Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage cable joints, in particular to a corrosion-resistant high-voltage cable joint. BACKGROUND

[0002] In modern society, high-voltage power transmission is crucial for ensuring industrial production, urban operation, and residential electricity. With the continuous growth of electricity demand and the continuous advancement of power grid construction, high-voltage cables, as the key carriers of power transmission, their connection performance directly affects the safe and stable operation of the entire power system. Therefore, developing high-performance corrosion-resistant high-voltage cable joints has become an important issue in the power field.

[0003] Traditional high-voltage cable joints have many shortcomings in electrical connection. Early connection methods mostly use simple winding or crimping, which is difficult to ensure stable and low-resistance electrical connection between cables. In the process of high-voltage current transmission, poor contact problems frequently occur, leading to increased resistance. According to Joule's law Q = I 2 Rt(where Q is heat, I is current, R is resistance, and t is time), increased resistance will generate excessive heat at the joint, not only causing power loss, but also possibly causing heating and even electrical accidents such as short circuits, fires, etc., seriously threatening the safe operation of the power system.

[0004] In addition, traditional cable joints have weak protection against water vapor. In actual application environments, high-voltage cables often need to be laid underground, underwater, or in humid environments, where water vapor can easily enter the joint. Once water vapor enters, it will accelerate the corrosion of the conductor, reduce the conductivity of the conductor, and reduce the performance of the insulating material, significantly increasing the risk of insulation breakdown. For example, in some coastal areas or rainy areas, due to high air humidity, the probability of failure of traditional cable joints due to water vapor intrusion is significantly increased, causing great distress to local power supply.

[0005] Moreover, traditional cable joints have poor stability and reliability of electrical connection when facing complex and variable operating environments. For example, in industrial areas, cables may be eroded by chemicals; in earthquake-prone areas, cables may be affected by vibrations. Traditional joints are difficult to maintain good electrical connection performance in these complex environments for a long time, leading to interruptions in power transmission, affecting enterprise production and residential life, and causing many adverse effects on the economy and society. SUMMARY

[0006] Technical problems solved: High-voltage cables often need to be laid underground, under water or in humid environments, and water vapor is extremely easy to enter the interior of the joint. Once water vapor enters, it will accelerate the corrosion of the conductor, reduce the conductivity of the conductor, and reduce the performance of the insulation material, greatly increasing the risk of insulation breakdown. For example, in some coastal areas or rainy areas, due to high air humidity, the probability of failure of traditional cable joints due to water vapor intrusion is significantly increased, causing great inconvenience to local power supply.

[0007] In view of the deficiencies of the prior art, the present application provides a corrosion-resistant high-voltage cable joint, thereby solving the technical problems mentioned in the background art.

[0008] To achieve the above purpose, the present application is realized by the following technical scheme:

[0009] The specific structure of a corrosion-resistant high-voltage cable joint comprises a first hollow mounting cylinder, a mounting mechanism is fixedly installed on the side wall of the first hollow mounting cylinder, the mounting mechanism comprises a first anchoring flange, the first anchoring flange is fixedly installed on the side wall of the first hollow mounting cylinder, a second anchoring flange is sleeved on the side wall of the first anchoring flange, a second hollow mounting cylinder is fixedly installed on the side wall of the second anchoring flange, a first full-thread cylinder is inserted into the first hollow mounting cylinder and the second hollow mounting cylinder, a second concave connecting plate is fixedly installed on the side wall of the left first full-thread cylinder, a first convex connecting plate is fixedly installed on the side wall of the right first full-thread cylinder, an outer threaded mounting column is threadedly installed in the first full-thread cylinder, and an inner threaded mounting cylinder is threadedly installed on the side wall of the first full-thread cylinder.

[0010] In a possible implementation, the second concave connecting plate is inserted into the second hollow mounting cylinder.

[0011] In a possible implementation, the first convex connecting plate is inserted into the first hollow mounting cylinder.

[0012] In a possible implementation, the first convex connecting plate is inserted into the second concave connecting plate.

