Description

Technical Field

[0001] This utility model relates to the technical field of optical cable protection equipment, and more specifically, to a sealing device for an optical cable downpipe. Background Technology

[0002] Optical cable downpipes are a common method for laying optical cables inside buildings. The optical cable is usually encased in a downpipe, which is connected to the building's underground pipelines. When the optical cable inside the building gets damp, water can seep into the underground pipelines through the downpipe, causing short circuits or damage to the lines within the pipelines, threatening the safety of the optical cable and affecting the stability of communication. Therefore, it is necessary to waterproof the optical cable downpipes to ensure that there is no water accumulation inside them.

[0003] Existing waterproofing technologies for fiber optic cable downpipes involve sealing them with waterproof sealant. However, this sealant is prone to hardening and cracking or detachment after prolonged use, leading to water accumulation inside the downpipe, which threatens the safety of the fiber optic cable and affects communication stability. Utility Model Content

[0004] The main purpose of this invention is to provide a sealing device for optical cable downpipes to solve the problem of poor stability of waterproof sealant sealing in the prior art.

[0005] To achieve the above objectives, this utility model provides a sealing device for an optical cable downpipe, wherein a portion of the optical cable passes through the downpipe, and the sealing device for the optical cable downpipe includes:

[0006] First half-cylinder column;

[0007] The second half-cylinder, the first half-cylinder and the second half-cylinder are fastened together to form a sealing sleeve. Part of the sealing sleeve is fitted onto the downlead tube, and the other part of the sealing sleeve is fitted onto the optical cable.

[0008] Fasteners are used to connect the first and second half-cylinders.

[0009] Furthermore, the sealing sleeve includes a first sleeve section, a connecting section, and a second sleeve section connected in sequence. The inner diameter of the first sleeve section is smaller than the inner diameter of the second sleeve section. The first sleeve section is fitted on the outside of the optical cable, and the second sleeve section is fitted on the outside of the downlead tube.

[0010] Furthermore, the connecting section abuts against the top end face of the downpipe.

[0011] Furthermore, there are at least two fasteners, with at least one fastener fitted on the outside of the first sleeve section and at least another fastener fitted on the outside of the second sleeve section.

[0012] Furthermore, the fastener is a clamp.

[0013] Furthermore, the materials of the first and second semi-cylinders include rubber and silicone.

[0014] Furthermore, the sealing device for the optical cable downpipe also includes: a water accumulation detection component, a portion of which is located inside the downpipe and is used to detect water accumulation inside the downpipe; a water accumulation removal component, a portion of which is located inside the downpipe and is used to remove water accumulation inside the downpipe, wherein the water accumulation detection component and the water accumulation removal component are signal connected; and a power supply component, located above the sealing sleeve, which is connected to the water accumulation detection component and the water accumulation removal component, and provides power to the water accumulation detection component and the water accumulation removal component.

[0015] Furthermore, the water accumulation removal component includes: a drain pipe located inside the downpipe, with the inlet end of the drain pipe located at the bottom of the downpipe and the outlet end of the drain pipe extending through the sealing sleeve; and a drain pump located at the inlet end of the drain pipe, connected to a power supply component and a signal connection to the water accumulation detection component.

[0016] Furthermore, the water accumulation detection component includes: a water accumulation detection sensor, a portion of which is located inside the drain pipe and is connected to the power supply component; and a signal transmitting unit, which is electrically connected to the power supply component, signal-connected to the water accumulation detection sensor, and signal-connected to the water accumulation removal component.

[0017] Furthermore, the water accumulation detection sensor includes a water immersion sensor, which is wound around an optical cable. A portion of the water immersion sensor is located between the sealing sleeve and the optical cable, and one end of the water immersion sensor extends from the top of the sealing sleeve and is connected to the power supply component.

