Abstract
Description
/ 7 Grounding rod with water jet penetration. Innovation field
[001] The present innovation belongs to the field of electrical devices, more specifically to a hollow rod for grounding systems, capable of allowing the passage of a jet of water to promote its insertion into the ground. History of innovation
[002] Traditional grounding systems use rods driven into the ground, comprising one or more grounding rods joined in series, including: a) the rod, which acts as an electrode; in a grounding system, the rod is the single piece inserted into the ground, while the electrode encompasses a rod or a set of rods physically interconnected in series; b) grounding, which consists of one or more electrodes driven into the ground and electrically interconnected.
[003] It is worth noting that it is common to interconnect several electrodes to achieve the effectiveness that meets the requirements for grounding.
[004] Connecting electrical equipment to the grounding system allows that, in the event of a fault in the equipment insulation or an atmospheric discharge, the current passes through the grounding conductor instead of passing through the body of a person who may be in contact with the equipment.
[005] Thus, as is known among professionals in the field of electricity, with a view to protecting machines, equipment and lives, grounding of electrical and electronic machines and equipment in homes, commercial and industrial establishments, as well as installations such as towers, metal fences and others, is recommended, if not mandatory. Petition 870260054595, dated 05 / 06 / 2026, page 7 / 17 / 7
[006] Good grounding depends on several factors, from the type of soil, considering its resistivity, the quality and correct specification of the material, the care in handling and transport, as well as the use of tools and special care when inserting the electrodes and choosing the location.
[007] Grounding, therefore, has the function of dissipating electrical current surges caused by atmospheric discharges or electrical surges in electrical installations, in addition to attenuating electrical noise.
[008] By achieving better grounding performance, there will be fewer electrode insertion points and, consequently, fewer interventions in urban installations, such as broken sidewalks and uprooted trees, in addition to a smaller number of locations subject to contamination by the electrodes. One of the main factors in achieving better efficiency is the electrode depth, a characteristic that is optimized in this new version of the grounding rod.
[009] To understand the problems of the conventional grounding system, it is necessary to know the conventional rod, normally made of a straight, solid iron bar, coated with a layer of copper or some other non-oxidizing conductive material.
[010] This conventional rod is a difficult piece to install, traditionally installed manually, with the introduction into the ground done with axial blows promoted by a heavy tool, such as a hammer, forcing the rod to penetrate the ground.
[011] In the traditional system, the rods can be damaged during placement and immediately discarded, directly causing financial and ecological damage.
[012] In many cases, the conventional rod is partially damaged during installation because the thin coating layer (which is a protection against oxidation) is partially broken (sanded) by rubbing directly with sand, Petition 870260054595, dated 05 / 06 / 2026, page 8 / 17 / 7 gravel and other abrasive materials present in the soil. Oxidation causes a decrease in lifespan, compromising efficiency, shortening the time of effectiveness and consequently causing losses in relation to safety, in addition to financial and ecological losses due to premature disposal.
[013] When the coating material layer is completely or partially broken, the iron electrode oxidizes and the dissipation of an atmospheric discharge is compromised by the insulation of the conductive material and the ground.
[014] An eventual inspection may reveal this defect and promote its repair, generating not only financial loss, but also a safety risk and waste due to the disposal of part of the material. It is worth noting that connections (sleeves) thicker than the nominal diameter of the rod are used in the joints, further hindering penetration into the soil.
[015] From an ergonomics point of view, in the conventional system, using the tool to strike the rod, professionals are subject to various accidents, in addition to trauma caused by the tools suitable for performing the service, mainly in the spine.
[016] The state-of-the-art solutions do not address the same characteristics as the present innovation. For example, document MU8902648-9 presents an electrical grounding rod characterized by a main body consisting of a rod, which describes a cross-shaped transverse shape with 90° angles or an X shape, with tabs, whose lower sections taper to form a tip, with one of the tabs having holes in the upper section, while another transversely projects a support with holes for fixing cables, in derivative arrangements the rods have a V or T-shaped transverse shape. Petition 870260054595, dated 05 / 06 / 2026, page 9 / 17 / 7
[017] Document MU6900120-0 describes a grounding rod defined by a round bar or provided with a conical end, which may be of the standard type or the extendable type, in the latter case having threaded ends that allow the joining of several rods through splicing sleeves and also a marking screw to protect the threads of the sleeve and the extendable rod, with connection elements provided to connect the ground cable to the grounding rod.
[018] Thus, the present innovation brings a practical approach to solving these various problems, contributing to the practical and efficient installation of electrodes with self-penetrating rods by water jet, dispensing with the use of crude and non-ergonomic tools. Description of the figures
[019] Figure 1 represents a longitudinal cross-sectional view of the grounding rod components of the present invention, where its body (1) and its conical tip (2) are visible, with the respective threads (3) of the conical tip (2), external thread (4) of the body (1) and internal thread (5) of the body (1).
