Description

Technical Field

[0001] The present invention relates to the field of floating wind turbine mounting construction technology, and in particular to a mounting and folding technology for a wind-solar-fishery integrated offshore floating wind turbine. Background Art

[0002] At present, in the field of offshore wind power, floating wind turbines have received extensive attention as important equipment for the development of offshore wind power, and have been put into commercial production. Deep sea and large-scale are the main directions of the current development of offshore wind power. The sea has rich wind energy resources, vast marine fish, and marine ranches. It is of great significance to develop integrated floating wind turbines that integrate wind energy, solar energy and marine ranches.

[0003] At present, there are a number of wind, solar and fishery integrated floating wind turbines, such as Figure 1 As shown, it includes three bottom sway control tanks and three columns. The three columns are respectively arranged on the top surfaces of the three bottom sway control tanks to form three floating bodies. The three floating bodies are connected by horizontal braces and diagonal braces to form a whole. The fusion floating wind turbine foundation is composed of non-standardized large-sized components due to the huge size of each bottom sway control tank and column. The production, manufacturing, welding and assembly of these non-standardized large-sized components require a lot of production time and production costs, and have extremely high requirements for the production, manufacturing, welding and assembly sites.

[0004] Therefore, the present invention proposes a mounting and folding technology for a wind-solar-fishery integrated offshore floating wind turbine to solve the above-mentioned problem. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a mounting and folding technology for a wind-solar-fishing integrated offshore floating wind turbine, reduce the manufacturing difficulty and site requirements, and improve the mounting speed and mounting accuracy.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a technology for mounting and closing a wind, solar and fishery integrated offshore floating wind turbine, the wind, solar and fishery integrated floating wind turbine includes three triangularly distributed floating bodies, each of which includes a bottom sway control cabin and a column located above the bottom sway control cabin, and the three floating bodies are connected by three cross beams to form a whole, and its innovation lies in: the mounting technology includes two stages, namely Phase 1: Construction in sections; Construction of the bottom sway control cabin: the bottom sway control cabin is divided into five sections, and the five sections are constructed separately on the platform. The five sections include a disc section and four arc sections. When the disc section is constructed separately, the upper top plate is used as the base surface for reverse construction, and the internal components and the ring plate are installed in sequence. The lower bottom plate is turned over and covered and then formed as a whole. The disc section is turned over and in a normal state. When constructing, each arc section is constructed as the base surface for positive construction. After the internal components and the ring plate are installed on the lower bottom plate, the upper bottom plate is finally buckled. After the four arc sections are constructed separately, a transition connection cone head is installed on two adjacent arc sections respectively. After all the five sections are constructed separately, they are hoisted to the outside field for closing. The four arc sections are spliced ​​together into a circular ring and arranged around the disc section. After the assembly is completed, the bottom sway control cabin is formed; Column construction: The columns are divided into three sections, which are built separately on the platform. The three sections are the bottom column, the second-layer column and the top column deck. When each section is built, the watertight platform is used as the base surface of the frame to build the wall plate and the internal bulkhead plate. When the top column deck is built, two transition connection cones need to be installed on the wall plate of the top vertical plate deck. After all three sections are built separately, they are sandblasted and painted, and then hoisted to the outside field for closing. After the bottom column is turned over, the second-layer column is turned over and buckled on the top surface of the bottom column, and then the top column deck is turned over and buckled on the top surface of the second-layer column. After welding, the column is formed; Crossbeam construction: Each crossbeam includes eight tube bodies, which include two horizontal braces, two upper vertical braces, two lower vertical braces and two diagonal braces. Each tube body is individually manufactured in the workshop through the process of cutting, rolling, welding and lengthening according to the tube section and length. After each tube body is individually manufactured, it is hoisted to the outside field for closing. The two diagonal braces are closed in an eight-shaped shape, the two horizontal braces are closed on both sides of the two diagonal braces, the two horizontal braces are respectively the upper horizontal brace and the lower horizontal brace, the two upper vertical braces are closed between the upper horizontal brace and the diagonal brace, and the two lower vertical braces are closed between the lower horizontal brace and the diagonal brace. The eight tube bodies are closed and welded to form a single piece; The second stage: loading and closing; After the three bottom sway control tanks are built, they are hoisted into the dock as a reference positioning. After the three columns are built, they are hoisted into the dock and closed with the corresponding bottom sway control tanks. Then the three completed monolithic bodies are hoisted into the dock and closed. When each monolithic body is closed, the two ends of the upper cross brace of the monolithic body are closed with the transition connection cone heads at the corresponding positions on the top vertical plate decks of the columns on both sides, and the two ends of the lower cross brace are closed with the transition connection cone heads at the corresponding positions on the bottom sway control tanks on both sides. After the three monolithic bodies are closed, a wind, light and fishery integrated floating wind turbine is formed.

