Description

Technical Field

[0001] This invention relates to the field of deck cleaning technology, and more particularly to a cleaning device for the deck of an FPSO vessel. Background Technology

[0002] The steel plates arranged horizontally on the hull of an FPSO vessel are called decks. The hull is divided into several layers by the decks. The uppermost deck, which is at the bow and stern, is called the upper deck. This deck needs to be kept watertight. This deck is prone to getting dirty after the crew walks on it. In addition, when seawater hits the hull, some seawater will also come onto this deck, resulting in a layer of dirt remaining on it. In order to protect the deck, it is necessary to clean it regularly.

[0003] For example, a patent with publication number CN118323383B, entitled "A Ship Deck Cleaning Device," was published on September 6, 2024. It includes a receiving frame with a cleaning cylinder on one side. A pair of connecting members are provided between the side of the cleaning cylinder and the receiving frame. The connecting members are arranged symmetrically around the center of the cleaning cylinder. A pair of support frames are arranged symmetrically around the center of the receiving frame. A positioning plate is installed at the top of the cleaning cylinder, and a first motor is installed at the top of the positioning plate. A rotating shaft is installed at the bottom of the output end of the first motor, and a cleaning head is installed at the bottom of the rotating shaft. This invention concentrates the cleaning fluid inside the cleaning cylinder during deck cleaning, facilitating deck cleaning. However, in the above-mentioned document, if the sealing ring at the bottom of the cleaning cylinder is not properly sealed, the cleaning fluid will still flow on the deck, reducing cleaning efficiency. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a cleaning device for the deck of an FPSO vessel to solve the problem of reduced cleaning efficiency.

[0005] To achieve the above objectives, the present invention provides a cleaning device for the deck of an FPSO vessel, comprising an inner cylinder, a mounting frame at the upper end of the inner cylinder, a cleaning motor mounted on the mounting frame, a cleaning shaft extending into the inner cylinder at the output end of the cleaning motor, a cleaning brush at the lower end of the cleaning shaft, a drive shaft connected to the cleaning shaft in the side wall of the inner cylinder, a drive gear connected to the drive shaft, a rotating ring gear externally meshing with the drive gear, and an annular groove for accommodating the rotating ring gear on the outer side wall of the inner cylinder. A squeegee is connected to the outer side of the rotating ring gear via a drive frame. An outer cylinder is fitted over the inner cylinder, and the inner and outer cylinders are connected by a connecting frame. The squeegee is located between the outer and inner cylinders. Sealing rings are provided at the lower ends of both the inner and outer cylinders. A support frame is provided outside the outer cylinder via a second lifting component, which is used for lifting the outer cylinder. The lower part of the support frame is provided with moving wheels. A bearing frame is provided outside the outer cylinder, and two water pumps are provided on the bearing frame. Each water pump is connected to a water pipe that extends into the inner cylinder.

[0006] Optionally, a receiving groove is provided on the lower part of one side of the cleaning brush plate, a sleeve scraper is provided on the outer sleeve of the cleaning brush plate, and a movable member is provided on the upper part of the cleaning brush plate. The movable member is connected to the sleeve scraper through a first lifting member. The movable member is used to control the sleeve scraper to move back and forth along the length direction of the cleaning brush plate so as to drive the sleeve scraper to scrape the cleaning brush plate and the deck. The first lifting member is used for the sleeve scraper to enter and exit the receiving groove.

[0007] Optionally, the sleeve scraper is provided with side scrapers symmetrically arranged with respect to the cleaning brush plate on both sides. Each side scraper is provided with a swinging member on one side of the sleeve scraper. The swinging member is used to control the swinging of the side scraper, thereby adjusting the tilt angle of the side scraper.

[0008] Optionally, the swinging component is a swing telescopic rod, with its two ends hinged to the side scraper and the sleeve scraper, respectively.

[0009] Optionally, two squeegees are provided. The squeegees are connected to the drive frame via tilting drive telescopic rods. When the second lifting component is activated, the outer cylinder moves upward, and the sealing rings under the outer cylinder and the inner cylinder leave the deck. The two tilting drive telescopic rods extend, so that the two squeegees contact the two sealing rings respectively and clean the sealing rings.

[0010] Optionally, a support frame is provided outside the outer cylinder, and two water pumps are provided on the support frame. Each water pump is connected to a water pipe that extends into the inner cylinder. The two water pumps are for water intake and drainage of the inner cylinder, respectively.

[0011] Optionally, the support frame is equipped with an air suction pump, which is connected to two air suction pipes that extend into the inner cylinder and the outer cylinder respectively.

