Description

Technical Field

[0001] The invention relates to the technical field of wind turbine generators, and in particular to a device and a method for cleaning a bearing of a wind turbine generator. Background Art

[0002] Wind turbines are electrical equipment that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Wind turbines are generally composed of wind rotors, generators, direction regulators, towers, speed limit safety mechanisms, and energy storage devices. Nowadays, wind turbines are mainly used in mountainous areas and at sea. When wind turbines are running for a long time, the internal bearings need to be cleaned.

[0003] Since rainwater at sea is salty water and contains a large amount of dissolved salts, the salt and other minerals in the salty water can react electrochemically with the bearing material, causing corrosion on the bearing surface. This corrosion may cause spots, grooves or peeling on the bearing surface, affecting the performance and service life of the bearing. When the existing offshore wind turbines are maintaining and cleaning the bearings, they do not have the function of detecting the degree of electrochemical corrosion on both sides of the bearings, which can easily lead to the continued use of severely corroded bearings, affecting the working efficiency of the wind turbines.

[0008] A method for using a wind turbine bearing cleaning device comprises the following steps:

[0009] S1: When the center shaft rotates, it can drive the synchronous plate to rotate at the same time. When the synchronous plate rotates, it can drive the slide bar to rotate. When the slide bar rotates, the trigger switch can be activated to stop the motor from rotating. At the same time, the electric rod is started to drive the swing plate to swing downward, so that the swing plate fits the slot of the limit wheel. At this time, the center shaft is in a non-rotatable state, which is convenient for the staff to replace the new bearing;

[0010] S2: When the rotating plate drives the bearing to move to the front side of the mounting plate, the detection motor starts, and the detection motor can drive the rotating plate to rotate through the power output shaft, and the rotating plate can drive the guide rod to rotate along the inner cavity of the threaded opening, and the movement trajectory of the guide rod can be limited by the setting of the slider and the first spring. When the guide rod rotates and moves, it can fit the outer side of the bearing. When the surface of the bearing is electrochemically corroded, there are dents on the surface of the bearing. When the guide rod contacts the dents on the surface of the bearing, it can move back and forth. When the guide rod moves to the rear side, it can contact the travel switch. When the travel switch is activated, it can trigger the electric telescopic rod. When the electric telescopic rod is started, it can push the pressing rod to move to the rear side. When the pressing rod moves to the rear side, it can drive several fitting rods to move backward. When the locking rod moves to the side, it can fit with the guide groove when it wants to move to the rear side, thereby driving the sleeve to rotate. When the sleeve rotates, it can drive several second meshing blocks to rotate. When the second meshing block rotates, it fits with the collision rod at the rear side, thereby driving the annular plate at the rear side to rotate. When the annular plate at the rear side rotates without driving the annular plate at the front side through the adjacent synchronous rod, it can be judged that the current electrochemical corrosion of the bearing is relatively light. At the same time, when the annular plate at the rear side rotates and drives the adjacent synchronous rod to rotate, it can drive the movable ring at the rear side to rotate. The movable ring at the rear side can drive the threaded sleeve at the rear side to rotate, thereby driving the adjacent screw rod to rotate. When the screw rod at the rear side rotates, the trigger at the rear side can be activated. The trigger at the rear side can start the motor to rotate the current bearing.

[0011] S3: When the motor is started again, the motor power output shaft can drive the synchronous plate and the rotating plate to rotate synchronously. When the synchronous plate rotates, it can drive the sliding rod to rotate. When the sliding rod rotates, the trigger switch can be activated to stop the motor from rotating. At this time, the rotating plate rotates ninety degrees again, and the bearing that needs to be cleaned moves between the two cleaning brushes. At the same time, the cleaning motor is started, and the cleaning brush on the right side can be driven to rotate through the power output shaft. While the power output shaft rotates, the adjusting rod can be driven to rotate through the first groove wheel and the first belt. The adjusting rod can drive the second groove wheel on the rear side to rotate. The second groove wheel on the rear side can drive the second groove wheel on the front side to rotate through the second belt. The second groove wheel on the front side can drive the rear rod to rotate. The rear rod can drive the cleaning brush on the left side to rotate. When the two cleaning brushes rotate synchronously, the bearing can be cleaned.

[0012] S4: When the synchronous rod located on the rear side rotates and drives the annular plate located on the front side to rotate through the movable column, it can be determined that the current electrochemical corrosion of the bearing is severe, and the annular plate located on the front side can drive the movable ring located on the front side to rotate through the synchronous rod located on the front side, and the movable ring located on the front side can drive the threaded sleeve located on the front side to rotate, and the threaded sleeve located on the front side can drive the trigger located on the front side to start by engaging with the adjacent screw rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention can achieve the purpose of comprehensive detection of the bearing surface from the outside to the inside by fitting the threaded opening on the surface of the mounting plate with the guide rod, thereby avoiding the situation where electrochemical corrosion occurs on the bearing surface but is not detected. When the bearing surface detection is completed, it can be determined whether the current bearing should be cleaned or scrapped according to the severity of the corrosion on the bearing surface. If it is determined that the current electrochemical corrosion degree of the bearing is relatively light, the bearing is moved between two cleaning brushes for cleaning. If it is determined that the current electrochemical corrosion degree of the bearing is relatively heavy, the cylinder is started to directly move the bearing out, thereby avoiding the scrapped bearing from being continued to be used on the wind turbine.

[0034] A method for using a wind turbine bearing cleaning device comprises the following steps:

[0035] S1: When the central shaft rotates, the synchronous plate 15 can be driven to rotate at the same time. When the synchronous plate 15 rotates, the slide bar can be driven to rotate. When the slide bar rotates, the trigger switch 27 can be activated to stop the motor 12 from rotating.

At this time, the central shaft is in a non-rotatable state, which is convenient for the staff to replace the new bearing 16;

[0036] S2: When the rotating plate 8 drives the bearing 16 to move to the front side of the mounting plate 38, the detection motor 36 is started, and the detection motor 36 can drive the rotating plate 32 to rotate through the power output shaft, and the rotating plate 32 can drive the guide rod 39 to rotate along the inner cavity of the threaded opening.