[0007] Furthermore, after the disc segment is turned over to a normal position in the first stage, a column positioning plate is welded on the top surface of the upper top plate of the disc segment.

[0008] Furthermore, in the second stage, after the three monolithic bodies are closed, horizontal reinforcing beams are installed to connect the three monolithic bodies to each other. There are three groups of horizontal reinforcing beams, which are all closed on the inner sides of the three monolithic bodies and cooperate with the monolithic bodies to form a hexagonal structure. Each group of horizontal reinforcing beams consists of an upper reinforcing beam and a lower reinforcing beam.

[0009] Furthermore, during the construction of the beams in the first stage, each group of horizontal reinforcing beams is individually manufactured in the workshop through the processes of cutting, rolling, welding and lengthening. After the construction of the single-piece body is completed in the first stage, two positioning joints are respectively installed on the upper cross brace and the lower cross brace of each single-piece body. After the construction of the horizontal reinforcing beams is completed, they are hoisted into the dock, and the two ends of the upper reinforcing beams of each group of horizontal reinforcing beams are respectively closed with the positioning joints at the corresponding positions of the upper cross braces of the single-piece bodies on both sides, and the two ends of the lower reinforcing beams of each group of horizontal reinforcing beams are respectively closed with the positioning joints at the corresponding positions of the lower cross braces of the single-piece bodies on both sides.

[0010] The advantages of the present invention are: (1) The mounting technology of the present invention is to divide the bottom sway control tank into five sections for separate construction, then assemble them as a whole, and finally hoist them into the dock for reference positioning; the columns are divided into three sections for separate construction, then assemble them as a whole and hoist them into the dock for assembling with the bottom sway control tank; and the pipe bodies of the crossbeam are separately manufactured in the workshop, assembled and spliced ​​into a single piece outdoors, and then hoisted into the dock for assembling, thereby simplifying the manufacturing process and reducing the manufacturing difficulty and site requirements.

[0011] (2) The present invention improves the subsequent overall lifting and closing accuracy of the single-piece body by making transition connection cones on the columns and the bottom sway control cabin, thereby shortening the mounting cost and mounting cycle.

[0012] (3) The present invention welds a column positioning plate on the top surface of the upper top plate of the disc segment to provide positioning for the columns when the columns are subsequently closed, thereby reducing the difficulty of loading and improving the loading accuracy.

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Example like Figure 1 As shown, the wind, light and fishery integrated floating wind turbine includes three floating bodies distributed in a triangle, each floating body includes a bottom sway control cabin 1 and a column 2 located above the bottom sway control cabin 1, and the three floating bodies are connected by three beams 3 to form a whole. The three floating bodies are located at the three vertices of the triangle, and the three beams are the three sides of the triangle. In order to improve the overall structural strength of the floating wind turbine, horizontal reinforcement beams 4 are installed on the inner side of the three beams 3 to connect the three beams 3 to each other. The horizontal reinforcement beams 4 have three groups and cooperate with the beams 3 to form a hexagonal structure.

[0027] This embodiment provides a technology for mounting and closing a wind, solar and fishery integrated offshore floating wind turbine, which includes two stages: Phase 1: Construction in sections; Construction of the bottom sway control tank 1: The bottom sway control tank 1 is divided into five sections, and the five sections are constructed separately on the platform. The five sections include a disc section and four arc sections; like Figure 2As shown, when the disc segment is built separately, the upper top plate is used as the base surface for reverse construction, and the internal components and the ring plate are installed in sequence. The lower bottom plate is turned over and covered and then formed as a whole. The disc segment is turned over and in a normal state. The column positioning plate 8 is welded on the top surface of the upper top plate of the disc segment to provide positioning for the subsequent second stage of column closure, which reduces the difficulty of loading and improves the loading accuracy. like Figure 3 As shown, each arc segment is constructed with the lower bottom plate as the base surface, and after the internal components and the ring plate are installed on the lower bottom plate, the upper bottom plate is finally buckled. After the four arc segments are constructed separately, a first transition connection cone head 5 is installed on two adjacent arc segments respectively. like Figure 4 As shown, after all five sections are built separately, they are hoisted to the outside field for closure. The four arc sections are spliced ​​together into a circular ring and arranged around the disc section. After the assembly is completed, a bottom sway control cabin is formed.