[0012] Optionally, the cleaning shaft and the drive shaft are connected by a transmission belt, and the mounting bracket has a receiving cavity for accommodating the transmission belt.

[0013] Optionally, the rotating ring tooth is slidably connected to the annular groove, and an annular guide rail is provided at the top or bottom of the annular groove, with the rotating ring tooth slidably connected to the annular guide rail.

[0014] The beneficial effects of this invention are as follows: This invention provides a cleaning device for FPSO ship decks. When the ship deck needs cleaning, the support frame is moved to the deck to be cleaned, the second lifting component retracts, and the outer and inner cylinders move downwards, allowing the sealing rings to contact the deck surface, thus sealing the bottom ends of the outer and inner cylinders with the deck surface. The cleaning motor starts, driving the cleaning shaft and cleaning brushes to rotate. The cleaning brushes clean the deck. Simultaneously, a water pump starts, introducing external water or water containing cleaning fluid into the inner cylinder through a water pipe. The water and cleaning brushes work together to improve deck cleaning efficiency. The water injected into the inner cylinder is blocked by the sealing ring at the bottom of the inner cylinder, causing the water to remain inside. If the sealing ring at the bottom of the inner cylinder is not properly sealed to the deck, leakage occurs. The leaked water from the inner cylinder flows between the outer and inner cylinders. Under the rotation of the cleaning shaft, the inner wiping plate of the outer cylinder, through the meshing of gears and rotating ring teeth, performs a circular cleaning of the area between the outer and inner cylinders, preventing water leakage. Furthermore, the contact between the sealing ring at the bottom of the outer cylinder and the deck surface further increases the possibility of leakage prevention and improves cleaning efficiency.

[0020] like Figures 1 to 5As shown, a cleaning device for FPSO ship decks includes an inner cylinder 1. A mounting frame 3 is provided at the upper end of the inner cylinder 1, and a cleaning motor 4 is mounted on the mounting frame 3. The output end of the cleaning motor 4 is connected to a cleaning shaft 5 extending into the inner cylinder 1. A cleaning brush 6 is provided at the lower end of the cleaning shaft 5. A drive shaft 15, which is connected to the cleaning shaft 5 via a drive belt, is provided inside the side wall of the inner cylinder 1. A receiving cavity for accommodating the drive belt is provided inside the mounting frame 3. A drive gear 16 is connected to the drive shaft 15. A mounting cavity for mounting the drive gear 16, which communicates with the receiving cavity, is provided inside the side wall of the inner cylinder 1. The drive gear 16 is externally meshed with a rotating... The inner cylinder 1 has a rotating ring tooth 17. An annular groove is provided on the outer side wall of the inner cylinder 1 for placing the rotating ring tooth 17. The rotating ring tooth 17 is slidably connected to the annular groove. A smear 20 is connected to the outer side of the rotating ring tooth 17 through a drive frame 18. An outer cylinder 13 is provided on the inner cylinder 1. The inner cylinder 1 and the outer cylinder 13 are connected by a connecting frame 14. The smear 20 is located between the outer cylinder 13 and the inner cylinder 1. A sealing ring 2 is provided at the lower end of the inner cylinder 1 and the lower end of the outer cylinder 13. A support frame 26 is provided on the outer cylinder 13 through a second lifting member 27. The second lifting member 27 is used for lifting the outer cylinder 13. A moving wheel 28 is provided at the lower part of the support frame 26 for moving the support frame 26. A support frame 21 is provided outside the outer cylinder 13. Two water pumps 22 are provided on the support frame 21. Each water pump 22 is connected to a water pipe 23 that extends into the inner cylinder 1. The two water pumps 22 are for water intake and drainage of the inner cylinder 1, respectively. When one water pump 22 is started, it inputs external water or water containing cleaning solution into the inner cylinder 1 through a water pipe 23. The water and the cleaning brush 6 work together to improve the deck cleaning efficiency. When the water becomes turbid, the other water pump 22 is started to discharge the water in the inner cylinder 1 through another water pipe 23.

