Description

Technical Field

[0001] The present application relates to the technical field of pipeline inner wall cleaning, and in particular to a detachable industrial brush for pipeline inner wall cleaning. Background Art

[0002] Pipelines are usually used to transport liquids (water, oil, etc.) and gases (natural gas), etc. During the water transportation process, sand and gravel in the water may settle on the inner wall of the pipe, and impurities in the water may form moss on the inner wall of the pipe. In the long run, the water passing through the pipe will cause secondary pollution and affect the water quality. Therefore, in order to ensure that the water is not polluted for the second time, it is often necessary to clean the pipe regularly.

[0003] For example, the patent application with publication number CN210474870U provides a new type of industrial brush for pipe cleaning, which aims to solve the problem that the existing industrial brushes cannot clean the pipe deeply and can only clean part of the pipe mouth. On the other hand, they are greatly affected by the size of the inner diameter of the pipe, which wastes manpower and material resources, and has poor cleaning effect and low cleaning efficiency. The patent application includes a control box, a walking assembly device is installed on the annular outer wall of the control box, and a drive motor is built into the control box. The output end of the drive motor passes through the side wall of the mounting cover and is installed with a mounting plate, and the mounting plate is rotatably connected to the mounting cover. The other end of the mounting plate is detachably installed with a hollow brush roller by a plurality of fastening bolts, and a plurality of bundles of bristles are provided on the annular side wall of the hollow brush roller. The hollow brush roller is also provided with a dust suction assembly. The prior art is particularly suitable for efficient cleaning in pipes and has high social use value and application prospects.

[0004] However, the above-mentioned prior art still has some defects when cleaning the inner wall of the pipeline: 1. The above-mentioned prior art can clean some long straight pipelines, but when encountering a bend in the pipeline, due to the limitation of the control box and the length of the hollow brush roller, the prior art may not be able to cross the bend in the pipeline, thereby affecting the subsequent cleaning process of the pipeline.

[0005] 2. In the above-mentioned prior art, the inside of the pipe is cleaned only by the cooperation between the rotating hollow brush roller and the bristles, and some stubborn impurities attached to the inner wall of the pipe may not be completely cleaned, thereby affecting the cleaning effect of the prior art on the inner wall of the pipe.

DETAILED DESCRIPTION

[0041] The following is combined with Figures 1 to 8 This application is described in further detail.

[0042] The embodiment of the present application discloses a detachable industrial brush for cleaning the inner wall of a pipeline, which can be used to grind and remove impurities from the inner wall of the pipeline; at the same time, the brushes can be separated from each other to ensure that the brush can smoothly pass through the bends of the pipeline.

[0043] Embodiment 1:

[0044] See also Figure 1 and Figure 2 A detachable industrial brush for cleaning the inner wall of a pipe comprises a cylindrical block 1, a cleaning mechanism 2 is installed on the cylindrical block 1, a driving block 3 is also arranged on the side of the cylindrical block 1, a plurality of circumferentially evenly distributed moving wheels 4 are arranged on the circumferential surface of the driving block 3, an ejection mechanism 5 is installed between the cylindrical block 1 and the driving block 3, and a plurality of circumferentially evenly distributed moving wheels 6 are installed on the circumferential surface of the cylindrical block 1.

[0045] The cleaning mechanism 2 comprises: a plurality of fixed protrusions 21 which are arranged uniformly on the circumferential surface of the cylindrical block 1 , and each group of fixed protrusions 21 is symmetrically installed on the cylindrical block 1 along the axial direction of the cylindrical block 1 .

[0046] The cleaning roller 22 is arranged inside each set of fixed protrusions 21. The shaft head of the cleaning roller 22 is installed on the fixed protrusion 21 on the corresponding side through a bearing. The cleaning roller 22 can frictionally clean the stubborn impurities attached to the inner wall of the pipeline during its rotation.

[0047] The cleaning roller 22 can provide friction to the inner wall of the pipe during its rotation, so that the stubborn impurities attached to the inner wall of the pipe are subjected to external force, and the circumferential surface of the cleaning roller 22 can grind and clean the stubborn impurities attached to the inner wall of the pipe.

[0048] The ejection mechanism 5 includes: two telescopic spring rods 51 , which are symmetrically mounted on the driving round block 3 along the horizontal direction, and an annular plate 52 is commonly mounted on one end of the two telescopic spring rods 51 away from the driving round block 3 .

