Description

Technical Field

[0001] This invention relates to the field of underwater emergency escape training equipment technology, and in particular to an underwater escape fully immersive cabin for emergency rescue. Background Technology

[0002] The underwater escape immersion chamber is mainly used to simulate accident conditions such as submersion, tilting, and overturning of helicopters, vehicles, or other transport equipment after they fall into the water. During training, the chamber is lowered into the water and rotated to a preset angle. Trainees then complete underwater unlocking, orientation, and escape training through the escape window to improve their emergency escape capabilities in the event of an underwater accident.

[0003] Existing underwater escape capsules typically consist of a hull, a tilting support structure, and a drive mechanism. The drive mechanism rotates the hull via gears, chains, or other transmission components. Due to the large overall size and weight of the hull, and the need for repeated submersion, tilting, and repositioning during training, the transmission components are subjected to alternating loads over extended periods. When using a conventional geared ring drive, high precision is required in the machining and assembly of the geared ring. Localized deformation of the hull frame or transmission components can easily cause changes in the meshing clearance, affecting the continuity and stability of the hull's tilting.

[0004] Meanwhile, the underwater training environment places high demands on the sealing and safety of the drive system. When using an electric drive system, the motor, cables, and electrical connections need to be waterproofed and sealed, making the equipment structure and maintenance process more complex. When multiple drive systems are used to synchronously rotate the hull, the synchronicity of the operation of each drive system also needs to be controlled, which increases the control difficulty.

[0005] Therefore, an emergency rescue underwater escape fully immersion cabin is proposed. Summary of the Invention

[0006] In view of this, the present invention provides an underwater escape fully immersive cabin for emergency rescue, in order to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the present invention is implemented as follows: an emergency rescue underwater escape fully immersive cabin, including a cabin assembly, a cabin rotating ring, a fixed support ring and a tilting drive mechanism;

[0008] The cabin assembly includes a cabin frame, four window frames, four escape windows, and a cabin roof skin. Two of the window frames are fixedly connected to each side of the cabin frame, and each window frame is detachably connected to one of the escape windows. The cabin roof skin is fixedly connected to the top of the cabin frame.

[0009] The cabin rotating ring is fixedly connected to the front end of the cabin frame, the fixed support ring is coaxially sleeved on the outside of the cabin rotating ring, and an annular pin group is fixedly connected to the inner circumference of the cabin rotating ring. The annular pin group includes multiple pins arranged at intervals along the circumference of the cabin rotating ring.

[0010] The flipping drive mechanism includes a lifting ring, a drive housing, a rotary encoder, a pneumatic motor, a transmission gear, a pin drive wheel, and a guide wheel assembly. The two ends of the lifting ring are respectively hinged to the top of the drive housing via hinge shafts. The bottom of the drive housing is fixedly connected to the guide wheel assembly via bolts. An clearance groove is provided at the connection between the drive housing and the guide wheel assembly.

[0011] The pneumatic motor is fixedly installed in the drive housing. The transmission gear is fixed to the output shaft of the pneumatic motor via a key connection. The rotary encoder is fixed to the outside of the drive housing by screws. The output shaft of the pneumatic motor passes through the drive housing and is coaxially connected to the detection shaft of the rotary encoder via a coupling.

[0012] The pin drive wheel is rotatably mounted in the drive housing via a rotating shaft. The pin drive wheel meshes with the transmission gear and the annular pin assembly, and a portion of the pin drive wheel passes through the clearance groove. The guide wheel assembly is fixed to the fixed support ring by bolts and rolls with the hull rotating ring.

[0013] Furthermore, the cabin frame includes longitudinal beams, transverse beams, arc-shaped top beams, and diagonal bracing beams. The two ends of the transverse beams are respectively welded to the longitudinal beams located on both sides of the cabin frame. The two ends of the arc-shaped top beams are respectively welded to the corresponding longitudinal beams. The diagonal bracing beams are welded between the longitudinal beams and the transverse beams.

[0014] Furthermore, the four window frames are respectively welded to both sides of the cabin frame, and the two window frames on the same side are arranged at intervals along the length of the cabin frame.

[0015] Furthermore, the roof skin is in the shape of an arc-shaped plate and is fixed to the outside of the plurality of arc-shaped roof beams by screws.

[0016] Furthermore, the cabin assembly also includes a front simulation cabin, which is bolted to the side of the cabin rotating ring opposite to the cabin frame.

