Description

Technical Field

[0001] This invention relates to the field of ship deck cleaning technology, specifically to an environmentally friendly cleaning and rust removal device for ship decks. Background Technology

[0002] With the development of industry, rust removal and cleaning of large ships is an important business in the shipbuilding industry and an indispensable part of shipbuilding and repair. In addition, since ships sail at sea for a long time, and there are many rainy days and high humidity at sea, rust inevitably forms on the ship deck. In order to improve the service life of ships and increase the safety of use, rust removal and cleaning must be carried out when the ship deck is corroded to a certain extent.

[0003] In existing technologies, rust removal on ship decks is generally carried out manually by spraying rust remover onto the deck with a handheld spray gun and then cleaning it with a handheld brush. However, the ship deck has a large area, which makes this rust removal method labor-intensive and costly, and it is easy to make people feel tired. Long-term exposure to this working environment can easily lead to occupational diseases among workers. Therefore, we disclose an automatic rust removal and cleaning device for ships and marine engineering to meet people's needs.

[0004] As disclosed in Chinese Patent CN216269822U, an automatic rust removal and cleaning device for ships and marine engineering involves starting a motor when the deck needs cleaning. The nozzle sprays rust remover, and a rotating rod rotates, causing a rotating gear to rotate. Under the action of the starting gear and transmission gear, the brush rotates. The rotating rod's rotation drives the starting gear, causing a cam to press against the starting baffle. Combined with the spring's reset action, this causes the starting baffle and reset baffle to reciprocate, resulting in the brush's reciprocating motion and achieving automatic rust removal from the deck. The nozzle design allows the electric cleaning vehicle to spray rust remover to remove rust from the deck, facilitating subsequent brush cleaning. Furthermore, the spray nozzle's design ensures even spraying of the rust remover, preventing rust from remaining in some areas and ensuring thorough rust removal from the entire deck, thus extending the ship's service life.

[0005] However, using rust remover alone cannot quickly and effectively remove large, thick rust deposits, thus affecting the overall rust removal efficiency of the deck.

[0006] Therefore, it is necessary to design an environmentally friendly cleaning and rust removal device for ship decks that is practical and capable of removing large areas of rust. Summary of the Invention

[0007] The purpose of this invention is to provide an environmentally friendly cleaning and rust removal device for ship decks to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an environmentally friendly cleaning and rust removal device for ship decks, comprising a cleaning cart and a push handle, wherein the push handle is fixedly connected to the left end of the cleaning cart, and a rust removal mechanism is connected inside the cleaning cart, wherein the rust removal mechanism includes a tapping unit, a cleaning unit, a spraying unit and a rinsing unit, wherein the tapping unit is located at the right end of the inside of the cleaning cart, the cleaning unit is located at the left end of the tapping unit inside the cleaning cart, the spraying unit is located at the left end of the cleaning unit inside the cleaning cart, and the rinsing unit is located at the left end of the inside of the cleaning cart.

[0009] The striking unit includes a first motor, a connecting rod, a disc, a support rod, a connector, a first round shaft, a roller, a round rod, a ring, a swing rod, a fixed rod, a rectangular tube, a sliding rod, a second round shaft, and a striking hammer. The first motor is fixedly connected to the rear right end of the cleaning cart. The connecting rod is fixedly connected to the front end of the output shaft of the first motor. The disc is fixedly connected to the front end of the connecting rod. The support rod is fixedly connected to the middle position of the right end inside the cleaning cart. The connector is fixedly connected to the left and right ends of the upper side of the support rod. The first round shaft is fixedly connected to the upper inner side of the connector. The roller is rotatably connected to the outer side of the first round shaft. The round rod is fixedly connected to the front edge of the disc. The ring is rotatably connected to the outer side of the round rod. The swing rod is fixedly connected to the lower outer side of the ring. The fixed rod is fixedly connected to the lower position of the right end inside the cleaning cart. The rectangular tube is fixedly connected to the left end of the fixed rod. The sliding rod is slidably connected to the inner side of the rectangular tube. The second round shaft is connected to the upper end of the sliding rod. The striking hammer is fixedly connected to the lower end of the sliding rod.

