Description

Technical Field

[0001] This invention belongs to the field of toner collection technology, specifically relating to a toner collection device for a horizontal unit. Background Technology

[0002] Hydroelectric generator sets generate electricity using the principle of induced electromotive force generated by coils cutting magnetic fields. The current collector is a crucial component, primarily composed of slip rings and carbon brushes. During operation, DC power is transmitted through the carbon brushes and slip rings to the excitation windings on the rotor, generating a magnetic field. The coils are located on the stator. As the rotor rotates around the stator with the excitation windings, the coils on the stator cut magnetic lines of force, generating current. During operation, friction inevitably occurs between the slip rings (which rotate at high speed) and the stationary carbon brushes. This friction causes carbon dust to form on the carbon brushes, which then settles on the insulating supports between the positive and negative terminals of the slip rings, leading to a decrease in rotor insulation.

[0003] The existing horizontal hydro-generator excitation system's slip ring section lacks a carbon dust collection device. After prolonged operation, dust is generated by the friction between the slip ring and carbon brushes. Since the slip ring requires ventilation and cooling, its protective cover is not fully enclosed, allowing carbon dust to scatter throughout the unit through its openings. If not cleaned promptly, the rotor insulation will fail to meet technical requirements, and the safe operation of automation components will also be affected. Given that adding a carbon dust absorption device can effectively absorb the carbon dust scattered within the protective cover, preventing a decline in rotor insulation and solving the ventilation and heat dissipation problem, installing a carbon dust collection device on the hydro-generator is extremely important. Existing horizontal unit carbon dust absorption devices often only extract air, and the extracted air contains relatively little carbon dust, resulting in low extraction efficiency. Therefore, a carbon dust collection device and unit cooling structure for a hydro-generator are proposed.

[0004] To address the aforementioned issues, utility model CN219893140U discloses a carbon powder collection device and a unit cooling structure for a hydro-turbine generator set. The carbon powder collection mechanism includes an assembly plate with symmetrically arranged movable slots at its center. Each movable slot contains an I-shaped plate, and the inner sidewalls of the I-shaped plates are fitted with protective covers. Each of the two protective covers has observation windows on its sidewalls and a blowing fan on its top. The right protective cover is connected to a dust removal device via a connecting pipe. Engine carbon brush rings are located inside the two protective covers. A support mechanism is located below the assembly plate. The utility model also includes a hydro-turbine generator assembly, comprising a base. A hydro-turbine, a motor, and a conversion device are arranged on the upper surface of the base. The output shaft of the hydro-turbine is connected to the motor, and the output shaft of the motor is connected to the conversion device. The engine carbon brush rings are mounted on the output shaft of the motor.

[0005] While the aforementioned existing technology has solved the problems of the existing technology, its structure is designed for a generator. While the generator generates electricity, it also requires the use of a separate purging fan to consume electrical energy. Many people consider this a waste of resources. Therefore, it is necessary to change this method of toner collection. Summary of the Invention

The connecting wing plates on both sides of the two semi-circular clamps are locked by the cooperation of a second bolt and a second nut. Multiple limiting strips are distributed on the inner wall of one end of each semi-circular clamp. The inner wall of the other end of the connecting sleeve fastening ring is a conical structure with an inner diameter that gradually decreases from one end of the connecting sleeve fastening ring to the other end.

Detailed Implementation

[0027] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0028] Example:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a toner collection device for a horizontal generator set, including an output shaft positioning mechanism, a protective cover 2, a blowing fan blade 7, and a transmission mechanism. The protective cover 2 is sealed and fitted over the engine carbon brush ring 3, which is connected to the motor output shaft 1. The lower end of the protective cover 2 is connected to a toner discharge channel 4. One side of the toner discharge channel 4 is connected to a dust removal device 6 through a connecting pipe 5. This allows the toner raised by the engine carbon brush ring 3 during operation to fall into the toner discharge channel 4 under the constraint of the protective cover 2, and then enter the dust removal device 6 through the connecting pipe 5 to achieve toner processing. The dust removal device 6 can adopt existing technology.

[0030] To achieve the above solution, an air inlet channel is provided on the other side of the toner feeding channel 4 opposite to the connecting pipe 5. The blowing fan blade 7 is installed in the air inlet channel to blow the toner falling into the toner feeding channel 4 into the connecting pipe 5. During the operation of the engine carbon brush ring 3, the blowing fan blade 7 will generate an airflow, thereby blowing the toner falling into the toner feeding channel 4 into the connecting pipe 5, and then into the dust removal device 6. Moreover, the airflow generated by the blowing fan blade 7 can also form an adsorption effect on the toner in the protective cover 2, so that the toner is blown into the connecting pipe 5 more efficiently. The wind speed generated by the blowing fan blade 7 can be set according to the actual situation and is not specifically limited.

