Description

Technical Field

[0001] The present invention belongs to the technical field of electromagnetic fluid detection in mining areas, and specifically relates to an electromagnetic fluid detection device and method for mining areas. Background Art

[0002] When detecting electromagnetic fluid in a mining area, the earth potential method can be used. The earth potential method is a frequency-domain potential sounding method that sends alternating currents of different frequencies into the ground through a finite-length grounded wire current source and measures the potential change in real time within a certain range on the ground. When using the earth potential method for detection, an earth potential collector is required;

[0003] When using the earth potential collector, electrodes need to be buried. Usually, there are circular wiring and horizontal wiring. When burying electrodes, both require a lot of manpower and material resources. Especially for arid or hard-surface areas, it is extremely difficult to bury electrodes.

[0004] In view of this, the present invention proposes an electromagnetic fluid detection device and method for mining areas to solve the above technical problems. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and be able to assist in inserting the electrode into the ground without using tools, reducing the difficulty of electrode burial, the present invention provides an electromagnetic fluid detection device and method for mining areas.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an electromagnetic fluid detection device for mining areas, including: an earth potential collector, on which an electrode is provided; the electromagnetic fluid detection device for mining areas further includes: an auxiliary unit, the auxiliary unit is provided on the electrode, and the auxiliary unit can assist in inserting the electrode into the ground without using tools, reducing the difficulty of electrode burial.

[0007] Preferably, the auxiliary unit includes: a first seat, the bottom of the first seat is rotatably connected to a first cylinder, the top of the first seat is fixedly connected to a first handle, a first plate is slidably connected inside the first cylinder, the top of the first plate is fixedly connected to a first rod, the first rod passes through the first cylinder, the first seat and the first handle and exposes above the top of the first handle, and the first rod is slidably connected to the first cylinder, the first seat and the first handle; the bottom of the first plate is fixedly connected to the electrode; a digging plate, several digging plates are rotatably connected to the bottom of the first cylinder and a torsion spring is provided at the connection part; a first motor, the first motor is fixedly connected inside the first seat, a gear ring is fixedly connected to the top of the first cylinder and inside the first seat, and the output end of the first motor is fixedly connected to a first gear, and the first gear meshes with the gear ring.

[0008] Preferably, a connection port is fixedly installed on the side of the No. 1 handle, the No. 1 rod is a hollow structure, a notch is provided on the side wall of the No. 1 rod at a position corresponding to the connection port, a wiring is fixedly connected to the top of the electrode, and the wiring passes through the No. 1 plate and the inside of the No. 1 rod and out of the connection port;

[0009] When the torsion spring is in its original position, the digging floor is horizontal, and this position is the extreme position of the digging floor movement. Hold handle No. 1 and start motor No. 1. Motor No. 1 drives the gear ring, which drives tube No. 1 to rotate, and then the digging floor rotates to break the ground. After breaking the ground, hold handle No. 1 and push rod No. 1 downward. Rod No. 1 pushes the electrode into the soil. During this process, the electrode contacts and squeezes the digging floor, and the digging floor rotates and expands outward, so that the electrode can move out of tube No. 1. During the rotation of tube No. 1, rod No. 1 does not rotate, and thus the electrode wiring does not rotate.

[0010] Preferably, a piston plate is fixedly connected to the No. 1 rod and located above the No. 1 plate, the piston plate is slidably connected to the No. 1 cylinder, and the interior of the No. 1 cylinder and located between the piston plate and the No. 1 plate is filled with a conductive medium;

[0011] The conductive medium is salt water or conductive gel. When the soil is dry, the electrode is prone to poor contact with the soil, which affects the detection accuracy. Therefore, when the soil is dry, salt water or conductive gel needs to be poured at the electrode to ensure the contact between the electrode and the ground. Therefore, a conductive medium is filled inside the No. 1 tube and between the piston plate and the No. 1 plate. When the electrode is buried in the soil, the conductive medium also enters the soil and is poured into the electrode, ensuring sufficient contact between the electrode and the soil.

