Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a portable multi-channel data acquisition instrument for electrical exploration. Background Art

[0002] An electrical prospecting data acquisition system is a geophysical exploration device based on electrical principles. It measures electrical parameters such as resistivity and dielectric constant of underground media to analyze subsurface structure and composition, providing critical data support for resource exploration, engineering planning, and environmental protection. By sending an electric current underground, it captures the influence of geological bodies on the current distribution, thereby inferring the subsurface conditions. Its principle is based on the electrical property differences of rocks (ores). It exploits the differences in conductivity (resistivity, polarizability, dielectric constant, etc.) of different rocks, minerals, or geological bodies, combined with the distribution of electromagnetic fields underground, to infer underground geological structure or resource distribution. In mineral exploration, it can detect metallic ore bodies buried hundreds or even thousands of meters underground. To use it, first arrange the electrodes in the direction of the survey line, insert the electrodes into the ground, and ensure a good ground connection. The spacing between the electrodes is adjusted according to the detection depth (for example, five meters for shallow exploration). Then, connect the multiple electrodes to the main unit with a multi-core cable. After setting the parameters, begin testing.

[0003] High-density electrical methods are generally used in electrical exploration during mineral geological surveys. High-density electrical methods use multi-level electrode rod distances (such as 1 meter, 5 meters, and 10 meters alternately). This layout can synchronously acquire data at different depths, improve vertical resolution, and ensure the regularity and efficiency of data acquisition. However, in existing technologies, the length of the wire is fixed, while the distance between the two electrode rods is not fixed. When the wire length is less than the distance between the two electrode rods, only the detection distance can be changed, which affects the detection results. When the wire length is greater than the distance between the two electrode rods, the wire is prone to irregular winding and knotting, resulting in parasitic inductance in the transmitting circuit, delaying the shutdown time of the transient electromagnetic method, suppressing the induction signal of the early time channel, misjudging the thickness of the shallow high-resistance cover layer, affecting the positioning of the deep ore body, and causing errors in the detected magnetic field signal.

[0004] Therefore, a portable multi-channel data acquisition instrument for electrical exploration is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a portable multi-channel data acquisition instrument for electrical exploration. In order to solve the problem that the length of the wire between the two electrode rods is too long and irregularly coiled during the detection process, which leads to detection errors, a storage shell is provided to coil the wire in sections and regularly inside the storage shell. The wire of the required length is pulled out according to the required measurement length, thereby avoiding the wire between the two electrodes being too long and irregularly coiled.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A portable multi-channel data acquisition instrument for electrical exploration includes a main unit, a conductor and a backpack, and also includes a storage shell, an electrode rod, a storage assembly and a fixing assembly. The storage shell is connected to the backpack, the storage assembly is connected to the inside of the storage shell, the fixing assembly is connected to the inside of the storage shell and to the storage assembly, the conductor is connected to the storage assembly, the electrode rod is connected to the inside of the storage shell through the fixing assembly, the conductor is wound around the outer wall of the storage assembly, and when the conductor is pulled out of the storage shell, the storage assembly is driven to rotate. The fixing assembly limits the electrode rod during wiring.

[0008] In the above scheme, a conductor is divided into multiple sections and carried by multiple storage shells. Each storage box shell carries five meters of conductor, which is the median of the distance between the two electrode rods. When the distance between the electrode rods is greater than five meters, the required length can be met by combining two or more storage shells. When the distance between the electrode rods is less than five meters, the conductor of the required length can be pulled out of the storage shell, thereby reducing the excess conductor length and avoiding the phenomenon of irregular winding of the conductor between the two electrode rods. In addition, when the electrode rod is hammered into the soil, the electrode rod is always kept vertical by fixing the assembly, thereby improving the survey accuracy. At the same time, the depth of the electrode rod nailed into the soil can be limited, so that the nailing depth of each electrode rod is the same, further improving the survey accuracy. After the electrode rod is nailed into the soil, it also fixes the storage shell, thereby improving the stability of the storage shell during wiring.

