Description

Technical Field

[0001] This utility model relates to the field of borehole detector technology, and in particular to an intelligent borehole detector that supports visual inspection algorithms. Background Technology

[0002] A borescope is a non-destructive testing device used in the maintenance of aero engines. It is primarily used to inspect the internal structures of aero engines, such as blades, combustion chamber walls, and other areas that cannot be directly observed from the outside, for defects such as structural cracks, ablation, and corrosion. This aims to prevent aero engine accidents and improve the safety of civil aviation operations. Due to the aviation industry's emphasis on safety, users have placed new and higher demands on the functionality and performance of borescopes.

[0003] During aero-engine maintenance, the main areas requiring borehole inspection include blades and the combustion chamber walls. Blades consist of multi-stage axial rotors and stators, with each stage containing dozens of blades. Blade damage can manifest as cracks, wear, ablation, and fracture. Combustion chamber wall damage includes cracks, ablation, and carbon buildup. Due to the diverse damage types in different areas, the large number of blades and combustion chamber components, and the significant workload involved in borehole inspection, operators are prone to missed or incorrect detections, necessitating improvements in the efficiency and accuracy of damage detection.

[0004] Meanwhile, as a handheld device, the borehole probe often uses a plastic shell with poor thermal conductivity in order to reduce weight. However, the need to run intelligent detection algorithms drives the borehole probe to use a high-computing-power, high-energy-consumption main control chip, resulting in a bottleneck in the overall heat dissipation capacity.

[0045] It can be recognized that this embodiment, through the detachable design of the main control module, allows for the replacement of core boards with different signals, and can support the development and application of complex visual inspection algorithms.

[0046] As a further optional implementation, the base plate module includes a host connector, and the probe module also includes a probe connector, the probe module being detachably connected to the host connector via the probe connector.

[0050] It can be recognized that this embodiment, through the detachable design of the probe module, allows for the replacement of different types of probes, thus achieving adaptation to different tasks.

[0051] As a further optional implementation, the heat sink is made of aluminum alloy and includes a raised portion and an integrated airflow channel. The raised portion contacts the main control module, and the integrated airflow channel is used to increase the contact area between the heat sink and the air.

[0052] Specifically, Figure 4 A schematic diagram of the base plate module, heat sink, and probe module of an intelligent borehole probe supporting a visual inspection algorithm, provided for an embodiment of this utility model, is shown below. Figure 4 In this embodiment, an aluminum alloy heat sink is used to improve thermal conductivity, alleviating the contradiction between the poor heat dissipation of the lightweight plastic casing and the high energy consumption of the equipment. Simultaneously, the aluminum alloy heat sink not only serves a heat dissipation function but also acts as an intermediate component in the entire structure. The base plate and probe module are tightly assembled via the heat sink, and the host connector on the base plate and the probe connector on the probe module are connected through holes in the heat sink. The heat sink is designed with a protruding portion that directly contacts the main heat-generating module (main control module) on the base plate, greatly increasing the contact area between the heat sink and the overall structure, thus improving heat dissipation efficiency.

[0054] Specifically, Figure 5 A schematic diagram of a cooling fan for an intelligent borehole probe supporting a visual inspection algorithm, provided for an embodiment of this utility model, is shown below. Figure 5In this embodiment, heat dissipation is achieved through a cooling fan. The cooling fan is installed axially on the handle of the borehole probe main unit. Due to the limited space at the handle, a small cooling fan measuring 30*30mm with an airflow of approximately 1.7 CFM is used. When the temperature sensor on the main control module detects that the temperature exceeds a threshold, the cooling fan automatically activates. Airflow enters the device through the handle hole and exits through the outer casing hole, forming an airflow channel inside the borehole probe. This increases the airflow rate near the heat sink, achieving rapid heat dissipation. According to simulation results, adding air cooling can reduce the internal temperature of the device by more than 10 degrees Celsius, demonstrating a significant heat dissipation and cooling effect.

[0055] As an optional implementation, the baseboard module also includes a display device interface, a charging interface, and a data export interface.

