Description

Technical Field

[0001] The present application relates to the technical field of submarine cable construction, and in particular to a watertightness detection device and a watertightness detection method for a penetration component. Background Art

[0002] During submarine cable construction, penetrations are often used to seal the connection between the submarine cable and the submarine hull as the cable passes through it. These penetrations employ connectors, glue, or mechanical seals to achieve a seal between the penetration and the submarine cable, and between the penetration and the hull.

[0003] Before a penetration is put into use, it must undergo a watertightness test. In related art, this test involves taking a portion of the submarine cable and installing it on the penetration. The cable and penetration are then placed in a watertight tank filled with water. After maintaining the water pressure for a period of time, the tank is removed and inspected for leaks.

[0050] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0052] Prior to commissioning, penetrations must undergo a watertightness test. This test involves installing a portion of the submarine cable onto the penetration. The cable and penetration are then placed in a watertight tank filled with water. After maintaining the water pressure for a period of time, the tank is removed and inspected for leaks.

[0053] However, in actual use, submarine cables, under the influence of seawater pressure, can easily exert tension on the penetrations, significantly impacting the penetrations' watertightness. Consequently, the aforementioned penetration watertightness testing process struggles to simulate the corresponding tensile stress conditions, making it difficult to verify the penetrations' watertightness under these conditions. This results in low reliability.

[0054] Therefore, an embodiment of the present application provides a watertightness detection device and a watertightness detection method for a penetration piece, wherein the watertightness detection device for the penetration piece includes: a detection container, the detection container is used to accommodate the penetration piece and a cable body connected to the penetration piece, a first connecting component, the first connecting component is used to connect the penetration piece; a second connecting component, the second connecting component is used to connect the cable body; a driving component, the driving component connects the first connecting component and the second connecting component, and the driving component is used to drive at least one of the first connecting component and the second connecting component to move relative to the other. Therefore, during testing, the first connecting component and the second connecting component are respectively installed on the penetration component and the cable body, and then the driving component is used to make the second connecting component tend to move away from the first connecting component, so that the cable body generates a pulling force on the penetration component to simulate the tension scenario of the penetration component during actual application; then the penetration component is placed as a whole in the testing container, water is injected into the testing container and pressurized, and the penetration component is taken out after maintaining the pressure to check whether the penetration component is leaking, thereby more accurately detecting the watertight performance of the penetration component under the tension scenario, improving the reliability of the watertight test results, and solving the problem of low reliability of the watertight test results of the penetration component in the prior art.

[0055] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0056] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a watertightness detection device for a cabin penetration component, comprising:

[0057] The detection container 100 is used to accommodate the cabin penetration member 10 and the cable body 20 connected to the cabin penetration member 10.

[0058] A first connecting assembly 200, which is used to connect the cabin penetration member 10;

[0059] A second connecting assembly 300 , the second connecting assembly 300 is used to connect the cable body 20 ;

[0060] The driving assembly 400 is connected to the first connecting assembly 200 and the second connecting assembly 300 . The driving assembly 400 is used to drive at least one of the first connecting assembly 200 and the second connecting assembly 300 to move relative to the other.

[0061] It should be noted that the detection container 100 can be a tank, box, or other container shape, without limitation. During use, the cabin penetration member 10 to be tested and the cable body 20 connected to the cabin penetration member 10 can be placed into the detection container 100, and water or a desired liquid can be added to the detection container 100 as needed, and the detection container 100 can be pressurized.

[0062] The cable body 20 may be a submarine cable, an optical cable, or other types of cables, without limitation. The type of cable may be determined based on the actual scenario to be simulated.

[0063] During the inspection, the first connecting component 200 and the second connecting component 300 are respectively installed on the cabin penetration piece 10 and the cable body 20. Secondly, the driving component 400 is used to make the second connecting component 300 tend to move away from the first connecting component 200 (that is, the first connecting component 200 tends to move away from the second connecting component 300), so that the cable body 20 generates a pulling force on the cabin penetration piece 10 to simulate the tension scenario of the cabin penetration piece 10 during actual application; then the cabin penetration piece 10 is placed as a whole into the inspection container 100, water is injected into the inspection container 100 and pressurized, and the cabin penetration piece 10 is taken out after maintaining the pressure to check whether the cabin penetration piece 10 is leaking, thereby more accurately detecting the watertight performance of the cabin penetration piece 10 under the tension scenario, improving the reliability of the watertightness inspection results, and solving the problem of low reliability of the watertightness inspection results of the cabin penetration piece 10 in the prior art.

