Description

A self-rotating pipe cleaning device Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, and in particular, to a self-rotating pipeline cleaning device. Background Technology

[0002] A pipeline is a device used to transport gases, liquids, or fluids containing solid particles. Its applications are very wide, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. Over time, the medium transported within the pipeline will adhere to its inner walls to some extent, eventually affecting the pipeline's normal operation.

[0003] Currently, Chinese patent CN220760414U discloses a pipe cleaning robot, including a ring-shaped shell, a ring-shaped cleaning brush, and at least three track assemblies. The ring-shaped cleaning brush is driven to rotate by a drive assembly mounted on the ring-shaped shell. In use, the robot moves along the pipe under the drive of the track assemblies, while the drive assembly drives the ring-shaped cleaning brush to rotate and clean the inner wall of the pipe. However, the robot's movement along the pipe and the rotation of the ring-shaped cleaning brush are achieved through two drive sources: the track assemblies and the drive assemblies. This significantly increases the production cost of the pipe cleaning device. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-rotating pipe cleaning device.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A self-rotating pipe cleaning device includes a body, a mounting frame rotatably mounted on the body, a plurality of Mecanum wheels arranged circumferentially on the mounting frame, and a cleaning component also mounted on the mounting frame. The body also has a power mechanism adapted to drive the mounting frame to rotate.

[0007] Preferably, the Mecanum wheel is radially movable, and the mounting bracket is further provided with a drive mechanism adapted to drive the Mecanum wheel to move radially.

[0008] Preferably, the drive mechanism includes a rotatable cam disk, on which a plurality of cam drive parts are arranged circumferentially, each of the plurality of cam drive parts corresponding to a plurality of Mecanum wheels, and a drive rod is provided on the connecting frame of the Mecanum wheel, the drive rod cooperating with the cam drive parts.

[0009] Preferably, the cam drive unit includes a cam groove formed on the cam disk, and the end of the drive rod is provided with a cam shaft, which is adapted to the cam groove.

[0010] Preferably, the side wall of the mounting bracket is provided with a plurality of support portions, and the inner wall of the cam disk is supported on the outer wall of the plurality of support portions.

[0011] Preferably, a mounting part is also provided on the side wall of the mounting bracket, and the drive rod is slidably adapted to the mounting part.

[0012] Preferably, the mounting bracket is provided with a first gear ring, the cam disk is provided with a second gear ring, and the power mechanism includes a rotatable drive gear driven by a first drive member, and the drive gear is also adapted to move axially to mesh with the first gear ring or the second gear ring respectively.

[0013] Preferably, a splined shaft is provided on the output shaft of the first drive component, the drive gear is slidably adapted to the splined shaft, and a toggle mechanism is also provided on the machine body, the toggle mechanism being used to drive the drive gear to slide.

[0014] Preferably, the sidewall of the cam disk is further provided with a toothed structure in the circumferential direction, the mounting bracket is further provided with a locking tooth in a spring-loaded manner, and a push rod is connected to the drive end of the actuating mechanism; when the actuating mechanism drives the drive gear to mesh with the second gear ring, the push rod pushes the locking tooth to disengage from the toothed structure; when the actuating mechanism drives the drive gear to mesh with the first gear ring, the locking tooth springs and recouples to the toothed structure.

[0015] Preferably, the mounting brackets are provided at both ends of the body, and the actuating mechanism is disposed between the two mounting brackets. The actuating mechanism includes a support base and a rotatable power rod disposed on the support base and driven by a second driving member. Push blocks are slidably adapted on both sides of the support base. A connecting rod is hinged between the end of the power rod and the corresponding push block, and a fixing rod is also provided between the push block and the corresponding driving gear.

[0016] The beneficial effects of this invention are:

[0017] 1. The device can rotate inside the pipeline through the power mechanism and Mecanum wheel. At the same time, the cleaning component can also rotate under the drive of the mounting frame. That is, the movement of the device along the pipeline and the rotation of the cleaning component are both accomplished by the power mechanism, thereby reducing the production cost of the pipeline cleaning device.

