Abstract
Description
Technical Field
[0001] This utility model relates to the field of power fittings technology, and in particular to corrosion-resistant power fittings based on graphene coating. Background Technology
[0002] In power systems, power fittings are crucial tools for reinforcing and limiting cables, and their performance directly affects the stability and safety of power transmission. Traditional power fittings can effectively reinforce and limit cables in general environments, but they face numerous challenges in special environments such as coastal areas and industrial zones.
[0003] Coastal areas have high humidity and high salt content, making power fittings highly susceptible to salt spray corrosion. Industrial areas, due to emissions from industrial production activities, contain various corrosive gases and pollutants, further exacerbating the corrosion of power fittings. In this highly corrosive environment, the protective layer on the surface of traditional power fittings is easily damaged, exposing the metal substrate directly to the corrosive medium, leading to corrosion. Corrosion not only reduces the mechanical strength of power fittings, potentially causing breakage and loosening during long-term use, affecting cable fixation and even potentially triggering power accidents; it also degrades conductivity, increasing resistance during power transmission, resulting in increased energy loss and reduced power transmission efficiency.
[0004] Furthermore, traditional power fittings often have low structural strength and are easily damaged by external impacts. For example, under the influence of natural disasters (such as strong winds and hail) or human factors (such as construction collisions), power fittings may deform or crack, thus failing to perform their function of reinforcing and limiting cables, posing a threat to the safe operation of the power system. To address these issues, we propose corrosion-resistant power fittings based on graphene coatings. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant power fitting based on a graphene coating.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The corrosion-resistant power fitting based on graphene coating includes two support frames, which are spliced together. The upper end of each support frame is hinged with a cover plate. Both the cover plate and one end of the support frame are fixed with a reinforcing structure. The support frame and the reinforcing structure are connected by two U-shaped mounting rods. A padding layer is provided inside the support frame. The support frame is composed of a substrate pretreatment layer, a conductive transition layer and a gradient functional layer.
[0008] Preferably, the reinforcing structure includes an upper reinforcing plate fixed to the upper end of the cover plate, a lower reinforcing plate fixed to the lower end of the bearing frame, and a graphene clay layer coated on the upper reinforcing plate, the lower reinforcing plate, and the perimeter sidewalls of the bearing frame.
[0009] Preferably, both the upper and lower reinforcing plates have a double dovetail structure.
[0010] Preferably, two U-shaped mounting rods pass through both sides of the upper reinforcing plate, the lower reinforcing plate, and the bearing frame and extend to the lower end of the lower reinforcing plate. The U-shaped mounting rods are provided with external threads, and four nuts are screwed onto the external threads. Two nuts on the same side abut against the lower end of the lower reinforcing plate, and two nuts on the other side abut against the upper end of the upper reinforcing plate.
[0011] Preferably, the support frame has two slots on one side and two plugs corresponding to the slots on the other side, with one plug on the same side being inserted into one slot on the same side.
[0012] Preferably, the padding layer has three mounting grooves at equal intervals.
[0013] In this utility model, during installation:
[0014] 1. Preliminary preparations
[0015] Prepare all the necessary components and check that each component is intact, especially the substrate pretreatment layer, conductive transition layer and gradient functional layer of the support frame, and whether the graphene coating on the upper and lower reinforcing plates is uniform and complete.
[0016] 2. Cable installation
[0017] Open the hinged cover at the top of the support frame and place the cable that needs to be reinforced and limited in the mounting groove on the pad. There are three mounting grooves at equal intervals. You can choose the placement position reasonably according to the number and layout of the cable to ensure that the cable is placed stably in the mounting groove and avoid shaking or displacement.
