Description

Technical Field

[0001] The invention relates to the technical field of propeller ultrasonic cleaning, in particular to an ultrasonic cleaning system for a shuttle tanker propeller. Background Art

[0002] The propellers of ships sailing at sea will be in contact with seawater for a long time during their service. Over time, a large number of marine organisms will adhere to the surface. Biological adhesion will not only destroy the fluid line shape of the propeller, increase resistance and reduce efficiency, but also produce corrosive extracellular secretions due to the metabolism of the adhered organisms, causing corrosion to the propeller surface, thereby shortening the service life of the propeller and increasing the cost of propeller maintenance.

[0003] Chinese patent CN109080790B discloses an underwater automatic propeller cleaning device and a cleaning method thereof, including a high-pressure water supply device placed on the shore, the high-pressure water supply device is connected to the underwater robot through an underwater robot communication cable and a high-pressure water pipe, an underwater manipulator is installed at the output end of the underwater robot, and the underwater manipulator is installed with a cavitation cleaning device through a connecting device, and the output port of the cavitation cleaning device is docked with the propeller blade. The underwater robot is equipped with an underwater manipulator to clamp the cavitation cleaning device with a connecting device to eject high-pressure water provided by the high-pressure water supply device to clean the propeller according to the cavitation principle. The three positioning rods carried by the underwater robot use their own propellers to generate lateral thrust to complete positioning relative to the propeller, the underwater manipulator clamps the cavitation cleaning device to complete the cleaning of the local area of ​​the propeller blade surface, the underwater robot moves along a preset path to clean the entire propeller blade surface, and rotates the propeller to complete the cleaning of all the propeller blade surfaces.

Specific embodiments

[0030] To further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 10As shown in the figure, a shuttle tanker propeller ultrasonic cleaning system includes an ultrasonic cleaning main control box 7 and an ultrasonic cleaning device. The ultrasonic cleaning device is installed between the oil tanker transmission shaft 8 and the propeller 9. The ultrasonic cleaning main control box 7 is connected to the ultrasonic cleaning device. The ultrasonic cleaning device includes a stable conduction shaft 1 installed between the oil tanker transmission shaft 8 and the propeller 9. A fixed mounting frame 2 is installed on the outer side of the stable conduction shaft 1. A rotating conduction mechanism 4 and an ultrasonic device 5 are installed on the fixed mounting frame 2. A multi-section pressing control device 3 is also installed on the fixed mounting frame 2. A friction dust cleaning device 6 is installed beside the ultrasonic device 5 and the stable conduction shaft 1.

[0032] The ultrasonic cleaning main control box 7 is connected to the ultrasonic cleaning device through a cable. When the tanker engine is started, the tanker transmission shaft 8 will rotate. When the tanker transmission shaft 8 rotates, it will drive the stable conduction shaft 1 to rotate synchronously. When the stable conduction shaft 1 rotates, it will drive the propeller 9 to rotate synchronously. The long-term rotation of the propeller 9 in seawater will cause a large number of marine organisms to adhere to the surface. The adhesion of marine organisms to the surface will cause the tanker's speed to decrease. In order to ensure the tanker's sailing speed, the staff will start the multi-stage push control device 3 through the ultrasonic cleaning main control box 7. When the multi-stage push control device 3 is started, it will first push the contact end of the rotating conduction mechanism 4 to contact the rotating stable conduction shaft 1. The rotating conduction mechanism 4 can adaptively engage with the rotating stable conduction shaft 1, so that the rotating conduction mechanism 4 will rotate accordingly. When the rotating conduction mechanism 4 rotates, it will drive the ultrasonic device 5 to rotate synchronously. When the ultrasonic device 5 rotates, it will rub the cleaning device 6 The cleaning end will be inserted between the ultrasonic device 5 and the stable conduction shaft 1. The rotation of the ultrasonic device 5 and the stable conduction shaft 1 will rub against the cleaning end of the friction cleaning device 6, which can effectively ensure that the docking end of the ultrasonic device 5 and the stable conduction shaft 1 remains clean. After the docking area of ​​the ultrasonic device 5 and the stable conduction shaft 1 is cleaned, the friction cleaning device 6 will be reset, and the multi-stage pushing control device 3 will continue to push. When the multi-stage pushing control device 3 continues to push, it will drive the rotating ultrasonic device 5 to collide with the stable conduction shaft 1. After the ultrasonic device 5 conflicts with the stable conduction shaft 1, the ultrasonic device 5 will emit ultrasonic waves to the stable conduction shaft 1, and the stable conduction shaft 1 will stably transmit the emitted ultrasonic waves to the rotating propeller 9. When the ultrasonic wave is emitted from the propeller 9 and contacts with seawater, it will generate bubbles. The shock wave generated by the bursting of the bubbles can achieve the effect of cleaning and flushing the inner and outer surfaces of the workpiece. On the one hand, ultrasonic waves destroy dirt and adsorbents on the surface of the cleaning parts, and on the other hand, they can cause the dirt layer to be peeled off due to fatigue damage. The vibration of gas bubbles scrubs the solid surface. Once there is a gap in the dirt layer to drill, the bubbles immediately drill in and vibrate to make the dirt layer fall off. After the propeller 9 is cleaned, the multi-stage pushing control device 3 will be reset. After the multi-stage pushing control device 3 is reset, the rotating conduction mechanism 4 and the ultrasonic device 5 will be reset accordingly, so that the rotating conduction mechanism 4 and the ultrasonic device 5 stop rotating, which effectively reduces the failure caused by long-term rotation of the equipment.

