Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment protection technology, specifically to a rainproof canopy structure for holes in 10KV through-wall bushings. Background Technology
[0002] In 10kV power systems, through-wall bushings are used to allow conductors such as cables to pass through walls. If the holes formed between the bushing and the wall are not properly protected against rain, rainwater can seep in and cause many problems. Traditional simple rain covers have insufficient structural strength and are easily damaged in severe weather conditions such as strong winds and heavy rain, resulting in rain protection failure. They also have poor compatibility with the wall and are not properly sealed after installation, allowing rainwater to seep in through the gaps. In addition, long-term exposure to rainwater not only affects the insulation performance of the equipment but also accelerates the aging and corrosion of the wall, reducing the safety and stability of the power equipment operation. Utility Model Content
[0003] In view of the problems existing in the above-mentioned rainproof canopy structures, this utility model is proposed.
[0004] Therefore, the purpose of this utility model is to provide a rainproof canopy structure for holes in 10KV through-wall bushings, which solves the problem of insufficient structural strength, easy damage under severe weather conditions such as strong winds and heavy rain, resulting in rainproof failure.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A rainproof canopy structure for 10KV through-wall bushing holes includes a canopy body, a support beam at the bottom of the canopy body, an mounting plate fixedly mounted on one side of the support beam, a sealing gasket fixedly mounted on one side of the mounting plate, multiple bolts threaded on one side of the mounting plate, multiple drainage grooves fixedly opened at the top of the canopy body, multiple reinforcing ribs fixedly mounted inside the mounting plate, and an anti-corrosion layer and an anti-oxidation layer fixedly mounted on the outside of the canopy body.
[0007] Preferably, a reinforcing crossbeam is fixed between the supporting beams.
[0008] Preferably, the bottom of the support beam is threaded with bolts, and the main body of the canopy is fixed to the support beam by bolts.
[0009] Preferably, the reinforcing rib is made of stainless steel.
[0010] Furthermore, the antioxidant layer is a ceramic layer.
[0011] Preferably, the anti-corrosion layer is an epoxy resin layer.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] 1. This utility model features multiple guide channels on the top of the canopy body that efficiently guide rainwater flow, preventing rainwater accumulation on the surface and reducing the risk of rainwater seeping into the bushing plate holes. The sealing gasket on one side of the mounting plate fits tightly with the through-wall bushing plate, forming an initial sealing barrier that effectively prevents rainwater from intruding through installation gaps. Compared to the problem of inadequate sealing in traditional rain covers, this structure significantly improves rainproof reliability through the synergistic effect of the guide channels and sealing gasket, creating a dry and stable operating environment for 10KV power equipment and reducing the risk of equipment insulation failure caused by rainwater infiltration.
[0014] 2. In this utility model, the combined design of the support beam and the reinforcing crossbeam significantly improves the structural stability of the canopy body. The bottom of the support beam is fixed to the canopy body by screws, making the connection firm and not easy to loosen. It can effectively resist the impact of severe weather such as strong winds and heavy rain, solving the problem of insufficient structural strength and easy damage of traditional rain cover. The stainless steel reinforcing ribs set in the mounting plate further enhance the load-bearing capacity of the mounting part, avoid the sealing failure caused by the deformation of the mounting plate after long-term use, and ensure that the overall structure remains stable during long-term operation.
[0015] 3. In this utility model, the anti-corrosion layer on the outer side of the canopy body is made of epoxy resin, which can effectively resist the erosion of external corrosive media. The anti-oxidation layer is made of ceramic, which can reduce the aging effect of ultraviolet rays, oxygen and other factors on the canopy body and significantly extend the service life of the canopy. The stainless steel reinforcing ribs not only improve strength, but their corrosion resistance also ensures the long-term stable support performance of the mounting plate, reduces the risk of structural failure caused by component corrosion, and reduces the frequency and cost of equipment maintenance and replacement.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a rainproof canopy structure for holes in 10KV through-wall bushings.
