AI Technical Summary
Technical Problem
Traditional propellers are heavy, prone to corrosion, and have a fixed pitch that cannot be adjusted, resulting in high energy consumption, unstable operation, and inconvenient maintenance.
Method used
The spiral blades are made of lightweight carbon nylon material and adaptive pitch is achieved through a spiral device and adjustment device. Fluid pressure drives the trapezoidal plug and passive plate to change the angle of the spiral blades, and a compression spring provides buffering and restoring force.
Benefits of technology
It significantly reduces propeller weight, improves operating efficiency, has strong corrosion resistance, automatically adjusts pitch to adapt to different working conditions, reduces energy consumption, extends service life, and is easy to maintain.

Abstract
The utility model discloses a variable pitch propeller based on a light carbon nylon material, which relates to the technical field of propellers, and comprises a central circle, a plurality of spiral devices and a plurality of light carbon nylon materials, the spiral device is arranged, the spiral blades are made of light carbon nylon materials, the overall weight of the propeller is remarkably reduced, energy consumption during equipment operation is reduced, meanwhile, the carbon nylon materials have good strength and corrosion resistance, the propeller can stably and reliably operate in the severe environment, abrasion and corrosion are effectively resisted, and the service life of the propeller is prolonged. When a fluid rushes into the cavity, the trapezoidal plug moves to drive the pull rod to move, so that the passive plate displaces, and finally the spiral blade is driven to change the angle, and the self-adaptive pitch changing effect is achieved, so that the propeller pitch of the propeller can be automatically adjusted according to the actual condition of the fluid; the compression spring can provide certain buffering and resetting force.
