Description

technical field [0001] The invention relates to an underwater bionic thruster, which belongs to the technical field of underwater thrusters. Background technique [0002] As people's exploration of the ocean continues to deepen, ordinary diving exploration technology can no longer meet human needs for ocean exploration. More and more underwater work is replaced by underwater robots. However, due to the lag in the development of underwater propulsion, Underwater robots cannot flexibly realize various actions in water. For those larger underwater robots, propeller propellers can also be used to move forward, but for those small underwater robots, traditional underwater propellers are no longer applicable, and the underwater environment is complex and changeable, so flexibility is very much needed , High-efficiency underwater propellers enable underwater robots to adapt to changing underwater environments, especially in the fields of oil exploitation, seabed mineral deposit in...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: First, the mechanism is large in size and heavy in weight. Most of the common underwater propellers are designed in one-piece structure. Only the parts can be connected with the underwater robot, which leads to the complex overall structure of the propeller, large volume and weight, which is not conducive to the application of the propeller in the field of small underwater robots; second, the environment is disturbed and noisy, and the traditional propeller The propeller is installed at the tail of the propeller, and the blade is used to drain water backwards to achieve the purpose of advancing. This makes a very loud noise during operation and greatly disturbs the underwater environment; third, the response speed is low and the flexibility is poor. The traditional propeller propeller uses The propeller rotates and drains backwards to achieve power. Due to the huge resistance of the water, the propeller cannot rotate at high speed immediately to make the robot gain explosive power, and the power response is slow
