Description

Technical Field

[0001] This utility model relates to the field of large machinery maintenance technology, specifically a tool for preventing foreign objects from entering the stator bore of a generator. Background Technology

[0002] During the maintenance of large machinery, the generator end cover needs to be removed for maintenance. After the generator end cover is removed, the two sides of the stator cavity become open holes. In order to prevent foreign objects from entering, the two sides of the stator cavity need to be sealed. However, the existing methods are to either not seal or to use other plates for sealing. The method of not sealing will only increase the entry of foreign objects into the stator cavity. The method of using plates for sealing requires fixing the plates, but the plates are not easy to fix to the generator, the operation is cumbersome and complicated, wastes a lot of time, and the effect is relatively poor, which increases the sealing cost. Therefore, a tool for preventing foreign objects from entering the generator stator cavity is provided. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a tool for preventing foreign objects from entering the stator bore of a generator, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foreign object protection tool for a generator stator bore, comprising a first polyester fabric, a second polyester fabric, a third polyester fabric, and a fourth polyester fabric. The first, second, third, and fourth polyester fabrics are all fan-shaped. They are spliced ​​together to form a circular foreign object protection tool, with a hole at the center. Velcro is sewn onto the outside of the hole. Velcro and Velcro fasteners are sewn onto the two right-angled edges of the first, second, third, and fourth polyester fabrics. Magnetic strips are sewn onto the arc edges of the first, second, third, and fourth polyester fabrics. Doorways are opened on the first and second polyester fabrics, with Velcro sewn onto the outside of the doorways.

[0005] As a preferred embodiment of this utility model, the doorway is connected to an access door via Velcro; the opening is connected to a curtain via Velcro.

[0006] As a preferred embodiment of this utility model, the first polyester fabric is connected to the second and third polyester fabrics by Velcro and Velcro, and the fourth polyester fabric is connected to the second and third polyester fabrics by Velcro and Velcro.

[0007] As a preferred embodiment of this utility model, several hanging holes are provided on the edges of both the first polyester fabric and the second polyester fabric.

[0008] As a preferred embodiment of this invention, magnetic strips are sewn onto the edges of the holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the tool is designed as a splicable anti-foreign object tool according to the size of the generator stator cavity. The tool is flexible, which not only makes it easy to assemble and splice, but also makes it very simple and convenient to install. Four pieces of polyester cloth are fixed to the generator stator cavity in sequence by magnets, thereby splicing them into an anti-foreign object tool to seal the generator stator cavity. Moreover, the four pieces of polyester cloth are connected to each other by Velcro and nylon fasteners, which not only makes assembly convenient, but also makes it easier to disassemble and reuse later. The tool provides a fully enclosed seal for the generator stator cavity, providing good protection.

[0010] The tool can also be assembled before installation. It uses magnets to magnetically attract the generator stator cavity, thus fixing the tool in place and preventing it from falling off. It also uses curtains and access doors to seal some holes, ensuring that foreign objects cannot enter. Attached Figure Description
