Description

Technical Field

[0001] This invention belongs to the field of busbar technology, specifically a high-salinity self-cleaning salt spray resistant sealed busbar. Background Technology

[0002] Salt spray resistant sealed busbar trunking is designed for high-salinity environments such as coastal docks and offshore platforms. It features a 5052 marine-grade aluminum alloy shell, anodized and coated with a fluorocarbon self-cleaning anti-corrosion coating, capable of withstanding thousands of hours of neutral salt spray corrosion. The internal conductors use tin-plated T2 copper busbars, vacuum-cast and sealed with epoxy resin, eliminating air gaps and achieving an IP68 protection rating, completely preventing chloride ion and water vapor penetration. The joints utilize double-seal strips and a labyrinthine sealing structure, equipped with 316L stainless steel fasteners. The sloping design of the shell allows rainwater to wash away salt, reducing scale buildup. The modular assembly ensures stable heat dissipation and durable insulation performance, avoiding conductor oxidation and insulation breakdown caused by salt spray. This significantly reduces maintenance frequency in outdoor coastal environments, making it the preferred equipment for high-current mains power supply in highly corrosive environments.

[0003] Existing salt spray resistant sealed busbar trunking relies solely on the anti-corrosion coating of the shell to resist salt spray, without an automatic desalination structure. After seawater droplets evaporate, salt continues to adhere to the shell surface and flange gaps, crystallizing and accumulating, and cannot be removed autonomously. Salt crystals absorb moisture to form a conductive water film, accelerating coating corrosion and reducing insulation performance. Regular power outages and manual cleaning are required, resulting in high operation and maintenance costs. Long-term salt accumulation can easily lead to safety hazards such as flashover and joint corrosion. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a high salinity self-cleaning salt spray resistant sealed busbar trunking, which effectively solves the problems of existing salt spray resistant busbar trunking in the background art that lacks an automatic desalination structure, salt easily accumulates and corrodes the shell, requires manual cleaning, and is prone to rust and flashover hazards.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-salinity self-cleaning salt spray resistant sealed busbar trunking, comprising a busbar trunking body, brackets fixed at both ends of the lower part of the busbar trunking body, and hanging rods fixed at both ends of the top of the brackets, an equipment box assembled on the top of the busbar trunking body via two fixed rods, a track installed inside the equipment box, a movable frame slidably mounted on the track, a connecting frame mounted on the bottom of the movable frame via a support arm, and the connecting frame movably mounted on the outside of the busbar trunking body;

[0006] A servo motor is fixed to the upper part of one side of the moving frame via a fixing bracket, and a scraper is fixed to one side of the connecting frame. The scraper fits tightly against the surface of the main body of the busbar trunking. A pusher is set in front of the scraper. The output end of the servo motor is connected to a transmission component. The transmission component links the pusher and the scraper respectively. When the servo motor is running, it can drive the scraper to move as a whole through the transmission component to scrape off the salt deposits on the outer wall of the main body of the busbar trunking. At the same time, it drives the pusher to reciprocate to push away the scraped salt crystals, preventing the accumulation of salt scale.

[0007] Preferably, the transmission assembly includes an upper rotating shaft fixed to the output end of the servo motor. One end of the upper rotating shaft extends out of the moving frame and is fixed to a first gear. A second gear meshes with the first gear below. A lower rotating shaft is fixed to one side of the second gear. The end of the lower rotating shaft extends into the moving frame and is rotated and positioned with the inner wall of the moving frame. Two sets of upper drive gears and two sets of lower drive gears are fixed to the outer sides of the upper and lower rotating shafts, respectively. The upper and lower drive gears mesh with the upper and lower tooth surfaces of the track, respectively. Both ends of the upper and lower rotating shafts are rotated and limited by bearings and the moving frame. Slider blocks are provided on both sides of the track. Two sliding grooves are symmetrically fixed inside the moving frame, and the sliders are slidably assembled inside the sliding grooves. Two guide blocks are symmetrically fixed at the bottom of the moving frame. Guide grooves are opened on the inner walls of both sides of the equipment box, and the guide blocks are slidably installed in the guide grooves.

