[0002] The water permeability of optical cables is an important indicator of optical cables. If the water permeability of optical cables is unqualified, it is easy to increase the attenuation of optical cables and affect the communication quality.

The water permeability test of optical cables is generally carried out with pure water, and the water permeability test of optical cables is completed with pure water of a certain height. Since optical cables may be used at the seaside or in saline-alkali land, some optical cables also need to be tested for salt water permeability.

[0003] However, in the related art, the test device for optical cable water seepage test is not compatible with salt water and pure water water seepage detection, resulting in a cumbersome switching process when performing salt water testing and pure water testing, which requires switching on different devices.

[0037] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Combine the following Figures 1 to 4 The optical cable water seepage detection device of the present application is described.

[0039] Figure 1 The schematic diagram of the pipeline structure of the optical cable water seepage detection device provided in the embodiment of the present application is illustrated as follows: Figure 1 As shown, the optical cable water leakage detection device comprises at least two storage boxes 1 and a water leakage detection member 2. The storage box 1 is used to be filled with detection liquid, and the water leakage detection member 2 is connected to the storage box 1 through a connecting pipe assembly 3, and the connecting pipe assembly 3 is used to connect the water leakage detection member 2 and one of the storage boxes 1, or connect the water leakage detection member 2 and the other storage box 1.

[0040] According to the optical cable water seepage detection device of the embodiment of the present application, the water seepage detection component 2 and one of the storage boxes 1 are connected through the connecting pipe assembly 3, or the water seepage detection component 2 and another storage box 1 are connected through the connecting pipe assembly 3 to control the connection state of the connecting pipe assembly 3, so that the optical cable water seepage detection device can switch the water seepage detection component 2 to be connected with one of the storage boxes 1 or the other storage box 1 as needed.

[0041] Furthermore, when it is necessary to perform water seepage detection on the optical cable using at least two detection liquids, one of the detection liquids can be filled into one of the storage boxes 1, and the other detection liquid can be filled into the other storage box 1. The connection state between the water seepage detection component 2 and the at least two storage boxes 1 is switched through the connecting pipe assembly 3, so as to realize the switching of the detection liquid in the water seepage detection component 2, so that the optical cable water seepage detection device can be compatible with optical cable water seepage detection using at least two detection liquids, and effectively improve the detection efficiency of the optical cable water seepage detection device when performing water seepage detection using at least two detection liquids.

[0042] Exemplarily, the detection liquid can be pure water or salt water. When the optical cable needs to be tested for pure water seepage and salt water seepage, pure water can be filled into one of the storage boxes 1, and salt water can be filled into the other storage box 1. Then, the connection state between the two storage boxes 1 and the water seepage detection member 2 is switched through the connecting pipe assembly 3 to switch the detection liquid in the water seepage detection member 2, thereby completing the pure water seepage and salt water seepage detection of the optical cable.

[0043] The salt water can be obtained according to the actual use environment of the optical cable. The salt water can be artificial seawater, 3.5% salinity salt water, or other concentrations of salt water to meet actual detection needs.

[0044] In addition, when it is necessary to adjust the height of the water column for water seepage detection, the liquid level of the detection liquid can be adjusted by adding detection liquid to the storage box 1, or the detection liquid in the storage box 1 can be discharged, thereby realizing the optical cable water seepage test of the specified water column height to meet the customer's requirements for water seepage performance detection.

[0045] In one embodiment of the present application, Figure 1 As shown, the connecting pipe assembly 3 includes a first connecting branch 31 , a first end of the first connecting branch 31 is connected to at least two storage boxes 1 in an on-off manner, and a second end of the first connecting branch 31 is connected to the water seepage detection component 2 in an on-off manner.

[0046] It can be understood that when it is necessary to perform a water seepage test using the detection liquid in one of the storage boxes 1, the first connecting branch 31 can be connected to one of the storage boxes 1, while the first connecting branch 31 can be disconnected from the other storage box 1, and the second end of the first connecting branch 31 can be connected to the water seepage detection member 2 to connect the water seepage detection member 2 to one of the storage boxes 1, thereby performing a water seepage test using the detection liquid in one of the storage boxes 1.

