Description

Technical Field

[0001] This utility model relates to the field of underwater cleaning technology, specifically to a cleaning tray mechanism for underwater cleaning vehicles used for sludge suction and recovery. Background Technology

[0002] Ship cleaning is a crucial step in the shipping industry for maintaining hull performance and reducing energy consumption. Traditional high-pressure water jet cleaning suffers from high energy consumption, low efficiency, and potential damage to hull coatings, while manual cleaning faces challenges such as high operational risks and poor environmental performance. With the International Maritime Organization (IMO) strengthening its control over ship biofouling and the shipping industry's increasing demands for energy conservation and emission reduction, the development of efficient, environmentally friendly, and intelligent ship cleaning equipment has become an urgent industry need. In recent years, cavitation jet technology has attracted attention due to its low-pressure, high-efficiency, and non-destructive cleaning characteristics. The use of a mobile platform to move the cavitation jet cleaning disc close to the ship's hull for cleaning is widely adopted, but it still faces technical bottlenecks in adapting to complex curved surfaces and recovering contaminants. Therefore, during cleaning, the angle of the cleaning disc needs constant adjustment to ensure close contact with the ship's hull, but current technology has not effectively solved the problem of adaptive contact with the three-dimensional curved surface of the cleaning disc. Summary of the Invention

[0003] To overcome the shortcomings and deficiencies of existing technologies, the purpose of this utility model is to provide a cleaning disc mechanism for underwater cleaning vehicles used for sludge suction and recovery.

The cavitation jets remove stubborn dirt, and the swing mechanism achieves adaptive fitting of a three-dimensional curved surface. Combined with a negative pressure recovery suction pipe, it collects pollutants in real time, forming a cleaning-recovery closed-loop system. This effectively solves industry pain points such as insufficient cleaning coverage and secondary pollution in existing technologies, providing an innovative solution for green ship maintenance.

[0026] See Figure 1-5 A cleaning disc mechanism for underwater cleaning vehicle used for sludge suction and recovery includes a mounting plate 1, a swing mechanism, a connector 4, and a set of cleaning disc assemblies 5. The swing mechanism includes a front swing assembly 2 and a rear swing assembly 3. The two cleaning disc assemblies 5 are connected by the connector 4. The front end of the mounting plate 1 is connected to one end of the front swing assembly 2, and the other end of the front swing assembly 2 is hinged to one side of the connector 4. The rear end of the mounting plate 1 is movably hinged to one end of the rear swing assembly 3, and the other end of the rear swing assembly 3 is hinged to the other side of the connector 4, so that the connector 4 can swing back and forth relative to the mounting plate 1.

[0027] In this embodiment, the cleaning disc assembly 5 innovatively integrates a cavitation jet 53 and a multi-degree-of-freedom swing mechanism. The cavitation jet 53 removes stubborn dirt, and the elastic front swing assembly 2 and rear swing assembly 3 enable the cleaning disc 51 to achieve three-dimensional curved surface adaptive fitting. Combined with the suction pipe 55 with negative pressure recovery, pollutants are collected in real time, forming a cleaning-recycling closed-loop system. This effectively solves the industry pain points of insufficient cleaning coverage and secondary pollution in existing technologies, and provides an innovative solution for green ship maintenance.

[0028] In this embodiment, the front swing assembly 2 includes a first support rod 21, a second support rod 22, a rotating sleeve 23, a lower pressure plate 24, a first spring 25, and a locking member 26. The same end of the first support rod 21 and the second support rod 22 are respectively fixed to both ends of the rotating sleeve 23. The first spring 25 is sleeved on the outer periphery of the first support rod 21 or the second support rod 22 (one end of the first spring 25 abuts against the connecting member 4, and the other end of the first spring 25 abuts against the lower pressure plate 24). The other ends of the first support rod 21 and the second support rod 22 respectively pass through the lower pressure plate 24 and extend out of the upper end surface of the lower pressure plate 24 and are locked by the locking member 26. The lower pressure plate 24 can slide along the axial direction of the first support rod 21 and the second support rod 22. The lower pressure plate 24 is fixed to the lower end surface of the mounting plate 1. The rotating sleeve 23 is movably hinged to the connecting member 4 through a rotating shaft.

