AI Technical Summary
Existing devices cannot fully conform to uneven bottom surfaces when collecting benthic animals, resulting in some animals not being captured. Furthermore, captured animals are prone to falling off during dragging, reducing collection efficiency.
A benthic animal collection device was designed. The device uses a connecting mechanism between the first and second collection buckets, and a chain and chain ring to adjust the opening angle and position to adapt to different bottom shapes. The through holes increase the chances of animal contact, and the tight connection between the herringbone block and the hook ensures stability.
It improves the flexibility and accuracy of the collection device, increases the capture range, prevents animals from falling, and improves collection efficiency.
