[0032] Moving the mat structure to below the corresponding middle section of the column;

[0033] Lowering the upper structure of the net cage so that the middle section of the column rests on the lower section of the column, and fixedly connecting the middle section of the column with the lower section of the column;

[0042] It can be seen from the above technical solution that the advantages and positive effects of the present invention are:

[0043] The deep-sea aquaculture cage of the present invention comprises columns divided into upper, middle, and lower sections. The upper sections, together with the upper horizontal tube, form the cage's upper structure, while the lower sections, together with the submerged mat, form the submerged mat structure. This allows for vertical loading from top to bottom. Furthermore, the deep-sea aquaculture cage is loaded vertically from top to bottom by docking the upper and middle sections of the columns, and then docking the middle and lower sections. This reduces overhead work and increases precision.

[0044] The deep-sea aquaculture cage installation method involves first assembling the cage's upper structure, then connecting the midsections of the columns to the cage's upper structure, and then connecting the submerged structure to the midsections of the columns. The entire process is performed on the ground before lifting, ensuring that the assembly process is performed on the ground or at a low altitude as much as possible, reducing overhead work and minimizing risks. Since most of the work is done on the ground or at a low altitude, the operational difficulty is reduced, the construction period of the deep-sea aquaculture cage is shortened, and efficiency is greatly improved.

[0045] At the same time, since the deep-sea aquaculture cage is equipped with simple equipment and does not require a large gantry crane, the selection of construction sites is wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0057] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0058] The present invention provides a deep-sea aquaculture cage and a method for loading the deep-sea aquaculture cage. Due to the structure of the deep-sea aquaculture cage, it can be loaded step by step from top to bottom, converting high-altitude operations into operations on the ground. Therefore, there are fewer high-altitude operations and lower risks.

[0059] Figure 1 Shows a schematic diagram of the structure of deep-sea aquaculture cages, see Figure 1 The deep-sea aquaculture cage 1 is a truss cage, which includes a cage upper structure 11, a middle section of a column 12, a lower horizontal pipe 14, a diagonal brace 15 and a cushion structure 13.

[0060] Figure 2 The schematic diagram of the structure of the upper structure 11 of the cage is shown. Figure 2 The upper structure 11 of the cage includes multiple upper column sections 112, multiple upper horizontal tubes 113 and a living area structure 117.

[0061] In this embodiment, the deep-sea aquaculture cage 1 has a square cross-section. Therefore, there are four column upper sections 112, located at the four corners. In other embodiments, the deep-sea aquaculture cage 1 can also have a circular cross-section, with multiple column upper sections 112 spaced circumferentially. The deep-sea aquaculture cage 1 can also have other polygonal cross-sections, with the column upper sections 112 located at the corners of the polygonal structure.

[0062] An upper horizontal tube 113 is installed above the upper column sections 112, forming the cage's upper ring. Specifically, there are four upper horizontal tubes 113, one installed between any two adjacent upper column sections 112. In this embodiment, the deep-sea aquaculture cage 1 has a square cross-section, so both the upper ring and the cage superstructure 11 are square.

[0063] The upper portion of the upper ring is provided with a living area structure 117. Specifically in this embodiment, the living area structure 117 is located at the upper section 112 of one of the columns.

[0064] A mechanical area structure 118 is further provided on the upper portion of the upper ring, and is disposed opposite the living area structure 117. In this embodiment, the mechanical area structure 118 and the living area structure 117 are located on the diagonal line of the cage upper structure 11, so that the load distribution of the cage upper structure 11 is more uniform.

[0065] Preferably, the cage upper structure 11 is divided into a plurality of independent cage upper units 111, which are assembled to form the cage upper structure 11. Specifically, the upper horizontal pipe 113 includes two pipe segments 1131, and the two pipe segments 1131 correspond to the two column upper sections 112, respectively. The structure consisting of the column upper sections 112 and the pipe segments 1131 mounted on the columns is defined as the cage upper unit 111. That is, each cage upper unit 111 includes a column upper section 112 and a pipe segment 1131 mounted on the column upper section 112.

