Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of offshore aquaculture equipment, and particularly relates to large-scale offshore aquaculture equipment convenient for rapid assembly and a method for assembling the same. BACKGROUND

[0002] With the continuous improvement of aquaculture technology and yield demand, the types of offshore aquaculture equipment are also increasing. Among them, the more common offshore aquaculture equipment is a culture net cage. This equipment is convenient to use, has large culture capacity, and can greatly meet market demand, and is therefore favored by the aquaculture industry. However, for the processing factory, the processing period is relatively long due to the large size of the culture net cage, and a large number of scaffolds need to be built during processing, which increases the overall production cost. At the same time, because of the need for continuous high-altitude work, there is also a high construction risk.

[0003] In order to solve the above problems, the Chinese invention patent with publication number CN110521649A discloses a deep-sea net cage aquaculture equipment infrastructure truss construction process. The truss is divided into three parts for separate construction, and then the three parts are folded together. The truss is an elliptical hollow structure connected by pipes, including a truss front section, a truss middle section, and a truss rear section. The truss front section and the truss rear section are symmetrically arranged at both ends of the truss middle section. The truss construction process is as follows: first, the truss front section, the truss middle section, and the truss rear section are separately manufactured, then the three sections are hoisted to the jig, and the truss front section, the truss middle section, and the truss rear section are folded into one whole body by installing bulk pipes. The advantages of the present application are that it can avoid continuous high-altitude work, achieve the purpose of safe production, and manufacture three parts separately. The three sections are combined into one, which can reduce the number of tooling pieces and scaffolds, reduce construction cost, shorten construction period, and improve construction efficiency.

[0004] However, in actual use, it is found that the scheme still has the following shortcomings:

[0005] 1) Although the truss is divided into three parts for processing in the preliminary preparation work, thereby avoiding the need for continuous high-altitude work in the early stage, the overall structure of the net cage is an olive ball structure, so the processing precision of the pipe material and the welding precision are required to be high, thereby indirectly increasing the processing period.

[0006] 2) After the three-section truss processing in the early stage is completed, the truss still needs to be hoisted and rotated by 90° to ensure that the axes of the three-section truss are perpendicular to the horizontal plane, and then the connection of the truss is welded in turn. This scheme not only cannot effectively save the processing period, but also increases the construction risk due to the continuous stacking of the truss in the vertical direction.

[0007] Therefore, it is necessary to design an offshore aquaculture equipment which is convenient to build and can avoid construction at a high altitude. SUMMARY

[0008] In order to overcome the defects of the prior art, the technical problem to be solved by the present application is how to provide a large-scale offshore aquaculture equipment which is convenient to build and can avoid construction at a too high height.

[0009] In order to solve the above technical problems, the technical scheme adopted by the present application is: a large-scale offshore aquaculture equipment convenient for rapid assembly, comprising a bottom cover piece, a middle piece and a top cover piece; the bottom cover piece, the middle piece and the top cover piece are all U-shaped structures; the bottom cover piece and the top cover piece are connected by two parallel middle pieces; the bottom cover piece, the middle piece and the top cover piece form a hollow columnar frame structure with a regular octagonal cross section; and the frame structure is provided with disc pieces at both ends.

[0010] Another technical scheme of the present application is: an assembly method of a large-scale offshore aquaculture equipment convenient for rapid assembly, the large-scale offshore aquaculture equipment comprising disc pieces, auxiliary support devices, and a bottom cover piece, a middle piece and a top cover piece composed of net cage pieces;

[0011] The assembly method comprises the following steps:

[0012] Installation of the bottom cover piece: along the axis direction of the aquaculture equipment, lay the net cage pieces on the horizontal plane as a reference surface; set the auxiliary support devices at the connection of the net cage pieces and on both sides in the axis direction of the aquaculture equipment; connect the net cage pieces on the reference surface, and continue to lay the net cage pieces on both sides in the axis direction of the aquaculture equipment, so that one side of the net cage pieces is connected with the net cage pieces on the reference surface, and the other side is leaned against the auxiliary support devices, thereby completing the installation of the bottom cover piece;

[0013] Installation of the top cover piece: repeat the installation of the bottom cover piece to obtain the top cover piece;

[0014] Installation of the middle piece: increase the height of the auxiliary support devices located on the outer side on the basis of the installation of the bottom cover piece; continue to lay the net cage pieces on both sides in the axis direction of the aquaculture equipment, so that one side of the net cage pieces is connected with the net cage pieces on both sides of the reference surface, and the other side is leaned against the auxiliary support devices, thereby completing the installation of the middle piece;

