Description

Technical Field

[0001] This utility model relates to the field of industrial endoscope technology, specifically to an industrial endoscope probe structure. Background Technology

[0002] Industrial endoscopes, as important tools for non-destructive testing, are widely used for visual inspection in complex industrial environments such as pipelines and the interiors of machinery. The cameras mounted on their probes are susceptible to contaminants such as oil, dust, and debris during operation, leading to blurred images or even malfunction, directly impacting inspection accuracy and efficiency. Current technologies often involve manual wiping of the cameras after shutdown; however, frequent shutdowns for cleaning significantly reduce the continuity of inspection operations, affecting efficiency. Traditional cleaning systems often rely on independent drive components (such as motors or hydraulic devices), resulting in complex structures, high maintenance costs, and reliability highly dependent on operating conditions.

[0003] Therefore, there is an urgent need for a compact, easy-to-operate, and highly effective cleaning solution for industrial endoscope probes that can achieve efficient cleaning of the camera through simple control without stopping the machine, in order to meet the needs of harsh industrial environments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an industrial endoscope probe structure. Airflow through the trachea increases the internal pressure, causing deformation of the corrugated section. This deformation, in turn, allows the arc-shaped part to drive the cleaning hood to clean the camera. When airflow is cut off, a torsion spring overcomes the corrugated deformation, causing the cleaning hood to separate and reset. The camera can be repeatedly cleaned by controlling the airflow through the trachea. The cleaning mechanism is simple and compact, allowing cleaning without interrupting endoscope inspection operations. It provides effective cleaning of the camera, meeting the inspection needs of industrial endoscopes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an industrial endoscope probe structure, including a probe body, a camera disposed at the end of the probe body, and a cleaning mechanism disposed outside the camera. The cleaning mechanism includes a support sleeve sleeved on the outside of the probe body, two cleaning covers disposed opposite to each other outside the camera, and an air tube for driving the movement of the cleaning covers. The cleaning covers are connected to the support sleeve, and the side portions of the two air tubes are respectively connected to the cleaning covers. Both ends of the air tubes pass through the support sleeve and are connected to an air source.

[0006] The air tube includes a straight section passing through the support sleeve, an arc-shaped section connected to the cleaning cover, and a corrugated deformable section connecting the straight section and the arc-shaped section. The straight section is connected to an air source.

[0007] The air pipe has an exhaust port in its arc-shaped portion, and the cleaning cover has an air inlet on its edge. The exhaust port is connected to the air inlet. The cleaning cover has a blower for blowing on the camera on its side, and the blower is connected to the air inlet.

[0008] The edge of the cleaning cover is provided with a receiving groove, the air inlet is located in the receiving groove, and the arc-shaped part is sealed to the cleaning cover through the receiving groove.

[0009] The support sleeve has connecting shafts on both sides of its end, and the cleaning cover has connecting sleeves at both ends. The cleaning cover is rotatably mounted on the connecting shafts via the connecting sleeves.

[0010] A torsion spring for separating the two cleaning covers is provided between the connecting sleeve and the connecting shaft, and the torsion spring is sleeved on the outside of the connecting shaft.

[0011] A cleaning cotton pad is provided on the inner side of the cleaning cover, and the blowing hole is provided through the cleaning cotton pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By ventilating through the trachea, the pressure inside the trachea increases, and the corrugated deformation part deforms, thereby causing the arc-shaped part to drive the cleaning cover to clean the camera. When the air in the trachea is cut off, the cleaning cover is separated and reset under the action of the torsion spring to overcome the corrugated deformation part. The camera can be cleaned repeatedly by ventilating and cutting off the air in the trachea. The cleaning mechanism has a simple and compact structure and can be cleaned without interrupting the endoscope's inspection operation. It has a good cleaning effect on the camera.

[0014] (2) By setting an exhaust hole in the arc-shaped part, an air inlet hole communicating with the exhaust hole is set on the cleaning cover, and a blower hole for blowing the camera is set on the side of the cleaning cover. While the cleaning cover is cleaning, the camera is blown, which further improves the cleaning effect of the cleaning structure on the camera. Attached Figure Description

[0021] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] See Figures 1-5 An industrial endoscope probe structure includes a probe body 1, a camera 2 disposed at the end of the probe body 1, and a cleaning mechanism disposed outside the camera 2. The cleaning mechanism includes a support sleeve 3 sleeved on the outside of the probe body 1, two cleaning covers 4 disposed opposite to each other outside the camera 2, and an air tube 5 for driving the movement of the cleaning covers 4. The cleaning covers 4 are connected to the support sleeve 3, and the side portions of the two air tubes 5 are respectively connected to the cleaning covers 4. Both ends of the air tubes 5 pass through the support sleeve 3 and are connected to an air source.

