[0036] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0037] See Figures 2 to 3 as shown;

[0038] An eddy current flaw detector device with a transition conduit in this embodiment, the device includes:

[0039] Device integration frame 6;

[0040] Multiple groups of conduits integrated on the device integration frame 6, and the multiple groups of conduits are coaxially arranged; and

[0041] The flaw detector 3 integrated on the device integration frame 6, the flaw detector 3 has an inlet, and the inlet is coaxially arranged with the multiple groups of conduits;

[0042] A plurality of sets of conduits sequentially include a first conduit 1, a second conduit 4, and a third conduit 5 in the direction of the copper rod inlet. A flaw detector 3 is provided between the first conduit 1 and the second conduit 4;

[0043] An output end of the first conduit 1 is installed with a transition conduit 2. An output end of the transition conduit 2 is close to an inlet of the flaw detector 3, and the transition conduit 2 is coaxially arranged with both the output end of the first conduit 1 and the inlet of the flaw detector 3;

[0044] The copper rod enters the transition conduit 2 from the first conduit 1 and is transmitted into the inlet of the flaw detector 3.

[0045] Specifically, this embodiment discloses a flaw detector device provided with a transition conduit. According to the structure of the existing flaw detector device, it is divided into a first conduit 1, a second conduit 4, and a third conduit 5. Among them, a flaw detector 3 is provided between the first conduit 1 and the second conduit 4. It is necessary to ensure that the inlets of the first conduit 1, the second conduit 4, the third conduit 5, and the flaw detector 3 are all coaxially arranged to provide a straight transmission and detection channel for the copper rod. Since the distance between the first conduit 1 and the flaw detector 3 is relatively far, therefore, in this embodiment, a transition conduit 2 is installed on the first conduit 1, and the output end of the transition conduit 2 is close to the inlet of the flaw detector 3. In this way, the transition conduit 2 provides a guiding basis for the movement of the copper rod.

[0046] Preferably, the first conduit 1, the second conduit 4, and the third conduit 5 of this embodiment are all supported on the device integration frame 6 through conduit support frames 601;

[0047] A conduit support frame 601 of the first conduit 1 is connected with an extension frame 602 on the side close to the second conduit 4, and the end of the extension frame 602 is integrated with a flaw detector 3.

[0048] Preferably, one end of the transition conduit 2 of this embodiment is assembled and fixed with the output end of the first conduit 1, and the distance between the other end of the transition conduit 2 and the inlet of the flaw detector 3 is not greater than 30 mm.

[0049] Making the output end of the transition conduit 2 close enough to the inlet of the flaw detector 3 can avoid the copper rod from shifting during transmission due to too large a distance.

[0050] Preferably, the transition conduit 2 of this embodiment is configured with a structure in which the inner diameter of the end cooperating with the first conduit 1 is larger than the inner diameter of the end cooperating with the inlet of the flaw detector 3.

[0051] Specifically, the transition conduit 2 of this embodiment includes:

[0052] An assembly section 201 assembled and fixed with one end of the first conduit 1;

[0053] A horizontal section 202 close to the inlet of the flaw detector 3; and

[0054] A conical barrel section 203 formed between the assembly section 201 and the horizontal section 202;

[0055] The lengths of both the assembly section 201 and the horizontal section 202 are 30 mm, and the inner diameter of the horizontal section 202 is consistent with the aperture of the entrance of the flaw detector 3.

[0056] In order to achieve the assembly and fixation of the assembly section 201 and the first conduit 1, the inner diameter of the assembly section 201 in this embodiment is larger than the outer diameter of the first conduit 1, and the assembly section 201 is sleeved outside the first conduit 1;

[0057] The assembly section 201 is provided with mounting holes 204 along its radial direction, and the assembly section 201 is assembled and fixed to the first conduit 1 through bolts in the mounting holes 204.

[0058] All parts inside the transition conduit 2 in this embodiment need to have a smooth transition. Therefore, the transition positions between the conical barrel section 203 and the horizontal section 202 and the assembly section 201 in this embodiment are all transitioned by arcs.

[0059] In the above technical solution, an eddy current flaw detector device with a transition conduit provided by the present utility model has the following beneficial effects:

[0060] The flaw detector device of the present utility model is provided with a transition conduit 2 between the first conduit 1 and the flaw detector 3. The transition conduit 2 guides the copper rod in a way that the inner diameter gradually decreases for transition, corrects the path of the copper rod transportation, and ensures that the copper rod can smoothly enter the flaw detector with a passing rate of 100%.

[0061] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