[0031] Meanwhile, in order to provide power to the brush 7, the output shaft positioning mechanism is detachably connected to the motor output shaft 1, and the output shaft positioning mechanism can rotate under the drive of the motor output shaft 1. Thus, when the horizontal unit is working, the rotation of the motor output shaft 1 can drive the output shaft positioning mechanism to rotate. The first central shaft 701 of the brush 7 extends to the outside of the air inlet channel and is connected to the output shaft positioning mechanism through a transmission mechanism. When the motor output shaft 1 rotates, the output shaft positioning mechanism can drive the brush 7 to rotate through the transmission mechanism. The rotation of the brush 7 can form an airflow that blows the carbon powder in the carbon powder feeding channel 4 into the connecting pipe 5. Thus, there is no need to connect to a separate power supply and consume electrical energy. The wind force for carbon brush blowing can be achieved by the rotation of the motor output shaft 1, which saves resources to a certain extent.

[0032] This invention features a detachable output shaft positioning mechanism connected to the motor output shaft 1. During operation, the horizontal unit utilizes the motor output shaft 1 to drive the output shaft positioning mechanism, which in turn controls the transmission mechanism. This transmission mechanism transmits force to the blowing fan blades 7, causing the blowing fan blades 7 to generate a force that blows towards the connecting pipe 5 within the air inlet channel. When the engine carbon brush ring 3 is operating, the carbon dust raised can efficiently enter the connecting pipe 5 using the force generated by the blowing fan blades 7, and then proceed to the dust removal device 6 for processing. This eliminates the need for a separate power supply and energy consumption for the blowing fan blades 7; the rotation of the motor output shaft 1 is sufficient to generate the blowing force for carbon brush cleaning, thus saving resources to a certain extent.

[0033] As a preferred embodiment of this invention, it should be further explained that the output shaft positioning mechanism includes an output shaft connecting sleeve 8 and two connecting sleeve fastening rings 9, both sleeved around the motor output shaft 1. Multiple wedge-shaped elastic blocks 801 are provided at both ends of the output shaft connecting sleeve 8. The two connecting sleeve fastening rings 9 are slidably connected to the outside of the output shaft connecting sleeve 8, and the inner walls of the two connecting sleeve fastening rings 9 abut against the elastic blocks 801, causing the elastic blocks 801 to rub against and adhere tightly to the motor output shaft 1. In practice, as the connecting sleeve fastening rings 9 slide outside the output shaft connecting sleeve 8, the elastic blocks 801 can be compressed. 01 or the compression of the elastic block 801 by the contact. When the connecting sleeve fastening ring 9 compresses the elastic block 801, the elastic block 801 is tightly attached to the motor output shaft 1, and a large frictional force is formed between it and the motor output shaft 1. When the motor output shaft 1 rotates, the elastic block 801 can drive the entire output shaft positioning mechanism to rotate. The ends of the two connecting sleeve fastening rings 9 that are close to each other are locked by the cooperation of the first bolt and the first nut. Through the cooperation of the first bolt and the first nut, the large frictional force between the elastic block 801 and the motor output shaft 1 can be further increased and kept stable.

[0034] As a preferred embodiment of this invention, it should be further explained that the output shaft connecting sleeve 8 includes two semi-circular connecting rings 802 that can be spliced ​​into a connecting ring. The semi-circular connecting rings 802 are located in the middle of the output shaft connecting sleeve 8. The connecting ring is sleeved on the outside of the motor output shaft 1, and each semi-circular connecting ring 802 has multiple elastic blocks 801 connected to both ends, thereby realizing the sleeve of the output shaft connecting sleeve 8 on the outside of the motor output shaft 1. The distance between the elastic block 801 and the motor output shaft 1 is from its distance from the semi-circular connecting ring 802. 02 The connection gradually narrows from one end to the other, making it easier to press the elastic block 801 with the fastening ring 9 of the connecting sleeve; the outer wall of the sleeve ring has a plurality of grooves evenly distributed along its circumference, and the grooves extend along the length of the sleeve ring. The inner wall of one end of the fastening ring 9 has a plurality of limiting strips evenly distributed, and each limiting strip is slidably connected in a groove, so that the fastening ring 9 of the connecting sleeve can slide stably outside the output shaft connecting sleeve 8, which also makes the connection of the two fastening rings 9 easier.

[0035] As a preferred embodiment of this example, it should be further explained that the connecting sleeve fastening ring 9 includes two semi-circular clamps, which are spliced ​​together to form a circular clamp. Connecting wing plates 901 are provided on both sides of the two semi-circular clamps. The connecting wing plates 901 on both sides of the two semi-circular clamps are locked by the cooperation of a second bolt and a second nut, facilitating the installation and removal of the connecting sleeve fastening ring 9 outside the motor output shaft 1. Multiple limiting strips are distributed on the inner wall of one end of each semi-circular clamp to facilitate the sliding limitation of the connecting sleeve fastening ring 9 outside the output shaft connecting sleeve 8. The inner wall of the other end of the connecting sleeve fastening ring 9 is a conical structure with an inner diameter that gradually decreases from one end to the other. Through the holes in the conical structure, the other end of the elastic block 801 can be squeezed. As the two connecting sleeve fastening rings 9 get closer to each other, the pressure on the elastic block 801 increases, allowing the entire output shaft positioning mechanism to be more stably connected to the outside of the motor output shaft 1.

