[0002] With the development of submarine cable power transmission technology, submarine cables are widely used in offshore platforms and island power supply, marine clean energy transmission and cross-regional power transmission. During the operation of submarine cables, some areas are exposed due to long-term erosion by ocean currents, which in turn causes damage to the submarine cables. After the submarine cables are damaged, troubleshooting and repair are difficult and the repair period is long. Therefore, it is necessary to cover the exposed submarine cables.

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0040] A material fixed-point delivery ship for anti-scour protection according to an embodiment of the present application comprises an operating ship, a crane, and a material fixed-point delivery device for anti-scour protection. The operating ship is used to place the material fixed-point delivery device for anti-scour protection. The crane is provided on the operating ship, and the crane is used to lower the material fixed-point delivery device for anti-scour protection into the sea.

[0041] During operation, the operation vessel is moored above the exposed submarine cable. Then, the crane puts the material fixed-point delivery device for anti-scour protection into the sea, and the material fixed-point delivery device for anti-scour protection delivers the material onto the exposed submarine cable. In this way, the exposed submarine cable is covered and protected by the material, which can prevent the submarine cable from being exposed for a long time and being damaged, and ensure the safe and stable operation of the submarine cable.

[0042] It should be noted that the material is a cement sandbag. Of course, in other embodiments, the material can also be other materials, which is not limited to this.

[0043] It should be noted that the material point delivery ship used for anti-scour protection is not only applicable to the material protection construction of submarine cables, but also to the material protection construction of underwater facilities such as pipelines and structures in the sea area, and has a wide range of applications. This article describes the material protection construction of submarine cables.

[0044] See also Figure 1, a material fixed-point delivery device for anti-scour protection provided in one embodiment of the present application includes a device body 10. The device body 10 includes a silo 11 and a bottom plate 12. The silo 11 is provided with a storage cavity 111 and a delivery port 112. The storage cavity 111 is used to store materials, and the storage cavity 111 is connected to the delivery port 112. The bottom plate 12 is movably arranged at the delivery port 112, and the bottom plate 12 can move relative to the silo 11, so that the device body 10 has a storage state in which the bottom plate 12 covers the delivery port 112 and a delivery state in which the delivery port 112 is exposed. In the delivery state, the material can fall through the delivery port 112 and cover the submarine cable.

[0045] When the above-mentioned material fixed-point delivery device for anti-scouring protection is in operation, the device body 10 is in a closed state, and the bottom plate 12 covers the delivery port 112, so that the operator can place the material in the storage chamber 111. Then, the material fixed-point delivery device for anti-scouring protection is placed in the sea, and the position of the material fixed-point delivery device for anti-scouring protection is adjusted so that the material fixed-point delivery device for anti-scouring protection is located directly above the submarine cable. Then, the bottom plate 12 moves relative to the silo 11 to expose the delivery port 112, so that the material falls from the delivery port 112 under its own gravity and covers the submarine cable, so that the material can cover the exposed submarine cable to prevent the submarine cable from being exposed for a long time and being damaged, and ensure the safe and stable operation of the submarine cable. In this way, through the material fixed-point delivery device for anti-scouring protection, the material can be quickly delivered at a fixed point, so that the entire construction process is mechanized and the construction period is shortened. At the same time, there is no need for operators to dive underwater to deliver materials, avoiding the safety risks of operators working underwater.

[0046] In one embodiment, see Figure 1 The bottom plate 12 includes a movable plate body 121, and the movable plate body 121 is movably connected to the material bin 11. In the material storage state, the movable plate body 121 covers the loading port 112.

[0047] Further, see Figure 1 The material fixed-point delivery device for anti-scouring protection further includes a driving mechanism 20. Optionally, the driving mechanism 20 is a hydraulic cylinder. The driving mechanism 20 is connected to the movable plate body 121, and the driving mechanism 20 is used to drive the movable plate body 121 to move relative to the silo 11 to expose the delivery port 112.

