Description

Technical Field

[0001] This invention relates to the field of petroleum engineering, and more specifically to a marine petroleum engineering equipment. Background Technology

[0002] Photoelectric connectors are used on various deep-sea equipment in fields such as petroleum engineering. Unlike the surface environment, the deep-sea environment is characterized by high pressure, high salinity, and high humidity. The stability, continuity, and insulation reliability of the photoelectric connectors in the deep-sea environment are crucial for successful production. Testing various photoelectric connectors in the deep-sea environment can prevent problems such as structural, sealing, and pressure resistance issues from affecting product use.

[0003] In the past, people generally tested photoelectric connectors through actual sea trials, but actual sea trials have disadvantages such as high cost, high risk, long cycle and difficulty in repeated testing, and this testing method has been gradually phased out.

[0004] Later, some proposed simulating the deep-sea environment in a high-pressure sealed tank (or underwater high-pressure chamber) and then conducting photoelectric plug-in connection tests within the high-pressure tank. This method avoids the shortcomings of actual sea trials and has gradually become the main method for deep-sea wet plug-in photoelectric connection testing. However, this method also has certain drawbacks. For example, the material opening and cover plate of the high-pressure chamber are sealed with bolts. On the one hand, the cover plate and material opening cannot be opened and closed quickly, leading to a prolonged test period. On the other hand, when the number of bolt holes connecting the two is small, the excessive pressure inside the high-pressure chamber will affect the sealing performance between the cover plate and the material opening of the chamber. Conversely, when the number of bolt holes connecting the two is large, it will reduce the strength of the corresponding parts. Without replacing with higher-strength materials, it is also not conducive to maintaining the high-pressure environment inside the high-pressure chamber.

[0005] Furthermore, existing technologies for testing photoelectric connectors involve connecting two connectors (male and female) and placing them directly inside a high-pressure chamber, which cannot simulate the conditions after repeated insertions and removals in a deep-sea environment. Summary of the Invention

[0006] To address the issues of the underwater high-pressure chamber cover's inability to quickly open and close the material opening, the insufficient pressure-bearing capacity of the bolted connection between the high-pressure chamber cover and the material opening, and the inability of the photoelectric connector to be plugged in and unplugged in a simulated environment, this invention provides a simulation system for a photoelectric connector. The technical solution adopted is as follows: A deep-sea wet-plugging optoelectronic connector simulation system includes a high-pressure chamber, in which a plugging assembly is placed. The high-pressure chamber includes a chamber body with a material opening. A sealing ring surrounds the material opening on the outer wall of the chamber body. A cover plate covers the material opening, and the edge of the cover plate fits against the sealing ring to form a sealing joint. A locking mechanism is mounted on the sealing joint. The key feature is that the locking mechanism includes a clamp, which is mounted on a moving mechanism. The moving mechanism moves the clamp closer to or away from the sealing joint. The clamp has a sealing groove facing the sealing joint. When the clamp approaches the sealing joint, the sealing joint is embedded in the sealing groove. The plug-in assembly includes a plug-in fixed part and a plug-in movable part. A telescopic mechanism is connected between the plug-in fixed part and the plug-in movable part. The telescopic mechanism drives the plug-in movable part to move closer to or away from the plug-in fixed part. The plug-in fixed part and the plug-in movable part are respectively provided with plug heads.

[0007] Using the above technical solution, the clamp is configured on the moving mechanism, which moves it closer to or away from the docking sealing part. When the moving mechanism moves the clamp closer to the docking sealing part, the docking sealing part is embedded in the sealing groove, pressing the edge of the cover plate and the cabin sealing ring together, thereby quickly closing the material opening. When the moving mechanism moves the clamp away from the docking sealing part, the docking sealing part disengages from the sealing groove, loosening the edge of the cover plate and the cabin sealing ring, thereby quickly opening the material opening. At the same time, the clamp and the docking sealing part are in continuous contact without the need for openings, which does not reduce the strength of the connection and provides good pressure resistance. The insertion and removal fixing part and the insertion and removal moving part cooperate with each other to allow the photoelectric insertion and removal head to be inserted and removed inside the cabin, simulating the stability test of the photoelectric insertion and removal head after multiple insertions and removals in a deep-sea environment.