[0017] Furthermore, the cabin rotating ring includes two annular side plates spaced apart along its axial direction, and a plurality of pins of the annular pin group are fixed between the two annular side plates. The plurality of pins are arranged at equal intervals along the circumference of the cabin rotating ring, and the axis of each pin is parallel to the central axis of the cabin rotating ring.

[0018] Furthermore, the guide wheel assembly includes a mounting frame, an outer peripheral guide wheel, and an end face limiting wheel. The mounting frame is fixed to the fixed support ring by bolts. The outer peripheral guide wheel and the end face limiting wheel are rotatably mounted on the mounting frame via wheel axles. The outer peripheral guide wheel makes rolling contact with the outer peripheral surface of the cabin rotating ring, and the end face limiting wheel makes rolling contact with the end face of the cabin rotating ring.

[0019] Furthermore, the clearance groove is located between the bottom of the drive housing and the top of the mounting bracket, and the lower part of the pin drive wheel passes through the clearance groove and engages with the annular pin assembly.

[0020] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0021] I. This invention uses a pneumatic motor, transmission gears, pin drive wheels and annular pin assembly to form a flipping transmission structure. The pin drive wheels sequentially move the pins arranged circumferentially along the rotation ring of the cabin, causing the cabin assembly to flip. It has a certain adaptability to local assembly errors and transmission clearances, and can reduce the transmission jamming caused by local deformation or meshing deviation in ordinary gear ring transmission.

[0022] Second, the present invention uses guide wheel assemblies to roll into the outer peripheral surface and end face of the cabin rotating ring, respectively, to provide radial support and axial limit for the cabin rotating ring, so that the cabin rotating ring maintains a stable rotation position during the flipping process, reducing the possibility of displacement or swaying when the cabin rotates.

[0023] Third, this invention connects the rotary encoder and the output shaft of the pneumatic motor coaxially. By detecting the rotation of the output shaft, the flipping state of the cabin assembly is obtained, providing a detection basis for judging the flipping angle of the cabin and stopping control, which is beneficial to improving the repeatability of the cabin position under different training conditions.

[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-5 As shown, this embodiment of the invention provides an emergency rescue underwater escape fully immersive cabin, including a cabin assembly 10, a cabin rotating ring 21, a fixed support ring 22, and a tilting drive mechanism 20;

[0035] The hull assembly 10 includes a hull frame 11, four window frames 12, four escape windows 13, and a hull roof skin 14. The hull frame 11 serves as the load-bearing foundation of the hull assembly 10 and includes longitudinal beams, transverse beams, an arc-shaped top beam, and diagonal bracing beams. The two ends of the transverse beams are welded to the longitudinal beams located on both sides of the hull frame 11, the two ends of the arc-shaped top beams are welded to the corresponding longitudinal beams, and the diagonal bracing beams are welded between the longitudinal beams and the transverse beams to form the frame structure of the hull assembly 10.

[0036] Four window frames 12 are welded to both sides of the cabin frame 11. Each side of the cabin frame 11 is provided with two window frames 12, and the two window frames 12 on the same side are arranged at intervals along the length of the cabin frame 11. Each window frame 12 can be detachably connected to an escape window 13. The escape window 13 is used to form the personnel evacuation position during underwater escape training and can be reinstalled on the corresponding window frame 12 after the training is completed.

[0037] The top skin 14 is fixed to the top of the cabin frame 11; the top skin 14 is an arc-shaped plate structure adapted to the arc-shaped top beam and covers the outside of multiple arc-shaped top beams; a front simulation cabin 15 is also installed at the front end of the cabin frame 11, and the front simulation cabin 15 is fixed to the side of the cabin rotating ring 21 away from the cabin frame 11 by bolts.

[0038] The cabin rotating ring 21 is fixedly connected to the front end of the cabin frame 11, and the cabin rotating ring 21 rotates synchronously with the cabin assembly 10; the fixed support ring 22 is coaxially sleeved on the outside of the cabin rotating ring 21 and is used to install and support the tilting drive mechanism 20.

[0039] The cabin rotating ring 21 includes two annular side plates spaced apart along its axial direction; an annular pin assembly 16 is fixedly installed between the two annular side plates, the annular pin assembly 16 includes a plurality of pins arranged at equal intervals along the inner circumference of the cabin rotating ring 21; the two ends of each pin are respectively fixed to the two annular side plates, and the axis of each pin is parallel to the central axis of the cabin rotating ring 21; the plurality of pins together form a transmission structure extending circumferentially along the cabin rotating ring 21;

[0040] The tilting drive mechanism 20 includes a lifting ring 23, a drive housing 24, a rotary encoder 25, a pneumatic motor 26, a transmission gear 27, a pin drive wheel 28, and a guide wheel assembly 29;

[0041] The lifting ring 23 is located above the drive housing 24. Both ends of the lifting ring 23 are hinged to the top of the drive housing 24 via hinge shafts, allowing the lifting ring 23 to rotate relative to the drive housing 24. The lifting ring 23 is used to connect with an external lifting structure for lifting and lowering the fully immersive cabin.

