Abstract
Description
Technical Field
[0001] This invention relates to the field of support technology, specifically a portable mobile support for a nuclear magnetic resonance water finding instrument. Background Technology
[0002] Surface Nuclear Magnetic Resonance (SNMR) water finding instruments, as a geophysical exploration device, operate based on the nuclear magnetic resonance phenomenon of hydrogen protons in groundwater under the influence of the Earth's magnetic field. The instrument applies a specific frequency (Lamor frequency) excitation pulse magnetic field to the ground via a transmitting coil laid on the surface, causing the water protons to resonate and deflect. After the pulse ends, it receives the weak induced signal (typically on the order of microvolts) generated by the proton relaxation process, and then inverts to obtain key parameters such as the depth, thickness, water content, and permeability of the underground aquifer. In existing technology, such instruments mainly consist of three parts: the SNMR main system, the coil assembly, and the support structure. The coil assembly typically uses a single-turn closed-loop conductor structure, made of multi-strand insulated copper wire (Litz wire), with its length determined by a preset diameter (commonly ranging from 30 to 150 meters), laid on the ground in a circular or near-circular path. To maintain the coil geometry and control its height above the ground (usually requiring a gap of 5-20 centimeters), it relies on a support structure for fixation. Current support structures mostly employ tripods or modular support systems. For example, they consist of a central main tripod (composed of carbon fiber or aluminum alloy legs) and auxiliary supports distributed along the circumference of the coil. The legs of the main tripod radiate outwards from the center point, and the coil wires are mounted on mechanical nodes at the top of the legs, temporarily secured by clips, grooves, or hooks. For electrical connections, the two ends of the coil (start and end points) need to be connected to the high-voltage pulse output and signal receiving terminals of the main unit, respectively, forming a complete circuit. Waterproof aviation connectors are used to connect the segmented wires. The support structure is generally designed to be foldable for easy transport.
[0003] The existing NMR water finding instrument support structure uses fixed mechanical buckles or hooks, which cannot dynamically adjust the coil height and clamping force according to the environment. This leads to the coil being prone to displacement, sagging, or uneven height from the ground in complex terrain (such as steep slopes and vegetated areas) or in severe weather (such as strong winds and heavy rain), causing magnetic field distortion and signal distortion. At the same time, the coil deployment relies on manual wiring and fixing segment by segment, which is inefficient and prone to poor contact, restricting the accuracy and timeliness of exploration. Therefore, in view of the above situation, there is an urgent need to develop a portable mobile support for NMR water finding instruments to overcome the shortcomings in current practical applications. Summary of the Invention
[0004] The purpose of this invention is to provide a portable mobile support for a nuclear magnetic resonance water finding instrument to solve the problems mentioned in the background art.

[0016] And an anti-slip structure, which is located inside the rotating cylindrical support leg and is driven by the air source control system to move inside the rotating cylindrical support leg.

[0021] The system also includes anti-slip spikes, the number of which is equal to the number of through holes, and each spike is positioned opposite to one of the through holes. When the air source control system drives the telescopic piston plate and push rod to move within the slide cavity, it will push the anti-slip spikes to insert into the through holes.

[0023] A height adjustment component is fixedly installed on the coil support node, and the height adjustment component is also connected to the air source control system through an air pipe.
[0024] The system includes a lifting support rod that passes through the coil support node and is connected to the height adjustment component. The air source control system drives the height adjustment component to move the lifting support rod longitudinally on the coil support node.
[0025] Furthermore, an arc-shaped slot seat is fixedly installed on the lifting support rod, and a coil assembly is placed inside the arc-shaped slot seat. Multiple arc-shaped slot seats place the coil assembly in a circular structure on the tripod support rod.
[0026] As a further aspect of the present invention: both ends of the arc-shaped card slot are provided with guide clamping parts; and an inverted triangular airbag is provided in the middle of the arc-shaped card slot, the inverted triangular airbag being connected to the air source control system through an air tube.
[0027] As a further aspect of the present invention: each of the arc-shaped card slots has two telescopic cavities symmetrically arranged at its bottom end, and the telescopic cavities are connected to the air source control system via flexible hoses;
[0028] Each of the telescopic cavities is slidably installed with a limiting slide plate. A telescopic socket plate is fixedly installed on one side of the limiting slide plate.