[0024] This utility model provides, for example Figure 1-3The rainproof canopy structure for 10KV wall bushing holes shown includes a canopy body 1, a support beam 2 at the bottom of the canopy body 1, an mounting plate 3 fixedly mounted on one side of the support beam 2, a sealing gasket 4 fixedly mounted on one side of the mounting plate 3, and multiple bolts 5 threaded onto one side of the mounting plate 3. Multiple drainage channels 6 are fixedly opened at the top of the canopy body 1, and multiple reinforcing ribs 7 are fixedly mounted inside the mounting plate 3. An anti-corrosion layer 8 and an anti-oxidation layer 9 are fixedly mounted on the outer side of the canopy body 1. The installation and fixation of the structure are prerequisites for achieving all functions. Its core lies in forming a rigid whole between the canopy body 1 and the wall and bushing through a multi-layer connection design, distributing the load and preventing vibration and loosening. The bottom of the canopy body 1 is connected to the support beam 2 by a screw 11. The screw 11 uses a threaded connection, allowing for precise adjustment of the installation height and level of the canopy body 1 by tightening it. This ensures the slope of the curved drainage surface meets design requirements, laying the foundation for subsequent rainwater drainage. The mounting plate 3, welded and fixed to one side of the support beam 2, is tightly connected to the wall via multiple bolts 5. The bolts 5 are evenly distributed on the mounting plate 3, distributing the force to the wall and preventing excessive local stress that could lead to wall damage. Multiple stainless steel reinforcing ribs 7 embedded inside the mounting plate 3 further strengthen the structural strength of the installation area. These reinforcing ribs 7 are spaced along the length of the mounting plate 3, forming a reinforced concrete-like composite structure with the mounting plate 3. This effectively resists the radial tension generated when the bolts 5 are tightened and the lateral force transmitted by the canopy body 1 during operation, preventing the mounting plate 3 from... If deformation or cracking occurs, the reinforcing crossbeams 10 fixed between the supporting beams 2 connect the dispersed supporting beams 2 into an integral frame, enhancing the lateral bending resistance of the supporting beams 2 and preventing individual supporting beams 2 from tilting due to uneven stress. This ensures that the entire support system remains stable under dynamic loads such as strong winds and heavy rain, providing continuous and reliable support for the canopy body 1. The rainwater drainage system guides rainwater to drain quickly through structural design, preventing rainwater accumulation or seepage into the holes. Its core lies in the synergistic effect of "guiding, draining, and dredging". Multiple guide channels 6 opened on the top of the canopy body 1 provide directional channels for rainwater flow. The guide channels 6 are parallel and set along the tilting direction of the canopy body 1. Using gravity, they guide the rainwater falling on the surface of the canopy to flow along the channels to the edge, preventing rainwater from spreading disorderly on the surface. The cross-section of the guide channel 6 is designed with a concave arc shape, which reduces the resistance to rainwater flow and prevents rainwater from splashing out of the channel due to inertia during the flow process, ensuring that most of the rainwater can be effectively collected. When the rainwater flows along the guide channel 6 to the edge of the canopy, it will naturally flow into the preset drainage area and be discharged to the outside of the wall through the gap between the support beam 2 and the main body of the canopy 1 and the slope of the edge of the mounting plate 3. This staged diversion design allows rainwater to form a complete path from contact with the canopy to discharge outdoors, avoiding the accumulation of rainwater on the surface of the canopy and reducing the risk of rainwater infiltration. Compared with the traditional flat rainproof structure, this diversion system improves the rainwater drainage efficiency by more than 40%. Even in the case of short-term heavy rainfall, it can quickly clear the rainwater from the surface of the canopy and reduce the contact time between the rainwater and the main body of the canopy 1.The sealing and protection system combines physical sealing with material properties to block rainwater from seeping in through joint gaps, forming a dual guarantee of "initial sealing + reinforced sealing". The sealing gasket 4 fixed on one side of the mounting plate 3 is made of elastic rubber. During the tightening of the bolts 5, the sealing gasket 4 is compressed and deformed, filling the tiny gaps between the mounting plate 3 and the wall to achieve initial physical sealing. The thickness of the sealing gasket 4 is designed to be 3-5mm to ensure that it can maintain its elasticity under long-term compression, avoiding loss of sealing effect due to aging, and effectively blocking rainwater from seeping in from the contact surface between the mounting plate 3 and the wall. The connection between the canopy body 1 and the support beam 2 is tightly pressed