Description

Technical Field

[0001] This utility model relates to the field of conductive ring technology, and in particular to a conductive ring with a sealing structure. Background Technology

[0002] Conductive rings play a crucial role in many industrial fields and electronic devices involving conductive connections of rotating parts. From the rotating joints of large industrial machinery, such as the connection between the nacelle and tower of a wind turbine, to the rotating shafts of precision electronic instruments, such as the lens rotation mechanism of high-end camera equipment, conductive rings are needed to achieve stable current transmission and signal transmission.

[0003] In dusty working environments, existing conductive ring products allow dust particles to enter the conductive ring through the gaps in the outer shell, accumulating on the contact surface between the carbon brush needle and the conductive copper ring. This hinders the smooth conduction of current, causing unstable signal transmission and reducing the reliability of equipment operation. Therefore, improvements are needed to address these issues. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conductive ring with a sealing structure, comprising a spliced ​​shell formed by combining two semi-cylindrical shells on the left and right sides, wherein multiple sets of connecting components are provided at the joint of the spliced ​​shells, a first bearing is installed on the inner top surface of the spliced ​​shell, a movable rotating cylinder is sleeved inside the first bearing, multiple conductive copper rings are equidistantly arranged on the movable rotating cylinder, and multiple rotor wires are provided at the top of the movable rotating cylinder.

[0006] Preferably, the bottom end of the splicing housing has multiple stator wires arranged in a ring along the axial side, and one end of each stator wire is fixedly connected to a carbon brush needle, which abuts against multiple conductive copper rings in a corresponding manner.

[0007] Preferably, the connecting assembly includes a plurality of mounting holes symmetrically opened at the connection between the two outer shells, the plurality of mounting holes being evenly arranged on the horizontal circumference of the mating area, and fixing bolts passing through the mounting holes on both outer shells.

[0008] Preferably, a pressing spacer is provided at the joint of the two outer shells, and an annular mounting groove is provided on the top surface of the spliced ​​outer shell, with a clamp sealing ring provided in the annular mounting groove.

[0009] Preferably, an annular sealing gasket is affixed to the top surface of the first bearing, a T-shaped ring block is provided on the top surface of the annular sealing gasket, and a T-shaped ring groove corresponding to the T-shaped ring block is opened on the inner top surface of the spliced ​​housing.

[0010] Preferably, a second bearing ring is sleeved at the bottom end of the movable rotating drum, and multiple rotor wires are fixedly connected to the inner wall of the conductive copper ring one by one.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model effectively prevents dust from entering the conductive ring by using a pressing spacer set at the splicing shell fitting point and a clamp sealing ring in the annular mounting groove on the top surface, thus improving the sealing effect and achieving dustproof function. Furthermore, the cooperation between the annular sealing spacer and its T-shaped ring block on the top surface of the first bearing and the T-shaped ring groove on the top surface of the splicing shell further enhances the sealing performance, reduces dust intrusion, and improves the reliability of the equipment in dusty environments. This ensures the stability of current conduction and signal transmission, and ultimately solves the problem that in dusty working environments, dust particles enter the conductive ring and accumulate on the contact surface between the carbon brush needle and the conductive copper ring, hindering current conduction, causing unstable signal transmission, and reducing the reliability of equipment operation. This significantly improves the stability and reliability of equipment operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5 This utility model discloses a conductive ring with a sealing structure, comprising a spliced ​​outer shell 1 formed by combining two semi-cylindrical outer shells. Multiple connecting components are provided at the joint of the spliced ​​outer shell 1. A first bearing 2 is installed on the inner top surface of the spliced ​​outer shell 1, and a movable rotating cylinder 3 is sleeved inside the first bearing 2. Multiple conductive copper rings 4 are equidistantly arranged on the movable rotating cylinder 3, and multiple rotor wires 5 are provided at the top of the movable rotating cylinder 3. This structure forms the basic framework of the conductive ring. The movable rotating cylinder 3 can rotate within the first bearing 2. The conductive copper rings 4 and rotor wires 5 provide the basis for current transmission and signal transmission, facilitating the conductive connection function of rotating components. Multiple stator wires 8 are arranged in a ring along the axial side at the bottom of the spliced ​​outer shell 1, and a carbon brush is fixedly connected to one end of each stator wire 8. The carbon brush needle 9 and multiple conductive copper rings 4 are connected one-to-one. The contact between the carbon brush needle 9 and the conductive copper rings 4 facilitates the current conduction between the stator conductor 8 and the conductive copper rings 4, improving the stability and reliability of conductivity. This enables stable current transmission and signal transmission. The connecting component includes multiple mounting holes 7 symmetrically opened at the connection of the two shells. The mounting holes 7 are evenly arranged on the horizontal circumference of the mating area. Fixed connecting bolts 10 are passed through the mounting holes 7 on both shells. By passing the fixed connecting bolts 10 through the mounting holes 7, the two shells are firmly connected, improving the connection stability of the spliced ​​shell 1. This ensures the overall stability of the conductive ring structure and prevents the shell from loosening during equipment operation.