[0048] Before the material is put in, the movable plate body 121 covers the putting-in port 112 , and the movable plate body 121 can support the material.

[0049] When the material is put into the storage bin, the driving mechanism 20 drives the movable plate 121 to move relative to the storage bin 11 to expose the putting port 112. The material falls from the putting port 112 under its own gravity and covers the submarine cable to cover and protect the exposed submarine cable.

[0050] In one embodiment, see Figure 1 , there are two movable plate bodies 121. The two movable plate bodies 121 are arranged side by side, and the two movable plate bodies 121 are both slidably connected to the silo 11.

[0051] Further, see Figure 1 The driving mechanism 20 is connected to the two movable plate bodies 121, and the driving mechanism 20 is used to drive the two movable plate bodies 121 to move closer to or away from each other.

[0052] Optionally, see Figure 1 The driving mechanism 20 has a first output shaft 21 and a second output shaft 22. The first output shaft 21 is connected to one of the movable plates 121, and the second output shaft 22 is connected to the other movable plate 121.

[0053] Of course, in other embodiments, two driving mechanisms 20 are provided, and each of the two driving mechanisms 20 has an output shaft, and the two driving mechanisms 20 are respectively connected to the two movable plate bodies 121 in a one-to-one correspondence.

[0054] Before the material is put in, the two movable plates 121 both cover the putting-in opening 112 , and at this time, the two movable plates 121 are aligned.

[0055] When the material is put in, the driving mechanism 20 drives the two movable plates 121 to move away from each other to expose the putting port 112, so that the material falls from the putting port 112 under its own gravity and covers the submarine cable to cover and protect the exposed submarine cable. In this way, the driving mechanism 20 drives the two movable plates 121 to move synchronously, which can increase the speed of opening the putting port 112, thereby improving the material putting efficiency.

[0056] Of course, in other embodiments, the bottom plate 12 may also be rotatably connected to the silo 11. When materials are put in, the driving mechanism 20 drives the bottom plate 12 to rotate out of the material storage cavity 111 to expose the putting-in port 112.

[0057] In one embodiment, see Figure 1 The material fixed-point delivery device for anti-scouring protection further includes a propeller 30. Optionally, the propeller 30 is a hydraulic propeller. The propeller 30 is arranged on the device body 10, and the propeller 30 is used to drive the device body 10 to move.

[0058] Optionally, four propellers 30 are provided, and the four propellers 30 correspond to the four corners of the silo 11 respectively.

[0059] In one embodiment, see Figure 1 The material fixed-point delivery device for anti-scouring protection further includes a positioning module 40. The positioning module 40 is used to obtain the position information of the device body 10.

[0060] During operation, the crane puts the material fixed-point delivery device for anti-scour protection into the sea, and the positioning module 40 obtains the position information of the material fixed-point delivery device for anti-scour protection in real time. The operator adjusts the position of the crane according to the position information of the material fixed-point delivery device for anti-scour protection, so that the material fixed-point delivery device for anti-scour protection is located directly above the submarine cable. In this way, the accuracy of material delivery can be improved.

[0061] In one embodiment, see Figure 1 The positioning module 40 includes a transceiver and a beacon 41. The transceiver is arranged on the working vessel, and optionally, the ultra-short baseline is arranged on the bottom of the working vessel. The beacon 41 is arranged on the device body 10, and the beacon 41 is provided with an acoustic responder.

[0062] The crane puts the fixed-point material delivery device for anti-scouring protection into the sea, and the transceiver sends an inquiry signal to the underwater beacon 41. The acoustic responder on the beacon 41 sends a response signal after receiving the signal from the transceiver. The transceiver measures the round-trip time of the acoustic signal to determine the distance between the fixed-point material delivery device for anti-scouring protection and the transceiver, thereby obtaining the position information of the fixed-point material delivery device for anti-scouring protection.

