The terms "first" and "second" and the like are used to distinguish one element from another and do not have order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0020] According to the specific implementation scheme provided by the present disclosure, Figures 1 to 5 As shown in the figure, a hanging cover 100 is provided, and the hanging cover 100 is used for an offshore substation 200. The offshore substation 200 includes a main body 210 and a top plate 220. The top plate 220 is supported on the main body 210 and surrounds a hanging cover space 230. The hanging cover 100 includes a plurality of panels 110 and a connecting assembly 120. The panels 110 are at least partially supported on the main body 210. The connecting assembly 120 is used to connect two adjacent panels 110 to form a hanging cover plate. The connecting assembly 120 is also used to connect the hanging cover plate and the top plate 220 to seal the hanging cover space 230, wherein the hanging cover plate is arranged flush with the top surface of the top plate 220.

[0021] Through the above technical solution, in the hanging cover 100 provided by the present disclosure, the hanging cover 100 includes a plurality of panels 110, and the plurality of panels 110 are connected through a connecting assembly 120 to form a hanging cover plate, and the hanging cover plate is connected to the top plate 220 of the offshore booster station 200 through the connecting assembly 120, so that when the hanging cover 100 needs to be removed during the actual maintenance process, the hanging cover 100 can be removed by simply disassembling the connecting assembly 120, thereby reducing the difficulty of maintenance. Among them, the plurality of panels 110 are assembled into a hanging cover plate through the connecting assembly 120, so that the staff can transport the panels 110 to the position where the hanging cover plate needs to be installed, and then assemble the plurality of panels 110 through the connecting assembly 120 to form a hanging cover plate, thereby reducing the difficulty of transporting the hanging cover 100. In addition, a top plate 220 is supported on the main body 210, and because the panel 110 is at least partially supported on the main body 210, the cover plate and the top plate 220 can be in the same horizontal plane, thereby solving the problem of the protruding roof of the offshore substation 200 and the limited escape route, and effectively improving the safety of the roof of the offshore substation 200.

[0022] In the suspension cover provided by the present disclosure, the connection assembly 120 can be constructed in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 2 and Figure 4 As shown in , the connection assembly 120 may include a connection plate 121, a first joint seam 151 is formed between the panel 110 and the top plate 220, the connection plate 121 may be covered on the first joint seam 151, and the connection plate 121 is fixedly connected to the main body 210 through a plurality of fasteners 122, so as to clamp the panel 110 and the top plate 220 between the connection plate 121 and the main body 210. That is, in actual use, it is difficult for the panel 110 and the top plate 220 to fit completely together, the connection plate 121 is covered on the first joint seam 151, that is, the connection plate 121 is laid on the top plate 220 and the panel 110, and by fixing the connection plate 121 to the main body 210, the positions of the top plate 220 and the panel 110 are clamped between the connection plate 121 and the main body 210, and the connection between the top plate 220 and the panel 110 is achieved at the same time. In the present disclosure, there are multiple fasteners 122, and the multiple fasteners 122 are arranged at intervals along the extension direction of the connecting plate 121, and each fastener 122 is fixed to the main body 210 through the first connecting seam 151, and finally the position of the top plate 220 and the panel 110 is clamped and fixed, thereby avoiding the need to open holes in the top plate 220 and the panel 110, and improving the sealing of the connection between the panel 110 and the top plate 220.

[0023] In the practical application of the above embodiment, in order to improve the reliability and sealing of the connection between the top plate 220 and the panel 110, the first joint 151 can be filled with sealant 310 to prevent rainwater from flowing into the offshore booster station 200 through the gap between the top plate 220 and the panel 110, causing damage to the internal electrical devices. In addition, the provision of the sealant 310 can also improve the reliability of the connection between the panel 110 and the top plate 220 and increase the reliability of the fixation of the panel 110. In the actual construction process, the staff can first position the panel 110 to determine the position of the first joint 151, and then pass one end of the fastener 122 through the first joint 151 to fix it to the main body 210, and then pour the sealant 310 into the first joint 151. After the sealant 310 solidifies, the connecting plate 121 is covered on the first joint 151 and fixed by the fastener 122 to achieve a sealed connection between the top plate 220 and the panel 110. In addition, the panel 110 is also provided with a lifting lug 111 , so that the panel 110 can be lifted by the lifting lug 111 in practical applications.

[0024] In some other embodiments, the plurality of fasteners 122 may also be arranged in two rows along the axial direction of the connecting plate 121, and the two rows of fasteners 122 are parallel to each other, wherein one row of fasteners 122 are respectively passed through the top plate 220 to fix the top plate 220 to the main body 210, and the other row of fasteners 122 are respectively passed through the panel 110 to fix the panel 110 to the main body 210, which can also achieve the fixation of the position of the top plate 220 and the panel 110, and the present disclosure does not make any specific restrictions on this.

