DETAILED DESCRIPTION

[0024] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0025] In the present disclosure, unless otherwise specified, the directional words such as "up", "down", "left", "right", etc. used to indicate the direction or position relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour.

[0026] In addition, "height direction" can be seen Figure 1 In the height direction shown. It should be noted that the terms "first," "second," and the like are used to distinguish one element from another and do not have a sequential or importance relationship. In the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.

[0027] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0028] refer to Figures 1 to 2 As described above, the present disclosure provides a suction anchor assembly 1, including a dry cabin 10, a plurality of connecting pipes 20 and a plurality of suction cylinders 30, each connecting pipe 20 is arranged in a one-to-one correspondence with each suction cylinder 30, one end of each connecting pipe 20 is connected to the dry cabin 10, and the other end of each connecting pipe 20 is connected to the suction cylinder 30 corresponding thereto; each suction cylinder 30 is detachably connected to the two suction cylinders 30 located on both sides thereof, and the plurality of suction cylinders 30 enclose a closed cylindrical space.

[0029] Through the above technical solution, the suction anchor assembly 1 provided by the present invention includes a plurality of detachably connected suction cylinders 30. On the one hand, with the joint cooperation of the plurality of suction cylinders 30, the bearing capacity and stability of the suction anchor assembly 1 can be improved. On the other hand, the use of a plurality of suction cylinders 30 as a fixed foundation for structures such as offshore wind power and offshore platforms can also reduce the size of a single suction cylinder 30 to a certain extent, thereby reducing the manufacturing difficulty and manufacturing cost of the suction cylinder 30, making it more convenient to lower the suction cylinder 30. Moreover, when sinking and installing a smaller suction cylinder 30, it can also effectively avoid the distortion and damage of the suction cylinder 30 due to excessive size, thereby further improving the stability of the suction cylinder 30 and the suction anchor assembly 1.

[0030] In addition, precisely because the multiple suction cylinders 30 are connected in a detachable manner, the carrying capacity of the suction anchor assembly 1 composed of the suction cylinders 30 can be adjusted by increasing or decreasing the number of suction cylinders 30, so as to match offshore platforms of different sizes and weights.

[0031] It should be noted that the dry tank 10 mentioned above may include an air pump assembly, which is connected to a plurality of connecting pipes 20 and can adjust the negative pressure in each suction cylinder 30 by suction, so that seawater can quickly enter the interior of the suction cylinder 30 under the action of the pressure difference.

[0032] The vacuum pump assembly disclosed herein may include multiple vacuum pumps, each of which may realize separate control of the pressure in each suction cylinder 30. In this way, during the descent of the suction anchor assembly 1, the vacuum pump assembly of the dry cabin 10 may also adaptively adjust the pressure of different suction cylinders 30 according to the sinking conditions of the multiple suction cylinders 30, thereby solving the tilting problem generated during the sinking of the suction cylinder 30 and the suction anchor assembly 1.

[0033] In order to facilitate the connection between adjacent suction anchors, in the present disclosure, as Figures 1 to 2As shown, the suction anchor assembly 1 may further include a plurality of connecting assemblies 40, with each suction cylinder 30 being provided with at least one connecting assembly 40, and two adjacent suction cylinders 30 being detachably connected via the connecting assembly 40. In this way, adjacent suction cylinders 30 can be assembled and disassembled via the connecting assembly 40, and since the connecting assembly 40 is provided independently of the suction cylinder 30, it is possible to prevent the structural strength of the suction cylinders 30 themselves from being affected during the connection process between the two adjacent suction cylinders 30.

[0034] Alternatively, in other embodiments provided in the present disclosure, the connecting component 40 may also be a part of the suction cylinder 30. In this way, on the one hand, the connecting component 40 and the suction cylinder 30 can have better structural consistency in parameters such as structural strength and density, thereby improving the stability and firmness of the connection between adjacent suction cylinders 30. On the other hand, the overall structure of the suction anchor assembly 1 can be simplified, making the connection between two adjacent suction cylinders 30 more compact.

[0035] The present disclosure does not limit the specific structure of the above-mentioned connecting component 40. For example, in an exemplary embodiment provided by the present disclosure, the connecting component 40 may include a connecting piece 41 and a connecting fitting piece 42. The connecting piece 41 and the connecting fitting piece 42 are both protruding from the outer wall of the suction cylinder 30. One of the two adjacent suction cylinders 30 is provided with a connecting piece 41, and the other of the two adjacent suction cylinders 30 is provided with a connecting fitting piece 42, and the connecting piece 41 is connected to the connecting fitting piece 42; or, one of the two adjacent suction cylinders 30 is provided with a connecting fitting piece 42, and the other of the two adjacent suction cylinders 30 is provided with a connecting piece 41, and the connecting fitting piece 42 is connected to the connecting piece 41. In this way, during the actual assembly process, the connecting piece 41 on one suction cylinder 30 can be clamped to the connecting fitting 42 on another suction cylinder 30 by hoisting, so as to realize the connection between the connecting piece 41 and the connecting fitting 42, thereby realizing the connection between the two suction cylinders 30. In addition, the installation method is simple and the installation difficulty is reduced (compared to the welding connection).

