However, hydraulic power systems are difficult to troubleshoot once a malfunction occurs, usually requiring an emergency operation mode to control specific actions for emergency handling and prevent further losses. Existing technologies often utilize external pipelines to provide power for certain actions in emergency situations. However, disassembling the hydraulic pipelines of some power components is extremely cumbersome, making it impractical in the complex underwater environment, and the cumbersome process significantly reduces the efficiency of emergency operations. Utility Model Content
[0003] One objective of this invention is to provide an emergency operation device that simplifies the emergency operation procedures of hydraulic control valve groups and improves emergency operation efficiency.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] An emergency operation device is provided, including an operating component, an adapter plate, and a fixing plate located on the outside of a sealed chamber. The fixing plate is connected to the outer wall of the sealed chamber. The adapter plate has a threaded hole, and the operating component is screwed into the threaded hole. The position of the operating component relative to the fixing plate remains unchanged.
[0006] The emergency operation device also includes a guide rod and a trigger located inside the sealed chamber. One end of the guide rod is connected to the adapter plate. The guide rod passes through the through hole of the fixing plate and the through hole of the sealed chamber in sequence. The other end of the guide rod is snapped into the trigger.
[0007] When the operating component rotates, the adapter plate can drive the guide rod to move toward the sealed chamber, so that the trigger can move toward the emergency contact of the hydraulic control valve assembly until it presses against the emergency contact.
[0008] Optionally, a first limiting groove is provided on the end face of the fixing plate facing the operating member, and one end of the operating member is located in the first limiting groove.
[0009] Optionally, the adapter plate has a first through hole, and the emergency operation device also includes a nut, with one end of the guide rod passing through the first through hole and screwed to the nut.
[0010] Optionally, a second limiting groove is provided at the opening of the first through hole facing the operating member, and the nut is located in the second limiting groove.
[0011] Optionally, it also includes a sealing ring, which is sleeved on the guide rod and sandwiched between the fixing plate and the outer wall of the sealing chamber.
[0012] Optionally, a third limiting groove is provided on the end face of the fixing plate facing the sealed chamber, and the sealing ring is located in the third limiting groove.
[0013] Optionally, the trigger has a second through hole, the inner wall of the second through hole has a stepped surface, the stepped surface is disposed away from the operating member, the guide rod passes through the second through hole, and the other end of the guide rod abuts against the stepped surface.
[0014] Optionally, it also includes an elastic element, which is sleeved on the guide rod and has a tendency to press the end against the stepped surface.
[0015] Optionally, it also includes an auxiliary plate located between the trigger and the inner wall of the sealed chamber. The auxiliary plate has a third through hole, and a fourth limiting groove is formed at the opening of the third through hole facing the trigger. The guide rod passes through the third through hole, and the elastic element is partially located in the fourth limiting groove. One end of the elastic element abuts against the bottom of the fourth limiting groove, and the other end abuts against the trigger.
[0016] Another objective of this invention is to provide an underwater hydraulic system that simplifies emergency operation procedures for hydraulic control valve groups and improves emergency operation efficiency.
[0017] To achieve this objective, the present invention adopts the following technical solution:
[0018] An underwater hydraulic system is provided, comprising a sealed chamber, a hydraulic control valve assembly, and the aforementioned emergency operation device, wherein the hydraulic control valve assembly is located within the sealed chamber, and the emergency operation device is connected to the sealed chamber.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides an emergency operation device, including an operating component, an adapter plate, and a fixing plate located on the outside of a sealed chamber. The fixing plate is connected to the outer wall of the sealed chamber. The adapter plate has a threaded hole, and the operating component is screwed into the threaded hole, with its position relative to the fixing plate remaining unchanged. The emergency operation device also includes a guide rod and a trigger located on the inside of the sealed chamber. One end of the guide rod is connected to the adapter plate, and the guide rod passes through a through hole in the fixing plate and a through hole in the sealed chamber in sequence. The other end of the guide rod is engaged with the trigger. When the operating component is rotated, the adapter plate can drive the guide rod to move towards the inside of the sealed chamber, so that the trigger can move towards the emergency contact of the hydraulic control valve assembly until it presses against the emergency contact. That is, rotating the operating component on the outside of the sealed chamber can adjust the position of the adapter plate, making the adapter plate closer to or farther from the fixing plate, thereby adjusting the length of the guide rod extending into the sealed chamber, and thus adjusting the distance of the trigger relative to the sealed chamber. When the trigger needs to contact the manual emergency contact of the hydraulic control valve assembly within the sealed chamber, the operating component is rotated to bring the adapter plate closer to the fixed plate. This extends the portion of the guide rod into the sealed chamber, causing the trigger to move towards the manual emergency contact until it presses against it. The hydraulic control valve assembly then initiates its emergency action. Therefore, this emergency operating device simplifies the emergency operation procedures for the hydraulic control valve assembly and improves emergency operation efficiency.