[0049] The driving assembly 53 is installed on the driving round block 3 and is used to pull the cylindrical block 1.

[0050] When the present invention encounters a bend in the pipeline, the driving component 53 releases the cylindrical block 1. At this time, the cylindrical block 1 moves along the pipeline and separates from the driving block 3, thereby separating the present invention into two sections, avoiding the possibility of collision or even jamming of the driving block 3 and the cylindrical block 1 when passing through the bend of the pipeline at the same time, thereby improving the practicality of the present invention in actual use.

[0051] Before the cleaning work begins, the cylindrical block 1 and the driving block are placed together inside the pipe to be cleaned, so that the moving wheel 1 4 and the moving wheel 2 6 are in contact with the inner wall of the pipe, and the moving wheel 1 4 is driven to move by an external motor (not shown in the figure). During the movement of the moving wheel 1 4, the driving round block 3 is driven to move, and then the driving round block 3 provides driving force to the cleaning mechanism 2 and the cylindrical block 1 during the movement of the inner wall of the pipe.

[0052] The moving wheel 1 4 can adaptively change the distance between it and the circumferential surface of the driving block 3, so that when the driving block 3 moves to the bend of the pipeline, the driving block 3 will not become loose or stuck due to the change in diameter at the bend.

[0053] See also Figure 2 An annular rack plate 521 is installed on the annular plate 52, and the shaft head of the cleaning roller 22 close to the annular plate 52 passes through the fixed protrusion 21 on the corresponding side. A gear 522 is installed on the shaft head of the cleaning roller 22 close to the annular plate 52, and a guiding inclined surface for guiding the annular rack plate 521 is provided on the gear teeth.

[0054] See also Figure 1 and Figure 3 The driving assembly 53 includes: two fixed connecting blocks 531, which are symmetrically installed in the horizontal direction on the side of the driving round block 3 away from the cylindrical block 1.

[0055] The winding shaft 532 is disposed between the two fixed connecting blocks 531 , and both ends of the winding shaft 532 are mounted on the fixed connecting blocks 531 on the corresponding side through bearings, and any end of the winding shaft 532 passes through the fixed connecting block 531 on the corresponding side.

[0056] The driving motor 533 is installed at one end of the winding shaft 532 that passes through the corresponding side fixed connecting block 531, and is used to drive the winding shaft 532 to rotate.

[0057] The traction rope 534 is wound around the winding shaft 532 , and one end of the traction rope 534 away from the winding shaft 532 passes through the driving round block 3 and the driving shaft 31 and is arranged on the connecting round block 33 .

[0058] During specific operation, after the driving round block 3 and the cylindrical block 1 are placed on the inner wall of the pipe, the driving motor 533 is started, and the output shaft of the driving motor 533 drives the winding shaft 532 to rotate. During the rotation of the winding shaft 532, the traction rope 534 is wound up. During the winding process of the traction rope 534, the cylindrical block 1 is driven to move toward the driving round block 3 on the inner wall of the pipe. During the movement of the cylindrical block 1, it is attached to the annular plate 52 and drives the annular plate 52 to move toward the driving round block 3. At this time, the telescopic spring rod 51 is in a compressed state, that is, the arc plate drives the cylindrical block 1 to have a tendency to move away from the driving round block 3.

[0059] During the movement of the cylindrical block 1, the gear 522 is driven to move synchronously. During the movement of the gear 522, the gear teeth are engaged with the inside of the annular rack plate 521, thereby ensuring that the gear 522 is meshed with the annular rack plate 521. The guide bevel can reduce the contact area between the gear teeth and the vertical surface of the annular rack plate 521, ensuring that the gear teeth will not collide with the annular rack plate 521 during the movement, thereby improving the meshing effect between the annular rack plate 521 and the gear teeth.

[0060] If the gear teeth have not yet meshed with the annular rack plate 521 , the driving block 3 is slightly rotated to drive the annular plate 52 to rotate a certain angle, and then the annular rack plate 521 can be driven to mesh with the gear 522 through the annular plate 52 .

[0061] See also Figure 3 and Figure 4 A driving shaft 31 is installed on the middle part of the driving block 3 close to the cylindrical block 1 through a bearing, and a driven shaft 32 is installed on the middle part of the cylindrical block 1 close to the driving block 3, and a connecting block 33 is installed on the end of the driven shaft 32 close to the driving shaft 31, and a plurality of circumferentially evenly distributed conical protrusions 34 are installed on the side of the connecting block 33 away from the driven shaft 32, and an annular rubber pad 35 matching the conical protrusions 34 is installed on the end of the driving shaft 31 away from the driving block 3.