[0018] Using the technical solution of this utility model, a portion of the optical cable is inserted into the downlead tube. The sealing device of the optical cable downlead tube includes a first half-cylinder, a second half-cylinder, and fasteners. The first half-cylinder and the second half-cylinder are fastened together to form a sealing sleeve. A portion of the sealing sleeve is fitted onto the downlead tube, and the other portion of the sealing sleeve is fitted onto the optical cable. The first half-cylinder and the second half-cylinder are connected by fasteners.

[0019] The sealing sleeve is formed by the interlocking of a first and second semi-cylindrical column, allowing it to tightly conform to the outer surfaces of the optical cable and downconductor, creating a seamless protective layer. This avoids the gaps and irregular shapes inherent in traditional materials like fireproof putty during the sealing process, significantly reducing the penetration paths of water and moisture. The first and second semi-cylindrical columns are connected by fasteners to ensure the sealing sleeve is stably fixed to the optical cable and downconductor during installation, preventing loosening and detachment due to wind, vibration, or temperature changes, thus enhancing the reliability of the sealing. This design ensures a tight connection between the optical cable and downconductor, effectively preventing the intrusion of external factors such as rainwater and moisture, and improving the protective performance of the optical cable. It has a wide range of applications, especially suitable for outdoor communication base stations, power facilities, monitoring systems, and other situations requiring optical cable downconductors.

[0027] In order to solve the problem of poor stability of waterproof sealant in the existing technology, the main purpose of this utility model is to provide a sealing device for optical cable downpipe.

[0028] like Figure 1 As shown, a portion of the optical cable 10 is inserted into the down-lead tube 90. The sealing device of the optical cable down-lead tube includes a first half-cylinder 20, a second half-cylinder 30, and a fastener 40. The first half-cylinder 20 and the second half-cylinder 30 are fastened together to form a sealing sleeve. A portion of the sealing sleeve is fitted onto the down-lead tube 90, and the other portion of the sealing sleeve is fitted onto the optical cable 10. The first half-cylinder 20 and the second half-cylinder 30 are connected by the fastener 40.

[0029] The sealing sleeve is formed by the interlocking of the first semi-cylindrical column 20 and the second semi-cylindrical column 30, allowing it to tightly fit the outer surfaces of the optical cable 10 and the downconductor 90, thus forming a seamless protective layer. This avoids the gaps and irregular shapes inherent in traditional materials such as fireproof putty during the sealing process, significantly reducing the penetration paths of water and moisture. The first semi-cylindrical column 20 and the second semi-cylindrical column 30 are connected by fasteners 40 to ensure that the sealing sleeve is stably fixed to the optical cable 10 and the downconductor 90 during installation, preventing loosening and detachment due to wind, vibration, or temperature changes, and enhancing the reliability of the sealing. This design ensures a tight connection between the optical cable and the downconductor 90, effectively preventing the intrusion of external factors such as rainwater and moisture, and improving the protective performance of the optical cable. It has a wide range of applications, especially suitable for outdoor communication base stations, power facilities, monitoring systems, and other occasions requiring optical cable downconductors.

[0030] In some alternative embodiments, please refer to Figure 1 The sealing sleeve comprises a first sleeve section 51, a connecting section 52, and a second sleeve section 53 connected sequentially. The inner diameter of the first sleeve section 51 is smaller than the inner diameter of the second sleeve section 53. The first sleeve section 51 is fitted onto the outside of the optical cable 10, and the second sleeve section 53 is fitted onto the outside of the down-lead tube 90. The first sleeve section 51 is adapted to the outer diameter of the optical cable 10, and the second sleeve section 53 is adapted to the outer diameter of the down-lead tube 90. This segmented structural design takes into account the possible dimensional changes of the optical cable 10 and the down-lead tube 90 at the connection point, matching the dimensions of different parts separately to ensure the sealing of the entire connection point, while simplifying the installation process and improving installation efficiency. In addition, the first half-cylinder 20 and the second half-cylinder 30 are connected as a whole by fasteners 40. This connection method can not only ensure the stability of the sealing sleeve on the optical cable 10 and the down-lead tube 90, but also adapt to the slight size changes between the two. Even under the action of external forces (such as vibration), it can maintain a good sealing state and effectively prevent the intrusion of external factors such as rainwater and moisture.

