Description

Technical Field

[0001] This invention relates to the technical field of pipeline cleaning, and in particular to an external pipeline cleaning platform. Background Technology

[0002] In today's era of rapid automation and intelligent development, pipeline robot technology has been gradually applied to various fields. Among these, with increasing societal focus on pipeline safety and cleanliness, pipeline robots have become a major research direction. Whether in oil and gas transportation, urban wastewater treatment, or industrial pipeline maintenance, pipeline robots play a crucial role. To better meet these demands, extremely high requirements are placed on the performance of pipeline robots in all aspects. Current technology still has room for improvement in areas such as cleaning efficiency, pipeline constraints, and flexibility.

[0003] Currently, several domestic patents for pipeline cleaning robots mention cleaning mechanisms with adaptive pipe diameters, achieving multi-pipe applicability through intelligent cleaning methods. Regarding cleaning tools, pipeline cleaning robots commonly use rotating and flexible brush heads. Foreign rotating brush heads are characterized by high-efficiency cleaning, thoroughly removing contaminants from pipes through high-speed rotation. They are suitable for smaller diameter pipes, are easy to operate, and have low maintenance costs. Domestic flexible brush heads, on the other hand, emphasize softness and safety, conforming to the pipe's inner wall for gentle cleaning. They have a wide range of applications, especially suitable for situations requiring high surface finish. Choosing the appropriate brush head will help improve the efficiency and quality of pipeline cleaning.

[0004] Current pipe cleaning applications primarily focus on cleaning the inner walls of cylindrical pipes. By controlling the cleaning tools to operate within the pipe, the machine can remove dirt while simultaneously moving axially within the pipe. Existing pipe cleaning robot technology faces three main challenges: first, the cleaning tool bristles cannot achieve a 360° radial cleaning contact area, and the pressure applied is not adjustable, resulting in insufficient cleaning effectiveness; second, the cleaning efficiency before and after cleaning cannot be quantified; and third, when the cleaning efficiency does not meet expectations, there is no feedback to automatically adjust the cleaning tools for further cleaning.

[0005] Therefore, ensuring that cleaning efficiency meets expectations has become a pressing technical problem. Summary of the Invention

[0006] The purpose of this invention is to provide an external pipeline cleaning platform to address the problem that existing technologies cannot ensure that cleaning efficiency meets expectations.

[0007] To address the aforementioned technical problems, this invention provides an external pipe cleaning platform, comprising a chassis, a nozzle, a fluorescent lamp, a cleaning mechanism, a drive mechanism, and a camera.

Multiple brushes are arranged around the inner circumferential wall of the clamping area, and these brushes are movable structures that can move towards and away from the center of the clamping area. The drive mechanism drives the cleaning mechanism to move back and forth on the straight guide rail. The camera is mounted on the cleaning mechanism and is used to capture images of the fluorescent particles on the outer wall of the pipe to be cleaned. When the amount of captured fluorescent particles exceeds a preset value, the external pipe cleaning platform controls the multiple brushes to move towards the center of the clamping hole.

[0008] In one embodiment, the casing wall is provided with a through hole for the pipe to be cleaned to pass through, and the through hole is arranged opposite to the clamping area; the outer wall of the casing is provided with a plurality of positioning blocks around the through hole, and each of the plurality of positioning blocks is provided with a threaded hole for threaded connection of a locking bolt, and the tightening of the plurality of locking bolts is used to adjust the clamping force on the pipe to be cleaned.

[0009] In one embodiment, one side wall of the chassis is provided with a flip-openable and closable baffle, the opening and closing of which is used to switch the interior of the chassis to an exposed state or a concealed state.

[0011] In one embodiment, the cleaning mechanism further includes a base, a rotating ring, and a transmission module; the clamping area includes a first clamping hole and a second clamping hole arranged opposite to each other, the first clamping hole being disposed on the base and the second clamping hole being disposed on the turntable; the base is slidably mounted on the straight guide rail, and the base is driven to slide by the driving mechanism; the rotating ring is mounted in the first clamping hole in a rotatable manner, and a plurality of brushes are rotatably mounted on the rotating ring; the transmission module engages with teeth disposed on the outer peripheral wall of the turntable, and the transmission module is used to drive the turntable to rotate.

