Description

Technical Field

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

[0002] When detecting electromagnetic fluids in mining areas, the geopotential method can be used. The geopotential method is a frequency domain potential depth measurement method that sends alternating currents of different frequencies to the ground through a finite length grounding wire current source, and measures the potential changes in real time within a certain range on the ground. When using the geopotential method for detection, a geopotential collector is required; When using a geopotential collector, electrodes need to be buried, usually in the form of circular wiring and horizontal wiring. Burying electrodes requires a lot of manpower and material resources, especially in arid areas or areas with hard surfaces, where burying electrodes is particularly difficult.

[0003] In view of this, the present invention solves the above technical problems by proposing an electromagnetic fluid detection device and method for mining areas. Summary of the invention

[0004] In order to make up for the shortcomings of the prior art, the electrode can be inserted into the ground without using tools, thereby reducing the difficulty of burying the electrode. The present invention provides a mining area electromagnetic fluid detection device and method.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a mining area electromagnetic fluid detection equipment, including: a geopotential collector, on which electrodes are arranged; the mining area electromagnetic fluid detection equipment also includes: an auxiliary unit, on which an auxiliary unit is arranged, and the auxiliary unit can assist in inserting the electrode into the ground without using tools, thereby reducing the difficulty of burying the electrode.

[0006] Preferably, the auxiliary unit comprises: a No. 1 seat, the bottom of the No. 1 seat is rotatably connected to a No. 1 barrel, the top of the No. 1 seat is fixedly connected to a No. 1 handle, the inside of the No. 1 barrel is slidably connected to a No. 1 plate, the top of the No. 1 plate is fixedly connected to a No. 1 rod, the No. 1 rod penetrates the No. 1 barrel, the No. 1 seat and the No. 1 handle and is exposed at the top of the No. 1 handle, the No. 1 rod is slidably connected to the No. 1 barrel, the No. 1 seat and the No. 1 handle; the bottom of the No. 1 plate is fixedly connected to an electrode; a digging floor, the bottom of the No. 1 barrel is rotatably connected to a plurality of digging floors and a torsion spring is provided at the connecting portion; a No. 1 motor, the No. 1 seat is fixedly connected to a No. 1 motor, the top of the No. 1 barrel and located inside the No. 1 seat is fixedly connected to a gear ring, the output end of the No. 1 motor is fixedly connected to a No. 1 gear, and the No. 1 gear is meshed with the gear ring.

[0007] 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; 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.

[0008] 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; 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.

[0009] 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; 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.

[0010] Preferably, the top of the No. 1 rod is threadedly connected with a moisturizing cylinder, the interior of the moisturizing cylinder is communicated with the interior of the No. 1 rod, and the interior of the moisturizing cylinder is filled with a conductive medium; No. 1 ports are arranged on both sides of the bottom of the No. 1 rod; a shielding plate is slidably connected to the interior of the No. 1 plate corresponding to the position of the No. 1 port, a No. 2 spring is fixedly connected between one side of the shielding plate and the interior of the No. 1 plate, a No. 1 telescopic rod is fixedly connected to the interior of the No. 1 plate on the other side; an insertion rod is slidably connected to the interior of the No. 1 plate corresponding to the position of each No. 1 telescopic rod, and each of the insertion rods is fixedly connected to the interior of the No. 1 plate There is a No. 3 spring, and the plug rod can extend from the inside of the No. 1 plate; the inside of the plug rod is hollow, and a detection plate is slidably connected to the inside of the plug rod, one side of the detection plate is filled with a water-absorbing material and the other side is hollow, and an elastic tube is fixedly connected to the end of the plug rod, and the elastic tube connects the hollow part inside the plug rod with the inside of the No. 1 telescopic rod, and a plurality of water-permeable holes are opened on the side wall of the plug rod at the part of the water-absorbing material; when the water-absorbing material expands, it pushes the detection plate to move, drives the No. 1 telescopic rod to extend, and then drives the shielding plate to block the No. 1 port; an elastic shielding film is fixedly connected between the top of the No. 1 plate and the shielding plate; When the No. 1 plate detaches from the No. 1 tube and enters the soil, the rod is inserted into the soil under the tension of the No. 3 spring. On the one hand, it realizes fixation, which is not conducive to the loosening of the electrode and better detection; on the other hand, when the rod is inserted into the soil, it squeezes the soil and scratches 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, the electrode is always inserted into the soil. If the sun is shining and the temperature is rising, after the conductive medium is poured in, the electrode is also easy to turn from wet to dry, which is also easy to cause poor contact between the electrode and the soil, affecting the detection. Therefore, a moisturizing cylinder is set, and the inside of the rod is filled with a water-absorbing substance. The water-absorbing substance can be sodium polyacrylate, gelatin, polyvinyl alcohol and other substances, which achieves the purpose of detection and the temperature is high. When it rises, the water-absorbing material dehydrates and its volume decreases. Under the compression of the No. 2 spring, the shielding plate opens the No. 1 port, and the conductive medium in the moisturizing cylinder enters the No. 1 rod under the action of gravity, and flows out from the No. 1 port and enters the soil, thereby achieving the purpose of continuous moisturizing, so that the electrode and the soil continue to maintain full contact; when the soil is moist, the water-absorbing material expands, pushing the detection plate to move, driving the No. 1 telescopic rod to extend, and then driving the shielding plate to block the No. 1 port to prevent the conductive medium from leaking out; therefore, the above realizes automatic detection of whether the soil is dry, ensuring better detection of the electrode; the No. 1 rod is threadedly connected to the moisturizing cylinder and can be removed, so that the conductive medium can be added to the No. 1 rod and the moisturizing cylinder; the elastic shielding film is provided to place the soil into the No. 1 plate.

