Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a groundwater level measurement device for geological exploration. Background Technology

[0002] Measuring the groundwater level is crucial in geological exploration, as it directly affects the physical and mechanical properties of the foundation soil. For example, when the groundwater level rises, the foundation soil softens, reducing its shear strength and thus decreasing the bearing capacity of the foundation. Conversely, when the groundwater level falls, the effective stress in the foundation soil increases, leading to consolidation settlement. Accurate measurement of the groundwater level is essential for the reasonable calculation of the foundation bearing capacity, providing a reliable basis for engineering foundation design and ensuring that buildings do not experience uneven settlement or tilting due to insufficient foundation bearing capacity.

[0003] A Chinese patent discloses a portable and simple groundwater level measuring device (publication number CN217403550U). This patented technology involves rotating a handle to lower a measuring tape. When the measuring bell touches the water surface, it makes a loud sound due to the special structure of the bell. The data marked on the measuring tape at this time is the groundwater level at that location. However, during measurement, one hand needs to hold the disc box and the other hand needs to hold the measuring rope spool and rotate it. After the data is measured, both hands are basically occupied during the operation and measurement process, making it difficult to free up hands to record the measurement data in time. Moreover, holding the measuring rope manually is easy to be unstable, which can easily lead to the measuring rope deviating. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A groundwater level measuring device for geological exploration, comprising:

[0006] The outer casing has support mechanisms on both sides near the bottom. A winding roller is rotatably connected inside the outer casing. A scale rope is wound around the outside of the winding roller. A measuring clock is connected to the end of the scale rope. A drive mechanism is provided on the outside of the outer casing.

[0007] A battery is connected to the left side of the casing.

[0008] In one possible implementation, the support mechanism includes a pair of second hinge seats, with a support arm rotatably connected inside the second hinge seats. A connecting rod is connected to the inner side of the support arm, and a first hinge seat is rotatably connected to the end of the support arm. A base plate is fixedly connected to the bottom of the first hinge seat, and four anchor piles are circumferentially connected through the inside of the base plate.

[0009] In one possible implementation, bearings are embedded in the middle of both sides of the housing, and a shaft is rotatably connected inside the bearing, with one end of the shaft fixedly connected to the winding roller.

[0010] In one possible implementation, the drive mechanism includes a servo motor, one side of which is fixedly connected to the housing. One end of the output shaft of the servo motor passes through the interior of the housing and is connected to a first pulley. A belt is fitted on the outer side of the first pulley, and a second pulley is connected to the inner side of the belt. The inner wall of the second pulley is fixedly connected to a shaft.

[0011] In one possible implementation, a placement box is connected to the right side of the housing, and a data recording board is connected inside the placement box.

[0012] In one possible implementation, a rotating sleeve is rotatably connected to the outer side of the connecting rod, and an LED light is fixedly connected to the outer side of the rotating sleeve.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By setting a pair of rotatable support arms on both sides of the outer casing and fixing the ends of the support arms with anchor piles, the outer casing can be easily fixed to the wellhead, thus ensuring that the scale rope is lowered vertically. This avoids the scale rope from shifting due to unstable hand grip, improving measurement accuracy. Then, the servo motor is turned on, driving the first pulley to rotate. Through the belt connection, the second pulley and the winding roller can be easily driven to rotate, controlling the vertical lowering of the scale rope. After contacting the water surface, the servo motor is turned off, and the measurement data can be recorded in time, freeing up the hand. This eliminates the need to hold the disc box with one hand and the measuring rope reel with the other hand to rotate and lower it. The measurement process is simple and efficient.

[0015] 2. By installing a rotatable LED light on the outside of the connecting rod, the LED light can illuminate the scale rope and the water surface in low-light environments, ensuring that the measuring personnel can accurately read the scale and observe the water surface conditions.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a groundwater level measurement device for geological exploration, thereby solving the problems in the prior art.