[0018] 3. Installation of the closed cover and reinforcing structure
[0019] Close the cover plate to ensure it fits tightly against the support frame. At this point, the upper reinforcing plate on the cover plate corresponds to the lower reinforcing plate at the bottom of the support frame. Insert two U-shaped mounting rods through the upper and lower reinforcing plates and the support frame on both sides. The external threads on the U-shaped mounting rods extend to the lower end of the lower reinforcing plate after passing through the corresponding holes. Screw nuts onto the external threads of the U-shaped mounting rods. Tighten the two nuts on the same side to the lower end of the lower reinforcing plate, and tighten the two nuts on the other side to the upper end of the upper reinforcing plate. Through the tightening action of the nuts, the upper and lower reinforcing plates and the support frame are tightly connected together, completing the installation of the reinforcing structure.
[0020] 4. Modular splicing
[0021] If multiple sets of electrical fittings need to be installed and spliced, the plugs on one side of the support frame and the slots on the other side can be used for splicing. Insert the plug of one support frame into the slot of the adjacent support frame to ensure a tight and secure splice.
[0022] This utility model has the following advantages:
[0023] 1. The load-bearing frame is composed of a substrate pretreatment layer, a conductive transition layer, and a gradient functional layer. The multi-layer structure design can effectively improve the overall performance of the load-bearing frame. At the same time, the upper reinforcing plate, the lower reinforcing plate, and the side walls of the load-bearing frame are all coated with graphene coating. Graphene has excellent chemical stability and barrier properties, which can effectively prevent corrosive media such as salt spray and corrosive gases from contacting the metal substrate, thereby greatly improving the corrosion resistance of power fittings and extending their service life in highly corrosive environments.
[0024] 2. Both the upper and lower reinforcing plates have a double dovetail structure. The unique structural design can increase the stress area and structural stability of the reinforcing plates, effectively disperse external forces, and improve the overall mechanical strength of the power fittings. When subjected to impact or other external forces, the double dovetail structure of the reinforcing plates can better resist deformation and damage, ensuring the reinforcing and limiting function of the power fittings on the cables.
[0025] 3. This power fitting can be modularly installed and spliced in multiple groups according to actual needs. Through the cooperation of plugs and slots, multiple load-bearing frames can be connected together conveniently and quickly to form cable reinforcement and limiting systems of different sizes and layouts. The modular design not only facilitates installation and disassembly, but also allows for flexible adjustment according to the number, direction and distribution of cables to meet the diverse needs of different power projects.
[0026] In summary, the power fittings of this utility model have good corrosion resistance and mechanical strength, which can effectively reduce the problems of decreased mechanical strength and deterioration of conductivity caused by rust and damage. They help maintain the stable fixation and good conductivity of cables, reduce resistance and power loss during power transmission, improve the efficiency and stability of power transmission, and provide a strong guarantee for the safe and reliable operation of the power system.

Detailed Implementation
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0036] Reference Figure 1-7 The corrosion-resistant power fitting based on graphene coating includes two support frames 8, with two adjacent support frames 8 spliced together. The upper end of the support frame 8 is hinged with a cover plate 7. The hinged design facilitates the opening and closing of the cover plate 7, making it convenient for cable installation and maintenance.
[0037] Both the cover plate 7 and the bearing frame 8 are fixed with a reinforcing structure at one end. The bearing frame 8 and the reinforcing mechanism are connected by two U-shaped mounting rods 4. The bearing frame 8 is provided with a pad 10. The bearing frame 8 is composed of a substrate pretreatment layer 11, a conductive transition layer 12 and a gradient functional layer 13. The substrate pretreatment layer 11 can improve the surface quality of the bearing frame substrate and enhance the adhesion of subsequent coatings. The conductive transition layer 12 can ensure the stability of power transmission. The gradient functional layer 13 can enable the bearing frame to have good performance in different working environments. The substrate pretreatment layer 11 is made of low carbon alloy steel, the conductive transition layer 12 is made of copper-based composite material, and the gradient functional layer 13 is made of polyurethane epoxy resin system combined with conductive filler.
[0038] The reinforcing structure includes an upper reinforcing plate 3 fixed to the upper end of the cover plate 7, and a lower reinforcing plate 5 fixed to the lower end of the bearing frame 8. The upper reinforcing plate 3, the lower reinforcing plate 5, and the side walls of the bearing frame 8 are all coated with graphene. Graphene has excellent corrosion resistance. Coating these parts can effectively improve the corrosion resistance of power fittings and extend their service life.
