Description

Technical Field

[0001] The present invention relates to the field of hydraulic engineering and environmental protection, and relates to the direction of groundwater level measurement, specifically to a groundwater level data acquisition device and an acquisition method thereof. Background Art

[0002] A groundwater level meter is an instrument specifically designed to measure the elevation of the groundwater surface. It primarily consists of a reel, a measuring rope wrapped around the reel, and a probe connected to the starting end of the rope. To collect groundwater level data, the probe is lowered into the observation tube exposed above the ground. The reel is rotated continuously, allowing the rope to be released. The probe descends until its bottom touches the horizontal surface. The probe then beeps to alert the operator, who then stops rotating the reel and observes the scale on the upper end of the observation tube corresponding to the measuring rope. Groundwater level data is then collected.

[0003] However, there are still the following problems when collecting groundwater level data using groundwater level meters: 1. When encountering windy weather outdoors, the wind can easily blow the measuring rope and cause it to swing, which will swing the probe with it. Then the probe is likely to hit the wall during the downward movement, which can easily damage the probe and affect the collection of groundwater level data; 2. When the lower end of the probe touches the water surface and emits a beeping sound, the staff needs time to react before stopping the rotation of the reel. The measuring rope is often unwound for an extra length, thus affecting the accuracy of groundwater level data collection. 3. It is difficult for the staff to control the measuring rope to be perpendicular to the observation tube. The measuring rope is prone to tilt, and the actual length of the rope released will be greater than the vertical distance, which will also affect the accuracy of groundwater level data collection.

The touch switch 20 is located directly above the touch plate 22, and the touch switch 20 is electrically connected to the electric push rod 19.

[0024] The positioning mechanism includes a support plate 2, which is fitted on the upper end of the observation tube 5, and a slide groove 1 is symmetrically opened on the upper end of the support plate 2. Sliders 7 are slidably fitted in the two slide grooves 1. The side walls of the two slide blocks 7 that are away from each other are fixedly connected with guide columns 4. The two guide columns 4 are movable through the support plate 2. The two slide blocks 7 are respectively fixedly connected with first springs 9 between the two slide grooves 1. The two first springs 9 are respectively slidably mounted on the outer walls of the two guide columns 4. The lower ends of the two slide blocks 7 are fixedly connected with V-shaped plates 8. The inner V surfaces of the two V-shaped plates 8 are fitted with the outer wall of the observation tube 5. The support plate 2 is slidably mounted on the outer wall of the measuring rope 3.

[0025] Working principle: First, hold the probe body 23 and rotate the rotating sleeve 17 upward. The rotating sleeve 17 will rotate upward outside the stud 11, and the rotating sleeve 17 will also drive the ring 16 to slide upward outside the stud 11. The ring 16 will drive the multiple connecting rods 12 to rotate together. The multiple connecting rods 12 will drive the connected connecting plates 13 to rotate upward through their connected connecting blocks 18. The multiple connecting plates 13 will drive the connected guide wheels 14 to rotate together, until the probe body 23 is placed in the observation tube 5, and the multiple guide wheels 14 can fit exactly against the inner wall of the observation tube 5.

[0026] Then hold the pull rings outside the two V-shaped plates 8 with both hands (the pull rings can refer to Figure 2 ), and then move the two V-shaped plates 8 away from each other. Each V-shaped plate 8 will drive the slider 7 connected to it to slide in the corresponding slide groove 1 and squeeze the first spring 9, and each slider 7 will drive the guide column 4 connected to it to slide outward in the support plate 2. Then, the two V-shaped plates 8 are placed on both sides of the observation tube 5 and drive the support plate 2 to fit the upper end of the observation tube 5. Then, the pull rings outside the two V-shaped plates 8 are released. At this time, under the action of the first spring 9, the two V-shaped plates 8 can be automatically clamped outside the observation tube 5, and the centers of the support plate 2, the center of the observation tube 5 and the center of the probe body 23 are in a line. Finally, as shown in FIG. Figure 3 shown.

