Description

Technical Field

[0001] The utility model relates to the technical field of groundwater wells, and specifically relates to a groundwater sampling device. Background Technique

[0002] Groundwater refers to the water stored in the rock voids below the ground surface. Narrowly speaking, it refers to the water in the saturated aquifer below the groundwater table; a well is mainly an engineering structure for extracting groundwater; it can be vertical, inclined, or a combination of different directions, but generally it is mainly vertical and can be used for domestic water intake and irrigation.

[0003] Irrigation is a technical measure to supplement the water required by crops; in order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply crops with sufficient water; under natural conditions, due to insufficient precipitation or uneven distribution, it often cannot meet the water requirements of crops; artificial irrigation must be carried out to make up for the deficiency of natural rainfall; well irrigation is a method of farmland irrigation, that is, using electromechanical equipment to pump water from wells to irrigate plants; well irrigation is suitable for northern regions with less precipitation. The advantage is that there is no need to build open channels, or it is impossible to obtain surface water resources and open channels cannot be built, so it occupies less cultivated land. The disadvantage is that excessive extraction of groundwater will cause ground subsidence. For example, a groundwater quality monitoring and sampling device with the application number CN202410120477.7 can collect groundwater samples and can make a preliminary judgment on the water quality to determine whether the water source can be used for agricultural irrigation. However, this groundwater quality monitoring and sampling device can only sample open wells and cannot sample wells. Content of the Utility Model

The retractable wheel structure facilitates the operator to lower and retract the sampling structure. By manually rotating the retractable wheel structure by the operator, the lowering speed of the sampling structure can be well guaranteed, so as to ensure the safe inspection and sampling work of the sampling structure.

[0025] Specifically, the guiding structure includes: a guiding frame 8 and a guiding wheel 9; The guiding frame 8 is installed on the side wall surface of the base 1, and the guiding wheel 9 is installed inside the guiding frame 8. The guiding structure facilitates the retractable wheel structure to explore the groundwater well, facilitates the retractable cable 6 of the retractable wheel structure to turn, and ensures that the retractable cable 6 can be lifted and lowered perpendicular to the ground.

[0026] Specifically, the sampling structure includes: a sampling container 10, a one-way valve 11, a connecting rod 12, a pressure sensor 13, a counterweight lead weight 14 and a liquid sensor 15; The sampling container 10 is installed at the tail of the retractable cable 6, the one-way valve 11 is installed on the side wall surface of the sampling container 10, the connecting rod 12 is installed on the lower wall surface of the sampling container 10, the pressure sensor 13 is installed on the lower wall surface of the connecting rod 12, the counterweight lead weight 14 is installed on the lower wall surface of the pressure sensor 13, and the liquid sensor 15 is installed on the lower wall surface of the counterweight lead weight 14. The sampling structure facilitates the collection of groundwater and can monitor the relevant data of the groundwater well, facilitating the operator to calculate how much agricultural land can be irrigated by this groundwater well.

[0027] Specifically, the monitoring structure includes: a monitoring seat 16, two lighting lamps 17 and a monitoring camera 18; The monitoring seat 16 is installed on the upper wall surface of the sampling container 10, the two lighting lamps 17 are installed on the lower wall surface of the monitoring seat 16, and the monitoring camera 18 is installed on the lower wall surface of the monitoring seat 16.

[0028] Working principle: When using the present utility model, the operator first connects an external AC power supply to the battery 22 to charge the battery 22. When the battery 22 is fully charged, the battery 22 can provide energy for the electrical appliances in the present utility model. The operator first moves the present utility model to the place where groundwater detection is required through two handling handles 19. The operator starts the present utility model and holds the retracting handle 7, so that one end of the counterweight lead 14 and the retracting cable 6 is put into the irrigation well. At this time, the operator continuously rotates the retracting handle 7, driving the retracting shaft 4 and the retracting roller 5 to rotate. The retracting cable 6 is continuously pulled by the gravity of the counterweight lead 14 and enters the water well. During the process of entering the water well, the operator can see the picture taken by the monitoring camera 18 through the display 20. The two lighting lamps 17 can illuminate the inside of the well passage, facilitating the operator to observe the inside of the well passage through the monitoring camera 18. When the liquid sensor 15 contacts water, the speaker 21 issues a voice reminder of "contacting the water source". When the sampling container 10 and the one-way valve 11 are completely immersed in water, the one-way valve 11 will be squeezed open by the water pressure. At this time, groundwater enters the inside of the sampling container 10. When the counterweight lead 14 continues to move down and contacts the bottom, the pressure sensor 13 will be subjected to pressure. At this time, the speaker 21 issues a voice reminder of "contacting the bottom surface". At this time, the operator performs the retracting work through the retracting handle 7 to lift out the sampling container 10. At this time, the sampling of agricultural groundwater and the detection of the situation of the groundwater well are completed, thus facilitating the irrigation work of agricultural staff.