[0025] In the suspension cover provided by the present disclosure, in order to further achieve the sealing of the connection between the panel 110 and the top plate 220, as an exemplary embodiment, reference is made to Figure 3 and Figure 4 As shown in , the hanging cover 100 may include a sealing component 130, which may be buckled above the connecting component 120 to form a sealed space, in which the connecting component 120 is accommodated, and the sealing component 130 is fixed to the top plate 220 and the panel 110 to seal the connecting component 120. In other words, the sealing component 130 is arranged at the connection between the top plate 220 and the panel 110, that is, at the location where the connecting component 120 is located, and the sealing component 130 can provide a sealed space for accommodating the connecting component 120 for isolating the connecting component 120 from external conditions, and preventing rainwater and the like from directly contacting the connecting component 120, causing a seal failure.

[0026] Based on the above embodiments, the sealing assembly 130 can be constructed in any suitable form to achieve sealing of the connecting assembly 120, and the present disclosure does not impose any specific limitation on this. Figure 3As shown in, the sealing assembly 130 may include a first upright plate 131, a second upright plate 132 and a cover plate 133. The first upright plate 131 and the second upright plate 132 may be respectively arranged on both sides of the connecting assembly 120. The first upright plate 131 is fixed to the top plate 220, and a first support plate 1311 is arranged on the side of the first upright plate 131 facing the second upright plate 132. The second upright plate 132 is fixed to the panel 110, and a second support plate 1321 is arranged on the side of the second upright plate 132 facing the first upright plate 131. The cover plate 133 may be supported on the first support plate 1311 and the second support plate 1321 and be detachably fixed to the first upright plate 131 and the second upright plate 132. Among them, the first vertical plate 131 and the second vertical plate 132 can be fixed to the panel 110 and the top plate 220 by welding or the like, and the cover plate 133 can be installed or removed relative to the first vertical plate 131 and the second vertical plate 132. In this way, when the hanging cover 100 provided by the present invention needs to be removed during actual maintenance, it is only necessary to remove the cover plate 133 from the first vertical plate 131 and the second vertical plate 132, and the first vertical plate 131 and the second vertical plate 132 can be separated as the top plate 220 is detached from the panel 110. While ensuring the sealing effect, the problem of poor restoration convenience of the hanging cover 100 is further solved, and the difficulty of maintenance of the panel 110 is reduced.

[0027] The cover plate 133 can be detachably fixed to the first vertical plate 131 and the second vertical plate 132 in any suitable manner, and the present disclosure does not impose any specific restrictions on this. Figure 3 As shown in the figure, the first support plate 1311 and the second support plate 1321 can be provided with anti-slip rubber 320, and the cover plate 133 is pushed between the first vertical plate 131 and the second vertical plate 132 by pressing. The anti-slip rubber 320 is compressed and squeezes both sides of the cover plate 133 at the same time, so as to achieve the fixation of the cover plate 133 without welding and opening, thereby ensuring the sealing performance of the sealing assembly 130 and facilitating removal.

[0028] In the suspension cover provided in the present disclosure, in order to further improve the reliability of the suspension cover 100 when installed on the offshore booster station 200, as an exemplary embodiment, reference is made to Figure 2As shown in , the hanging cover 100 may further include a support assembly 140, which may include a hanging cover beam 141 and an extension plate 142. The extension plate 142 may be arranged parallel to the panel 110 and fixed to the main body 210, and the hanging cover beam 141 may be supported between the extension plate 142 and the panel 110. That is, an extension plate 142 spaced apart from and parallel to the top plate 220 is provided on the main body 210, and the extension plate 142 is used to provide a setting platform for the hanging cover beam 141, so that the hanging cover beam 141 supports the panel 110, and the two ends of the hanging cover beam 141 are respectively in contact with the extension plate 142 and the panel 110, so that the panel 110 is supported on the extension plate 142 through the hanging cover beam 141, wherein the height of the hanging cover beam 141 may match the length of the extension plate 142 from the top plate 220, so that the panel 110 is located at the same horizontal plane as the top plate 220 after being supported by the hanging cover beam 141.

[0029] Based on the above embodiment, the shape of the suspension beam 141 can be designed to be any suitable shape, and the present disclosure does not impose any specific limitation on this. Figure 2 As shown in , the hanging cap beam 141 can be constructed as an I-beam, which includes a vertical plate and two horizontal plates respectively connected to both ends of the vertical plate, one of the two horizontal plates is supported on the extension plate 142, and the other is used to support the panel 110. In this way, the hanging cap beam 141 can reduce its own weight as much as possible while ensuring the contact area between the panel 110 and the extension plate 142, further improving the reliability of installation on the extension plate 142.

[0030] In the suspension cover provided in the present disclosure, in order to further improve the convenience of installation of the suspension cover 100, as an exemplary embodiment, reference is made to Figure 2 As shown in , a positioning plate 143 may be provided at one end of the extension plate 142 away from the main body 210, and the positioning plate 143 may be arranged perpendicular to the extension plate 142. The provision of the positioning plate 143 can facilitate confirmation of the installation position of the suspension cap beam 141. Specifically, after the extension plate 142 is fixed to the main body 210, the positioning plate 143 is provided at a suitable position on the extension plate 142, and an installation space for the suspension cap beam 141 to be installed is formed between the positioning plate 143 and the main body 210, which facilitates confirmation of the installation position of the suspension cap beam 141.

