Description

Technical Field

[0001] The present invention relates to the field of conductive technology, and in particular to a grounding rod that is convenient for horizontal or vertical arrangement. Background Art

[0002] A grounding rod refers to a metal rod used in electrical engineering to safely conduct electric current into the earth. It is one of the most basic and critical components of the grounding system. Its core function is to provide a low-resistance path so that fault current, lightning current, or static electricity can be safely and quickly discharged into the earth, thereby protecting people or equipment.

[0003] Existing ground rods are straight rods that are inserted vertically into the ground by hammering. In areas where vertical penetration is difficult, such as rocks, trenches are usually dug for horizontal burial. However, during the trench excavation process, some obstacles in the trench are difficult to break through, and straight ground rods cannot bypass obstacles, so another location needs to be selected for re-digging of the trench, which is more troublesome and time-consuming. If soft grounding tape is carried for laying, it is inconvenient to insert the soft grounding tape into the ground to the predetermined depth when vertical arrangement is required. In addition, carrying different types of grounding tape outdoors is also more physically demanding and consumes backpack space. For this reason, we propose a ground rod that is convenient for horizontal or vertical arrangement. Summary of the Invention

[0004] The object of the present invention is to provide a grounding rod that is convenient for horizontal or vertical arrangement, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a grounding rod that is convenient for horizontal or vertical arrangement, comprising:

[0006] Binding posts;

[0007] Grounding rods are provided at least two times along the axis of the terminal post, and two adjacent grounding rods are connected by interference fit, and a flexible conductive member is provided between the terminal post and the grounding rod, and the side wall of the grounding rod has a plane;

[0008] The tip is fixed to one end of the last ground rod arranged axially;

[0009] Wherein, the flexible conductive member includes a conductive wire and a connecting post, the conductive wire and the connecting post are arranged side by side, and the connecting post is connected to the grounding rod.

[0010] Preferably, the conductive wire includes a copper conductor and a steel wire rope, the copper conductor is provided at least at two locations along the circumference of the steel wire rope, and the copper conductor is spirally wound along the axial direction of the steel wire rope.

[0011] Preferably, the grounding rod comprises a rod body, a connecting hole and a frustum, wherein the frustum is fixed to one end of the rod body, the connecting hole is opened at the other end of the rod body, and the height of the connecting hole is greater than the height of the frustum.

[0012] Preferably, a first connecting groove cooperating with the connecting column is opened at one end of the inner side of the connecting hole, and a second connecting groove is opened at the inner side of the truncated cone.

[0013] Preferably, the first connecting groove and the second connecting groove are both fitted with the connecting column by interference fit or threaded fit.

[0014] Preferably, a notch is provided on one side wall of the truncated cone, and the notch is communicated with the interior of the second connecting groove.

[0015] Preferably, the outer diameter of the frustum decreases along the height direction, and the rod body and the frustum are an integrally formed structure.

[0016] Preferably, an edge groove is formed on one end surface of the connecting column.

[0017] Preferably, a pin block is fixed on the plane, and one end of the pin block away from the plane has a chamfer, and a connecting groove is formed on the lower surface of the grounding rod corresponding to the pin block.

[0018] Preferably, a conductive plate is provided on one side wall of the terminal post, and a terminal bolt is provided on the conductive plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention is provided with a rod body, a conductive wire and a connecting column, thereby avoiding the problem that the traditional grounding rod is a straight rod body, which is not convenient for bypassing obstacles when arranged horizontally, and the soft grounding strip is not convenient for vertically inserting into the ground to a predetermined depth. The present invention can flexibly transform between a rigid or flexible state, so that it is convenient for horizontal or vertical arrangement during installation, and can avoid obstacles in the excavated trench when arranged horizontally, thereby increasing the convenience of device installation and reducing the inconvenience of users having to carry different types of grounding. The device can also be easily wound into a disk as needed when carried, thereby improving the convenience of carrying. In addition, the conductive wire and the rod body are detachably connected through the connecting column, which is convenient for later maintenance and replacement of one of the multiple grounding rods, so as to avoid the waste caused by the entire rod being scrapped after a section of the long rod body is damaged.

