Therefore, an instrument capable of rapid calibration has emerged, bearing the heavy responsibility of ensuring accurate and reliable water level data and becoming an indispensable key support in the field of water resource management.

[0003] Most water level probe calibration instruments are based on simple comparative measurements. For example, a standard container with a known accurate water level is placed side by side with the container to be calibrated, and the difference between the measured value of the probe in the container to be calibrated and the water level in the standard container is observed. The probe scale is then manually adjusted or corrected using a simple mechanical device.

[0004] In existing technologies, some calibration devices are mainly composed of complex mechanical structures. During the process of achieving smooth and accurate raising and lowering of the scale bar, they are prone to jamming and shaking. This not only affects the calibration speed but also damages the stability of the measurement system, resulting in a significant reduction in the reliability of the calibration data. To address this issue, a rapid calibration instrument for water level detection rods is proposed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a water level detection rod rapid calibration instrument, including a protective shell 1. The protective shell 1 has a pushing mechanism inside and a fixing mechanism outside. A detection component for detection is fixedly connected to the outside of the protective shell 1. The protective shell 1 is used to provide a basic guarantee for the stable operation of the instrument.

[0025] The driving component includes a motor 8, which is externally fixedly connected to the inside of the protective shell 1. A drive wheel 9 is fixedly connected to the drive end of the motor 8, and the motor 8 drives the drive wheel 9 to rotate. A connecting shaft 12 is rotatably connected inside the protective shell 1, and a transmission component is fixedly connected to the outside of the connecting shaft 12. The connecting shaft 12 provides stable support for the driven wheel 10 and the transmission wheel 11. A sliding scale bar 2 is slidably connected to the outside of the transmission component. The sliding scale bar 2 drives the detection needle 4 to move up and down as it rises and falls. The transmission component includes a driven wheel 10. The drive wheel 9 drives the driven wheel 10 to rotate by its own rotation. The driven wheel 10 is internally fixedly connected to the outside of the connecting shaft 12, and the outside of the driven wheel 10 and the outside of the drive wheel 9 are meshed together. The driven wheel 10 receives the power of the drive wheel 9 and transmits it to the connecting shaft 12 through the meshing connection with the drive wheel 9, ensuring a smooth power transmission path and ensuring that subsequent components operate according to a predetermined trajectory.

[0026] Reference Figures 1 to 3 The fixing mechanism includes a base plate 7, which is externally fixed to the outside of the protective shell 1. A suction cup 17 is fixedly connected to the bottom of the base plate 7. The base plate 7 supports the suction pump 6. A toothed groove 3 is provided on the outside of the sliding scale bar 2. The suction pump 6 is used to evacuate the air inside the suction cup 17 to provide suction force for the suction cup 17, enabling rapid fixation of the instrument. A transmission wheel 11 is fixedly connected to the outside of the connecting shaft 12. The transmission wheel 11 is externally engaged with the inside of the toothed groove 3. The suction pump 6 is fixedly connected to the top of the base plate 7. A connecting pipe 18 is fixedly connected to the output end of the suction pump 6. A flexible fixing block 14 is slidably connected to the outside of the sliding scale bar 2. A limiting spring 13 is used to assist the flexible fixing block 14 in limiting and buffering the sliding scale bar 2 using its own elastic properties. The flexible fixing block 14 is used to provide a certain limit through the spring force during the movement of the sliding scale bar 2, preventing excessive displacement of the scale bar. A limiting spring 13 is fixedly connected to the protective shell 1. The external part of the limiting spring 13 is fixedly connected to the inside of the protective shell 1. The external part of the connecting pipe 18 is fixedly connected to the inside of the placement base plate 7. The connecting pipe 18 is used as an air transmission channel between the air pump 6 and the suction cup 17. The bottom of the connecting pipe 18 is fixedly connected to the top of the suction cup 17. The detection component includes a display screen 16. The display screen 16 is used to intuitively display the water level information transmitted from the detection processing block 15. The connecting pipe 18 is used to create a suitable temperature environment for electronic components, reduce the risk of failure, and ensure stable operation of the instrument. The external part of the display screen 16 is fixedly connected to the outside of the protective shell 1. A heat dissipation vent 5 is opened inside the protective shell 1. A detection needle 4 is slidably connected to the bottom of the sliding scale bar 2. The detection processing block 15 is fixedly connected inside the protective shell 1. The detection needle 4 is used to transmit the water level information to the detection processing block 15. The detection processing block 15 is used to quickly analyze and process the information using a built-in algorithm and convert it into a format that can be displayed on the display screen 16.

[0027] Working principle: The operator places the water level probe rapid calibration instrument in a suitable position where the water level probe needs to be calibrated. The suction cup 17 at the bottom of the base plate 7 contacts the placement surface. The suction pump 6 at the top of the base plate 7 extracts the air from the suction cup 17 through the connecting pipe 18, creating a negative pressure inside the suction cup 17, which then firmly adheres to the placement surface, fixing the instrument securely and preventing it from moving during subsequent calibration processes and affecting the calibration results.

[0028] After the instrument is fixed, the motor 8 drives the drive wheel 9 to rotate. The drive wheel 9 meshes with the driven wheel 10. The rotation of the drive wheel 9 will drive the driven wheel 10 to rotate, so the connecting shaft 12 will also rotate. The transmission wheel 11 outside the connecting shaft 12 will also rotate. The transmission wheel 11 meshes with the rack groove 3 on the outside of the sliding scale bar 2. In this way, the rotation of the transmission wheel 11 will be converted into the linear motion of the sliding scale bar 2, realizing the raising and lowering of the sliding scale bar 2. During the sliding process of the sliding scale bar 2, the flexible fixing block 14 on its outer side plays a certain limiting and buffering role under the action of the limiting spring 13, ensuring that the sliding scale bar 2 moves smoothly.

[0029] The bottom of the sliding scale bar 2 is slidably connected to the detection needle 4. As the sliding scale bar 2 rises and falls, the detection needle 4 can be replaced. When the detection needle 4 contacts the water level, the detection processing block 15 connected to it will collect and process the detected water level information. The detection processing block 15 will analyze and convert the collected water level data into numerical information that can be displayed intuitively. The water level information processed by the detection processing block 15 will be transmitted to the display screen 16. The operator can directly read the currently measured water level value through the display screen 16. During the operation of the instrument, the heat dissipation vent 5 opened inside the protective shell 1 can play a role in heat dissipation, ensuring that the internal electronic components of the instrument work in a suitable temperature environment, improving the stability and reliability of the instrument. The operator compares the measured water level value displayed on the display screen 16 with the known standard water level value.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
