DETAILED DESCRIPTION

[0025] The specific embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0026] As shown in Figures 1 to 5 , the preferred embodiment of the present application provides a platform module docking twist lock device, which comprises a first connecting structure and a second connecting structure, the first connecting structure and the second connecting structure are respectively arranged on a first platform module 1 and a second platform module 2, and the first connecting structure cooperates with the second connecting structure to connect the two platform modules.

[0027] The first connecting structure comprises a plug block 3, the side of the plug block 3 is provided with a first limiting structure 5, the first limiting structure 5 comprises a first locking member 51 and a first driving member 52, the first driving member 52 is used to drive the first locking member 51 to move away from the plug block 3 to abut against the second connecting structure;

[0028] The second connecting structure comprises a plug slot 4, the plug slot 4 is provided with a second limiting structure 6 corresponding to the first limiting structure 5, and the second limiting structure 6 comprises a second locking member 61;

[0029] The first locking member 51 comprises a movable plate 511, the side of the movable plate 511 away from the plug block 3 is provided with a plurality of first engaging teeth 512 extending in the vertical direction, the second locking member 61 is provided with a second engaging tooth 611 corresponding to the first engaging tooth, and the plurality of first engaging teeth 512 and the corresponding second engaging tooth 611 are engaged.

[0030] Specifically, in the traditional construction scheme, the various platform modules of the converter station are greatly affected by external wind and waves during installation, and the platform modules are prone to positional deviation before installation is completed. During installation, workers have to additionally expend effort to ensure the stability of the relative positions of the platform modules, so that the platform modules can be stably installed. This scheme not only consumes time and effort, is complex in construction, and is low in construction efficiency, but also easily affects the stability and firmness of the structure after installation of the platform modules. In the present embodiment, however, first and second connecting structures are arranged on the first and second platform modules 1 and 2 to be connected, wherein the main body of the first connecting structure is a plug 3, and the main body of the second connecting structure is a slot 4. The first and second platform modules 1 and 2 can be preliminarily connected through cooperation of the plug 3 and the slot 4. When facing the influence of external wind and waves, the first and second platform modules 1 and 2 can move synchronously, so as to avoid deviation of the relative positions between the two platform modules, and finally facilitate the subsequent fixed connection work between the two platform modules and improve the work efficiency of the fixed connection. Further, in the present embodiment, the first connecting structure is further provided with a first locking member 51 and a first driving member 52. The first driving member 52 can be a motor structure or a hydraulic structure or a pneumatic structure, as long as it can drive the locking member to move toward the second locking member 61 of the second connecting structure. Meanwhile, the first and second locking members 51 and 61 are further provided with first and second meshing teeth 512 and 611 that mesh with each other. Through cooperation of the two meshing teeth and the first driving member 52, the connection between the first and second connecting structures can be more stable. When facing the influence of external wind and waves, the plug 3 is less likely to be separated from the slot 4. The robustness of the entire connecting structure is better, and the connection between the first and second platform modules 1 and 2 is more stable, which facilitates the subsequent fixed connection work between the two platform modules, reduces the subsequent construction difficulty, and improves the efficiency of the entire construction.

[0031] In some embodiments, a plurality of first connecting structures are arranged on the abutment plane of the first platform module 1, and a plurality of second connecting structures are arranged on the abutment plane of the second platform module 2 corresponding to the first connecting structures.

[0032] In some embodiments, the plug 3 is provided with a first limiting structure 5 on at least two oppositely arranged side edges, and the slot 4 is provided with a second limiting structure 6 on at least two oppositely arranged inner side walls.

[0033] In some embodiments, the first driving member 52 includes a first driving box 521 arranged on the side edge of the plug 3. A hydraulic push rod 522 is arranged in the first driving box 521. The output end of the hydraulic push rod 522 is connected with the movable plate 511 and drives the movable plate 511 to move away from or close to the plug 3.

[0034] Specifically, in the embodiment, the driving structure of the first driving member 52 is defined, the first driving box 521 is arranged between the plug-in block 3 and the first locking member 51, and the hydraulic push rod 522 is arranged in the driving box. The hydraulic push rod 522 can push the first engaging tooth 512 to move towards the direction of the second engaging tooth 611 through the movable plate 511, and make the first engaging tooth 512 engage with the second engaging tooth 611, so as to realize the stable butt joint of the first platform module 1 and the second platform module 2. Of course, in other embodiments, an electric linear push rod or a pneumatic push rod can also be arranged in the first driving box 521, and the hydraulic push rod 522 is adopted because the hydraulic push rod 522 can provide greater thrust and the thrust is more stable and reliable.

[0035] In some embodiments, the second limiting structure 6 further comprises a second driving member 62, and the second driving member 62 comprises a second driving box 621 fixedly arranged on the inner wall of the insertion slot 4. The second driving box 621 is connected with the second locking member 61 away from the inner wall of the insertion slot 4, and the second driving box 621 is used for driving the second locking member 61 away from or close to the plug-in block 3.

