Description

Technical Field

[0001] This invention relates to the field of deep-sea mooring technology, and in particular to a torpedo anchor ejection device. Background Technology

[0002] Among related technologies, offshore oil and gas extraction is quite common. In particular, resource exploration and development on the continental shelf at depths exceeding 3000m are experiencing explosive growth. In marine resource exploration, the stability of offshore exploration equipment requires advanced mooring systems as a foundation. Therefore, manufacturing stable, reliable, economical, and deep-sea-environment-suitable mooring equipment for floating platforms is becoming increasingly important.

[0003] A torpedo anchor is a foundation used for mooring deep-sea facilities. Shaped like a torpedo, its outer surface is a conical cylindrical steel tube. During installation, the torpedo anchor is released at a certain water depth, and it relies on the kinetic energy gained from its own weight to rise to the seabed. Installation is quick and simple, making it an economical alternative to traditional marine anchors.

[0004] The load-bearing capacity of torpedo anchors directly affects the stability of marine structures. The greater the penetration depth of a torpedo anchor, the higher its pull-out resistance, and the better the safety of the marine structure. In existing technologies, when torpedo anchors penetrate into the deep sea, they are affected by seawater resistance and complex marine geological conditions, resulting in a certain amount of energy loss during the penetration process, which leads to lower penetration accuracy and depth. Summary of the Invention

[0039] Please refer to Figure 1 and Figure 2 In some embodiments, the torpedo anchor ejection device 10 includes a torpedo anchor 100 and an ejection assembly 200. The torpedo anchor 100 can specifically be a foundation for mooring deep-sea facilities, shaped like a torpedo, with a conical cylindrical steel tube exterior. Further, the ejection assembly 200 can drive the torpedo anchor 100 to move and detach it, thereby providing a certain amount of power to the torpedo anchor 100. Specifically, please refer to... Figure 2 , Figure 2 This is a schematic diagram of the torpedo anchor 100 after detaching from the catapult assembly 200. The catapult assembly 200 is detachably connected to the torpedo anchor 100; that is, before the catapult assembly 200 drives the torpedo anchor 100, the torpedo anchor 100 is connected to the catapult assembly 200. After the catapult assembly 200 drives the torpedo anchor 100, the torpedo anchor 100 detaches from the catapult assembly 200, thus penetrating the deep sea. Specifically, the catapult assembly 200 can drive the torpedo anchor 100 and cause it to detach. Since the catapult assembly 200 can drive the torpedo anchor 100, it can provide a certain amount of kinetic energy to the torpedo anchor 100, thereby increasing the power of the torpedo anchor 100 to penetrate the deep sea. Furthermore, because the torpedo anchor 100 has increased kinetic energy, its penetration accuracy and depth are higher when it enters the deep sea.

[0040] In existing technologies, when a torpedo anchor 100 penetrates deep into the sea, it experiences energy loss due to seawater resistance. However, the ejection component 200 in the torpedo anchor ejection device 10 of this application provides the torpedo anchor 100 with kinetic energy, thereby counteracting seawater resistance and preventing further energy loss. Therefore, the torpedo anchor 100 in the torpedo anchor ejection device 10 of this application can achieve higher penetration accuracy and depth.

[0041] Because the catapult assembly 200 provides a certain amount of power to the torpedo anchor 100, it minimizes the impact of buoyancy on the torpedo anchor 100, thereby improving the penetration depth and accuracy of the torpedo anchor 100. Therefore, in addition to the catapult assembly 200 driving the torpedo anchor 100, the torpedo anchor 100 can also move on its own, further improving the penetration depth and accuracy of the torpedo anchor 100 into the deep sea. Please refer to... Figure 3 and Figure 5 In some embodiments, the torpedo anchor 100 includes a drive device 110, a main body 120, and an anchor wing 130. The drive device 110 can drive the main body 120 to rotate relative to the anchor wing 130. Specifically, when the torpedo anchor 100 disengages from the catapult assembly 200, the drive device 110 drives the main body 120 to rotate relative to the anchor wing 130. The following is a detailed description of this embodiment: The main body 120 may have a cylindrical shape. When the drive device 110 drives the main body 120 to rotate relative to the anchor wing 130, the drive device 110 can provide rotational kinetic energy to the main body 120, thereby increasing the rotational kinetic energy on top of the kinetic energy added to the torpedo anchor 100 by the catapult assembly 200. After the main body 120 is given additional kinetic and rotational kinetic energy, its energy for penetrating the deep sea is further increased, reducing the impact of seawater resistance and increasing the kinetic energy for penetrating the seabed, thereby improving penetration accuracy and depth.