[0018] 2. The rotation of the cam disc drives the Mecanum wheel to move radially, thus making the present invention applicable to the cleaning needs of pipes of different diameters.

[0019] 3. The power mechanism can provide power to rotate the mounting bracket and the cam disc by means of the drive gear, the first gear ring and the second gear ring, thereby further reducing the power source requirements.

[0020] 4. The axial movement of the drive gear is achieved through a toggle mechanism. Simultaneously, the toggle mechanism also drives the locking teeth to perform the desired locking and disengaging actions within the toothed structure. During locking, the cam disc is less likely to rotate unexpectedly, allowing the Mecanum wheel to stably adhere to the inner wall of the pipe, thus enabling the device to move.

[0021] 5. The machine body has a hollow structure, and the dirt on the pipe wall cleaned by the cleaning components can be discharged from the machine body to the rear end, thereby avoiding blockage. Attached Figure Description

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] As shown in Figures 1 to 4, a self-rotating pipe cleaning device includes a body 1, a mounting frame 2 rotatably mounted on the body 1, and a plurality of Mecanum wheels 3 arranged circumferentially on the mounting frame 2. A cleaning component 4 is also mounted on the mounting frame 2. Furthermore, a power mechanism 5 is provided on the body 1, which drives the mounting frame 2 to rotate. Subsequently, under the action of the Mecanum wheels 3, the entire device moves within the pipe in a rotating manner, thereby cleaning the inner wall of the pipe.

[0029] In some embodiments, a plurality of mounting portions 13 are provided on the side wall of the mounting bracket 2, and a plurality of Mecanum wheels 3 are correspondingly disposed on the plurality of mounting portions 13. Furthermore, in order to achieve adaptability of the Mecanum wheels 3 to pipes of different diameters, in this disclosure, the Mecanum wheels 3 are also adapted to be capable of radial movement. Accordingly, the mounting bracket 2 is also provided with a drive mechanism 6, which drives the Mecanum wheels 3 to move radially within the pipe and abut against the inner wall of the pipe to achieve the adaptive function.

[0030] For example, the Mecanum wheel 3 specifically includes a connecting frame and a wheel body rotatably disposed within the connecting frame. The connecting frame also has a drive rod 9, which passes through a connecting hole on the mounting portion 13 to achieve a sliding fit with the mounting portion 13. That is, as the drive rod 9 slides within the connecting hole, the Mecanum wheel 3 can undergo the aforementioned radial movement. Preferably, each connecting frame can be provided with at least two wheels to increase stability, while the mounting portion 13 and the Mecanum wheel 3 can preferably be provided with three wheels in the circumferential direction. Furthermore, the wheel body and the connecting frame can be connected by a spring, which can dampen the wheel body, for example, enabling the wheel body to adaptively overcome uneven protrusions encountered within the pipe wall.

[0031] The drive mechanism 6 includes a rotatable cam disk 7, and a plurality of cam drive parts 8 are arranged circumferentially on the cam disk 7. Obviously, the plurality of cam drive parts 8 correspond one-to-one with a plurality of Mecanum wheels 3. Specifically, the drive rod 9 passes through the connecting hole and cooperates with the cam drive part 8. Therefore, when the cam disk 7 rotates, the drive rod 9 will slide in the connecting hole under the action of the cam drive part 8.

[0032] In a preferred embodiment, the cam drive unit 8 is specifically a cam groove 10 formed on the cam disk 7, and the end of the drive rod 9 is provided with a cam shaft 11. For example, each Mecanum wheel 3 has two drive rods 9 on its connecting frame, and the cam shaft 11 is disposed between the two drive rods 9. More specifically, the two drive rods 9 are located on both sides of the cam disk 7, and the cam shaft 11 passes through and is adapted to the cam groove 10 accordingly.

