Description

Technical Field

[0001] The utility model relates to the field of endoscopes used for non-destructive flaw detection of pipelines, and more specifically, to an endoscope used for non-destructive flaw detection of pipelines. Background Art

[0002] Pipeline endoscopes can be used for inspection and observation of places with high temperature, toxicity, nuclear radiation and places that cannot be directly observed by human eyes. This method is mainly used in automobiles, aircraft engines, pipelines, mechanical parts, etc. It can achieve non-destructive testing without disassembling or destroying the assembly and stopping the equipment. It can also be used for video detection of internal welds, corrosion, blockage, differences, foreign matter, etc. in ventilation ducts, air-conditioning ducts, water pipes, and industrial pipelines. Existing pipeline endoscopes still have certain defects when used, such as;

[0003] Traditional pipeline endoscopes require the probe to be inserted into the pipeline. During the insertion process, the probe will rub against the inner wall of the pipeline, causing damage to the probe. When the probe enters the bend of the pipeline, one end of the probe will collide with the pipeline, causing damage to the lens of the probe.

[0004] Its CN218413051U discloses a wear-resistant pipeline endoscope, comprising: a pipeline endoscope body, a handle fixedly connected to the bottom of the pipeline endoscope body, a wire connected to the top of the pipeline endoscope body, one end of the wire connected to a probe, and a protective shell arranged on the outside of the probe. The wear-resistant pipeline endoscope forms a protective structure by providing a ball, a protective shell, a sliding rod, a spring, a buffer plate and a rubber pad. When the probe enters the pipeline, the ball will rotate to avoid friction damage to the probe shell, and when the probe lens contacts the pipeline, the spring and the buffer plate will buffer the impact to a certain extent to avoid damage to the lens due to collision, thereby ensuring the long-term use of the probe. A wire storage structure is formed by providing a motor, a rotating rod, a take-up wheel, a fixing plate and a fixing bolt. By starting the motor to wind the wire onto the take-up wheel, it is convenient for the staff to unfold or store the wire, thereby facilitating the development of detection work.

[0005] In the above-mentioned patent, a ball structure and a protective structure are provided on the outer surface of the probe to avoid collision damage to the lens. However, during use, the lens will rub against the inner wall of the pipe and collide with the inner wall of the pipe, which will wear the inner wall of the pipe. During observation, the lens and the inner wall of the pipe will fit and rub against each other, resulting in incomplete capture, which affects shooting and observation. Utility Model Content
