality is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status.

[0003] A Chinese patent discloses a water quality sampling device with the publication number CN214277544U, which includes a base. The middle end of the upper surface of the base is fixedly connected with a shell. The lower end of the front surface of the shell is provided with a sampling port. The upper end of the right side of the shell is fixedly connected with a motor box. The middle end of the left side of the inner cavity of the motor box is fixedly connected with a servo motor. The output end of the servo motor penetrates through the middle end of the right side of the shell and is fixedly connected with a screw rod. The left side of the outer surface of the screw rod is threadedly connected with a slider. The middle end of the lower surface of the slider is fixedly connected with an electric telescopic rod. The telescopic end of the electric telescopic rod is fixedly connected with a connecting head. The middle end of the lower surface of the connecting head is fixedly connected with a water outlet. The utility model is provided with an electric telescopic rod, a water pump, a servo motor and a sampling bottle, achieving the purpose of convenient sub-packaging, solving the problem that the existing water quality sampling device cannot quickly sub-package the sampled water at different positions into a container, resulting in difficult sub-packaging during its operation and affecting the sampling efficiency.

[0004] However, it still has the following disadvantages: The device moves the hose left and right by setting a servo motor to store different water qualities. However, water quality residues collected last time will remain on the inner wall of the water pump and the pipeline, causing the water quality collected next time to be polluted by the water quality of the previous time. For this reason, we propose a water quality sampling device for environmental detection to solve this problem. Content of the Utility Model