[0028] Column construction: The columns are divided into three sections, which are built separately on the platform. The three sections are the bottom column, the second column and the top column deck; like Figure 5 As shown, when each segment is constructed, the watertight platform is used as the base surface of the frame to reversely build the surrounding wall plate and the internal bulkhead plate. When the top column deck is constructed, two second transition connection cone heads 7 need to be installed on the surrounding wall plate of the top vertical plate deck; like Figure 6 As shown, after all three sections are built separately, they are sandblasted and painted, and then hoisted to the outside site for closure. After the bottom column is turned over, the second-layer column is turned over and buckled on the top surface of the bottom column, and then the top column deck is turned over and buckled on the top surface of the second-layer column. After welding is completed, the column is formed.

[0029] Beam construction: Each beam consists of eight tubes, which include two horizontal braces, two upper vertical braces, two lower vertical braces and two diagonal braces; like Figure 7 As shown, each pipe body is individually manufactured in the workshop through the process of cutting, rolling, welding and lengthening according to the pipe section and length. like Figure 8 As shown, after each pipe body is manufactured separately, it is hoisted to the outside field for closing, the two diagonal braces are closed in an eight-shaped shape, the two horizontal braces are closed on both sides of the two diagonal braces, the two horizontal braces are respectively closed on both sides of the two diagonal braces, the two upper vertical braces are closed between the upper horizontal brace and the diagonal brace, the two lower vertical braces are closed between the lower horizontal brace and the diagonal brace, the eight pipe bodies are closed and welded to form a single body, and two positioning joints 6 are respectively installed on the upper horizontal brace and the lower horizontal brace of each single body.

[0030] Construction of horizontal reinforcing beams: Each set of horizontal reinforcing beams consists of an upper reinforcing beam and a lower reinforcing beam. Each set of horizontal reinforcing beams is individually manufactured in the workshop through the process of cutting, rolling, welding and connecting.

[0031] In this stage, the bottom sway control cabin 1, the column 2, the beam 3 and the horizontal reinforcement beam 4 are constructed simultaneously, which effectively shortens the construction period, and adopts a segmented construction method, which reduces the requirements for the construction site.

[0032] The second stage: loading and closing; like Fig. 9 As shown, after the three bottom swing control cabins are built, they are hoisted into the dock as a reference positioning. After the three columns are built, they are hoisted into the dock and closed with the corresponding bottom swing control cabins. Then the three completed monolithic bodies are hoisted into the dock for closing. When each monolithic body is closed, the two ends of the upper cross brace of the monolithic body are respectively closed with the transition connection cone heads at the corresponding positions on the top vertical plate decks of the columns on both sides, and the two ends of the lower cross brace are respectively closed with the transition connection cone heads at the corresponding positions on the bottom swing control cabins on both sides. After the three monolithic bodies are closed, the horizontal reinforcing beams are hoisted into the dock, and the two ends of the upper reinforcing beams of each group of horizontal reinforcing beams are respectively closed with the positioning joints at the corresponding positions of the upper cross braces of the monolithic bodies on both sides, and the two ends of the lower reinforcing beams of each group of horizontal reinforcing beams are respectively closed with the positioning joints at the corresponding positions of the lower cross braces of the monolithic bodies on both sides. After all welding is completed, a wind-light-fishing integrated floating wind turbine is formed.

[0033] The loading technology of the present invention is to divide the bottom sway control cabin into five sections for separate construction, then fold them together, and finally hoist them into the dock for reference positioning. The columns are divided into three sections for separate construction, then hoisted into the dock after folding together with the bottom sway control cabin, and the pipe bodies of the crossbeam are separately manufactured in the workshop, then folded and spliced ​​into a single piece in the field, and then hoisted into the dock for folding, which simplifies the manufacturing process, reduces the manufacturing difficulty and the requirements for the site. In addition, by installing transition connection cones on the columns and the bottom sway control cabin in advance, and installing positioning joints on the single piece in advance before loading and folding, the folding difficulty is reduced, and the loading and folding accuracy and speed are improved.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
