Description

Technical Field

[0001] The invention relates to the technical field of brackets, in particular to a portable mobile bracket for a nuclear magnetic resonance water detector. Background Art

[0002] A surface nuclear magnetic resonance (SNMR) water detector is a geophysical exploration device based on the nuclear magnetic resonance phenomenon of hydrogen protons in groundwater under the influence of the Earth's magnetic field. The instrument uses a surface-mounted transmitting coil to apply a pulsed magnetic field at a specific frequency (the Larmor frequency) to the ground, causing the water protons to resonate and deflect. After the pulse ends, the instrument receives a weak induction signal (typically in the microvolt range) generated by the proton relaxation process. This signal is then used to invert and determine key parameters such as the depth, thickness, water content, and permeability of the underground aquifer. Conventional instruments consist of three main components: the NMR host system, the coil assembly, and the support structure. The coil assembly typically utilizes a single-turn closed-loop conductor structure made of multiple strands of insulated copper wire (Litz wire). Its length is determined by a predetermined diameter (typically ranging from 30 to 150 meters) and is laid on the ground in a circular or near-circular path. To maintain the coil's geometry and control its height above the ground (typically maintaining a clearance of 5 to 20 cm), it requires a support structure. Currently, the support structure often utilizes a tripod or modular support system. For example, it consists of a central main tripod (composed of carbon fiber or aluminum alloy legs) and auxiliary ground supports distributed around the circumference of the coil. The main tripod's legs radiate outward from the center, and the coil wires are mounted on mechanical nodes at the top of the legs and temporarily secured using clips, slides, or hooks. For electrical connection, the coil's two ends (the starting and ending ends) are connected to the host's high-voltage pulse output and signal receiving terminals, respectively, to form a complete circuit. Waterproof aviation plugs connect the segmented wires. The support design generally adopts a foldable structure for easy transportation.

[0003] The coil support structure of the existing nuclear magnetic resonance water detector bracket adopts fixed mechanical clips or hooks, which cannot dynamically adjust the coil height and clamping force according to the environment. As a result, the coil is prone to displacement, sagging or uneven height from the ground in complex terrain (such as steep slopes and vegetation areas) or in severe weather (such as strong winds and heavy rains), causing magnetic field distortion and signal distortion. At the same time, the coil deployment relies on manual wiring and fixation in sections, which is inefficient and prone to poor contact, restricting the exploration accuracy and timeliness. Therefore, in view of the above situation, there is an urgent need to develop a portable mobile bracket for nuclear magnetic resonance water detector to overcome the shortcomings in current practical applications.

DETAILED DESCRIPTION

[0029] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] See also Figures 1-12 The embodiment of the present invention provides a portable mobile support for a nuclear magnetic resonance water detector, comprising a support truncated table 1 on which a plurality of tripod rods 4 are rotatably mounted, and is characterized in that: 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, and support reinforcement airbags 15 are provided between adjacent support structures; The support truncated platform 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 respectively connected to the support reinforcement airbag 15 and the support structure, and is signal-connected to the monitoring and control module 14. According to the monitoring results of the monitoring and control module 14 during the use of the coil assembly, 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 reinforcement airbag 15 to expand, thereby adjusting the position state and support state of the coil assembly.

[0032] When the nuclear magnetic resonance water detector is performing detection work, the air source control system 8 is set up to work in coordination with the monitoring and control module 14, wherein the monitoring and control module 14 integrates multiple sensors such as laser rangefinder, three-axis anemometer, temperature and humidity transmitter, inclination MEMS and micro-pressure rain gauge. When the sensor in the monitoring and control module 14 detects that the ambient humidity is greater than 85% or the rainfall is greater than 20mm / h, the air source control system 8 is controlled to deliver high-pressure gas to the support structure on the support reinforcement airbag 15 and the coil support node 7, wherein the coil support node 7 can be set at any height of the tripod rod 4 and designed according to actual needs to ensure the smooth operation of the coil assembly. The installation position of the coil support node 7 is not specifically specified here. body limitation; at this time, the support structure drives the coil assembly to move, so that its ground clearance is increased from the base height of 15cm to more than 25cm, avoiding the influence of surface water causing high-voltage leakage and tall weeds; at the same time, the support reinforcement airbag 15 expands and fits tightly to the bottom of the coil assembly to form an anti-droop support to cope with the influence of rainfall and other factors that cause the coil assembly to be deformed by weight. According to the monitoring results of the coil assembly during use by the monitoring and control module 14, the air source control system 8 is automatically controlled to drive the support structure to move longitudinally on the coil support node 7 and to expand the support reinforcement airbag 15, thereby realizing automatic adjustment of the position state and support state of the coil assembly, providing convenience for the detection work of the staff and improving the accuracy of the detection results.