[0021] (2) By providing a plane, chamfer and pin block, the cross-section of the traditional grounding rod is avoided to be circular, with a small connection area at the contact point and a large resistance. The present device can make multiple grounding rods in close contact through the plane, ensuring a good conductive area at the contact point, improving the grounding conductive effect, reducing the resistance value, and also facilitating the connection of multiple grounding rods to form a whole, so that multiple grounding rods can be inserted into the ground at the same time during a single hammering. Multiple grounding rods that are closely attached have lower resistance than a single grounding rod, and occupy a smaller area than multiple grounding rods that are dispersed, which is conducive to arrangement in a space-constrained environment.

[0022] (3) By providing flexible conductive parts, cones, notches and connection holes, the traditional grounding rods are mostly straight long rods, which have a large aspect ratio during installation and are prone to bending and tilting, affecting the depth of insertion into the ground. The present device can convert a long rod into multiple short rods during hammering installation, reducing the length between the top of the rod and the ground during hammering, thereby hammering the short rods into the ground one by one, reducing the bending and tilting of the rod and improving the installation effect.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0035] See also Figures 1-10 The present invention provides a technical solution: a grounding rod that is convenient for horizontal or vertical arrangement, comprising:

[0036] Terminal 2;

[0037] Grounding rods 1 are provided at least two times along the axis of the terminal 2, and two adjacent grounding rods 1 are connected by interference fit, and a flexible conductive member 5 is provided between the terminal 2 and the grounding rod 1, and the side wall of the grounding rod 1 has a flat surface 6;

[0038] like Figure 1 As shown, when the ground rod is vertically inserted into the ground, two ground rods 1 are connected to each other to form a straight rod body, as shown in FIG. Figure 8 As shown, when laying horizontally, the two ground rods 1 can be made not to touch each other and then connected by a flexible conductive member 5, so that the flexible conductive member 5 is bent to bypass obstacles inside the horizontal excavation trench, so as to avoid the straight rod body being unable to bypass the obstacle and the need to dig a new trench without obstacles;

[0039] The tip 4 is fixed to one end of the axially arranged last ground rod 1;

[0040] The flexible conductive member 5 includes a conductive wire 51 and a connecting post 52 . The conductive wire 51 and the connecting post 52 are arranged side by side, and the connecting post 52 is connected to the ground rod 1 .

[0041] like Figure 1-3 As shown, the conductive wire 51 facilitates bypassing obstacles inside the transverse excavated trench, and at the same time ensures that adjacent grounding rods 1 are electrically connected to each other through the conductive wire 51. In addition, when not in use, multiple grounding rods 1 can be bent and wound through the conductive wire 51 to form a disk to improve portability.

[0042] Preferably, the conductive wire 51 includes a copper conductor 511 and a steel wire rope 512 , the copper conductor 511 is provided at least two locations along the circumference of the steel wire rope 512 , and the copper conductor 511 is spirally wound along the axial direction of the steel wire rope 512 ;

[0043] like Figure 4 As shown, it is convenient to pass the copper wire 511 to achieve a good conductive effect, and the steel wire rope 512 is used to improve the strength to prevent the copper wire 511 from being pulled and damaged.

[0044] Preferably, the ground rod 1 includes a rod body 101, a connecting hole 102 and a truncated cone 104. The truncated cone 104 is fixed to one end of the rod body 101, and the connecting hole 102 is opened at the other end of the rod body 101. The height of the connecting hole 102 is greater than the height of the truncated cone 104.

[0045] like Figure 5 As shown, it is convenient to quickly connect multiple rods 101 through the connecting holes 102 and the truncated cone 104 to form a straight rod, so that it is convenient to vertically insert it into the ground at a certain depth, and the height of the connecting hole 102 is greater than the height of the truncated cone 104, which is conducive to forming a cavity between the two. The flexible conductive member 5 is accommodated by the cavity to avoid damage to the flexible conductive member 5 caused by contact with the outside or damage caused by squeezing by the truncated cone 104, thereby improving the safety of the flexible conductive member 5.

[0046] Preferably, a first connecting groove 103 cooperating with the connecting column 52 is formed at one end of the inner side of the connecting hole 102 , and a second connecting groove is formed at the inner side of the truncated cone 104 .