[0062] During the movement of the cylindrical block 1 toward the driving block 3, the driven shaft 32 drives the connecting block to contact the annular rubber pad 35. At this time, the conical protrusion 34 is inserted into the annular rubber pad 35, that is, the driven shaft 32 and the driving shaft 31 are fixed by the cooperation of the connecting block 33, the annular rubber pad 35 and the conical protrusion 34. Then, during the rotation of the driving shaft 31 driven by an external drive (not shown in the figure), the driven shaft 32 rotates synchronously. During the rotation of the driven shaft 32, the cylindrical block 1 is synchronously driven to rotate. During the rotation of the cylindrical block 1, the cleaning roller 22 is driven to rotate circumferentially. During the circumferential rotation of the cleaning roller 22 around the cylindrical block 1, the gear 522 and the annular rack plate 521 are meshed with each other to drive the cleaning roller 22 to rotate. During the rotation of the cleaning roller 22, the stubborn impurities inside the pipeline can be polished, so as to remove the stubborn impurities on the inner wall of the pipeline.

[0063] At this time, the driving round block 3 cooperates with the driven shaft 31 and the driven shaft 32 to push the cylindrical block 1 to move on the inner wall of the pipe. During the movement of the cylindrical block 1 on the inner wall of the pipe, the cleaning roller 22 cleans the inner wall of the pipe.

[0064] The impurities produced by cleaning fall along the inner wall of the pipe to the bottom of the pipe.

[0065] See also Figure 4 The end of the connecting block 33 close to the driving shaft 31 is installed with a rotating block 331 through a bearing, and the end of the traction rope 534 away from the winding shaft 532 is installed on the rotating block 331.

[0066] After rotating a certain number of times, the traction rope 534 is twisted multiple times due to the rotation of the cylindrical block 1. At this time, the traction rope 534 changes from soft to hard. The rotating block 331 remains relatively still with the traction rope 534 during the rotation of the cylindrical block 1, thereby preventing the cylindrical block 1 from continuing to drive the traction rope 534 to continue to twist during the continued rotation, resulting in the possibility of the traction rope 534 being easily broken due to excessive twisting, thereby increasing the service life of the traction rope 534.

[0067] As the driving round block 3 moves on the inner wall of the pipeline, when the cylindrical block 1 moves to the bend of the pipeline, the driving motor 533 reverses and releases the traction rope 534. During the release of the traction rope 534, the telescopic spring rod 51 resets and drives the annular plate 52 to reset to the side away from the cylindrical block 1. During the reset of the annular plate 52, the cylindrical block 1 is ejected toward the bend of the pipeline and passes over the bend of the pipeline. After the cylindrical block 1 passes the bend of the pipeline, it will not continue to move due to inertia due to the restriction of the traction rope 534, thereby avoiding the cylindrical block 1 moving too far, resulting in areas on the inner wall of the pipeline that are missed from cleaning, thereby improving the comprehensiveness of the cleaning of the present invention.

[0068] See also Figure 3Since the telescopic spring rod 51 and the annular plate 52 are relatively large in size, in order to prevent the telescopic spring rod 51 from colliding with the annular plate 52 and the inner wall of the pipeline when the driving round block 3 passes over the bend of the pipeline, the present invention further provides a connecting rope 37 to compress and reduce the size of the telescopic spring rod 51. Specifically, rectangular blocks are symmetrically arranged in the horizontal direction on one side of the driving round block 3 close to the cylindrical block 1, and a collecting roller 36 is arranged between the two rectangular blocks. A connecting rope 37 is wound around the collecting roller 36, and the end of the connecting rope 37 away from the collecting roller 36 is installed on the annular plate 52.

[0069] Before the driving round block 3 passes over the bend of the pipeline, the collecting roller 36 is driven to rotate by an external drive (not shown in the figure). During the rotation of the collecting roller 36, the connecting rope 37 is reeled in. During the reeling of the connecting rope 37, the telescopic spring rod 51 is compressed through the annular plate 52. At this time, the lengths of the annular plate 52, the telescopic spring rod 51 and the driving round block 3 inside the pipeline are reduced, further reducing the possibility of the annular plate 52 colliding with the inner wall of the pipeline when the driving round block 3 passes over the bend of the pipeline.

