Abstract
Description
Technical Field
[0001] This application relates to the field of waste incineration power generation equipment technology, and more specifically, to a slip ring device. Background Technology
[0002] In the booming development of the modern waste-to-energy industry, waste lifting motors, as core transfer equipment, play a crucial supporting role in ensuring the continuity of the entire production process. However, current waste-to-energy plants are plagued by slip ring system failures, with insulation problems being particularly prominent.
[0003] Inside a waste-to-energy plant, humidity is often high, dust fills the air, high temperatures and heat waves constantly bombard the environment, and various corrosive substances are rampant. Under such harsh conditions, the shortcomings of the original slip ring design for the waste crane lifting motor become apparent.
[0004] The key issue lies in the insulation ring, which suffers from severely inadequate insulation. The initial design failed to adequately consider the potential threats posed by high-voltage surges, frequent electric field changes, and complex media in the actual operating environment. When the motor operates for extended periods, with high-voltage current continuously flowing through the slip ring system, the insulation ring struggles to withstand the pressure and is highly susceptible to breakdown at rated voltage. Once this breakdown occurs, creepage occurs, instantly triggering a phase-to-phase short circuit in the slip ring. The powerful short-circuit current directly burns out the slip ring, causing the entire hoisting motor to stop abruptly, forcing a production interruption, and resulting in significant safety hazards and economic losses.
[0005] Therefore, how to design a slip ring device to increase insulation performance, eliminate creepage, and avoid slip ring burnout is an issue that needs attention. Utility Model Content
[0006] In view of the above problems, this application provides a slip ring device to increase insulation performance, eliminate creepage, and avoid slip ring burnout failure.
[0007] To achieve the above objectives, the following specific solutions are proposed:
[0008] A slip ring device includes: an axial slip ring and a contact carbon brush;
[0009] The axial slip ring includes a brush, a slip ring body, and multiple conductive rings. The multiple conductive rings are mounted on the rotating part of the slip ring device, and the brush is in contact with the slip ring body.
[0010] The contact carbon brush contacts the axial slip ring, and an epoxy resin insulator is arranged at the end of the contact carbon brush that contacts the axial slip ring. The epoxy resin insulator has a specification larger than a preset specification.
[0011] Optionally, the slip ring device may also include an aluminum alloy ring structure;
[0012] The aluminum alloy ring structure encloses the slip ring body to form the outer shell of the slip ring body.
[0013] Optionally, the slip ring device may also include a seal;
[0014] The seal is installed on the outer ring of the annular structure.
[0015] Optionally, the slip ring device may also include a retainer;
[0016] The fixing member secures the slip ring body to the rotating shaft of the slip ring device.
[0017] Optionally, the slip ring device may also include an insulating support rod;
[0018] One end of the contact carbon brush is fixed to the insulating support rod, and the other end is in contact with the axial slip ring.
[0019] Optionally, the brush holder of the contact carbon brush is spring-loaded.
[0020] Optionally, the carbon brush in contact with the carbon brush is carbon graphite with a metal-coated surface.
[0021] The optional contact carbon brush may include a spring, a contact plate, and a fastener.
[0022] Optionally, the slip ring body is made of a copper alloy.
[0023] Optionally, it also includes a flange, which is fixed to the axial slip ring by a flange fastener.
[0024] By employing the above technical solution, this application establishes a contact carbon brush in the slip ring device that contacts the axial slip ring. An epoxy resin insulator is arranged at the end of the contact carbon brush that contacts the axial slip ring, and the epoxy resin insulator's specifications are larger than a predetermined specification. Therefore, the contact brush, made of carbon, possesses excellent wear resistance and stability, ensuring stable long-term operation of the slip ring. The insulator isolates the metal and non-metal parts, guaranteeing the safe operation of the slip ring. Furthermore, the use of an epoxy resin insulator with good mechanical strength and electrical insulation properties allows it to withstand the high-intensity environment of waste incineration power generation. Simultaneously, the increased size, thickness, and width of the insulator effectively reduce creepage effects, prevent short circuits, and avoid slip ring burnout. Attached Figure Description

Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:

[0028] Figure 3 This is a top view of the device structure of a slip ring device provided in an embodiment of this application. Detailed Implementation
[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Figures 1-3 An optional structure of the slip ring device provided in the embodiments of this application, such as Figures 1-3 As shown, the slip ring device may include an axial slip ring and a contact carbon brush.
