Description

Technical Field

[0001] This utility model relates to the field of grounding electrode corrosion protection technology, specifically a galvanized round steel grounding electrode corrosion protection hydraulic connector. Background Technology

[0002] In fields such as power, communications, and building lightning protection, grounding systems are an important component for ensuring equipment safety and personal safety.

[0003] In grounding systems, the grounding electrode is a crucial component. Currently, the primary grounding electrode is galvanized round steel. Traditionally, different galvanized round steel grounding electrodes are connected by welding or bolting. However, both methods have drawbacks. Welding has several shortcomings: high temperatures can cause localized melting of the galvanized layer, compromising its corrosion resistance; welding quality is difficult to guarantee, leading to issues like incomplete welds and weak welds; and the large amount of high-temperature spatter generated during welding can easily ignite nearby combustibles, causing fires, especially in forest and pastoral areas where government agencies strictly prohibit all open flame work during fire season. This poses a significant challenge to the construction, maintenance, and troubleshooting of power transmission and distribution grounding networks located in the field. Bolted connections have the following drawbacks: poor reliability; long-term burial in soil can lead to corrosion, particularly at the top of the bolt threads. Even slight corrosion can reduce the load-bearing capacity, causing the bolts to loosen or even break, thus affecting the grounding effect.

[0004] To address the shortcomings of the two aforementioned connection methods, inventors have designed hydraulic connectors. While hydraulic connectors improve connection strength to some extent, their corrosion resistance still needs improvement, especially in harsh environments such as humid conditions. Hydraulic deformation can cause the zinc layer of the connector to detach. Once moisture and salt from the soil penetrate, corrosion occurs at the detached areas, ultimately leading to the failure of the grounding system. Utility Model Content

[0005] To address the problem of grounding system failure caused by corrosion of existing hydraulic connectors, this invention provides a corrosion-resistant hydraulic connector for galvanized round steel grounding electrodes, which ensures connection strength while preventing grounding system failure due to corrosion.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a galvanized round steel grounding body anti-corrosion hydraulic connector, including a connecting pipe that can be fitted onto the galvanized round steel grounding body and pressed and fixed. The end face of the connecting pipe is provided with a flared opening along its circumference. The inner side wall of the flared opening and the galvanized round steel grounding body form a sealing area. The sealing area is filled with a sealing element. The connecting pipe is detachably connected to a fixing element for pressing the sealing element into the sealing area.

[0007] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding electrode, the diameter of the flared opening gradually decreases from the outside to the inside.

[0008] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding body of the utility model: the sealing element is set as a conical rubber sleeve, the large end of the rubber sleeve is located outside the sealing area, and the small end of the rubber sleeve extends into the interior of the sealing area.

[0009] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding body of the utility model: the connecting pipe is provided with an external thread, the fixing member includes an annular body, one end of the inner wall of the annular body near the connecting pipe is provided with an internal thread that matches the external thread, the other end of the inner wall of the annular body is provided with a blocking part, and when the annular body is screwed to the connecting pipe, the blocking part fits against the large end of the rubber sleeve.

[0010] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding body of the utility model: the annular body is provided with a knife-relief groove, which is located between the blocking part and the internal thread. The inner cavity of the knife-relief groove forms a receiving space, and a part of the seal can enter the receiving space after deformation.

[0011] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding body, the inner diameter of the connecting pipe is larger than the diameter of the galvanized round steel grounding body.

[0012] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding electrode of the utility model: the length of the flared opening is less than the length of the sealing element.

[0013] As a further optimization of the anti-corrosion hydraulic connector for galvanized round steel grounding body of the utility model: the surface of the connecting pipe is distributed with multiple recesses, and the recesses are located in the middle of the connecting pipe.

[0024] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the material and structure of the galvanized round steel grounding body 4, the model of the hydraulic equipment, etc.