[0070] When the cylindrical block 1 passes over the bend of the pipeline, the driving block 3 continues to pass over the bend of the pipeline. When the driving block 3 passes over the bend of the pipeline, the connecting rope 37 is loosened, and the annular plate 52 is reset. The above actions are repeated, and the driving block 3 and the cylindrical block 1 are reassembled to clean the remaining inside of the pipeline.

[0071] See also Figure 3 , an annular frame 38 is installed on the circumferential surface of the driving round block 3 and the circumferential surface of the cylindrical block 1, and an annular rubber sheet 384 is installed on the annular frame 38.

[0072] The annular frame 38 and the annular rubber sheet 384 cooperate with each other to drive the round block 3 and the cylindrical block 1 to be in a relatively closed state, so that the present invention can promptly drive the round block 3 to move in a relatively closed state during the cleaning process of the inner wall of the pipeline, avoiding the possibility of dust generated by grinding spreading inside the pipeline or even overflowing, thereby protecting the environment.

[0073] See also Figure 3 as well as Figure 6 A plurality of cleaning brushes 11 evenly distributed in the circumferential direction are installed on the circumferential surface of the cylindrical block 1 , and an annular brush 12 is installed on one side of the cleaning brushes 11 close to the driving round block 3 .

[0074] Multiple cleaning brushes 11 cooperate with each other to clean up stubborn impurities after grinding by the cleaning roller 22, avoiding the possibility of stubborn impurities after grinding adhering to the inner wall of the pipe; in order to avoid the problem of dead angles in the process of cleaning the inner wall of the pipe by the cleaning brush 11 and the cleaning roller 22, the annular brush 12 can also clean the inside of the pipe during the circumferential rotation of the cylindrical block 1, avoiding cleaning dead angles on the inner wall of the pipe, and further improving the cleaning effect of the inner wall of the pipe.

[0075] See also Figure 5 An elastic telescopic rod 13 corresponding to the second moving wheel 6 is installed on the circumferential surface of the cylindrical block 1. The second moving wheel 6 is a universal wheel and is installed on the end of the elastic telescopic rod 13 away from the cylindrical block 1.

[0076] The elastic telescopic rod 13 can ensure that the moving wheel 2 6 can adaptively change the distance between it and the circumferential surface of the cylindrical block 1, so that when the cylindrical block 1 moves to the bend of the pipeline, the cylindrical block 1 will not become loose or stuck due to the change in diameter of the bend, thereby ensuring that the cylindrical block 1 can smoothly pass the bend of the pipeline.

[0077] Replay Figure 2 A plurality of balls 14 evenly distributed in the circumferential direction are installed on one side of the cylindrical block 1 close to the driving round block 3 .

[0078] When the cylindrical block 1 and the annular plate 52 are pressed against and rotated, the balls 14 can reduce the friction between the cylindrical block 1 and the annular plate 52 and reduce the wear of the cylindrical block 1 on the annular plate 52 .

[0079] See also Figure 3 as well as Figure 7 In order to improve the use effect of the present invention inside the pipeline, the present invention also provides a central control component for controlling the start and stop of the drive motor 533. Specifically, a distance sensor 7 is installed on the side of the drive block 3 away from the cylindrical block 1, and the distance sensor 7 is electrically connected to the drive motor 533 through the central control component.

[0080] The central control assembly includes a central control panel installed on the cylindrical block 1, buttons set on the central control panel, and a central control unit set inside the central control panel, wherein the central control unit includes a central control module, a button control module electrically connected to the central control module, a motor control module electrically connected to the central control module, and a distance sensor module electrically connected to the central control module.

[0081] The button control module is electrically connected to the button, the motor control module is electrically connected to the driving motor 533 , and the distance sensor module is electrically connected to the distance sensor 7 .

[0082] During specific operation, turn on the button, the button control module receives the signal sent by the button and transmits the signal to the central control module. At this time, the central control module is turned on. When the driving round block 3 moves to the bend of the pipeline, the distance sensor 7 measures the distance of the driving round block 3 at this time and compares it with the actual set required displacement distance. If the two sets of data are consistent, the distance sensor 7 transmits the measured distance data to the distance sensing module. The distance sensing module transmits the signal obtained after processing the received distance data to the central control module. The central control module processes the received signal and transmits it to the motor control module. The motor control module transmits the processed signal to the drive motor 533. At this time, the drive motor 533 starts to reverse, driving the winding roller to reverse and release the traction rope 534, thereby realizing the self-start of the drive motor 533.

