[0039] Working principle:

[0040] like Figure 1-Figure 6 As shown, when the above-mentioned water quality sampler is in use, when water quality sampling is required, the motor 9 is started, and the rotating rod 6 connected to its output shaft rotates and starts to rotate, and the first bevel gear 7 on the rotating rod 6 rotates accordingly, and the rotating rod 6 drives the eccentric wheel 14 to rotate, and the eccentric wheel 14 contacts with the bottom of the pressure plate 13 to produce an up and down reciprocating motion, and this motion is transmitted to the piston 11 through the connecting rod 12, driving the piston 11 to move up and down in the sliding groove 10, thereby compressing the water sample in the sampler body 1, and the water sample flows into the sampler body 1 from the water inlet pipe 21, passes through the filter plate 2, and filters out large particles of impurities. The filtered water sample enters the sliding groove 10. During the compression process, the water sample is discharged through the water outlet pipe 22 until it is stored in the storage bottle 20. As the rotating rod 6 rotates, the first bevel gear 7 drives the second bevel gear 8 meshing with it to rotate, thereby prompting the light rod 3 and the cleaning brush 4 fixedly connected to the bottom of the light rod 3 to rotate. When the filter plate 2 rotates, the filter plate 2 is cleaned to remove impurities that may block the pores of the filter plate 2, thereby ensuring a smooth filtering process. As the connecting rod 12 moves up and down, the sliding plate 16 also slides up and down in the transmission groove 15. The spring 17 provides a buffer and a restoring force for this process, thereby ensuring that the mechanical movement is stable and reliably restored to the initial state, in preparation for the next sampling. The one-way valve 23 installed inside the water inlet pipe 21 and the water outlet pipe 22 ensures that the water sample can only flow in one direction, preventing the water sample from flowing back, thereby ensuring the purity of the collected sample. The water sample discharged through the water outlet pipe 22 is finally collected in the storage bottle 20, completing the sample collection and storage process. The handle 24 on the top of the sampler is convenient for the operator to carry and operate the sampler for on-site water quality sampling. Cleaning the filter plate 2 can prevent the sampling efficiency from being reduced due to blockage, thereby ensuring that the sampler always maintains the best performance and effectively completes the sampling operation, thereby greatly improving the operation quality and use efficiency compared with traditional devices.

[0041] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the utility model.
