In order to measure transposed conductors of different sizes, the detection device in prior art usually uses single-side movable compression structure to cooperate with detection structure to detect the position of jump wire. However, the above-mentioned method also has the following shortcomings: since the position of jump wire is uncertain, when transposed conductor enters, it may be slightly bent due to the action of compression structure, thereby affecting the detection accuracy of detection mechanism.

[0016] The utility model will be explained in further detail below. Figures 1-3 The utility model will be explained in further detail below. EMBODIMENT

[0017] The embodiment provides a transposed conductor online detection device, which comprises a detection box body 1, detection ports 11 for extending in transposed conductors are arranged at two ends of the detection box body 1, an upper detection frame 2 and a lower detection frame 3 are arranged in the detection box body 1, the upper detection frame 2 and the lower detection frame 3 are elastically arranged in the box body 1 to avoid that the uneven surface of the transposed conductor is pressed and slightly bent during detection. Figure 1As shown, the lower detection frame 3 is connected with the bottom wall of the detection box 1 through a plurality of elastic telescopic columns 8; the upper detection frame 2 is provided with a plurality of control rods 21 at the top, the control rods 21 extend out of the upper shell of the detection box 1 and are matched with the screwed nuts 12 arranged outside the detection box 1, which are used for fixing the control rods 21. The outer side of the part of the control rods 21 in the detection box 1 is further wound with a reset spring 22, so that the upper detection frame 2 can be reset upward after the screwed nuts 12 are loosened. Meanwhile, the end of the control rods 21 connected with the upper detection frame 2 is also a telescopic rod, so that the upper detection frame 2 can realize a certain degree of elastic displacement through the reset spring 22 and the telescopic rod part of the control rods 21 after the screwed nuts 12 fix the control rods 21.

[0018] In order to clamp the transposed conductor, the upper detection frame 2 and the lower detection frame 3 are both provided with the guide wheels 4 which are opposite to each other, Figure 1 In the middle, a group of guide wheels 4 are arranged near the two detection ports 11, and more guide wheels 4 can also be arranged between the detection wheels 5 and the detection ports 11 in practice, which are used for stabilizing the transposed conductor.

[0019] The detection module for detecting the jumper is arranged at the center of the detection frame, and the upper and lower detection frames are both provided with the detection module, such as Figure 2 As shown, the detection module includes the detection wheel 5 for detecting the width change of the jumper of the transposed conductor, the connecting rod 52 for elastically connecting the detection wheel 5 with the detection frame, the L-shaped rods 51 on both sides of the connecting rod 52, the detection spring 62 connecting the two L-shaped rods 51, the pressure sensor 61 for detecting the elastic force of the detection spring 62, and the controller 63 for receiving the data of the pressure sensor 61 and issuing an alarm according to the data. The difference from the prior art is that the detection mode of the detection module in the embodiment converts the traditional one-way deformation variable detection into bidirectional detection, the width change of the jumper of the transposed conductor is converted into the length change of the detection spring 62 through the elastically arranged detection wheel 5, and the upper and lower detection wheels 5 are both elastically clamped, so that the transposed conductor is not easy to be bent, and the precision loss caused by the deformation of the transposed conductor is reduced.

[0020] The structure of the elastically arranged detection wheel 5 in the detection frame is as shown in Figure 3 As shown, the detection frame is provided with the connecting column 7 with an inner cavity on one side, the end of the detection wheel 5 is connected with the connecting rod 52, the connecting rod 52 passes through the inner cavity of the connecting column 7 and the detection frame and is connected with the L-shaped rod 51; the part of the connecting rod 52 in the inner cavity of the connecting column 7 is provided with a limiting ring 53, and a spring is arranged between the limiting ring 53 and the detection frame. The K value of the spring should be as small as possible while meeting the elastic force of the detection wheel 5, so as to avoid the situation that the spring pushes open the detection frame.

[0021] In use, the transposed conductor is inserted into the detection box 1, and the upper detection frame 2 is pressed, the controller 63 changes the width of the jumper according to the size of the transposed conductor, adopts a suitable detection spring, and sets a corresponding alarm threshold through the controller. The alarm threshold only needs to meet the requirement of obtaining the width change of the jumper position of the transposed conductor, so it is not necessary to pay attention to the mutual influence among the multiple springs in the embodiment, and the threshold setting can be obtained in a way of detecting first and setting later if necessary. When the transposed conductor continuously enters, the surface unevenness is offset by the elastic connection between the upper and lower detection frames and the inner wall of the box, and the detection wheels always maintain the tight pressing state of the transposed conductor under the action of the connecting rod and the connecting column. When the jumper part enters the detection wheel position, the two detection wheels are pushed open, pull the detection spring 62 under the action of the L-shaped rod, and the pressure sensor measures the elastic force of the detection spring 62. When the elastic force changes beyond the threshold, the controller sends a prompt.

[0022] The above are preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