[0083] When the driving round block 3 passes the bend of the pipeline, the distance sensor 7 measures the distance of the driving round block 3 and compares it with the actual set displacement distance. If the two sets of data are consistent, the distance sensor 7 transmits the measured distance data to the distance sensing module. The distance sensing module transmits the signal obtained after processing the received distance data to the central control module. The central control module transmits the processed received signal to the motor control module. The motor control module transmits the processed signal to the driving motor 533. At this time, the driving motor 533 starts to rotate forward, driving the winding roller to rotate forward to wind the traction rope 534.

[0084] Embodiment 2:

[0085] Reference Figure 8 On the basis of the first embodiment, in order to further improve the cleaning effect of the inner wall of the pipeline, a plurality of evenly distributed air inlet pipes 381 are provided through the annular frame 38 near the driving block 3, and a transition pipe 382 is installed together at one end of the air inlet pipe 381 away from the driving block 3, and a dust suction pipe 383 is installed through the side of the annular frame 38 near the driving block 3 away from the transition pipe 382.

[0086] During specific operation, the air outlet of the existing air pump (not shown in the figure) is connected to the transition pipe 382, ​​and the dust suction port of the existing vacuum cleaner is connected to the dust suction pipe 383 through a lightweight hose. When the round block 3 is driven to move, the existing air pump and the existing vacuum cleaner are started, and the existing air pump pumps gas into the transition pipe 382. The gas flows into the air inlet pipe 381 through the transition pipe 382. The gas inside the air inlet pipe 381 forms an airflow and blows toward the inner wall of the pipe, and blows the impurities attached to the inner wall of the pipe, so that the impurities attached to the inner wall of the pipe fall to the bottom of the pipe, and then the impurities at the bottom of the pipe are dust-removed and adsorbed by the existing vacuum cleaner and the dust suction pipe 383, thereby ensuring the cleaning effect inside the pipe.

[0087] The implementation principle of the present invention is:

[0088] (1): Place the cylindrical block 1 and the driving block together inside the pipe to be cleaned, so that the moving wheel 1 4 and the moving wheel 2 6 are in contact with the inner wall of the pipe, and the moving wheel 1 4 is driven to move by an external motor, and the driving cylindrical block 3 is driven to move during the movement of the moving wheel 1 4.

[0089] (2): After the driving round block 3 and the cylindrical block 1 are placed on the inner wall of the pipe, the driving motor 533 is started. The output shaft of the driving motor 533 drives the winding shaft 532 to rotate. During the rotation of the winding shaft 532, the traction rope 534 is wound up. During the winding process of the traction rope 534, the cylindrical block 1 is driven to move toward the driving round block 3 on the inner wall of the pipe. During the movement of the cylindrical block 1, it is attached to the annular plate 52 and drives the annular plate 52 to move toward the driving round block 3.

[0090] (3): The cylindrical block 1 drives the cleaning roller 22 to rotate circumferentially during its rotation. The cleaning roller 22 rotates circumferentially around the cylindrical block 1 through the meshing of the gear 522 and the annular rack plate 521, driving the cleaning roller 22 to rotate on its own. During the self-rotation of the cleaning roller 22, the stubborn impurities inside the pipe can be polished.

[0091] (4): When the cylindrical block 1 moves to the bend of the pipeline, the driving motor 533 reverses and releases the traction rope 534. During the release of the traction rope 534, the telescopic spring rod 51 resets and drives the annular plate 52 to reset to the side away from the cylindrical block 1. During the reset of the annular plate 52, the cylindrical block 1 is ejected toward the bend of the pipeline and passes through the bend of the pipeline. After the cylindrical block 1 passes the bend of the pipeline, it will not continue to move due to inertia due to the restriction of the traction rope 534.

[0092] (5): Before the driving round block 3 passes over the bend of the pipeline, the collecting roller 36 is driven to rotate by an external drive (not shown in the figure). During the rotation of the collecting roller 36, the connecting rope 37 is reeled in. During the reeling of the connecting rope 37, the telescopic spring rod 51 is compressed by the annular plate 52. When the cylindrical block 1 passes over the bend of the pipeline, the driving round block 3 continues to pass over the bend of the pipeline. When the driving round block 3 passes over the bend of the pipeline, the connecting rope 37 is released. At this time, the annular plate 52 is reset, and the above-mentioned action is repeated. The driving round block 3 and the cylindrical block 1 are reassembled to clean the remaining inside of the pipeline.

[0093] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
