The components are easy to deform and crack, and have a short service life. Utility Model Content

By eliminating the pipes in the prior art and replacing the I-beams with T-beams, a plate frame structure composed of T-beams and plates is formed to enhance the strength and fatigue strength of the offshore converter station and reduce the weight of the converter station.

[0005] The utility model provides an offshore converter station with a plate frame structure, comprising: a plate, wherein the plate further comprises: a plate; a first beam, wherein a plurality of the first beams are fixedly connected to one side of the plate; a second beam, wherein a plurality of the second beams are fixedly connected between two of the first beams, and the second beams are used to form a force-bearing frame with the first beams; a third beam, wherein a plurality of the third beams are fixedly connected to one side of the plate, and the third beams are used to strengthen the strength of the plate; wherein the offshore converter station is composed of a plurality of the plates horizontally or vertically spliced ​​with each other.

[0006] Furthermore, the first beam also includes a first beam first portion and a first beam second portion, both of which are rectangular plates, the first beam first portion is fixedly connected to the center line of the first beam second portion along the length direction of the first beam second portion, and the first beam first portion and the first beam second portion form a T-shaped structure.

[0007] Furthermore, the second beam also includes a first portion of the second beam and a second portion of the second beam, both of which are rectangular plates, the first portion of the second beam is fixedly connected to the center line of the second portion of the second beam along the length direction of the second portion of the second beam, and the first portion of the second beam and the second portion of the second beam form a T-shaped structure.

[0008] Furthermore, the third beam also includes a first portion of the third beam and a second portion of the third beam, both of which are rectangular plates, and the edges of the first portion of the third beam in the length direction are fixedly connected to the edges of the second portion of the third beam in the length direction, and the first portion of the third beam and the second portion of the third beam form an L-shaped structure.

[0009] Furthermore, the first beam is fixedly connected along the side of the plate, and the first beam and the side of the plate are equal in length.

DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] like Figure 1-3 As shown, an offshore converter station with a plate frame structure includes: a plate 1 and a lifting lug 2, wherein the lifting lug 2 is arranged on the plate 1 at the top of the offshore converter station to facilitate lifting. The plate 1 also includes:

[0021] The plate 11 is rectangular and is used to form a deck or wall of an offshore converter station.

[0022] A first beam 12, a plurality of the first beams 12 are fixedly connected to one side of the plate 11. The first beam 12 also includes a first beam first portion 121 and a first beam second portion 122. The first beam first portion 121 and the first beam second portion 122 are both rectangular plates. The first beam first portion 121 is fixedly connected to the center line of the first beam second portion 122 along the length direction of the first beam second portion 122. The first beam first portion 121 and the first beam second portion 122 form a T-shaped structure. The first beam 12 is fixedly connected along the side of the plate 11. The first beam 12 and the side of the plate 11 are equal in length, so that the first beams 12 of each plate 1 can be fixedly connected to each other to transfer load.

[0023] The second beam 13, a plurality of the second beams 13 are fixedly connected between two of the first beams 12, and the second beam 13 is used to form a force-bearing frame with the first beam 12 to jointly bear the lateral and longitudinal loads. The second beam 13 also includes a second beam first portion 131 and a second beam second portion 132, the second beam first portion 131 and the second beam second portion 132 are both rectangular plates, the second beam first portion 131 is fixedly connected to the center line of the second beam second portion 132 along the length direction of the second beam second portion 132, and the second beam first portion 131 and the second beam second portion 132 form a T-shaped structure. The second beam 13 is perpendicular to the first beam 12. The distance between the beams of the second beam 12 is shorter than the distance between the beams of the first beam 11.

[0024] The third beam 14, several of the third beams 14 are fixedly connected to one side of the plate 11, and the third beam 14 is used to strengthen the strength of the plate 11 and prevent the plate 11 from deforming. The third beam 14 also includes a third beam first part 141 and a third beam second part 142, and the third beam first part 141 and the third beam second part 142 are both rectangular plates, and the length direction of the third beam first part 141 is fixedly connected to the length direction of the third beam second part 142, and the third beam first part 141 and the third beam second part 142 form an L-shaped structure. Several of the third beams 14 are fixedly connected between two second beams 13, and the third beams 14 are perpendicular to the second beams 13, which further strengthens the strength of the plate frame structure, and the distance between the beams of the third beams 14 is shorter than the distance between the beams of the second beams 13. The width of the first beam 12 is larger than that of the second beam 13, and the width of the second beam 13 is larger than that of the third beam 14, which is conducive to further reducing the weight.

[0025] The offshore converter station is composed of a plurality of plates 1 that are horizontally or vertically spliced ​​with each other.

[0026] The first beam 12 and the second beam 13 are T-shaped beams in order to reduce weight compared with the I-beams in the prior art, and the third beam 14 is L-shaped beam because the third beam 14 is different from the first beam 12 and the second beam 13 and does not need to bear transverse and longitudinal loads, but strengthens the strength of the plate 11 to prevent the plate 11 from deforming and prematurely causing metal fatigue.

[0027] By eliminating the pipes in the prior art and replacing the I-beams with T-shaped first beams 12 and second beams 13, a plate frame structure consisting of the first beam 12, the second beam 13 and the plate 11 is formed. Since the prior art mainly relies on pipes to support the lateral and longitudinal strength, the present solution disperses the stress to each plate 1 constituting the offshore converter station through the plate frame structure, which is more conducive to enhancing the strength and fatigue resistance of the offshore converter station. At the same time, the weight of the converter station can be reduced due to the elimination of pipes and I-beams.

[0028] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
