Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to an anti-corrosion grid for offshore wind power which is easy to install. Background Art

[0002] With the rapid development of the offshore wind power industry, the construction scale of offshore wind farms has continued to expand. In offshore wind power facilities, such as wind turbine foundations and offshore platforms, grids are often needed for protection, anti-slip, ventilation, etc. However, existing offshore wind power grids have some shortcomings: In the prior art, existing grids usually need to be fixed with multiple bolts or other connectors in offshore wind power facilities, which is inconvenient to install. Due to the limited offshore operating conditions, the installation process is complicated and time-consuming, which not only affects the construction progress of offshore wind power projects, but also increases the risks of installation personnel working at sea. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: an anti-corrosion grid for offshore wind power that is easy to install, comprising: a grid plate, the grid plate having connection holes around it, the grid plate serving as a basic bearing structure, the wall of which is pre-opened with connection holes for subsequent connection and coordination with other components; A connecting part, the outer side of the connecting part is slidably connected to the side wall of the grille plate through a slide groove, and the slide groove is opened in the wall of the grille plate, the connecting part includes an insert block, the inner wall of the insert block is threadedly connected with a positioning bolt, the inner side of the insert block is slidably connected to a limit block, and the outer side of the limit block is fixedly connected with an elastic plate. When the grille plate is cut due to actual installation requirements, the normal splicing of the grille plate can still be achieved by adjusting the spacing between the installation parts and the movable characteristics of the connecting part; The mounting part, the outer side of the mounting part is plugged into the inner side of the connecting part, the mounting part includes a shell, the outer side of the shell is fixedly connected with a sliding sleeve, the inner wall of the sliding sleeve is slidably connected with a sliding connecting plate, the inner wall of the shell is rotatably connected with positive and negative screw rods, both ends of the positive and negative screw rods are fixedly connected with knobs, the inner wall of the shell is fixedly connected with a limiting column, the outer wall of the limiting column is slidably connected with the limiting plate, and both sides of the shell are fixedly connected with plug rods. When the mounting part is in use, multiple mounting parts can be connected together for use. When connecting, the sliding connecting plate is connected to the shells in other mounting parts. The sliding connection plate can be slidable in the sliding sleeve by the design that the spacing between the shells can be adjusted.

[0004] Preferably, the outer wall of the plug block is slidably connected to the inner side of the slide groove, the outer side of the elastic plate is fixedly connected to the inner side of the plug block, and the plug block of the connection part is inserted along the slide groove provided on the side wall of the grille plate until the plug block reaches a suitable position. At this time, the connection part can be initially fixed to the grille plate by passing the positioning bolt through the connection hole and screwing it into the threaded hole on the inner wall of the plug block.

[0005] Preferably, the outer wall of the insertion rod is plugged into the inner wall of the insertion block, the outer side of the shell is rotatably connected to the outer side of the knob, the inner wall of the limit plate is threadedly connected to the outer wall of the forward and reverse screw rods, and the knob drives the forward and reverse screw rods to rotate on the inner wall of the shell; since the thread directions at both ends of the forward and reverse screw rods are opposite, when the forward and reverse screw rods rotate, the limit plates on both sides will slide along the surface of the limit column and approach each other.

[0006] Preferably, the outer wall of the limit plate is slidably connected to the outer wall of the insertion rod through a slot, and the slot is opened in the wall of the insertion rod, the outer wall of the limit plate is plugged into the inner wall of the insertion block through a limiting hole, and the limiting hole is opened in the wall of the insertion block, the outer wall of the limit plate is slidably connected to the inner side of the shell, and the two sides of the limit plate can pass through the limiting hole into the slot, further enhancing the connection strength between the mounting part and the connecting part.

[0007] Preferably, the outer wall of the limit block is clamped with the outer wall of the insertion rod through an arc groove, and the arc groove is opened in the wall of the insertion rod. When the insertion rod is fully inserted into the insertion block, the limit block will be clamped into the arc groove opened in the wall of the insertion rod under the action of the elastic restoring force of the elastic plate, thereby achieving preliminary fixation of the mounting part and the connecting part.

