The invention provides a magic ball paper folding type bionic jet propeller based on a negative pressure, which comprises a main body part, a power part, a control part, a transmission part and an execution part, the main body part comprises a water inlet one-way valve, a water inlet pipe, a flexible restoring body and a water spraying pipe, the flexible restoring body is of a hollow structure with the two ends open, and the hollow position is an abdominal cavity; the water inlet pipe and the water spraying pipe are installed in openings in the left end and the right end of the flexible restoring body respectively, a containing cavity surrounding the abdominal cavity is further formed in the flexible restoring body, the power part is a vacuum pump, the control part is a vacuum electromagnetic valve, the transmission part comprises an air exhaust air pipe and a transmission air pipe, and the execution part comprises a sealing film and magic ball folded paper. The sealing film is arranged in the containing cavity and attached to the cavity wall of the containing cavity, and the magic ball folded paper is arranged in an annular inner cavity of the sealing film. The magic ball folded paper serves as an executing mechanism, the flexible restoring body serves as a restoring mechanism, driving is conducted in a negative pressure mode, and efficient and high-speed propelling can be achieved.
Description
technical field [0001] The invention belongs to the technical field of bionic robots, in particular to a magic ball origami bionic jet propeller based on negative pressure. Background technique [0002] As people continue to explore the ocean, they need to perform construction, maintenance and survey tasks in more challenging environments, and traditional underwater robots can no longer meet the needs. Water jet propulsion is an important propulsion method adopted by aquatic organisms. They complete water spraying and water absorption by changing the volume of the body cavity. At the same time, it has the characteristics of low operating noise, high propulsion efficiency, and small attachment resistance. Therefore, the biological water jet propulsion mode has once become a research hotspot for bionic underwater robots. However, whether it is a traditional drive represented by a motor or a new intelligent drive represented by a shape memory alloy (SMA), there are inevitably ...
