Technical Field
[0001] This utility model belongs to the technical field of pipeline processing equipment, and in particular relates to an industrial endoscope for detecting defects in the inner wall of a pipeline. Background Technology
[0002] Defect detection on the inner wall of extruded pipes is an important step in ensuring pipe quality and performance, especially in the process of plastic or metal extrusion molding. Common defect types include cracks, pores, impurities, uneven size, and inconsistent inner wall roughness. These defects can affect the performance and lifespan of the pipes.
[0003] Current methods for detecting defects on the inner wall of extruded pipes require visual inspection of the pipe's inner and outer surfaces by inspectors after processing to find obvious defects such as cracks, bubbles, and contaminants. However, pipes are mass-produced during extrusion, and problems inside the extruder head cannot be detected in time, easily leading to the production of batches of defective products and wasting resources. To address these issues, we provide an industrial endoscope for detecting defects on the inner wall of pipes. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1
[0022] Please see Figure 1-4 This utility model is an industrial endoscope for detecting defects in the inner wall of a pipe, including an extrusion mold 1, a glue injection tube 2 connected to the top of the extrusion mold 1, a pipe blank 3 arranged on one side of the extrusion mold 1, a ventilation tube 4 arranged inside the pipe blank 3, and an industrial endoscope 5 fixedly connected to the surface of the ventilation tube 4; a ventilation assembly is arranged on one side of the extrusion mold 1, the ventilation assembly includes a protective cover 6, the protective cover 6 is fixedly connected to the surface of the industrial endoscope 5, a heat sink 7 is fixedly connected to the surface of the industrial endoscope 5, and a blower 8 is connected to one end of the ventilation tube 4; a cooling assembly is arranged on the other side of the extrusion mold 1, the cooling assembly includes a support box 9, the support box 9 is arranged on one side of the extrusion mold 1, a wireless transmission terminal 10 is installed at the bottom of the support box 9, and a cooler 11 is installed inside the support box 9.
[0023] Specifically, there are three industrial endoscopes 5, arranged in a circle around the ventilation duct 4. Each set of industrial endoscopes 5 can detect a range of 140 degrees. The industrial endoscopes 5 help inspectors discover potential defects by providing direct images of the inside of the pipe. The core component of the industrial endoscope 5 is a small camera (usually a high-definition CMOS or CCD camera). When the endoscope is inserted into the pipe, the camera captures real-time images of the inside of the pipe through its lens. After the captured images are sent to the display via the wireless transmission terminal 10, the operator can observe the condition of the inner wall of the pipe, such as whether there are defects such as cracks, corrosion, deposits, and blockages. When rubber hoses malfunction or have quality problems during processing, the industrial endoscopes can conduct detailed inspections of the recovered products to help analyze the cause of the malfunction and provide a reference for improving production processes and product design, thereby improving product quality and performance.

[0025] Please see Figure 1-4 Based on Embodiment 1, a bracket 12 is fixedly connected to the surface of the ventilation pipe 4, and an air supply pipe 13 is fixedly connected to the surface of the bracket 12. The other end of the air supply pipe 13 extends into the support box 9 and is connected to an exhaust pipe 14. The other end of the ventilation pipe 4 extends into the support box 9 and is connected to an air inlet pipe 15. A movable shaft 16 is installed inside the air inlet pipe 15, and a first fan blade 17 is fixedly connected to the surface of the movable shaft 16. A support shaft 18 is installed inside the exhaust pipe 14, and a second fan blade 19 is fixedly connected to the surface of the support shaft 18. A dual-axis motor 20 is installed at the top of the air inlet pipe 15. One output end of the dual-axis motor 20 extends into the air inlet pipe 15 and is fixedly connected to a first pulley 21. A second pulley 22 is fixedly connected to the surface of shaft 16. The first pulley 21 and the second pulley 22 are connected by belt drive.

The heating end of the cooler 11 extends into the outside of the support box 9 and is fixedly connected to a heat dissipation fin 25. The cooling end of the cooler 11 extends into the air inlet pipe 15 and is fixedly connected to a temperature-conducting fin 26. A connecting cable 27 is installed on one side of the wireless transmission terminal 10. The other end of the connecting cable 27 is fixedly connected to the industrial endoscope 5.
[0026] Specifically: A good bond between the inner lining and the reinforcing layer is crucial for the quality of rubber hoses. An industrial inspection lens 5 can check for voids, delamination, or other defects between the two layers, ensuring a tight bond and improving the overall performance of the rubber hose. During critical processes such as extrusion and vulcanization, the industrial inspection lens 5 helps operators monitor the forming process of the rubber hose in the mold in real time. For example, it allows observation of the rubber flow during extrusion, determining the rationality of the mold design and identifying any blockages or poor flow. This enables timely adjustments and optimization of the mold, improving production efficiency and product quality. Furthermore, it allows for equipment cleanliness checks: during production, impurities or residual materials inside the equipment may mix into the rubber hose, affecting product quality. Using an industrial inspection lens 5 allows for regular checks of the internal cleanliness of production equipment, enabling timely detection and removal of impurities, ensuring a clean production environment, and reducing product defects.
[0027] The working principle of this utility model is as follows: During the extrusion process of the pipe blank 3 through the extrusion die 1, the industrial sight glass 5 can penetrate deep into the hose to observe the tightness and uniformity of the steel wire braiding or winding, as well as whether there are broken or missing wires. This is crucial for ensuring the strength and high pressure resistance of the rubber hose. If defects in the steel wire braiding or winding are found during the production process, the machine can be stopped in time for repair or adjustment to prevent unqualified products from flowing into the next process. After the rubber hose is produced, the finished product is sampled and inspected through the industrial sight glass 5, which can comprehensively and intuitively check the internal quality of the product to ensure that the product meets the quality standards.
[0028] During the inspection process of the industrial endoscope 5, when its operating temperature is high, the cooler 11 and the dual-axis motor 20 can be started by an external controller. The cooling end of the cooler 11 will reduce the temperature inside the air inlet pipe 15. When the dual-axis motor 20 is driven, it can drive the first pulley 21 to rotate. The first pulley 21, together with the second pulley 22, drives the movable shaft 16 and the first fan blade 17 to rotate. The first fan blade 17 drives the airflow, so that the cooled gas is discharged into the ventilation pipe 4 and discharged through the air blowing pipe 8, which takes away the heat conducted by the surface of the heat sink 7, which can effectively improve the heat dissipation effect of the industrial endoscope 5. The dual-axis motor 20 can also drive the first bevel gear 23 to rotate at the same time. The first bevel gear 23, together with the second bevel gear 24, drives the support shaft 18 and the second fan blade 19 to rotate. The second fan blade 19 drives the airflow, and the hot air generated by the industrial endoscope 5 is discharged through the air supply pipe 13, further improving the heat dissipation effect.
