Table 5.
Design choices and details.
| Selected organism or part | Detail |
|---|---|
| Bamboo | The shape of bamboo is cylindrical and similar to that of the reel in the winch. The arrangement of bamboo fiber bundles is a ring-shaped mesh hollow structure, which can be realized on the inner and outer walls of the reel. The hollow structure of the first-round tube can reduce the overall weight of the winch and is convenient for handling. The inner and outer wall structures can improve the structural strength and avoid deformation under compression |
| Rhizomes and pointed stems of plants | The hydration of rhizomes and tip stems can cause cell walls to expand and contract, similar to retractable air sacs. This kind of bionic airbag structure is added into the groove, the steel wire rope is in contact with the first round tube, the airbag is deformed under pressure, the contact area between the first round tube and the steel wire rope is increased, and the friction force can be increased |
| Mushroom | There are many covering layers on the mushroom surface, and the covering layer is designed on the first-round tube with rubber bumps to prevent the wire rope from slipping |
| Snake's abdomen scales | Abdomen scales are like an inverted V structure. This inverted V structure is designed on the rotating shaft with a ratchet and pawl. When the drive motor suddenly loses power, the weight loses the pulling force and falls, and the rotating shaft is impacted in one direction. At this time, the pawl restricts the ratchet from turning Rotate to avoid accidental falling of heavy objects |
| Honeycomb structure | The hexagonal structure of the honeycomb is designed in a bionic design on the inner wall reinforcing plate of the reel to improve the strength of the first-round tube |
| The shell on the back of the Beetle | The shell of the beetle is mostly arc-shaped. The arc-shaped structure is used as the arc-shaped pressure plate of the winch. When the winch drags the heavy object, the steel wire rope releases the specified length, and the arc-shaped pressure plate is moved down and pressed by the lifting structure. The steel wire rope of the first-round tube avoids the relative sliding of the steel wire rope and improves the working stability of the winch |
