DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present application in detail with reference to the drawings and embodiments.

[0021] As Figures 1 to 4As shown in the figure, the present application discloses a swing cleaning device, including a base 1, a first rotating motor 2, a swing assembly, a swing frame 3, a second rotating motor 4, a rotating assembly, a rotating frame 5 and a cleaning tank 6. The swing frame 3 is rotatably installed on the base 1 through a rotating shaft 24. One end of the swing assembly is connected to the output end of the first rotating motor 2, and the other end of the swing assembly is fixedly connected to the swing frame 3. The first rotating motor 2 drives the swing assembly to move up and down. The second rotating motor 4 is fixedly installed on the swing frame 3. The rotating assembly is connected to the output end of the second rotating motor 4. First rollers 29 are coaxially fixed at both ends of the rotating frame 5 respectively. The first rollers 29 are rotatably connected to the swing frame 3. The rotating assembly abuts against the first rollers 29. The cleaning tank 6 is fixedly installed inside the rotating frame 5. The first rotating motor 2 drives the swing frame 3 to swing up and down through the swing assembly. The rotating frame 5 swings up and down with the swing frame 3, so that the rotating frame 5 drives the cleaning tank 6 to swing up and down. The second rotating motor 4 drives the first rollers 29 to rotate through the rotating assembly, so that the first rollers 29 drive the rotating frame 5 to rotate. The rotating frame 5 drives the cleaning tank 6 to rotate synchronously, so that the cleaning tank 6 realizes up and down swinging and 360-degree rotation, and realizes 360-degree dead-angle-free full coverage cleaning of the inner cavity of the tank in a rotating and swinging manner.

[0022] As Figure 3 shown in the figure, the swing assembly includes a first transmission shaft 7, a first swing rod 8 and a second swing rod 9. The first rotating motor 2 is synchronously transmitted with the first transmission shaft 7. The first transmission shaft 7 is fixedly connected to one end of the first swing rod 8. The other end of the first swing rod 8 is hinged to the second swing rod 9. The second swing rod 9 is rotatably connected to the swing frame 3. The first rotating motor 2 can achieve synchronous transmission by being coaxially connected with the first transmission shaft 7. The first rotating motor 2 can also achieve synchronous transmission with the first transmission shaft 7 through the meshing of a first conical wheel (coaxially connected with the first rotating motor 2) and a second conical wheel (coaxially connected with the first transmission shaft 7). The first transmission shaft 7 drives the first swing rod 8 to rotate, so that the end of the first swing rod 8 away from the first transmission shaft 7 makes a circular motion around the first transmission shaft 7. Thus, the first swing rod 8 drives the second swing rod 9 to move up and down, so that the second swing rod 9 drives the swing frame 3 to perform a seesaw-like motion, triggering the wave scouring of the liquid material in the cleaning tank. The number of the first swing rods 8 and the first transmission rods is two respectively. The two first swing rods 8 are symmetrically arranged on both sides of the second swing rod 9. The first swing rods 8 are connected to the first transmission rods one by one. One of the first transmission rods is synchronously driven with the first rotating motor 2, and the other transmission rod is rotatably installed on the support bearing seat

[0023] As Figure 4As shown, the rotating assembly includes a support base 10, a second transmission shaft 11, a driving gear 12, a driven gear 13, and a second roller 14. The second rotating motor 4 is synchronously driven with the second transmission shaft 11. The driving gear 12 is coaxially provided on the outer peripheral wall of the second transmission shaft 11. The driving gear 12 meshes with the driven gear 13. The second roller 14 is coaxially fixed with the driven gear 13. The second roller 14 is rotatably installed on the support base 10. The second roller 14 is in frictional contact with the first roller 29. The number of driven gears 13 can be multiple. The multiple driven gears 13 are meshed in sequence. The driven gear 13 at the end is meshed with the second rotating motor 4. The driven gear 13 at the other end is coaxially fixed with the second roller 14. The second rotating motor 4 drives the driving gear 12 to rotate through the second transmission shaft 11. The driving gear 12 drives the second roller 14 to rotate by meshing with the driven gear 13. The second roller 14 drives the first roller 29 to rotate, so that the rotating frame 5 drives the cleaning tank 6 to rotate 360°.