[0033] See also Figure 2 and Figure 3 As shown, the outer wall of the stable conduction shaft 1 is provided with a plurality of limit installation grooves, and directional conduction bars 11 are installed inside the limit installation grooves. The contact surfaces of the directional conduction bars 11 and the stable conduction shaft 1 are provided with an insulating layer. A docking conduction ring 12 is also installed on the directional conduction bar 11, and a positioning clamping assembly 13 is installed on the side of the docking conduction ring 12.

[0034] The stable conduction shaft 1 is installed between the transmission shaft 8 of the oil tanker and the propeller 9. The multiple limit installation grooves of the stable conduction shaft 1 are used for limit installation of the directional conduction strips 11. The directional conduction strips 11 are used for conducting ultrasonic waves. The isolation layer outside the directional conduction strips 11 is used for wrapping the directional conduction strips 11. The isolation layer can effectively make the ultrasonic waves transmitted by the directional conduction strips 11 propagate to the specified area. The output end of the directional conduction strip 11 is in contact connection with the propeller 9. A docking conduction ring 12 is installed on the input end of the directional conduction strip 11. The docking conduction ring 12 is used for docking with the ultrasonic device 5, so that the ultrasonic waves emitted by the ultrasonic device 5 can be effectively conducted into the directional conduction strip 11. The positioning and clamping component 13 on the side of the docking conduction ring 12 is used for docking and clamping the contact end of the rotating conduction mechanism 4.

[0035] See Figure 3 and Figure 4 As shown, the docking conduction ring 12 includes a plurality of assembled conduction blocks 121. The assembled conduction blocks 121 correspond to the directional conduction strips 11 one by one. A docking convex block 1211 is provided at the top of the assembled conduction block 121. A docking slot 1212 is provided at the bottom of the assembled conduction block 121. Elastic connection blocks 122 are installed at the gaps between the assembled conduction blocks 121.

[0036] The docking conduction ring 12 is assembled and connected by the assembled conduction blocks 121 and the elastic connection blocks 122. The elastic connection blocks 122 at the gaps between the assembled conduction blocks 121 can effectively improve the adaptability of the fitting installation. The docking slot 1212 at the bottom of the assembled conduction block 121 is used for docking and installing the directional conduction strip 11. The docking convex block 1211 at the top of the assembled conduction block 121 is used for docking and contacting the ultrasonic device 5. When the ultrasonic device 5 contacts the assembled conduction block 121, the ultrasonic waves emitted by the ultrasonic device 5 can effectively conduct the sound waves to the directional conduction strip 11 through the assembled conduction block 121.

[0037] See Figure 3 and Figure 4 As shown, the positioning and clamping component 13 includes a plurality of positioning and clamping blocks 131 installed on the side of the assembled conduction block 121. Guide chamfers 132 are provided on both sides of the positioning and clamping block 131. A plug-in notch 133 is provided on the outside of the positioning and clamping block 131.

