Multifunctional rotary operation tool applied to deep sea ROV

Abstract

The invention discloses a multifunctional rotary operation tool applied to a deep sea ROV, and belongs to the technical field of underwater operation equipment and marine intelligent equipment.The multifunctional rotary operation tool comprises a sealing cylinder, the input end of a brushless motor is connected with a motor driver, an extending shaft of the brushless motor is fixedly connected with an inner rotor through a jackscrew, and the outer wall of the inner rotor is sleeved with an isolation cover; the outer side wall of the isolation cover is connected with an outer rotor in a sleeved mode, a load end bearing is installed between a locking nut and the shoulder of the outer rotor, the right end of the sealing cylinder is sealed through a sealing cylinder rear cover, and a waterproof plug is installed on the sealing cylinder rear cover. According to the tool, the use of non-contact power transmission ensures the complete separation of electronic equipment and seawater, static sealing is achieved through an O-shaped sealing ring, dynamic sealing is not needed, and reliable sealing performance is guaranteed; one set of tool can realize various operation tasks such as cutting, polishing, drilling, quick nut / screw tightening and loosing and the like; and the tool can be used for underwater handheld operation of divers and can also be used for the clamping operation of underwater robots in shallow sea and deep sea environments.

Description

technical field [0001] The invention relates to the technical field of underwater operation equipment and marine intelligent equipment, in particular to a multifunctional rotary operation tool applied to deep-sea ROVs. Background technique [0002] Remotely operated unmanned submersibles (ROVs) are important instruments of a major country that can replace human beings in exploring the ocean and developing ocean resources, and are playing an increasingly important and irreplaceable role in the country's ocean strategy. ROV replaces divers to complete complex and dangerous underwater operations by gripping various underwater tools with manipulators. Its main application scenarios include: rescue and salvage, scientific investigation, laying and inspection of submarine pipelines, inspection and maintenance of underwater structures and Auxiliary operations for underwater construction, etc. In order for ROV to complete accurate and high-quality underwater operations, in addition...

AI Technical Summary

Problems solved by technology

[0005] (1) The hydraulic drive system is used, which has environmental pollution (the working medium is incompatible with the marine environment), complex structure (requires pressure compensation, oil tank and oil return pipe, etc.), poor working reliability (strict sealing requirements, seawater intrusion into the system) Cause oil deterioration, component corrosion and wear) and other problems;

[0006] (2) O-rings, dynamic seals, mechanical seals and end face seals are generally used at the output shaft of the underwater motor, because the output shaft is constantly rotating, especially when rotating at high speed, it is easy to cause wear and heat of the O-ring and deformation, it is easy to leak water under high water pressure; the design of dynamic seal and end face seal is difficult, the processing technology is strict, and there is a gap between the motor shaft and the sealing ring, which will increase the energy friction loss of the motor, and the seal will appear after long-term operation unreliable phenomena;

[0007] (3) The existing underwater tools have a single function, and each set of tools is a relatively large system
