Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a slip ring protection device. Background Technology

[0002] In many fields of mechanical equipment involving rotating conductive components, such as wind turbine generators, medical imaging equipment (such as CT scanners), and industrial robots, slip rings play a crucial role as a key rotating conductive component. Slip rings enable the transmission of electricity and signals between rotating and stationary components, ensuring the normal operation of various functions of the equipment during rotation.

[0003] Existing slip rings are typically installed in mechanical equipment that requires rotary connections to transmit power, signals, or data. However, during use, because slip rings are usually in a relatively open or semi-open working environment, dust, particulate matter, and other impurities in the surrounding air can easily adhere to the slip ring surface and enter the slip ring's interior. This not only easily interferes with the slip ring's normal conductivity, leading to problems such as unstable signal transmission and increased power loss, but also accelerates the oxidation and corrosion process of the slip ring, shortening its service life.

[0004] Therefore, it is necessary to design a slip ring protection device that can seal and protect the slip ring from dust while also protecting the connection between the sealing cover and the sealing sleeve to prevent dust and other impurities from entering, prevent the slip ring from oxidizing or corroding, extend its service life, and improve its operational stability. Utility Model Content

[0005] To overcome the shortcomings of slip rings, which are typically in a relatively open or semi-open working environment, where dust, particulate matter, and other impurities in the surrounding air easily adhere to the slip ring surface and enter the slip ring interior, leading to unstable signal transmission, accelerating the oxidation and corrosion process of the slip ring, and shortening its service life, this utility model provides a slip ring protection device that can seal and protect the slip ring from dust while also protecting the connection between the sealing cover and the sealing sleeve, preventing dust and other impurities from entering, preventing oxidation or corrosion of the slip ring, extending its service life, and improving its operational stability.

[0006] Technical solution: A slip ring protection device includes a fixed block, a sealing sleeve, a rotating shaft, a slip ring, a cable, a heat insulation component, and a protective component. The sealing sleeve is connected to the middle of the fixed block, and the slip ring is snapped into the middle of the sealing sleeve. The upper and lower parts of the slip ring are connected to the rotating shaft, with the lower rotating shaft passing through the sealing sleeve. A cable is connected to the lower right side of the slip ring. The sealing sleeve is provided with a heat insulation component for cooling and sealing the slip ring, and the heat insulation component is provided with a protective component for protecting the connection.

[0007] As an improvement to the above solution, mounting holes are provided on both the left and right sides of the fixing block.

[0008] As an improvement to the above solution, the thermal insulation component includes a rubber sleeve, a thermal insulation cover, inlet and outlet ports, and a sealing cover. The rubber sleeve is connected to the lower right side of the sealing sleeve, through which the cable passes. The thermal insulation cover is connected to the outer side of the sealing sleeve. Inlet and outlet ports are connected to the lower left and right sides of the thermal insulation cover. The sealing cover is connected to the upper part of the sealing sleeve by a thread, and the upper rotating shaft passes through the sealing cover.

[0009] As an improvement to the above solution, the protective component includes a shield, guide plate, screw, screw sleeve and sliding frame. The upper front and rear sides of the heat insulation cover are connected to guide plates, and shields are slidably connected to the guide plates. The shields are snapped into the heat insulation cover. The right side of the heat insulation cover is rotatably connected to the screw, and the screw sleeve is connected to the screw by thread. The screw sleeve is slidably connected to the heat insulation cover. The front and rear sides of the screw sleeve are connected to two left and right sliding frames, and the sliding frames are slidably connected to the shield on the same side.

[0010] As an improvement to the above scheme, the guide plates are all T-shaped.

[0011] As an improvement to the above solution, a knob is also included, with a knob connected to the lower side of the screw.

[0012] The present invention has the following advantages: 1. The present invention achieves sealing protection by assembling a slip ring, a sealing sleeve, a sealing cover and a rotating shaft. The movement of the screw sleeve drives the sliding frame to move, so that the shield closes to protect the connection between the sealing cover and the sealing sleeve. Thus, the slip ring can be sealed and protected from dust, while the connection between the sealing cover and the sealing sleeve is protected, preventing dust and other impurities from entering, preventing the slip ring from oxidizing or corroding, extending its service life and improving its stability in use.