[0012] In one embodiment, the base has a cavity through which the first clamping hole passes; the rotating ring includes a first rotating ring and a second rotating ring, the first rotating ring being rotatably disposed on the side of the first clamping hole adjacent to the turntable, and the second rotating ring being rotatably disposed on the side of the first clamping hole away from the turntable; a plurality of brushes are arranged in a perforated shape around the first clamping hole; a portion of the brushes are rotatably mounted on the first rotating ring, and this portion of the brushes is disposed between the base and the turntable; another portion of the brushes are rotatably mounted on the second rotating ring, and this portion of the brushes is disposed within the cavity.

[0015] In one embodiment, the camera is mounted on the base, positioned on the side of the base away from the turntable, and the camera's shooting direction is downward.

[0016] In one embodiment, the drive mechanism includes a drive motor and a crank connecting rod; the output end of the drive motor is rotatably connected to one end of the crank connecting rod, and the other end of the crank connecting rod is rotatably connected to the cleaning mechanism.

[0017] The beneficial effects of this invention are as follows:

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] This invention provides an external pipeline cleaning platform, the implementation of which is as follows: Figures 1 to 7 As shown, it includes a chassis 10, a nozzle 20, a fluorescent lamp 30, a cleaning mechanism 40, a drive mechanism 50, and a camera 60.

[0039] Regarding the aforementioned chassis 10, as Figure 1 and Figure 2 As shown, the chassis 10 is a rectangular box structure. Inside the chassis 10, there is a straight guide rail 11. The straight guide rail 11 is arranged horizontally so that the cleaning mechanism 40 can be slidably installed on the straight guide rail 11, thereby realizing the cleaning operation of the cleaning mechanism 40 moving back and forth horizontally.

[0040] In order to clean the pipe to be cleaned, the pipe to be cleaned needs to be fixed on the external pipe cleaning platform. To achieve this, the pipe to be cleaned can be inserted from outside the chassis 10 into the chassis 10 to achieve the installation connection between the pipe to be cleaned and the cleaning mechanism 40. Alternatively, the chassis 10 can be designed with an exposed internal space so that the pipe to be cleaned can be placed directly inside the chassis 10 to achieve the installation connection between the pipe to be cleaned and the cleaning mechanism 40.

[0041] In this embodiment, a combination of the two design approaches described above is adopted; for example, from Figures 1 to 3It is understood that the casing 10 in this embodiment has a through hole 12 on its casing wall for the pipe to be cleaned to pass through. The through hole 12 connects the inside and outside of the casing 10 and is arranged opposite to the pipe clamping area 41 of the cleaning mechanism 40. Therefore, when installing and fixing the pipe to be cleaned, it is only necessary to pass the pipe to be cleaned through the through hole 12 and insert the pipe to be cleaned into the pipe clamping area 41.

[0042] And to ensure that the position of the pipe to be cleaned can be fixed after installation, such as Figure 1 As shown, this embodiment also provides multiple positioning blocks 13 around the pipe hole 12 on the outer wall of the chassis 10. Each positioning block 13 is provided with a threaded hole for threaded connection of a locking bolt 14. Therefore, when the multiple locking bolts 14 are turned to move the multiple locking bolts 14 toward the center of the pipe hole 12, the pipe to be cleaned can be clamped. Conversely, the clamping of the pipe to be cleaned can be released. That is, the turning of the multiple locking bolts 14 can be used to adjust the clamping force of the pipe to be cleaned.

[0043] In addition, to prevent light leakage at the through hole 12, this embodiment also provides a hanging rod 15 on the inner wall of the chassis 10 near the through hole 12. After hanging the light-shielding cloth on the hanging rod 15, the through hole 12 can be shielded, ensuring that the light emitted by the fluorescent lamp 30 will not leak out of the chassis 10.

