Intelligent visual classified sampling device for capturing deep sea benthos

Abstract

The invention discloses an intelligent visual classified sampling device for capturing deep sea benthos, which comprises a deep water detection part, a sampling mechanism and a cable, and is characterized in that the sampling mechanism comprises a pressure-resistant cylinder with two open ends and a sampling cavity inside, and the pressure-resistant cylinder is provided with a semicircular door body for opening and closing a sampling port; the first control mechanism is used for driving the semicircular door body to be opened and closed, limiting devices and a second control mechanism are arranged in the pressure-resistant cylinder, the limiting devices are sequentially closed after the deep-sea-bottom benthos enter the pressure-resistant cylinder, and the captured deep-sea-bottom benthos are sequentially classified and isolated through the limiting devices, and the second control mechanism is used for driving the limiting devices to be opened and closed. A water pump paddle for providing reverse siphon force into the pressure-resistant cylinder is arranged on the sealing component. The detection element is used for detecting the quantity of the captured deep-sea benthos, the operation of the three-stage telescopic oil cylinder is automatically controlled through a controller signal, and the purposes of automatic multi-time capturing, large-quantity capturing and classified capturing are achieved.

Description

technical field [0001] The invention relates to the technical field of marine biological resource sampling, in particular to an intelligent visual classification sampling device for capturing deep sea-dwelling organisms. Background technique [0002] Deep-sea biological sampling is one of the basic means of deep-sea environment and resource investigation. The development and utilization of marine biological resources are of great significance to scientific progress, economic construction, environmental governance and medical development. However, the biodiversity of marine living resources and the specific natural products they produce have just begun to come into people's field of vision. There are a large number of microorganisms and multicellular organisms in the ocean, and their great diversity has become a huge treasure house of biological natural products. Deep-sea biological samples contain rich biological information, which is of great significance to the research o...

Problems solved by technology

[0008] The above-mentioned patented technology has greatly promoted the technological development of marine deep-sea biological exploration and research. Although the current deep-sea biological sampling equipment can realize the capture of seabed organisms, there are still some defects. If the box door structure is adopted, it is easy to catch the fish by opening the box door again. Causing the escape of seabed creatures, the piston structure cannot catch larger seabed creatures, and most of the current deep-sea trapping devices cannot repeatedly capture seabed creatures, and they cannot be classified when catching creatures, such as catching blind fish , Blind shrimp, blind fish and blind shrimp after capture are mixed together, and cannot be classified and captured separately. Often, the captured organisms are easy to escape when the door is opened again, resulting in a single entry into the seabed.