[0021] In this utility model, a pressing spacer 12 is provided at the joint of the two outer shells, and an annular mounting groove is provided on the top surface of the spliced ​​outer shell 1. A clamping sealing ring 6 is provided in the annular mounting groove. The cooperation between the pressing spacer 12 and the clamping sealing ring 6 facilitates the enhancement of the sealing performance of the spliced ​​outer shell 1, improves the dustproof and moisture-proof protection effects, and effectively prevents dust and moisture from entering the conductive ring, protecting the normal operation of the internal structure. An annular sealing spacer 11 is attached to the top surface of the first bearing 2, and a T-shaped ring block is provided on the top surface of the annular sealing spacer 11. A T-shaped annular groove corresponding to the T-shaped ring block is opened on the inner top surface of the spliced ​​outer shell 1. The cooperation between the 11 and its T-shaped ring block and T-shaped ring groove further enhances the sealing performance at the first bearing 2, improves the overall sealing effect, and thus better prevents dust, moisture, etc. from entering the interior of the conductive ring from the top, ensuring the stable operation of the conductive ring. The bottom end of the movable rotating drum 3 is fitted with a second bearing ring, and multiple rotor wires 5 are fixedly connected to the inner wall of the conductive copper ring 4 one by one. The second bearing ring facilitates the more stable rotation of the movable rotating drum 3. The fixed connection between the rotor wires 5 and the inner wall of the conductive copper ring 4 improves the efficiency and stability of current conduction, thereby enabling efficient current transmission and signal transmission functions, ensuring the performance of the conductive ring.

[0022] Working principle: When using this utility model, firstly, align and attach the two semi-cylindrical shells pre-installed with the press-fit spacer 12, and tighten the fixing bolts 10 through the mounting holes 7 to form the spliced ​​shell 1. At this time, the press-fit spacer 12 provides initial sealing and ensures the stability of the shell. Next, attach the annular sealing spacer 11 to the top surface of the first bearing 2. After the T-shaped ring block is in place, assemble and install the two together on the inner top surface of the spliced ​​shell 1, allowing the T-shaped ring block to embed into the T-shaped ring groove. Then, fit the movable rotating cylinder 3 into the first bearing 2. Next, install the conductive copper ring 4 on the movable rotating cylinder 3 according to the equidistant requirements using special tools, and reliably connect the rotor wire 5 to the inner wall of the conductive copper ring 4. After that, place the clamp sealing ring 6 into the annular mounting groove on the top surface of the spliced ​​shell 1. Arrange and fix the stator wire 8 along the axial side at the bottom end of the spliced ​​shell 1 using tools such as wire grooves, and connect one end of it to the carbon brush. After connecting the carbon brush needle 9, adjust its position to ensure tight contact with the conductive copper ring 4. Finally, attach a suitable second bearing ring to the bottom of the movable drum 3. During operation, the conductive ring is connected to the circuit to start the device. The movable drum 3 rotates under the support of the first and second bearing rings. Current flows from the external power source through the stator conductor 8 to the carbon brush needle 9, and then to the conductive copper ring 4. Because the conductive copper ring 4 is reliably connected to the rotor conductor 5, the current is ultimately transmitted to the rotor conductor 5, realizing current transmission and signal transmission between rotating and stationary components. At the same time, the pressing spacer 12 at the joint of the splicing shell 1, the clamp sealing ring 6 in the annular mounting groove on the top surface, and the annular sealing spacer 11 on the top surface of the first bearing 2 work together to block dust, moisture, and other impurities, maintaining good contact between the carbon brush needle 9 and the conductive copper ring 4, and ensuring the long-term stable and reliable operation of the conductive ring. Thus, the device is complete.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
