For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0047] As Figures 1-10 shown, in a first aspect, the embodiments of the present application propose a floating offshore converter station transportation device, which comprises a shipping part 1; a floating part 2 for carrying a converter station 8, the floating part 2 is used to make the converter station 8 float on the water surface, the floating part 2 is placed on the upper surface of the shipping part 1, the tugboat drives the floating part 2 to move to the predetermined sea area through the shipping part 1, the floating part 2 has a cavity structure inside, so that when the floating part 2 is separated from the shipping part 1, the converter station 8 can float on the sea surface without sinking; a lifting assembly 3 installed on the upper surface of the floating part 2, the lifting assembly 3 is used to adjust the vertical height of the converter station 8 when installing the converter station 8 to make the converter station 8 reach the predetermined height position; a buffer 4 clamped between the floating part 2 and the shipping part 1.

[0048] In the specific implementation of the embodiment, the converter station 8 is hoisted by the roadbed hoisting equipment onto the floating part 2 placed on the end surface of the carrying part 1, the posture of the carrying part 1 in water is adjusted by the buoyancy adjusting member, so that the carrying part 1 floats on the sea surface, and then the carrying part 1 is carried to the predetermined sea area by the tugboat; after reaching the predetermined sea area, the posture of the carrying part 1 in water is adjusted by the buoyancy adjusting member, so that the carrying part 1 gradually sinks into the water, and in the sinking process, the sinking speed and the buoyancy of the carrying part 1 are controlled by the buoyancy adjusting member, so that the floating part 2 can be stably maintained in the floating state; when the carrying part 1 is completely sunk into the water, the converter station 8 is moved upward by the lifting assembly 3, so that the converter station 8 is moved to the predetermined height, and when the predetermined height is reached, the converter station 8 is positioned and locked, so that the converter station 8 is in the current predetermined position; then the floating part 2 is fixedly connected with the foundation preset in the seabed in advance by the anchor chain 6, and thus the installation and construction of the converter station 8 are realized; the above entire process is performed without hoisting equipment, effectively solving the dependence on large hoisting ships in the installation and construction process of the converter station 8 in the deep sea, the construction method is simple and fast, and the offshore installation and construction efficiency of the converter station 8 is improved. After the installation of the converter station 8 is completed, the carrying part 1 and the floating part 2 are separated by the tugboat, and the posture of the carrying part 1 (empty load) in water is adjusted by the buoyancy adjusting member, so that the carrying part 1 is re-floated on the sea surface, and the carrying part 1 is towed back to the roadbed or the shore by the tugboat, so that recycling is realized, and the expenditure of the engineering cost is reduced.

[0049] In some embodiments of the present application, the buffer member 4 in the present scheme is an air bag body 41 (which is internally filled with a certain amount of gas), which is used to buffer the vibration and relative displacement between the floating part 2 and the carrying part 1 caused by unstable factors such as sea waves or water flow during the carrying process, so as to ensure the relative stability between the floating part 2 and the carrying part 1 during the carrying process.

[0050] In some embodiments of the present application, as shown in FIG. 6, the air bag body 41 is provided with a plurality of air holes 411, and the air holes 411 are connected with the air inlet pipe 42 and the air outlet pipe 43. Figure 3As shown, the buffer 4 further comprises an elastic rubber member 42 (fixedly mounted on the carrying part 1), which is arranged outside the air bag body 41, surrounds the outer periphery of the air bag body 41, and is connected with the outer periphery of the air bag body 41 (the air bag body 41 and the elastic rubber member 42 can be fixedly connected by means of gluing); a plurality of spherical cavities 26 are arranged on the elastic rubber member 42 and spaced apart around the axial center line of the air bag body 41, a guide ball 43 is arranged in each spherical cavity 26, the guide ball 43 can freely rotate in the spherical cavity 26, the guide ball 43 at least partially extends upward out of the spherical cavity 26 and protrudes from the upper end surface of the elastic rubber member 42; specifically, a spherical bushing can be arranged in each spherical cavity 26, a plurality of rollable balls are arranged on the wall of the spherical bushing (the balls and the spherical bushing are not shown in the figure because they are prior art), the outer periphery of the guide ball 43 is in sliding cooperation with the balls, so as to realize the effect that the guide ball 43 freely rotates in the spherical cavity 26; in this embodiment, the air bag body 41 is circular, and the elastic rubber member 42 is annular (the shapes of the air bag body 41 and the elastic rubber member 42 are not limited to the above shapes, and can be any other shape).