[0009] Preferably, the storage assembly includes a mounting groove, a clockwork spring, a roller, a hollow shaft and a baffle, the mounting groove is opened at the bottom of the inner wall of the storage shell, the clockwork spring is connected to the inside of the mounting groove, the outer wall of the roller is connected to the clockwork spring, the hollow shaft is connected to the upper end of the roller, one end of the wire passes through the inner wall of the roller and extends to the outside of the hollow shaft, the other end passes through the front side of the storage shell and is movably connected to the front side of the storage shell, the baffle is connected to the inner wall of the storage shell and is located below the hollow shaft, the outer wall of the hollow shaft is connected to a locking assembly, the locking assembly includes a ratchet, a pawl, a limiting edge and a compression spring, the ratchet is connected to the outer wall of the hollow shaft, the limiting edge is connected to the top of the baffle, the pawl is connected to the middle of the limiting edge, and the compression spring is connected to the outer wall of the pawl.

[0010] In the above scheme, the roller is connected to the clockwork spring, and the wire is connected to the outer wall of the roller, thereby forming a tape measure structure. When the wire is pulled out from the front end of the storage shell, it will drive the roller to rotate. When the roller rotates, it will store force on the clockwork spring. When the measurement is completed, the clockwork spring will drive the roller to rotate, thereby automatically retracting the wire, thereby facilitating the recovery of the wire. When the wire is pulled out from the front end of the storage shell, the pawl limits the rotation of the ratchet to limit the rotation of the hollow shaft, thereby preventing the roller from rotating under the elastic force of the clockwork spring to rewind the wire when the detection is not completed, thereby playing a locking role. When the detection is completed, the pawl is pressed to separate the pawl from the ratchet, thereby releasing the locking state of the roller, and the roller rotates under the elastic force of the clockwork spring to rewind the wire.

[0011] Preferably, the fixing assembly includes a connecting groove, a fixing groove, a telescopic plate, a mounting hole and a fixing hole, the connecting groove starts at the top of the storage shell, the fixing groove is opened at the bottom of the storage shell, the telescopic plate is connected to the inside of the connecting groove, the connecting plate is hinged to the upper end of the electrode rod, the fixing groove and the electrode rod are connected, the mounting hole and the fixing hole are both opened at the bottom of the connecting groove, and the fixing hole is located in front of the mounting hole, the inner diameter of the fixing hole is equal to the maximum diameter of the upper electrode and smaller than the outer diameter of the rubber ring.

[0012] In the above scheme, when storing, after the electrode rod is passed through the fixing hole, the lower electrode of the electrode rod is rotated so that the lower electrode is engaged with the fixing groove, so that the electrode rod can be stored as a whole in the card slot of the storage shell, thereby facilitating the carrying of the electrode rod and reducing the space for carrying the electrode rod alone. In addition, the electrode rod and the storage shell correspond one to one, avoiding the situation of carrying too many electrode rods, further reducing the weight of carrying. When arranging the electrode rod, the electrode rod is pulled out of the fixing hole as a whole and then inserted into the fixing hole. After being inserted into the fixing hole, the fixing hole fixes the electrode rod, so it can be carried without manual support. It will maintain a vertical state, thereby improving the safety of arranging the electrode rod, and the inner diameter of the fixing hole is equal to the maximum diameter of the upper electrode, so that the electrode rod will always maintain a vertical state when it is reinstalled, optimizing the arrangement effect of the electrode rod and avoiding the tilt of the electrode rod installation affecting the detection effect. In the process of nailing the electrode rod into the ground, the rubber ring moves downward with the upper electrode. Because the outer diameter of the rubber ring is larger than the inner diameter of the installation hole, when the rubber ring cannot enter the installation hole, when the lower side of the rubber ring contacts the upper side of the storage shell, the electrode rod will be restricted from moving downward, thereby limiting the depth of the electrode rod inserted into the soil.

