Background
The existing propeller speed regulator has no propeller overspeed protection function, and when the propeller overspeed reaches a certain value, particularly in the process from positive propeller to negative propeller, the propeller is easy to fly and rotate, so that an accident happens to an airplane. In order to ensure the use safety of the airplane and prevent the propeller from flying, a propeller control system is provided with a highest rotating speed limiting mechanism, some speed limiting mechanisms are contained in an engine or a propeller structure, and sometimes, because the space structures of the engine and the propeller are limited or the requirements of functional modularization are met, the speed limiting function can be separated out and designed as an independent product. The existing speed limiter is either electric-controlled or hydraulic, the structure is simple, the speed-limiting rotating speed is single, the response is slow, especially in a reverse-oar state, the required working rotating speed of a propeller is lower than that of a forward oar, if the propeller exceeds the speed, the speed limiter cannot respond in time because the working point of the speed limiter is not reached, and once a fault occurs, the propeller cannot be prevented from over-rotating in time, so that an airplane accident is caused. In order to ensure that the airplane is used more safely and reliably, a more reliable overspeed protection function is urgently needed to be added.

When the speed regulator is installed, after the speed regulator is overspeed to a certain value, the power turbine regulating assembly is acted, the valve core and valve cap assembly is lifted to a certain degree, the shifting fork is pushed to rotate, the counter weight presses the baffle of the baffle support assembly to open the nozzle, and the pressure on one side in the signal conversion device is reduced to give a signal to the fuel oil regulator, so that the oil supply amount to the engine is reduced, the power of the engine is reduced, the rotating speed of the propeller is also reduced to a required range, and the propeller is prevented from flying. When the propeller is operated and reversed, the reset handle acts, the supporting rod moves downwards, the counterweight block presses the baffle plate of the baffle plate support assembly to open the nozzle, the pressure at one side in the signal conversion device is reduced, a signal is sent to the fuel regulator, the fuel supply quantity to the engine is reduced, the power of the engine is reduced, the underspeed condition of the propeller occurs, and the propeller moves towards the direction of the reverse propeller.
The installation of the invention ensures that the speed regulator has the function of protecting the overspeed of the propeller, thus ensuring the work of the propeller to be more reliable and the use of the airplane to be safer and more reliable. The invention also has the auxiliary functions of beta manipulation and reverse paddle.