[0027] Then, the reel of the water level gauge body 6 is continuously rotated to continuously release the measuring rope 3. Under the action of gravity, the probe body 23 and the annular buoy 15 will continue to move downward, and the multiple guide wheels 14 will fit on the inner wall of the observation tube 5 and rotate counterclockwise downward continuously until the lower end face of the annular buoy 15 moves down to fit on the water surface. Because the lower end face of the annular buoy 15 is flush with the lower end face of the probe body 23, under the action of the annular buoy 15, the probe body 23 can always maintain contact with the water surface and will not move downward. At this time, the probe body 23 will emit a buzzing sound to let the staff know. At this time, the staff can stop rotating the reel of the water level gauge body 6, and the probe body 23 will be restricted by the multiple guide wheels 14 during the downward movement, and the wind will not blow the measuring rope 3, causing the probe body 23 to swing and hit the wall.

[0028] It should be noted that before the annular buoy 15 contacts the water surface, the hollow float 21 will first contact the water surface, and as the annular buoy 15 continues to move downward, the hollow float 21 will move up relative to the annular buoy 15. When the annular buoy 15 contacts the water surface, the touch plate 22 at the upper end of the hollow float 21 will move up to contact the touch switch 20, and the lower end surface of the hollow float 21 will be flush with the lower end surface of the annular buoy 15. Since the touch switch 20 is electrically connected to each electric push rod 19, each electric push rod 19 will drive the connecting frame 42, the splicing plate 43 and the multiple rubber blocks 29 to move toward the inner wall of the observation tube 5. The multiple rubber blocks 29 The rubber block 29 will squeeze the inner wall of the observation tube 5, and the splicing plate 43 will slide outside the corresponding multiple pillars 30 and squeeze the corresponding multiple second springs 28. Under the action of the multiple second springs 28 and the elasticity of the rubber block 29 itself, the multiple rubber blocks 29 can adapt to the curvature of the inner wall of the observation tube 5, and the multiple second springs 28 will also be squeezed to varying degrees, thereby increasing the contact area between the multiple rubber blocks 29 and the inner wall of the observation tube 5, thereby increasing the friction force. Then each electric push rod 19 will stop running, and under the friction force between the rubber block 29 and the inner wall of the observation tube 5, the probe body 23 can be fixed to a certain extent.

[0029] The measuring rope 3 can then be pulled upward to tighten the portion inside the observation tube 5. The probe body 23, which is fixed in place, will not move upward due to the pulling force. The portion of the measuring rope 3 inside the observation tube 5 can then be easily maintained in a vertical position. Since the measuring rope 3 passes through the center of the support plate 2, and the centers of the support plate 2, the observation tube 5, and the probe body 23 are aligned, the groundwater level data can be accurately obtained and collected by observing the scale on the upper end face of the observation tube 5 corresponding to the measuring rope 3. It is worth mentioning that, thanks to the annular buoy 15, workers do not need to spend time reacting to the beeping sound emitted by the probe body 23, as the lower end face of the probe body 23 can remain in contact with the water surface, thereby improving the accuracy of groundwater level data collection.

[0030] When the underground water level data is collected, the reel of the water level meter body 6 is turned back with force, and the measuring rope 3 will be continuously stored outside the reel, and the measuring rope 3 will drive the stud 11, the disc 25, the probe body 23 and the multiple guide wheels 14 to move upward. At this time, the multiple guide wheels 14 will rotate upward clockwise on the inner wall of the observation tube 5, and each guide wheel 14 will drive the respective connected rotating column 32 and the dial block 31 to rotate clockwise together, and each dial block 31 will rotate to squeeze the corresponding limit block 39, and each limit block 39 will drive the respective connected rotating plate 33 to rotate counterclockwise outside the corresponding support column 36, and each rotating plate 33 will twist the second torsion spring 37 connected to the corresponding fixed disk 38, and each The rotating plate 33 will drive the L-shaped block 34 to rotate counterclockwise away from the end face of the corresponding electric push rod 19. Since each tension spring 27 is in a stretched state, each electric push rod 19 will move close to its corresponding connecting block 18 under the action of the tension spring 27, and slide in its corresponding connecting block 18 with its connected connecting column 35. Then each electric push rod 19 will drive multiple rubber blocks 29 away from the inner wall of the observation tube 5, thereby quickly loosening the probe body 23. In summary, only a small section at the beginning requires force to turn the wire reel of the water level meter body 6, and subsequently you only need to lightly turn the wire reel to bring up the probe body 23. The probe body 23 can be automatically loosened inside the observation tube 5, which facilitates operation. It should be noted that as the probe body 23 subsequently moves upward and drives the multiple guide wheels 14 to continuously roll upward clockwise, each shift block 31 intermittently compresses the corresponding stop block 39, driving the corresponding rotating plate 33 to rotate outside the support column 36. Each rotating plate 33 also intermittently twists the second torsion spring 37. The elastic force of the second torsion spring 37 is very small, so it does not cause much resistance to movement. Finally, the two V-shaped plates 8 are pulled away from each other, driving the support plate 2 to separate from the observation tube 5.