[0042] Furthermore, it should be noted that the drive device 110 can only add rotational kinetic energy to the main body 120 after the torpedo anchor 100 is detached from the catapult assembly 200. Therefore, when the torpedo anchor 100 is connected to the catapult assembly 200, the main body 120 and the anchor wing 130 will not rotate relative to each other.

[0043] The following section will detail the specific structure of the ejection assembly 200 in the torpedo anchor ejection device 10, thereby explaining how the ejection assembly 200 drives the torpedo anchor 100. Please refer to... Figure 4 and Figure 5In some embodiments, the catapult assembly 200 includes an elastic element 210, a fixing plate 220, and a launch tube 230. The launch tube 230 houses the elastic element 210. The torpedo anchor 100 is detachably connected to the fixing plate 220, meaning the torpedo anchor 100 can be detached from the fixing plate 220. The launch tube 230 has a launch cavity 231, within which a portion of the torpedo anchor 100, the elastic element 210, and the fixing plate 220 are disposed. One end of the elastic element 210 is connected to the bottom wall of the launch cavity 231, and the other end is connected to the fixing plate 220. The elastic element 210 can drive the fixing plate 220 to move the torpedo anchor 100 relative to the launch tube 230 along the length of the launch tube 230. Specifically, the elastic element 210 can be a spring. After the spring is placed in the launch cavity 231, the fixing plate 220 and the torpedo anchor 100 can compress the spring, putting it in a compressed state. Then, the spring returns to its original position, driving the fixing plate 220 to move the torpedo anchor 100 relative to the launch tube 230. In this way, by compressing the spring through the fixing plate 220, the fixing plate 220 drives the torpedo anchor 100 to move, thus enabling the catapult assembly 200 to drive the torpedo anchor 100 to move.

[0044] Furthermore, since the fixing plate 220 is located within the launch chamber 231, when the spring is compressed, its return to its original position can drive the fixing plate 220 to move. Therefore, the fixing plate 220 may be driven by the spring to move away from the launch chamber 231. It is conceivable that the torpedo anchor ejection device 10 is a reusable device, not a disposable one. Therefore, if the fixing plate 220 leaves the launch chamber 231 and falls into the deep sea, it may be difficult to retrieve. For reusability, it is necessary to prevent the fixing plate 220 from being lost. Therefore, please refer to... Figure 6 and Figure 7 In some embodiments, the launching tube 230 further has a fixing hole 232 communicating with the launching cavity 231. There may be multiple fixing holes 232, which can be disposed on the sidewall of the launching cavity 231 and extend along the length of the launching tube 230. The fixing plate 220 has a protrusion 221. There may be two fixing plates 220 and two protrusions 221. The protrusions 221 protrude from the outer edge of the fixing plate 220 and are slidably disposed in the fixing hole 232. When the protrusions 221 abut against the sidewall of the fixing hole 232, they can restrict the movement of the fixing plate 220 within the launching cavity 231.

