Long-endurance submarine sample collection device

Abstract

The invention provides a long-endurance submarine sample collection device which comprises a movement mechanism, a base and a buoyancy mechanism. The base is arranged on the movement mechanism, and the buoyancy mechanism is arranged on the base; an acoustic release is arranged under the buoyancy mechanism, a sample collection mechanism is arranged on the base or the buoyancy mechanism; and a waterflow power generation mechanism is arranged on the buoyancy mechanism. The collection device provided by the invention can utilize the universal water flow power generation mechanism under the sea and utilize submarine water flow in different directions to generate power to store energy for a lithium battery energy storage box inside the collection device so as to meet the long-time working requirement of the collection device, and thus, the activity range of the collection device is enlarged, observation time is prolonged, and both sample collection and movement traveling can obtain sufficient energy supply; and the long-endurance submarine sample collection device not only can implement separate recovery, but also can implement overall recovery, reduces observation cost to the greatestextent, also ensures that precious observation data can be obtained once the base is blocked by submarine foreign matter, and has wide applicability in the field of submarine detection.

Description

technical field [0001] The present invention relates to the technical field of seabed monitoring devices, more specifically, to the technical field of a seabed observation and collection device. Background technique [0002] With the continuous and in-depth research of marine resources by countries all over the world, the focus of competition for the ocean has shifted from the offshore to the deep sea. The deep-sea unmanned submersible is an important marine engineering equipment to realize the development and utilization of the deep sea. Equipped with various electronic equipment and mechanical devices, it quickly dives and floats in the complex environment of the deep sea to realize ocean exploration, scientific research, development, and operation. Ability to maintain marine rights and interests. [0003] For the observation of the deep seabed, currently relatively mature technologies include sediment traps, moored submersible buoy systems, manned submersibles (HOV), ca...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that the sediment catcher in the prior art only has the function of collecting floating sediment, the installation and deployment process of the mooring submersible buoy system is complicated, and the success rate of equipment recovery is also low; the manned submersible (HOV) and the cable control unmanned remote control The submersible (ROV) has a long operating time and high cost, and does not meet the technical problems of large-scale maneuvering operations. The present invention provides a long-endurance seabed sample collection device, which can generate electricity by using water flow to generate electricity for itself. Provide endurance energy for long-term work, and be able to use the crawler mechanism to move autonomously, expand the observation range, obtain regional seabed hydrological dynamics, and improve single-point observations to the surface observation level. The sediment sample cabin and biological capture cabin can store seabed water Rocks, sediments and biological samples, the floating body mechanism made of polymer floating body materials and the inflatable buoyancy mechanism of the base module can realize the overall recovery of the collection device or separate recovery, which can save research costs and ensure data recovery when the base is stuck , has a wide range of adaptability in the field of ocean exploration
