Description

Technical Field

[0001] This application relates to the field of water conservancy project quality testing technology, and more specifically, to a water conservancy project crack detection device. Background Technology

[0002] After a period of use, concrete dams in water conservancy projects often develop cracks. To detect these cracks and determine the extent of damage, ultrasonic crack detectors are needed. The basic principle of ultrasonic crack detection is based on the physical phenomena of reflection, refraction, and diffraction that occur when ultrasonic waves encounter cracks in concrete, leading to a prolonged propagation time. By measuring the change in propagation time, the depth and width of the crack can be estimated. Currently, existing ultrasonic crack detectors typically require one hand to hold the device while the other hand holds the probe and moves it along the crack surface. This process is slow, and when the concrete dam is sloping, the hands cannot be separated, increasing the workload for the inspector and making the device inconvenient and inefficient. Therefore, we propose a crack detection device for water conservancy projects. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a crack detection device for water conservancy projects, which solves the technical problems in the background art mentioned above. It realizes a hand-push device composed of a telescopic rod, large rollers and a leveling frame. Different people can use it by hand at different angles. The small rollers at both ends of the horizontal plate will always be in contact with the ground, so that the detection probe can be kept in a relatively vertical state with respect to the ground. Thus, ultrasonic crack detection and treatment can be achieved by using an ultrasonic crack detector and detection probe. It is suitable for crack detection and treatment on the plane and slope of dam body. It is convenient to use, has good portability, and greatly reduces the labor intensity.

[0007] By adopting the above technical solution, a hand-push device consisting of a telescopic rod, large rollers, and a leveling frame is constructed. The telescopic rod is composed of a sliding guide and a slide rod. The bottom end of the slide rod is fixedly connected to a rotating shaft and an L-shaped plate. The large rollers are installed by rotating the rotating shaft, allowing it to be pushed by hand. The L-shaped plate is mounted on a horizontal plate by rotating the shaft. Small rollers are mounted on both ends of the horizontal plate by rotating the shaft. When used by personnel, the small rollers at both ends of the horizontal plate will always be in contact with the ground, so that the detection probe installed on the limiting ring can remain relatively perpendicular to the ground. Thus, the ultrasonic crack detector achieves ultrasonic crack detection and treatment by electrically connecting the detection probe through the wire. Different personnel can use the telescopic rod by holding it at different angles, and it can be moved along the gentle concrete dam body of water conservancy projects. It is suitable for detecting and treating cracks on the plane and slope of the dam body.

[0011] By adopting the above technical solution and setting a handle with an L-shaped structure, it is convenient for people to hold and push the device.

[0012] Optionally, the device base includes a hinge seat, which is fixedly sleeved on the outside of the guide tube. A rotating rod is fixedly mounted on the hinge seat. A convex hollow box is rotatably mounted on the hinge seat through the rotating rod. An ultrasonic crack detector is placed and installed inside the convex hollow box. A limiting block is installed at each of the four corners of the convex hollow box by bolt threads. The limiting blocks press against the upper surface of the ultrasonic crack detector.

[0013] By adopting the above technical solution, the ultrasonic crack detector is installed in a convex hollow box and is limited by four limiting blocks. The convex hollow box can be rotated and adjusted along the rotating rod to adjust the ultrasonic crack detector installed in the convex hollow box to an appropriate angle for easy observation and operation.

[0014] Optionally, one end of the rotating rod is threaded and a lock nut is installed in the thread. The lock nut rotates along the rotating rod and tightly presses against the convex hollow box.

[0015] By adopting the above technical solution, after the ultrasonic crack detector is adjusted to an appropriate angle as the convex hollow box rotates along the rotating rod, the locking nut is tightened to make the convex hollow box press tightly, thereby limiting and fixing the convex hollow box.
