Description

Technical Field

[0001] The present invention relates to the technical field of crack detection, and in particular to crack observation equipment and method with warning prompting functions. Background Art

[0002] Crack depth measurement is an important part of engineering monitoring, especially in the fields of highways, bridges and tunnels. By measuring the reflection or diffraction time of ultrasonic waves at the cracks and combining the propagation speed of ultrasonic waves to calculate the depth of the cracks, non-destructive testing can be achieved without affecting the structure. The measurement accuracy is high and the application range is wide. It can be used to measure the crack depth of various materials. The existing ultrasonic crack depth detection device measurement process requires full manual operation, which is time-consuming and labor-intensive. The existing patent announcement number CN118896572B discloses a multi-angle measurement device for the crack depth of highway bridges and tunnels, in which an ultrasonic detection component is set. During the crack depth measurement process, the ultrasonic detection transducer can be arranged on both sides of the crack. The distance between the ultrasonic detection transducer and the crack is adjusted by the left-right symmetrical movement of the ultrasonic detection transducer, and multiple sets of data are automatically measured, reducing the operation of manually moving the ultrasonic detection transducer.

[0003] However, this detection method still requires manual promotion, so the time and location of the detection will be greatly limited. In addition, the cleaning location is prone to dust that affects the shooting, which is not conducive to improving the quality of the shooting.

The crack observation device with warning function according to claim 5 is characterized in that: The dustproof camera unit comprises a fixing seat (334) fixedly connected to the outer side of the mounting side frame (304); a steering motor is arranged inside the fixing seat (334); the output end of the steering motor is connected to a connecting shaft (333); a camera (331) is fixedly arranged at the end of the connecting shaft (333); a cover (332) is also arranged at the end of the fixing seat (334); a transparent cylinder (310) is rotatably arranged at the outer side of the cover (332); the transparent cylinder (310) is made of transparent plastic; a driven pulley (330) is fixedly arranged at the end of the transparent cylinder (310); a driving pulley (328) is arranged on the transmission rod; the driving pulley (328) and the driven pulley (330) are connected to each other by a transmission belt (329); a wiping positioning rod (335) is fixedly arranged at the lower end of the fixing seat (334); a wiping plate (336) for wiping the surface of the transparent cylinder (310) is arranged at the end of the wiping positioning rod (335).

8. The crack observation device with warning function according to claim 7 is characterized in that: The fixed seat (334) is also provided with a water spray assembly, through which water is sprayed on the surface of the transparent tube (310). A water tank (337) is fixedly provided on the surface of the fixed seat (334), and the water tank (337) is used to store cleaning liquid. The outer side of the wiping plate (336) is connected to a cache box bar (340) through a cross bar. The upper end of the cache box bar (340) is provided with a plurality of nozzles (339) that spray water toward the surface of the transparent tube (310). The liquid inlet end of the cache box bar (340) is connected to a liquid pump inside the water tank (337) through a water pipe (338).

9. The crack observation device with warning function according to claim 1, characterized in that: The flip adjustment member comprises a flip shaft at the center of the mounting base plate (301); a mounting notch (204) is provided on the flying body (100); the end of the flip shaft extends into the mounting notch (204); a flip worm gear (203) is provided on the flip shaft; the upper side of the flip worm gear (203) is meshed with the worm (201); one end of the worm (201) is rotatably connected to a fixed block on the flying body (100); and the other end of the worm (201) is fixedly connected to an output end of a flip motor (202) on the flying body (100).

10. The method for using the crack observation device with warning function according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: driving the flying body (100) to fly along the target area through the flying power component; Step 2: Under the drive of the fine-tuning motor (302), the adjusting screw (318) and the adjusting slider (319) rotate relative to each other. Under the action of the thread, the adjusting slider (319) slides along the surface of the mounting base plate (301), and then cooperates with the shear rod group counterweight (323) to move synchronously with the cleaning member, so that the cleaning position of the cleaning member can be adjusted while ensuring the smoothness of cleaning. The cleaning member cleans the target wall surface, and when wiping, it will suck away the dust generated by the cleaning brush (308) to avoid dust diffusion affecting the shooting; Step 3: When the transmission rod rotates, the driving pulley (328) drives the driven pulley (330) to rotate through the transmission belt (329), and the driven pulley (330) drives the transparent tube (310) to rotate. The wiping plate (336) will wipe the dust on the surface of the transparent tube (310), thereby maintaining the surface of the transparent tube (310) in a clean state to avoid the problem of dust blocking the shooting. When the detection component obtains crack information, the alarm component will send an alarm signal.