[0044] And from Figures 1 to 3 As can be seen, this embodiment also has a flip-openable and closable baffle 16 on one side wall of the chassis 10. The baffle 16 is rotatably connected to the bottom of the chassis 10 by a pivot, so that the opening and closing of the baffle 16 can be used to switch the interior of the chassis 10 to an exposed state or a covered state. For example, when the baffle 16 is flipped upward, it can cover the interior of the chassis 10 to ensure that the cleaning process of the pipe to be cleaned can be carried out in a closed space, which not only avoids pollution to the external environment, but also ensures that the fluorescent lamp 30 and the camera 60 can better complete the recognition work. When the baffle 16 is flipped downward, it can remove the cover of the interior of the chassis 10, so that the interior of the chassis 10 is exposed, so that operation or cleaning and maintenance work can be carried out inside the chassis 10.

[0045] Regarding the nozzle 20 and fluorescent lamp 30, as Figure 2 As shown, the nozzle 20 and the fluorescent lamp 30 are located inside the housing 10. For example, the nozzle 20 is located at the top of the inner wall of the housing 10 and extends downward to the placement of the pipe to be cleaned, so that the nozzle 20 can spray fluorescent particles onto the outer wall of the pipe to be cleaned to achieve marking treatment of the pipe to be cleaned; while the fluorescent lamp 30 is located at the top of the housing 10 to irradiate the inside of the housing 10 from top to bottom, so that the fluorescent lamp 30 can be used to irradiate and display fluorescent particles.

[0046] Regarding the cleaning mechanism 40, such as Figures 2 to 7 As shown, the cleaning mechanism 40 has a clamping area 41 for the pipe to be cleaned to pass through, and the cleaning mechanism 40 has multiple brushes 42 around the inner peripheral wall of the clamping area 41. The multiple brushes 42 are movable structures that can move towards and away from the center of the clamping area 41. Therefore, after the pipe to be cleaned is installed in place, the multiple brushes 42 will surround the outer wall of the pipe to be cleaned. If it is necessary to strengthen the cleaning force of the pipe to be cleaned, it is only necessary to control the multiple brushes 42 to move towards the center of the clamping area 41, thereby strengthening the contact between the brushes 42 and the outer wall of the pipe to be cleaned.

[0047] In order to achieve the movement control of the brush 42, this embodiment adopts... Figures 2 to 7 The structure shown here includes a self-rotating turntable 43 and a circumferentially movable and self-rotating brush 42 in the cleaning mechanism 40.

[0048] Specifically, the turntable 43 is provided with a clamping area 41, so that the center of the turntable 43 is formed into a hollow ring structure. The turntable 43 is surrounded by multiple arc-shaped guide grooves 431 arranged in a circumferential manner around the clamping area 41. The concave arc of the multiple arc-shaped guide grooves 431 is arranged in the same circumferential direction and in the same manner. Connecting rods 44 are rotatably connected to the sides of the multiple arc-shaped guide grooves 431.

[0049] The brush 42 is designed as a crescent shape that is thick in the middle and narrow at both ends. Multiple brushes 42 in the arc shape form a hole, and each brush 42 is provided with a linkage rod 45. Multiple linkage rods 45 pass through multiple arc-shaped guide grooves 431 respectively, so that multiple linkage rods 45 are rotatably connected to multiple connecting rods 44 respectively.

[0050] With this setup, once the turntable 43 rotates, the cleaning intensity of the pipe to be cleaned can be adjusted; for example, using... Figure 6 With the direction shown as a reference, the size of the hole formed by the multiple brushes 42 is at its smallest. Once the turntable 43 rotates counterclockwise, it will drive the multiple linkage rods 45 to move radially outward in the arc-shaped guide groove 431, thereby driving the multiple brushes 42 to move and rotate in a self-adaptive circumferential direction. This causes the multiple brushes 42 to separate from each other, thereby expanding the size of the hole formed by the multiple brushes 42. Therefore, this method allows the rotation of the turntable 43 to drive the multiple brushes 42 to shrink and expand the size of the hole they form, so as to adjust the cleaning force of the pipe to be cleaned.

