Description

Technical Field

[0001] This utility model relates to the field of arm-holding mechanism technology, and in particular to an arm-holding mechanism for an underwater propulsion device. Background Technology

[0002] The arm-holding mechanism of an underwater thruster is a key component for achieving a stable connection between the thruster and the underwater vehicle. Its structural design directly affects the applicability, installation efficiency, and operational safety of the equipment. In underwater exploration, rescue, and scientific research, thrusters often need to be changed to different models to meet operational requirements. As the connecting hub, the arm-holding mechanism must ensure the reliability of the thruster's fixation while also being adaptable to thrusters of different sizes. Traditional arm-holding mechanisms mostly adopt a rigid structural design, connecting the thruster to the carrier with bolts. This design has revealed significant limitations in practical applications, especially when adapting to different thruster models, making it difficult to meet the demands of efficient operation.

[0003] Traditional rigid arm clamping mechanisms employ a bolt-fixed structure, with the biggest technical bottleneck being insufficient adaptability to thruster dimensions. This structure is typically customized for specific thruster models, taking into account parameters such as mounting interfaces and diameters. When replacing thrusters with different specifications, the existing arm clamping structure cannot be directly adapted, requiring redesign of the bracket dimensions, mold processing, and adjustment of mounting hole positions. This process not only consumes significant time and cost but also extends equipment downtime for maintenance. In underwater operations, arm clamping compatibility issues can further impact mission efficiency and even lead to operational interruptions. Therefore, a new underwater thruster arm clamping mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an underwater thruster arm mechanism.

[0013] The beneficial effects of this utility model are as follows:

[0014] The vertical position of the lifting plate can be adjusted via the height adjustment mechanism, while the horizontal adjustment mechanism controls the horizontal movement of the connecting plate. Together with the position adjustment mechanism, the height of the support frame can be adjusted, allowing the arm-holding mechanism to adapt to different installation positions of the pushers in three-dimensional space. The first and second arm-holding limiting mechanisms adjust the spacing between the clamping plates via screws, accommodating pushers of different diameters, thus improving the adaptability range compared to traditional fixed supports.

[0015] The tilt angle of the rotating plate can be adjusted by cooperating with the telescopic rod of the adjustment mechanism and the first screw to adapt to the installation requirements of the thruster in different postures. The tilt angle is adjusted after the nut is locked.

At the same time, the clamping force of the screw adjustment is large enough to ensure that the thruster does not loosen when running at high speed. Attached Figure Description
