Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and more particularly to a cleaning robot. Background Technology

[0002] With the development of technology, pipelines are receiving increasing attention as a long-distance transportation method for materials. Whether it is the drain pipes in household kitchens and bathrooms or the large-scale sewer systems in factories, hotels and commercial buildings, the use of pipelines can be seen everywhere. Pipelines are often used to transport fluids. When fluids flow in pipelines, foreign objects carried by the fluids will adhere to the inner walls of the pipelines, so the pipelines need to be cleaned regularly during use.

[0003] When cleaning long pipes, manual cleaning can only clear blockages, but cannot clean the inner walls. When cleaning the inner walls, only the inner walls at the openings can be cleaned. Even with tools of the appropriate length, the middle area of ​​the pipe is too long for manual cleaning because the tools are too difficult for the person to fully control. Summary of the Invention

This device can effectively and comprehensively clean the inner wall of a pipe, and the nozzle of the spray component can move with the cleaning head. Thus, when the cleaning head moves to contact the inner wall of the pipe, the nozzle of its spray component can also move to cooperate with it, thereby further improving the efficiency of the device in cleaning the pipe. Moreover, through the synergistic effect between multiple components, the device improves the quality of pipe cleaning at different angles.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0025] In the description of the invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] like Figure 1-5 As shown, the present invention proposes a cleaning robot comprising two spaced-apart fixed disks 1, with a mounting disk 2 coaxially disposed between the two fixed disks 1, and the mounting disk 2 rotatably connected to one of the fixed disks 1. One of the fixed disks 1 is provided with a mounting assembly for driving the mounting disk 2 to rotate. Multiple mounting rods 3 are evenly distributed around the circumference of one end of the mounting disk 2 facing the other fixed disk 1, and a cleaning head is provided at the end of each mounting rod 3 away from the mounting disk 2; the mounting rods 3 are rotatably connected to the mounting disk 2. The other fixed disk 1 is provided with a power assembly for driving the multiple mounting rods 3 to open or retract. Multiple moving assemblies are evenly distributed around the outer circumference of both fixed disks 1. A striking assembly is provided at the end of the other fixed disk 1 away from the mounting disk 2, and the striking assembly is drively connected to the driving assembly. A liquid spraying assembly is provided between the two fixed disks 1, and the spraying end of the liquid spraying assembly can move with the cleaning head.

[0028] This device, through its deployable mounting rod 3 structure, allows the cleaning head to fully contact the inner wall of the pipe. The rotation of the mounting plate 2 drives the cleaning head in a circular motion, working in conjunction with the spray component to achieve comprehensive cleaning. Furthermore, the deployment angle of the mounting rod 3 can be adjusted via a power component to accommodate different pipe diameters. The tapping component can tap the inner wall of the pipe before use, reducing the adhesion of dirt through pipe vibration. The moving component allows the device to move autonomously within the pipe, solving the problem of manual operation being difficult to penetrate long pipes. Therefore, this device can effectively and comprehensively clean the inner wall of the pipe. The spray component's nozzle can move with the cleaning head; when the cleaning head reaches contact with the inner wall of the pipe, the spray component's nozzle can also move to engage with it, further improving the device's cleaning efficiency. The spray component can spray a cleaning solution.

[0029] Furthermore, this application also proposes that it includes a first mounting bracket 7, a plurality of first mounting brackets 7 are evenly distributed around the end of the mounting plate 2 away from one of the fixed plates 1, one end of the mounting rod 3 is provided with a first through hole and extends into the first mounting bracket 7, a mounting shaft is rotatably provided inside the first mounting bracket 7, the mounting shaft passes through the first through hole and is connected to the mounting rod 3, a torsion spring is sleeved on the mounting shaft, one end of the torsion spring is connected to the mounting shaft, and the other end of the torsion spring is connected to the first mounting bracket 7.

[0030] Therefore, this technical solution achieves the rotation and automatic reset functions of the mounting rod 3 by setting up the first mounting bracket 7, the mounting shaft, and the torsion spring. The first mounting bracket 7 provides stable support and positioning for the mounting rod 3, the mounting shaft realizes the rotational connection of the mounting rod 3, and the torsion spring provides the reset force and prevents the mounting rod 3 from naturally becoming vertical under the action of gravity. This solution has a simple and reliable structure and can effectively solve the problem of the mounting rod 3 shifting due to uneven force during the cleaning process, thereby improving the positioning accuracy and cleaning effect of the cleaning head.