[0031] As a further aspect of the present invention: the supporting and reinforcing airbag is also provided with a plurality of elastic protrusions. When the supporting and reinforcing airbag expands, the elastic protrusions contact the bottom of the coil assembly to provide support and reinforcement for the coil assembly.
[0032] As a further aspect of the present invention, the specific workflow of the monitoring and control module includes the following steps:
[0033] Step 1: Collect environmental parameters in real time, including the ground clearance of the coil assembly, wind speed, temperature and humidity, terrain slope, precipitation intensity and conductor tension;

[0036] Step 4: Collect feedback signals to verify the execution effect;
[0037] Step 5: Continuously monitor the grounding resistance > 100MΩ and the loop resistance < 5Ω.
[0038] Compared with the prior art, the beneficial effects of the present invention are:
[0039] 1. Environmental Adaptive Control: By monitoring and controlling the module in real time, parameters such as wind speed, humidity and slope are sensed, and the coil assembly’s ground clearance (e.g., raised to 25cm in heavy rain) and clamping force (e.g., increased to 800N in strong wind) are automatically adjusted, which significantly suppresses signal fluctuations caused by environmental interference.
[0040] 2. Rapid deployment and reliable connection: The arc-shaped card slot design enables the wires to be "pressed in and fixed", reducing the deployment time from the traditional 40 minutes to 3 minutes, and the loop resistance <1Ω ensures electrical stability;
[0041] 3. Dynamic terrain compensation: When the slope is greater than 15°, the support on the lower side of the slope is automatically extended and anti-slip spikes (maximum 20cm) are extended. Combined with closed-loop adjustment of height difference, the coil plane is always parallel to the slope, and the magnetic field distortion rate is reduced by 90%.
[0042] 4. Safety Redundancy Protection: Automatic high voltage cut-off when grounding resistance > 100MΩ, alarm triggered when loop resistance > 5Ω, and airbag pressure over-limit pressure relief protection, providing comprehensive prevention of risks in field operations;
[0043] 5.

Detailed Implementation
[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0058] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0059] Please see Figures 1-12 The present invention provides a portable mobile support for a nuclear magnetic resonance water finding instrument, comprising a supporting frustum 1, on which a plurality of tripod rods 4 are rotatably mounted, characterized in that:
[0060] Each of the tripod rods 4 is provided with a coil support node 7, and the coil support node 7 is provided with a support structure for clamping the coil assembly. A support and reinforcement airbag 15 is provided between adjacent support structures.
[0061] The supporting truncated cone 1 is also provided with an air source control system 8 and a monitoring and control module 14. The air source control system 8 is connected to the supporting reinforcement airbag 15 and the supporting structure respectively, and is signal connected to the monitoring and control module 14.
[0062] Based on the monitoring results of the coil assembly during use by the monitoring and control module 14, the air source control system 8 will be controlled to drive the support structure to move longitudinally on the coil support node 7 and the support and reinforcement airbag 15 to expand, thereby adjusting the position and support status of the coil assembly.
[0063] When the nuclear magnetic resonance water detector is performing its detection work, the gas source control system 8 and the monitoring and control module 14 work together. The monitoring and control module 14 integrates multiple sensors, including a laser rangefinder, a triaxial anemometer, a temperature and humidity transmitter, an inclination MEMS sensor, and a micro-pressure rain gauge. When the sensors in the monitoring and control module 14 detect that the ambient humidity is >85% or the rainfall is >20mm / h, the gas source control system 8 is controlled to deliver high-pressure gas to the support structure on the support and reinforcement airbag 15 and the coil support node 7. The coil support node 7 can be set at any height on the tripod rod 4, designed according to actual needs, to ensure the smooth operation of the coil assembly. The specific installation position of the coil support node 7 will not be specified here. The body is limited; at this time, the support structure drives the coil assembly to move, raising its ground clearance from the reference height of 15cm to more than 25cm, avoiding the impact of surface water accumulation causing high voltage leakage and tall weeds, etc.; at the same time, the support and reinforcement airbag 15 expands and fits tightly against the bottom of the coil assembly to form an anti-sagging support to cope with the impact of rainfall and other factors causing deformation of the coil assembly. Based on the monitoring results of the coil assembly during use by the monitoring and control module 14, the air source control system 8 automatically controls the support structure to move longitudinally on the coil support node 7 and the support and reinforcement airbag 15 to expand, thereby realizing the automatic adjustment of the position and support status of the coil assembly, providing convenience for the staff's detection work and improving the accuracy of the detection results.