[0013] Preferably, the electrode rod includes an upper electrode, a connecting hole, a slide plate, a slide groove, a slider, a lower electrode and a protrusion, the upper electrode is hinged to the telescopic plate, the connecting hole is opened at the bottom end of the upper electrode, the slider is connected to the outer wall of the upper electrode, the lower electrode is connected to the lower end of the upper electrode, the slide plate is connected to the upper end of the upper electrode, the slide groove is opened in the middle of the slide plate, the slider is connected to the slide plate, the protrusion is connected to the upper end of the upper electrode, the protrusion is connected to the connecting hole, and the diameter of the upper electrode is larger than the diameter of the lower electrode.

[0014] In the above scheme, when wiring, the lower electrode is taken out from the fixing groove, and the protrusion at the upper end of the lower electrode is engaged with the connecting hole of the upper electrode. Then, the electrode rod after the upper and lower electrodes are engaged is pulled out from the fixing hole as a whole, and then inserted into the mounting hole. Then, the electrode rod as a whole is nailed into the soil, thereby completing the arrangement of the electrode rod.

[0015] Preferably, a rubber ring is connected to the top of the upper electrode, and the outer diameter of the rubber ring is equal to the inner diameter of the mounting hole at the top of the storage shell.

[0016] In the above scheme, when the electrode rod is stored in the storage shell, after the upper electrode is inserted into the mounting hole, the outer diameter of the rubber ring is equal to the inner diameter of the mounting hole, so that the outer wall of the rubber ring fits with the inside of the mounting hole, and the top of the rubber ring is flush with the top of the mounting hole, so that there is no obvious bulge on the storage shell wall after the electrode rod is stored, and the storage shells can fit tightly together, reducing the waste of backpack space.

[0017] Preferably, the outer wall of the mounting hole is connected to a movable ring, the inner diameter of the movable ring is the same as that of the lower electrode, the cross section of the movable ring is set to be T-shaped, the outer wall of the movable ring is connected to a reset spring, the bottom end of the movable ring is set to be a hypotenuse, and is inclined close to the center side.

[0018] In the above scheme, when the electrode rod is arranged through the fixed hole, the lower electrode will pass through the fixed hole of the upper layer and then through the movable ring, and then through the fixed hole of the lower layer. Because the inner diameter of the movable ring is equal to the outer diameter of the lower electrode, and the diameter of the lower electrode is smaller than the diameter of the upper electrode, when the upper electrode moves downward, it will drive the movable ring to move downward and insert into the soil. Therefore, when the wire is pulled up, the movable ring provides support for the storage shell, and the bottom of the movable ring is set as an inclined plate so that the bottom of the movable ring can be more easily inserted into the soil.

[0019] Preferably, the storage shell is internally connected to a wiring assembly including a wiring groove, a connecting ring, a wiring ring, a connecting rod and a mounting plate. The wiring groove is opened on the outer wall of the hollow shaft, the connecting ring is slidingly connected to the wiring groove, the mounting plate is connected to the upper side of the baffle, the connecting rod passes through the mounting plate and is connected to the connecting ring, the wiring ring is connected to the other end of the connecting rod and is coaxial with the fixing hole, and the inner diameter of the wiring ring is equal to the outer diameter of the upper electrode.

[0020] In the above scheme, the connecting ring is connected to the wire through the wiring groove. Because the wiring ring is coaxial with the fixing hole, when the electrode rod passes through the fixing hole, the upper electrode will contact the wiring ring. Therefore, when the electrode rod is arranged, the connection between the electrode rod and the wire is also completed, and the connection between the electrode and the wire is located inside the storage shell, thereby avoiding the connection between the electrode and the wire from getting damp in a humid environment, thereby affecting the detection results.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting up a storage component, the wires are stored in a rectangular storage shell, so that they can be neatly arranged and placed in a backpack, making it convenient to carry the wires. The storage shell can be used to divide a wire into multiple sections for carrying, so that the appropriate length of wire can be pulled out according to the actual measured length between the two electrodes, thereby avoiding the wire being too long and irregularly coiled, forming parasitic inductance that affects the detection results, and the roller and the spring constitute the structure of the tape measure. When the measurement is completed, the spring will drive the roller to rotate and automatically retract the wire, thereby simplifying the winding step. In addition, the storage shell plays a fixing role on the electrode when arranging the electrode, improving the standardization of the electrode installation, and thus improving the accuracy of the detection.

