Description

Technical Field

[0001] This invention relates to the field of deck rust removal technology, specifically a rust removal device for ship outer decks. Background Technology

[0002] As a means of water transportation, a ship's deck is constantly exposed to the harsh marine environment, subjected to corrosion from seawater, salt spray, wind, and waves. As a result, the deck surface is prone to oxidation and rust, which not only affects the ship's appearance but, more importantly, damages its structural strength, shortens its service life, and even threatens its safe operation. Therefore, regularly performing rust removal and maintenance on the ship's outer deck is an important measure to ensure ship safety and extend its service life.

[0003] Traditional ship deck rust removal technology is limited by fixed brush head size and a single operating mode. When faced with a large area of ​​rusted deck, it is necessary to repeatedly operate back and forth in the same area to ensure that the rust is cleaned. It cannot be flexibly adjusted according to the actual rust situation, which increases the rust removal time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rust removal device for ship outer decks, solving the problem that existing brush heads cannot be flexibly adjusted according to actual needs during cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rust removal device for ship outer decks, comprising a base plate, a double-headed motor fixedly connected to the top of the base plate, a first rotating wheel fixedly mounted on the left output end of the double-headed motor, a first bevel gear fixedly mounted on the right output end of the double-headed motor, a second bevel gear rotatably connected to the top of the base plate, a rotating component fixedly connected to the bottom end of the second bevel gear, a servo motor fixedly connected to the inner diameter of the rotating component, a worm gear fixedly mounted on the output end of the servo motor, a worm wheel meshing with the left side of the worm gear, a rotating rod fixedly connected to the inner diameter of the worm wheel, a rotating disk fixedly connected to the bottom end of the rotating rod, a plurality of first sliding grooves formed on the surface of the rotating disk, a moving component slidably connected inside each of the plurality of first sliding grooves, a first cleaning brush fixedly connected to the bottom end of each of the plurality of moving components, and a collection assembly provided on the rear side of the bottom of the base plate.

[0006] Preferably, the collection assembly includes a collection hopper, which is fixedly connected to the base plate. A cleaning roller is rotatably connected between the left and right sides inside the collection hopper. A second rotating wheel is fixedly connected to the left end of the cleaning roller, and a belt is provided between the second rotating wheel and the first rotating wheel.

[0007] Preferably, a connecting bucket is fixedly connected to the top of the collecting bucket, a vacuum pump is provided on the top of the connecting bucket, the input end of the vacuum pump is fixedly connected to the connecting bucket, a storage box is fixedly provided to the output end of the vacuum pump, and the storage box is fixedly connected to the bottom plate.

[0008] Preferably, a high-pressure water pump is fixedly connected to the front top of the base plate, a water tank is fixedly installed at the input end of the high-pressure water pump, the water tank is fixedly connected to the base plate, a delivery pipe is fixedly installed at the output end of the high-pressure water pump, multiple nozzles are fixedly connected to the surface of the delivery pipe, and the delivery pipe is fixedly connected to the base plate.

[0009] Preferably, two wheels are rotatably connected to both the left and right sides of the base plate, and a push rod is fixedly connected to the rear top of the base plate.

[0010] Preferably, the bottom of the rotating component is provided with a plurality of second sliding grooves, and the plurality of moving components slide within adjacent second sliding grooves.

[0011] Preferably, a second cleaning brush is provided between each pair of adjacent first cleaning brushes, and multiple second cleaning brushes are fixedly connected to the rotating component.

[0012] Preferably, the rotating component is rotatably connected to the base plate, and the rotating rod is rotatably connected to the rotating component.

[0013] Preferably, the first bevel gear and the second bevel gear are meshed together, and the front end of the worm gear is rotatably connected to the rotating component.

[0014] Preferably, the lower surfaces of the first and second cleaning brushes are both made of hard alloy, and both the lower surfaces of the first and second cleaning brushes are provided with serrated patterns.

[0015] Working principle: The operator pushes the push rod, and moves the device to the designated position with the help of the wheels on both sides of the base plate. Then, the high-pressure water pump is started to draw water from the water tank and spray it onto the deck through the nozzles via the delivery pipe. The impact force of the high-pressure water flow loosens rust and dirt. Then, the dual-head motor is turned on to drive the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, thereby driving the rotating component to rotate. The servo motor inside the rotating component drives the worm gear to rotate, causing the worm wheel, rotating rod and rotating disk to rotate. The moving component slides in the first slide groove and the second slide groove, driving the first cleaning brush to extend or retract, and cooperates with the fixed second cleaning brush to perform outer ring, inner ring or concentrated cleaning. At the same time, the left output end of the dual-head motor drives the first rotating wheel to rotate, which in turn drives the second rotating wheel and the cleaning roller to rotate via the belt, sweeping and polishing debris. The debris is collected by the collection bucket and stored in the storage box under the action of the vacuum pump through the connecting bucket, thus completing the deck rust removal and debris cleaning.