[0042] The bottom of the drive housing 24 is fixedly connected to the guide wheel assembly 29 by bolts. A clearance groove is provided at the connection between the drive housing 24 and the guide wheel assembly 29. The clearance groove corresponds to the position of the pin drive wheel 28 so that a part of the pin drive wheel 28 can pass through.

[0043] The pneumatic motor 26 is fixedly installed inside the drive housing 24, and the output shaft of the pneumatic motor 26 passes through the drive housing 24; the transmission gear 27 is fixed to the output shaft of the pneumatic motor 26 by a key connection, and the pneumatic motor 26 drives the transmission gear 27 to rotate synchronously when it runs.

[0044] The rotary encoder 25 is fixed to the outside of the drive housing 24 by screws. The detection shaft of the rotary encoder 25 is coaxially connected to the output shaft of the pneumatic motor 26 through a coupling. When the output shaft of the pneumatic motor 26 rotates, the rotary encoder 25 synchronously detects the amount of rotation of the output shaft and outputs a detection signal corresponding to the amount of rotation.

[0045] The pin drive wheel 28 is rotatably mounted in the drive housing 24 via a rotating shaft; a part of the pin drive wheel 28 is located in the drive housing 24 and meshes with the transmission gear 27, and the other part passes through the clearance groove and meshes with the annular pin assembly 16.

[0046] When the pin-driven wheel 28 rotates, its outer peripheral structure sequentially engages with multiple pins in the annular pin assembly 16, thereby pushing the annular pin assembly 16 to move circumferentially along the cabin rotating ring 21. Since the annular pin assembly 16 is fixed to the cabin rotating ring 21, when the annular pin assembly 16 moves, it causes the cabin rotating ring 21 to rotate relative to the fixed support ring 22, thereby causing the cabin assembly 10 to flip.

[0047] The guide wheel assembly 29 includes a mounting frame and multiple guide wheels. The mounting frame is fixed to the fixed support ring 22 by bolts, and the multiple guide wheels are rotatably mounted on the mounting frame via axles. Among them, some of the guide wheels make rolling contact with the outer peripheral surface of the hull rotating ring 21 to provide radial support and guidance for the hull rotating ring 21; the remaining guide wheels make rolling contact with the end face of the hull rotating ring 21 to limit the axial movement of the hull rotating ring 21.

[0048] The guide wheel and the cabin rotating ring 21 are in rolling engagement. During the rotation of the cabin rotating ring 21, multiple guide wheels rotate with the movement of the cabin rotating ring 21, so that the cabin rotating ring 21 is kept within the position range defined by the fixed support ring 22.

[0049] When the present invention is in operation: the fully immersive chamber is connected to the external hoisting equipment through the lifting ring 23, and the chamber assembly 10 is lowered to the training water area; after the trainee enters the chamber assembly 10, the pneumatic motor 26 is started;

[0050] The output shaft of the pneumatic motor 26 drives the transmission gear 27 to rotate, and the transmission gear 27 drives the pin drive wheel 28 to rotate. The pin drive wheel 28 sequentially moves the pins in the annular pin group 16, causing the annular pin group 16 to drive the cabin rotating ring 21 to rotate. The cabin rotating ring 21 is fixedly connected to the cabin frame 11, so when the cabin rotating ring 21 rotates, the cabin assembly 10 flips accordingly.

[0051] During the rotation of the cabin rotating ring 21, the guide wheel assembly 29 maintains rolling contact with the cabin rotating ring 21, supporting and limiting the cabin rotating ring 21; the rotary encoder 25 synchronously detects the rotation amount of the output shaft of the pneumatic motor 26 to determine the flip position of the cabin assembly 10.

[0052] After the hull assembly 10 rotates to the required training position, the pneumatic motor 26 stops running; the trainee completes the underwater escape training through the corresponding escape window 13; after the training is completed, the pneumatic motor 26 runs in reverse, causing the pin drive wheel 28 to reverse the annular pin assembly 16, and the hull rotating ring 21 drives the hull assembly 10 back to the initial position, and the disassembled or opened escape window 13 is reinstalled in the corresponding window frame 12.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
