Abstract
Description
Technical Field
[0001] This invention relates to the field of high-pressure chamber technology, and more specifically, to a node transition chamber device for the rapid construction of a high-pressure chamber cluster. Background Technology
[0002] Currently, rescue vessels are rapidly developing towards larger and more specialized sizes, and the demand for modular and mobile rescue equipment is becoming increasingly prominent. To meet the need for rapid treatment of large numbers of people in distress during complex underwater rescue missions, it is necessary to have the capability to quickly and mobilely deploy large high-pressure manned cabin clusters to provide an efficient and safe decompression treatment environment.
[0003] However, there are still significant bottlenecks in the rapid docking and integration of the cabin group: (1) The high-pressure compartment and the base rely on the corner fittings of the container for positioning and fixing. The inherent tolerance of these fittings (usually more than ±10mm) is difficult to meet the accuracy requirements of the high-pressure compartment sealing and docking (which need to be controlled within ±2mm). This positioning error can easily lead to misalignment of compartment connections, sealing failure, and even threaten personnel safety, seriously restricting rescue efficiency; (2) Research on high-pressure chamber docking is mostly focused on fixed medical chambers or small mobile units. There is still a gap in the rapid docking technology for shipborne mobile large chamber groups. Traditional solutions such as manual adjustment and hydraulic fine-tuning mechanisms have defects such as long time consumption, reliance on operating experience, and poor adaptability, which are difficult to meet the timeliness requirements of maritime emergency rescue.
[0004] In conclusion, the current high-pressure chamber docking method still has shortcomings and needs to be improved. Summary of the Invention
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
[0006] Therefore, the object of the present invention is to provide a node transition chamber device for rapid construction of a hyperbaric chamber cluster, comprising a hyperbaric chamber and a treatment chamber, and a floating connection mechanism for connecting the hyperbaric chamber and the treatment chamber. The hyperbaric chamber is mounted within a modular frame via multiple supports. The modular frame has corner fittings at its edges. The hyperbaric chamber has three horizontal docking channels and one emergency channel around its perimeter. The treatment chamber has one docking channel. The floating connection mechanism includes a spherical float channel that movably docks with the docking channel, a clamping ring for pressing the spherical float channel, and a locking mechanism for docking two spherical float channels. A sealing assembly is provided on the outer wall of the spherical float head channel, and an outer spherical surface is formed on the outer wall of the spherical float head channel.
[0007] The locking mechanism includes two clamps and a push assembly for driving the clamps to rotate.
[0008] As a preferred technical solution: As described above, a node transition chamber device for rapid construction of a high-pressure chamber group has an integrally formed docking interface at one end of the docking channel, an annular limiting step is formed between the docking interface and the docking channel, the inner wall of the docking interface has a first concave spherical surface adapted to the outer spherical surface, and the end face of the docking interface has multiple threaded holes.
[0009] The clamping ring is sleeved on the spherical floating head channel. The inner wall of the clamping ring forms a second concave spherical surface that matches the outer spherical surface. The clamping ring has multiple fixing holes that match the threaded holes.
[0010] Through the above technical solution, the first concave spherical surface and the second concave spherical surface cooperate with each other, and the outer spherical surface can form a surface contact support for the spherical floating head channel. Furthermore, the center of the first concave spherical surface and the center of the second concave spherical surface coincide with the center of the outer spherical surface, ensuring that the spherical floating head channel can freely deflect and swing.
[0011] As described above, in a node transition chamber device for rapid assembly of a high-pressure chamber group, the inner diameters of the first and second concave spherical surfaces are consistent with the outer diameter of the outer spherical surface, and the inner diameter of the end of the clamping ring away from the docking channel is smaller than the maximum outer diameter of the outer spherical surface.
[0012] Through the above technical solution, the size design of the first concave spherical surface and the second concave spherical surface can wrap around the spherical floating head channel, thereby forming a complete ball joint with the outer spherical surface, and thus realizing the deflection and swing of the spherical floating head channel.
[0013] As described above, in a node transition chamber device for rapid assembly of a high-pressure chamber group, the spherical floating head channel facing the docking channel is parallel to the limiting step, and there is a gap between the limiting step and the end face of the spherical floating head channel.