[0011] Preferably, a No. 1 groove is provided at the bottom of the inner wall of the No. 1 barrel corresponding to the position of each excavation floor, and a support rod is rotatably connected to the top of each No. 1 groove. A No. 2 groove is provided at the top of each excavation floor, and a sliding block is slidably connected in the No. 2 groove, and the other end of the support rod is rotatably connected to the corresponding side of the sliding block.

[0012] Preferably, the first groove and the second groove are covered with elastic films; When the excavation floor is digging the ground horizontally, a triangle is formed between the side wall of the No. 1 cylinder, the support rod and the excavation floor, which has stability and forms a supporting effect to ensure the stability of the excavation floor when digging; when the electrode pushes the excavation floor, the support rod rotates relative to the No. 1 cylinder and the sliding block, the sliding block slides, and the support rod enters the No. 1 groove and the No. 2 groove for storage; the No. 1 groove and the No. 2 groove are covered with an elastic membrane (not drawn in the figure) to ensure that soil does not enter the No. 1 groove and the No. 2 groove, so that the support rod can enter the No. 1 groove and the No. 2 groove.

[0013] A method for detecting electromagnetic fluid in a mining area, which is adopted in the above-mentioned electromagnetic fluid detection device in a mining area, comprises the following steps: S1: Use the earth potential collector to detect the electromagnetic fluid in the mining area; during the detection, the electrodes need to be buried; S2: When burying, hold the No. 1 handle and start the No. 1 motor. The No. 1 motor drives the gear ring, which drives the No. 1 barrel to rotate, and then the excavation floor rotates to break the ground. After breaking the ground, hold the No. 1 handle and push the No. 1 rod downward. The No. 1 rod pushes the electrode into the soil. During this process, the electrode contacts and squeezes the excavation floor, and the excavation floor rotates and expands outward, so that the electrode can move out of the No. 1 barrel; S3: When the electrode is inserted into the soil, the conductive medium also enters the soil and is poured into the electrode, ensuring full contact between the electrode and the soil. In addition, if the detection is carried out for a long time, the electrode is always inserted into the soil. If the sun is shining and the temperature is rising, the electrode is also prone to dryness after the conductive medium is poured in, which can also lead to poor contact between the electrode and the soil and affect the detection. Therefore, a moisturizing cylinder is set, and the inside of the rod is filled with a water-absorbing substance. The water-absorbing substance can be sodium polyacrylate, gelatin, polyvinyl alcohol and other substances, so as to achieve the purpose of detection. When the temperature rises, the water-absorbing substance dehydrates and the volume decreases. Under the squeezing of the No. 2 spring, the baffle opens the No. 1 port, and the conductive medium in the moisturizing cylinder enters the No. 1 rod under the action of gravity, and is retained from the No. 1 port and enters the soil, so as to achieve the purpose of continuous moisturizing, so that the electrode and the soil are continuously in full contact.

