Description

Technical Field

[0001] The utility model relates to the technical field of wind power gear box monitoring, and more specifically, to a fault monitoring device for a wind power gear box. Background Art

[0002] The gearbox in a wind turbine is an important mechanical component. Its main function is to transmit the power generated by the wind rotor under the action of wind to the generator and make it obtain the corresponding speed. Some faults will occur inside the wind turbine gearbox during long-term use. In order to ensure the stable operation of the wind turbine gearbox, it is necessary to regularly monitor the faults of the wind turbine gearbox.

[0003] At present, due to the sealing of the internal structure of the gearbox, it is difficult to detect its internal faults in time during daily inspections, and frequent removal of the gearbox observation hole cover or plug is time-consuming and labor-intensive, which will affect its sealing, causing oil leakage or contamination of the gearbox oil.

[0004] After searching, the Chinese patent with authorization announcement number CN220979766U discloses an online monitoring device for the gearbox of a wind turbine group. Without destroying the overall structure of the gearbox, several image sensors can be installed on the gearbox, and the image can be transmitted back to the user terminal through the image transmission module. The internal operating status of the gearbox can be monitored in real time at the user terminal, and faults and abnormal conditions can be warned through image analysis.

[0005] However, when this structure is actually used, since common fault types of wind turbine gearboxes include bearing wear, gear breakage, oil contamination, etc., it is necessary to determine that the monitored parameters are vibration, temperature, oil quality, etc., and the image sensor used in this structure can only collect the conditions inside the gearbox, while the vibration conditions of the bearings and gear meshing inside the gearbox, the temperature conditions inside the gearbox, and the oil conditions are difficult to monitor, resulting in an inability to comprehensively judge the fault conditions inside the gearbox and a low monitoring range. In view of this, the utility model proposes a fault monitoring device for a wind turbine gearbox. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a fault monitoring device for a wind turbine gearbox to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fault monitoring device for a wind turbine gearbox, comprising a detection box, a box cover is hingedly connected to the surface of the detection box, a display device is embedded and installed inside the box cover, an image sensor is installed inside the detection box, a vibration sensor is arranged at the bottom of the image sensor, a temperature sensor is arranged at the bottom of the vibration sensor, an oil monitoring sensor is arranged at the bottom of the temperature sensor, the image sensor, vibration sensor, temperature sensor and oil monitoring sensor are all electrically connected to a data processing module, and the data processing module is connected to the display device by wires.

[0008] It can be seen that in the above structure, the image sensor, vibration sensor, temperature sensor and oil monitoring sensor respectively monitor the fault condition of the gearbox, and display the monitored data through the display device, thereby facilitating the operator to accurately understand whether the gearbox is faulty or not.

[0009] In order to facilitate the reasonable placement and storage of each sensor, preferably, a plurality of placement slots are opened inside the detection box, and the image sensor, vibration sensor, temperature sensor and oil monitoring sensor are all placed in the corresponding placement slots.

[0010] In order to facilitate opening and closing of the box cover and to facilitate carrying of the entire device, preferably, the surfaces of the detection box and the box cover are respectively provided with buckles and blocks, the detection box and the box cover are connected by the buckles and blocks, and the surfaces of the detection box and the box cover are both provided with handles.

[0011] In order to facilitate the cleaning of dust on the surface of the display device and facilitate operators to accurately view the display data, preferably, the surface of the box cover is provided with installation grooves on both sides of the display device, and sliding rods are provided inside the two installation grooves. A movable plate is provided inside the box cover, and cleaning cotton is provided on the back of the movable plate. A slider is provided outside the sliding rod, and the slider is installed on the outside of the sliding rod and slidably connected to the outside of the sliding rod. The slider is fixedly installed on the bottom of the movable plate, and the cleaning cotton is attached to the surface of the display device.

[0012] Technical effects and advantages of the utility model:

[0013] 1. Image sensors are installed at various locations inside the wind turbine gearbox to capture images of the internal conditions of the wind turbine gearbox. Vibration sensors are installed at the bearings and gear meshing locations of the gearbox to collect vibration data in real time. Temperature sensors are installed inside the gearbox to monitor temperature changes inside the gearbox to determine whether there is overheating. Oil monitoring sensors are installed at the oil position of the gearbox to monitor the temperature, viscosity, moisture content, and contaminant concentration of the oil to evaluate the oil quality. The data from the above sensors are integrated and displayed through a display device, so that operators can monitor and handle gearbox faults without destroying the overall structure of the gearbox.

[0014] 2. By continuously sliding the movable plate, the slider at the bottom of the movable plate slides and guides on the outside of the slide rod. The movable plate drives the cleaning cotton to adhere to the surface of the display screen for cleaning, thereby improving the cleanliness of the display device and making it easier for operators to view data accurately.
