Technical Field

[0001] The utility model relates to a nondestructive detector, in particular to a nondestructive detector with an anti-fall function. Background Art

[0002] Nondestructive testing, also known as non-destructive flaw detection, is a technology that uses X-ray, ultrasonic, infrared, electromagnetic and other principles and technologies combined with instruments to detect defects, chemical and physical parameters of materials, parts and equipment without damaging or affecting the performance of the object being tested. It is a technical operation that obtains internal defect information without damaging the surface of the workpiece or affecting the service life of the workpiece. Traditionally, there are five conventional methods in nondestructive testing, namely X-ray testing RT, ultrasonic testing UT, magnetic particle testing MT, penetration testing PT and eddy current testing ECT.

[0003] The non-destructive detector adopts the ultrasonic detection UT method. It can quickly and accurately detect the location, direction, depth of underground water pipes, metal pipes, cables, etc. and the location and size of the damaged points of the anti-corrosion layer of steel pipes without destroying the ground cover. It is suitable for water companies, gas companies, railway communications, municipal construction, etc.

Although the above patent can support both sides of the body by setting arc rods and inclined rods so that the body is always perpendicular to the pipeline, when the body is placed on the surface of the pipeline and the arc rod is unfolded, the staff's hands may leave the body, and the body itself has a certain weight and will slide along the curved surface of the pipeline, and it is easy to slide off the pipeline and fall, thereby causing damage.

[0005] Therefore, there is a particular need for a non-destructive detector with an anti-fall function to solve the problems existing in the prior art. Utility Model Content

The mounting frame is installed on the upper part of the detector body, and the controller is installed on the upper part of the mounting frame. The controller is electrically connected to the detector body and the fan.

[0021] Embodiment: A nondestructive detector with anti-fall function, see Figure 1-Figure 4 As shown, it includes a detector body 1, a handle 2, a guide rod 5, an anti-fall plate 3, a spring 4, a support leg 11, a protection pad 9, an anti-fall fence 10 and a hanging rope 12. The upper part of the detector body 1 is connected to a handle 2 for assisting holding. The detector body 1 is connected to at least two guide rods 5 distributed on the left and right. The anti-fall plate 3 is slidably connected between the two guide rods 5 on the same side. The front and rear sides of the anti-fall plate 3 are longer than the detector body 1. The guide rod 5 is provided with a spring 4 for buffering and auxiliary resetting. The two ends of the spring 4 are respectively connected to the anti-fall plate 3 and the detector body 1. The lower parts of the two anti-fall plates 3 are connected with support legs 11 distributed front and back. A rubber sheet is provided on the arc surface of the support leg 11. The bottom of the detector body 1 is connected to a protection pad 9, the front part of the detector body 1 is connected to an anti-fall fence 10 for protection, and the rear of the handle 2 is connected to a hanging rope 12 for assisting carrying. The hanging rope 12 is made of synthetic fiber material, and the anti-fall plate 3 contacts the ground to squeeze the spring 4, so that the spring 4 is deformed for buffering.

[0022] See also Figure 4As shown, a fan 7, a protective net 6 and a heat sink 8 are also included. The upper part of the detector body 1 is connected to the fan 7 for heat dissipation by means of bolts. A ventilating hole is opened on the upper part of the detector body 1 to align with the fan 7. The fan 7 is connected to the protective net 6 for protection. The lower part of the detector body 1 is connected to the heat sink 8 for absorbing heat by means of bolts. The heat inside the detector body 1 is discharged by the rotation of the fan 7.

[0023] See also Figure 1 , Figure 2 and Figure 4 As shown, it also includes a mounting bracket 1301 and a controller 13. The mounting bracket 1301 is installed on the upper part of the detector body 1, and the controller 13 is installed on the upper part of the mounting bracket 1301. The controller 13 is electrically connected to the detector body 1 and the fan 7.

[0024] First, the staff member holds the hanging rope 12 with his hand to lift the detector body 1, and carries the detector body 1 to the detection location. Then, the staff member holds the handle 2 to hold the detector body 1, and places the detector body 1 on the pipeline so that the supporting legs 11 are in contact with the pipeline surface. Then, the detector body 1 is started by the controller 13 to run and detect the pipeline surface. During the detection, the staff member holds the handle 2 and continuously pulls the detector body 1 along the direction of the pipeline, thereby performing a comprehensive detection of the pipeline. During the detection process, the detector body 1 will emit heat during operation. The staff member starts the fan 7 through the controller 13, and the fan 7 rotates to blow wind to The detector body 1 is mounted on the detector body 1, thereby cooling the detector body 1 to prevent the detector body 1 from being overheated. At the same time, the heat sink 8 absorbs the heat emitted from the bottom of the detector body 1, thereby accelerating the heat dissipation speed of the detector body 1. When the fan 7 rotates, the protective net 6 plays a protective role to prevent foreign objects from being drawn into the fan 7. When the detector body 1 falls from the pipe, the anti-fall plate 3 is in contact with the ground in advance and is squeezed inward, and the spring 4 is compressed accordingly, thereby playing a buffering role, thereby reducing the impact force on the detector body 1 and preventing the detector body 1 from being damaged. At the same time, the anti-fall fence 10 protects the front of the detector body 1.