[0010] According to the above technical solution, a limiting groove is provided at the outer end of the roller, and the outer side of the disc is rolledly connected to the inner side of the limiting groove. This causes the first motor to start and drive the connecting rod to rotate. When the disc at the front end rotates, its edge rotates in the limiting groove of the roller, thereby limiting the rotation of the disc and providing support for the disc.

[0011] According to the above technical solution, the upper end of the fixed rod has a groove, the lower end of the swing rod has a rotating hole, the front and rear ends of the second round shaft are fixedly connected to the front and rear ends of the inner side of the groove, and the outer side of the second round shaft is rotatably connected to the inner side of the rotating hole. Thus, when the first motor is started to drive the disc to rotate clockwise, the round rod rotates clockwise along with the disc. When the round rod rotates to the highest point, it pulls the swing rod and the sliding rod to move up to the highest point, driving the hammer away from the ground.

[0012] According to the above technical solution, the cleaning unit includes a second motor, a rotating shaft, a roller, brush bristles, and a collection box. The second motor is fixedly connected to the rear side of the cleaning vehicle at the position to the left of the first motor. The rotating shaft is fixedly connected to the front end of the output shaft of the second motor. The roller is fixedly connected to the outside of the rotating shaft. The brush bristles are fixedly connected to the outside of the roller. The collection box is fixedly connected to the lower inner side of the cleaning vehicle at the position to the left of the roller.

[0013] According to the above technical solution, the end of the brush bristles away from the roller is slidably connected to the deck surface, and the lower side of the collection box is slidably connected to the deck surface. Thus, as the cleaning vehicle moves to the right, the roller driven by the second motor will sweep the rust blocks that have been knocked onto the lower deck into the collection box at the left end through the outer brush bristles.

[0014] According to the above technical solution, the spraying unit includes a first water tank, a connecting pipe, a first water storage pipe, and a spray head. The first water tank is fixedly connected to the right side of the top inner side of the cleaning vehicle. The connecting pipe is fixedly connected to the lower inner side of the first water tank. The first water storage pipe is fixedly connected to the bottom inner side of the cleaning vehicle at the left end of the receiving box. The spray head is fixedly connected to the lower end of the first water storage pipe.

[0015] According to the above technical solution, the rinsing unit includes a second water tank, a connecting pipe, a second water storage pipe, and a high-pressure nozzle. The second water tank is fixedly connected to the top left side of the inside of the cleaning vehicle. The connecting pipe is fixedly connected to the lower end of the inside of the second water tank. The second water storage pipe is fixedly connected to the bottom left side of the inside of the cleaning vehicle. The high-pressure nozzle is fixedly connected to the lower end of the second water storage pipe.

[0016] According to the above technical solution, pump bodies are provided at the bottom of the interior of both the first water tank and the second water tank. The upper end of the connecting pipe is fixedly connected to the pump body in the first water tank, and the lower end of the connecting pipe is fixedly connected to the upper end of the interior of the first water storage pipe. The first water tank contains rust remover, so that when the cleaning vehicle moves, the pump body in the first water tank is activated to draw the rust remover in the first water tank into the connecting pipe, and then into the first water storage pipe.

[0017] According to the above technical solution, the upper end of the connecting pipe is fixedly connected to the pump body inside the second water tank, and the lower end of the connecting pipe is fixedly connected to the upper end of the second water storage pipe. Thus, starting the pump body in the second water tank can draw clean water from the second water tank into the connecting pipe and then into the second water storage pipe.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the first motor is started to drive the disc to rotate clockwise, the circular rod rotates clockwise along with the disc. When the circular rod rotates to its highest point, it pulls the swing rod and the sliding rod to move upward to their highest point, causing the hammer to move away from the ground. Then, as the circular rod rotates clockwise downward, it drives the swing rod to rotate around the second circular axis. At the same time, due to gravity, the hammer falls and pulls the sliding rod downward until the circular rod reaches its lowest point. At this point, the hammer strikes the surface of the deck, knocking off large pieces of rust. Then, as the circular rod rotates upward, the swing rod rotates and pulls the sliding rod upward, lifting the hammer back away from the deck. The disc then stops rotating in preparation for the next strike, until the large pieces of rust in that area of ​​the deck are knocked off. After that, the cleaning vehicle is pushed to continue moving to other locations to remove rust.