[0014] The beneficial effects of the present invention are as follows: 1. The electromagnetic fluid detection equipment and method for mining areas described in the present invention, when buried, hold the No. 1 handle and start the No. 1 motor, the No. 1 motor drives the gear ring, drives the No. 1 tube to rotate, and then the excavation floor rotates to break the ground. After breaking the ground, hold the No. 1 handle and push the No. 1 rod downward, the No. 1 rod pushes the electrode into the soil. In this process, the electrode contacts and squeezes the excavation floor, and the excavation floor rotates and expands outward, so that the electrode can move out of the No. 1 tube.

[0015] 2. The electromagnetic fluid detection equipment and method for mining areas described in the present invention, when the electrode is buried in the soil, the conductive medium also enters the soil and is poured into the electrode, thereby ensuring sufficient contact between the electrode and the soil; in addition, if the detection is carried out for a long time, the electrode is always inserted into the soil. If the sun is shining and the temperature is always rising, after the conductive medium is poured in, the electrode is also prone to change from wet to dry, which is also prone to cause poor contact between the electrode and the soil, affecting the detection. Therefore, a moisturizing cylinder is provided, and the inside of the inserted rod is filled with a water-absorbing substance. The water-absorbing substance can be sodium polyacrylate, gelatin, polyvinyl alcohol and other substances, thereby achieving the purpose of detection. When the temperature rises, the water-absorbing substance dehydrates and the volume decreases. Under the squeezing of the No. 2 spring, the baffle opens the No. 1 port, and the conductive medium in the moisturizing cylinder enters the No. 1 rod under the action of gravity, and is retained from the No. 1 port and enters the soil, thereby achieving the purpose of continuous moisturizing, so that the electrode and the soil are continuously kept in sufficient contact.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1 , Figure 3 As shown; The electromagnetic fluid detection equipment for mining areas of the present invention comprises: a ground potential collector, on which an electrode 1 is arranged; the electromagnetic fluid detection equipment for mining areas further comprises: an auxiliary unit 2, on which the electrode 1 is arranged, and the auxiliary unit 2 can assist the electrode 1 in being inserted into the ground without using tools, thereby reducing the difficulty of burying the electrode 1; During operation, when using the earth potential collector, the electrode 1 needs to be buried. Usually, there are ring wiring and horizontal wiring. When burying the electrode 1, manpower and material resources are required, especially for arid areas or areas with hard surface. It is particularly difficult to bury the electrode 1. Therefore, an auxiliary unit 2 is provided on the electrode 1. The auxiliary unit 2 can assist in inserting the electrode 1 into the ground without using tools, thereby reducing the difficulty of burying the electrode 1.

[0020] As a specific embodiment of the present invention, 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; 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; 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.

[0021] 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; 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.

[0022] As a specific embodiment of the present invention, Figure 5 As shown, overflow holes 41 are provided near the bottom of the two side walls of the No. 1 tube 22, and a plurality of connecting platforms 42 are fixedly connected to the position corresponding to the overflow holes 41 on the No. 1 rod 25, and a No. 1 spring 43 is fixedly connected to each connecting platform 42, and a hemispherical block 44 is fixedly connected to the other end of each No. 1 spring 43, and the hemispherical block 44 can be embedded in the overflow hole 41; When the No. 1 rod 25 does not push the electrode 1 into the soil, the overflow hole 41 is located between the piston plate 4 and the No. 1 plate 24. When the No. 1 cylinder 22 rotates, the No. 1 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 of the No. 1 cylinder 22, the overflowed conductive medium wets the soil, making it easy to drill; and 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 44 can be embedded in the overflow hole 41, so that the overflow hole 41 is not easily blocked; at the same time, with the cooperation of the No. 1 spring 43, the hemispherical block 44 intermittently enters the overflow hole 41, which increases the vibration during the drilling of the No. 1 cylinder 22, and it is easier to shake the drilled soil from the borehole wall and the No. 1 cylinder 22 to the bottom of the No. 1 cylinder 22, which is easy to contact with the electrode 1 after the electrode 1 is inserted.

