Description

Technical Field

[0001] This application relates to the field of optical fiber transmitter technology, and more specifically, to a device for parallel acquisition and optical fiber transmission of multi-channel analog signals. Background Technology

[0002] Multi-channel analog signal parallel acquisition devices are responsible for efficiently acquiring multiple analog signals. However, the acquired signals need to be transmitted and further processed. Fiber optic transmission devices, with their advantages of high bandwidth and low attenuation, can transmit the data acquired from the parallel acquisition of multi-channel analog signals over long distances with high quality. For example, in large-scale monitoring systems, multi-channel analog signal parallel acquisition devices collect analog signals at various monitoring points, and then transmit these data quickly and accurately to the data processing center through fiber optic transmission devices to achieve centralized data analysis and processing.

[0003] Existing fiber optic transmission devices primarily use clips and screws to secure two sets of housings to enclose internal components. As a result, when a fault occurs inside the fiber optic transmission device, tools are needed to remove the screws. Furthermore, since the upper and lower housings are connected by clips on the inside, it is difficult to pry them open during disassembly, which can easily cause the housings to crack, thus increasing the difficulty of disassembling the fiber optic transmission device.

[0004] To address the aforementioned issues, this application provides a device for parallel acquisition and fiber optic transmission of multi-channel analog signals. Utility Model Content

[0005] The multi-channel analog signal parallel acquisition and fiber optic transmission device provided in this application adopts the following technical solution: A multi-channel analog signal parallel acquisition and fiber optic transmission device includes a fiber optic device body, an auxiliary mechanism on the outside of the fiber optic device body, and the auxiliary mechanism extending into the interior of the fiber optic device body. The auxiliary mechanism includes a housing located on top of the fiber optic device body. Two rotating plates are provided on both the front and rear sides of the fiber optic device body. The four rotating plates are symmetrically arranged in pairs around the centerline of the fiber optic device body. Each of the four rotating plates is movably connected to the fiber optic device body via hinges. A square slot is formed on the inner side of each of the four rotating plates, and a square block is embedded within each of the four square slots. Two bidirectional screws are threaded into each of the four square blocks. Two limiting slots are formed on both the front and rear sides of the fiber optic device body, and limiting blocks are embedded within each of the four limiting slots. The four limiting blocks are fixedly connected to the four square blocks respectively. A set of SPI interfaces is installed inside the fiber optic device body, and a transmission structure is provided on the outer side of each of the four square blocks.

[0006] Furthermore, two connecting frames are fixedly connected to the bottom of the optical fiber device body. The two connecting frames are symmetrically arranged about the center line of the optical fiber device body, and two positioning seats are movably sleeved on the outer side of each of the two connecting frames.

[0007] The above technical solution, through the cooperation of two connecting frames and two positioning seats, can improve the flexibility of the device during use.

[0008] Furthermore, the transmission structure includes two gears, which are respectively fixedly sleeved on the outside of two bidirectional screws.

[0009] Furthermore, both gears have meshing toothed plates on their inner sides, and both toothed plates are fixedly connected to the outer casing by a cross plate.

[0010] The above technical solution allows two bidirectional screws to rotate by meshing two gears.

[0011] Furthermore, each of the two horizontal plates has two pull rods movably embedded inside, and the bottom outer sides of the four pull rods are fixedly sleeved with fixing plates, and the two fixing plates are respectively fixedly connected to the two toothed plates.

[0012] Furthermore, two springs are fixedly connected between each of the two horizontal plates and the two fixed plates, and the four springs are respectively sleeved on the outside of the four pull rods. A movable plate is fixedly connected to the top of the four pull rods.

[0013] The above technical solution, by setting up a movable plate, facilitates the subsequent adjustment of the height of the two toothed plates.

[0014] Furthermore, four support blocks are movably sleeved on the outer side of the two bidirectional screws, and all four support blocks are fixedly connected to the optical fiber device body.

[0015] The above technical solution, by setting four support blocks, can support the two bidirectional screws.

