Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a marine steel structure with composite material coating for isolation and corrosion protection. Background Technology

[0002] Steel structures are a major type of building structure, primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates. In steel structures, the various components are connected by welds, bolts, or rivets. Steel structures are characterized by high strength, light weight, strong adaptability, good toughness, and high reliability. Applying steel structures in construction engineering can effectively improve the performance of building projects and save construction costs. Offshore steel structures are steel structural components used in seawater.

[0003] A search revealed that CN209308064U describes a composite material-coated, corrosion-resistant marine steel structure. This structure comprises an anti-corrosion layer, a prestressed, wound composite material coating, and a surface protective layer sequentially coated on the outer side of the marine steel structure in the seawater splash zone. An annular seepage trench is formed in the seawater splash zone of the marine steel structure. This trench, after being covered by the composite material coating, forms a sealed space. One or more symmetrically arranged seawater leakage detection devices are installed within the sealed annular seepage trench. Wires are led out from one or both ends between the composite material coating and the marine steel structure. The signals from the seawater leakage detection devices are provided to indicator lights via wires and power, forming a detection loop. The composite material is prestressed and wound onto the steel structure surface to prevent seawater penetration; a double-layer anti-corrosion protection is employed; the anti-corrosion status is monitored in real time; and in the event of anti-corrosion failure, timely and accurate location and repair are carried out to avoid significant losses due to localized corrosion.

[0004] However, the above-mentioned marine steel structure still has the following problems: the marine steel structure is protected against corrosion by sacrificial anode method, but it is inconvenient to replace the metal at the anode after it is completely corroded, thus affecting the continuous protection of the steel structure. In addition, the steel structure connected by bolts is prone to the peeling off of the anti-corrosion coating, which can damage the steel structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1-2 This utility model provides a technical solution for a marine steel structure with composite material coating for isolation and corrosion protection: A marine steel structure with composite material coating for isolation and corrosion protection includes a first steel structure 1.

Positioning grooves 12 are provided on both the upper and lower sides of the sealing ring 5. Positioning blocks 6 are fixedly connected to the opposite sides of the first steel structure 1 and the second steel structure 2. The positioning blocks 6 are slidably connected inside the positioning grooves 12. By inserting the positioning blocks 6 inside the positioning grooves 12, the first steel structure 1 and the second steel structure 2 can be connected, and the sealing ring 5 can be prevented from shifting. The middle of the inner walls of the first steel structure 1 and the second steel structure 2 are fixedly connected with symmetrical upper and lower support sleeves 3. The support sleeves 3 are all equipped with a fixing component 9 that can fasten the first steel structure 1 and the second steel structure 2. The bottom of both sides of the first steel structure 1 are fixedly connected with support rings 4. The bottom of the first steel structure 1 is slidably connected with an electrode block 11. The top of the electrode block 11 is fixedly connected with a wire 10. The top of the wire 10 is fixedly connected with a threaded block 7. The electrode block 11 is used to protect the steel structure by the anodic sacrificial method to prevent the steel structure from being corroded by seawater. The support rings 4 are all fixedly connected with a support component 8 that can connect the electrode block 11.

[0020] Please see Figure 3The support assembly 8 includes a support sleeve 81, which is slidably connected to the bottom of the inner cavity of the first steel structure 1. Both sides of the support sleeve 81 are slidably connected to lead screws 84, one end of which passes through the support sleeve 81 and is connected to the inside of the support ring 4. A connecting rod 86 is fixedly connected to the middle of the bottom end of the support sleeve 81, and a connecting sleeve 87 is fixedly connected to the bottom end of the connecting rod 86. The top end of the threaded block 7 is threadedly connected to the inside of the connecting sleeve 87. Threaded sleeves 83 are fixedly connected to the inner walls of both sides of the support sleeve 81, and the lead screws 84 are threadedly connected to the threaded sleeves 83 respectively. One end of each lead screw 84 is threadedly connected to a fixed... Limiting plates 82 are fixedly connected to the opposite sides of block 85 and lead screw 84. The limiting plates 82 are slidably connected to both sides inside the support sleeve 81. By rotating the lead screw 84 and threaded sleeve 83 for threaded transmission, one end of the lead screw 84 can be driven to pass through the inside of the support ring 4. At the same time, rotating the fixing block 85 and one end of the lead screw 84 for threaded transmission can fix one end of the lead screw 84 to the support ring 4. Furthermore, by rotating the connecting sleeve 87 in the opposite direction to connect with the threaded block 7, the threaded block 7 can be separated from the inside of the connecting sleeve 87, allowing the corroded electrode block 11 to be replaced.

