Description

Technical Field

[0001] The present invention relates to the technical field of drainage pipe blockage removal, and particularly to a pipe blockage removal device. Background Art

[0002] In the construction of modern urban infrastructure, the drainage pipe system, as the "underground blood vessels" of the city, undertakes the key function of discharging rainwater and sewage in a timely manner and ensuring the normal operation of the city. Drainage pipe blockage removal and silt cleaning operations, that is, by dredging the pipes and cleaning waste such as silt, to ensure the long-term smoothness of the pipes, play an irreplaceable role in preventing urban waterlogging, maintaining environmental hygiene, and ensuring the normal life of residents. If the pipes are not regularly dredged, it is extremely easy to cause problems such as sewage overflow and environmental pollution, seriously affecting the quality of life of urban residents and the urban ecological environment.

[0003] At present, for drainage pipes of different sizes, the common blockage removal methods mainly include direct high-pressure blockage removal and robot-assisted blockage removal. During direct high-pressure blockage removal operations, first, a high-pressure water truck is used to fill water into two inspection wells in sections, and then a dredger is used to stir and dilute the sludge in the pipe. Workers cooperate with machinery to continuously stir the sludge until it is fully dissolved in water. Finally, a sewage suction truck is used to suck out the sludge in the inspection well, and a small amount of remaining sludge is secondarily diluted by using a high-pressure water gun to impact the bottom of the well and then the suction is completed. For the robot-assisted blockage removal method, first, a robot is used to remove impurities on the pipe wall, and then high-pressure flushing is carried out. However, the currently used vehicle-mounted impurity cleaning robot has significant technical defects. It can only crush and clean impurities in front of the vehicle body and is difficult to reach the pipe wall above the robot, resulting in blind spots in pipe cleaning, and the integrity and thoroughness of the blockage removal operation are greatly limited, unable to meet the high-efficiency blockage removal requirements in complex pipe environments. Summary of the Invention

[0004] In view of this, the present invention provides a pipe blockage removal device to solve the problems existing in the above traditional blockage removal methods.

[0005] In a first aspect, the present invention provides a pipe blockage removal device, including:

[0006] A mounting frame;

[0007] An adjusting frame, including a first power member and a plurality of telescopic brackets; the first power member is constrained by the mounting frame and remains fixed, all the telescopic brackets are arranged circumferentially along the mounting frame and are all connected to the first power member, and all the telescopic brackets are configured to be driven by the first power member to extend outwards from the mounting frame or retract inwards towards the mounting frame;

[0008] A plurality of traveling wheels, and each telescopic bracket is provided with a traveling wheel at one end far from the first power member, and the traveling wheel is adapted to fit the inner wall of the pipe and move on the inner wall;

[0009] A plurality of blockage clearing components, each of the telescopic brackets is provided with the blockage clearing component at one end far away from the first power component. The blockage clearing component includes a support, a cleaning component and a second power component. The support is connected to the telescopic bracket, and the cleaning component is slidably arranged on the support;

[0010] The second power component is connected to the telescopic bracket, and the second power component is configured to drive the traveling wheels to rotate and simultaneously drive the cleaning component to slide relative to the support.

[0011] Beneficial effects: The mounting frame serves as the bracket of the pipeline blockage clearing device, and the adjusting frame is mounted thereon. The adjusting frame includes a first power component and a plurality of telescopic brackets. The first power component is constrained by the mounting frame and remains fixed. All the telescopic brackets are connected to the first power component, and the first power component is used to provide power for the telescopic brackets. In order to adapt to the shape of the pipeline, all the telescopic brackets are arranged circumferentially along the mounting frame. During use, the telescopic brackets are driven by the first power component to extend outward from the mounting frame so that the traveling wheels at the ends of the telescopic brackets are abutted against the inner wall of the pipeline; similarly, the telescopic brackets can also be driven by the first power component to retract inward from the mounting frame, and then the traveling wheels are retracted from the inner wall of the pipeline, so that it can adapt to the depths and diameters of different drainage pipelines and can comprehensively clean the circumferential side of the inner wall of the drainage pipeline. Each telescopic bracket is provided with a blockage clearing component at one end far away from the first power component. After the telescopic bracket is driven by the first power component to extend outward from the mounting frame, the blockage clearing component at the end of the telescopic bracket far away from the first power component is used to clean the side wall of the pipeline. Specifically, the blockage clearing component includes a support, a cleaning component and a second power component. The support is connected to the telescopic bracket and is used to provide support; the cleaning component is slidably arranged on the support, and the second power component is connected to the telescopic bracket. When cleaning the inner wall of the pipeline, the cleaning component is driven by the second power component to slide on the support so as to realize cleaning the inner wall of the pipeline by the cleaning component.

[0012] In an optional implementation manner, the blockage clearing component further includes:

[0013] A transmission component, which is arranged between the second power component and the cleaning component;

[0014] A reset component, which is arranged between the cleaning component and the support;

[0015] Wherein, the cleaning component has a connection position and a release position. At the connection position, the transmission component is connected to the cleaning component, and the transmission component is driven by the second power component to drive the cleaning component to move to the release position;

[0016] At the release position, the transmission component is separated from the cleaning component, and the cleaning component moves to the connection position under the action of the reset component.

