Description

Technical Field

[0001] The present application relates to the technical field of submarine cable protection device release, and in particular to a submarine cable protection device and method. Background Art

[0002] With the continuous development of the marine economy, the development of marine resources has become a crucial component in supporting this growth. Currently, marine resource development often involves laying cables (also known as cables) on the seabed. Submarine cables serve as critical infrastructure for information and power transmission at sea. However, factors such as the complex seabed geology, current erosion, and marine biological activity can easily expose submarine cables, exposing them to risks such as wear and damage, seriously impacting their normal operation. To protect submarine cables, protective devices such as cement strips are used to effectively shield them.

[0003] In the prior art, the deployment of protective devices often relies on the collaboration of divers and a lifting assembly. Specifically, after the ship is positioned at the submarine cable, the diver visually inspects the correct alignment of the protective device and the cable. Returning to the surface, the diver communicates with the captain to adjust the alignment to ensure the device is properly aligned. Once the protective device and cable are properly aligned, the onboard operator is notified to lower the lifting assembly, which then deploys the protective device over the cable.

[0004] However, this deployment method has the following drawbacks: First, divers typically float to the side of the protective device, primarily observing changes in the height between the device and the cable. However, it is difficult for divers to accurately determine whether the two devices are aligned correctly, resulting in low horizontal alignment accuracy between the device and the cable. Second, relying on divers to determine orientation carries significant operational risks, lacks a high degree of intelligence, and is prone to human visual errors, hindering the accuracy and safety of deployment.

[0050] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0051] See Figure 1 and Figure 2 As shown, a submarine cable protection device deployment system 100 provided in one embodiment of the present application includes a carrying device 110, an attitude adjustment component 120, a sonar component 130, and a computing module 140. The carrying device 110 can be, but is not limited to, a cargo ship, a ship, or a carrying platform, and is not limited here.

[0052] The posture adjustment assembly 120 is connected to the carrier 110. It is used to drive the submarine cable protection device 200 to move, allowing the horizontal posture of the submarine cable protection device 200 relative to the submarine cable 300 to be adjusted. The sonar assembly 130 is connected to the carrier 110. It is used to obtain the position information of the submarine cable protection device 200 relative to the submarine cable 300.

[0053] The computing module 140 is in communication with the sonar assembly 130 and the attitude adjustment assembly 120. The computing module 140 is also configured to receive position information and drive the attitude adjustment assembly 120 based on the position information, so that the attitude adjustment assembly 120 causes the submarine cable protection device 200 to adjust its horizontal attitude so that the submarine cable protection device 200 can be arranged parallel to the submarine cable 300.

[0054] The above-mentioned submarine cable protection device deployment system 100 can be applied to implement a method for deploying a submarine cable protection device 200 .

[0055] Specifically, if Figure 3 As shown, the method for deploying the submarine cable protection device 200 includes:

[0056] S100: Acquire position information of the submarine cable protection device 200 relative to the submarine cable 300.

[0057] Specifically, generally, the distance between the carrying device 110 and the submarine cable 300 can be within the communication range of the sonar component 130. Based on this, when the carrying device 110 is near the submarine cable 300, the position information of the submarine cable protection device 200 relative to the submarine cable 300 can be obtained through the sonar component 130, and then the relative position between the submarine cable 300 and the submarine cable protection device 200 can be obtained.

[0058] S200: Acquire a horizontal deviation parameter between the submarine cable 300 and the submarine cable protection device 200 according to the position information.

[0059] It should be noted that the horizontal deviation parameter may refer to a deviation parameter on the horizontal plane, including but not limited to any one or any combination of length spacing deviation, width spacing deviation and horizontal angle deviation, which can be selected according to different implementation scenarios.

[0060] Based on this, the horizontal deviation parameter can provide feedback on whether the submarine cable 300 and the submarine cable protection device 200 are accurately aligned on the horizontal plane.

