Description

Technical Field

[0001] The utility model relates to the technical field of acoustic detection, in particular to a device for locating a position of pipeline liquid leakage by utilizing the acoustic detection technology. Background Art

[0002] Acoustic detection technology is a technology that uses the propagation characteristics of sound waves to detect, analyze and identify objects or environmental conditions. Ultrasonic flaw detection is a method of inspecting part defects by using the characteristics that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe to the inside of the metal, reflected waves are generated when it encounters defects and the bottom of the part. The location and size of the defect are determined based on these waveforms.

[0003] In the prior art, when an ultrasonic detection device is used to detect a pipeline, a worker generally holds the ultrasonic detector in one hand and holds the probe of the ultrasonic detector in the other hand to detect the outer surface of the pipeline. However, when the pipeline to be detected is higher than the height of the worker, the worker needs to step on a ladder to increase the height so that the probe can contact the outer surface of the pipeline for detection. When it is necessary to detect different positions of the pipeline, the worker needs to first get off the ladder and then adjust the position of the ladder. The worker then steps on the ladder and detects the pipeline again. The detection is relatively cumbersome. During the detection, the ladder may topple over, which may easily injure the worker.

[0004] Therefore, in order to solve the above problems, a device for locating the position of pipeline liquid leakage using acoustic detection technology is provided. Utility Model Content

[0008] Furthermore, the connecting block comprises an upper clamping block, a lower clamping block is mounted on the lower surface of the upper clamping block, and sliding grooves are provided on the outer surfaces of the baffle plate and the frame, and connecting blocks are slidably connected inside the sliding grooves.

[0009] Furthermore, the inner surface of the frame is rotatably connected to a bidirectional screw, the outer surface of the bidirectional screw is threadedly connected to a lower block, one end of the bidirectional screw passes through the frame and is installed with a driven wheel, a driving motor is installed on the lower surface of the frame, and a driving wheel is installed at the output end of the driving motor, and the driving wheel is connected to the driven wheel through a belt.

[0010] Furthermore, a mounting groove is provided on the upper surface of the baffle, a spring is installed on the inner surface of the mounting groove, a slide is installed on the other end of the spring, a limiting rod is installed on the other end of the slide, a limiting hole is provided on the inner surface of the frame, one end of the limiting rod passes through the baffle and is installed inside the limiting hole.

[0011] Furthermore, a sealing plate is installed on the upper surface of the baffle, a through opening is opened on the upper surface of the sealing plate, and a shifting block is provided on the upper surface of the slide plate, and the shifting block is slidably connected inside the through opening.

[0012] Furthermore, the inner surface of the clamping plate is provided with anti-slip stripes.

[0013] The utility model has the following beneficial effects:

[0014] (1) The utility model places the probe of the ultrasonic detector on the upper surface of the lower clamping block, and then cooperates with the upper clamping block to install the lower clamping block, thereby fixing the probe position. After the probe position is fixed, the baffle is placed directly above the frame, and the slider is pushed to slide in the installation groove, the spring gradually contracts, and the limit rod gradually retracts into the frame. When the outer surface of the limit rod is flush with the outer surface of the frame, the baffle is placed on the upper surface of the bottom plate, and then the force on the slider is canceled, so that the spring recovers its elasticity and pushes the slider to reset. At the same time, the limit rod is cooperated and installed in the limit hole, thereby completing the limit of the connection block position. After that, the clamping plate is fixed on the outer surface of the pipeline, and the probe of the ultrasonic detector contacts the outer surface of the pipeline. By starting the driving motor, the output end of the driving motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel and the bidirectional screw to rotate through the belt, so that the connection block moves along the axial direction on the bidirectional screw, thereby facilitating the ultrasonic detector probe to detect different positions of the pipeline, achieving a better detection effect.
