Description

Technical Field

[0001] The present invention relates to the technical field of ship bottom cleaning, in particular to a ship bottom cavitation jet cleaning machine. Background Art

[0002] When ships sail in the sea for a long time, barnacles, shells, seaweed, etc. are easily attached to the bottom of the ship, and rust is also likely to occur. Therefore, in order to ensure the stability of the ship's sailing and service life, the bottom of the ship needs to be cleaned and maintained regularly. The traditional method is for staff to use scrapers or steel brushes to clean the bottom of the ship underwater, but this is time-consuming and labor-intensive.

[0003] Therefore, there have been inventions such as an underwater ship bottom cavitation jet cleaning device disclosed in patent publication number CN219668449U and an underwater ship bottom cleaning robot disclosed in patent publication number CN222496602U to assist workers in cleaning the ship bottom.

[0004] However, during use, it was found that the existing cleaning equipment has a relatively simple structure, poor cleaning efficiency, and poor cleaning effect on stubborn dirt. In addition, although the barnacles and shells that fall after cleaning will sink to the seabed, the cleaning of multiple batches of ships causes a large amount of barnacles and shells to accumulate in the area, which is likely to affect the marine environment in the area, resulting in poor practicality. Therefore, there is an urgent need to improve the existing cleaning equipment to solve the above problems. Summary of the Invention

Then the staff controls the two sets of drive motors 5 respectively through the two sets of control handles 2, and then makes the two sets of tracks 4 run and move on the bottom of the ship, and then turns on the drainage pump 6. After the water is filtered by the filter plate 12, the water passes through the outward bamboo tube 11 and the drainage pump 6 into the cavitation generator 7, so that the cavitation generator 7 cavitates the water to form a large number of bubbles in the water. Then the water passes through the water pipe 8 and is sprayed to the bottom of the ship through multiple sets of cavitation nozzles 9, so that the bubbles quickly collapse on the bottom of the ship. The bottom of the ship is cleaned by the large amount of energy generated by the collapse of the bubbles, and the attachments that have fallen from the bottom of the ship in the frame 10 are sucked into the crushing box 16 by turning on the slurry pump 13. The drive motor 2 19 is turned on and the water is reduced. The speed reducer 18 is driven to rotate the two sets of crushing shafts 17 in opposite directions, crushing the attachments into particles. Then, the slurry pump 13 discharges the crushed material and water into the water spray pipe 2 14. At the same time, the driving motor 3 22 is operated to rotate the crushing blade 24, slowly crushing the dry ice blocks from bottom to top into dry ice blocks. In the crushing process, the electric control valve 29 is opened to allow the compressed air in the air storage tank 28 to enter the crushing box 23. The compressed air then carries the crushed dry ice into the water spray pipe 2 14, so that multiple sets of high-pressure nozzles 15 spray water, crushed attachments, dry ice particles and compressed air onto the bottom of the ship. The dry ice particles cool the bottom of the ship. At the same time, the dry ice particles and the crushed attachments collide with the attachments on the bottom of the ship, causing some attachments on the bottom of the ship to fall off. In the process of movement of the main shell 1, after the collision cleaning, cavitation cleaning is performed again to complete the cleaning work of the bottom of the ship, thereby improving the practicality of the equipment.

[0044] Example 2: Figures 1 to 10 As shown, a ship bottom cavitation jet cleaning machine, based on embodiment 1, further includes:

[0045] The adsorption mechanism includes a propeller 31 and a safety net 32. A reserved opening is provided in the middle of the main housing 1. The propeller 31 is installed in the reserved opening of the main housing 1. The safety net 32 is installed on the top of the main housing 1 to shield the propeller 31.

[0046] An air bag 33 is provided at the edge of the main shell 1;

[0047] The staff dives underwater with the equipment and holds two sets of control handles 2 to stick the bottom of the main shell 1 to the bottom of the ship, and supports the two sets of crawlers 4 on the hull, turns on the propeller 31, and discharges the water at the bottom of the main shell 1 from the top of the main shell 1, so that negative pressure is generated at the bottom of the main shell 1, so that the main shell 1 is sucked to the bottom of the ship, and adjusts the water absorption direction of the outward bamboo tube 11. After that, the staff controls the two sets of drive motors 5 respectively through the two sets of control handles 2, and then makes the two sets of crawlers 4 move. The water moves on the bottom of the ship, and then the drainage pump 6 is turned on. After the water is filtered by the filter plate 12, the water passes through the outward bamboo tube 11 and the drainage pump 6 into the cavitation generator 7, so that the cavitation generator 7 cavitates the water and forms a large number of bubbles in the water. After that, the water passes through the water spray pipe 8 and is sprayed to the bottom of the ship through multiple groups of cavitation nozzles 9, so that the bubbles collapse quickly on the bottom of the ship. The large amount of energy generated by the collapse of the bubbles cleans the bottom of the ship, and by turning on the slurry pump 13, the bottom of the ship in the frame 10 is cleaned. The fallen attachments are sucked into the crushing box 16, and the drive motor 2 19 is turned on. The transmission is output through the reducer 18, so that the two sets of crushing shafts 17 rotate in opposite directions, crushing the attachments into particles. Then the slurry pump 13 discharges the crushed materials and water into the water spray pipe 2 14. At the same time, the drive motor 3 22 is operated to rotate the crushing knife 24, slowly crushing the dry ice blocks from bottom to top into dry ice blocks. In the crushing process, the electric control valve 29 is opened to allow the compressed air in the air tank 28 to enter the crushing box 23. The compressed air then carries the crushed dry ice into the water spray pipe 2 14, so that multiple sets of high-pressure nozzles 15 spray water, crushed attachments, dry ice particles and compressed air onto the bottom of the ship. The dry ice particles cool the bottom of the ship. At the same time, the dry ice particles and the crushed attachments collide with the attachments on the bottom of the ship, causing some attachments on the bottom of the ship to fall off. In the process of movement of the main shell 1, after the impact cleaning, cavitation cleaning is performed again to complete the cleaning work of the bottom of the ship, thereby improving the practicality of the equipment.

[0048] The main functions achieved by the present invention are:

[0049] 1. By crushing and ejecting the attached objects, the use of equipment consumables is reduced, and multi-level cleaning is achieved to improve the cleaning effect;

[0050] 2. Since most of the attachments on the bottom of the ship are marine organisms, the impact of the increase of a large number of marine organisms on the surrounding environment can be reduced by crushing them;

[0051] 3. The structure is simple, which makes it easy to operate underwater and can be disassembled for maintenance.