[0012] Preferably, overflow holes are provided near the bottom of both side walls of the No. 1 tube, and a plurality of connecting platforms are fixedly connected to the positions of the No. 1 rod corresponding to the overflow holes, each of the connecting platforms is fixedly connected to a No. 1 spring, and the other end of each of the No. 1 springs is fixedly connected to a hemispherical block, and the hemispherical block can be embedded in the overflow hole;

[0013] When the No. 1 rod does not push the electrode into the soil, the overflow hole is located between the piston plate and the No. 1 plate. When the No. 1 tube rotates, the No. 1 rod does not rotate, so the hemispherical block intermittently enters and exits the overflow hole, and the conductive medium intermittently flows out of the overflow hole. During the drilling of the No. 1 tube, the overflowed conductive medium wets the soil, making it easier to drill. During the drilling process, the conductive medium is kept added to play a stirring role, so that the conductive medium and the soil are mixed more evenly, and after contacting the motor, it is not easy to cause poor contact. The hemispherical block can be embedded in the overflow hole, making the overflow hole less likely to be blocked. At the same time, with the cooperation of the No. 1 spring, the hemispherical block intermittently enters the overflow hole, which increases the vibration during the drilling of the No. 1 tube, making it easier to shake the drilled soil from the borehole wall and the No. 1 tube to the bottom of the No. 1 tube, making it easier to contact the electrode after the electrode is inserted.

[0014] Preferably, a moisturizing cylinder is threadedly connected to the top of the first rod. The inside of the moisturizing cylinder communicates with the inside of the first rod, and the inside of the moisturizing cylinder is filled with a conductive medium. On both sides of the bottom of the first rod, there are first openings. Inside the first plate, a shielding plate is slidably connected corresponding to the position of the first openings. A second spring is fixedly connected between one side of the shielding plate and the inside of the first plate. On the other side of the shielding plate, a first telescopic rod is fixedly connected, and the first telescopic rod is fixedly connected to the inside of the first plate. Inside the first plate, insertion rods are slidably connected corresponding to the position of each first telescopic rod. A third spring is fixedly connected between each insertion rod and the inside of the first plate, and the insertion rod can extend out of the inside of the first plate. The inside of the insertion rod is hollow, and a detection plate is slidably connected inside the insertion rod. One side of the detection plate is filled with a water-absorbing substance and the other side is hollow. An elastic tube is fixedly connected to the end of the insertion rod, and the elastic tube connects the hollow part inside the insertion rod with the inside of the first telescopic rod. A number of water-permeable holes are provided on the side wall of the insertion rod at the position of the water-absorbing substance. When the water-absorbing substance expands, it pushes the detection plate to move, drives the first telescopic rod to extend, and further drives the shielding plate to block the first openings. An elastic shielding film is fixedly connected between the top of the first plate and the shielding plate.

[0015] When the first plate disengages from the first cylinder and enters the soil, under the tension of the third spring, the insertion rod is inserted into the soil. On the one hand, it realizes fixation, which is not conducive to the loosening of the electrode and enables better detection. On the other hand, when the insertion rod is inserted into the soil, it compresses the soil and slides the soil, causing the soil to fall and squeeze the electrode, which is conducive to better contact between the electrode and the soil. In addition, if the detection is carried out for a long time and the electrode is always inserted into the soil, when the sun shines high and the temperature keeps rising, after pouring in the conductive medium, the electrode is also likely to change from wet to dry, which is also likely to cause poor contact between the electrode and the soil and affect the detection. Therefore, a moisturizing cylinder is provided, and the inside of the insertion rod is filled with a water-absorbing substance. The water-absorbing substance can be substances such as sodium polyacrylate, gelatin, and polyvinyl alcohol, which realizes the purpose of detection. When the temperature rises, the water-absorbing substance dehydrates and its volume decreases. Under the extrusion of the second spring, the shielding plate opens the first openings, and the conductive medium in the moisturizing cylinder enters the first rod under the action of gravity, flows out from the first openings, and enters the soil, realizing the purpose of continuous moisturization, so that the electrode and the soil continuously maintain sufficient contact. In the case of wet soil, the water-absorbing substance expands, pushes the detection plate to move, drives the first telescopic rod to extend, and further drives the shielding plate to block the first openings to prevent the leakage of the conductive medium. Therefore, the above realizes the automatic detection of whether the soil is dry and ensures better detection by the electrode. The first rod and the moisturizing cylinder are threadedly connected and can be removed, and the conductive medium can be added to the first rod and the moisturizing cylinder accordingly. The elastic shielding film is provided to prevent soil from entering the first plate.

