[0001] The utility model relates to the technical field of electrical prospecting, in particular to a wiring structure of an electrical prospecting device. Background Art

[0002] Electrical prospecting is an important technical means of geological survey. Based on the differences in electromagnetic and electrochemical properties of various types of rocks or ore bodies in the earth's crust, electrical prospecting aims to find different types of useful mineral deposits, identify geological structures, and solve geological problems by observing and studying the spatial distribution laws and temporal characteristics of artificial or natural electric fields, electromagnetic fields, or electrochemical fields. During electrical prospecting, the remote electrode needs to be electrically connected to the host;

[0003] At present, the electrical connection between the remote electrode and the host is usually achieved by cutting the outer sheath and the insulating sleeve of the remote electrode cable, overlapping the exposed core wire with the wire end of the host cable, and then wrapping the overlapped cable with insulating tape. However, the tape winding efficiency at the cable connection is low, and the tape may be damaged by water infiltration or friction from branches due to being placed in stagnant water or densely wooded areas. If the wrapping is not tight, it is easy to cause leakage, which increases a certain degree of danger and is difficult to meet actual use needs. Therefore, we propose a wiring structure for electrical prospecting equipment to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wiring structure for an electrical prospecting device, which solves the problems of low efficiency of tape winding at cable connections and loose wrapping of the tape, which easily leads to leakage and increases certain risks.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: the wiring structure of the electrical prospecting device includes symmetrically arranged insulating sleeves, and a connecting component is installed between two groups of the insulating sleeves;

The conductive column is plugged into the inside of the conductive sleeve through a snap-fit ​​mechanism, and a silicone sealing ring is provided at the connection between the two groups of insulating sleeves.

[0007] Preferably, the two groups of the extrusion bolts and the conductive sheets correspond to each other. The thread teeth provided on the inner wall of the limit cap are in threaded connection with the thread grooves on the outer surface of the insulating sleeve. An installation hole is formed on the surface of the insulating sleeve close to the extrusion bolt. A sealing threaded sleeve is fixedly installed in the installation hole of the insulating sleeve. The extrusion bolt is in threaded connection with the sealing threaded sleeve on the insulating sleeve.

[0008] Preferably, an arc surface is provided on the outer surface of the conductive sheet to increase the contact area with the inner side wall of the insulating sleeve.

[0009] Preferably, anti-slip grooves are provided on the surface of the conductive sheet.

[0010] Preferably, the extrusion bolt is made of plastic insulating material.

[0011] Preferably, the engaging mechanism includes two groups of lock blocks symmetrically arranged and sliding inside the conductive column, and springs symmetrically arranged and fixed between the lock blocks and the conductive column. A clamping hole adapted to the lock block is formed on the surface of the conductive sleeve.

[0013] Beneficial Effects

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 shown:

[0023] The wiring structure of the electrical prospecting device includes insulating sleeves 1 arranged symmetrically.

[0024] In this implementation scheme: To solve the technical problems existing in this prior art, as disclosed in the background art above, "the exposed core wire and the wire head of the host cable are wound and wrapped with insulating tape for the lapped cable, but the winding efficiency of the tape at the cable connection is low, and the tape may be damaged due to being placed in a waterlogged area or a densely wooded area, being soaked by water or rubbed by tree branches, resulting in incomplete wrapping and easy leakage, increasing a certain degree of danger". In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, the connecting component 2 is added in this application document.

[0025] Furthermore:

[0026] As Figures 1 - 4 shown:

[0027] A connection component 2 is installed between two groups of insulating sleeves 1. The connection component 2 includes conductive sheets 201 fixed to the inner side walls of the insulating sleeves 1, extrusion bolts 207 arranged symmetrically on the insulating sleeves 1, and annular sheets 209 arranged at the two ends of the insulating sleeves 1 away from each other. A limit cap 208 is provided at one end of the insulating sleeve 1 close to the annular sheet 209. An annular sealing ring 210 is arranged between the limit cap 208 and the annular sheet 209. Conductive sleeves 202 and conductive columns 203 are respectively fixed to one side of the two groups of conductive sheets 201 close to each other. The conductive column 203 is inserted into the inside of the conductive sleeve 202 through a clamping mechanism. A silica gel sealing ring sleeve 211 is sleeved at the connection of the two groups of insulating sleeves 1. The two groups of extrusion bolts 207 correspond to the conductive sheets 201. The thread teeth arranged on the inner wall of the limit cap 208 are threadedly connected with the thread grooves on the outer surface of the insulating sleeve 1. An installation hole is opened on the surface of the insulating sleeve 1 close to one side of the extrusion bolt 207. A sealed thread sleeve is fixedly installed in the installation hole of the insulating sleeve 1. The extrusion bolt 207 is threadedly connected with the sealed thread sleeve on the insulating sleeve 1.

