Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Referring to fig. 1, there is shown one of schematic diagrams of a system for detecting interference of a submarine cable with a submarine pipeline according to an embodiment of the present application; referring to fig. 2, a second schematic diagram of a system for detecting interference of an ocean bottom cable on an ocean bottom pipeline according to an embodiment of the present application is shown; referring to fig. 3, there is shown one of the schematic diagrams of an angle between a submarine cable and a submarine pipeline according to the embodiments of the present application; referring to fig. 4, a second schematic diagram of an angle between a submarine cable and a submarine pipeline according to an embodiment of the present application is shown. As shown in fig. 1 to 4, the system for detecting the interference of the submarine cable 20 with the submarine pipeline 10 comprises: a subsea pipeline 10, a subsea cable 20, an analog cell 30, a power supply 40, a signal amplification device 50, and a detection device 60.
The simulation tank 30 stores a solution, the submarine pipeline 10 is located in the simulation tank 30, the submarine pipeline 10 is located below the liquid level of the solution, two ends of the submarine pipeline 10 are respectively electrically connected with the signal amplification device 50, the signal amplification device 50 is used for amplifying the voltage on the submarine pipeline 10, and the detection device 60 is used for detecting the voltage signal on the signal amplification device 50. The power source 40 is electrically connected to the submarine cable 20, and the submarine cable 20 is located in the simulation basin 30, and the submarine cable 20 is at a first predetermined distance from the submarine pipeline 10, and the submarine cable 20 is at a predetermined angle from the submarine pipeline 10.
In the embodiment of the present application, since the submarine pipeline 10 is located below the liquid level of the solution in the simulation tank 30, it corresponds to a case where the simulated submarine pipeline 10 is located on the seabed. In addition, since the submarine pipeline 10 and the submarine cable 20 are located in the simulation pond 30, there is a first preset distance between the submarine cable 20 and the submarine pipeline 10. The submarine cable 20 is at a predetermined angle to the submarine pipeline 10, and the submarine cable 20 is electrically connected to the power source 40, so that, when the power source 40 supplies power to the submarine cable 20, current flows through the submarine cable 20, and the submarine cable 20 affects the submarine pipeline 10 to provide a voltage on the submarine pipeline 10. Since both ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50, respectively, after a voltage is generated on the submarine pipeline 10, the voltage on the submarine pipeline 10 can be transmitted to the signal amplification device 50, and the signal amplification device 50 can amplify the voltage on the submarine pipeline 10, so that the detection device 60 can detect the voltage amplified by the signal amplification device 50 on the submarine pipeline 10, and thus, the voltage on the submarine pipeline 10 can be detected conveniently. That is, in the embodiment of the present application, the power source 40 is electrically connected to the submarine cable 20, and the two ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50, respectively, so that when the submarine cable 20 has a weak voltage on the submarine pipeline 10 after being powered on, the signal amplification device 50 can amplify the voltage on the submarine pipeline 10, so that the detection device 60 can detect the amplified voltage, and thus can determine the voltage on the submarine pipeline 10, and further can determine the influence relationship of the submarine cable 20 on the voltage on the submarine pipeline 10, and can determine how to lay the submarine pipeline 10 and deploy the submarine cable 20.
It should be noted that, in the embodiment of the present application, the detecting device 60 may be a multimeter, and of course, the detecting device 60 may also be other devices capable of detecting voltage, for example, the detecting device 60 may also be a voltmeter, and the embodiment of the present application is not limited herein as to the specific type of the detecting device 60. Wherein, when the detection device 60 is a multimeter, at this moment, the detection device 60 may further include a test box, the signal amplification device 50 is connected to the test box, and the voltage on the test box is detected through the multimeter, so as to detect the voltage of the signal amplification device 50.
In addition, the signal amplifying device 50 may be an amplifier, and in this case, the amplifier has functions of filtering and amplifying, so as to prevent the voltage from being interfered by the solution during the transmission process. The amplification factor of the amplifier can be set according to actual needs, for example, the amplification factor of the amplifier is 100, and in this case, if the voltage on the submarine pipeline 10 is 0.05V, the voltage after amplification by the signal amplification device 50 is 5V, so that the voltage after amplification can be conveniently detected by the detection device 60. For another example, the amplification factor of the amplifier is 200, and in this case, if the voltage on the submarine pipeline 10 is 0.05V, the voltage after amplification by the signal amplification device 50 is 10V, so that the voltage after amplification can be easily detected by the detection device 60. The embodiment of the present application is not limited herein with respect to the specific amplification factor of the amplifier.
