[0040] The adaptive adjustment component includes a slide rail frame 15 fixedly mounted inside the robot housing 1, and the slide rail frame 15 is on the symmetrical plane of the first arc rod 6 and the second arc rod 7. The interior of the slide rail frame 15 is equipped with a first slide plate 16 and a second slide plate 17 for sliding up and down, and the second slide plate 17 is located above the first slide plate 16. The second slide plate 17 and the first slide plate 16 are respectively rotatably provided with a second optical axis 20 and a first optical axis 19. The outer surfaces of the first optical axis 19, the second optical axis 20, the third optical axis 21 and the fourth optical axis 22 are all fixedly sleeved with a transmission wheel 25, and the external transmission of the four transmission wheels 25 is equipped with a transmission chain 26. The second slide plate 17 is away from the second optical axis 2 0 is fixedly mounted with a second motor 18 at one end surface, and the output end of the second motor 18 is used to drive the second optical axis 20 to rotate, a first connecting arm 23 is hingedly assembled between the second optical axis 20 and the third optical axis 21 and the fourth optical axis 22, a second connecting arm 24 is hingedly assembled between the first optical axis 19 and the third optical axis 21 and the fourth optical axis 22, and an elastic tightening component is also arranged between the third optical axis 21 and the fourth optical axis 22. Through the restriction of the second optical axis 20 and the first optical axis 19 by the slide rail frame 15 and the action of the elastic tightening component, when the distance between the first optical axis 19 and the second optical axis 20 is shortened, the distance between the third optical axis 21 and the fourth optical axis 22 will increase, and vice versa.

[0041] The elastic tightening assembly includes two straight groove swing arms 27 distributed in an interlaced and opposite manner inside the triangular frame plate 12. The bottoms of the two straight groove swing arms 27 are both rotatably sleeved on the outer surface of the second rotating shaft 9, and the tops of the two straight groove swing arms 27 are respectively rotatably sleeved on the outer surfaces of the third optical axis 21 and the fourth optical axis 22.

A tension spring 31 is also fixedly arranged between the bottom of the limit plate 30 and the robot shell 1, and the tension spring 31 is distributed on the outside of the positioning rod 29. Under the elastic pulling of the tension spring 31, the limit plate 30 can slide downward, wherein the positioning rod 29 limits the limit plate 30 to slide only in the vertical direction, and cannot rotate left and right. The up and down movement of the limit plate 30, combined with the restriction of the connecting rod 32, can open or merge the two straight groove swing arms 27. When the two straight groove swing arms 27 are opened, the first arc rod 6 and the second arc rod 7 can extend outside the robot shell 1, so that the positions of the third rotating shaft 10 and the fourth rotating shaft 11 change.

[0042] The elastic tension of the tension spring 31 is smaller than the magnetic attraction between the magnetic tracks 13 and the hull, that is, the elastic force generated by the tension spring 31 can only change the position of the first arc rod 6 and the second arc rod 7 when the magnetic tracks 13 are not magnetically attracted to the hull, so the tension spring 31 will not affect the stability of the magnetic attraction between the magnetic tracks 13 and the hull.

[0043] The two side walls of each magnetic track 13 are fitted with protective plates 14, and the protective plates 14 are rotatably mounted on the outside of the first rotating shaft 8, the second rotating shaft 9, the third rotating shaft 10 and the fourth rotating shaft 11. The protective plates 14 are made of non-magnetic hard material. The protective plates 14 can protect both sides of the magnetic track 13 to prevent floating objects in the sea water from entering between the magnetic track 13 and the track wheel, thereby ensuring the stability of the transmission of the magnetic track 13.

[0044] Example 2: Please refer to the attached Figure 3-Figure 6 This embodiment is a further explanation of the above-mentioned embodiment 1. The anti-blocking unit includes a docking tube 28 fixedly arranged inside the robot shell 1, and the docking tube 28 is located on the side of the robot shell 1 away from the external frame 2. The side of the docking tube 28 away from the external frame 2 is open, and the other end is closed. The input end of the suction pump 4 is fixedly connected and docked with the closed port of the docking tube 28. The open port of the docking tube 28 is provided with a rotating cutting component, and the outside of the robot shell 1 is also provided with a trigger component for driving the rotating cutting component. The trigger component can follow the second motor 18 to run and drive the rotating cutting component to rotate, so as to shred the floating objects that are about to enter the docking tube 28.