[0033] In one embodiment of the present invention, see Figures 1-12 , further comprising: a nuclear magnetic resonance water finder mounting base 2, the nuclear magnetic resonance water finder mounting base 2 being fixedly mounted on the supporting truncated table 1, and the nuclear magnetic resonance water finder provided on the nuclear magnetic resonance water finder mounting base 2 being electrically connected to the coil assembly; And a lifting handle groove 3 , wherein the lifting handle groove 3 is opened on the supporting circular platform 1 .

[0034] The support truncated platform 1 and the tripod support rod 4 are connected via a hinge portion 25; Among them, an arc-shaped moving rod 24 is fixedly installed on the tripod rod 4, and a locking portion 23 is fixedly installed on the arc-shaped moving rod 24; an arc-shaped positioning groove plate 22 is also fixedly installed on the supporting table 1, and the arc-shaped positioning groove plate 22 is connected to the locking portion 23.

[0035] During the detection process, the main unit of the nuclear magnetic resonance water detector is quickly positioned and installed through the guide pins and aviation plugs on the nuclear magnetic resonance water detector mounting base 2. The electrical connection can be completed by aligning the interface slot at the bottom of the main unit with the guide pin and pressing down about 10 cm. The lifting handle slot 3 is used to assist in carrying the entire bracket. The above are all existing technologies and will not be elaborated here.

[0036] In addition, by providing the arc-shaped positioning slot plate 22, the locking portion 23, the arc-shaped movable rod 24 and the hinge portion 25, the angle of the tripod rod 4 can be adjusted to cope with different detection environments. Among them, the locking portion 23 can be positioned in the form of screw tightening, so that after the arc-shaped movable rod 24 rotates a specified angle relative to the arc-shaped positioning slot plate 22, the two are tightened and locked so that the two cannot move relative to each other, thereby achieving the stability of the tripod rod 4 fixed in the specified position.

[0037] In one embodiment of the present invention, see Figures 1-12 , further comprising: a rotating cylindrical support foot 5, wherein the rotating cylindrical support foot 5 is rotatably mounted on the bottom end of the tripod support rod 4; A through hole 6, wherein the number of the through holes 6 is multiple, and the multiple through holes 6 are evenly opened on the rotating cylindrical support foot 5; and an anti-skid structure, which is located inside the rotating cylindrical support leg 5 and is driven by the air source control system 8 to move inside the rotating cylindrical support leg 5 .

[0038] The anti-slip structure comprises: A telescopic piston plate 29, wherein the telescopic piston plate 29 is slidably mounted in a sliding cavity in the rotating cylindrical support leg 5, and the sliding cavity is connected to the air source control system 8 through an air pipe 10; A push-pull rod 30 is fixedly mounted on the telescopic piston plate 29, and the push-pull rod 30 is slidably connected to the sliding cavity; An arc-shaped support plate 31, the 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 slots 32, and the guide slots 32 are connected to the slide rails provided on the inner wall of the rotating cylindrical support foot 5; And anti-slip ground spikes 33, the number of which is equal to the number of the 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 ground spikes 33 to be inserted into the multiple through holes 6 respectively.

[0039] Among them, the lengths of the multiple anti-slip spikes 33 may be different. After the multiple anti-slip spikes 33 are inserted into the through holes 6, they will extend to the outside of the rotating cylindrical support feet 5 and contact the ground (even insert into the soil), thereby ensuring the stability of the entire equipment.

[0040] Through the linkage design of the rotating cylindrical support foot 5 and the anti-slip ground spikes 33, when the terrain slope sensor detects an inclination angle greater than 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 ground spikes 33 extend from the through hole 6 and insert into the soil or contact the ground surface; at the same time, the monitoring and control module 14 controls the elongation of the support structure on the lower side of the slope to increase by 40% compared with the upper side of the slope according to the slope data, ensuring that the plane of the coil assembly is always parallel to the slope surface.

