Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction tools, in particular to a grounding rod for winter maintenance operations. Background Technique

[0002] In electric power construction and maintenance work, in order to ensure the safety of construction and maintenance, the installation of grounding wires is an essential and important work item, which is used to conduct current into the ground to protect personnel when the equipment leaks electricity. When there is no ready-made grounding device, most of the time, a grounding rod is used to drive into the soil on the spot for grounding.

[0003] Most of the existing grounding rods are steel rods with a pointed head at one end. Tools such as hammers are used to apply external force to insert them into the ground and pull them out after the construction is completed.

[0004] In winter, when the frozen soil layer and the construction soil are relatively hard, it is often difficult to drive the grounding rod of the grounding wire into the ground, and the grounding rod is easily damaged by the hammer. In this case, it is very difficult to insert and pull out the grounding rod.

[0005] Therefore, a threaded rod is mostly used, and the rod is drilled into the soil through tools such as electric drills and wrenches, so as to protect the rod and improve the efficiency of the rod entering the soil.

[0006] Moreover, when the soil is relatively hard, the rod is prone to tilt during the process of piercing into the soil. The force angle of the tilted rod changes, resulting in the rod being more difficult to enter the soil.

[0007] For this reason, a grounding rod for winter maintenance operations is proposed to facilitate the grounding of the rod on the frozen soil layer or relatively hard soil. Content of the Utility Model

[0008] The purpose of the utility model is to provide a grounding rod for winter maintenance operations to solve the problems raised in the above background technique.

[0009] In order to solve the above technical problems, the utility model provides the following technical solution: A grounding rod for winter maintenance operations, including a rod mechanism and an auxiliary mechanism;

[0010] The auxiliary mechanism includes a support plate, the bottom of the support plate is fixedly connected with an earth-penetrating knife barrel, a through hole is opened in the center of the support plate and the earth-penetrating knife barrel, and the diameter of the through hole is larger than the diameter of the rod body of the rod mechanism. The rod mechanism pierces through the through hole;

[0011] The bottom of the support plate is fixedly connected with positioning thorns, and the positioning thorns are annularly arranged outside the earth-penetrating knife barrel;

[0012] The top of the support plate is fixedly connected with a fulcrum convex ring.

[0013] Preferably, the drill rod mechanism includes a threaded drill rod, the top of the threaded drill rod is fixedly connected with a polygonal rod, and a grounding strip is fixedly connected to the outer surface of the threaded drill rod;

[0014] A soil discharge groove is formed in the outer surface of the threaded drill rod, one end of the soil discharge groove penetrates through the bottom of the threaded drill rod, and the other end of the soil discharge groove extends below the grounding strip.

[0015] Preferably, a clamping groove is arranged between the grounding strips, the grounding strips are elastic, and the clamping groove clamps the copper nose of the grounding wire and is fixed by bolts and nuts.

[0016] Preferably, the soil entry knife barrel is downwardly tapered, and the diameter of the through hole formed in the soil entry knife barrel is the same up and down.

[0017] Preferably, the bottom edge of the support plate is provided with a notch, the depth of the notch does not exceed half of the thickness of the support plate, and the number of the notches is multiple.

[0018] Preferably, the positioning thorn is threadedly connected to the support plate;

[0019] An internal thread is arranged inside the soil entry knife barrel;

[0020] A detachable cleaning mechanism is connected inside the internal thread.

[0021] Preferably, the cleaning mechanism includes a substrate, a threaded column is fixedly connected to the bottom of the substrate, and a brush is fixedly connected to the top of the substrate;

[0022] The threaded column is threadedly connected to the internal thread.

[0023] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0024] First, by setting the support plate and arranging the soil entry knife barrel and the positioning thorn at the bottom of the support plate, before the threaded drill rod is inserted into the soil, the soil entry knife barrel is inserted into the soil by means of tools such as a hammer, and then the threaded drill rod is drilled into the soil from the through hole in the middle of the support plate. Since the inclination angle of the threaded drill rod is blocked by the support plate, the threaded drill rod will not tilt or slide, achieving the effect that the drill rod can be easily drilled into the soil on hard soil or frozen soil.

[0025] Second, the utility model opens a soil discharge groove on the outer surface of the threaded drill rod. During the process of the threaded drill rod drilling into the soil, the soil will rise from the position of the soil discharge groove after being extruded, so as to discharge the soil, avoid the soil from becoming more compact after being pressed, reduce the resistance of the soil when the threaded drill rod drills in and pulls out, and further improve the efficiency of the drill bit entering the soil.