[0045] Specifically, the method by which the fixing plate 220 and the torpedo anchor 100 compress the spring and how the spring drives the movement of the fixing plate 220 will be explained again. The fixing plate 220 and the torpedo anchor 100 can abut against each other and jointly compress the spring, keeping it in a compressed state. When the spring returns to its original position, it can drive the movement of the fixing plate 220 and the torpedo anchor 100; that is, the spring provides power to the fixing plate 220 and the torpedo anchor 100. When the fixing plate 220 moves, the protrusion 221 also moves, and after moving a certain distance, the protrusion 221 abuts against the side wall of the fixing hole 232, thus stopping its movement. Furthermore, when the protrusion 221 stops moving, it also restricts the movement of the fixing plate 220, thus stopping the fixing plate 220 from moving. In this way, the fixing plate 220 will not leave the launching cavity 231.

[0046] The above describes the situation where the fixing plate 220 and the torpedo anchor 100 jointly compress the elastic element 210. It's conceivable that when the elastic element 210 is compressed, it doesn't need to immediately return to its original position to provide power to the torpedo anchor 100. Instead, the elastic element 210 needs to provide power to the torpedo anchor 100 at specific times, such as when the torpedo anchor 100 penetrates deep into the sea. Therefore, after the fixing plate 220 and the torpedo anchor 100 jointly compress the elastic element 210, the elastic element 210 can remain in a compressed state. The following explains how to maintain the compressed state of the elastic element 210; please refer to [link / reference]. Figure 1 , Figure 6 and Figure 8In some embodiments, the launch tube 230 further has a launch groove 233 communicating with the launch cavity 231, and the launch tube 230 also has a locking groove 234 communicating with the launch groove 233, the launch groove 233 extending along the length direction of the launch tube 230. The anchor wing 130 is slidably disposed in the launch groove 233, and the locking groove 234 can engage with the end of the anchor wing 130 so that the anchor wing 130 and the fixing plate 220 jointly compress the elastic member 210. The specific way in which the locking groove 234 can engage with the end of the anchor wing 130 can be: the anchor wing 130 can include interconnected blades 134 and cylinders 136, multiple blades 134 are provided, circumferentially surrounding the cylinder 136, and the blades 134 engage with the groove wall of the locking groove 234. Specifically, part of the torpedo anchor 100, the elastic member 210 and the fixing plate 220 are all disposed within the launch cavity 231. The launch tube 230 is equipped with a launch slot 233 that engages with the anchor wing 130 of the torpedo anchor 100, allowing the torpedo anchor 100 to be placed in the launch chamber 231. Furthermore, when the anchor wing 130 is engaged in the slot 234, the engagement between the anchor wing 130 and the slot 234 is an interference fit. Thus, after the anchor wing 130 is engaged in the slot 234, the torpedo anchor 100 abuts against the fixing plate 220, and the fixing plate 220 compresses the elastic element 210, which remains compressed. It should be noted that when the anchor wing 130 is engaged in the slot 234, the force between them can be exactly equal to the elastic force of the elastic element 210 under compression. That is, as long as an external force is applied, the elastic force of the elastic element 210 can drive the fixing plate 220 and the torpedo anchor 100 to move, thereby causing the anchor wing 130 to disengage from the slot 234. Thus, the cooperation between the slot 234 and the anchor wing 130 can, on the one hand, keep the elastic element 210 in a compressed state, and on the other hand, when affected by external forces, can reset the elastic element 210 and disengage from the compressed state.

[0047] The previous section explained how to keep the elastic element 210 in a compressed state. Now, we will explain how to disconnect the anchor wing 130 from the slot 234, thereby resetting the elastic element 210. When the elastic element 210 resets, it drives the fixed plate 220 and the torpedo anchor 100 to move, providing power to the torpedo anchor 100. Please refer to... Figure 2In some embodiments, the torpedo anchor catapult 10 further includes a mounting anchor chain 400 and a working anchor chain 300. One end of the mounting anchor chain 400 is connected to the end of the launch tube 230, and the other end is connected to a marine structure. Thus, when the torpedo anchor catapult 10 is lowered into the deep sea, the mounting anchor chain 400 pulls on the launch tube 230, preventing it from falling further into the deep sea. Simultaneously, the mounting anchor chain 400 provides an upward pulling force to the launch tube 230, which, together with the gravity of the torpedo anchor 100, breaks the interference fit between the anchor wing 130 and the slot 234, causing the anchor wing 130 to disengage from the slot 234. After the anchor wing 130 disengages from the slot 234, the elastic element 210 can reset and drive the fixing plate 220 and the torpedo anchor 100 to move, thereby providing power to the torpedo anchor 100. One end of the working anchor chain 300 is connected to the torpedo anchor 100, and the other end is connected to a marine structure. On the one hand, after the torpedo anchor 100 penetrates into the deep sea, when it is necessary to retrieve the torpedo anchor 100, it can be retrieved through the working anchor chain 300. On the other hand, after the torpedo anchor 100 penetrates into the seabed, the two ends of the working anchor chain 300 are connected to the torpedo anchor 100 and the marine structure respectively, so that the marine structure can be moored on the sea surface.

