[0002] Crack detection is a technology used to identify and evaluate cracks or fissures on the surface of an object. This technology is often used in industry, construction, materials science and other fields. After concrete has been subjected to heavy loads for a long time, small cracks will appear on the surface. The presence of deeper or wider cracks will affect the safety and normal use of the structure. Therefore, it is necessary to detect the cracks to determine whether the cracks need to be repaired urgently.

In specific implementation, through the magnetic attraction of the first magnetic block 8 and the second magnetic block 10, the fixed suction cup 11 is inserted into or removed from the fixing ring 7 with the help of the fixing column 9, thereby realizing the rapid disassembly and assembly of the fixed suction cup 11 on the collection module 3. When detection work is required, the fixed suction cup 11 is installed on the collection module 3 to assist in fixing the concrete wall. like Figure 4 、 Figure 5 As shown, in this embodiment, a rotating groove 12 is provided inside the acquisition module 3, and the rotating groove 12 is rotatably connected to a rotating column 13, and the rotating column 13 is fixedly connected to a rotating block 14, and a telescopic rod 15 is fixedly connected to the bottom of the rotating block 14 (the structure of the telescopic rod 15 is similar to the telescopic rod 15 structure on the mobile phone selfie stick in the prior art. It is a prior art and is not described in detail or shown in the figures). A handheld handle 16 is provided at the bottom end of the telescopic rod 15, and the acquisition module 3 and the camera 6 are configured to be handheld, retractable and height-adjustable. When it is necessary to test cracks at a higher position, the camera 6 on the acquisition module 3 is adjusted by the telescopic rod 15 to move to a high detection point, so that the device can detect cracks at a high position and improve the detection working range of the device. In specific implementation, the telescopic length of the telescopic rod 15 is adjusted to an appropriate length, and the handheld handle 16 is held together with the telescopic rod 15 to move the acquisition module 3 to the point to be tested, and the camera 6 is close to the concrete wall to perform crack detection.

When it is necessary to control the telescopic rod 15 to rotate out or into the rotating groove 12, the drive motor 20 is turned on to control the drive rod 19 to rotate, thereby driving the driving gear 21 to rotate. The rotation of the driving gear 21 drives the driven gear 22 and the transmission rod 23 to rotate. The transmission rod 23 drives the rotating column 13 to rotate so that the telescopic rod 15 rotates, thereby rotating it out and into the rotating groove 12, which is convenient for subsequent detection of high cracks.

[0022] As a preferred embodiment of the present invention, preferably, Figure 1As shown, a group of hanging rods 26 are provided on the top of the left and right sides of the detection box 1, and a group of hanging rods 26 are provided with hanging belts 27. The hanging belts 27 enable the staff to quickly carry the entire detection box 1 by means of a shoulder strap or a hanging belt, which is convenient for crack detection of any concrete wall at the construction site.

[0023] As a preferred embodiment of the present invention, preferably, Figure 1 As shown, a pair of fixed side panels 28 are provided on the surface of the detection box 1 below one set of hanging rods 26, and a fixed bottom panel 29 is provided below the fixed side panels 28. The fixed space formed by the fixed side panels 28 and the fixed bottom panel 29 enables the collection module 3 to be fixedly clamped on the side wall of the detection box 1 after the work is completed, so as to facilitate the subsequent transportation and carrying of the collection module 3 together with the detection box 1.

[0024] As a preferred embodiment of the present invention, preferably, Figure 2 、 Figure 7 As shown, a cable holder 30 is provided on the surface of the detection box 1 located on one side of the first plug connector 2. A cable hole 31 adapted to the conveyor line 5 is opened inside the cable holder 30, and a cleaning brush 32 is provided on the hole wall of the cable hole 31. By passing the conveyor line 5 through the cable hole 31 in the cable holder 30, the conveyor line 5 can be sorted to avoid entanglement and knotting. In addition, the relative movement of the cleaning brush 32 during the passing process can wipe off dust on the surface of the conveyor line 5.

[0025] As a preferred embodiment of the present invention, preferably, Figure 1 As shown, a display screen 33 is provided in the middle of the front end of the detection box 1, and a number of control buttons 34 are equidistantly provided on the surface of the detection box 1 below the display screen 33. The display screen 33 can be turned on and off by the control buttons 34. Specifically, other operations can be set according to the functions of the control buttons 34. The display screen 33 can reflect the detection data of the crack width detected by the device and the data feedback results in real time.

[0026] As a preferred embodiment of the present invention, preferably, Figure 1 、 Figure 2 As shown, buffer pads 35 are provided at the four corners of the rear end of the detection box 1. The buffer pads 35 are made of rubber material. A number of heat dissipation grilles 36 are equidistantly provided in the middle of the rear end of the detection box 1. In specific implementation, the setting of the buffer pads 35 can provide buffering protection (when the detection box 1 is placed flat on the work surface for operation), and can prevent the outer wall of the detection box 1 from directly contacting the work surface, reducing the wear between the two and increasing the working service life. The heat dissipation grilles 36 can improve the heat dissipation performance of the detection box 1 during operation, and prevent the hot gas generated by the operation of the inner cavity from being excessively retained in the box.

[0027] Working principle: As shown in the accompanying drawings Figures 1-7 As shown, first, the first plug connector 2 and the second plug connector 4 are respectively inserted into the two ends of the conveyor line 5 (the specific length can be selected according to the situation) to achieve the docking installation between the collection module 3 and the detection box 1. Then, the control button 34 is used to open the detection box 1. The staff holds the collection module 3 so that the camera 6 is close to the concrete wall to capture the crack depth and overall crack working conditions, so as to perform subsequent crack detection and crack depth analysis. During the detection process, the fixed suction cup 11 is close to the concrete wall for adsorption and fixation to perform auxiliary work. When crack detection is required on a higher concrete wall, the drive motor 20 is turned on to rotate the telescopic rod 15 out of the rotating slot 12. The telescopic rod 15 is then manually adjusted to an appropriate length. The collection module 3 is then held by the hand grip 16, and the camera 6 is then placed at the detection point for crack detection. After the device is completed, the fixed suction cup 11 can be pulled out of the fixing ring 7. When detection is required, the fixed suction cup 11 and the fixing column 9 are reinserted into the fixing ring 7 using the magnetic attraction between the first magnetic block 8 and the second magnetic block 10.

[0028] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
