Light deep-sea biological light trapping device based on cam driving

Abstract

The invention discloses a light deep-sea biological light trapping device based on cam driving. The device comprises a trapping cage, a folding door, a door closing mechanism, a power supply control mechanism and a multispectral trapping lamp, the folding door, the door closing mechanism, the power supply control mechanism and the multispectral trapping lamp are connected with the trapping cage, aguide column is arranged at the top of the folding door, and a through U-shaped groove is formed at the top of an opening of the trapping cage. The guide column penetrates through the through U-shaped groove to be connected with the door closing mechanism, the door closing mechanism comprises a concave shell, a guide block, a motor and a cam, a guidance column is arranged at the top in the concave shell, and an elastic pressing device and a guide hole in the guide block are arranged in a matched manner to achieve the limiting and pressing effects; and a limiting column and a guide column limiting column are arranged at the bottom of the guide block, the cam arranged at the bottom of the limiting column is connected with the motor, the motor is connected with the power supply control mechanism, the guide column limiting column is used for limiting the guide column to keep the folding door in an open state, a split round hole is formed in the contact surface of the guide block and the concave shell, a bolt is arranged on the boss of the concave shell, and the bolt is connected with the guide column through 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