[0029] In this embodiment, the rear swing assembly 3 includes a first rotating shaft 31, a second rotating shaft 32, a third support rod 33, a fourth support rod 34, a set of abutment rings 35, and a second spring 36. The lower end face of the mounting plate 1 is provided with a first bearing seat 11, and the first rotating shaft 31 is rotatably sleeved on the first bearing seat 11. The upper end face of the connector 4 is provided with a second bearing seat 41 corresponding to the first bearing seat 11, and the second rotating shaft 32 is rotatably sleeved on the second bearing seat 41. The third support rod 33 and the fourth support rod 34... The lower ends of both are connected to the second rotating shaft 32. The upper ends of the third support rod 33 and the fourth support rod 34 pass through the first rotating shaft 31 and extend out of the upper end of the first rotating shaft 31. The second spring 36 is sleeved on the outer periphery of the third support rod 33 or the fourth support rod 34. The abutment ring 35 is sleeved on the upper end of the third support rod 33 and the fourth support rod 34. The lower end of the second spring 36 abuts against the second rotating shaft 32, and the upper end of the second spring 36 abuts against the abutment ring 35.

[0030] In this embodiment, the mounting plate 1 has a through hole 12 at the position of the upper end of the third support rod 33 and the fourth support rod 34.

[0031] In this embodiment, the forward swing assembly 2 adopts the specific structure described above. When the underwater cleaning vehicle, carrying the cleaning disc 51 mechanism, is pressed against the surface of the hull to be cleaned, the tightness of the contact between the cleaning disc 51 and the bottom of the hull can be automatically adjusted back and forth according to the unevenness of the hull surface. Specifically, during adjustment, since the first support rod 21 and the second support rod 22 can rotate with the rotating sleeve 23 relative to the connecting piece 4, the distance between the cleaning disc 51 and the mounting plate 1 can be adjusted to adapt to the uneven hull surface. When the first support rod 21 and the second support rod 22 rotate with the rotating sleeve 23, causing the cleaning disc 51 to swing forward, the first spring 25 will be compressed. At the same time, the first... The distance between the connector 4 and the mounting plate 1 can be shortened by sliding the support rod 21 and the second support rod 22 upward relative to the lower pressure plate 24; while the cleaning disc 51 swings forward, the third support rod 33 and the fourth support rod 34 will also rotate synchronously in the direction of rotation of the first support rod 21 and the second support rod 22. Specifically, the third support rod 33 and the fourth support rod 34 can move together with the connector 4, so that the third support rod 33 and the fourth support rod 34 rotate relative to the first rotating shaft 31. At the same time, due to the third support rod 33 and the fourth support rod 34, the second spring 36 is stretched under the action of elastic force to provide downward pressure for the cleaning disc 51 to stick to the surface of the hull. When the cleaning disc 51 swings backward, the first support rod 21 and the second support rod 22 slide downward relative to the lower pressure plate 24, which extends the distance between the connector 4 and the mounting plate 1. At the same time as the cleaning disc 51 swings backward, the third support rod 33 and the fourth support rod 34 will also rotate synchronously in the same direction as the first support rod 21 and the second support rod 22. Specifically, the third support rod 33 and the fourth support rod 34 can move together with the connector 4, so that the third support rod 33 and the fourth support rod 34 rotate relative to the first rotating shaft 31. At the same time, as the third support rod 33 and the fourth support rod 34 slide upward relative to the first rotating shaft 31 during the rotation, the distance between the first rotating shaft 31 and the second rotating shaft 32 is shortened. This causes the second spring 36 to be compressed under pressure, providing pressure for the cleaning disc 51 to stick to the hull surface, adapting to the curved surface of the hull, and realizing the function of the cleaning disc 51 swinging back and forth.

