Description

Technical Field

[0001] This utility model relates to the field of antimagnetic structure design, and in particular to an antimagnetic structure for a wall-mounted D-type carbon steel support component. Background Technology

[0002] Magnetization Risks of Wall-Mounted Support Components: Traditional wall-mounted D-type carbon steel support components (such as generator wind tunnel maintenance platform supports) use an all-carbon steel welded structure. A closed magnetic circuit easily forms at the intersection of the arc and straight sections of the D-shaped cross-section. In a strong magnetic field environment, carbon steel, due to its high magnetic permeability, is prone to the following problems:

[0003] 1. Eddy current loss: Induced eddy currents are generated in the alternating magnetic field, which leads to local temperature rise in the component and accelerates material fatigue;

[0004] 2. Residual magnetism accumulation: Permanent magnets are formed in a DC magnetic field, which attract ferromagnetic dust and affect the operating accuracy of the equipment;

[0005] 3. Magnetic circuit coupling: The wall-mounted fixing bolts (made of carbon steel) and the supporting column form a magnetic conductive path, expanding the magnetization area.

[0006] Traditional demagnetization methods have some limitations, making them unsuitable for direct application.

[0007] 1. Single material replacement: All-aluminum alloy materials are insufficient in supporting the structural strength of heavy loads and cannot meet the requirements of heavy loads;

[0008] 2. Post-installation demagnetization: The AC demagnetization method requires offline operation and cannot solve the problem of continuous magnetization in the dynamic magnetic field after installation at the work site;

[0009] Structural design deficiencies: The magnetic circuit distribution of the D-shaped cross-section was not optimized, resulting in limited antimagnetic effect. Utility Model Content

[0010] The purpose of this utility model is to provide a wall-mounted D-type carbon steel support assembly anti-magnetization structure to address the above-mentioned shortcomings, thereby solving the problems of traditional anti-magnetization methods mentioned in the background art.

[0015] Based on the above-mentioned antimagnetic structure of a wall-mounted D-type carbon steel support assembly, a reinforcing plate is provided on the end face of the support vertical plate away from the first anti-eddy current hole, and the reinforcing plate is connected to the support vertical plate and the fixed base plate respectively; multiple reinforcing plates are provided along the length direction of the support vertical plate.

[0016] Based on the above-mentioned antimagnetic structure of a wall-mounted D-type carbon steel support assembly, the non-magnetic stainless steel gasket is disposed on the side of the support vertical plate near the first anti-eddy current hole.

[0017] Based on the above-mentioned antimagnetic structure of a wall-mounted D-type carbon steel support component, the cantilever support includes a first side plate, a second side plate, a connecting plate, and a supporting top plate; the first side plate and the second side plate are arranged in parallel, the connecting plate is located between the first side plate and the second side plate, and the supporting top plate is located at the top of the first side plate and the second side plate, with the first side plate and the second side plate within the coverage area of ​​the supporting top plate.

[0018] Based on the above-mentioned antimagnetic structure of a wall-mounted D-type carbon steel support component, the first side plate and the second side plate have the same structure, both being C-type structures.

[0019] Based on the above-mentioned anti-magnetic structure of a wall-mounted D-type carbon steel support assembly, the connecting plate includes a first bottom plate, a second bottom plate, a first vertical plate, a second vertical plate, a first top plate, and a sub-plate; the first bottom plate and the second bottom plate are arranged parallel to each other at the bottom position between the first side plate and the second side plate, and the first vertical plate and the second vertical plate are arranged at the side position between the first side plate and the second side plate; the first top plate is located at the top position between the first side plate and the second side plate, and the first top plate is arranged parallel to the supporting top plate; the sub-plate is located at the position between the first side plate and the second side plate behind the first top plate, and the sub-plate is arranged perpendicular to the first top plate.

[0020] Based on the above-mentioned antimagnetic structure of a wall-mounted D-type carbon steel support component, a second anti-eddy current hole is provided on the first bottom plate, the second bottom plate, the first vertical plate, the second vertical plate, the first top plate, the auxiliary plate, and the support top plate.

[0025] 3. A support structure combining stiffeners and main components is adopted, forming a three-dimensional steel structure with convex and concave surfaces through the arrangement of the stiffeners. This structure enhances the load-bearing capacity of the components on the one hand, and scatters the incident magnetic flux by changing the distribution characteristics of the magnetic field on the surface of the components, reducing the local magnetic flux density and the possibility of magnetic eddy current formation, thereby achieving simultaneous optimization of load-bearing performance and anti-magnetic effect.

[0026] 4. Grounding terminals are installed at specific locations on the supporting components, forming a single-point grounding loop with the grounding device through conductive connecting parts. The grounding system is isolated from the steel components using insulating materials to ensure that only static electricity and residual magnetic induced charges are discharged, avoiding the introduction of additional magnetic paths.

