Description

Technical Field

[0001] This application relates to the field of pipeline dredging technology, and in particular to a pipeline cleaning device. Background Technology

[0002] In urban drainage systems and industrial pipelines, sewer blockage is a common problem, usually caused by the accumulation of vegetable scraps, grease, dirt, or other solid waste. Currently, traditional pipe cleaning equipment (such as high-pressure water guns, mechanical drain springs, or rotating steel wires) can handle simple straight or gently curved pipes, but they have significant limitations when dealing with U-shaped pipes, S-shaped pipes, pipes with multiple bends, or pipes with changing diameters. For example, rigid tools are difficult to conform to the complex curves of pipes, resulting in the inability to completely remove sludge, especially highly adhesive grease or fibrous debris. Mechanical force may scratch the inner wall of the pipe, or even cause old pipes to rupture due to excessive torque, leading to secondary leaks or structural damage. Traditional equipment relies on manual angle adjustment, which is inefficient for working on vertical pipe sections or in narrow spaces.

[0003] Therefore, there is an urgent need to design a pipeline cleaning device that can adapt to complex pipeline cleaning, reduce labor costs, and ensure safety performance. Summary of the Invention

[0004] The main objective of this application is to at least solve one of the technical problems existing in the prior art, and to propose a pipeline cleaning device that can adapt to complex pipeline cleaning, reduce labor costs, and ensure safety performance.

[0005] To achieve the above objectives, embodiments of this invention provide a pipe cleaning device, comprising: a traveling device and a cleaning device;

[0006] The walking device includes multiple wheel assemblies and multiple swing assemblies. Any two wheel assemblies are connected through the swing assemblies. The wheel assemblies are attached to the inner wall of the pipe and move back and forth along the inner wall of the pipe.

[0007] The cleaning device includes a connecting component, a first driving component, a second driving component, and a drill bit assembly. The connecting component is connected to the swing component located at the front end of the walking device and the drill bit assembly, respectively. The first driving component and the second driving component are both connected to the drill bit assembly. The first driving component is used to control the drill bit assembly to retract and open, and the second driving component is used to control the drill bit assembly to rotate.

[0008] According to an embodiment of the present invention, a pipe cleaning device has at least the following advantages: By setting a wheel assembly, the wheel assembly can adapt to pipes of different diameters and move back and forth along the inner wall of the pipe, and can enter relatively deep variable diameter pipes on its own. This results in high operational efficiency and eliminates the need for manual labor to pull the end of the pipe back, reducing labor costs. When the pipe cleaning device moves to a curved area in the pipe, under the pressure of the curved inner wall of the pipe and the driving action of the wheel assembly, the swinging component between any two wheel assemblies can swing up, down, left, and right in coordination with the curved area in the pipe, thereby causing the pipe cleaning device to bend into a shape similar to the curved area, easily passing through complex curved areas and cleaning them. When encountering a blockage, the first drive assembly controls the drill bit assembly to retract or open to drill and disperse the blockage or clamp and pull it out. The second drive assembly controls the rotation of the drill bit assembly. Under the coordinated action of the first and second drive assemblies, the drill bit assembly is controlled to retract and rotate to drill and disperse the blockage, completing the pipe unblocking.

[0009] In some embodiments, the wheel assembly includes a circular frame, a plurality of omnidirectional rollers, a plurality of racks, a third drive assembly, and a transmission assembly.

[0013] In some embodiments, a second protective cover is further included. The connecting assembly includes a connecting frame, a second motor, a lead screw, a positioning sleeve, and a sliding sleeve. The second protective cover is fitted over the outside of the drill bit assembly and the sliding sleeve. One end of the connecting frame is connected to the swing assembly at the front end of the traveling device, and the other end of the connecting frame is connected to the second protective cover. The second motor, the lead screw, and the positioning sleeve are all built into the connecting frame. One end of the second motor, the positioning sleeve, and the sliding sleeve is connected to the lead screw. The second motor is used to control the rotation of the lead screw to move the sliding sleeve back and forth relative to the second protective cover. The other end of the sliding sleeve is connected to the drill bit assembly.

[0014] In some embodiments, the connecting component further includes a limiting block, and a limiting groove is provided on the second protective cover. The limiting block is disposed on the outside of the sliding sleeve, and the limiting groove is used to restrict the sliding of the limiting block.

