Description

Technical Field

[0001] This invention relates to the field of AUV pressure chamber auxiliary device technology, specifically to a support device for an AUV pressure chamber cylinder. Background Technology

[0002] Autonomous underwater vehicles (AUVs) are a type of unmanned underwater vehicle (UUV), belonging to a new type of underwater unmanned platform. They can carry various sensors and mission modules and have advantages such as autonomy, stealth, environmental adaptability, deployability, and cost-effectiveness. Due to the advantages of cylindrical pressure hulls in facilitating the internal arrangement of components and modules and achieving high space utilization, they are widely used in AUVs.

[0003] Currently, most cylindrical pressure chambers on the market are machined from a single piece of bar stock and lack internal mounting elements such as fixing holes. Therefore, adhesives are often used to fix the support device to the inner wall of the pressure chamber or the end cover plate. When the AUV is operating unstablely, the support device may detach from the inner wall of the pressure chamber, causing the support device to move or shake, affecting the normal operation of components and mission modules. When maintenance or sensor wiring is required, the end cover plate of the pressure chamber must be completely disassembled from the support device, resulting in low work efficiency. In addition, disassembling the support device may damage components and mission modules, increasing the difficulty of component repair, maintenance time, and repair costs. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a support device for the pressure chamber shell of an AUV. The device has a simple structure and uses movable parts and connectors to allow the support device body to move radially along the pressure chamber shell, enabling installation and disassembly without damaging components or mission modules.

[0043] Working principle of the invention:

[0044] 1) The process of fixing the support device body 3 inside the pressure chamber 1: The support device body 3 is placed inside the pressure chamber 1 through the D-ring 303, and then the vertical plate 302 is adjusted until the fitting contour set on the outside of the vertical plate 302 fits the inner wall of the pressure chamber 1; then the screw 601 is rotated clockwise to drive the locking slider 3043 to move towards the fixed base 3041, and the moving slider 3042 is squeezed to make the moving slider 3042 slide out of the first groove on the fixed base 3041, move radially away from the fixed base 3041 along the inside of the pressure chamber 1 until the moving slider 3042 moves to the inner wall of the pressure chamber 1, thus realizing the fixed support of the support device body 3;

[0045] 2) The process of disassembling and removing the support device body 3 from the pressure chamber 1: Rotating the screw 601 counterclockwise drives the locking slider 3043 away from the fixed base 3041. At this time, the moving slider 3042 moves radially along the inside of the pressure chamber 1 under the preload of the compression spring 8 until it enters the first groove on the fixed base 3041. At this time, the vertical plate 302 moves away from the inner wall of the pressure chamber 1 during the movement of the movable unit to ensure that the support device body 3 is in the middle position inside the pressure chamber 1. Then, the support device body 3 is removed from the pressure chamber 1 through the D-ring 303.

[0046] 3) The connecting rod 602 ensures that multiple moving units operate synchronously, which facilitates operation and improves work efficiency.

[0047] The support device of this invention has floating ends, and the outer contour of the vertical plate radially expands and contracts to fit the inner wall of the pressure-resistant chamber. Multiple axially arranged movable units can be flexibly combined, and the screw head drives the screw and connecting rod to rotate, thereby simultaneously tightening and loosening the multiple movable units. This design offers high reliability, simple operation, and strong adaptability. Furthermore, the heating element is located on the support plate. During operation, the heat emitted by the heating element is conducted sequentially along the support plate, the outer contour of the vertical plate, to the inner wall of the pressure-resistant chamber, and then to the outside, improving heat conduction efficiency and meeting the heat dissipation requirements of high-power, high-heat-flux-density heating elements.

[0048] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the principles and essence of the present invention should fall within the protection scope defined by the claims of the present invention.
