Description

Technical Field

[0001] The utility model provides a C-scan imaging detection device, belonging to the technical field of ultrasonic imaging equipment, and particularly relates to a robot hyperbolic water-jet C-scan imaging detection device. Background Art

[0002] C-scan is a detection method using ultrasonic imaging technology, mainly used for non-destructively detecting internal defects and structural problems of materials. In this technology, ultrasonic waves are sent to the object to be detected through a specific sensor device, and then, according to the propagation and reflection of ultrasonic waves in materials with different densities, high-resolution images are generated to show the details and defects inside the materials. Among them, water serves as the propagation medium of ultrasonic waves, helping to transmit and receive ultrasonic signals, ensuring that it can effectively penetrate and reflect back. Secondly, water also acts as an interface couplant, reducing the energy loss of ultrasonic waves during propagation and improving the clarity and accuracy of imaging. In addition, water can eliminate the air or gas isolation layer, enabling ultrasonic waves to directly contact the object to be detected, thereby producing more reliable imaging results.

[0003] Most of the existing imaging scanning devices for C-scan can only scan flat surfaces and cannot effectively scan devices with similar elliptical convex surfaces such as wings. Moreover, the size of the scanning device is limited, the efficiency of using a single scanning device is low, and it is inconvenient to replace the damaged device, making it inconvenient to use. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the embodiments of the present application provide a robot hyperbolic water-jet C-scan imaging detection device, which solves the problems that the existing ultrasonic scanning imaging devices are inconvenient for curved surface scanning and inconvenient for maintenance.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A robot hyperbolic water-jet C-scan imaging detection device includes a curved surface to be measured, and a plurality of uniformly distributed and mutually movably connected detection structures are sleeved outside the curved surface to be measured. The detection structure includes a housing placed above the curved surface to be measured. The housing is connected with an ultrasonic transmitter placed inside the housing through limiting plates that penetrate through the end plates at both ends of the housing and are symmetrically distributed. A plurality of uniformly distributed balls placed inside the housing are provided at the opening on one side of the housing close to the curved surface to be measured.

[0006] Preferably: A water storage tank is sleeved on the side of the housing away from the curved surface to be measured. A water delivery pipe penetrating through the water storage tank is arranged inside the water storage tank. A drain pipe corresponding to the water delivery pipe is arranged inside the housing, and one end of the drain pipe away from the water delivery pipe corresponds to the balls.

[0007] Preferably, a universal joint is provided on the outer wall at one end of the outer casing, and a card slot corresponding to the universal joint is provided on the outer wall at the other end of the outer casing.

[0008] Preferably, the limiting plate is placed below the universal joint and the card slot, and blocking plates are provided on the upper and lower sides of the limiting plate and inside the outer casing.

[0009] Preferably, an activity slot with a width greater than that of the blocking plate is provided inside the side wall of the outer casing, and a spring is provided inside the activity slot on the side of the limiting plate away from the ultrasonic transmitter.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] In the present utility model, a number of detection structures are provided and distributed around the outside of the curved object to be measured. The detection structures are movably connected to each other through the outer casing, so as to adapt to most curved surfaces with different curvatures. For a hyperbolic structure such as a wing, it can directly surround the outside of it. By moving the combined detection mechanism, multi-directional movement can be achieved with the help of a number of ball bearings, so as to facilitate checking for omissions and filling in the gaps from the imaged parts, avoiding scanning dead angles. The modular structure also facilitates fixed-point fault repair at fixed points and is convenient to use.

[0012] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0026] As Figure 1 and Figure 2 shown, the robot hyperbolic water jet C-scan imaging detection device includes a curved object to be measured 1, and a plurality of uniformly distributed and mutually movably connected detection structures 2 sleeved outside the curved object to be measured 1. The detection structure 2 includes an outer housing 21 placed above the curved object to be measured 1, and a water storage tank 12 sleeved on one side of the outer housing 21 away from the curved object to be measured 1. A water delivery pipe 13 passing through itself is arranged inside the water storage tank 12, a drain pipe 14 corresponding to the water delivery pipe 13 is arranged inside the outer housing 21, one end of the drain pipe 14 away from the water delivery pipe 13 corresponds to the ball 23, the outer housing 21 is connected with an ultrasonic transmitter 11 placed inside the outer housing 21 through limiting plates 22 symmetrically distributed through both end plates of itself, and a plurality of uniformly distributed balls 23 placed inside the outer housing 21 are arranged on the opening on one side of the outer housing 21 close to the curved object to be measured 1.

[0027] In this implementation scheme, by arranging a number of detection structures 2 distributed around the outside of the curved surface object to be measured 1, the detection structures are interconnected through the outer housing 21, so as to adapt to curved surfaces with most different curvatures. For a hyperbolic surface structure such as an aircraft wing, it can directly surround the outside of it. By moving the combined detection mechanism 2, multi-directional movement can be achieved with the help of a number of balls 23, so as to facilitate checking for omissions and deficiencies in the imaged part, avoid scanning dead angles, and the modular structure is also convenient for fixing-point troubleshooting and maintenance, making it easy to use.

[0028] As Figure 3 and Figure 4 shown, a universal joint 24 is provided on the outer wall at one end of the outer housing 21, a card slot 25 corresponding to the universal joint 24 is provided on the outer wall at the other end of the outer housing 21, a limiting plate 22 is placed below the universal joint 24 and the card slot 25, blocking plates 26 are provided on the upper and lower sides of the limiting plate 22 and are located inside the outer housing 21, and an activity slot 27 with a width greater than that of the blocking plate 26 is provided inside the side wall of the outer housing 21. A spring 28 is provided inside the activity slot 27 on the side of the limiting plate 22 away from the ultrasonic transmitter 11.

[0029] In this implementation scheme, the movement of the limiting plate 22 facilitates the installation and disassembly of the ultrasonic transmitter 11; the detection structures 2 in the device are interconnected through the outer housing 21 and can adapt to curved surfaces with a variety of different curvatures. This makes it particularly suitable for hyperbolic surface structures such as aircraft wings, which can directly surround and conduct comprehensive inspections; a number of balls 23 in the device allow the detection structure 2 to achieve multi-directional movement. This design helps to check for omissions and deficiencies in the imaged part and avoid missed inspections due to scanning angle problems. At the same time, the modular structure design makes the device easy to troubleshoot and repair at fixed points, improving the convenience and efficiency of use; a universal joint 24 and a card slot 25 are provided on the outer housing 21, as well as a limiting plate 22, blocking plates 26 and an activity slot 27. The design of these structures makes the installation and disassembly of the ultrasonic transmitter 11 more convenient. A spring 28 is provided on the limiting plate, which helps to stabilize and control the movement of the structure, thereby improving the operation accuracy and stability of the device. These design features make the detection device have strong adaptability and operability in practical applications, and are particularly suitable for high-precision and non-destructive imaging detection of complex curved surface structures, providing an important guarantee for the structural health and safety in the industrial field.
