Description

[0002] At present, the exploitation of marine resources enters the field of ultra-deep water of 3000 meters, and marine floating structures such as offshore drilling platforms, floating production storage and offloading devices are essential facilities for marine resource exploitation. As an important part of the marine floating structure, the wave absorbing system greatly increases the construction cost and construction difficulty with the increase of the scale and water depth of the marine floating structure. Compared with the traditional anchoring structure, the torpedo anchor is simple and quick to install, does not need a launching device to provide power, and can be installed by free falling relying on gravity only, which is theoretically applicable to any water depth. The torpedo anchor generally has a shape similar to a torpedo, including a body, a wing and a head, the body is cylindrical, the head is arranged at the front end of the body, and the wing is arranged on the outer circumferential surface of the body along the length direction of the body. The tail end of the body is connected with an installation anchor chain and a working anchor chain. The existing torpedo anchor is transported to the designated installation position by an anchor boat, then the torpedo anchor is vertically hung above the sea bed surface through the installation anchor chain, and then the installation anchor chain is released to make the torpedo anchor fall freely. After the torpedo anchor penetrates into the seabed, the working anchor chain is tensioned, and the installation of the torpedo anchor is completed.

[0047] Reference Figures 1 to 5 The present application proposes a deep-sea torpedo anchor construction device 100, comprising:

[0048] A hoisting mechanism 10, the hoisting mechanism 10 is located on the sea surface;

[0049] A guide mechanism 20 is located between the hoisting mechanism 10 and the seabed and is connected with the hoisting mechanism 10, a guide track (not shown) is formed between the top end and the bottom end of the guide mechanism 20 and is used for accommodating the torpedo anchor 300; and

[0050] A mounting anchor chain 30 is telescopically wound on the hoisting mechanism 10, and a movable end of the mounting anchor chain 30 extends into the guide track from the top end of the guide mechanism 20 and is used for connecting the torpedo anchor 300 in the guide track to limit the depth of the torpedo anchor 300 extending into the guide track.

[0051] The deep-sea torpedo anchor construction device 100 of the technical scheme of the present application comprises the hoisting mechanism 10, the guide mechanism 20 and the mounting anchor chain 30, wherein the guide mechanism 20 is located between the sea surface and the seabed, a guide track is formed between the top end and the bottom end of the guide mechanism 20 and is adapted to the torpedo anchor 300 and is used for accommodating the torpedo anchor 300, and the movable end of the mounting anchor chain 30 is connected with the torpedo anchor 300 in the guide track to limit the depth of the torpedo anchor 300 extending into the guide track. Before the torpedo anchor 300 is penetrated, the mounting anchor chain 30 is disconnected, the torpedo anchor 300 makes free fall along the guide track, the guide track isolates the environmental load received by the torpedo anchor 300 during falling outside the guide mechanism 20, reduces the influence of the environmental load on the penetration angle and the penetration point of the torpedo anchor 300, and makes the torpedo anchor 300 achieve the preset installation effect and improve the load bearing performance after the torpedo anchor 300 is installed.

[0052] The hoisting mechanism 10 further comprises a mounting anchor winch 11, and the mounting anchor chain 30 is telescopically wound in the mounting anchor winch 11. The deep-sea torpedo anchor construction device 100 further comprises a wireless remote control cutting clamp (not shown) arranged on the mounting anchor chain 30, and the mounting anchor chain 30 can be cut off by remote control.

[0053] Reference Figures 1 to 2 In an embodiment of the present application, the guide mechanism 20 comprises a plurality of guide pipes 21, channels (not shown) are formed in the two ends of the guide pipes 21 arranged oppositely, and the guide pipes 21 are sequentially connected end to end to form the guide mechanism 20, so that the channels are connected to form the guide track.

[0054] In the technical scheme of the embodiment of the present application, the guide mechanism 20 comprises a plurality of guide pipes 21, the guide pipes 21 are internally formed with through channels, and the plurality of guide pipes 21 are spliced end to end to form the guide mechanism 20. According to the size of the torpedo anchor 300 and real-time environmental load and other factors, the plurality of guide pipes 21 are spliced into the guide mechanism 20 with a preset length, then the guide mechanism 20 is lowered from the sea surface by the hoisting mechanism 10 and hung above the seabed, after the guide mechanism 20 is stable, the anchor chain 30 is disconnected, so that the torpedo anchor 300 is free falling and penetrates into the seabed.