[0016] This invention provides a rust removal device for ship outer decks. It has the following beneficial effects: 1. In this invention, a servo motor drives a worm gear to rotate. When the worm gear rotates, it drives the worm wheel, rotating rod, and rotating disk to rotate, thereby causing the moving parts to slide simultaneously in the first and second sliding grooves. This achieves the goal of extending the first cleaning brush to increase the cleaning area when the rotating parts rotate, thus improving cleaning efficiency. When the first cleaning brush retracts, the first and second cleaning brushes simultaneously clean a more concentrated area. In areas of severe rust on the outer deck of a ship, increasing the brush head density allows more brush heads to act on these areas, increasing the rust removal force per unit area and more thoroughly removing stubborn rust.

[0017] 2. In this invention, a dual-head motor drives the first and second bevel gears to rotate and clean the deck. At the same time, the dual-head motor drives the first rotating wheel to rotate, and the belt drives the second rotating wheel and the cleaning roller to rotate. At this time, the vacuum pump at the top works with the cleaning roller to collect the cleaned debris into the collection hopper. The vacuum pump sucks the debris into the storage box for collection, automatically removing debris from the deck, avoiding secondary pollution, and making the deck cleaner after rust removal and cleaning.

[0018] 3. In this invention, the deck is sprayed with high-pressure water using a high-pressure water pump, delivery pipe, and nozzle. The impact force of the high-pressure water flow loosens the rust and dirt on the deck, breaking their adhesion to the deck surface. The cleaning brush then powerfully polishes the pre-treated deck, efficiently scraping off the rust layer. Finally, the collection bucket collects the debris generated during the cleaning process, improving the cleaning efficiency of the ship's outer deck. Compared with the traditional step-by-step and fragmented cleaning method, it can complete large-area cleaning operations in a shorter time, enabling rapid follow-up operations and effectively shortening the time required for the entire cleaning process.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 This invention provides a rust removal device for ship outer decks, including a base plate 1. A dual-head motor 9 is fixedly connected to the top of the base plate 1. A first rotating wheel 10 is fixedly installed at the left output end of the dual-head motor 9, and a first bevel gear 11 is fixedly installed at the right output end of the dual-head motor 9. A second bevel gear 12 is rotatably connected to the top of the base plate 1. A rotating component 13 is fixedly connected to the bottom end of the second bevel gear 12. A servo motor 18 is fixedly connected to the inner diameter of the rotating component 13. A worm gear 19 is fixedly installed at the output end of the servo motor 18. A worm wheel 20 is meshed with the left side of the worm gear 19. A rotating rod 21 is fixedly connected to the inner diameter of the worm wheel 20. A rotating disk 22 is fixedly connected to the bottom end of the rotating rod 21. A plurality of first sliding grooves 23 are opened on the surface of the rotating disk 22. A moving component 24 is slidably connected inside each of the plurality of first sliding grooves 23. A first cleaning brush 14 is fixedly connected to the bottom end of each of the plurality of moving components 24. A collection assembly is provided on the rear side of the bottom of the base plate 1.

[0023] Specifically, the dual-head motor 9 drives the first bevel gear 11 to rotate, and the second bevel gear 12, which meshes with the first bevel gear 11, rotates accordingly, thereby driving the rotating component 13 to rotate. The servo motor 18 inside the rotating component 13 drives the worm gear 19 to rotate. At this time, the worm wheel 20, the rotating rod 21, and the rotating disk 22 rotate, causing the moving component 24 to slide in the first slide groove 23, driving the first cleaning brush 14 to extend or retract. When extended, the cleaning area is increased, making it more efficient to clean a larger area. When the first cleaning brush 14 retracts, it and the fixed second cleaning brush 15 perform more powerful grinding and rust removal on the deck.

[0024] See appendix Figure 4and attached Figure 8 The collection assembly includes a collection hopper 16, which is fixedly connected to the base plate 1. A cleaning roller 17 is rotatably connected between the left and right sides inside the collection hopper 16. A second rotating wheel 26 is fixedly connected to the left end of the cleaning roller 17. A belt 27 is provided between the second rotating wheel 26 and the first rotating wheel 10.

[0025] Specifically, the dual-head motor 9 drives the first rotating wheel 10 to rotate, which in turn drives the second rotating wheel 26 to rotate via the belt 27. This, in turn, drives the cleaning roller 17 to rotate inside the collection hopper 16. During the rust removal process on the outer deck of the ship, the cleaning roller 17 can promptly sweep away the debris polished by the first cleaning brush 14 and the second cleaning brush 15, preventing the debris from accumulating on the deck and affecting the subsequent cleaning effect. This also avoids the debris residue from re-adhering to the cleaned area, ensuring that the deck is clean and tidy after cleaning.

[0026] See appendix Figure 1 and attached Figure 8 A connecting bucket 29 is fixedly connected to the top of the collecting bucket 16. A vacuum pump 28 is installed on the top of the connecting bucket 29. The input end of the vacuum pump 28 is fixedly installed between the connecting bucket 29 and the output end of the vacuum pump 28. A storage box 8 is fixedly installed between the storage box 8 and the base plate 1.

