Description

Technical Field

[0001] This application relates to the field of flaw detection technology, and in particular to an airborne penetrant testing device with embedded black light irradiation in four walls. Background Technology

[0002] Penetrant testing is a non-destructive testing method based on capillary action, used to detect discontinuities from openings to surfaces in non-porous metallic or non-metallic materials. The principle involves applying a penetrant containing dye to the surface of the object being tested. If a discontinuity exists, the penetrant will penetrate into the discontinuity due to capillary action. Excess penetrant on the surface is removed, and a developer is applied. The penetrant in the discontinuity is then drawn out, forming a visible pattern. In aviation maintenance, penetrant testing is widely used in civil aviation maintenance (overhaul and refurbishment). In the overhaul of aircraft components and in aircraft structures, penetrant testing is an effective method for detecting fatigue cracks.

[0003] Currently, traditional ceiling-mounted or handheld black light lamps are still commonly used in aviation penetrant testing. If fluorescent penetrant testing is used, the black light intensity for observing the washing effect on the workpiece surface during water washing is generally no less than 300 μW / cm. However, the traditional ceiling-mounted or handheld black light lamps currently used cannot provide omnidirectional black light illumination to the workpiece surface within the tank, cannot effectively guarantee the black light intensity of the inspected workpiece surface, and cannot evenly illuminate each workpiece surface. This easily leads to over-washing or under-washing, reducing the reliability of penetrant testing and potentially causing missed detections, thus jeopardizing aviation safety. Summary of the Invention

[0004] Based on this, it is necessary to address the problem of over-washing or under-washing by providing an aviation penetrant testing device with four-wall embedded black light irradiation, comprising: a housing, a storage structure, and a black light irradiation element. The housing has a top opening, an internal cavity, and a top cover. The storage structure is located inside the cavity and is used to place the item to be tested. A movable structure is located at the bottom of the storage structure, which is used to move the storage structure relative to the housing by raising, lowering, and rotating it. The black light irradiation element is located inside the cavity and surrounds the storage structure circumferentially.

[0005] In one embodiment, the housing and the top cover are hinged together.

[0006] In one embodiment, the housing is provided with a first ear plate, the top cover is provided with a second ear plate, the first ear plate and the second ear plate are connected by a pin, and an automatic opening and closing component is provided between the first ear plate and the second ear plate, the automatic opening and closing component is used to control the automatic opening and closing of the housing and the top cover.

[0007] In one embodiment, the top of the housing is provided with a stepped structure.

[0008] In one embodiment, an operation panel is provided on the outside of the housing. The operation panel is electrically connected to the automatic opening and closing component, the black light irradiation element, and the moving structure. The operation panel is used to open and close the top cover, switch the black light irradiation element on and off, and control the moving structure to rise, fall, and rotate.

[0009] In one embodiment, the exterior of the housing has a through hole, and the interior of the housing includes an electrical conduit and a drain pipe, with the internal electrical conduit and drain pipe extending out of the housing through the through hole.

[0010] In one embodiment, the movable structure includes a lift and a rotating hub. The rotating hub is disposed above the lift, and the lift is controlled to the placement structure via the rotating hub to control the placement structure to rise or fall. The rotating hub is controlled to the placement structure to control the rotation of the placement structure.

[0011] In one embodiment, there are at least four black light illuminating elements, and the at least four black light illuminating elements are arranged around the placement structure.

[0012] In one embodiment, the inner wall of the housing cavity and the inner wall of the top cover are provided with a refractive panel for refracting the black light emitted by the black light irradiation element.

[0013] In one embodiment, the black light illuminating element is a black light lamp.

[0035] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the internal structure of a housing 1000 according to an embodiment of this application. The aviation penetrant testing four-wall embedded black light irradiation device provided in this embodiment includes a housing 1000, a storage structure 1100, and a black light irradiation element 1200. The housing 1000 has a top opening, an internal cavity, and a top cover 2000. The storage structure 1100 is disposed inside the cavity and is used to place the item to be tested. A movable structure is provided at the bottom of the storage structure 1100, which is used to drive the storage structure 1100 to rise, fall, and rotate relative to the housing 1000. The black light irradiation element 1200 is disposed inside the cavity and circumferentially surrounds the storage structure 1100.