[0023] As a specific embodiment of the present invention, Figure 5 , Figure 8 As shown, the top of the No. 1 rod 25 is threadedly connected with a moisturizing cylinder 5, the interior of the moisturizing cylinder 5 is communicated with the interior of the No. 1 rod 25, and the interior of the moisturizing cylinder 5 is filled with a conductive medium; a No. 1 port 51 is arranged on both sides of the bottom of the No. 1 rod 25; a shielding plate 52 is slidably connected to the interior of the No. 1 plate 24 and corresponds to the position of the No. 1 port 51, and a No. 2 spring 53 is fixedly connected between one side of the shielding plate 52 and the interior of the No. 1 plate 24, and a No. 1 telescopic rod 54 is fixedly connected to the interior of the No. 1 plate 24 on the other side; an insertion rod 55 is slidably connected to the interior of the No. 1 plate 24 and corresponds to the position of each No. 1 telescopic rod 54, and a No. 3 spring 53 is fixedly connected between each insertion rod 55 and the interior of the No. 1 plate 24. 6. The plug rod 55 can extend from the inside of the No. 1 plate 24; the plug rod 55 is hollow inside, and a detection plate 57 is slidably connected inside the plug rod 55. One side of the detection plate 57 is filled with a water-absorbing material 58 and the other side is hollow. An elastic tube 59 is fixedly connected to the end of the plug rod 55. The elastic tube 59 connects the hollow part inside the plug rod 55 with the inside of the No. 1 telescopic rod 54. A plurality of water-permeable holes 591 are opened on the side wall of the plug rod 55 and located at the part of the water-absorbing material 58; when the water-absorbing material 58 expands, it pushes the detection plate 57 to move, drives the No. 1 telescopic rod 54 to extend, and then drives the shielding plate 52 to block the No. 1 port 51; an elastic shielding film 592 is fixedly connected between the top of the No. 1 plate 24 and the shielding plate 52; During operation, when the No. 1 plate 24 separates from the No. 1 tube 22 and enters the soil, the rod 55 is inserted into the soil under the stretching and contraction of the No. 3 spring 56. On the one hand, fixation is achieved, which is not conducive to the loosening of the electrode 1 and better detection is performed; on the other hand, when the rod 55 is inserted into the soil, the soil is squeezed and scratched, causing the soil to fall and squeeze the electrode 1, which is conducive to better contact between the electrode 1 and the soil; in addition, if the detection is carried out for a long time, the electrode 1 is always inserted into the soil. If the sun is shining and the temperature is always rising, after the conductive medium is poured in, the electrode 1 is also easy to change from wet to dry, which is also easy to cause poor contact between the electrode 1 and the soil, affecting the detection. Therefore, a moisturizing tube 5 is provided, and the inside of the rod 55 is filled with a water-absorbing material 58. The water-absorbing material 58 can be sodium polyacrylate. Sodium polyacrylate has the characteristics of swelling upon absorbing water and shrinking upon losing water. Sodium polyacrylate performs best at room temperature and can effectively function at 0 to 80 degrees Celsius. Sodium polyacrylate absorbs After being hydrated, the volume can increase by hundreds of times. Before choosing to install the moisturizing cylinder 5, the sodium polyacrylate can be allowed to absorb enough water in advance and expand its volume sufficiently, so that the No. 1 port 51 remains closed. After the electrode 1 is inserted into the soil, the conductive medium filled inside the No. 1 cylinder 22 and between the piston plate 4 and the No. 1 plate 24 is poured down, and then poured over the insertion rod 55 again, so that the water-absorbing material 58 absorbs water again. When long-term monitoring is required, such as monitoring for several days or months in some cases, in drought conditions, coupled with rising temperatures, the soil becomes drier and drier, which will also cause the sodium polyacrylate to dehydrate. After dehydration, the volume decreases, and under the extrusion of the No. 2 spring 53, the No. 1 telescopic rod 54 is shortened, squeezing the detection plate 57, and then squeezing the water-absorbing material 58, leaving space for the shielding plate 52 to open the No. 1 port 51; when the No. 2 spring 53 is in place, the shielding plate 52 is separated from the No. 1 port 51, that is, the No. 1 port 51 is in an open state; Therefore, the purpose of detection is achieved by adding the water-absorbing substance 58. When the temperature rises, the water-absorbing substance 58 is dehydrated and the volume is reduced. Under the pressure of the No. 2 spring 53, the shielding plate 52 opens the No. 1 port 51, and the moisturizing cylinder 5 is connected to the atmospheric pressure. The conductive medium in the moisturizing cylinder 5 enters the No. 1 rod 25 under the action of gravity, and is retained from the No. 1 port 51 and enters the soil, thereby achieving the purpose of continuous moisturizing, so that the electrode 1 and the soil are continuously in full contact. When the soil is moist, the water-absorbing substance 58 expands, pushes the detection plate 57 to move, drives the No. 1 telescopic rod 54 to extend, and the No. 2 spring 53 is compressed, thereby driving the shielding plate 52 to block the No. 1 port 51 to prevent the conductive medium from leaking out. Therefore, the above realizes automatic detection of whether the soil is dry, ensuring better detection of the electrode 1; when the soil is dry, the conductive medium can be replenished in time and automatically, which is conducive to better contact between the electrode 1 and the soil, thereby ensuring the accuracy of monitoring; the No. 1 rod 25 is threadedly connected to the moisturizing cylinder 5 and can be removed, and the conductive medium can be added to the No. 1 rod 25 and the moisturizing cylinder 5; the elastic shielding film 592 is set to place the soil into the No. 1 plate 24.