[0028] In this implementation: When the wiring structure of this electrical prospecting device is in use, when connecting the remote electrode cable and the host cable, first, the two groups of limit caps 208 are respectively sleeved on the remote electrode cable and the host cable in sequence. Then, the two groups of annular sealing rings 210 are respectively sleeved on the remote electrode cable and the host cable in sequence. Then, one end of the remote electrode cable is inserted into the inside of the insulating sleeve 1 along the inner hole of the annular sheet 209. Then, one extrusion bolt 207 is rotated to squeeze and fix the insulating layer on the remote electrode cable. Then, the other extrusion bolt 207 is rotated to squeeze and fix the core wire on the remote electrode cable on the surface of the conductive sheet 201. Through this operation, the host cable is installed inside the other group of insulating sleeves 1.

[0029] Then, the annular sealing rings 210 sleeved on the remote electrode cable and the host cable are moved to the position of the annular sheet 209. Then, the limit cap 208 is screwed onto one end of the insulating sleeve 1 through threaded connection. In this process, the annular sealing ring 210 is squeezed. At this time, the seal between the annular sealing ring 210 and the annular sheet 209 is increased. At the same time, the annular sealing ring 210 is tightly sleeved on the remote electrode cable and the host cable to increase its sealing performance. Thus, through the seals at these two places, the seals between the two groups of insulating sleeves 1 and the remote electrode cable and the host cable are realized respectively.

[0030] Subsequently, the conductive post 203 is inserted into the conductive sleeve 202 through the engaging mechanism. When the conductive sleeve 202 and the conductive post 203 are fully inserted, the two insulating sleeves 1 are in contact with each other at this time. Then, the silicone rubber sealing ring sleeve 211 is moved to the connection part of the two insulating sleeves 1, thereby realizing the sealing of the connection part of the two insulating sleeves 1. Since the conductive sheet 201, the conductive sleeve 202, and the conductive post 203 are all made of conductive materials, the power of the host cable is conducted along the conductive sheet 201, the conductive sleeve 202, and the conductive post 203 to the distal electrode cable. Through this operation, the connection efficiency of the two cables is improved, and there is no need to fix them by winding with tape. Through the settings of the annular sealing ring 210 of the insulating sleeve 1 and the silicone rubber sealing ring sleeve 211, the two cables are effectively protected and isolated, the sealing performance of the connection of the two cables is increased, the situation of water ingress or cable exposure resulting in electric leakage is avoided, the risk is reduced to a certain extent, the use effect of this structure is improved, and the actual use requirements are met.

[0031] It should be noted that: the above structure can select different specifications according to different cable diameters for connection and fixation.

[0032] Furthermore;

[0033] In an alternative embodiment, an arc surface is provided on the outer surface of the conductive sheet 201 for increasing the contact area with the inner side wall of the insulating sleeve 1.

[0034] In this embodiment: an arc surface is provided on the outer surface of the conductive sheet 201, increasing the contact area with the inner side wall of the insulating sleeve 1 and improving the fixing effect on the conductive sheet 201.

[0035] Furthermore;

[0036] In an alternative embodiment, anti-slip grooves are provided on the surface of the conductive sheet 201.

[0037] In this embodiment: when the cable is extruded by squeezing the bolt 207, through the anti-slip grooves, the friction between the cable and the conductive sheet 201 is increased, improving the extrusion and fixing effect on the cable.

[0038] Furthermore;

[0039] In an alternative embodiment, the squeezing bolt 207 is made of plastic insulating material.

[0040] In this embodiment: the squeezing bolt 207 is made of plastic insulating material, preventing the electricity conducted by the cable from being conducted through the squeezing bolt 207 and causing danger to personnel, improving the safety guarantee.