[0031] It should be noted that the first sleeve section 51 is fitted on the outside of the optical cable 10 and abuts against the outer circumferential surface of the optical cable 10. The second sleeve section 53 is fitted on the outside of the downlead tube 90 and abuts against the outer circumferential surface of the downlead tube 90.

[0032] In some alternative embodiments, please refer to Figure 1 The connecting section 52 abuts against the top end face of the downpipe 90. The design of the connecting section 52 allows the sealing sleeve to fit tightly against the top of the downpipe 90, forming an effective waterproof barrier to prevent moisture from entering from the top of the downpipe 90. It is particularly suitable for rainy areas or environments with high humidity.

[0033] By matching the outer diameter of the first sleeve section 51 with the outer diameter of the optical cable 10, and matching the outer diameter of the second sleeve section 53 with the outer diameter of the downpipe 90, the connecting section 52 can completely wrap around the top of the downpipe 90, forming a continuous and seamless sealing interface. This sealing interface can effectively prevent liquid from seeping through the gap between the downpipe 90 and the optical cable 10, thereby forming an effective waterproof barrier.

[0034] The structural design of the connecting section 52 takes into account the possible size differences and shape changes at the connection between the optical cable 10 and the down-lead tube 90. Through the segmented design, the optical cable 10 and the down-lead tube 90 are matched in size to ensure the sealing and stability of the entire sealing sleeve.

[0035] In summary, the design of the connection section, through material selection, fastener application, structural optimization, and sealing design, enables the sealing device to fit tightly against the top of the downpipe, forming an effective waterproof barrier that protects the optical cable from external moisture, thereby improving the cable's protective performance and the stability of the communication system.

[0036] In some alternative embodiments, please refer to Figure 1 There are at least two fasteners 40, with at least one fastener 40 fitted on the outside of the first sleeve section 51 and at least another fastener 40 fitted on the outside of the second sleeve section 53. Using multiple fasteners 40 can ensure that the sealing device of the optical cable downpipe is firmly fixed on the optical cable 10 and the downpipe 90, avoiding loosening caused by external factors such as wind and vibration, and is suitable for sealing the downpipe 90 in various complex environments.

[0037] Fastener 40 secures the sealing sleeve to the optical cable 10 and the downconductor 90, providing support and fixation. Using multiple fasteners increases the number of fixing points for the sealing sleeve, thereby creating a more uniform fixing force in the circumferential direction of the optical cable 10 and the downconductor 90. This ensures the stability of the sealing sleeve even under strong winds or vibration conditions, preventing damage to the waterproof seal due to loosening.

[0038] The design of the multiple fasteners 40 also takes into account possible variations in the dimensions of the optical cable 10 and the downlead tube 90. The fasteners can be adjusted independently, allowing the sealing sleeve to accommodate minor differences in the diameter of the optical cable 10 or the downlead tube 90 within a certain range, ensuring a tight fit and forming an effective waterproof barrier even when the dimensions are not perfectly matched.

[0039] The use of multiple fasteners 40 in the sealing sleeve design also takes into account the convenience of installation and maintenance. Installing the fasteners 40 is generally simpler than with a single, integrated fastener, allowing for quick adjustment and securing, thus improving on-site construction efficiency. Furthermore, if a portion of the sealing sleeve is damaged or aged, only the corresponding fastener 40 needs to be replaced or adjusted, eliminating the need for complete disassembly and reducing subsequent maintenance costs and complexity.

[0040] In practical applications, the downlead duct 90 may be subjected to various complex environmental influences, such as wind, vibration, and temperature changes. The design of multiple fasteners 40 allows the sealing sleeve to be more securely fixed, maintaining a good seal even under these adverse conditions, effectively preventing moisture intrusion and protecting the optical cable 10 from damage.