[0024] As a specific embodiment of the present invention, Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, a No. 1 groove 6 is provided at the bottom of the inner wall of the No. 1 cylinder 22 and corresponds to the position of each excavation floor 26, and a support rod 61 is rotatably connected to the top of each No. 1 groove 6, and a No. 2 groove 62 is provided at the top of each excavation floor 26, and a sliding block 63 is slidably connected in the No. 2 groove 62, and the other end of the support rod 61 is rotatably connected to the side of the corresponding sliding block 63; The first groove 6 and the second groove 62 are covered with elastic membranes; During operation, when the excavation floor 26 digs the ground horizontally, a triangle is formed between the side wall of the No. 1 cylinder 22, the support rod 61 and the excavation floor 26, which has stability and forms a supporting effect to ensure the stability of the excavation floor 26 when excavating; when the electrode 1 pushes the excavation floor 26, the support rod 61 rotates relative to the No. 1 cylinder 22 and the sliding block 63, the sliding block 63 slides, and the support rod 61 enters the No. 1 groove 6 and the No. 2 groove 62 for storage; the No. 1 groove 6 and the No. 2 groove 62 are covered with an elastic film (not shown in the figure) to ensure that soil does not enter the No. 1 groove 6 and the No. 2 groove 62, so that the support rod 61 can enter the No. 1 groove 6 and the No. 2 groove 62.

[0025] A method for detecting electromagnetic fluid in a mining area, which is used in the above-mentioned electromagnetic fluid detection device in a mining area, comprises the following steps: S1: Use the earth potential collector to detect the electromagnetic fluid in the mining area; during the detection, the electrode 1 needs to be buried; S2: When burying, hold the No. 1 handle 23 and start the No. 1 motor 27. The No. 1 motor 27 drives the gear ring 28, which 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; S3: When the electrode 1 is buried in the soil, the conductive medium also enters the soil and is poured into the electrode 1, ensuring that the electrode 1 is in full contact with the soil. In addition, if the detection is carried out for a long time, the electrode 1 is always inserted into the soil. If the sun is shining brightly and the temperature is rising, after the conductive medium is poured in, the electrode 1 is also prone to dryness, which is also prone to cause poor contact between the electrode 1 and the soil, affecting the detection. Therefore, a moisturizing cylinder 5 is provided, and the insertion rod 55 is filled with a water-absorbing material 58. The water-absorbing material 58 can be sodium polyacrylate, gelatin, polyvinyl alcohol and other materials, so as to achieve the purpose of detection. When the temperature rises, the water-absorbing material 58 is dehydrated and the volume is reduced. Under the squeezing of the No. 2 spring 53, the baffle plate 52 opens the No. 1 port 51, and the conductive medium in the moisturizing cylinder 5 enters the No. 1 rod 25 under the action of gravity, and is retained from the No. 1 port 51 to enter the soil, so as to achieve the purpose of continuous moisturizing, so that the electrode 1 and the soil are continuously kept in full contact.