[0023] 2. By setting up a fixing component, the electrode rod is stored as a whole in the card slot of the storage shell using the fixing groove, which makes it convenient to carry the electrode rod and reduces the space for carrying the electrode rod alone. The electrode rod corresponds to the storage shell one by one, avoiding the situation of carrying too many electrode rods, further reducing the weight of carrying. When arranging the electrode rod, the electrode rod is inserted into the fixing hole. The fixing hole fixes the electrode rod so that the electrode rod always remains in a vertical state during the process of being nailed into the ground, avoiding the tilt of the electrode rod installation to affect the detection effect. The fixing hole cooperates with the rubber ring to limit the depth of the electrode rod moving downward into the soil, so that all electrode rods are inserted into the soil to the same depth, thereby improving the accuracy of the detection amount.

[0024] 3. By setting a moving ring, because the inner diameter of the moving ring is smaller than the diameter of the upper electrode, when the upper electrode moves downward, it will drive the moving ring to move downward, so that the lower side of the moving ring is inserted into the soil, providing support for the storage shell when the wire is pulled up. Because the cross section of the moving ring is set to T-shaped, when the moving ring moves down a certain distance, it is blocked by the fixed hole, thereby further limiting the downward movement distance of the electrode rod, so that all electrode rods are inserted into the soil to the same depth, thereby improving the accuracy of the detection amount.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and combine the working state to make its structural features more detailed. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 9 The present invention provides a portable multi-channel data acquisition instrument for electrical prospecting, and the technical solution is as follows:

[0037] A portable multi-channel data acquisition instrument for electrical prospecting, Figure 1 、 Figure 2 and Figure 3 , including a host 10, a wire 1 and a backpack 2, and also including a storage shell 3, an electrode rod 4, a storage component 5 and a fixing component 6. The storage shell 3 is connected to the backpack 2, the storage component 5 is connected to the inside of the storage shell 3, the fixing component 6 is connected to the inside of the storage shell 3 and connected to the storage component 5, the wire 1 is connected to the storage component 5, and the electrode rod 4 is connected to the inside of the storage shell 3 through the fixing component 6. A wire 1 is divided into multiple sections for carrying through multiple storage shells 3. Each storage box shell carries five meters of wire 1, which is the median of the distance between the two electrode rods 4. When the distance between the electrode rods 4 is greater than five meters, the required length can be met by combining two or more storage shells 3. When the distance between the electrode rods 4 is less than five meters, the required length of the wire 1 can be pulled out from the storage shell 3, thereby reducing the excess length of the wire 1 between the two electrode rods 4. The wire 1 is wrapped around the outer wall of the storage component 5. When the wire 1 is pulled out from the storage shell 3, the storage component 5 is driven to rotate. During wiring, the fixing component 6 limits the electrode rod 4. The fixing component 6 keeps the electrode rod 4 vertical at all times, thereby improving the survey accuracy. At the same time, it can also limit the depth of the electrode rod 4 nailed into the soil, so that the nailing depth of each electrode rod 4 is the same, further improving the survey accuracy. After the electrode rod 4 is nailed into the soil, it also fixes the storage shell 3, thereby improving the stability of the storage shell 3 during wiring.

