Abstract
Description
Technical Field
[0001] This application relates to the technical field of high-pressure chamber connection mechanisms, and in particular to a floating connection device for rapid docking of high-pressure chambers. Background Technology
[0002] With the deepening of my country's modernization, rescue ships are rapidly developing towards larger and more specialized models, highlighting the increasing demand for modular and mobile rescue equipment. To meet the need for rapid treatment of large numbers of people in distress during complex underwater rescue missions, there is an urgent need for the ability to quickly and mobilely deploy large high-pressure manned cabin clusters to provide an efficient and safe decompression treatment environment. However, the core of deploying such clusters lies in the rapid docking and integration of high-pressure cabin modules, and existing technologies face significant bottlenecks: although the deck equipment base has achieved standardized design, and the high-pressure cabin and base rely on container corner fittings for positioning and fixation, the accuracy of the high-pressure cabin sealing docking needs to be controlled within ±2 mm. The inherent tolerance of the positioning and fixation between the high-pressure cabin and the base is usually ±10 mm or more, making it difficult to meet the accuracy requirements of the high-pressure cabin sealing docking. This positioning error can easily lead to misalignment of cabin sections, sealing failure, and even threaten personnel safety, severely restricting rescue efficiency.
[0003] Currently, research on high-pressure compartment docking, both domestically and internationally, largely focuses on fixed medical compartments or small, mobile units. Rapid docking technology for large, mobile shipboard compartments remains a gap. Traditional solutions for addressing positioning errors, such as manual adjustment and hydraulic fine-tuning mechanisms, suffer from drawbacks such as long processing times, reliance on operational experience, and poor adaptability, making them unsuitable for meeting the timeliness requirements of maritime emergency rescue. Therefore, this application proposes a floating connection device for rapid docking of high-pressure compartments. Summary of the Invention
[0004] In order to achieve rapid docking of large shipboard motorized modules, this application provides a floating connection device for rapid docking of high-pressure modules.
[0005] The floating connection device for rapid docking of hyperbaric chambers provided in this application adopts the following technical solution: A floating connection device for rapid docking of a hyperbaric chamber includes: Connectors are used to secure the device to the hyperbaric chamber; A floating channel is connected to a connector. The floating channel communicates with the high-pressure chamber. A portion of the floating channel is inserted into the hatch of the high-pressure chamber, and the connection surface between the floating channel, the hatch of the high-pressure chamber, and the connector is a spherical contact surface.
[0006] Furthermore, a seal is provided on the spherical contact surface.
[0007] Furthermore, the sealing element is an inflatable sealing ring.
[0008] Furthermore, there are two of each of the connectors and floating channels, with each connector and floating channel corresponding to the other. The floating channel is connected to the corresponding connector, and the two floating channels are connected by a locking device.
[0009] Furthermore, the locking element includes: At least two locking plates are provided, and adjacent locking plates are rotatably connected. The free ends of the two locking plates at the ends can move in a direction that approaches or moves away from each other. The locking plates are provided with slots for engaging with the two floating channels.
[0010] Furthermore, the locking plate consists of two pieces, with one end of the two locking plates rotatably connected and the other end capable of moving towards or away from each other.
[0011] Furthermore, the locking component also includes a locking frame for fixed connection with the high-pressure chamber, and the two locking plates are rotatably connected by a rotating shaft, which is fixedly connected to the locking frame.
[0012] Furthermore, a movable screw is rotatably connected to the base connected to the high-pressure chamber, and a movable push block is threadedly connected to the movable screw. There are two movable push blocks, and the threads of the two movable push blocks are opposite. The two movable push blocks are correspondingly arranged with two locking plates, and the movable push blocks are connected to the corresponding locking plates.
[0013] In summary, the beneficial technical effects of this application are as follows: 1. The floating passageway, connecting components, and high-pressure chamber are connected by a spherical contact surface, allowing the floating passageway to freely deflect and swing within a certain range to compensate for the positioning deviation of the container corner fittings. This overcomes the shortcomings of traditional solutions, such as long processing time, reliance on operational experience, and poor adaptability, achieving rapid docking of large mobile compartments on ships to meet the timeliness requirements of maritime emergency rescue. In addition, the use of the spherical contact surface of the floating passageway to replace the traditional rigid connection breaks the limitations of the traditional rigid connection and can dynamically compensate for translation and deflection positioning errors, adapting to shipboard deck vibration and deformation conditions. 2. An inflatable sealing ring is set on the spherical contact surface. Before docking with the high-pressure chamber, low-pressure gas is pre-filled to form an initial seal. After docking with the high-pressure chamber, the pressure is increased to the working pressure, thereby improving the reliability of dynamic sealing under high-pressure environment. 3. The combination of the inflatable sealing ring and the locking plate not only enables the rapid deployment of low-pressure pre-sealing, but also ensures long-term sealing stability under high pressure through mechanical locking. The floating connection device of this application improves efficiency by more than 50% compared with the traditional flange docking. Attached Figure Description

Figure 1 and Figure 2 It includes a connector 1, a floating channel 2, a seal 3, and a locking element 4. In this embodiment, there are two connectors 1, two floating channels 2, and two seals 3, and each connector 1, floating channel 2, and seal 3 are provided in a one-to-one correspondence. In this embodiment, the connector 1 is a connecting ring, which is sleeved on the outside of the floating channel 2. The connecting ring is connected to the hatch end of the high-pressure chamber 6 by multiple bolts, and the bolts pass through the connecting ring and are threadedly connected to the hatch end of the high-pressure chamber 6. In this embodiment, there are six bolts, and the six bolts are evenly distributed along the circumference of the connecting ring. In other embodiments, the connector 1 can be a connecting block, and at least two connecting blocks are provided, and the connecting blocks are evenly distributed along the circumference of the hatch of the high-pressure chamber 6. Each connecting block is threadedly connected to the hatch end wall of the high-pressure chamber 6 by bolts.
