Description

Technical Field

[0001] This utility model relates to the technical field of soil monitoring devices, specifically a real-time soil pH monitoring probe. Background Technology

[0002] Soil monitoring involves analyzing parameters such as soil moisture and pH to reflect the condition of the soil. Specifically, in environmental monitoring, specialized sensor probes are typically inserted into the soil to ensure that the soil pH is maintained at an appropriate level.

[0003] However, in the process of detecting pH using a probe, the probe needs to be inserted into the soil and moved to the area to be tested before the soil at that location can be analyzed. This means that during outdoor soil monitoring, the presence of stones and other debris in the soil can easily cause wear and tear on the probe upon contact with them. This wear affects the test results and consequently shortens the probe's lifespan. Therefore, we propose a real-time soil pH monitoring probe. Utility Model Content

[0004] To address the shortcomings of existing real-time soil pH monitoring probes, this invention provides a real-time soil pH monitoring probe with a pin extending into the interior of a protective sleeve. The protective sleeve is fitted over the outside of the monitoring probe, while the outer sleeve is fitted over the outside of the inner sleeve. Both the outer sleeve and the protective sleeve can be fitted over the outside of the monitoring probe, ensuring that the wear of the monitoring probe is reduced when it is inserted into the soil. This solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a real-time soil pH monitoring probe, including a pH meter, an extension rod fixedly connected to the lower end of the pH meter, connecting plates fixedly connected to the lower parts of both sides of the pH meter, an outer sleeve fixedly connected to the lower end of the connecting plates and sleeved outside the extension rod, an inner sleeve movably sleeved between the outer sleeve and the extension rod, a pin rod movably sleeved inside the inner sleeve, a position adjustment mechanism installed on the upper part of the pin rod, four sets of protective sleeves movably sleeved at the lower part of the inner sleeve via hinges, and a limit plate movably sleeved outside the outer sleeve.

[0006] Preferably, a monitoring probe for detecting soil pH is installed at the lower end of the extension rod, and the outer part of the monitoring probe is conical.

[0007] Preferably, a connecting sleeve is fixedly connected to the upper end of the inner sleeve, and a first screw is installed on the internal thread of the connecting sleeve. The lower end of the first screw is movably sleeved on the inner side of the connecting plate.

[0008] Preferably, the four sets of protective sleeves form a conical sleeve, which is fitted and installed on the outside of the monitoring probe.

[0009] Preferably, the position adjustment mechanism includes a disc and a threaded sleeve. The top end of the pin is fixedly connected to the disc, and the threaded sleeve is movably sleeved on the outside of the disc. The pin passes through the inner sleeve and is movably sleeved inside the protective sleeve, and the threaded sleeve is threadedly sleeved on the outside of the inner sleeve.

[0010] Preferably, the limiting plate is threaded with three sets of second screws, and the lower end of the second screws is fixedly connected to a support foot, the lower end of the support foot being attached to the foundation.

[0011] Preferably, the pH meter is equipped with a display screen and control buttons, and the two sets of connecting plates installed at the lower end of the pH meter are in a U-shape.

[0012] Compared with existing real-time soil pH monitoring probes, this invention has the following advantages:

[0013] 1. This real-time soil pH monitoring probe extends into the protective sleeve via a control pin rod. Simultaneously, the protective sleeve is fitted over the outside of the monitoring probe, and the outer sleeve is fitted over the outside of the extension rod. This means that when the monitoring probe is inserted into the soil, the protective sleeve and outer sleeve protect the extension rod and the outside of the monitoring probe, effectively preventing wear and tear on the outside of the monitoring probe due to premature contact with the soil when it is inserted into the soil to be tested. This extends the service life of the monitoring probe.

[0014] 2. This real-time soil pH monitoring probe adjusts the height of the disc by rotating the threaded sleeve. The disc then engages a pin inside the protective sleeve, preventing the protective sleeve from opening when inserted into the soil. Simultaneously, after reaching the desired position, the threaded sleeve moves downwards, releasing the pin from its confinement. At the same time, rotating the first screw moves the inner sleeve upwards, creating an opening on the outside of the probe. This ensures the probe is inserted into the soil and allows for the detection of soil pH. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A real-time soil pH monitoring probe includes a pH meter 1. An extension rod 2 is fixedly connected to the lower end of the pH meter 1. Connecting plates 4 are fixedly connected to the lower parts of both sides of the pH meter 1. An outer sleeve 5, fitted over the extension rod 2, is fixedly connected to the lower end of the connecting plates 4. The outer sleeve 5 protects the exterior of the extension rod 2. An inner sleeve 8 is movably fitted between the outer sleeve 5 and the extension rod 2, limiting the position of a protective sleeve 13. A pin 9 is movably fitted inside the inner sleeve 8. After the pin 9 extends into the interior of the protective sleeve 13, it ensures that the protective sleeve 13 stably fits against the exterior of the monitoring probe 3. A position adjustment mechanism is installed on the upper part of the pin 9, adjusting the height of the inner sleeve 8. Four sets of protective sleeves 13 are movably fitted to the lower part of the inner sleeve 8 via hinges 12. A limiting plate 14 is movably fitted outside the outer sleeve 5, adjusting the limiting plate 14 to the outside of the outer sleeve 5, i.e., adjusting the depth of the outer sleeve 5 extending into the soil.

