Description

Technical Field

[0001] The invention relates to the technical field of marine engineering deep-sea mining equipment, and in particular to a deep-sea sediment bionic sampling device. Background Art

[0002] Marine sediment sampling is an important means of studying the seafloor environment. The ocean covers about 70% of the Earth's surface, and this vast area is being actively explored. Observations of the seafloor have confirmed the existence of a variety of marine resources in the deep sea. However, the reserves of most seafloor resources and the generation mechanism of seafloor resources have not yet been clearly explored. In order to clarify the reserves and formation mechanism of seafloor resources, it is necessary to collect marine sediment samples over a large area and conduct detailed investigations. Sampling of deep-sea sediments includes the following functions: 1. Mineral distribution indication: The composition and structure of deep-sea sediments can reflect the distribution of seabed minerals. For example, the sediment composition and grain size characteristics of polymetallic nodule areas (deep-sea manganese nodule areas) can serve as an important reference for mineral exploration; 2. Supplementary exploration methods: Through the study of microorganisms in deep-sea sediments, the existence of seabed energy can be inferred. This biogeochemical exploration method is an effective supplement to traditional exploration methods and helps to discover new seabed mineral resources; 3. Marine Engineering Foundation: The geomechanical properties of deep-sea sediments have an important impact on marine engineering projects such as the laying of submarine cables and oil pipelines, the design and construction of oil drilling platforms, etc. Testing and analyzing the physical and mechanical properties of sediments can provide a scientific basis for marine engineering.

[0003] At present, some existing domestic patent technologies have proposed methods and means for sampling deep-sea sediments. Due to the complexity of deep-sea sediment sampling conditions and the arduousness of sampling work, the relevant technologies still have major problems and need to be further improved. The main problems of deep-sea sediment sampling devices are: 1. In the general sampling method, equipment such as drilling rigs and pipelines penetrate the seabed from the ship and collect sediments. Existing exploration equipment must use large ships as mother ships to carry the equipment, which is very expensive to mine. 2. Most of the existing sampling equipment is fixed sampling equipment, which has no autonomous mobility and cannot perform continuous and systematic sampling. In addition, the search range is limited to relatively fixed points, which makes it difficult to meet the requirements of systematic and continuous deep-sea sediment engineering sampling. The original sampling method is inefficient; 3. Existing sediment sampling devices are generally greatly affected by the marine environment, such as ocean currents, tides, waves, etc. Since the sampling device is connected to the ship through a cable, it will be affected by ocean currents, tides, waves, etc., resulting in inaccurate sampling or insufficient sampling; 4. Most of the existing sediment sampling devices are single-direction sampling devices, which do not have the conditions for multi-angle sampling and cannot meet the requirements for multi-angle and multi-directional sampling of deep-sea sediments; 5. Most of the existing deep-sea sediment sampling technologies lack intelligent identification and path planning for deep-sea sediment sampling, resulting in low sampling efficiency and poor quality of the samples taken. Summary of the invention

[0004] Based on the problems and shortcomings of the above-mentioned existing patent technologies, the present invention proposes a bionic sampling device for deep-sea sediments. In terms of equipment, the sampling device is separated from the mother ship and is fixed and regulated by a base station, which greatly saves the high cost caused by the long-term deployment of ships and improves the sampling efficiency; a creeping propulsion system is added to the sampling device, which enables more flexible sampling. In terms of intelligence, the sampling device is installed with a variety of intelligent sensors and is equipped with corresponding intelligent control systems, which can effectively collect and process information, effectively improve the sampling efficiency, and the quality of the samples.

After the third part has moved forward, the anchoring component of the third part expands and returns to its original state. At this time, the device as a whole moves forward, including the excavation sampling system inside the creeping propulsion system. This is a complete creeping propulsion process of the device, and the working conditions of the entire device are adjusted in real time by the intelligent control system during the propulsion process; Step 9: After the intelligent sensor inside the excavation sampling system detects that the deep-sea sediments that meet the standards have been collected, the sampling sealing components located at the front and back ends of the entire excavation sampling system will seal the entire excavation sampling system to ensure the integrity and systematicness of the sampled material; Step 10: After sampling is completed, the entire sampling device returns to its original path, and the intelligent control system sends a signal to the staff to locate the position of the entire device, which is then salvaged by the corresponding vessel to harvest the corresponding deep-sea sediment samples.