[0016] Preferably, at the bottom of the inner wall of the first cylinder and corresponding to the position of each digging floor, a first groove is provided. At the top of each first groove, a support rod is rotatably connected. At the top of each digging floor, a second groove is provided. A sliding block is slidably connected in the second groove. The other end of the support rod is rotatably connected to the side surface of the corresponding sliding block.

[0017] Preferably, elastic membranes are covered in the first groove and the second groove;

[0018] When the digging floor horizontally digs the ground, a triangle is formed among the side wall of the first cylinder, the support rod and the digging floor, which has stability and forms a supporting effect to ensure the stability of the digging floor during digging; when the electrode pushes the digging floor, the support rod rotates relative to the first cylinder and the sliding block, the sliding block slides, and the support rod enters the first groove and the second groove for storage; elastic membranes (not shown in the figure) are covered in the first groove and the second groove to ensure that soil does not enter the first groove and the second groove, so that the support rod can enter the first groove and the second groove.

[0019] A method for detecting electromagnetic fluid in a mining area, which uses a device for detecting electromagnetic fluid in a mining area described above, includes the following steps:

[0020] S1: Use a geopotential acquisition instrument to detect the electromagnetic fluid in the mining area; during detection, the electrode needs to be buried.

[0021] S2: During burial, hold the first handle by hand, start the first motor, the first motor drives the gear ring, drives the first cylinder to rotate, and then the digging floor rotates to break the ground. After breaking the ground, hold the first handle by hand and push the first rod downward. The first rod pushes the electrode into the soil. During this process, the electrode contacts and squeezes the digging floor, and the digging floor rotates and expands outward, so that the electrode can move out of the first cylinder.

[0022] S3: When the electrode enters the soil, the conductive medium also enters the soil and is poured at the electrode to ensure full contact between the electrode and the soil; in addition, if the detection is carried out for a long time and the electrode is always inserted into the soil, if the sun shines brightly and the temperature keeps rising, after pouring the conductive medium, the electrode is also likely to change from wet to dry, which is also likely to cause poor contact between the electrode and the soil and affect the detection. Therefore, a moisturizing cylinder is provided. The inside of the inserting rod is filled with a water-absorbing substance, which can be substances such as sodium polyacrylate, gelatin, polyvinyl alcohol, etc. The purpose of detection is achieved. When the temperature rises, the water-absorbing substance dehydrates and the volume decreases. Under the extrusion of the second spring, the baffle plate opens the first port, and the conductive medium in the moisturizing cylinder enters the first rod under the action of gravity, flows out from the first port, and enters the soil to achieve the purpose of continuous moisturizing, so that the electrode and the soil continuously maintain full contact.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. For a mine electromagnetic fluid detection device and method according to the present invention, when burying, hold the first handle by hand, start the first motor, the first motor drives the gear ring, drives the first cylinder to rotate, and then the digging floor rotates to break the ground. After breaking the ground, hold the first handle by hand and push the first rod downward. The first rod pushes the electrode into the soil. During this process, the electrode contacts and presses the digging floor, and the digging floor rotates and expands outward, enabling the electrode to move out of the first cylinder.

