Description

Technical Field

[0001] This utility model relates to the field of geophysical electrical exploration equipment, specifically to an auxiliary device for burying non-polarized electrodes. Background Technology

[0002] Non-polarized electrodes, also known as depolarized electrodes or commonly referred to as "electrode tanks," are key components of observation devices in electrical exploration. Properly installing non-polarized electrodes is one of the effective means to extend their service life and plays a decisive role in the acquisition of electrical exploration observation data.

[0003] According to operating procedures, in electrical resistivity tomography (OTT) with long durations and weak signals, the electrode pit depth needs to be at least 30cm to eliminate the influence of surface stray current and voltage. In actual operation, depending on the actual conditions of the surrounding environment of the exploration point, the depth of the electrode pit varies from 1m to 1.5m. In geoelectric field observation, it is even necessary to use a drilling rig to drill deep holes of about 7-14m in depth and about 60cm in diameter as electrode pits. Due to the large depth of the electrode pit and the small diameter of only 60cm, the staff cannot go down to work. They can only slowly lower the non-polarized electrode along the edge of the electrode pit, backfill it with soil, and complete the installation work.

[0004] Currently, there are very few methods for correcting the position of electrodes during installation. When the depth of the electrode pit exceeds the length of a person's arm, workers can only hold the cable by hand and slowly lower the electrode along the edge of the pit. This cannot guarantee that the electrode is in a relatively humid environment, nor can the underground burial environment of the electrode be prepared, thus failing to guarantee the service life of the electrode and obtain reliable observation data.

[0005] In summary, there is an urgent need for an auxiliary device for burying non-polarized electrodes, which can be used to prepare the burial environment of the electrodes and correct the position of the electrodes to ensure that the bottom of the electrodes is in complete contact with the ground. Utility Model Content

[0006] In view of this, the present invention provides an auxiliary device for embedding non-polarized electrodes to solve the defects of the prior art.

[0007] In the first aspect, this utility model provides an auxiliary device for embedding non-polarized electrodes, including a positioning claw, a connecting rod, a damping hinge shaft, and an extension rod; The bottom of the connecting rod is connected to the middle position of the upper surface of the positioning claw via a damping hinge shaft, so that the positioning claw can stay at any angle relative to the connecting rod. The top end of the connecting rod is provided with a threaded interface, which is connected to the extension rod by threads.

[0008] In one possible implementation, the positioning claw is a semi-circular annular plate structure with an outer diameter that is the same as the radius of the bottom of the non-polarized electrode; when the positioning claw rotates to the same plane as the connecting rod, the extension line of the connecting rod passes through the center of the positioning claw.

[0009] In one possible implementation, the end of the positioning claw is tightened to form a claw tip.

[0010] In one possible implementation, the non-polarized electrode embedding auxiliary device further includes a crescent plate, which is detachably fixed to the lower surface of the positioning claw.

[0011] In one possible implementation, the crescent plate is an irregular shape that is half semicircular and half arc-shaped.

[0012] In one possible implementation, the radius of the semicircular portion of the crescent plate is equal to the outer diameter of the positioning claw, and several screw holes are provided on the semicircular portion of the crescent plate corresponding to the position of the positioning claw, so that the crescent plate is installed on the lower surface of the positioning claw by screws.

[0013] In one possible implementation, a countersunk nut hole is provided around the screw hole on the lower surface of the crescent plate.

[0014] In one possible implementation, the upper surface of the positioning claw is provided with friction strips.

[0017] Secondly, all components of the non-polarized electrode embedding auxiliary device of this utility model are detachable and installable through threads, which facilitates carrying and assembly in the field.

Detailed Implementation

[0022] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0024] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0025] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0026] See Figure 1This is a schematic diagram of the overall structure of an auxiliary device for embedding a non-polarized electrode, provided by an embodiment of this utility model. Figure 1 As shown, an auxiliary device for embedding a non-polarized electrode includes a working part 1 and an extension rod 2.

[0027] The working part 1 includes an auxiliary component 11, a connecting rod 12, and a damping hinge shaft 13.

[0028] The auxiliary component includes a positioning claw 111, which is a semi-circular annular sheet structure with an outer diameter that is the same as the radius of the bottom of the non-polarized electrode.

[0029] The bottom of the connecting rod 12 is connected to the middle position of the upper surface of the positioning claw 111 through the damping hinge shaft 13, so that the positioning claw 111 can still stay at any angle relative to the connecting rod 12 while supporting the weight of the non-polarized electrode. When the positioning claw 111 rotates to the same plane as the connecting rod 12, the extension line of the connecting rod 12 passes through the center of the positioning claw 111.

[0030] It should be noted that the damping hinge shaft in this embodiment is existing technology. For example, the damping hinge shaft includes a fastening screw, a lock nut, and damping washers. A hinge seat is provided on the connecting rod 12, and a hinge hole is provided at the middle position of the upper surface of the positioning claw 111. The hinge hole is aligned and connected with the through hole on the hinge seat to form a channel. A damping washer is provided at each end of the channel. The fastening screw passes through the channel and the two damping washers respectively and is connected to the lock nut. Adjusting the lock nut and the fastening screw to a suitable tightness allows the positioning claw 111 to remain at any angle relative to the connecting rod 12 while supporting the weight of the non-polarized electrode. As another example, the damping hinge shaft consists of a set of male and female locking screws.

