Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning brushes, and specifically relates to a rotor magnetic pole cleaning fixture. Background Technology

[0002] As core equipment in power generation, the stable operation of large generator sets is crucial. The rotor poles are key components of the generator set. During long-term operation, a large amount of impurities, including dust, oil, and metal debris, accumulate on the surface of the poles. These impurities affect the heat dissipation performance of the poles, causing their temperature to rise during operation, thereby reducing the efficiency and stability of the generator set. Furthermore, impurities may alter the electromagnetic properties of the poles, resulting in uneven magnetic field distribution, severely affecting power generation quality, and even causing malfunctions that threaten the safe supply of the power system. Therefore, regularly cleaning the rotor poles is a necessary measure to ensure the reliable operation of the generator set.

[0003] Traditional methods often involve manual cleaning using ordinary brushes or wire brushes. However, manual cleaning is inefficient. Large generator sets have a large number of magnetic poles, and the surface of the magnetic poles is curved or irregularly shaped, making cleaning work a labor-intensive and time-consuming task. In addition, it is difficult to guarantee the cleaning quality. The force and cleaning range of manual operation are difficult to be uniform, which can easily lead to incomplete cleaning. Some corners and complex structural parts of the magnetic poles are difficult to clean thoroughly. Utility Model Content

[0004] This invention provides a rotor magnetic pole cleaning fixture to solve the problem of low cleaning efficiency of magnetic pole surfaces.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A rotor magnetic pole cleaning fixture includes a hexahedral base, the base including adjacent first sidewalls and second sidewalls, the first sidewalls having a plurality of first mounting holes facing inward, and the second sidewalls having a plurality of second mounting holes facing inward.

[0007] Each of the first mounting holes is equipped with a flexible cleaning brush, and each of the second mounting holes is equipped with a flexible scraper.

[0008] Furthermore, the elastic cleaning brush includes a cleaning tube and a first elastic pusher, the first elastic pusher giving the cleaning tube a thrust in a direction away from the base;

[0009] The elastic scraper includes brush teeth and a second elastic pusher, the second elastic pusher giving the brush teeth a thrust in a direction away from the base.

[0010] Furthermore, the brush teeth include a mounting base and a plurality of bristles, the bristles being fixed to the mounting base, and the second elastic pusher abutting against the side of the mounting base away from the bristles.

[0011] Furthermore, the cross-section of the bristles is flat or is that of a wire brush.

[0012] Furthermore, the cleaning tube includes an infusion rod, a flow restrictor, and a reservoir arranged in sequence. The flow restrictor is located at the open end of the reservoir, and an outlet is provided on the flow restrictor.

[0013] The infusion rod has an infusion channel inside, and the infusion channel is connected to the outlet.

[0014] Furthermore, a sponge brush can be detachably installed at the end of the infusion rod away from the reservoir.

[0015] Furthermore, the inner walls of the ends of both the first and second mounting holes are threaded with limit rings, which are used to prevent the elastic cleaning brush from disengaging from the first mounting hole and the elastic scraper from disengaging from the second mounting hole.

[0016] Furthermore, the sidewalls of the first and second mounting holes are provided with guide ridges along their depth direction, and the cleaning tube and the mounting base are slidably engaged with the guide ridges.

[0017] Furthermore, a first handle is provided on the side wall opposite to the first side wall, and a second handle is provided on the side wall opposite to the second side wall.

[0018] The present invention can achieve the following beneficial effects:

[0019] 1. This application provides an elastic cleaning brush on the first side wall of the base and an elastic scraper on the second side wall. When cleaning curved workpieces, the elastic cleaning brush can be used to apply cleaning fluid to the surface of the workpiece first, and then the base can be rotated to scrape off the dirt using the elastic scraper. The elastic cleaning brush and the elastic scraper can be matched to the curvature of the curved workpiece surface, thereby improving the convenience of cleaning curved workpieces.

[0020] 2. The first elastic pusher and the second elastic pusher continuously provide thrust to the cleaning tube and brush teeth, so that the cleaning tube and brush teeth can match the surface of the curved workpiece for cleaning, resulting in high cleaning efficiency; the first handle and the second handle are provided to facilitate the staff to hold and use the tooling of this application for cleaning.

[0021] 3. An outlet is opened on the flow restrictor, so that the cleaning fluid in the reservoir can seep out evenly and slowly through the outlet and the delivery channel to the sponge brush, and then be evenly coated onto the surface of the curved workpiece through the sponge brush, so that the cleaning fluid can be coated more evenly.

