Description

Technical Field

[0001] This utility model relates to the technical field of water level measurement tools, and in particular to a tool for measuring water level in boreholes used in rock and soil exploration. Background Technology

[0002] Water level measurement tools are indispensable equipment in fields such as water conservancy engineering, environmental monitoring, and hydrological research. They can accurately measure the depth of water bodies and monitor changes in water levels, providing important data support for flood control, water resource management, and water quality monitoring. After geological drilling, it is usually necessary to use measurement tools to measure the water level inside the borehole.

[0003] Current water level measuring tools involve the operator slowly lowering a measuring rope with a float until the float touches the water surface. By observing the markings on the measuring rope, the operator can determine the height between the water surface and the ground. However, this method only reflects the height of the liquid surface relative to the ground and cannot directly provide specific depth information. Furthermore, when encountering gravity or the impact of water flow, the measuring rope may accidentally wind up or unwind, causing deviations in the scale readings. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the above-mentioned equipment has a small measurement range and low measurement accuracy due to relying solely on the release of the measuring rope. Therefore, this invention proposes a tool for measuring water level in boreholes for geotechnical exploration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tool for measuring water level in boreholes for geotechnical exploration, comprising a shell, two mounting holes I on the outer wall of the shell, two movable holes I on the outer wall of the shell, a motor fixedly mounted on one side of the outer wall of the shell, a worm gear fixedly mounted on the output end of the motor, and the inner surface of the two movable holes I being movably inserted into the outer surface of the worm gear; two movable holes II on the outer wall of the shell, a rotating shaft movably inserted between the inner surface of the two movable holes II, a worm wheel fixedly sleeved on the outer wall of the rotating shaft, and the outer surface of the worm wheel meshing with the inner surface of the worm gear; a take-up roller fixedly sleeved on the outer wall of the rotating shaft, and a measuring rope wound on the outer surface of the take-up roller.

[0006] Preferably, a counterweight is wound around the outer wall of the measuring rope, a resistance contact is provided at the bottom of the counterweight, and an echo sounder is fixedly installed at the bottom of the counterweight.

[0007] Preferably, a controller is provided on one side of the outer wall of the housing, and a handle is fixedly installed on the top of the housing.

[0008] Preferably, the top of the outer casing has a second mounting hole, and a rotation measuring instrument is fixedly inserted into the inner surface of the second mounting hole.

[0009] Preferably, a heating fan is fixedly inserted into the inner wall of each of the two mounting holes, and a guide frame is fixedly installed on one side of the inner wall of the outer shell, with the inner wall of the guide frame in contact with the outer wall of the measuring rope.

[0010] Preferably, the bottom of the outer casing is provided with a mounting hole three, and a set of fixing rods are fixedly installed between the inner surface walls of the mounting hole three.

[0011] Preferably, each of the outer walls of a set of fixed rods is movably fitted with a brush, and the outer walls of the set of brushes are in contact with each other.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the rotation of the worm gear and worm wheel driven by the motor drives the rotating shaft and the winding roller to rotate together, thereby realizing the precise release and retrieval of the measuring rope. This avoids accidental release or winding of the measuring rope due to manual operation or external interference, reducing measurement errors. When the resistance contact contacts the water surface, it can quickly transmit the current signal to the controller and cooperate with the rotation measurement instrument to obtain the distance between the water surface and the ground. The echo depth sounder is then activated to measure the water depth through sound waves, thus providing more comprehensive measurement data for the device.

[0014] 2. In this utility model, the brush can remove water droplets from the resistive contacts and the surface of the echo sounder, and then the heating fan can dry them with hot air, preventing electrical components from being damaged by moisture and extending the service life of the equipment.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4 As shown, this utility model provides a tool for measuring water level in boreholes for geotechnical exploration, including a housing 1. The outer wall of the housing 1 has two mounting holes 2 and two movable holes 3. A motor 4 is fixedly mounted on one side of the outer wall of the housing 1, and a worm gear 5 is fixedly mounted on the output end of the motor 4. The worm gear 5 is movably inserted between the inner surface of the two movable holes 3 and the outer surface of the worm gear 5. The outer wall of the housing 1 also has two movable holes 6, and a rotating shaft 7 is movably inserted between the inner surface of the two movable holes 6. A worm wheel 8 is fixedly sleeved on the outer surface of the rotating shaft 7. Furthermore, the outer wall of the worm gear 8 is meshed with the inner wall of the worm 5. The outer wall of the rotating shaft 7 is fixedly fitted with a take-up roller 9. The outer wall of the take-up roller 9 is wound with a measuring rope 10. The outer wall of the measuring rope 10 is wound with a counterweight 11. The bottom of the counterweight 11 is provided with a resistance contact 12. The bottom of the counterweight 11 is fixedly installed with an echo sounder 13. A controller 14 is provided on one side of the outer wall of the outer shell 1. A handle 15 is fixedly installed on the top of the outer shell 1. The top of the outer shell 1 is provided with a second mounting hole 16. A rotation measuring instrument 17 is fixedly inserted into the inner wall of the second mounting hole 16.

