Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a nondestructive detection device for concrete structures. Background Art

[0002] The concrete ultrasonic detector is a device used for non-destructive testing of concrete. Due to the presence of steel bars, the electromagnetic field formed by the detector is affected, causing an induced current to be generated in the coil. After the induced current is amplified, it drives the display instrument to give the test results.

[0003] For example, a Chinese patent with publication number CN218239912U discloses a non-destructive ultrasonic detection device for structural concrete, including an ultrasonic detector body, a protective frame fixedly connected to the top of the ultrasonic detector body, a positioning block fixedly connected to the rear side of the protective frame, a movable block slidably connected to the inner cavity of the positioning block, the top of the movable block penetrates to the outside of the positioning block and is fixedly connected to a connecting block, the front surface of the connecting block is rotatably connected to a protective cover via a rotating shaft, and slots are provided on both sides of the top of the protective frame. A cavity is provided inside, and the number of the cavities is two. A guide groove is provided on the front and rear sides of the inner cavity of the cavity. A guide block is slidably connected to the inner cavity of the guide groove. A transmission block is fixedly connected to one side of the guide block. A limiting column is connected to the bottom of the left side of the inner cavity of the cavity. A wedge block is slidably connected to the surface of the limiting column. A spring 1 is fixedly connected to the right side of the wedge block. One end of the spring 1 away from the wedge block is fixedly connected to the inner wall of the cavity. A hook is fixedly connected to the bottom of the wedge block. The bottom of the hook passes through the inner cavity of the slot.
