[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Using the solution proposed in this application, the pilot controls the drone body equipped with the measuring unit to approach the conductor under test from below. The conductor enters through the upper openings of the two funnel-shaped guide plates in the front and rear guide plate groups. As the drone body continues to rise, the conductor under test gradually moves downward to the upper end of the sampling pin. At this point, the sampling pin, which is at the corresponding position of the conductor under test, is pressed down under the action of external force. It continues to move downward until it reaches the upper end of the square frame. At this point, the width of the pressed sampling pin is the outer diameter of the conductor under test.

[0033] Example 1

[0034] This embodiment provides a wire diameter measuring device based on a drone, including a drone body 12 and a measuring unit installed on the upper part of the drone body 12;

[0035] The measurement unit includes a square frame 5 connected to the upper end of the UAV body 12. The square frame 5 is a box-shaped structure with an open top, including four side walls and a bottom wall. The front and rear sides of the upper end of the square frame 5 are respectively provided with a front guide plate group and a rear guide plate group for guiding the test wire, which are in the same position and have the same structure.

[0036] Both the front guide plate group and the rear guide plate group include two guide plates 8 that are symmetrically arranged and funnel-shaped.

[0037] The upper end of the square frame 5 is provided with a horizontally arranged mold-taking needle fixing block 13. The mold-taking needle fixing block 13 is provided with a plurality of mold-taking needles 1 arranged side by side in a longitudinal direction for measuring the diameter of the wire to be measured. The longitudinal position of the mold-taking needles 1 is adjustable.

[0038] The side end face of the mold-taking pin fixing block 13 is provided with a scale line 14 that is used in conjunction with the mold-taking pin 1.

[0039] During use, the pilot controls the drone, which carries the measuring unit, to approach the conductor under test from below. The conductor enters through the openings at the top of the two funnel-shaped guide plates in the front and rear guide plate groups. As the drone continues to rise, the conductor gradually moves downward to the top of the sampling pin. At this point, the sampling pin, corresponding to the guide plate, is pressed down by external force. The conductor continues to move downward until it reaches the top of the square frame. The width of the pressed sampling pin is the outer diameter of the conductor under test. The outer diameter value can be read through the scale, which is convenient, fast, and highly safe.

[0040] It should be noted that the drone body 12 was purchased externally and uses existing technology.

[0041] Example 2

[0042] Based on the above embodiments, this embodiment provides multiple air holes 6 on each of the four sides of the square frame 5 to allow air to pass through, thereby reducing the impact of wind.

[0043] Example 3

[0044] This embodiment provides a specific implementation structure for the front guide plate group and the rear guide plate group.

[0045] The front guide plate group and the rear guide plate group are each connected to a limiting plate mechanism. The limiting plate mechanism includes a limiting plate 7 and a limiting block 2. The upper end of the limiting plate 7 is hinged to the guide plate at the corresponding position. The limiting block 2 is installed on the outside of the square frame 5 and is provided with an upward-opening limiting groove 9. The lower end of the limiting plate 7 is inserted into the limiting groove 9. The side wall of the limiting groove 9 is connected to one end of a spring 10, and the other end of the spring 10 abuts against the limiting plate 7.

[0046] The limiting plate mechanism is set up so that when the wire to be tested enters the two funnel-shaped guide plates, it will not sway left and right and affect the mold taking.