[0024] The overall effect of Embodiment 1 is as follows: when the measuring tool is needed, the user can start the motor 4, which drives the worm 5 to rotate inside the movable hole 3. The worm 5 then drives the worm wheel 8 to rotate together. The shaft 7 on the inner wall of the worm wheel 8 rotates inside the movable hole 6, driving the take-up roller 9 to rotate synchronously and lowering the measuring rope 10 wound on the outer wall. Because the worm wheel 8 and worm 5 have a self-locking property, it can effectively prevent the take-up roller 9 from rotating again due to external force when it is stationary, thus preventing the measuring rope 10 from moving uncontrollably and affecting the accuracy of the measurement results. When the resistance contact 12 contacts the water surface, it transmits a current signal to the controller 14. The rotation speed measuring instrument 17 on the top of the take-up roller 9 measures the rotation speed of the take-up roller 9 in real time through laser. The controller 14 is electrically connected via wires, enabling it to obtain the distance between the water surface and the ground in real time. The data is displayed on the screen on the controller 14. Subsequently, the echo sounder 13, submerged in the water, is activated. By emitting sound waves in the water, the sound waves are reflected when they encounter the bottom. The echo sounder 13 converts the received sound wave signal into an electrical signal and transmits it to the controller 14, which is electrically connected to it. The controller 14 processes the data to obtain the water depth data. This device can obtain the distance between the water surface and the ground and also measure the water depth, improving the comprehensiveness of the measurement data and making the measurement results more accurate. The rotation measuring instrument 17 allows people to obtain specific data without visually observing the measuring rope 10, improving work efficiency and avoiding errors caused by manual observation.

[0025] Example 2, as Figures 2-4 As shown, heating fans 18 are fixedly inserted into the inner walls of the two mounting holes 1 and 2. A guide frame 19 is fixedly installed on one side of the inner wall of the outer shell 1, and the inner wall of the guide frame 19 is in contact with the outer wall of the measuring rope 10. A mounting hole 3 and 20 are opened at the bottom of the outer shell 1. A set of fixing rods 21 are fixedly installed between the inner walls of the mounting hole 3 and 20. A brush 22 is movably sleeved on the outer wall of the set of fixing rods 21, and the outer walls of the set of brushes 22 are in contact with each other.

[0026] The effect achieved by the entire embodiment 2 is that after the measurement is completed, the counterweight 11 drives the resistance contact 12 and the echo sounder 13 to rise. When the wet resistance contact 12 and the echo sounder 13 come into contact with the two brushes 22, they will drive the two brushes 22 to rotate on the surface of the two fixed rods 21, brushing off the water droplets on their surface. At this time, the heating fan 18 starts, draws in the outside air, heats it, and blows it onto the surface of the resistance contact 12 and the echo sounder 13, effectively preventing the relevant electrical components from being damaged by moisture and extending the service life of the equipment. Excess air can be discharged through the mounting hole 3 20.

[0027] Working principle: When measurement is required, the operator can start motor 4, which drives worm 5 to rotate within movable hole 3. Worm 5 drives worm wheel 8 to rotate, and the shaft 7 on the inner wall of worm wheel 8 rotates accordingly. This causes take-up roller 9 to rotate synchronously, thereby releasing the measuring rope 10 wound on its outer wall. Due to the self-locking characteristic between worm wheel 8 and worm 5, this effectively prevents take-up roller 9 from rotating accidentally due to external force when stationary. When the resistance contact 12 at the end of the measuring rope 10 contacts the water surface, it transmits a current signal to controller 14. At the same time, the rotation speed measuring instrument 17 on the top of take-up roller 9 monitors the rotation speed of take-up roller 9 in real time through laser technology and is electrically connected to resistance contact 12 and controller 14 through wires. Controller 14 quickly calculates the water surface and the rotation speed. The distance to the ground is measured and displayed on its screen. Then, the echo sounder 13, submerged in water, emits sound waves in the water. These sound waves are reflected when they encounter the bottom of the water. The echo sounder 13 is responsible for receiving these reflected sound wave signals, converting them into electrical signals, and transmitting them to the controller 14. After the controller 14 processes these data, it can obtain the water depth data. After the measurement is completed, the counterweight 11 will drive the resistive contact 12 and the echo sounder 13 to rise. When the wet resistive contact 12 and the echo sounder 13 come into contact with the two brushes 22, the brushes 22 will rotate on the surface of the fixed rod 21 to brush away the water droplets on its surface. At this time, the heating fan 18 will start, draw in the outside air and heat it, and then blow the hot air onto the surface of the resistive contact 12 and the echo sounder 13.

[0028] The wiring diagrams for the motor 4, resistance contact 12, echo sounder 13, controller 14, speed measuring instrument 17, and heating fan 18 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the motor 4, resistance contact 12, echo sounder 13, controller 14, speed measuring instrument 17, and heating fan 18 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