[0013] 2. This utility model connects to external cold water through the inlet and outlet, allowing water to enter the insulation cover and then be used on the slip ring. The rotation of the equipment drives the rotating shaft to rotate, causing the rotor on the slip ring to rotate. During use, the slip ring is cooled by cold water, which can prevent material aging, ensure the performance of the slip ring, further extend its service life, and improve transmission stability.

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] A slip ring protection device, such as Figures 1-4 As shown, it includes a fixing block 1, a sealing sleeve 2, a rotating shaft 3, a slip ring 4, a cable 5, a heat insulation component, and a protective component. The fixing block 1 has mounting holes on both the left and right sides for easy installation and use. The sealing sleeve 2 is connected to the middle of the fixing block 1, and the slip ring 4 is snapped into the middle of the sealing sleeve 2. The rotating shaft 3 is connected to both the upper and lower parts of the slip ring 4. The lower rotating shaft 3 passes through the sealing sleeve 2. The cable 5 is connected to the lower right side of the slip ring 4. The sealing sleeve 2 is equipped with a heat insulation component for cooling and sealing the slip ring 4. The heat insulation component is equipped with a protective component for protecting the connection.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the thermal insulation assembly includes a rubber sleeve 6, a thermal insulation cover 7, an inlet / outlet 71, and a sealing cover 8. The rubber sleeve 6 is connected to the lower right side of the sealing sleeve 2, and the cable 5 passes through the rubber sleeve 6. The thermal insulation cover 7 is connected to the outer side of the sealing sleeve 2. The inlet / outlet 71 is connected to the lower left and right sides of the thermal insulation cover 7. The sealing cover 8 is connected to the upper part of the sealing sleeve 2 by a thread, and the upper rotating shaft 3 passes through the sealing cover 8.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the protective assembly includes a shield 9, a guide plate 91, a screw 10, a screw sleeve 12, and a sliding frame 13. The upper front and rear sides of the heat insulation cover 7 are connected to the guide plate 91. The guide plate 91 is T-shaped to facilitate guidance. The shield 9 is slidably connected to the guide plate 91. The shield 9 is snapped into the heat insulation cover 7. The right side of the heat insulation cover 7 is rotatably connected to the screw 10. The screw 10 is threadedly connected to the screw sleeve 12. The screw sleeve 12 is slidably connected to the heat insulation cover 7. The front and rear sides of the screw sleeve 12 are connected to two left and right sliding frames 13. The sliding frames 13 are slidably connected to the shield 9 on the same side. It also includes a knob 11. The screw 10 is connected to the lower side of the knob 11 for easy hand gripping and turning of the screw 10.

[0023] When the slip ring 4 needs to be used and protected, this device can be used. The fixing block 1 contacts the equipment where the slip ring 4 needs to be used, and then the fixing piece passes through the mounting hole for fixation. Next, the slip ring 4 contacts the sealing sleeve 2, and then the slip ring 4 is pushed to move for installation, so that the lower rotating shaft 3 passes through the sealing sleeve 2. Then, the sealing cover 8 passes through the upper rotating shaft 3 and contacts the sealing sleeve 2, and then the sealing cover 8 is rotated to move for installation, achieving a seal. Simultaneously, the rubber sleeve 6 seals the connection of the cable 5. Next, the screw 10 is rotated by the knob 11, causing the screw sleeve 12 to move under the action of the thread, driving the sliding frame 13 to move, causing the shield 9 to move along the guide plate 91 and close, engaging with the heat insulation cover 7, thereby protecting the connection between the sealing cover 8 and the sealing sleeve 2, achieving the connection between the equipment and maintaining their integrity. The current or signal transmission between the rotating and fixed parts is achieved through the cable 5. The guide plates 91 are all T-shaped to facilitate guidance, thereby sealing and protecting the slip ring 4 from dust while also protecting the connection between the sealing cover 8 and the sealing sleeve 2. This prevents dust and other impurities from entering, prevents oxidation or corrosion of the slip ring 4, extends its service life, and improves its operational stability. Then, cold water is connected to the inlet and outlet 71 to allow water to enter the heat insulation cover 7. Subsequently, the slip ring 4 is used. The rotation of the equipment drives the rotating shaft 3 to rotate, causing the rotor on the slip ring 4 to rotate. During use, the slip ring 4 is cooled by cold water, which can cool the slip ring 4 during use, prevent material aging, ensure the performance of the slip ring 4, further extend its service life, and improve transmission stability.