[0008] As a preferred technical solution, the insertion / removal fixing part is fixed to the cover plate by a connecting rod. A telescopic guide assembly connects the insertion / removal fixing part and the insertion / removal movable part. The fixing part of the telescopic mechanism is fixedly connected to the insertion / removal fixing part, and the movable part of the telescopic mechanism is fixedly connected to the insertion / removal movable part. The insertion / removal fixing part is provided with a first insertion / removal head, and the insertion / removal movable part is provided with a second insertion / removal head. The first and second insertion / removal heads are aligned along the telescopic direction of the telescopic mechanism. With this structure, the first and second insertion / removal heads can be stably inserted / removed within the hyperbaric chamber.

[0009] As a preferred technical solution, the locking mechanism includes at least two clamps, which are configured to be close to or far from each other. Multiple clamps can approach or move away from the mating sealing portion from multiple directions, increasing stability after multi-directional locking and allowing for faster opening and closing of the material opening through multi-directional unlocking.

[0010] As a preferred technical solution, the multiple clamps are configured to move closer to each other synchronously or move further away from each other synchronously. The synchronous movement of multiple clamps ensures consistent opening and closing rhythms and provides a basic guarantee that each clamp simultaneously contacts or disengages from the sealing part. This ensures balanced and uniform force distribution on the edge of the cover plate, preventing it from warping.

[0011] As a preferred technical solution, the cover plate includes a cover plate sealing ring and a cover body. The cover plate sealing ring is disposed around the cover body, and the cover plate sealing ring and the cover body maintain a relatively fixed relationship. The cover plate sealing ring and the cabin sealing ring are mated and fitted together to form the mating seal portion. The outer end face of the cover plate sealing ring is fitted with the inner wall of one groove of the sealing groove, and the outer end face of the cabin sealing ring is fitted with the inner wall of the other groove of the sealing groove. This design, with its cover plate sealing ring, facilitates mating with the cabin sealing ring and also facilitates the connection and nesting of the clamp with the mating seal portion.

[0012] As a preferred technical solution, both inner walls of the sealing groove are inclined, and the inner walls of the sealing groove gradually expand outward from the bottom to the opening. The outer end faces of the cover plate sealing ring and the cabin sealing ring are both inclined surfaces, and they respectively fit against the inner walls of the corresponding grooves of the sealing groove. When the clamp approaches the docking sealing part, the cover plate sealing ring and the cabin sealing ring are squeezed together by the inner walls of the sealing groove. With the above structure, the clamp contacts the docking sealing part (specifically: the cover plate sealing ring and the cabin sealing ring) through the inner walls of the inclined sealing groove, squeezing and locking them. During the process of embedding the sealing groove into the docking sealing part, the cover plate sealing ring and the cabin sealing ring are gradually pressed together to achieve a rapid and tight contact and a sealing effect. At the same time, during the process of the sealing groove disengaging from the docking sealing part, the cover plate sealing ring and the cabin sealing ring are gradually loosened.

[0013] As a preferred technical solution, the cover sealing ring includes a cover compression ring and a cover connecting portion. The cover connecting portion connects the inner ring of the cover compression ring to the cover body. The thickness of the cover connecting portion is less than the thickness of the cover compression ring and the cover body. The outer end face of the cover compression ring fits against the inner wall of the corresponding groove of the sealing slot. The relatively small thickness of the cover connecting portion makes it relatively easy to undergo elastic deformation. During the process of the cover sealing ring compressing the cabin sealing ring, the outer ring of the cover compression ring is more likely to make tight contact with the cabin sealing ring.

[0014] As a preferred technical solution, the cover plate connecting part is annular, and the cover plate connecting part and the cover plate extrusion ring are arranged along the same center line. The inner end face of the annular cover plate connecting part transitions linearly with the inner end face of the cover plate extrusion ring, and the outer end face of the annular cover plate connecting part has an arc-shaped groove structure. This structure of the cover plate connecting part is relatively easy to process, and the arc-shaped groove structure of the outer end face of the annular cover plate connecting part can avoid stress concentration and breakage of the cover plate connecting part.

