Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial endoscope technology, specifically to an anti-fouling structure for industrial endoscopes. Background Technology
[0002] Industrial endoscopes are multidisciplinary inspection tools primarily used to inspect and observe the internal structure of objects without disassembling or damaging them. They can extend the human field of vision, helping inspectors to observe areas inaccessible by sight, such as deep within winding pipes, in real time without damaging the structure or removing pipes, thereby discovering defects.
[0003] Existing industrial endoscopes are often used to inspect the internal condition of equipment. However, dust often accumulates inside the equipment. When an industrial endoscope is inserted into the equipment, it is difficult to avoid contact with the inner wall of the equipment. Dust on the industrial endoscope will cause unclear imaging, resulting in false or missed measurements. Therefore, we propose an anti-fouling structure for industrial endoscopes to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a contamination-proof structure for industrial endoscopes, in order to solve the problem that when industrial endoscopes are inserted into equipment, they inevitably come into contact with the inner wall of the equipment, and dust contamination on the industrial endoscopes can lead to unclear imaging, resulting in mismeasurements or missed measurements.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A contamination-proof structure for an industrial endoscope includes an endoscope housing and a probe cable. The probe cable is mounted on the upper end of the endoscope housing, and a probe is mounted on the right end face of the probe cable. A limit plate is fixedly connected to the outer right side of the probe, and an external threaded sleeve is fixedly connected to the outer right side of the probe. An internal threaded protective sleeve is detachably threaded to the outer side of the external threaded sleeve. A protective transparent glass lens is mounted on the inner right side of the internal threaded protective sleeve. An air collecting groove is formed on the inner upper end of the internal threaded protective sleeve, and a connecting pipe is fixedly connected to the lower right side of the air collecting groove. An air outlet pipe is fixedly connected to the lower end of the connecting pipe. An air inlet pump is mounted on the upper end of the endoscope housing, and a ventilation hose is mounted on the upper end of the air inlet pump. A connector is mounted on the other end of the ventilation hose. A controller is mounted on the inner front end of the endoscope housing.
[0007] Preferably, the probe, air pump, and controller are electrically connected, and the limiting plate is circular in shape.
[0008] Preferably, the probe wire length is the same as the ventilation hose length, the right end of the limiting plate and the left end of the external threaded sleeve are fixedly connected, and the right end face of the limiting plate and the left end face of the internal threaded protective sleeve are in contact.
[0009] Preferably, the protective transparent glass mirror is circular in shape and is located on the right side of the probe. The air outlet pipe is annular in shape and has multiple air outlet nozzles installed on its inner side. The air outlet pipe is located on the right side of the protective transparent glass mirror, and the outer side of the air outlet pipe is fixedly connected to the inner side of the internally threaded protective sleeve.
[0010] Preferably, the air inlet pump is located to the left of the probe line, and the lower outer side of the connector and the upper left inner side of the internal thread protective sleeve are detachably threadedly connected. The ventilation hose, connector, air collection groove, connecting pipe, air outlet pipe and air outlet are interconnected.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, by setting a limiting plate, an external threaded sleeve, an internal threaded protective sleeve, a protective transparent glass mirror, an air collecting trough, a connecting pipe, an air outlet pipe, an air inlet pump, a ventilation hose, and a connector, when the probe enters the equipment for testing, the internal threaded protective sleeve, the protective transparent glass mirror, and the air outlet pipe enter the equipment's interior together with the probe. The internal threaded protective sleeve can provide some protection for the probe, reducing wear caused by direct contact between the probe and the equipment's inner wall. The protective transparent glass mirror acts as a contaminant for the probe, reducing the direct adhesion of dust inside the equipment to the probe and affecting image clarity. Then, when dust adheres to the outer surface of the protective transparent glass mirror, the air inlet pump is activated. The air inlet pump blows air into the air collecting trough through the ventilation hose and connector, then into the connecting pipe and the air outlet pipe, and finally out of the air outlet nozzle. This allows the air to blow away the dust adhering to the surface of the protective transparent glass mirror, keeping the surface of the protective transparent glass mirror clean, resulting in clearer images taken by the probe and reducing the occurrence of false or missed measurements due to dust obstruction.

[0022] A contamination-proof structure for an industrial endoscope includes an endoscope housing 1 and a probe cable 2.