[0036] Alternatively, in another embodiment provided in the present disclosure, two adjacent suction cylinders 30 can also be connected by means of fasteners. For example, the above-mentioned suction anchor assembly 1 also includes a fastening bolt, a first mounting ear is provided on one suction cylinder 30, and a first mounting hole is formed on the first mounting ear, and a second mounting ear is provided on the other suction cylinder 30, and a second mounting hole is formed on the second mounting ear. The fastening bolt is sequentially passed through and locked in the first mounting hole and the second mounting hole, thereby achieving relative fixation between the two suction cylinders 30.

[0037] In an exemplary embodiment provided by the present disclosure, Figure 2 As shown, the above-mentioned connecting member 41 may include a large diameter section 411 and a small diameter section 412, the small diameter section 412 is connected between the large diameter section 411 and the suction cylinder 30, and the connecting fitting 42 is provided with a first engaging groove 421 and a second engaging groove 422 that are interconnected, the first engaging groove 421 is provided between the second engaging groove 422 and the suction cylinder 30, the first engaging groove 421 matches the shape of the large diameter section 411, and the second engaging groove 422 matches the shape of the small diameter section 412, the large diameter section 411 is engaged in the first engaging groove 421, and the small diameter section 412 is engaged in the second engaging groove 422. In this way, during the installation of two adjacent suction cylinders 30, by changing the positional relationship between the two suction cylinders 30, the large diameter section 411 can be engaged in the first engaging groove and the small diameter section 412 can be engaged in the second engaging groove. At this time, since the first engaging groove 421 is arranged between the second engaging groove 422 and the suction cylinder 30, the smaller second engaging groove 422 can serve as a stop for the larger large diameter section 411 engaged in the first engaging groove 421, thereby preventing the large diameter section 411 from detaching from the first engaging groove 421, thereby improving the stability of the cooperation between the connecting piece 41 and the connecting mating piece 42, so as to avoid relative displacement and loosening between the two adjacent suction cylinders 30.

[0038] In order to further improve the connection stability and firmness between two adjacent suction cylinders 30, as shown in FIG. Figure 2 As shown, optionally, there can be multiple connecting members 41 and multiple connecting fittings 42, and multiple connecting members 41 are spaced apart and arranged opposite each other along the height direction of the suction cylinder 30, and multiple connecting fittings 42 are spaced apart and arranged opposite each other. In this way, when assembling two adjacent suction cylinders 30, each connecting member 41 can be snapped into the corresponding connecting fitting 42 it faces, so that the multiple connecting members 41 and the multiple connecting fittings 42 respectively play a role in fixing and limiting the two suction cylinders 30 along the height direction of the suction cylinder 30.

[0039] Alternatively, as Figure 1 、 Figure 2 As shown, the dry tank 10 is disposed directly above the cylindrical space enclosed by a plurality of suction cylinders 30. The suction cylinders 30 on one side of the dry tank 10 are symmetrically arranged with respect to the suction cylinders 30 on the other side. Since the dry tank 10 is disposed above the plurality of suction cylinders 30, the operation of the dry tank 10 is not affected when the suction cylinders 30 are lowered.

[0040] Moreover, since the suction cylinder 30 located on one side of the dry tank 10 and the suction cylinder 30 located on the other side of the dry tank 10 are symmetrically arranged with respect to the dry tank 10, during the sinking process of the above-mentioned multiple suction cylinders 30, the weight of the suction anchor assembly 1 at different positions can be made more balanced, thereby avoiding the problem of the suction anchor assembly 1 tilting due to the uneven weight distribution of the suction cylinders 30 at different positions during the sinking process, and further improving the accuracy of the sinking process.

[0041] In addition, if Figures 1 to 2 As shown, the upper end of the suction cylinder 30 provided by the present disclosure has an upwardly open receiving cavity 33. Thus, after the suction anchor structure is lowered, the upwardly open receiving cavity 33 is designed to facilitate receiving fallen rocks, thereby increasing the overall weight of the suction anchor assembly 1 and further improving the load-bearing capacity of the suction anchor assembly 1.

[0042] Alternatively, as Figures 1 to 2 As shown, the suction cylinder 30 includes a main body 31 and an extension portion 32. The extension portion 32 is cylindrical, with the lower end of the extension portion 32 connected to the upper end of the main body 31 and the upper end of the extension portion 32 extending away from the main body 31. The upper end of the main body 31 and the extension portion 32 together form a receiving chamber 33. In other words, the extension portion 32 is formed above the main body 31, and the provision of the extension portion 32 does not affect or interfere with the normal sinking of the main body 31.

[0043] In an exemplary embodiment provided in the present disclosure, the main body 31 and the extension portion 32 may be integrally formed, which, on the one hand, facilitates the processing and manufacturing of the suction cylinder 30 , and on the other hand, enables the extension portion 32 and the main body 31 to have better connection strength.

[0044] Further, if Figure 1 As shown, the suction anchor assembly 1 may further include a plurality of lifting ears 50, each of which is used to connect to an anchor chain, and the lifting ears 50 are connected to the side wall of the suction cylinder 30. By installing a plurality of lifting ears 50 on the suction anchor assembly 1 to lead out a plurality of anchor chains, the suction anchor assembly 1 can provide greater pulling force.

[0045] In an embodiment in which there are multiple suction cylinders 30, each suction cylinder 30 can be connected to one of the above-mentioned lifting ears 50. In this way, the anchor chain can be drawn out from different suction cylinders 30 located in different directions and tension can be applied, so that the force on the suction anchor is more balanced.

[0046] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0048] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
