[0044] This embodiment provides a method for assembling an offshore floating body. Figures 1 to 10 As shown, the method for assembling an offshore floating body comprises the following steps:

[0045] S100, setting up an installation platform 1 on the coast, and positioning the floating pipe 01 on the installation platform 1;

[0046] S200, placing pontoons 02 on both sides of the floating tube 01 that are axially opposite to each other, and positioning the pontoons 02 by installing the platform 1;

[0047] S300, fixing the floating tube 01 and the pontoon 02, and fixing the photovoltaic panel 03 on the floating tube 01, and finally assembling a complete offshore floating body;

[0048] S400, transferring the assembled offshore floating body to the transport vehicle 2, and transporting the offshore floating body to the estuary by the transport vehicle 2;

[0049] S500, the offshore floating body on the transport vehicle 2 is transferred to the sea surface through the sea estuary, and transported to the target location at sea.

[0050] In this embodiment, first, an installation platform 1 is set up on the coast, and the floating tube 01 is positioned on the installation platform 1. Subsequently, pontoons 02 are placed on both sides of the floating tube 01 that are axially opposite to each other, and the pontoons 02 are positioned by the installation platform 1 to fix the pontoons 02 in the installation position relative to the floating tube 01. Next, the floating tube 01 and the pontoons 02 are fixed, and the photovoltaic panel 03 is fixed on the floating tube 01, so that the floating tube 01, the pontoons 02 and the photovoltaic panel 03 are connected as a whole, and finally assembled into a complete offshore floating body. After the offshore floating body is assembled, the offshore floating body is transferred to the operating vehicle 2, and the offshore floating body is transported to the estuary on the coast by the operating vehicle 2, that is, the offshore floating body from below the estuary. The offshore floating body on the operating vehicle 2 is transported to the sea surface through the estuary, and finally transported to the target position at sea. The above method enables offshore floating bodies to be assembled near the shore and quickly transported to the sea surface after assembly. This can avoid the problem of long-distance land transportation of offshore floating bodies, reduce the consumption of manpower and material resources, and ensure the safety and reliability of short-distance transportation.

[0051] In this embodiment, the installation platform 1 is provided with a first positioning portion 11 and a second positioning portion 12; in step S100, the first positioning portion 11 limits the radial direction of the floating tube 01, and the second positioning portion 12 limits the axial direction of the floating tube 01. The cooperation of the first positioning portion 11 and the second positioning portion 12 can limit the axial direction and radial direction of the floating tube 01, thereby ensuring reliable fixation of the floating tube 01.

[0052] Specifically, the first positioning portion 11 includes a first positioning member 111, and the first positioning member 111 includes a positioning seat 1111, a first limiting plate 1112, and a second limiting plate 1113. The first limiting plate 1112 and the second limiting plate 1113 are respectively arranged at two ends of the positioning seat 1111, and the first limiting plate 1112 and the second limiting plate 1113 are both in contact with the outer wall of the floating tube 01. Specifically, the floating tube 01 is supported on the first limiting plate 1112 and the second limiting plate 1113 at the same time, so that the floating tube 01 can be provided with reliable radial limiting.

[0053] Furthermore, the first positioning member 111 also includes a reinforcing plate, the reinforcing plate 1114 is located between the first limiting plate 1112 and the second limiting plate 1113, the first end of the reinforcing plate 1114 is fixedly connected to the first limiting plate 1112, and the second end of the reinforcing plate 1114 is fixedly connected to the second limiting plate 1113. The provision of the reinforcing plate 1114 can enhance the overall strength of the first positioning member 111.

[0054] In this embodiment, in the radial direction of the floating tube 01, the position of the first positioning part 11 relative to the mounting platform 1 is set to be adjustable. Specifically, the first positioning part 11 also includes a positioning assembly 112. The positioning assembly 112 includes a first positioning block 1121 and a second positioning block 1122, and the first positioning block 1121 and the second positioning block 1122 are arranged at intervals along the axial direction of the floating tube 01, and a positioning groove can be formed between the first positioning block 1121 and the second positioning block 1122. Specifically, the positioning seat 1111 of the first positioning member 111 is placed in the positioning groove, and the positioning seat 1111 can be displaced in the positioning groove along the radial direction of the floating tube 01, so as to adjust the position.

[0055] In this embodiment, the second positioning part 12 includes a second positioning member 121 and a third positioning member 122. The end of the floating tube 01 is arranged on the second positioning member 121, and the third positioning member 122 is arranged on the second positioning member 121. The third positioning member 122 is used to abut against the end surface of the floating tube 01 to limit the axial direction of the floating tube 01. Specifically, the second positioning member 121 includes a positioning base plate 1211 and a positioning connection block 1212 arranged on the positioning base plate 1211. The positioning base plate 1211 has a first limiting groove 1213, and the positioning connection block 1212 has a second limiting groove 1214. The first limiting groove 1213 is connected to the first limiting groove 1213. The two sides of the third positioning member 122 are respectively inserted into the first limiting groove 1213 and the second limiting groove 1214, so that the third positioning member 122 is fixed.

[0056] In this embodiment, the positioning base plate 1211 and the positioning connection block 1212 are vertically arranged.

[0057] Specifically, the third positioning member 122 includes an abutment plate 1221 and a connection plate 1222 that are connected to each other. The two sides of the connection plate 1222 are respectively inserted into the first limiting groove 1213 and the second limiting groove 1214, so that the connection plate 1222 is reliably fixed on the second positioning member 121. When the floating tube 01 is placed on the second positioning member 121, the end of the floating tube 01 is supported on the positioning bottom plate 1211, and the end of the floating tube 01 is abutted against the abutment plate 1221, so as to achieve axial positioning of the floating tube 01.

