[0015] A sampling and detection assembly is connected to the lower end of a cable. The sampling and detection assembly includes a sampling section, a detection section, and a communication section. The sampling section is a cylindrical tube with a circumferential through hole on its outer peripheral wall. The detection section is located below the sampling section and contains a detection module. The communication section is located above the sampling section.

[0016] It also includes a damper connected to the cable and located above the sampling and detection assembly; the damper is bidirectional damping to control the moving speed of the sampling and detection assembly.

[0017] In some embodiments, the bottom surface of the sampling unit is provided with a vertical through hole, which is connected to the detection unit; groundwater enters the sampling unit through the circumferential through hole and then enters the detection unit through the vertical through hole.

[0018] In some embodiments, the detection unit is internally configured with at least one detection module, which is a temperature detection module and a pH value detection module.

[0019] In some embodiments, the lower part of the sampling and detection component is further provided with a tapered portion, which is disposed below the detection portion.

[0021] In some embodiments, the damper includes a damping housing, a damping oil storage chamber, a piston chamber, a solenoid valve, and a speed sensor. The damping oil storage chamber is located at the upper part of the damping housing and is connected to the piston chamber located in the middle of the damping housing via a pipeline. The solenoid valve is disposed on the pipeline. The piston is disposed inside the damping housing via the piston chamber. Connecting rods are disposed at both ends of the piston, and springs are disposed on the outer periphery of the connecting rods.

[0055] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0056] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0057] The accompanying drawings in this specification are schematic diagrams to aid in illustrating the concept of the invention, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0058] A schematic diagram of the structure of a portable integrated groundwater sampling and testing device described in this application is shown below. Figure 1 and Figure 2 As shown, it includes:

[0059] Fixture 10;

[0060] A drive assembly 20 is disposed between the side blocks 11 of the fixed frame 10; the drive assembly 20 includes a drive motor 21 and a drum 22, the drive motor 21 is an external rotor hub motor, the external rotor of which is connected to the drum 22, and a cable 23 is wound around the outside of the drum 22.

[0061] A sampling and detection component 30 is connected to the lower end of cable 23. The sampling and detection component 30 includes a sampling unit 31, a detection unit 32, and a communication unit 33, as shown below. Figure 5 As shown, the sampling part 31 is a cylindrical tube with a circumferential through hole 31a on its outer peripheral wall. The detection part 32 is located below the sampling part 31 and has a detection module inside. The communication part 33 is located above the sampling part 31. The communication part 33 is also equipped with a wireless transmission module to transmit the detection results in the detection part 32 to the ground wirelessly.

[0062] Furthermore, the portable groundwater sampling and testing integrated equipment also includes a damper 40, which is connected to the cable 23 and located above the sampling and testing component 30; the damper 40 is a bidirectional damper to control the moving speed of the sampling and testing component 30 and prevent the sampling and testing component 30 from moving too fast and affecting the accuracy of the sampling and testing.

[0063] The bottom surface of the sampling unit 31 is provided with a vertical through hole 31b, which is connected to the detection unit 32. Groundwater enters the sampling unit 31 through the circumferential through hole 31a and then enters the detection unit 32 through the vertical through hole 31b.

[0064] As an embodiment of the present invention, the detection unit 32 is internally configured with at least one detection module, which is a temperature detection module and a pH value detection module, to complete the detection of basic groundwater data.

[0065] Figure 7 This is a schematic diagram of another embodiment of the sampling and detection component of the present invention. The lower part of the sampling and detection component 30 is further provided with a conical part 34. The conical part 34 is disposed below the detection part 32 to reduce the resistance during the sinking process of the sampling and detection component 30 and control the descent speed of the sampling and detection component 30.

[0066] Furthermore, the sampling unit 31 is made of high molecular weight polypropylene, and its interior is equipped with a wave deflector 31c, such as... Figure 6 As shown, the wave deflector 31c is arranged along the length of the sampling section 31. It is understood that the sampling section 31 can also be made of polytetrafluoroethylene (PTFE). PTFE has good stability under normal conditions, generally does not react with other materials, is sturdy and durable, and has a certain degree of impact resistance.

[0067] Figure 6 In the illustrated embodiment, the number of wave-breaking plates 31c is one pair, which are symmetrically distributed with the center of the sampling section 31 as the base point. The spacing between adjacent wave-breaking plates 31c is 50-150mm. Figure 6In the design, the transverse cross-sectional shape of the wave-breaking plate 31c is rectangular. It is understandable that the transverse cross-sectional shape of the wave-breaking plate 31c could also be a closed curved surface to reduce disturbance to the groundwater sample.

[0068] In some embodiments, the wave deflector 31c is provided with transverse through-holes to effectively prevent the water sample from swaying during its ascent, thereby effectively reducing water sample disturbance and ensuring the accuracy of the test.