[0051] After the construction personnel carry the converter station 8 to the predetermined sea area and complete the fixed installation of the converter station 8, the carrying part 1 and the floating part 2 need to be separated at this time, at this time, the towing force is applied to the carrying part 1 by the tugboat, so that the carrying part 1 moves relative to the floating part 2 in the horizontal direction, as shown in Figure 10 As shown, while the carrying part 1 moves relative to the floating part 2 in the horizontal direction, the bottom wall of the floating part 2 and the part of the guide ball 43 protruding out of the spherical cavity 26 are in contact, and the guide ball 43 is caused to rotate in the spherical cavity 26, so that the sliding friction between the floating part 2 and the elastic rubber member 42 is changed into rolling friction, the friction between them is reduced, which helps the carrying part 1 and the floating part 2 to be better separated; since the guide ball 43 can freely rotate in the spherical cavity 26, no matter the moving direction of the carrying part 1 relative to the floating part 2, the guide ball 43 can be driven to rotate, thereby assisting the carrying part 1 and the floating part 2 to be quickly separated, improving the work efficiency.

[0052] In some embodiments of the present application, as Figure 3As shown, this embodiment provides a method for fixing the elastic rubber component 42 and the transport section 1. Multiple first grooves 12 are provided on the upper surface of the transport section 1 located outside the elastic rubber component 42. A first rod 13 is installed in each of the first grooves 12. Multiple second grooves 22 are provided on the elastic rubber component 42. A second rod 23 is installed in each of the second grooves 22. The first grooves 12 and second grooves 22 are spaced apart around the axial center line of the airbag body 41, and the first grooves 12 and second grooves 22 are arranged in a one-to-one correspondence. A first pull rope 21 connects the first rod 13 and the second rod 23 (the two ends of the first pull rope 21 are respectively tied to the first rod 13 and the second rod 23), thereby fixing the elastic rubber component 42 to the transport section 1 via the multiple first pull ropes 21 (e.g., ...). Figure 1 (As shown).

[0053] To ensure the relative stability between the floating part 2 and the transport part 1 during the transfer process, and to prevent the floating part 2 from shifting significantly relative to the buffer 4 due to ocean waves in the deep sea (which would weaken the buffering effect on vibrations between the floating part 2 and the transport part 1), this embodiment also incorporates certain fixing measures between the floating part 2 and the buffer 4, such as... Figure 5 As shown, a third groove 24 is provided on the outer peripheral wall of the floating part 2, and a third rod 25 (arc-shaped) is installed in the third groove 24. By setting a second pull rope 11, with one end of the second pull rope 11 tied to the third rod 25 and the other end tied to the second rod 23, the relative position between the floating part 2 and the buffer 4 is stabilized, so that the floating part 2 is as completely positioned on the buffer 4 as possible, without deviating from the buffer 4. When the installation of the converter station 8 is completed and it is necessary to separate the transport part 1 and the floating part 2, the construction personnel need to first untie the second pull rope 11, and then operate the tugboat to detach the transport part 1 from the floating part 2.

[0054] In some embodiments of this application, the buoyancy adjustment component is a ballast tank located within the transport section 1. The ballast tank is connected to a water pump (both are prior art, and their working principles will not be described in detail here). Construction personnel control the operation of the water pump to replenish a predetermined amount of water into the ballast tank, thereby controlling the sinking of the transport section 1 in the water. By controlling the amount of water replenished by the water pump, the sinking speed of the transport section 1 is controlled, allowing the floating section 2 to maintain a stable floating state. In this solution, two water pumps are provided, one for replenishing water and one for draining water. After the transport section 1 and the floating section 2 are separated, the water in the ballast tank can be drained out by the drain pump, allowing the transport section 1 to return to a floating state. Then, a tugboat can be used to tow it back to the shore for recycling and reuse.

