[0026] Please see Figure 1 This application provides a remote monitoring device for a wind turbine main gearbox, including a monitoring component 1 and a connecting component. The connecting component includes a connecting line 2, a fixing ring 3, a first circular plate 4, a side plate 5, a first external threaded rod 7, a first nut 8, a clamp 9, and a clamping ring 10. The lower surface of the monitoring component 1 is sequentially connected to the first circular plate 4 and the side plate 5. The two sides of the side plate 5 are provided with sliding grooves 6. The first external threaded rod 7 is engaged with the sliding groove 6 and moves in the sliding groove 6. The first nut 8 is sleeved on the outer wall of the first external threaded rod. The two ends of the clamp 9 are respectively connected to the first external threaded rod 7 and the clamping ring 10. The connecting line 2 is respectively connected to the clamping ring 10 and the monitoring component 1. The fixing ring 3 is sleeved on the outer wall of the connecting line 2.

[0027] In the technical solution provided in this application embodiment, a first circular plate 4 and a side plate 5 are sequentially connected to the lower surface of the monitoring component 1. Slide grooves 6 are provided on both sides of the side plate 5, and the slide grooves 6 on both sides are symmetrically arranged. Each slide groove 6 has a first externally threaded rod 7 that engages with the slide groove 6 and moves within it. A first nut 8 is fitted onto the outer wall of the first externally threaded rod 7 to fix the first externally threaded rod 7 and the clamp 9. The first externally threaded rods 7 on both sides are fixed to the clamp 9. This constitutes the first connection structure between the monitoring component 1 and the connecting component.

In the technical solution provided by the embodiments of this application, the monitoring component 1 is fixedly connected by a dual connection structure of the monitoring component 1 and the connecting component. Even if one of the connection structures becomes loose, the fixed relationship between the monitoring component 1 and the connecting component can still be ensured. This effectively prevents the monitoring component 1 from being damaged due to the loose connection structure and solves the technical defect of unstable connection structure in the existing wind turbine main gearbox monitoring device.

[0035] To further optimize the technical solution, the monitoring device provided in this application embodiment further includes a counterweight 34, which is snapped into the fixed frame 33. The counterweight 34 can further increase the overall structural stability of the support component when encountering external forces, such as strong winds or external thrust, and prevent damage to the monitoring component 1 caused by the tipping of the monitoring device.

[0036] Further optimize the technical solution to improve the support stability of the support components and prevent the pressure ring 29 from slipping and tipping over. Please refer to the following for further details.

[0038] The fixing block 14 is located on the top of the monitoring component 1. In actual installation, to increase the connection stability between the monitoring component 1 and the fixing block 14, and to facilitate the connection between the monitoring component 1 and the fixing block 14, the fixing block 14 is welded to the top of the monitoring component 1. Further, after the third external threaded rod 15 is fixed to the side of the fixing block 14, the third external threaded rod 15 and the third nut 18 are connected and fixed to the fixing component via the rotating plate 17. When storing the fixing component, the fixing bracket 16 is rotated around the third external threaded rod 15 until the third nut 18 is against the side of the rotating plate 17.

[0039] Please refer to this section for further information.
