Portable point inspection recording instrument for wind turbine generator

Abstract

The invention discloses a portable point inspection recording instrument for a wind turbine generator in the technical field of routing inspection for operation of wind turbine generators. The portable point inspection recording instrument is mainly composed of a CPU control module, a power module, a storage module, a communication module, an input and output module, an A / D conversion module, a data collecting module and a point inspection information management module. Besides a function of collecting and analyzing traditional data such as temperatures and vibration, functions of image collecting, audio collecting and the like are added, point inspection information can be fully digitalized, and meanwhile a wired and wireless communication function is achieved; the portable point inspection recording instrument further has a maintenance instructing function, technical data such as circuit diagrams, technical parameters and service handbooks of the wind turbine generator can be stored, instructions from a wind power plant control center can be received in real time, some emergency problems can be conveniently solved by point inspection personnel, and intelligence and integration of point inspection and maintenance are achieved.

Description

technical field [0001] The invention belongs to the technical field of wind turbine operation patrol inspection, and specifically relates to a portable spot inspection recorder for wind turbines. Background technique [0002] Wind energy is an environmentally friendly, green, and renewable energy. It is universal, cheap, and clean, making it known as the most potential energy in renewable energy. Wind energy development has become one of the most commercially valuable projects in new energy. At present, the construction scale of wind farms in China is gradually expanding. In the past 10 years, the installed capacity of wind power in China has increased by 158 times, far higher than the global average growth of 8 times, and the growth rate ranks first in the world. At the same time, the total domestic wind power generation exceeded 100 billion kWh in advance last year, and the power generation capacity has surpassed nuclear power, becoming the third largest source of electri...

Problems solved by technology

[0003] The point inspection mode currently implemented in thermal power plants, through practice and application in wind farms, has found many problems, is not practical, and cannot meet the requirements of equipment maintenance management

The main manifestations are: the operating environment of the wind farm is relatively special, the number of equipment is large, and the operating area is large, resulting in difficulties in equipment management, which can easily lead to over-maintenance and under-maintenance of equipment

First, no matter what the operating status of the equipment is, it is necessary to carry out regular spot checks, which may easily lead to "over-maintenance" or "under-maintenance" of the equipment, increasing maintenance costs

The second is that the scale of wind farms is relatively large, most of which are located in high mountains and Gobi, and a large number of maintenance personnel are required for regular inspections. Due to the influence of insufficient technical level and equipment performance, the quality of regular inspections will not be high.

The third is that in the regular inspection of wind turbines, there are many quantities that cannot be directly measured by equipment, such as whether there are oil stains and corrosion on the inner and outer walls of the tower, which requires more comprehensive functions of the spot inspection instrument, such as image acquisition and vibration analysis.