[0064] It is additionally noted that, when implementing Figure 1 As shown, a water inlet pipe 110 and a drain pipe 120 can be connected to the detection container 100, and valves can be installed on both the water inlet pipe 110 and the drain pipe 120. The other end of the water inlet pipe 110 is connected to a water reservoir 130. A water pump 140 is also installed on the water inlet pipe 110, allowing pressurized water to be injected into the detection container 100 through the water inlet pipe 110. The other end of the drain pipe 120 is connected to the water reservoir 130. An overflow valve 150 is installed on the drain pipe 120, and a hand valve 160 is installed in the parallel pipe of the overflow valve 150.

[0065] Thus, the overflow valve 150 can release the pressure after the pressure in the detection container 100 reaches a certain value, returning the water to the water reservoir 130, and realizing the recycling of the water source. The manual valve 160 can exhaust the air at the beginning of the water filling of the detection container 100 and release the pressure after the water is drained.

[0066] The test container 100 is also equipped with a pressure transmitter 170 and a pressure gauge 180, both of which are of any model. The pressure transmitter 170 is electrically connected to the water pump 140, transmitting a pressure signal to the water pump 140 via the pressure transmitter 170. This closed-loop feedback loop regulates the operating frequency of the water pump 140, ensuring that the water pressure fluctuates within a certain range. The pressure gauge 180 monitors the pressure within the test container 100 in real time, facilitating smooth watertightness testing.

[0067] In addition, when implementing Figure 1As shown, before the watertightness test, after the cable body 20 is inserted into the cabin penetration member 10 and the two are fastened together, water-testing paste can be applied to the cabin penetration member 10. A sealing cap 11 is then threaded onto the cabin penetration member 10 to seal the water-testing paste within the cabin penetration member 10. The water-testing paste should cover the gap between the cable body 20 and the cabin penetration member 10, meaning one side of the gap is connected to the exterior of the cabin penetration member 10, while the water-testing paste covers the other side. If water leaks through the gap, the water will contact the water-testing paste, causing it to change color. After the watertightness test is completed, the sealing cap 11 can be opened and the color change of the water-testing paste (e.g., from yellow to red) can be observed to determine the watertightness test result of the cabin penetration member 10.

[0068] like Figure 2 As shown, in some embodiments, a head seal 500 is further included. The head seal 500 is used to be sleeved on the end of the cable body 20 away from the cabin penetration piece 10 to seal the end of the cable body 20 away from the cabin penetration piece 10 through the head seal 500.

[0069] The sealing member 500 can be a sealing cap made of rubber or silicone. The sealing cap wraps around the end of the cable body 20. The sealing cap can be fastened to the cable body 20 by means of a clamp lock or heat seal. A waterproof tape is then wrapped around the connection between the sealing cap and the cable body 20 to ensure a tight seal between the two. The sealing member 500 can also be a sealant thickly applied to the end of the cable body 20.

[0070] Thus, the end of the cable body 20 away from the cabin penetration member 10 is sealed by the head seal 500 , thereby reducing the possibility of moisture entering the cabin penetration member 10 from the interior of the cable body 20 .

[0071] In some embodiments, at least one of the first connecting assembly 200 and the second connecting assembly 300 includes at least two clamping members and a plurality of fasteners. The clamping members are used to be distributed on both sides of the cabin penetration member 10 or the cable body 20. The fasteners fasten the clamping members to each other so that the clamping members clamp the cabin penetration member 10 or the cable body 20.

[0072] The clamping member is connected to the driving assembly 400 .

[0073] For example, either the first connection assembly 200 or the second connection assembly 300 may include at least two clamping members and a plurality of fasteners, or both of them may include at least two clamping members and a plurality of fasteners.

[0074] Furthermore, the clamping member includes a clamping plate and a connecting plate, wherein the clamping plate is connected to the connecting plate;

[0075] The fasteners are used to fasten the clamps together so that the clamps clamp the cabin penetration member 10 or the cable body 20;

[0076] The connecting plate is connected to the driving assembly 400 .

[0077] like Figure 2 As shown, in this embodiment, the first connecting assembly 200 includes two first clamping members 210 and a plurality of first fasteners 220, wherein the first fasteners 220 may be screws or bolts. The two first clamping members 210 are located on either side of the cabin penetration member 10. The first clamping members 210 include a first clamping plate 211 and a first connecting plate 212. The first clamping plate 211 may be connected to the first connecting plate 212 by welding, integral molding, or other means. The first connecting plate 212 is located at the end of the first clamping plate 211 facing the second connecting assembly 300. The first clamping plate 211 may be a stepped structure with multiple through-holes defined therein. The first fasteners 220 penetrate through the through-holes of both first clamping plates 211 to fasten the two first clamping plates 211 together, thereby clamping the two first clamping plates 211 to the cabin penetration member 10.