[0061] S300, driving the posture adjustment component 120 according to the horizontal deviation parameter, so that the posture adjustment component 120 drives the submarine cable protection device 200 to move, so as to adjust the horizontal posture of the submarine cable protection device 200 so that the submarine cable protection device 200 can be arranged parallel to the submarine cable 300.

[0062] It can be understood that after driving the posture adjustment parameters according to the horizontal deviation parameters, the posture adjustment component 120 can drive the submarine cable protection device 200 to move to a position where it can be set parallel to the submarine cable 300, thereby achieving accurate alignment of the submarine cable protection device 200 and the submarine cable 300.

[0063] In this way, unlike a diver observing the side of the submarine cable protection device 200 in the water to determine whether the submarine cable protection device 200 and the submarine cable 300 are accurately aligned horizontally, the setting of the sonar component 130 can provide feedback on whether the submarine cable 300 and the submarine cable protection device 200 are accurately aligned horizontally, so that the posture adjustment component 120 is driven to adjust the position of the submarine cable protection device 200 according to the position information, which can avoid errors during human eye observation and improve the accuracy of the alignment judgment of the submarine cable protection device 200 and the submarine cable 300, thereby achieving accurate alignment between the submarine cable 300 and the submarine cable protection device 200, ensuring that the submarine cable protection device 200 can form good coverage protection for the submarine cable 300, and then improving the stability and safety of the use of the submarine cable 300; at the same time, it also improves the intelligence and safety of the deployment of the submarine cable protection device 200.

[0064] Further, in some embodiments, Figure 1 and Figure 2 The posture adjustment assembly 120 includes a telescopic arm assembly 121, which is used to drive the submarine cable protection device 200 to extend and retract. The computing module 140 is in communication with the telescopic arm assembly 121 and is used to drive the telescopic arm assembly 121 based on the position information to drive the submarine cable protection device 200 to extend and retract in a direction toward or away from the submarine cable 300, thereby adjusting the horizontal spacing between the submarine cable protection device 200 and the submarine cable 300.

[0065] Specifically, the horizontal deviation parameter includes a width deviation parameter. The width deviation parameter is positively correlated with the shortest distance between the submarine cable protection device 200 and the submarine cable 300 in a direction perpendicular to the submarine cable 300. Figure 4 As shown, the above step S300 may include:

[0066] S310. Drive the telescopic arm assembly 121 according to the width deviation parameter, so that the telescopic arm assembly 121 drives the submarine cable protection device 200 to extend and retract along the length direction perpendicular to the submarine cable 300, so that the submarine cable protection device 200 can cover the submarine cable 300.

[0067] In this way, the relative horizontal distance between the submarine cable protection device 200 and the submarine cable 300 can be adjusted by the telescopic arm assembly 121, thereby driving the horizontal alignment between the submarine cable protection device 200 and the submarine cable 300 without adjusting the position of the carrying device 110, thereby improving the controllability of the horizontal alignment adjustment of the submarine cable protection device 200 relative to the submarine cable 300, and then improving the alignment accuracy of the submarine cable protection device 200 and the submarine cable 300.

[0068] In addition, in one embodiment, Figure 1The telescopic arm assembly 121 is rotatably mounted on the support device 110, enabling the assembly 121 to drive the submarine cable protection device 200 toward or away from the submarine cable 300. It should be noted that the telescopic arm assembly 121 can be mounted on the support device 110 via a rotating wheel assembly, or alternatively, the assembly 121 can be rotated on the support device 110 via a motor and a bearing assembly (i.e., the bearing assembly is interlocked between the telescopic arm assembly 121 and the motor). This allows the horizontal spacing between the telescopic arm assembly 121 and the submarine cable 300 to be adjusted in both directions by rotating the telescopic arm assembly 121. This provides a simple structure and facilitates configuration, which helps improve the integration performance of the posture adjustment assembly 120.