[0041] In one embodiment of the present invention, see Figures 1-12 , the supporting structure comprises: A height adjustment member 11, the height adjustment member 11 is fixedly mounted on the coil support node 7, and the height adjustment member 11 is also connected to the air source control system 8 via an air pipe 2 12; and a lifting rod 21, the lifting rod 21 passing through the coil support node 7 and connected to the height adjustment member 11, wherein the air source control system 8 drives the height adjustment member 11 to drive the lifting rod 21 to slide longitudinally on the coil support node 7; An arc-shaped slot seat 9 is also fixedly mounted on the lifting support rod 21 , and a coil assembly is placed in the arc-shaped slot seat 9 . A plurality of the arc-shaped slot seats 9 place the coil assembly in a circular structure on the tripod support rod 4 .

[0042] Both ends of the arc-shaped slot seat 9 are provided with a guide clamping portion 18; and the middle position of the arc-shaped slot seat 9 is also provided with an inverted triangular airbag 19, and the inverted triangular airbag 19 is connected to the air source control system 8 through the air pipe three 13.

[0043] When the monitoring and control module 14 detects an abnormality, the inverted triangular airbag 19 is inflated to expand the inverted triangular airbag 19 and squeeze the upper side of the coil assembly in the arc-shaped slot seat 9, thereby further ensuring the stability of the coil assembly in the arc-shaped slot seat 9.

[0044] The bottom end of each arc-shaped slot seat 9 is symmetrically provided with two telescopic cavities, and the telescopic cavities are connected to the air source control system 8 through a hose; A limiting slide 27 is slidably installed in each of the telescopic cavities, and a telescopic socket plate 17 is fixedly installed on one side of the limiting slide 27. One end of the telescopic socket plate 17 passes through the telescopic cavity and is slidably connected to the telescopic cavity. A return spring 28 is provided on the other side of the limiting slide 27, and the return spring 28 is fixedly connected to the inner wall of the telescopic cavity; The other end of the telescopic socket plate 17 is fixedly connected to the supporting reinforcement airbag 15, and an air outlet 20 and an air inlet 26 are provided on the telescopic socket plate 17, so that the supporting reinforcement 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.

[0045] The support and reinforcement airbag 15 is further provided with a plurality of elastic protrusions 16. When the support and reinforcement airbag 15 is expanded, the elastic protrusions 16 contact the bottom of the coil assembly to support and reinforce the coil assembly. In addition, when the tripod pole 4 is placed on the ground at different inclination angles, the telescopic socket plate 17 avoids interfering with the smooth rotation of the tripod pole 4 by sliding different lengths in the telescopic cavity.

[0046] 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 portion 18, when the wind speed sensor detects a strong wind of >6m / s, the air source control system 8 inflates the inverted triangular airbag 19 to expand it, applying a vertical downward clamping component and a horizontal relative clamping component to the wire placed in the arc-shaped slot seat 9, thereby ensuring the stability of the coil assembly during operation. In addition, the monitoring and control module 14 can also monitor the tension changes 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 environment coupling algorithm of the edge computing unit. Through the zoning control strategy of the support and reinforcement airbag 15, the height of the laser rangefinder scanning coil from the ground in the densely vegetated area, when it is detected that the height difference of the local area is greater than 5cm due to the support of the vegetation, the air source control system 8 will directionally inflate the support and reinforcement airbag 15 in the corresponding area, so that the elastic protrusion 16 lifts the wire to a uniform height; and for detection environments such as rainfall, the coil assembly part between the two tripod rods 4 may be deformed under the action of gravity due to the lack of support, thereby affecting the detection result. At this time, under the control of the monitoring and control module 14, multiple support and reinforcement airbags 15 can be expanded synchronously to lift the suspended part of the coil assembly, thereby avoiding deformation of the coil assembly, and the elastic protrusion 16 (the elastic protrusion 16 can be coated with anti-slip material) is squeezed by the coil assembly. It can be deformed, thereby forming 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 support rods 4 are connected by the support reinforcement airbags 15, during the expansion of the support reinforcement airbags 15, it is convenient to support the tripod support rods 4, thereby further improving the stability of the bracket. After the support reinforcement airbags 15 are contracted, they can be freely extended and retracted, which is convenient for the bracket to be stored and does not take up space; and this process can also work in conjunction with the height adjustment member 11, wherein the height adjustment member 11 is similar to the structure of a cylinder. The height adjustment member 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; In addition, by providing the structures of the telescopic cavity, the limiting slide plate 27, the telescopic socket plate 17 and the return spring 28, when the tripod rod 4 needs to be placed on the ground at different inclination 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 reinforcement airbag 15 and the exposed telescopic socket plate 17 (at this time, the return spring 28 is extended) to adapt to the different spacings between adjacent tripod rods 4 and avoid interference with the smooth adjustment of the tripod rods 4; Through the closed-loop control of the height adjustment member 11 and the arc-shaped positioning slot plate 22, in an environment with a large temperature difference between day and night, the temperature sensor monitors the changes in coil tension caused by the thermal expansion and contraction of the metal legs; when the tension deviates from the reference value by ±15%, the air source control system 8 adjusts the cylinder pressure in the height adjustment member 11 to drive the lifting support rod 21 to fine-tune the height to compensate for thermal deformation.