[0031] Furthermore, this application also proposes that the power assembly includes a guide plate 4, a drive cylinder 5, and a guide cylinder 6. The guide cylinder 6 is horizontally disposed between two fixed plates 1, and one end of the guide cylinder 6 is connected to another fixed plate 1. The drive cylinder 5 is slidably disposed on the guide cylinder 6. The guide plate 4 has a first opening for the drive cylinder 5 to pass through. The guide plate 4 is sleeved on the guide cylinder 6. The guide plate 4 is rotatably connected to the drive cylinder 5 and is coaxially disposed with the mounting plate 2. The outer circumferential surface of the guide plate 4 has a first notch that is equal in number to and corresponds one-to-one with a plurality of mounting rods 3. The mounting rods 3 can extend into the first notch corresponding to them and abut against the inner wall of the first notch. The other fixed plate 1 is provided with a drive unit for driving the guide plate 4 to move closer to or away from the mounting plate 2.

[0032] The first notch can be designed as a V-shaped or U-shaped structure to better fit with the mounting rod 3.

[0033] This technical solution achieves synchronous control of multiple mounting rods 3 through the cooperation of the guide plate 4 and the drive cylinder 5. When the drive unit pushes the guide plate 4 to move, the guide plate 4 drives the mounting rods 3 to rotate through the first notch. When the guide plate 4 approaches the mounting plate 2, the multiple mounting rods 3 unfold, thereby increasing the distance between the multiple mounting rods 3 and the mounting plate 2, so as to abut against the inner wall of the pipe. This design allows the cleaning head to adapt to the cleaning needs of the inner wall of pipes with different diameters, solving the problem that traditional tools are difficult to control precisely due to their excessive length.

[0034] Furthermore, this application also proposes that the drive unit includes a first electric telescopic cylinder 10, the fixed end of the first electric telescopic cylinder 10 is connected to another fixed plate, the telescopic rod of the first electric telescopic cylinder 10 is horizontally set, and the telescopic rod of the first electric telescopic cylinder 10 is connected to the drive cylinder 5.

[0035] Therefore, this technical solution can precisely control the axial displacement of the guide plate 4 by utilizing the linear drive characteristics of the electric telescopic cylinder, thereby adjusting the unfolding angle of the mounting rod 3.

[0036] Furthermore, this application also proposes a specific structure for the spraying assembly, which includes a second mounting bracket 12, a receiving tank 13, and a transmission plate 16. The second mounting bracket 12 is connected to the fixed plate 1. The receiving tank 13 is rotatably disposed within the second mounting bracket 12. The receiving tank 13 has a second opening and is equipped with an electric nozzle 14, the spraying end of which faces the cleaning head. A transmission ring 26 is slidably sleeved on the receiving tank 13, and a third mounting bracket 15 is provided on the transmission ring 26. The drive cylinder 5 is equipped with a transmission rod 27, and a fourth mounting bracket 17 is provided on the transmission rod 27. The two ends of the transmission plate 16 are rotatably connected to the third mounting bracket 15 and the fourth mounting bracket 17, respectively.

[0037] Therefore, when the drive cylinder 5 moves axially, it drives the fourth mounting bracket 17 to move. Since the transmission plate 16 is rotatably connected to the fourth mounting bracket 17, and the length of the transmission plate 16 cannot be changed, and because the other end of the transmission plate 16 is rotatably connected to the third mounting bracket 15, and the third mounting bracket 15 is connected to the transmission ring 26, the movement of the transmission plate 16 drives the transmission ring 26 to move on the receiving tank 13. The position and angle of the transmission ring 26 change due to the position of the third mounting bracket 15, ultimately changing the angle between the receiving tank 13 and the electric nozzle 14. Thus, when the mounting rod 3 is extended, the electric nozzle 14 can still face the cleaning head. The movement of the drive cylinder 5 also drives the guide plate 4 to move, thereby driving the mounting rod 3 to extend. Therefore, the position of the electric nozzle 14 moves synchronously with the cleaning head, ensuring that the cleaning fluid is accurately sprayed onto the cleaning area. This design solves the problems of cleaning fluid waste and uneven cleaning effect caused by fixed spray positions during pipeline cleaning.