[0025] 2. For a mine electromagnetic fluid detection device and method according to the present invention, when the electrode enters the soil, the conductive medium also enters the soil and is poured at the electrode, ensuring full contact between the electrode and the soil; in addition, if detecting for a long time and the electrode is always inserted into the soil, when the sun shines brightly and the temperature keeps rising, after pouring the conductive medium, it is also easy for the electrode to change from wet to dry, which is also likely to cause poor contact between the electrode and the soil and affect the detection. Therefore, a moisture preservation cylinder is provided. The inside of the inserting rod is filled with a water-absorbing substance, and the water-absorbing substance can be substances such as sodium polyacrylate, gelatin, and polyvinyl alcohol. The purpose of detection is achieved. When the temperature rises, the water-absorbing substance dehydrates and its volume decreases. Under the extrusion of the second spring, the shielding plate opens the first opening, and the conductive medium in the moisture preservation cylinder enters the first rod under the action of gravity, flows out from the first opening, and enters the soil, achieving the purpose of continuous moisture preservation, so that the electrode and the soil continuously maintain sufficient contact.

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] As shown in Figure 1 、 Figure 3 ;

[0038] A mine electromagnetic fluid detection device described in the present invention includes: a ground potential collector, and an electrode 1 is arranged on the ground potential collector; the mine electromagnetic fluid detection device further includes: an auxiliary unit 2, and the auxiliary unit 2 is arranged on the electrode 1, and the auxiliary unit 2 can assist in inserting the electrode 1 into the ground without using tools, reducing the burial difficulty of the electrode 1.

[0039] During operation, when using the ground potential collector, it is necessary to bury the electrode 1. Usually, there are loop wiring and horizontal wiring. When burying the electrode 1, both require manpower and material resources. Especially for arid or hard-surface areas, it is extremely difficult to bury the electrode 1; therefore, an auxiliary unit 2 is arranged on the electrode 1, and the auxiliary unit 2 can assist in inserting the electrode 1 into the ground without using tools, reducing the burial difficulty of the electrode 1.

[0040] As a specific implementation manner of the present invention, as shown in Figure 1 、 Figure 2 、 Figure 5 、 Figure 6As shown, the auxiliary unit 2 includes: a No. 1 seat 21, the bottom of the No. 1 seat 21 is rotatably connected to a No. 1 barrel 22, the top of the No. 1 seat 21 is fixedly connected to a No. 1 handle 23, the interior of the No. 1 barrel 22 is slidably connected to a No. 1 plate 24, the top of the No. 1 plate 24 is fixedly connected to a No. 1 rod 25, the No. 1 rod 25 penetrates the No. 1 barrel 22, the No. 1 seat 21 and the No. 1 handle 23 and is exposed at the top of the No. 1 handle 23, the No. 1 rod 25 is slidably connected to the No. 1 barrel 22, the No. 1 seat 21 and the No. 1 handle 23; the bottom of the No. 1 plate 24 is fixedly connected to the electrode 1; a digging floor 26, the bottom of the No. 1 barrel 22 is rotatably connected to a plurality of digging floors 26 and a torsion spring is provided at the connecting portion; a No. 1 motor 27, the No. 1 seat 21 is fixedly connected to a No. 1 motor 27, the top of the No. 1 barrel 22 and located inside the No. 1 seat 21 is fixedly connected to a gear ring 28, the output end of the No. 1 motor 27 is fixedly connected to a No. 1 gear 29, and the No. 1 gear 29 is meshed with the gear ring 28;

[0041] like Figure 5 As shown, a connection port 3 is fixedly installed on the side of the No. 1 handle 23, the No. 1 rod 25 is a hollow structure, and a notch is provided on the side wall of the No. 1 rod 25 corresponding to the connection port 3. A connection 31 is fixedly connected to the top of the electrode 1, and the connection 31 passes through the No. 1 plate 24 and the No. 1 rod 25 and passes out from the connection port 3;