In addition, after the amplification of the amplifier is determined, the voltage on the subsea pipeline 10 can be deduced back by the amplification. For example, if the voltage detected by the detection device 60 is 5V and the amplification factor of the amplifier is 100, the voltage on the subsea pipeline 10 can be inversely estimated to be 0.05V.
In addition, in the embodiment of the present application, the first preset distance between the submarine pipeline 10 and the submarine cable 20 may be set according to actual needs, for example, the first preset distance may be 0.3 meter, may also be 0.5 meter, and may also be 1 meter, and the specific value of the first preset distance is not limited herein. In addition, the preset included angle between the submarine cable 20 and the submarine pipeline 10 may also be set according to actual needs, for example, the preset included angle may be 30 degrees, may also be 60 degrees, and may also be 90 degrees, and for a specific value of the preset included angle, the embodiment of the present application is not limited herein. The preset included angle between the submarine cable 20 and the submarine pipeline 10 is an included angle between the submarine cable 20 and the central axis of the submarine pipeline 10, and the included angle between the submarine cable 20 and the central axis of the submarine pipeline 10 is clockwise. For example, as shown in fig. 3, the preset angle between the submarine pipeline 10 and the submarine cable 20 is α.
In addition, in the embodiment of the present application, the power source 40 may be a three-phase current generating device, and in this case, after the power source 40 is electrically connected to the submarine cable 20, the current in the submarine cable 20 may be large, for example, the current in the submarine cable 20 may be 75A, so that the current in the submarine cable 20 is almost identical to the current in the submarine cable 20 in practice. Of course, the power source 40 may also be other devices, for example, the power source 40 may also be a battery, to which the submarine cable 20 is connected. The specific type of the power source 40 is not limited herein.
In addition, in the present embodiment, after the power source 40 is electrically connected to the submarine cable 20, an alternating current is supplied to the submarine cable 20. The submarine cable 20 may be connected to the power source 40 through a connection line, and both ends of the submarine cable 20 may be located above the liquid level of the solution, and the portions of the submarine cable 20 other than both ends are located in the solution, at this time, when the submarine cable 20 is connected to the power source 40 through the connection line, both ends of the submarine cable 20 may not be subjected to the waterproofing treatment, and of course, both ends of the submarine cable 20 may also be subjected to the waterproofing treatment. In addition, in the embodiment of the present application, the submarine cable 20 may also be completely located in the solution, and at this time, both ends of the submarine cable 20 may be subjected to waterproof treatment, so as to avoid the problem that both ends of the submarine cable 20 leak electricity in the solution after both ends of the submarine cable 20 are connected to the power supply 40 through the connection line.
Additionally, in the present embodiment, the solution may be seawater.
When the solution is seawater, this time, it is equivalent to seawater in the simulation tank 30, so that the simulation tank 30 can be closer to the actual seabed environment, and the voltage detection for the subsea pipeline 10 is closer to the actual voltage on the subsea pipeline, so that the voltage detected for the subsea pipeline 10 has a more guiding significance to the reality.
The solution may be other liquids, for example, the solution may be fresh water, or a liquid obtained by adding sodium chloride to fresh water. The examples of the present application are not limited herein with respect to the particular type of solution.
In addition, in the embodiment of the present application, the simulation cell 30 may be a water pool with a depth of 8 meters by 6 meters, and of course, the simulation cell 30 may be a water pool with another volume, for example, the simulation cell 30 may have a size of 5 meters by 5 meters and a depth of 6 meters. The size of the simulation pool 30 is not limited in the embodiments of the present application.
Additionally, in some embodiments, the length of the subsea conduit 10 may be less than or equal to 5 meters.
