Description

Technical Field

[0001] The invention relates to the technical field of protective devices, and more specifically to a protective device for a probe of an eddy current flaw detector. Background Art

[0002] Eddy current flaw detector is one of many non-destructive testing methods. It uses the basic theory of "electromagnetism" as the basis for conductor detection. The eddy current flaw detector brings the conductor close to a probe with alternating current. The probe establishes an alternating magnetic field. The alternating magnetic field passes through the conductor and generates electromagnetic induction with it, establishing eddy currents in the conductor. The eddy currents in the conductor will also generate their own magnetic field. The effect of the eddy current magnetic field will also change the strength of the original magnetic field, thereby causing changes in the probe voltage and impedance.

[0003] Among the eddy current flaw detectors we currently use, the probe structure of the equipment is not easy to protect when not in use, so the probe will be worn out from the outside, which will affect the accuracy of the equipment.

[0004] Therefore, it is necessary to provide a protective device for an eddy current flaw detector probe to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a protective device for an eddy current flaw detector probe.

[0007] Furthermore, a fixing ring is fixedly connected to the outer side of the bottom of the sealing cylinder, and the main body includes a second set of plates and a first set of plates. The second set of plates and the first set of plates are both provided with placement holes inside, and the tube body is clamped inside the placement hole.

[0022] like Figure 1-4 As shown, the present application provides a protective device for an eddy current flaw detector probe, including a main body 1 and a protective assembly 2. The protective assembly 2 includes a transmission line 201 fixedly connected to the top of the main body 1, a detection block 202 fixedly connected to the bottom of the transmission line 201, a handle 203 fixedly connected to the bottom of the detection block 202, a sealing tube 207 is sleeved on the outer side of the detection block 202, a threaded hole 204 is provided inside the handle 203, a fixing bolt 206 is threadedly connected to the inside of the threaded hole 204, and a sealing box 205 is fixedly connected to the bottom of the fixing bolt 206.

[0023] A fixing ring 208 is fixedly connected to the outer side of the bottom of the sealing cylinder 207. The main body 1 includes a second set of plates 106 and a first set of plates 103. The second set of plates 106 and the first set of plates 103 are both provided with placement holes 105 inside, and the tube body 3 is clamped inside the placement hole 105.

[0024] Support plates 102 are fixedly connected to both sides of the bottom of the main body 1, and the top of one of the support plates 102 is fixedly connected to the bottom of the first set of plates 103. Two fixing holes 104 are provided inside the first set of plates 103. A limiting rod 107 is slidably connected inside the fixing hole 104. A fixing plate 108 is fixedly connected to the other side of the limiting rod 107. One side of the fixing plate 108 is fixedly connected to one side of the second set of plates 106, and one side of the limiting rod 107 is fixedly connected to one side of the second set of plates 106.

[0025] A fixed sleeve 109 is fixedly connected to the top of the support plate 102 , the interior of the fixed sleeve 109 is adapted to the outside of the sealing box 205 , a rotating bar 110 is fixedly connected to one side of the fixed sleeve 109 , and a limiting plate 111 is rotatably connected to the outer side of the rotating bar 110 .

[0026] When the device is in use, first place the device as a whole on the ground, then move the second set of plates 106 through the inside of the fixing hole 104 to one side of the first set of plates 103, and after the second set of plates 106 is moved to the limit position, the fixing sheet 108 touches the outside of the second set of plates 106 to prevent the second set of plates 106 from moving, and then place the entire tube body 3 between the first set of plates 103 and the second set of plates 106 through the placement hole 105, so that the tube body 3 can be stored inside the tube body 3, so that the protective component 2 can detect the inside of the tube body 3 conveniently and improve efficiency;

[0027] After the tube body 3 is placed, the sealing box 205 can be rotated on the outside of the bottom of the sealing cylinder 207, so that the fixing bolt 206 can be taken out from the inside of the threaded hole 204, so that the sealing box 205 can be taken out from the bottom of the detection block 202, and the bottom of the detection block 202 will be exposed to the outside, and then the detection block 202 and the sealing cylinder 207 are brought close to the inside of the tube body 3. At this time, the staff's hand is inserted from the other end of the tube body 3, and the handle 203 is held inside the tube body 3 and moved so that the inside of the tube body 3 can be detected. At the same time, when the detection block 202 enters the inside of the tube body 3, since the diameter of the fixing ring 208 is larger than the diameter of the tube body 3, the detection block 202 will block the sealing cylinder 207 when entering the tube body 3, so that the sealing cylinder 207 will be outside the tube body 3. After the detection of the detection block 202 inside the tube body 3 is completed, the handle 203 is pushed 203 allows the detection block 202 to be taken out from the inside of the tube body 3, and at the same time the sealing tube 207 can be close to the detection block 202 again, so that the sealing tube 207 can continue to protect the detection block 202, and finally the sealing box 205 is connected to the inside of the threaded hole 204 through the fixing bolt 206, so that the sealing box 205 can be reinstalled at the bottom of the sealing tube 207, and the detection block 202 as a whole can continue to be sealed and protected. The last step is to align the sealed detection block 202 with the position of the fixed sleeve 109, and place the detection block 202 together with the sealing box 205 and the sealing tube 207 into the fixed sleeve 109, so that the detection block 202 can be stored outside the device, so as to be easy to carry, and at the same time, the limiting piece 111 is rotated to one side of the sealing box 205 through the rotating bar 110, so that the connection of the sealing box 205 can be fixed, thereby avoiding falling.
