Detailed ways

Hereinafter, the present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

In this embodiment, a method for analyzing the position of a foundation defect of a wind turbine is provided, as shown in FIG. 1 , the method includes:

Step 101: Obtain the surface temperature of the structure to be inspected, determine an abnormal temperature region based on the surface temperature of the structure to be inspected, and determine the abnormal temperature region as a target defect region;

In the analysis method for the position of the foundation defect of the wind turbine provided by the present application, firstly, the surface temperature of the structure to be detected can be obtained. The structure to be detected may be the foundation of the wind turbine. The surface temperature of the structure to be inspected can be calculated from the thermal radiation energy value measured by an infrared thermal imager. Infrared thermal imaging, corresponding to thermal imaging cameras, is a non-destructive technique for measuring infrared radiation emitted by objects. The wind turbine foundation can be considered as a homogeneous material, however, if there is delamination under the surface of the wind turbine foundation, the continuity of the material will be interrupted and the heat transfer characteristics will change. The thermal radiation energy value corresponding to the structure to be detected can be detected by an infrared thermal imager, and a heat map can be generated. When the wind turbine foundation is layered, the corresponding heat map can display different colors, representing different thermal radiation energy values. , and then different surface temperatures can be calculated according to different thermal radiation energy values. After the surface temperature of the structure to be detected is obtained, an abnormal temperature region can be determined from the surface region of the structure to be detected based on the surface temperature of the structure to be detected. The temperature corresponding to the abnormal temperature region is significantly different from that of other regions. After the abnormal temperature area is determined, the abnormal temperature area can be used as the target defect area.

Step 102 , based on the ground penetrating radar, transmit a detection signal to the target defect area, collect the corresponding detection reflection signal, and determine the target defect depth of the structure to be detected according to the detection reflection signal.

In this embodiment, after the target defect area is determined, a detection signal may be sent to the target defect area through a ground penetrating radar based on the target defect area. Ground Penetrating Radar, also known as Surface Penetrating Radar or Electromagnetic Reflection Method, is a method that utilizes electromagnetic detection. In reflection mode, the transmitter sends a wave to the structure being detected, and due to discontinuities in the material, a portion of the energy is reflected back to the GPR, while another portion continues through the structure, and the reflected signal is recorded by the receiver. A discontinuity in a material can be a boundary or interface between two materials with different dielectric properties, or an interface between subsurface objects such as desliming or delamination. Based on the arrival time of the reflected waves and the speed of the radar waves, the location of the layers in the material can be determined. After the ground penetrating radar transmits the detection signal to the target defect area, the corresponding detection reflection signal is collected in real time, and then the target defect depth corresponding to the target defect area can be determined according to the detection transmission signal.

By applying the technical solution of this embodiment, first, the surface temperature of the structure to be detected can be obtained first, and after the surface temperature of the structure to be detected is obtained, the surface temperature of the structure to be detected can be further based on the surface area of the structure to be detected. The abnormal temperature area is determined and the abnormal temperature area is used as the target defect area. After determining the target defect area, you can use the target defect area as the basis to transmit detection signals to the target defect area through ground penetrating radar, and collect the corresponding detection reflection signals in real time. be determined. In the embodiment of the present application, the target defect area is quickly determined according to the surface temperature of the structure to be inspected, and then the target defect depth of the target defect area is quickly determined according to the ground penetrating radar, which can improve defect analysis efficiency and increase defect location accuracy.

Further, as a refinement and extension of the specific implementation manner of the above-mentioned embodiment, in order to fully describe the specific implementation process of this embodiment, another method for analyzing the position of the foundation defect of the wind turbine is provided, as shown in FIG. 2 , the method includes: :

Step 201, acquiring the surface radiation energy value, relative permittivity and target material constant of the structure to be detected, and determining the surface temperature of the structure to be detected;

In this embodiment, the surface radiant energy value of the structure to be inspected can be determined by an infrared thermal imager. When the infrared thermal imager irradiates the structure to be inspected, it can generate a corresponding heat map of the surface of the structure to be inspected, and the heat map can display areas of different colors and corresponding surface radiant energy values. The surface radiant energy value corresponding to the infrared thermal imager follows the Stephan-Boltzmann law, and the surface radiant energy value can be converted into temperature, which can be converted according to the formula E=εσT ⁴ , where E represents the surface radiant energy value, and ε represents the relative medium. The electric constant, σ represents the target material constant related to the material, specifically the Stephan-Boltzmann constant. Since the basic material of the wind turbine is concrete, it can be a constant related to the concrete material here. Then, the surface temperature corresponding to different surface radiant energy values can be calculated through the surface radiant energy value, relative permittivity, and target material constant.

