Description

Technical Field

[0001] This utility model relates to the field of tow cable tail marker technology, specifically a tow cable tail marker with flashing function. Background Technology

[0002] A towline is a cable used to tow other vessels or floating bodies. It typically consists of a main towline, short lines, and keel lines (chains). The towline stern beacon is an important component of the towline system, usually installed at the end of the towline to provide positional information and directional indication. In applications such as marine seismic exploration, positioning devices such as Differential Global Positioning System (DGPS), gyrocompass, depth gauge, Relative GPS (RGPS), acoustic bird sensors, and compass birds may be installed on the towline stern beacon. These devices help determine the towline's position at the moment of blasting, thereby improving the imaging accuracy and reliability of seismic data.

[0003] In actual use, towed buoys are equipped with flashlights on their surface to facilitate quick location by staff. However, when used in the ocean, towed buoys often flip over due to external forces such as wind or waves. Once the flashlights are flipped downwards and covered on the sea surface, it becomes difficult for staff to quickly locate them.

[0004] To address the aforementioned issues, we propose a tow cable tail marker with flashing functionality. Utility Model Content
