A wave glider cushioning structure

Abstract

The invention relates to the field of wave glider structure design, and discloses a wave glider buffer structure, which includes a surface hull buffer unit and a thruster buffer unit, the water surface hull buffer unit includes a main support column, and the main support column is fixed to the water surface hull connection, the main support column is provided with an upper elastic member, and an upper guide rod is pierced in the middle of the upper elastic member; the thruster buffer unit includes a main beam and a buffer box, the buffer box is fixedly connected with the main beam, and the buffer box is equipped with a lower elastic The middle of the lower elastic member is pierced with a lower guide rod, and the upper guide rod and the lower guide rod are respectively connected with the two ends of the umbilical cable of the wave glider. The design of the present invention cleverly hides the buffer structure in the structure of the surface hull and the underwater propeller, maximizes the use of the space of the wave glider itself, greatly increases the buffer stroke, and can be used without increasing the extra volume of the wave glider. Maximize the effect of cushioning and energy absorption.

Description

technical field [0001] The invention relates to the field of wave glider structural design, in particular to a wave glider buffer structure. Background technique [0002] The wave glider is a new type of unmanned marine vehicle powered by wave energy. It can perform long-term, high-sea tasks such as marine meteorological observation, marine biological research, marine environment monitoring, etc. The wave glider consists of two parts, the surface hull and the underwater gliding propeller, connected by a flexible umbilical cable. The surface hull pulls the underwater gliding propeller to move vertically up and down, and the underwater gliding propeller converts the vertical motion into a horizontal movement and drags the surface hull forward. [0003] Under high sea conditions, underwater glide propulsion, surface hull and umbilical cables will be subjected to extreme impact forces. Although the umbilical cable has certain elasticity and can absorb part of the energy, the ...

Problems solved by technology

However, the wave glider is small in size and needs to absorb a relatively large amount of energy. A large-stroke buffer device will significantly change the appearance and performance of the wave glider, and all structural components of the wave glider are basically exposed in seawater. The buffer device also needs to be considered Corrosion of seawater, adhesion of marine organisms, entanglement of marine debris, etc., bring certain difficulties to buffer design