[0033] As a preferred installation method for the cam disc 7, several support portions 12 are also provided on the side wall of the mounting bracket 2, and the inner wall of the cam disc 7 is supported on the outer wall of the support portions 12. The pipe cleaning device disclosed herein can have the following operating process:

[0034] The machine body 1 is placed into the pipe to be cleaned. Then, the cam disk 7 rotates as expected. With the cooperation of the cam drive unit 8 and the drive rod 9, the Mecanum wheel 3 will be pushed out until it abuts against the inner wall of the pipe. Then, the power mechanism 5 drives the mounting bracket 2 to rotate. The several Mecanum wheels 3 that rotate will drive the device to move along the pipe in a spiral manner. During this process, the cleaning room cleans the inner wall of the pipe.

[0035] In order to enable the power mechanism 5 to drive the rotation of the cam disk 7, the mounting bracket 2 is provided with a first gear ring 14, the cam disk 7 is provided with a second gear ring 15, and the power mechanism 5 includes a drive gear 17 driven by a first drive member 16, and the drive gear 17 is also adapted to be able to move axially to mesh with the first gear ring 14 or the second gear ring 15 respectively.

[0036] It is understood that when the drive gear 17 is engaged with the second gear ring 15, the power output by the first drive member 16 will be used to drive the rotation of the cam disk 7; when the drive gear 17 is engaged with the first gear ring 14, the power output by the first drive member 16 will be used to drive the rotation of the mounting bracket 2.

[0037] In some embodiments, the first drive member 16 may be composed of multiple drive sources, such as an electric cylinder and a motor mounted on the output shaft of the electric cylinder, with the drive gear 17 directly fixed on the output shaft of the motor. It is conceivable that, under the thrust of the electric cylinder, the drive gear 17 will mesh with either the first gear ring 14 or the second gear ring 15, and subsequently, the motor will output torque through the drive gear 17 to drive the mounting bracket 2 or the cam disc 7 to rotate.

[0038] Alternatively, the first drive element 16 may consist solely of a rotary drive source. For example, a splined shaft 18 may be mounted on the output shaft of the first drive element 16, and the drive gear 17 may be slidably fitted onto the splined shaft 18 via a key. Furthermore, the housing 1 may also be equipped with a toggle mechanism 19, which allows the drive gear 17 to move on the splined shaft 18, thereby achieving separate meshing on the first gear ring 14 or the second gear ring 15.

[0039] For example, the aforementioned rotary drive source can be a motor, and a gear set can be engaged at the output end of the motor to achieve speed reduction. The gear set is equipped with an output shaft for connecting the spline shaft 18. In a preferred example, a toothed structure 20 is circumferentially provided on the side wall of the cam disk 7, and a locking tooth 21 is spring-loaded on the mounting bracket 2. For example, the locking tooth 21 can be abutted against one side of the cam disk 7 by a spring (not shown). A push rod 22 is also connected to the drive end of the actuating mechanism. While the actuating mechanism performs the aforementioned driving action on the drive gear 17, the locking tooth 21 will be coupled or disengaged within the toothed structure 20 under the pushing action of the push rod 22 and the reset action of the spring. Based on this, the pipe cleaning device disclosed herein can also have the following usage process:

[0040] 1. After the pipe to be cleaned is placed into the machine body 1, the actuating mechanism will actuate the drive gear 17 to slide and mesh with the second gear ring 15. At this time, the torque of the motor will be transmitted to the second gear ring 15 through the spline shaft 18 and the drive gear 17 to drive the cam disk 7 to rotate. Then the wheel body of the Mecanum wheel 3 will abut against the inner wall of the pipe. During this period, the locking tooth 21 will be disengaged from the tooth structure 20 under the push of the push rod 22 to satisfy the rotational freedom of the cam disk 7.