[0069] In another embodiment, the telescopic arm assembly 121 is used to drive the submarine cable protection device 200 to extend and retract in a direction perpendicular to the submarine cable 300. The supporting device 110 is provided with a slide rail extending along the length of the submarine cable 300. The telescopic arm assembly 121 is slidably mounted on the slide rail, enabling the telescopic arm assembly 121 to drive the submarine cable protection device 200 to slide toward or away from the submarine cable 300.

[0070] In this way, by sliding the telescopic arm assembly 121, the length spacing of the submarine cable protection device 200 relative to the submarine cable 300 can be adjusted, which helps to reduce the difficulty of adjusting the submarine cable protection device 200 in the length direction and helps to improve the alignment accuracy between the submarine cable protection device 200 and the submarine cable 300. Furthermore, the provision of the slide rail enables the telescopic arm assembly 121 to move smoothly along a preset path, reducing the error caused by the shaking of the telescopic arm assembly 121, allowing the submarine cable protection device 200 to be accurately adjusted at any position along the submarine cable 300, and improving the alignment accuracy between the submarine cable protection device 200 and the submarine cable 300.

[0071] Specifically, the horizontal deviation parameter includes a length deviation parameter. The length deviation parameter is positively correlated with the straight-line distance between the submarine cable protection device 200 and the submarine cable 300 along the length direction of the submarine cable 300. Figure 4 As shown, the above step S300 may further include:

[0072] S320. Drive the telescopic arm assembly 121 according to the length deviation parameter, so that the telescopic arm assembly 121 drives the submarine cable protection device 200 to move along the length direction of the submarine cable 300, so that the submarine cable protection device 200 can cover the submarine cable 300.

[0073] At this time, the telescopic arm assembly 121 can drive the submarine cable protection device 200 to move, so that the submarine cable protection device 200 has a movement vector along the length direction of the submarine cable 300, thereby being able to adjust the length direction of the submarine cable protection device 200 relative to the submarine cable 300.

[0074] In order to further improve the alignment accuracy between the submarine cable protection device 200 and the submarine cable 300, Figure 2 In other embodiments, the submarine cable protection device deployment system 100 further includes a current meter 160 for obtaining the ocean current velocity in a predetermined sea area. The current meter 160 is in communication with the calculation module 140 . The calculation module 140 is further configured to receive the ocean current velocity and, based on the ocean current velocity and position information, to drive the posture adjustment component 120 to adjust at least one of the horizontal and vertical postures of the submarine cable protection device 200.

[0075] In one embodiment, if Figure 5 As shown, step S200 also includes:

[0076] S210: Obtain the ocean current speed in the preset sea area.

[0077] S220. According to the first preset relationship, obtain a horizontal deviation parameter related to the ocean current velocity and the horizontal deviation parameter in the first preset relationship.

[0078] It is understood that the ocean current velocity can affect the horizontal attitude of the submarine cable protection device 200. For example, when the ocean current velocity is generally to the left, the submarine cable protection device 200 will have a leftward displacement during the sinking process. After the submarine cable protection device 200 sinks to the bottom, the horizontal attitude of the submarine cable protection device 200 will actually be offset to the left by an additional amount greater than the horizontal deviation parameter. Therefore, the horizontal deviation parameter related to the ocean current velocity and the horizontal deviation can be obtained based on the first preset relationship, thereby improving the accuracy of the horizontal attitude adjustment of the submarine cable protection device 200.

[0079] In conjunction with any embodiment of the posture adjustment component 120, see Figure 1 as well as Figure 2 The attitude adjustment component 120 also includes a height adjustment component, which is used to drive the submarine cable protection device 200 to move along the direction of gravity.

[0080] The calculation module 140 is used to drive the height adjustment component according to the position information, so that the height adjustment component can drive the submarine cable protection device 200 to move to a preset height.