[0048] The following explains how the drive unit 110 causes the main body 120 to rotate relative to the anchor wing 130. Please refer to... Figure 5 In some embodiments, the drive device 110 includes a torsion spring 111. The anchor wing 130 has a mounting hole 135, allowing it to be fitted onto the outside of the main body 120. The main body 120 has a storage cavity 121, in which the torsion spring 111 is disposed. One end of the torsion spring 111 is connected to the bottom wall of the storage cavity 121, and the other end is connected to the anchor wing 130. The torsion spring 111 can drive the main body 120 to rotate relative to the anchor wing 130. Specifically, the two ends of the torsion spring 111 are connected to the bottom wall of the storage cavity 121 and the anchor wing 130 respectively, thus enabling the torsion spring 111 to drive the main body 120 to rotate relative to the anchor wing 130. The torpedo anchor 100 also includes an anchor cover 140, which is connected to the main body 120 and closes the opening of the storage cavity 121 to protect the torsion spring 111.

[0049] The above describes the situation where the torsion spring 111 can drive the main body 120 to rotate relative to the anchor wing 130. It's conceivable that after the torsion spring 111 is twisted, it doesn't need to be immediately released to allow the main body 120 to rotate relative to the anchor wing 130. Therefore, the torsion spring 111 needs to maintain its torsional state after being twisted. The following explains how to maintain the torsion spring 111 in its torsional state; please refer to [reference needed]. Figure 5 , Figure 6 , Figure 7 and Figure 9In some embodiments, the torpedo anchor 100 abuts against the fixing plate 220, the fixing plate 220 having a locking pin 222 protruding from the surface of the fixing plate 220, and the main body 120 having a locking hole 122 at one end facing the fixing plate 220. When the torpedo anchor 100 is connected to the fixing plate 220 and together compresses the elastic member 210, the anchor wing 130 is disposed in the launching groove 233, and the locking pin 222 is disposed in the locking hole 122.

[0050] Specifically, when the anchor wing 130 is positioned in the launching groove 233, the launching groove 233 restricts the anchor wing 130 from rotating, allowing it to slide only. When the locking pin 222 of the fixing plate 220 is positioned behind the locking hole 122, and because the protrusion 221 of the fixing plate 220 is positioned in the fixing hole 232, the protrusion 221 can only slide, not rotate. Therefore, the locking pin 222 can only slide, not rotate. And since the locking pin 222 is positioned in the locking hole 122, it restricts the rotation of the locking hole 122, thus restricting the rotation of the main body 120. Specifically, the anchor wing 130 is restricted from rotating by the launching groove 233, and the main body 120 is restricted from rotating by the combined action of the locking pin 222 and the locking hole 122. Therefore, the main body 120 and the anchor wing 130 will not rotate relative to each other, and the torsion spring 111 can remain in a torsional state and cannot be released. Furthermore, after the torpedo anchor 100 is disengaged from the catapult assembly 200, the locking pin 222 disengages from the locking hole 122 and the anchor wing 130 disengages from the launch slot 233. At this time, the torsion spring 111 can drive the main body 120 to rotate relative to the anchor wing 130, thereby providing rotational power to the torpedo anchor 100.

