Description

Technical Field

[0001] This utility model relates to the field of electronic technology, specifically to an easy-to-maintain star topology network SVG device. Background Technology

[0002] Easy-maintain star topology is a power network connection form based on the optimized design of star topology. Its core feature is that multiple power devices (such as inverters and controllers) are connected in a star configuration with "central node - branch nodes". Power electronic converters generate or absorb reactive power, adjust the power factor of the power grid in real time, suppress voltage fluctuations and harmonics, and ensure the stable operation of the power grid. It is often combined with various topologies to adapt to different power grid scenarios.

[0003] According to the announcement number CN205017332U, an ECATPON master-slave integrated EtherCAT passive optical network star topology is disclosed, including multiple master-slave integrated devices, physical transmission devices, and a central passive optical splitter. This utility model combines passive optical network technology to construct a dedicated EtherCAT master-slave integrated device to realize the various node devices in the ECATPON network structure. Single-mode fiber wavelength division multiplexing technology is used to complete the physical transmission layer, and a central passive optical splitter is used to construct the central node of the star network. This utility model has a novel design and can significantly improve the problems of transmission interference and being interfered with in the original master-station-centered topology, the lack of redundancy security protection, and the unsuitability for long-distance transmission. This makes real-time industrial Ethernet EtherCAT applicable to extreme and harsh environments such as vehicle-mounted, ship-mounted, and airborne applications.

[0004] However, in existing technologies, the location of a star topology network is fixed after installation, which makes it inconvenient for operators to perform maintenance during actual use. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model proposes an easy-to-maintain star topology network SVG device to solve the problems mentioned in the background technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an easy-to-maintain star-shaped topology SVG device, including a star-shaped topology network. A first slot is provided on the upper surface of the star-shaped topology network. A first fixing block is fixedly connected to the upper surface of the star-shaped topology network. A rotating column is rotatably connected inside the first fixing block. A cover plate is fixedly connected to the outer wall of the rotating column. The outer wall of the cover plate is slidably connected to the inner wall of the first slot. A signal processor is fixedly connected to the inner wall of the star-shaped topology network. A rotating block is fixedly connected to the outer wall of the rotating column. A second fixing block is rotatably connected to the inner wall of the rotating block. A slider is fixedly connected to the outer wall of the second fixing block. One end of a first spring is fixedly connected to the outer wall of the slider. The other end of the first spring is fixedly connected to the inner wall of the star-shaped topology network. The outer wall of the slider is slidably connected to the inner wall of the star-shaped topology network. A flipping component is provided inside the star-shaped topology network.

[0007] Preferably, the flipping assembly includes a transmission rod, the outer wall of which is slidably connected to the interior of the star-shaped topology network, the outer wall of which is fixedly connected to the outer wall of the slider, and a first handle is fixedly connected to the outer wall of the transmission rod.

[0008] Preferably, the outer wall of the star-shaped topology network is fixedly connected to a third fixing block, and the upper surface of the third fixing block is provided with a second slot.

[0009] Preferably, the star-shaped topology has short columns that are slidably connected inside, and the outer walls of the short columns are slidably connected to the inner wall of the second slot.

[0010] Preferably, a second handle is fixedly connected to the outer wall of the short column.

[0011] Preferably, a sliding plate is fixedly connected to the outer wall of the short column, and the outer wall of the sliding plate is slidably connected to the inner wall of the star-shaped topology network.

[0012] Preferably, one end of the second spring is fixedly connected to the upper surface of the skateboard, and the other end of the second spring is fixedly connected to the inner wall of the star-shaped topology network.

[0013] Compared with existing technologies, the advantages of this easy-to-maintain star topology SVG device are:

[0014] 1. In this utility model, the first handle can be pulled to close the circuit. When closing, the first handle is no longer pulled, which causes the first spring to reset and the slider to reset the rotating block, thereby causing the cover plate to reset and close automatically. This improves the convenience of maintenance and allows maintenance personnel to quickly access the interior of the star topology network for maintenance when the signal processor needs maintenance.

[0015] 2. In this utility model, by releasing the second handle, the second spring quickly resets the structure, thereby achieving the effect of installing the star topology network. This is beneficial because when the star topology network needs to be installed, the pulling and resetting operation of the second handle enables the rapid installation of the star topology network, allowing the number of star topology networks to be increased according to actual needs.

Detailed Implementation

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] For the easily maintained star topology SVG device described in this specific implementation, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4An easy-to-maintain star-topology SVG device includes a star-topology network 1. A first slot 5 is provided on the upper surface of the star-topology network 1. A first fixing block 2 is fixedly connected to the upper surface of the star-topology network 1. A rotating column 3 is rotatably connected inside the first fixing block 2. A cover plate 4 is fixedly connected to the outer wall of the rotating column 3. The outer wall of the cover plate 4 is slidably connected to the inner wall of the first slot 5. A signal processor 6 is fixedly connected to the inner wall of the star-topology network 1. A rotating block 7 is fixedly connected to the outer wall of the rotating column 3. A second fixing block 8 is rotatably connected to the inner wall of the rotating block 7. A slider 9 is fixedly connected to the outer wall of the second fixing block 8. One end of a first spring 12 is fixedly connected to the outer wall of the slider 9. The other end of the first spring 12 is fixedly connected to the inner wall of the star-topology network 1. The outer wall of the slider 9 is slidably connected to the inner wall of the star-topology network 1. A flipping component is provided inside the star-topology network 1.