[0081] In this way, unlike sinking to the bottom only by the weight of the submarine cable protection device 200 itself, a certain pulling force is provided by the height adjustment component, which can reduce the sinking speed of the submarine cable protection device 200, thereby improving the movement stability of the submarine cable protection device 200, reducing the risk of position displacement of the submarine cable protection device 200 due to uneven force, and improving the alignment accuracy of the submarine cable protection device 200 and the submarine cable 300.

[0082] Furthermore, in some embodiments, Figures 6 to 8 As shown, the submarine cable protection device 200 further includes a release assembly 150, and the posture adjustment assembly 120 is connected to the submarine cable protection device 200 via the release assembly 150. The calculation module 140 is in communication with the height adjustment assembly 122 and the release assembly 150. The calculation module 140 is used to enable the release assembly 150 to switch from a locked state to an unlocked state when the submarine cable protection device 200 is at a preset height.

[0083] The release assembly 150 has a locked state and an unlocked state. Figure 7 as well as Figure 8 When the release assembly 150 is in the locked state, the submarine cable protection device 200 is locked to the release assembly 150. Figure 6 When the release assembly 150 is in the unlocked state, the release assembly 150 is separated from the submarine cable protection device 200.

[0084] In this way, by providing the release assembly 150 and connecting the posture adjustment assembly 120 to the submarine cable protection device 200 via the release assembly 150, the submarine cable 300 can be ensured to remain stable during transportation, installation, or operation, preventing the submarine cable 300 from loosening or being damaged by external forces (such as wave impact, ship drag, etc.). When the release assembly 150 is in the locked state, the submarine cable protection device 200 is firmly locked to the release assembly 150, allowing the submarine cable protection device 200 to be quickly detached according to actual needs. For example, after the submarine cable protection device 200 is laid, the release assembly 150 can be separated from the submarine cable protection device 200 to facilitate the subsequent recovery of the posture adjustment assembly 120, thereby improving the efficiency of laying and recovering the submarine cable protection device 200.

[0085] Accordingly, if Figure 9 As shown, step S300 may further include:

[0086] S330 , obtaining a height deviation parameter between the submarine cable 300 and the submarine cable protection device 200 according to the position information.

[0087] The height deviation parameter is positively correlated with the height between the submarine cable 300 and the submarine cable protection device 200 .

[0088] S340: driving the attitude adjustment component 120 according to the height deviation parameter, so that the height adjustment component drives the submarine cable protection device 200 to move along the gravity direction, so that the height between the submarine cable protection device 200 and the submarine cable 300 reaches a preset height value.

[0089] It can be understood that within a certain range of preset height values, when the submarine cable protection device 200 moves within the range of preset height values, since the activity distance will not be too long and the influence of external force on its activity range will not change too much, the submarine cable protection device 200 can maintain basic stability and can be accurately aligned with the submarine cable 300.

[0090] S350: Determine whether the horizontal deviation parameter is less than a preset horizontal value, and whether the height deviation parameter is less than a preset height.

[0091] When the horizontal deviation parameter is less than or equal to the preset horizontal value, and the height deviation parameter is less than or equal to the preset height value, step S351 is executed.

[0092] S351 , releasing the submarine cable protection device 200 , so that the posture adjustment component 120 is separated from the submarine cable protection device 200 .

[0093] Otherwise, the process returns to step S340. That is, the attitude adjustment component 120 continues to be driven according to the horizontal deviation parameter and the height deviation parameter. Specifically, when the horizontal deviation parameter is greater than or equal to the preset horizontal value, and / or the height deviation parameter is greater than or equal to the preset height value, the attitude adjustment component 120 continues to be driven to move the submarine cable protection device 200.

[0094] In this way, unlike directly sinking the submarine cable protection device 200 to the seabed through the height deviation component, the method of the above embodiment is conducive to achieving a smooth release of the submarine cable protection device 200, avoiding uneven force on the posture adjustment component 120 when the submarine cable protection device 200 sinks to the bottom, thereby avoiding the displacement of the submarine cable protection device 200 by the posture adjustment component 120, and ensuring the accurate alignment of the submarine cable protection device 200 and the submarine cable 300.