[0066] In this embodiment, the cross-section of the cage upper structure 11 is square, so there are four cage upper units 111, each of which includes an upper column section 112, a pipe section 1131 extending longitudinally, and a pipe section 1131 extending transversely.

[0067] Each upper unit 111 of the net cage is connected to the pipe section 1131 of the adjacent upper unit 111 of the net cage by docking the pipe section 1131 , and the two docked pipe sections 1131 constitute the upper horizontal pipe 113 .

[0068] Dividing the upper horizontal pipe 113 into shorter pipe segments 1131 facilitates assembly and transportation of the upper cage unit 111. Specifically, the upper cage unit 111 can be fabricated in a workshop or factory, then transported to a workspace and butt-welded to form the assembled upper cage structure 11.

[0069] Furthermore, the cage superstructure 11 includes a plurality of middle horizontal tubes 114. These tubes 114 correspond one to one with the upper horizontal tubes 113, with each tube 114 positioned below the upper horizontal tubes 113. The tubes 114 are positioned below the upper column sections 112 to form the cage's center ring.

[0070] The middle horizontal tube 114 has the same structure as the upper horizontal tube 113 and is also formed by connecting the tube sections respectively provided on the upper sections 112 of the two columns. For details, please refer to the description of the upper horizontal tube 113 .

[0071] Therefore, the upper unit 111 of the cage in this embodiment includes an upper column section 112 and four pipe sections, two of which extend longitudinally, two extend transversely, the two longitudinally extending pipe sections are spaced apart vertically, and the two transversely extending pipe sections are spaced apart vertically.

[0072] Furthermore, a plurality of connecting rods 115 are provided between the upper horizontal tube 113 and the middle horizontal tube 114 , and each connecting rod 115 is arranged at an angle to enhance the strength of the entire cage upper structure 11 .

[0073] Each cage upper unit 111 includes a plurality of connecting rods 115 .

[0074] A reinforcing rod 116 is further provided between any two adjacent upper horizontal tubes 113 to enhance the strength of the upper ring.

[0075] The plurality of column middle sections 12 are arranged in a one-to-one correspondence with the plurality of column upper sections 112. Each column middle section 12 is located at the bottom of the corresponding column upper section 112.

[0076] Multiple mat structures 13 are used to support the entire deep-sea aquaculture cage 1. These mat structures 13 are arranged one-to-one with the multiple column middle sections 12. Each mat structure 13 includes a mat 131 and a column lower section 132 inserted within the mat 131. The column lower section 132 extends upward beyond the mat 131. Each column lower section 132 is located at the bottom of the corresponding column upper section 112.

[0077] A plurality of lower horizontal tubes 14 are connected to the lower portion of the column middle section 12. The lower horizontal tubes 14 are arranged in a one-to-one correspondence with the upper horizontal tubes 113, and the lower horizontal tubes 14 are arranged parallel to and spaced apart from the corresponding upper horizontal tubes 113.

[0078] There are multiple diagonal braces 15. Each diagonal brace 15 obliquely connects the lower horizontal pipe 14 and the cage upper structure 11. Specifically in this embodiment, the two ends of the diagonal brace 15 are connected to the lower horizontal pipe 14 and the middle horizontal pipe 114 respectively.

[0079] The height of the deep-sea aquaculture cage 1 in the present application is greater than or equal to 40 meters, that is, the sum of the axial lengths of the upper column section 112, the middle column section 12 and the lower column section 132 is greater than or equal to 40 meters, and the axial length of the middle column section 12 is greater than the axial length of the upper column section 112, and the axial length of the middle column section 12 is greater than the axial length of the lower column section 132.

[0080] Preferably, the axial length of the upper column section 112 is greater than or equal to 5 meters. The height of the lower column section 132 extending upwards from the mat 131 is greater than or equal to 1 meter.

