Technical Field
[0001] The utility model relates to the technical field of cleaning tools for generator sets, in particular to a dust collection tool for a slip ring chamber of a generator set. Background Art
[0002] In a generator set, the slip ring chamber is one of the key components. It is responsible for transmitting electricity from the stationary part to the rotating part and is commonly found in large generators and motors. Since the contact between the slip ring and the brush will produce carbon dust and particles during high-speed rotation, these residues, if not cleaned in time, will not only affect the efficiency and stability of power transmission, but may also cause wear and tear on the equipment and shorten its service life. Traditional cleaning methods mostly rely on manual cleaning with brushes or compressed air, which is time-consuming and labor-intensive, and it is difficult to achieve a thorough cleaning effect. There are also safety hazards during operation, especially for high-voltage and high-current generator sets.
[0003] In view of the above problems, there are some simple dust suction devices on the market that try to solve the cleaning problem of the slip ring chamber, but they generally have defects such as insufficient suction, difficulty in accurately locating tiny gaps, and inconvenient operation. For example, some designs may only be equipped with basic dust suction structures, lacking effective fit for the complex contours of the slip ring surface, resulting in poor cleaning effects; others may ignore the flexibility and safety of operation in a small space, making maintenance personnel face challenges when performing cleaning tasks.
[0004] Therefore, it is particularly urgent to develop an efficient, safe and easy-to-operate dust suction tool specifically for the slip ring chamber of the generator set. This tool needs to be able to fit the special structure of the slip ring chamber tightly, enhance the dust suction capacity through a reasonable negative pressure system design, and be equipped with a brush plate structure that is easy to adjust and position to ensure comprehensive and in-depth cleaning in a limited space. In addition, in order to adapt to different types of generator sets and improve maintenance efficiency, the tool should also have good versatility and a convenient operation mechanism to reduce downtime and maintenance time and ensure the long-term stable operation of power generation equipment.

The duct tape has a first end and a second end, and the duct tape has a second end. The duct tape has a first end and a second end. The duct tape has a second end. The duct tape has a second end. The duct tape has a second end.
[0007] Furthermore, the elastic member is a plurality of springs, and the springs are fixed between the two brush plates in a compressed state.
[0008] Furthermore, the elastic member is an elastic sleeve, one end of which is fixed to the edge of the brush plate in an enclosing manner, and the other end of which is fixed to the negative pressure pipe and enclosed around the air inlet.

[0011] Furthermore, a transverse plate is fixedly connected to the brush plate, the transverse plate is located in the middle of the connecting hole, and the first bristles are fixed in an H shape on the side edges of the transverse plate and the brush plate.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. Enhanced cleaning efficiency and effect: The combination of the negative pressure fan and the negative pressure pipe can generate strong suction to effectively absorb dust and particles accumulated in the slip ring chamber. The triangular-shaped boss design increases the stability of the negative pressure area, making the dust collection process more efficient.