[0042] During operation, when the torsion spring is in its original position, the digging floor 26 is horizontal, and this position is the limit position of the movement of the digging floor 26. Hold the No. 1 handle 23 and start the No. 1 motor 27. The No. 1 motor 27 drives the gear ring 28, drives the No. 1 cylinder 22 to rotate, and then the digging floor 26 rotates to break the ground. After breaking the ground, hold the No. 1 handle 23 and push the No. 1 rod 25 downward. The No. 1 rod 25 pushes the electrode 1 into the soil. During this process, the electrode 1 contacts and squeezes the digging floor 26, and the digging floor 26 rotates and expands outward, so that the electrode 1 can move out of the No. 1 cylinder 22; during the rotation of the No. 1 cylinder 22, the No. 1 rod 25 does not rotate, and then the connection 31 of the electrode 1 does not rotate.

[0043] As a specific embodiment of the present invention, Figure 5 As shown, a piston plate 4 is fixedly connected to the No. 1 rod 25 and located above the No. 1 plate 24, and the piston plate 4 is slidably connected to the No. 1 cylinder 22, and the interior of the No. 1 cylinder 22 and located between the piston plate 4 and the No. 1 plate 24 is filled with a conductive medium;

[0044] During operation, the conductive medium is salt water or conductive gel. When the soil is dry, the electrode 1 is prone to poor contact with the soil, which affects the detection accuracy. Therefore, when the soil is dry, salt water or conductive gel needs to be poured at the electrode 1 to ensure the contact between the electrode 1 and the ground; therefore, a conductive medium is filled inside the No. 1 tube 22 and between the piston plate 4 and the No. 1 plate 24. When the electrode 1 is buried in the soil, the conductive medium also enters the soil and is poured into the electrode 1, ensuring sufficient contact between the electrode 1 and the soil.

[0045] As a specific embodiment of the present invention, as Figure 5 shown, overflow holes 41 are provided at positions near the bottom of both side walls of the first cylinder 22. A number of connecting platforms 42 are fixedly connected to the part of the first rod 25 corresponding to the overflow holes 41. Each connecting platform 42 is fixedly connected with a first spring 43, and the other end of each first spring 43 is fixedly connected with a hemispherical block 44, and the hemispherical block 44 can be embedded into the overflow hole 41;

[0046] When the first rod 25 does not push the electrode 1 into the soil, at this time, the overflow hole 41 is located between the piston plate 4 and the first plate 24. When the first cylinder 22 rotates, the first rod 25 does not rotate, so the hemispherical block 44 intermittently enters and exits the overflow hole 41, and the conductive medium intermittently flows out from the overflow hole 41. During the drilling process of the first cylinder 22, the overflowing conductive medium wets the soil, making it easier to drill; and during the drilling process, the addition of the conductive medium is maintained, which plays a stirring role, making the mixing of the conductive medium and the soil more uniform. After contacting the motor, it is not easy to cause poor contact; the hemispherical block 44 can be embedded into the overflow hole 41, making the overflow hole 41 not easily blocked; at the same time, with the cooperation of the first spring 43, the hemispherical block 44 intermittently enters the overflow hole 41, increasing the vibration during the drilling process of the first cylinder 22, and it is easier to shake the drilled soil from the drilling wall and the first cylinder 22 to the bottom of the first cylinder 22, which is easy to contact with the electrode 1 after the electrode 1 is inserted.