[0051] The following describes the penetration and installation process of the torpedo anchor catapult device 10. The penetration and installation of the torpedo anchor catapult device 10 can be divided into three stages. Stage one: The torpedo anchor 100 is connected to the fixing plate 220, and the torpedo anchor 100 and the fixing plate 220 together compress the elastic element 210, while rotating the main body 120 or the anchor wing 130, causing the torsion spring 111 to be in a torsional state. At this time, the elastic element 210 is in a compressed state, awaiting reset; the torsion spring 111 is in a torsional state, awaiting reset; a portion of the torpedo anchor 100 is located in the launch chamber 231. Afterwards, the torpedo anchor catapult device 10 is launched into the sea.

[0052] Phase Two: When the torpedo anchor catapult device 10 falls into the deep sea and reaches the designed length of the installation anchor 400, the catapult assembly 200 stops falling. Meanwhile, the torpedo anchor 100, under the influence of gravity, disengages from the locking slot 234 and the anchor wing 130 and begins to fall. At this time, the elastic element 210 begins to reset, generating a downward thrust on the torpedo anchor 100, causing it to move and disengage from the catapult assembly 200. As the torpedo anchor 100 moves, the locking pin 222 disengages from the locking hole 122, the anchor wing 130 disengages from the launch slot 233, and the main body 120 rotates relative to the anchor wing 130. Furthermore, the torpedo anchor 100 continues to descend.

[0053] Phase Three: Under the action of the elastic element 210 and the torsion spring 111, the torpedo anchor 100 rapidly penetrates the seabed. During the penetration process, the main body 120 rotates and sinks until its energy is exhausted. The marine structure tightens the working anchor chain 300 connected to the main body 120, thus completing the penetration and installation of the torpedo anchor ejection device 10.

[0054] Please refer to Figure 5 In some embodiments, the drive device 110 further includes a bearing 112, with the inner ring of the bearing 112 fitted onto the main body 120 and the outer ring of the bearing 112 connected to the anchor wing 130. Specifically, by positioning the bearing 112 between the main body 120 and the anchor wing 130, the smoothness of rotation of the main body 120 relative to the anchor wing 130 can be improved. It is conceivable that there can be multiple bearings 112, which are spaced apart along the length of the main body 120.

[0055] The following explains how torsion spring 111 is connected to anchor wing 130. Please refer to... Figure 8 In some embodiments, the anchor wing 130 has a connecting block 131 and a mounting hole 135, which is fitted onto the main body 120. The connecting block 131 includes a first part 132 and a second part 133 that are connected to each other. The first part 132 extends along the center of the mounting hole 135, and the second part 133 extends axially relative to the mounting hole 135. The other end of the torsion spring 111 is connected to the second part 133. Specifically, after the connecting block 131 is connected to the anchor wing 130, the design of the first part 132 and the second part 133 allows one end of the torsion spring 111 to be connected to the anchor wing 130 without affecting the relative rotation of the main body 120 and the anchor wing 130.

[0056] Because the anchor wing 130 is equipped with a connecting block 131, when the torpedo anchor 100 abuts against the fixing plate 220, the blade 134 portion of the anchor wing 130 at the position corresponding to the connecting block 131 is blocked by the connecting block 131 and the fixing plate 220, and the blade 134 cannot be engaged in the slot 234. Therefore, please refer to... Figure 7 and Figure 8In some embodiments, the diameter of the fixing plate 220 is equal to the diameter of the mounting hole 135. The fixing plate 220 has a clearance hole 223. When the torpedo anchor 100 is connected to the fixing plate 220, the first part 132 passes through the clearance hole 223 so that the anchor wing 130 is engaged in the slot 234. Specifically, after the fixing plate 220 abuts against the torpedo anchor 100, the fixing plate 220 is housed in the storage cavity 121 of the main body 120. The clearance hole 223 makes way for the connecting block 131, so that the blade 134 at the position corresponding to the connecting block 131 can be engaged in the slot 234.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
