Real-time measuring device for propeller blade angles

Abstract

The invention discloses a propeller blade angle real-time measuring device. The device comprises a base, a fixed plate is arranged at the top of the base, a clamping groove is formed in the fixed plate, and a propeller is clamped to the fixed plate through the clamping groove. Through the arrangement of the clamping block at the bottom of the propeller, the propeller can be placed in the clampinggroove, the clamping block extrudes the clamping head, and when the clamping head reaches the bottom of the clamping groove, the clamping head is tightly clamped in the clamping groove through the elastic force of the clamping spring, so that the propeller is fixed, and the situation of inaccurate measurement during measurement is avoided; according to the propeller angle measuring device, the angles of blades of a propeller can be accurately measured, a worker can conveniently use the corresponding propeller at the accurate angle, a sliding rod is arranged at the bottom of the fixed plate, the sliding rod can slide in a sliding groove, and therefore the blades are driven to move to a detected place to measure the angles of the blades; and the condition that errors are easy to occur in manual measurement is avoided.

Description

technical field [0001] The invention relates to a propeller, in particular to a real-time measuring device for the blade angle of the propeller. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to a helical surface. A kind of propeller. There are many types of propellers, which are widely used, such as propellers of aircraft and ships. [0003] The blade angle, also known as the twist angle of the blade, refers to the angle between the propeller chord line and the propeller rotation plane. It changes with the radius, and its change rule is the most important factor affecting the performance of the propeller. [0004] In the existing technology, the measurement of the angle of the blade of the propeller is generally carried out manually with ...

Problems solved by technology

[0004] In the existing technology, the measurement of the angle of the blade of the propeller is generally carried out manually with an angle ruler. This method of measurement will consume a lot of energy of the workers, and it is prone to inaccurate measurement, which may affect Improper use of the propeller due to inaccurate use of the subsequent propeller
