Blade detector of adjustable-pitch propeller

Abstract

The invention discloses a blade detector of a adjustable-pitch propeller. The blade detector of the adjustable-pitch propeller comprises a main body, a hydraulic cylinder and a detecting mechanism, clamping blocks are respectively welded to the outer walls of the left side and the right side of the main body, one ends of the clamping blocks are connected with connecting rods, movable cylinders aremounted at one ends of the connecting rods, the connecting rods and the movable cylinders are tightly fastened through nuts, plugs are connected to the upper parts of the movable cylinders, the hydraulic cylinder is mounted on the inner wall of the bottom of the main body, hydraulic rods are arranged on the hydraulic cylinder, and a pushing plate is fixed to the upper part of the hydraulic rods.The blade detector of the adjustable-pitch propeller is provided with a first movable gear, the first movable gear is driven to drive rotating blades on a second movable gear to rotate by rotating a hand wheel, meanwhile the rotating blades are movably connected with a round groove through a movable wheel, thus the angle formed by the rotating blades and a rotary shaft can be simply and conveniently changed according to the requirements of people, detection of the detecting mechanism is further more accurate, and usage is more convenient.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an adjustable-pitch propeller blade detector. Background technique [0002] Adjustable pitch propeller, also known as "adjustable pitch propeller", refers to the "propeller" that rotates the propeller blade through the built-in mechanism of the propeller hub to change the angle between the propeller hub and the propeller hub to adjust the pitch to adapt to various working conditions. Adjustable pitch propellers are widely used, mainly in petrochemical industry, electric power industry, aviation shipbuilding industry, paper industry, textile industry, metallurgical industry, etc. [0003] The angle adjustment of the propeller blades on the market is cumbersome and troublesome in the process of using the detectors on the market, which consumes a lot of time when people need to adjust. At the same time, the general detectors do not have certain protection devices, which makes them...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an adjustable-pitch propeller blade detector to solve the problem that the adjustment of the angle of the propeller blade in the use of the detector proposed in the above-mentioned background technology is relatively cumbersome, and the steps are relatively troublesome, so that people need to consume a lot of time when adjusting. At the same time, the general detector does not have a certain protection device, which makes it vulnerable to collision damage