[0047] When it is necessary to use the detection liquid in another storage box 1 to perform a water seepage test, the water seepage detection member 2 is connected to the other storage box 1 through the first connecting branch 31, so that the water seepage test is performed using the detection liquid in the other storage box 1.

[0048] Exemplarily, in the present embodiment, a first connecting branch 31 may be provided, and when it is necessary to switch the connection between the water seepage detection component 2 and one of the storage tanks 1 to the connection between the water seepage detection component 2 and the other storage tank 1, the connection between one of the storage tanks 1 and the first end of the first connecting branch 31 may be disconnected, and at the same time, the first end of the first connecting branch 31 may be connected to the other storage tank 1, thereby switching one of the two storage tanks 1 to be connected to the water seepage detection component 2 through the first connecting branch 31, so that the water seepage detection component 2 can realize the switching of water seepage detection of two detection liquids.

[0049] For example, in this embodiment, the number of the first communication branches 31 is the same as the number of the storage boxes 1. For example, when the number of the storage boxes 1 is 2, the number of the first communication branches 31 is also 2. At this time, one of the first communication branches 31 can be connected to one of the storage boxes 1, and the other first communication branch 31 can be connected to the other storage box 1. Then, when it is necessary to switch the connection between the water seepage detection member 2 and one of the storage boxes 1 to the connection between the water seepage detection member 2 and the other storage box 1, the connection between the first communication branch 31 and the water seepage detection member 2 can be disconnected, and the other first communication branch 31 can be connected to the water seepage detection member 2, so as to realize the switching between the water seepage detection member 2 and the two storage boxes 1.

[0050] In one embodiment of the present application, Figure 1 As shown, the connecting pipe assembly 3 also includes a second connecting branch 32. Two first connecting branches 31 are provided, and the first end of the second connecting branch 32 is connected to the second ends of the two first connecting branches 31, and the second end of the second connecting branch 32 is connected to the water seepage detection member 2.

[0051] It can be understood that by connecting the first end of the second connecting branch 32 with the second ends of the two first connecting branches 31, and connecting the second end of the second connecting branch 32 with the water seepage detection component 2, the connecting state between the water seepage detection component 2 and the two storage boxes 1 can be switched by switching the connecting state between the second connecting branch 32 and one of the first connecting branches 31 or the other connecting branch.

[0052] Specifically, taking the case where the detection liquid in one storage box 1 is pure water and the detection liquid in the other storage box 1 is salt water as an example, when it is necessary to perform pure water seepage detection on the optical cable, one of the first connecting branches 31 and the second connecting branch 32 can be connected, and at the same time, the connection between the other first connecting branch 31 and the other storage box 1 is disconnected to connect one of the storage boxes 1 with the water seepage detection component 2, so that pure water flows into the water seepage detection component 2, and the optical cable can be tested for pure water seepage.

[0053] When it is necessary to perform salt water seepage detection on the optical cable, the other first connecting branch 31 and the second connecting branch 32 are connected, and the connection between one of the first connecting branches 31 and one of the storage boxes 1 is disconnected, so that the salt water in the other storage box 1 can be introduced into the water seepage detection member 2, so as to realize salt water seepage detection on the optical cable.

[0054] Furthermore, a first control valve 33 is provided at the first end of the first connecting branch 31, and the first control valve 33 is used to control the on-off connection between the first connecting branch 31 and the storage box 1. A second control valve 34 is provided at the second end of the second connecting branch 32, and the second control valve 34 is used to control the on-off connection between the second connecting branch 32 and the water seepage detection member 2.