[0036] Specifically, in the embodiment, the second driving member 62 is further arranged between the second locking member 61 and the inner wall of the insertion slot 4, and the second driving member 62 can drive the second locking member 61 to be close to the first locking member 51. The cooperation of the first driving member 52 and the second driving member 62 can make the engagement between the first locking member 51 and the second locking member 61 more closely, so as to improve the stability of the connection between the two platform modules. In a specific embodiment, the second driving member 62 can also adopt the structure of the hydraulic push rod 522 to push the second locking member 61.

[0037] In addition, in a specific embodiment, the first driving box 521 is provided with a containing groove away from the plug-in block 3, the containing groove is fixedly connected with the first platform module 1, the movable plate 511 is contained in the containing groove, one end of the hydraulic push rod 522 is arranged in the containing groove and is fixedly connected with the movable plate 511 to drive the movable plate 511 to move. In another embodiment, the movable plate 511 is only fixedly connected with the output end of the hydraulic push rod 522.

[0038] In some embodiments, the movable plate 511 is connected with a plurality of first driving boxes 521 in the vertical direction; and the second locking member 61 is connected with a plurality of second driving boxes 621 in the vertical direction.

[0039] Specifically, considering that the movable plate 511 is arranged to extend in the vertical direction, the single first driving box 521 matched with the hydraulic push rod 522 is easy to make the force on the movable plate 511 unstable, and the local position of the movable plate 511 is subjected to excessive force, so a plurality of first driving boxes 521 are arranged on the side of the movable plate 511 close to the plug-in block 3, preferably three first driving boxes 521 are arranged at both ends of the movable plate 511 in the vertical direction and the middle of the movable plate 511, so as to ensure the stability of the force state of the movable plate 511.

[0040] In addition, in a specific embodiment, the first driving box 521 can be arranged on each of the four sides of the plug-in block 3 and connected with the first locking piece 51 through the first driving box 521, and correspondingly, the four inner side walls of the plug-in groove 4 can be connected with the second locking piece 61 through the second driving box 621, so as to further improve the stability of the connection between the first platform module 1 and the second platform module 2.

[0041] In some embodiments, the first locking piece 51 is provided with a pressure sensor 513 away from the side of the plug-in block 3, and the pressure sensor 513 is arranged between two adjacent first engagement teeth 512; the pressure sensor 513 is electrically connected with an alarm device 523 arranged in the first driving box 521.

[0042] Specifically, the pressure sensor 513 arranged between the first engagement teeth 512 can accurately monitor the pressure between the first locking piece 51 and the second locking piece 61, and a plurality of pressure sensors 513 can monitor the pressure on different positions of the first locking piece 51, and the position of the first locking piece 51 is adjusted by cooperating with the hydraulic push rod 522 in the plurality of first driving boxes 521, so that the pressure on the first locking piece 51 is more balanced and stable, and the displacement deviation between the first platform module 1 and the second platform module 2 during the docking process is compensated, so as to further ensure the stability and accuracy of the docking between the first platform module 1 and the second platform module 2.

[0043] In some embodiments, the cross section of the first engagement tooth 512 and the second engagement tooth 611 is an arc structure. Compared with the traditional rectangular engagement tooth structure, the arc-shaped engagement tooth can make the engagement between the first locking piece 51 and the second locking piece 61 more closely, the contact surface is larger, and the connection friction between the first engagement tooth 512 and the second engagement tooth 611 is larger, and the engagement state is more stable and reliable.

[0044] In some embodiments, electromagnetic strips 514 are provided between adjacent first meshing teeth 512 to magnetically connect the first and second meshing teeth 611. The provision of the electromagnetic strips 514 further enhances the stability of the connection between the first locking member 51 and the second locking member 61. Furthermore, during docking, the electromagnetic strips 514 help adjust the position of the first locking member 51 relative to the second locking member 61, thereby enabling faster and better meshing of the first and second meshing teeth 512 and 611.

[0045] In some embodiments, a storage tank 7, a pump, and a spray nozzle 8 are provided within the insert 3. The storage tank 7 is used to store lubricant, and the pump is used to pump the lubricant to the spray nozzle 8 for spraying. The pump can extract the lubricant from the storage tank 7 and spray it into the slot 4 with the spray nozzle 8, thereby removing salt and sediment from the first locking member 51 and the second locking member 61. This ensures a tight fit between the first locking member 51 and the second locking member 61, thereby ensuring the stability and reliability of the docking between the first platform module 1 and the second platform module 2, thereby reducing the difficulty of the subsequent fixed connection between the two platform modules and improving construction efficiency. Furthermore, the spray nozzle 8 can be independently provided outside the insert 3 or embedded directly into the insert 3, as long as it can achieve the desired flushing effect.

[0046] In summary, an embodiment of the present invention provides a platform module docking twist lock device, which can stably dock the first platform and the second platform together by cooperating with the first meshing teeth 512 on the first locking member 51 and the second meshing teeth 611 on the second locking member 61, thereby ensuring the stability of subsequent connection construction, reducing the difficulty of subsequent construction, and improving the efficiency of the entire construction process.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
