AI Technical Summary
Technical Problem
Existing underwater salvage robotic claws are prone to getting stuck in complex environments due to entangled obstacles, resulting in low grabbing efficiency and equipment damage, and lack of active cleaning capabilities.
Method used
Design an underwater salvage mechanical claw that uses an actively rotating cutting blade to cut through entangled objects, increases the gripping area through an inclined claw plate mounting base and a double single claw plate structure, and achieves stable clamping by combining a magnetic suction component.
Benefits of technology
It effectively avoids entanglement and jamming, improves the continuity and reliability of grasping, and enhances the stability and safety of grasping in complex underwater environments.

Abstract
The underwater salvage mechanical gripper device for fire rescue comprises an operating rod and an operating frame, the bottom of the operating rod is connected with a mechanical gripper mechanism, the mechanical gripper mechanism is connected with an opening and closing mechanism, and the mechanical gripper mechanism comprises a fixed seat and a plurality of inclined gripper plate mounting seats which are uniformly fixed along the outer side of the fixed seat; two single-claw plates are symmetrically and rotationally connected to the outer end of each claw plate mounting seat, and a connecting shaft is fixed to the tops of the two single-claw plates together and connected with the opening and closing mechanism; a cutter is arranged between the two single-claw plates, the top end of the cutter is rotationally mounted in a rotating groove in the lower part of the claw plate mounting seat through a cutter shaft, and the two ends of the cutter shaft extend into the claw plate mounting seat and are connected with a driving assembly; according to the device, the cutting knife is controlled to rotate through the driving assembly, obstacles such as fishing nets and aquatic plants wound on the mechanical claws can be actively cut off, clamping stagnation is avoided, meanwhile, the grabbing stability and reliability are improved through the obliquely-arranged double-claw-plate structure, and the device is suitable for the complex underwater rescue environment.