[0036] As a preferred embodiment of this invention, it should be further explained that each of the two connecting sleeve fastening rings 9 has an outwardly protruding annular connecting plate 902 at one end closest to each other. The two annular connecting plates 902 are locked together by the cooperation of a third bolt and a third nut, thereby achieving a quick connection between the two annular connecting plates 902. Preferably, the annular connecting plate 902 and the connecting wing plate 901 are integrally formed to ensure the strength and stability of the structure. The transmission mechanism includes a first gear 10 fixed in the middle of the output shaft connecting sleeve 8, which drives the first gear 10 to rotate through the output shaft connecting sleeve 8, thereby enabling the transmission mechanism to rotate. The structure can drive the blowing fan blade 7 to rotate, realizing power transmission; the first gear 10 is located between two annular connecting plates 902, and a through hole is opened on the first gear 10. The third bolt passes through the through hole, and when the two connecting wing plates 901 are locked, there is still a gap between the connecting wing plate 901 and the first gear 10, so as to ensure that the elastic block 801 can be more stably frictionally connected with the motor output shaft 1; the first gear 10 is divided into two semi-circular gears, and the two semi-circular gears are respectively fixed outside the two semi-circular sleeve rings 802, which does not affect the use of the first gear 10 or the installation and removal of the output shaft connecting sleeve 8.

[0037] As a preferred embodiment of this invention, it should be further explained that the transmission mechanism includes a first gear 10, a second gear 11, a third gear 12, and a fourth gear 13. The first gear 10 meshes with the second gear 11, the second gear 11 is coaxially connected with the third gear 12, and the third gear 12 meshes with the fourth gear 13. Both the third gear 12 and the fourth gear 13 are bevel gears. The fourth gear 13 is coaxially connected with the first central shaft 701 of the blowing fan blade 7. The transmission method is simple and convenient. When the first gear 10 rotates, it drives the second gear 11 to rotate. The second gear 11 drives the coaxially connected third gear 12 to rotate. The third gear 12 then drives the fourth gear 13 to rotate, so that the fourth gear 13 can form a vertical transmission force on one side of the protective cover 2. This facilitates the coaxial connection of the fourth gear 13 with the blowing fan blade 7 through the first central shaft 701, providing power for the rotation of the blowing fan blade 7.

[0038] As a preferred embodiment of this invention, it should be further explained that the second gear 11 and the third gear 12 are coaxially mounted on the second central shaft, and one end of the second central shaft is rotatably connected to the motor base 14 to ensure the stability of the second gear 11 and the third gear 12. Of course, in practice, they can also be simultaneously mounted on other equipment, such as bearing housings, to further ensure the stability of the second gear 11 and the third gear 12. The first central shaft 701 is detachably connected to the air inlet of the air inlet channel to ensure the stability of the first central shaft 701, thereby ensuring the stability of the blowing fan blade 7 and the fourth gear 13.

[0039] As a preferred embodiment of this invention, it should be further explained that an installation groove is provided at the air inlet of the air inlet channel. A ball bearing 15 is installed in the middle of the first central shaft 701. The inner ring of the ball bearing 15 is fixedly connected to the middle of the first central shaft 701. The two ends of the ball bearing 15 abut against a first bracket 16 and a second bracket 17, respectively. The first bracket 16 is slidably installed in the installation groove, and the second bracket 17 is detachably connected to the outside of the air inlet channel, thereby ensuring the stability of the ball bearing 15 and also ensuring the stability and flexibility of the first central shaft 701. It should be noted that the second bracket 17 can be detachably connected to the outside of the air inlet channel by bolts or by a snap-fit ​​structure, etc. This embodiment does not impose specific limitations.

[0040] As a preferred embodiment of this invention, it should be further explained that the first bracket 16 includes a first central ring and first positioning rods evenly distributed on the outer wall of the first central ring. The first positioning rods are slidably disposed at the bottom of the mounting groove to ensure the stability of the first bracket 16. One end of the ball bearing 15 abuts against the first central ring, and the first central ring is provided with a first snap-fit ​​groove that engages with the outer ring of the ball bearing 15, ensuring the stability of the ball bearing 15 without affecting the flexibility of the first central shaft 701. The second bracket 17 includes a second central ring and a third central ring sleeved outside the second central ring (for easy detachable connection by bolts or snap-fit ​​structures). The third central ring is detachably connected to the outside of the air inlet channel. The third central ring is connected to the second central ring through multiple second positioning rods to ensure the stability of the second bracket 17. The second central ring is provided with a second snap-fit ​​groove that engages with the outer ring of the ball bearing 15, ensuring the stability of the ball bearing 15 without affecting the flexibility of the first central shaft 701.

[0041] As a preferred embodiment of this example, it should be further explained that one end of the connecting pipe 5 is connected to the toner feeding channel 4 through a reducing pipe, the air inlet channel is inclined, and the air outlet of the air inlet channel is inclined downward and aligned with the inlet of the reducing pipe, so that the toner can enter the connecting pipe 5 more smoothly.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
