Embodiment Construction

[0040] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0041] The invention is aimed at a three-blade fan, and implements fault diagnosis of the blade based on blade vibration monitoring, and proposes a vibration-based multi-dimensional fan blade self-diagnosis device and method. The device consists of figure 1 As shown, the blade vibration collector synchronously collects the vibration signals of blade vibration sensor 1, blade vibration sensor 2, and blade vibration sensor 3: and transmits the vibration signals to the ring network switch through the wireless communicator, and finally deploys data analysis software on the server to analyze and Store vibration data. Among them, the three blade vibration sensors are all installed at a distance of 1 / 3 of the total length...

Abstract

The present invention relates to a multi-dimensional fan blade self-diagnosis device and method based on vibration. The device includes: a first blade vibration sensor, a second blade vibration sensor and a third blade vibration sensor, respectively used to detect the vibration of three fan blades signal; the blade vibration collector is used to synchronously collect the vibration signals detected by the first blade vibration sensor, the second blade vibration sensor and the third blade vibration sensor and send them to the server through a communication device; the server is used to receive The received vibration signals are stored and analyzed. According to the collected vibration data of the fan blades, the invention analyzes the stress of the blades, so as to study the fault types of the blades, and guide the on-site engineering personnel to maintain the fan blades in a planned way. The power supply and signal transmission are simple, easy to implement, and low in cost. .

Description

technical field [0001] The invention relates to the field of equipment monitoring, in particular to a vibration-based multi-dimensional fan blade self-diagnosis device and method. Background technique [0002] At present, the three-blade fan is the mainstream model. Blades are one of the key components of wind turbines, and their condition directly affects the power generation efficiency of wind turbines. The blades work at high altitude and under all-weather conditions, and are often attacked by air medium, atmospheric rays, sand dust, lightning, heavy rain, ice and snow, which may easily cause damage to the blades. The traditional way of relying on manual inspection to find blade problems is not only time-consuming and labor-intensive, but also inefficient. It is often impossible to find potential problems and abnormal defects of blades in time, which will have a huge impact on the operation and maintenance of wind turbines, and even lead to safety accidents. [0003] In...