[0064] In one embodiment of the present invention, please refer to Figures 1-12 It also includes: a nuclear magnetic resonance water finder mounting base 2, which is fixedly mounted on the supporting truncated cone 1, and the nuclear magnetic resonance water finder mounted on the nuclear magnetic resonance water finder mounting base 2 is electrically connected to the coil assembly;
[0065] And a lifting handle groove 3, which is formed on the supporting frustum 1.
[0066] The supporting frustum 1 and the tripod rod 4 are connected by a hinge 25;
[0067] The tripod rod 4 is also fixedly mounted with an arc-shaped moving rod 24, and a locking part 23 is fixedly mounted on the arc-shaped moving rod 24; the supporting frustum 1 is also fixedly mounted with an arc-shaped positioning groove plate 22, and the arc-shaped positioning groove plate 22 is connected to the locking part 23.
[0068] During the detection process, the main unit of the nuclear magnetic resonance water finder is quickly positioned and installed by the guide pin on the mounting base 2 and the aviation plug. The electrical connection can be completed by simply aligning the interface slot at the bottom of the main unit with the guide pin and pressing down about 10cm. The lifting handle slot 3 is used to assist in the overall handling of the support frame. All of the above are existing technologies and will not be described in detail here.
[0069] In addition, the angle of the tripod rod 4 can be adjusted by the arc-shaped positioning groove plate 22, the locking part 23, the arc-shaped moving rod 24 and the hinge part 25, so as to cope with different detection environments. The locking part 23 can be positioned by tightening screws, so that after the arc-shaped moving rod 24 rotates relative to the arc-shaped positioning groove plate 22 by a specified angle, the two are tightened and locked, so that the two cannot move relative to each other, thus achieving the stability of the tripod rod 4 fixed in the specified position.
[0070] In one embodiment of the present invention, please refer to Figures 1-12 It also includes: a rotating cylindrical support leg 5, which is rotatably mounted on the bottom end of the tripod rod 4;
[0071] Through holes 6, there are multiple through holes 6, and the multiple through holes 6 are evenly opened on the rotating cylindrical support leg 5;
[0072] And an anti-slip structure, which is located inside the rotating cylindrical support 5 and is driven by the air source control system 8 to move within the rotating cylindrical support 5.
[0073] The anti-slip structure includes:
[0074] Telescopic piston plate 29, which is slidably installed in the sliding cavity inside the rotating cylindrical support leg 5, and the sliding cavity is connected to the air source control system 8 through air pipe 10;
[0075] A push-pull rod 30 is also fixedly installed on the telescopic piston plate 29, and the push-pull rod 30 is slidably connected to the sliding cavity;
[0076] An arc-shaped support plate 31 is fixedly connected to the other end of the push-pull rod 30, and both ends of the arc-shaped support plate 31 are provided with guide grooves 32, which are engaged with the slide rails provided on the inner wall of the rotating cylindrical support leg 5.
[0077] And anti-slip spikes 33, the number of which is equal to the number of through holes 6, and are respectively arranged opposite to the multiple through holes 6. When the air source control system 8 drives the telescopic piston plate 29 and the push-pull rod 30 to move in the sliding cavity, it will push the multiple anti-slip spikes 33 to be inserted into the multiple through holes 6 respectively.
[0078] The lengths of the multiple anti-slip spikes 33 may be different. After the multiple anti-slip spikes 33 are inserted into the through hole 6, they will extend to the outside of the rotating cylindrical support leg 5 and contact the ground (or even insert into the soil), thereby ensuring the stability of the overall equipment.
[0079] Through the linkage design of the rotating cylindrical support leg 5 and the anti-slip spike 33, when the terrain slope sensor detects an inclination angle >15°, the air source control system 8 drives the telescopic piston plate 29 to push the push-pull rod 30, so that the anti-slip spike 33 extends out of the through hole 6 and inserts into the soil or contacts the ground surface; at the same time, the monitoring and control module 14 controls the extension of the support structure on the lower side of the slope to be 40% greater than that on the upper side of the slope according to the slope data, so as to ensure that the plane of the coil assembly is always parallel to the slope surface.
