Technical Field

[0001] The utility model relates to the technical field of groundwater level measuring devices, in particular to a groundwater level ruler applicable to various wellhead conditions. Background Technique

[0002] The groundwater level refers to the elevation of the groundwater surface relative to the reference plane, usually expressed in altitude elevation. It is an important parameter reflecting the recharge, runoff, and discharge conditions of groundwater and the availability of groundwater resources. It is also the true response of the groundwater system to changes in the external environment. Measuring the groundwater level is a direct means for people to obtain the groundwater level and its dynamic laws.

[0003] Measuring the groundwater level is one of the important tasks in groundwater level observation and management. Accurately measuring the groundwater level is crucial for the effective development and management of groundwater resources. The water level ruler is the most commonly used measuring tool in groundwater level measurement work. The currently commonly used water level rulers mostly have a fixed counterweight design. Limited by various on-site conditions such as well pipe diameter, downhole pump in the well, and pump pipe diameter, the measuring rope is often stuck by flanges and wires, unable to be lowered into the well or unable to be pulled out after being lowered into the well, seriously affecting the on-site work progress. At the same time, it often causes certain economic losses to the groundwater level comprehensive measurement work due to the measuring rope being pulled off. Therefore, a groundwater level ruler applicable to various wellhead conditions is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a groundwater level ruler applicable to various wellhead conditions, which has the advantages of convenient use, can be applicable to different wellhead conditions by replacing the counterweight block, and can effectively protect the measuring rope, and solves the problems of the existing groundwater level ruler that cannot replace the counterweight, has a high rate of being stuck and damaged, and takes a long time after the measuring rope is stuck when measuring the water level.

[0005] In order to achieve the above purpose, the present application adopts the following technical solution: A groundwater level ruler applicable to various wellhead conditions, including a bracket main body, a control panel is installed on one side of the bracket main body, a switch, an indicator light, a voltmeter, a buzzer, a battery compartment, and a handle are arranged on one side of the control panel, a water level ruler main body is wound on the surface of the bracket main body, an anti-false alarm device is installed at the other end of the water level ruler main body, a connecting ring is installed at the bottom of the anti-false alarm device, a connecting rope is fixed at the bottom of the connecting ring, a counterweight block is fixed at the bottom of the connecting rope, L-shaped plates are fixed on both sides of the anti-false alarm device, a limiting rod is slidably connected inside the L-shaped plate, limiting holes are opened on both sides of the anti-false alarm device, and the limiting rod passes through the inside of the connecting ring and is slidably connected with the limiting hole.

[0007] Preferably, a rotating rod is rotatably connected inside the L-shaped plate, and a limiting block is fixed to one end of the rotating rod.

[0008] Preferably, a storage box is installed on one side of the bracket main body, and a storage groove is opened on one side of the storage box.

[0012] The technical effects and advantages of the present utility model:

[0013] In the present utility model, by pulling the limiting rod outwards until the limiting rod disengages from the inside of the limiting hole, the fixing of the connecting ring is released, so that a counterweight device of different shapes can be selected according to the on-site wellhead conditions.

Detailed implementation manners

[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Refer to Figures 1-5As shown in the figure, the present utility model provides a technical solution: an underground water level gauge applicable to various wellhead conditions, including a support main body 1. A control panel 28 is installed on one side of the support main body 1. On one side of the control panel 28, there are a switch 2, an indicator light 3, a voltmeter 4, a buzzer 5, a battery compartment 6, and a handle 7. The surface of the support main body 1 is wound with a water level gauge main body 8. The other end of the water level gauge main body 8 is installed with an anti-false alarm device 9. A connecting ring 10 is installed at the bottom of the anti-false alarm device 9. A connecting rope 11 is fixed to the bottom of the connecting ring 10. A counterweight 12 is fixed to the bottom of the connecting rope 11. L-shaped plates 13 are fixed on both sides of the anti-false alarm device 9. A limiting rod 14 is slidably connected inside the L-shaped plate 13. Limiting holes 15 are opened on both sides of the anti-false alarm device 9. The limiting rod 14 passes through the inside of the connecting ring 10 and is slidably connected with the limiting hole 15. When measuring the underground water level in the wild, first turn on the switch 2. It is possible to judge whether the underground water level is reached through the voltmeter 4, the indicator light 3, and the buzzer 5. At the same time, the response degree of the voltmeter 4, the indicator light 3, and the buzzer 5 is controlled by the rotary switch 2. By pulling the limiting rod 14 outward until the limiting rod 14 disengages from the inside of the limiting hole 15, the fixing of the connecting ring 10 is released, so that it is possible to select and use counterweight devices of different shapes according to the on-site wellhead conditions. Even if the water level gauge main body 8 is stuck during on-site measurement, when the load-bearing threshold of the connecting ring 10 is exceeded, the water level gauge main body 8 can also be pulled out. Among them, the water level gauge main body 8 is a steel bendable straight ruler. By replacing the appropriate counterweight 12 on-site, the water level measurement work can be continued, effectively improving the actual work efficiency in the wild and reducing the work cost.

[0023] Referring to Figure 3 As shown in the figure, in this implementation: a limiting disc 16 is fixed on the surface of the limiting rod 14. A spring 17 is fixed on one side of the limiting disc 16. The other end of the spring 17 is fixed to the L-shaped plate 13. The surface of the limiting rod 14 is slidably connected with the spring 17. By setting the limiting disc 16, when the limiting rod 14 is pulled and needs to return to its original position, release the limiting rod 14, so that the spring 17 pushes the limiting disc 16 due to the restoration of the elastic force. At this time, the limiting disc 16 will drive the limiting rod 14 to insert into the inside of the limiting hole 15, playing a role in resetting the limiting rod 14, facilitating the operator to reuse it and being convenient to adjust.