[0095] In another embodiment, in combination with the above embodiment of the water flow meter 160, as shown in FIG. Figure 10 As shown, step S330 also includes:

[0096] S331, obtaining weight data of the submarine cable protection device 200, and obtaining the ocean current speed in a preset sea area.

[0097] Specifically, current meter 160 can be used to obtain the ocean current velocity in a predetermined sea area. Weight data can be obtained from a predetermined database. Furthermore, the ocean current velocity can be obtained by placing current meter 160 in a predetermined water area. In one example, the predetermined sea area is the area surrounding submarine cable 300.

[0098] S332. According to the second preset relationship, obtain a preset height value related to the weight data and the ocean current speed in the second preset relationship.

[0099] Generally, when the descent speed of the submarine cable protection device 200 is fast enough and the free sinking distance of the submarine cable protection device 200 is not too large, due to the effect of inertia, when the ocean current speed tends to be stable, it will not cause excessive changes in the submarine cable protection device 200. At this time, the horizontal posture change of the submarine cable protection device 200 is very small or almost non-existent, and the alignment accuracy between the submarine cable protection device 200 and the submarine cable 300 can still be guaranteed. Among them, the descent speed and inertia are both related to the weight of the submarine cable protection device 200. Based on this, there is a force model related to weight data, sample flow speed and preset height value (i.e., a second preset relationship), and the optimal range of the preset height value can be obtained through the second preset relationship. When the submarine cable protection device 200 is free sinking at the preset height value, if the posture deviation of the submarine cable protection device 200 is less than the limit value, it can ensure that the horizontal posture of the submarine cable protection device 200 can be accurately aligned with the submarine cable 300.

[0100] S333. Drive the attitude adjustment component 120 according to the height deviation parameter and the preset height value, so that the attitude adjustment component 120 can drive the submarine cable protection device 200 to move, so that the height between the submarine cable protection device 200 and the submarine cable 300 reaches the preset height value.

[0101] The movement distance of the submarine cable protection device 200 driven by the posture adjustment component 120 in the gravity direction is positively correlated with the difference between the height deviation parameter and the preset height value.

[0102] In this way, the method in the above embodiment is conducive to improving the accuracy of obtaining the preset height value, thereby greatly reducing the risk of horizontal deviation of the submarine cable protection device 200, and then ensuring the alignment accuracy of the submarine cable protection device 200 and the submarine cable 300.

[0103] It should be noted that the type of the release component 150 can be, but is not limited to, a clamping component, and can also be a hanging rod component, a hanging plate component, etc., and no excessive restrictions are imposed here.

[0104] In some embodiments, such as Figures 6 to 8As shown, the release assembly 150 includes a power source 151, at least one set of telescopic rod assemblies 152, and a support assembly 153. The power source 151 and the telescopic rod assembly 152 are mounted on the support assembly 153. The support assembly 153 is used to mount the submarine cable protection device 200 and connect to the posture adjustment assembly 120. The telescopic rod assembly 152 includes a first telescopic rod 1521 and a second telescopic rod 1522, which are respectively connected to opposite sides of the power source 151 through transmission. The power source 151 is used to drive the first telescopic rod 1521 and the second telescopic rod 1522 to extend and retract in a direction toward or away from each other. Hollow portions 200a are provided on opposite sides of the submarine cable protection device 200. The hollow portions 200a can be formed by a hanging rope on the submarine cable protection device 200, or by a hole formed by cement pouring, etc.

[0105] See you later Figure 7 as well as Figure 8 When the release assembly 150 is in the locked state, the power source 151 is used to drive the first telescopic rod 1521 and the second telescopic rod 1522 to extend and retract in directions away from each other, so that the two oppositely disposed hollow portions 200a of the first telescopic rod 1521 and the second telescopic rod 1522 are engaged with each other. Figure 6 When the release assembly 150 is in the unlocked state, the power source 151 is used to drive the first telescopic rod 1521 and the second telescopic rod 1522 to extend and retract in a direction approaching each other, so that the first telescopic rod 1521 and the second telescopic rod 1522 are both separated from the hollow portion 200a.

