Problems solved by technology
Because the flight environment of the aircraft is very complex, it is a permanent subject to study the variable pitch control device of the propeller so that it can control the blade angle more accurately and achieve the best output efficiency of the propeller. Therefore, the working propeller blade angle It is necessary to implement monitoring and collect the blade angle in time to study the relationship between blade angle, propeller speed and engine power, and then to study a better propeller pitch control device, but the current propellers cannot be measured in real time and Timely feedback of the angle of its blades

Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0011] Such as figure 1 and figure 2 As shown, this embodiment includes a driving gear 11, a driven gear 4, a support 6, an angle sensor 5, an end face conductive ring 8, an end face brush box 9, an end face brush box support 10, a processor and a display screen. The driving gear 11 is composed of two halves that can be combined into a full circle, and the two halves are clamped on the root 1 of the blade, and are fixed together by bolts 12, flat washers 13 and nuts 14; the driving gear 11 has only 1 / There are teeth on the 4 circumference, and the teeth on the 1 / 4 circumference can ensure that the blades are always meshed with the teeth on the driven gear 4 when the angle of the blade is changed to the maximum range. The support 6 is fixed on the side wall of the propeller shell 7 by bolts, and the angle sensor 5 is fixed on the support 6 b...

The invention discloses a propeller blade angle monitoring implementation device. A driving gear is coaxially and fixedly arranged on a propeller root of a propeller blade, an angle sensor is fixedly arranged on a support seat arranged on the side wall of a propeller case of a screw propeller, a driven gear is fixedly arranged on a shaft of the angle sensor, the driven gear is engaged with the driving gear, an end surface brush box is fixedly arranged on an engine casing through an end surface brush box support frame, an end surface conducting ring is fixedly arranged on the side wall of the propeller casing, a carbon brush arranged on the end surface brush box is tightly pressed on the end surface conducting ring, the information output end of the angle sensor is fixedly arranged on the end surface conducing ring through a conducting wire, the end surface brush box is connected with the signal input end of a processor arranged in a cab through a conducing wire, and the signal output end of the processor is connected with a display screen. The propeller blade angle monitoring implementation device has the advantages that the propeller blade angle can be measured at any time and can be fed back in time, the structure is simple and reliable, the mounting and the dismounting are convenient, the propeller blade angle measurement is precise, and the on-site maintenance replacement can be realized.
Description
technical field [0001] The invention relates to an implementation monitoring device for propeller blade angle. Background technique [0002] The propeller pitch control device is to control the propeller to work at the best blade angle under various working conditions of the engine and the aircraft, so as to achieve the best working efficiency of the propeller. Because the flight environment of the aircraft is very complicated, it is a permanent subject to study the variable pitch control device of the propeller so that it can control the blade angle more accurately and achieve the best output efficiency of the propeller. Therefore, the working propeller blade angle It is necessary to implement monitoring and collect the blade angle in time so as to study the relationship between the blade angle and the propeller speed and engine power. It is necessary to study a better propeller pitch control device, but the current propellers cannot be measured in real time and Feedback t...
