A light-weight trapping device for deep-sea organisms driven by a cam

Abstract

The invention discloses a cam-driven light-weight trapping device for deep-sea organisms, which includes trapping cages and folding doors respectively connected to the trapping cages, a door closing mechanism, a power supply control mechanism, and a multi-spectrum lure lamp. The top of the folding door is provided with a guide column. , There is a U-shaped groove on the top of the opening of the trapping cage, and the guide post passes through the U-shaped groove to connect with the door closing mechanism. The door closing mechanism includes a concave shell, a guide block, a motor, a cam, and a guide post on the top of the concave shell. , the elastic pressing device is set in cooperation with the guide hole on the guide block to play the role of limit and compression. The bottom of the guide block is provided with a limit post and a guide post limit post. The cam set at the bottom of the limit post is connected to the motor, and the motor It is connected with the power control mechanism, and the guide post limit post is used to limit the guide post to keep the folding door open. The contact surface between the guide block and the concave shell is provided with a split hole, and the boss of the concave shell is provided with bolts. The guide posts are connected by a tension device.

Description

technical field [0001] The invention relates to the field of marine biological sampling, in particular to a cam-driven portable deep-sea biological light trapping device. Background technique [0002] The acquisition of deep-sea biological samples is extremely important for deep-sea environmental research and the development and utilization of deep-sea biological resources. At present, there is a lack of operating tools for directional capture of seabed organisms and complete samples, which hinders the progress of deep-sea biological scientific research. [0003] Invention patent ZL201610219850.X "Deep-sea biological trap driven by worm and worm motor" discloses a device for closing the door driven by worm and worm, and controls the start of the motor through infrared induction to achieve the effect of trapping in deep sea. The disadvantages of this technical solution are: 1) Only food can be used to trap deep-sea organisms, and photosensitive predators cannot be captured; 2...

AI Technical Summary

Problems solved by technology

The disadvantages of this technical solution are: 1) Only food can be used to trap deep-sea organisms, and photosensitive predators cannot be captured; 2) The closed-cover trapping cage is large in size and heavy in weight, which is not suitable for deep-sea robots and has a small application range; 3) Worm gear The structure has two output ends that cannot be well sealed under high pressure environment, and deep sea operation is easy to cause equipment damage