[0055] It can be understood that when two first communication branches 31 are provided, each first communication branch 31 is provided with a first control valve 33. When it is necessary to switch the connection between the water seepage detection member 2 and one of the storage tanks 1 to the connection between the water seepage detection member 2 and the other storage tank 1, the first control valve 33 in one of the first communication branches 31 can be disconnected, and the first control valve 33 in the other first communication branch 31 can be connected, so as to realize the switching of the two first communication branches 31.

[0056] When it is necessary to replace the sample in the water seepage detection component 2 and to perform water seepage detection with the same detection liquid, the second control valve 34 can be used to control the second connecting branch 32 to disconnect from the water seepage detection component 2, and the sample and detection liquid in the water seepage detection component 2 can be removed for subsequent water seepage detection. At the same time, there is no need to switch the storage box 1, thereby reducing the detection steps when switching samples.

[0057] It should be noted that the on-off connection between the first connecting branch 31 and the storage tank 1 is not limited to the on-off connection through the first control valve 33, and a drainage switch may be provided at the water outlet of the storage tank 1, and the on-off connection between the first connecting branch 31 and the storage tank 1 may be controlled by the drainage switch of the storage tank 1. Similarly, a water inlet switch may be provided inside the water seepage detection member 2, and the on-off connection between the second connecting branch 32 and the water seepage detection member 2 may be controlled by the water inlet switch.

[0058] In one embodiment of the present application, the two first communication branches 31 are connected to the second communication branch 32 via the three-way valve 35. Furthermore, by controlling the connection state between the three-way valve 35 and the first control valve 33 in the two first communication branches 31, the three-way valve 35 and the first control valve 33 cooperate with each other to realize the switching of the connection state between the water seepage detection member 2 and the two storage boxes 1.

[0059] Specifically, the first interface of the three-way valve 35 is connected to the first end of the second connecting branch 32 , the second interface of the three-way valve 35 is connected to one of the first connecting branches 31 , and the third interface of the three-way valve 35 is connected to another first connecting branch 31 .

[0060] When it is necessary to connect the water seepage detection component 2 with one of the storage boxes 1, the first interface of the three-way valve 35 can be connected with the second interface of the three-way valve 35, and the first control valve 33 of one of the first connecting branches 31 can be connected, and the first control valve 33 of the other first connecting branch 31 can be disconnected, so as to connect the water seepage detection component 2 with one of the storage boxes 1, so as to perform a water seepage test using the detection liquid in one of the storage boxes 1.

[0061] When it is necessary to connect the water seepage detection component 2 with another storage tank 1, the first interface of the three-way valve 35 is connected with the third interface of the three-way valve 35, and the first control valve 33 of another first connecting branch 31 is connected, and the first control valve 33 of one first connecting branch 31 is disconnected, so as to connect the water seepage detection component 2 with another storage tank 1, so as to perform a water seepage test using the detection liquid in the other storage tank 1.

[0062] In one embodiment of the present application, in order to further improve the convenience of conducting water seepage tests on optical cables at different water column heights, soft water pipes can be used for the second connecting branch 32 and the two first connecting branches 31 to further increase the water column height by adjusting the extension length of the soft water pipe by utilizing the extension performance of the soft water pipe.

[0063] Of course, in order to increase the water column height of the detection liquid, the second connecting branch 32 and the two first connecting branches 31 are not limited to soft water pipes, but can also be other plastic pipes such as PVC, and multiple plastic pipes are spliced ​​together to achieve the adjustment of the extension length of the first connecting branch 31 and the second connecting branch 32.

[0064] In one embodiment of the present application, Figure 2 The first connection structure schematic diagram of the detection sample and the water seepage detection member provided in the embodiment of the present application is illustrated. Figure 3 The second connection structure schematic diagram of the detection sample and the water seepage detection member provided in the embodiment of the present application is illustrated, Figure 2 and Figure 3 As shown, the water seepage detection component 2 is provided with a water inlet 21, which is connected to the connecting pipe assembly 3, and the water seepage detection component 2 is provided with a detection cavity 22, which is connected to the water inlet 21, so that the detection liquid can be input into the detection cavity 22 through the connecting pipe assembly 3 and the water inlet 21.