[0015] In some embodiments, the drill bit assembly includes multiple drill bits, a tripod, multiple drill bit connecting rods, multiple bent connecting rods, multiple third gears, and multiple third motors. The drill bits are disposed above the tripod via the drill bit connecting rods. The third gears and the first drive assembly are both disposed below the tripod, and the third gears are meshed with the first drive assembly. One end of the bent connecting rod is connected to one end of the drill bit connecting rod, and the other end of both the drill bit connecting rod and the other end of the bent connecting rod are connected to the third gear.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0032] In urban drainage systems and industrial pipelines, sewer blockage is a common problem, usually caused by the accumulation of vegetable scraps, grease, dirt, or other solid waste. Currently, traditional pipe cleaning equipment (such as high-pressure water guns, mechanical drain springs, or rotating steel wires) can handle simple straight or gently curved pipes, but they have significant limitations when dealing with U-shaped pipes, S-shaped pipes, pipes with multiple bends, or pipes with changing diameters. For example, rigid tools are difficult to conform to the complex curves of pipes, resulting in the inability to completely remove sludge, especially highly adhesive grease or fibrous debris. Mechanical force may scratch the inner wall of the pipe, or even cause old pipes to rupture due to excessive torque, leading to secondary leaks or structural damage. Traditional equipment relies on manual angle adjustment, which is inefficient for working on vertical pipe sections or in narrow spaces.

[0033] This invention provides a pipeline cleaning device that can adapt to complex pipeline cleaning, reduce labor costs, and ensure safety performance.

[0034] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] Reference Figures 1-3 This invention application proposes a pipe cleaning device, including: a walking device and a cleaning device; the walking device includes multiple wheel assemblies 1 and multiple swing assemblies 2, any two wheel assemblies 1 are connected by swing assemblies 2, the wheel assemblies 1 are in contact with the inner wall of the pipe and move back and forth along the inner wall of the pipe; the cleaning device includes a connecting assembly, a first driving assembly, a second driving assembly 6 and a drill bit assembly 3, the connecting assembly is connected to the swing assembly 2 and the drill bit assembly 3 located at the front end of the walking device respectively, the first driving assembly and the second driving assembly 6 are both connected to the drill bit assembly 3, the first driving assembly is used to control the drill bit assembly 3 to retract and open, and the second driving assembly 6 is used to control the rotation of the drill bit assembly 3.

[0036] According to an embodiment of the present invention, a pipe cleaning device is provided. By setting a wheel assembly 1, the wheel assembly 1 can adapt to pipes of different diameters and move back and forth along the inner wall of the pipe. It can enter relatively deep pipes with varying diameters on its own, resulting in high mobility and eliminating the need for manual labor to pull the end of the pipe back, thus reducing labor costs. When the pipe cleaning device moves to a curved area in the pipe, under the pressure of the curved inner wall of the pipe and the driving action of the wheel assembly 1, the swing assembly 2 between any two wheel assemblies 1 can swing up, down, left, and right in coordination with the curved area in the pipe, thereby making the pipe cleaning device bend into a shape similar to the curved area, easily passing through complex curved areas and cleaning them. When encountering a blockage, the first drive assembly controls the drill claw assembly 3 to retract or open to drill and disperse the blockage or clamp the blockage and pull it out. The second drive assembly 6 controls the rotation of the drill claw assembly 3. Under the coordinated action of the first drive assembly and the second drive assembly 6, the drill claw assembly 3 is controlled to retract and rotate to drill and disperse the blockage, thus completing the pipe unblocking.

[0037] In some embodiments, refer to Figure 4 , Figure 5 The wheel assembly 1 includes a circular frame, multiple universal rollers 130, multiple racks 140, a third drive assembly 150, and a transmission assembly. The transmission assembly is built into the circular frame. One end of the universal rollers 130 is connected to one end of the racks 140, and the other end of the racks 140 is meshed with the transmission assembly. The transmission assembly is used to drive the racks 140 to rotate synchronously to adjust the angle of the universal rollers 130. The third drive assembly 150 is connected to the universal rollers 130 and is used to control the rotation of the universal rollers 130.

[0038] It should be noted that the third drive assembly 150 is connected to the universal roller 130. The third drive assembly 150 controls the rotation direction of the universal roller 130, thereby enabling the wheel assembly 1 to move back and forth along the inner wall of the pipe. The universal roller 130 is connected to one end of the rack 140, and the other end of the rack 140 is meshed with the transmission assembly. The transmission assembly is used to drive the rack 140 to rotate synchronously, so that the angle between the universal roller 130 connected to one end of the rack 140 and the circular frame increases or decreases. When the angle between the universal roller 130 and the circular frame increases, the corresponding dimension of the rack 140 extending out of the circular frame increases, and the wheel assembly 1 can fit into a wider pipe. When the angle between the universal roller 130 and the circular frame decreases, the corresponding dimension of the rack 140 extending out of the circular frame decreases, and the wheel assembly 1 can fit into a narrower pipe.

