Description

Technical Field

[0001] The present application relates to the technical field of soil and water conservation, and in particular to a water conservancy project sampling device. Background Art

[0002] Water conservancy and soil and water conservation projects are important measures to ensure the sustainable use of water resources, prevent soil erosion, and maintain ecological environmental stability. In this process, sampling and analysis of environmental parameters such as soil and water quality is a crucial link, which can provide accurate data support for project design and implementation.

[0003] The sampling devices currently used in water conservancy and soil and water conservation projects can usually only sample at a single depth or location.

In addition, these devices also have deficiencies in sampling accuracy, which limits the comprehensiveness and representativeness of the sampling results, and thus produces inevitable errors. These errors may have an adverse impact on subsequent water quality analysis and governance decisions, and may even lead to decision-making errors. Utility Model Content

The positioning sensor allows the operator to know the position of the sampling device in real time. The control module 7 is responsible for receiving and processing various sensor signals and controlling the operation of components such as the servo motor 301 and the water pump 404 through the control module 7. During the sampling process, the controller controls the servo motor 301 to drive the winding roller 304 in the winding mechanism 3 to rotate according to the preset sampling depth and position information, thereby controlling the pay-out length of the sampling hose 407. When the sampling hose 407 reaches the preset depth, the controller starts the water pump 404 to draw the water sample into the sampling tube 402 through the sampling water pipe 403. At the same time, the depth sensor 409 monitors the actual sampling depth in real time and transmits the data to the control module 7 for recording and analysis. After sampling is completed, the controller controls the servo motor 301 to reverse, retract the sampling hose 407, and remove the sampling tube 402 from the storage tank 401. The water sample in the sampling tube 402 can be used for subsequent water quality analysis and evaluation.