[0065] A first opening 23 is provided at the first end of the water seepage detection member 2 , and a second opening 24 is provided at the second end of the water seepage detection member 2 . The first opening 23 and the second opening 24 are connected through the detection cavity 22 . The first opening 23 and the second opening 24 are used to insert the detection sample 4 .

[0066] It can be understood that by inserting the test sample 4 into the first opening 23 and the second opening 24 respectively, and then inputting the test liquid into the test cavity 22, the test sample 4 is in contact with the test liquid, thereby performing a water seepage test on the test sample 4.

[0067] Since the first opening 23 and the second opening 24 are connected through the detection cavity 22, the two ends of the water seepage detection member 2 are connected, and the detection sample 4 can be inserted into the water seepage detection member 2 from the first opening 23, and the detection sample 4 can be extended out of the water seepage detection member 2 from the second opening 24, so that the middle of the detection sample 4 can be located in the detection cavity 22 of the water seepage detection member 2, thereby performing a T-type water seepage test inside the optical cable on the water seepage detection member 2. When the end of the detection sample 4 is inserted into the first opening 23 and / or the second opening 24, the end water seepage test of the detection sample 4 can be realized.

[0068] That is to say, the present application connects the two ends of the water seepage detection member 2 so that the optical cable water seepage detection device can simultaneously meet the requirements of the optical cable end water seepage test and the optical cable internal T-type water seepage test.

[0069] It should be noted here that the water inlet 21 is arranged in the middle part of the water seepage detection part 2 to ensure that when the test samples 4 are inserted into the two ends of the water seepage detection part 2, the test samples 4 at both ends of the water seepage detection part 2 can be symmetrical about the water inlet 21 to ensure that the water flow conditions and pressures to which the test samples 4 are subjected are the same, thereby reducing the influence of external factors on the test results and ensuring the accuracy and reliability of the test results.

[0070] It should also be noted here that the water seepage detection piece 2 is fixed by a specific test frame, which can ensure that both ends of the water seepage detection piece 2 are flush with the test sample 4 on the sample frame, thereby facilitating the insertion of the test sample 4 into the water seepage detection piece 2.

[0071] Furthermore, if Figures 1 to 3 As shown, a drainage branch 25 is provided at the bottom of the water seepage detection member 2, the drainage branch 25 is connected to the detection cavity 22, and a third control valve 26 is provided on the drainage branch 25 for controlling the connection between the drainage branch 25 and the external environment.

[0072] It is understandable that when the detection liquid is input into the water seepage detection member 2, the third control valve 26 can be opened to connect the detection cavity 22 with the external environment through the drainage branch 25. When the detection liquid continues to flow out of the drainage branch 25, it means that the detection cavity 22 of the water seepage detection member 2 is already full of the detection liquid, and the air in the connecting pipe assembly 3 and the water seepage connector has been exhausted. At this time, the third control valve 26 is disconnected, the drainage branch 25 is disconnected from the external environment, and the optical cable water seepage test is performed. Since there is no air in the detection cavity 22 at this time, the water seepage detection of the optical cable will not be disturbed by the air, which effectively avoids the misjudgment or missed judgment of the optical cable water seepage detection, thereby improving the accuracy and reliability of the optical cable water seepage detection result.

[0073] In one embodiment of the present application, Figure 1 As shown, the first opening 23 and the second opening 24 are both provided with a sealing member 27 , and the sealing member 27 is used to seal and connect the test sample 4 and the first opening 23 and the second opening 24 .

[0074] It can be understood that by arranging the sealing member 27 at the first opening 23 and the second opening 24, and sealing the connection between the test sample 4 and the first opening 23 and the second opening 24 through the sealing member 27, the connection between the test sample 4 and the water seepage detection member 2 is tightly sealed, thereby ensuring that the connection between the test sample 4 and the opening will not leak or seep water, and preventing external air from entering the detection cavity 22 through the sealing member 27, thereby ensuring the accuracy and reliability of the optical cable water seepage detection result.

