Description

Technical Field

[0001] This utility model relates to the technical field of moisture content measurement devices, and in particular to a detachable soil and rock moisture content measurement probe. Background Technology

[0002] In fields such as geotechnical engineering, geological exploration, and environmental monitoring, accurate measurement of the moisture content of soil and rock is of great significance for assessing geological conditions, predicting geological hazards, guiding engineering construction, and protecting the ecological environment. Traditional soil and rock moisture content measurement probes often suffer from problems such as complex installation, difficult disassembly, poor measurement stability, and high maintenance costs, making it difficult to meet the high requirements of modern geotechnical engineering for measurement accuracy and efficiency.

[0003] Specifically, existing soil and rock moisture content measurement probes have shortcomings in their connection structure. On one hand, traditional probes typically consist of a transmitter head and two measuring probes, connected by a fixed steel pipe. Electrical connections between the transmitter head and the probes are made via wires placed inside the pipe. While this fixed pipe design ensures structural stability to some extent, it also introduces several drawbacks. For example, during installation, the fixed pipe length makes it difficult to adapt to measurements at different depths, often requiring custom-made pipes of varying lengths, increasing manufacturing costs and installation difficulty. Furthermore, disassembling the fixed pipe becomes extremely cumbersome and may even damage the probe or the pipe itself if repair or replacement is needed.

[0004] On the other hand, while some steel pipes using threaded connections offer a degree of detachability, these connections are prone to loosening and wear over long-term use. Due to the complex and variable environment of soil and rock measurements, probes may be subjected to various external forces such as vibration and impact, causing the threaded connections to gradually loosen and affecting the accuracy of the measurement data. Furthermore, thread wear can lead to connection failure, rendering the probe inoperable and even posing safety hazards.

[0005] Therefore, it is necessary to provide a new detachable soil moisture content measurement probe to solve the above-mentioned technical problems. Summary of the Invention

The inner wall of the second circular collar is fixed with a plurality of fixing blocks. The second circular collar slides on the bottom wall of the plurality of second sliding grooves through the plurality of fixing blocks.

[0011] When the sliding component is in a sliding state and one end of it is in contact with the inner side of the second cylindrical collar, the arc-shaped stop block extends and retracts through one side of the second cylindrical collar and exits through the other side of the second cylindrical collar. The arc-shaped stop block resets, so that the arc-shaped stop block and the second cylindrical collar are in a locked state.

[0012] Preferably, a transition connecting pipe is fixed to the bottom of the transmitter head. The surface of the transition connecting pipe is provided with a plurality of mounting grooves along its length. A circular collar slides on the surface of the transition connecting pipe.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Soil and rock moisture content measurement probes include capacitive and time-domain reflectometry methods:

[0033] The capacitive probe works on the principle of the relationship between the dielectric constant and water content of soil and rock. The probe consists of two electrodes. When the water content of the soil and rock changes, its dielectric constant also changes, resulting in a change in the probe's capacitance. By measuring this change in capacitance, the water content of the soil and rock can be calculated.

[0034] The working principle of Time Domain Reflectometry (TDR) is as follows: Utilizing the propagation characteristics of electromagnetic waves in soil and rock, the probe emits electromagnetic waves into the soil and rock. When the electromagnetic waves encounter substances with different dielectric constants, such as water and solid particles, they will be reflected. By measuring parameters such as the time and amplitude of the reflected waves, the water content of the soil and rock can be calculated.

[0035] In the specific implementation process, such as Figures 1 to 11 As shown, the transmitter includes a transmitter head 1 and two measuring probes 7. Both measuring probes 7 are located at the bottom of the transmitter head 1. Multiple steel pipe assemblies are also provided between the transmitter head 1 and the measuring probes 7. The multiple steel pipe assemblies are connected by multiple connecting components through threads. Circular collars 321 slide on the surface of each of the multiple steel pipe assemblies. Multiple sliding components for limiting the threads at the connection points of the steel pipe assemblies and connecting components slide on the surface of each of the multiple connecting components. One end of each sliding component engages with one side of the circular collar 321.

[0036] The soil moisture content measurement of this device is capacitive, and the connection part adopts a plug-in design. That is, the transmitter head 1 and the two measuring probes 7 are electrically connected by wires, and one end of the wires is provided with a plug. The bottom of the transmitter head 1 is provided with a socket. The plug and socket are installed in a plug-in manner, so that the transmitter head 1 and the two measuring probes 7 are electrically connected.

