Description

Technical Field

[0001] The present invention mainly relates to the technical field of submarine cable laying, and specifically relates to a submarine cable dynamic anchoring device for submarine cable laying construction. Background Art

[0002] The existing method of laying submarine cables is to first use a submarine cable ship to transport the submarine cable to a predetermined location, then use a landing ship to tow the submarine cable to the beach, and finally use a dynamic anchoring device to fix the submarine cable.

[0003] The submarine cable is mainly fixed by clamping with installation clamps, bolts and nuts. However, due to the humid beach environment, the bolts and nuts are prone to rust over a long period of time, affecting subsequent maintenance and replacement. In addition, the submarine cable is constantly pulled during laying, which can easily cause the bolts and nuts to loosen, thus affecting the fixing effect of the submarine cable. Therefore, a new type of submarine cable dynamic anchoring device for submarine cable laying construction is needed. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. It mainly provides a submarine cable dynamic anchoring device for submarine cable laying construction, which is used to solve the technical problems raised in the above background technology that the bolts and nuts are rusted and affect the subsequent maintenance and replacement, and the submarine cable is pulled during laying, causing the bolts and nuts to loosen.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A submarine cable dynamic anchoring device for submarine cable laying construction comprises a V-shaped plate arranged on a shore, a plurality of through holes are provided at the center of the lower surface of the V-shaped plate, a support member is inserted into the through holes, the submarine cable is arranged on the support member, a plurality of staggered rectangular grooves are provided on the left and right sides of the V-shaped plate, circular grooves are provided on two opposite side surfaces of the rectangular grooves, a clamping member is installed in the circular groove, the submarine cable is arranged between the two clamping members, and the support member is in contact with the clamping member.

[0007] Preferably, the supporting member comprises a triangular block, which is arranged in a V-shaped plate, a plurality of limit rods are installed on the lower surface of the triangular block, the limit rods are inserted in the through holes, circular holes are opened on the left and right sides of the upper surface of the triangular block, abutments are arranged in the circular holes, the submarine cable is arranged between the two abutments, and the end of the abutment away from the submarine cable is in contact with the clamping member.

[0008] Preferably, the abutment member comprises a round rod inserted in the round hole, one end of the round rod away from the triangular block contacts the clamping member, one end of the round rod away from the clamping member is installed with an arc block, and the submarine cable is arranged between the two arc blocks.

[0009] Preferably, the clamping member includes an arc-shaped plate, the arc-shaped plate is arranged in a rectangular groove, the submarine cable is arranged between two arc-shaped plates, the end of the round rod away from the triangular block is in contact with the arc-shaped plate, and the arc-shaped plate has through grooves on both sides facing the circular groove, a rotating rod is inserted in the through groove, and both ends of the rotating rod are inserted in the circular groove.

[0010] Preferably, a transverse groove is provided on the opposite sides of the two arc-shaped plates, and the transverse groove is in rotational contact with the round rod.

[0011] Preferably, a plurality of fixing anchors are installed on both left and right sides of the lower surface of the V-shaped plate, and the fixing anchors and the rectangular grooves are arranged alternately.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By opening a plurality of staggered rectangular grooves on both sides of the V-shaped plate, and installing a clamping structure consisting of a rotating rod and an arc plate in the rectangular groove, the gravity of the submarine cable is used to press the round rod so that the arc plate can reverse and fix the submarine cable, thereby making the installation and removal of the submarine cable more convenient.

[0014] 2. When the submarine cable enters the two curved plates, the round rod is pressed by the gravity of the submarine cable to continuously squeeze the curved plates, causing the end of the curved plate away from the rotating rod to deflect, thereby changing the size of the space formed by the two opposite curved plates, thereby meeting the installation and use of submarine cables of different thicknesses.

