Description

Technical Field

[0001] This utility model relates to the field of optical cable line operation and maintenance, and in particular to a splice box for locating optical cables in ducts. Background Technology

[0002] Optical fiber splice boxes are mainly used as repeater or branch points in optical fiber lines, playing a crucial role in optical fiber communication networks. They connect optical fibers at the end or connection point to form a seamless optical fiber connection, ensuring stable and reliable transmission of optical fiber signals.

[0003] When locating and positioning optical cable splice boxes, the intelligent operation and maintenance instrument for optical transmission lines is used. Based on distributed optical fiber vibration sensing technology and optical time domain reflection technology, it highly integrates the high-sensitivity optical cable positioning and detection function with OTDR optical fiber link status analysis technology to achieve a combination of functions. It can locate the position of optical cable splice boxes. However, some optical splice boxes are backfilled by directly pressing the splice box with sandbags. During the backfilling process, the sandbags may be compacted, which will put a certain pressure on the splice box, resulting in a weakening of the vibration signal intensity and a reduction in the transmission speed.

[0004] Existing fusion splice boxes may focus too much on the splicing and protection of optical cables, while neglecting the optimization of the vibration signal transmission path and receiving point, resulting in poor vibration signal reception and low transmission efficiency.

[0029] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] Example 1

[0032] Reference Figures 1-5 A splice box for locating optical cables in pipelines includes: an outer shell 100, which includes an upper shell and a lower shell, the upper shell being disposed above the lower shell; an inner shell 200 disposed inside the outer shell 100, the inner shell 200 having a fiber splicing tray inside; and several first conductive plates 300 installed on the outer wall of the outer shell 100, the several first conductive plates 300 being arranged in a linear array, the first conductive plates 300 being connected to the inner shell 200.

[0033] In this embodiment, the design of the inner and outer shells 100 physically forms an isolation layer, effectively reducing the direct impact of external environmental factors (such as sandbag pressure, soil compression, etc.) on the vibration sensor inside the splice box. This isolation helps maintain the sensitivity and accuracy of the vibration sensor, ensuring that the vibration signal can be transmitted normally. The inner shell 200 provides a stable foundation for optical cable splicing, while the outer shell 100 further enhances the structural stability of the entire splice box. This stability is crucial for resisting external pressure and vibration, helping to reduce the attenuation and distortion of the vibration signal during transmission, while providing sufficient strength and protection to protect the internal optical cable from external environmental influences. During excavation, if the excavation tools damage the splice box, the outer shell 100 can serve as the outermost layer of the splice box, undertaking the main task of resisting external environmental damage. The outer shell 100 is typically made of robust and durable materials, such as high-strength plastics or metal alloys, which have excellent impact resistance, corrosion resistance, and aging resistance. Therefore, the outer casing 100 can ensure that the splice box can operate stably for a long time in harsh environments and extend its service life, while the inner casing 200 provides double protection to prevent damage to the internal optical cable when the splice box is excavated.

[0034] The first conductive plate 300 effectively transmits vibration signals from the outer shell 100 to the inner shell 200. Because they are distributed in a linear array on the outer wall of the outer shell 100 and connected to the inner shell 200, it ensures that the vibration signals can be transmitted efficiently along a specific path. The linear array distribution not only improves the uniformity of signal transmission, that is, ensures that each conductive plate can receive and transmit vibration signals, but also enhances the accuracy of signal transmission and reduces signal attenuation and distortion during transmission. In the maintenance and management of duct optical cables, it is crucial to quickly and accurately locate the position of the optical cable splice box. The first conductive plate 300, through its vibration sensing function, can respond to vibration signals from the outside. These vibration signals are transmitted to the inner shell 200 and then captured and processed by the sensors inside the splice box. By analyzing these vibration signals, the approximate location of the optical cable splice box can be quickly determined, thereby improving the efficiency of locating duct optical cables.

[0035] The outer casing 100 further includes: two connecting plates 400, which are respectively installed on the upper casing and the lower casing, and are sealed together by a sealing element; and a sealing plug 401 installed on the connecting plates 400.

[0036] The aforementioned connecting plate 400 is sealed and connected by a sealing element, ensuring the integrity of the outer casing 100 and its waterproof and dustproof performance. The sealed connection improves the durability and environmental adaptability of the splice box, ensuring the long-term stability of optical cable splicing. The sealing plug 401 enhances the sealing performance of the splice box, preventing external moisture, dust and other impurities from entering and affecting the quality of optical cable splicing and the life of the equipment.

[0037] The connecting plate 400 includes: a second conductive plate 402, which is installed on the sealing plug 401, and the outer shell 100 is connected to the second conductive plate 402; a protrusion, which is installed on the side of the connecting plate 400, and the protrusion is provided with bolts, and the two connecting plates 400 are connected by bolts; the second conductive plate 402 further improves the transmission efficiency of vibration signals, making the process of finding the optical cable in the pipeline more accurate and faster.

