Underwater mechanical arm

Abstract

The invention discloses an underwater mechanical arm. The underwater mechanical arm comprises a cabin, a telescopic drive piece, clamping claws and guide rods. The telescopic drive piece is arranged in the cabin arranged in a sealed manner. The guide rods are in sealed sliding connection with the cabin. One ends of the guide rods are connected with the telescopic executing end of the telescopic drive piece, the other ends of the guide rods are hinged to one ends of the clamping claws, and the other ends of the clamping claws are hinged to the cabin. The multiple clamping claws conduct clampingor loosening along with the process that the telescopic drive piece drives the guide rods to stretch and contract. A motor and lead screw transmission manner is adopted for driving, the four-claw linkage manner is used for achieving the underwater object grabbing function, the mechanical arm function is achieved through a simple structure, and the cost and operation difficulty are reduced. Meanwhile, a complete watertight structure is achieved, stability of underwater automatic operation is improved, the difficulty of underwater fishing work is effectively lowered, the application field of anunderwater robot is widened, and wide popularization value is achieved in the fields of water surface management, underwater fishing and the like.

Description

technical field [0001] The invention relates to the field of underwater equipment, in particular to a novel underwater manipulator with reliable sealing and simple structure. Background technique [0002] At present, with the utilization and development of marine resources, underwater manipulators are more and more widely used, and manipulators that can withstand a certain water pressure and work smoothly have emerged as the times require. Existing underwater manipulators generally consist of three parts: drive part, transmission part and end effector part. The driving part drives the transmission part, and the transmission part converts the rotary motion of the driving part into a linear motion, so as to achieve the purpose of clamping the target object. [0003] The key structure of the underwater manipulator lies in the transmission part and the end effector part. The existing transmission mechanism generally has a complex structure, the transmission stability is averag...

AI Technical Summary

Problems solved by technology

The existing transmission mechanism is generally complex in structure, the transmission stability is average, and it is prone to failure; when the end effector grabs the target object, the stability is not enough, and the target object is easy to shake or even fall

Furthermore, the existing underwater manipulator has a poor sealing effect under high water pressure, and cannot complete the task well; and with the vibration generated when the manipulator is working, the sealing performance will be further reduced