The right end face of the limiting plate 4 is attached to the left end face of the internal threaded protective sleeve 6. The protective transparent glass mirror 7 is circular in shape and is located to the right of the probe 3. The air outlet pipe 10 is circular in shape and has multiple air outlets installed inside. The air outlet pipe 10 is located to the right of the protective transparent glass mirror 7. The outer side of the air outlet pipe 10 is fixedly connected to the inner side of the internal threaded protective sleeve 6. The air pump 11 is located to the left of the probe line 2. The lower outer side of the connector 13 is attached to the internal threaded protective sleeve 6. The upper left inner side of the sleeve 6 has a detachable threaded connection. The ventilation hose 12, connector 13, air collection trough 8, connecting pipe 9, air outlet pipe 10, and air nozzle are interconnected. The endoscope housing 1 has a probe wire 2 installed on its upper end. The probe 3 is installed on the right end face of the probe wire 2. The right outer side of the probe 3 is fixedly connected to a limit plate 4 for easy installation. The sleeve 5 is externally threaded, the sleeve 6 is internally threaded, the transparent glass mirror 7 is protective, the air collection trough 8 is connected, the connecting pipe 9 is air outlet pipe 10, the air inlet pump 11 is air pump 11, the ventilation hose 12, and the connector 13 are also connected. When the probe 3 enters the equipment for testing, the internally threaded protective sleeve 6, the transparent glass mirror 7, and the air outlet pipe 10 enter the equipment together with the probe 3. The internal threaded protective sleeve 6 provides some protection for the probe 3, reducing wear caused by direct contact between the probe 3 and the inner wall of the equipment. The protective transparent glass mirror 7 acts as a contaminant for the probe 3, reducing the direct adhesion of dust from inside the equipment to the probe 3 and affecting image clarity. When dust adheres to the outer surface of the protective transparent glass mirror 7, the air intake pump 11 is activated. The air intake pump 11 blows air into the air collection slot 8 through the ventilation hose 12 and connector 13, then into the connecting pipe 9 and the air outlet pipe 10, and finally out of the air outlet nozzle. This airflow blows away the dust adhering to the surface of the protective transparent glass mirror 7, keeping the surface of the protective transparent glass mirror 7 clean and ensuring the probe 3... The imaging is clearer, reducing the occurrence of false or missed measurements due to dust obstruction; an external threaded sleeve 5 is fixedly connected to the outer right side of the probe 3, and an internal threaded protective sleeve 6 is detachably threaded to the outer side of the external threaded sleeve 5. A protective transparent glass mirror 7 is installed on the inner right side of the internal threaded protective sleeve 6. An air collection groove 8 is opened on the inner upper end of the internal threaded protective sleeve 6. A connecting pipe 9 is fixedly connected to the lower right side of the air collection groove 8. An air outlet pipe 10 is fixedly connected to the lower end of the connecting pipe 9. An air inlet pump 11 is installed on the upper end of the endoscope housing 1. A ventilation hose 12 is installed on the upper end of the air inlet pump 11. A connector 13 is installed on the other end of the ventilation hose 12. A controller 14 is installed on the inner front end of the endoscope housing 1.
[0024] Workflow: When in use, the device is powered by an external power source. The endoscope housing 1, probe wire 2, probe 3, and controller 14 constitute the endoscope. When probe 3 is inserted into the device for testing, the internal threaded protective sleeve 6, the protective transparent glass mirror 7, and the air outlet pipe 10 enter the device along with probe 3. The internal threaded protective sleeve 6 provides some protection for probe 3, reducing wear caused by direct contact between probe 3 and the inner wall of the device. The protective transparent glass mirror 7 prevents dust from directly adhering to probe 3, thus reducing the impact on image clarity. Then, when dust adheres to the outer surface of the protective transparent glass mirror 7, the air intake pump 11 is activated. The air intake pump 11 blows air into the air collection slot 8 through the ventilation hose 12 and connector 13, then into the connecting pipe 9 and the air outlet pipe 10, finally exiting through the air collection slot 8. The air outlet blows air to remove dust adhering to the surface of the protective transparent glass mirror 7, keeping the surface of the protective transparent glass mirror 7 clean. This results in clearer imaging by the probe 3 and reduces the occurrence of false or missed measurements due to dust obstruction. After the endoscope is used, when subsequent inspection and maintenance are required, rotate the connector 13 outward to disengage it from the inner thread protective sleeve 6. Then rotate the inner thread protective sleeve 6 outward along the outer thread sleeve 5 to disengage it from the outer thread sleeve 5, thus removing the inner thread protective sleeve 6 as a whole. The probe 3 can then be inspected. This device makes the overall installation and disassembly of the inner thread protective sleeve 6 relatively simple, facilitating timely inspection and maintenance of the probe 3. The limiting plate 4 limits the installation of the inner thread protective sleeve 6.