[0047] In summary, through the synergistic effect of the above-mentioned technical solutions, the efficient deployment and stable operation of the nuclear magnetic resonance water finder in a complex environment are achieved, from the rapid installation of the nuclear magnetic resonance water finder host through the nuclear magnetic resonance water finder mounting base 2 to the self-conducting deployment of the coil assembly in the arc slot seat 9, and then to the environmental adaptive control of multi-sensor fusion, the exploration efficiency and data reliability are significantly improved; the monitoring and control module 14 transmits data to the nuclear magnetic resonance water finder host through LoRa wireless, with a maximum coverage distance of 1km, providing all-weather technical support for deep water resource exploration.

[0048] In one embodiment of the present invention, see Figures 1-12 The specific working process of the monitoring and control module 14 includes the following steps: Step 1: Real-time collection of environmental parameters; The monitoring and control module 14 continuously collects data through a distributed sensor network: laser rangefinder (installed on the side wall of the arc-shaped card slot 9) → coil height above the ground; three-axis anemometer (on the top of the support truncated platform 1) → wind speed / direction; temperature and humidity transmitter (in the middle section of the tripod rod 4) → temperature / humidity; tilt MEMS (inside the rotating cylindrical support leg 5) → terrain slope; micro-pressure rain gauge (on the outer shell of the monitoring and control module 14) → precipitation intensity; strain sensor (embedded in the guide clamping part 18) → wire tension; Step 2: Identification of environmental risk patterns; The edge computing unit (ARM Cortex-M7) analyzes sensor data and triggers preset response thresholds: Humidity>85% or rainfall>20mm / h, marked as high humidity rainstorm mode; Wind speed>6m / s, marked as strong wind disturbance mode; Slope > 15° is marked as steep slope mode; If the local height difference is greater than 5cm (laser ranging), it is marked as vegetation support mode; If the conductor tension fluctuation is greater than ±15%, it is marked as thermal deformation compensation mode; Step 3: Actuator instruction generation; Generate control instructions based on the recognition pattern and transmit them to the gas source control system 8 via LoRa wireless: High humidity and rainstorm mode: drive the height adjustment member 11 to lift the coil to 25cm and expand the support and reinforcement airbag 15 to prevent sagging; Strong wind disturbance mode: inflate the inverted triangle airbag 19 to enhance the clamping force; Steep slope inclination mode: Extend the height adjustment member 11 on the lower side of the slope (increment of 40%) and extend the anti-slip spikes 33 (maximum 20 cm); Vegetation lifting mode: Directional inflatable support and reinforcement airbags 15 compensate for height differences; Thermal deformation compensation mode: adjust the cylinder pressure of height adjustment part 11 (±3cm stroke) to restore the reference tension; Step 4: Closed-loop feedback verification; After execution, sensor data is collected again to verify the control effect: the laser rangefinder confirms that the ground clearance meets the standard (error < ±1cm); the strain sensor detects the tension recovery baseline value (fluctuation < ±5%); the anemometer / tilt MEMS monitors whether the environmental disturbance persists; If the standard is not met, repeat step 3 for dynamic compensation Step 5: Security monitoring and alarm; Real-time monitoring of key safety indicators: if the grounding resistance (coil-earth) is less than 100MΩ, an audible and visual alarm will be triggered and the high voltage will be cut off; if the loop resistance is greater than 5Ω, it indicates abnormal wire contact; if the airbag pressure exceeds the limit (>0.5MPa), automatic pressure relief protection will be activated.
