Description

Technical Field

[0001] This invention relates to the field of optical cable technology, and specifically to a micro-tube OPGW optical cable. Background Technology

[0002] Microtube bundled tubes are composite tubes composed of an HDPE outer tube and a silicon core microtube. They are mainly used in the fields of micro-optical cable laying and communication engineering protection. They are based on the principle of total internal reflection of optical fiber and the transmission characteristics of light. When a beam of light enters from one end of an optical fiber, due to the difference between the refractive index inside the optical fiber and the external environment, the light will undergo total internal reflection continuously inside the optical fiber, thus transmitting along the optical fiber and realizing signal transmission. The signal transmission of microtube bundled tubes is related to whether the tube is damp.

[0003] For example, micro-tube OPGWs are often installed on outdoor windows, but they are vulnerable to extreme weather conditions such as strong winds, icing, and line galloping. The junction box in contact with the micro-tube is the weakest point in the seal, and it may become fatigued and loose due to repeated stretching in the weather. This can easily lead to moisture inside, and if not dealt with in time, it can easily cause signal transmission loss, making it difficult to provide a good user experience. Summary of the Invention

[0004] This invention provides a micro-tube OPGW optical cable that utilizes externally introduced force to prevent excessive internal moisture accumulation, thereby improving dryness and preventing dampness.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] In a first aspect, a micro-tube OPGW optical cable includes: a tubing, an elastic buffer layer disposed on the inner side of the tubing, a metal layer fixedly installed on the inner layer of the elastic buffer layer, and an optical cable tube disposed on the inner side of the metal layer, characterized in that a vent is disposed through the outer side of the tubing, and an annular layer is disposed on the inner wall of the metal layer;

[0007] A moisture-proof section is installed on the inner wall of the metal layer and on the outside of the tubing for moisture protection.

[0008] The moisture-proof part includes a float and a sealing component. The float is disposed on the inner wall of the metal layer and is connected to the sealing component, which is disposed on the inner wall of the annular layer.

[0009] Furthermore, the float component includes:

[0010] The upper limit layer is positioned above the ring layer;

[0011] The lower limit layer is located below the annular layer;

[0012] Multiple recessed holes are provided above the upper limit layer.

[0013] Furthermore, the float component also includes:

[0014] An elastic strip is attached below the recessed hole.

[0015] Connecting strip one is fixedly installed at the bottom end of the elastic strip;

[0016] There are multiple cotton balls, which are arranged between the connecting strips and are evenly distributed.

[0017] Furthermore, the sealing element includes:

[0018] The mounting base is positioned above the lower limit layer;

[0019] The column is set on top of the mounting base.

[0020] Furthermore, the sealing component also includes:

[0021] The rotating ring is mounted on the outside of the column.

[0022] The V-shaped bracket is fixedly installed on the outside of the rotating ring.

[0023] Furthermore, the sealing component also includes:

[0024] The sealing component has a sliding groove inside the V-shaped frame that can be adapted to the rotating ring;

[0025] The curved strip is fixedly connected to one end of the V-shaped frame.

[0026] A flat-ground flexible plate is fixedly installed at the top of the curved strip;

[0027] The limiting component is located on the inner side of the lower limiting layer to facilitate the introduction of external gas through the vent.

[0028] Furthermore, the limiting component includes:

[0029] Multiple vertical pieces are arranged in the inner cavity of the lower limit layer;

[0030] Multiple springs are fixedly installed below the upright plate.

[0031] Furthermore, the limiting component also includes:

[0032] The ventilation tubes are multiple in number and are located inside the lower limit layer, with a slot at one end that is adapted to the spring.

[0033] Connecting strip two is installed on one side of the vent pipe;

[0034] One side of the upright plate is connected to the ventilation cylinder.

[0035] The above-described solution of the present invention has at least the following beneficial effects:

[0036] By squeezing the V-shaped frame with a cotton ball, and then through the combined action of the V-shaped frame, the upright plate, and the compression spring, the ventilator is moved to the recessed position of the upright plate, thus creating ventilation. The combined action of the ventilator, the vent pipe, and the cotton ball accelerates the drying of the exterior and creates a reverse blowing effect, which helps to disperse the internal moisture and achieve an automatic moisture-proof effect.

[0047] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0048] like Figures 1 to 8 As shown, a micro-tube OPGW optical cable includes: a tubing 1, an elastic buffer layer 2 disposed on the inner side of the tubing 1, a metal layer 3 fixedly installed on the inner layer of the elastic buffer layer 2, and an optical cable tube 4 disposed on the inner side of the metal layer 3. The feature is that a venting cylinder 5 is disposed through the outer side of the tubing 1, and an annular layer 6 is disposed on the inner wall of the metal layer 3.

[0049] A moisture-proof section is installed on the inner wall of the metal layer 3 and on the outer side of the tubing 1 for moisture protection.

