Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 9As shown, the technical solution adopted by the present invention is as follows: a cleaning device for tank washing of an oil tanker comprises a nozzle 25, a guide mechanism and a drive assembly.

[0030] A slide bar 6 is fixedly installed in the cabin, and a limit block 7 is provided on the slide bar 6. A lead screw 1 is rotatably installed in the cabin, and the lead screw 1 is parallel to the slide bar 6. A first motor 2 is fixedly installed in the cabin, and the first motor 2 is coaxially fixedly connected to the lead screw 1. The lead screw 1 is threadedly connected to a slider 3.

[0031] The guide mechanism is connected between the slide block 3 and the limit block 7. Under the action of the lead screw 1, the guide mechanism moves along the slide rod 6.

[0032] A moving frame 10 is slidably connected to the guide mechanism. Fixed rods 9 are provided on both sides of the moving frame 10. Two rollers 8 are rotatably mounted on the upper end of each fixed rod 9, and the guide mechanism is clamped between the two rollers 8 on the same fixed rod 9. The moving frame 10 is mounted on the guide mechanism through the rollers 8. When the moving frame 10 moves forward along the guide mechanism, the rollers 8 rotate. The side surface of the guide mechanism that cooperates with the rollers 8 is an arc surface.

[0033] A first rotating shaft 11 is rotatably mounted in the moving frame 10, and a rotating plate 12 is fixedly connected to the first rotating shaft 11. A mounting block 23 is mounted at the lower end of the rotating plate 12, and a bellows 24 is mounted at the lower end of the mounting block 23. A nozzle 25 is mounted at the lower end of the bellows 24 and the nozzle 25 is connected to the bellows 24. A connecting pipe 27 is mounted on the bellows 24, and the connecting pipe 27 is connected to an external water supply device.

[0034] A driving assembly is installed on the movable frame 10. Under the action of the driving assembly, the rotating plate 12 and the nozzle 25 swing around the first rotating shaft 11, so that the spraying range of the nozzle 25 is expanded, and at the same time, the bellows 24 is bent and deformed, thereby changing the spraying angle of the nozzle 25 and further expanding the spraying range of the nozzle 25.

[0035] The driving assembly includes a second gear 14, a fifth gear 21 and a first gear 13. A second motor is fixedly mounted on the rotating plate 12, and a motor shaft of the second motor is coaxially fixedly connected to the second gear 14. The first gear 13 is coaxially fixedly connected to the first rotating shaft 11, and the first gear 13 is meshed with the second gear 14. The second motor drives the rotating plate 12 to rotate around the first rotating shaft 11 through the second gear 14 and the first gear 13. By controlling the forward and reverse rotation of the second motor, the rotating plate 12 is swung to expand the spraying range of the nozzle 25.

[0036] A fixed plate 19 is fixedly mounted on the rotating plate 12, and second rotating shafts 20 are rotatably mounted on both ends of the fixed plate 19. A fifth gear 21 is coaxially fixedly connected to each second rotating shaft 20. The two fifth gears 21 are respectively arranged on both sides of the second gear 14, and the two fifth gears 21 are both meshed with the second gear 14.

[0037] A winding wheel 22 is fixedly sleeved on each second rotating shaft 20. A through hole is provided on the mounting block 23 at a position corresponding to the winding wheel 22. A pull rope 26 is wound around each winding wheel 22, and the free end of the pull rope 26 passes through the corresponding through hole and is fixedly connected to the nozzle 25.

[0038] When the second gear 14 rotates, the fifth gear 21 rotates simultaneously, one winding wheel 22 reels the line, and the other winding wheel 22 releases the line, thereby causing the bellows 24 to bend and deform to one side, and the bellows 24 drives the nozzle 25 to move, thereby expanding the spraying range of the nozzle 25.

[0039] The guide mechanism includes a first guide plate 4 and a second guide plate 5. One end of the first guide plate 4 and the second guide plate 5 are fixedly connected to the slider 3, and the other ends of the first guide plate 4 and the second guide plate 5 are fixedly connected to the limit block 7. Corrugated grooves are provided on the opposite sides of the first guide plate 4 and the second guide plate 5.

[0040] Each corrugated groove includes a plurality of first guide segments 28 and a plurality of second guide segments 2801. On the same corrugated groove, the plurality of first guide segments 28 are parallel to each other, and the end of the first guide segment 28 close to the slider 3 is inclined in the direction away from another corrugated groove. The plurality of second guide segments 2801 are parallel to each other, and the end of the second guide segment 2801 close to the slider 3 is inclined in the direction close to another corrugated groove, and the first guide segment 28 and the second guide segment 2801 are connected in this way.