[0015] 3. As the arc plate rotates and the round rod is inserted into the transverse groove, one side of the round rod contacts the edge of the submarine cable and forms a resisting force. As the length of the submarine cable laid on the seabed increases, the arc plate is subjected to greater gravity of the submarine cable, and the round rod goes deeper into the transverse groove, so that the arc plate is subjected to greater pressure and it is more difficult to deflect to the side away from the submarine cable, thereby preventing the submarine cable from loosening and detaching when being pulled.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Please refer to the attached Figure 1-Figure 4 A submarine cable dynamic anchoring device for submarine cable laying construction comprises a V-shaped plate 1 arranged on a shore, a plurality of fixed anchors 2 are installed on the left and right sides of the lower surface of the V-shaped plate 1, a plurality of through holes are opened at the center of the lower surface of the V-shaped plate 1, and limiting rods 7 are inserted into the through holes, a triangular block 5 is arranged in the V-shaped plate 1, and the limiting rod 7 is connected to the triangular block 5, circular holes are opened on the left and right sides of the upper surface of the triangular block 5, and round rods 4 are inserted into the circular holes, an arc block 6 is installed on the upper end of the round rod 4, and the submarine cable is arranged between the two arc blocks 6 and is in sliding contact with the arc block 6.

[0027] A plurality of staggered rectangular grooves 8 are provided on both sides of the V-shaped plate 1. The rectangular grooves 8 are alternately arranged with the fixed anchors 2. An arc-shaped plate 3 is provided in the rectangular groove 8. The submarine cable is provided between the arc-shaped plates 3 on both sides. A through groove is provided in the arc-shaped plate 3. A rotating rod 9 is rotatably connected in the through groove. Circular grooves are provided on two opposite sides of the rectangular groove 8. Both ends of the rotating rod 9 are inserted in the circular grooves. Transverse grooves 10 are provided on opposite sides of the two arc-shaped plates 3. The transverse grooves 10 are in rotational contact with the round rod 4.

[0028] A clamping structure consisting of a rotating rod 9 and an arc plate 3 is installed in the rectangular groove 8. When the submarine cable is placed on the arc block 6, the arc block 6 is subjected to the gravity of the submarine cable and is transmitted to the arc plate 3 through the round rod 4 and squeezes the arc plate 3. The clamping structure reverses and fixes the submarine cable, thereby facilitating the installation and removal of the submarine cable. At the same time, after the submarine cable enters the two arc plates 3, the round rod 4 is pressed by the gravity of the submarine cable and continuously squeezes the arc plate 3, causing the end of the arc plate 3 away from the rotating rod 9 to deflect, thereby changing the size of the space formed by the two opposite arc plates 3, thereby meeting the installation and use of submarine cables of different thicknesses.

[0029] When the arc plate 3 is rotated so that the round rod 4 is completely inserted into the transverse groove 10, the arc plate 3 reaches the maximum rotation angle. At this time, the space formed by the arc plates 3 on both sides is the minimum limitable cable. Since the arc plates 3 on the left and right sides of the V-shaped plate 1 are arranged alternately, the arc plates 3 will not contact each other and produce conflict when they move toward the center of the V-shaped plate 1.

[0030] The specific operation process of the present invention is as follows: when laying the submarine cable, the position of the V-shaped plate 1 is first fixed by using the fixed anchor 2, and then the triangular block 5 is installed in the V-shaped plate 1 by using multiple limit rods 7, and then the supporting structure composed of the round rod 4 and the arc block 6 is inserted into the round hole, and one end of the round rod 4 is in contact with the arc plate 3. At this time, the round rod 4 does not contact the transverse groove 10.

[0031] When the submarine cable is laid on the two arc blocks 6, the submarine cable is held under the weight of the submarine cable, and the round rod 4 squeezes the arc plate 3, causing the arc plate 3 to deflect with the rotating rod 9 as the center, thereby reversely wrapping the submarine cable and making the round rod 4 approach the transverse groove 10 and insert into the transverse groove 10. As the arc plate 3 rotates and the round rod 4 is inserted into the transverse groove 10, one side of the round rod 4 contacts the edge of the submarine cable and forms a resisting force. As the length of the submarine cable laid on the seabed increases, the greater the gravity of the submarine cable is applied to the arc plate 3, and the deeper the round rod 4 goes into the transverse groove 10, the greater the pressure on the arc plate 3 and the more difficult it is to deflect to the side away from the submarine cable, thereby preventing the submarine cable from loosening and detaching when being pulled.

[0032] When the submarine cable needs to be recovered and replaced, the submarine cable laying equipment lifts the submarine cable upward, so that the arc plate 3 loses the pressure of the submarine cable, so that it can be easily deflected to the side away from the submarine cable, and then the submarine cable is easily separated from the V-shaped plate 1.

[0033] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
