It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0047] like Figure 1-Figure 10 As shown, in the first aspect, the embodiment of the present application proposes a floating offshore converter station transportation equipment, including a consignment part 1; used to be connected to a tugboat, the consignment part 1 has a buoyancy adjustment part, and the buoyancy adjustment part is used to control the floating and sinking of the consignment part 1 in the water; a floating part 2, used to carry 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 consignment part 1, and the tugboat drives the floating part 2 to move to a predetermined sea area through the consignment part 1, and the floating part 2 has a cavity structure inside, so that when the floating part 2 is separated from the consignment part 1, the converter station 8 can float on the sea surface without sinking; a lifting component 3, installed on the upper surface of the floating part 2, the lifting component 3 is used to adjust the vertical height of the converter station 8 when installing the converter station 8 after reaching the predetermined sea area, so that the converter station 8 reaches a predetermined height position; a buffer 4, clamped between the floating part 2 and the consignment part 1.

[0048] During the specific implementation of this embodiment, the converter station 8 is hoisted onto the floating part 2 placed on the upper end surface of the consignment part 1 by using the roadbed lifting equipment, and the posture of the consignment part 1 in the water is adjusted by the buoyancy adjusting part so that the consignment part 1 floats on the sea surface, and then the consignment part 1 is consigned to the predetermined sea area by a tugboat; after arriving at the predetermined sea area, the posture of the consignment part 1 in the water is adjusted by the buoyancy adjusting part so that the consignment part 1 gradually sinks into the water. During the sinking process, the sinking speed of the consignment part 1 and the size of the buoyancy it receives are controlled by the buoyancy adjusting part so that the floating part 2 can stably maintain a floating state; when the consignment part 1 moves downward, the buoyancy adjusting part controls the sinking speed of the consignment part 1 and the size of the buoyancy it receives, ... maintain a floating state, and when the consignment part 1 moves downward, After being completely sunk into the water, the converter station 8 is driven to move upward by the lifting assembly 3, so that the converter station 8 moves up 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 to the foundation preset on the seabed by the anchor chain 6, so as to realize the installation and construction of the converter station 8; the above-mentioned whole process is carried out without the need for lifting equipment, which effectively solves the dependence on large lifting vessels during the installation and construction of the deep-sea converter station 8. 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 consignment part 1 is separated from the floating part 2 by a tugboat, and the posture of the consignment part 1 (empty) in the water is adjusted by the buoyancy adjustment part, so that the consignment part 1 floats on the sea again, and the consignment part 1 is towed back to the roadbed or the shore by a tugboat to achieve recycling and reuse, thereby reducing the expenditure of engineering costs.

[0049] In some embodiments of the present application, the buffer member 4 in this solution is an airbag 41 (filled with a certain amount of gas), and the airbag 41 is used to buffer the vibration and relative displacement between the floating part 2 and the consignment part 1 caused by unstable factors such as waves or water currents during the consignment process, thereby ensuring the relative stability between the floating part 2 and the consignment part 1 during the consignment process.

[0050] In some embodiments of the present application, Figure 3As shown, the buffer member 4 also includes an elastic rubber member 42 (fixedly installed on the consignment part 1), the elastic rubber member 42 is arranged on the outside of the airbag body 41, the elastic rubber member 42 is arranged around the outer periphery of the airbag body 41, and the elastic rubber member 42 is fitted and connected to the outer periphery of the airbag body 41 (the airbag body 41 and the elastic rubber member 42 can be fixedly connected by gluing); a plurality of spherical cavities 26 are arranged on the elastic rubber member 42 around the axial center line of the airbag body 41, and a guide ball 43 is arranged in the spherical cavity 26, and the guide ball 43 can rotate freely in the spherical cavity 26, and the guide ball 43 is at least partially upward It extends 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 provided in the spherical cavity 26, and a plurality of rollable balls are provided on the wall of the spherical bushing (since it is a prior art, the balls and the spherical bushing are no longer shown in the figure), and the outer periphery of the guide ball 43 and the balls slide in cooperation to achieve the effect of free rotation of the guide ball 43 in the spherical cavity 26; in this embodiment, a circular airbag body 41 and an annular elastic rubber member 42 are provided (the shapes of the airbag body 41 and the elastic rubber member 42 are not limited to the above shapes, and can also be any other shapes).