[0013] In a possible implementation, the side walls of the first hollow mounting cylinder and the second hollow mounting cylinder are both threadedly installed with an inner threaded connecting cylinder.

[0014] In a possible implementation, the side walls of the two inner threaded connecting cylinders are both fixedly installed with a conical extrusion cylinder.

[0015] In a possible implementation, the ends of the first hollow mounting cylinder and the second hollow mounting cylinder away from the first anchoring flange and the second anchoring flange are both fixedly installed with a conical connecting cylinder.

[0016] In a possible implementation, the two conical connecting barrels are fixedly installed with conical limiting plates at one end away from the first and second hollow mounting barrels.

[0017] In a possible implementation, the two conical connecting barrels are fixedly installed with conical limiting plates at one end away from the first and second hollow mounting barrels.

[0018] In a possible implementation, the inner threaded mounting barrel is made of PVC material.

[0019] Compared with the prior art, the beneficial effects are as follows:

[0020] 1. In this scheme, the high-voltage cable joint performs outstandingly in electrical connection, from initially connecting the cable end with the outer threaded mounting column, to rotating the outer threaded mounting column into the first full-threaded barrel by thread cooperation. This close thread connection not only realizes mechanical fastening, but more importantly, builds a stable transmission bridge for electric current, ensuring smooth electrical connection path between cables. Stable electrical connection is the cornerstone of safety and efficiency when high-voltage cables are running. Any poor contact may cause increased resistance, heating, and even electrical accidents. In addition, after the first full-threaded barrel is rotated into the inner threaded mounting barrel, the inner threaded mounting barrel contacts the first convex connecting plate to form a sealed space, effectively preventing water vapor from entering and avoiding conductor corrosion and insulation performance degradation. This design ensures stable and reliable operation of the electrical connection part in long-term complex environments and provides solid protection for high-voltage power transmission.

[0021] 2. In this scheme, the cable joint is designed ingeniously and practically for cable fixation. By rotating the inner threaded connecting barrel to drive the conical extrusion barrel to slide on the side wall of the conical limiting plate, the cable is extruded to achieve firm fixation. After the right side operation is completed, the left side is operated symmetrically, so that both cables can be stably fixed at both ends of the joint, preventing displacement or loosening of the cables during operation, which affects electrical connection. At the same time, the excess cable is stored inside the conical connecting barrel, making the overall structure more compact and reasonable. This design not only ensures the stability of cable fixation and adapts to external forces such as tension and vibration that high-voltage cables may face in different working conditions, but also optimizes space utilization, enabling the cable joint to achieve efficient layout in limited space, suitable for various occasions with limited installation space.

[0022] 3. In this scheme, the cable joint has excellent sealing performance, greatly improving the durability. On the one hand, the closed space formed by the internal thread mounting cylinder and the first convex connecting plate can effectively block the water vapor from entering, protecting the internal electrical connecting components. On the other hand, the expansion rubber sheet in the tapered connecting cylinder will expand under the influence of external factors such as temperature and humidity, filling the gap between the cable and enhancing the sealing effect, preventing the intrusion of corrosive gases from the outside. The components are tightly connected and matched to form a relatively sealed structure, effectively resisting harsh environments and ensuring that the internal electrical performance is not disturbed during long-term operation. This makes the cable joint able to work stably in harsh environments such as humidity and chemical corrosion, prolonging the service life and reducing maintenance costs and replacement frequency.

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present application will be described in detail with reference to the accompanying drawings, however the present application can be implemented in various different forms, therefore the present application is not limited to the embodiments described below, in addition, in order to more clearly describe the present application, components not connected with the invention will be omitted from the drawings;

[0032] The technical solutions in the embodiments of the present application are to solve the problems in the background art, and the general idea is as follows:

[0033] Embodiments:

[0034] Please refer to Figures 1 to 6As shown, the embodiment introduces a specific structure of a corrosion-resistant high-voltage cable joint, which comprises a first hollow mounting cylinder 11. When in use, two cables are respectively threaded through the two tapered limiting plates 19 until the inside of the first hollow mounting cylinder 11 and the second hollow mounting cylinder 23. The first hollow mounting cylinder 11 is fixedly installed with a first anchoring flange 12, and the end of the cable is connected with the external thread mounting column 15, at this time, the external thread mounting column 15 is aligned with the first full thread cylinder 13, and then the external thread mounting column 15 is rotated counterclockwise, since the first full thread cylinder 13 has a thread structure matched with the external thread mounting column 15, the external thread mounting column 15 can be gradually screwed into the first full thread cylinder 13, such connection not only provides mechanical fastening, but more importantly, ensures the continuity of the electrical connection path between the cables, and ensures the smooth transmission of current between the two cables. The first anchoring flange 12 is sleeved with a second anchoring flange 22, after the external thread mounting column 15 is screwed into the first full thread cylinder 13, the first full thread cylinder 13 is aligned with the internal thread mounting cylinder 16, and the internal thread mounting cylinder 16 is rotated counterclockwise, the thread in the internal thread mounting cylinder 16 interacts with the thread on the side wall of the first full thread cylinder 13, so that the first full thread cylinder 13 can be screwed into the internal thread mounting cylinder 16. When the internal thread mounting cylinder 16 is screwed in place, it is in contact with the first convex connecting plate 14, which forms a relatively airtight space in the internal thread mounting cylinder 16, which can effectively prevent water vapor from entering and ensure the stability and reliability of the electrical connection part. The second anchoring flange 22 is fixedly installed with a second hollow mounting cylinder 23. At this time, the left side will also complete the relative steps, the first convex connecting plate 14 is inserted into the first hollow mounting cylinder 11, and then the right internal thread connecting cylinder 17 is rotated counterclockwise, the internal thread connecting cylinder 17 interacts with the thread on the side wall of the first hollow mounting cylinder 11, and during the rotation process, the internal thread connecting cylinder 17 drives the right tapered extrusion cylinder 25 to move from right to left. Since the tapered extrusion cylinder 25 is fixedly installed with the internal thread connecting cylinder 17, and the right tapered limiting plate 19 is fixed at the end of the tapered connecting cylinder 18 away from the first hollow mounting cylinder 11, the tapered extrusion cylinder 25 will slide on the side wall of the right tapered limiting plate 19, and as the tapered extrusion cylinder 25 moves, the right tapered limiting plate 19 exerts an extrusion force on the right cable, thereby clamping the right cable, and at this time, the excess cable is located in the tapered connecting cylinder 18. The first full thread cylinder 13 is inserted into the first hollow mounting cylinder 11 and the second hollow mounting cylinder 23. Then the second concave connecting plate 24 is inserted into the second hollow mounting cylinder 23, and then the left internal thread connecting cylinder 17 is rotated counterclockwise, and similarly, the left internal thread connecting cylinder 17 drives the left tapered extrusion cylinder 25 to move from left to right, the left tapered extrusion cylinder 25 slides on the side wall of the left tapered limiting plate 19, and the left tapered limiting plate 19 clamps the left cable, thereby completing the fixation of the two end cables.The left side wall of the first full thread barrel 13 is fixedly provided with a second concave connecting plate 24, and at this time, the first convex connecting plate 14 is inserted into the second concave connecting plate 24, which further enhances the connection between the two first full thread barrels 13. At the same time, with the insertion of the first convex connecting plate 14, the first anchor flange 12 is correspondingly inserted into the second anchor flange 22, so that the second anchor flange 22 and the first anchor flange 12 are closed, and the first anchor flange 12 and the second anchor flange 22 are fixedly arranged on the side wall of the first hollow mounting barrel 11 and the second hollow mounting barrel 23, respectively. Their closure connects the two main mounting barrels into a whole, enhancing the stability of the whole cable joint structure. Then the first anchor flange 12 and the second anchor flange 22 are connected together through bolts, further improving the connection strength, ensuring that the whole cable joint can withstand various external forces, and meeting the operation requirements of corrosion-resistant high-voltage cables in various complex environments. The right side wall of the first full thread barrel 13 is fixedly provided with a first convex connecting plate 14, a second concave connecting plate 24 is inserted into the second hollow mounting barrel 23, the first convex connecting plate 14 is inserted into the first hollow mounting barrel 11, the first convex connecting plate 14 is inserted into the second concave connecting plate 24, and the two first full thread barrels 13 are threadedly provided with external threaded mounting columns 15, and the side walls of the two first full thread barrels 13 are threadedly provided with internal threaded mounting barrels 16. The side walls of the first hollow mounting barrel 11 and the second hollow mounting barrel 23 are threadedly provided with internal threaded connecting barrels 17, the side walls of the two internal threaded connecting barrels 17 are fixedly provided with tapered extrusion barrels 25, the ends of the first hollow mounting barrel 11 and the second hollow mounting barrel 23 away from the first anchor flange 12 and the second anchor flange 22 are fixedly provided with tapered connecting barrels 18, the ends of the two tapered connecting barrels 18 away from the first hollow mounting barrel 11 and the second hollow mounting barrel 23 are fixedly provided with tapered limiting plates 19, and the interiors of the two tapered connecting barrels 18 are fixedly provided with expansion rubber sheets 21. After the cable joint is installed and put into use, under the influence of external environmental factors such as temperature change and humidity change, the expansion rubber sheets 21 will expand to a certain extent. This expansion can further fill the gap between the interior of the tapered connecting barrel 18 and the cable, enhance the sealing effect, prevent harmful substances such as water vapor and corrosive gas from the outside from invading the interior of the cable joint, protect the electrical connection components and insulation components inside from erosion, and prolong the service life of the cable joint. Through the closed space formed by the internal threaded mounting barrel 16 and the first convex connecting plate 14, the filling of the gap in the interior of the tapered connecting barrel 18 by the expansion rubber sheet 21, and the close connection between the components, the whole cable joint forms a relatively sealed structure, ensuring that the electrical performance inside is not disturbed by external factors during the long-term operation of the high-voltage cable, and ensuring the safe and stable operation of the high-voltage cable.