[0078] like Figure 2 and Figure 3 As shown, it is understood that a groove adapted to the outer contour of the cabin penetration member 10 can be provided on the side of the first clamping plate 211 facing the cabin penetration member 10 to ensure that the first clamping plate 211 effectively clamps the cabin penetration member 10. Furthermore, the first connecting plate 212 can be semicircular in shape. When the two first clamping members 210 are fastened together, the two first connecting plates 212 together form a quasi-circular structure. One end of the drive assembly 400 is connected to the first connecting plate 212.

[0079] like Figure 2 As shown, similar to the first connecting assembly 200, the second connecting assembly 300 includes two second clamping members 310 and a plurality of second fasteners 320, wherein the second fasteners 320 may be screws or bolts. The two second clamping members 310 are located on either side of the cable body 20. The second clamping members 310 include a second clamping plate 311 and a second connecting plate 312. The second clamping plate 311 may be connected to the second connecting plate 312 by welding, integral molding, or other means. The second connecting plate 312 is located at the end of the second clamping plate 311 facing the first connecting assembly 200. The second clamping plate 311 may be a stepped structure with multiple through-holes defined therein. The second fasteners 320 penetrate through the through-holes of both second clamping plates 311, thereby fastening the two second clamping plates 311 together via the second fasteners 320, thereby clamping the two second clamping plates 311 to the cable body 20.

[0080] like Figure 2 and Figure 4As shown, it is understandable that a groove that matches the outer contour of the cable body 20 can be provided on the side of the second clamping plate 311 facing the cable body 20 to ensure that the second clamping plate 311 has a better clamping effect on the cable body 20. The inner surface of the groove on the side of the second clamping plate 311 facing the cable body 20 can be roughened, or a cushion layer made of PE material can be placed on the inner surface of the groove to improve the tightness when clamping the cable body 20. In addition, the second connecting plate 312 can be a semicircular structure. When the two second clamping members 310 are fastened together, the two second connecting plates 312 will together form a quasi-circular structure. The other end of the drive assembly 400 is connected to the second connecting plate 312.

[0081] During installation, the two first clamping plates 211 clamp the cabin penetration member 10, and then the first fasteners 220 are installed to clamp the two first clamping plates 211 to the cabin penetration member 10. The two second clamping plates 311 clamp the cable body 20, and then the second fasteners 320 are installed to clamp the two second clamping plates 311 to the cable body 20. Next, the drive assembly 400 is connected to the first connecting plate 212 and the second connecting plate 312. The drive assembly 400 can then control the first connecting assembly 200 and the second connecting assembly 300 to move apart, thereby applying a pulling force on the cable body 20 against the cabin penetration member 10.

[0082] It should be noted that the number of fasteners, the number of splints, and the shapes of the splints and connecting plates can be reasonably set according to actual needs and are not limited thereto.

[0083] like Figure 2 As shown, in some embodiments, the driving assembly 400 includes a plurality of elastic members 410 and adjustment members;

[0084] One end of the elastic member 410 in the extending direction is connected to the first connecting assembly 200;

[0085] The other end of the elastic member 410 in the extending direction is connected to the second connecting assembly 300;

[0086] The adjusting member connects the first connecting assembly 200 and the second connecting assembly 300 , and is used to adjust the distance between the first connecting assembly 200 and the second connecting assembly 300 to adjust the deformation amount of the elastic member 410 .

[0087] The elastic member 410 is capable of elastic deformation, meaning it can rebound after being compressed. Therefore, during installation, after the first connecting assembly 200 is secured to the cabin penetration member 10, the adjustment member can be used to first bring the first and second connecting assemblies 200 and 300 closer together to compress the elastic member 410, and then the second connecting assembly 300 can be secured to the cable body 20. The adjustment member then releases the restraint on either the second connecting assembly 300 or the first connecting assembly 200. This allows the elastic member 410 to cause the second connecting assembly 300 to move away from the first connecting assembly 200 due to its rebound force, thereby exerting a tensile force on the cable body 20 against the cabin penetration member 10.

[0088] like Figure 2 As shown, further, the adjusting member includes a plurality of control screws 420 and a plurality of control nuts 430;

[0089] One end of the control screw 420 in the extending direction is connected to any one of the first connecting assembly 200 and the second connecting assembly 300;

[0090] The other end of the control screw 420 extends through the other one of the first connecting assembly 200 and the second connecting assembly 300 and is correspondingly threadedly connected to the control nut 430 .