[0041] In some alternative embodiments, the fastener 40 is a clamp. The use of clamps not only simplifies the installation process but also ensures a tight fixation of the sealing sleeve, making it suitable for scenarios requiring rapid installation and maintenance, such as emergency repairs or large-scale engineering deployments.

[0042] Furthermore, the clamp is designed as a ring structure, which, when applied to the surface of the optical cable 10 or the downlead tube 90, can evenly distribute the tightening force, ensuring consistent pressure on the contact surface between the sealing sleeve and the optical cable 10 or the downlead tube 90, thereby forming a continuous and uniform sealing layer. This uniform tightening force helps avoid local stress concentration, reduces local deformation and damage to the rubber material, and ensures long-term sealing performance.

[0043] The clamps are typically adjusted in inner diameter using mechanisms such as screws or springs. This design allows on-site workers to easily adjust the clamp's tightness according to the actual outer diameter of the fiber optic cable 10 or downlead duct 90, ensuring a tight fit of the sealing sleeve. Furthermore, the clamps are easy and quick to install and remove, facilitating on-site operation and subsequent maintenance.

[0044] The clamp has a wide range of inner diameter adjustment, which can accommodate optical cables 10 and downleaders 90 of different diameters, thereby improving the versatility and adaptability of the sealing sleeve. This means that even if there are slight changes in the size of the optical cable 10 or downleader 90 during construction, the clamp can be adjusted to ensure the sealing and stability of the device.

[0045] The clamp, through its ring-shaped design and fastening mechanism, effectively reduces the risk of the sealing sleeve detaching from the optical cable 10 or the downlead tube 90 due to external factors such as wind and vibration. The clamp's tightening force resists these external forces, maintaining the stability of the sealing device and extending the duration of the sealing effect. The clamp ensures a tight fit between the sealing sleeve and the surface of the optical cable or downlead tube, maintaining good sealing performance even under harsh weather conditions (such as high temperature, low temperature, and humidity). Furthermore, the clamp's material and structural design ensure that it will not easily be damaged or fail during prolonged use.

[0046] If any part of the sealing sleeve, fiber optic cable 10, or downlead tube 90 needs to be replaced or maintained, the use of clamps can significantly improve the efficiency of this process. Simply loosen the clamps to easily remove the sealing sleeve from the fiber optic cable 10 or downlead tube 90 for necessary inspection, replacement, or repair. After completion, reinstall and tighten the clamps. The entire process is quick and causes minimal damage to the fiber optic cable 10 and downlead tube 90.

[0047] In some alternative embodiments, the first semi-cylinder 20 and the second semi-cylinder 30 are made of either rubber or silicone. Rubber and silicone materials have good elasticity and weather resistance, and can maintain good sealing performance under various temperature and humidity conditions, making them suitable for sealing optical cable downpipes under extreme climatic conditions.

[0048] Both rubber and silicone have good elasticity and resilience, enabling them to fit tightly against the surfaces of the optical cable 10 and the downlead tube 90, forming an effective seal. This material property allows the first half-cylinder 20 and the second half-cylinder 30 to adapt to the shapes of the optical cable 10 and the downlead tube 90 under the action of fasteners 40 (such as clamps), ensuring a good seal even on slightly irregular surfaces, preventing the infiltration of rainwater, moisture, and other external factors, and protecting the optical cable 10 from damage.

[0049] Rubber and silicone materials possess excellent weather resistance, enabling them to withstand the effects of environmental factors such as ultraviolet radiation, temperature changes, and humidity, maintaining long-term stability and durability. This means that even under various harsh outdoor conditions, such as extreme temperatures (high or low temperatures), continuous humid environments, or strong sunlight, the first half-cylinder 20 and the second half-cylinder 30 can still maintain their elasticity, sealing, and structural integrity, providing durable protection for the optical cable 10.