[0035] Working principle: align the outer threaded mounting column 15 connected with the cable end with the first full threaded cylinder 13, and then rotate the outer threaded mounting column 15 counterclockwise. Because the first full threaded cylinder 13 has a threaded structure that matches the outer threaded mounting column 15, the outer threaded mounting column 15 can gradually rotate into the first full threaded cylinder 13 through this threaded connection. This connection not only provides mechanical fastening, but more importantly, ensures the continuity of the electrical connection path between the cables. Because stable electrical connection is crucial during the operation of high-voltage cables, any poor contact can cause increased resistance, heating, or even electrical accidents. Through this tight threaded connection, it ensures smooth transmission of current between the two cables;

[0036] After rotating the outer threaded mounting column 15 into the first full threaded cylinder 13, then align the first full threaded cylinder 13 with the inner threaded mounting cylinder 16, and rotate the inner threaded mounting cylinder 16 counterclockwise. The threads inside the inner threaded mounting cylinder 16 interact with the threads on the side wall of the first full threaded cylinder 13, allowing the first full threaded cylinder 13 to rotate into the inner threaded mounting cylinder 16. When the inner threaded mounting cylinder 16 is rotated into place, it comes into contact with the first convex connecting plate 14. This contact forms a relatively airtight space inside the inner threaded mounting cylinder 16, which effectively prevents water vapor from entering. Because in the operating environment of high-voltage cables, the intrusion of water vapor can cause conductor corrosion, insulation performance degradation, and other problems, affecting the normal operation and service life of the cable. Through the formation of this airtight space, the stability and reliability of the electrical connection part are ensured to some extent;

