[0006] This technical solution features a hemispherical pressure hull and a hemispherical observation window, secured together by first and second radial extensions and several fastening bolts. The entire cabin is spherical to reduce stress concentration. The hemispherical pressure hull and observation window form the main structure of the manned cabin, designed to withstand the immense water pressure of the deep sea and protect the personnel and equipment within. The optimized structure of the manned cabin improves overall stability and enhances the submersible's stability during deep-sea operations. The observation window provides a window for personnel to observe the external deep-sea environment. A discharge device is located at the bottom of the hemispherical pressure hull. This device is designed to jettison the payload and allow the manned cabin to ascend under its own buoyancy in the event of a dangerous deep-sea operation. This device provides high reliability and strong load-bearing capacity to cope with the complexity and uncertainty of the deep-sea environment. The hemispherical pressure hull is equipped with a hatch assembly, which serves as the entrance and exit of the manned cabin, allowing personnel to enter and exit and equipment to be loaded and unloaded. A sealing ring is located between the first and second radial extensions to ensure a tight seal between the various components of the manned cabin and prevent dangerous seawater infiltration. Several fastening bolts are circumferentially arranged between the first radial extension portion and the second radial extension portion. The fastening bolts are located on the outside of the sealing ring. One end of the fastening bolts is provided with a gasket, and the other end is provided with a nut. It can firmly connect the hemispherical pressure shell and the hemispherical observation window together, and further improve the sealing of the manned cabin through the sealing ring.
[0007] Furthermore, in order to improve the structural stability of the first radially extending portion, a plurality of reinforcing plates are evenly arranged circumferentially between the first radially extending portion and the hemispherical pressure shell.
[0008] Furthermore, the hemispherical pressure hull is made of EH36 marine steel plate, so that the hemispherical pressure hull can significantly improve its ability to withstand deep-sea pressure while maintaining its lightweight.
[0009] Furthermore, the hemispherical observation window is made of polymethyl methacrylate, which is highly transparent, scratch-resistant, and high-pressure-resistant, to improve the pressure resistance and impact resistance of the observation window, ensuring the safety and reliability of the observation window in deep-sea environments.
[0010] The beneficial effects of the present invention are as follows: In this technical solution, the hemispherical pressure hull and the hemispherical observation window are fixed together by a first radial extension, a second radial extension, and a plurality of fastening bolts. The entire cabin body is spherical to reduce stress concentration. The hemispherical pressure hull and the hemispherical observation window constitute the main structure of the manned cabin, which is used to withstand the huge water pressure of the deep sea and protect the safety of personnel and equipment inside. The optimization of the manned cabin structure improves the overall stability and enhances the stability of the submersible during deep-sea operations. The observation window provides a window for personnel inside to observe the external deep-sea environment. The lower portion of the hemispherical pressure hull is provided with an unloading device, which is mainly used to discard the load and allow the manned cabin to float up by its own buoyancy when the submersible encounters dangerous conditions during deep-sea operations. It has high reliability and strong load-bearing capacity to cope with the complexity and uncertainty of the deep-sea environment. The hemispherical pressure hull is provided with a hatch assembly, which is the entrance and exit of the manned cabin and is used for personnel entry and exit and equipment loading and unloading. A sealing ring is located between the first and second radial extensions. This ring ensures a tight seal between the various components of the crew cabin, preventing dangerous seawater infiltration. Several fastening bolts are circumferentially located between the first and second radial extensions. These bolts are located outside the sealing ring, each with a washer at one end and a nut at the other. These bolts securely connect the hemispherical pressure hull and the hemispherical observation window, further enhancing the crew cabin's tightness. BRIEF DESCRIPTION OF THE DRAWINGS