[0069] Figure 8 This is a schematic diagram of a damper provided in an embodiment of the present invention. The damper 40 includes a damping housing 41, a damping oil storage chamber 42, a piston 43 and a piston chamber 46, a solenoid valve 47, and a speed sensor 48. The damping oil storage chamber 42 is disposed on the upper part of the damping housing 41 and is connected to the piston chamber 46 located in the middle of the damping housing 41 through a pipeline. The solenoid valve 47 is disposed on the pipeline. The piston 43 is disposed inside the damping housing 41 via the piston chamber 46. Connecting rods 44 are disposed at both ends of the piston 43, and springs 45 are disposed on the outer periphery of the connecting rods 44. The springs 45 abut against the piston 43 and the inner wall of the damping housing 41. The speed sensor 48 is disposed inside the damping housing 41.

[0070] Figure 1 In the illustrated embodiment, the connecting rod 44 on the upper side of the damper 40 is fixed to the cable 23, and the connecting rod 44 on the lower side of the damper 40 is fixed to the communication section 33 on the upper side of the sampling and detection assembly 30. When the speed sensor 48 inside the damping housing 41 detects a decrease in the speed of the damper 40, the solenoid valve 47 located between the damping oil storage chamber 42 and the piston chamber 46 opens, and the damping oil in the damping oil storage chamber 42 flows through the pipeline to the piston chamber 46 and fills it. Figure 9 As shown. The frictional resistance between the damping oil in the piston chamber 46 and the outer peripheral wall of the piston 43 can slow down the movement speed of the piston 43; at the same time, the spring 45 on the outer peripheral side of the connecting rod 44 can also slow down the movement speed of the piston 43, thereby controlling the movement speed of the damper 40, so as to slow down the movement speed of the sampling and detection component 30 connected to the damper 40, until the damper 40 reduces the movement speed of the sampling and detection component 30 connected to the cable 23 to zero, so as to avoid the sampling and detection component 30 stopping too quickly and affecting the accuracy of the detection of various groundwater parameters.

[0071] Understandably, the damper 40 contains a microcontroller and power supply to detect its speed and control the opening of the solenoid valve 47. After the damper 40 has been used, it can be inverted and the solenoid valve 47 opened, allowing the damping oil to flow back from the piston chamber 46 to the damping oil storage chamber 42 for the next use.

[0072] Figure 1 In the illustrated embodiment, the mounting frame 10 includes a support leg 12, which is hinged to the side rail 11. The support leg 12 is a telescopic support leg, embedded in the bottom of the side rail 11; when needed, it can be extended laterally towards the input direction of the sampling and detection component 30, with an extension angle of 0-180°. The support leg 12 can adapt to unfavorable terrain such as undulations and slopes, effectively securing the portable integrated groundwater sampling and detection equipment; throughout the sampling process, no manual assistance is required for the equipment.

[0073] This equipment features a foldable outrigger design, which greatly enhances its stability during sampling. Simultaneously, the sampling and detection components 30 maintain a relatively constant speed during sampling, requiring minimal human intervention. Therefore, the equipment's stability is significantly improved, eliminating the need for additional sampling personnel to support it, effectively increasing work efficiency, and ensuring the safety of both personnel and equipment.

[0074] Furthermore, a roller assembly 13 is disposed at the lower part of the side guard 11, and the roller assembly 13 is hinged to the side guard 11; a return spring 14 is disposed between the roller assembly 13 and the side guard 11. The return spring 14 has a buffering effect, which can appropriately reduce shock when the equipment moves, so as to protect the electronic components of the equipment.

[0075] Furthermore, the mounting bracket 10 also includes a telescopic handle 15, which is located on the upper part of the side guard 11 to facilitate the use of the telescopic handle 15 and the roller assembly 13 to assist the sampling personnel in moving the portable integrated groundwater sampling and testing equipment.

[0076] In this invention, the portable groundwater sampling and detection integrated equipment also includes a manual component 50, which comprises a moving gear 51 and a hand crank 52, such as... Figure 3 As shown, the hand crank 52 is connected to the moving gear 51; the outer peripheral wall of the rotor of the drive motor 21 is provided with an external gear 21a, and the moving gear 51 can mesh with the external gear 21a.

[0077] It should be noted that the manual component 50 can move along the length of the hand crank 52 to control whether the moving gear 51 engages with the external gear 21a. When the manual component is needed to drive the drum 22 to rotate, the hand crank 52 needs to be moved forward so that the moving gear 51 is at least partially on the same horizontal plane as the external gear 21a, and the moving gear 51 engages with the external gear 21a. The operator rotates the hand crank 52 to drive the external gear 21a to rotate, which in turn drives the drum 22 to rotate, thereby adjusting the cable 23 wound on the drum 22 and adjusting the vertical position of the sampling and detection component 30.