[0038] Furthermore, this application also proposes that the drive assembly includes a motor 8 and a rotating shaft 9, wherein one of the fixed disks 1 is provided with a third opening, the motor 8 is fixedly installed in the third opening, the mounting disk 2 is provided with a second through hole, the other fixed disk 1 is provided with a third through hole, the rotating shaft 9 is rotatably installed in the third through hole, one end of the rotating shaft 9 passes through the second through hole and is coaxially connected to the output shaft of the motor 8, and the rotating shaft 9 passes through the drive cylinder 5 and is rotatably installed in contact with its inner wall.

[0039] Therefore, this technical solution uses motor 8 to drive rotating shaft 9, which in turn drives mounting plate 2 to rotate, thereby driving cleaning head and mounting rod 3.

[0040] Furthermore, this application also proposes that the striking assembly includes a cam 19, a mounting barrel 21, a moving rod 23, and a limiting block 24. The cam 19 is rotatably connected to the end of the fixed plate 1 away from the mounting plate 2. The cam 19 is coaxially connected to the rotating shaft 9. The limiting block 24 is located above the cam 19 and has a fourth through hole. The mounting barrel 21 is slidably disposed in the fourth through hole. The bottom end of the mounting barrel 21 is provided with a drive plate 20. The drive plate 20 is slidably disposed in contact with the outer peripheral surface of the cam 19. A first spring 22 is provided between the drive plate 20 and the limiting block 24. The first spring 22 is sleeved on the mounting barrel 21, and its two ends are respectively connected to the limiting block 24 and the drive plate 20. The moving rod 23 is slidably disposed in the mounting barrel 21. A second spring 28 is provided in the mounting barrel 21. The two ends of the second spring 28 are respectively connected to the inner wall of the mounting barrel 21 and the moving rod 23. The moving rod 23 can extend into the mounting barrel 21 and be fixed to the mounting barrel 21 through a fixing unit.

[0041] Therefore, this technical solution uses the cam 19 to drive the installation barrel 21 to move up and down, and with the elastic action of the spring, the moving rod 23 can periodically strike the inner wall of the pipe. With the action of the fixing unit, when the device is placed in the pipe, the moving rod 23 can be inserted into the installation barrel and fixed to it, thereby reducing its overall length and making it easier to put the device into the pipe.

[0042] Furthermore, this application also proposes a specific structure for the fixing unit. The fixing unit includes a bolt 25 and a locking block 29. A groove is provided on the inner wall of the mounting barrel 21, and the locking block 29 is slidably disposed in the groove and connected to the moving rod 23. The locking block 29 can be moved to abut against the inner wall of the groove. A first threaded through hole is provided on the outer circumferential surface of the mounting barrel 21, and a first blind hole is provided on the moving rod 23. The first blind hole can be moved to communicate with the first threaded through hole. The bolt 25 is threaded in the first threaded through hole, and one end of the bolt can extend into the first blind hole and abut against the inner wall of the first blind hole.

[0043] Thus, the fixing unit achieves the initial positioning of the moving rod 23 through the cooperation of the locking block 29 and the slide groove, thereby improving the limitation of the moving distance of the moving rod 23. In addition, with the cooperation of the bolt 25 and the first blind hole, when the moving rod 23 is pushed into the mounting barrel 21, the locking block 29 moves to contact the bottom wall of the slide groove, and the first blind hole corresponds to the first threaded through hole, thus making it convenient for the staff to fix it.

[0044] Furthermore, the moving component includes a second electric telescopic cylinder 18 and an electric wheel 11. Multiple electric telescopic cylinders are evenly distributed around the fixed plate 1, and the telescopic ends of multiple electric telescopic cylinders are connected to the outer peripheral surface of the fixed plate 1. The telescopic rods of multiple electric telescopic cylinders are connected to the electric wheel 11, and the electric wheel 11 can be moved to slide against the inner wall of the pipe.

[0045] Therefore, the electric wheel 11 can be effectively driven to move to abut against the inner wall of the pipe by the second electric telescopic cylinder 18, thereby completing the overall installation of the device. After abutting against the inner wall of the pipe, the angle of the fixed plate 1 can be limited by friction, thereby improving the overall stability of the device. The electric wheel 11 can also be used to move the device inside the pipe.

[0046] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