[0055] Since the long guide mechanism 20 has problems in transportation, storage and installation on the anchor laying ship 200, the guide pipes 21 which can be spliced into the guide mechanism 20 in real time can not only reduce the transportation cost, but also fully utilize the storage space. The deep sea torpedo anchor construction device 100 further comprises an assembling mechanism for assembling the guide pipes 21 into the guide mechanism 20. When the guide pipes 21 are spliced, the hoisting mechanism 10 sinks one end of the plurality of spliced guide mechanisms 20 into the sea and exposes the other end of the guide mechanism 20 on the sea surface, the assembling mechanism hoists and transports the guide pipes 21 to be spliced to the sea surface, the guide pipes 21 to be spliced and the spliced guide mechanism 20 are connected by a locking piece (not shown), when the guide mechanism 20 reaches the preset depth, the assembling mechanism stops splicing, and the guide mechanism 20 is lowered to the preset depth when the hoisting mechanism 10 is lowered; when the guide mechanism 20 does not reach the preset depth, the assembling mechanism continues to splice. The design that the guide mechanism 20 is spliced by the guide pipes 21 reduces the transportation cost, fully utilizes the storage space of the anchor laying ship 200, and can customize the length of the guide mechanism 20 according to actual needs, thereby improving the applicability of the guide mechanism 20 in various environments.

[0056] When the torpedo anchor 300 is free falling in the channel, the environmental load is rejected outside the guide pipe 21 and cannot act on the torpedo anchor 300 inside the guide pipe 21, so that the arrangement of the guide pipe 21 reduces the influence of the environmental load on the installation of the torpedo anchor 300 and improves the load bearing performance of the torpedo anchor 300 after installation.

[0057] Reference Figures 1 to 2 In the embodiment of the present application, the guide pipe 21 comprises:

After the splicing is completed, the torpedo anchor 300 is placed in the channel of the uppermost conduit 21, the anchor chain 30 is cut off, and then the torpedo anchor 300 is free-falling and sequentially passes through a plurality of channels, and finally leaves the channel from the channel of the lowermost conduit 21 and penetrates into the soil layer of the seabed. The arrangement of the connecting portion 211 improves the stability of the structure of the guiding mechanism 20.

[0064] In the technical scheme of one embodiment of the present application, the torpedo anchor 300 is placed in the channel through the through hole 2111, the anchor chain 30 is arranged in the through hole 2111 and connected with the torpedo anchor 300. Since the torpedo anchor 300 comprises three parts of the anchor body 310, the anchor wing 320 and the anchor head 330, the anchor wing 320 is arranged on the outer periphery of the anchor body 310, so that the outer periphery of the torpedo anchor 300 is uneven. In order to limit the angle of the torpedo anchor 300 entering the channel and make the torpedo anchor 300 reach the predetermined penetration depth and penetration angle, a plurality of wing holes 2112 connected with the through hole 2111 are further arranged on the connecting portion 211. Only when the anchor wing 320 of the torpedo anchor 300 is aligned with the wing hole 2112, the torpedo anchor 300 can be placed in the channel, at this time, the angle of the torpedo anchor 300 entering the channel is the preset angle, and the accuracy of the installation of the torpedo anchor 300 is improved.

The plurality of guide grooves 2121 are arranged at intervals along the circumferential direction of the main body 212, and the guide grooves 2121 are used to limit the angle at which the torpedo anchor 300 leaves the guide rail.

When the hoisting mechanism 10 lowers the guide mechanism 20, the torpedo anchor 300 and the limiting plate 23 are tightly pressed against each other to pull out the anchor chain 30 from the anchor installation machine 11 on the anchor throwing ship 200. The arrangement of the limiting plate 23 improves the stability of the deep-sea torpedo anchor construction device 100, avoids the torpedo anchor 300 from leaving the guide rail during construction, and causes the torpedo anchor 300 to be unable to normally penetrate into the seabed.