[0080] In one embodiment of the present invention, please refer to Figures 1-12 The supporting structure includes:
[0081] Height adjustment component 11 is fixedly installed on the coil support node 7, and the height adjustment component 11 is also connected to the air source control system 8 through air pipe 2 12;
[0082] And a lifting support rod 21, which passes through the coil support node 7 and is connected to the height adjustment component 11. The air source control system 8 drives the height adjustment component 11 to drive the lifting support rod 21 to slide longitudinally on the coil support node 7.
[0083] Furthermore, an arc-shaped slot seat 9 is fixedly installed on the lifting support rod 21. A coil assembly is placed inside the arc-shaped slot seat 9, and multiple arc-shaped slot seats 9 place the coil assembly in a circular structure on the tripod rod 4.
[0084] Both ends of the arc-shaped card slot 9 are provided with guide clamping parts 18; and the middle of the arc-shaped card slot 9 is also provided with an inverted triangular airbag 19, which is connected to the air source control system 8 through an air tube 13.
[0085] When the monitoring and control module 14 detects an abnormality, it inflates the inverted triangular airbag 19 by inflating it, thereby squeezing the upper part of the coil assembly located in the arc-shaped slot 9, which further ensures the stability of the coil assembly placed in the arc-shaped slot 9.
[0086] Each of the arc-shaped slot seats 9 has two telescopic chambers symmetrically arranged at its bottom end, and the telescopic chambers are connected to the air source control system 8 through a hose;
[0087] Each of the telescopic cavities is slidably installed with a limiting slide plate 27. A telescopic socket plate 17 is fixedly installed on one side of the limiting slide plate 27. One end of the telescopic socket plate 17 passes through the telescopic cavity and is slidably connected to the telescopic cavity.
[0088] A return spring 28 is provided on the other side of the limiting slide plate 27, and the return spring 28 is fixedly connected to the inner wall of the telescopic cavity;
[0089] The other end of the telescopic socket plate 17 is fixedly connected to the supporting and reinforcing airbag 15, and the telescopic socket plate 17 is provided with an air outlet 20 and an air inlet 26 so that the supporting and reinforcing airbag 15 is connected to the air source control system 8 through the air outlet 20, the air inlet 26, the telescopic cavity and the hose.
[0090] The support and reinforcement airbag 15 is also provided with a plurality of elastic protrusions 16. When the support and reinforcement airbag 15 expands, the elastic protrusions 16 contact the bottom of the coil assembly to provide support and reinforcement for the coil assembly.
[0091] In addition, when the tripod rod 4 is placed on the ground at different angles, the telescopic socket plate 17 avoids interfering with the smooth rotation of the tripod rod 4 by sliding different lengths within the telescopic cavity.
[0092] As can be seen from the above, during the detection operation, through the cooperation mechanism between the inverted triangular airbag 19 and the guide clamping part 18, when the wind speed sensor detects a strong wind >6m / s, the air source control system 8 inflates the inverted triangular airbag 19 to make it expand, and applies a vertically downward clamping force and a horizontally opposite clamping force to the wire placed in the arc-shaped slot seat 9, ensuring the stability of the coil assembly during operation; in addition, the monitoring and control module 14 can also monitor the tension change of the coil assembly in real time by setting a strain sensor, and dynamically adjust the control parameters to maintain the stability of the coil assembly by running the environmental coupling algorithm through the edge computing unit.
