In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0026] Please refer to Figures 1 to 6 , the present utility model provides a technical solution:

[0027] Embodiment 1, an alarm for a main drive chain fault warning system of a wind turbine. The alarm for the main drive chain fault warning system of a wind turbine includes: a mounting base 1 and a housing main body 2.

[0028] Specifically, one end of the mounting base 1 is plugged and fixed with the housing main body 2. A baffle 5 for blocking dust is fixedly connected to the outside of the housing main body 2. The upper end of the baffle 5 is set as an inclined arc surface. The baffle 5 can block the falling dust outside the gap between the housing main body 2 and the mounting base 1, preventing dust from accumulating at the gap. Moreover, the inclined arc surface at the upper end of the baffle 5 itself can also make the dust slide out of the baffle 5 better, avoiding too much dust accumulation on the baffle 5. A mounting block 3 is slidably connected to the side of the mounting base 1. A plurality of springs 6 distributed in a circumferential array are fixedly connected between the mounting block 3 and the mounting base 1. A sealing gasket 4 is fixedly connected to the inner side of the mounting block 3. After the mounting block 3 and the sealing gasket 4 slide, they contact the baffle 5 and correspond to the position of the gap between the housing main body 2 and the mounting base 1. After the housing main body 2 is plugged and fixed, the spring 6 will push the mounting block 3 and the sealing gasket 4 to contact the baffle 5, and then the sealing gasket 4 will block the gap at the connection between the housing main body 2 and the mounting base 1, effectively preventing dust from entering the inner cavity of the housing main body 2.

[0029] To facilitate the plugging and fixing of the housing main body 2, two symmetrically arranged iron blocks 7 are fixedly connected to one end of the baffle 5 of the present application. Both iron blocks 7 are slidably inserted into the mounting block 3. Two magnets 8 corresponding to the positions of the iron blocks 7 are slidably connected to the side of the mounting block 3. After the magnets 8 slide, they are inserted into the iron blocks 7. When installing the housing main body 2, first slide the magnets 8 away from the mounting base 1, and then slide the iron blocks 7 into the mounting block 3. After the iron blocks 7 are inserted in place, the magnets 8 will slide into the iron blocks 7 under the attraction force, thus fixing the housing main body 2 on the mounting base 1 very conveniently. This also facilitates the subsequent inspection and maintenance of the alarm.

[0030] To facilitate the sliding installation of the magnets 8, two convex plates 9 are fixedly connected to the side of the mounting block 3 of the present application. A slider 81 set in a "T" shape is fixedly connected to one side of the magnet 8. The slider 81 can prevent the magnet 8 from falling off the convex plate 9. A sliding groove 91 for the sliding installation of the slider 81 is opened on one side of the convex plate 9. Through the sliding connection between the slider 81 and the sliding groove 91, the magnet 8 can be stably slidably installed on the mounting block 3.

[0031] To more accurately position the iron block 7, a positioning hole 33 for the iron block 7 to slide and insert is formed through one end of the mounting block 3 of the present application. The positioning hole 33 can make the position of the iron block 7 more accurate when inserted. A slot 71 for the magnet 8 to slide and insert is formed on one side of the iron block 7. The slot 71 can enable the magnet 8 to be better inserted into the iron block 7, thereby better restricting the sliding of the iron block 7 and further ensuring the stable installation of the housing main body 2.

[0032] To facilitate the sliding installation of the mounting block 3, a plurality of guide rods 31 distributed in a circumferential array are fixedly connected to one end of the mounting block 3 of the present application. A support plate 11 is fixedly connected to the side surface of the mounting base 1. The plurality of guide rods 31 are all slidably inserted into the support plate 11, and the spring 6 is located between the mounting block 3 and the support plate 11. In this way, the mounting block 3 can be stably slidably installed on the mounting base 1, and at the same time, the spring 6 can better exert its elastic effect.

[0033] For the stable installation of the mounting block 3, a jack 12 for the guide rod 31 to slide and insert is formed through one end of the support plate 11 of the present application. The jack 12 can facilitate the sliding insertion of the guide rod 31. A limit block 32 is fixedly connected to one end of the guide rod 31. The limit block 32 can prevent the guide rod 31 from sliding out of the support plate 11.

[0034] During actual implementation, first, the two magnets 8 are slid away from the mounting base 1. Then, the iron block 7 is inserted into the positioning hole 33. Finally, the housing main body 2 will contact the mounting base 1. After the iron block 7 is inserted in place, the magnet 8 will also slide and insert into the slot 71 under the action of the attraction force, thereby restricting the sliding of the iron block 7, and then fixing the housing main body 2 on the mounting base 1. In this way, the installation of the housing main body 2 becomes very convenient. The baffle 5 on the housing main body 2 can block the dust floating from above outside the gap between the housing main body 2 and the mounting base 1, avoiding the accumulation of dust on the mounting block 3 and the sealing gasket 4. The mounting block 3 and the sealing gasket 4 will also be pressed against the baffle 5 under the action of the spring 6, and the sealing gasket 4 seals the gap between the housing main body 2 and the mounting base 1 to ensure that no dust enters the inner cavity of the housing main body 2.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