[0031] In order to further improve the sealing performance of the cover 100 to the cover space 230 of the offshore booster station 200, as an exemplary embodiment, reference is made to Figure 2 and Figure 5As shown in , the positioning plate 143 can be arranged along the circumference of the main body 210 to form a waterproof space 144 together with the main body 210. In this way, when the connection assembly 120 and the sealing assembly 130 fail, rainwater first falls into the waterproof space 144 formed by the positioning plate 143 and the main body 210, and cannot directly enter the interior of the offshore booster station 200, thereby improving the sealing performance of the suspension cover 100 to the suspension cover space 230, thereby improving the waterproof performance of the offshore booster station 200.

[0032] In the suspension cover provided in the present disclosure, in order to further improve the reliability of the suspension cover 100 when installed on the offshore booster station 200, as an exemplary embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 As shown in , two adjacent panels 110 can be at least partially supported on the same suspension beam 141, a second joint seam 152 can be formed between the two adjacent panels 110, the connecting plate 121 can be covered on the second joint seam 152, and the connecting plate 121 can be fixedly connected to the suspension beam 141 by a plurality of fasteners 122, so as to clamp the two adjacent panels 110 between the connecting plate 121 and the suspension beam 141. In other words, the panels 110 are also supported on the extension plate 142 through the suspension beam 141. In the present disclosure, since the extension plate 142 is arranged around the main body 210, when the installation position of the suspension beam 141 is close to the main body 210, the suspension beam 141 can be supported as a whole on the extension plate 142 and extend along the axial direction of the extension plate 142 (refer to Figure 2 When the location of the hanging cover beam 141 is far from the main body 210, the two ends of the hanging cover beam 141 can also be respectively placed on the two opposite sides of the extension plate 142 (refer to Figure 5 ), so as to support the end of the panel 110 away from the main body 210. The arrangement of two adjacent panels 110 supported on the same suspension beam 141 can make the second joint seam 152 formed on a certain suspension beam 141, rather than between two adjacent suspension beams 141. In this way, the position of the second joint seam 152 does not overlap with the gap between two adjacent suspension beams 141, which makes it easier for workers to pour sealant 310 into the second joint seam 152, and the gap between two adjacent suspension beams 141 can also be covered by the panel 110 (refer to Figure 4 As shown in the figure, the arrangement of the cover beam 141 can not only provide support for the panel 110 to ensure the reliability of the installation of the cover 100 on the offshore substation 200, but also further improve the sealing performance of the cover space 230 of the offshore substation 200 by the cover 100.

[0033] Similarly, a sealing assembly 130 may also be arranged above the connecting assembly 120 for connecting two adjacent panels 110. The first vertical plate 131 and the second vertical plate 132 of the sealing assembly 130 are respectively arranged on the two panels 110, and a first support plate 1311 and a second support plate 1321 are also arranged. The cover plate 133 is supported on the first support plate 1311 and the second support plate 1321 and fixed between the first vertical plate 131 and the second vertical plate 132 to provide further sealing for the second connecting seam 152 and the connecting assembly 120.

[0034] On the basis of the above technical solution, the present disclosure further provides an offshore booster station 200, including the above-mentioned suspension cover 100, the main body 210 is provided with a first reinforcing rib 241, and a second reinforcing rib 242 is provided between the main body 210 and the extension plate 142 of the suspension cover 100. In this way, the first reinforcing rib 241 can increase the strength of the main body 210, so as to improve the reliability of the suspension cover 100 installed on the main body 210, and the second reinforcing rib 242 is arranged in a trapezoidal shape between the main body 210 and the extension plate 142, so as to provide support for the extension plate 142, and further improve the reliability of the suspension cover 100 installed on the main body 210. Among them, the suspension cover 100 has all the technical features of the above-mentioned suspension cover 100, so it is not repeated here.

[0035] In summary, when installing the hanging cover 100 provided by the present disclosure, firstly, the first reinforcing rib 241, the second reinforcing rib 242, the extension plate 142 and the positioning plate 143 in the hanging cover 100 are welded together with the main body 210, and at the same time, the first vertical plate 131 and the first supporting plate 1311 in the sealing assembly 130 are welded to the main body 210, and then the hanging cover beam 141 is hoisted to the extension plate 142 for installation, and the second vertical plate 132 and the second supporting plate 1321 are arranged on the panel 110, and the panel 110 is hoisted to the hanging cover beam 141 for installation, and the main body 210 and the hanging cover beam 141 are welded together. 1, the fastener 122 is installed, the sealant 310 is poured into the first joint seam 151 and the second joint seam 152, the connecting plate 121 is installed to compact the sealant 310 and the connecting plate 121 is fixed by the fastener 122 to achieve the connection between the top plate 220 and the panel 110 and between the panels 110 and 110, and finally, the anti-slip rubber 320 is arranged on the first support plate 1311 and the second support plate 1321, and the cover plate 133 is installed to squeeze the anti-slip rubber 320 to fix the cover plate 133 between the first vertical plate 131 and the second vertical plate 132, so as to finally achieve the detachable installation of the hanging cover 100.
