Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically to an integrated generator rotor carbon powder collection device. Background Technology

[0002] The generator rotor is a key component of the generator, with a precise and complex structure. The shaft, made of high-strength alloy steel, is the core support of the entire rotor, stably bearing its own weight and the mechanical and electromagnetic stresses during operation, ensuring smooth rotor rotation. The magnetic yoke, made of laminated silicon steel sheets with excellent magnetic permeability, is fixed to the shaft, constructing the magnetic circuit for the rotor's magnetic field and serving as the base for mounting the magnetic poles. The magnetic poles are crucial for generating the magnetic field; excitation windings are wound around them, and a magnetic field is generated when a direct current is applied. Common magnetic pole shapes include salient poles and non-salient poles. Slip rings are mounted on the shaft and connected to the excitation winding leads. Carbon brushes contact the surface of the slip rings, thereby introducing external DC power into the excitation windings. During operation, the prime mover drives the rotor to rotate, and the magnetic poles rotate accordingly, generating alternating magnetic flux in the stator windings. According to the law of electromagnetic induction, an electromotive force is induced in the stator windings, and when connected to an external circuit, electrical energy is output. Therefore, the generator rotor not only generates a magnetic field but also transmits mechanical energy, making it the core element for the generator to achieve electrical energy conversion.

[0003] The generator rotor excitation is conducted through graphite carbon brushes. When the rotor rotates, due to friction with the graphite carbon brushes, fine carbon powder is generated and accumulates in the generator slip rings. Over time, this accumulation reduces the insulation of the generator rotor and endangers the normal operation of the generator set. In the existing technology, the carbon powder is handled by using tools such as brushes and scrapers to periodically clean the carbon powder inside and on the surface of the generator.

[0004] The cleaning process is inefficient, requiring manual operation bit by bit. It is time-consuming and labor-intensive to deal with large areas of carbon powder accumulation, such as deep in the slip ring and in the winding gaps, which can cause carbon powder residue. Long-term accumulation may still affect the operation of the equipment and make it impossible to efficiently process the carbon powder. To address the above problems, an integrated generator rotor carbon powder collection device is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Refer to Figure 3 and Figure 4 This utility model discloses an integrated generator rotor toner collection device, including a collector ring 1, which is installed on the rotor shaft of a generator motor. A dust collection chamber 21 is provided on one side of the inner wall of a protective shell 2. The inner wall of the protective shell 2 is provided with evenly distributed dust collection ports 19. The toner enters the dust collection chamber 21 through the dust collection ports 19. A mounting plate 18 is slidably connected to the top of the ring brush plate 13. The mounting plate 18 can connect two ring brush plates 13. Bolts 20 are provided on the top of the mounting plate 18. The mounting plate 18 can be easily disassembled by rotating the bolts 20.

[0034] Reference Figure 1 and Figure 2The outer ring of the collector ring 1 is slidably connected to a protective shell 2. A sealing plate 5 is fixedly connected to one side of the protective shell 2. The sealing plate 5 of one side of the protective shell 2 can be inserted into the protective shell 2 of the other side. The protective shell 2 is bolted to the motor housing. A first spring 6 is fixedly connected to the inner wall of the sealing plate 5. A buckle 7 is fixedly connected to one end of the first spring 6. The buckle 7 on one side pops out from the groove of the protective shell 2, which facilitates the fixation of the protective shell 2. A vacuum hose 4 is passed through and fixedly connected to the outer ring of the protective shell 2. An air blower is passed through and fixedly connected to the top of the protective shell 2. The air hose 3 is driven by an external fan to deliver airflow. The top and bottom of the inner wall of the protective shell 2 are fixedly connected with sealing gaskets 8, which seal the gaps between the protective shell 2 and the top and bottom of the collector ring 1. The outer ring of the protective shell 2 is fixedly connected with a micro motor 9, and the output end of the micro motor 9 is fixedly connected with a first bevel gear 10. The micro motor 9 drives the first bevel gear 10 to rotate. The bottom of the inner wall of the protective shell 2 is rotatably connected with a lead screw 12, and a cleaning component is provided on the bottom outer ring of the lead screw 12.

[0035] Reference Figure 4 The cleaning assembly includes a ring brush plate 13, which is threadedly connected to the outer ring of a lead screw 12. The rotation of the lead screw 12 causes the ring brush plate 13 to move up and down, and the ring brush plate 13 can wipe the suction port 19 to prevent the suction port 19 from being blocked. A ring plate 14 is fixedly connected to the inner wall of the ring brush plate 13, and the top of the ring plate 14 is connected to one end of the air blowing hose 3. The air blowing hose 3 expands and contracts according to the up and down movement of the ring plate 14. A uniformly distributed second spring 15 is fixedly connected to the inner wall of the ring plate 14. An arc-shaped brush plate 17 is fixedly connected to one end of the second spring 15. The second spring 15 is always in a compressed state. A uniformly distributed air blowing pipe 16 is connected to the inner wall of the arc-shaped brush plate 17. The airflow blows the outer ring of the collector ring 1 through the air blowing pipe 16. A second bevel gear 11 is fixedly connected to the bottom of the lead screw 12, and the second bevel gear 11 is meshed with the first bevel gear 10.

[0036] Working principle: First, during the disassembly of the protective shell 2, pressing the buckle 7 compresses the first spring 6, then sliding the protective shell 2 allows it to be disassembled. Next, rotating the bolt 20 disassembles the mounting plate 18, thus allowing the ring plate 14 and the ring brush plate 13 to be separated. An external exhaust fan and blower ensure airflow through the air blowing hose 3 and separate the dust suction hose 4, facilitating toner collection. When toner collection is needed, the micro motor 9 drives the first bevel gear 10 to rotate, causing the second bevel gear 11 to drive the lead screw 12. Rotation allows the ring brush plate 13 to move the ring plate 14 up and down. The second spring 15 is released under pressure, allowing the arc-shaped brush plate 17 to adhere tightly to the outer wall of the collector ring 1 and wipe it. During the wiping process, airflow is delivered to the ring plate 14 through the air blowing hose 3, and then the carbon powder accumulated on the collector ring 1 is sprayed through the air blowing pipe 16, causing the carbon powder to fly. The flying carbon powder is extracted from the dust suction hose 4 through the cooperation between the dust suction port 19 and the dust suction chamber 21, thereby effectively collecting and processing the carbon powder generated in the generator collector ring 1, ensuring that the carbon powder does not accumulate inside the equipment.