[0047] As a specific embodiment of the present invention, as Figure 5 、 Figure 8As shown in the figure, a moisturizing cylinder 5 is threadedly connected to the top of the first rod 25. The inside of the moisturizing cylinder 5 is communicated with the inside of the first rod 25, and the inside of the moisturizing cylinder 5 is filled with a conductive medium; on both sides of the bottom of the first rod 25, there are first openings 51; a shutter 52 is slidably connected inside the first plate 24 corresponding to the position of the first opening 51. One side of the shutter 52 is fixedly connected to the inside of the first plate 24 by a second spring 53, and the other side of the shutter 52 is fixedly connected to a first telescopic rod 54, and the first telescopic rod 54 is fixedly connected to the inside of the first plate 24; inside the first plate 24 and corresponding to the position of each first telescopic rod 54, there is a plug 55 slidably connected. A third spring 56 is fixedly connected between each plug 55 and the inside of the first plate 24, and the plug 55 can extend out of the inside of the first plate 24; the inside of the plug 55 is hollow, and a detection plate 57 is slidably connected inside the plug 55. One side of the detection plate 57 is filled with a water-absorbing substance 58 and the other side is hollow. An elastic tube 59 is fixedly connected to the end of the plug 55. The elastic tube 59 connects the hollow part inside the plug 55 with the inside of the first telescopic rod 54. A number of water-permeable holes 591 are provided on the side wall of the plug 55 at the position of the water-absorbing substance 58; when the water-absorbing substance 58 expands, it pushes the detection plate 57 to move, drives the first telescopic rod 54 to extend, and further drives the shutter 52 to block the first opening 51; an elastic shielding film 592 is fixedly connected between the top of the first plate 24 and the shutter 52;

[0048] During operation, when the first plate 24 detaches from the first cylinder 22 and enters the soil, under the stretching and contraction of the third spring 56, the insertion rod 55 is inserted into the soil. On the one hand, fixation is achieved, preventing the loosening of the electrode 1 and enabling better detection. On the other hand, when the insertion rod 55 is inserted into the soil, it squeezes and stirs the soil, causing the soil to fall and squeeze the electrode 1, facilitating better contact between the electrode 1 and the soil. In addition, if long-term detection is carried out and the electrode 1 remains inserted into the soil all the time, when the sun shines brightly and the temperature keeps rising, after pouring in the conductive medium, the area around the electrode 1 is also likely to change from wet to dry, which can also lead to poor contact between the electrode 1 and the soil, affecting detection. Therefore, a moisture-holding cylinder 5 is provided. The inside of the insertion rod 55 is filled with a water-absorbing substance 58, which can be sodium polyacrylate. Sodium polyacrylate has the characteristics of swelling when absorbing water and shrinking when losing water. Sodium polyacrylate performs well at room temperature and can effectively function at temperatures from 0 to 80 degrees Celsius. The volume of sodium polyacrylate can increase by hundreds of times after absorbing water. Before installing the moisture-holding cylinder 5, sodium polyacrylate can be allowed to absorb enough water in advance to fully expand in volume, keeping the first opening 51 closed. After the electrode 1 is inserted into the soil, the conductive medium filled inside the first cylinder 22 and located between the piston plate 4 and the first plate 24 is poured down, passing over the insertion rod 55 again, causing the water-absorbing substance 58 to absorb water again. When long-term monitoring is required, for example, in some cases, monitoring for several days or months is needed. In dry conditions, combined with rising temperatures, the soil becomes drier and drier, which will also cause sodium polyacrylate to dehydrate. After dehydration, its volume decreases. Under the extrusion of the second spring 53, the first telescopic rod 54 shortens, squeezing the detection plate 57, and then squeezing the water-absorbing substance 58, creating space for the baffle plate 52 to open the first opening 51. When the second spring 53 is in its original position, the baffle plate 52 is separated from the first opening 51, that is, the first opening 51 is in an open state.

[0049] Therefore, adding the water-absorbing substance 58 achieves the purpose of detection. When the temperature rises, the water-absorbing substance 58 dehydrates and its volume decreases. Under the extrusion of the second spring 53, the baffle plate 52 opens the first opening 51. The moisture-holding cylinder 5 is set to communicate with the atmospheric pressure. The conductive medium in the moisture-holding cylinder 5 enters the first rod 25 under the action of gravity, flows out from the first opening 51, and enters the soil, achieving the purpose of continuous moisture retention and enabling the electrode 1 to continuously maintain sufficient contact with the soil. When the soil is wet, the water-absorbing substance 58 expands, pushing the detection plate 57 to move, driving the first telescopic rod 54 to extend, and the second spring 53 is compressed. Then, it drives the baffle plate 52 to block the first opening 51 to prevent the leakage of the conductive medium.