[0047] like Figure 5 As shown, the connecting posts 52 at the two ends of the conductive wire 51 are quickly connected and matched with the two adjacent rods 101 to achieve grounding and conduction or avoid separation of the two rods 101. Later, by pulling out the connecting post 52 from the inner sides of the first connecting groove 103 and the second connecting groove, the two rods 101 can be easily separated, thereby maintaining and replacing one of the multiple grounding rods 1, thereby improving maintenance convenience.

[0048] Preferably, the first connecting groove 103 and the second connecting groove are both fitted with the connecting column 52 by interference fit or threaded fit;

[0049] It is convenient to quickly fix the connecting column 52 with the first connecting groove 103 and the second connecting groove, and it is also easy to disassemble and maintain in the later stage.

[0050] Preferably, a notch 105 is formed on one side wall of the truncated cone 104, and the notch 105 is connected to the interior of the second connecting groove;

[0051] like Figure 6As shown, when the ground rod 1 is vertically installed and hammered, the flexible conductive member 5 is pushed into the inner side of the notch 105 to avoid damage to the flexible conductive member 5 when hammering the top of the rod body 101, thereby improving safety during installation.

[0052] Preferably, the outer diameter of the truncated cone 104 decreases along the height direction, and the rod body 101 and the truncated cone 104 are an integrally formed structure;

[0053] like Figure 6 As shown, the design of reducing the height of the cone 104 facilitates the better insertion of the cone 104 into the inner side of the connecting hole 102 when the adjacent rods 101 are connected, and after insertion, the cone 104 has a larger contact area with the connecting hole 102, which facilitates improving the conductive effect. The larger contact area is also beneficial for better dispersion of the hammering force during hammering installation, avoiding local deformation and damage caused by greater hammering intensity.

[0054] Preferably, a groove 53 is formed on one end surface of the connecting column 52;

[0055] When the two connecting posts 52 are threadedly engaged with the first connecting groove 103 and the second connecting groove, the connecting posts 52 can be unscrewed from the grooves to perform maintenance and replacement on one of the multiple grounding rods 1 .

[0056] Preferably, a pin block 72 is fixed on the plane 6, and the end of the pin block 72 away from the plane 6 has a chamfer 71, and a connecting groove is opened on the lower surface of the ground rod 1 corresponding to the pin block 72;

[0057] like Figure 7 As shown, the plane 6 is convenient for increasing the contact area between the rod 101 and the surrounding rods 101, thereby avoiding the problem that the cross-section of the conventional grounding rod 1 is usually circular, and the contact area is small when the connection is released, which affects the conductive effect. Moreover, after the two rods 101 are connected, the pin block 72 cooperates with the connecting groove to effectively avoid relative sliding between the two rods 101. When multiple rods 101 are inserted into the ground by a single hammering, the multiple rods 101 are made to descend at the same time, avoiding the different insertion depths of the rods 101, which affects the grounding effect.

[0058] Preferably, a conductive plate is provided on one side wall of the terminal post 2 , and a terminal bolt 3 is provided on the conductive plate.

[0059] The working principle and use process of the present invention are as follows: when arranged horizontally, a groove is first excavated, and then two adjacent rods 101 can be flexibly connected through the conductive wire 51, and then the conductive wire 51 is bent and adjusted, such as Figure 8 As shown, in order to avoid the immovable obstacles in the trench, a curved path is formed to enable the grounding rod 1 to be better arranged horizontally, avoiding the inconvenience of encountering difficult-to-break obstacles during the trench excavation process and needing to re-select a site for trench excavation.

[0060] When arranged vertically, the tip 4 and the adjacent ground rod 1 are hammered into the ground, and a Figure 10 The bent state shown is used to convert a long grounding rod into multiple short rods 101 to avoid the long rods from bending or tilting during hammer installation, which affects the vertical installation depth. The device can first hammer the lowest grounding rod 1 into the ground, connect the two adjacent rods 101 through the connecting hole 102 and the round table 104, and then hammer another grounding rod 1 into the ground to install multiple grounding rods 1. In addition, when a larger grounding conductive area is required, the adjacent grounding rods 1 can be matched through the chamfer 71 and the pin block 72 to form Figure 9 As shown, the grounding resistance can be reduced. In addition, the structure can also increase the conductive area when arranged horizontally, thereby increasing the practicality of the device.
