Flexible stretchable grounding device

Abstract

A flexible, stretchable grounding device, belonging to the field of marine technology, includes a grounding structure with connecting shafts at both ends. The grounding structure comprises two sleeves, with a braided wiring strip placed between them. Wire ends are fixedly installed at both ends of the braided wiring strip, and a fixing pad is fixedly installed inside the sleeves. The connecting shafts are fixed between the equipment body and the ship structure using bolts and tightened. Since the sleeves are made of multiple single-wire braids, they have a certain degree of tensile strength, allowing for some displacement when connecting the equipment body and the ship structure. This avoids the possibility of the yellow-green grounding wire breaking off from the equipment body or ship structure without requiring sufficient displacement margin. Furthermore, its surface is coated with a tin-zinc anti-corrosion coating, ensuring conductivity, tensile strength, and good corrosion resistance.

Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a flexible and stretchable grounding device. Background Technology

[0002] In floating production facilities, marine engineering products, and civilian ship projects, all parts of the ship, including brackets, pipes, ventilation ducts, railings, handrails, ladders, and other metal materials (which may have induced electromotive force in some cases), need to be effectively grounded for safety. Under normal circumstances, yellow-green grounding wires are used for safety grounding. This grounding method requires two additional copper connectors to be installed at both ends of the yellow-green grounding wire for connection between the equipment body and the hull. This yellow-green grounding wire is also used for grounding some locally displaced equipment.

[0003] Currently, because yellow-green grounding wires are inflexible and non-stretchable, over time they may break off from the equipment or ship structure, posing a safety hazard and potentially causing accidents. To address these shortcomings, this invention designs a flexible and stretchable grounding device. Summary of the Invention

[0004] This invention provides a flexible and stretchable grounding device, which has the advantage of avoiding the disconnection of the yellow-green grounding wire from the equipment body or ship structure, and solves the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a flexible and stretchable grounding device, comprising a grounding structure, wherein a connecting shaft structure is provided at both ends of the grounding structure; the grounding structure includes two sleeve blocks, a braided wiring strip is placed between the two sleeve blocks, wire ends are fixedly installed at both ends of the two braided wiring strips, a fixing pad is fixedly installed in the inner cavity of the two sleeve blocks, an installation groove is opened at the end of the two wire ends, a first pressure plate is fixedly installed inside the two installation grooves, and the outer surface of the braided wiring strip is coated with a tin-zinc anti-corrosion coating.

[0006] As a preferred embodiment of the present invention, the two first pressure plates are internally fitted with quick-release structures, and the two quick-release structures include bottom cover plates.

[0007] As a preferred embodiment of the present invention, a first column is fixedly installed on the top of the two bottom cover plates, and a rotating rod is slidably installed inside the first column, the rotating rod being rotatably connected to the first column.

[0008] As a preferred embodiment of the present invention, a top cover plate is fixedly installed on the top of the rotating rod, and a first rotating handle is fixedly installed on the top of the top cover plate. The first rotating handle is a rubber product.

[0009] As a preferred embodiment of the present invention, a retaining ring plate is fixedly installed at the bottom of the top cover plate, and a threaded rod is installed on the internal thread of the top cover plate.

[0010] As a preferred embodiment of the present invention, a second throttle is fixedly installed on the top of the threaded rod, and the second throttle is a rubber product.

[0011] As a preferred embodiment of the present invention, a second column is fixedly installed on the top of the bottom cover plate, and the second column has a threaded groove inside.

[0012] As a preferred embodiment of the present invention, the two connecting shafts include collars, and the two collars are rotatably connected to the first column.

[0013] As a preferred embodiment of the present invention, side rods are fixedly installed on both sides of the outer surfaces of the two collars, and anti-slip side plates are fixedly installed on one side of the outer surfaces of the two side rods.

[0014] As a preferred embodiment of the present invention, a sleeve rod is fixedly installed between the two side rods, a rotating shaft is rotatably installed on the outer surface of the two sleeve rods, a second pressure plate is fixedly installed on one side of the two rotating shafts, and a fixing bolt is placed inside the two second pressure plates.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This flexible and stretchable grounding device, through its grounding structure, connects the hull to two devices for grounding. The connecting shaft structure is fixed between the device body and the hull structure by fixing bolts and tightening. Since the sleeve is made of multiple single wires and has a certain range of tensile capacity, it allows a certain displacement when connecting the device body and the hull structure. This achieves the goal of avoiding the situation where the yellow-green grounding wire is disconnected from the device body or the hull structure without leaving sufficient displacement margin. At the same time, its surface is coated with tin and zinc anti-corrosion coatings to ensure conductivity, tensile performance and strength while also having good corrosion resistance.

[0017] 2. This flexible and stretchable grounding device, through a quick-release structure, allows for temporary cancellation of the grounding state after grounding is completed. At this time, rotating the second handle causes the threaded rod to rotate inside the top cover plate and move upward, thereby disengaging the threaded rod from the thread groove. Then, pulling the rotating rod upward pulls the top cover plate and the retaining ring plate out from inside the second column. At this time, rotating the first handle causes the top cover plate to rotate to one side, allowing the first pressure plate to be removed from the outer surface of the second column. This cancels the grounding state and improves the flexibility of the device.

