Description

Technical Field

[0001] This utility model relates to the field of marine engineering platform technology, and in particular to a corrosion-resistant shell structure for marine engineering platforms. Background Technology

[0002] Marine engineering refers to new construction, reconstruction, and expansion projects aimed at developing, utilizing, protecting, and restoring marine resources, with the main body of the project located on the seaward side of the coastline. Generally, the main contents of marine engineering can be divided into two parts: resource development technology and equipment and facility technology. Marine engineering platforms are often built on the sea surface, which requires a corrosion-resistant shell structure for marine engineering platforms.

[0003] In existing technologies, corrosion protection of traditional marine engineering platforms mainly relies on epoxy resin coatings and sacrificial anode cathodic protection technology. However, the supports of traditional marine engineering platforms are basically immersed in seawater, and the epoxy coating is prone to micro-cracks in the splash zone due to mechanical erosion, resulting in a short protection life.

[0004] To address this issue, a corrosion-resistant hull structure for marine engineering platforms is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant shell structure for a marine engineering platform, comprising: a support body, wherein two protective devices are provided on the surface of the support body, the interior of each of the two protective devices is filled with filler, and multiple buffer devices are provided on the surface of each of the two protective devices.

[0007] Furthermore, multiple T-shaped mounting plates are fixedly installed on the surface of the support body.

[0008] Furthermore, the protective device includes an arc-shaped hollow protective shell, with two T-shaped mounting slots on the inner side of the arc-shaped hollow protective shell. The bottom of the upper T-shaped mounting slot has a movable slot, and multiple metal support rods are fixedly embedded inside the arc-shaped hollow protective shell.

[0009] Furthermore, the outer surface of the arc-shaped hollow protective shell is coated with an antibacterial layer, and the inner surface of the arc-shaped hollow protective shell is coated with a plasma-polymerized coating.

[0010] Furthermore, the antibacterial layer is coated with a nano-silver coating.

[0011] Furthermore, the plasma polymerization coating is an iridium-tantalum coating.

[0012] Furthermore, the filler is used to fill the interior of the arc-shaped hollow protective shell, and the filler is a coke-gypsum composite filler.

[0013] Furthermore, the buffer device includes a protective plate, on the inner side of which multiple springs are fixedly installed. Each of the multiple springs has a damper movably embedded inside it. One end of each of the multiple dampers is fixedly installed on the inner side of the protective plate, and the other end of each of the multiple springs and the multiple dampers is fixedly installed on the outer surface of the arc-shaped hollow protective shell.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. Before installation and use, this utility model requires pre-embedded T-shaped mounting plates on the surface of the support body for installing the arc-shaped hollow protective shell. Insert the upper T-shaped mounting plate into the movable groove, and place the lower one at the bottom of the T-shaped mounting groove. Then, insert them into the two T-shaped mounting grooves respectively for fixed installation. The scouring and splashing of waves will first impact the surface of the protective plate and be buffered by springs and dampers, reducing the impact on the support body and enhancing the service life of the protection.

[0016] 2. In this utility model, an antibacterial layer is coated on the outside of the arc-shaped hollow protective shell. The antibacterial layer uses a nano-silver coating to inhibit the adhesion and metabolic corrosion of microorganisms and extend the maintenance cycle. The inside of the arc-shaped hollow protective shell is coated with a plasma polymerization coating using an iridium-tantalum coating. A dense inert film is formed through atomic-level deposition to increase the pitting potential of stainless steel. Combined with an electromagnetic energy storage device, dynamic potential compensation is achieved. In addition, the metal support rods filled inside the arc-shaped hollow protective shell reduce resistance and potential fluctuations, making the current distribution more uniform.

[0027] In one embodiment, a plurality of T-shaped mounting plates 101 are fixedly mounted on the surface of the support body 1.

[0028] Specifically, such as Figure 2 As shown: T-shaped mounting plate 101 is used to support and install the arc-shaped hollow protective shell 201.

[0029] In one embodiment, the protective device 2 includes an arc-shaped hollow protective shell 201, with two T-shaped mounting slots 202 opened on the inner side of the arc-shaped hollow protective shell 201. The bottom of the upper T-shaped mounting slot 202 is provided with a movable slot 203, and a plurality of metal support rods 204 are fixedly embedded inside the arc-shaped hollow protective shell 201.

[0030] Specifically, such as Figure 1 , 3As shown in Figures 4 and 5: The T-shaped mounting groove 202 is fitted onto the surface of the T-shaped mounting plate 101 for installing the arc-shaped hollow protective shell 201, facilitating future replacement and maintenance. The movable groove 203 facilitates the insertion of the T-shaped mounting plate 101, allowing the arc-shaped hollow protective shell 201 to fit against the support body 1, and then the T-shaped mounting plate 101 can be easily inserted into the T-shaped mounting groove 202. The metal support rod 204 strengthens the internal support of the arc-shaped hollow protective shell 201.

[0031] In one embodiment, the outer surface of the arc-shaped hollow protective shell 201 is coated with an antibacterial layer 5, and the inner surface of the arc-shaped hollow protective shell 201 is coated with a plasma polymerization coating 6.

[0032] Specifically, such as Figure 1 , 3 As shown in Figures 4 and 5: the antibacterial layer 5 enhances the inhibition of microbial adhesion and metabolic corrosion, and the plasma polymer coating 6 achieves dynamic potential compensation, reducing the fluctuation range of the potential.

[0033] In one embodiment, the antibacterial layer 5 is made of nano-silver coating.

[0035] In one embodiment, the plasma-polymerized coating 6 is an iridium-tantalum coating.

[0036] Specifically, such as Figure 4-5 As shown: The iridium-tantalum coating forms a dense inert film through atomic-level deposition, which raises the pitting potential of 316L stainless steel to above 1.2V, and achieves dynamic potential compensation by combining it with an electromagnetic energy storage device.

[0037] In one embodiment, the filler 3 is filled inside the arc-shaped hollow protective shell 201, and the filler 3 is a coke-gypsum composite filler.

The upper T-shaped mounting plate 101 is inserted into the movable groove 203, and the lower one is placed at the bottom of the T-shaped mounting groove 202. Then, it is inserted into the two T-shaped mounting grooves 202 respectively for fixed installation. The scouring and splashing of waves will first impact the surface of the protective plate 401, and be buffered by the spring 402 and damper 403, reducing the impact on the support body 1 and enhancing the service life of the protection. The outer side of the arc-shaped hollow protective shell 201 is coated with an antibacterial layer 5, which uses a nano-silver coating to inhibit microbial adhesion and metabolic corrosion, extending the maintenance cycle. The inner side of the arc-shaped hollow protective shell 201 is coated with a plasma polymerization coating 6, which uses an iridium-tantalum coating to form a dense inert film through atomic-level deposition, increasing the pitting potential of stainless steel. Combined with an electromagnetic energy storage device, dynamic potential compensation is achieved. In addition, the metal support rod 204 filled inside the arc-shaped hollow protective shell 201 reduces resistance and potential fluctuations, making the current distribution more uniform.