[0039] Preferably, the third drive component 150 can be a motor, which drives the universal roller 130 connected to the motor to rotate by starting the motor to rotate.

[0040] Preferably, the universal roller 130 is made of nylon or plastic, which has strong friction and can adhere more firmly to the inner wall of the pipe.

[0041] Preferably, there are 5 universal rollers 130 and the number of racks 140 is the same as the number of universal rollers 130.

[0042] In some embodiments, refer to Figure 5 The transmission assembly includes a first gear 161, a second gear 162, and a first motor 163. The circular frame includes a chassis 110 and a cover plate 120. The chassis 110 is disposed below the cover plate 120 and is detachably connected to the cover plate 120. The cover plate 120 is also provided with multiple extension arms 121. The cover plate 120 is sleeved above the first gear 161. The other ends of the second gear 162 and multiple racks 140 are meshed with the first gear 161. The first motor 163 is used to drive the second gear 162 to rotate. Openings are provided on the other ends of the second gear 162 and multiple racks 140. The multiple extension arms 121 are rotatably connected to the openings on the second gear 162 and the openings on the other ends of the multiple racks 140 respectively through connecting parts.

[0043] It should be noted that both the chassis 110 and the cover plate 120 have openings in the middle, allowing two adjacent swing components 2 to pass through these openings and connect together, making the overall structure more compact. An annular boss is provided below the cover plate 120, which engages with the first gear 161. The annular boss serves to confine the first gear 161 between the chassis 110 and the cover plate 120. Multiple connecting pieces are used to confine the other ends of the first gear 161 and multiple racks 140 between the extension arm 121 and the chassis 110. This ensures that each rack 140 and the second gear 162 are evenly distributed and cooperate with each other between the chassis 110 and the cover plate 120. Under the coordinated action of the second gear 162, the first motor 163, and the multiple racks 140, the universal roller 130 can fit into pipes of different diameters. Specifically, when the first motor 163 starts, it controls the rotation direction of the second gear 162, thereby synchronously driving the first gear 161 and the rack 140 to rotate, so that the angle between the universal roller 130 connected to one end of the rack 140 and the circular frame increases or decreases.

[0044] In some embodiments, refer to Figure 6The swing assembly 2 includes two sets of rotating parts, which are arranged in a cross shape between any two adjacent wheel assemblies 1. The rotating parts include a first connecting seat 211, a second connecting seat 212, two first semi-circular gears 213 and two second semi-circular gears 214. The two ends of the first connecting seat 211 are respectively connected to the two first semi-circular gears 213, and the two ends of the second connecting seat 212 are respectively connected to the two second semi-circular gears 214. The first semi-circular gears 213 and the second semi-circular gears 214 are meshed. The two ends of the first connecting seat 211 are rotatably connected to the two ends of the second connecting seat 212 through two connecting rods 216. The middle part of the first connecting seat 211 is connected to the middle part of the second connecting seat 212 through a universal joint connector 215.

[0045] It should be noted that in the swing assembly 2, the first connecting seat 211 of both sets of rotating parts is connected to the adjacent wheel assembly 1, and the second connecting seat 212 of the two sets of rotating parts is vertically connected.

[0046] It should be noted that when the pipe cleaning equipment moves to a curved area in the pipe, the rotating component in the swing assembly 2 can swing up, down, left, and right in coordination with the curved area in the pipe, thereby causing the pipe cleaning equipment to bend into a shape similar to the curved area, easily passing through the complex curved area and cleaning the curved area. Specifically, in the rotating component, through the meshing connection of two sets of first semi-circular gears 213 and second semi-circular gears 214, under the compression of the curved inner wall of the pipe and the driving action of the wheel assembly 1, the first semi-circular gears 213 and second semi-circular gears 214 rotate relative to each other, causing the rotating component to bend into a shape similar to the curved area. In addition, since the two sets of rotating components are arranged in a cross shape between any two adjacent wheel assemblies 1, and the first semi-circular gears 213 and second semi-circular gears 214 in one rotating component are perpendicular to the first semi-circular gears 213 and second semi-circular gears 214 in the other rotating component, in the swing assembly 2, one rotating component can be used for left and right rotation, and the other rotating component can be used for up and down rotation.