[0014] Through the above technical solution, the setting of the limiting step can limit the deflection range of the spherical float channel, ensuring that the spherical float channel can only deflect and swing freely within a certain range.
[0015] As described above, a node transition chamber device for rapid construction of a high-pressure chamber group includes a sealing assembly comprising an inflatable sealing ring and an inflation pipeline connected to the inflatable sealing ring. The inflatable sealing ring is fixedly bonded to the outer wall of the spherical floating head channel that fits against the first concave spherical surface. A through hole for the inflation nozzle of the inflation pipeline is provided on the outer wall of the spherical floating head channel at the end away from the docking channel.
[0016] With the above technical solution, the inflation nozzle of the inflation pipeline is located far from the outer spherical surface and will not be blocked by the interface and the clamping ring, thus facilitating the inflation of the inflatable sealing ring through the inflation pipeline.
[0017] As described above, a node transition chamber device for rapid construction of a high-pressure chamber group has a retaining ring integrally formed at the end of the spherical floating head channel away from the docking channel, and a retaining groove adapted to the retaining ring is opened on the inner circular surface of the retaining ring.
[0018] With the above technical solution, after the two clamps are closed, the clamping rings on the two spherical float channels can be tightly held and fitted through the clamping groove, thereby achieving the docking and fitting of the two spherical float channels.
[0019] As described above, a node transition chamber device for rapid assembly of a hyperbaric chamber cluster includes a propulsion assembly comprising a lead screw and a rotating handwheel bolted to the top of the lead screw. The lead screw bearing is mounted on a set of supports, which are bolted to the module frame. A fixing block threadedly connected to the lead screw is fitted onto the lead screw, and the threads of the two fixing blocks engaging with the lead screw rotate in opposite directions. The fixed block is welded to both ends with transmission columns, and a set of guide rods runs through the fixed block, with both ends of the guide rods fixed to the support.
[0020] With the above technical solution, the lead screw is designed with double threads, one end is a left-hand thread and the other end is a right-hand thread. The two threads have the same pitch. When the lead screw rotates, the threads at both ends will drive the fixed blocks that are engaged with it to move. The two fixed blocks will move closer to each other or further away from each other.
[0021] As described above, a node transition chamber device for rapid construction of a high-pressure chamber group includes a clamp with a semi-circular structure. Two clamps are movably connected by a hinge seat, which is welded and fixed to the outer wall of the spherical floating head channel. Two parallel transmission bars are welded to the outer wall of the clamp.
[0022] Through the above technical solution, the two clamps can rotate through the hinge seat, thereby tightening and loosening the spherical floating head channel.
[0023] As described above, a node transition chamber device for rapid construction of a high-pressure chamber group has a U-shaped notch for inserting a transmission column in the transmission bar. The fixing block is located between two transmission bars, and the notch is connected to one side of the transmission bar. Both the notch and the transmission column are horizontally arranged.
[0024] With the above technical solution, the transmission column and the notch can slide relative to each other. When the transmission column moves vertically, it slides in the notch and drives the transmission bar to deflect, which in turn drives the clamp to rotate. Beneficial effects
[0025] This invention features a spherical floating head channel, abandoning the traditional welding or flange rigid connection method. It adopts a floating head docking channel, and the channel and the high-pressure chamber form a movable connection through a spherical contact surface. This allows the channel to freely deflect and swing within a certain range (±5°~±10°) to compensate for the positioning deviation of the container corner fittings. This effectively overcomes problems such as shipboard deck vibration, deformation, and inaccurate positioning of container corner fittings, ensuring reliable docking under complex sea conditions.
[0026] (2) The outer spherical surface of the spherical floating head channel of the present invention is provided with an inflatable sealing ring. Before docking, low-pressure gas is pre-filled to form an initial seal. After docking, the pressure is increased to the working pressure to ensure the reliability of dynamic sealing under high pressure environment.