[0050] In the field of power communications, optical cables may be exposed to environments containing chemicals, such as salt spray and acid rain. Rubber and silicone materials have good chemical stability, which can resist these corrosive environments, maintain the stability of material performance, extend the service life of sealing devices, and reduce the frequency of maintenance and replacement.

[0051] The flexibility of the rubber and silicone materials allows the first half-cylinder 20 and the second half-cylinder 30 to adapt to minor dimensional changes in the optical cable 10 and the down-lead tube 90. Even if some unexpected dimensional mismatches occur during installation, they can be compensated for by the deformation of the materials themselves, ensuring a tight installation and good sealing effect of the device.

[0052] The lightweight properties of rubber and silicone make the first and second semi-cylinder columns 20 and 30 easier to handle and install. Their flexibility also facilitates adjustment and positioning during installation. During maintenance or replacement, the flexibility of the materials reduces damage to the optical cable 10, making the entire process safer and more efficient.

[0053] Rubber and silicone materials maintain their physical properties over a wide temperature range, without becoming too hard or too soft due to temperature changes, thus preventing loss of sealing or securing capabilities. This temperature adaptability is a crucial characteristic for the protection of outdoor optical fiber communication cables, ensuring stable operation of the sealing sleeve under different seasons and climatic conditions.

[0054] In summary, the first half-cylinder 20 and the second half-cylinder 30 are made of rubber or silicone materials, which can significantly improve the sealing performance, weather resistance, and corrosion resistance of the sealing device, while maintaining good flexibility and easy installation and maintenance, providing an efficient, reliable, and durable protection solution for optical cables.

[0055] In some alternative embodiments, please refer to Figure 1 The sealing device for the optical cable downpipe also includes a water accumulation detection component, a water accumulation removal component 60, and a power supply component 70. A portion of the water accumulation detection component is located inside the downpipe 90, and it is used to detect water accumulation within the downpipe 90. A portion of the water accumulation removal component 60 is also located inside the downpipe 90, and it is used to remove water accumulation within the downpipe 90. The water accumulation detection component and the water accumulation removal component 60 are signal-connected. The power supply component 70 is located above the sealing sleeve and is connected to both the water accumulation detection component and the water accumulation removal component 60, providing power to both components. This design enables the device to automatically detect and remove water accumulation, effectively preventing damage to the optical cable due to water accumulation. It is suitable for the protection of optical cable downpipes that require long-term unattended operation, such as communication facilities in remote areas.

[0056] A portion of the water accumulation detection component is located inside the downpipe, enabling real-time monitoring of water accumulation. Typically, this component includes devices such as water immersion sensors, which can sensitively detect the presence of moisture, even very small amounts. This feature allows the sealing device to proactively respond to environmental changes, preventing potential damage to the fiber optic cable caused by water accumulation.

[0057] A portion of the water removal component 60 is also located within the downpipe 90. Once the water detection component issues a water accumulation signal, the water removal component 60 immediately activates, pumping out the accumulated water via the drain pump 62 and discharging it through the drain pipe 61. This design eliminates the need for regular manual inspections and removal of accumulated water, improving maintenance efficiency and reducing the risk of fiber optic cable failures due to untimely water removal.

[0058] The water accumulation detection component is signal-connected to the water accumulation removal component 60, meaning that once water accumulation is detected, the water accumulation removal component 60 can be remotely triggered to start. This feature is particularly suitable for fiber optic cable downpipes with dispersed sites and remote geographical locations. Maintenance personnel do not need to go to the site in person to respond to water accumulation problems in a timely manner through remote operation, effectively improving response speed and efficiency.

[0059] The power supply component 70 is located above the sealing sleeve and connects to the water accumulation detection component and the water accumulation removal component 60, providing a stable power supply to both components. Considering outdoor working conditions, the power supply component 70 typically uses solar panels or other sustainable energy sources to ensure that the sealing device can continue to operate, monitor, and remove water accumulation even without an external power source.

