Description

Technical Field

[0001] The present invention relates to a safety rope rescue device, in particular to a safety rope rescue device for marine rescue. Background Art

[0002] Navigation is the human activity of sailing across the ocean, traveling from one landmass to another. In the past, it was a risky endeavor, as human geographical knowledge was limited and the other side was unknown. During maritime rescue operations, fire-resistant safety ropes are required for retraction and deployment. Most existing fire-resistant safety rope retraction and deployment devices for maritime rescue systems tend to become tangled during the retraction and deployment process, delaying rescue efforts and potentially causing irreparable losses. Therefore, a fire-resistant safety rope for maritime rescue is needed.

[0003] For example, the patent with authorization announcement number CN221070528U discloses a fire-resistant safety rope retracting and releasing device for maritime rescue, including a support assembly, wherein a uniformly arranged assembly is installed inside the support assembly. The utility model passes one end of the safety rope through a guide ring, then fixes one end of the safety rope on the retracting and releasing roller, and then rotates the handle. At this time, the handle will drive the entire retracting and releasing assembly to rotate, thereby realizing the reeling of the safety rope. In addition, when the vertical bevel gear ring rotates, since the vertical bevel gear ring is meshed with the horizontal bevel gear ring, the rotation of the vertical bevel gear ring will drive the horizontal bevel gear ring to rotate, thereby driving the eccentric boss to rotate. Since the eccentric boss is inserted into the inside of the strip hole, the rotation of the eccentric boss can drive the moving slide to perform reciprocating linear motion, thereby driving the guide ring to perform reciprocating linear motion. In the process of reeling the safety rope, since the guide ring performs reciprocating linear motion, the safety rope can be evenly reeled on the outside of the retracting and releasing roller. This prior art still has defects: the safety rope needs to be retracted and extended manually, which is difficult to control and dangerous to operate; and there is no locking device, which can easily lead to loss of control of the safety rope.

[0004] In view of this, the present invention designs a safety rope rescue device for marine rescue. Summary of the Invention