[0038] As an embodiment of the present invention, refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 9The storage assembly 5 includes a mounting groove 501, a spring 502, a roller 503, a hollow shaft 504 and a baffle 505. The mounting groove 501 is opened at the bottom of the inner wall of the storage shell 3, the spring 502 is connected to the inside of the mounting groove 501, the outer wall of the roller 503 is connected to the spring 502, the hollow shaft 504 is connected to the upper end of the roller 503, one end of the wire 1 passes through the inner wall of the roller 503 and extends to the outside of the hollow shaft 504, and the other end passes through the storage shell 3 and is movably connected to the front side of the storage shell 3. The wire 1 is spirally coiled on the outer wall of the roller 503. The baffle 505 is connected to the inner wall of the storage shell 3 and is located below the hollow shaft 504. It is connected to the spring 502 through the roller 503. The wire 1 is then connected to the outer wall of the roller 503, thereby forming a tape measure structure. When the wire 1 is pulled out from the front end of the storage shell 3, it drives the roller 503 to rotate. When the roller 503 rotates, it stores force on the spring 502. When measuring, When the work is completed, the spring 502 will drive the roller 503 to rotate, thereby automatically retracting the wire 1, thereby facilitating the recovery of the wire 1. The outer wall of the hollow shaft 504 is connected to a locking assembly 7, and the locking assembly 7 includes a ratchet 701, a pawl 702, a limit edge 703 and a compression spring 704. The ratchet 701 is connected to the outer wall of the hollow shaft 504, the limit edge 703 is connected to the top of the baffle 505, the pawl 702 is connected to the middle of the limit edge 703, and the compression spring 704 is connected to the outer wall of the pawl 702. The pawl 702 limits the rotation of the ratchet 701, thereby limiting the rotation of the hollow shaft 504, preventing the roller 503 from rotating under the elastic force of the spring 502 to rewind the wire 1 when the detection is not completed, thereby playing a locking role. When the detection is completed, the pawl 702 is pressed to separate the pawl 702 from the ratchet 701, thereby releasing the locking state of the roller 503, and the roller 503 rotates under the elastic force of the spring 502 to rewind the wire 1.

[0039] As an embodiment of the present invention, refer to Figure 2 and Figure 4The fixing assembly 6 includes a connecting groove 601, a fixing groove 602, a telescopic plate 603, a mounting hole 604 and a fixing hole 605. The connecting groove 601 starts at the top of the storage shell 3, and the fixing groove 602 is opened at the bottom of the storage shell 3. The telescopic plate 603 is connected to the inside of the connecting groove 601. The connecting plate is hinged to the upper end of the electrode rod 4. The fixing groove 602 is connected to the electrode rod 4. The mounting hole 604 and the fixing hole 605 are both opened at the bottom of the connecting groove 601, and the fixing hole 605 is located in front of the mounting hole 604. When storing, the electrode After the electrode rod 4 passes through the fixing hole 605, the lower electrode 406 of the electrode rod 4 is rotated so that the lower electrode 406 is engaged with the fixing groove 602, and the electrode rod 4 can be stored in the slot of the storage shell 3 as a whole, thereby facilitating the carrying of the electrode rod 4 and reducing the space required to carry the electrode rod 4 alone. In addition, the electrode rod 4 corresponds to the storage shell 3 one by one, avoiding the situation where too many electrode rods 4 are carried, further reducing the weight of the carrying. When arranging the electrode rod 4, the electrode rod 4 is pulled out of the fixing hole 605 as a whole, and then inserted into the fixing hole 605. After being inserted into the fixing hole 605, the electrode rod 4 is stored in the slot of the storage shell 3. The fixing hole 605 plays a role in fixing the electrode rod 4, so it can be kept in a vertical state without the support of hands, thereby improving the safety of arranging the electrode rod 4, and the inner diameter of the fixing hole 605 is equal to the maximum diameter of the upper electrode 401 so that the electrode rod 4 can always be kept in a vertical state when it is installed, optimizing the arrangement effect of the electrode rod 4, and avoiding the electrode rod 4 being installed tilted to affect the detection effect. The inner diameter of the fixing hole 605 is equal to the maximum diameter of the upper electrode 401 and is smaller than the outer diameter of the rubber ring 408. In the process of nailing the electrode rod 4 into the ground, the rubber ring 4 08 moves downward with the upper electrode 401. Because the outer diameter of the rubber ring 408 is larger than the inner diameter of the mounting hole 604, when the rubber ring 408 cannot enter the mounting hole 604, when the lower side of the rubber ring 408 contacts the upper side of the storage shell 3, the electrode rod 4 will be restricted from moving downward, thereby limiting the depth of the electrode rod 4 inserted into the soil. In addition, a rubber pad can be connected to the bottom of the storage shell 3. In an environment where the ground is uneven, the storage shell 3 is kept in a horizontal state through the deformation of the rubber pad, thereby avoiding affecting the insertion depth of the electrode rod 4 due to the uneven ground.