When the length of the submarine pipeline 10 is less than or equal to 5 meters, the length of the submarine pipeline 10 in the embodiment of the present application is smaller than that of a pipeline actually laid in the seabed, which is equivalent to that by performing analog detection on the submarine pipeline 10 having a smaller length, the accuracy of detection can be made higher, and thus, a better guidance effect can be provided for the pipeline actually laid in the seabed. In addition, the length of the submarine pipeline 10 is less than or equal to 5 meters, and the length of the submarine pipeline 10 is small, so that the submarine pipeline 10 can be conveniently carried.
Of course, the length of the subsea pipeline 10 may also be greater than 5 meters, for example, the length of the subsea pipeline 10 may also be 6 meters, and may also be 7 meters, and the specific length of the subsea pipeline 10 is not limited herein.
In addition, in some embodiments, the signal amplifying device 50 may be connected with a detection line, and the detection line is at least partially located above the liquid level of the solution, and the detection device 60 is configured to detect a voltage signal on the detection line to detect the voltage signal on the signal amplifying device 50.
When the signal amplifying device 50 is connected to a detection line, in this case, when the submarine cable 20 is powered on so that a voltage is applied to the submarine pipeline 10, the voltage applied to the submarine pipeline 10 may be transmitted to the signal amplifying device 50, and the signal amplifying device 50 may amplify the voltage so that the amplified voltage is transmitted to the detection line, so that the voltage is transmitted to the detection line at the detection line, so that the voltage amplified by the signal amplifying device 50 may be determined by detecting the voltage applied to the detection line. That is, by connecting the signal amplification device 50 to the detection line, at least a portion of the detection line is located above the liquid level of the solution, so that the voltage signal on the detection line can be detected by the detection device 60, thereby determining the voltage signal on the signal amplification device 50. In addition, at least part of the detection lines are located above the liquid level of the solution, so that when the detection device 60 detects the voltage on the signal amplification device 50, the voltage on the detection lines located above the liquid level can be directly detected, and the detection points of the detection lines are prevented from being subjected to waterproof treatment when located below the liquid level, that is, the detection device 60 can be used for conveniently detecting the voltage on the signal amplification device 50.
In addition, in some embodiments, both ends of the subsea pipeline 10 may be electrically connected to the signal amplification device 50 through signal lines.
When both ends of the submarine pipeline 10 are electrically connected to the signal amplification apparatus 50 through signal lines, one end of the signal line may be connected to the signal amplification apparatus 50, and the other end of the signal line may be connected to the submarine pipeline 10, so that when a voltage is present on the submarine pipeline 10, the voltage of the submarine pipeline 10 may be transmitted to the signal amplification apparatus 50 through the signal lines, so that the signal amplification apparatus 50 acquires the voltage on the submarine pipeline 10. In addition, after the two ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50 through signal lines, it is possible to prevent the signal amplification device 50 from being directly connected to the submarine pipeline 10, thereby making it difficult to electrically connect the two ends of the submarine pipeline 10 to the signal amplification device 50. That is, by electrically connecting both ends of the submarine pipeline 10 to the signal amplification apparatus 50 through signal lines, it is possible to facilitate the electrical connection of the signal amplification apparatus 50 to the submarine pipeline 10.
It should be noted that one end of the signal line may be welded to both ends of the submarine pipeline 10 through thermite welding, that is, one end of the signal line may be welded to the submarine pipeline 10, and the other end of the signal line may be connected to the signal amplification device 50 through a wire connection, so that both ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50 through the signal line.
In addition, since the voltage is generated on the subsea pipeline 10, the voltage signal is influenced by the distance when the subsea pipeline 10 transmits the voltage to the signal amplifying device 50, that is, the distance between the subsea pipeline 10 and the signal amplifying device 50, and the larger the distance between the subsea pipeline 10 and the signal amplifying device 50, the larger the voltage signal is influenced. To avoid this problem, in some embodiments, the signal amplification device 50 is close to the subsea pipeline 10, and the signal amplification device 50 may have a second predetermined distance from the subsea pipeline 10.
When the signal amplifying device 50 is close to the submarine pipeline 10 and the signal amplifying device 50 is a second predetermined distance from the submarine pipeline 10, at this time, the distance between the signal amplifying device 50 and the submarine pipeline 10 is relatively small, so that after a voltage is generated on the submarine pipeline 10, when the submarine pipeline 10 transmits the voltage to the signal amplifying device 50, the voltage signal can be less affected by the distance between the submarine pipeline 10 and the signal amplifying device 50, so that the voltage signal can be better transmitted to the signal amplifying device 50, and the signal amplifying device 50 can acquire a better voltage signal for amplification, so that the voltage detected by the detecting device 60 is more accurate. That is, when the distance between the submarine pipeline 10 and the signal amplifying device 50 is the second preset distance, at this time, the accuracy of voltage detection with respect to the submarine pipeline 10 can be improved.