[0024] As Figure 4 shown, the swing frame 3 is provided with a support plate 16 with a slide rail 15. The axis of the slide rail 15 is parallel to the axis of the second roller 14. One end of the support base 10 is rotatably installed with the second roller 14. The other end of the support base 10 is provided with a slider 17 slidably connected to the slide rail 15. The width of the first roller 29 is greater than the axial sliding stroke of the second roller 14. The slider 17 slides along the slide rail 15, which can buffer and relieve the axial impact formed by the water flow on the rotating frame 5 and the cleaning tank 6 during movement. The length of the slide rail 15 is greater than the sliding amplitude of the slider 17 or stoppers are respectively provided at both ends of the slide rail 15. The width of the first roller 29 is greater than the sliding amplitude of the second roller 14, ensuring that the second roller 14 always drives the first roller 29 to roll.

[0025] In this embodiment, as Figure 2 shown, the first roller 29 is installed on the swing frame 3 through a universal bearing 18. The first bearing seat 19 of the universal bearing 18 is installed on the swing frame 3. The ball of the universal bearing 18 is connected with a transmission rod. The free end of the transmission rod is elastically connected with the first roller 29 through a spring 21. The spring 21 is sleeved on the outer peripheral wall of the transmission rod. The first roller 29 is rotatably connected with the swing frame 3 through the universal bearing 18, and the axial movement of the rotating frame 5 is buffered through the spring 21.

[0026] In this embodiment, as Figure 2As shown in the figure, a second bearing block 22 is installed on the base 1. A connecting frame 23 is provided at the bottom of the swing frame 3. A rotating shaft 24 passes through the bearing block and is fixedly connected to the connecting frame 23. The middle of the connecting frame 23 is connected to the rotating shaft 24. Both ends of the connecting frame 23 extend upward to form swing arms 25. The end face of the swing arm away from the rotating shaft 24 is fixedly connected to the swing frame 3. The connecting frame 23 is arranged in a V shape, and the connecting frame 23 makes both ends of the swing frame 3 higher than the lowest point where the V-shaped frame is connected to the base 1, avoiding interference between the swing frame 3 and the base 1 during the up-and-down shaking process.

[0027] In this embodiment, angle members are provided at the bottom of the cleaning tank 6. The angle members are fixed to the rotating frame 5 by screws. A cross beam 20 is provided at the top of the rotating frame 5. The cross beam 20 abuts against the top of the cleaning tank 6 through a compression bolt. The angle member can be an L-shaped connecting member. The cleaning tank 6 is fixed inside the rotating frame 5 by screws and compression bolts.

[0028] As Figure 4 shown, in this embodiment, there are two sets of passive gears 13. The number of the second rollers 14 is two. The two sets of passive gears 13 are respectively meshed with the active gear 12. The two second rollers 14 are connected to the two sets of passive gears 13 in one-to-one correspondence, and the two second rollers 14 are distributed along the circumference of the first roller 29. The two second rollers 14 jointly drive the first roller 29, improving the efficiency.

[0029] As Figure 4 shown, a rotating assembly is installed at one end of the support plate 16, and an auxiliary assembly is installed at the other end of the support plate 16. The auxiliary assembly includes a first support plate 26 and a second support plate 27 rotatably connected to the first support plate 26. A plurality of auxiliary wheels 28 are rotatably provided on the second support plate 27. The plurality of auxiliary wheels 28 are distributed along the circumferential direction of the first roller 29, and the auxiliary wheels 28 are in rolling contact with the first roller 29. The auxiliary wheels 28 support the first roller 29, making the rotation of the rotating frame 5 more stable.

[0030] In this embodiment, a controller, a displacement sensor, and an angle sensor are further included. The displacement sensor is arranged between the swing frame 3 and the base 1, and the angle sensor is arranged between the rotating frame 5 and the swing frame 3. The displacement sensor is used to detect the moving distance of the swing frame 3, and the angle sensor is used to detect the rotation angle of the rotating frame 5. The controller is electrically connected to the first rotating motor 2, the second rotating motor 4, the displacement sensor, and the angle sensor respectively. The controller controls the swing range of the swing frame 3 driven by the first rotating motor 2 through the feedback of the displacement sensor, and controls the rotation range of the rotating frame 5 driven by the second rotating motor 4 through the feedback of the angle sensor.