[0031] Specifically, an axial slip ring may include a brush, a slip ring body, and multiple conductive rings. The multiple conductive rings are mounted on the rotating part of the slip ring assembly. The brush is in contact with the slip ring body.
[0032] The conductive ring, mounted on the rotating part, is responsible for carrying high current. The brush, made of a highly conductive metal material, transmits electrical signals through contact with the slip ring. The slip ring body can be made of a copper alloy with good conductivity to reduce contact resistance and improve wear resistance on its surface.
[0033] Furthermore, the carbon brush in contact with the carbon brush is carbon graphite with a metal-coated surface.
[0034] Understandably, in traditional slip ring mechanisms, when current passes through the slip ring, the contact resistance increases, and according to Joule's law, the more heat is generated by the resistance. Under high current conditions, an electric spark effect is easily generated. This spark not only leads to energy loss but also corrodes and wears the contact material of the slip ring, reducing its contact performance and further increasing contact resistance, creating a vicious cycle. The contact carbon brushes of the slip ring device in this application are made of carbon graphite, and their conductivity is close to that of metal, ensuring stable current transmission from the motor.
[0035] Understandably, there is relative movement between the brush and the conductive ring in a traditional slip ring, which generates friction. Under high current and high speed operating conditions, friction and wear become even more severe. The slip ring device of this application has a metal plating on the surface of the contact carbon brush, which can improve wear resistance and effectively extend the service life of the motor.
[0036] Furthermore, the contact carbon brush contacts the axial slip ring, and an epoxy resin insulator is arranged at the end of the contact carbon brush that contacts the axial slip ring. The epoxy resin insulator has a specification larger than a preset specification.
[0037] Specifically, such as Figure 2 As shown, the contact carbon brush can consist of two parts: one part consists of multiple control power contact carbon brushes, and the other part consists of multiple power power contact carbon brushes. Each control power contact carbon brush can contact the front section of the axial slip ring, and each power power contact carbon brush can contact the rear section of the axial slip ring.
[0038] Understandably, insulators are components used to isolate metallic and non-metallic parts, ensuring the safe operation of the slip ring device. Epoxy resin materials possess excellent mechanical strength and electrical insulation properties, making them suitable for applications requiring high strength and good insulation. Furthermore, high-performance insulating materials can be used for isolation between multiple conductive rings and between the conductive rings and the slip ring housing. Enlarging, thickening, and widening the insulator can effectively reduce creepage effects and prevent short circuits. In addition, the slip ring, through contact with a carbon brush, replaces the traditional cable connection method, reducing cable wear and failures and extending the equipment's service life.
[0039] Furthermore, the slip ring device of this application may also include an aluminum alloy ring structure. The aluminum alloy ring structure encloses the slip ring body to form the outer shell of the slip ring body.
[0040] Understandably, aluminum alloy, with its high strength and wear resistance, provides excellent support and protects internal components from damage when used as the outer shell of a slip ring. The lower density of the aluminum alloy ring structure makes it lighter than other metals, facilitating installation and use. The moderate strength of the aluminum alloy ring structure meets the mechanical performance requirements of the slip ring while ensuring its durability and stability. Furthermore, its excellent thermal conductivity aids in heat dissipation, effectively reducing the operating temperature of the slip ring and extending its service life in high-temperature, hot environments.
[0041] Furthermore, the slip ring device of this application may also include a seal. The seal may be installed on the outer ring of the annular structure.
[0042] Understandably, seals prevent water, dust, and other debris from entering the slip ring assembly, reducing its failure rate. They physically isolate the slip ring from external contaminants. The seal design effectively prevents dust, moisture, and other impurities from corroding the internal structure of the slip ring, ensuring its stability and reliability during long-term operation. Using seals ensures stable operation in landfill environments, reducing maintenance and replacement frequency, thus minimizing the impact of the external environment on the slip ring's internal structure, extending its service life, and improving durability. In harsh environments, seals effectively protect the slip ring assembly, ensuring stable operation and enhancing reliability.
[0043] Furthermore, the slip ring device of this application may also include a fixing member. The fixing member can fix the slip ring body to the rotating shaft of the slip ring device.