[0036] In this embodiment, the top of the housing 1000 has a top opening, and the inner wall of the housing 1000 forms a cavity structure, which serves as a receiving cavity. During penetrant testing, the component to be tested is placed into the receiving cavity inside the housing 1000 through the top opening. After the test is completed, the component to be tested is removed from the receiving cavity inside the housing 1000 through the top opening. A top cover 2000 is provided at the top opening of the housing 1000. The top cover 2000 is used to close the top opening of the housing 1000, making the receiving cavity inside the housing 1000 a sealed cavity. During penetrant testing, after the component to be tested is placed inside the receiving cavity inside the housing 1000, the top cover 2000 covers the top opening of the housing 1000, thus closing the top opening of the housing 1000. This prevents external conditions from interfering with the penetrant testing inside the receiving cavity, improving the reliability and accuracy of the penetrant testing.

[0037] In this embodiment, the housing 1000 has a storage structure 1100 inside its accommodating cavity. The storage structure 1100 is located at the center of the bottom of the accommodating cavity and is used to place the component to be tested. The storage structure 1100 is cylindrical in shape, with a hollow interior forming a cleaning tank, which prevents the bottom from being unable to be cleaned when cleaning the component to be tested. A movable structure is provided at the bottom of the storage platform. The movable structure is connected to a power component to provide power to the movable structure. The movable structure is connected to the storage platform and can drive the storage structure 1100 to rise, fall, and rotate. During the rising, falling, and rotating process, the storage platform can drive the component to be tested on the storage platform to rise, fall, and rotate.

[0038] In this embodiment, a black light irradiation element 1200 is also provided inside the housing 1000. The black light irradiation element 1200 is disposed on the inner wall surface of the housing 1000 for irradiating with black light. The black light irradiation element 1200 is disposed around the storage structure 1100, so that the black light irradiation element 1200 can irradiate the component to be tested placed on the storage platform without blind spots. At the same time, since the storage platform can move up, down and rotate, the black light irradiation element 1200 can fully irradiate the component to be tested, effectively ensuring the black light intensity on the surface of the component to be tested, and evenly irradiating each surface of the component to be tested, avoiding over-cleaning or under-cleaning, improving the reliability of penetrant testing, avoiding the possibility of missed detection, and ensuring aviation safety. Optionally, the selection of the black light irradiation element 1200 inside the housing 1000 is not specifically limited, and can be any black light irradiation element 1200 with waterproof performance and capable of meeting the black light irradiation intensity of each surface of the component to be tested in penetrant testing. Since the black light irradiation element 1200 is waterproof, the component to be tested can be cleaned inside the housing 1000 without damaging the black light irradiation element 1200.

[0039] In this embodiment, the component to be tested is placed into the receiving cavity inside the housing 1000 through the opening at the top of the housing 1000, and fixed on the storage structure 1100. Then, the top cover 2000 is closed, creating a sealed space inside the housing 1000. The black light irradiation element 1200 is turned on, and the black light irradiation element 1200 irradiates the component to be tested with black light. At the same time, the moving structure drives the storage structure 1100 to rise, fall, and rotate. The component to be tested on the storage structure 1100 rises, falls, and rotates accordingly, thereby ensuring that the black light irradiation element 1200 fully irradiates each surface of the component to be tested.

[0040] In one embodiment, the housing 1000 and the top cover 2000 are hinged together. In this embodiment, the hinged connection between the housing 1000 and the top cover 2000 is an openable connection. The top cover 2000 is disposed on the top of the housing 1000 and connected to the rear wall of the housing 1000, so that when the top cover 2000 is opened, it can be fixed above the rear wall of the housing 1000. When the top cover 2000 is closed, it covers the top of the housing 1000 through its connection with the rear wall of the housing 1000, sealing the internal accommodating cavity of the housing 1000.

[0041] In one embodiment, the housing 1000 is provided with a first ear plate 1500, and the top cover 2000 is provided with a second ear plate 2100. The first ear plate 1500 and the second ear plate 2100 are connected by a pin 1600. An automatic opening and closing component is provided between the first ear plate 1500 and the second ear plate 2100. The automatic opening and closing component is used to control the automatic opening and closing of the housing 1000 and the top cover 2000.