[0040] As an embodiment of the present invention, refer to Figure 6The electrode rod 4 includes an upper electrode 401, a connecting hole 402, a slide plate 403, a chute 404, a slider 405, a lower electrode 406 and a protrusion 407. The upper electrode 401 is hinged to the telescopic plate 603. The connecting hole 402 is opened at the bottom of the upper electrode 401. The slider 405 is connected to the outer wall of the upper electrode 401. The lower electrode 406 is connected to the lower end of the upper electrode 401. The slide plate 403 is connected to the upper end of the upper electrode 401. The chute 404 is opened in the middle of the slide plate 403. The slider 405 is connected to the slide plate 403. The protrusion Block 407 is connected to the upper end of the upper electrode 401, and the protrusion 407 is connected to the connecting hole 402. The diameter of the upper electrode 401 is larger than the diameter of the lower electrode 406. When wiring, the lower electrode 406 is taken out from the fixing groove 602, and the protrusion 407 at the upper end of the lower electrode 406 is engaged with the connecting hole 402 of the upper electrode 401. Then, the electrode rod 4 after the upper electrode 401 and the lower electrode 406 are engaged is pulled out from the fixing hole 605 as a whole, and then inserted into the mounting hole 604, and then the electrode rod 4 is nailed into the soil as a whole, thereby completing the arrangement of the electrode rod 4.

[0041] As an embodiment of the present invention, refer to Figure 2 、 Figure 4 and Figure 6 A rubber ring 408 is connected to the top of the upper electrode 401. The outer diameter of the rubber ring 408 is equal to the inner diameter of the mounting hole 604 at the top of the storage shell 3. Therefore, when the electrode rod 4 is stored in the storage shell 3, the outer wall of the rubber ring 408 fits with the inside of the mounting hole 604, and the top of the rubber ring 408 is flush with the top of the mounting hole 604, so that there is no obvious bulge on the wall of the storage shell 3 after the electrode rod 4 is stored, and the storage shells 3 can fit tightly together, reducing the waste of space in the backpack 2.

[0042] As an embodiment of the present invention, refer to Figure 2 and Figure 8 , the outer wall of the mounting hole 604 is connected with a movable ring 8, the inner diameter of the movable ring is the same as that of the lower electrode 406, and the cross-section of the movable ring 8 is set to T-shaped. When the electrode rod 4 is passed through the fixed hole 605 to arrange the electrode rod 4, the lower electrode 406 will pass through the upper fixed hole 605 and then through the movable ring 8, and then through the lower fixed hole 605. Because the inner diameter of the movable ring 8 is equal to the outer diameter of the lower electrode 406, and the diameter of the lower electrode 406 is smaller than the diameter of the upper electrode 401, when the upper electrode 401 moves downward, it will drive the movable ring 8 to move downward and insert into the soil, so that when the wire 1 is pulled up, the movable ring 8 provides support for the storage shell 3, thereby improving the stability of the storage shell 3 during wiring. The outer wall of the movable ring 8 is connected with a reset spring 9, and the bottom end of the movable ring 8 is set as a bevel and tilted close to the center, so that the bottom of the movable ring 8 can be more easily inserted into the soil.