[0051] To achieve the self-adaptive circumferential movement and rotation of the brush 42 mentioned above, such as Figures 2 to 7As shown, this embodiment of the cleaning mechanism 40 also includes a base 46, a rotating ring 47 and a transmission module 48, and the clamping area 41 includes a first clamping hole 411 and a second clamping hole 412 arranged opposite to each other. The first clamping hole 411 is provided on the base 46 and the second clamping hole 412 is provided on the turntable 43.

[0052] The base 46 is slidably mounted on the straight guide rail 11 and is driven by the drive mechanism 50 to slide. Therefore, the movement of the base 46 can drive the cleaning mechanism 40 to move as a whole, thereby meeting the back-and-forth cleaning needs of the pipe to be cleaned.

[0053] The rotating ring 47 is installed in the first clamping hole 411 in a rotatable manner, and multiple brushes 42 are rotatably mounted on the rotating ring 47. Therefore, once the turntable 43 rotates and applies a transmission force to the brushes 42, the transmission force will drive the rotating ring 47 to rotate in the first clamping hole 411, thereby realizing the circumferential movement of the brushes 42. The brushes 42 themselves only need to be rotatably connected to the rotating ring 47 by a rotating shaft to meet the requirement of the brushes 42 to achieve self-rotation.

[0054] The transmission module 48 engages with the teeth on the outer peripheral wall of the turntable 43. Through gear transmission, the transmission module 48 can be used to drive the turntable 43 to rotate, thereby providing driving force for the multiple brushes 42 to adjust the size of the hole.

[0055] In addition, to increase the cleaning area of ​​the pipes to be cleaned, this embodiment adopts... Figures 4 to 7 As shown, the base 46 has a cavity 461, through which the first clamping hole 411 passes, so that the base 46 forms a hollow structure with through-holes on both sides. A rotating ring 47 is also provided, including a first rotating ring 471 and a second rotating ring 472. The first rotating ring 471 is rotatably located on the side of the first clamping hole 411 adjacent to the turntable 43, and the second rotating ring 472 is rotatably located on the side of the first clamping hole 411 away from the turntable 43. Multiple brushes 42 are arranged in a perforated shape around the first clamping hole 411. A portion of the brushes 42 are rotatably mounted on the first rotating ring 471, and this portion of the brushes 42 is located between the base 46 and the turntable 43. Another portion of the brushes 42 are rotatably mounted on the second rotating ring 472, and this portion of the brushes 42 is located within the cavity 461.

[0056] With this configuration, multiple brushes 42 can be distributed along the length of the pipe to be cleaned, thereby expanding the coverage area of ​​the pipe to be cleaned and improving the cleaning efficiency of the pipe.

[0057] Furthermore, in order to achieve the purpose of the transmission module 48 providing driving force to the turntable 43, this embodiment employs, as follows: Figure 2 and Figure 3 The structure shown has a guide hole 17 in the wall of the chassis 10, which connects the inside and outside of the chassis 10. The transmission module 48 includes a transmission motor 481, a rack gear 482, and a transmission gear 483. The output end of the transmission motor 481 is connected to a corresponding gear to achieve meshing transmission with the rack gear 482. The rack gear 482 slides through the guide hole 17 and is coaxially connected with the transmission gear 483 inside the chassis 10. Since the radial dimension of the rack gear 482 matches the diameter of the guide hole 17, it can ensure that the rack gear 482 can pass through the guide hole 17 and move back and forth in a stable straight line. The transmission gear 483 meshes with the teeth on the turntable 43.

[0058] With this configuration, once the drive motor 481 starts working, it can drive the drive gear 483 to rotate, thereby driving the turntable 43 to rotate. Moreover, even when the cleaning mechanism 40 is moving back and forth, the strip gear 482 can also move back and forth, thus ensuring that the drive gear 483 always remains engaged with the turntable 43. That is, the turntable 43 can also remain rotating during the back and forth movement of the cleaning mechanism 40, so that the brush 42 can continuously clean the pipe to be cleaned.