[0081] The deep-sea aquaculture cage 1 is structured such that the columns are divided into an upper column section 112, a middle column section 12, and a lower column section 132. The upper column section 112 and an upper horizontal tube 113 form a cage upper structure 11, while the lower column section 132 and a submerged pad 131 form a submerged pad structure 13, thereby enabling the cage to be loaded vertically from top to bottom. Furthermore, the deep-sea aquaculture cage 1 is loaded vertically from top to bottom by connecting the upper column section 112 with the middle column section 12, and then connecting the middle column section 12 with the lower column section 132. This reduces the need for high-altitude work and improves accuracy.

[0082] The following specifically introduces the method for mounting the deep-sea aquaculture cage 1, which includes the following steps:

[0083] S1. Install multiple tower cranes 2 at preset positions, so that the multiple tower cranes 2 correspond to the columns of the deep-sea aquaculture cages 1 respectively; the multiple tower cranes 2 enclose a working space.

[0084] Specifically, the height of the tower crane 2 is greater than the height of the entire deep-sea aquaculture cage 1 .

[0085] When the deep-sea aquaculture cage 1 is square, there are four tower cranes 2, which are arranged at the four corners. When the deep-sea aquaculture cage 1 is in other shapes, the multiple tower cranes 2 are arranged in a one-to-one correspondence with the multiple columns of the deep-sea aquaculture cage 1.

[0086] S2. Assemble the upper section of the column 112, the pipe section and the living area structure 117 to obtain the cage upper structure 11.

[0087] The assembly method of the cage upper structure 11 is as follows:

[0088] The upper section 112 of each column is connected to at least two pipe sections to assemble into an upper unit 111 of the cage. The at least two pipe sections extend horizontally and are arranged on different sides of the column.

[0089] Specifically, the two pipe sections are fixed on the same side of the upper section 112 of the column at an interval in the vertical direction, and the two pipe sections are arranged in parallel.

[0090] In this embodiment, two longitudinal pipe sections and two transverse pipe sections are welded to the upper column section 112. The two longitudinal pipe sections are spaced apart vertically, and the two transverse pipe sections are spaced apart vertically.

[0091] Furthermore, a plurality of inclined connecting rods 115 are fixed between the two pipe sections vertically spaced apart.

[0092] That is, a plurality of connecting rods 115 are fixed between two longitudinal pipe sections, and a plurality of connecting rods 115 are fixed between two transverse pipe sections.

[0093] A plurality of net cage upper units 111 are transported into the working space, and any two adjacent net cage upper units 111 are connected by butting pipe sections together to form a net cage upper structure 11 .

[0094] Before the upper units 111 of the net cages are connected, a living area structure 117 and a mechanical area structure 118 are fixed on the tops of the two oppositely arranged upper units 111.

[0095] S3. Connect the cage upper structure 11 in the working space to the tower crane 2 and lift it to a first preset height via the tower crane 2.

[0096] Specifically, the oil cylinder on the tower crane 2 is connected to the lifting lug on the net cage upper structure 11. The oil cylinder brings the net cage upper structure 11 up.

[0097] The first preset height enables the bottom of the cage upper structure 11 to be off the ground, and the height difference between the bottom of the cage upper structure 11 and the ground is greater than or equal to the diameter of the middle section 12 of the column.

[0098] S4. Hingedly connect one end of the middle section 12 of the column of the deep-sea aquaculture cage 1 to the bottom of the upper section 112 of the column.

[0099] Specifically, one end of the middle column section 12 is hingedly connected to the bottom of the upper column section 112 , and the other end is located on and connected to the sliding device.

[0100] In this embodiment, after the column middle section 12 is placed on the sliding device, the column middle section 12 extends horizontally, that is, the first preset height is equal to the sum of the height of the sliding device and the diameter of the column middle section 12 .