[0008] A production process for an offshore wind power anti-corrosion grid that is easy to install, comprising the following steps: Step 1: Mixing raw materials: Evenly mix unsaturated polyester resin, glass fiber yarn, aluminum hydroxide, color paste, ultraviolet absorber, methyl ethyl ketone peroxide and cobalt isooctanoate in a ratio of 35% unsaturated polyester resin, 33% glass fiber yarn, 28% aluminum hydroxide, 1% color paste, 0.15% ultraviolet absorber, 0.85% methyl ethyl ketone peroxide and 0.28% cobalt isooctanoate; Step 2: Molding: pour the glass fiber yarn into the production mold and lay it evenly, then evenly pour the material divided into barrels in step 3 on the laid glass fiber yarn layer to ensure that the material fully infiltrates the glass fiber yarn layer to form a composite material; then apply a pressure of 0.1-0.3MPa to the composite material after pouring to discharge the bubbles therein, and heat and solidify the composite material after pressure defoaming; then cool it to 60-80℃, take it out of the mold to obtain a grid plate; Step 3: Finishing: Cut, mill and drill the grating plate obtained in step 2, and cover and sand the surface of the plate; then conduct a comprehensive inspection, repair and finishing to obtain the final product.

[0009] The fiber-reinforced composite platform is made of high-performance glass fiber as the reinforcing material and unsaturated polyester resin as the matrix. It is processed and compounded through multiple processes. The fiber-reinforced composite platform has the advantages of light weight and high strength, corrosion resistance, non-slip safety, convenient transportation, and maintenance-free.

[0010] The beneficial effects of the present invention are as follows: 1. The present invention provides a connection part, inserts the plug rod into the plug block, and realizes the preliminary plugging of the installation part and the connection part. When the plug rod is fully inserted into the plug block, the outer wall of the limit block is clamped into the arc groove provided in the plug rod wall under the elastic restoring force of the elastic plate, thereby realizing the preliminary fixation of the installation part and the connection part, and preventing the plug rod from accidentally falling out of the plug block before the final installation operation is completed.

[0011] 2. The present invention sets a mounting part, and by rotating the knobs on both sides of the mounting part shell, the knobs drive the positive and negative screws to rotate on the inner wall of the shell; the limit plates on both sides slide along the surface of the limit column and approach each other, and at this time, the two sides of the limit plate pass through the limit hole into the card slot, further enhancing the connection strength between the mounting part and the connecting part, so that multiple grille plates can be assembled together through the connecting part and the mounting part.

[0012] 3. The present invention provides positioning bolts to insert the plug of the connection part along the slide groove provided on the side wall of the grille plate until the plug reaches a suitable position. At this time, the positioning bolts can be screwed into the threaded holes on the inner wall of the plug through the connection holes to achieve the initial fixation of the connection part on the grille plate, preventing it from accidentally sliding along the slide groove during the subsequent installation process, thereby ensuring the connection stability between the connection part and the grille plate.

[0013] 4. The present invention provides a sliding connecting plate to connect the sliding connecting plate with the shells in other mounting parts. The sliding connecting plate can be slidable in the sliding sleeve, so that the spacing between the shells is adjustable. When the grille plate is cut due to actual installation requirements, the normal splicing of the grille plate can still be achieved by adjusting the spacing between the mounting parts and the movable characteristics of the connecting part.