[0051] After the construction personnel have shipped the converter station 8 to the predetermined sea area and completed the fixed installation of the converter station 8, it is necessary to separate the shipping part 1 from the floating part 2. At this time, a tugboat is used to apply a dragging force to the shipping part 1, so that the shipping part 1 moves relative to the floating part 2 in the horizontal direction. Fig.10 As shown, while the consignment part 1 moves horizontally relative to the floating part 2, the bottom wall of the floating part 2 and the guide ball 43 protruding from the spherical cavity 26 are brought into contact, and the guide ball 43 is prompted to rotate in the spherical cavity 26, so that the sliding friction between the floating part 2 and the elastic rubber part 42 is converted into rolling friction, thereby reducing the friction between the two, which helps to better separate the consignment part 1 and the floating part 2; since the guide ball 43 can rotate freely in the spherical cavity 26, no matter what the moving direction of the consignment part 1 is relative to the floating part 2, it can drive the guide ball 43 to rotate, thereby assisting the consignment part 1 and the floating part 2 to quickly separate, thereby improving working efficiency.

[0052] In some embodiments of the present application, Figure 3As shown, this embodiment provides a method for fixing and installing an elastic rubber member 42 and a consignment portion 1, wherein a plurality of first grooves 12 are provided on the upper surface of the consignment portion 1 located outside the elastic rubber member 42, a first rod 13 is installed in the first groove 12, a plurality of second grooves 22 are provided on the elastic rubber member 42, a second rod 23 is installed in the second groove 22; the first grooves 12 and the second grooves 22 are arranged at intervals around the axial center line of the airbag body 41, and the first grooves 12 and the second grooves 22 are arranged one by one; a first pull rope 21 is connected between the first rod 13 and the second rod 23 (the two ends of the first pull rope 21 are respectively tied together with the first rod 13 and the second rod 23), and then the elastic rubber member 42 is fixedly installed on the consignment portion 1 (such as Figure 1 shown).

[0053] In order to ensure the relative stability between the floating part 2 and the shipping part 1 during the transfer process, so as to prevent the waves in the deep sea from causing the floating part 2 to have a large displacement relative to the buffer 4, causing the floating part 2 to deviate from the buffer 4 (weakening the buffering effect of the vibration between the floating part 2 and the shipping part 1), this embodiment also provides 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 (in an arc shape) is installed in the third groove 24. By providing a second pull rope 11, and tying one end of the second pull rope 11 to the third rod 25 and the other end to the second rod 23, the relative position between the floating part 2 and the buffer 4 is stabilized, and the floating part 2 is completely located on the buffer 4 as much as possible without deviating from the buffer 4. When the installation of the converter station 8 is completed and the consignment part 1 and the floating part 2 need to be separated, the construction personnel need to first untie the second pull rope 11, and then operate the tugboat to separate the consignment part 1 from the floating part 2.

[0054] In some embodiments of the present application, the buoyancy adjustment member is a ballast tank provided in the consignment part 1, and the ballast tank is connected to a water pump (all of which are prior art, and the present application will not explain its working principle in detail). The 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 consignment part 1 in the water; by controlling the water replenishment amount of the water pump, the sinking speed of the consignment part 1 is controlled, so that the floating part 2 can be stably maintained in a floating state. In this solution, two water pumps are provided, one for replenishing water and the other for draining water. When the consignment part 1 and the floating part 2 are separated, the water in the ballast tank can be discharged outward through the drainage pump, so that the consignment part 1 is restored to a floating state again, and then it is towed back to the shore by a tugboat for recycling and reuse.

[0055] In some embodiments of the present application, Figure 1As shown, the lifting assembly 3 includes a self-lifting leg 31 fixedly mounted on the upper surface of the floating portion 2, and the self-lifting leg 31 has a plurality of self-lifting legs 31, and the plurality of self-lifting legs 31 are arranged at intervals around the axial center line of the floating portion 2; a bearing member 32 for bearing the converter station 8 is provided between the plurality of self-lifting legs 31, and the bearing member 32 is fixedly connected to 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 process of transporting the converter station 8 to the predetermined sea area, the self-lifting legs 31 are all in a retracted state, and the converter station 8 is in the lowest position, so that the center of gravity of the entire equipment is kept as low as possible (to ensure stability during the transport process); after the converter station 8 is transported to the predetermined sea area, the converter station 8 is driven upward by a 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 a predetermined height.