[0101] In other embodiments, the middle section 12 of the column may also be slightly inclined.

[0102] S5. Continue to lift the upper structure 11 of the cage to a second preset height by the tower crane 2, and erect the middle section of the column 12.

[0103] Specifically, the oil cylinder on the tower crane 2 continues to drive the cage upper structure 11 to rise, and during the rising process, the end of the column middle section 12 close to the cage upper structure 11 is gradually lifted upward, and the other end located on the sliding device approaches the cage upper structure 11 along with the sliding device until the column middle section 12 is erected, and then the connection between the column middle section 12 and the sliding device is released.

[0104] S6. Fix the middle section 12 of the column to the upper section 112 of the column.

[0105] Specifically, between the fixed column middle section 12 and the column upper section 112 , the column middle section 12 is adjusted to extend vertically.

[0106] In this embodiment, the middle sections 12 of the two columns are connected by a steel wire rope, and the steel wire rope is dragged toward the middle so that the middle sections 12 of the columns are perpendicular to the baseline. The baseline is located on the ground and extends in the horizontal direction.

[0107] After the vertical extension of the middle section 12 of the column is adjusted, the middle section 12 of the column and the upper section 112 of the column are welded and fixed.

[0108] S7. Combine the cushion 131 and the lower section of the column 132 to obtain the cushion structure 13.

[0109] Specifically, the lower section 132 of the column is inserted into the sinking pad 131 , and the lower section 132 of the column and the sinking pad 131 are welded and fixed.

[0110] S8. Lift and adjust the cage upper structure 11 to the installation height, and fix the cushion structure 13 below the column middle section 12. The installation height is greater than the second preset height, the second preset height is greater than the first preset height, and the first preset height is greater than the diameter of the column middle section 12.

[0111] The steps of lifting and adjusting the upper structure 11 of the cage to reach the installation height and fixing the cushion structure 13 below the middle section 12 of the column include:

[0112] S81. Lift the upper structure 11 of the cage to a third preset height, which is greater than the installation height.

[0113] That is, by lifting the upper structure 11 of the cage, the distance between the bottom of the middle section 12 of the column and the ground is made greater than the height of the mat structure 13, so that the mat structure 13 can enter the working space more easily.

[0114] S82, move the cushion structure 13 to below the corresponding column middle section 12.

[0115] The mat structure 13 is placed at a preset position so as to be located below the corresponding column middle section 12 .

[0116] S83, lower the upper structure 11 of the net cage so that the middle section 12 of the column falls on the lower section 132 of the column, and fix the middle section 12 of the column to the lower section 132 of the column.

[0117] The oil cylinder drives the upper structure 11 of the net cage and the middle section 12 of the column to descend, so that the middle section 12 of the column falls onto the lower section 132 of the column.

[0118] S9. Install the lower horizontal pipe 14 between the lower parts of the middle sections 12 of the multiple columns, and install the diagonal brace 15 between the lower horizontal pipe 14 and the upper structure 11 of the cage to complete the loading.

[0119] Specifically, after the diagonal brace 15 is fixed, it is repaired with paint and then the mesh is hung after inspection.

[0120] Among them, step S1 and step S2 can be performed simultaneously to save time and shorten the construction period.

[0121] The method for mounting the deep-sea aquaculture cage 1 includes first assembling the cage upper structure 11, then connecting the column middle section 12 to the cage upper structure 11, and then connecting the submerged structure 13 to the column middle section 12. The entire process is performed on the ground before being lifted off the ground. The assembly process is performed on the ground or at a low altitude as much as possible, reducing overhead work and lowering risks. Since most of the work is done on the ground or at a low altitude, the operational difficulty is reduced, the construction period of the deep-sea aquaculture cage 1 is shortened, and efficiency is greatly improved.

[0122] At the same time, since the deep-sea aquaculture cage 1 is equipped with simple equipment and does not require a large gantry crane, the choice of construction sites is wider. Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