[0021] This utility model also provides an underwater hydraulic system, including a sealed chamber, a hydraulic control valve assembly, and the aforementioned emergency operation device. The hydraulic control valve assembly is located inside the sealed chamber, and the emergency operation device is connected to the sealed chamber. This underwater hydraulic system simplifies the emergency operation procedures of the hydraulic control valve assembly and improves emergency operation efficiency. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] In underwater equipment, hydraulic power systems are the most commonly used solution due to their stable and reliable power, high load-bearing capacity, simple operation, and ease of automation. However, hydraulic power systems are difficult to troubleshoot once a failure occurs, usually requiring an emergency operation mode to control certain actions for emergency handling and prevent further losses. Current technologies often utilize external pipelines to provide power for certain actions in emergency situations. However, disassembling the hydraulic lines of some power components is very cumbersome, making it impractical in the complex underwater environment, and the cumbersome process significantly reduces the efficiency of emergency operations. Alternatively, when conditions permit, a second backup manual emergency hydraulic circuit can be installed, allowing certain actions to be performed manually. The disadvantages are that the system is more complex and requires highly skilled divers.
[0033] Therefore, this embodiment provides an emergency operation device 300, which can simplify the emergency operation steps of the hydraulic control valve group 200, reduce the requirements for divers' operation, and improve the efficiency of emergency operation.
[0034] like Figures 1-3 As shown, the emergency operation device 300 of this embodiment includes an operating component 1, an adapter plate 2, and a fixing plate 3 located on the outside of the sealed chamber 100. The fixing plate 3 is connected to the outer wall of the sealed chamber 100. The adapter plate 2 has a threaded hole, and the operating component 1 is screwed into the threaded hole, with the position of the operating component 1 relative to the fixing plate 3 remaining unchanged. The emergency operation device 300 also includes a guide rod 4 and a trigger 5 located on the inside of the sealed chamber 100. One end of the guide rod 4 is connected to the adapter plate 2, and the guide rod 4 passes through the through hole of the fixing plate 3 and the through hole of the sealed chamber 100 in sequence. The other end of the guide rod 4 is engaged with the trigger 5. When the operating component 1 rotates, the adapter plate 2 can drive the guide rod 4 to move toward the inside of the sealed chamber 100, so that the trigger 5 can move toward the emergency contact 201 of the hydraulic control valve group 200 until it presses against the emergency contact 201.
[0035] Rotating the operating component 1 outside the sealed chamber 100 adjusts the position of the adapter plate 2, moving it closer to or further away from the fixed plate 3. This adjusts the length of the guide rod 4 extending into the sealed chamber 100, thus adjusting the distance of the trigger 5 relative to the sealed chamber 100. When the trigger 5 needs to contact the manual emergency contact 201 of the hydraulic control valve assembly 200 within the sealed chamber 100, rotating the operating component 1 moves the adapter plate 2 closer to the fixed plate 3, extending the guide rod 4 further into the sealed chamber 100. The trigger 5 moves towards the manual emergency contact 201 until it presses against it, activating the emergency action of the hydraulic control valve assembly 200. Therefore, this emergency operation device 300 simplifies the emergency operation steps of the hydraulic control valve assembly 200 and improves emergency operation efficiency.
[0036] Optionally, to facilitate the rotation of the operating component 1, a hand-tightening end is provided on the operating component 1.
[0037] Optionally, a first limiting groove 31 is provided on the end face of the fixing plate 3 facing the operating member 1. One end of the operating member 1 is located in the first limiting groove 31. The first limiting groove 31 can limit the operating member 1 to a certain extent, and fixing the end of the operating member 1 can prevent the operating member 1 from tilting.
[0038] Optionally, the fixing plate 3 can be detachably connected to the outer wall of the sealed chamber 100. Optionally, in this embodiment, the fixing plate 3 is screwed to the outer wall of the sealed chamber 100 by bolts 10.
[0039] Optionally, the adapter plate 2 has a first through hole, and the emergency operating device 300 also includes a nut 6. One end of the guide rod 4 passes through the first through hole and is screwed to the nut 6. Optionally, a second limiting groove is provided at the opening of the first through hole facing the operating component 1. The nut 6 is located in the second limiting groove, which can prevent the nut 6 from being subjected to external force or even from disengaging from the guide rod 4 after rotation.
[0040] Optionally, the portion of the guide rod 4 located within the first through hole of the adapter plate 2 has a variable diameter section, and the first through hole also has a variable diameter section. Furthermore, the diameter of the cross-section of the portion of the guide rod 4 furthest from the nut 6 is larger than the diameter of the cross-section of the portion closer to the nut 6. By providing the variable diameter section, movement of the guide rod 4 relative to the adapter plate 2 along its own axial direction toward the nut 6 can be prevented. By providing the nut 6, movement of the guide rod 4 relative to the adapter plate 2 along its own axial direction toward the trigger element 5 can be prevented; that is, the position of the guide rod 4 relative to the adapter plate 2 along its own axial direction is fixed.
