At the same time, the contact between the cleaning roller brush and the hull is controlled by the cylinder 3, and the contact force between the cleaning roller brush and the hull cannot be accurately controlled, resulting in low cleaning efficiency of the hull. The cylinder 3 is rotated to drive the adjustment unit 4 to move, so that the guide unit 5, the extrusion unit 6 and the mounting rod 7 move accordingly, and the height of the cleaning roller brush on the mounting rod 7 is adjusted;

[0034] When the cleaning roller brush contacts and squeezes the hull, it pushes the connecting wall 601 and the sliding seat 602 to move upward. At this time, the sliding seat 602 slides along the outer wall of the threaded rod 603, so that the spring 604 is compressed between the sliding seat 602 and the adjusting nut 605. Under the rebound of the spring 604, the cleaning roller brush is pushed to contact and squeeze the hull, thereby increasing the cleaning force on the hull.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] The embodiment of the invention discloses a hull surface cleaning robot.

[0037] According to the attached Figure 1-7 As shown, it includes a cleaning robot 1, a lifting unit 2, a cylinder 3, an adjusting unit 4, a guide unit 5 and an extrusion unit 6, the lifting unit 2 is arranged on the cleaning robot 1, the cylinder 3 is installed on the lifting unit 2, the output end of the cylinder 3 is connected to the adjusting unit 4, the guide unit 5 is arranged on the outer wall of the guide unit 5, and the extrusion unit 6 is arranged on the adjusting unit 4;

[0038] In particular, the lifting unit 2 includes an adjusting seat 202, which is slidably connected to the cleaning robot 1. A rotating rod 203 is rotatably connected between the adjusting seat 202 and the cylinder 3. The adjusting seat 202 is driven to move by a driving mechanism. Under the movement of the adjusting seat 202, the rotating rod 203 is pushed to rotate. Under the push of the rotating rod 203, the cylinder 3 is rotated on the fixed seat 201. Under the rotation of the cylinder 3, the adjusting unit 4 is driven to move, so that the guide unit 5, the squeezing unit 6 and the mounting rod 7 are moved accordingly, and the height of the cleaning roller brush on the mounting rod 7 is adjusted;

[0039] It should be particularly emphasized that the adjustment unit 4 includes a connecting rod 401 and a connecting seat 405. The connecting rod 401 is located between the cylinder 3 and the connecting seat 405. When one of the cylinders 3 is started to move, the upper rotating seat 402 is driven to move, and the connecting rod 401 is pulled to rotate, so that the lower rotating seat 403 rotates relative to the rotating block 404. At this time, the rotating block 404 drives the connecting seat 405 to rotate, and drives the extrusion unit 6 and the mounting rod 7 to rotate, so as to adjust the position of the cleaning roller brush to be tilted, so as to facilitate the cleaning of the inclined objects on the hull, meet the cleaning of the inclined surface on the hull, and be suitable for cleaning different surfaces of the hull.

[0040] The guide unit 5 includes a connecting plate 501, which is rotatably connected to the connecting seat 405. The connecting plate 501 is slidably connected to the outer wall of the cleaning robot 1. When the cylinder 3 rotates on the fixed seat 201, the adjustment unit 4 moves upward, so that the connecting seat 405 moves upward. At this time, the connecting seat 405 drives the connecting plate 501 and the sliding block 503 to slide along the guide track 502, so that the movement of the connecting seat 405 relative to the cleaning robot 1 is relatively stable;

[0041] It should be particularly emphasized that the extrusion unit 6 includes a connecting wall 601 and a sliding seat 602, the connecting wall 601 is fixedly connected to the sliding seat 602, and the sliding seat 602 is located above the connecting seat 405. When the cleaning roller brush contacts and squeezes the hull, the connecting wall 601 and the sliding seat 602 are pushed to move upward. At this time, the sliding seat 602 slides along the outer peripheral wall of the threaded rod 603, so that the spring 604 is compressed between the sliding seat 602 and the adjusting nut 605. Under the rebound of the spring 604, the cleaning roller brush is pushed to contact and squeeze the hull, thereby improving the cleaning force on the hull.

[0042] It is particularly disclosed that a mounting rod 7 is rotatably connected between the connecting walls 601, and a cleaning roller brush is sleeved on the mounting rod 7. The driving mechanism drives the transmission wheel 701 and the mounting rod 7 to rotate, so that the cleaning roller brush rotates, and the hull is cleaned under the action of the cleaning roller brush.

[0043] Furthermore, a fixed base 201 is fixedly connected to the cleaning robot 1, and the cylinder 3 is rotatably connected to the fixed base 201. A driving mechanism is fixedly connected to one end of the adjusting base 202, and the adjusting base 202 is driven to move by the driving mechanism. When the adjusting base 202 moves, the rotating rod 203 is pushed to rotate. When the rotating rod 203 is pushed, the cylinder 3 is rotated on the fixed base 201. When the cylinder 3 rotates, the adjusting unit 4 is driven to move, so that the guide unit 5, the extrusion unit 6 and the mounting rod 7 move accordingly, and the height of the cleaning roller brush on the mounting rod 7 is adjusted.

[0044] Furthermore, an upper rotating seat 402 is fixedly connected to the output end of the cylinder 3 , and the upper rotating seat 402 is rotatably connected to the connecting rod 401 , and the other end of the connecting rod 401 is rotatably connected to the lower rotating seat 403 .