[0050] Therefore, the above realizes the automatic detection of whether the soil is dry, ensuring better detection by the electrode 1; when the soil is dry, it can timely and automatically supplement the conductive medium, facilitating better contact between the electrode 1 and the soil, and thus ensuring the accuracy of monitoring; the first rod 25 is threadedly connected to the moisture-holding cylinder 5 and can be removed, and the conductive medium can be added to the first rod 25 and the moisture-holding cylinder 5 accordingly; the elastic shielding film 592 is provided to prevent soil from entering the first plate 24.

[0051] As a specific implementation manner of the present invention, as Figure 2 , Figure 4 , Figure 5 , Figure 7 shown, at the bottom of the inner wall of the first cylinder 22 and corresponding to the position of each digging floor 26, a first groove 6 is opened, the top of each first groove 6 is rotatably connected with a support rod 61, a second groove 62 is opened at the top of each digging floor 26, a sliding block 63 is slidably connected in the second groove 62, and the other end of the support rod 61 is rotatably connected to the side surface of the corresponding sliding block 63;

[0052] Elastic membranes are covered in the first groove 6 and the second groove 62;

[0053] During operation, when the digging floor 26 horizontally digs the ground, a triangle is formed among the side wall of the first cylinder 22, the support rod 61, and the digging floor 26, which has stability and forms a supporting effect to ensure the stability of the digging floor 26 during digging; when the electrode 1 pushes the digging floor 26, the support rod 61 rotates relative to the first cylinder 22 and the sliding block 63, the sliding block 63 slides, and the support rod 61 enters the first groove 6 and the second groove 62 for storage; elastic membranes (not shown in the figure) are covered in the first groove 6 and the second groove 62 to ensure that soil does not enter the first groove 6 and the second groove 62, enabling the support rod 61 to enter the first groove 6 and the second groove 62.

[0054] A method for detecting electromagnetic fluid in a mining area, which uses a mining area electromagnetic fluid detection device as described above, includes the following steps:

[0055] S1: Use a geopotential acquisition instrument to detect the electromagnetic fluid in the mining area; during detection, the electrode 1 needs to be buried.

[0056] S2: During burial, hold the first handle 23 by hand, start the first motor 27, the first motor 27 drives the gear ring 28, drives the first cylinder 22 to rotate, and then the digging floor 26 rotates to break the ground. After breaking the ground, hold the first handle 23 by hand and push the first rod 25 downward. The first rod 25 pushes the electrode 1 into the soil. During this process, the electrode 1 contacts and presses the digging floor 26, and the digging floor 26 rotates and expands outward, enabling the electrode 1 to move out of the first cylinder 22.

[0057] S3: When the electrode 1 enters the soil, the conductive medium also enters the soil and is poured at the position of the electrode 1, ensuring sufficient contact between the electrode 1 and the soil. In addition, if the detection is carried out for a long time and the electrode 1 is continuously inserted into the soil, when the sun shines brightly and the temperature keeps rising, after pouring the conductive medium, the area around the electrode 1 is also likely to change from wet to dry, which is also likely to cause poor contact between the electrode 1 and the soil and affect the detection. Therefore, a moisture-holding cylinder 5 is provided. The inside of the insertion rod 55 is filled with a water-absorbing substance 58. The water-absorbing substance 58 can be substances such as sodium polyacrylate, gelatin, and polyvinyl alcohol, achieving the purpose of detection. When the temperature rises, the water-absorbing substance 58 dehydrates and its volume decreases. Under the extrusion of the second spring 53, the baffle plate 52 opens the first port 51. The conductive medium in the moisture-holding cylinder 5 enters the first rod 25 under the action of gravity, flows out from the first port 51, and enters the soil, achieving the purpose of continuous moisture preservation, so that the electrode 1 and the soil continuously maintain sufficient contact.