[0075] Specifically, the sealing member 27 is a sealing rubber plug, which is tightly fitted to the opening to prevent the detection liquid from leaking through the connection and to prevent external air from entering the detection cavity 22 .

[0076] In addition, in order to further improve the sealing performance at both ends of the water seepage detection part 2, a sealing fastening cover 28 can be set at both ends of the water seepage detection part 2. The sealing fastening cover 28 is threadedly connected to the water seepage detection part 2, and the sealing fastening cover 28 abuts against the end of the water seepage detection part 2. The sealing fastening cover 28 and the sealing part 27 cooperate to ensure the sealing connection between the test sample 4 and the water seepage detection part 2.

[0077] And when the water seepage detection member 2 only needs to perform water seepage detection on one test sample 4, the opening where the test sample 4 is not inserted can be sealed by the sealing fastening cover 28, thereby ensuring that the test liquid inside the water seepage detection member 2 cannot leak, thereby avoiding the loss of the test liquid.

[0078] In one embodiment of the present application, Figure 1 As shown, a water inlet 11 is provided at the upper end of the storage box 1 .

[0079] It can be understood that the water injection port 11 is used to fill the interior of the storage box 1 with the test liquid. After the test sample 4 is installed on the water seepage detection member 2, when a water seepage test is required, the test liquid can be filled into the interior of the storage box 1 through the water injection port 11 to adjust the liquid level of the test liquid inside the storage box 1, so that the test height of the water seepage performance of the optical cable can be adjusted according to actual needs, and then the water seepage performance of the optical cable under different height environmental conditions can be tested to meet actual test needs.

[0080] Furthermore, in order to reflect the liquid level of the detected liquid in the storage box 1 , a height mark may be engraved on the side wall of the storage box 1 , so as to obtain the real-time liquid level in the storage box 1 .

[0081] In one embodiment of the present application, the storage box 1 is a plastic component, and the water seepage detection member 2 is a plastic component. By preparing the storage box 1 as a plastic component and preparing the water seepage detection member 2 as a plastic component, the entire components of the optical cable water seepage detection device are made of plastic materials. When the storage box 1 stores salt water, and when the water seepage detection member 2 performs salt water seepage detection, the corrosion resistance of the plastic components is utilized to reduce the corrosion of the entire components by the salt water, thereby ensuring the integrity of the entire components and reducing the maintenance cost of the optical cable water seepage detection device.

[0082] The storage box 1 is preferably made of organic glass, so as to facilitate observation of the water level of the detection liquid in the storage box 1. The water seepage detection element 2 can be made of PVC or nylon material.

[0083] In one embodiment of the present application, Figure 4 The schematic diagram of the top view of the parallel water seepage detection element provided in the embodiment of the present application is illustrated as follows: Figure 4 As shown, in order to perform water seepage detection on multiple optical cables at the same time, multiple water seepage detection components 2 can be connected through a connecting pipe 29, and the connecting pipe 29 is connected to the detection cavity 22, so that the multiple water seepage detection components 2 form parallel water seepage detection components.

[0084] Furthermore, when it is necessary to perform water seepage detection on multiple optical cables, the multiple optical cables can be inserted into the openings of the parallel water seepage detection component in sequence, and the connecting pipe assembly 3 is connected to the water inlet 21 of the parallel water seepage detection component, so that the detection liquid is input into the detection cavity 22 of the multiple water seepage detection components 2, so as to realize water seepage detection on multiple optical cables at the same time and improve the detection efficiency.

[0085] Combine the following Figures 1 to 3 A specific embodiment of the optical cable water seepage detection device of the present application is described.

[0086] like Figures 1 to 3As shown, two storage tanks 1 are provided, and salt water is filled into one of the storage tanks 1 to use one of the storage tanks 1 as a salt water tank; pure water is filled into the other storage tank 1 to use the other storage tank 1 as a pure water tank.

