DETAILED DESCRIPTION
[0027] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.
[0028] Figure 1 The structural diagram of a drag cutting system provided by an exemplary embodiment of the present application is shown in FIG. Figure 1 As shown, the towing cutting system 200 provided in the embodiment of the present application may include an unmanned boat 210, a connector 220 and a cutting device 100, and the connector 220 may connect the unmanned boat 210 and the cutting device 100. Specifically, in practical applications, the cutting device 100 may be inserted into the seabed formation, and then the unmanned boat 210 may drag the cutting device 100 through the connector 220. When the cutting device 100 clamps the cable, the cable may be cut off under the action of tension, thereby achieving the effect of cutting the cable.
[0029] like Figure 1 As shown, in one embodiment, the connecting member 220 may include a connecting rope 221 and a connecting chain 222, one end of the connecting rope 221 is connected to the unmanned boat 210, the other end of the connecting rope 221 is connected to one end of the connecting chain 222, and the other end of the connecting chain 222 is connected to the cutting device 100. In this way, the unmanned boat 210 can drive the cutting device 100 to move by pulling the connecting rope 221 and the connecting chain 222.
[0030] In one embodiment, the connecting member 220 may also include one of a connecting rope 221 and a connecting chain 222 .
[0031] Figure 2 This is a schematic diagram of the structure of a cutting device provided by an exemplary embodiment of the present application. Figure 2 As shown, the cutting device 100 may include an anchor body 110 and a hook 120 . The anchor body 110 may be connected to the aforementioned connecting member 220 . The hook 120 is connected to the anchor body 110 . A cutting portion 130 is disposed on the inner side of the hook 120 .
[0032] Specifically, in actual application, the unmanned boat 210 drags the anchor body 110 to move through the connecting piece 220, the hook 120 can clamp the cable, the cable enters the cutting area of the cutting part 130, and the cutting part 130 inside the hook 120 cuts the cable to achieve the effect of cutting the cable.
[0033] It should be noted that after the anchor body 110 and the hook 120 are inserted into the seabed stratum, they are easily sunk deeper and deeper under the action of sand and stones, making it difficult for the unmanned boat 210 to drag the anchor body 110 and the hook 120 to move through the connecting rope 221, affecting the cutting efficiency. Figure 2 As shown, the cutting device 100 provided in the embodiment of the present application may further include a limiting body 140, which is connected to the hook 120 and is located outside the hook 120. In practical applications, after the anchor body 110 and the hook 120 are inserted into the seabed formation, they gradually sink downward into the formation. When the limiting body 140 contacts the formation, the limiting body 140 is not easy to sink downward into the seabed formation, thereby limiting the anchor body 110 and the hook 120 from continuing to sink. In this way, on the first hand, the limiting body 140 can prevent the anchor body 110 and the hook 120 from sinking deeper and deeper, improve the problem of dragging difficulty, and effectively improve the cutting efficiency; on the second hand, when the limiting body 140 contacts the seabed formation, it is also ensured that the anchor body 110 and the hook 120 have been inserted into the seabed formation to a certain depth, and it can be ensured that the hook 120 clamps the part of the cable immersed in the seabed formation during the movement, thereby ensuring that the cutting part 130 accurately cuts the cable.
[0034] In one embodiment, the limiting body 140 may be a plate-shaped, column-shaped or other structure.
[0035] like Figure 2 As shown, the hook 120 includes a first mounting end 121 and a second mounting end 122 that are oppositely disposed. The first mounting end 121 is provided with the aforementioned cutting portion 130 , and the limiting body 140 is close to the second mounting end 122 relative to the first mounting end 121 .
[0036] It should be understood that in actual applications, the first mounting end 121 is first inserted into the seabed formation, and then the limiting body 140 is inserted into the seabed formation. Since the limiting body 140 is far away from the first mounting end 121, when the limiting body 140 is inserted into the seabed formation again, it can be ensured that the hook claw 120 has been inserted into a deeper part of the seabed formation. In this way, it can be ensured that the hook claw 120 can completely hold the part of the cable immersed in the seabed formation during the movement, which is convenient for the cutting part 130 to cut the cable.