[0025] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0026] like Figures 1-4 As shown, a groundwater level measuring device for geological exploration includes:

[0027] The outer casing 1 has support mechanisms on both sides near the bottom. Inside the outer casing 1, a winding roller 21 is rotatably connected. A scale rope 9 is wound around the outside of the winding roller 21. The end of the scale rope 9 is connected to a measuring clock 10. A drive mechanism is provided on the outside of the outer casing 1. By setting up support mechanisms, it is easy to fix the outer casing 1 at the wellhead, thereby ensuring that the scale rope 9 is lowered vertically, avoiding the deviation of the scale rope 9 due to unstable hand holding, and improving the accuracy of measurement. By setting up drive mechanism, it is easy to free up hands to record measurement data in time, eliminating the need to hold the disc box with one hand and the measuring rope reel with the other hand to rotate and lower it.

[0028] A battery 15 is connected to the left side of the housing 1. By setting up the battery 15, it is beneficial to provide power support for the servo motor 14 and the LED light 5.

[0029] In some examples, the support mechanism includes a pair of second hinge seats 13, with a support arm 4 rotatably connected inside the second hinge seats 13. A connecting rod 12 is connected to the inner side of the support arm 4, and a first hinge seat 6 is rotatably connected to the end of the support arm 4. A base plate 8 is fixedly connected to the bottom of the first hinge seat 6, and four anchor piles 7 are circumferentially connected inside the base plate 8. By flipping the support arm 4, the base plate 8 rotatably connected to the end of the support arm 4 can be easily moved to a suitable position. Then, the end of the support arm 4 can be easily fixed by the anchor piles 7, which facilitates fixing the outer shell 1 to the wellhead, thereby ensuring that the scale rope 9 is lowered vertically and avoiding the deviation of the scale rope 9 due to unstable hand holding, thus improving the accuracy of measurement.

[0030] In some examples, bearings 16 are embedded in the middle of both sides of the housing 1. A shaft 17 is rotatably connected inside the bearing 16. One end of the shaft 17 is fixedly connected to the winding roller 21. The connection between the bearing 16 and the shaft 17 facilitates the rotation of the winding roller 21.

[0031] In some examples, the drive mechanism includes a servo motor 14, one side of which is fixedly connected to the housing 1. One end of the output shaft of the servo motor 14 passes through the interior of the housing 1 and is connected to a first pulley 18. A belt 19 is sleeved on the outside of the first pulley 18, and a second pulley 20 is connected to the inside of the belt 19. The inner wall of the second pulley 20 is fixedly connected to the shaft 17. When the servo motor 14 is turned on, the first pulley 18 is driven to rotate. Through the connection of the belt 19, the second pulley 20 and the winding roller 21 are easily driven to rotate, thereby controlling the vertical lowering of the scale rope 9.

[0032] In some examples, the right side of the outer casing 1 is connected to a placement box 3, and the inside of the placement box 3 is connected to a data recording board 2, so that people can take out the data recording board 2 to record data, and then put it back into the placement box 3 after recording.

[0033] In some examples, a rotating sleeve 11 is rotatably connected to the outside of the connecting rod 12, and an LED light 5 is fixedly connected to the outside of the rotating sleeve 11. In a dimly lit environment, the LED light 5 can illuminate the scale rope 9 and the water surface, ensuring that the measuring personnel can accurately read the scale and observe the water surface conditions.

[0034] This invention features a pair of rotatable support arms 4 on both sides of the outer casing 1, with anchor piles 7 for easy fixation of the ends of the support arms 4. This allows the outer casing 1 to be easily fixed at the wellhead, ensuring that the graduated rope 9 is lowered vertically. This prevents the graduated rope 9 from shifting due to unstable hand grip, thus improving measurement accuracy. Subsequently, the servo motor 14 is turned on, driving the first pulley 18 to rotate. Through the connection of the belt 19, the second pulley 20 and the winding roller 21 are easily driven to rotate, controlling the graduated rope 9 to be lowered vertically. After contacting the water surface, the servo motor 14 is turned off, allowing for immediate recording of measurement data. This eliminates the need to hold the disc box with one hand and the measuring rope reel with the other to rotate and lower it, making the measurement process simple and efficient.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