[0025] Example 1

[0026] A galvanized round steel grounding electrode corrosion-resistant hydraulic connector, such as Figures 1 to 6As shown, the system includes a connecting pipe 1 that can be fitted onto and pressed firmly onto galvanized round steel grounding bodies 4. Two adjacent galvanized round steel grounding bodies 4 are connected by the connecting pipe 1, with the connecting pipe 1 pressed firmly onto these two connecting pipes 1. The connecting pipe 1 is made of high-performance stainless steel, possessing excellent mechanical properties and corrosion resistance. To facilitate the fitting of the connecting pipe 1 onto two adjacent galvanized round steel grounding bodies 4, the inner diameter of the connecting pipe 1 is larger than the diameter of the galvanized round steel grounding body 4, forming a channel 2 within the connecting pipe 1 for the galvanized round steel grounding body 4 to pass through. The pressing method can employ hydraulic equipment to press the connecting pipe 1 firmly onto the galvanized round steel grounding body 4, ensuring a tight fit between the inner wall of the connecting pipe 1 and the galvanized round steel, guaranteeing connection stability. The surface of the connecting pipe 1 has multiple recesses 9, formed when the hydraulic equipment presses the connecting pipe 1. To avoid affecting the installation and fixing of other components, the recesses 9 are located in the middle of the connecting pipe 1. When hydraulic equipment is used to tighten the connecting pipe 1 and the galvanized round steel grounding body 4, the zinc layer of the galvanized round steel grounding body 4 may peel off due to hydraulic deformation, making it susceptible to corrosion. The end face of the connecting pipe 1 has a flared end 3 along its circumference. The inner wall of the flared end 3 forms a sealing zone with the galvanized round steel grounding body 4. A sealing element 5 is filled within this sealing zone, effectively preventing external corrosive substances from intruding and corroding the areas where the zinc layer has peeled off, thus enhancing the sealing performance of the connection. The connecting pipe 1 is detachably connected to a fixing element 6 for pressing the sealing element 5 within the sealing zone, further enhancing the sealing effect and preventing the sealing element 5 from falling off. Both the fixing element 6 and the connecting pipe 1 are coated with conductive anti-corrosion paint, effectively preventing corrosion of the fixing element 6 and the connecting pipe 1, extending the service life of the connecting elements, and consequently extending the service life of the galvanized round steel grounding body 4.

[0027] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0028] Example 2

[0029] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: to further enhance the sealing effect, the diameter of the flare 3 gradually decreases from the outside to the inside, i.e., the flare 3 is conical from the outside to the inside. The sealing element 5 is a conical rubber sleeve, the shape of which is adapted to the flare 3 to ensure that the rubber sleeve can fill the sealing area. The large end 12 of the rubber sleeve is located outside the sealing area, and the small end 11 extends into the sealing area. Because the rubber sleeve has a certain degree of elasticity, and the length of the flare 3 is less than the length of the sealing element 5, squeezing the rubber sleeve can push it into the sealing area, further ensuring the sealing effect and preventing the rubber sleeve from falling off directly.

[0030] Example 3

[0031] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in:

[0032] In order to fix the fastener 6 to the connecting pipe 1 and press the rubber sleeve into the sealing area, the connecting pipe 1 is provided with an external thread 14. The fastener 6 includes an annular body. The inner wall of the annular body is provided with an internal thread 13 that mates with the external thread 14 at one end near the connecting pipe 1. The other end of the inner wall of the annular body is provided with a blocking part 8. When the annular body is screwed to the connecting pipe 1, the blocking part 8 fits against the large end 12 of the rubber sleeve.

[0033] The specific installation method is as follows: First, put the connecting pipe 1 on two adjacent galvanized round steel grounding bodies 4, and then press the connecting pipe 1 tightly on the surface of the galvanized round steel grounding body 4; next, put the rubber sleeve on the end of the galvanized round steel grounding body 4 located outside the connecting pipe 1, and move the rubber sleeve into the sealing area along the direction from the outside to the inside; at this time, put the annular body on the end of the galvanized round steel grounding body 4 located outside the connecting pipe 1, and push the annular body along the direction from the outside to the inside. During the pushing process, the large end 12 of the rubber sleeve first enters the inner hole 10 of the annular body; continue to push the annular body, at this time the external thread 14 and the internal thread 13 are engaged and screwed together until the large end 12 of the rubber sleeve is in contact with the blocking part 8.

[0034] In addition to threaded connection, a screw-on connection can also be used. The inner wall of the annular body is provided with two partition strips distributed along its circumference, and there is a gap between the two partition strips. The end of the connecting pipe 1 near its end is provided with two protrusions that cooperate with the partition strips along the circumference. The protrusions can pass through the gap, and during the rotation of the annular body, the protrusions can be matched with the partition strips to lock the annular body onto the connecting pipe 1.

[0035] To ensure a good seal, the inner diameter of the annular body is smaller than the large end 12 of the rubber sleeve. Therefore, the large end 12 of the rubber sleeve will deform to a certain extent when it enters the annular body. A relief groove 7 is provided on the annular body, located between the blocking part 8 and the internal thread 13. The inner cavity of the relief groove 7 forms a receiving space, allowing a portion of the seal 5 to enter this space after deformation. The relief groove 7 provides sufficient space to accommodate the deformation of the rubber sleeve.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
