The invention provides a magic ball origami bionic jet propeller based on negative pressure, which includes a main part, a power part, a control part, a transmission part and an execution part, and the main part includes a water inlet check valve, a water inlet pipe, and a flexible recovery body And the water spray pipe, the flexible recovery body is a hollow structure with openings at both ends, and the hollow part is the abdominal cavity. The accommodating chamber, the power part is a vacuum pump, the control part is a vacuum solenoid valve, the transmission part includes a suction air pipe and a transmission air pipe, and the execution part includes a closed film and a magic ball origami. The closed film is set in the containing chamber, and the closed film and the containing chamber The wall of the cavity is attached, and the magic ball origami is arranged in the ring-shaped cavity of the closed film. The invention uses the magic ball origami as the executive mechanism, and the flexible recovery body as the recovery mechanism, which is driven in a negative pressure manner and can realize high-efficiency and high-speed propulsion.
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 and need to perform construction, maintenance and survey tasks in more challenging environments, traditional underwater robots can no longer meet the demand. Water jet propulsion is an important propulsion method used by aquatic organisms. They complete the action of water jetting and water absorption by changing the volume of the body cavity, which can not only maintain low energy consumption and high efficiency under long-term swimming speed, but also can swim in bursts. 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 of bionic underwater robots. However, both traditi...