[0091] In this embodiment, one end of the control screw 420 in the extending direction is connected to the first connecting component 200 ; the other end of the control screw 420 in the extending direction passes through the second connecting component 300 and is correspondingly threadedly connected to the control nut 430 .

[0092] Specifically, a plurality of circumferentially distributed through-holes are formed in each of the first and second connecting plates 212, 312. A control screw 420 has a head at one end. The end of the control screw 420, away from the head, passes through the first and second connecting plates 212, 312, and is threadedly connected to a control nut 430, such that the head and the control nut 430 respectively abut against opposite side walls of the first and second connecting plates 212, 312.

[0093] The elastic member 410 is a spring, and both ends of the spring in the extension direction are respectively connected to the first connecting component 200 and the second connecting component 300;

[0094] Each spring corresponds to each control screw 420 one by one, and the spring is coaxially sleeved on the control screw 420.

[0095] It should be noted that the two ends of the springs respectively abut the opposing side walls of the first connecting plate 212 and the second connecting plate 312. The number of springs is the same as the number of control screws 420, and each spring is coaxially sleeved on a corresponding control screw 420, so that the control screw 420 provides support for the springs, reducing the possibility of the springs being weakened due to bending.

[0096] Therefore, after the first connecting assembly 200 is fastened to the cabin penetration member 10, the control nut 430 can be tightened to compress the spring, and then the second connecting assembly 300 can be fastened to the cable body 20. Subsequently, the control nut 430 is loosened, allowing the spring's rebound force to gradually act on the cable body 20, thereby exerting a tensile force on the cabin penetration member 10. During this process, the degree of tightening or loosening of the control nut 430 can be adjusted according to actual needs to regulate the tension on the cable body 20, facilitating adaptation to various stress scenarios during watertightness testing.

[0097] In other embodiments, one end of the control screw 420 can be connected to the second connecting assembly 300; the other end of the control screw 420 can pass through the first connecting assembly 200 and be threadedly connected to the control nut 430. The elastic member 410 can also be an elastic block or elastic sheet, and the adjusting member can also be a pneumatic cylinder or a hydraulic cylinder.

[0098] like Figure 2 As shown, the control screw 420 is further threadedly connected to a limit nut 440, which is located on the side of the control nut 430 facing away from the first connecting assembly 200. The limit nut 440 can limit the range of motion of the control nut 430 and the second connecting plate 312, reducing the possibility of the two being separated from the control screw 420, thereby ensuring safety during operation.

[0099] like Figure 2 As shown, in some embodiments, a scale member 600 and an indicator member 700 are further included, and the distribution direction of the scale on the scale member 600 is parallel to the extension direction of the elastic member 410;

[0100] The scale member 600 is provided on any one of the first connecting assembly 200 and the second connecting assembly 300;

[0101] The indicator 700 is provided on the other of the first connecting assembly 200 and the second connecting assembly 300 , and the indicator 700 is used to indicate the scale on the scale member 600 .

[0102] It should be noted that the scale member 600 can be provided on the first connecting component 200 and the indicator member 700 can be provided on the second connecting component 300. The scale member 600 can also be provided on the second connecting component 300 and the indicator member 700 can be provided on the first connecting component 200.

[0103] In this embodiment, the scale member 600 may be a scale with graduations thereon, and of course, the scale member 600 may also be a rod, a strip, or a grating ruler. The indicator 700 may be a pointer, a thin rod, or other shapes.

[0104] Support posts 800 can be mounted on both the first connecting plate 212 and the second connecting plate 312 by screwing, bonding, or other means. The scale member 600 is screwed, bonded, or otherwise connected to the support posts 800 on the first connecting plate 212, with the extension direction of the scale member 600 aligning with the extension direction of the elastic member 410. The indicator member 700 is screwed, bonded, or otherwise connected to the support posts 800 on the second connecting plate 312, with the indicator member 700 pointing to the scale on the scale member 600.

[0105] Therefore, during the compression or rebound process of the spring, the change in the scale indicated by the indicator 700 can reflect the deformation of the spring, and further reflect the magnitude of the pulling force applied to the cable body 20 .

[0106] In some embodiments, the principle of a "sliding rheostat" can optionally be employed to convert the displacement of the second connecting assembly 300 into a precise electrical signal. For example, the scale member 600 and the indicator member 700 are configured as conductors and connected to a circuit equipped with a battery and an ammeter. This allows the real-time displacement of the second connecting assembly 300 to be accurately converted into an electrical signal. The change in the pointer on the ammeter then reflects the deformation of the spring, and thus the magnitude of the tension applied to the cable body 20.

