Description

Technical Field

[0001] The invention relates to the technical field of underwater exploration, and specifically provides an underwater exploration device. Background Art

[0002] The development of marine resources has great strategic significance. With the development of the marine industry, the ocean will not only become an important resource and energy base for mankind in the future, but also marine geotechnical engineering includes nearshore engineering and offshore engineering. Offshore engineering includes various platforms and submarine pipelines built in shallow or semi-deep seas. Depending on the marine environment and the purpose of construction, the focus of marine geotechnical engineering will also be different. The hydrological environment exploration of the ocean refers to the analysis of the marine environment of the construction area, obtaining the hydrological environment data of the ocean in the area, and judging whether the area meets the construction requirements. The marine hydrological environment exploration includes long-term observation of the ecology of marine benthic animals and plants, so it is necessary to have an underwater exploration device that can work stably underwater for a long period of time. Prior art JP6425086B2 In this invention, in the underwater ground penetration depth measuring device, a cross frame is fixed on the upper end side of the long direction of the penetration probe to be inserted into the underwater ground, and an underwater camera is installed on each arm. The underwater detection component that can move relatively is fixed near the cone on the tip side of the penetration probe. An annular plate is formed at the lower part of the underwater detection component, and when the penetration probe is penetrated, the annular plate is fastened to the surface of the underwater ground. Light-emitting LEDs are installed on the top surface of the plate at 90-degree angle intervals as measuring marks. By photographing the gauge mark with an underwater camera when the penetration probe penetrates the ground, three-dimensional position information depending on the distance change between the underwater camera and the gauge mark is obtained. The penetration depth of the penetration probe into the bottom of the water is calculated by the measuring device based on the three-dimensional position information. The prior art cannot collect image information of biological population activities in the area, and it is difficult to deploy and fix. The inventor believes that there is a large room for improvement in the prior art. Summary of the invention