[0038] When the transmission shaft 8 of the oil tanker rotates, it drives the stable conduction shaft 1 to rotate synchronously. When the stable conduction shaft 1 rotates, it drives the propeller 9 to rotate synchronously. When the stable conduction shaft 1 rotates, it drives the docking conduction ring 12 and the positioning clamping block 131 to rotate synchronously. When it is necessary to drive the ultrasonic device 5 to rotate, the multi-stage pushing control device 3 preferentially pushes the abutting end of the rotation conduction mechanism 4 to contract and move. The abutting end of the rotation conduction mechanism 4 contracts to a specified position and stops. When the positioning clamping block 131 rotates, the guiding bevel 132 guides the abutting end of the rotation conduction mechanism 4 to move upward. When the abutting end of the rotation conduction mechanism 4 moves to the insertion bayonet 133 of the positioning clamping block 131, the abutting end of the rotation conduction mechanism 4 is inserted into the insertion bayonet 133, and when the abutting end of the rotation conduction mechanism 4 is inserted into the insertion bayonet 133, the rotation conduction mechanism 4 rotates accordingly.

[0039] See Figure 2 and Figure 5 As shown, the multi-stage pushing control device 3 includes a first telescopic mounting frame 31 mounted on the fixed mounting frame 2. A first limit guide post 32 is installed between the first telescopic mounting frame 31 and the fixed bracket. A multi-stage pushing ring 34 is mounted on the first telescopic mounting frame 31. The multi-stage pushing control device 3 further includes a first linear driver 33 that pushes the first telescopic mounting frame 31 to move.

[0040] The first limit guide post 32 is used to limit and guide the movement of the first telescopic mounting frame 31. The first linear driver 33 is preferably an electric push rod. When it is necessary to push and move the rotation conduction mechanism 4 and the ultrasonic device 5 in a segmented manner, the electric push rod pushes the first telescopic mounting frame 31 to move. When the first telescopic mounting frame 31 moves, it pushes the multi-stage pushing ring 34 to move. When the multi-stage pushing ring 34 moves to the outside of the rotation conduction mechanism 4, the abutting end of the rotation conduction mechanism 4 contracts and moves. When the multi-stage pushing ring 34 moves to the outside of the ultrasonic device 5, the sound-emitting end of the ultrasonic device 5 abuts against the stable conduction shaft 1. Effective segmented pushing moves the rotation conduction mechanism 4 and the ultrasonic device 5.

[0041] See Figure 5 and Figure 6 As shown, the multi-stage pushing ring 34 includes a second pushing ring 342 mounted on the first telescopic mounting frame 31. A first pushing ring 341 is mounted inside the second pushing ring 342. Pushing inclined surfaces 344 are provided inside both the first pushing ring 341 and the second pushing ring 342. A plurality of second limit guide posts 343 are installed between the first pushing ring 341 and the second pushing ring 342. A first pushing spring 345 is mounted on the second limit guide posts 343.

[0042] When the electric push rod pushes the first telescopic mounting bracket 31 to move, it will push the second pressing ring 342 to move. When the second pressing ring 342 moves, it can effectively push the first pressing ring 341 to move through the first pressing spring 345. When the first pressing ring 341 moves to the outside of the rotation transmission mechanism 4, the pressing inclined surface 344 of the first pressing ring 341 will push the contact end of the rotation transmission mechanism 4 to contract and move. When the electric push rod continues to push the first telescopic mounting bracket 31 to move, the first pressing spring 345 will contract and squeeze, so that the second pressing ring 342 moves to the outside of the ultrasonic device 5, and the pressing inclined surface 344 on the second pressing ring 342 will push the sound emitting end of the ultrasonic device 5 to contract and move synchronously.

[0043] See Figure 2 and Figure 7 As shown in the figure, the rotation transmission mechanism 4 includes a positioning mounting ring 41 mounted on the fixed mounting bracket 2. A rotation mounting ring 42 is mounted on the positioning mounting ring 41. A plurality of first limiting mounting holes are provided on the rotation mounting ring 42, and a plurality of pressing and clamping members 43 are mounted on the first limiting mounting holes.

[0044] A plurality of pressing and clamping members 43 are telescopically mounted in the first limiting mounting holes of the rotation mounting ring 42. When the first pressing ring 341 of the multi-section pressing ring 34 moves to the outside of the rotation mounting ring 42, the pressing inclined surface 344 of the first pressing ring 341 will contact the tops of the plurality of pressing and clamping members 43. When the pressing inclined surface 344 of the first pressing ring 341 contacts the pressing and clamping member 43, it will push the pressing and clamping member 43 to contract and move synchronously. When the pressing and clamping member 43 contracts, it will be positioned and clamped with the positioning clamping assembly 13. When the positioning clamping assembly 13 rotates, it will drive the rotation mounting ring 42 to rotate synchronously through the pressing and clamping member 43. When the rotation mounting ring 42 rotates, it will drive the ultrasonic device 5 to rotate synchronously, effectively conducting the rotational force.