[0038] The first conductive plate 300 includes a vibration plate 301, which is installed on the first conductive plate 300. The vibration plate 301 is disposed through the outer shell 100, and the first conductive plate 300 is connected to the inner shell 200 through the vibration plate 301.

[0039] The aforementioned vibrating plate 301 serves as a transmission medium for vibration signals, improving the transmission efficiency and accuracy of vibration signals and facilitating rapid positioning of the optical cable splice box. The first transmission plate 300 and the vibrating plate 301 are made of materials with high vibration transmission performance, such as stainless steel or special alloys, to ensure that vibration signals can be transmitted efficiently.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is as follows:

[0042] Reference Figure 6 and Figure 7 The vibration conductor 302 is disposed through both the first conductive plate 300 and the vibration plate 301, and one end of the vibration conductor 302 is connected to the inner shell 200; a through hole is formed on the first conductive plate 300, and the vibration conductor 302 is installed in the through hole; the vibration conductor 302 adopts a sheet structure or a rod structure.

[0043] In this embodiment, by having the vibration conductor 302 simultaneously penetrate both the first conduction plate 300 and the vibration plate 301 and connect it to the inner housing 200, it is ensured that the vibration signal is not excessively attenuated or interfered with during transmission. This guarantees the accuracy and reliability of the vibration signal, allowing the welded box to accurately respond to external vibration stimuli. The vibration conductor 302 can be either sheet-like or rod-like, allowing it to be selected according to actual needs to adapt to different application scenarios and installation conditions. For example, in scenarios requiring high sensitivity, a sheet-like vibration conductor 302 can be selected to better capture and transmit weak vibration signals; while in scenarios requiring greater pressure or impact, a rod-like vibration conductor 302 can be selected to improve its durability and stability. Placing the vibration conductor 302 inside the first conduction plate 300 and the vibration plate 301 can further optimize the transmission efficiency of the vibration signal. Since the first conduction plate 300 and the vibration plate 301 themselves have vibration transmission functions, they can work together with the vibration conductor 302 to form a highly efficient vibration signal transmission system. It can not only increase the transmission speed of vibration signals, but also reduce signal loss and interference during transmission, thereby improving the vibration sensing performance of the entire welding box.

[0044] During use, the upper and lower shells are sealed together using a sealing element via a connecting plate 400 to ensure the integrity and waterproof / dustproof performance of the outer shell 100. The inner shell 200 is placed inside the outer shell 100, ensuring its stability and correct positioning. A fiber splicing tray is installed inside the inner shell 200 for splicing and securing the optical cable. Several first conductive plates 300 are linearly arrayed on the outer wall of the outer shell 100. A vibrating plate 301 is installed on each first conductive plate 300, ensuring that the vibrating plate 301 penetrates the outer shell 100 and connects to the inner shell 200. A vibration conductor 302 is installed in the through-holes on the first conductive plates 300, ensuring that the vibration conductor 302 simultaneously penetrates both the first conductive plate 300 and the vibrating plate 301 and connects to the inner shell 200. A sheet-like or rod-shaped vibration conductor can be selected according to actual needs. 302. The splice box is installed at the designated location on the duct optical cable to ensure accurate response to external vibration stimuli. When external excavation tools or other vibration sources vibrate the splice box, the vibration signal is first received by the vibrating plate 301 on the first transmission plate 300. The vibration signal is then transmitted through the vibrating plate 301 to the first transmission plate 300, and then efficiently transmitted to the inner shell 200 along the linear array path of the first transmission plate 300. Simultaneously, the vibration signal is further transmitted to the inner shell 200 through the vibration transmission component 302, ensuring the accuracy and reliability of the vibration signal. Sensors inside the splice box capture and process the vibration signals from the inner shell 200. By analyzing these vibration signals, the approximate location of the optical cable splice box can be quickly determined. Based on the analysis results of the vibration signals, workers can quickly and accurately locate the position of the optical cable splice box. This helps improve work efficiency in the maintenance and management of duct optical cables.

[0045] In summary, compared with existing technologies, it has the following beneficial effects:

[0046] By setting the first conductive plate 300 and the vibration plate 301 on the splice box, it is ensured that the vibration signal will not be excessively attenuated or interfered with during transmission, the transmission path of the vibration signal is optimized, the accuracy and reliability of the signal are improved, and the splice box can more accurately locate the position of the optical cable splice box, which helps to improve work efficiency in the maintenance and management of pipeline optical cables.

[0047] The uniformity of signal transmission is improved, and the sensitivity of signal reception is enhanced. The vibration plate 301, as the transmission medium of vibration signal, improves the transmission efficiency and accuracy of signal, enabling the welding box to respond to external vibration stimuli more quickly.

[0048] The design of the inner and outer shells 100 physically forms an isolation layer, which effectively reduces the direct impact of the external environment on the vibration sensor inside the welding box, enhances the structural stability and durability of the welding box, and enables it to operate stably for a long time.