[0021] Please see Figure 4 The fixing component 9 includes a support cylinder 91, which is slidably connected to the top of the inner cavity of the first steel structure 1. A threaded tube 92 is slidably connected to the inner wall of the support cylinder 91. Support rods 93 are fixedly connected to both sides of the support cylinder 91 and the threaded tube 92. Support blocks 94 are fixedly connected to one end of each support rod 93. The support blocks 94 are slidably connected to the inside of the support sleeve 3. A movable seat 95 is fixedly connected to the middle of the bottom wall of the support cylinder 91. A threaded rod 96 is rotatably connected inside the movable seat 95. The top of the threaded rod 96 is threadedly connected to the inside of the threaded tube 92. Limit grooves 97 are vertically formed on both inner walls of the support cylinder 91. The bottom of both sides of the threaded tube 92 is... Each component is fixedly connected to a limiting block 98, which is slidably connected inside the limiting groove 97. An adjusting block 99 is fixedly connected to the top of the threaded rod 96. By rotating the adjusting block 99, the threaded rod 96 and the threaded tube 92 are driven to perform threaded transmission, which can drive the limiting block 98 to slide inside the limiting groove 97, preventing relative rotation between the threaded tube 92 and the support cylinder 91. As the threaded rod 96 is rotated, the threaded tube 92 moves into the support cylinder 91, causing the support block 94 to be inserted into the support sleeve 3, and causing the first steel structure 1 and the second steel structure 2 to move closer to each other, clamping and fixing the sealing ring 5 to prevent leakage.

[0022] The working principle and usage process of this utility model are as follows: The sealing ring 5 is fitted onto the top of the first steel structure 1, and the second steel structure 2 is installed on top of the sealing ring 5. Positioning blocks 6 on one side of the first steel structure 1 and the second steel structure 2 are respectively inserted into the positioning grooves 12 to fix the sealing ring 5. Then, the support cylinder 91 is inserted between the first steel structure 1 and the second steel structure 2, and the support blocks 94 on both sides are respectively inserted into the support sleeves 3. Then, rotating the adjusting block 99 drives the threaded rod 96 to rotate, causing threaded transmission between the threaded rod 96 and the threaded tube 92. This causes the threaded tube 92 to slide downwards inside the support cylinder 91, causing the support blocks 94 to be inserted into the support sleeves 3. Tightening the threaded rod 96 moves the support block 94 toward the center, clamping the sealing ring 5 and stabilizing the first steel structure 1 and the second steel structure 2. The threaded block 7 is installed inside the connecting sleeve 87. The electrode block 11 forms a galvanic cell with the steel structure in seawater. The electrode block 11 acts as the anode, generating a negative potential that flows toward the steel structure, causing the electrode block 11 to corrode. After the electrode block 11 is completely corroded, the fixing block 85 is rotated in the opposite direction, and at the same time, the screw 84 and the threaded sleeve 83 are rotated to perform threaded transmission, moving the screw 84 toward the inside of the support sleeve 81. The support sleeve 81 is then removed from the bottom of the first steel structure 1. Then, the threaded block 7 is removed from the inside of the connecting sleeve 87, allowing the electrode block 11 to be replaced.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