[0015] As a preferred technical solution, the chamber sealing ring includes a chamber compression ring, a connecting transition portion, and a chamber connecting portion. The chamber connecting portion is disposed around the material opening on the outer wall of the chamber. The chamber compression ring is disposed around the chamber connecting portion. The connecting transition portion is located between the chamber compression ring and the chamber connecting portion and fixes the two together. The thickness of the connecting transition portion is less than the thickness of the chamber compression ring, and the thickness of the connecting transition portion is less than the thickness of the chamber connecting portion. The outer end face of the chamber compression ring fits against the inner wall of the groove corresponding to the sealing slot.

[0016] The thickness of the connecting transition section is relatively small, making it relatively easy to undergo elastic deformation. During the process of the cabin sealing ring squeezing the cover plate sealing ring, the cabin squeezing ring located on the outer ring is more likely to make close contact with the cover plate sealing ring.

[0017] As a preferred technical solution, the connecting transition portion is annular, and is arranged along the same centerline as the chamber extrusion ring. The inner end face of the annular connecting transition portion transitions linearly with the inner end face of the chamber extrusion ring, and the outer end face of the annular connecting transition portion has an arc-shaped groove structure. This structure makes the connecting transition portion relatively easy to process, and the arc-shaped groove structure of the outer end face of the annular connecting transition portion can prevent stress concentration and breakage.

[0018] As a preferred technical solution, a deformation gap is provided between the cabin compression ring and the cover plate compression ring to provide deformation redundancy during the mutual compression process.

[0019] As a preferred technical solution, the two inner walls of the sealing slot are respectively provided with arc-shaped stress grooves at the connection between them and the bottom surface of the slot. The function and effect of the arc-shaped stress grooves are the same as those of the arc-shaped groove structure on the outer end face of the cover plate connection part and the arc-shaped groove structure on the outer end face of the connection transition part. They can reduce the thickness at the corresponding position to allow for elastic deformation and reduce the stress concentration of the material at the corresponding position.

[0020] As a preferred technical solution, the moving mechanism is a linear moving mechanism. Using a linear moving mechanism for telescopic and push-pull clamps offers advantages such as simple structure and stability.

[0021] As a preferred technical solution, there are two clamps, which are arranged opposite each other, and the mating sealing portion is located between the two clamps. The two clamps connect to the mating sealing portion from both sides, which has the advantage of high connection efficiency.

[0022] As a preferred technical solution, the linear motion mechanism includes a bidirectional screw with a first threaded section and a second threaded section. The threads of the first and second threaded sections have opposite directions of rotation. The first threaded section is threadedly assembled with one of the clamps, and the second threaded section is threadedly assembled with the other clamp. When the bidirectional screw rotates in both directions, it drives the two clamps to move closer or further apart. Using this technical solution, two clamps are simultaneously driven to move synchronously closer or further apart by the same screw with different directions of rotation, which has the advantages of simple structure and high synchronization. Furthermore, the bidirectional screw has a certain self-locking effect after being threadedly assembled with the clamps, which can prevent uncontrolled movement of the clamps.

[0023] As a preferred technical solution, a nut seat is fixed to the outer wall of the clamp, and the bidirectional screw is threadedly assembled with the nut seat. The nut seat is located on the outer wall of the clamp for easy adjustment and assembly.

[0024] As a preferred technical solution, there are two bidirectional screws arranged parallel to each other, and both clamps are located between the two bidirectional screws. The two bidirectional screws simultaneously drive the two clamps, offering the advantage of high stability.

[0025] As a preferred technical solution, the two bidirectional screws are driven to rotate by the same motor assembly. This solution can improve the rotational synchronization of the two bidirectional screws.

[0026] As a preferred technical solution, the motor assembly includes a motor and two reducers. One reducer is mounted at the end of each of the bidirectional screws, and the input ends of the two reducers are connected to the same motor. This solution enables the bidirectional screws to rotate synchronously at a slower speed.

[0027] As a preferred technical solution, the system also includes a clamp-assisted movement component, wherein the clamp is mounted on the clamp-assisted movement component and moves linearly along it. This solution can reduce the load on the bidirectional screw and avoid affecting the adjustment accuracy of the bidirectional screw.