[0059] Furthermore, to enhance the stability of the movement of the rack gear 482, such as... Figure 2 and Figure 3 As shown, in this embodiment, the transmission module 48 also includes a guide cover 484 disposed in the housing 10. The guide cover 484 is arranged along the moving trajectory of the cleaning mechanism 40, and a strip gear 482 is slidably installed inside the guide cover 484.

[0060] Because the guide cover 484 has a slotted tubular structure at its bottom, it can form a channel that matches the shape and size of the bar gear 482. This not only ensures the smooth movement of the bar gear 482 inside it, but also ensures that the bar gear 482 can always maintain engagement with the turntable 43 during its movement.

[0061] Regarding the drive mechanism 50, as Figure 2 and Figure 3As shown, the drive mechanism 50 is used to drive the cleaning mechanism 40 to move back and forth on the straight guide rail 11. Common cylinders, telescopic rods, linear motors, etc. can all achieve this function. However, in order to improve the efficiency of the repeated movement of the cleaning mechanism 40, this embodiment sets the drive mechanism 50 to include a drive motor 51 and a crank connecting rod 52. The output end of the drive motor 51 is rotatably connected to one end of the crank connecting rod 52, and the other end of the crank connecting rod 52 is rotatably connected to the cleaning mechanism 40. Therefore, when the drive motor 51 is working, it can drive the crank connecting rod 52 to swing back and forth, thereby realizing the reciprocating movement of the cleaning mechanism 40 on the straight guide rail 11.

[0062] Regarding the aforementioned camera 60, as Figure 3 and Figure 8 As shown, the camera 60 is mounted on the cleaning mechanism 40. The camera 60 is used to photograph fluorescent particles on the outer wall of the pipe to be cleaned. When the amount of fluorescent particles photographed exceeds a preset value, the outer pipe cleaning platform is used to control multiple brushes 42 to move toward the center of the pipe clamping hole.

[0063] Before cleaning, the nozzle 20 sprays fluorescent particles onto the pipe to be cleaned, then turns on the fluorescent lamp 30 and uses the camera 60 to capture and store the distribution of fluorescent particles on the pipe. Then, while cleaning the pipe, the camera 60 also captures images of the pipe. If the image comparison shows that the residual amount of fluorescent particles exceeds the preset value, indicating that the cleaning effect is not good, multiple brushes 42 will be driven to narrow the size of the holes they form, thereby increasing the cleaning power of the pipe.

[0064] Similarly, in addition to adjusting the size of the hole formed by the brush 42, if the amount of fluorescent particles exceeds the preset value, the cleaning mechanism 40 can be controlled to speed up its reciprocating movement, thereby further improving the cleaning efficiency of the pipe to be cleaned.

[0065] To ensure that the camera 60 can still clearly capture images of the pipes to be cleaned while the cleaning unit 40 is moving, such as... Figure 3 As shown, in this embodiment, the camera 60 is mounted on the base 46 and positioned on the side of the base 46 away from the turntable 43. The camera 60 is positioned with its shooting direction facing downwards to ensure that the shooting position of the camera 60 can always be aimed at the pipe to be cleaned.

[0066] In summary, the present invention has at least the following beneficial effects:

[0067] 1. Conformal bristle structure. Multiple bristles 42 are designed with a shutter-like structure, which improves the coverage of the object being cleaned. It has a strong conformal ability for pipe walls with cylindrical or polygonal cross-sections, which can significantly improve cleaning efficiency and cleaning versatility.

[0068] 2. Feedback Control System Adjustment. The camera 60 inside the chassis 10 captures images of the outer wall of the pipe, performs image processing and analysis to improve cleaning efficiency, and then adjusts the compression and movement speed of the brush 42. It can also analyze the cleaning efficiency under different cleaning modes (linear cleaning, rolling cleaning) to make decisions.

[0069] 3. Quantify cleaning efficiency. By capturing images with a 60° camera, the cleaning efficiency of the corresponding cleaning mode is obtained through image processing.

[0070] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