[0042] In this embodiment, a first ear plate 1500 is provided on the upper part of the rear wall of the housing 1000, and a second ear plate 2100 is provided on one side of the top cover 2000. The number of the first ear plate 1500 and the second ear plate 2100 is not specifically limited and can be any number that can be stably connected, such as 2, 4, or 6. The first ear plate 1500 and the second ear plate 2100 are alternately arranged so that when the housing 1000 and the top cover 2000 are assembled, the first ear plate 1500 can precisely fit into the gap between the second ear plate 2100. After the 00 is successfully engaged, the pin 1600 is inserted into the first ear plate 1500 and the second ear plate 2100, so that the first ear plate 1500 and the second ear plate 2100 are rotatably connected, thereby enabling the box body 1000 and the top cover 2000 to be connected in an openable and closable manner. At the same time, an automatic opening and closing component is provided at the first ear plate 1500 and the second ear plate 2100 to control the relative rotation between the first ear plate 1500 and the second ear plate 2100. The opening and closing of the box body 1000 and the top cover 2000 is controlled by the relative rotation between the first ear plate 1500 and the second ear plate 2100.

[0043] In one embodiment, the top of the housing 1000 is provided with a stepped structure. In this embodiment, the stepped structure at the top opening of the housing 1000 significantly reduces the blocking effect of the internal thickness of the housing 1000 on the black light reflected from the inner wall of the top cover 2000, effectively improving the intensity of black light irradiation on the component to be tested.

[0044] In one embodiment, an operation panel 1300 is provided on the outside of the housing 1000. The operation panel 1300 is connected to the automatic opening and closing component, the black light irradiation element 1200 and the moving structure. The operation panel 1300 is used to open and close the top cover 2000, turn the black light irradiation element 1200 on and off, and control the moving structure to rise, fall and rotate.

[0045] In this embodiment, a circuit is provided inside the housing 1000. One end of the circuit is connected to an operation panel 1300 disposed on the outer wall of the housing 1000, and the other end is connected to a black light irradiation element 1200, an automatic opening and closing component, and a moving structure, respectively. This allows the operation panel 1300 to be electrically connected to the black light irradiation element 1200, the automatic opening and closing component, and the moving structure, thereby enabling the operation panel 1300 to control the on / off state of the black light irradiation element 1200, the opening and closing state of the automatic opening and closing component, and the movement mode of the moving structure. During the penetrant testing process, the user controls the automatic opening and closing mechanism via the operation panel 1300 to open the top cover 2000, places the component to be tested into the receiving cavity inside the housing 1000, and waits for the component to be tested to be placed stably. Then, the user controls the automatic opening and closing mechanism via the operation panel 1300 to close the top cover 2000. Afterward, the user turns on the black light irradiation element 1200 via the operation panel 1300, allowing the black light irradiation element 1200 to irradiate the component to be tested. At the same time, the user can also control the moving structure via the operation panel 1300 to move the component to be tested on the placement structure 1100 by raising, lowering, and rotating it, so that the black light can fully irradiate any surface of the component to be tested. After the penetrant testing is completed, the user controls the moving structure via the operation panel 1300 to reset the placement structure 1100, then controls the black light irradiation element 1200 to turn off the black light irradiation via the operation panel 1300, and finally controls the automatic opening and closing mechanism via the operation panel 1300 to open the top cover 2000 and remove the component to be tested.

[0046] In one embodiment, the outer side of the housing 1000 has a through hole 1400. The interior of the housing 1000 includes a circuit pipe for providing power and a drain pipe for drainage. The circuit pipe and drain pipe inside the housing 1000 extend out of the housing 1000 through the through hole 1400. In this embodiment, one side of the housing 1000 has a through hole 1400 connecting the inside and outside of the housing 1000. The circuit pipe and drain pipe inside the housing 1000 extend out of the housing 1000 through the through hole 1400, allowing liquid used for cleaning the components to be tested in the internal cavity of the housing 1000 to be discharged from the housing 1000 through the drain pipe. At the same time, wires are connected through the circuit pipes, connecting the automatic opening and closing mechanism, the black light irradiation element 1200, the moving structure, and the operation panel 1300 inside the housing 1000 to provide power.

[0047] In one embodiment, the movable structure includes a lift 1110 and a rotating hub 1120. The rotating hub 1120 is disposed above the lift 1110. The lift 1110 is controlled to the storage structure 1100 through the rotating hub 1120 to control the storage structure 1100 to rise or fall. The rotating hub 1120 is controlled to the storage structure 1100 to control the rotation of the storage structure 1100.

