An underwater fatigue-resistant shock-absorbing device suitable for wave energy glider

Abstract

The invention discloses an underwater fatigue-resistant shock-absorbing device suitable for a wave energy glider, which belongs to the technical field of marine engineering. The shock absorbing device includes a shock absorbing beam, a rectifying block, a limit plate, a shock absorbing beam connecting block, a connecting shaft adapter block and a connecting shaft; the two ends of the shock absorbing beam are sleeved with the shock absorbing beam connecting block and fixed by screws. A rectifier block and a limiting plate are arranged in sequence below the shock absorbing beam, and the connecting bent plate fixes the rectifying block and the limiting plate on the middle section of the shock absorbing beam, and the two connecting shaft adapter blocks are fixed on the shock absorbing beam through the connecting bent plate Above, the two ends of the connecting shaft are rotated and installed on the connecting shaft adapter block through the shaft sleeve; the shock absorbing device is connected with the hanging cable through the connecting shaft, and connected with the glider through the shock absorbing beam connecting block. The invention can effectively reduce the risk of fatigue fracture of the hanging cable, and greatly improve the service period of the wave energy glider.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to an underwater fatigue-resistant shock-absorbing device applied to a glider. Background technique [0002] The development and utilization of the ocean is inseparable from the observation of the ocean environment. The main means of ocean observation are: on-site direct measurement, numerical simulation and satellite remote sensing. The wave glider can be used as an unmanned autonomous ocean observation platform for direct measurement. It has the advantages of navigation survey and platform monitoring. It has simultaneous observation of underwater and aquatic environments, real-time transmission of observation data, and large-scale control without power. Features such as sailing maneuvers or virtual anchoring for long-term fixed-point observations and multi-set network observations. [0003] The wave glider is a marine sports platform driven by wave energy, ...
