The provided is a visualized biological trawl net system based on a submersible. The visualized biological trawl net system based on a submersible includes a fixation frame, and further includes a collection net, a filtering mechanism, a fish school observation camera and a central control system. The collection net is arranged at a rear of the fixation frame and used for collecting marine creatures; the filtering mechanism is arranged inside the fixation frame, and the filtering mechanism is used for screening marine creatures entering the collection net; the fish school observation camera is arranged at a top of the fixation frame, and the fish school observation camera is used for observing marine creatures; and the central control system is electrically connected with the fish school observation camera and used for controlling the fish school observation camera to monitor marine creatures.

A bottom touching assisting device suitable for deep-sea submersibles and an implementation method thereof are provided. Four support columns are arranged within a mounting box body at a bottom of a deep-sea submersible, the support columns and the mounting box body are connected in a sliding manner through sliders, and the support column is sleeved with a threaded sleeve in a threaded connection manner. In conjunction with a drive component and a pressing mechanism, smooth vertical movement of the support column is achieved when the threaded sleeve rotates. This allows a bottom end of the support column to extend from the mounting box body.