[0063] Optionally, the beacon 41 is disposed in the middle of a side wall of the silo 11. In this way, the positioning accuracy can be improved.

[0064] In one embodiment, see Figure 1 The device for fixed-point delivery of materials for anti-scouring protection also includes an altimeter 50. The altimeter 50 is arranged on the device body 10, and optionally, the altimeter 50 is arranged on the silo 11. The altimeter 50 is used to detect the vertical distance between the device body 10 and the seabed. The crane puts the device for fixed-point delivery of materials for anti-scouring protection into the sea, and the altimeter 50 measures the vertical distance between the device body 10 and the seabed in real time. When the vertical distance between the device body 10 and the seabed is a preset distance, the crane stops lowering the device for fixed-point delivery of materials for anti-scouring protection to prevent the device for fixed-point delivery of materials for anti-scouring protection from touching the seabed, thereby preventing the device for fixed-point delivery of materials for anti-scouring protection and the submarine cable from being damaged.

[0065] Optionally, the preset distance is 50 cm. Of course, in other embodiments, the preset distance can also be set according to actual needs, and is not limited thereto.

[0066] In one embodiment, see Figure 1 The material fixed-point delivery device for anti-scour protection further includes a navigation module 60. The navigation module 60 is disposed on the device body 10, and the navigation module 60 is used to obtain the orientation information of the device body 10.

[0067] Furthermore, the material fixed-point delivery ship for anti-scour protection also includes a display screen, which is communicatively connected to the navigation module 60, and the display screen is used to display the relative position of the material fixed-point delivery device for anti-scour protection and the submarine cable.

[0068] During operation, the navigation module 60 monitors the position information of the device body 10 in real time, and sends the position information of the fixed-point delivery device for anti-scour protection to the display screen, which displays the relative position of the fixed-point delivery device for anti-scour protection and the submarine cable. The operator adjusts the fixed-point delivery device for anti-scour protection so that the fixed-point delivery device for anti-scour protection is parallel to the direction of the submarine cable.

[0069] In one embodiment, the navigation module 60 is an inertial navigation module. The inertial navigation module is based on Newton's laws of mechanics, and measures the acceleration and angular acceleration of the device body 10 in the inertial reference system, integrates it once over time, obtains the speed and angular velocity of the moving carrier, and then performs a second integration to obtain the position information of the device body 10, and then transforms it to the navigation coordinate system to obtain the speed, yaw angle and position information in the navigation coordinate system.

[0070] The present application also provides a method for placing materials at a fixed point for anti-scour protection, and provides a device for placing materials at a fixed point for anti-scour protection according to any of the above embodiments. The method for placing materials at a fixed point for anti-scour protection comprises the following steps:

[0071] S100: placing materials in the silo 11;

[0072] S200: placing a material fixed-point delivery device for anti-scour protection into the sea;

[0073] S300: adjusting the position of the fixed-point material delivery device for anti-scour protection so that the fixed-point material delivery device for anti-scour protection is located directly above the submarine cable;

[0074] S400: Open the delivery port 112, and the material falls onto the submarine cable under the action of gravity.

[0075] During operation, the material is placed in the silo 11. Then, the material fixed-point delivery device for anti-scour protection is placed in the sea. The position of the material fixed-point delivery device for anti-scour protection is adjusted so that the material fixed-point delivery device for anti-scour protection is located directly above the submarine cable. Then, the delivery port 112 is opened, and the material falls from the delivery port 112 onto the submarine cable under its own gravity, so that the material can cover the exposed submarine cable to prevent the submarine cable from being exposed for a long time and being damaged, thereby ensuring the safe and stable operation of the submarine cable.

[0076] In one embodiment, step S100 specifically includes the following steps:

[0077] S110: laying geotextile in the silo 11;

[0078] S120: Place the material on the geotextile.

[0079] When the material falls from the delivery port 112, the geotextile can wrap the material to prevent the material from scattering under the impact of seawater, thereby ensuring that the material can better cover and protect the exposed submarine cable.

