Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a slip ring sealing device. Background Technique

[0002] A slip ring is an electrical component responsible for connecting and transporting energy and signals for a rotating body. The slip ring is usually installed at the rotation center of the device and mainly consists of two major parts: a rotating part and a stationary part. The rotating part is connected to the rotating structure of the device and rotates with it, called the "rotor", and the stationary part is connected to the energy of the fixed structure of the device, called the "stator". After the slip ring is used for a certain period of time, it needs to be maintained. However, during the maintenance process, external floating dust enters the inside of the slip ring, and when it accumulates to a certain amount, it will affect the conductivity of the slip ring.

[0003] In the Chinese patent document with the publication number CN220253719U, a conductive slip ring with self-chip removal and anti-friction of redundant objects is disclosed, including a tube body. Both sides of the outer wall of the tube body are rotatably connected with orifice plates through sealed bearings. The outer wall of the orifice plate is clamped with a first outer shell. The bottom of the first outer shell abuts against a second outer shell clamped with the outer wall of the orifice plate. A conductive ring is wound around the outer wall of the tube body. A brush wire is attached to the top of the conductive ring. The outer wall of the brush wire penetrates through a brush holder fixedly connected to the outer wall of the orifice plate. A brush is attached to the bottom of the conductive ring. The bottom of the brush is fixedly connected to a plastic plate fixedly connected to the inner wall of the second outer shell through a bracket. Through the cooperation of the brush, the bracket, the plastic plate, the orifice plate and the second outer shell, when using the conductive slip ring with self-chip removal and anti-friction of redundant objects, the dust and other waste chips at the contact point can be automatically cleaned and collected.

[0004] The disadvantage of the above disclosed solution is that after the brush has cleaned the dust on the surface of the conductive ring for a long time, a lot of dust will accumulate on the brush, resulting in a poor cleaning effect of the brush on the conductive ring, thereby affecting the conductivity of the conductive ring. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a slip ring sealing device. During the process that the driving component drives the brush to rotate through the brush rod, the dust and impurities on the brush are thrown into the connecting frame under the action of centrifugal force, preventing a lot of dust from accumulating after the brush has cleaned the conductive ring for a long time, and effectively solving the problems in the background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A slip ring sealing device, including a cylinder body, one side of the cylinder body is detachably connected with an orifice plate, a rotor is arranged inside the cylinder body, one end of the rotor is rotatably connected with the cylinder body, the other end of the rotor is rotatably connected with the orifice plate, a plurality of conductive rings are wound around the outer periphery of the rotor, a brush rod is arranged below the conductive rings, bristles are evenly arranged along the circumferential direction of the brush rod, and the bristles are in contact with the conductive rings. A driving component for driving the brush rod to rotate is arranged inside the cylinder body, and a first shell and a second shell are detachably connected to the cylinder body. A plurality of carbon brushes are fixedly arranged inside the first shell, and the plurality of carbon brushes are respectively in contact with the corresponding conductive rings. A connecting frame is fixedly arranged inside the second shell.

[0007] Further, the driving component is a motor, the motor is fixedly installed on one side inside the cylinder body, and the output shaft of the motor is fixedly connected with the brush rod.

[0008] Further, the driving component is a first gear and a second gear. The first gear is fixedly sleeved on the brush rod, the second gear is fixedly sleeved on the rotor, the second gear meshes with the first gear, and one end of the brush rod is rotatably connected with one side inside the cylinder body.

[0009] Further, sealing bearings are arranged on both the orifice plate and the side of the cylinder body away from the orifice plate, and both ends of the rotor are respectively connected with the corresponding sealing bearings.

[0010] Further, there are two connecting frames, the two connecting frames are symmetrically arranged inside the second shell, and the top wall of the connecting frame is in contact with the bristles for scraping the dust on the bristles.

[0011] Further, the orifice plate is connected with the cylinder body by bolts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] Since bristles are evenly arranged along the circumferential direction of the brush rod, the bristles are in contact with the conductive rings, and a driving component for driving the brush rod to rotate is arranged inside the cylinder body. Therefore, starting the motor drives the brush rod to rotate, and the rotation direction of the brush rod is opposite to the rotation direction of the rotor. The brush rod rotates in the reverse direction to clean the dust on the outer wall of the conductive ring, improving the cleaning effect of the brush on the dust on the outer wall of the conductive ring. At the same time, during the rotation of the brush, due to the action of centrifugal force, the dust and impurities are thrown into the connecting frame, avoiding the accumulation of a lot of dust on the brush after the brush has cleaned the conductive ring for a long time. The cleaning effect of the brush on the conductive ring is improved, and thus the conductivity of the conductive ring is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1, please refer to Figures 1-3 , this embodiment provides a technical solution: a slip ring sealing device, including a cylinder body 1, one side of the cylinder body 1 is detachably connected with an orifice plate 2, and the orifice plate 2 is connected with the cylinder body 1 through a bolt 13. Four threaded holes are provided along the circumference of one side of the orifice plate 2, and the bolt 13 is matched with the threaded hole and threadedly connected with one side of the cylinder body 1.