[0008] Preferably, a driving bevel gear is fixed in the middle of the lower rotating shaft, a driven bevel gear meshes with the lower part of the driving bevel gear, a shaft is fixed at the bottom of the driven bevel gear, the shaft extends downward through the support arm to the inside of the connecting frame and fixes a worm gear, the bottom end of the worm gear is rotatably positioned with the inside of the connecting frame, and the shaft body is rotatably connected to the bottom of the moving frame and the lower part of the support arm through an upper bushing and a lower bushing, respectively; a worm wheel meshes with the outer side of the worm gear, the worm wheel is coaxially fixed with a rotating rod, and the rotating rod body is rotatably assembled with the inner wall of the connecting frame through four bearing seats.

[0009] Preferably, both ends of the rotating rod are fixed with driving sprockets, and each driving sprocket is matched with a driven sprocket. A chain meshes between the driving sprocket and the driven sprocket. The outer sides of the driving sprocket and the driven sprocket are rotated and limited by the inner wall of the connecting frame. A reciprocating screw is fixed between the two driven sprockets. The reciprocating screw is threaded onto a reciprocating sleeve. The top of the reciprocating sleeve is fixedly connected to the push shovel. A sliding sleeve is fixed at the bottom of the reciprocating sleeve. A sliding rod is movably inserted inside the sliding sleeve. Both ends of the sliding rod are fixed to the inner wall of the connecting frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] (1) The present invention is equipped with an automatic cleaning mechanism that can move back and forth along the busbar. The connecting frame moves as a whole by relying on the linkage of the servo motor and the gear track. The scraper continuously adheres to the outer wall of the busbar to scrape off sea salt crystals. There is no need for manual power outages for on-site cleaning, which greatly reduces the workload and labor maintenance costs in coastal high-salt scenarios. Traditional busbars require regular power outages for manual cleaning. The coastal line has a wide range of coverage, and frequent power outages will also interfere with normal on-site production operations. This device can clean itself on a regular basis, saving a lot of manual labor and production losses.

[0012] (2) The present invention is equipped with an independent pusher shovel that pushes and scrapes away salt crystals in a reciprocating manner, which can promptly push away the salt scale accumulated on the top surface of the busbar trunking, avoid the salt crystal residue from re-attaching to the shell, reduce the continuous accumulation of salt from the source, and push the salt crystals away in a reciprocating manner to avoid the salt scale repeatedly adsorbing the shell, thereby improving the overall desalination effect.

[0013] (3) The busbar trunking body is equipped with a marine-grade aluminum alloy shell and a vacuum epoxy full-cast sealing structure, which has excellent basic salt spray protection performance. Combined with the automatic continuous desalination function, it can keep the shell surface clean for a long time, and prevent the coating corrosion, surface flashover, joint corrosion and other power supply safety hazards caused by salt crystal moisture absorption and the formation of conductive water film, thus ensuring the long-term reliable operation of the busbar trunking. Long-term accumulation of salt crystals will damage the anti-corrosion layer and increase the risk of joint overheating. This invention continuously removes accumulated salt, stabilizes insulation and conductivity performance, and is suitable for high corrosion conditions such as ports and offshore platforms.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention includes a busbar trunking body 1, which is a marine-grade aluminum alloy shell and a vacuum epoxy full-cast sealing structure, providing excellent salt spray protection performance. Supports 3 are fixed at both ends of the bottom of the busbar trunking body 1, providing basic support. Hanging rods 8 are vertically fixed on both sides of the upper end of the supports 3, allowing for overall suspension installation with external lifting components, suitable for wiring scenarios on offshore platforms and coastal factory roofs. Two fixed rods 4 are symmetrically arranged on the top surface of the busbar trunking body 1, with an equipment box 2 mounted on their upper ends. A horizontally fixed track 10 is located inside the equipment box 2, which is a toothed track structure. A sliding frame 9 is slidably fitted onto the outside of the track 10, allowing it to move horizontally along the track 10. A support arm 27 extends downwards from the bottom of the sliding frame 9, with a connecting frame 6 connected to the bottom of the support arm 27. The connecting frame 6 is a rectangular frame structure, movably fitted onto the outside of the busbar trunking body 1, and can reciprocate along the length of the busbar trunking synchronously with the sliding frame 9.

