Description

Technical Field

[0001] This invention relates to the field of gearbox vibration detection technology, specifically a gearbox vibration detection device for wind turbines. Background Technology

[0002] As the global energy structure shifts towards clean energy, wind power, as a mature and efficient renewable energy source, continues to increase its share in the energy supply system. Wind turbines operate in complex outdoor environments for extended periods, enduring strong winds, temperature fluctuations, dust storms, and other external factors. The gearbox, as the core transmission component of the wind turbine, plays a crucial role in converting the rotational kinetic energy of the wind turbine into the high-speed mechanical energy required by the generator. Its operating status directly determines the power generation efficiency and safety stability of the wind turbine. Because the gearbox contains precision transmission components such as gears and bearings, it is prone to abnormal vibrations due to wear, fatigue, and assembly deviations during long-term high-load operation. Failure to detect and address these issues promptly can lead to gearbox failure, resulting in wind turbine shutdown and significant economic losses. Therefore, a wind turbine gearbox vibration detection device is needed. Currently available gearbox vibration testing devices often suffer from poor gearbox clamping stability and low pressure signal acquisition accuracy during testing. Furthermore, some devices are complex to operate and require a high level of expertise from operators, which affects the reliability of the testing results. Summary of the Invention

[0003] The purpose of this invention is to provide a vibration detection device for wind turbine gearboxes, addressing the problems mentioned in the background art regarding existing gearbox vibration detection devices, such as poor gearbox clamping stability, low pressure signal acquisition accuracy, complex operation, and high requirements for operator expertise, which consequently affect the reliability of detection results. To achieve the above objective, this invention provides the following technical solution: a vibration detection device for wind turbine gearboxes, comprising a device base plate; The detection component includes a fitted bottom frame disposed above the device base plate. An electric telescopic rod is fixedly connected to the top of the fitted bottom frame. A splicing piece is fixedly connected to the top of the electric telescopic rod. A detection upper frame is disposed above the splicing piece. An upper pressure sensing plate is disposed below the detection upper frame. A detection lower frame is fixedly connected to the top of the device base plate. A lower pressure sensing plate is disposed above the detection lower frame. The auxiliary components include a control console, which is fixedly connected to the top of the device base plate. A connecting wire is fixedly connected to one side of the detection frame, and the other end of the connecting wire is installed on one side of the control console.

[0004] More preferably, the detection component is positioned above the device base plate, the auxiliary component is positioned above the device base plate, and the bottom of the detection upper frame has a splicing hole. The splicing piece is internally threaded with a splicing bolt. By installing the detection component, when vibration detection of the wind turbine gearbox is required, the gearbox is first placed on the lower pressure sensing plate above the detection lower frame. Then, the electric telescopic rod is activated via the control console. The electric telescopic rod will drive the splicing piece and the detection upper frame connected to the splicing piece to move downward, so that the upper pressure sensing plate below the detection upper frame gradually approaches and fits against the top of the gearbox. During this process, the upper and lower pressure sensing plates will sense the pressure applied to the gearbox in real time and transmit the pressure signal through the relevant transmission structure. At the same time, the splicing bolt can fix the relative position of the splicing piece and the detection upper frame, ensuring that the detection upper frame and the lower pressure sensing plate form a stable clamping and detection state for the gearbox, thereby accurately obtaining the vibration-related pressure data of the gearbox under different states, providing a basis for subsequent vibration analysis.

[0005] Further preferably, the auxiliary components also include an operation panel, which is located above the control console. A power cord is fixedly connected to one side of the control console, a cabinet door is hinged to one side of the control console, and a heat dissipation mesh is fixedly connected to one side of the control console. By installing the auxiliary components, the control console can serve as the core for control and data processing of the entire device. The power cord can be connected to an external power source to provide power to the control console and the entire testing device. The operation panel, located above the control console, allows operators to input testing parameters and issue testing commands, such as controlling the extension speed and stroke of the electric telescopic rod. The connecting line on one side of the upper frame transmits the pressure signal collected by the upper pressure sensor plate to the processing module inside the control console. Simultaneously, the signal from the lower pressure sensor plate is also transmitted to the control console via corresponding lines. The cabinet door protects the electronic components and circuits inside the control console, preventing dust and impurities from entering or being damaged by external impacts, thereby achieving effective control of the testing process, reliable data processing, and long-term stable operation of the device.

[0006] More preferably, the device base plate has a fitting groove on its upper part, a positioning hole is provided inside the fitting groove, a positioning bolt is threaded inside the fitting base frame, the fitting base frame is installed on the upper part of the device base plate by the positioning bolt, a movable push rod is fixedly connected to the top of the device base plate, and a caster wheel is provided at the bottom of the device base plate.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, by installing a detection component, when vibration detection of a wind turbine gearbox is required, the gearbox is first placed on a lower pressure sensing plate above the lower detection frame. Then, the electric telescopic rod is activated via a control console. The electric telescopic rod drives the splicing piece and the detection upper frame connected to the splicing piece downwards, causing the upper pressure sensing plate below the detection upper frame to gradually approach and fit against the top of the gearbox. During this process, the upper and lower pressure sensing plates sense the pressure applied to the gearbox in real time and transmit the pressure signal through relevant transmission structures. At the same time, the splicing bolts fix the relative position of the splicing piece and the detection upper frame, ensuring that the detection upper frame and the lower pressure sensing plate form a stable clamping and detection state for the gearbox. This allows for accurate acquisition of vibration-related pressure data of the gearbox under different conditions, providing a basis for subsequent vibration analysis.

[0008] In this invention, by installing auxiliary components, the control console can serve as the core for control and data processing of the entire device. The connecting wires can be connected to an external power source to provide power support for the control console and the entire testing device. The operation panel is located above the control console, allowing operators to input testing parameters and issue testing commands, such as controlling the extension speed and stroke of the electric telescopic rod. The connecting wire on one side of the upper frame transmits the pressure signal collected by the upper pressure sensor plate to the processing module inside the control console. At the same time, the signal from the lower pressure sensor plate is also transmitted to the control console through the corresponding lines. The cabinet door protects the electronic components and circuits inside the control console from dust, impurities, or damage from external impacts, thereby achieving effective control of the testing process, reliable data processing, and long-term stable operation of the device.

During this process, the upper pressure sensing plate 205 and the lower pressure sensing plate 207 will sense the pressure applied to the gearbox in real time and transmit the pressure signal through the relevant transmission structure. At the same time, the splicing bolt 5 can fix the relative position of the splice 203 and the detection frame 204, ensuring that the detection frame 204 and the lower pressure sensing plate 207 form a stable clamping and detection state for the gearbox.