[0045] The trigger component includes an extension plate fixedly arranged on the top of one of the straight groove swing arms 27, and a first sealing cylinder 34 is fixedly mounted on the extension plate, a first piston 35 is slidably mounted inside the first sealing cylinder 34, and a first piston rod 36 that slides through the first sealing cylinder 34 is fixedly arranged inside the first piston 35, an eccentric wheel 33 is also fixedly sleeved on the outer surface of the third optical axis 21 or the fourth optical axis 22, and the eccentric wheel 33 slides and fits with the exposed end of the first piston rod 36, a second sealing cylinder 37 is fixedly mounted on the outer wall of the robot housing 1, and a second piston 38 is slidably mounted inside the second sealing cylinder 37, a second piston rod 39 that slides through the second sealing cylinder 37 is fixedly arranged at the bottom of the second piston 38, and the second piston rod 39 that slides through the second sealing cylinder 37 is fixedly arranged at the bottom of the second piston 38. A limit plate 40 is also fixedly provided at the bottom of the plug rod 39, a spring 41 is provided between the lower end surface of the second piston 38 and the second sealing cylinder 37, and the spring 41 is distributed on the outside of the second piston rod 39, and a delivery pipe is provided at the top of the second sealing cylinder 37 and connected to the end of the first sealing cylinder 34 away from the first piston rod 36, and the delivery pipe is fixedly passed through the robot housing 1, and the lower end surface of the first piston rod 36 extends out of the first sealing cylinder 34. When the eccentric wheel 33 rotates and pushes the first piston 35 upward through the first piston rod 36, the medium inside the first sealing cylinder 34 can be transferred to the inside of the second sealing cylinder 37 through the delivery pipe, and the second piston 38 is pushed downward, so that the second piston rod 39 moves downward with the limit plate 40.

[0046] The rotating cutting component includes a fixed cutting disc 43 covering the open end of the docking tube 28, and the fixed cutting disc 43 is fixedly assembled with the robot shell 1, and the end surface of the fixed cutting disc 43 away from the robot shell 1 is also coaxially rotatably provided with a movable cutting disc 44, and the fixed cutting disc 43 and the movable cutting disc 44 are slidably fitted, and a plurality of cutting notches 45 equidistantly distributed around the circumference are provided inside the fixed cutting disc 43 and the movable cutting disc 44, and the inclination directions of the two groups of cutting notches 45 are opposite, and the cutting edges of the two groups of cutting notches 45 are distributed facing each other, and a plurality of fixed ratchets equidistantly distributed around the circumference are fixedly provided on the outer surface of the movable cutting disc 44, and the inner elastic rotation of the limit plate 40 is equipped with a plurality of There are a plurality of movable ratchets 42 equidistantly distributed in a straight line, and the movable ratchets 42 are movably engaged with the fixed ratchets. When the limit plate 40 moves downward with the movable ratchets 42, the movable ratchets 42 can engage with the fixed ratchets, thereby allowing the movable cutting disk 44 to rotate. When the limit plate 40 moves upward with the movable ratchets 42, the movable ratchets 42 can elastically shrink to the inside of the limit plate 40 due to the restriction of the fixed ratchets. Therefore, impurities that float into the docking tube 28, such as kelp, fishing line, etc., will be chopped up before entering the docking tube 28. The chopped floating objects will not cause blockage to the input end of the suction pump 4, and the suction pump 4 can directly suck the fine impurities and then spray them out.

[0047] Working principle: When the robot is not attached to the surface of the ship, the state of the magnetic track 13 at the bottom is the same as that of the robot attached to the ship. Fig.11 In the state in which the robot is placed outside the hull, the magnetic attraction force exerted by the plurality of magnetic tracks 13 on the hull can flatten the plurality of magnetic tracks 13, and the tension spring 31 will be stretched open under the action of the magnetic force;

[0048] The staff adjusts the walking angle of the robot and drives the second motor 18. The second motor 18 drives the third optical axis 21 and the fourth optical axis 22 to rotate synchronously in the same direction, so that the third rotating shaft 10 and the fourth rotating shaft 11 at the bottom of the first arc rod 6 and the second arc rod 7 rotate, so that the multiple magnetic tracks 13 can rotate synchronously in the same direction. When the robot walks to the connection between the side of the hull and the bottom of the hull, the curvature at this position is large, so when the robot moves with the attachment Figure 7 or attached Figure 8 When the magnetic track 13 distributed in the front is in magnetic contact with the bottom of the hull, the magnetic track 13 distributed in the rear is in contact with the side wall of the hull, and the magnetic track 13 distributed in the front and back will gradually become attached. Fig.11 In this state, the robot can walk with magnetic contact at multiple points by passing through the curved part, and the robot can ensure the stability of walking on the surface of the hull through adaptive adjustment. Compared with the crawler in the prior art that cannot change the angle, the magnetic crawler 13 in this solution has better walking stability;

[0049] Moreover, a protective plate 14 is slidably attached to the outer side of each magnetic track 13 to prevent floating objects in the seawater from getting stuck between the magnetic track 13 and the track wheel, thereby hindering the operation of the magnetic track 13 .

[0050] It should be noted that the staff can hang an anti-lost rope on the surface of the robot housing 1 to ensure that even if the robot falls off, it can be recovered to avoid losses.

[0051] During the traveling process, the first motor 3 and the suction pump 4 are driven, and the first motor 3 is used to drive the water spray pipe 5 to swing left and right, so that the nozzle at the end of the water spray pipe 5 cleans the barnacles on the surface of the hull in a fan-shaped arc, wherein the input end of the suction pump 4 sucks seawater through the docking tube 28, and then the pressure water is discharged through the water spray pipe 5 through the output end of the suction pump 4 after pressurization;
