Description

Technical Field

[0001] The present invention relates to the technical field of ship construction, in particular to an automatic cleaning device for ship parts. Background Art

[0002] As a large water-based vehicle, ships' components and parts are inevitably corroded by various pollutants, such as seawater, oil, and dust, over long periods of use. These pollutants not only affect the ship's appearance and performance but can also accelerate corrosion and wear of components, shortening the ship's service life. Therefore, regular cleaning and maintenance of ship parts is crucial to ensuring safe operation and extending the ship's service life.

[0003] Traditional cleaning methods for ship parts rely primarily on manual cleaning and simple mechanical assistance. However, manual cleaning is labor-intensive and time-consuming. Furthermore, due to the wide variety and shapes of ship parts, as well as the presence of hard-to-reach corners and crevices, manual cleaning is often difficult to achieve. Therefore, an automatic cleaning device for ship parts was proposed. Summary of the Invention

[0004] The present invention aims to solve the technical problem of how to effectively clean the corners and gaps of ship parts, reduce manpower and improve the cleaning effect, and provides an automatic cleaning device for ship parts.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0021] The controller is arranged on the side of the main box away from the liquid storage tank. The controller is fixedly connected to the main box and is electrically connected to the ultrasonic transducer, the water pump and the cleaning device.

[0022] When using this device to clean ship parts, the worker first adds an appropriate amount of water to the cleaning tank, ensuring that the water level does not exceed the plane of the two crossbars. The worker then uses the cleaning device to immerse the ship parts in the water in the cleaning tank. The worker then uses the controller to activate the ultrasonic transducer to clean the ship parts. After a period of time, the worker uses the controller to activate the water pump, which works by pumping the water and dirt in the cleaning tank through the suction pipe, the water pump, and the drain pipe into the liquid storage tank.

[0145] The dirt on the filter screen 9 can be effectively cleaned by the bristles 36 to prevent the filter screen 9 from being blocked.

[0146] Working principle: When using the device to clean ship parts, the staff first adds an appropriate amount of water to the cleaning box 5 so that the water level in the cleaning box 5 does not exceed the plane of the two horizontal plates 6. Then the staff places the ship parts in the cleaning basket 17. Then the staff starts the reversing motor 13 through the controller 38. The rotating shaft of the reversing motor 13 drives the first threaded rod 14 to rotate forward. The first threaded rod 14 drives the first gear 18 to rotate forward, driving the two sliders 16 to move downward along the vertical rod 15. The two sliders 16 drive the cleaning basket 17 to move downward. The cleaning basket 17 drives the ship parts to move downward so that the ship parts are submerged under the water. Then the staff turns off the reversing motor 13 and turns on the ultrasonic transducer 4.

[0149] After using ultrasound to clean ship parts for a period of time, the staff turns off the ultrasonic transducer 4 and turns on the water pump 10 through the controller 38. The water pump 10 works so that the water and dirt in the cleaning box 5 pass through the water pipe 11, the water pump 10, and the drain pipe 12 in turn into the liquid storage tank 7.

After a period of time, the staff turns off the water pump 10 through the controller 38.

[0150] When it is necessary to move ship parts upward, the staff controls the rotating shaft of the reversing motor 13 to rotate in the opposite direction through the controller 38. The rotating shaft of the reversing motor 13 drives the first threaded rod 14 to rotate in the opposite direction. The first threaded rod 14 drives the first gear 18 to rotate in the opposite direction, driving the two sliders 16 to move upward along the vertical rod 15.

Finally, the staff turns off the reversing motor 13 through the controller 38, and then the staff can take out the ship parts.

[0152] When the first rotating shaft 25 drives the first bevel gear 30 to rotate in the opposite direction, the first bevel gear 30 drives the second bevel gear 34 to rotate in the opposite direction, the second bevel gear 34 drives the second threaded rod 32 to rotate in the opposite direction, the second threaded rod 32 drives the brush plate 35 to move left along the round rod 33, the brush plate 35 drives the several bristles 36 to move left, and the bristles 36 clean the filter screen 9 to prevent the filter screen 9 from being blocked.