[0016] In summary, this application includes the following beneficial technical effects: In use, the two bidirectional screws can be rotated by the transmission components. Since the threads at both ends of the two bidirectional screws turn in opposite directions, and the four limit blocks are matched with the four limit slots respectively, the four square blocks can move towards each other in pairs. When the four square blocks are separated from the four rotating plates respectively, the restriction on the outer shell can be released, and the outer shell can be disassembled, thereby improving the operating efficiency and preventing the outer shell from cracking easily.

[0022] Example: This application discloses a multi-channel analog signal parallel acquisition and fiber optic transmission device. Please refer to [link to relevant documentation]. Figures 1 to 3 The optical fiber device body 1 includes an auxiliary mechanism on the outside of the optical fiber device body 1, which extends into the interior of the optical fiber device body 1. The auxiliary mechanism includes a housing 2, which is located on top of the fiber optic device body 1. Two rotating plates 3 are provided on both the front and rear sides of the fiber optic device body 1. The four rotating plates 3 are symmetrically arranged in pairs with the center line of the fiber optic device body 1 as the axis. The four rotating plates 3 are movably connected to the fiber optic device body 1 through hinges 4. Square slots are opened on the inner side of the four rotating plates 3. Square blocks 5 are embedded in the four square slots. Two bidirectional screws 6 are threaded into the four square blocks 5. Two limiting slots are opened on both the front and rear sides of the fiber optic device body 1. Limiting blocks 7 are embedded in the four limiting slots. The four limiting blocks 7 are fixedly connected to the four square blocks 5 respectively. A set of SPI interfaces 8 is installed inside the fiber optic device body 1. Two connecting frames 9 are fixedly connected to the bottom of the fiber optic device body 1. The two connecting frames 9 are symmetrically arranged with the center line of the fiber optic device body 1 as the axis. Two positioning seats 10 are movably sleeved on the outer side of the two connecting frames 9. Please see Figure 1 and Figure 3 The four square blocks 5 are provided with a transmission structure on the outside. The transmission structure includes two gears 11. The two gears 11 are respectively fixedly sleeved on the outside of two bidirectional screws 6. The inner sides of the two gears 11 are meshed with toothed plates 12. The two toothed plates 12 are fixedly connected to the outer shell 2 with cross plates 13. Please see Figure 1 and Figure 3 Two tie rods 14 are movably embedded inside each of the two horizontal plates 13. Fixed plates 15 are fixedly sleeved on the outer side of the bottom of the four tie rods 14. The two fixed plates 15 are fixedly connected to the two toothed plates 12 respectively. Two springs 16 are fixedly connected between the two horizontal plates 13 and the two fixed plates 15. The four springs 16 are respectively sleeved on the outer side of the four tie rods 14. A movable plate 17 is fixedly connected to the top of the four tie rods 14. Please see Figure 1 Four support blocks are movably sleeved on the outer side of the two bidirectional screws 6, and all four support blocks are fixedly connected to the optical fiber device body 1.

[0023] The implementation principle of this embodiment is as follows: When in use, the movable plate 17 can be pulled to move the movable plate 17 upward. At this time, the movable plate 17 will drive the four pull rods 14 and the two fixed plates 15 to move upward synchronously. At this time, the four springs 16 will be stressed, deformed, and in a compressed state. Since the two fixed plates 15 are fixedly connected to the two toothed plates 12 respectively, the two toothed plates 12 can be moved upward. Since the two toothed plates 12 are meshed with the two gears 11 respectively, the two gears 11 can be rotated. Subsequently, the two bidirectional screws 6 will rotate. Since the threads at both ends of the two bidirectional screws 6 turn in opposite directions, and the four limiting blocks 7 are matched with the four limiting slots respectively, the four square blocks 5 can be moved towards each other in pairs. When the four square blocks 5 are disengaged from the four rotating plates 3 respectively, the restriction on the outer shell 2 can be released, and the outer shell 2 can be disassembled, thereby improving the operating efficiency and avoiding the phenomenon that the outer shell 2 is prone to cracking. Because it has a set of SPI interfaces 8, it can realize the parallel acquisition of multi-channel analog signals, and each channel is isolated, which enhances the anti-interference capability of the whole system.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