[0022] A rotor 4 is horizontally installed in the cylinder body 1 along the length direction of the cylinder body 1, one end of the rotor 4 is rotatably connected with the cylinder body 1, and the other end of the rotor 4 is rotatably connected with the orifice plate 2. Through holes are provided at the center of the orifice plate 2 and at the center of the side of the cylinder body 1 away from the orifice plate 2, and the centers of the through holes coincide with the axis of the cylinder body 1. A sealed bearing 3 is fixedly installed in the through hole, and both ends of the rotor 4 are fixedly and cooperatively installed with the inner rings of the corresponding sealed bearings 3. This facilitates the rotation of the rotor 4 while preventing dust from entering the interior of the cylinder body 1.

[0023] A plurality of conductive rings 12 are wound around the outer periphery of the rotor 4. A brush rod 6 is installed below the conductive rings 12. A plurality of rows of bristles are installed on the brush rod 6 in a circumferential array along it, and each row of bristles is evenly arranged along the length direction of the brush rod 6. The bristles are in contact with the conductive rings 12. A driving component for driving the brush rod 6 to rotate is installed in the cylinder body 1. The driving component is a motor 5. The motor 5 is fixedly installed on one side inside the cylinder body 1, and the output shaft of the motor 5 is fixedly connected to the brush rod 6 coaxially.

[0024] Openings are provided on both the upper and lower sides of the outer periphery of the cylinder body 1. A first housing 7 and a second housing 10 are detachably connected to the openings on the upper and lower sides of the cylinder body 1 through bolts 13 respectively. Sealing gaskets 8 are installed at the openings of the first housing 7 and the second housing 10 and the cylinder body 1 to increase the sealing performance of the cylinder body 1. A plurality of carbon brushes 9 are fixedly installed on the inner side of the first housing 7. The plurality of carbon brushes 9 are respectively in contact with the corresponding conductive rings 12. The first housing 7 can be removed through the bolt 13 to replace the carbon brushes 9. Two connecting frames 11 are fixedly installed on the inner side of the second housing 10. The two connecting frames 11 are symmetrically arranged on the inner side of the second housing 10. The top wall of the connecting frame 11 is in contact with the bristles and is used for scraping the dust on the bristles.

[0025] The working principle of a slip ring sealing device provided in this embodiment is as follows:

[0026] After the slip ring is installed in a suitable position, it can be put into use. When the rotor 4 rotates, the brushes on the brush rod 6 contact the outer wall of the conductive ring 12, thereby cleaning the dust on the outer wall of the conductive ring 12. Since the brushes remain stationary for a long time, a lot of dust is likely to accumulate on the brushes, affecting the cleaning effect of the brushes on the conductive ring 12. At this time, start the motor 5 to drive the brush rod 6 to rotate, and make the rotation direction of the brush rod 6 opposite to the rotation direction of the rotor 4. The brush rod 6 rotates to clean the dust on the outer wall of the conductive ring 12, improving the cleaning effect of the brushes on the dust on the outer wall of the conductive ring 12. During the rotation of the brushes, due to the action of centrifugal force, the dust and impurities are thrown into the connecting frame 11, and the connecting frame 11 collects the dust. The second housing 10 can be removed through the bolt 13 to pour out the dust in the connecting frame 11.

[0027] At the same time, during the rotation of the brushes, they contact the top wall of the connecting frame 11. The top wall plays a role in scraping the dust and impurities on the brushes, preventing the continuous accumulation of dust on the brushes, and further improving the cleaning effect of the brushes on the dust on the outer wall of the conductive ring 12.

[0028] Embodiment Two, please refer to Figures 4-5, the difference between this embodiment and the first embodiment is that: the driving components are the first gear 14 and the second gear 15. The first gear 14 is fixedly sleeved on the brush rod 6, and the second gear 15 is fixedly sleeved on the rotor 4. The second gear 15 meshes with the first gear 14, and the transmission ratio of the first gear 14 to the second gear 15 is 1:3, that is, when the second gear 15 rotates one circle, the first gear 14 rotates three circles. One end of the brush rod 6 is rotatably and cooperatively installed on one side inside the cylinder body 1.

[0029] The differences in the working principles between this embodiment and the first embodiment are as follows:

[0030] The rotation of the rotor 4 drives the second gear 15 to rotate. The second gear 15 drives the first gear 14 to rotate in the opposite direction. The first gear 14 drives the brush rod 6 to rotate in the direction opposite to the rotation direction of the rotor 4. The brush rod 6 drives the brush to clean the dust on the outer wall of the slip ring 12.
