[0002] Traditional methods for detecting concrete cracks mainly rely on manual visual observation and simple measuring tools such as rulers and calipers. These methods have many limitations, such as low detection efficiency, low accuracy, difficulty in detecting tiny cracks, and insufficient accuracy and comprehensiveness in recording details such as the direction and shape of cracks. In addition, manual marking of cracks is prone to errors and is not convenient for subsequent data analysis and processing.

[0003] Meanwhile, the announcement (CN222048819U) discloses a concrete crack detection ruler for construction projects, including a detection ruler body. The detection ruler body includes a length ruler with a cavity. One side of the cavity has a scale line, and the other side has multiple lights. Limiting blocks are provided on both sides of the length ruler. A moving block is provided on the length ruler, and a vertical detection device is provided on the moving block. The vertical detection device includes a support block and a support rod. A support plate is slidably provided on the support rod, and a depth ruler is provided on the support plate. The depth ruler is slidably set on the support block. A traction rope is provided on the length ruler, and a chalk box and marking chalk are provided on the traction rope.

[0004] The aforementioned concrete crack detection ruler for construction projects can only improve the practicality of the main body of the ruler and make simple markings of chalk measurement data. It cannot perform real-time detection. If it encounters water or a surface where chalk cannot be used, it will be unable to record data during use.

A handle 4 is fixedly installed in the middle of the outer rear end face of the fixing device 2. A light 3 is fixedly installed in the middle of the lower front side of the fixing device 2 to provide illumination.

[0031] The measuring ruler body 1 has grooves 7 on both the left and right sides. The grooves 7 have sliding grooves 6 on both the front and back sides.

A second detection head 15 is fixedly provided on the left side of the fixing block 16 to perform detection function, and the second detection head 15 is attached inside the first detection head 8.

[0033] A switch 13 is fixedly installed in the middle of the front side of the upper end face of the length sensor 9, a depth display screen 18 is fixedly installed in the middle of the upper end face of the depth sensor 5, and a switch 13 is fixedly installed on the left side of the upper end face of the depth sensor 5 for control purposes.

[0034] Working principle and process of concrete crack detection marking ruler:

[0035] This concrete crack detection and marking ruler primarily utilizes a length sensor 9, a depth sensor 5, and different detection heads 8 and 15 to measure the length, depth, and width of concrete cracks. It also features illumination for use in various environments and can be flexibly adapted to different detection needs using a multi-layer telescopic device 19. Before use, check that all components of the ruler are intact, including the length sensor 9, depth sensor 5, detection head 8, and detection head 15, and that the length display 12 and depth display 18 are functioning correctly. Then, press the switch 13 located in the middle of the front of the upper end face of the length sensor 9 and the switch 13 located on the left side of the upper end face of the depth sensor 5 to turn on the length sensor 9 and depth sensor 5 respectively. Powering device 5 puts the device into standby mode. Based on the approximate condition of the crack, the length sensor 9 is adjusted appropriately through the adjustment device 11 to ensure that it can accurately measure the crack length. At the same time, based on the estimated crack depth, the multi-layer telescopic device 19 is adjusted so that the sensing head 20 can penetrate into the appropriate position of the crack. The measuring ruler body 1 is placed at one end of the concrete crack, aligning the measuring ruler body 1 with the crack. Holding the handle 4 in the middle of the outer rear end face of the fixing device 2, the measuring ruler is slowly moved along the crack. The length sensor 9 begins to record the distance moved and displays the data on the length display screen 12 in real time. When the measuring ruler moves to the other end of the crack, it stops moving. At this time, the value displayed on the length display screen 12 is the length of the crack. Activate the multi-layer telescopic device 19 to slowly lower the sensing head 20 into the concrete crack. After the sensing head 20 contacts the bottom of the crack, it transmits a signal to the depth sensor 5. The depth sensor 5 processes the signal and displays the crack depth on the depth display screen 18. Then, use the length sensor 9 to control the sliding slider 14 and the slider 17 so that the first detection head 8 and the second detection head 15 are respectively attached to both sides of the crack. Use the adjustment device 11 to adjust the length display screen 12 to the width detection display program. Then, the first detection head 8 and the second detection head 15 will transmit information to the adjusted length display screen 12. If the ambient light is dim, the lighting lamp 3 can be turned on to provide sufficient light for the measurement.