[0027] (3) The present invention is equipped with a clamp. When the two compartments dock, the spherical floating head channel still has a slight positional deviation after initial contact. The clamp is applied with a uniform clamping force by hydraulic or electric drive, which forces the floating head channels on both sides to deflect adaptively until the sealing surfaces are completely in contact, and finally achieves high-precision (within ±1mm) sealing docking.
[0028] (4) The present invention uses corner fittings for docking, is compatible with existing container corner fitting base standards, does not require modification of the deck structure, supports rapid assembly of multiple compartments, and meets the development needs of motorization and modularization of rescue equipment.
[0029] (5) The high-pressure air chamber of the present invention is provided with multiple docking channels. The high-pressure air chamber, as the core connection unit, can dock with different numbers of treatment chambers through the docking channels, thereby forming an expandable high-pressure treatment chamber group node hub.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0034] like Figures 1-7 As shown in the figure, this invention discloses a node transition chamber device for rapid construction of a hyperbaric chamber cluster, including a hyperbaric air chamber 1 and a treatment chamber 28, as well as a floating connection mechanism for connecting the hyperbaric air chamber 1 and the treatment chamber 28. The hyperbaric chamber 1 is mounted within the modular frame 2 via multiple supports. The corners of the modular frame 2 are fitted with corner fittings 24. Three docking channels 3 and one emergency channel 4 are horizontally arranged around the hyperbaric chamber 1. The treatment chamber 28 is equipped with one docking channel 3. The floating connection mechanism includes a spherical float channel 10 that is movably docked with the docking channel 3, a clamping ring 6 for pressing the spherical float channel 10, and a locking mechanism for docking two spherical float channels 10. A sealing component is provided on the outer wall of the spherical floating head channel 10, and an outer spherical surface 29 is formed on the outer wall of the spherical floating head channel 10.
[0035] The locking mechanism includes two clamps 22 and a push assembly for driving the clamps 22 to rotate.
[0036] Specifically, during implementation, the high-pressure air chamber 1 is positioned by the mating corner piece 24 on the module frame 2. Then, the clamping ring 6 is pre-fitted onto the spherical floating head channel 10. Next, the clamping ring 6 is attached to the mating interface 5 so that the fixing hole 13 and the threaded hole 14 are aligned one by one. The end of the screw is passed through the fixing hole 13 and screwed into the threaded hole 14. A nut is screwed into the head end of the screw, thus completing the fixation of the clamping ring 6 and the mating interface 5.
[0037] The clamping ring 6 can press the spherical floating head channel 10 onto the docking channel 3. At this time, the outer spherical surface 29 of the spherical floating head channel 10 fits against the first concave spherical surface 8 and the second concave spherical surface 9. In this way, the spherical floating head channel 10 forms a movable connection with the docking channel 3 through the spherical contact surface. The spherical floating head channel 10 can freely deflect and swing within a certain range (±5°~±10°) to compensate for the positioning deviation of the docking corner piece 24 (±10mm or more).
[0038] When the high-pressure air chamber 1 and the treatment chamber 28 are docked, the spherical floating head channels 10 on the high-pressure air chamber 1 and the treatment chamber 28 still have slight positional deviations after initial contact. By manually or hydraulically driving the two clamps 22 to rotate and applying a uniform clamping force, the two spherical floating head channels 10 are forced to adaptively deflect until they are completely fitted, and finally a high-precision (±10mm) sealed docking is achieved.
[0039] After docking, the sealing components can ensure the reliability of dynamic sealing under high pressure.
[0040] When it is necessary to build a fleet, the high-pressure air chamber 1 can be used as the core connecting unit, as follows: Docking 1 treatment cabin 28: It can be connected to any one of the 3 docking channels 3 to adapt to different deck space constraints.
[0041] Two treatment chambers can be docked: any two of the three docking channels can be selected for connection. The overall layout adopts a straight line arrangement or an L-shaped right angle arrangement to optimize space utilization.
[0042] The system connects three treatment chambers 28: all three docking channels are connected, and the overall layout adopts a "T" shape to maximize the capacity of the treatment chambers 28 while maintaining structural stability.
[0043] Emergency Channel 4 allows for rapid decompression evacuation or pressurized entry for medical personnel in emergency situations, ensuring the safety and flexibility of the rescue process.
