TECHNICAL FIELD The present disclosure relates to the technical field of pipeline endoscopes, and in particular, to a pipeline endoscope probe. BACKGROUND As a pipeline inspection device, the pipe endoscope enables people to visually inspect the interior of pipelines without disassembly or entry, it facilitates maintenance, daily upkeep, and troubleshooting operations. Beyond its use in high-temperature, toxic, or radioactive environments where direct human observation is impossible, it is also employed for video inspection of ventilation ducts, air conditioning pipelines, water pipes, industrial pipelines, internal welds, corrosion, blockages, irregularities, and foreign objects, this significantly enhances convenience in work and daily life. Due to the diverse types of issues present within pipelines and the complex and variable potential causes, on-site personnel often encounter difficulties during troubleshooting. Additionally, existing pipeline endoscope devices on the market face technical limitations in image capture, resulting in generally low-quality images with insufficient clarity and poor detail representation. This makes it challenging for workers to accurately identify and locate the specific fault positions and root causes, thereby affecting the efficiency and effectiveness of problem resolution. SUMMARY In response to the technical limitations in image acquisition of existing pipeline endoscope equipment, such as generally low-quality visuals, insufficient clarity, and poor detail representation, which hinder workers' ability to accurately identify and locate the specific locations and root causes of faults, this utility model provides a pipeline endoscope solution to address the aforementioned technical issues. Apipeline endoscope probe includes a shell, and an image acquisition device. The shell is provided with an accommodating chamber with an image acquisition window in communication with the accommodating chamber. The image acquisition device is positioned within the accommodating chamber and oriented toward the image acquisition window to acquire image; the image acquisition device includes a camera motor for adjusting a focal length thereof, and the camera motor is electrically connected to an external control device, the focus acquisition device is capable of automatically adjusting the focal length, or the focus acquisition device is capable of being manually adjusted the focal length through the external control device. A pipeline detection system connected to the above pipeline endoscope probe, includes a display screen for displaying images detected by the pipeline endoscope probe; and a focusing button used to remotely control the camera motor to adjust the focal length of the image acquisition device, so that the display screen shows corresponding images detected by the pipeline endoscope probe.