[0041] A push plate 16 is rotatably mounted on the rotating plate 12. A third motor 17 is fixedly mounted on one side of the rotating plate 12, and a fourth gear 18 is coaxially fixedly connected to the motor shaft of the third motor 17. A rotating rod is rotatably mounted on the rotating plate 12, and the push plate 16 is fixedly mounted on the rotating rod. A third gear 15 is coaxially fixedly mounted on the rotating rod, and the third gear 15 meshes with the push plate 16.

[0042] The push plate 16 has a diamond-shaped cross section and is provided with two arcuate surfaces 161, one of which cooperates with the corrugated groove on the first guide plate 4, and the other arcuate surface 161 cooperates with the corrugated groove on the second guide plate 5. The two arcuate surfaces 161 are respectively provided on two adjacent side surfaces of the push plate 16 and are located at one end away from the two side surfaces.

[0043] The push plate 16 is located between the first guide plate 4 and the second guide plate 5. The push plate 16 swings synchronously with the rotating plate 12. When the push plate 16 swings toward the direction close to the first guide plate 4, the push plate 16 contacts the side wall of the corrugated groove on the first guide plate 4, and under the guidance of the corrugated groove, the push plate 16 moves forward, and the push plate 16 drives the rotating plate 12 to move forward. When the push plate 16 swings toward the other side, that is, when the push plate 16 swings toward the direction close to the second guide plate 5, the push plate 16 contacts the side wall of the corrugated groove on the second guide plate 5, and under the guidance of the corrugated groove on the second guide plate 5, the push plate 16 moves forward. As the push plate 16 swings, under the action of the guide mechanism, the push plate 16 moves forward, and the nozzle 25 moves forward.

[0044] Working principle: Initially, one of the arcuate surfaces 161 cooperates with the first guide segment 28 on the first guide plate 4 , and the other arcuate surface 161 cooperates with the first guide segment 28 on the second guide plate 5 .

[0045] The first motor 2 is started to move the guide mechanism along the slide bar 6 to adjust the position of the nozzle 25 in the cabin. After that, the connecting pipe 27 is connected to the water supply device, and the water supply device transports clean water into the pull rope 26 and sprays it out through the nozzle 25 to clean the cabin.

[0046] The second motor is started, and the second motor drives the rotating plate 12 to rotate. By controlling the forward and reverse rotation of the second motor, the rotating plate 12 is swung around the first rotating shaft 11, the spraying range of the spray head 25 is expanded, and the cabin is fully cleaned.

[0047] At the same time, the second gear 14 drives the fifth gear 21 to rotate. Figure 3 As shown, when the rotating plate 12 swings to the right, the reel 22 on the right side of the second gear 14 reels in the wire, the reel 22 on the left side pays out the wire, and the right side of the nozzle 25 moves upward, causing the bellows 24 to bend and deform to the right. When the rotating plate 12 swings to the left, the reel 22 on the left side of the second gear 14 reels in the wire, the reel 22 on the right side pays out the wire, and the bellows 24 bends and deforms to the left. As the rotating plate 12 swings, the bellows 24 bends and deforms, further expanding the spraying range of the nozzle 25.

[0048] When the rotating plate 12 swings, the push plate 16 swings synchronously. When the push plate 16 swings toward the direction close to the first guide plate 4, after the push plate 16 contacts the side wall of the first guide section 28 on the first guide plate 4, under the guiding action of the first guide section 28 on the first guide plate 4, the push plate 16 moves forward along the first guide plate 4. When the push plate 16 moves to the intersection of the first guide section 28 and the second guide section 2801 on the first guide plate 4, the push plate 16 starts to swing toward the direction close to the second guide plate 5, and the arcuate surface 161 of the push plate 16 close to the second guide plate 5 is opposite to the first guide section 28 on the second guide plate 5. After the push plate 16 contacts the side wall of the first guide section 28 on the second guide plate 5, under the guiding action of the first guide section 28 on the second guide plate 5, the push plate 16 moves forward along the second guide plate 5. Accordingly, during the swinging process of the push plate 16, it moves forward at the same time under the guiding action of the first guide sections 28 of the corrugated grooves on both sides. The push plate 16 drives the rotating plate 12 to move forward, and the nozzle 25 moves forward, so that the nozzle 25 cleans the cabin more thoroughly.

[0049] When the push plate 16 moves to one end of the guide mechanism, the third motor 17 is started, and the third motor 17 rotates the push plate 16 180 degrees through the fourth gear 18 and the third gear 15, so that one of the arcuate surfaces 161 cooperates with the second guide segment 2801 on the first guide plate 4, and the other arcuate surface 161 cooperates with the second guide segment 2801 on the second guide plate 5. In this way, when the push plate 16 swings, under the action of the second guide segment 2801, the push plate 16, the rotating plate 12 and the nozzle 25 move to the other end of the guide mechanism.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