DETAILED DESCRIPTION
[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] like Figures 1 to 4As shown, the embodiment of the utility model proposes a dust collection tool for the slip ring chamber of a generator set, including a negative pressure fan, a negative pressure pipe 1, a brush plate 2, two connecting frames 3 and a fixing plate 4, wherein the negative pressure fan is connected to the negative pressure pipe 1 through a connecting pipe, and air inlets 5 are symmetrically provided on both sides of the end of the negative pressure pipe 1, and a boss 6 with a triangular cross section is fixedly connected to the inner top of the negative pressure pipe 1, a connecting hole 7 corresponding to the air inlet 5 is provided in the middle of the brush plate 2, and a first brush 8 is fixedly connected around the connecting hole 7, and a brush plate 2 is provided between the brush plates 2 to brush the air inlets 5 when the brush is in the working state. The plate 2 is an elastic member propped open, one end of the two connecting frames 3 is respectively fixed on both sides of the two brush plates 2, the middle part of the connecting frame 3 is hinged on the negative pressure tube 1, the other ends of the connecting frames 3 are converged together, and an arc groove 9 is opened on the adjacent side of the connecting frame 3, the fixed plate 4 is fixed on the negative pressure tube 1 and is located above the connecting frame 3, a slide groove 10 is opened on the fixed plate 4, a push column 11 is slidably connected in the slide groove 10, and the bottom of the push column 11 is located between the slide grooves 10 of the two connecting frames 3, and the push column 11 is slid on the fixed plate 4 so that the connecting frame 3 brings the two brush plates 2 closer to each other.
[0025] The working principle is: Figure 1 As shown, when cleaning, the negative pressure fan is started and the air volume of the negative pressure fan is adjusted. The operator pushes the push column 11 forward on the fixed plate 4, and the push column 11 moves forward to prop open one end of the two connecting frames 3 with the arc groove 9. Through the hinged setting, the other ends of the connecting frames 3 are brought close to each other, so that the two brush plates 2 are close to the side air inlet 5 of the negative pressure pipe 1, reducing the volume of the negative pressure pipe 1, and extending the top of the negative pressure pipe 1 into the narrow part of the slip ring chamber. The push column 11 is released, and the brush plate 2 is pressed against the narrow part of the slip ring under the action of the elastic member. , so that the first bristles 8 on the brush plate 2 are in full contact with the surface of the slip ring, and even complex slip ring contours can be effectively cleaned. Regardless of the specific shape of the slip ring chamber, the elastic member can push the brush plate 2 against the surface of the slip ring to achieve precise positioning and fit, thereby improving the flexibility and pertinence of the cleaning operation. The tool's efficient cleaning ability and convenient operability greatly shorten the maintenance time of the slip ring chamber and reduce equipment failures caused by improper cleaning, thereby reducing the overall maintenance cost, ensuring the continuous and stable operation of the generator set, and improving the economic benefits.
[0026] In this embodiment, if Figure 1 As shown, the elastic member is a plurality of springs 12, and the springs 12 are fixed in a compressed state between the two brush plates 2. The elastic member is made directly from the springs 12, which reduces the cost while ensuring the stability of the elastic force, and the production of the tool is more convenient.
[0027] In this embodiment, if Figure 2As shown, the elastic member is an elastic sleeve 13, one end of which is fixed to the edge of the brush plate 2 in an enclosing manner, and the other end is fixed to the negative pressure pipe 1 and encloses around the air inlet 5. The elastic sleeve 13 not only plays the role of propping up the brush plate 2 against the surface of the slip ring, but also forms a channel for negative pressure dust suction through the connecting hole 7 between the brush plate 2 and the negative pressure pipe 1, thereby improving the effect of negative pressure dust suction and increasing the cleaning effect of the slip ring.
[0028] In this embodiment, if Figure 1 , Figure 2 As shown, the connecting frame 3 is arranged in an X shape, and the opening of the slide slot 10 gradually becomes larger toward the end of the connecting frame 3. Pushing the push column 11 toward the front end of the negative pressure tube 1 facilitates the operator to retract the brush plate 2, which is more convenient to use and avoids the safety hazards caused by direct manual cleaning. This design reduces the need for maintenance personnel to enter dangerous areas and improves the safety of operations.
[0029] In this embodiment, if Figure 3 As shown, the top of the negative pressure tube 1 is threadedly connected with a screw rod 14, the top of the screw rod 14 is fixedly connected with a push rod 15, both ends of the push rod 15 are fixedly connected with second bristles 16, and the screw rod 14 is also threadedly connected with a bolt, and the bolt is located between the push rod 15 and the negative pressure tube 1. The screw rod 14 is rotated to adjust the orientation of the second bristles 16, and then the screw rod 14 is fixed with a bolt, so that it is convenient to perform all-round dust removal and cleaning at one time, thereby improving the efficiency of dust removal.
[0030] In this embodiment, if Figure 4 As shown, the brush plate 2 is fixedly connected with a transverse plate 17, the transverse plate 17 is located in the middle of the connecting hole 7, and the first bristles 8 are fixed in an H shape on the transverse plate 17 and the side of the brush plate 2. The first bristles 8 on the middle transverse plate 17 are used to clean the surface of the slip ring back and forth, and the cleaned dust is sucked away by the connecting holes 7 on both sides of the transverse plate 17, so that the operator can use the tool to clean the surface of the slip ring more freely, thereby improving the convenience and cleaning effect of cleaning.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