[0023] Please see Figure 2 The lower end of the extension rod 2 is equipped with a monitoring probe 3 for detecting soil pH. The outer part of the monitoring probe 3 is conical. The monitoring probe 3 is installed at the lower end of the pH meter 1 through the extension rod 2. At the same time, the monitoring probe 3 is controlled to extend to the area to be tested. That is, the monitoring probe 3 can detect the pH of the soil in real time.

[0024] Please seeFigure 5 The upper end of the inner sleeve 8 is fixedly connected to the outer side of the connecting sleeve 6. The connecting sleeve 6 is threaded with a first screw 7. The lower end of the first screw 7 is movably sleeved on the inner side of the connecting plate 4. By controlling the inner sleeve 8 to be installed between the extension rod 2 and the outer sleeve 5, and simultaneously rotating the first screw 7, the first screw 7 and the connecting sleeve 6 perform threaded movement, that is, the position of the inner sleeve 8 inside the extension rod 2 and the outer sleeve 5 is adjusted, and the outer sleeve 5 is sleeved on the outside of the extension rod 2 and the inner sleeve 8, that is, the outer sleeve 5 provides protection for the outside of the extension rod 2.

[0025] Please see Figure 3 Four sets of protective sleeves 13 form a conical sleeve, which is fitted to the outside of the monitoring probe 3. The protective sleeve 13 is installed at the lower end of the inner sleeve 8 through the hinge 12. Under normal conditions, the protective sleeves 13 form a conical sleeve, which is fitted to the outside of the monitoring probe 3. That is, when the control extension rod 2 is inserted into the soil, the protective sleeve 13 protects the outside of the monitoring probe 3.

[0026] Please see Figure 4 The position adjustment mechanism includes a disc 10 and a threaded sleeve 11. The top of the pin 9 is fixedly connected to the disc 10, and the threaded sleeve 11 is movably sleeved on the outside of the disc 10. The pin 9 passes through the inner sleeve 8 and is movably sleeved inside the protective sleeve 13. The threaded sleeve 11 is threadedly sleeved on the outside of the inner sleeve 8. By rotating the threaded sleeve 11, the threaded sleeve 11 and the outside of the inner sleeve 8 are mutually threaded and limited. That is, the height of the pin 9 at the upper end of the inner sleeve 8 is adjusted by the disc 10, that is, the pin 9 stops limiting the protective sleeve 13. At the same time, when the inner sleeve 8 is controlled to move upward, the protective sleeve 13 moves outward, and the protective sleeve 13 stops covering the monitoring probe 3, controlling the monitoring probe 3 to contact the soil to be tested, and then the soil pH can be monitored.

[0027] Please see Figure 1 The limiting plate 14 has three sets of second screws 15 installed on its external threads. The lower end of the second screw 15 is fixedly connected to a support foot 16. The lower end of the support foot 16 is attached to the foundation. By adjusting the position of the limiting plate 14 outside the outer sleeve 5, the second screw 15 is rotated, and the second screw 15 pushes the support foot 16 to move downward. That is, the support foot 16 is installed on the upper end of the foundation to ensure that the outer sleeve 5 maintains stability when positioned inside the soil.

[0028] Please see Figure 1The pH meter 1 is equipped with a display screen and control buttons. The two sets of connecting plates 4 installed at the lower end of the pH meter 1 are in the shape of a U. The display screen and control buttons installed inside the pH meter 1 can limit the detection status in real time. At the same time, the U-shaped connecting plates 4 installed at the lower end of the pH meter 1 can be used to pull and fix the position of the outer jacket 5, and it is also convenient to hold the connecting plates 4 and press the outer jacket 5 into the soil.

[0029] Working principle: During use, depending on the required detection depth, adjust the position of the limiting plate 14 outside the outer sleeve 5. At the same time, control the rotation of the threaded sleeve 11, which drives the pin rod 9 to engage inside the protective sleeve 13. Simultaneously, press down on the pH meter 1, so that the protective sleeve 13 penetrates the soil, improving the convenience of inserting the device into the soil. After extending to the corresponding area, rotate the threaded sleeve 11 to control the pin rod 9 to stop limiting the position of the protective sleeve 13. Then rotate the first screw 7, which pushes the connecting sleeve 6 upward. That is, the inner clamp 8 is lifted from the position inside the extension rod 2 and the outer sleeve 5. At the same time, the protective sleeve 13 opens under the action of the monitoring probe 3, controlling the monitoring probe 3 to be exposed inside the soil. That is, the pH of the soil can be detected through the monitoring probe 3.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