[0037] The conductor is located inside the steel pipe assembly. The steel pipe assembly has a hollow internal design. When installing the steel pipe assembly, first screw the steel pipe assembly and the connecting assembly together with threads. Then, use the sliding assembly to lock the steel pipe assembly and the connecting assembly together to prevent the threads from loosening. Finally, insert the end of the conductor with the plug into the socket at the bottom of the transmitter meter 1.

[0038] Among them, the preferred material for the steel pipe assembly is stainless steel, which has excellent corrosion resistance and can be used for a long time in humid and corrosive environments without easily rusting or corroding.

[0039] Specifically, in response to the problems of loosening and wear that easily occur at threaded connections in the prior art, this utility model has multiple sliding components slidably set on the surface of the connecting component to limit the threads of the steel pipe assembly and the connecting component. In use, the sliding components engage with the circular collar 321, preventing the threaded connection from loosening due to external vibration, impact and other factors during long-term use, which significantly improves the measurement stability of the measuring probe 7 and improves the accuracy and reliability of the measurement data.

[0040] Furthermore, by adjusting the number and length of the steel pipe assemblies, and utilizing the limiting mechanism of the sliding assembly and the circular collar, the probe can easily handle complex and varied measurement environments, such as measurement points at different depths of rock and soil, and those with different geological conditions. This not only improves maintenance efficiency but also reduces maintenance costs. Simultaneously, the limiting mechanism at the threaded connection effectively prevents loosening and wear, extending the probe's service life and further reducing operating costs.

[0041] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 As shown, each of the multiple steel pipe assemblies includes a steel pipe 2. Both ends of the multiple steel pipes 2 are threaded to one end of a multiple connecting assembly. Both ends of the steel pipes 2 are provided with multiple sliding grooves 21 along their length. The inner wall of each of the multiple sliding grooves 21 is provided with a limiting groove 211. The bottom wall of each of the multiple sliding grooves 21 is provided with a sliding assembly. Both ends of the sliding assembly slide on the inner wall of the limiting groove 211.

[0042] Multiple sliding components include a sliding plate 22. The top of the sliding plate 22 has a groove 221 and a buckle groove 25 at one end. The inner wall of the groove 221 has multiple limiting grooves 222. The sliding plate 23 slides on the inner wall of the groove 221. Multiple limiting blocks 223 are fixed on the outer side of the sliding plate 23. The sliding plate 23 slides on the inner wall of the multiple limiting grooves 222 through the multiple limiting blocks 223. A spring 231 is also fixed between the sliding plate 23 and the groove 221. The two ends of the spring 231 are fixedly connected to the bottom wall of the groove 221 and the bottom of the sliding plate 23, respectively. An arc-shaped stop block 24 is also fixed on the top of the sliding plate 23.

[0043] Multiple connecting components include steel pipe 2 3. Both ends of multiple steel pipe 1 2 are threaded to one end of multiple steel pipe 2 3. Both ends of multiple steel pipe 2 3 are fixed with multiple arc-shaped blocks 31. The multiple arc-shaped blocks 31 are arranged around the surface of the steel pipe 2 3, and slots 311 are formed between the multiple arc-shaped blocks 31. Both ends of multiple steel pipe 2 3 are provided with multiple sliding grooves 32 along their length direction. The multiple sliding grooves 32 are located inside the arc-shaped blocks 31. Both ends of steel pipe 2 3 are slidably provided with circular collars 321. Multiple fixing blocks 322 are fixed on the inner wall of the circular collars 321. The circular collars 32 slide on the bottom wall of the multiple sliding grooves 32 through the multiple fixing blocks 322.

[0044] When the sliding component is in a sliding state and one end of it is in contact with the inner side of the cylindrical collar 321, the arc-shaped stop 24 extends and retracts through one side of the cylindrical collar 321 and exits through the other side of the cylindrical collar 321. The arc-shaped stop 24 is reset, so that the arc-shaped stop 24 and the cylindrical collar 321 are in a locked state.

