Description

Technical Field

[0001] The utility model relates to the technical field of propellers, in particular to a propeller experience device. Background Art

[0002] A propeller is a device that converts the engine's rotational power into propulsion by rotating its blades in a fluid. When the propeller rotates at high speed, it will generate strong airflow, which will push objects to move. The propeller device is an important component of aircraft, ships and other devices.

[0003] Among them, in order to allow people to truly feel the thrust generated by spiral motion, a propeller experience device appeared in the science and technology exhibition hall. The existing propeller experience device uses manpower as the power source and uses a conductive structure to drive the propeller to rotate. When the propeller rotates, the experience mechanism body will gradually accelerate. When the movement of the experience mechanism body needs to be stopped, the experiencer needs to stop applying external force until the propeller stops naturally, which is not conducive to braking the experience mechanism body at any time in unexpected situations. For this reason, we propose a propeller experience device. Utility Model Content

[0016] The utility model brakes the experience mechanism body in a rotating state through a brake component, and protects the experiencer through a protective component. In the brake component, the clamping rod is driven by an elastic member to move downward along the cavity of the mounting shell, and the brake wheel in the bracket contacts the grinding pad.