[0041] 2. The actuating mechanism disengages the drive gear 17 from the second gear ring 15 and engages with the first gear ring 14. At this time, the torque of the motor is transmitted to the first gear ring 14 through the spline shaft 18 and the drive gear 17, so as to drive the mounting bracket 2 to rotate. Therefore, the device can move in the pipe under the action of the Mecanum wheel 3. During this period, the push rod 22 gradually disengages from the locking tooth 21. Then the locking tooth 21 will be reset under the action of the spring and recoupled into the tooth structure 20, which can limit the rotation of the cam disk 7 to ensure the stability of the contact between the wheel body of the Mecanum wheel 3 and the inner wall of the pipe.

[0042] In a preferred embodiment, the second gear ring 15 may be attached to the sidewall of a plurality of support portions 12, and disposed adjacent to the first gear ring 14. Furthermore, the first gear ring 14 and the second gear ring 15 are preferably of the same diameter to facilitate switching engagement between the drive gear 17 and the first gear ring 14. Of course, the first gear ring 14 and the second gear ring 15 may also be configured with different diameters, and the drive gear 17 may be configured accordingly in a stepped shape, thus also achieving the function of power switching.

[0043] For example, a locking disc is slidably mounted on the body 1, and several locking teeth 21 are arranged circumferentially on the side wall of the locking disc, while several toothed structures 20 are correspondingly arranged on the side wall of the mounting bracket 2. It can be understood that when the actuating mechanism actuates the drive gear 17, the push rod 22 will push the locking disc to move, thereby disengaging the locking teeth 21 from the toothed structure 20. To ensure the stability of the actuation of the locking disc, two actuating mechanisms can also be provided on the body 1. These two actuating mechanisms can have the same structure, the difference being that one actuating mechanism can be attached to the drive gear 17, while the other actuating mechanism does not need to be attached to the drive gear 17 but only has a push rod 22 on its driving end.

[0044] In some embodiments, mounting brackets 2 are provided at both ends of the body 1, that is, cleaning components 4 are provided at both ends of the body 1. The two cleaning components 4 may have different structures and different functions as will be described below, but by providing two cleaning components 4, the cleaning effect of the device on the pipe can be greatly increased. Specifically, the gear set of the power mechanism 5 can output two coaxially arranged output shafts, and the two output shafts are respectively used to drive the rotation of the mounting brackets 2 on both sides and the cam disks 7 on both sides.

[0045] The actuating mechanism preferably includes a support base 24 disposed between two mounting brackets 2 and a rotatable power rod 26 disposed on the support base 24 and driven by a second drive member 25. Furthermore, push blocks 27 are slidably fitted on both sides of the support base 24, the push blocks 27 constituting the drive end of the actuating mechanism described above, and the end of the power rod 26 is hinged to the corresponding push block 27 via a connecting rod 28. A fixing rod 29 is provided between the push block 27 and the corresponding drive gear 17.

[0046] Therefore, the second driving member 25 can drive the power rod 26 to rotate, and then simultaneously drive the two push blocks 27 to slide. In this way, the push blocks 27 will realize the sliding of the drive gear 17 and the disengagement of the locking teeth 21 in the tooth structure 20 through the fixed rod 29 and the moving rod, respectively.

[0047] In a preferred embodiment, the body 1 may be a hollow structure, and the cleaning component 4 on the traveling end of the body 1 may include a guide plate 30, which is specifically funnel-shaped and engages with the inner cavity of the body 1. In addition, the end of the guide plate 30 is provided with cleaning teeth 31. The cleaning component 4 on the other end of the body 1 may include a mounting plate 32, which is also a hollow structure, and the side wall of the mounting plate 32 is provided with bristles 33.

[0048] As the device moves along the pipe, the cleaning element 4 (i.e., cleaning teeth 31) on the traveling end of the machine body 1 can roll up the dirt attached to the inner wall of the pipe and cut the hard scale layer. Then the dirt will be discharged to the rear end through the machine body 1. The cleaning element 4 (i.e., bristles 33) on the rear end of the machine body 1 can perform secondary cleaning on the inner wall of the pipe, thereby achieving a better pipe cleaning effect.

[0049] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
