[0002] Water resource monitoring is used by water service departments to monitor self-provided well water intake, monitor the water flow in and out of water plants, monitor open channel flow, monitor groundwater level, monitor water quality of water sources, and conduct remote water sales management of water resources, etc. It has played an important role in effectively protecting water resources, rationally using water resources, and strengthening the social awareness of water conservation. Through the monitoring of water resources, the dynamic changes of water quantity and quality can be understood in a timely manner, and their changing laws can be grasped, so as to provide a scientific basis for formulating water resource development, utilization, and protection plans. When extracting water samples, it is usually necessary to statically treat the obtained original water samples, and then extract the supernatant, and finally the required water samples can be obtained. When obtaining the supernatant, the staff can only use a water ladle to obtain the supernatant, but this method will cause the samples in the bucket to shake in the morning, resulting in the turbid liquid at the lower layer surging upward, causing secondary pollution of the supernatant. It is necessary to perform a static treatment again for each time the supernatant is obtained to ensure that the obtained water samples meet the requirements as much as possible. This not only has cumbersome procedures but also consumes time. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0026] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0027] Please refer to Figures 1 to 3, the present utility model provides a static separation device for water samples of new pollutants in environmental monitoring, including a base 01, a lifting assembly 02, and a drainage assembly 03; a sample collection bucket 04 is placed on the base 01. The lifting assembly 02 includes a telescopic column 21 and a support plate 22 provided on the telescopic column 21; the support plate 22 is arranged in parallel with the base 01, and an original sample bucket 05 is placed on the support plate 22. The telescopic column is longitudinally arranged on the base 01, and the telescopic column 21 can contract up and down in the longitudinal direction to adjust the height of the support plate 22. The drainage assembly 03 includes a hose 31 and a U-shaped tube 32; the inlet end of the U-shaped tube 32 is placed in the original sample bucket 05, and the outlet end is located outside the original sample bucket 05 and communicates with the inlet end of the hose 31. The outlet end of the hose 31 communicates with the sample collection bucket 04, and a water absorption air bag 33 is provided on the hose 31. When in use, by adjusting the height of the support plate 22, the original sample bucket 05 can be lifted to form a height difference between the original sample bucket 05 and the sample collection bucket 04; after the original sample bucket 05 has been statically settled, the staff can clamp the outlet end of the hose 31 and press the water absorption air bag 33, thereby forming a siphon effect, enabling the U-shaped tube 32 to suck the upper clear liquid in the original sample bucket 05 and discharge it into the sample collection bucket 04 through the hose 31, so that the upper clear liquid can be continuously extracted from the original sample bucket 05. During the entire extraction process, only one static settlement is required, and the lower turbid liquid will not surge during the extraction of the clear liquid, thus preventing the contamination of the upper clear liquid, shortening the sample extraction time, and greatly improving the sample acquisition efficiency.

[0028] In one embodiment, the sample collection bucket 04 and the original sample bucket 05 are not in a straight line in the longitudinal direction.

[0029] A through hole 221 is provided on the support plate 22, allowing the sample collection bucket 04 to pass through after the support plate 22 is lowered to the lowest point. When not in use, the length of the telescopic column 21 can be shortened to the shortest, at which time the support plate 22 is closest to the base 01, and the height of the entire device can be minimized for easy handling.

[0030] Please refer to Figure 4 , in one embodiment, a clamping mechanism 06 for clamping and fixing the original sample bucket 05 is provided on the support plate 22.

[0031] Specifically, the clamping mechanism 06 includes a first clamping portion 61 and a second clamping portion 62; the first clamping portion 61 is fixed on the support plate 22, and the second clamping portion 62 can move along the support plate 22 towards the first clamping portion 61 to clamp the original sample bucket 05 between the first clamping portion 61 and the second clamping portion 62.

[0032] Among them, to ensure the smooth sliding of the second clamping portion 62, a sliding groove 222 for the second clamping portion 62 to move is provided on the support plate 22.

[0033] Specifically, arc-shaped grooves 63 adapted to the shape of the original sample bucket 05 are provided on both the first clamping portion 61 and the second clamping portion 62. Thus, after the first clamping portion 61 and the second clamping portion 62 clamp the original sample bucket 05, the contact area and the degree of fit with the outer wall of the original sample bucket 05 can be increased to ensure the stability of clamping.

[0034] Specifically, mounting holes are provided on both sides of the first clamping portion 61, and springs 64 are arranged in the mounting holes. The other ends of the springs 64 are connected to the second clamping portion 62. When it is necessary to clamp and fix the original sample bucket 05, only need to pull the second clamping portion 62 outwards to increase the distance between the first clamping portion 61 and the second clamping portion 62, then the original sample bucket 05 can be placed between them, and then release the second clamping portion 62. Under the restoring force of the springs 64, the second clamping portion 62 will automatically slide towards the first clamping portion 61, and the clamping and fixing of the original sample bucket 05 can be quickly realized.

[0035] In an embodiment, a support column 07 is threadedly connected to the bottom of the base 01. When the ground is uneven, the height of the support column 07 can be adjusted to level the base 01.

[0036] In an embodiment, an annular groove 11 for placing the sample collection bucket 04 is provided on the base 01, and the annular groove 11 can be used to limit the lateral displacement of the sample collection bucket 04 and prevent the side shift of the sample collection bucket 04.

[0037] Please refer to Figure 5 , in an embodiment, a foam board 34 is provided at the inlet end of the U-shaped tube 32, and the inlet end of the U-shaped tube 32 passes through the foam board 34. When the inlet end of the U-shaped tube 32 is placed in the original sample bucket 05, the foam board 34 can float on the liquid surface, so that the inlet end of the U-shaped tube 32 is in the upper layer area of the liquid surface to facilitate obtaining the upper clear liquid. As the liquid surface gradually drops, the inlet end of the U-shaped tube 32 also drops synchronously with the liquid surface, and the continuous obtaining of the upper clear liquid can be realized.

[0038] In an embodiment, handles 08 are further provided on both sides of the base 01 for easy handling.

[0039] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