[0045] See Figure 7 and Figure 8 As shown in the figure, the pressing and clamping member 43 includes a sliding mounting sleeve 431 mounted on the first limiting mounting hole. A first sliding ball 432 is mounted on the top of the sliding mounting sleeve 431. A second pressing spring 435 is mounted between the sliding mounting sleeve 431 and the rotation mounting ring 42. A sliding mounting column 434 is mounted inside the sliding mounting sleeve 431. A telescopic clamping block 433 is mounted on the sliding mounting column 434. A third pressing spring 436 is mounted between the sliding mounting column 434 and the sliding mounting sleeve 431.

[0046] When the first pressing ring 341 of the multi-section pressing ring 34 moves to the outside of the rotation mounting ring 42, the pressing inclined surface 344 of the first pressing ring 341 will abut against the first sliding ball 432 at the top of the sliding mounting sleeve 431. The first sliding ball 432 can effectively reduce the friction force, and the pressing inclined surface 344 can effectively push the sliding mounting sleeve 431 to move downward. When the sliding mounting sleeve 431 moves downward, the second pressing spring 435 will be compressed. When the sliding mounting sleeve 431 descends, it will drive the sliding mounting column 434 and the telescopic clamping block 433 to move downward synchronously. The telescopic clamping block 433 stops when it descends to the position of the positioning clamping block 131. When the positioning clamping block 131 rotates, the guiding inclined angle 132 on the side will abut against the telescopic clamping block 433, causing the telescopic clamping block 433 to move upward. When the telescopic clamping block 433 moves upward, the third pressing spring 436 will be compressed. When the telescopic clamping block 433 moves to the insertion bayonet 133 of the positioning clamping block 131, the telescopic clamping block 433 will directly insert, so that the telescopic clamping block 433 rotates synchronously with the positioning clamping block 131.

[0047] See Figure 2 and Figure 9 As shown in and, the ultrasonic device 5 includes a connection mounting ring 51 mounted on the rotation mounting ring 42. A plurality of second mounting holes are provided on the connection mounting ring 51. Telescopic mounting columns 52 are installed in the second mounting holes. A fourth pressing spring 55 is installed between the telescopic mounting column 52 and the connection mounting ring 51. A second sliding ball 53 is installed at the top of the telescopic mounting column 52. An installation frame 54 is installed below the telescopic mounting column 52. An ultrasonic generator 56 is installed inside the installation frame 54.

[0048] The pressing inclined surface 344 of the first pressing ring 341 abuts against the tops of the plurality of pressing and clamping members 43. When the pressing inclined surface 344 of the first pressing ring 341 abuts against the pressing and clamping member 43, the pressing and clamping member 43 will contract and move to dock with the positioning clamping assembly 13, causing the rotation transmission mechanism 4 to rotate with the positioning clamping assembly 13. When the rotation mounting ring 42 of the rotation transmission mechanism 4 rotates, it will drive the connection mounting ring 51 to rotate synchronously. When the connection mounting ring 51 rotates, when the pressing inclined surface 344 of the second pressing ring 342 abuts against the second sliding ball 53 on the telescopic mounting column 52, the telescopic mounting column 52 will move downward, and the fourth pressing spring 55 will be compressed. When the telescopic mounting column 52 moves downward, it will push the installation frame 54 to move downward. When the installation frame 54 moves downward, it will push the ultrasonic generator 56 to abut against the rotation docking conduction ring 12. The ultrasonic generator 56 emits ultrasonic waves, which can effectively conduct to the propeller 9 to clean the surface dirt.

[0049] See Figure 2 and Figure 10As shown, the friction dust cleaning device 6 includes a second telescopic mounting frame 61 mounted on the fixed mounting frame 2. A third limit guide post 62 is mounted between the second telescopic mounting frame 61 and the fixed mounting frame 2. A ring-shaped insertion plate is mounted on the second telescopic mounting frame 61, and a cleaning sponge 63 sleeve is mounted on the ring-shaped insertion plate. The friction dust cleaning device 6 further includes a second linear driver 64 for driving the second telescopic mounting frame 61 to move telescopically.

