Problems solved by technology

However, the traditional off-line detection of periodic sampling of lubricating oil has certain limitations: poor real-time performance, small amount of accumulated data, and high sampling requirements; especially the sampling of lubricating oil in offshore wind turbine equipment requires a lot of manpower and material resources
[0004] However, the existing related patents mainly focus on the online monitoring of lubricating oil, including hardware selection and connection, and data detection and acquisition. There is no solution to the problem of taking corresponding control measures in linkage with the maintenance mechanism. In order to solve the above problems, the present invention provides an online monitoring device, monitoring method and system for the lubricating oil of the gearbox of a wind turbine

Abstract

The invention provides an online monitoring device, monitoring method and system for lubricating oil of a gearbox of a wind turbine generator. The device comprises a lubricating oil monitoring bypass, an online monitoring device, a data transmission and control module, a cloud server and a client. The lubricating oil monitoring bypass is connected to a main oil way of a gearbox outlet in parallel, lubricating oil is led out from the main oil way, when the lubricating oil flows through the online monitoring device, real-time data of various parameters of oil liquid are comprehensively collected and sent to the data transmission and control module, then the data are uploaded to the cloud server through wireless communication setting on the module, after the client obtains the monitoring data, the monitoring data are comprehensively processed and analyzed through a system software program according to compensation parameters obtained through an early-stage experiment, effective monitoring of the quality of the lubricating oil is achieved, a certain basis is provided for follow-up control measures and fault diagnosis, and basic maintenance, regulation and control operation is achieved through the data transmission and control module. According to the device, the method and the system, the requirement of off-line detection is met, and the defect of off-line detection is overcome.

Description

technical field [0001] The invention belongs to the technical field of state monitoring and intelligent control of wind turbines, and relates to an online monitoring device, method and system for lubricating oil in a gearbox of a wind turbine. Background technique [0002] In wind turbines, the gearbox is an important part that affects the operation and maintenance life and safety of the entire unit. Wind turbines are often erected in places with harsh natural environments, and the wind force has various uncontrollability, so that the wind turbines are often in a state of uneven stress and size, as well as extreme weather such as storms, blizzards, and strong typhoons, as well as temperature differences between day and night. Due to the influence of factors such as large ones, gearbox failures frequently occur, but equipment installation and maintenance work is difficult to carry out, and the corresponding costs are also high. If the gearbox fails, it will affect the entire...
