Problems solved by technology

Manned submersibles dive deeper and deeper, and a variety of large plankton are found during the dive. However, because they are in motion, there is no corresponding equipment to capture them, and many opportunities for deep-sea biological research have been missed.

Abstract

The invention belongs to the technical field of deep-sea life sampling, and particularly relates to a life sampling device. A net launching type large aquatic life sampler comprises a triggering mechanism, a launching mechanism, a net storage device and a sampler shell. According to the technical scheme, the triggering mechanism is installed at the bottom of a barrel body (22) of the sampler shell through a base body (23) of the triggering mechanism, a pushing shaft (5) is located inside the barrel body (22), the top of the pushing shaft (5) is hinged to a pushing rod (9) corresponding to a spear (12) in the launching mechanism, the pushing rod (9) is connected with a sliding block (18), and the sliding block (18) moves in a sliding groove (25) and is connected with a safety pin (10) at the bottom of the spear (12) in the launching mechanism. The launching mechanism is installed on the conical top surface of the barrel body (22) through a launching pipe (14) of the launching mechanism, the net storage device is installed in the center of the conical top surface of the barrel body (22), and a fishing net (15) in the net storage device is connected with the spear (12) through a net wire. According to the net launching type large aquatic life sampler, only the mechanical structure is adopted, and motion is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of deep-sea biological sampling, and in particular relates to a biological sampling device. Background technique [0002] There are all kinds of organisms in the ocean. During the 15th and 11th Five-Year Plans, a lot of research has been done on marine biological sample collection technology. A large number of key technologies have made breakthroughs. The TV grab, visual multi-tube sampler, and deep-sea biological combination have been successfully developed. Sampler, deep sea water filter, deep sea hydrothermal sampler, sediment fidelity sampler and other collection equipment. At present, shallow sea biological sampling methods are relatively mature, and the types of samplers are relatively complete. With the advancement of technology, ROVs or manned submersibles can now reach deep sea locations. However, most of the traditional sampling equipment is relatively large in size and weight, and the mechanism is...
