Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance equipment technology, and in particular to an imaging device for submarine cable maintenance. Background Technology
[0002] With the rise of offshore new energy in China, the offshore wind power industry has developed rapidly. Offshore wind farms are mostly located in near-shore waters, where shipping and fishing activities are frequent. Since submarine cables are often laid directly on the seabed during construction, frequent shipping and fishing activities often cause damage to these cables, leading to the shutdown of a large number of wind turbines and resulting in significant economic losses. Currently, to facilitate the inspection and maintenance of submarine cables, technicians are using underwater robots equipped with detection devices to assess the damage to the cables.
[0003] For example, an underwater robot for submarine cable repair, disclosed in CN217320711U, relates to the field of underwater repair equipment technology. This underwater robot includes: a main body; a first power mechanism mounted on the main body for driving its movement; a manipulator mechanism with its fixed end connected to the main body and its free end equipped with cutting and digging components; a detection and imaging mechanism mounted on the main body for acquiring image information of objects near the underwater robot; and a signal transmission mechanism communicatively connected to the detection and imaging mechanism for transmitting the image information acquired by the detection and imaging mechanism to external devices. When in operation, this underwater robot can approach submarine cables, allowing repair personnel to directly inspect the damage to the cables and providing them with more accurate information.
[0004] The above technical solution has some problems in practical application. When applied, the detection range of the cable is limited, and it is difficult to guarantee the imaging effect of the cable surface during the detection process, resulting in low detection accuracy.
[0005] Therefore, it is necessary to invent an imaging device for submarine cable inspection to solve the above problems. Utility Model Content

The positioning nuts 9 are threaded with the outer side of the positioning screw 7, so that the positioning screw 7 slides horizontally inside the movable tube 8.
[0026] Furthermore, a drive wheel 14 is provided in the middle of the lower surface of the mounting frame 1. The outer side of both the drive wheel 14 and the positioning wheel 5 is provided with an arc-shaped concave structure.