[0048] In this embodiment, the movable structure includes a lifter 1110 for controlling lifting and a rotating hub 1120 for controlling rotation. The lifter 1110 is located at the bottom of the internal accommodating cavity of the housing 1000, and the rotating hub 1120 is located above and connected to the lifter 1110. The storage structure 1100 is located on the rotating hub 1120. Both the lifter 1110 and the rotating hub 1120 are controlled to connect to the storage structure 1100, so that the lifter 1110... 10 can drive the storage structure 1100 to rise and fall, while the rotating hub 1120 can drive the storage structure 1100 to rotate. By controlling the storage structure 1100 through the lifting device 1110 and the rotating hub 1120, the storage structure 1100 can rotate 360° and perform limit displacement within the internal accommodating cavity of the box 1000. The limit displacement is defined as the maximum displacement distance that the component under test can rise and fall without colliding with any structure inside the box 1000.

[0049] In one embodiment, at least four black light irradiation elements 1200 are arranged around the perimeter of the storage structure 1100. In this embodiment, since the black light irradiation elements 1200 are arranged around the perimeter of the storage structure 1100, a minimum of four black light irradiation elements 1200 are required, respectively disposed on the four inner wall surfaces inside the housing 1000, so that the four black light irradiation elements 1200 can irradiate the component to be tested on the storage structure 1100 from four directions. Optionally, the number of black light irradiation elements 1200 is not specifically limited and can be any number capable of fully irradiating the component to be tested on the storage structure 1100, such as 4, 8, or 12.

[0050] In one embodiment, the inner wall surfaces of the housing 1000 and the top cover 2000 are provided with refractive panels to refract the black light emitted by the black light irradiation element 1200. In this embodiment, both the inner wall surfaces of the housing 1000 and the top cover 2000 are provided with refractive panels, so that after the housing 1000 and the top cover 2000 are closed, the inner walls of the enclosed cavity are all refractive panels. The refractive panels are used to refract the black light emitted by the black light irradiation element 1200. This structure allows the black light emitted by the black light irradiation element 1200 to be refracted at multiple angles after passing through the refractive panels on the inner wall surfaces of the housing 1000 and the top cover 2000 during penetrant testing, thereby forming a comprehensive, multi-angle, and blind-spot-free black light irradiation of the component to be tested.

[0051] In one embodiment, the black light irradiation element 1200 is a black light lamp. In this embodiment, the black light irradiation is selected from black light lamps, wherein the black light lamp is selected such that the black light intensity irradiating the surface of the component to be tested is not less than 300 μW / cm.

[0052] Penetrant testing is a non-destructive testing method based on capillary action, used to detect discontinuities from openings to surfaces in non-porous metallic or non-metallic materials. The principle involves applying a penetrant containing dye to the surface of the object being tested. If a discontinuity exists, the penetrant will penetrate into the discontinuity due to capillary action. After removing excess penetrant from the surface and applying a developer, the penetrant within the discontinuity is drawn out, forming a visible pattern. During penetrant testing, excess penetrant on the surface of the part must be removed, while the penetrant that has penetrated into the defect should remain within the defect and not be washed away. Water-washable penetrants are removed directly with water; post-emulsified penetrants require emulsification before water removal; solvent-removable penetrants are wiped off with organic solvents. To monitor the effectiveness of water washing, it should be performed under black light to prevent over- or under-washing. If fluorescent penetrant testing is used, the black light intensity of the workpiece surface during water washing is generally not less than 300 μW / cm. This application installs embedded waterproof black light irradiation elements 1200 around the cleaning tank of the placement structure 1100, and is equipped with a multi-angle refraction panel, which can ensure the black light irradiation of the surface of the inspected workpiece in all directions, effectively prevent over-washing, under-washing and other phenomena, and improve the sensitivity and accuracy of penetrant testing.

[0053] Penetrant testing has a wide range of applications in aircraft component overhaul, such as aircraft hubs, brake assemblies, landing gear assemblies, and flight control components. Parts include engine rotor blades, engine lifting screws, engine stationary blades (guide blades), hub assembly screws, and drive blocks. Using the aerospace penetrant testing four-wall embedded black light irradiation device provided in this application, the black light irradiation of the inspected workpiece surface can be guaranteed from all angles, effectively preventing over- or under-cleaning and improving the sensitivity and accuracy of penetrant testing. This not only significantly improves actual work efficiency but also saves labor costs, shortens testing time, and reduces production costs for enterprises. Furthermore, since the workpieces subjected to penetrant testing are mostly important aerospace components, their reliability and stability are related to the overall airworthiness of the aircraft; improving the accuracy of testing will more effectively guarantee aviation safety.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