[0045] A rotating block 404 is rotatably connected to the inner wall of the lower rotating seat 403, and the rotating block 404 is slidably connected to the top end surface of the connecting seat 405. When one of the cylinders 3 is started to move, the cylinder 3 drives the upper rotating seat 402 to move. Under the movement of the upper rotating seat 402, the connecting rod 401 is pulled to rotate, and the connecting rod 401 rotates along the lower rotating seat 403.

[0046] Since the position of the connecting seat 405 relative to the cleaning robot 1 is limited, the lower rotating seat 403 rotates relative to the rotating block 404, and the rotating block 404 slides on the connecting seat 405. At this time, the rotating block 404 drives the connecting seat 405 to rotate, and drives the extrusion unit 6 and the mounting rod 7 to rotate, so as to adjust the position of the cleaning roller brush to be tilted, which is convenient for cleaning inclined objects on the hull and meets the cleaning requirements of the inclined surface of the hull, and is suitable for cleaning different surfaces of the hull.

[0047] A guide track 502 is fixedly connected to the outer wall of the cleaning robot 1, and a sliding block 503 is slidably connected to the inner wall of the guide track 502. The sliding block 503 is rotatably connected to the connecting plate 501. When the connecting seat 405 moves, the connecting seat 405 drives the connecting plate 501 to rotate, so that the connecting plate 501 rotates relative to the sliding block 503, so that the sliding block 503 slides on the inner wall of the guide track 502; when the cylinder 3 rotates on the fixed seat 201, the adjusting unit 4 moves upward, so that the connecting seat 405 moves upward. At this time, the connecting seat 405 drives the connecting plate 501 and the sliding block 503 to slide along the guide track 502, so that the movement of the connecting seat 405 relative to the cleaning robot 1 is relatively stable.

[0048] A threaded rod 603 is fixedly connected to the top end surface of the connecting seat 405 , and an adjusting nut 605 is threadedly connected to the outer peripheral wall of the threaded rod 603 .

[0049] The bottom end surface of the adjusting nut 605 is rotatably connected to a contact block 606, and the bottom of the contact block 606 is fixedly connected to a spring 604, and the other end of the spring 604 is fixedly connected to the sliding seat 602. When the cleaning roller brush contacts and squeezes the hull, the connecting wall 601 and the sliding seat 602 are pushed to move upward. At this time, the sliding seat 602 slides along the outer peripheral wall of the threaded rod 603, so that the spring 604 is compressed between the sliding seat 602 and the adjusting nut 605. Under the rebound of the spring 604, the cleaning roller brush is pushed to contact and squeeze the hull, thereby improving the cleaning force on the hull; by rotating the adjusting nut 605 to rotate along the threaded rod 603, the adjusting nut 605 drives the contact block 606 to move, so that the contact block 606 compresses the spring 604, changes the thrust of the spring 604 on the sliding seat 602, and then changes the contact force between the cleaning roller brush and the hull, thereby improving the cleaning force on the hull.

[0050] A transmission wheel 701 is sleeved on the outer peripheral wall of the mounting rod 7, and the transmission wheel 701 is connected to the driving mechanism through a transmission belt.

[0051] Working principle: by moving the cleaning robot 1 to the position on the hull that needs to be cleaned, the cleaning roller brush is adjusted to move, and the adjusting seat 202 is driven to move by the driving mechanism. Under the movement of the adjusting seat 202, the rotating rod 203 is pushed to rotate. Under the push of the rotating rod 203, the cylinder 3 is rotated on the fixed seat 201. Under the rotation of the cylinder 3, the adjusting unit 4 is driven to move, so that the guide unit 5, the squeezing unit 6 and the mounting rod 7 are moved accordingly, and the height of the cleaning roller brush on the mounting rod 7 is adjusted;

[0052] When the adjusting unit 4 moves upward, the connecting seat 405 moves upward. At this time, the connecting seat 405 drives the connecting plate 501 and the sliding block 503 to slide along the guide track 502, so that the connecting seat 405 moves relative to the cleaning robot 1;

[0053] When one of the cylinders 3 is started to move, the cylinder 3 drives the upper rotating seat 402 to move, and under the movement of the upper rotating seat 402, the connecting rod 401 is pulled to rotate, and the connecting rod 401 rotates along the lower rotating seat 403;

[0054] At this time, the rotating block 404 drives the connecting seat 405 to rotate, drives the extrusion unit 6 and the mounting rod 7 to rotate, and adjusts the position of the cleaning roller brush to be tilted, so as to facilitate the cleaning of inclined objects on the hull and meet the cleaning requirements of the inclined surface of the hull, and is suitable for cleaning different surfaces of the hull.

[0055] When the cleaning roller brush contacts and squeezes the hull, the connecting wall 601 and the sliding seat 602 are pushed upward, and the sliding seat 602 slides along the outer peripheral wall of the threaded rod 603, so that the spring 604 is compressed between the sliding seat 602 and the adjusting nut 605. Under the rebound of the spring 604, the cleaning roller brush is pushed to contact and squeeze the hull, thereby improving the cleaning force on the hull;

[0056] The driving mechanism drives the transmission wheel 701 and the mounting rod 7 to rotate, so that the cleaning roller brush rotates. Under the action of the cleaning roller brush, the hull is cleaned, and the hull is cleaned in cooperation with the high-pressure water gun on the cleaning robot 1.