[0041] To prevent hydraulic oil leakage and contamination caused by a gap between the guide rod 4 and the through hole of the sealed chamber 100, the emergency operating device 300 may optionally include a sealing ring 7. The sealing ring 7 is sleeved on the guide rod 4 and sandwiched between the fixing plate 3 and the outer wall of the sealed chamber 100. Optionally, the sealing ring 7 is interference-fitted with the guide rod 4 to ensure that the gap between the guide rod 4 and the through hole of the sealed chamber 100 is sealed.
[0042] Alternatively, in other embodiments, a sealing element or the like may be provided in the through hole of the sealed chamber 100 to further improve the sealing effect.
[0043] Optionally, a third limiting groove is provided on the end face of the fixing plate 3 facing the sealing chamber 100, and the sealing ring 7 is located in the third limiting groove. Optionally, the sealing ring 7 is interference-fitted with the bottom of the third limiting groove, that is, the bottom of the third limiting groove and the outer wall of the sealing chamber 100 jointly press against the sealing ring 7, which can further ensure the effective sealing performance of the sealing ring 7.
[0044] Optionally, the trigger member 5 has a second through hole, and the inner wall of the second through hole has a stepped surface 51. The stepped surface 51 is disposed away from the operating member 1, that is, the stepped surface 51 is disposed towards the hydraulic control valve assembly 200. The guide rod 4 passes through the second through hole, and the other end of the guide rod 4 abuts against the stepped surface 51.
[0045] Optionally, the emergency operation device 300 also includes an elastic element 8, which is sleeved on the guide rod 4. The elastic element 8 has a tendency to press its end against the step surface 51 to ensure that the end of the guide rod 4 will not detach from the step surface 51. When there is no other external force, the two are always pressed tightly together.
[0046] Optionally, the emergency operation device 300 further includes an auxiliary plate 9, located between the trigger 5 and the inner wall of the sealed chamber 100. The auxiliary plate 9 has a third through hole, and a fourth limiting groove is formed at the opening of the third through hole facing the trigger 5. The guide rod 4 passes through the third through hole, and the elastic element 8 is partially located within the fourth limiting groove to prevent the elastic element 8 from tilting. Optionally, the elastic element 8 is a spring, with one end pressing against the bottom of the fourth limiting groove and the other end pressing against the trigger 5. The auxiliary plate 9 prevents the elastic element 8 from directly pressing against the inner wall of the sealed chamber 100; instead, the auxiliary plate 9 presses against the inner wall of the sealed chamber 100 under the elastic force of the elastic element 8.
[0047] It is known that under the elastic force of the elastic member 8, the trigger member 5 tends to move away from the wall of the sealed chamber 100, that is, it tends to move towards the hydraulic control valve group 200. The trigger member 5 will drive the guide rod 4 to tend to extend further into the sealed chamber 100. The guide rod 4 drives the adapter plate 2 and the operating member 1, so that the end of the operating member 1 presses against the first limiting groove 31 and will not detach.
[0048] Optionally, in this embodiment, the trigger 5 includes a trigger plate and a plurality of contacts 52. The plurality of contacts 52 are mounted on the trigger plate, and the plurality of contacts 52 correspond to a plurality of emergency contacts 201 on the hydraulic control valve group 200. The second through hole is opened in the trigger plate.
[0049] Optionally, in this embodiment, in order to ensure the stability of the extension and retraction position of the contact 52 and prevent the trigger plate from tilting, multiple contacts 52 are arranged sequentially at intervals along the first direction, and two guide rods 4 are arranged at intervals along the first direction. Correspondingly, two through holes and slots are also provided on each component, and two nuts 6, sealing rings 7, and elastic elements 8 are all provided.
[0050] This embodiment also provides an underwater hydraulic system, including a sealed chamber 100, a hydraulic control valve group 200, and the aforementioned emergency operation device 300. The hydraulic control valve group 200 is located inside the sealed chamber 100, that is, inside the accommodating cavity 101 of the sealed chamber 100. The emergency operation device 300 is connected to the sealed chamber 100, and the contacts 52 of the multiple triggers 5 correspond to the multiple emergency contacts of the hydraulic control valve.
[0051] Disassembly of hydraulic lines for power components in existing technologies is extremely cumbersome and not feasible in complex underwater environments. Furthermore, disassembly and reassembly of hydraulic power lines can lead to hydraulic oil leaks and environmental pollution. This embodiment's underwater hydraulic system includes an emergency operation device 300. Divers or ROVs can pressurize the emergency contact 201 of the hydraulic control valve assembly 200 by rotating the operating component 1, enabling emergency operation of the underwater hydraulic system. This underwater hydraulic system eliminates the need to disassemble the hydraulic lines for power components, simplifying the emergency operation steps of the hydraulic control valve assembly 200, improving emergency operation efficiency, preventing hydraulic oil leaks, protecting the environment, and offering good safety and operability.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