[0035] Example 1

[0036] like Figures 1-3 As shown, this utility model provides a technical solution:

[0037] A wall-mounted D-type carbon steel support assembly with anti-magnetization structure includes a fixed base 1 and a cantilever support 2; the cantilever support 2 is connected to the fixed base 1 by bolts 3, and the cantilever support 2 is provided with a cavity structure 4 to avoid external pipelines; a non-magnetic stainless steel gasket 5 is provided at the connection between the cantilever support 2 and the fixed base 1; and anti-eddy current holes are provided on both the cantilever support 2 and the fixed base 1.

[0038] Based on the above structure, this solution can cut off the magnetic conduction path between the fixed base 1 and the cantilever support 2 by installing a non-magnetic stainless steel gasket 5 at the connection between the cantilever support 2 and the fixed base 1, thus avoiding the formation of a closed magnetic circuit and cutting off the magnetic field coupling channel at the connection node. The setting of the eddy current elimination hole in this solution can form a disturbance structure for the magnetic field. By disrupting the eddy current path, the generation of induced eddy currents in the alternating magnetic field is suppressed, thereby reducing eddy current loss and heating effect and improving the stability of the component in the dynamic magnetic field.

[0039] As an example, the fixed base 1 may include a fixed base plate 11 and a supporting vertical plate 12; the supporting vertical plate 12 is symmetrically arranged along the center position of the fixed base plate 11 and is perpendicular to the fixed base plate 11; a first fixing hole 13 for connecting to the wall is also provided on the fixed base plate 11; a second fixing hole 14 for connecting to the cantilever support 2 is provided on the supporting vertical plate 12.

[0040] Based on the above structure, setting the fixed base plate 11 as a planar structure in this solution can increase the contact area with the wall, allowing the fixed base plate 11 to fit more closely and flatly when fixed to the wall. This increases the assembly accuracy and strengthens the connection between the base plate 11 and the wall, making it less prone to shaking during long-term use.

[0041] As an example, the fixed base plate 11 is a flat plate as a whole, and a first anti-vortex hole 15 is provided on the fixed base plate 11 between adjacent support vertical plates 12; the first anti-vortex hole 15 is provided in multiple ways along the length direction of the fixed base plate 11.

[0042] Based on the above structure, by setting the first eddy current suppression hole 15 on the fixed base plate 11, the eddy current path formed by the fixed base plate 11 itself can be disrupted, thereby suppressing the generation of induced eddy currents in the alternating magnetic field.

[0043] As an example, a reinforcing plate 16 can be provided on the end face of the supporting vertical plate 12 away from the first anti-vortex hole 15. The reinforcing plate 16 is connected to the supporting vertical plate 12 and the fixed base plate 11 respectively. Multiple reinforcing plates 16 are provided along the length direction of the supporting vertical plate 12.

[0044] Based on the above structure, the connection strength between the supporting vertical plate 12 and the fixed base plate 11 can be increased by setting the reinforcing plate 16, so as to avoid deformation of the supporting vertical plate 12. Since the supporting vertical plate 12 is directly connected to the cantilever support 2, it will be subjected to a large force. Setting the reinforcing plate 16 can increase the stability of the entire structure.

[0045] As an example, a non-magnetic stainless steel pad 5 is provided on the side of the support vertical plate 12 near the first anti-eddy current hole 15.

[0046] Based on the above structure, since the contact part between the cantilever support 2 and the support vertical plate 12 is located between the two support vertical plates 12, the non-magnetic stainless steel pad 5 is placed near the side of the support vertical plate 12 close to the first eddy current elimination hole 15, which can ensure that the magnetic field coupling channel at the connection node between the two structures is cut off.

[0047] As an example, the cantilever support 2 may include a first side plate 21, a second side plate 22, a connecting plate, and a supporting top plate 23; the first side plate 21 and the second side plate 22 are arranged in parallel, the connecting plate is located between the first side plate 21 and the second side plate 22, and the supporting top plate 23 is located at the top of the first side plate 21 and the second side plate 22, and the first side plate 21 and the second side plate 22 are within the coverage area of ​​the supporting top plate 23.

[0048] The first side plate 21 and the second side plate 22 have the same structure, both being C-shaped structures.

[0049] Based on the above structure, this solution forms a stable frame structure through the first side plate 21, the second side plate 22, and the connecting plate. At the same time, setting the first side plate 21 and the second side plate 22 as a C-shaped structure can form a cavity structure 4 that avoids the external appearance, so that the entire structure can adapt to the on-site environment. Since the supporting top plate 23 is connected to and supports the outside world, the area of ​​the supporting top plate 23 needs to be set large enough so that the first side plate 21 and the second side plate 22 can support the supporting top plate 23 within their coverage area.