[0019] In this invention, starting the second motor drives the rotating shaft to rotate, which in turn drives the outer roller to rotate. As the cleaning vehicle moves to the right, the roller driven by the second motor will sweep the rust blocks that have been knocked onto the lower deck into the collection box at the left end for collection and unified processing through the outer brush bristles.

[0020] This invention involves activating a pump in the first water tank during the movement of the cleaning vehicle to draw rust remover from the first water tank into a connecting pipe, which then flows into the first water storage pipe. The rust remover is then sprayed onto the deck through a spray nozzle at the lower end.

[0021] This invention allows for the extraction of clean water from the second water tank into a connecting pipe by activating the pump in the second water tank. The water then flows into the second water storage pipe and is sprayed onto the deck by a high-pressure nozzle, thus rinsing away the rust remover that has been used to remove rust from the deck.

[0033] The striking unit includes a first motor 301, a connecting rod 302, a disc 303, a support rod 304, a connector 305, a first round shaft 306, a roller 307, a round rod 308, a ring 309, a swing rod 310, a fixed rod 311, a rectangular tube 312, a sliding rod 313, a second round shaft 314, and a striking hammer 315. The first motor 301 is fixedly connected to the rear right end of the cleaning vehicle 1, and the connecting rod 302 is fixedly connected to the input of the first motor 301. At the front end of the output shaft, a disc 303 is fixedly connected to the front end of a connecting rod 302. A support rod 304 is fixedly connected to the middle right end of the cleaning vehicle 1. A connector 305 is fixedly connected to the upper left and right ends of the support rod 304. A first round shaft 306 is fixedly connected to the upper inner side of the connector 305. A roller 307 is rotatably connected to the outer side of the first round shaft 306. A limiting groove is provided at the outer end of the roller 307. The outer side of the disc 303 is in rolling connection with the inner side of the limiting groove. Thus, the first motor 301 is started to drive the connecting rod 302 to rotate. When the disc 303 at the front end rotates, its edge rotates within the limiting groove of the roller 307, thereby limiting the rotation of the disc 303 and providing support for the disc 303.

[0034] A round rod 308 is fixedly connected to the front edge of a disc 303. A ring 309 is rotatably connected to the outside of the round rod 308. A swing rod 310 is fixedly connected to the lower outer end of the ring 309. A fixed rod 311 is fixedly connected to the lower right side of the inner side of the cleaning cart 1. A rectangular cylinder 312 is fixedly connected to the left end of the fixed rod 311. A sliding rod 313 is slidably connected to the inner side of the rectangular cylinder 312. A second round shaft 314 is connected to the upper end of the sliding rod 313. A striking hammer 315 is fixedly connected to the lower end of the sliding rod 313.

The front and rear ends of the second round shaft 314 are fixedly connected to the front and rear ends of the inner side of the groove. The outer side of the second round shaft 314 is rotatably connected to the inner side of the rotating hole. When the first motor 301 is started and drives the disc 303 to rotate clockwise, the circular rod 308 rotates clockwise along with the disc 303. When the circular rod 308 rotates to its highest point, it pulls the swing rod 310 and the sliding rod 313 to move upwards to their highest point, causing the hammer 315 to move away from the ground. Then, as the circular rod 308 rotates clockwise downwards, it drives the swing rod 310 to rotate around the second circular axis 314. At the same time, due to gravity, the hammer 315 falls and pulls the sliding rod 313 downwards until the circular rod 308 reaches its lowest point. At this point, the hammer 315 strikes the surface of the deck, knocking off large pieces of rust. Then, as the circular rod 308 rotates upwards, the swing rod 310 rotates and pulls the sliding rod 313 upwards, pulling the hammer 315 back up away from the deck. The disc 303 then stops rotating in preparation for the next strike.