[0026] Third, the utility model sets a base plate, fixedly connects a threaded column at the bottom of the base plate and is in threaded connection with an internal thread. At the same time, a brush is fixedly connected to the top of the base plate. After the threaded drill rod is taken out, the soil in the thread groove of the threaded drill rod can be cleaned by the brush, so that the threaded drill rod is kept clean, and the service life of the threaded drill rod is improved.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-8 , a grounding drill rod for winter maintenance work, which includes a drill rod mechanism 1 and an auxiliary mechanism 2;

[0038] The auxiliary mechanism 2 includes a support plate 201. The bottom of the support plate 201 is fixedly connected with an earth penetration cutter barrel 202, which is used to penetrate into the soil and limit the outer surface of the threaded drill rod 101 through the inner wall of the earth penetration cutter barrel 202, so that when the threaded drill rod 101 drills the soil, the inclination angle is not limited to be too large. A through hole is opened in the center of the support plate 201 and the earth penetration cutter barrel 202, and the diameter of the through hole is larger than the diameter of the rod body of the drill rod mechanism 1. The drill rod mechanism 1 penetrates from the through hole;

[0039] The bottom of the support plate 201 is fixedly connected with positioning thorn needles 203. The positioning thorn needles 203 are annularly arranged outside the earth penetration cutter barrel 202 to improve the support strength of the support plate 201 and prevent the support plate 201 from rotating following the drill rod mechanism 1 when the drill rod mechanism 1 rotates;

[0040] The top of the support plate 201 is fixedly connected with a fulcrum convex ring 204. When the electric tool or manual tool rotates in reverse and the threaded drill rod 101 is sucked by the soil and cannot rise, a tool is needed to lift the threaded drill rod 101 at this time. The function of setting the fulcrum convex ring 204 is to serve as the support point of the lever, which is convenient for using a tool to lift the threaded drill rod 101. Without the fulcrum convex ring 204, there is no stable inclination angle between the end of the tool and the threaded drill rod 101, resulting in the tool being difficult to exert force.

[0041] Through the above technical solutions, the support plate 201 is provided, and the earth penetration cutter barrel 202 and the positioning thorn needles 203 are arranged at the bottom of the support plate 201. Before the threaded drill rod 101 is inserted into the soil, the earth penetration cutter barrel 202 is inserted into the soil by a tool such as a hammer, so that the bottom of the support plate 201 is in contact with the soil surface, and then the threaded drill rod 101 is drilled into the soil from the through hole in the middle of the support plate 201;

[0042] During the initial drilling process of the threaded drill rod 101 into the soil, due to the height difference between the top of the support plate 201 and the ground, and the through-hole limiting the end of the threaded drill rod 101, since the inclination angle of the threaded drill rod 101 is blocked by the support plate 201, the threaded drill rod 101 will not tilt or slide, achieving the effect that the drill bit can easily penetrate into the soil on hard soil or frozen soil;

[0043] Normally, when the threaded drill rod 101 tilts, its vertically downward acting force will be divided into two directions due to the tilt of the threaded drill rod 101, one direction is inclined and the other direction is vertical, resulting in the need for more force for the threaded drill rod 101 to penetrate into the soil. Therefore, it will be more difficult to penetrate into hard soil.

[0044] Specifically, the drill bit mechanism 1 includes a threaded drill rod 101, a polygonal rod 102 is fixedly connected to the top of the threaded drill rod 101, and a grounding strip 103 is fixedly connected to the outer surface of the threaded drill rod 101;

[0045] A soil discharge groove 104 is formed on the outer surface of the threaded drill rod 101. One end of the soil discharge groove 104 penetrates through the bottom of the threaded drill rod 101, and the other end of the soil discharge groove 104 extends below the grounding strip 103.

[0046] Through the above technical solution, the polygonal rod 102 provided is used to connect with electric tools and manual tools, and the threaded drill rod 101 is rotated by an electric tool or a wrench to penetrate into the soil;

[0047] The grounding strip 103 provided is used to connect with a grounding wire, so as to conduct the induced electricity into the ground through the grounding strip 103.

[0048] Specifically, a clamping groove 1031 is provided between the grounding strips 103. The grounding strip 103 has elasticity. The clamping groove 1031 clamps the copper nose of the grounding wire and is fixed by bolts and nuts.

[0049] Through the above technical solution, the clamping groove 1031 provided is used to clamp the copper nose, and at the same time, it is fixed by the cooperation of bolts and nuts, which has a larger contact area and a more firm fixing performance compared with direct fixing.

[0050] Specifically, the soil entry knife barrel 202 is a downward cone, and the diameter of the through-hole formed on the soil entry knife barrel 202 is the same up and down.

