Deep-sea triggered active type creature trap and control method

Abstract

The invention belongs to the technical field of development equipment of ocean resources and discloses a deep-sea triggered active type creature trap and a control method. A completely-open type trapping inlet is formed through inserting a pin of a driving mechanism into a center fixing shaft and a center moving sleeve and setting relative positions of a moving frame and a fixing frame; and when the trap performs deep-sea creature trapping on a seafloor, a trigger mechanism is in an open state, the trigger mechanism is in an operating state for closing the trap when bait wrapping the outer side of the trigger mechanism stresses a certain snap-in force, and response is transferred to the driving mechanism in time through a cable. According to the deep-sea triggered active type creature trapand the control method, by adopting the completely-open type trapping inlet, the possibility that deep-sea creatures enter a trapping area is greatly increased; and by adopting the active trigger mechanism, creatures such as fishes can be specifically trapped, timely triggering can be achieved, and thus, rapid control and response are achieved, so that the creature trap has the trapping characteristics of stability, accuracy and rapidness, the pertinency is relatively high, and the success rate of trapping is relatively high.

Description

technical field [0001] The invention belongs to the technical field of marine resource development equipment, and in particular relates to a deep-sea trigger active biological trap and a control method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] With the development of marine resources, the research on deep-sea organisms continues to deepen, and the demand for samples continues to increase. There is an urgent need for stable, accurate and fast biological traps. [0004] Especially in the deep-sea environment, amphipods have more invertebrates than fish and other vertebrates, which have a greater impact on misleading and trapping vertebrates. Moreover, the deep-sea environment endows vertebrates with high sensitivity and requires very high trapping entrances. High, making trapping more difficult. [0005] Existing biological traps mostly adopt static timing closing trapping mode or trawling net ...

AI Technical Summary

Problems solved by technology

[0007] (1) The trapping method of the prior art cannot carry out accurate judgment and timely trapping; before closing the trap, the problem of escaping after eating the bait cannot be effectively controlled by deep-sea organisms

[0008] (2) Most of the trapping openings in the prior art adopt a "flare mouth" structure from large to small, which cannot realize a fully open form. When deep-sea organisms swim to the trapping port, they will only swim around the trapping port, which cannot guarantee sharpness. Deep-sea creatures completely enter the trapping mouth;

[0009] (3) For large-depth trapping, the existing drive mechanism is not only expensive and bulky, but also in a high-pressure environment, the execution force cannot meet the expected requirements at all

[0012] Significance: The current trapping functions are relatively single, and cannot meet the above-mentioned indicators at the same time. A deep-sea trigger active biological trap designed in this design can not only solve technical problems at the same time, realize stable, accurate and fast trapping of deep-sea creatures, but also It provides strong technical support for the development of deep-sea equipment, the development of new marine resources, and the exploration of unknown areas of the ocean.