[0050] The second linear driver 64 is preferably an electric push rod. When the multi-stage pressing control device 3 is started, it will first push the contact end of the rotation conduction mechanism 4 against the rotating stable conduction shaft 1. The rotation conduction mechanism 4 can adaptively engage with the rotating stable conduction shaft 1, causing the rotation conduction mechanism 4 to rotate accordingly. When the rotation conduction mechanism 4 rotates, it will drive the ultrasonic device 5 to rotate synchronously. When the ultrasonic device 5 rotates, the electric push rod will push the second telescopic mounting frame 61 to extend and move. When the second telescopic mounting frame 61 extends and moves, it will drive the cleaning sponge 63 sleeve on the ring-shaped insertion plate to insert between the ultrasonic device 5 and the stable conduction shaft 1. The rotation of the ultrasonic device 5 and the stable conduction shaft 1 will contact the cleaning sponge 63 sleeve, and the cleaning sponge 63 sleeve can effectively clean the docking area between the ultrasonic device 5 and the stable conduction shaft 1. After the docking area between the ultrasonic device 5 and the stable conduction shaft 1 is cleaned, the electric push rod will drive the cleaning sponge 63 sleeve to reset. After the cleaning sponge 63 sleeve is reset, the ultrasonic device 5 will contact the stable conduction shaft 1, effectively ensuring the transmission effect.

[0051] Specific working principle:

[0052] The ultrasonic cleaning main control box 7 is connected to the ultrasonic cleaning device through a cable. When the tanker engine is started, the tanker transmission shaft 8 will rotate. When the tanker transmission shaft 8 rotates, it will drive the stable conduction shaft 1 to rotate synchronously. When the stable conduction shaft 1 rotates, it will drive the propeller 9 to rotate synchronously. The long-term rotation of the propeller 9 in seawater will cause a large number of marine organisms to adhere to the surface. The adhesion of marine organisms to the surface will cause the tanker's speed to decrease. In order to ensure the tanker's sailing speed, the staff will start the multi-stage push control device 3 through the ultrasonic cleaning main control box 7. When the multi-stage push control device 3 is started, it will first push the contact end of the rotating conduction mechanism 4 to contact the rotating stable conduction shaft 1. The rotating conduction mechanism 4 can adaptively engage with the rotating stable conduction shaft 1, so that the rotating conduction mechanism 4 will rotate accordingly. When the rotating conduction mechanism 4 rotates, it will drive the ultrasonic device 5 to rotate synchronously. When the ultrasonic device 5 rotates, it will rub the cleaning device 6 The cleaning end will be inserted between the ultrasonic device 5 and the stable conduction shaft 1. The rotation of the ultrasonic device 5 and the stable conduction shaft 1 will rub against the cleaning end of the friction cleaning device 6, which can effectively ensure that the docking end of the ultrasonic device 5 and the stable conduction shaft 1 remains clean. After the docking area of ​​the ultrasonic device 5 and the stable conduction shaft 1 is cleaned, the friction cleaning device 6 will be reset, and the multi-stage pushing control device 3 will continue to push. When the multi-stage pushing control device 3 continues to push, it will drive the rotating ultrasonic device 5 to collide with the stable conduction shaft 1. After the ultrasonic device 5 conflicts with the stable conduction shaft 1, the ultrasonic device 5 will emit ultrasonic waves to the stable conduction shaft 1, and the stable conduction shaft 1 will stably transmit the emitted ultrasonic waves to the rotating propeller 9. When the ultrasonic wave is emitted from the propeller 9 and contacts with seawater, it will generate bubbles. The shock wave generated by the bursting of the bubbles can achieve the effect of cleaning and flushing the inner and outer surfaces of the workpiece. On the one hand, ultrasonic waves destroy dirt and adsorbents on the surface of the cleaning parts, and on the other hand, they can cause the dirt layer to be peeled off due to fatigue damage. The vibration of gas bubbles scrubs the solid surface. Once there is a gap in the dirt layer to drill, the bubbles immediately drill in and vibrate to make the dirt layer fall off. The system is easy to operate, has low maintenance costs, and a high degree of automation. It can effectively solve the problem of biological adhesion on the surface of the propeller 9, reducing the number of times the ship enters the dock and shortening the time for replacing and repairing the blades, thereby shortening the overall repair cycle of the ship and reducing costs.