[0021] When the ship's deck needs cleaning, the support frame 26 is moved onto the deck to be cleaned, the second lifting component 27 retracts, and the outer cylinder 13 and inner cylinder 1 move downwards, causing the sealing ring 2 to contact the deck surface, thus sealing the bottom ends of the outer cylinder 13 and the inner cylinder 1 with the deck surface. The cleaning motor 4 starts, driving the cleaning shaft 5 and cleaning brush 6 to rotate. The cleaning brush 6 cleans the deck. At the same time, a water pump 22 starts, injecting external water or water containing cleaning solution into the inner cylinder 1 through a water pipe 23. The water and the cleaning brush 6 work together to improve the deck cleaning efficiency. Water entering the inner cylinder 1 is blocked by the sealing ring 2 under the inner cylinder 1, and the water will remain inside the inner cylinder 1. If the sealing ring 2 under the inner cylinder 1 is not properly sealed with the deck, leakage will occur. The leaked water from the inner cylinder 1 will flow between the outer cylinder 13 and the inner cylinder 1. Under the action of the cleaning shaft 5, the wiping plate 20 inside the outer cylinder 13 will drive the gear 16 to mesh with the rotating ring gear 17, thereby driving the wiping plate 20 to perform a circular cleaning of the area between the outer cylinder 13 and the inner cylinder 1, preventing water leakage. In addition, the contact between the sealing ring 2 under the outer cylinder 13 and the deck surface further increases the possibility of leakage prevention and improves the cleaning efficiency.

[0022] The cleaning brush 6 has a receiving groove 7 on one side of its lower part. The cleaning brush 6 is fitted with a sleeve scraper 8. The upper end of the cleaning brush 6 is provided with a moving part 9. The moving part 9 is connected to the sleeve scraper 8 through a first lifting part 12. The moving part 9 is used to control the sleeve scraper 8 to move back and forth along the length direction of the cleaning brush 6, so as to drive the sleeve scraper 8 to scrape the cleaning brush 6 and the deck. The first lifting part 12 is used for the sleeve scraper 8 to enter and exit the receiving groove 7. When the sleeve scraper 8 enters the receiving groove 7, the cleaning brush 6 can easily clean the deck. When the sleeve scraper 8 comes out of the receiving groove 7, the moving part 9 can control the sleeve scraper 8 to scrape the cleaning brush 6 and the deck.

[0023] An adjustable distance component is provided between the cleaning brush plate 6 and the cleaning rotating shaft 5 to facilitate adjustment of the distance between the lower end of the cleaning brush plate 6 and the cleaning rotating shaft 5. The adjustable distance component can be an adjustable telescopic rod. The extension and retraction of the adjustable telescopic rod facilitates control of the lifting and lowering of the cleaning brush plate 6, thereby adjusting the distance between the lower end of the cleaning brush plate 6 and the cleaning rotating shaft 5.

[0024] Both sides of the sleeve scraper 8 are provided with side scrapers 10 symmetrically arranged with respect to the cleaning brush plate 6. Each side scraper 10 has a swinging member 11 on one side of the sleeve scraper 8. The swinging member 11 is used to control the swinging of the side scraper 10, thereby adjusting the tilt angle of the side scraper 10. When the sleeve scraper 8 moves to the middle of the cleaning brush plate 6, the swinging member 11 controls the side scraper 10 to unfold horizontally, so that the side scraper 10 can scrape the deck. When the sleeve scraper 8 moves to the end of the cleaning brush plate 6, the swinging member 11 controls the side scraper 10 to be set vertically, so that the side scraper 10 can scrape the inner wall of the outer cylinder 13.

[0025] The swinging component 11 can be a swinging telescopic rod, with its two ends hinged to the side scraper 10 and the sleeve scraper 8, respectively. The moving component 9 can be a moving telescopic rod, which extends and retracts to facilitate the reciprocating movement of the sleeve scraper 8 along the length of the cleaning brush 6.

[0026] Two squeegees 20 are provided. The squeegees 20 are connected to the drive frame 18 via inclined drive telescopic rods 19. When the second lifting component 27 is activated, the outer cylinder 13 is moved upward. The sealing rings 2 under the outer cylinder 13 and the sealing rings 2 under the inner cylinder 1 are both removed from the deck. The two inclined drive telescopic rods 19 extend, so that the two squeegees 20 contact the two sealing rings 2 respectively and clean the sealing rings 2. The cleaning motor 4 is activated, which drives the drive frame 18 to rotate around the axis of the cleaning shaft 5, so that the two squeegees 20 clean the two sealing rings 2 in a ring shape respectively.

[0027] The support frame 21 is equipped with an air suction pump 24, which is connected to two air suction pipes 25 that extend into the inner cylinder 1 and the outer cylinder 13 respectively. When the air suction pump 24 is started, it sucks out the impurities inside the inner cylinder 1 and the outer cylinder 13, which facilitates further cleaning of the inner cylinder 1 and the outer cylinder 13.