[0056] Specifically, Figure 6 A schematic diagram of the base plate module, heat sink, and probe module of an intelligent borehole probe supporting a visual inspection algorithm, provided for an embodiment of this utility model, is shown below. Figure 6 In this embodiment, the base plate is provided with a display device interface, a charging interface, and a data export interface. The display device interface can transmit the image information captured by the camera module to an external display device via the HDMI bus, thereby displaying the image interface of the display module on the external display device and realizing the functions of real-time screen projection and image sharing. The charging interface is a USB Type-C interface, which can charge the battery module through a charging device. The data export interface is a MicroSD interface. In this embodiment, the MicroSD card is used as a storage module for storing image information and damage identification results. Through the MicroSD card, which can be quickly physically unloaded, the image information and damage identification results stored in the MicroSD card can be quickly copied to other data receiving devices to support further data analysis.

[0057] As an optional implementation, the smart borehole probe also includes a charging indicator light, and the camera module includes a camera and a searchlight. The charging indicator light is mounted on the front of the borehole probe main unit.

[0058] Specifically, Figure 7 A front view schematic diagram of an intelligent borehole probe supporting a visual inspection algorithm provided for an embodiment of this utility model, with reference to... Figure 7 In this embodiment, the charging indicator light illuminates when the borehole probe is connected to an external charging device for charging. The camera module is contained within the probe wire extending from the probe module (not shown in the figure). The rocker handle of the probe module has a mechanical linkage structure inside. When the rocker handle is turned, it drives the camera to rotate, thereby achieving multi-angle detection. The searchlight is an LED lighting lamp. During use, the brightness of the searchlight can be controlled by operating the button module.

[0059] As an optional implementation, the smart borehole probe also includes anti-slip stripes and a hand strap, with the anti-slip stripes located on the front of the borehole probe main unit and the hand strap installed on the back of the borehole probe main unit.

[0060] Specifically, refer to Figure 6 and Figure 7 In this embodiment, the handle of the borescope main unit is provided with anti-slip stripes on the front to increase friction, and a hand guard is provided on the back to prevent it from being dropped when held.

[0065] Reference Figure 1When the borescope is in operation, its various modules work together to achieve its overall function: the camera module captures real-time video of the internal environment of the aero-engine using a camera, forming a video stream, which is transmitted to the main control module via a USB 2.0 bus. The camera module is also equipped with an LED light to assist in achieving clear imaging. The main control module performs real-time calculations on the incoming video stream data, using visual inspection algorithms to identify the location and damage type of potential structural defects, and transmits this data to the display module via a MIPI bus to present the video image and defect identification results to the user. During use, the operation button module allows for function control of the borescope, including LED light brightness control, display module screen brightness control, video image zooming, and initiating screen recording or screenshotting. The display device interface on the base plate module supports connection of the borescope to other display devices via an HDMI bus, enabling real-time screen projection and image sharing. The borescope can also copy stored images and defect identification data to other data receiving devices via a quickly removable MicroSD Card storage module to support further data analysis. The borescope's battery module allows it to operate without a power source, via USB... The Type-C interface allows charging devices to be connected to the battery module to replenish power.

[0066] The workflow of this embodiment is as follows: video data of the parts inside the aero-engine that need to be inspected by borehole detection is acquired through the camera module; the visual inspection algorithm is run through the main control module to analyze and calculate the video data, and identify the possible defect locations and damage forms in the borehole video data; the borehole video data and damage identification data are displayed through the display module to assist the operator in judging the borehole inspection results; the acquired video / image information and damage identification results are saved to the storage module; if further analysis is needed, the stored data can be transferred to other analysis equipment through the quickly detachable storage module.

[0067] It can be recognized that this embodiment, through its modular hardware design, allows for the individual replacement of the probe module, enabling the borescope to be equipped with different probe models to adapt to various tasks. Simultaneously, this embodiment supports the plug-and-play replacement of the main control core board from the baseboard, allowing for the replacement of different core board models. This supports continuous updates and development of intelligent detection algorithms, expanding the applicable scenarios of the device. Addressing the heat dissipation requirements of high-computing-power, high-power SoCs operating for extended periods, this embodiment integrates a large heat sink into the hardware structure to enhance heat conduction.