[020] Figure 2 illustrates a detailed view of the association of the conical tip (2) to the body (1) of the rod.
[021] Figure 3 represents a longitudinal cross-sectional view of the grounding rod components of the present invention, where its body (1) and its conical tip (2) are visible, insulated (1A), in simple association (1B) and in series association (1C).
[022] Figure 4 shows a schematic representation of the use of the rod of the present innovation in the soil driving process (6), illustrating the connection with a pump (7) that propels the fluid (8) through the body (1) and the conical tip (2). Petition 870260054595, dated 05 / 06 / 2026, page 10 / 17 / 7 Description of the innovation
[023] The innovation proposed here consists of a device for installing electrical grounding systems, consisting of a hollow, cylindrical rod (1) with an external thread (4) and an internal thread (5) at its ends. An accessory is used that forms a conical tip (2), also hollow, but with a reduced internal diameter, equipped with a thread (3), which can be internal or external, to be connected to the threaded end of the body (1), in order to increase the pressure of the fluid (8) and form the jet responsible for erosion at the conical tip (2) of the rod.
[024] The hollow body (1) provides passage for a fluid (8), preferably water, optionally compressed air, or a combination of two or more fluids, which, under pressure, flows out through the conical tip (2), opening a path in the soil (6) for the rod to penetrate by means of controlled erosion.
[025] In a preferred embodiment of the present invention, a pump (7) pressurizes the fluid (8) and connects to the rod by means of a tube, preferably flexible, such as a hose, engaging the internal thread (5) at its upper end by means of an appropriate connection device.
[026] Optionally, the fluid (8) can be pressurized by other methods, such as, for example, a height difference, generating a pressure by level difference.
[027] With the passage of fluid (8) through the conical tip (2), the flow causes controlled erosion, which can be better controlled with different shapes of the conical tip (2), depending on the type of soil (6) where the installation is carried out, expelling and removing material, such as earth, clay, sand, pebbles, etc. from the conical tip (2), making a vertical channel in the soil and thus facilitating penetration into the soil (6). Petition 870260054595, dated 05 / 06 / 2026, page 11 / 17 / 7
[028] It is worth noting that the fluid (8) normally returns to the surface on the outside of the rod, naturally carrying the removed material out of the channel. This is the main difference and advantage of the water jet penetrating rod compared to existing models.
[029] Additionally, the presented rod can be lengthened by engaging multiple body parts (1), promoting the interaction of the external thread (4) of one body part (1) with the internal thread (5) of another body part (1), forming a single artifact, as illustrated in Figure 3.
[030] The grounding rod presented here aims to modernize and modify the practice of installing driven rod grounding systems, significantly facilitating operation, improving efficiency, increasing system durability, and being less harmful to the environment.
[031] Because it is capable of reaching a greater depth, the rod of the present innovation increases the efficiency of grounding, promoting a smaller environmental impact due to the reduced need for intervention in the environment, for example, requiring a smaller area and, consequently, a smaller number of trees removed.
[032] Additionally, since there is no disposal of damaged rods, as opposed to the conventional system, the operational cost is also significantly reduced.
[033] It is worth highlighting that the rod diameter can be adapted to the grounding conditions to be performed, using rods with smaller or larger diameters as needed for the grounding. It is noteworthy that this hollow rod can be used in much larger diameters and installed in grounding systems with a high degree of demand, something that would not be feasible using conventional rods. Petition 870260054595, dated 05 / 06 / 2026, page 12 / 17 / 7
[034] Another great advantage of the rod described here, which operates with water jet penetration, is that, in systems that require high reliability and durability, this system allows the installation of more effective rods, constructed from a single non-oxidizing material, especially copper.
[035] Another advantage offered by this system is when there is a need to treat the soil (6) with gel, to lower its resistivity, the gel itself can be used together with the erosion fluid (8), achieving a homogeneous application at the ends, with a higher concentration at the bottom of the electrode, which is the part of greatest interest for dissipating the electrical surge.

Many modifications and other representations of the invention will come to mind for those skilled in the art to which this innovation pertains, having the benefit of the teaching set forth in the preceding descriptions and accompanying drawings. Furthermore, it is to be understood that the invention is not limited to the specific form disclosed, and that modifications and other forms are understood to be included within the scope of the appended claims. Although specific terms are employed herein, they are used only in a generic and descriptive manner and not for the purpose of limitation. Petition 870260054595, dated 05 / 06 / 2026, page 13 / 17