[0025] Through the above technical solution, the cover plate 4 is used to open or close. When the cover plate 4 is closed, it can shield the internal components and prevent dust and impurities from entering. When the cover plate 4 is open, it is convenient for maintenance and repair. The first fixing block 2 can limit the rotation of the rotating column 3, ensuring that the rotating column 3 always moves along the circumference during rotation. The rotating block 7 is used to convert the horizontal linear motion of the second fixing block 8 into the rotational motion of the rotating column 3. The slider 9 is used to connect and transmit the second fixing block 8 and the transmission rod 10. One end of the first spring 12 is fixedly connected to the outer wall of the slider 9, and the other end of the first spring 12 is fixedly connected to the inner wall of the star-shaped topology network 1 to limit the elastic range of the first spring 12. After maintenance is completed, it can be quickly reset.

[0026] Please see Figure 2 and Figure 5 The flipping assembly includes a transmission rod 10, the outer wall of which is slidably connected to the inside of the star-shaped topology network 1, the outer wall of which is fixedly connected to the outer wall of the slider 9, and a first handle 11 is fixedly connected to the outer wall of the transmission rod 10.

[0027] Through the above technical solution, the star-shaped topology network 1 can limit the transmission rod 10, ensuring that the transmission rod 10 always moves along a horizontal straight line during the movement. The transmission rod 10 is used to connect and transmit power to the first handle 11 and the slider 9.

[0028] Please see Figure 3 A third fixing block 13 is fixedly connected to the outer wall of the star-shaped topology network 1, and a second slot 14 is provided on the upper surface of the third fixing block 13.

[0029] Through the above technical solution, the second slot 14 opened on the upper surface of the third fixing block 13 can limit the short column 15, ensuring that the short column 15 moves vertically during the movement.

[0030] Please see Figure 5 The star-shaped topology network 1 has short columns 15 slidingly connected inside, and the outer wall of the short columns 15 is slidably connected to the inner wall of the second slot 14.

[0031] Through the above technical solution, the short column 15 facilitates the installation and disassembly of the star topology network 1. When the star topology network 1 needs to be installed or disassembled, it can be quickly installed or disassembled by moving the short column 15.

[0032] Please see Figure 5 A second handle 16 is fixedly connected to the outer wall of the short column 15.

[0033] Through the above technical solution, the second handle 16 makes it easier for the operator to pull the short column 15.

[0034] Please see Figure 5 The outer wall of the short column 15 is fixedly connected to the sliding plate 17, and the outer wall of the sliding plate 17 is slidably connected to the inner wall of the star-shaped topology network 1.

[0035] Through the above technical solution, the sliding plate 17 is used to limit the movement of the short column 15, ensuring that the short column 15 will not slide to the inner wall of the star topology network 1.

[0036] Please see Figure 5 One end of the second spring 18 is fixedly connected to the upper surface of the slide plate 17, and the other end of the second spring 18 is fixedly connected to the inner wall of the star-shaped topology network 1.

[0037] Through the above technical solution, one end of the second spring 18 is fixedly connected to the upper surface of the slide plate 17, and the other end of the second spring 18 is fixedly connected to the inner wall of the star-shaped topology network 1 to limit the elastic range of the second spring 18. After installation, the second spring 18 can quickly reset.

[0038] Its working principle is as follows: When the signal processor 6 needs maintenance, the first handle 11 is pulled outward. The movement of the first handle 11 drives the transmission rod 10 to move, causing the transmission rod 10 to slide inside the star-shaped topology network 1 during the movement. This causes the transmission rod 10 to drive the slider 9 to move, causing the slider 9 to slide on the inner wall of the star-shaped topology network 1. During this process, the movement of the slider 9 drives the second fixed block 8 to move, causing the second fixed block 8 to drive the rotating block 7 to rotate. This causes the rotating block 7 to drive the rotating column 3 to rotate, causing the rotating column 3 to rotate inside the first fixed block 2. During this process, the rotation of the rotating column 3 drives the cover plate 4 to rotate. To open, the first handle 11 is pulled. To close, the first handle 11 is no longer pulled, causing the first spring 12 to reset, which in turn causes the rotating block 7 to reset via the slider 9. This causes the cover plate 4 to reset and close automatically, improving the convenience of maintenance. This allows maintenance personnel to quickly access the interior of the star-shaped topology network 1 for maintenance when the signal processor 6 needs maintenance.

[0039] When the star-shaped topology mesh 1 needs to be installed, pull the second handle 16 upwards. During this movement, the second handle 16 moves the short column 15, causing it to slide against the inner wall of the second slot 14. Simultaneously, the short column 15 slides against the inner wall of the star-shaped topology mesh 1. During this process, the movement of the short column 15 moves the sliding plate 17, causing it to slide against the inner wall of the star-shaped topology mesh 1. At this point, the star-shaped topology mesh 1 can be installed. After installation, release the second handle 16, and the second spring 18 will quickly reset the mesh, thus achieving the desired installation effect. This allows for quick installation of the star-shaped topology mesh 1 by pulling and resetting the second handle 16 when needed, enabling the number of star-shaped topology meshes to be increased according to actual requirements.

[0040] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