[0044] The hyperbaric air chamber 1 and the treatment chamber 28 adopt standardized interfaces and rapid docking technology to ensure that the docking time of a single interface is controlled within 30 minutes, thus ensuring that the chamber group can be rapidly assembled.
[0045] The multi-interface design enables strong modular scalability, supports rapid assembly of multiple modules, and allows for the flexible construction of large-scale hyperbaric therapy chamber clusters to meet the decompression and treatment needs of large numbers of people in distress.
[0046] In one specific embodiment of the present invention, a mating interface 5 is integrally formed at one end of the docking channel 3, an annular limiting step 7 is formed between the mating interface 5 and the docking channel 3, a first concave spherical surface 8 adapted to the outer spherical surface 29 is formed on the inner wall of the mating interface 5, and a plurality of threaded holes 14 are provided on the end face of the mating interface 5.
[0047] The clamping ring 6 is sleeved on the spherical floating head channel 10. The inner wall of the clamping ring 6 forms a second concave spherical surface 9 that matches the outer spherical surface 29. The clamping ring 6 has a plurality of fixing holes 13 that match the threaded holes 14.
[0048] The inner diameters of the first concave spherical surface 8 and the second concave spherical surface 9 are the same as the outer diameter of the outer spherical surface 29, and the inner diameter of the end of the clamping ring 6 away from the docking channel 3 is smaller than the maximum outer diameter of the outer spherical surface 29.
[0049] Specifically, such as Figures 1-3 As shown, after the spherical floating head channel 10 is installed, the spherical floating head channel 10 can deflect and swing within the interface 5 and the clamping ring 6, thereby breaking through the limitations of traditional rigid connection, dynamically compensating for translation and deflection positioning errors, and adapting to shipboard deck vibration and deformation conditions.
[0050] The inner diameter design of one end of the clamping ring 6 can prevent the spherical floating head channel 10 from coming off to the side of the clamping ring 6, thereby improving the reliability after the hull is connected.
[0051] In one specific embodiment of the present invention, the spherical floating head channel 10 is parallel to the side facing the docking channel 3 and the limiting step 7, and there is a gap between the limiting step 7 and the end face of the spherical floating head channel 10.
[0052] Specifically, such as Figure 4 and Figure 6 As shown, when the spherical floating head channel 10 deflects and swings, one end of the spherical floating head channel 10 will touch the limiting step 7, thereby limiting the deflection angle range of the spherical floating head channel 10, so that the spherical floating head channel 10 can deflect and swing freely within a certain range.
[0053] In one specific embodiment of the present invention, the sealing assembly includes an inflatable sealing ring 11 and an inflation pipe 12 connected to the inflatable sealing ring 11. The inflatable sealing ring 11 is fixedly bonded to the outer wall of the spherical floating head channel 10 that fits against the first concave spherical surface 8. A through hole for the inflation nozzle of the inflation pipe 12 to pass through is provided on the outer wall of the spherical floating head channel 10 away from the docking channel 3.
[0054] Specifically, such as Figure 4 and Figure 6 As shown, after the spherical floating head channel 10 is connected to the docking channel 3, low-pressure gas is injected into the inflatable sealing ring 11 through the inflation pipeline 12 to form an initial seal. After the two spherical floating head channels 10 are tightly connected by the clamp 22, gas is injected into the inflatable sealing ring 11 through the inflation pipeline 12 and pressurized to the working pressure to ensure the reliability of dynamic sealing under high pressure.
[0055] In one specific embodiment of the present invention, a retaining ring 26 is integrally formed at the end of the spherical floating head channel 10 away from the docking channel 3, and a retaining groove 25 adapted to the retaining ring 26 is provided on the inner circular surface of the clamp 22.
[0056] Specifically, such as Figure 3 , Figure 4 and Figure 7 As shown, the groove walls on both sides of the slot 25 are inclined, and a sealing ring is bonded to one end face of the retaining ring 26, while the other end face is inclined. The inclined surfaces on the slot 25 and the retaining ring 26 cooperate with each other, so that as the two clamps 22 gradually close, the squeezing force generated by the inclined surfaces forces the two spherical floating head channels 10 to adaptively deflect until they are completely fitted, ultimately achieving high-precision sealing docking.
