[0022] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0023] See Figures 1 to 4 This utility model provides a cable ranging reel, including a reel 1 rotatably mounted on a base 2. A pressure roller 3 is provided on one side of the reel 1, rotatably mounted on the base 2 and tangentially positioned to the reel 1, so that the cable passes between the pressure roller 3 and the reel 1, causing both the pressure roller 3 and the reel 1 to rotate. The cable ranging reel also includes a measuring mechanism that measures the length of the cable passing between the pressure roller 3 and the reel 1. This technical solution can conveniently and accurately measure the length of cables and wind turbine blade test signal lines, and is characterized by ease of use and calibration. The pressure roller 3 can fix the cable, such as the test signal line, in a certain position, preventing the cable from shaking during the laying process and affecting measurement accuracy. The pressure roller 3 can be made of an elastic material to accommodate cables of different diameters.

[0024] In some embodiments, the measuring mechanism includes a plurality of gears, each gear having a graduation engraved on it. The graduated gears rotate with the spool 1. The gears accurately reflect the rotation angle and number of rotations of the spool. The mechanical rotation distance of the spool can be converted into a digital value, and the reading can be obtained by observing the graduations.

[0025] Specifically, the plurality of gears includes a units counting gear 4 and a tens counting gear 5, which mesh with each other and are rotatably mounted on the base 2. The units counting gear 4 is driven by the coil 1.

[0026] The center axis of the wire coil 1 is fixedly connected with a main shaft 6, the main shaft 6 is rotatably installed on the base 2, and the main shaft 6 is coaxially fixedly connected with a unit counting gear 4. The unit counting gear 4 is driven by the wire coil 1 through synchronous rotation of the main shaft 6 and the unit counting gear 4.

[0027] One side of the unit counting gear 4 is fixedly connected with a pinion 41, the pinion 41 is coaxially arranged with the unit counting gear 4, and the unit counting gear 4 is meshed with a ten-counting gear 5 through the pinion 41. The gear ratio of the pinion 41 on the unit counting gear 4 and the ten-counting gear 5 is 1:10. When the cable passes between the wire pressing roller 3 and the wire coil 1, the unit counting gear 4 drives the ten-counting gear 5 to rotate.

[0028] The measuring mechanism further comprises a shell 7, the shell 7 is detachably installed on the base 2, the shell 7 covers all gears, and a reading window 71 is formed in the shell 7.

[0029] The wire pressing roller 3 and the wire coil 1 are circumferentially provided with grooves 8 on the side walls, and the grooves 8 on the wire pressing roller 3 and the wire coil 1 are opposite to each other to clamp the cable. The grooves 8 on the wire pressing roller 3 and the wire coil 1 are used to limit the displacement of the cable, which helps to improve the accuracy of measurement.

[0030] In use, the cable passes between the wire pressing roller 3 and the wire coil 1, and the grooves 8 limit the displacement of the cable. Pulling the cable, the wire coil 1 rotates synchronously with the cable, driving the unit counting gear 4 to rotate, and the scale digital information on the unit counting gear 4 and the ten-counting gear 5 is obtained through the reading window 71.

[0031] After the measurement is completed, the cable is taken out, the shell 7 is removed, the unit counting gear 4 and the ten-counting gear 5 are taken out, the positions of the unit counting gear 4 and the ten-counting gear 5 are adjusted according to the scale marks, and the zero reset can be completed by reinstallation.

[0032] The technical scheme has the characteristics of convenient measurement and easy calibration. Through the cooperation of the gears, the length of the cable can be quickly measured, and the time of manual measurement is effectively reduced. The wire pressing roller 3 ensures the stable unwinding of the cable, the reading window 71 displays the length scale information in real time, the operator can conveniently obtain the cable length information, and the working efficiency is improved. At the same time, the shell 7 can be quickly and accurately calibrated, the unit counting gear 4 and the ten-counting gear 5 are reset to zero, which helps to ensure the reliability of the measurement result.
