Description

Technical Field

[0001] The utility model relates to the field of offshore building protection equipment, in particular to an improved ship-supporting component protection device for an offshore platform. Background Art

[0002] The energy efficiency of offshore wind power resources is higher than that of land wind farms, so offshore wind power is one of the key areas for the development of renewable energy. However, offshore wind power facilities face a harsh marine corrosion environment. Although the berthing parts have been treated with anti-corrosion, wind turbines and booster stations often berth at ships, and the berthing of ships will cause damage to the paint coating of the berthing parts. Under the long-term effects of severe marine atmospheric corrosion, marine biological erosion, wave impact, and other factors, wind power equipment and equipment will be corroded and damaged and lose their functions, shortening their service life and leading to the early retirement of wind power equipment. In severe cases, corrosion safety accidents may also occur. Utility Model Content

[0008] Optionally, the depth of the limiting groove is greater than the thickness of the fastener.

[0009] Optionally, the fastener is a steel wire with a U-shaped structure.

[0010] Optionally, the material of the steel wire is 316L stainless steel.

[0011] Optionally, the material of the anti-collision plate is polyethylene.

[0012] The improved ship-supporting protection device for an offshore platform of the utility model has the following advantages:

[0013] (1) Several anti-collision plates are fixed to the columns uniformly by multiple fasteners. The installation method is simple and reduces the difficulty of offshore operations. Several anti-collision plates are independent of each other and can be partially replaced according to the degree of damage of the anti-collision plates, effectively reducing maintenance costs.

[0014] (2) The buffer layer can effectively absorb the impact of a ship collision and prevent the column from deforming.

[0015] (3) The limit plate can limit the up and down displacement of the anti-collision plate to prevent the anti-collision plate from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 5 As shown, an improved ship-mooring protection device for an offshore platform includes columns 1 and a plurality of vertically arranged anti-collision plates 2 arranged on both sides of a ladder. Both the columns 1 and the anti-collision plates 2 are surface pretreated and coated with anti-corrosion paint. The material of the anti-collision plates 2 is polyethylene, which has the properties of corrosion resistance, aging resistance, high strength and high wear resistance. In this embodiment, fifteen anti-collision plates 2 are used. The anti-collision plates 2 are arranged in a semicircular structure and attached to the surface of the column 1. A buffer layer 3 is arranged between the anti-collision plates 2 and the column 1. The buffer layer 3 can effectively absorb the impact of the ship on the column 1 and prevent the column 1 from deforming. The upper and lower parts of the column 1 are respectively fixedly connected with a limiting plate 4. The anti-collision plate 2 is located between the two limiting plates 4. The limiting plate 4 can limit the up and down displacement of the anti-collision plate 2 to prevent the anti-collision plate 2 from falling off and improve the stability of the protective device. The width of the limiting plate 4 is less than the thickness of the anti-collision plate 2 to prevent the ship from hitting the limiting plate 4 and causing damage.

[0023] The anti-collision plate 2 is evenly provided with a plurality of horizontal limiting grooves 5, each limiting groove 5 is provided with a fastener 6, the fastener 6 is a U-shaped steel wire, the material of the steel wire is 316L stainless steel, which has good corrosion resistance and high strength, and the two sides of the column 1 are provided with fixing plates 7 for fixing the fastener 6, and the fastener 6 is fixedly connected to the fixing plate 7 by bolts. The depth of the limiting groove 5 is greater than the diameter of the fastener 6, so that the fastener 6 will be hidden in the limiting groove 5, so as to prevent the ship from hitting the fastener 6 when approaching, thereby affecting the stability of the anti-collision plate 2.

[0024] Before installing the protective device, pre-treat the surface of the column 1 to remove debris, marine organisms, microorganisms and floating rust on the surface of the column 1, and then apply anti-corrosion paint on the surface of the column 1 and the anti-collision plate 2. During installation, first install the buffer layer 3 on the surface of the column 1. The buffer layer 3 is made of rubber material and has a good protective effect. Then install the anti-collision plate 2 outside the buffer layer 3. The anti-collision plate 2 is tied and fixed by fasteners 6. The thickness of the anti-collision plate 2 needs to reach 50mm, the protection length needs to reach 5 meters, and the protection width must at least wrap more than half of the area of ​​the column 1, which can meet the service life of 3000 times. The protective device has a simple structure and convenient installation. It can be partially replaced according to the damage during maintenance, which greatly reduces the maintenance difficulty of the docking parts and the work risks of the operation and maintenance personnel.

[0025] The embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.
