Technical Field

[0001] This utility model relates to the technical field of carbon fiber composite conductor testing equipment, specifically a non-destructive testing device for carbon fiber composite conductors. Background Technology

[0002] Carbon fiber composite conductors are a novel type of energy-saving, capacity-enhancing conductor. Compared to conventional conductors, they offer a range of advantages, including lighter weight, higher tensile strength, better heat resistance, lower coefficient of thermal expansion, less sag at high temperatures, higher conductivity, lower line loss, higher current carrying capacity, better corrosion resistance, and resistance to icing. They comprehensively address various technical bottlenecks in overhead power transmission, representing the future technological trend of overhead conductors. This contributes to the construction of safe, environmentally friendly, efficient, and energy-saving transmission networks. They can be widely used for capacity expansion and renovation of existing lines and substation busbars, as well as for new line construction. They are also suitable for lines in special climatic and geographical conditions such as long spans, large elevation differences, heavy icing areas, and high pollution zones. In newly constructed lines, they can increase the unit transmission capacity, ensure the robustness of the power grid, and offer better long-term economic benefits.

Through this structure, the first and second locking grooves on the first and second locking members are locked together by locking bolts and can move back and forth for adjustment. The X-ray emitter is located on the upper end of the second locking member, and the lead screw structure allows the X-ray emitter to move left and right, enabling it to detect three different positions of the non-destructive testing device for carbon fiber composite wires. A placement seat is provided on the second limiting groove, and the non-destructive testing device for carbon fiber composite wires is locked and fixed by the limiting seat at the lower end of the placement seat, making it easy to fix the non-destructive testing device for carbon fiber composite wires inside the fixed base for convenient testing.

[0004] However, the current non-destructive testing devices for carbon fiber composite conductors have the following problems: Traditional non-destructive testing devices for carbon fiber composite conductors perform non-destructive testing during conductor transmission, and the non-destructive testing uses X-ray technology for detection. However, this method is not convenient for screening at fixed locations, so it needs to be improved. Utility Model Content

[0009] Specifically, the lead screw is connected to the displacement adjustment frame via a limiting thread, and a lifting guide rod is rotatably connected to the side end of the displacement adjustment frame.

[0010] Specifically, the detection unit is mounted on the support limiting plate, and the upper end of the detection unit is shielded by a baffle plate.

[0011] Specifically, the wire is transmitted to the lower end of the baffle plate via the transmission guide wheel, and then connected to the lifting guide rod and the driven adjustment wheel for transmission and discharge to the outside.

[0012] Specifically, the motor rotates, which drives the lead screw to rotate. The lead screw drives the displacement adjustment frame to slide on the track frame, changing the position of the lifting guide rod and limiting the lifting of the wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

After that, the machine is stopped for treatment, which helps to better determine the location of the damage and facilitates the treatment work. Attached Figure Description

[0022] The first detection structure 1 includes a support frame plate 5, a motor 6, a transmission guide wheel 7, a support base frame 8, a driven adjustment wheel 9, a baffle plate 10, a support limiting plate 11, a lifting guide rod 12, a motor 13, a base block 14, a track frame 15, and a displacement adjustment frame 16. The motor 6 is fixedly installed on the support frame plate 5, and the motor 6 drives the transmission guide wheel 7 to rotate and adjust. The lower end of the support frame plate 5 is fixedly connected to the support limiting plate 11, which has a baffle plate 10. The front end of the support limiting plate 11 is fixedly connected to the support base frame 8. The driven adjustment wheel 9 is rotatably connected. The first detection structure 1 and the second detection structure 2 are installed. The first detection structure 1 and the second detection structure 2 have the same structure and can be fixed. The support plate 5 can support the motor 6, and the motor 6 drives the transmission guide wheel 7 to rotate, realizing the transmission of the wire. The wire passes through the shielding plate 10 and the lifting guide rod 12 to reach the driven adjustment wheel 9, and then is guided to the outside. During the transmission of the wire, the detection unit 4 and the X-ray machine 3 perform non-destructive testing of the wire to achieve the purpose of automated testing.

[0023] A base frame block 14 is fixedly connected to the upper center of the support base frame 8. A track frame 15 is fixedly connected to the base frame block 14. A motor 13 is installed on the track frame 15. A lead screw is connected to the motor 13 for driving.

[0024] The lead screw is connected to the displacement adjustment frame 16 by a limiting thread. The side end of the displacement adjustment frame 16 is rotatably connected to a lifting guide rod 12. By installing the lifting guide rod 12, when a problem occurs in one section of the wire, the motor 13 can control the lead screw to rotate. The lead screw drives the displacement adjustment frame 16 to move on the track frame 15, thereby stretching and adjusting the lifting guide rod 12 to stretch the wire. After that, the machine is stopped for processing, so as to better determine the location of the damage and facilitate the processing work.

[0025] The detection unit 4 is mounted on the support limiting plate 11, and the upper end of the detection unit 4 is shielded by the shielding plate 10.

At the gap between the baffle plate 10 and the support limiting plate 11, the X-ray machine 3 and the detection unit 4 operate to detect the wire. The X-ray machine 3 and the detection unit 4 utilize existing... After technical setup, the wire passes through the lifting guide rod 12 to the driven adjustment wheel 9, and is then guided to the outside via the driven adjustment wheel 9 to complete the transmission. Simultaneously, detection is performed. If a problem occurs, the motor 13 activates, driving the lead screw to rotate. The lead screw is threadedly connected to the displacement adjustment frame 16, allowing the displacement adjustment frame 16 to slide and adjust on the track frame 15, changing the position of the lifting guide rod 12. At this time, the lifting guide rod 12 stretches the wire, and the equipment stops transmitting the wire. The user can then pinpoint the damaged area to complete the work.