[0037] like Figure 2As shown, the limiting body 140 is inclined toward the first mounting end 121 and relative to the outer wall of the hook 120, so that there is an angle between the extension direction of the limiting body 140 and the direction in which the hook 120 is inserted into the seabed formation, which can effectively improve the limiting effect of the limiting body 140, that is, when the limiting body 140 contacts the seabed formation, it is less likely to sink into the seabed formation, thereby more effectively limiting the anchor body 110 and the hook 120 from continuing to sink into the seabed formation.
[0038] It should be understood that the inclination angle of the limiting body 140 relative to the outer side wall of the hook claw 120 can be set according to actual conditions, for example, 30°, 40°, 45°, etc.
[0039] like Figure 2 As shown, the side of the limiting body 140 away from the hook 120 is provided with an arc-shaped end 141, so that the limiting body 140 is subjected to force more evenly during the insertion into the seabed formation, and is less likely to experience stress concentration, and is also less likely to break.
[0040] like Figure 2 As shown, the cutting device 100 may further include a barb 150, which is connected to the hook 120, is located on the inner side of the hook 120, and is disposed toward the cutting portion 130 and is inclined relative to the hook 120. In this way, firstly, in the process of the hook 120 clamping the cable, the barb 150 can guide the cable to move toward the cutting portion 130, so that the hook 120 can quickly clamp the cable and improve the overall cutting efficiency of the cable; secondly, after the cable is clamped into the hook 120, the barb 150 can reversely hook the cable, thereby preventing the cable from coming out of the hook 120, and ensuring that the cable is always located in the cutting area of the cutting portion 130 during the cutting process.
[0041] like Figure 2 As shown, the barb 150 and the limiting body 140 are connected to the same part of the hook 120. In this way, when the limiting body 140 contacts the seabed formation, the barb 150 also contacts the seabed formation. The limiting body 140 limits the hook 120 from continuing to sink into the seabed formation, and can also limit the barb 150 from continuing to sink into the seabed formation, thereby ensuring that the barb 150 can continue to hook the cable.
[0042] In one embodiment, the barb 150 and the limiting body 140 may also be connected to different parts of the hook 120 respectively.
[0043] like Figure 2 As shown, there are multiple hooks 120, and the multiple hooks 120 are distributed around the circumference of the anchor body 110. In this way, multiple hooks 120 clamp the cable at the same time, which can improve the clamping stability. During the process of cutting the cable by the cutting part 130, the stability of the cable can be effectively guaranteed, and the cutting efficiency can be improved.
[0044] It should be understood that if Figure 2 As shown, each hook 120 is connected to the aforementioned limiting body 140 and barb 150 .
[0045] like Figure 2 As shown, the anchor body 110 includes a first connecting end 111 and a second connecting end 112 that are oppositely disposed, the first connecting end 111 is connected to the hook 120, and the second connecting end 112 is provided with a lifting ring 113. It should be understood that the lifting ring 113 can be conveniently connected to the aforementioned connecting member 220.
[0046] In one embodiment, the lifting ring 113 and the second connecting end 112 can be connected to each other by welding, hinge or the like.
[0047] In one embodiment, the connection chain 222 is sleeved in the hanging ring 113, which can improve the connection strength between the connection chain 222 and the hanging ring, so that the connection chain 222 and the hanging ring 113 are not easily separated from each other.
[0048] Figure 3 for Figure 2 The enlarged schematic diagram of A in the figure. Figure 3 As shown, the cutting portion 130 includes a V-shaped groove 131, and a cutting tooth 132 is provided in the V-shaped groove 131. Specifically, when the cable reaches the cutting portion 130, the V-shaped groove 131 can hold the cable, and the V-shaped groove 131 plays a limiting role on the cable, and then under the towing action of the unmanned boat 210, the cutting tooth 132 can cut the cable multiple times until the cable is cut off.
[0049] like Figure 3 As shown, guide oblique walls 133 extend from both ends of the V-shaped groove 131 , and the guide oblique walls 133 can guide the cable to slide into the V-shaped groove 131 , so that the V-shaped groove 131 can hold the cable.