[0093] By employing a zoned control strategy with supporting and reinforcing airbags 15, the laser rangefinder scans the coil's height above the ground in densely vegetated areas. When a height difference greater than 5cm is detected in a localized area due to vegetation support, the air source control system 8 inflates the supporting and reinforcing airbags 15 in the corresponding area, raising the elastic protrusions 16 to a uniform height. Furthermore, in detection environments such as rainfall, the coil assembly between the two tripod rods 4, lacking support, may deform under gravity, affecting the detection results. In this case, under the control of the monitoring and control module 14, multiple supporting and reinforcing airbags 15 can expand synchronously to support the suspended portion of the coil assembly, preventing deformation. The elastic protrusions 16 (which can be coated with anti-slip material) are also supported by the compression of the coil assembly. It can deform, thus providing a certain limiting effect on the coil assembly, preventing the coil assembly from slipping and ensuring the stability of the coil assembly during operation. In addition, since the adjacent tripod rods 4 are connected by the support and reinforcement airbags 15, the support and reinforcement airbags 15 can easily support the tripod rods 4 during expansion, thereby further improving the stability of the support. After the support and reinforcement airbags 15 contract, they can freely extend and retract, making it easy to store the support without taking up space. Moreover, this process can also work in conjunction with the height adjustment component 11, which is similar to the structure of a cylinder. The height adjustment component 11 drives the lifting support rod 21 to lift the arc-shaped slot seat 9 and the coil assembly it carries, thereby adjusting the height of the coil assembly and ensuring the geometric accuracy of the coil in complex terrain.
[0094] In addition, through the structure of telescopic cavity, limiting slide plate 27, telescopic socket plate 17 and return spring 28, when the tripod rod 4 needs to be placed on the ground at different tilt angles according to different detection environments, the telescopic socket plate 17 slides different lengths in the telescopic cavity, thereby changing the total length of the supporting and reinforcing airbag 15 and the exposed telescopic socket plate 17 (at this time, the return spring 28 extends) to adapt to the different spacing between adjacent tripod rods 4 and avoid interference with the smooth adjustment of the tripod rod 4;
[0095] Through the closed-loop control of the height adjustment component 11 and the arc-shaped positioning slot plate 22, in an environment with large day-night temperature differences, the temperature sensor monitors the coil tension change caused by the thermal expansion and contraction of the metal support leg; when the tension deviates from the reference value by ±15%, the air source control system 8 adjusts the cylinder pressure in the height adjustment component 11 to drive the lifting support rod 21 to finely adjust the height to compensate for thermal deformation.
[0096] In summary, through the synergistic effect of the above technical solutions, the nuclear magnetic resonance water finding instrument has been efficiently deployed and stably operated in complex environments. From the rapid installation of the nuclear magnetic resonance water finding instrument main unit through the nuclear magnetic resonance water finding instrument mounting base 2 to the self-conducting deployment of the coil assembly in the arc-shaped slot base 9, and then to the environmental adaptive control of multi-sensor fusion, the exploration efficiency and data reliability have been significantly improved. The monitoring and control module 14 transmits data to the nuclear magnetic resonance water finding instrument main unit via LoRa wireless transmission, with a maximum coverage distance of 1km, providing all-weather technical support for deep water resource exploration.
[0097] In one embodiment of the present invention, please refer to Figures 1-12 The specific workflow of the monitoring and control module 14 includes the following steps:
[0098] Step 1: Real-time collection of environmental parameters;
[0099] The monitoring and control module 14 continuously collects data through a distributed sensor network: laser rangefinder (mounted on the side wall of the arc-shaped slot 9) → coil height above the ground; triaxial anemometer (supporting the top of the truncated cone 1) → wind speed / direction; temperature and humidity transmitter (middle section of the tripod rod 4) → temperature / humidity; tilt MEMS (inside the rotating cylindrical support 5) → terrain slope; micro-pressure rain gauge (outer shell of the monitoring and control module 14) → precipitation intensity; strain sensor (embedded in the guide clamp 18) → wire tension.
[0100] Step 2: Environmental risk pattern identification;
[0101] The edge computing unit (ARM Cortex-M7) analyzes sensor data and triggers a preset response threshold.
[0102] When humidity is greater than 85% or rainfall is greater than 20 mm / h, it is marked as a high-humidity rainstorm pattern.
[0103] Wind speed > 6 m / s is marked as a strong wind disturbance mode;
[0104] Slopes greater than 15° are marked as steep slopes.
[0105] Local height differences > 5cm (laser ranging) are marked as vegetation support mode;
[0106] If the conductor tension fluctuation is greater than ±15%, it is marked as thermal deformation compensation mode;
[0107] Step 3: Generating actuator instructions;
[0108] Control commands are generated based on the identification pattern and transmitted wirelessly to the gas source control system 8 via LoRa.