[0031] It should also be noted that when the probe body 23 moves downward and drives the multiple guide wheels 14 to continuously roll downward counterclockwise, each shift block 31 will also touch the corresponding limit block 39, but on the contrary, each shift block 31 will drive the corresponding limit block 39 to rotate counterclockwise between the two U-shaped blocks 40, and each limit block 39 will drive the respective connected rotating shaft 41 to rotate, and each limit block 39 will twist the two first torsion springs 10 until each shift block 31 rotates away from the corresponding limit block 39. Under the action of the first torsion spring 10, each limit block 39 will reset and rotate and fit into the corresponding rotating plate 33, and continue to reciprocate. The elastic force of the first torsion spring 10 is slightly smaller than the elastic force of the second torsion spring 37, so it will not bring much movement resistance, and when the first torsion spring 10 twists, it will not transmit force to the second torsion spring 37 to rotate.

[0032] It should also be noted that the electric push rod 19 has its own external power supply, and the touch switch 20, the electric push rod 19 and the power supply are connected by a corresponding number of wires. When the touch switch 20 is touched by the touch plate 22, the conductive contacts inside the touch switch 20 are closed, so that the power supply, the touch switch 20 and the electric push rod 19 form a complete circuit. The DC power output by the power supply is transmitted to the electric push rod 19 through the wire, and the electric push rod 19 starts to operate. The telescopic shaft of the electric push rod 19 will extend. The electric push rod 19 has a built-in travel limit switch. When the telescopic shaft extends to the maximum travel, the travel limit switch is triggered and the motor power supply is cut off, thereby stopping the electric push rod 19. At this time, the multiple rubber blocks 29 connected to the electric push rod 19 will also be moved to the inner wall of the extrusion observation tube 5. The touch switch 20 and the electric push rod 19 are both well-known existing technologies, and the above-mentioned operation process is a conventional circuit design and will not be repeated.

[0033] It should also be noted that the distance from the upper end surface of the stud 11 to the lower end surface of the disc 25 is measured and calculated in advance. After obtaining the groundwater level data, the distance from the upper end surface of the stud 11 to the lower end surface of the disc 25 can be added.

[0034] It should also be noted that, due to the adjustability of the multiple guide wheels 14 , it can also adapt to the use of observation tubes 5 of different thicknesses.

[0035] The present invention also discloses a method for collecting groundwater level data, which comprises the following steps: S1: First, insert the probe body 23 into the observation tube 5, and use the adjustment mechanism to adjust the multiple guide wheels 14 outside the probe body 23 to fit the inner wall of the observation tube 5. At this time, hold the water level gauge body 6 to prevent the wire drum of the water level gauge body 6 from rotating and causing the measuring rope 3 to move; S2: Then, the center of the portion of the measuring rope 3 located inside the observation tube 5 can be aligned with the center of the observation tube 5 by means of the positioning mechanism; S3: The reel of the water level gauge body 6 is then rotated to continuously release the measuring rope 3. Under the action of gravity, the probe body 23 continuously moves downward in the observation tube 5 and rotates counterclockwise with the multiple guide wheels 14 attached to the inner wall of the observation tube 5 until it and the annular buoy 15 are attached to the groundwater surface. At this time, the probe body 23 is in contact with the water level and emits a buzzing sound. The probe body 23 can always remain above the water surface. S4: At the same time, through the cooperation between the trigger mechanism and the brake mechanism, the probe body 23 can be fixed on the water surface to a certain extent, and then the measuring rope 3 is gently pulled upward to keep it vertical. Then, the groundwater level can be accurately judged and collected by observing the scale on the upper end face of the observation tube 5 corresponding to the measuring rope 3. During the whole process, the probe body 23 will not hit the wall due to shaking.