[0028] As a preferred technical solution, the clamp auxiliary moving component includes a linear guide rail parallel to the bidirectional screw, and a moving roller is mounted on the clamp, which travels along the linear guide rail. This clamp auxiliary moving component has high load-bearing capacity and a simple structure.

[0029] As a preferred technical solution, the linear guide rail and the bidirectional screw are horizontally arranged, and the clamp moves linearly in the horizontal direction. This structure can prevent the weight of the clamp from affecting the adjustment accuracy of the bidirectional screw. Attached Figure Description

Detailed Implementation

The first insertion head 91 and the second insertion head 81 are aligned along the telescopic direction of the telescopic mechanism 7. When the movable part of the telescopic mechanism 7 moves the insertion and removal movable part 8 closer to the insertion and removal fixing part 9, the first insertion head 91 and the second insertion head 81 are engaged. When the movable part of the telescopic mechanism 7 moves the insertion and removal movable part 8 away from the insertion and removal fixing part 9, the first insertion head 91 and the second insertion head 81 are disengaged.

[0035] Both the insertion / removal movable part 8 and the insertion / removal fixed part 9 are plate-shaped structures. The telescopic mechanism 7 is preferably a hydraulic cylinder. The telescopic guide assembly consists of multiple parallel telescopic guide rods. One end of each telescopic guide rod is fixed to the insertion / removal fixed part 9. The telescopic guide rod is movably inserted through the insertion / removal movable part 8. The length direction of the telescopic guide rod is consistent with the telescopic direction of the hydraulic cylinder.

[0036] The cover plate 2 is provided with several universal through holes. The connecting rod, the hydraulic oil line of the hydraulic cylinder, the line of the first plug-in head, and the line of the second plug-in head all extend out of the high-pressure chamber A through the universal through holes. Of course, a seal needs to be installed in the universal through holes.

[0037] The cabin 1 is equipped with a liquid inlet and a liquid outlet on its walls. By injecting seawater into the cabin 1 and maintaining pressure, the deep-sea environment at different depths can be simulated.

[0038] Lifting lugs are provided on the clamp 3, the cover plate 2 and the cabin 1 respectively to facilitate hoisting.

[0039] One specific implementation is that the locking mechanism includes at least two clamps 3, and the plurality of clamps 3 are configured to be close to or far from each other.

[0040] Furthermore, another more specific implementation is that the plurality of said clamps 3 are configured to move closer to each other synchronously or move further away from each other synchronously.

The inner side of the cover body 22 is provided with a blocking part, which is inserted into the cabin sealing ring 11. A radial seal is provided between the inner wall of the cabin sealing ring 11 and the blocking part.

[0042] The cover sealing ring 21 and the cabin sealing ring 11 are mated together to form the mating seal. An axial seal is provided between the cover sealing ring 21 and the cabin sealing ring 11. The outer end face of the cover sealing ring 21 is mated with the inner wall of one groove of the sealing groove 3a, and the outer end face of the cabin sealing ring 11 is mated with the inner wall of the other groove of the sealing groove 3a.

[0043] Both inner walls of the sealing groove 3a are inclined, and the inner walls of the sealing groove 3a gradually expand outward from the bottom to the opening. The outer end face of the cover sealing ring 21 and the outer end face of the cabin sealing ring 11 are both inclined surfaces. The outer end face of the cover sealing ring 21 and the outer end face of the cabin sealing ring 11 respectively fit against the inner wall of the corresponding groove of the sealing groove 3a. When the clamp 3 approaches the docking sealing part, the cover plate sealing ring 21 and the cabin sealing ring 11 are squeezed together by the inner wall of the sealing groove 3a; and the closer they are, the tighter they are pressed.

[0044] The cover sealing ring 21 includes a cover compression ring 211 and a cover connecting part 212. The cover connecting part 212 is connected between the inner ring of the cover compression ring 211 and the cover body 22. The thickness of the cover connecting part 212 is less than the thickness of the cover compression ring 211 and the thickness of the cover body 22. The outer end face of the cover compression ring 211 is in contact with the inner wall of the groove corresponding to the sealing groove 3a.

The bidirectional screw 41 has a first threaded section and a second threaded section, which are axially distributed and have opposite thread directions. The first threaded section is threadedly assembled with one of the clamps 3, and the second threaded section is threadedly assembled with the other clamp 3.