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] like Figures 1 to 4As shown, a rotor magnetic pole cleaning fixture includes a base 1, which is hexahedral in shape. The base 1 includes adjacent first sidewalls 11 and second sidewalls 12. The first sidewall 11 has several first mounting holes 111 facing inwards, each containing an elastic cleaning brush 2. The second sidewall 12 has several second mounting holes 121 facing inwards, each containing an elastic scraper 3. Firstly, the elastic cleaning brushes 2 apply cleaning fluid to the workpiece surface, and then the elastic scrapers 3 remove dirt from the workpiece surface. A first handle 4 is provided on the sidewall opposite the first sidewall 11, and a second handle 5 is provided on the sidewall opposite the second sidewall 12, allowing the operator to move and operate the cleaning fixture by holding either the first handle 4 or the second handle 5.

[0031] Specifically, the elastic scraper 3 includes brush teeth 31 and a second elastic pusher 32. The second elastic pusher 32 can be a spring, and in its natural state, the brush teeth 31 extend out of the surface of the base 1. When the elastic scraper 3 is pressed against the surface of the workpiece to be cleaned, the brush teeth 31 can compress the second elastic pusher 32, thereby realizing the function of adapting several brush teeth 31 to the surface of the curved workpiece, thus making the cleaning of the surface of the curved workpiece more convenient and faster.

[0032] The brush teeth 31 include a mounting base 311 and a plurality of bristles 312. The bristles 312 are fixed on the mounting base 311. The second elastic pusher 32 abuts against the side of the mounting base 311 away from the bristles 312. The bristles 312 can be steel wire bristles 312 or bristles 312 made of other hard materials. In another preferred embodiment, the cross-section of the bristles 312 is flat, which can increase the contact area between the bristles 312 and the curved workpiece surface, thereby better scraping off the dirt on the workpiece surface.

[0033] The elastic cleaning brush 2 includes a cleaning tube 21 and a first elastic pusher 22. The first elastic pusher 22 and the second elastic pusher 32 are designed on the same principle. When the elastic cleaning brush 2 is used to apply cleaning fluid, the first elastic pusher 22 also applies a pushing force to the cleaning tube 21 in the direction away from the base 1, thereby making the surface of the cleaning tube 21 fit the curved workpiece more closely.

[0034] The cleaning tube 21 includes an infusion rod 211, a flow restrictor 212, and a reservoir 213 arranged sequentially. The flow restrictor 212 is located at the open end of the reservoir 213 and has an outlet 2121. The infusion rod 211 has an infusion channel 2111 connected to the outlet 2121. In one embodiment, the reservoir 213 has an injection port on its side wall. When the cleaning fluid in the reservoir 213 is depleted, it can be injected into the reservoir 213 under high pressure through the injection port to replenish the cleaning fluid. In another embodiment, the reservoir 213 and the flow restrictor 212 are integrally formed, and the flow restrictor 212 and the end face of the infusion rod 211 are detachably connected. Therefore, when the cleaning fluid in the reservoir 213 is depleted, a new reservoir 213 can be directly replaced to replenish the cleaning fluid.

[0035] A sponge brush 214 is detachably installed at the end of the infusion rod 211 away from the reservoir 213. When the elastic cleaning brush 2 comes into contact with the surface of the curved workpiece, the second elastic pusher 32 provides elastic thrust to the reservoir 213, causing the reservoir 213 to fold and contract. This squeezes the cleaning fluid inside along the outlet 2121 and the infusion channel 2111 to the sponge brush 214 for absorption, and then evenly coats the workpiece surface through the sponge brush 214. By setting the outlet 2121, the outflow rate of the cleaning fluid can be limited, so that the cleaning fluid can evenly and slowly seep into the sponge brush 214.

[0036] Furthermore, the inner walls of the first mounting hole 111 and the second mounting hole 121 are both threaded with limiting rings 13. The limiting rings 13 are used to prevent the elastic cleaning brush 2 from disengaging from the first mounting hole 111 and the elastic scraper 3 from disengaging from the second mounting hole 121. When replacing the elastic cleaning brush 2 or the elastic scraper 3, the limiting rings 13 can be removed for replacement. The side walls of the first mounting hole 111 and the second mounting hole 121 are provided with guide ribs 14 along their depth direction. The cleaning tube 21 and the mounting base 311 are both slidably engaged with the guide ribs 14, thereby guiding the movement of the cleaning tube 21 and the mounting base 311 through the guide ribs 14, making the movement of the elastic cleaning brush 2 and the elastic scraper 3 more stable. It should be noted that the areas where each part of the cleaning tube 21 interferes with the guide ribs 14 are recessed inward to form relief grooves.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