[0045] Specifically, in use, first pass one end of the wire through the steel pipe assembly and one end of the connecting assembly. At this time, the wire passes through the inside of multiple steel pipes 1 2 and multiple steel pipes 2 3. Tighten the multiple steel pipes 1 2 and multiple steel pipes 2 3 in sequence. After the multiple steel pipes 1 and steel pipes 2 3 are threaded together, hold the sliding plate 1 22 and push the sliding plate 1 22 from the buckle groove 25. The two ends of the sliding plate 1 22 slide on the inner wall of the limiting groove 2 222. Continue to push the sliding plate 1 22 so that one end of the sliding plate 1 22 passes through the circular collar. One side of the second ring 321 passes through, at which point the arc-shaped stop 24 contacts the inner wall of the second circular collar 321. The arc-shaped stop 24 at the top of the sliding plate 22 extends and retracts, sliding on the inner wall of the groove 221. The arc-shaped stop 24 compresses the spring 231 at its bottom, causing the spring 231 to elastically deform and contract, driving the arc-shaped stop 24 to continue sliding down the inner wall of the groove 221. One end of the arc-shaped stop 24 passes through one side of the second circular collar 321 and exits from the other side of the second circular collar 321. At this time, the arc-shaped stop... The spring 231 at the bottom of block 24 returns to its elastic deformation, causing the arc-shaped stop block 24 to slide and move upward along the inner wall of the groove 221. Since multiple limiting blocks 223 are fixed to the outer side of the sliding plate 23, the sliding plate 23 slides along the inner wall of multiple limiting grooves 222 via these limiting blocks 223. At this time, the arc-shaped stop block 24 resets, and its bottom does not disengage from the limiting groove 222. Furthermore, the side of the arc-shaped stop block 24 abuts against the side of the circular collar 321, completing the engagement. This mechanism is suitable for multiple steel pipes 2 and more... When disassembling steel pipe 2, press the sliding component between steel pipe 2 and steel pipe 3 respectively, that is, press the arc-shaped stop 24 which is in the locked state. At this time, the arc-shaped stop 24 slides down the inner wall of the groove 221, causing the spring 231 to be compressed and elastically deformed. The outer side of the arc-shaped stop 24 loses its abutment with the side of the circular collar 2 321. Manually fasten the buckle groove 25 to reset the slide plate 22. Then, twist steel pipe 2 and steel pipe 3 in sequence to complete the disassembly. The operation is simple and convenient.

[0046] refer to Figure 1 as well as Figure 11 As shown, a transition connecting pipe 11 is fixed at the bottom of the transmitter head 1. Multiple mounting grooves 111 are provided around the surface of the transition connecting pipe 11 along its length. A circular collar 12 slides on the surface of the transition connecting pipe 11. The inner side of the circular collar 12 slides on the bottom wall of the multiple mounting grooves 111. One end of the transition connecting pipe 11 is threadedly connected to one end of one of the steel pipes 3.

[0047] The bottom of the transmitter head 1 is equipped with a test assembly, which includes a transition connecting pipe 2 4, a stainless steel tee pipe 5, and a stainless steel elbow pipe 6. The connecting pipe 2 4 is threaded to one end of one of the steel pipes 1 2. The stainless steel tee pipe 5 is fixed to the bottom of the transition connecting pipe 2 4, the stainless steel elbow pipe 6 is fixed to the bottom of the stainless steel tee pipe 5, and two measuring probes 7 are respectively fixed to the two ends of the stainless steel elbow pipe 6.

[0048] The bottom of the transmitter head 1 is also provided with a probe protective cover 8, and both measuring probes 7 are located inside the probe protective cover 8. Furthermore, multiple through holes 81 are provided on the outside of the probe protective cover 8 to facilitate the entry of soil and rock.

[0049] One end of the conductor passes through multiple steel pipes 1 2 and multiple steel pipes 2 3. The multiple steel pipes 1 2 and multiple steel pipes 2 3 are connected to the power supply in the transmitter meter 1 through the grounding conductor for grounding treatment, thereby improving the safety of the device and eliminating the coupling capacitance between the grounding conductor and the steel pipe assembly. The two measuring probes 7 are the capacitance measuring module and the PT100 temperature measuring module, respectively. Both measuring probes 7 are made of nylon.

[0050] The probe protective cover 8 is made of stainless steel, and the measuring probes 7 are arranged in parallel on the same horizontal plane inside the probe protective cover 8, which ensures the accuracy of the detection.

[0051] Specifically, during actual measurement, the detection probe 7 is inserted into the soil and rock. The two measuring probes 7 and the cavity between them form a capacitive sensor, and the soil and rock to be measured become the dielectric. The capacitance value is detected by the detection probe 4, and the detection data is sent to the main control chip in the transmitter head 1 through the wires of the measuring probe 7 for subsequent detection.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
