Underwater bionic jellyfish based on fluid conveying pipe driving

Abstract

The invention discloses an underwater bionic jellyfish based on fluid conveying pipe driving and belongs to the field of underwater robots. The underwater bionic jellyfish comprises a head part and atentacle part, wherein the head part comprises a sealed shell, a control module, a water pump, a flow control valve, an in-cavity fluid conveying hard pipe, a multi-way connector and an in-cavity fluid conveying hose; these structures are fixed inside a sealed cavity; the tentacle part comprises multiple fluid conveying hoses for the tentacle part and soft springs; and each of the fluid conveyinghoses for the tentacle part extends naturally in an original state, and the fluid conveying hose for the tentacle part is tensioned by each of the soft springs to be bent. The underwater bionic jellyfish disclosed by the invention is based on a bionics structure of jellyfishes; the fluid conveying hoses are taken as tentacles and get bent and deformed by the springs; then, under force generated from water pumping by the water pump, the fluid conveying hoses are driven to extend or discharge water by fluttering to produce push force, so advancing is realized and thus a motion structure of the bionic jellyfish is simplified; practicability and economic performance are improved; the underwater bionic jellyfish is energy-saving and environment-friendly; noise is small; efficiency is high; thesize is small; and the jellyfish is flexible and mobile.

Description

technical field [0001] The invention belongs to the field of underwater robots, and more specifically relates to an underwater bionic jellyfish based on a delivery tube. Background technique [0002] The ocean is not only rich in food, minerals and other resources, but also an important transportation channel and military strategic space. Therefore, the 21st century is also known as the "Ocean Century" in which humans exploit and utilize the ocean. Since human beings cannot move underwater for a long time and in a large area, they need to use equipment such as submarines, submersibles, and underwater robots to further explore and understand the ocean world. Among them, underwater machines have been widely used in marine scientific investigation, marine environmental monitoring and survey, underwater operations, mariculture and other fields, and have important economic value and military significance. [0003] In the early days, underwater robots basically used propeller pr...