[0078] When the drum 22 needs to be rotated electrically, simply move the hand crank 52 of the manual component 50 toward the operating surface, causing the moving gear 51 to disengage from the external gear 21a. Under the action of the drive motor 21, the drum 22 rotates, driving the cable 23 on it and the sampling and detection component 30 on it to move.

[0079] Existing sampling equipment cannot switch between manual and automatic modes; however, in this invention, due to the above-mentioned structure, the switch between manual and automatic modes can be achieved simply by the operator moving the hand crank 52, which effectively improves the convenience of the operation.

[0080] Figure 4 In this design, the drive motor 21 includes an external gear 21a, which is located outside the outer rotor and is a housing structure. The outer periphery of the housing structure has external teeth, and its inner periphery has internal teeth. Inside the external gear 21a are three evenly distributed internal gears 21b, and a motor rotating shaft gear 21c passes through the center of the external gear 21a. The motor rotating shaft gear 21c meshes with the internal gears 21b, and the teeth of the internal gears 21b mesh with the internal teeth of the external gear 21a. When the motor rotating shaft gear 21c of the drive motor 21 rotates, it drives the external gear 21a to rotate via gear transmission, thereby driving the drum 22 connected to the external rotor to rotate. This adjusts the position of the lower end of the cable 23 wound on the drum 22, thus achieving position adjustment of the sampling and detection component 30.

[0081] As an embodiment of the present invention, the portable integrated groundwater sampling and detection equipment is also equipped with a power supply to provide electrical energy for the operation of the drive motor 21. In some embodiments, the power supply is a battery, such as a 50000mAh rechargeable lithium battery. The battery is detachably mounted on the side plate 11 of the mounting bracket 10 and is connected to the drive motor 21 via a power cable. It is understood that the portable integrated groundwater sampling and detection equipment of the present invention can also use an external AC power supply, such as municipal power, to provide electrical energy for the operation of the drive motor 21.

[0082] Meanwhile, the portable integrated groundwater sampling and testing equipment of the present invention also includes a control device, which includes a depth controller. The depth controller is disposed in the drum 22 of the drive assembly. By controlling the rotation direction and number of turns of the drum 22, the depth of the cable 23 is controlled. Simultaneously, the control device is connected to a damper 40 to detect the moving speed of the sampling and testing component 30. When the speed of the damper 40 begins to decrease, the solenoid valve 47 of the damper 40 opens, filling the piston chamber 46 with damping oil to reduce the moving speed of the damper 40 and its connected sampling and testing component 30 until the moving speed of the sampling and testing component 30 reaches zero. This prevents the sampling and testing component 30 from moving too fast or stopping abruptly, which could affect the accuracy of groundwater parameter detection. Specifically, the sampling and testing component 30 moves upward or downward at a speed of 20 cm / s. If the moving speed of the sampling and testing component 30 decreases by 20% or more, it is inferred that the sampling and testing component 30 has begun to decelerate.

[0083] In this invention, the downward depth of the sampling and detection component 30 can be indirectly calculated by the number of rotations of the drum 22, and the number of rotations of the drum 22 can be comprehensively determined based on the depth at which the speed of the damper 40 decreases to zero consumption, so that the sampling and detection component 30 accurately reaches the set depth.

[0084] In this invention, the cable 23 is made of high molecular weight polypropylene, which has good lightweight, wear resistance and tensile strength. The cable 23 is engraved with depth marks and can move up and down within a depth range of 100-300m.

[0085] In some embodiments, the portable groundwater sampling and testing integrated equipment also includes a test result display mounted on the mounting frame 10 to display the groundwater sampling and testing results in real time. Furthermore, the test result display is signal-connected to a control device, which adjusts and controls the display of the test results.

[0086] Furthermore, this invention also provides a method for using a portable integrated groundwater sampling and detection device, which performs real-time detection using the aforementioned portable integrated groundwater sampling and detection device. The flowchart is as follows: Figure 10 As shown, it includes the following steps:

[0087] S1, the fixing frame 10 is set at a predetermined sampling point;

[0088] S2, install the sampling and detection component 30 on the cable 23 of the drive component 20, and set a damper 40 on the cable 23 above the sampling and detection component 30;

[0089] S3, the sampling and detection component 30 is lowered into the monitoring well by the drive component 20, and the drive component 20 sinks to a preset depth at a constant speed;

[0090] S4, the sampling and detection component 30 collects groundwater samples and performs real-time detection and analysis, and uploads the analysis results to the ground;

[0091] S5, after sampling is completed, the drive component 20 lifts the sampling and detection component 30 at a constant speed and transfers the groundwater from the detection unit 32 to the sample detection bottle.

[0092] This invention is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