[0031] The end of the positioning claw 111 is tightened to form a claw tip 112, which is used to stir the soil at the burial location before burying the non-polarized electrode.

[0032] The auxiliary component also includes a crescent plate 113, which can be detachably fixed to the lower surface of the positioning claw 111. It is used to clean up stones, grass roots and other debris in the electrode pit and level the soil in the electrode pit to ensure that the bottom of the electrode is in complete contact with the ground.

[0033] See Figure 2 This is a bottom view of the crescent-shaped plate provided in an embodiment of this utility model. Figure 2 As shown, the crescent plate 113 is an irregular shape that is half semicircular and half arc-shaped. The diameter of the semicircular part coincides with the chord of the arc-shaped part and the lengths are equal.

[0034] The radius of the semicircular portion of the crescent plate 113 is equal to the outer diameter of the positioning claw 111, and several screw holes are provided on the semicircular portion of the crescent plate 113 corresponding to the position of the positioning claw 111, so that the crescent plate 113 is installed on the lower surface of the positioning claw 111 by screws.

[0035] Furthermore, a countersunk hole 1131 for nuts is provided around the screw hole on the lower surface of the crescent plate 113. When the crescent plate 113 is installed on the lower surface of the positioning claw 111, the screw nut is screwed into the countersunk hole 1131 to keep the lower surface of the crescent plate flat.

[0036] Furthermore, a friction strip 114 is provided on the upper surface of the positioning claw 111 to increase the friction between the positioning claw 111 and the bottom of the non-polarized electrode, so as to prevent the non-polarized electrode from slipping off the positioning claw when it is placed.

[0037] The top end of the connecting rod 12 is provided with a threaded interface, which can be connected to the extension rod 2 by thread.

[0038] The top of the extension rod 2 is also provided with a threaded interface 21, so that the operator can freely connect the extension rod according to the depth of the electrode pit.

[0039] The non-polarizable electrode embedding auxiliary device described in this embodiment is used as follows: According to the operating procedures, during the installation of the non-polarizable electrode, stones, grass roots, and other debris should first be removed from the electrode pit where the non-polarizable electrode will be placed. At this point, the on-site construction personnel can install the crescent plate 113 onto the bottom of the positioning claw 111 and rotate the damping hinge shaft 13 to make the connecting rod 12 perpendicular to the positioning claw 111. The operating state at this time is as follows: Figure 1 As shown, on-site staff extend the non-polarizable electrode burial auxiliary device into the electrode pit, clean up and remove stones, grass roots and other debris from the bottom of the pit, and use a crescent plate to level the bottom of the electrode pit appropriately.

[0040] According to the operating procedures, before burying the non-polarizable electrode, a certain amount of calcined soil needs to be placed in the electrode pit, followed by the pouring of an appropriate amount of brine. During on-site construction, after placing the calcined soil in the electrode pit and pouring in the brine, the on-site construction personnel can remove the crescent plate and rotate the damping hinge shaft 13 to bring the connecting rod 12 and the positioning claw 111 to the same plane. (See [reference]). Figure 3 This is a schematic diagram illustrating the usage state of an auxiliary device for embedding a non-polarized electrode according to an embodiment of the present invention. The usage state at this time is as follows: Figure 3 As shown, on-site workers used a positioning claw to mix the fertile soil and salt water into a paste-like slurry.

[0041] According to the operating procedures, when placing the non-polarizable electrode into the electrode pit, it is necessary to ensure that the bottom of the electrode is in complete contact with the ground. After mixing the calcined soil and brine into a paste-like slurry, the on-site construction personnel can rotate the damping hinge shaft 13 to bring the connecting rod 12 and the positioning claw 111 back into a vertical position. See [link / reference needed]. Figure 4 This is a schematic diagram illustrating the usage state of an auxiliary device for embedding a non-polarized electrode according to an embodiment of the present invention. The usage state at this time is as follows: Figure 4 As shown, the on-site staff placed the non-polarized electrode onto the positioning claw 111 and slowly lowered it vertically into the mud in the electrode pit along the pit wall to avoid damaging the cable by holding it while placing the electrode. Then, the positioning claw was pulled out from the bottom of the non-polarized electrode and placed on top of the non-polarized electrode, so that the cable at the top of the non-polarized electrode extended from between the two positioning claws. A vertical force was applied against the top of the non-polarized electrode to press it vertically into the mud, ensuring that the bottom of the electrode was in complete contact with the ground.

[0042] Repeat the above process until all non-polarized electrodes are buried. Let the non-polarized electrodes stand for a period of time until the natural potential stabilizes before taking measurements.

[0043] It should be noted that conventional designs / modifications made by those skilled in the art to achieve the technical effects of this utility model based on common knowledge in the field are all conventional technical means in the field, and will not be described in detail here.

[0044] The above description is merely a specific embodiment of this application. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application. The protection scope of this application should be determined by the protection scope of the claims.