[0023] The air tube 5 includes a straight section 51 passing through the support sleeve 3, an arc-shaped section 52 connected to the cleaning cover 4, and a corrugated deformation section 53 connecting the straight section 51 and the arc-shaped section 52. The straight section 51 is connected to the air source.

[0024] The arc-shaped portion 52 of the air pipe 5 is provided with an exhaust port 521, and the edge of the cleaning cover 4 is provided with an air inlet 42. The exhaust port 521 is connected to the air inlet 42. The side of the cleaning cover 4 is provided with a blower hole 43 for blowing and cleaning the camera 2. The blower hole 43 is connected to the air inlet 42.

[0025] The edge of the cleaning cover 4 is provided with a receiving groove 41, the air inlet 42 is located in the receiving groove 41, and the arc-shaped part 52 is sealed to the cleaning cover 4 through the receiving groove 41.

[0026] The support sleeve 3 has connecting shafts 31 on both sides of its end, and the cleaning cover 4 has connecting sleeves 44 on both ends. The cleaning cover 4 is rotatably mounted on the connecting shafts 31 through the connecting sleeves 44.

[0027] A torsion spring 6 for separating the two cleaning covers 4 is provided between the connecting sleeve 44 and the connecting shaft 31. The torsion spring 6 is sleeved on the outside of the connecting shaft 31.

[0028] A cleaning pad 7 is provided on the inside of the cleaning cover 4, and the blow hole 43 is set through the cleaning pad 7.

[0029] The specific working process of this utility model:

[0030] When the probe is in use, the trachea 5 is not open to air, and the cleaning cover 4 is separated under the action of the torsion spring 6. That is, the two cleaning covers 4 rotate along the connecting shaft 31 to the edge of the support sleeve 3, and the two cleaning covers 4 separate. At this time, the camera 2 of the probe is exposed, and the camera 2 of the probe can be used for detection.

[0031] When the camera 2 at the front end of the probe becomes dirty due to environmental pollution, the air source is activated to inflate the air pipe 5. Under the action of inflation, the pressure inside the air pipe 5 increases, and the corrugated deformation part 53 deforms and expands. This causes the corrugated deformation part 53 to overcome the elastic force of the torsion spring 6 and swing. Through the arc part 52, it drives the two cleaning covers 4 to come together. The cleaning cotton pads 7 on the cleaning covers 4 wipe and clean the contaminants on the surface of the camera 2. At the same time, the gas discharged from the arc part 52 passes through the air inlet 42 and is discharged through the blow hole 43 to further blow the dust on the camera 2, thereby cleaning the camera 2. When the air supply to the air pipe 5 is stopped, the two cleaning covers 4 separate under the action of the torsion spring 6, overcoming the stress deformation of the corrugated deformation part 53, and clean the camera 2 again. By repeatedly opening and closing the air supply to the air pipe 5, the cleaning of the cleaning covers 4 and indirect blowing are achieved.

[0032] By ventilating through the trachea 5, the pressure inside the trachea 5 increases, causing the corrugated deformation part 53 to deform. This causes the arc-shaped part 52 to drive the cleaning cover 4 to clean the camera 2. When the air supply to the trachea 5 is cut off, the cleaning cover 4 separates and resets under the action of the torsion spring 6, overcoming the corrugated deformation part 53. The camera 2 can be cleaned repeatedly by ventilating and cutting off the air supply through the trachea 5. The cleaning mechanism has a simple and compact structure, and can perform cleaning without interrupting the endoscope's inspection operation, resulting in a good cleaning effect on the camera 2.

[0033] By providing an exhaust port 521 in the arc-shaped portion 52, and an air inlet 42 communicating with the exhaust port 521 on the cleaning cover 4, and providing a blower 43 for blowing the camera 2 on the side of the cleaning cover 4, the cleaning structure further improves the cleaning effect of the camera 2 while the cleaning cover 4 is cleaning.

[0034] The design of the corrugated deformation section 53 is based on the principle of pneumatic flexible actuators, a technology widely used in industrial automation. For example, industrial pneumatic clamps employ flexible pneumatic components with a corrugated tube structure. Through inflation, they generate radial or axial deformation to achieve clamping functionality, and precise bending is achieved through air pressure control. The working mechanism of the corrugated deformation section 53 in this application is consistent with the above example: Inflation stage: After air is input, the internal pressure of the corrugated deformation section 53 increases, the corrugated folds unfold, generating axial contraction or radial expansion deformation, thereby driving the arc-shaped section 52 to displace and causing the cleaning cover 4 to close. De-pressurization stage: After the air pressure is released, the corrugated deformation section 53 resets under the action of elastic restoring force (material self-rebound or assisted by the torsion spring 6), and the cleaning cover 4 separates.

[0035] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