[0087] Then, one of the first connecting branches 31 is connected to the salt water tank to use it as a salt water delivery pipe; the other first connecting branch 31 is connected to the pure water tank to use it as a pure water delivery pipe. At the same time, a first first control valve 33 is set in the salt water delivery pipe as a salt water control valve; a second first control valve 33 is set in the pure water delivery pipe as a pure water control valve.

[0088] Then, the first end of the second connecting branch 32 is connected to the salt water delivery tank and the pure water delivery tank through the three-way valve 35, and the second end of the second connecting branch 32 is connected to the water inlet 21 of the water seepage detection member 2. At the same time, a second control valve 34 is set at the second end of the second connecting branch 32 to serve as a control switch for inputting the detection liquid into the water seepage detection member 2.

[0089] At the same time, a drainage branch 25 is provided at the bottom of the water seepage detection member 2, and a third control valve 26 is provided in the drainage branch 25 to control the connection or disconnection of the drainage branch 25 with the external environment through the third control valve 26. A first opening 23 is provided at the first end of the water seepage detection member 2, and a second opening 24 is provided at the second end of the water seepage detection member 2. The first opening 23 and the second opening 24 are connected through the detection cavity 22, so that the two ends of the water seepage detection member 2 are connected. Sealing members 27 and sealing fastening covers 28 are provided at both ends of the water seepage detection member 2, so that the detection sample 4 and the two ends of the water seepage detection member 2 are sealed and connected. Then, the optical cable water seepage detection device is formed by combining the storage box 1, the two first connecting branches 31, the second connecting branch 32 and the water seepage detection member 2.

[0090] When a pure water test is required for the optical cable end, the pure water control valve is closed, pure water is filled into the pure water tank, and the pure water level in the pure water tank is adjusted. Then, the end of the test sample 4 is installed at the end opening of the water seepage detection member 2, and the connection between the test sample 4 and the water seepage detection member 2 is sealed by the sealing member 27 and the sealing fastening cover 28.

[0091] After the installation of the test sample 4 is completed, the pure water control valve is opened, the salt water control valve is closed, and the second control valve 34 and the third control valve 26 are opened at the same time, and the pure water in the pure water tank is input into the detection cavity 22 of the water seepage detection member 2. When pure water continues to flow out of the drainage branch 25, the air in the connecting pipe 29 and the water seepage detection member 2 has been exhausted, and the third control valve 26 is closed at this time.

[0092] Then confirm the liquid level in the pure water tank again. If the liquid level in the pure water tank does not meet the required height for the water seepage test, pure water can be filled into the pure water tank through the water filling port 11 of the pure water tank to ensure the liquid level in the pure water tank. Then, the pure water seepage test can be carried out through the optical cable water seepage detection device.

[0093] After the pure water seepage detection is completed, when it is necessary to switch to the salt water seepage detection, the salt water tank is filled with salt water under the closed state of the salt water control valve, and the salt water level in the salt water tank is adjusted. After the pure water seepage detection is completed, the pure water control valve is closed, and the second control valve 34 and the third control valve 26 are opened to discharge the pure water in the connecting pipe 29 and the seepage detection member 2. The salt water control valve is then opened, and the salt water in the salt water tank is input into the detection cavity 22 of the seepage detection member 2. When salt water continues to flow out of the drainage branch 25, the air in the connecting pipe 29 and the seepage detection member 2 has been exhausted. At this time, the third control valve 26 is closed to complete the switching between pure water and salt water. The liquid level in the salt water tank is then confirmed, and after ensuring that the liquid level in the salt water tank meets the requirements, the salt water seepage detection is performed through the optical cable seepage detection device.

[0094] When a T-type water seepage test is required inside the optical cable, the test sample 4 is inserted into the test cavity 22 from the first opening 23, and the test sample 4 is extended from the second opening 24. The control process of the control valve is the same as the control process of the control valve in the above-mentioned optical cable end water seepage test, which will not be repeated here.