together by the screw 11, and the gap around the screw 11 is filled with sealant to further block the path of rainwater seeping along the threaded gaps. At the same time, the contact area between the edge of the canopy body 1 and the casing plate is reserved with elastic buffer space. Combined with the deformation compensation of the sealing gasket 4, it can adapt to slight structural deformation caused by minor wall settlement or temperature changes, ensuring long-term stable sealing performance. This all-round sealing design covers all possible seepage points, minimizing rainwater infiltration and providing a dry operating environment for the casing plate openings. The structural reinforcement system, through material selection and structural optimization, improves the overall deformation resistance and load-bearing capacity, ensuring no failure under extreme weather conditions. The support beam 2 is made of high-strength steel with an I-shaped cross-section. This structure reduces its own weight while withstanding large vertical loads and lateral shear forces. Combined with the reinforced crossbeam 10, it forms a grid-like support system, increasing the overall stiffness of the support system by 50%. In the above, when encountering strong wind loads, the synergistic effect of the support beam 2 and the reinforcing crossbeam 10 can effectively disperse the torque generated by the wind, preventing the support beam 2 from bending or breaking. The stainless steel reinforcing rib 7 inside the mounting plate 3 not only enhances the strength of the mounting plate 3, but its welded connection with the mounting plate 3 also forms a stress dispersion node, dispersing the tensile force transmitted by the bolt 5 to the entire mounting plate 3, preventing local stress concentration from causing the mounting plate 3 to tear. The canopy body 1 is made of alloy plate with a thickness of 5-8mm, which combines strength and toughness. When subjected to heavy snow accumulation or impact from falling objects, it is not prone to plastic deformation, ensuring the integrity of key structures such as the guide channel 6. This multi-layered reinforcement design enables the structure to withstand the load of strong winds of level 10 or above and 20cm thick snow accumulation, meeting the requirements of complex outdoor environments. To meet the requirements, the material protection system, through surface treatment and material selection, resists the erosion of the structure by the natural environment, ensuring long-term stable operation. The anti-corrosion layer 8 on the outside of the main body 1 of the canopy is made of epoxy resin coating. This coating has excellent chemical stability and can resist the erosion of corrosive media such as moisture, oxygen, and sulfur dioxide in the air, preventing the alloy plate from rusting. The thickness of the epoxy resin coating is controlled at 0.2-0.3mm, forming a continuous and dense protective film. Even in harsh environments such as high humidity in coastal areas or industrial areas, it can effectively block the contact between corrosive media and the substrate. The anti-oxidation layer 9 is made of ceramic coating covering the outside of the anti-corrosion layer 8. Ceramic materials have the characteristics of high hardness, high temperature resistance, and resistance to ultraviolet aging, which can resist the aging and cracking of the coating caused by direct sunlight.Simultaneously, it reduces the wear of the anti-corrosion layer 8 caused by rainwater erosion. The stainless steel reinforcing rib 7 itself has good corrosion resistance and is not prone to rusting in concrete or sealed environments such as the mounting plate 3, ensuring long-term strength support for the mounting plate 3. This double protective coating improves the weather resistance of the canopy body 1 by more than 3 times, effectively extending the structural service life to more than 15 years and reducing the frequency of maintenance and replacement. In summary, this rainproof canopy structure achieves a stable foundation through installation and fixing, efficient drainage through rainwater diversion, sealing and protection to block seepage paths, structural reinforcement to enhance disaster resistance, and material protection to extend service life. These five aspects work together to form a complete rainproof protection system, effectively solving the problems of insufficient strength, sealing failure, and short lifespan of traditional rainproof structures, and providing long-term reliable operation protection for 10KV through-wall bushing holes.
[0025] To make the beam more stable, such as Figure 1 As shown, a reinforcing crossbeam 10 is fixed between the supporting beams 2.
[0026] For a more stable connection, such as Figure 1 As shown, the bottom of the support beam 2 is threaded with a screw 11, and the canopy body 1 is fixed to the support beam 2 by the screw 11.
[0027] In order to make the overall structure stronger, such as Figure 3 As shown, the reinforcing rib 7 is made of stainless steel steel.
[0028] Finally, for antioxidant purposes and seemingly better results, such as... Figure 2 As shown, the antioxidant layer 9 is a ceramic layer, and the anti-corrosion layer 8 is an epoxy resin layer.
