One side of the fixed body 11 is welded with a fixed box 12, the inside of the fixed box 12 is provided with a transmission mechanism, and one side of the fixed box 12 is provided with two Two second through holes, the fixed box 12 is provided with a rotating shaft 19 at the two second through holes, one end of the rotating shaft 19 is welded with a rotating body 14, the outer wall of the rotating body 14 is rotatably connected with a fixed shaft 22, a fixed shaft 22 There is a rotating plate 13 on one end of the main body 1, and the main body 1 can walk on the ground by rollers. Through the connection of the first connecting rod 7 and the second connecting rod 8, the support column 6 is parallel to the fixed body 11, and the water inside the water storage tank 2 enters the two The water surface in the first through hole is on the same horizontal plane. When the main body 1 walks on the inclined ground, the water in the two first through holes moves the sealing plate 17 and makes the two sealing The plate is on the same horizontal plane, and then supported by the moving rod 16, the rotating plate 3 is rotated and is horizontal. At this time, the supporting column 6 is vertical, and the fixed body 11 is also vertical, so that the two rotating bodies The rotating plate 13 on 14 keeps the wall vertical through the transmission mechanism during the rotating and wiping process.
[0029] In the present invention, a rubber gasket is bonded to the bottom end of the sealing plate 17 to prevent the water in the water storage tank 2 from flowing out.
[0030] Wherein, one side of the support column 6 is welded with a fixing seat, the top of the fixing seat is fixedly connected with the first motor 5 by bolts, the output shaft of the first motor 5 is connected with a pulley through a key, and the outside of the pulley is bonded with a rigid wire 4 , The other end of the rigid wire 4 is bonded to the second connecting rod 8. The first motor 5 can be activated to cause the pulley to drive the rigid wire 4 to contract, and the second connecting rod 8 can be pulled to rotate the second connecting rod 8. 8 drives the fixed body 11 close to the support column 6. At this time, the height of the fixed body 11 rises, and the high wall can be polished by the rotating plate 13. When the first motor 5, the fixed body 11 automatically descends due to gravity. The two connecting rods 8 drive the fixed body 11 away from the support column 6 until the rotating plate 13 contacts the wall. At this time, the rotating plate 13 can be used to polish the low wall.
[0031] Wherein, the transmission mechanism includes a second motor 10, a first pulley 15, a second pulley 18, two belts 20 and a rotating shaft 21, a square through hole is opened in the middle of the fixed body 11, and the second motor 10 is in the square through hole. The inside of the fixed body 11 is fixedly connected by bolts. One side of the fixed box 12 is provided with a circular through hole. The output shaft of the second motor 10 extends to the inside of the fixed box 12 through the circular through hole. The output shaft of the second electric motor 10 is welded, and the outside of the rotating shaft 21 and the rotating shaft 19 are respectively fixedly connected with the first pulley 15 and the second pulley 18 by keys, and the two belts 20 are located outside the first pulley 15 and the second pulley 18 , Through the rotation of the second motor 10, the rotating shaft 21 can be driven to rotate, the rotating shaft 21 can drive the two second pulleys 18 to rotate through the first pulley 15 and the two belts 20, and the two second pulleys 18 drive the rotating shaft 19 to rotate , The rotating shaft 19 drives the rotating body 14 to rotate, so that the rotating plate 13 rotates, and the wall is polished.
[0032] Wherein, one side of the fixed body 11 is fixedly connected with a protective net 9 by screws. The protective net 9 is located on one side of the second motor 10. The protective net 9 can protect the second motor 10 and facilitate the heat dissipation of the second motor 10.
[0033] Among them, the rotating plate 13 is V-shaped, one end of the rotating plate 13 is welded with a fixed plate 23, one side of the fixed plate 23 is welded to the fixed shaft 22, and one side of the rotating plate 13 is provided with a number of bumps 24, which are hemispherical The other side of the rotating plate 13 is smooth. When the second motor 10 drives the rotating plate 13 to rotate counterclockwise, the smooth side of the rotating plate 13 touches the wall, and the wall can be finely ground by rotating with the rotating body 14. The fixed shaft 22 is connected to rotate the rotating plate 13 so that the side of the rotating plate 13 with the bump 24 contacts the wall, and the second motor 10 rotates clockwise, which can roughen the wall.
[0034] When in use, the main body 1 can walk on the ground by rollers. Through the connection of the first link 7 and the second link 8, the support column 6 is parallel to the fixed body 11, and the water inside the water storage tank 2 enters the two first through holes , The water surface in the first through hole is on the same horizontal plane. When the main body 1 is walking on the inclined ground, the water in the two first through holes moves the sealing plate 17 and makes the two sealing plates on the same horizontal plane. Then, the rotating plate 3 is rotated by the support of the moving rod 16 and becomes horizontal. At this time, the supporting column 6 is vertical, and the fixed body 11 is also vertical, so that the rotating plates on the two rotating bodies 14 13 Through the transmission mechanism, the wall is kept vertical during the rotation and polishing process;
[0035] The rotation of the second motor 10 can drive the rotating shaft 21 to rotate. The rotating shaft 21 can drive the two second pulleys 18 to rotate through the first pulley 15 and the two belts 20, and the two second pulleys 18 drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating body 14 to rotate, so that the rotating plate 13 rotates, and the wall is polished;
[0036] It is possible to start the first motor 5 to cause the pulley to drive the rigid line 4 to contract, pull the second link 8 to rotate the second link 8, and the second link 8 drives the fixed body 11 to approach the support column 6. When the height is raised, the high wall can be polished by the rotating plate 13. When the first motor 5, the fixed body 11 automatically descends due to gravity, and the second connecting rod 8 drives the fixed body 11 away from the supporting column 6 until the rotating plate 13 touch the wall, at this time you can use the rotating plate 13 to wipe the low wall;
[0037] When the second motor 10 drives the rotating plate 13 to rotate counterclockwise, the smooth side of the rotating plate 13 contacts the wall, and the wall can be finely ground. The fixed shaft 22 connected to the rotating body 14 can rotate the rotating plate 13 to make The side of the rotating plate 13 with the bump 24 contacts the wall, and the second motor 10 rotates clockwise, which can roughen the wall.
