Wind turbine generator fault intelligent monitoring system

Abstract

The invention discloses a wind turbine generator fault intelligent monitoring system, and relates to the technical field of wind turbine generator safety. The wind turbine generator fault intelligent monitoring system comprises a pipeline, a robot, a server and a traction pull-back device, wherein the pipeline is transparent, is designed and arranged according to an internal structure of a generator cabin, the pipeline is provided with a plurality of site positioning sheets, the robot is internally provided with a site acquisition card, one or more of a visual sensor, a sound sensor, a temperature and humidity sensor or a combustible gas sensor is / are arranged at the front end of the robot, the robot is in communication connection with the server, and the traction pull-back device is arranged at a port of the pipeline and is connected to the tail end of the robot through a steel wire rope. The wind turbine generator fault intelligent monitoring system has the advantages that the inspection height is not limited, the system is not blocked by inspection path obstacles, positioning is accurate, the monitoring range is wide, safety and reliability are achieved, and monitoring data collection and analysis are complete.

Description

technical field [0001] The invention relates to the technical field of wind turbine safety, in particular to an intelligent fault monitoring system for wind turbines. Background technique [0002] Robots are commonly used for fault monitoring of wind turbines, most of which are equipped with required sensors in the form of crawler vehicles for monitoring. Because the space environment where wind turbines are located is quite complex, there are many problems in the fault monitoring of crawler robots, as follows. [0003] 1. Inspection height problem: Affected by the particularity of the wind turbine cabin environment, the vertical height of the general inspection components is about 1.6m, and most of the crawler robots available in wind turbines cannot be monitored in practical applications. [0004] 2. Obstacles in the actual inspection path: Most of the wind turbine cabins are relatively compact and have very limited space. Many parts of them are equipped with hoisting or i...

AI Technical Summary

Problems solved by technology

[0003] 1. Inspection height problem: Affected by the particularity of the wind turbine cabin environment, the vertical height of the general inspection components is about 1.6m, and most of the tracked robots available in wind turbines cannot be monitored in actual applications.

[0004] 2. Obstacles in the actual inspection path: Most of the wind turbine cabins are relatively compact and have very limited space. Many parts of them are equipped with hoisting or installation parts. Difficult, or even impossible to complete a comprehensive inspection

[0005] 3. Communication problems: There are few free points in the current wind turbine cabin, and most crawler robots use independent communication and independent transmission. Due to the small number of points and independent communication, the feedback information cannot truly reflect the current status of the feedback wind turbine

[0006] 4. The problem of monitoring range: Due to the special structure of the nacelle in the wind turbine, many places will be blocked, resulting in incomplete monitoring; affected by the height of the unit equipment, the current crawler robot cannot realize overlooking monitoring, and cannot shoot overlooking and surrounding visual effects pictures or animations of

[0008] 6. Incompleteness and lack of monitoring data collection and analysis: The inspection system needs to monitor the wind turbines for 24 hours, so as to provide daily warning, analysis, collection and storage of various unsafe factors or problematic components of the wind turbines For functions such as comparison and comparison, it should be linked and coordinated with the data of wind turbines. The existing crawler robots or inspection systems cannot achieve this goal.
