Description

Technical Field

[0001] The invention relates to the technical field of tugboat navigation, in particular to a device for towing large-scale floating objects on the water surface of a tugboat. Background Art

[0002] Large floating objects usually refer to those large and heavy objects floating on the water. These objects can be naturally formed, such as drifting wood, ice floes, and seaweed clumps, or man-made, such as abandoned ships, floating platforms, offshore structures, and even oil well equipment. They often drift continuously due to factors such as ocean or river currents, wind, and tides, and have strong mobility and uncertainty. Due to their large size, heavy weight, and poor stability, how to effectively track, control, and tow these large floating objects, especially in complex marine environments, is a technical problem in marine operations and shipping. The existence of large floating objects not only poses a threat to navigation safety, but may also have a negative impact on the marine ecological environment. Therefore, the management, cleaning, and disposal of these floating objects have become an important issue in marine engineering and environmental protection.

[0003] In order to safely tow large floating objects such as abandoned ships, floating platforms or other offshore structures to a designated location, a tugboat is usually used for towing. The tugboat connects the rope to the target floating object through a specific towing device. Then, the tugboat starts and slowly begins to tow, ensuring that the distance and tension between the floating object and the tugboat are stable.

[0004] At present, in many traditional tugboats, when encountering danger or needing to urgently detach from floating objects, the cutting of the main towing cable usually relies on manual operation or manual cutting equipment. This method not only relies on manual judgment, but also takes time. Especially in emergency situations, the speed of manual reaction is often slow, resulting in the tugboat being unable to quickly escape from danger or control the situation at an important moment, and personnel will be exposed to dangerous areas. Manual operation has the possibility of accidents. For this reason, technicians in this field have proposed an intelligent mildew-proof grain storage warehouse to solve the above problems. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a device for towing large surface floating objects by tugboats, which solves the problem that the cutting of the main towline usually relies on manual operation or manual cutting equipment when encountering danger or needing to urgently detach from the floating objects.