[0017] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides a technical solution: an anti-corrosion grid for offshore wind power that is easy to install, comprising: a grid plate 1, the grid plate 1 is provided with connection holes 3 around it, the grid plate 1 is used as a basic bearing structure, and the connection holes 3 are pre-opened in its wall for subsequent connection and coordination with other components; The connecting part 4, the outer side of the connecting part 4 is slidably connected to the side wall of the grille plate 1 through the slide groove 2, and the slide groove 2 is opened in the wall of the grille plate 1, the connecting part 4 includes an insert block 41, the inner wall of the insert block 41 is threadedly connected with a positioning bolt 42, the inner side of the insert block 41 is slidably connected to a limit block 43, and the outer side of the limit block 43 is fixedly connected with an elastic plate 44. When installing the connecting part 4, the insert block 41 of the connecting part 4 is inserted along the slide groove 2 opened on the side wall of the grille plate 1 until the insert block 41 reaches a suitable position. At this time, the positioning bolt 42 can be screwed into the inner wall threaded hole of the insert block 41 through the connecting hole 3 to achieve the initial fixation of the connecting part 4 on the grille plate 1, to prevent it from accidentally sliding along the slide groove 2 during the subsequent installation process, and to ensure the connection stability between the connecting part 4 and the grille plate 1; The mounting part 5, the outer side of the mounting part 5 is plugged with the inner side of the connecting part 4, the mounting part 5 comprises a housing 51, the outer side of the housing 51 is fixedly connected with a sliding sleeve 52, the inner wall of the sliding sleeve 52 is slidably connected with a sliding connecting plate 53, the inner wall of the housing 51 is rotatably connected with a positive and negative screw rod 55, the two ends of the positive and negative screw rod 55 are fixedly connected with a knob 54, the inner wall of the housing 51 is fixedly connected with a limiting column 56, the outer wall of the limiting column 56 is slidably connected with a limiting plate 57, the two sides of the housing 51 are fixedly connected with an insertion rod 50, the outer wall of the plug block 41 is slidably connected with the inner side of the slide groove 2, the outer side of the elastic plate 44 is fixedly connected with the inner side of the plug block 41, the insertion rod 50 of the mounting part 5 is aligned with the inner wall of the plug block 41 of the connecting part 4, and the insertion rod 50 is inserted into the plug block 41 to achieve the preliminary plugging of the mounting part 5 with the connecting part 4. In the process of inserting the insertion rod 50 into the plug block 41, the outer wall of the insertion rod 50 will interact with the limiting block 43 slidably connected to the inner side of the plug block 41. When the insertion rod 50 contacts the limit block 43, the limit block 43 will be squeezed to slide toward the inside of the insertion block 41. At this time, the elastic plate 44 will be elastically deformed. As the insertion rod 50 continues to be inserted, when the insertion rod 50 is completely inserted into the insertion block 41, the limit block 43 will be under the action of the elastic restoring force of the elastic plate 44, and its outer wall will be stuck in the arc groove 58 opened in the wall of the insertion rod 50, thereby achieving preliminary fixation of the mounting portion 5 and the connecting portion 4, preventing the insertion rod 50 from accidentally escaping from the insertion block 41 before the final installation operation is completed.

[0018] The outer wall of the insertion rod 50 is plugged into the inner wall of the insertion block 41, the outer side of the shell 51 is rotatably connected to the outer side of the knob 54, the inner wall of the limit plate 57 is threadedly connected to the outer wall of the positive and negative screw rods 55, the outer wall of the limit plate 57 is slidably connected to the outer wall of the insertion rod 50 through the card slot 59, and the card slot 59 is provided in the wall of the insertion rod 50, the outer wall of the limit plate 57 is plugged into the inner wall of the insertion block 41 through the limit hole 45, and the limit hole 45 is provided in the wall of the insertion block 41, the outer wall of the limit plate 57 is slidably connected to the inner side of the shell 51, the outer wall of the limit block 43 is snap-fitted to the outer wall of the insertion rod 50 through the arc groove 58, and the arc groove 58 is provided in the wall of the insertion rod 50, by rotating the knobs 54 on both sides of the shell 51 of the mounting part 5, the knobs 54 drive the positive and negative screw rods 55 to rotate on the inner wall of the shell 51; The thread directions of the two ends are opposite. When the forward and reverse screw rods 55 rotate, the limit plates 57 on both sides will slide along the surface of the limit column 56 and approach each other. At this time, the two sides of the limit plate 57 pass through the limit hole 45 and enter the card slot 59, further enhancing the connection strength between the mounting part 5 and the connecting part 4, so that multiple grille plates 1 can be assembled together through the connecting part 4 and the mounting part 5; multiple mounting parts 5 can be connected together for use, and when connecting, the sliding connecting plate 53 is connected to the shell 51 in other mounting parts 5. The sliding connecting plate 53 can be slidable in the sliding sleeve 52, so that the spacing between the shells 51 is adjustable. When the grille plate 1 is cut due to actual installation needs, the normal splicing of the grille plate 1 can still be achieved by adjusting the spacing between the mounting parts 5 and the movable characteristics of the connecting part 4.

