Description

Technical Field

[0001] The present application relates to the field of ocean exploration, and in particular to a device for detecting seabed obstacles. Background Art

[0002] In marine survey projects, geophysical exploration is required to identify the distribution of rock and soil layers and their physical and mechanical properties within the influence range of offshore structures, as well as adverse geological phenomena that affect foundation stability. However, due to the construction of ports, waterways, docks and other projects, there are obstacles such as fishing nets, wooden piles, and drainage pipes in shallow water areas. Geophysical exploration equipment needs to go more than 1 meter deep into the water when working, so it is easy for geophysical exploration equipment to collide with obstacles in shallow water areas, causing damage to the geophysical exploration equipment. Therefore, it is necessary to check for obstacles on the seabed before conducting geophysical exploration operations.

[0003] Prior art CN108445552A discloses a device and method for checking submarine obstacles, the device comprising: an elastic member arranged on a hull, a resistance meter, and a resistance strain gauge arranged on the elastic member, the resistance strain gauge being electrically connected to the resistance meter. The elastic member is a frame structure, the elastic member is used to contact the seawater and submarine obstacles in the sea area to be checked, and undergoes elastic deformation after contact, the resistance strain gauge undergoes a change in resistance value under the influence of the elastic deformation, and whether there is an obstacle can be known according to the data change of the resistance meter. The device has a simple structure and is easy to use. The frame-type elastic member increases the area for checking obstacles and improves the efficiency of checking submarine obstacles. However, the frame-type elastic member is easily entangled by marine garbage or algae in shallow waters during movement, and the cleaning process is cumbersome. After detecting an obstacle, the elastic member changes the running direction of the ship to reduce the phenomenon of entanglement and knotting between the elastic member and the obstacle, thereby affecting the efficiency of obstacle checking.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the elastic member is prone to entanglement with obstacles, marine debris or seaweed during movement, thereby affecting the efficiency of detecting seabed obstacles. Utility Model Content
