Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically to a wind turbine bearing operation monitoring device. Background Technology

[0002] Common defects in the appearance of the rotating gap of wind turbine bearings, such as main shaft bearings, include: mechanical wear: surface fatigue, spalling, and cracks;

[0003] Lubrication issues include oil film failure, contamination, and oil leakage, as well as oil sludge being squeezed out of the bearing's rotational joints due to abnormal bearing rotation. These problems are undetectable by sensors that monitor vibration, temperature, and other data. If this squeezed-out oil sludge is not cleaned promptly, it can easily contaminate other components of the bearing equipment and may even cause fire due to localized high temperatures. For example, application number "201620739957.2" highlights the difficulty of installing monitoring equipment due to the limited space in the bearing monitoring area and the need for drilling. Furthermore, it prevents users from viewing the monitoring footage of each monitoring point at any time via a smart terminal.

[0004] Therefore, a wind turbine bearing operation monitoring device is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a wind turbine bearing operation monitoring device. This utility model adjusts the rotation angle of the first connecting arm in the vertical direction by rotating the first rotating shaft, and then rotates the second connecting arm in the horizontal direction by rotating the second rotating shaft. Furthermore, the installation angle of the first base plate in various directions can be adjusted by rotating the abutting ball in the rotating seat. In addition, this utility model uses magnetic plates for both the first and second base plates, which can be adsorbed onto the iron plate around the wind turbine bearing without drilling, making installation and angle adjustment convenient and quick.

[0006] Then, by adjusting the fourth rotating shaft, the aiming angle of the camera is adjusted, and the image monitored by the camera is transmitted to the monitoring terminal through the wireless data transmission unit to monitor whether the bearing seal is leaking oil or seeping oil; check whether there are cracks, corrosion or foreign objects intruding on the bearing surface; observe whether the lubrication system (such as oil pipes and oil pumps) is working properly. Then, the staff connects to the server through the smart terminal to view the status of the corresponding monitored parts. The operation is simple, convenient and fast, and this utility model has strong practicality.

[0007] This utility model is implemented as follows:

[0008] A wind turbine bearing operation monitoring device includes a U-shaped support frame. First rotating shafts are provided on both side walls of the U-shaped support frame, and first connecting arms are rotatably connected to the first rotating shafts. Second rotating shafts are connected to the first connecting arms, and second connecting arms are rotatably connected to the second connecting arms. A first base plate is rotatably connected to the bottom end of the second connecting arms. A vertical support arm is fixedly connected to the front end of the U-shaped support frame, and a third rotating shaft is provided at the bottom end of the vertical support arm, through which a second base plate is rotatably connected.

[0009] A crossbar is fixed in the middle of the "U"-shaped support frame. A fourth rotating shaft is located at the lower end of the crossbar, through which a camera is rotatably connected. A control device is located above the camera. The control device includes a housing, within which a control processing unit is fixed. A storage unit is also connected to the control processing unit. The control processing unit is an Arm 7 type control processing unit.

[0010] The camera is connected to the control processing unit, which is also connected to a wireless data transmission unit. The wireless data transmission unit uses a 4G communication unit and is connected to a monitoring terminal. The monitoring terminal includes a server connected to the wireless data transmission unit, which is connected to a PC and a smart terminal via wireless connection.

[0011] Furthermore, both the first base plate and the second base plate are magnetic plates. The first base plate is provided with a hollow rotating seat, and an abutting ball is provided at the bottom end of the second connecting arm. The abutting ball is embedded in the rotating seat and abuts against the inner wall of the rotating seat.

[0012] Furthermore, the first rotating shaft is a vertically rotating shaft, and the second rotating shaft is a horizontally rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the first base plate and the second base plate are both made of magnetic plates, which can be adsorbed onto the iron plate around the bearing of the wind turbine, without drilling, and the installation and adjustment angle are convenient and quick.

[0014] Then, by adjusting the fourth rotating shaft, the aiming angle of the camera is adjusted, and the image monitored by the camera is transmitted to the monitoring terminal through the wireless data transmission unit to monitor whether the bearing seal is leaking oil or seeping oil; check whether there are cracks, corrosion or foreign objects intruding on the bearing surface; observe whether the lubrication system (such as oil pipes and oil pumps) is working properly. Then, the staff connects to the server through the smart terminal to view the status of the corresponding monitored parts. The operation is simple, convenient and fast, and this utility model has strong practicality. Attached Figure Description