[0050] As an example, the connecting plate may include a first bottom plate 24, a second bottom plate 25, a first vertical plate 26, a second vertical plate 27, a first top plate 28, and a sub-plate 29; the first bottom plate 24 and the second bottom plate 25 are arranged parallel to each other at the bottom position between the first side plate 21 and the second side plate 22, and the first vertical plate 26 and the second vertical plate 27 are arranged at the side position between the first side plate 21 and the second side plate 22; the first top plate 28 is located at the top position between the first side plate 21 and the second side plate 22, and the first top plate 28 is arranged parallel to the supporting top plate 23; the sub-plate 29 is located at the position between the first side plate 21 and the second side plate 22 behind the first top plate 28, and the sub-plate 29 is arranged perpendicular to the first top plate 28.

[0051] Second anti-vortex holes 210 are provided on the first base plate 24, the second base plate 25, the first vertical plate 26, the second vertical plate 27, the first top plate 28, the auxiliary plate 29, and the supporting top plate 23.

[0052] Based on the above structure, the first side plate 21 and the second side plate 22 are connected by the first bottom plate 24, the second bottom plate 25, the first vertical plate 26, the second vertical plate 27, the first top plate 28 and the sub-plate 29 to form a double-layer structure. The double-layer structure in this solution can reduce the use of materials on the one hand, and on the other hand, it can better suppress the generation of eddies by setting anti-eddy holes on multiple side plates and bottom plates.

[0053] As an example, the U-shaped frame structure formed by the first side plate 21 and the second side plate 22 has a first connecting end 6 at its upper end and a second connecting end 7 at its lower end; the supporting top plate 23 is at a predetermined distance from the end face of the first connecting end 6.

[0054] The widths of the first connecting end 6 and the second connecting end 7 are set to match the spacing between the two supporting vertical plates 12, and the depth to which the first connecting end 6 and the second connecting end 7 are embedded in the supporting vertical plate 12 is matched to the width of the supporting vertical plate 12.

[0055] Based on the above structure, by setting a predetermined distance between the support top plate 23 and the end face of the first connecting end 6, the first connecting end 6 and the second connecting end 7 can be better embedded between the two support vertical plates 12. At the same time, by specially setting the width and insertion depth of the first connecting end 6 and the second connecting end 7, the entire structure can be made more compact, and the assembly difficulty in the later stage can also be reduced.

[0056] As an example, a grounding terminal (not shown) can be installed at the connection between the fixed base plate 11 and the wall, forming a single-point grounding loop with the grounding device through a conductive connection component. The grounding system is isolated from the steel structure by insulating material to ensure that only static electricity and residual magnetic induced charge are discharged, avoiding the introduction of additional magnetic paths, thereby effectively reducing the static potential and residual magnetic accumulation on the surface of the structure and improving the anti-magnetic interference capability.

[0057] This solution can effectively block magnetic circuits. The non-magnetic isolation design at the connection effectively cuts off the magnetic conduction path, avoids the formation of closed magnetic circuits, significantly reduces the accumulation of residual magnetism in the magnetic field, and improves the antimagnetic stability of the component.

[0058] Meanwhile, the anti-eddy hole on the surface of the steel component in this solution works in conjunction with the convex and concave structure to disrupt the eddy current path in the alternating magnetic field, reduce eddy current loss and heat generation, avoid fatigue failure of the material due to overheating, and extend the service life of the component.

[0059] Meanwhile, the overall structural load-bearing capacity of this scheme ensures that the stiffener support structure, while achieving anti-magnetic design, enhances the load-bearing capacity of the components through a reasonable mechanical layout, ensuring its structural stiffness and stability under predetermined loads and meeting the strength requirements of engineering applications.

[0060] Meanwhile, the electrostatic and residual magnetism control single-point grounding system in this solution effectively discharges induced charges, prevents electrostatic adsorption of ferromagnetic particles and accumulation of residual magnetism, and, in conjunction with the overall structural design, keeps the components in a low magnetic state in a strong magnetic field environment, reducing interference to surrounding equipment.

[0061] Installation method:

[0062] During installation, first, holes are drilled in the wall to pre-embed high-strength chemical anchors. After completion, the platform fixing base 1 is installed on the wall and completely fixed to the wall using the platform fixing base 1 mounting nuts. Then, the cantilever support C-shaped structure is placed in the corresponding position, and a stainless steel washer is inserted between the cantilever support C-shaped structure and the platform fixing base 1 to cut off the magnetic circuit between the two structures. Finally, the two structures are securely connected together using bolts 3 fasteners.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