[0107] In summary, the embodiment of the present application provides a watertight detection device for a piercing piece. During detection, the first connecting component 200 and the second connecting component 300 are respectively installed on the piercing piece 10 and the cable body 20. Secondly, the driving component 400 is used to make the second connecting component 300 tend to move away from the first connecting component 200, so that the cable body 20 generates a pulling force on the piercing piece 10, so as to simulate the tension scenario of the piercing piece 10 during actual application; then the piercing piece 10 is placed as a whole into the detection container 100, water is injected into the detection container 100 and pressurized, and the piercing piece 10 is taken out after maintaining the pressure to check whether the piercing piece 10 is leaking, thereby more accurately detecting the watertight performance of the piercing piece 10 under the tension scenario, improving the reliability of the watertight detection results, and solving the problem of low reliability of the watertight detection results of the piercing piece 10 in the prior art.

[0108] An embodiment of the present application provides a method for detecting watertightness of a cabin penetration member, using the cabin penetration member watertightness detection device of any of the above embodiments, including the following steps:

[0109] The first connecting assembly 200 of the watertightness detection device of the cabin penetration member is connected to the cabin penetration member 10, and the second connecting assembly 300 of the watertightness detection device of the cabin penetration member is connected to the cable body 20. At the same time, the driving assembly 400 of the watertightness detection device of the cabin penetration member drives the first connecting assembly 200 and the second connecting assembly 300 away from each other, so as to apply a pulling force on the cabin penetration member 10 to the cable body 20;

[0110] Place the whole formed by the penetration piece 10 and the cable body 20 into the inspection container 100 in the watertight detection device of the penetration piece, and at the same time fill water into the inspection container 100 and pressurize it. After maintaining the pressure, take out the penetration piece 10 to check whether the penetration piece 10 is leaking; wherein, the whole formed by the penetration piece 10 and the cable body 20 refers to the whole formed by the penetration piece 10, the cable body 20, the first connecting component 200, the second connecting component 300 and the driving component 400.

[0111] Specifically, after the first connecting assembly 200 is fastened to the cabin penetration member 10, the control nut 430 is tightened to compress the spring, and then the second connecting assembly 300 is fastened to the cable body 20. Subsequently, the control nut 430 is loosened, allowing the spring's rebound force to gradually act on the cable body 20, thereby exerting a pulling force on the cabin penetration member 10 on the cable body 20.

[0112] Before and after the watertightness test of the cabin penetration piece 10, the insulation resistance of the cabin penetration piece 10 is measured using a test voltage of 1 kV and the data is recorded. This makes it easier to determine whether the watertightness test has affected the insulation performance of the cabin penetration piece 10.

[0113] Before the watertightness test, a water-testing paste can be applied to the interior of the penetration member 10. A sealing cap 11 can be threaded onto the penetration member 10 to seal the water-testing paste within the penetration member 10. The water-testing paste should cover the gap between the cable body 20 and the penetration member 10. This means that one side of the gap connects to the exterior of the penetration member 10, while the other side of the gap is covered by the water-testing paste. If water leaks through the gap, the water will contact the water-testing paste, causing it to change color. After the watertightness test, the sealing cap 11 can be opened and the color change of the water-testing paste (e.g., from yellow to red) can be observed to determine the watertightness test result of the penetration member 10.

[0114] During the watertightness test, the pressure value of the overflow valve 150 can be set, the manual valve 160 can be opened, and the water pump 140 can be started to gradually fill the test container 100 with water and exhaust the air. After the exhaust is completed, the manual valve 160 can be closed. After the test is completed, the water pump 140 is turned off and the manual valve 160 is opened to release the pressure.

[0115] In some embodiments, for example, the watertightness test may involve applying a tensile force of 1 ton to the cable body 20, maintaining an internal pressure of 20 MPa within the container 100 for 48 hours, and verifying the watertightness of the penetration 10. A spring with an elastic modulus of 100 N / mm may be used, and the compression distance of each spring is: L = F / 8 / k = 1*9.8*1000 / 8 / 100 = 12.25 mm.

[0116] At the same time, the pressure signal of the pressure transmitter 170 is converted into an electrical signal, and the pressure signal is used to control the rotation speed of the water pump 140. If the internal pressure of the detection container 100 is ≤16MPa, the water pump 140 operates at full frequency; if the internal pressure of the detection container 100 is between 16 and 20MPa, the water pump 140 operates at half the frequency; if the internal pressure of the detection container 100 is ≥20MPa, the water pump 140 stops operating.