[0015] Assembly of the outer frame of the aquaculture equipment: on the basis that the installation of the bottom cover piece and the middle piece is completed, increase the height of the auxiliary support devices located on the inner side; hoist the top cover piece and flip it by 180° with the axis of the top cover piece as the rotation axis, and move it to the upper side of the bottom cover piece and the middle piece at the same time; lower the top cover piece until it is in contact with the auxiliary support devices, and then connect the top cover piece with the middle piece, thereby completing the assembly of the outer frame of the aquaculture equipment;

[0016] Assembling of the disc piece and the outer frame of the culture equipment: after the outer frame of the culture equipment is assembled, the disc piece is hoisted; the disc piece is close to one end of the outer frame of the culture equipment, until the disc piece and the net cage piece on the outer frame of the culture equipment coincide with each other, then the disc piece is connected with the outer frame of the culture equipment, and the above operation is repeated at the other end of the outer frame of the culture equipment, so that the assembling work of the culture equipment is completed.

[0017] The large-scale offshore culture equipment convenient for rapid assembly and the assembling method thereof have the advantages that the large-scale offshore culture equipment convenient for rapid assembly and the assembling method thereof are simple in structure and convenient to use, the offshore culture equipment is divided into three piece structures along the radial direction, and the piece structures are all composed of planes, so that the construction period can be shortened in the preparation stage, and the construction height can be reduced and the safety of construction can be improved.

[0028] To describe the technical contents of the present application, the purposes and effects achieved, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0029] The most key idea of the present application is that the offshore aquaculture equipment is divided into three segmental plate structures along the radial direction, which provides a basis for the construction scheme of the aquaculture equipment in the horizontal direction, so as to improve the construction efficiency and effectively reduce the construction height, thereby improving the safety of the construction.

[0030] Please refer to Figures 1 to 4 The large offshore aquaculture equipment provided by the present application comprises a bottom cover segment 4, a middle segment 5 and a top cover segment 6; the bottom cover segment 4 and the top cover segment 6 are both U-shaped structures; the bottom cover segment 4 and the top cover segment 6 are connected through two parallel middle segments 5; the bottom cover segment 4, the top cover segment 6 and the middle segments 5 form a hollow columnar frame structure with a regular octagonal cross section; and the frame structure is provided with disc segments 2 at both ends.

[0031] From the above description, the beneficial effects of the present application are that a large offshore aquaculture equipment is provided, which is divided into three segmental plate structures along the radial direction, and the plate structures are all composed of planes, so that not only efficient and automatic production can be realized in the preparation stage, but also the aquaculture equipment can be constructed in the horizontal direction, i.e. the final forming state of the aquaculture equipment is the axial horizontal state; the device has a simple structure and is easy to operate, and compared with the existing aquaculture equipment, the device can effectively shorten the processing period and significantly reduce the construction height, thereby improving the safety of the construction.

[0032] Further, the bottom cover segment 4, the top cover segment 6 and the middle segments 5 are all composed of net cage segments 1; the net cage segment 1 comprises at least two units; each unit comprises two first tubular materials 11 with parallel axes, and a second tubular material 12 connected to the two first tubular materials 11 at both ends and having an axis perpendicular to the axes of the first tubular materials 11; and the opposite corners of the rectangular frame formed by the first tubular material 11 and the second tubular material 12 are connected through reinforcing pipes 13.

[0033] From the above description, the net cage segment 1 is the smallest unit of the bottom cover segment 4, the top cover segment 6 and the middle segments 5, so the designer can change the connection angle of the net cage segment 1 to change the cross-sectional shape of the frame structure, thereby improving the structural diversity of the aquaculture equipment to adapt to various aquaculture needs.

[0034] Further, the periphery of the disc segment 2 is provided with a connecting frame 21 corresponding to the frame structure formed by the bottom cover segment 4, the top cover segment 6 and the middle segments 5; and the connecting frame 21 is connected to the disc segment 2 through radial reinforcing ribs 22.

[0035] From the above description, the design can further close the two ends of the aquaculture equipment after the wide body structure of the aquaculture equipment is built, so as to form a relatively closed space and provide a basis for subsequent aquaculture work.

[0036] Further, the center of the disc piece 2 is provided with a motor positioning sleeve 23.

[0037] From the above description, the design can facilitate the positioning and fixing of the disc piece 2 and the motor, thereby providing a basic guarantee for the subsequent rotation function of the aquaculture equipment around its axis.