[0050] The moisture-proof part includes a float and a sealing component. The float is installed on the inner wall of the metal layer 3 and is connected to the sealing component. The sealing component is installed on the inner wall of the annular layer 6.

[0051] Specifically, the ventilation cylinder 5 passes through the hose 1, the elastic buffer layer 2, and the metal layer 3 and extends to the outside of the optical cable tube 4. One end of the hose 1 is used to connect to the junction box. The elastic buffer layer 2 prevents the hose from being twisted and deformed by objects when encountering sudden weather or situations. In addition, the hose 1 and the elastic buffer layer 2 can isolate moisture and prevent moisture from seeping in from the outside.

[0052] In practical application, the following steps are taken: First, one end of the hose 1 is connected to the hole in the junction box. The optical cable tube 4 is then stripped to extend the cable into the junction box to complete the connection. Since the hole in the junction box will be stuck on the outside of the hose 1, it is difficult to completely seal one side of the hose 1 with the junction box. At this time, moisture can easily seep into the metal layer 3 and the area between the optical cable tube 4 and the metal layer 3 from between the junction box and the hose 1. When the moisture seeps into the metal layer 3 and the area between the optical cable tube 4 and the metal layer 3, it enters the annular layer 6 from the inner cavity of the metal layer 3. The wind enters the annular layer 6 through the vent 5 and finally discharges the moisture in the annular layer 6 in the opposite direction to prevent the moisture from interfering with the signal transmission of the optical cable tube 4.

[0053] like Figure 5 As shown, the float component includes:

[0054] Upper limit layer 61 is positioned above ring layer 6;

[0055] The lower limit layer 62 is located below the annular layer 6;

[0056] Multiple recessed holes 63 are provided above the upper limit layer 61;

[0057] Elastic strip 64 is elastically connected below the recessed hole 63;

[0058] Connecting strip 65 is fixedly installed at the bottom end of elastic strip 64;

[0059] Cotton balls 66, in multiple quantities, are arranged between the connecting strips 65 and are evenly distributed.

[0060] Specifically, the recessed hole 63 facilitates the centralized collection and treatment of moisture; the elastic strip 64 is elastically connected to the recessed hole 63 to support the cotton ball 66; the connecting strip 65 is used to fix the cotton ball 66.

[0061] In practical application, moisture first enters from the inner wall of the metal layer 3, then moves towards the inside of the recessed hole 63, and finally enters the interior of the annular layer 6 through the recessed hole 63. During this process, when there is less moisture, it will soak the cotton ball 66 at the local location. The cotton ball 66 at the local location becomes heavier. After the cotton ball 66 becomes heavier, it will move downward along the interior of the annular layer 6 under the support of the connecting strip 65, and will rub against the annular layer 6, thereby producing a local vibration sound, so that people can understand the moisture penetration at the vibration location.

[0062] When there is a lot of moisture, the moisture will come into contact with all the cotton balls 66 below. After being affected by the moisture, the multiple cotton balls 66 gradually move downwards. As the cotton balls 66 move downwards, they vibrate as a whole, which reminds people to take timely precautions against moisture.

[0063] like Figures 5 to 6 As shown, the sealing component includes:

[0064] Mounting base 67 is positioned above the lower limit layer 62;

[0065] The column 68 is set on top of the mounting base 67;

[0066] Rotating ring 69 is rotatably mounted on the outside of column 68;

[0067] V-shaped bracket 60 is fixedly installed on the outside of rotating ring 69;

[0068] The sealing component V-shaped bracket 60 has a sliding groove inside that can be adapted to the rotating ring 69.

[0069] The curved strip 601 is fixedly connected to one end of the V-shaped frame 60.

[0070] The flat grinding plate 602 is fixedly installed at the top of the curved strip 601;

[0071] A limiting component is located inside the lower limiting layer 62 to facilitate the introduction of external gas through the vent 5.

[0072] Specifically, the rotating ring 69 is easy to rotate on the outside of the column 68 to finely adjust the direction of the V-shaped frame 60, so that the other V-shaped frame 60 can move in a rotating range when it is tilted up; the flat grinding soft plate 602 is made of rubber, so that it is not easy to cause bumps due to friction when blocking; the curved strip 601 is used to compensate for the distance that the V-shaped frame 60 cannot reach the hole 63 when it is tilted up.

[0073] In practical application, when moisture is concentrated, the area around the recessed hole 63 is easily corroded by continuous moisture, affecting its service life. When the cotton ball 66 is wetted and moves downward along the inside of the annular layer 6 under the action of gravity, the cotton ball 66 will press down on one side of the V-shaped frame 60. There is a gap between the V-shaped frame 60 and the mounting base 67. With the support of the column 68 and the center position of the V-shaped frame 60, the other side of the V-shaped frame 60 will be raised. The V-shaped frame 60 pushes the curved strip 601 and the flat grinding soft plate 602 to move. After the flat grinding soft plate 602 is raised, it slides to the position below the recessed hole 63, which will block the position of moisture in the recessed hole 63 to prevent continuous moisture collection from causing damage.