[0057] After the spherical floating head channels 10 on the high-pressure air chamber 1 and the treatment chamber 28 are connected, a sealing fit is achieved through the sealing ring. In conjunction with the inflatable sealing ring 11, a double sealing design is achieved, which not only enables the rapid establishment of low-pressure pre-sealing, but also maintains long-term sealing performance in high-pressure environments above 1MPa, with no risk of leakage and high safety.
[0058] In one specific embodiment of the present invention, the pushing assembly includes a lead screw 16 and a rotating handwheel 15 bolted to the top of the lead screw 16. The lead screw 16 is bearing a set of supports 17, which are bolted to the module frame 2. A fixing block 18 is sleeved on the lead screw 16 and threadedly connected to it. The threads of the two fixing blocks 18 that engage with the lead screw 16 have opposite directions of rotation. The fixed block 18 is welded to both ends with transmission columns 19, and a set of guide rods 27 runs through the fixed block 18. The two ends of the guide rods 27 are fixed to the support 17.
[0059] Specifically, such as Figure 2 and Figure 5 As shown, the lead screw 16 can be kept in a fixed state by a set of supports 17, and the lead screw 16 can be driven to rotate axially on the supports 17 by rotating the handwheel 15.
[0060] A set of guide rods 27 are set, and the guide rods 27 are vertical in shape, so as to ensure that the fixed blocks 18 can move vertically. When the lead screw 16 rotates, the two fixed blocks 18 can be driven to move vertically through the two threads. The two fixed blocks 18 can move closer to each other or further away from each other.
[0061] In one specific embodiment of the present invention, the clamp 22 has a semi-circular structure, and the two clamps 22 are movably connected by a hinge seat 23. The hinge seat 23 is welded and fixed to the outer wall of the spherical floating head channel 10, and two parallel transmission bars 20 are welded to the outer wall of the clamp 22.
[0062] The transmission bar 20 has a U-shaped notch 21 for inserting the transmission post 19. The fixing block 18 is located between the two transmission bars 20. The notch 21 is connected to one side of the transmission bar 20. Both the notch 21 and the transmission post 19 are horizontally arranged.
[0063] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, since the clamp 22 is fixed to the spherical floating head channel 10 through the hinge seat 23, before the spherical floating head channel 10 docks with the docking channel 3, the notch 21 and the transmission column 19 are kept on the same horizontal plane. Then, the spherical floating head channel 10 is moved horizontally so that the notch 21 on the transmission bar 20 can be fitted onto the transmission column 19, and the fixing block 18 is positioned between the two transmission bars 20.
[0064] Next, the spherical floating head channel 10 is pushed to complete the docking with the docking channel 3. After docking, the spherical floating head channel 10 will freely deflect and swing within a certain range to compensate for the positioning deviation of the container corner fittings. At this time, the transmission bar 20 rotates synchronously. Through the setting of the notch 21, the deflection of the transmission bar 20 will not be blocked by the transmission column 19.
[0065] When it is necessary to dock the spherical floating head channels 10 on the high-pressure air chamber 1 and the treatment chamber 28, the two fixed blocks 18 are driven away from each other by the drive screw 16. The fixed blocks 18 drive the transmission column 19 on them to move synchronously. The transmission column 19 slides in the notch 21 and drives the transmission bar 20 to deflect. The transmission bar 20 drives the clamp 22 to rotate around the hinge seat 23, so that the two clamps 22 are in the maximum open state, which facilitates the contact of the two spherical floating head channels 10.
[0066] After the two spherical float channels 10 are fitted together, the drive screw 16 drives the two fixed blocks 18 to move closer to each other. The transmission column 19 slides in the notch 21 and pushes the transmission bar 20 to reset. The transmission bar 20 drives the clamp 22 to rotate around the hinge seat 23. In this way, the two clamps 22 close together and, under the action of the groove 25 and the ring 26, complete the sealing and fitting of the spherical float channels 10.