[0051] Through the above technical solution, the soil entry knife barrel 202 is set as a cone, so that the soil entry knife barrel 202 can penetrate into the soil more conveniently;

[0052] Set the diameter of the through hole in the soil-entering cutter barrel 202, thus achieving the effect that the wall surface of the soil-entering cutter barrel 202 is thick at the top and thin at the bottom, making the bottom of the soil-entering cutter barrel 202 form a cutting edge effect, and the resistance received during the insertion into the soil will be smaller.

[0053] Specifically, a notch 205 is provided at the bottom edge of the support plate 201. The depth of the notch 205 does not exceed half of the thickness of the support plate 201, and the number of notches 205 is multiple.

[0054] Through the above technical solution, the provided notch 205 is used to facilitate the removal of the support plate 201 after removing the threaded drill rod 101. When removing the support plate 201, place the threaded drill rod 101 outside the support plate 201 as the support point of the lever, and then insert a tool into the inside of the notch 205, and the support plate 201 can be easily removed;

[0055] Set the depth of the notch 205 to avoid the thickness of the edge of the support plate 201 being too thin after the notch 205 is too deep. When lifting the support plate 201 through the notch 205, the thinner edge is prone to breakage.

[0056] Specifically, the positioning thorn 203 is threadedly connected to the support plate 201;

[0057] Internal threads 206 are provided inside the soil-entering cutter barrel 202;

[0058] A detachable cleaning mechanism 3 is connected inside the internal threads 206.

[0059] Through the above technical solution, the positioning thorn 203 and the support plate 201 are fixed by threaded connection, so that when not in use, the positioning thorn 203 can be disassembled to facilitate taking and storage;

[0060] And after installing the cleaning mechanism 3, if the positioning thorn 203 cannot be disassembled, it will be inconvenient to take the support plate 201, and there is a risk of being stabbed by the positioning thorn 203;

[0061] When the positioning thorn 203 is detachable, the cleaning mechanism 3 can be used to clean the soil on the surface of the threaded drill rod 101 by holding the outer surface of the support plate 201 or the soil-entering cutter barrel 202.

[0062] Specifically, the cleaning mechanism 3 includes a substrate 301. A threaded column 302 is fixedly connected to the bottom of the substrate 301, and a brush 303 is fixedly connected to the top of the substrate 301;

[0063] The threaded column 302 is threadedly connected to the internal threads 206.

[0064] Through the above technical solution, the provided substrate 301 is used to connect the threaded post 302 and the bristles 303, and limit the installation depth of the threaded post 302. When the threaded post 302 completely enters the through hole, the bottom of the substrate 301 overlaps with the top of the support plate 201, facilitating the rotation of the threaded post 302 through the substrate 301 for disassembly and assembly;

[0065] If the substrate 301 is not provided and the bristles 303 are directly connected to the threaded post 302, then when the threaded post 302 penetrates into the through hole, the threaded post 302 can only be rotated for disassembly by holding the bristles 303. Such a disassembly method is extremely inconvenient to operate and has a great impact on the service life of the bristles 303.

[0066] During use, by providing the support plate 201 and arranging the soil penetration cutter barrel 202 and the positioning thorn needles 203 at the bottom of the support plate 201, before the threaded drill rod 101 penetrates into the soil, the soil penetration cutter barrel 202 is inserted into the soil by means of tools such as a hammer, and then the threaded drill rod 101 is drilled into the soil from the through hole in the middle of the support plate 201. Since the inclination angle of the threaded drill rod 101 is blocked by the support plate 201, the threaded drill rod 101 will not tilt or slide, achieving the effect of facilitating the penetration of the drill into the soil on hard soil or frozen soil;

[0067] By providing soil discharge grooves 104 on the outer surface of the threaded drill rod 101, during the process of the threaded drill rod 101 penetrating into the soil, the soil will rise from the position of the soil discharge grooves 104 after being squeezed, thereby discharging the soil, preventing the soil from becoming more compact under pressure, reducing the resistance of the soil when the threaded drill rod 101 penetrates and withdraws, and further improving the efficiency of the drill penetrating into the soil.

[0068] And when removing the threaded drill rod 101, tools such as a crowbar are inserted into the thread gap of the threaded drill rod 101 and the support plate 201 is used as a backing plate, and the crowbar is pried with the notch 205 as the support point to prevent the soil structure from becoming soft and difficult to apply force to remove the threaded drill rod 101 after being damaged;

[0069] By providing the substrate 301, fixedly connecting the threaded post 302 to the internal thread 206 at the bottom of the substrate 301 for threaded connection, and fixedly connecting the bristles 303 to the top of the substrate 301, after removing the threaded drill rod 101, the soil in the thread groove of the threaded drill rod 101 can be cleaned by the bristles 303, keeping the threaded drill rod 101 clean and improving the service life of the threaded drill rod 101.

[0070] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