[0074] Furthermore, when the V-shaped frame 60 is tilted up, it can rotate slightly, preventing it from being completely sealed off and unable to concentrate moisture in time.

[0075] like Figures 6 to 7 As shown, the limiting component includes:

[0076] Multiple vertical pieces 603 are disposed in the inner cavity of the lower limit layer 62;

[0077] Multiple springs 604 are fixedly installed below the upright plate 603.

[0078] The limiting components also include:

[0079] The ventilation pipe 606 has multiple parts, is disposed inside the lower limit layer 62, and has a slot at one end that is adapted to the spring 604;

[0080] Connecting strip 2 607 is installed on one side of vent pipe 606;

[0081] One side of the upright plate 603 is connected to the ventilation cylinder 5.

[0082] Specifically, the side of the upright piece 603 near the ventilator 5 is concave and convex, which facilitates the ventilation or closure of the ventilator 5 by matching the downward movement distance of the cotton ball 66; the spring 604 facilitates the reset of the upright piece 603; the connecting strip 607 facilitates the connection of multiple ventilator tubes 606 together, and the connecting strip 607 is located outside the mounting base 67 and does not obstruct the mounting base 67; the top and one side of the ventilator tube 606 are provided with through holes to introduce gas upwards for air-cooling and drying of the cotton ball 66.

[0083] In practical application, after the cotton ball 66 has collected all the moisture, it needs to be automatically dehumidified and reset for easy reuse. Specifically, when the cotton ball 66 moves downwards, it presses against one side of the V-shaped frame 60. After the V-shaped frame 60 moves downwards a small distance, the cotton ball 66 presses against the upright plate 603. The upright plate 603 then presses downwards, resetting the spring 604. By default, the ventilator 5 is in contact with one side of the upright plate 603. When the upright plate 603 moves downwards, the ventilator 5 moves... When the air reaches the recessed position of the upright plate 603, ventilation is formed. The air introduced from outside the air cylinder 5 blows into the air pipe 606 and pushes the cotton ball 66 in the opposite direction through the top of the air pipe 606, accelerating the drying of its exterior and forming a reverse blowing, which helps to disperse the internal moisture, so as to form an automatic moisture-proof effect. At the same time, there is still moisture between the metal layer 3 and the optical cable tube 4. At this time, since the air cylinder 5 can extend to the inside of the metal layer 3 through the hose 1, the air force will blow in the opposite direction to adhere to the moisture, accelerating its drying.

[0084] Working principle: This micro-tube OPGW optical cable works in a multi-layer structure, and its core is to ensure stable optical cable signal transmission through multiple protection and moisture-proof design.

[0085] From an overall structural perspective, the outermost tubing 1 is connected to the junction box at one end, and it, together with the inner elastic buffer layer 2, can initially isolate external moisture. The elastic buffer layer 2 can also prevent the optical cable from being deformed due to compression or twisting. Inside the metal layer 3, there is an optical cable tube 4, and a vent 5 that runs through the tubing 1, the elastic buffer layer 2, and the metal layer 3, providing a channel for internal air circulation and moisture discharge.

[0086] In terms of moisture protection, the float and sealing components of the moisture-proof section play a crucial role. When moisture enters the metal layer 3 and the area around the optical cable tube 4 through the gap between the hose 1 and the junction box, it first enters the annular layer 6. At this time, the airflow introduced by the vent 5 can reverse the flow of moisture from the annular layer 6, reducing interference with the signal of the optical cable tube 4.

[0087] In the float assembly, the recessed holes 63 in the uppermost layer 61 collect moisture. When the moisture level is low, the cotton balls 66 absorb moisture, become heavier, and move downwards, rubbing against the annular layer 6 to generate local vibration sounds, indicating the local moisture level. When the moisture level is high, multiple cotton balls 66 move downwards, generating overall vibration sounds, reminding the user to take timely precautions against moisture.

[0088] The sealing component works in conjunction with the float component. When the cotton ball 66 moves downward, it presses down on one side of the V-shaped frame, causing the other side to lift up. This moves the flat grinding plate 602 to block the recessed hole 63, reducing the continuous intrusion of moisture. The slight rotation of the V-shaped frame also prevents complete sealing, which would affect the concentrated treatment of moisture. At the same time, the downward movement of the cotton ball 66 compresses the vertical plate 603, creating ventilation between the ventilator 5 and the vertical plate 603. External air blows through the vent pipe 606 onto the cotton ball 66 to accelerate drying and also disperses the moisture between the metal layer 3 and the optical cable tube 4, achieving automatic moisture prevention and reset, and ensuring the stable operation of the optical cable.