[0057] In some embodiments of the present application, Figure 6 As shown, the self-lifting leg 31 includes a guide rod 311 fixedly mounted on the upper surface of the floating part 2 and a lifting cylinder 312. The lifting cylinder 312 has a receiving cavity 3121, the guide rod 311 is received in the receiving cavity 3121, and the lifting cylinder 312 is slidably connected to the guide rod 311 (as shown in FIG. Figure 8 , Fig. 9 As shown, a slide groove 3122 extending up and down is provided on the side wall of the accommodating cavity 3121, and a slide rod 3111 slidably assembled in the slide groove 3122 is provided at a corresponding position on the side wall of the guide rod 311, so that the lifting cylinder 312 can slide along a vertical predetermined track relative to the guide rod 311, and a side wall of the accommodating cavity 3121 provided with the slide groove 3122 and a side wall of the guide rod 311 provided with the slide rod 3111 are in contact with each other); the outer walls of the plurality of lifting cylinders 312 are fixedly connected to the bearing member 32 (the bearing member 32 is a steel plate used to lift the converter station 8); as shown Figure 6 , Figure 7 As shown, a climbing rack 313 extending up and down is provided on the side wall of the guide rod 311, a gear 314 meshing with the climbing rack 313 is rotatably installed in the accommodating cavity 3121, and the gear 314 is connected to a lifting motor (a housing for accommodating the lifting motor is provided on the outer wall of the lifting cylinder 312), as shown in FIG. Figure 6As shown, two climbing racks 313 are provided, and two gears 314 are also provided. The two climbing racks 313 are respectively provided on two symmetrical side walls of the guide rod 311; a locking rack 315 for locking and positioning the guide rod 311 is provided in the accommodating cavity 3121 (two locking racks 315 are provided, respectively corresponding to the two climbing racks 313). Specifically, the locking rack 315 is connected to a telescopic rod 316 (an electric rod) provided in the accommodating cavity 3121. The telescopic rod 316 can drive the locking rack 315 to move toward the corresponding climbing rack 313, so that the locking rack 315 is meshed with the climbing rack 313, thereby realizing the locking between the lifting cylinder 312 and the guide rod 311.

[0058] When this embodiment is implemented, the gear 314 is driven to rotate by the lifting motor, and then the gear 314 and the climbing rack 313 cooperate to drive the lifting cylinder 312 to climb upward relative to the guide rod 311, and multiple lifting cylinders 312 move upward synchronously, and the converter station 8 is driven to move upward through the bearing member 32; when it moves to a predetermined height, the lifting motor is controlled to stop working (the lifting motor should be a motor with a self-locking function when power is off), and at this time, the locking rack 315 is driven by the telescopic rod 316 to move toward the climbing rack 313, so that the locking rack 315 is meshed with the climbing rack 313, thereby locking the lifting cylinder 312; in order to facilitate observation of the locking rack 315 and the climbing rack 313, In order to monitor the position of the lifting rack 315, an observation window can be provided on the outer wall of the lifting cylinder 312 (the through window is correspondingly arranged at the position of the locking rack 315), and a camera is arranged on the observation window to shoot the position of the locking rack 315 and the climbing rack 313. When the converter station 8 approaches the predetermined height position, the corresponding position of the locking rack 315 and the climbing rack 313 is observed in real time by the camera. When the teeth on the locking rack 315 and the teeth on the climbing rack 313 are in a corresponding state, the lifting motor is controlled to stop working. At this time, the locking rack 315 is driven to move toward the climbing rack 313 by the telescopic rod 316, so that the teeth on the locking rack 315 can be engaged with the teeth on the climbing rack 313, thereby achieving a locking effect.

[0059] In some embodiments of the present application, Figure 2As shown, the floating offshore converter station transportation equipment also includes a mooring connector 5 (the mooring connector 5 in this solution is configured as a pulley, and the pulley is installed on the outer peripheral wall of the floating part 2), and a plurality of mooring connectors 5 are provided, and the plurality of mooring connectors 5 are spaced around the axial center line of the floating part 2; the mooring connector 5 is connected to the outer peripheral wall of the floating part 2, and the mooring connector 5 is used to connect with the anchor chain 6; in the process of shipping the converter station 8 to the predetermined sea area, one end of the anchor chain 6 is connected to the mooring connector 5 (pulley), and the other end of the anchor chain 6 is connected to the tugboat (there are a plurality of tugboats in this solution, one of which is used for shipping, and the remaining tugboats are used to control the heading of the transportation equipment during the shipping process), thereby ensuring the stability of the overall structure of the transportation equipment during the shipping process.

[0060] After the converter station 8 is shipped to the predetermined sea area, during the process of the shipping part 1 sinking into the water, the coordination between multiple anchor chains 6 can be used to dynamically adjust the posture of the converter station 8, thereby ensuring that the inclination angle of the converter station 8 meets the design requirements and ensuring the construction safety during the installation process; finally, by connecting the anchor chain 6 and the foundation preset on the seabed in advance, the floating part 2 can be positioned, and the converter station 8 can be positioned at the predetermined sea area.