[0106] It will be appreciated that when the release assembly 150 is in the locked state, the power source 151 drives the first and second telescopic rods 1521, 1522 to extend and retract in a direction away from each other, causing the telescopic rods to engage with the hollow portion 200a of the submarine cable protection device 200. This engagement ensures that the submarine cable protection device 200 is securely fixed to the release assembly 150 in the locked state, preventing the submarine cable protection device 200 from loosening or falling off due to external forces (such as ocean currents). When the submarine cable protection device 200 needs to be released, the power source 151 drives the first and second telescopic rods 1521, 1522 to extend and retract in a direction toward each other, causing the telescopic rods to separate from the hollow portion 200a, achieving rapid unlocking.

[0107] In this way, the relative arrangement of the first telescopic rod 1521 and the second telescopic rod 1522 is conducive to improving the force balance of the submarine cable protection device 200 during the locking and releasing process, and avoiding the release component 150 from affecting the posture of the submarine cable protection device 200. Furthermore, the release component 150 cooperates with the submarine cable protection device 200 through a snap-fit locking and unlocking method. Different from the methods such as the clamping component and the electromagnet, the snap-fit locking method is conducive to convenient unlocking and greater connection strength, which can provide better connection stability between the posture adjustment component 120 and the submarine cable protection device 200. The setting of the snap-fit structure is relatively simple, which helps to reduce the difficulty of processing.

[0108] It should be noted that the power source 151 can be, but is not limited to, a hydraulic pump, a motor, a pneumatic pump, etc., and no further limitations are given here.

[0109] Further, in some embodiments, Figure 7 The first telescopic rod 1521 and the second telescopic rod 1522 are arranged on the same horizontal plane, so that the first telescopic rod 1521 and the second telescopic rod 1522 move in a direction toward or away from each other on the same horizontal plane. In this way, when the first telescopic rod 1521 and the second telescopic rod 1522 and the hollow portion 200a move on the same horizontal plane, the effect of gravity on the engagement of the first telescopic rod 1521 and the second telescopic rod 1522 with the hollow portion 200a is reduced, preventing the telescopic rod assembly 152 from separating from the hollow portion 200a due to gravity, thereby improving the stability of the locking effect.

[0110] In addition, in another embodiment, Figure 7 The multiple telescopic rod assemblies 152 are sequentially spaced apart on the same horizontal plane. In this way, the multiple telescopic rod assemblies 152 can provide multiple connection points between the release assembly 150 and the submarine cable protection device 200, thereby improving the movement stability of the submarine cable protection device 200.

[0111] In conjunction with any embodiment of the above-mentioned posture adjustment component 120, see Figure 1 as well as Figure 2 The attitude adjustment component 120 further includes an angle adjustment component 123, which is used to drive the submarine cable protection device 200 to rotate relative to the submarine cable 300. The calculation module 140 is also used to drive the angle adjustment component 123 based on the position information so that the submarine cable protection device 200 can remain parallel to the submarine cable 300 through the angle adjustment component 123.

[0112] Specifically, see you later Figure 11 , the above step S300 further includes:

[0113] S350: Obtain a deviation angle parameter between the submarine cable 300 and the submarine cable protection device 200 according to the position information.

[0114] The deviation angle parameter includes at least one of a horizontal deviation parameter and a vertical deviation parameter. The horizontal deviation parameter is positively correlated with the horizontal angle between the line on which the submarine cable 300 is located and the line on which the submarine cable protection device 200 is located. The vertical deviation parameter is positively correlated with the vertical angle between the line on which the submarine cable 300 is located and the line on which the submarine cable protection device 200 is located.