[0024] Referring to Figure 3As shown, in this implementation: A rotating rod 18 is rotatably connected inside the L-shaped plate 13. One end of the rotating rod 18 is fixed with a limiting block 19. After the limiting rod 14 moves away from the inside of the limiting hole 15, rotate the rotating rod 18 to drive the limiting block 19 to block in front of the spring 17. Then release the limiting rod 14 so that the spring 17 drives the limiting disc 16 to contact the limiting block 19. At this time, the limiting block 19 will limit the limiting disc 16. When the limiting rod 14 needs to be inserted into the limiting hole 15, rotate the rotating rod 18 so that the limiting block 19 no longer blocks the limiting disc 16, and then the spring 17 will drive the limiting rod 14 to insert into the limiting hole 15.

[0025] Refer to Figure 4 As shown, in this implementation: A storage box 20 is installed on one side of the bracket main body 1. A storage groove 21 is opened on one side of the storage box 20. By installing the storage box 20, it is convenient to store the counterweight 12.

[0026] Refer to Figure 5 As shown, in this implementation: An anti-wear device 22 is movably installed on one side of the bracket main body 1. A bracket card slot 23 is opened on one side of the anti-wear device 22, and a wire groove 24 is opened on the other side of the anti-wear device 22. The anti-wear device 22 is made of ultra-high molecular weight wear-resistant polyethylene, and the overall shape is D-shaped. The bracket card slot 23 is used to store the anti-wear device 22 on the bracket main body 1. The bracket card slot 23 is used to clamp the anti-wear device 22 on the well wall when the well diameter is large. The water level gauge main body 8 is smoothly inserted into the well from the wire groove 24. The middle wire-passing hole 25 is used to measure small-diameter tube wells. When the anti-wear device 22 is placed at the wellhead, the water level gauge main body 8 passes through the wire-passing hole 25 to achieve the purpose of anti-wear. The anti-movement groove 26 is used to prevent the anti-wear device 22 from moving when measuring small-diameter tube wells. Multiple concentric anti-movement grooves 26 on the side can make the anti-wear device 22 be used for tube wells of various diameters, so as to realize the selection of the placement position of the anti-wear device 22 according to the diameter of the well wall pipe on site, effectively preventing and reducing the wear degree of the water level gauge main body 8.

[0027] Working principle: When the user measures the groundwater level in the wild, first turn on switch 2. Whether the groundwater level is reached can be judged through the voltmeter 4, the indicator light 3 and the buzzer 5. At the same time, the response degree of the voltmeter 4, the indicator light 3 and the buzzer 5 is controlled by the rotary switch 2. Pull the limit rod 14 outwards until the limit rod 14 disengages from the inside of the limit hole 15, releasing the fixation of the connecting ring 10, so as to realize the selection of counterweight devices of different shapes according to the wellhead conditions on site. Even if the water level gauge main body 8 is stuck during on-site measurement, when the load-bearing threshold of the connecting ring 10 is exceeded, the water level gauge main body 8 can also be pulled out. Among them, the water level gauge main body 8 is a steel bendable straight ruler. Replace the appropriate counterweight block 12 on site, and then the groundwater level measurement work can be continued, effectively improving the actual work efficiency in the wild and reducing the work cost. By setting the limit disc 16, when the limit rod 14 is pulled and needs to return to its original position, release the limit rod 14, so that the spring 17 pushes the limit disc 16 due to the restoration of the elastic force. At this time, the limit disc 16 will drive the limit rod 14 to insert into the inside of the limit hole 15, playing a role in resetting the limit rod 14, which is convenient for the operator to reuse and is easy to adjust. When the limit rod 14 is far away from the inside of the limit hole 15, rotate the rotating rod 18 to drive the limit block 19 to block in front of the spring 17, and then release the limit rod 14, so that the spring 17 drives the limit disc 16 to contact the limit block 19. At this time, the limit block 19 will limit the limit disc 16. When the limit rod 14 needs to be inserted into the limit hole 15, rotate the rotating rod 18 so that the limit block 19 no longer blocks the limit disc 16, and then the spring 17 will drive the limit rod 14 to insert into the limit hole 15. By installing the storage box 20, it is convenient to store the counterweight block 12. The anti-wear device 22 is made of ultra-high molecular weight wear-resistant polyethylene, and the overall shape is D-shaped. The bracket slot 23 is used to store the anti-wear device 22 on the bracket main body 1. The bracket slot 23 is used to clamp the anti-wear device 22 on the well wall when the well diameter is large. Slide the water level gauge main body 8 smoothly into the well from the wire groove 24. The middle wire-passing hole 25 is used to place the anti-wear device 22 at the wellhead when measuring small-diameter tube wells, so that the water level gauge main body 8 passes through the wire-passing hole 25 to achieve the purpose of anti-wear. The anti-movement groove 26 is used to prevent the anti-wear device 22 from moving when measuring small-diameter tube wells. Multiple concentric anti-movement grooves 26 on the side can make the anti-wear device 22 be used for tube wells of various diameters, so as to realize the selection of the placement position of the anti-wear device 22 according to the diameter of the well wall tube on site, effectively preventing and reducing the wear degree of the water level gauge main body 8.
