Description

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. Currently, when existing pipeline endoscopes are in use, the probe often rotates inside the pipe along with the guide wire, during this process, the observed images are flipped, causing inconvenience for users to inspect the pipe's interior. Additionally, since the images appear reversed, it becomes difficult to accurately determine the specific locations of welds, corrosion, blockages, discrepancies, or foreign objects, this prevents users from intuitively understanding the pipe's internal conditions and affects their judgment. To address this, the present invention provides a pipeline endoscope probe that effectively resolves the aforementioned issues, it features a simple structure and can automatically adjust the orientation of the lens, thereby modifying the image orientation, making it user-friendly. SUMMARY In order to overcome the shortcomings of existing technology, the present invention provides a pipeline endoscope probe and a pipeline endoscope assembly, which have a simple structure, can adjust the orientation of the image, and are convenient for users to use. Apipeline endoscope probe includes a shell, an image acquisition device, a driving/adjusting device, a first control board, a first control board and a rotating electrical connector. 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. The driving/adjusting device is used to adjust the image acquisition angle of the image acquisition device, ensuring that an image displayed on a display of a detection system connected to the image acquisition device remains upright. The first control board is fixedly installed inside the accommodating chamber. The rotating electrical connector is arranged inside the accommodating chamber, and the rotating electrical connector includes a fixing component and a rotatable component electrically connected to the fixing component. The rotatable component is capable of rotating relative to the fixing component. The image acquisition device is electrically connected to the rotatable component through a first electrical connection line, and the fixing component is electrically connected to the first control board through a second connection line. When the driving/adjusting device rotates, the rotatable component follows the rotation of the driving/adjusting device, and the fixing component maintains its original state relative to the rotatable component. A pipeline detection system includes a cable, and a display displaying images detected by a pipeline endoscope probe; one end of the cable is electrically connected to the display, and the other end of the cable is electrically connected to a first connector of the pipeline endoscope probe, thereby the cable is electrically connected with the pipeline endoscope probe and capable of transmitting the detected image to the display. A pipeline endoscope assembly includes the pipeline endoscope probe and the pipeline detection system featured above. The beneficial effects of the present invention are as follows: through the above structure, when in use, the driving/adjusting device is used to adjust the image acquisition angle of the image acquisition device, so that the image displayed by the display according to the image signal always remains forward, preventing the image acquisition device from rotating with the pipeline endoscope probe when the pipeline endoscope probe is inserted into the pipeline, maintaining the stability of the image acquired by the image acquisition device, allowing users to better see the situation inside the pipeline based on the information collected by the image acquisition device, rotating the electrical connector to prevent wire entanglement, enabling the driving/adjusting device to move better, improving the activity stability of the driving/adjusting device, and matching the detection system application to be more convenient for users to use, improving the user's experience.