[0039] Both the upper reinforcing plate 3 and the lower reinforcing plate 5 have a double dovetail structure. The double dovetail structure not only increases the strength of the reinforcing plate itself, but also better cooperates with the load-bearing frame 8 and the U-shaped mounting rod 4, thereby improving the stability of the entire power fitting.
[0040] Two U-shaped mounting rods 4 pass through both sides of the upper reinforcing plate 3, the lower reinforcing plate 5, and the bearing frame 8 respectively and extend to the lower end of the lower reinforcing plate 5. The U-shaped mounting rods 4 are provided with external threads 14, and four nuts 1 are screwed onto the external threads 14. Two nuts 1 on the same side abut against the lower end of the lower reinforcing plate 5, and two nuts 1 on the other side abut against the upper end of the upper reinforcing plate 3. The U-shaped mounting rods 4 use the tightening action of the nuts to make the upper reinforcing plate 3, the lower reinforcing plate 5, and the bearing frame 8 tightly connected together to form a stable whole.
[0041] Two slots 6 are provided on one side of the support frame 8, and two plugs 2 corresponding to the slots 6 are provided on the other side of the support frame 8. One plug 2 on the same side is inserted into one slot 6 on the same side. The design of the slots and plugs facilitates the splicing of multiple electrical fittings and can be flexibly combined according to actual needs to achieve modular installation.
[0042] The padding layer 10 is provided with three mounting slots 9 at equal intervals. The design of the mounting slots 9 can reasonably select the placement position according to the number and layout of the cables, ensuring that the cables are placed stably in the mounting slots 9, avoiding shaking or displacement, thereby ensuring the safe operation of the cables.
[0043] In this utility model, during installation:
[0044] 1. Preliminary preparations
[0045] Prepare all the necessary components and check whether each component is intact, especially whether there is any damage to the substrate pretreatment layer 11, conductive transition layer 12 and gradient functional layer 13 of the support frame 8, and whether the graphene coating on the upper reinforcing plate 3 and the lower reinforcing plate 5 is uniform and complete.
[0046] 2. Cable installation
[0047] Open the cover plate 7 hinged at the upper end of the support frame 8, and place the cable that needs to be reinforced and limited in the mounting groove 9 on the pad 10. There are three mounting grooves 9 at equal intervals. The placement position can be reasonably selected according to the number and layout of the cable to ensure that the cable is placed stably in the mounting groove 9 and to avoid shaking or displacement.
[0048] 3. Installation of the closed cover and reinforcing structure
[0049] Close the cover plate 7 so that the cover plate 7 fits tightly against the support frame 8. At this time, the upper reinforcing plate 3 on the cover plate 7 corresponds to the lower reinforcing plate 5 at the lower end of the support frame 8. Insert two U-shaped mounting rods 4 through the upper reinforcing plate 3, the lower reinforcing plate 5 and the two sides of the support frame 8 respectively. The external thread 14 on the U-shaped mounting rod 4 passes through the corresponding hole and extends to the lower end of the lower reinforcing plate 5. Screw nuts 1 onto the external thread 14 of the U-shaped mounting rod 4. Tighten the two nuts 1 on the same side to the lower end of the lower reinforcing plate 5, and tighten the two nuts 1 on the other side to the upper end of the upper reinforcing plate 3. Through the tightening action of the nuts 1, the upper reinforcing plate 3, the lower reinforcing plate 5 and the support frame 8 are tightly connected together, and the installation of the reinforcing structure is completed.
[0050] 4. Modular splicing
[0051] If multiple sets of electrical fittings need to be installed and spliced, the plug 2 on one side of the support frame 8 and the slot 6 on the other side can be used for splicing. Insert the plug 2 of one support frame 8 into the slot 6 of the adjacent support frame 8 to ensure a tight and firm splice.