[0080] In one embodiment, in step S120, materials are stacked in a decreasing layer-by-layer manner from the bottom to the top of the silo 11 .

[0081] It can be understood that the amount of material in the bottom layer is the largest, and the amount of material in the top layer is the smallest, and the amount of material gradually decreases in the direction from the bottom layer to the top layer.

[0082] Optionally, the materials are stacked in a five-four-three-two-one manner from the bottom to the top of the silo 11 .

[0083] In one embodiment, between step S100 and step S200, the following steps are further included:

[0084] The work boat is moored above the submarine cable where the materials need to be dropped, which helps to improve the accuracy of material drop.

[0085] In one embodiment, step S300 specifically includes the following steps:

[0086] S310: Obtaining the location information of the material delivery device.

[0087] Specifically, the positioning module 40 of the fixed-point material delivery device for anti-scour protection is used to obtain the underwater position information of the fixed-point material delivery device for anti-scour protection.

[0088] Optionally, the positioning module 40 includes a transceiver and a beacon 41. The transceiver is provided on the work boat. The beacon 41 is provided on the device body 10, and the beacon 41 is provided with an acoustic responder.

[0089] The crane puts the fixed-point material delivery device for anti-scouring protection into the sea, and the transceiver sends an inquiry signal to the underwater beacon 41. The acoustic responder on the beacon 41 sends a response signal after receiving the signal from the transceiver. The transceiver measures the round-trip time of the acoustic signal to determine the distance between the fixed-point material delivery device for anti-scouring protection and the transceiver, thereby obtaining the position information of the fixed-point material delivery device for anti-scouring protection.

[0090] S320: According to the position information, the crane is adjusted so that the material fixed-point delivery device for anti-scour protection is located directly above the submarine cable.

[0091] In one embodiment, between step S300 and step S400, the method further includes the following steps:

[0092] Measure the vertical distance between the material placement device used for anti-scour protection and the seabed.

[0093] Specifically, the altimeter 50 of the material fixed-point delivery device for anti-scour protection is used to measure the vertical distance between the material fixed-point delivery device for anti-scour protection and the seabed.

[0094] When the vertical distance between the fixed-point material delivery device for anti-scour protection and the seabed is a preset distance, the lowering of the fixed-point material delivery device for anti-scour protection is stopped.

[0095] Optionally, the preset distance is 50 cm. In this way, the material fixed-point delivery device for anti-scour protection can be prevented from contacting the seabed, thereby preventing the material fixed-point delivery device for anti-scour protection and the submarine cable from being damaged.

[0096] In one embodiment, after step S300 and before step S400, the method further includes the following steps:

[0097] Obtain the location information of the material fixed-point delivery device used for anti-scour protection.

[0098] Specifically, the navigation module 60 of the device for placing materials at a fixed point for anti-scour protection is used to obtain the position information of the device for placing materials at a fixed point for anti-scour protection.

[0099] The fixed-point material delivery device for anti-scour protection is adjusted so that the fixed-point material delivery device for anti-scour protection is parallel to the direction of the submarine cable.

[0100] During operation, the navigation module 60 monitors the position information of the device body 10 in real time, and sends the position information of the fixed-point delivery device for anti-scour protection to the display screen, which displays the relative position of the fixed-point delivery device for anti-scour protection and the submarine cable. The operator manually operates the propeller 30 to adjust the fixed-point delivery device for anti-scour protection so that the fixed-point delivery device for anti-scour protection is parallel to the direction of the submarine cable.

[0101] In one embodiment, after step S400, the method further includes the following steps:

[0102] S500: Recover the material fixed-point delivery device used for anti-scour protection to the operating vessel.

[0103] In this way, after the material fixed-point delivery device used for anti-scour protection is recovered onto the work vessel, the work vessel can travel to the next location to carry out construction in a cycle.