[0019] Working principle: The grid plate 1 is used as the basic bearing structure, and connection holes 3 are pre-opened in its wall for subsequent connection and coordination with other components.

[0020] When installing the connection part 4, insert the plug 41 of the connection part 4 along the slide groove 2 provided on the side wall of the grille plate 1 until the plug 41 reaches a suitable position. At this time, the positioning bolt 42 can be screwed into the threaded hole on the inner wall of the plug 41 through the connection hole 3 to achieve the initial fixation of the connection part 4 on the grille plate 1, so as to prevent it from accidentally sliding along the slide groove 2 during the subsequent installation process, and ensure the connection stability between the connection part 4 and the grille plate 1; Then, align the insertion rod 50 of the installation part 5 with the inner wall of the plug block 41 of the connection part 4, and insert the insertion rod 50 into the plug block 41 to achieve preliminary plug-in connection between the installation part 5 and the connection part 4. In the process of inserting the insertion rod 50 into the plug block 41, the outer wall of the insertion rod 50 will interact with the limit block 43 that is slidably connected to the inner side of the plug block 41. When the insertion rod 50 contacts the limit block 43, it will squeeze the limit block 43 to make it slide toward the inner side of the plug block 41. At this time, the elastic plate 44 will undergo elastic deformation. As the insertion rod 50 continues to be inserted, when the insertion rod 50 is fully inserted into the plug block 41, the limit block 43 will be under the action of the elastic restoring force of the elastic plate 44, and its outer wall will be stuck into the arc groove 58 opened in the wall of the insertion rod 50, thereby achieving preliminary fixation of the installation part 5 and the connection part 4, and preventing the insertion rod 50 from accidentally falling out of the plug block 41 before the final installation operation is completed; Then, by rotating the knobs 54 on both sides of the shell 51 of the mounting part 5, the knobs 54 drive the forward and reverse screw rods 55 to rotate on the inner wall of the shell 51; since the thread directions at both ends of the forward and reverse screw rods 55 are opposite, when the forward and reverse screw rods 55 rotate, the limit plates 57 on both sides will slide along the surface of the limit column 56 and approach each other. At this time, the two sides of the limit plate 57 pass through the limit hole 45 and enter the card slot 59, further enhancing the connection strength between the mounting part 5 and the connecting part 4, so that multiple grille plates 1 can be assembled together through the connecting part 4 and the mounting part 5.

[0021] Among them, when the mounting part 5 is in use, multiple mounting parts 5 can be connected together for use. When connecting, the sliding connecting plate 53 is connected to the shell 51 in other mounting parts 5. The sliding connecting plate 53 can be slidably designed in the sliding sleeve 52, so that the distance between the shells 51 is adjustable. When the grille plate 1 is cut due to actual installation requirements, the normal splicing of the grille plate 1 can still be achieved by adjusting the distance between the mounting parts 5 and the movable characteristics of the connecting part 4.

[0022] Example 2: Please refer to Figure 1 - Figure 6 The present invention provides a technical solution: Based on the first embodiment, a production process of an anti-corrosion grid for offshore wind power that is easy to install includes the following steps: Step 1: Mixing raw materials: Evenly mix unsaturated polyester resin, glass fiber yarn, aluminum hydroxide, color paste, ultraviolet absorber, methyl ethyl ketone peroxide and cobalt isooctanoate in a ratio of 35% unsaturated polyester resin, 33% glass fiber yarn, 28% aluminum hydroxide, 1% color paste, 0.15% ultraviolet absorber, 0.85% methyl ethyl ketone peroxide and 0.28% cobalt isooctanoate; Step 2: Molding: pour the glass fiber yarn into the production mold and lay it evenly, then evenly pour the material divided into barrels in step 3 on the laid glass fiber yarn layer to ensure that the material fully infiltrates the glass fiber yarn layer to form a composite material; then apply a pressure of 0.1-0.3MPa to the composite material after pouring to discharge the bubbles therein, and heat and solidify the composite material after pressure defoaming; then cool it to 60-80°C, take it out of the mold, and obtain the grid plate 1; Step 3: Finishing: Cut, mill and drill the grid plate 1 obtained in step 2, and cover and sand the surface of the plate; then conduct a comprehensive inspection, repair and finishing to obtain the final product.