[0027] The upper outer side of the moving frame 9 is locked with the servo motor 11 by the fixing bracket 18. The inner side wall of the connecting frame 6 is fixed with the scraper 7, which is made of salt spray resistant material. The inner end face of the scraper 7 is completely in contact with the outer wall of the busbar trunking body 1. The pusher shovel 5 is arranged horizontally in front of the scraper 7. The output end of the servo motor 11 is connected to the entire transmission assembly. The transmission assembly drives the moving frame 9 to move as a whole and the pusher shovel 5 to slide back and forth. After the servo motor 11 is started, it drives the moving frame 9 to move along the track 10, so that the scraper 7 continuously scrapes away the crystallized salt on the outer wall of the busbar trunking body 1. On the other hand, it moves back and forth in conjunction with the pusher shovel 5 to push the salt crystals that have been scraped off and accumulated on the top surface of the busbar trunking to both sides, so as to avoid the salt scale from accumulating too high and remaining attached to the shell.

[0028] Depend on Figure 3 , Figure 5 and Figure 6 The transmission assembly includes an upper rotating shaft 20, which is coaxially fixed to the output end of the servo motor 11. One end of the upper rotating shaft 20 extends laterally through the side wall of the moving frame 9 and is fixed to a first gear 14. The first gear 14 meshes vertically downward with a second gear 15. A lower rotating shaft 19 is fixed to the center of the side of the second gear 15. The other end of the lower rotating shaft 19 extends into the internal cavity of the moving frame 9 and is rotated and positioned with the inner side wall of the moving frame 9. Two upper drive gears 12 are fixed to the left and right sections of the upper rotating shaft 20, and two lower drive gears 13 are fixed to the left and right sections of the lower rotating shaft 19. The two sets of upper drive gears 12 mesh with the upper teeth of the track 10, and the two sets of lower drive gears 13 mesh with the lower teeth of the track 10. The stable movement of the moving frame 9 is achieved by the meshing of the gears. Bearings 40 are installed at both ends of the upper rotating shaft 20 and the lower rotating shaft 19. The outer ring of the bearings 40 is fixed to the side wall of the moving frame 9, so as to achieve smooth rotation of the two rotating shafts and reduce transmission friction loss.

[0029] The outer walls of the track 10 are integrally formed with sliders 17 on both sides. The inside of the moving frame 9 is symmetrically provided with sliding grooves 16. The sliders 17 slide into the sliding grooves 16. The sliders 17 and the sliding grooves 16 cooperate to limit the upper and lower movement of the moving frame 9, preventing the moving frame 9 from shifting up and down or derailing during its movement.

[0030] The bottom of the moving frame 9 is symmetrically fixed with guide blocks 25. The inner walls of the left and right sides of the equipment box 2 are vertically opened with guide grooves 26. The guide blocks 25 are slidably installed inside the guide grooves 26. The guide grooves 26, together with the guide blocks 25, further constrain the movement trajectory of the moving frame 9, ensuring that the overall cleaning mechanism moves straight and does not shake.

[0031] Depend on Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a driving bevel gear 21 is fixed in the middle of the lower shaft 19. The driving bevel gear 21 meshes vertically downward with a driven bevel gear 22. The lower center of the driven bevel gear 22 is vertically fixed to a shaft 23. The shaft 23 extends vertically downward through the internal cavity of the support arm 27 to the internal cavity of the connecting frame 6. A worm gear 28 is fixed at the bottom of the shaft 23. The lower end face of the worm gear 28 is rotated and positioned against the bottom inner wall of the connecting frame 6. The shaft 23 is divided into two sections, with an upper bushing 24 and a lower bushing 39. The upper bushing 24 is fixed at the bottom opening of the moving frame 9, and the lower bushing 39 is fixed at the lower end of the support arm 27. The two bushings form a double-layer rotational support for the shaft 23, ensuring stable vertical power transmission.

[0032] The outer tooth surface of the worm 28 meshes with the worm wheel 29. The center of the worm wheel 29 is coaxially fixed with the rotating rod 30. The rotating rod 30 is horizontally arranged inside the connecting frame 6. The body of the rotating rod 30 is evenly equipped with four bearing seats 31. All four bearing seats 31 are fixed inside the connecting frame 6. The rotating rod 30 can be horizontally and stably rotated by relying on the bearing seats 31.

[0033] The left and right ends of the rotating rod 30 are respectively fixed with driving sprockets 32. Each driving sprocket 32 ​​is matched with a driven sprocket 33 directly below it. The driving sprocket 32 ​​and the driven sprocket 33 are meshed by a chain 34. The rotating shaft ends of the driving sprocket 32 ​​and the driven sprocket 33 are rotated and limited by the inner wall of the connecting frame 6. The power at both ends is transmitted synchronously by the sprocket and chain structure.