[0047] It should be noted that, compared with the technical solution that requires a driving device to control the swing component 2 to swing up, down, left and right, the design in this application that connects any two wheel components 1 through the swing component 2 allows the swing component 2 to adaptively adjust its angle under the pressure of the curved inner wall of the pipe and the driving action of the wheel components 1 on both sides.

[0048] In some embodiments, refer to Figure 1 It also includes a first protective cover 7, which is fitted onto the outside of the rotating component.

[0049] It is understandable that the first protective cover 7 is provided on the outside of the rotating component so that the first semi-circular gear 213 and the second semi-circular gear 214 in the rotating component can avoid corrosion from sewage in the pipe and blockage by fine objects, which helps the rotating component to operate more stably and extends the service life of the rotating component.

[0050] In some embodiments, refer to Figure 1 , Figure 3 as well as Figure 7 It also includes a second protective cover 8. The connecting assembly includes a connecting frame 410, a second motor 420, a lead screw 430, a positioning sleeve 440, and a sliding sleeve 450. The second protective cover 8 is sleeved on the outside of the drill bit assembly 3 and the sliding sleeve 450. One end of the connecting frame 410 is connected to the swing assembly 2 at the front end of the traveling device, and the other end of the connecting frame 410 is connected to the second protective cover 8. The second motor 420, the lead screw 430, and the positioning sleeve 440 are all built into the connecting frame 410. One end of the second motor 420, the positioning sleeve 440, and the sliding sleeve 450 are all connected to the lead screw 430. The second motor 420 is used to control the rotation of the lead screw 430 so that the sliding sleeve 450 moves back and forth relative to the second protective cover 8. The other end of the sliding sleeve 450 is connected to the drill bit assembly 3.

[0051] Understandably, since the second motor 420 is used to control the rotation of the lead screw 430 to move the sliding sleeve 450 back and forth relative to the second protective cover 8, and the other end of the sliding sleeve 450 is connected to the drill bit assembly 3, when the second motor 420 is started, the sliding sleeve 450 can synchronously drive the drill bit assembly 3 to extend out of the second protective cover 8 or retract into the second protective cover 8.

[0052] It should be noted that a nylon baffle 820 is provided at the front end of the second protective cover 8. When the drill bit assembly 3 extends out of the second protective cover 8, the nylon baffle 820 flips outward along with the drill bit assembly 3. When the drill bit assembly 3 retracts into the second protective cover 8, the nylon baffle 820 retracts inward along with the drill bit assembly 3. By providing the nylon baffle 820, on the one hand, it helps the drill bit assembly 3 to flexibly extend or retract into the second protective cover 8. On the other hand, it helps to form a shielding layer after the drill bit assembly 3 retracts into the second protective cover 8, preventing fine blockages from entering the second protective cover 8.

[0053] It should be noted that, referring to Figure 3 A groove is provided inside the sliding sleeve 450 for housing the second drive component 6, which is connected to the drill bit component 3. The second drive component 6 is used to control the rotation of the drill bit component 3. By providing a groove inside the sliding sleeve 450, the overall integration of the pipe cleaning equipment is further improved, the size of the pipe cleaning equipment is reduced, and the pipe cleaning equipment is more convenient to carry and place, which helps to improve the user experience.

[0054] In some embodiments, refer to Figure 3 The connecting component also includes a limiting block 460, and a limiting groove 810 is provided on the second protective cover 8. The limiting block 460 is located on the outside of the sliding sleeve 450, and the limiting groove 810 is used to limit the sliding of the limiting block 460.

[0055] It should be noted that by setting a limiting block 460 on the outside of the sliding sleeve 450 and a limiting groove 810 on the second protective cover 8, the sliding sleeve 450 can only move back and forth within the length range of the limiting groove 810. This helps to prevent the sliding sleeve 450 from causing the drill bit assembly 3 to extend too far outward from the second protective cover 8 or retract too much inward from the second protective cover 8, ensuring that the drill bit assembly 3 can operate stably outside the second protective cover 8 and can be accommodated in the second protective cover 8 to the greatest extent after operation.