[0041] Furthermore;

[0042] In an optional embodiment, the engaging mechanism includes two sets of locking blocks 205 that slide symmetrically inside the conductive post 203 and springs 206 that are fixed symmetrically between the locking blocks 205 and the conductive post 203. Card holes 204 adapted to the locking blocks 205 are provided on the surface of the conductive sleeve 202. The conductive post 203 is stuck in the card holes 204 provided in the conductive sleeve 202 through the locking blocks 205 for connecting and locking the conductive sleeve 202 and the conductive post 203.

[0043] One side of the locking block 205 is designed with an inclined surface structure. A moving groove adapted to the locking block 205 is provided on the surface of the conductive post 203. The locking block 205 and the conductive post 203 are slidably connected through this moving groove.

[0044] In this embodiment: The conductive post 203 is inserted into the conductive sleeve 202 through the engaging mechanism. During this process, the locking block 205 is resisted by the conductive sleeve 202 to squeeze the locking block 205. Since one side of the locking block 205 is designed with an inclined surface, the locking block 205 slides in the moving groove and compresses the spring 206 until the locking block 205 completely moves into the conductive post 203. When the conductive post 203 is completely inserted into the conductive sleeve 202, at this time, the locking block 205 corresponds to the card hole 204, the locking block 205 is not blocked, the spring 206 rebounds, and drives the locking block 205 to be inserted into the card hole 204 provided in the conductive sleeve 202 to complete the locking between the conductive post 203 and the conductive sleeve 202.

[0045] Working principle and usage process of the present utility model: When the wiring structure of this electrical prospecting device is in use and the remote electrode cable and the host cable are connected, first, two sets of limit caps 208 are respectively sleeved on the remote electrode cable and the host cable in sequence. Subsequently, two sets of annular sealing rings 210 are respectively sleeved on the remote electrode cable and the host cable in sequence. Then, one end of the remote electrode cable is inserted into the interior of the insulating sleeve 1 along the inner hole of the annular piece 209. Subsequently, one extrusion bolt 207 is rotated to extrude and fix the insulating layer on the remote electrode cable. Then, the other extrusion bolt 207 is rotated to extrude and fix the core wire on the remote electrode cable on the surface of the conductive piece 201. Through this operation, the host cable is installed inside another set of insulating sleeves 1. Subsequently, the annular sealing rings 210 sleeved on the remote electrode cable and the host cable are moved to the position of the annular piece 209. Then, the limit cap 208 is screwed onto one end of the insulating sleeve 1 through threaded connection. During this process, the annular sealing ring 210 is extruded, increasing the seal between the annular sealing ring 210 and the annular piece 209. At the same time, the annular sealing ring 210 is tightly sleeved on the remote electrode cable and the host cable to increase its sealing performance. Thus, through the sealing at these two places, the sealing between the two sets of insulating sleeves 1 and the remote electrode cable and the host cable respectively is achieved. Subsequently, the conductive column 203 is inserted into the conductive sleeve 202 through the engaging mechanism. During this process, the locking block 205 is resisted by the conductive sleeve 202 to extrude the locking block 205. Since one side of the locking block 205 is designed with an inclined surface, the locking block 205 slides in the moving groove and compresses the spring 206 until the locking block 205 completely moves into the conductive column 203. When the conductive column 203 is completely inserted into the conductive sleeve 202, at this time, the locking block 205 corresponds to the card hole 204, and the locking block 205 is not blocked. The spring 206 rebounds and drives the locking block 205 to insert into the card hole 204 opened in the conductive sleeve 202, completing the locking between the conductive column 203 and the conductive sleeve 202. When the conductive sleeve 202 and the conductive column 203 are completely inserted, at this time, the two sets of insulating sleeves 1 are in contact with each other. Subsequently, the silicone sealing ring sleeve 211 is moved to the connection position of the two sets of insulating sleeves 1, thus realizing the sealing at the connection of the two sets of insulating sleeves 1. Since the conductive piece 201, the conductive sleeve 202, and the conductive column 203 are all made of conductive materials, at this time, the power of the host cable is conducted to the remote electrode cable along the conductive piece 201, the conductive sleeve 202, and the conductive column 203. Through this operation, the connection efficiency of the two sets of cables is improved, and there is no need to fix them by winding with tape. Through the settings of the insulating sleeve 1, the annular sealing ring 210, and the silicone sealing ring sleeve 211, the two sets of cables are effectively protected and isolated, increasing the sealing performance of the connection of the two sets of cables, avoiding water ingress or cable exposure resulting in electric leakage, reducing a certain degree of danger, improving the usage effect of this structure, and meeting the actual usage requirements.