[0032] In this embodiment, each of the cleaning disc assemblies 5 includes a cleaning disc 51, a brush 52, a cavitation jet 53, and a suction pipe 55. The brush 52 is arranged around the opening side of the cleaning disc 51. The cavitation jet 53 is located inside the cleaning disc 51 and penetrates the top of the cleaning disc 51. The suction pipe 55 is located on the upper end face of the cleaning disc 51, and one end of the suction pipe 55 extends into the cleaning disc 51. The cavitation jet 53 is provided with a plurality of cavitation nozzles 54 arranged in a circumferential array. The cavitation nozzles 54 are inclined toward the opening side of the cleaning disc 51. A flow guide shroud 56 is also provided inside the cleaning disc 51, and the cavitation nozzles 54 are located inside the flow guide shroud 56.

[0033] In this embodiment, the cleaning disc assembly 5 adopts the specific structure described above. During operation, the cleaning disc 51 is attached to the surface of the hull to be cleaned, which can fix and protect the cavitation jet 53 for stable cleaning. The cavitation jet 53 can generate cavitation during operation to efficiently clean ship impurities. The guide shroud 56 can play a role in cleaning isolation and improve recovery efficiency. The brush 52 is used to isolate pollutants and ensure cleaning effect.

[0034] In this embodiment, the cleaning disc 51 is fixed to the ROV (Remotely Operated Vehicle) body via the mounting plate 1, ensuring the stability and reliability of the cleaning disc 51 during underwater operation. The cleaning disc 51 is brought into contact with the hull to be cleaned via the elastic front swing assembly 2 and rear swing assembly 3, allowing the cleaning disc 51 to automatically adjust its contact with the hull bottom according to the unevenness of the hull surface. The thrust of the first spring 25 and the second spring 36 effectively ensures that the cleaning disc 51 can adhere tightly to the hull on various terrains, achieving effective cleaning. Specifically, the cleaning disc 51 undergoes slight tilt angle adjustments under forward and backward force, enhancing its adaptability to complex terrain and ensuring cleaning effectiveness. The cavitation jet 53 is connected to a high-pressure water pipe and drives the cavitation nozzle 54 to rotate, cleaning a circular area. The cavitation nozzle 54 emits fine bubbles, forming a cavitation jet beam. When these jet beams impact the hull surface, the generated bubbles rapidly expand and burst, producing strong vibrations that break down and remove dirt and organisms attached to the hull bottom. In addition, the suction pipe 55 is connected to a recycling pump used in conjunction with it. When the recycling pump is working, the pollutants on the deck to be cleaned are recycled to the shore through the suction pipe 55, thus forming a closed-loop system of cleaning and recycling.

[0035] The work process is as follows:

[0036] Start-up phase: The ROV carrying the cleaning disc 51 approaches the target hull and adjusts the position of the cleaning disc 51 through remote control to ensure initial contact with the bottom of the hull.

[0037] Adaptive adjustment: The front swing assembly 2 and the rear swing assembly 3 automatically adjust according to the terrain of the bottom of the boat to ensure that the cleaning disc 51 fits tightly against the bottom of the boat. At the same time, the up and down floating of the first spring 25 and the second spring 36 is finely adjusted to adapt to the tilt or irregular surface of the bottom of the boat.

[0038] Cleaning process: The cleaning disc 51 starts working, the cavitation jet 53 is activated, and the cavitation jet beam is emitted from the cavitation nozzle 54 to break up and clean the deposits on the bottom of the ship.

[0039] Continuous monitoring and adjustment: The ROV operator monitors the cleaning process through a camera and adjusts the position and angle of the cleaning disc 51, as well as the intensity and direction of the cavitation jet 53, in a timely manner according to the cleaning effect and changes in the bottom terrain.

[0040] Sewage suction process: The ROV operator starts the recovery pump, and the pollutants are recovered to the shore through the suction pipe 55.

[0041] Cleaning complete: Once the bottom surface of the ship reaches the predetermined cleanliness standard, the operator stops the rotation of the cleaning disc 51 and the launch of the cavitation jet 53, retracts the cleaning disc 51, and completes the cleaning task.

[0042] Evacuation phase: The ROV, carrying the cleaning tray 51, evacuates the work area and returns to a safe location or proceeds to the next cleaning task.

[0043] In this embodiment, the cleaning disc 51 is provided with several evenly distributed movable casters 57 on the open side, which facilitates the movement of the cleaning disc 51 with the ROV.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