[0038] Further, the disc piece 2 has a zinc block 24 evenly distributed in the circumferential surface of the disc piece 2 with the axis of the disc piece 2 as the rotation axis.

[0039] From the above description, since the aquaculture equipment needs to be soaked in corrosive seawater for a long time, the corrosion of the aquaculture equipment can be alleviated by setting the corrosion-resistant zinc block 24 on the disc piece 2, thereby improving the overall service life.

[0040] Further, the materials of the bottom cover piece 4, the top cover piece 6, the middle section piece 5 and the disc piece 2 are all steel.

[0041] From the above description, since the marine environment is complex, the use of steel structure to build the aquaculture equipment can improve the overall strength and avoid economic losses caused by structural damage.

[0042] Further, it also includes an auxiliary support device 3, which includes a height adjusting frame 31 and a support piece 32; the support piece 32 is arranged at any one end of the height adjusting frame 31, and is coaxially arranged with the height adjusting frame 31; during construction, the auxiliary support device 3 is arranged at the connection of the net cage piece 1, and the support piece 32 is in contact with the side wall of the first pipe 11, the second pipe 12 or the reinforcing pipe 13. Preferably, the height adjusting device can be a stacked square steel frame structure, and the height can be adjusted by stacking different numbers; the height adjusting device can also be any device that can automatically change the stroke, such as a pneumatic cylinder.

[0043] From the above description, the auxiliary support device 3 can provide support during the construction of the aquaculture equipment, which not only saves the time and cost of building scaffolding, but also effectively changes the traditional construction scheme of ensuring that the axis of the aquaculture equipment is perpendicular to the horizontal plane into a new construction scheme of making the axis of the aquaculture equipment parallel to the horizontal plane, thereby significantly reducing the overall construction height and improving the safety of the construction.

[0044] Further, the support 32 comprises a square tube 321 and a limiting code plate 322; one end of the square tube 321 is connected with the height adjusting frame 31, and the other end is connected with the limiting code plate 322; the square tube 321 is coaxially arranged with the height adjusting frame 31; the code plate is provided with an arc-shaped concave surface 3221 at the end away from the square tube 321.

[0045] From the above description, it can be known that the design can further improve the supporting effect of the auxiliary support device 3; by arranging the arc-shaped concave surface 3221 on the limiting code plate 322, the net cage piece body 1 can be limited during the supporting process, so as to avoid violent shaking during the erection process, thereby avoiding unnecessary damage.

[0046] Further, the assembling method of the large-scale offshore aquaculture equipment is characterized in that the large-scale offshore aquaculture equipment comprises a disc piece body 2, an auxiliary support device 3, and a bottom cover piece body 4, a top cover piece body 6 and a middle section piece body 5 composed of the net cage piece body 1;

[0049] Installation of the top cover piece body 6: the installation of the bottom cover piece body 4 is repeated to obtain the top cover piece body 6;

[0050] Installation of the middle section piece body 5: based on the bottom cover piece body 4, the height of the auxiliary support device 3 located on the outer side is increased; the net cage piece body 1 is continuously laid on both sides of the axis direction of the aquaculture equipment, so that one side of the net cage piece body 1 is connected with the net cage piece body 1 on both sides of the base surface, and the other side is leaned against the auxiliary support device 2, thereby completing the installation of the middle section piece body 5;

[0051] Assembling of the outer frame of the aquaculture equipment: based on the completion of the installation of the bottom cover piece body 4 and the middle section piece body 5, the height of the auxiliary support device 2 located on the inner side is increased; the top cover piece body 6 is lifted and flipped by 180° with the axis of the top cover piece body 6 as the rotating shaft, and is moved to the upper side of the bottom cover piece body 4 and the middle section piece body 5; the top cover piece body 6 is lowered until it is in contact with the auxiliary support device 2, and then the top cover piece body 6 is connected with the middle section piece body 5, thereby completing the assembling of the outer frame of the aquaculture equipment;

[0052] Assembling the disc piece 2 and the outer frame of the culture equipment: after the outer frame of the culture equipment is assembled, the disc piece 2 is hoisted; the disc piece 2 is close to one end of the outer frame of the culture equipment, until the disc piece 2 and the net cage piece 1 on the outer frame of the culture equipment coincide with each other, then the disc piece 2 is connected with the outer frame of the culture equipment, and the above operation is repeated at the other end of the outer frame of the culture equipment, thereby completing the assembly of the culture equipment.