[0035] The cleaning unit includes a second motor 401, a rotating shaft 402, a roller 403, brush bristles 404, and a collection box 405. The second motor 401 is fixedly connected to the rear of the cleaning cart 1, located to the left of the first motor 301. The rotating shaft 402 is fixedly connected to the front end of the output shaft of the second motor 401. The roller 403 is fixedly connected to the outer side of the rotating shaft 402. The brush bristles 404 are fixedly connected to the outer side of the roller 403. The collection box 405 is fixedly connected to the lower inner side of the cleaning cart 1, located to the left of the roller 403. The end of the brush bristles 404 away from the roller 403 is slidably connected to the deck surface, and the lower side of the collection box 405 is slidably connected to the deck surface. Thus, as the cleaning cart 1 moves to the right, the roller 403, driven by the second motor 401, sweeps the rust particles impacting the lower deck into the collection box 405 at the left end through the outer brush bristles 404.

[0036] The spray unit includes a first water tank 501, a connecting pipe 502, a first water storage pipe 503, and a spray head 504. The first water tank 501 is fixedly connected to the right side of the top inner side of the cleaning vehicle 1. The connecting pipe 502 is fixedly connected to the lower inner side of the first water tank 501. The first water storage pipe 503 is fixedly connected to the bottom inner side of the cleaning vehicle 1 at the left end of the receiving box 405. The spray head 504 is fixedly connected to the lower end of the first water storage pipe 503.

[0037] The rinsing unit includes a second water tank 601, a connecting pipe 602, a second water storage pipe 603, and a high-pressure nozzle 604. The second water tank 601 is fixedly connected to the top left side of the inner side of the cleaning vehicle 1. The connecting pipe 602 is fixedly connected to the lower end of the inner side of the second water tank 601.

The high-pressure nozzle 604 is fixedly connected to the lower end of the second water storage pipe 603.

[0038] Pumps are installed at the bottom of both the first water tank 501 and the second water tank 601. The upper end of the connecting pipe 502 is fixedly connected to the pump in the first water tank 501, and the lower end of the connecting pipe 502 is fixedly connected to the upper end of the first water storage pipe 503. The first water tank 501 contains rust remover. Thus, during the movement of the cleaning vehicle 1, the pump in the first water tank 501 is activated to draw the rust remover from the first water tank 501 into the connecting pipe 502, which then flows into the first water storage pipe 503. The rust remover can then be sprayed onto the deck through the spray nozzle 504 at the lower end for rust removal.

[0039] The upper end of the connecting pipe 602 is fixedly connected to the pump body inside the second water tank 601, and the lower end of the connecting pipe 602 is fixedly connected to the upper end of the second water storage pipe 603. Activating the pump body in the second water tank 601 allows clean water to be drawn from the second water tank 601 into the connecting pipe 602, then into the second water storage pipe 603, and finally sprayed onto the deck by the high-pressure nozzle 604, rinsing away the rust remover that has been used to remove rust from the deck.

[0040] Working principle: During use, the cleaning vehicle 1 is pushed to move on the deck. During the movement, the pump in the first water tank 501 at the upper part of the cleaning vehicle 1 is turned on, drawing the rust remover in the first water tank 501 into the connecting pipe 502, and then into the first water storage pipe 503. It is then sprayed onto the deck through the spray head 504 at the lower end. When the cleaning vehicle 1 moves to the deck with large rust spots, the pump in the first water tank 501 is turned off first, and then the first motor 301 is started to drive the disc 303 to rotate clockwise. The round rod 308 rotates clockwise along with the disc 303, pulling the swing rod 310 to move the sliding rod 313 up and down along the inner side of the rectangular cylinder 312, thereby driving the hammer 315 at the lower end to move up and down, striking the rust spots on the deck until the large rust spots are removed. After the rust is knocked off the deck, the first motor 301 is turned off, and then the second motor 401 and the pump in the first water tank 501 are started to continue pushing the cleaning cart 1. At this time, the output shaft of the second motor 401 rotates, driving the rotating shaft 402 to rotate, which in turn drives the outer roller 403 to rotate. The rotation of the outer brush 404 sweeps the rust blocks knocked off the deck into the collection box 405 at the left end. At the same time, the spray head 504 continues to spray rust remover on the deck to remove rust. After the rust on the deck is removed, the cleaning cart 1 is pushed again. At this time, only the pump in the second water tank 601 is turned on to draw the cleaning water in the second water tank 601 into the connecting pipe 602 and then into the second water storage pipe 603. It is then sprayed onto the deck by the high-pressure spray head 604 to rinse the rust remover off the deck.
