[0001] The utility model relates to the technical field of wind power generators, in particular to a protective cover for a brake coupling of a high-speed shaft of a generator. Background Art

[0002] In the brake mechanism of a small wind turbine generator set, most of the generator high-speed shaft brake couplings are exposed to the outside, which is prone to safety hazards. However, according to national regulations, various rotating parts of mechanical equipment (such as conveyor belts, gear machines, couplings, flywheels, etc.) must be equipped with protective devices, so it is necessary to cover and protect the existing generator high-speed shaft brake coupling. To this end, it is necessary to use a generator high-speed shaft brake coupling protective cover to meet its needs, but the existing protective cover, such as the wind turbine brake device protective cover with publication number: CN215596251U, includes a first brake pad, a gear box, a first connecting member, a second connecting member, a brake disc, a first protective cover, a second brake pad, a third connecting member, a second protective cover, a coupling, a fourth connecting member, a generator, a first connecting device and a second connecting device.

[0003] In the above scheme, the entire protective cover is inconvenient to install and cannot be added. At the same time, the oil dripping when the drive shaft is working is easy to accumulate, causing safety hazards. Therefore, this application provides a generator high-speed shaft brake coupling protective cover to meet the needs. Utility Model Content

[0010] Optionally, the support mechanism includes a support frame fixedly connected to the bottom end of the lower clamping ring, and the bottom end of the support frame is fixedly connected to a mounting seat.

[0011] Optionally, the inner wall surfaces of the upper shell cover and the lower shell cover are both provided with sound-absorbing holes, and the upper shell cover and the lower shell cover are both provided with sound-insulating pads inside.

The connecting ring sleeve 2 is fixedly connected to one end of the brake disc cover 1, and the shaft cover 3 is rotatably installed inside the connecting ring sleeve 2. The supporting mechanism 4 is fixedly connected to the bottom end surface of the connecting ring sleeve 2. The brake disc cover 1 is used to protect the shaft brake disc, and the shaft cover 3 is used to protect the transmission shaft. The set brake disc cover 1 and the shaft cover 3 facilitate the cover buckle protection of the brake disc and the connecting shaft. At the same time, the setting of the connecting ring sleeve 2 facilitates the rotation and adjustment of the position of the shaft cover 3, so that the entire device can fully meet the required length of the protective mechanism, thereby shielding it to meet the protection requirements.

[0033] like Figures 1 to 3 As shown, the brake disc cover 1 includes an upper shell cover 5 and a lower shell cover 6 connected by a connecting buckle, and the connecting ring sleeve 2 includes an upper snap ring 7 and a lower snap ring 8 connected by a connecting buckle, the upper snap ring 7 is fixedly connected to the upper shell cover 5, and the lower snap ring 8 is fixedly connected to the lower shell cover 6.

[0035] like Figure 3 and Figure 4 As shown, a liquid storage box 13 is fixedly connected to one end of the lower shaft housing 10, and a liquid guide groove 14 is provided on the inner wall of the lower shaft housing 10. The liquid guide groove 14 is interconnected with the inside of the liquid storage box 13.