[0037] After completing the right side electrical connection related steps, insert the first convex connecting plate 14 into the first hollow mounting cylinder 11, and then rotate the right side inner threaded connecting cylinder 17 counterclockwise. The inner threaded connecting cylinder 17 interacts with the threads on the side wall of the first hollow mounting cylinder 11. During rotation, the inner threaded connecting cylinder 17 drives the right side conical extrusion cylinder 25 to move from right to left. Because the conical extrusion cylinder 25 is fixedly installed with the inner threaded connecting cylinder 17, and the right side conical limiting plate 19 is fixed at the end of the conical connecting cylinder 18 away from the first hollow mounting cylinder 11, the conical extrusion cylinder 25 will slide on the side wall of the right side conical limiting plate 19. With the movement of the conical extrusion cylinder 25, the right side conical limiting plate 19 exerts a squeezing action on the right side cable, thereby clamping the right side cable. At this time, the excess cable part will be located inside the conical connecting cylinder 18. This design not only effectively fixes the cable to prevent it from loosening during operation and affecting electrical connection, but also stores the excess cable, making the entire structure more compact;

[0038] After the right cable fixation is completed, the corresponding operation is performed on the left side. The second concave connecting plate 24 is inserted into the second hollow mounting cylinder 23, and then the left internal threaded connecting cylinder 17 is rotated counterclockwise. Similarly, the left internal threaded connecting cylinder 17 drives the left conical extrusion cylinder 25 to move from left to right. The left conical extrusion cylinder 25 slides on the side wall of the left conical limiting plate 19, and the left conical limiting plate 19 clamps the left cable. The fixation of the left cable is completed. Through the symmetrical operation of both sides, the two cables are firmly fixed at both ends of the cable joint, ensuring that the cables can be stably maintained inside the joint during the operation of the high-voltage cable, and displacement or loosening phenomenon does not occur, ensuring the stability and reliability of the electrical connection;

[0039] After the fixation of the two ends of the cable is completed, the first convex connecting plate 14 is inserted into the second concave connecting plate 24. This insertion action further strengthens the connection between the two first full-threaded cylinders 13, making the entire cable joint more stable in electrical connection and mechanical connection. At the same time, the first anchoring flange 12 is inserted into the second anchoring flange 22 with the insertion of the first convex connecting plate 14, so that the second anchoring flange 22 and the first anchoring flange 12 are closed. The first anchoring flange 12 and the second anchoring flange 22 are fixed on the side wall of the first hollow mounting cylinder 11 and the second hollow mounting cylinder 23, respectively. Their closure connects the two main mounting cylinder parts into a whole, enhancing the stability of the entire cable joint structure.

[0040] After the first anchoring flange 12 and the second anchoring flange 22 are closed, they are connected together by bolts. The bolt connection further improves the connection strength between the two flanges, ensuring that the entire cable joint can withstand various external forces such as tension and vibration during the operation of the high-voltage cable, without separation or loosening phenomenon. This multi-step, multi-level connection and fastening method, from electrical connection to mechanical fixation, comprehensively guarantees the reliability and stability of the high-voltage cable joint, enabling it to meet the operation requirements of corrosion-resistant high-voltage cables in various complex environments.

[0041] The role of the expansion rubber sheet: The expansion rubber sheet 21 is fixed and installed in both conical connecting cylinders 18. The expansion rubber sheet 21 plays an important role in the sealing and protection of the entire cable joint. After the cable joint is installed and put into use, under the influence of external environmental factors such as temperature changes and humidity changes, the expansion rubber sheet 21 will expand to a certain extent. This expansion can further fill the gap between the conical connecting cylinder 18 and the cable, enhancing the sealing effect and preventing harmful substances such as water vapor and corrosive gases from entering the inside of the cable joint, thereby protecting the internal electrical connection components and insulation components from erosion and prolonging the service life of the cable joint.

[0042] The closed space formed by the female threaded mounting cylinder 16 and the first convex connecting plate 14, the filling of the gap inside the tapered connecting cylinder 18 by the expanded rubber sheet 21, and the close connection between the components, form a relatively sealed structure for the whole cable joint, which can effectively resist the influence of the external harsh environment, ensure that the internal electrical performance is not disturbed by external factors during the long-term operation of the high-voltage cable, and ensure the safe and stable operation of the high-voltage cable.

[0043] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