[0056] In some embodiments, refer to Figure 8 The drill bit assembly 3 includes multiple drill bits 310, a tripod 390, multiple drill bit connecting rods 320, multiple bent connecting rods 330, multiple third gears 340, and multiple third motors 350. The drill bits 310 are positioned above the tripod 390 via the drill bit connecting rods 320. The third gears 340 and the first drive assembly are both positioned below the tripod 390, and the third gears 340 are meshed with the first drive assembly. One end of the bent connecting rod 330 is connected to one end of the drill bit connecting rod 320, and the other end of both the drill bit connecting rod 320 and the bent connecting rod 330 are connected to the third gear 340. A cutting element 360 is provided on the inner surface of the drill bit 310. The third motors 350 are connected to the drill bit 310 and are used to control the rotation of the drill bit 310.

[0057] It should be noted that since the third gear 340 is meshed with the first drive assembly, and the other end of the bending link 330 is connected to the third gear 340, when the first drive assembly is started, it will drive the third gear 340 to rotate upward or downward, and simultaneously adjust the angle of the bend of the bending link 330. In addition, when the angle of the bend of the bending link 330 decreases, the bending link 330 will pull the drill bit link 320 to open, thereby causing the drill bit 310 connected to the drill bit link 320 to open. When the angle of the bend of the bending link 330 increases, the bending link 330 will drive the drill bit link 320 to close, thereby causing the drill bit 310 connected to the drill bit link 320 to close.

[0058] Understandably, when the first drive assembly is activated, the drill bit 310 connected to the drill bit connecting rod 320 opens. At this time, the third motor 350 is activated to control the drill bit 310 to rotate, rotating the cutting element 360 located on the inner surface of the drill bit 310 to the outside. Further, the second drive assembly 6 is activated to control the cutting element 360 located on the outside of the drill bit 310 to rotate in order to cut the hard blockage.

[0059] Preferably, there are 3 drill bits 310, and the number of bending connecting rods 330 and drill bit connecting rods 320 is the same as the number of drill bits 310.

[0060] It should be noted that when the three drill bits 310 are closed together, they form a cone-shaped structure, which is smaller in the front and larger in the back, making it easy to rotate and clear blockages. If it is difficult to clear the blockage by rotating the drill bits 310 alone, the drill bits 310 can be opened and rotated to make the cutting element 360 located on the inner surface of the drill bits 310 turn to the outside. The sharper cutting element 360 can then drill into the blockage, providing a variety of clearing operations.

[0061] In some embodiments, refer to Figure 8 The first drive assembly includes a fourth motor 510 and a screw 520. The fourth motor 510 is connected to the connecting assembly and the screw 520 respectively. The screw 520 is meshed with a plurality of third gears 340 respectively. The fourth motor 510 is used to control the rotation of the screw 520.

[0062] It should be noted that the fourth motor 510 is connected to the connecting assembly via the rotary seat 370. The fourth motor 510 is located between the rotary seat and the drill bit assembly 3, and the drill bit assembly 3 is located above the rotary seat via the support rod 380.

[0063] Preferably, there are three third gears 340.

[0064] It should be noted that when the fourth motor 510 starts, it drives the screw 520 to rotate. The third gear 340 rotates up or down under the drive of the screw 520, and simultaneously adjusts the angle of the bend of the bending connecting rod 330, thereby realizing the control of the opening or closing of the drill bit 310.

[0065] In some embodiments, refer to Figure 9 The outer surface of the drill bit 310 is provided with multiple thread layers 311, and the cutting part 360 and the inner surface of the drill bit 310 are set at a first inclination.

[0066] It should be noted that the front end of the drill jaw 310 is acute-angled, which can ensure that the multiple drill jaws 310 can achieve a clamping effect after being retracted. The outer surface of the drill jaw 310 is provided with multiple thread layers 311, which helps to enhance the drilling ability of the drill jaw 310. In addition, the cutting element 360 and the inner surface of the drill jaw 310 are set at a first inclination, which helps to prevent the cutting element 360 from cutting the inner wall of the pipe during operation.

[0067] In some embodiments, various sensors, such as cameras, lidar, and ultrasonic sensors, are also included. By setting various sensors in the drill bit assembly 3, users can monitor the condition inside the pipe in real time. The pipe cleaning equipment can detect and identify blockages, pipe damage, abnormal objects or liquids, etc., and provide early warnings or timely feedback to users.

[0068] In some embodiments, an LED light is also included, which is disposed in the drill bit assembly 3 to facilitate the pipe cleaning device to work inside the dark pipe and help enhance the cleaning effect.

[0069] Obviously, the embodiments described above are merely some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the scope of protection of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
