Description

Technical Field

[0001] The invention relates to a training platform, in particular to a lubrication training platform for a wind turbine generator set. Background Art

[0002] Wind is one of the pollution-free energy sources. And it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that lack water, fuel and have inconvenient transportation, it is very suitable to use wind power generation according to local conditions, and there is a lot of potential. Wind power generation is to convert the kinetic energy of wind into mechanical kinetic energy, and then convert mechanical energy into electrical kinetic energy. The device required for wind power generation is called a wind turbine. The operation and maintenance of wind turbines has received increasing attention. As one of the key links in the operation of equipment, lubrication management plays an important role in ensuring the safe operation of wind turbines. The lubrication system of a general wind turbine can be divided into three parts: the main shaft lubrication system, the yaw lubrication system and the pitch lubrication system. At present, the teaching of maintaining the lubrication system at the wind power operation and maintenance site is insufficient. At present, the lubrication problems of the pitch system, yaw system and main shaft bearing of wind turbines are becoming increasingly serious, and wind power workers lack effective lubrication system training. Summary of the invention

[0003] The present invention aims to provide a wind turbine lubrication training platform, which can be used to provide on-site operation and maintenance personnel with manual lubrication training for pitch bearings and pitch gears, manual lubrication training for yaw bearings and yaw gears, manual lubrication training for main shaft bearings, and automatic lubrication training for various modules.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A wind turbine generator set lubrication training platform, comprising: a training operation platform, a yaw system lubrication module fixed on the training operation platform, a main shaft system lubrication module fixed on the training operation platform, a pitch system lubrication module fixed at one end of the main shaft system lubrication module, and an automatic lubrication system fixed on the training operation platform;

[0006] The automatic lubrication system includes an automatic lubrication pump fixed on a training operation platform, a lubricating oil box fixed on the automatic lubrication pump, a filter connected to the automatic lubrication pump through a pipeline, a safety valve connected to the filter through a pipeline, a primary distributor connected to the safety valve through a pipeline, a secondary distributor connected to the primary distributor through a pipeline, and a lubricating pinion connected to the secondary distributor through a pipeline; the lubricating pinion is meshed with the inner rings of the yaw bearing and the pitch bearing.

[0007] Furthermore, the automatic lubrication system includes an automatic lubrication pump fixed on the training operation platform, a lubricating oil box fixed on the automatic lubrication pump, a filter connected to the automatic lubrication pump through a pipeline, a safety valve connected to the filter through a pipeline, a first-level distributor connected to the safety valve through a pipeline, and a lubricating pinion connected to the first-level distributor through a pipeline; the lubricating pinion meshes with the inner ring of the yaw bearing and the pitch bearing.

[0008] Furthermore, the pitch system lubrication module includes a pitch bearing fixed on the housing, a manual lubrication point fixed on the pitch bearing, a pitch pinion meshing with the pitch bearing, a pitch reducer connected to the pitch pinion via an output shaft, and a pitch drive motor fixedly connected to the housing.

[0009] Furthermore, the pitch drive motor is fixed on the housing, and the pitch bearing is an internal gear slewing bearing.

[0010] Furthermore, the yaw system lubrication module includes a yaw drive motor fixed on the training operation platform, a yaw reducer connected to the yaw drive motor through an output shaft, a yaw pinion connected to the yaw reducer through an output shaft, a yaw bearing meshing with the yaw pinion, and a lubrication point fixedly connected to the yaw bearing; the yaw bearing is a slewing bearing.

[0011] Furthermore, the spindle system lubrication module includes a bearing seat fixed on the training operation platform, a spindle bearing fixedly connected to the bearing seat, a lubrication point fixedly connected to the bearing seat, and a spindle fixedly connected to the spindle bearing.

[0012] Furthermore, the training operation platform includes a supporting platform, an operating platform fixed on the supporting platform, and a tool platform fixed on the supporting platform.

[0013] The beneficial effects achieved by the present invention are as follows:

[0014] The present invention simulates the actual variable pitch system, yaw system, and main shaft bearing of a wind turbine, and produces a training operation platform that can reproduce the manual / automatic lubrication operation of the variable pitch system, yaw system, and main shaft bearing of the wind turbine. The platform can simulate the automatic lubrication system of an offshore wind turbine and the automatic lubrication system of an onshore wind turbine. When the automatic lubrication system is working, the lubricating oil is transported into the primary distributor, where the lubricating oil is distributed to the secondary distributor in a suitable proportion, and then the secondary distributor supplies the lubricating oil to the lubrication point in a suitable proportion. The control mode and time interval can be set by the user. Manual lubrication is mainly based on the lubrication maintenance and regular inspection procedures of the variable pitch system, yaw system, and main shaft system of the wind turbine. The user holds a grease gun and pours lubricating grease into the bearing according to the operating procedures.

[0015] The present invention has a lubrication status demonstration function, that is, the operation of each module mechanism is controlled by the operating user through the operating console. The operator can visually observe the lubrication conditions of the variable pitch bearing and its internal gear meshing area, the yaw bearing and its external gear meshing area, and the main shaft bearing before and after lubrication maintenance, so as to ensure that the user can make a correct judgment on the lubrication status of the variable pitch actuator, yaw actuator, main shaft system and other components.