[0043] As an embodiment of the present invention, refer to Figure 2 and Figure 7 The storage shell 3 is internally connected with a connection assembly 11 including a wiring groove 1101, a connecting ring 1102, a wiring ring 1103, a connecting rod 1104 and a mounting plate 1105. The wiring groove 1101 is opened on the outer wall of the hollow shaft 504, the connecting ring 1102 is slidably connected to the wiring groove 1101, the mounting plate 1105 is connected to the upper side of the baffle 505, the connecting rod 1104 passes through the mounting plate 1105 and is connected to the connecting ring 1102, the wiring The ring 1103 is connected to the other end of the connecting rod 1104 and is coaxial with the fixing hole 605. The inner diameter of the connecting ring 1103 is equal to the outer diameter of the upper electrode 401. The connecting ring 1102 is connected to the wire 1 through the connecting groove 1101. Because the connecting ring 1103 is coaxial with the fixing hole 605, when the electrode rod 4 passes through the fixing port, the upper electrode 401 will contact the connecting ring 1103. Therefore, when the electrode rod 4 is arranged, the connection between the electrode rod 4 and the wire 1 is also completed.

[0044] Working Principle: During mineral geological surveys, the specified length of the wire 1 is pulled out from the storage shell 3 to solve the problem of irregular winding of the wire 1 between the two electrode rods 4, which may cause errors in detection. The storage assembly 5 inside the storage shell 3 also speeds up the wiring and winding speeds.

[0045] Specifically: when wiring, first rotate the lower electrode 406 of the first storage shell 3 out of the fixing groove 602, then rotate the lower electrode 406 so that the lower electrode 406 is coaxial with the upper electrode 401, and then push the lower electrode 406 upward so that the protrusion 407 at the upper end of the lower electrode 406 is engaged with the connecting hole 402 of the upper electrode 401, and then the electrode rod 4 formed after the upper electrode 401 and the lower electrode 406 are connected is pulled out from the fixing hole 605 as a whole, and then inserted into the mounting hole 604, and then the electrode rod 4 is nailed into the soil as a whole, thereby completing the arrangement of the first electrode rod 4. When the electrode rod 4 is nailed into the soil, the upper electrode 401 will be connected to the wiring ring 1103, thereby completing the connection between the electrode rod 4 and the wire 1, thereby simplifying the wiring steps, and also driving the movable ring 8 to move downward and insert into the soil, so that when the wire 1 is pulled up, the movable ring 8 is The storage shell 3 provides a supporting force to improve the stability of the storage shell 3 when the wire 1 is stretched, and then the moving wire 1 is pulled out from the front end of the storage shell 3. When the wire 1 is pulled out from the inside of the storage shell 3, it will drive the roller 503 to rotate and put the spring spring 502 in a charging state. Because the hollow shaft 504 is fixedly connected to the roller 503, the pawl 702 engages with the ratchet 701 to prevent the hollow shaft 504 from rotating, thereby preventing the roller 503 from rotating, thereby locking the roller 503. After the wire 1 is stretched to the installation position of the next electrode rod 4, the stretched end of the wire 1 is connected to the wire 1 at the top of the next storage shell 3 through the connector of the existing technology, thereby completing the docking between the two sections of the wire 1, and then repeating the previous electrode rod 4 arrangement steps until all electrode rods 4 are installed, and then the wire 1 inside the last storage shell 3 is connected to the host 10.

[0046] When winding the wire: When the detection is completed, pull the electrode rod 4 out of the soil, then pull the electrode rod 4 out of the fixing hole 605, and then insert it into the installation hole 604, then pull down the lower electrode 406 to separate the protrusion 407 at the upper end of the lower electrode 406 from the connecting hole 402 of the upper electrode 401, and then rotate the lower electrode 406 to make the lower electrode 406 rotate around the slider 405 through the slide groove 404, and install the lower electrode 406 in the fixing groove 602, then separate the end of the wire 1 from the storage shell 3 connected to it, and then press the pawl 702 to separate the pawl 702 from the ratchet 701, release the lock on the hollow shaft 504, and make the roller 503 reverse under the elastic force of the spring 502, thereby winding the wire 1 back into the storage shell 3, thereby facilitating the wire recycling.