[0058] Specifically, after the axial positioning of the floating tube 01 is completed by using the third positioning member 122 , the third positioning member 122 is removed, and the buoyancy box 02 is installed between the positioning base plate 1211 and the positioning connection block 1212 , so as to be positioned and installed with the end of the floating tube 01 .

[0059] In this embodiment, the installation platform 1 is provided with a third positioning portion 13. In step S200, the buoyancy box 02 is limited in the radial direction of the floating tube 01 by the third positioning portion 13. Specifically, the third positioning portion 13 is configured as a triangular positioning plate, one side of which can abut against one end of the buoyancy box 02 to limit the buoyancy box 02 in the radial direction of the floating tube 01. In this way, the stability of the third positioning portion 13 can be ensured.

[0060] Specifically, the end of the floating tube 01 is fixedly connected to the buoyancy box 02 at the corresponding end by connecting members such as bolts.

[0061] Optionally, a cushion block 14 is further provided on the installation platform 1, and the cushion block 14 is installed below the floating tube 01. The cushion block 14 is located at the center of the floating tube 01. Since the floating tube 01 is long and heavy, the cushion block 14 is installed below the floating tube 01 to fill the gap between the middle of the floating tube 01 and the installation platform 1, which can prevent the floating tube 01 from being deformed after being placed for a long time.

[0062] In this embodiment, in step S300, a first gantry crane 3 is set at the coast, and the photovoltaic panel 03 is hoisted by the first gantry crane 3, and the photovoltaic panel 03 is transported to the installation position relative to the floating tube 01. Specifically, a first slide rail 31 extending along a first direction is provided on the installation platform 1, and the first gantry crane 3 can slide relative to the installation platform 1 along the first direction. A first hook is provided on the first gantry crane 3, and the first hook can adjust the position along the second direction. Exemplarily, in this embodiment, there are two first slide rails 31, and the two first slide rails 31 are arranged at intervals along the second direction. A plurality of installation platforms 1 are arranged between the two first slide rails 31. Such an arrangement can further enhance the installation efficiency of the offshore floating body on the coast.

[0063] Specifically, the photovoltaic panel 03 is connected to the connecting frame 04, and the floating tube 01 is correspondingly provided with a fixing block 011. After the photovoltaic panel 03 is hoisted by the first gantry crane 3, the first hook is moved to move the photovoltaic panel 03 to the top of the floating tube 01 to be installed. Then, with the assistance of the on-site operator, the connecting frame 04 is docked to the target position of the fixing block 011, and then fixedly connected by bolts and other connectors. The offshore floating body after final assembly presents Fig.10 The structure shown in .

[0064] In this embodiment, in step S400, the assembled offshore floating body is hoisted by the first gantry crane 3, and the offshore floating body is transported to the transport vehicle 2, so that the floating tube 01 is placed in the receiving groove 211 provided on the transport vehicle 2. Specifically, when the offshore floating body needs to be transported, the transport vehicle 2 is moved to the lifting area of ​​the first gantry crane 3, the first gantry crane 3 hoists and moves the offshore floating body, and finally places the offshore floating body on the transport vehicle 2. Specifically, a support block 21 is provided on the transport vehicle 2, and the support block 21 is provided with a receiving groove 211. The receiving groove 211 fits with the outer peripheral wall of the floating tube 01 of the offshore floating body, the first gantry crane 3 hoists the offshore floating body, and finally places the floating tube 01 in the corresponding receiving groove 211, thereby realizing the reliable accommodation of the offshore floating body and preventing the offshore floating body from moving randomly relative to the transport vehicle 2.

[0065] Optionally, the transfer vehicle can be configured as an automated guided vehicle (AGV) to achieve reliable transportation of offshore floating bodies during short-distance transportation.

[0066] In this embodiment, in step S500, a second gantry crane 4 is provided on one side of the estuary, and the offshore floating body on the transport vehicle 2 is hoisted by the second gantry crane 4, and the offshore floating body is transferred to the sea surface through the estuary. Specifically, a second slide rail 32 extending along the second direction is provided on the installation platform 1, and the second gantry crane 4 can slide relative to the installation platform 1 along the second direction. A second hook is provided on the second gantry crane 4, and the second hook can adjust the position along the first direction. Exemplarily, in this embodiment, there are two second slide rails 32, and the two second slide rails 32 are arranged at intervals along the second direction. Specifically, the estuary is located between the two second slide rails 32, and the position below the second hook corresponds to the position of the estuary. Specifically, the transport vehicle 2 carries the offshore floating body and moves it to the lifting area of ​​the second gantry crane 4, the second gantry crane 4 hoists and moves the offshore floating body, and finally drops the offshore floating body from the transport vehicle 2 through the estuary and transfers it to the sea surface.

[0067] In this embodiment, the arrangement of the first gantry crane 3 and the second gantry crane 4 can meet the requirements of offshore lifting of offshore floating bodies without the need for additional construction machinery such as cranes, thereby reducing the cost of manpower and material resources to a certain extent.

[0068] In this embodiment, in step S500, the offshore floating body is transported to the offshore target location by the shipping ship. Specifically, the shipping ship is on standby at the estuary. When the second gantry crane 4 drops the offshore floating body from the transport vehicle 2 through the estuary and transfers it to the sea surface, the shipping ship connects the offshore floating body through a structure such as a chain, and finally tows the offshore floating body to the offshore target location.

[0069] In summary, the assembly method of the offshore floating body provided in this embodiment enables the offshore floating body to be assembled near the shore, and can be quickly transported to the sea surface after the assembly is completed, which can avoid the problem of long-distance land transportation of the offshore floating body, reduce the consumption of manpower and material resources, and ensure the safety and reliability of short-distance transportation.