[0060] By automating water accumulation detection and removal, the sealing device for fiber optic cable downpipes reduces reliance on manual labor and lowers maintenance costs. This design means that maintenance personnel can dedicate more time and resources to other tasks that require more human intervention, thus improving overall maintenance efficiency.

[0061] Water accumulation is one of the common sources of failure in downconduit 90, especially in winter when it freezes or is damp for extended periods. Water accumulation can degrade the performance of optical cable 10 and even interrupt communication. The use of water accumulation detection and removal components can effectively prevent and resolve water accumulation problems, enhancing the stability and reliability of the communication system.

[0062] By promptly detecting and removing accumulated water, the sealing device of the optical cable downpipe can protect the optical cable from the effects of moisture erosion, reduce the possibility of optical cable aging and damage, thereby indirectly extending the service life of the optical cable and reducing the long-term operation and maintenance costs of the communication network.

[0063] In some alternative embodiments, please refer to Figure 1The water accumulation removal component 60 includes a drain pipe 61 and a drain pump 62. The drain pipe 61 is located inside the downpipe 90, with its inlet end at the bottom and its outlet end extending through a sealing sleeve. The drain pump 62 is located at the inlet end of the drain pipe 61 and is connected to the power supply component 70 and the water accumulation detection component. This intelligent drainage system can respond promptly to water accumulation and automatically drain water, reducing the need for manual maintenance. It is suitable for water accumulation removal in fiber optic cable downpipes requiring automated management, such as the maintenance of large communication networks. The drain pump 62 is connected to the water accumulation detection component. Once the detection component detects water accumulation in the downpipe 90, the pump 62 automatically starts, drawing water from the inlet end of the drain pipe 61 and discharging it out of the downpipe 90 through the outlet end, achieving automated drainage. This process requires no manual intervention, effectively improving the timeliness and efficiency of water accumulation treatment.

[0064] The inlet of the drain pipe 61 is designed at the bottom of the downpipe 90, which is the location where water is most likely to accumulate. This design ensures that the drain pump 62 can drain water from the deepest and most concentrated area, improving the efficiency and thoroughness of water removal and preventing long-term water retention from damaging the optical cable.

[0065] The signal connection between the water accumulation detection component and the drainage pump 62 not only enables automated drainage but also supports remote operation. Maintenance personnel can receive water accumulation signals through a remote monitoring system or remote alarm system and remotely start the drainage pump 62 to drain water. Even when maintenance personnel cannot immediately reach the site, water accumulation issues can be addressed promptly, protecting the fiber optic cable 10. The automated water removal function reduces reliance on manual labor; maintenance personnel no longer need to periodically check the water accumulation in the downpipe 90 and manually drain it, saving significant labor costs and time, making maintenance work more efficient.

[0066] Water accumulation is a common factor leading to performance degradation and malfunctions in optical cables, especially under conditions of icing or prolonged dampness. The automatic drainage function of the water removal component 60 effectively prevents water corrosion of the optical cable, enhances the overall reliability of the optical cable downpipe sealing device, and ensures the stable operation of the communication network. By promptly removing water, long-term corrosion of the optical cable is avoided, reducing the risk of aging and damage, indirectly extending the cable's lifespan, and lowering the long-term maintenance costs of the communication network.

[0067] The drainage pump 62 is connected to the power supply component 70, which is designed like a solar panel. This ensures that the water removal component 60 can still work without an external power source, improving the adaptability and independence of the device in complex outdoor environments.

[0068] In some alternative embodiments, the drainage pump 62 is a miniature water pump, for example, with a minimum flow rate of 50 liters per hour and a head of not less than 10 meters. This high-efficiency miniature water pump can quickly and effectively remove accumulated water from the downpipe, making it suitable for scenarios requiring rapid drainage, such as fiber optic cable downpipe protection during rainy seasons. The high-efficiency configuration of the miniature water pump effectively removes accumulated water from the downpipe, making it particularly suitable for high-risk flooding scenarios such as rainy seasons, effectively protecting the fiber optic cable and reducing communication interruptions caused by water accumulation.