[0018] 3. This flexible and stretchable grounding device, through a coupling structure, allows the collar to rotate on the outer surface of the first column and the rotating shaft to rotate on the outer surface of the sleeve in the grounding state. Thus, when the second pressure plate is connected to the hull or the main body of the equipment, the rotation of the rotating shaft and the collar allows the grounding device to maintain conductive continuity when the ship is rocking.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7A flexible and stretchable grounding device includes a grounding structure 1 with a connecting shaft structure 3 at both ends. The grounding structure 1 includes two sleeve blocks 101, with a braided wiring strip 102 placed between the two sleeve blocks 101. Wire ends 104 are fixedly installed at both ends of the two braided wiring strips 102. Fixing pads 103 are fixedly installed in the inner cavity of the two sleeve blocks 101. Mounting grooves 105 are opened at the ends of the two wire ends 104. First pressure plates 106 are fixedly installed inside the two mounting grooves 105. The outer surface of the braided wiring strip 102 is coated with a tin-zinc anti-corrosion coating.

[0029] Please see Figure 4-6 The two first pressure plates 106 are internally fitted with quick-release structures 2, each including a bottom cover plate 21. A first column 22 is fixedly mounted on the top of each bottom cover plate 21. A rotating rod 24 is slidably mounted inside the first column 22 and is rotatably connected to the first column 22. A top cover plate 25 is fixedly mounted on the top of the rotating rod 24, and a first handle 26, made of rubber, is fixedly mounted on the top of the top cover plate 25. A retaining ring plate 27 is fixedly mounted on the bottom of the top cover plate 25, and a threaded rod 28 is threaded inside the top cover plate 25. A second handle 29, also made of rubber, is fixedly mounted on the top of the threaded rod 28. A second column 23, also made of rubber, is fixedly mounted on the top of the bottom cover plate 21. A threaded groove 210 is formed inside the second column 23.

[0030] If the power connection needs to be temporarily canceled, turn the second handle 29 to make the threaded rod 28 rotate inside the top cover plate 25 and move upward, thereby disengaging the threaded rod 28 from the thread groove 210. Then, pull the rotating rod 24 upward to pull the top cover plate 25 and the retaining ring plate 27 out from inside the second column 23. Then, turn the first handle 26 to rotate the top cover plate 25 to one side, and the first pressure plate 106 can be removed from the outer surface of the second column 23. At this time, the grounding state can be canceled.

[0031] Please see Figure 4-7 The two connecting structures 3 include collars 31, which are rotatably connected to the first column 22. Side rods 32 are fixedly installed on both sides of the outer surface of the two collars 31, and anti-slip side plates 33 are fixedly installed on one side of the outer surface of the two side rods 32. A sleeve rod 34 is fixedly installed between the two side rods 32, and a rotating shaft 35 is rotatably installed on the outer surface of the two sleeve rods 34. A second pressure plate 36 is fixedly installed on one side of the two rotating shafts 35, and a fixing bolt 37 is placed inside the two second pressure plates 36.

[0032] The collar 31 can rotate on the outer surface of the first column 22, and the rotating shaft 35 can rotate on the outer surface of the sleeve 34. Thus, when the second pressure plate 36 is connected to the hull or the main body of the equipment, the rotatability of the rotating shaft 35 and the collar 31 allows the grounding device to maintain electrical continuity when the ship is rocking.

[0033] Working principle: When a flexible and stretchable grounding device is used, firstly, two first pressure plates 106 are fitted onto the outer surface of the second column 23. Then, the second pressure plate 36 is fixed between the equipment body and the ship structure using fixing bolts 37 and tightened. At this time, since the sleeve 101 is made of multiple single wires braided together, it has a certain range of tensile capacity. Therefore, when connecting the equipment body and the ship structure, it is allowed to have a certain displacement. This achieves the goal of avoiding the situation where the yellow-green grounding wire is disconnected from the equipment body or ship structure without leaving sufficient displacement margin. At the same time, its surface is coated with tin and zinc anti-corrosion coating to ensure conductivity, tensile performance, and strength while also having good corrosion resistance. Meanwhile, the collar 31 can be used to secure the first column 22. The outer surface can rotate, and the rotating shaft 35 can rotate on the outer surface of the sleeve 34. Thus, when the second pressure plate 36 is connected to the hull or the main body of the equipment, the rotation of the rotating shaft 35 and the collar 31 allows the grounding device to maintain electrical continuity when the ship is rocking. Finally, if it is necessary to temporarily cancel the grounding state, the second handle 29 is turned to drive the threaded rod 28 to rotate inside the top cover plate 25 and move upward, thereby disengaging the threaded rod 28 from the thread groove 210. At this time, the rotating rod 24 is pulled upward to pull the top cover plate 25 and the retaining ring plate 27 out from inside the second column 23. Then, the first handle 26 is turned to rotate the top cover plate 25 to one side, and the first pressure plate 106 can be removed from the outer surface of the second column 23, thus canceling the grounding state.