[0044] Understandably, the slip ring needs to be fitted with a fixing component to be fixed on the machine's rotating shaft. This completely avoids slip ring vibration, thereby fundamentally eliminating the sparking caused by traditional slip ring vibration and ensuring rotational stability.
[0045] Furthermore, the brush holder that contacts the carbon brush can be spring-loaded.
[0046] Understandably, the spring-loaded brush grip design ensures stable contact pressure and good sliding characteristics.
[0047] Furthermore, the carbon brush that contacts the carbon brush may include a spring, a contact plate, and a fastener.
[0048] Understandably, carbon brushes containing springs, contact plates, and fasteners are better able to slide on the conductive ring and maintain electrical contact with the commutator.
[0049] Furthermore, the slip ring device of this application may also include an insulating support rod and several flanges.
[0050] Specifically, one end of the carbon brush is fixed to the insulating support rod, and the other end is in contact with the axial slip ring.
[0051] like Figure 2 As shown, Figure 2 An insulating support rod is provided above and below the device to form a double bearing support structure. The fixed end of each control power contact carbon brush or each power contact carbon brush is fixed to any one of the insulating support rods, and the other end is in contact with the axial slip ring.
[0052] Each flange can be secured to the axial slip ring using flange fasteners.
[0053] Understandably, the slip ring device uses dual bearing support and electric flange buffer, which further reduces vibration and arcing, adapts to high linear speed operation, and significantly extends brush life.
[0054] The slip ring device provided in this embodiment involves contact between a contact carbon brush and an axial slip ring. An epoxy resin insulator is arranged at the end of the contact carbon brush that contacts the axial slip ring, and the epoxy resin insulator's specifications are larger than a preset specification. Therefore, the contact brush, made of carbon, has good wear resistance and stability, ensuring stable operation of the slip ring over a long period. The insulator isolates the metal and non-metal parts, ensuring safe operation of the slip ring. Furthermore, the use of an epoxy resin insulator with good mechanical strength and electrical insulation properties allows it to adapt to the high-intensity environment of waste incineration power generation. The increased size, thickness, and width of the insulator effectively reduce creepage effects, prevent short circuits, and avoid slip ring burnout.
[0055] Furthermore, the slip ring technology employed in the slip ring device of this application allows the X-ray tube to rotate continuously in one direction while simultaneously powering and transmitting signals through the slip ring.
[0056] Furthermore, the slip ring device of this application achieves efficient data transmission between rotating and stationary components. Compared to traditional wired transmission methods, slip ring technology eliminates the need for complex cables and connectors on rotating components, allowing the device to rotate 360 degrees without restriction, without affecting signal or power transmission. This avoids transmission efficiency degradation caused by cable tangling, wear, and other issues, reduces equipment maintenance frequency, ensures data real-time performance and accuracy, and significantly improves equipment flexibility and reliability.
[0057] Furthermore, the slip ring device of this application can adapt to various complex installation environments, such as rotating machinery and robots. In addition, the interface design of slip ring technology is characterized by universality and standardization, which can seamlessly interface with a variety of equipment and systems, further improving its application flexibility and convenience.
[0058] Furthermore, the slip ring device of this application is designed based on the requirements of use in harsh environments, thus possessing higher sealing performance and wear resistance, and can operate stably in harsh environments such as high temperature, low temperature, high humidity, and high dust. In addition, due to its excellent insulation effect, the slip ring device of this application can effectively resist the influence of external factors such as electromagnetic interference and mechanical vibration, ensuring the stability and reliability of data transmission.
[0059] Furthermore, the slip ring device of this application, based on the technology of direct contact between the contact carbon brush and the axial slip ring, reduces the use of cable wires, avoids wire tangling or breakage, and reduces the resulting failures and maintenance costs, thus extending the service life of the equipment.
[0060] Furthermore, based on its multi-ring structure, the slip ring device of this application allows each conductive ring to correspond to a different transmission channel for devices that need to transmit multiple signals or power simultaneously, thus meeting the transmission requirements of complex devices.
[0061] Furthermore, the slip ring device of this application has a small eccentricity and wobble of the slip ring body, a small frictional torque, and the materials selected for the slip ring device have good wear resistance, which improves the overall performance of the slip ring device.