[0115] S360: driving the angle adjustment component 123 according to the deviation angle parameter, so that the angle adjustment component 123 drives the submarine cable protection device 200 to rotate, so that the submarine cable protection device 200 is arranged parallel to the submarine cable 300.

[0116] It is understandable that due to the different ocean current speeds at different locations, the submarine cable protection device 200 may be caused to rotate sideways, causing the submarine cable protection device 200 and the submarine cable 300 to be arranged non-parallel, resulting in poor coverage of the submarine cable protection device 200 over the submarine cable 300. Based on this, in this embodiment, by obtaining the horizontal deviation parameter, the angle adjustment component 123 is used to adjust the rotation angle of the submarine cable protection device 200 to ensure that the submarine cable protection device 200 and the submarine cable 300 are arranged in parallel, thereby improving the alignment accuracy of the submarine cable protection device 200 and the submarine cable 300.

[0117] It should be noted that the angle adjustment component 123 can be, but is not limited to, a rotating component to change the torque, or can be a component that changes the torque by utilizing unbalanced force, etc., and no further restrictions are imposed here.

[0118] In some embodiments, see Figure 1 The angle adjustment assembly 123 includes a first hoist 1231, a second hoist 1232, a first rope 1233, and a second rope 1234. The submarine cable protection device 200 has a first side 210 and a second side 220 facing each other. The first rope 1233 is transmission-connected to the first hoist 1231 and the first side 210. The first hoist 1231 is used to wind the first rope 1233 to adjust the distance between the first hoist 1231 and the submarine cable protection device 200. The second rope 1234 is transmission-connected to the second hoist 1232 and the second side 220. The second hoist 1232 is used to wind the second rope 1234 to adjust the distance between the second hoist 1232 and the submarine cable protection device 200.

[0119] It is understood that when the first hoist 1231 winds the first rope 1233, the length of the first rope 1233 shortens (the length of the first rope 1233 is less than the length of the second rope 1234), and one side of the submarine cable protection device 200 is pulled toward the first hoist 1231, causing the submarine cable protection device 200 to rotate to one side about its axis. When the second hoist 1232 winds the second rope 1234, the length of the second rope 1234 shortens (the length of the second rope 1234 is less than the length of the first rope 1233), and the other side of the submarine cable protection device 200 is pulled toward the second hoist 1232, causing the submarine cable protection device 200 to rotate to the other side about its axis.

[0120] In other words, by controlling the direction and degree of rotation of the first hoist 1231 and the second hoist 1232, respectively, the rotation angle of the submarine cable protection device 200 can be precisely adjusted. The calculation module 140 calculates the required angle based on the deviation angle parameter. By controlling the rotation of the first hoist 1231 and the second hoist 1232, the distance between the two sides of the submarine cable protection device 200 changes, thereby enabling the submarine cable protection device 200 to rotate parallel to the submarine cable 300.

[0121] In this way, unlike the method of directly setting a rotating component on the axis to drive the submarine cable protection device 200 to rotate, the rotation is achieved by controlling the length of the first rope 1233 and the second rope 1234. The setting structure is simpler and the rotation angle is convenient to adjust, which is conducive to improving the use convenience of the submarine cable protection device deployment system 100.

[0122] It should be noted that the first rope 1233 and the second rope 1234 can be installed at the same height or at different heights.

[0123] In one embodiment, see Figure 1 The first side 210 and the second side 220 are arranged relative to each other along the length or width of the cable protector 200. The first hoist 1231 and the second hoist 1232 are installed at the same height. This allows the first rope 1233 and the second rope 1234 to have different lengths, thereby adjusting the horizontal angle of the cable protector 200.

[0124] In another embodiment, the first side 210 and the second side 220 are arranged relative to each other along the height direction of the cable protector 200. The first hoist 1231 and the second hoist 1232 are installed on the same vertical line, which is parallel to the height direction. In this way, the vertical deflection angle of the cable protector 200 can be adjusted by using the different lengths of the first rope 1233 and the second rope 1234.