Step 202: Obtain the surface temperature of the structure to be detected, and determine the area of the temperature region corresponding to each surface temperature based on the surface temperature of the structure to be detected; The temperature area is used as the abnormal temperature area, and the abnormal temperature area is determined as the target defect area;

In this embodiment, after calculating the surface temperature of the structure to be detected, the surface temperature of the structure to be detected can be acquired, and further according to the surface temperature of the structure to be detected, the temperature regions corresponding to each surface temperature are determined, and these temperature regions are determined respectively area. Among them, even if some areas are not connected, as long as the surface temperatures corresponding to these areas are the same, they are regarded as the same temperature area. Next, consider the temperature area with the largest area among these temperature areas as the area without defects in the foundation of the wind turbine, and consider other temperature areas as abnormal temperature areas. There are very likely defects in the abnormal temperature areas, so these abnormal temperature areas can be regarded as Determine the target defect area to search for defects.

Step 203: Divide the target defect area according to a preset step size, and determine a plurality of detection sites; based on the ground penetrating radar, transmit a detection signal to any of the detection sites, and collect the corresponding detection signals. at least one detection reflection signal, bind each detection reflection signal to any of the detection sites, obtain at least one detection reflection signal after binding, and repeat the detection to the other detection sites Sending a detection signal ends when the plurality of detection sites all obtain the corresponding detection reflection signal after binding;

In this embodiment, in order to accurately determine the defect depth corresponding to the target defect area, the target defect area may be further divided into grids, and may be divided according to a preset step size. The preset step size can be determined empirically. After meshing the target defect area, the mesh vertices can be used as detection points, and then multiple detection points can be determined. The ground penetrating radar can be used to transmit detection signals to these detection sites one by one. Specifically, a detection signal can be transmitted to one detection site first, and after all detection reflection signals corresponding to the detection signal are received, the detection signal can be sent to the next detection site. Signal. Before transmitting the detection signal to the detection site through the GPR, a maximum reflection time can be determined according to the thickness of the foundation of the wind turbine. When the time for the GPR to transmit the detection signal has exceeded the maximum reflection time, it can be considered that all the detection signals After the detection reflection signal is received, the detection signal is then transmitted to the next detection site. Due to the material change between the foundation of the wind turbine and the ground, each detection signal corresponds to at least one detection reflection signal. After collecting one or more detection reflection signals corresponding to each detection site, each detection reflection signal can be bound to the detection site to obtain multiple bound detection reflections corresponding to each detection site Signal. Finally, when all the detection sites obtain the corresponding detection reflection signals after binding, the operation ends.

Step 204, determining the target three-dimensional model corresponding to the target defect area based on the bound detection reflection signal, and determining the target defect depth of the structure to be detected based on the target three-dimensional model;

In this embodiment, based on all bound detection reflection signals corresponding to all detection sites, a three-dimensional target model corresponding to the target defect area can be determined, wherein the two coordinate axes in the target three-dimensional model correspondingly represent the to-be-detected The surface position of the structure, and the other coordinate axis corresponds to the target defect depth. Therefore, the target defect depth can be directly determined from the target three-dimensional model, and at the same time, the specific position of the target defect depth on the surface of the structure to be inspected can be determined more clearly and Intuitive.

Step 205 , based on the concrete detector, determine whether there is a preset steel structure object in the target defect area, and when there is, remove the target defect area.

In this embodiment, some target defect areas may be misjudged due to the existence of preset steel structure objects in the foundation of the wind turbine. Here, the preset steel structure objects may be steel bars or the like. In order to avoid the influence of these preset steel structure objects on the determination of target defect areas, a concrete detector can be used to determine which target defect areas are caused by the preset steel structure objects. Determining the depth of the target defect in the defect area, avoiding the waste of manpower and material resources, and improving the efficiency of defect determination.

Optionally, in step 204, "determining the target three-dimensional model corresponding to the target defect area based on the detected reflection signal after the binding" specifically includes: based on any of the bound Detect the detection site corresponding to the reflection signal, and identify the coordinate value corresponding to the detection site; according to the signal transmission time of the transmission signal corresponding to the detection site, and the signal of the detection reflection signal corresponding to the detection site Receiving time, determine the target time difference; based on the target time difference and the signal propagation speed of the ground penetrating radar, determine the target reflection depth corresponding to the detection site; based on the coordinate value corresponding to each of the detection sites and at least one The target reflection depth is determined, and the three-dimensional model of the target is determined.

In this embodiment, the three-dimensional model of the target may include three coordinate axes, two of which may be used to represent the specific position of the surface of the structure to be detected, and the other coordinate axis may be used to represent the reflection depth of the target. The coordinate value corresponding to the detection site can be identified from each bound detection reflection signal. The coordinate value of the detection site can be represented by the two coordinate axes used to represent the specific position of the surface of the structure to be detected in the target 3D model. in the 3D model of the target. Next, the signal transmission time of the transmission signal corresponding to each detection site and the signal reception time of the detection reflection signal corresponding to the detection site may be determined, and the target time difference of the detection reflection signal may be determined. When there are multiple detection reflection signals corresponding to any detection site, the receiving time of multiple signals is recorded, and the target time difference of each detection reflection signal is determined respectively. Based on the time difference and the signal propagation speed of the ground penetrating radar, one or more target reflection depths can be calculated. After one or more target reflection depths of each detection site are determined, points can be traced in the 3D model with the corresponding coordinate values of the detection site and the target reflection depth, and finally a 3D model of the target is obtained.