[0027] Specifically, the collection hopper 16 is used to collect debris generated during the cleaning process. After the vacuum pump 28 is started, it generates suction to draw the debris in the collection hopper 16 into the storage box 8 through the connecting hopper 29 for storage. This prevents the debris from accumulating on the deck and causing secondary pollution, making the deck cleaner after rust removal. It also facilitates centralized processing of the collected debris.

[0028] See appendix Figure 1 and attached Figure 2 A high-pressure water pump 5 is fixedly connected to the top front side of the base plate 1. A water tank 4 is fixedly installed at the input end of the high-pressure water pump 5. The water tank 4 is fixedly connected to the base plate 1. A delivery pipe 6 is fixedly installed at the output end of the high-pressure water pump 5. Multiple nozzles 7 are fixedly connected to the surface of the delivery pipe 6. The delivery pipe 6 is fixedly connected to the base plate 1.

[0029] Specifically, the high-pressure water pump 5 draws water from the water tank 4 and delivers the water to multiple nozzles 7 through the delivery pipe 6. The nozzles 7 spray water onto the outer deck of the ship, using the impact force of the high-pressure water flow to loosen the rust and dirt on the deck, breaking their adhesion to the deck surface, preparing for subsequent grinding and rust removal by the cleaning brush, improving cleaning efficiency, and making the rust removal process more efficient and faster.

[0030] See appendix Figure 1 and attached Figure 2 The base plate 1 has two wheels 3 rotatably connected to both the left and right sides, and a push rod 2 is fixedly connected to the top rear side of the base plate 1.

[0031] Specifically, the operator pushes the push rod 2, which moves the entire unit using the wheels 3 on both sides to clean different parts of the deck.

[0032] See appendix Figure 5 and attached Figure 6 The bottom of the rotating component 13 is provided with multiple second sliding grooves 25, and multiple moving components 24 slide within adjacent second sliding grooves 25.

[0033] Specifically, the second slide groove 25 provides a sliding track for the moving part 24, allowing the moving part 24 to slide within the second slide groove 25, preventing the first cleaning brush 14 from shifting during the rotation of the rotating part 13, thereby more accurately adjusting the cleaning area and improving the rust removal effect.

[0034] See appendix Figure 6 and attached Figure 7 A second cleaning brush 15 is provided between each two adjacent first cleaning brushes 14, and multiple second cleaning brushes 15 are fixedly connected to the rotating part 13.

[0035] Specifically, while the first cleaning brush 14 extends to clean the outer ring, the second cleaning brush 15 remains fixed to clean the inner ring, expanding the area cleaned in a single pass and improving overall cleaning efficiency. When the first cleaning brush 14 retracts, both brushes simultaneously clean the inner ring, enabling concentrated deep cleaning of stubborn rust areas, enhancing cleaning power, improving rust removal effect, and allowing for flexible adjustment of the cleaning method according to the degree of rust and area size of different regions, making the cleaning work more targeted and flexible.

[0036] See appendix Figure 4 and attached Figure 5 The rotating part 13 is rotatably connected to the base plate 1, and the rotating rod 21 is rotatably connected to the rotating part 13.

[0037] Specifically, the rotating component 13 can rotate relative to the bottom plate 1 to clean the deck using the first cleaning brush 14 and the second cleaning brush 15. The rotating rod 21 is rotatably connected to the rotating component 13 so that the rotation of the rotating component 13 is not affected when the rotating rod 21 and the rotating disk 22 are rotating.

[0038] See appendix Figure 3 and attached Figure 5 The first bevel gear 11 and the second bevel gear 12 are meshed together, and the front end of the worm gear 19 is rotatably connected to the rotating part 13.

[0039] Specifically, when the first bevel gear 11 rotates, it can drive the second bevel gear 12 to rotate, thereby driving the first cleaning brush 14 and the second cleaning brush 15 at the bottom to clean. The worm gear 19 is rotatably connected to the rotating part 13 to provide support for the worm gear 19.

[0040] See appendix Figure 7 The lower surfaces of the first cleaning brush 14 and the second cleaning brush 15 are both made of hard alloy, and the lower surfaces of the first cleaning brush 14 and the second cleaning brush 15 are both provided with serrated patterns.

[0041] Specifically, the lower surfaces of the first cleaning brush 14 and the second cleaning brush 15 are made of hard alloy material, which has high hardness and strong wear resistance, effectively resisting wear during the cleaning process, extending the service life of the cleaning brush, reducing the replacement frequency, and saving costs. At the same time, the hard alloy material has strong rigidity, which can ensure that the cleaning brush maintains a stable shape when in contact with the deck and will not easily deform, ensuring the cleaning effect. The serrated pattern can increase the contact area and friction between the cleaning brush and the rust, so that the cleaning brush can more effectively scrape the rust on the deck surface when rotating, improving the rust removal efficiency. The serrated pattern can also break up the rust chips, making them easier to clean and improving the cleaning quality.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
