Deep sea oil seal propeller

Abstract

The invention provides a deep sea oil seal propeller, and the application target is oriented to an underwater robot. A compensator and a propeller are made into an integral structure, a frameless motor is used as a power part, adjacent shells are connected by adopting a manner that bosses and threaded wires (non-metal wires) are connected and matched, aluminum-magnesium-zinc alloy blocks are adopted at the contact between aluminum alloy and stainless steel, a graphite copper sleeve is arranged at the tail end of the output shaft, a self-compensating structure is arranged at the head, a filterscreen is arranged at the water inlet, and a preload spring is arranged at a compensation device. The deep sea oil seal propeller has the beneficial effects of compact structure, convenience in installation, reliable performance, convenience in oil-filling, reasonable design and the like, the integral design of the deep sea oil seal propeller is realized, and facilitation of the deep sea propelleris made possible.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to a deep-sea oil-sealed thruster. technical background [0002] With the continuous deepening of people's understanding of the ocean, the diving depth of underwater vehicles is also increasing, and most deep-sea propellers use oil pressure compensation, but the propeller and compensator in oil-sealed propellers are two separate parts , the oil pipe is connected in the middle, which increases the difficulty of the installation and layout of the propeller, and the aging of the oil pipe will increase the risk of leakage. Obviously, it is a great safety hazard for high-cost underwater vehicles, so the integrated deep-sea oil-sealed propeller is the future. Development trend, researching a practical deep-sea oil-sealed thruster is one of the important issues in the field of underwater robot technology.

Problems solved by technology

[0002] With the continuous deepening of people's understanding of the ocean, the diving depth of underwater vehicles is also increasing, and most deep-sea propellers use oil pressure compensation, but the propeller and compensator in oil-sealed propellers are two separate parts , the oil pipe is connected in the middle, which increases the difficulty of the installation and layout of the propeller, and the aging of the oil pipe will increase the risk of leakage. Obviously, it is a big safety hazard for high-cost underwater vehicles, so the integrated deep-sea oil-sealed propeller is the future. Development trend, researching a practical deep-sea oil-sealed thruster is one of the important issues in the field of underwater robot technology

[0003] At present, domestic oil-sealed propellers adopt the method of separate connection of propeller and compensator, which is complicated to install, troublesome to fill oil, and has potential safety hazards. Therefore, a practical deep-sea oil-sealed propeller has become one of the main problems for technological breakthroughs.
