The device for monitoring the main shaft bearing of a wind turbine generator set includes: a bearing monitoring box 1, a plurality of connecting lines 2 installed on the side wall of the bearing monitoring box 1, and a detection probe 3 installed on the outer end of the connecting lines 2.

[0024] The side wall of the bearing monitoring box 1 is provided with a movable groove 4. A rotating rod 5 is installed inside the movable groove 4. The rotating rod 5 passes through the side wall of the bearing monitoring box 1. A set of symmetrically placed cable management components 6 are installed on the outer surface of the rotating rod 5. A left threaded groove 17 is provided on the outer surface of one end of the rotating rod 5, and a right threaded groove 18 is provided on the outer surface of the other end of the rotating rod 5.

[0025] In use, the detection probe 3 is placed inside the spindle, and the spindle is monitored through the connecting wire 2 and the bearing monitoring box 1. The cable management assembly 6 moves on the outer surface of the rotating rod 5 through the movable block 7. Through the action of the left thread groove 17 and the right thread groove 18, the cable management assemblies 6 on both sides move inward synchronously, so that the connecting wire 2 can be easily stored inside the cable management assembly 6.

[0026] Example 2

[0027] Based on Embodiment 1, a separation and retraction mechanism is provided for each connection. The cable management assembly 6 includes a movable block 7, which is located at both ends of the outer surface of the rotating rod 5. A set of symmetrically placed ring plates 8 are installed on the side wall of the movable block 7. A partition plate 9 is installed on the side wall of the ring plate 8. A groove 10 is opened at the bottom of the partition plate 9. Several movable partition plates 11 are installed inside the groove 10. A locking rod 12 is installed through the side wall of the partition plate 9. The locking rod 12 passes through the outer side wall of the movable partition plate 11.

[0028] In use, the cable management assembly 6 ring plate 8 collects the connecting wires 2 together, and the connecting wires 2 on both sides are divided into two even parts by the partition plate 9. The movable partition plate 11 inside the groove 10 separates each connection to prevent the connecting wires 2 from sticking together and causing accidents.

[0029] Example 3

[0030] Based on Embodiment 2, a structure is provided to facilitate the installation and fixation of the connecting line 2 by moving the partition 9. A moving rod 13 is installed through the side wall of the ring plate 8. One end of the moving rod 13 is fixed to the side wall of the partition 9. A slot 14 is provided on the side wall of the partition 9. An insert rod 15 is installed through the inside of the moving rod 13. The inner end of the insert rod 15 moves inside the slot 14.

[0031] In use, the partition 9 can be moved to the outer end of the ring plate 8 via the moving rod 13. The insert rod 15 is inserted into the slot 14 under the inward pulling force provided by the spring 16, which fixes the partition 9 and facilitates the connection and fixation of the two ring plates 8.

[0032] Working principle: In actual use, the detection plate 3 is placed inside the main shaft. The main shaft is monitored through the connecting cable 2 and the bearing monitoring box 1. The cable management assembly 6 moves on the outer surface of the rotating rod 5 through the movable block 7. Through the action of the left threaded groove 17 and the right threaded groove 18, the cable management assemblies 6 on both sides move inward synchronously, which facilitates the storage of the connecting cable 2 inside the cable management assembly 6. The ring plate 8 of the cable management assembly 6 collects the connecting cable 2 together. The partition plate 9 separates the connecting cable 2 on both sides into two equal parts. The movable dividing plate 11 inside the groove 10 separates each connection. The partition plate 9 can move movably to the outer end of the ring plate 8 through the moving rod 13. The insertion rod 15 is inserted into the slot 14 under the inward pulling force provided by the spring 16, which fixes the partition plate 9 and facilitates the connection and fixation of the ring plates 8 on both sides. This avoids the problem of multiple cables getting tangled, which would cause the equipment to burn out and become unusable due to the high temperature.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
