Ice surface rescue AGV

Abstract

This application relates to the field of ice rescue technology, disclosing an ice rescue AGV (Automated Guided Vehicle) trolley, including a trolley, a rotating shaft, a support column, a cantilever, a pulley, a rope, a lifebuoy, a retractor, and a drive mechanism. In use, controlling the trolley moves it to the hole in the ice. Controlling the drive mechanism rotates the rotating shaft, which in turn rotates the support column, ultimately adjusting the position of the lifebuoy so that it is positioned above the hole in the ice. Then, controlling the retractor releases the rope, allowing the lifebuoy to fall into the water within the hole, providing support to the drowning person and preventing them from sinking to the bottom. Controlling the retractor again retracts the rope, pulling the drowning person out of the hole and completing the rescue. After separating the lifebuoy from the drowning person, controlling the retractor again retracts the rope, lifting the lifebuoy off the ground. Therefore, there is no need to manually reset the lifebuoy, making it easier to use.

Description

Technical Field

[0001] This application relates to the field of ice rescue technology, and in particular to an ice rescue AGV trolley. Background Technology

[0002] A related technology (Announcement No.: CN219545057U) discloses an AGV for ice rescue, including a main body. Tracks are symmetrically arranged on the bottom of the main body. A cable is arranged on the side of the main body away from the camera. A roller is rotatably arranged on the side of the main body near the cable, with the cable wound around the roller, and a retrieval device is arranged on the side of the main body near the roller. Two lifebuoys are arranged on the side of the main body near the cable. A release assembly is arranged on the side of the main body near the lifebuoys, with the two lifebuoys respectively engaged at both ends of the release assembly.

[0003] In the process of implementing the technical solution disclosed herein, it was found that the above technical solution has at least the following problems:

[0004] This ice rescue AGV uses tracks to move its main body across the ice to the location of the drowning victim. A release mechanism then deploys a lifebuoy to the victim's location, facilitating rescues on ice. A retrieval device automatically winds up the cable using rollers, improving rescue efficiency and preventing secondary rescue attempts and dangers on the ice. However, the release mechanism can only deploy the lifebuoy; after the rescue, the lifebuoy must be manually reattached to the release mechanism.

Controlling the drive unit 90 rotates the shaft 20, which in turn rotates the support column 30, ultimately adjusting the position of the lifebuoy 70 so that it is positioned above the hole in the ice. Then, controlling the retractor 80 releases the rope 60, allowing the lifebuoy 70 to fall into the water inside the hole, providing support to the drowning person and preventing them from sinking to the bottom. Controlling the retractor 80 again retracts the rope 60, pulling the drowning person out of the ice hole, completing the rescue. After separating the lifebuoy 70 from the drowning person, controlling the retractor 80 again retracts the rope 60, lifting the lifebuoy 70 off the ground. Therefore, there is no need to manually reset the lifebuoy 70, making it easier to use.