It should be noted that the second preset distance may be set according to actual needs, for example, the second preset distance may be 0.3 meter, and may also be 0.5 meter, and for a specific value of the second preset distance, the embodiment of the present application is not limited herein.
Additionally, in some embodiments, the detection system may further comprise a support. A support is located in the simulation basin 30 and the subsea pipeline 10 is located on the support.
When the subsea pipeline 10 is on the support, it is now avoided that the subsea pipeline 10 is in direct contact with the bottom of the simulation basin 30. In addition, after the submarine pipeline 10 is placed on the support, at this time, the position of the submarine cable 20 can be adjusted so that the submarine cable 20 can be located at different positions of the submarine pipeline 10 and the submarine cable 20 can be located at the bottom of the submarine pipeline 10, thereby avoiding the problem that the submarine cable 20 cannot be located at the bottom of the submarine pipeline 10 after the submarine pipeline 10 is in contact with the bottom of the simulation pond 30. That is, by providing the bracket, the submarine pipeline 10 can be spaced from the bottom of the simulation pool 30, so that the position of the submarine cable 20 can be adjusted, the submarine cable 20 can be located at different positions of the submarine pipeline 10, and the simulation of the influence of the submarine cable 20 on the submarine pipeline 10 is closer to the actual situation of the submarine cable 20 on the submarine pipeline.
It should be noted that after the submarine pipeline 10 is placed on the rack, the submarine cable 20 may be partially passed through the rack and thus positioned at the bottom of the submarine pipeline 10.
Additionally, in some embodiments, the detection system may further comprise a waterproof box. The signal amplification device 50 is located in a waterproof box.
When the signal amplification device 50 is located in the waterproof box, the waterproof box can protect the signal amplification device 50, and the solution in the analog pool 30 is prevented from affecting the performance of the signal amplification device 50.
The waterproof box may be made of plastic, or may be made of other waterproof materials, such as alloy, for example, and the embodiments of the present invention are not limited herein.
Additionally, in some embodiments, the detection system may further include a reference electrode 70. A reference electrode 70 is located in the simulation cell 30, and the reference electrode 70 is electrically connected to the signal amplification device 50.
When the reference electrode 70 is located in the analog cell 30 and the reference electrode 70 is electrically connected to the signal amplification device 50, the reference electrode 70 is equivalent to providing a zero potential, i.e. a reference potential, so that when the voltage on the signal amplification device 50 is detected by the detection device 60, the detection device 60 is equivalent to having a detection reference point, thereby facilitating the detection device 60 to determine the voltage on the signal amplification device 50 and thus the voltage on the subsea pipeline 10.
In addition, when the subsea pipeline 10 is in solution in the simulation cell 30, the solution may corrode the subsea pipeline 10 at this time, i.e., the subsea pipeline 10 is electrochemically corroded by the solution in the solution, thereby affecting the performance of the subsea pipeline 10. To avoid this problem, in some embodiments, the detection system may further include a cathodic protection structure 80. A cathodic protection structure 80 is located in the simulation cell 30, and the cathodic protection structure 80 is electrically connected to the subsea pipeline 10.
When the cathodic protection structure 80 is electrically connected to the subsea pipeline 10, where the subsea pipeline 10 is protected from the cathode, the cathodic protection structure 80 acts as an anode, thereby protecting the cathode, which is equivalent to a sacrificial anode, in the solution, i.e. when the solution electrochemically corrodes the subsea pipeline 10, the cathodic protection structure 80 can transfer electrons to the surface of the subsea pipeline 10, thereby causing the cathodic protection structure 80 to be corroded by the solution, avoiding the solution from corroding the subsea pipeline 10. In addition, the cathode protection structure 80 is connected to the submarine pipeline 10, so that the submarine pipeline 10 is closer to the environment of the pipeline actually laid in the seabed in the simulation pool 30, and the data obtained by detecting the submarine pipeline 10 in the simulation pool 30 is more meaningful to the reality.