[0109] High humidity rainstorm mode: Drive height adjustment component 11 to raise the coil to 25cm and expand support reinforcement airbag 15 to prevent sagging;
[0110] Strong wind disturbance mode: Inflate the inverted triangular airbag 19 to enhance the clamping force;
[0111] Steep slope tilt mode: Extend the height adjustment piece 11 on the lower side of the slope (increment 40%) and extend the anti-slip spikes 33 (maximum 20cm).
[0112] Vegetation support mode: 15 directional inflatable support and reinforcement airbags compensate for height difference;
[0113] Thermal deformation compensation mode: Adjust the pressure of cylinder 11 of the height adjustment component (±3cm stroke) to restore the reference tension;
[0114] Step 4: Closed-loop feedback verification;
[0115] After execution, sensor data was collected again to verify the control effect: the laser rangefinder confirmed that the ground clearance met the standard (error < ±1cm); the strain sensor detected the tension recovery benchmark value (fluctuation < ±5%); the anemometer / tilt MEMS monitored whether environmental disturbances continued.
[0116] If the target is not met, repeat step 3 for dynamic compensation.
[0117] Step 5: Security monitoring and alarm;
[0118] Real-time monitoring of key safety indicators: if the grounding resistance (coil-to-ground) is less than 100MΩ, an audible and visual alarm will be triggered and the high voltage will be cut off; if the circuit resistance is greater than 5Ω, it will indicate abnormal wire contact; if the airbag pressure exceeds the limit (>0.5MPa), automatic pressure relief protection will be activated.
[0119] It should be noted that, in this invention, unless otherwise explicitly specified and limited, the terms "sliding," "rotating," "fixed," and "equipped" should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0120] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
Claims
1. A portable mobile support for a nuclear magnetic resonance water finding instrument, comprising a supporting frustum, wherein three tripod support rods are rotatably mounted below the supporting frustum, characterized in that: Each of the tripods is provided with a coil support node, and the coil support node is provided with a support structure for clamping the coil assembly. A support and reinforcement airbag is provided between adjacent support structures. The support platform is also equipped with an air source control system and a monitoring and control module. The air source control system is connected to the support reinforcement airbag and the support structure respectively, and is signal-connected to the monitoring and control module. Based on the monitoring results of the coil assembly during use by the monitoring and control module, the air source control system will be controlled to drive the support structure to move longitudinally on the coil support node and expand the support and reinforcement airbag, thereby adjusting the position and support status of the coil assembly. The support structure includes a height adjustment component, which is fixedly installed on the coil support node, and the height adjustment component is also connected to the air source control system through an air pipe. The system includes a lifting support rod that passes through the coil support node and is connected to the height adjustment component. The air source control system drives the height adjustment component to move the lifting support rod longitudinally on the coil support node. Furthermore, an arc-shaped slot seat is fixedly installed on the lifting support rod, and a coil assembly is placed inside the arc-shaped slot seat. Multiple arc-shaped slot seats place the coil assembly in a circular structure on the tripod support rod. Both ends of the arc-shaped card slot are provided with guide clamping parts; and an inverted triangular airbag is provided in the middle of the arc-shaped card slot, which is connected to the air source control system through an air tube. When the wind speed sensor detects strong winds, the air source control system inflates the inverted triangular airbag to expand it, applying a vertically downward clamping force and a horizontally opposite clamping force to the coil assembly placed in the arc-shaped slot, ensuring the stability of the coil assembly during operation. Each of the arc-shaped card slots has two telescopic cavities symmetrically arranged at its bottom end. A limiting slide plate is slidably installed in each telescopic cavity. A telescopic socket plate is fixedly installed on one side of the limiting slide plate, and the other end of the telescopic socket plate is fixedly connected to the supporting and reinforcing airbag. By using a zoned control strategy for supporting and reinforcing airbags, when a height difference greater than a certain value is detected in a local area due to vegetation support, the air source control system directionally inflates the supporting and reinforcing airbags in the corresponding area to lift the coil assembly; for rain detection environments, the monitoring and control module controls multiple supporting and reinforcing airbags to expand synchronously to support the coil assembly and prevent deformation of the suspended parts of the coil assembly. By incorporating a telescopic cavity, a limiting slide plate, and a telescopic socket plate, the telescopic socket plate can slide different lengths within the telescopic cavity, thereby altering the total length of the supporting and reinforcing airbag and the exposed telescopic socket plate to accommodate different spacing between adjacent tripod rods.