[0034] A reciprocating screw 38 is horizontally fixed between the two driven sprockets 33 on the left and right. The surface of the reciprocating screw 38 is machined with reciprocating threads. The reciprocating screw 38 is threaded to a reciprocating sleeve 37. The top surface of the reciprocating sleeve 37 is fastened to the bottom of the push shovel 5. When the reciprocating screw 38 rotates, it drives the reciprocating sleeve 37 to slide back and forth along the screw axis, which simultaneously drives the push shovel 5 to clean and push salt back and forth.

[0035] The bottom of the reciprocating threaded sleeve 37 is fixed with a sliding sleeve 35. A sliding rod 36 is horizontally inserted inside the sliding sleeve 35. The left and right ends of the sliding rod 36 are locked and fixed to the inner walls of the two sides of the connecting frame 6. The sliding sleeve 35 slides along the outer wall of the sliding rod 36. The sliding rod 36 provides radial limit for the reciprocating threaded sleeve 37, preventing the reciprocating threaded sleeve 37 from rotating synchronously with the reciprocating screw 38, and ensuring that the pushing shovel 5 only performs horizontal linear reciprocating motion.

[0036] Working principle: This equipment is equipped with an external timer control module, which can set the cycle to automatically start the cleaning process. After starting, the servo motor 11 runs and drives the upper rotating shaft 20 to rotate synchronously. The upper rotating shaft 20 drives the first gear 14 to mesh with the second gear 15 to rotate, which synchronously drives the lower rotating shaft 19 to rotate. The upper drive gear 12 and the lower drive gear 13 mesh with the toothed rail of the track 10, which drives the moving frame 9 to move at a constant speed along the track 10. The moving frame 9 drives the lower connecting frame 6 to move synchronously through the support arm 27. The scraper 7 on the inner side of the connecting frame 6 slides close to the outer wall of the busbar trunking body 1, completely scraping away the sea salt crystals and accumulated salt on the surface of the shell.

[0037] The lower rotating shaft 19 synchronously drives the active bevel gear 21 to mesh with the driven bevel gear 22, converting the horizontal power into vertical downward power, which is transmitted to the worm gear 28 via the shaft 23. The worm gear 28 meshes with the worm wheel 29 to drive the rotating rod 30 to rotate horizontally. The active sprockets 32 at both ends of the rotating rod 30 drive the driven sprockets 33 to rotate synchronously via the chain 34. The driven sprockets 33 drive the reciprocating screw 38 to rotate continuously. The reciprocating screw 38 drives the reciprocating sleeve 37 to slide back and forth along the slide rod 36. The pusher shovel 5 at the top of the reciprocating sleeve 37 moves back and forth synchronously, scraping off the salt crystals accumulated on the top surface of the busbar trunking body 1 with the scraper 7 and pushing them to both sides to fall off, thus preventing the salt scale from re-attaching to the shell.

[0038] When the moving frame 9 moves, the sliders 17 on both sides of the track 10 cooperate with the sliding grooves 16 of the moving frame 9 to limit the movement, and the bottom guide block 25 slides along the guide groove 26 of the equipment box 2. The double limit structure ensures that the cleaning mechanism moves smoothly without deviation.

[0039] This equipment is equipped with an automatic cleaning mechanism that can reciprocate outside the busbar trunking. It relies on a servo motor and gear track to achieve overall translation. The flexible scraper blades adhere to the shell to scrape off sea salt crystals, and the reciprocating push shovel in sync with the machine to clean up the fallen salt crystals, preventing salt scale from accumulating and re-attaching. The entire cleaning mechanism can run automatically at timed intervals without the need for maintenance personnel to shut down the power and operate on-site, which greatly reduces maintenance manpower and downtime losses in high-salt environments such as coastal areas and offshore platforms.

[0040] The busbar trunking itself features a marine-grade aluminum alloy shell with an epoxy-cast sealing structure, providing excellent inherent salt spray resistance. Combined with a continuous automatic desalination function, it maintains a clean shell for extended periods, preventing the formation of conductive water films from salt crystals absorbing moisture. This prevents safety issues such as shell coating corrosion, joint overheating and rust, and surface flashover. The overall structure offers stable transmission and comprehensive cleaning coverage, making it suitable for severe salt spray environments such as ports, coastal chemical plants, and offshore wind power platforms. It effectively extends the service life of the busbar trunking, improves the operational stability of high-voltage power lines, and possesses high practical value and is poised for widespread adoption.