It should be noted that, in the embodiment of the present application, the cathode protection structure 80 may be a zinc block, but may also be another metal block, and the embodiment of the present application is not limited herein.
The following description will be made with reference to fig. 1 and 2 for the operation of the system for detecting the disturbance of the submarine cable 20 on the submarine pipeline 10 according to the embodiment of the present application:
in using the system for detecting the interference of the submarine cable 20 on the submarine pipeline 10 according to the embodiment of the present invention, the submarine pipeline 10 may be placed in the simulation tank 30, the submarine pipeline 10 is connected to the signal amplification device 50, the signal amplification device 50 is connected to the reference electrode 70, and then the submarine cable 20 is connected to the power supply 40. Then the power supply 40 is activated so that the power supply 40 supplies power to the submarine cable 20, and then the position between the submarine cable 20 and the submarine pipeline 10 and the angle between the submarine cable 10 are adjusted, i.e. the position of the submarine cable 20 is adjusted so that the submarine cable 20 is located at different positions of the submarine pipeline 10 and the angle between the submarine cable 20 and the submarine pipeline 10 is changed, and the voltage signal of the signal amplifying device 50 is detected by the detecting device 60 once every time the position of the submarine cable 20 is adjusted.
For example, by adjusting the angle between the submarine cable 20 and the submarine pipeline 10 to 30 degrees and the distance between the submarine cable 20 and the submarine pipeline 10 to 0.3 meter, the voltage on the signal amplification device 50 in this case is detected by the detection device 60. Then, the angle between the submarine cable 20 and the submarine pipeline 10 is adjusted to 60 degrees, and the distance between the submarine cable 20 and the submarine pipeline 10 is 0.3 meter, and the voltage on the signal amplifying device 50 is detected by the detecting device 60. By analogy, each time the position of the submarine cable 20 is adjusted, the voltage on the signal amplifying device 50 on one side can be detected by the detecting device 60, so that different voltages can be obtained when the submarine cable 20 is located at different positions of the submarine pipeline 10, and further, according to the obtained values, where the submarine cable 20 is located in the submarine pipeline 10 can be determined, and the influence of the submarine cable 20 on the submarine pipeline 10 is small, so that the submarine cable 20 and the specific position of the submarine pipeline 10 where the submarine cable 20 is deployed can be guided in practice when the pipeline is laid in the seabed.
In the embodiment of the present application, since the submarine pipeline 10 is located below the liquid level of the solution in the simulation tank 30, it corresponds to a case where the simulated submarine pipeline 10 is located on the seabed. In addition, since the submarine pipeline 10 and the submarine cable 20 are located in the simulation pond 30, there is a first preset distance between the submarine cable 20 and the submarine pipeline 10. The submarine cable 20 is at a predetermined angle to the submarine pipeline 10, and the submarine cable 20 is electrically connected to the power source 40, so that, when the power source 40 supplies power to the submarine cable 20, current flows through the submarine cable 20, and the submarine cable 20 affects the submarine pipeline 10 to provide a voltage on the submarine pipeline 10. Since both ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50, respectively, after a voltage is generated on the submarine pipeline 10, the voltage on the submarine pipeline 10 can be transmitted to the signal amplification device 50, and the signal amplification device 50 can amplify the voltage on the submarine pipeline 10, so that the detection device 60 can detect the voltage amplified by the signal amplification device 50 on the submarine pipeline 10, and thus, the voltage on the submarine pipeline 10 can be detected conveniently. That is, in the embodiment of the present application, the power source 40 is electrically connected to the submarine cable 20, and the two ends of the submarine pipeline 10 are electrically connected to the signal amplification device 50, respectively, so that when the submarine cable 20 has a weak voltage on the submarine pipeline 10 after being powered on, the signal amplification device 50 can amplify the voltage on the submarine pipeline 10, so that the detection device 60 can detect the amplified voltage, and thus can determine the voltage on the submarine pipeline 10, and further can determine the influence relationship of the submarine cable 20 on the voltage on the submarine pipeline 10, and can determine how to lay the submarine pipeline 10 and deploy the submarine cable 20.