[0018] The floating channel 2 is used to communicate with the high-pressure chamber 6, and part of the floating channel 2 extends beyond the corresponding connecting ring and inserts into the hatch of the high-pressure chamber 6. The connection surface between the floating channel 2 and the inner wall of the hatch of the high-pressure chamber 6, and the connecting piece 1, is a spherical contact surface 21, and the center of the spherical contact surface 21 is located on the side of the connecting ring closer to the high-pressure chamber 6, so that the connecting ring can tightly connect the floating channel 2 and the high-pressure chamber 6. At the same time, the spherical contact surface of the floating channel 2 allows the floating channel 2 to swing at a certain angle. The ends of the two floating channels 2 that are away from the corresponding connecting pieces 1 are connected by locking pieces 4.
[0019] Reference Figure 1 and Figure 3 The locking component 4 includes a locking plate 41 and a locking frame 42. The locking frame 42 is annular and is sleeved on the outer peripheral wall of the floating channel 2. Multiple bolts are provided on the locking frame 42, with the bolt shanks passing through the locking frame 42 and threadedly connected to the outer peripheral wall of the floating channel 2. The bolt heads abut against the outer peripheral side of the locking frame 42. In this embodiment, two locking plates 41 are provided, both being arc-shaped. A rotating shaft 421 is fixedly connected to the locking frame 42. One end of each locking plate 41 is rotatably connected to the rotating shaft 421, and the other end is fixedly connected to a connecting plate 412. The connecting plates 412 on the two locking plates 41 can move towards or away from each other to form a clamp structure.
[0020] Reference Figure 1 , Figure 3 and Figure 4 Two connecting plates 412 are provided on the locking plate 41. The two connecting plates 412 are arranged sequentially along the axial direction of the locking plate 41 and are parallel and spaced apart. One end of each connecting plate 412 is fixedly connected to the free end of the corresponding locking plate 41, and the other end extends in a direction away from the floating channel 2. Each connecting plate 412 has a connecting groove 413, both ends of which are open, and the opening of the connecting groove 413 faces away from the floating channel 2. A moving assembly 5 for adjusting the movement of the two connecting plates 412 is provided on the base of the high-pressure chamber 6.
[0021] The movable assembly 5 includes a movable screw 51 and a movable push block 52. The movable screw 51 is rotatably connected to the base of the high-pressure chamber 6 around its own axis, and one end of the movable screw 51 is fixedly connected to a handwheel 511. Two movable push blocks 52 are provided, each corresponding to one of the two locking plates 41, and each movable push block 52 is connected to the two connecting plates 412 of the corresponding locking plate 41. The movable push block 52 includes a movable sub-block 521 and a movable shaft 522. The movable sub-block 521 is located between the two connecting plates 412 of the corresponding locking plate 41, and the movable sub-block 521 is threadedly connected to the movable screw 51. The threads on the movable sub-blocks 521 of the two movable push blocks 52 are opposite, so that when the movable screw 51 rotates, the two movable push blocks 52 can move towards or away from each other. There are two movable shafts 522, which are respectively located on both sides of the movable sub-block 521, and each movable shaft 522 is inserted into the connecting groove 413 of the corresponding side connecting plate 412.

The ends of the floating channels 2 engage with the mounting grooves 22. The side of the mounting groove 22 opposite to the corresponding connector 1 abuts against the sidewall of the slot 411, and the contact surfaces of the mounting groove 22 and the slot 411 are inclined. To improve the sealing of the connection between the two floating channels 2, a sealing ring 23 is embedded in the end of the floating channel 2 opposite to the corresponding connector 1.
[0023] The seal 3 is located on the spherical contact surface 21, and the seal 3 adopts an inflatable sealing ring, which allows the operator to pre-fill with low-pressure gas to form an initial seal before docking, and pressurize to the working pressure after docking to improve the dynamic sealing reliability of the floating connection device under high pressure environment.
[0024] In other embodiments, a connecting ring, a floating channel 2, and a sealing element 3 are each provided, and the end of the floating channel 2 facing away from the high-pressure chamber 6 is fixedly connected to the hatch end of another high-pressure chamber 6 by bolts.
[0025] The implementation principle of a floating connection device for rapid docking of a high-pressure chamber 6 according to an embodiment of this application is as follows: the operator fixes the connector 1 of the floating connection device to the hatch side wall of the high-pressure chamber 6, and then fixes the two floating channels 2 with locking parts 4, thereby completing the rapid docking of the high-pressure chamber 6.