[0055] In some embodiments of this application, such as Figure 1As shown, the lifting assembly 3 comprises self-lifting legs 31 fixedly installed on the upper surface of the floating part 2, the self-lifting legs 31 are provided in a plurality of numbers and are arranged at intervals around the axial center line of the floating part 2; a load bearing 32 for bearing the converter station 8 is arranged between the plurality of self-lifting legs 31, the load bearing 32 is fixedly connected with the plurality of self-lifting legs 31; the self-lifting legs 31 are used to adjust the vertical height of the converter station 8.

[0056] During the transportation of the converter station 8 to the predetermined sea area, the self-lifting legs 31 are all in the retracted state, and the converter station 8 is in the lowest position, so as to make the center of gravity of the overall device as low as possible (to ensure the stability during the transportation); after the converter station 8 is transported to the predetermined sea area, the converter station 8 is moved upward by the plurality of self-lifting legs 31 arranged on the upper end surface of the floating part 2, and the converter station 8 is raised to the predetermined height.

[0057] In some embodiments of the present application, as shown in Figure 6 The self-lifting leg 31 comprises a guide rod 311 fixedly installed on the upper surface of the floating part 2 and a lifting cylinder 312, the lifting cylinder 312 has a containing cavity 3121 therein, the guide rod 311 is contained in the containing cavity 3121, and the lifting cylinder 312 is slidingly connected to the guide rod 311 (as shown in Figure 8 、 Figure 9 As shown, a slide groove 3122 extending upward and downward is arranged on the side wall of the containing cavity 3121, a slide rod 3111 slidingly assembled in the slide groove 3122 is arranged at the corresponding position of the side wall of the guide rod 311, so that the lifting cylinder 312 can slide along the vertical predetermined track relative to the guide rod 311, and the containing cavity 3121 is provided with one side wall of the slide groove 3122 and the guide rod 311 is provided with one side wall of the slide rod 3111 abutting); the outer walls of the plurality of lifting cylinders 312 are fixedly connected with the load bearing 32 (the load bearing 32 is a steel plate for lifting the converter station 8); as shown in Figure 6 、 Figure 7 As shown, a climbing rack 313 extending upward and downward is arranged on the side wall of the guide rod 311, a gear wheel 314 meshing with the climbing rack 313 is rotatably installed in the containing cavity 3121, and the gear wheel 314 is connected with a lifting motor (a housing for containing the lifting motor is arranged on the outer wall of the lifting cylinder 312), as shown in Figure 6As shown, the climbing racks 313 are provided with two, the gears 314 are also provided with two, and the two climbing racks 313 are respectively arranged on the two mutually symmetrical side walls of the guide rod 311; the locking racks 315 (the locking racks 315 are provided with two, and are respectively arranged in correspondence with the two climbing racks 313) for locking and positioning the guide rod 311 are arranged in the accommodating cavity 3121. Specifically, the locking racks 315 are connected with the telescopic rods 316 (which are electric rods) arranged in the accommodating cavity 3121. The telescopic rods 316 can drive the locking racks 315 to move towards the corresponding climbing racks 313, so that the locking racks 315 are engaged with the climbing racks 313, thereby realizing the locking between the lifting cylinder 312 and the guide rod 311.

[0058] In the specific implementation of the embodiment, the lifting motor drives the gears 314 to rotate, and then the gears 314 and the climbing racks 313 are matched to drive the lifting cylinder 312 to climb upwards relative to the guide rod 311. The plurality of lifting cylinders 312 are synchronously moved upwards, and the converter station 8 is moved upwards by the carrier 32. When the lifting motor stops working (the lifting motor should be selected to be a motor with self-locking function when losing power), the locking racks 315 are moved towards the climbing racks 313 by the telescopic rods 316, so that the locking racks 315 are engaged with the climbing racks 313, thereby realizing the locking of the lifting cylinder 312.

When the converter station 8 approaches the predetermined height position, the positions of the locking racks 315 and the climbing racks 313 are observed in real time by the camera, so that when the teeth on the locking racks 315 and the teeth on the climbing racks 313 are in the corresponding state, the lifting motor is controlled to stop working. At this time, the locking racks 315 are moved towards the climbing racks 313 by the telescopic rods 316, so that the teeth on the locking racks 315 can be clamped with the teeth on the climbing racks 313, thereby realizing the locking effect.