[0069] In some alternative embodiments, please refer to Figure 1 The water accumulation detection component includes a water accumulation detection sensor 80 and a signal transmitting unit. A portion of the water accumulation detection sensor 80 is located inside the downpipe 90 and is connected to the power supply component 70. The signal transmitting unit is electrically connected to the power supply component 70, signal-connected to the water accumulation detection sensor 80, and signal-connected to the water accumulation removal component 60. The accurate detection by the water accumulation sensor 80 and the instantaneous feedback from the signal transmitting unit ensure the timely activation of the water accumulation removal component 60. This is suitable for scenarios requiring real-time monitoring of water accumulation in the downpipe 90, such as fiber optic cable downpipe protection in data centers.

[0070] A portion of the water accumulation detection sensor 80 is located inside the drain pipe 90, enabling real-time monitoring of water accumulation within the drain pipe 90. This type of sensor is typically highly sensitive to moisture; upon detection, it immediately generates a signal, ensuring early detection of water accumulation and saving valuable time for subsequent handling. A signal transmitting unit is connected to the water accumulation detection sensor 80. When the sensor detects water accumulation, the unit automatically transmits the signal to a remote monitoring center or maintenance personnel via wireless communication (such as GSM). This design avoids the delays of traditional manual checks, ensures timely communication of water accumulation information, and improves response speed.

[0071] The signal transmitting unit is connected to the water accumulation removal component 60 (such as a drainage pump), meaning that when the water accumulation signal is received by the remote monitoring center, maintenance personnel can remotely activate the water accumulation removal component 60 to handle the water accumulation problem without having to be physically present on-site. This remote operation capability greatly improves maintenance efficiency, especially in remote locations, saving a significant amount of time and resources.

[0072] The water accumulation detection sensor 80 and signal transmitting unit are connected to the power supply component 70, ensuring the power requirements of the water accumulation detection component during detection and signal transmission. Typically, the power supply component 70 uses a solar panel or small battery, guaranteeing continuous operation of the water accumulation detection component even without an external power source, thus improving system reliability. By promptly detecting and removing water accumulation, the water accumulation detection component effectively prevents moisture from corroding the optical cable, reducing the risk of damage, especially preventing physical damage to the optical cable that may be caused by icing in winter.

[0073] In some alternative embodiments, the water accumulation detection sensor 80 includes a water immersion sensor wound around the optical cable 10. A portion of the water immersion sensor is located between the sealing sleeve and the optical cable 10, and one end of the water immersion sensor extends from the top of the sealing sleeve and connects to the power supply component 70. This arrangement of the water immersion sensor enables comprehensive monitoring of water accumulation around the optical cable, ensuring the safety of the optical cable. It is suitable for scenarios requiring comprehensive protection of the optical cable, such as the protection of optical cable downpipes for important communication lines.

[0074] In some alternative embodiments, the water immersion sensor employs a capacitive sensor. Capacitive sensors offer high sensitivity and reliability, accurately detecting water accumulation and are suitable for water protection of downpipes requiring high-precision detection, such as fiber optic cable protection in communication facilities.

[0075] The water accumulation detection component also includes a GSM smart alarm unit, which is electrically connected to the water accumulation detection sensor 80 or the signal transmitting unit. When the water accumulation detection sensor 80 detects water accumulation, it transmits a water accumulation signal to the GSM smart alarm unit, causing the GSM smart alarm unit to sound an alarm. The GSM smart alarm unit uses an information transmission unit compatible with both GSM and 4G / 5G mobile communication networks. This design enables the device to send alarm information via mobile networks, making it suitable for scenarios requiring remote monitoring and alarm functions, such as fiber optic cable downpipe protection in urban surveillance networks.

[0076] The GSM smart alarm device promptly alerts maintenance personnel to take action, and the maintenance personnel can remotely activate the water removal component 60 to remove the water accumulated on the fiber optic cable.
