Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, in particular to a continuous sampling method for water environment management. Background Art

[0002] The water environment refers to the spatial context within which water is formed, distributed, and transformed in nature. It encompasses the natural and social factors that contribute to the normal functioning of water bodies surrounding human populations and that directly or indirectly influence human life and development. Some also refer to the spatial context within which relatively stable, land-bound natural water bodies reside.

[0003] Water environment monitoring is water quality testing. The most basic work is water sampling. The water quality can be tested by obtaining the water quality at the sampling point through online or laboratory testing equipment. At present, sampling is mostly carried out by manual sampling, but this is not convenient for simultaneous sampling at multiple points in the same period, and it is also difficult to achieve single-point synchronous multi-depth sampling. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a continuous sampling method for water environment management with a high degree of automation and synchronous sampling.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A continuous sampling method for water environment management comprises the following steps: S1: planning at least two sampling points; S2: selecting a water sampling device with sampling sections of different depths according to sampling requirements; S3: synchronously performing interval continuous sampling at multiple points, or synchronously performing single sampling of water sources of different depths at multiple points; S4: online detection of water quality data, and transmitting the data back to a center; S5: performing backwashing self-cleaning at the sampling points, and waiting for the next sampling instruction.

[0007] As an optimization, in step S2, the sampling device is installed on an unmanned boat via a lifting cylinder, and the unmanned boat is fixed at the sampling point via an anchor body.

[0008] As an optimization, in step S2, the sampling sections at different depths are multiple vertically connected single sampling components, and the height between each single sampling component depends on a predetermined depth difference setting.

[0009] As an optimization, the single sampling assembly includes a sampling barrel, the sampling barrel is symmetrically provided with openings, the opening is provided with an opening and closing door, the opening and closing door is opened and closed by a cylinder, a water quality detector is provided in the sampling barrel, and the water quality detector is connected to the controller on the unmanned ship through a transmission line.

[0010] As an optimization, in step S4, the data is transmitted back to the center through the wireless transmission module of the controller for signal transmission.

[0011] As an optimization, in step S5, backwashing is performed through a water pipe provided in the sampling cylinder. The water pipe is provided with an electromagnetic valve corresponding to the sampling cylinder. After the detection is completed, the entire device rises above the liquid level, the water pipe flushes the backwash water into the sampling cylinder, the opening and closing door opens, the water sample inside is discharged, and the interior is cleaned.

[0012] As an optimization, in step S3, the step of performing interval continuous sampling on multiple points is to synchronously raise and lower the sampling device to sample the lower-end sampling component. After the interval time, the above actions are completed from bottom to top, and finally rise out of the water to complete the detection, transmission and flushing actions.

[0013] As an optimization, in step S3, the step of synchronously sampling water sources at different depths at multiple points is to simultaneously immerse the sampling devices at multiple points in water, open the opening and closing doors at the same time, complete the synchronous sampling of the sampling units at the same depth, and finally extend them out of the water to perform detection, transmission and flushing actions.

[0014] The present invention has the following advantages:

[0015] This solution can complete simultaneous continuous sampling at multiple points, or simultaneous single sampling of water sources at different depths at multiple points. Compared with the current manual sampling, it is more efficient and can meet the effect of simultaneous sampling, ensuring the reliability of the data. BRIEF DESCRIPTION OF THE DRAWINGS