[0017] Beneficial effects: By providing a transmission member and a reset member, the transmission member is disposed between the second power member and the cleaning member. The function of the transmission member is to transmit the power of the second power member to the cleaning member, enabling the second power member to drive the cleaning member to move. In the present invention, the cleaning member has a connection position and a release position. At the connection position, the transmission member is connected to the cleaning member. Thus, the second power member can transmit power to the cleaning member through the transmission member, enabling the cleaning member to slide on the support seat to clean the side wall of the pipeline. When the cleaning member slides on the support seat to the release position, the transmission member is separated from the cleaning member. At this time, the cleaning member is no longer restricted by the transmission member. By providing a reset member between the cleaning member and the support seat, during the process of the cleaning member being driven by the transmission member to move from the connection position to the release position, the reset member is compressed by the cleaning member to undergo elastic deformation. When the cleaning member slides on the support seat to the release position, the transmission member is separated from the cleaning member, and the cleaning member is no longer restricted by the transmission member and moves from the release position to the connection position under the action of the reset member. At the connection position, the cleaning member is connected to the transmission member again. Through the above method, the cleaning member can reciprocate between the connection position and the release position to clean the inner wall of the pipeline.

[0018] In an alternative embodiment, an arc-shaped groove is provided on the support seat, and the cleaning member is restricted to slide along the arc-shaped groove.

[0019] Beneficial effects: Since the inner wall of the pipeline is mostly arc-shaped, an arc-shaped groove is provided on the support seat, and a sliding block is provided on the cleaning member. The sliding block is restricted to slide along the arc-shaped groove, thereby restricting the movement trajectory of the cleaning member, enabling the cleaning member to better fit the inner wall of the pipeline during the cleaning process.

[0020] In an alternative embodiment, a limiting rod is provided in the arc-shaped groove along the direction of the arc-shaped groove, the reset member is provided on the limiting rod, and the reset member is restricted to undergo elastic deformation along the limiting rod.

[0021] Beneficial effects: In order to restrain the reset member, a limiting rod is provided in the arc-shaped groove along the direction of the arc-shaped groove, and the reset member is provided on the limiting rod. When the reset member is compressed by the cleaning member to undergo elastic deformation, the limiting rod can limit the reset member, enabling the reset member to always be within the arc-shaped groove, so that when the cleaning member loses the restriction of the transmission member, the reset member can still recover its deformation according to the initial position, thereby sending the cleaning member to the connection position.

[0022] In an alternative embodiment, the blockage clearing assembly further includes:

[0023] A rotating rod, connected between the second power member and the traveling wheel and transmitting power to the traveling wheel;

[0024] A connecting rod, one end of which is connected to the transmission member, and the other end of the connecting rod is coupled to the rotating rod. The connecting rod is configured to transmit power to the transmission member.

[0025] In an alternative embodiment, the blockage clearing assembly further includes a rack, and the rack is fixed to the cleaning member; the transmission member is a half gear;

[0026] At the connection position, the transmission member meshes with the rack and transmits power to the rack;

[0027] At the release position, the transmission member is separated from the rack.

[0028] In an alternative embodiment, two traveling wheels are provided at one end of any one of the telescopic brackets away from the first power member, and the traveling wheels are arranged in alignment along the moving direction of the pipeline blockage clearing device;

[0029] The pipeline blockage clearing device further includes a belt pulley and a power belt. The belt pulley is connected to the rotating rod, and the power belt is arranged on the belt pulley and the two traveling wheels.

[0030] In an alternative embodiment, the support is arc-shaped, and there is a gap between the supports in two adjacent blockage clearing assemblies.

[0031] In an alternative embodiment, a plurality of protrusions are provided on the outer side of the cleaning member, and the protrusions are adapted to contact the inner wall of the pipeline.

[0032] In an alternative embodiment, the telescopic bracket is slidably arranged in a through groove on the mounting bracket;

[0033] The adjusting bracket further includes a moving seat and a plurality of intermediate rods. The moving seat is connected to the first power member, and the intermediate rods are hinged between the moving seat and the telescopic bracket. The moving seat is configured to be driven by the first power member to drive the intermediate rods to move, and the intermediate rods drive the telescopic bracket to slide relative to the mounting bracket.

[0034] Beneficial effects: After the first power component is started, the output torque drives the moving seat to move axially along the mounting frame. The movement of the moving seat is converted into the radial sliding of the telescopic support through the hinge structure of the intermediate rod. Specifically, as the moving seat advances, the angle of the intermediate rod changes, pushing the telescopic support to extend outward along the through groove to the outside of the mounting frame until the traveling wheels are in close contact with the inner wall of the pipeline; when the telescopic support needs to be retracted, the first power component drives the moving seat in the reverse direction, and the intermediate rod pulls the telescopic support to retract inward into the mounting frame. Throughout the process, the intermediate rod plays a role in force transmission and direction conversion, ensuring that the telescopic movement of the telescopic support is accurate, stable, and can flexibly adjust the telescopic amount under the precise control of the first power component according to the change of the pipeline diameter. In actual application scenarios, whether it is the daily maintenance of urban drainage pipelines or dealing with sudden pipeline blockage accidents, this telescopic support drive structure can play an important role. Facing rainwater pipes and sewage pipes with different diameters, the device can quickly adjust the extended length of the telescopic support to ensure that the traveling wheels are in close contact with the inner wall of the pipeline, providing a stable working platform for the blockage removal component; when passing through pipeline bends or narrow areas, the flexible telescopic performance of the telescopic support enables the device to pass smoothly, avoiding jamming phenomena caused by changes in pipeline diameter or space limitations, and ensuring the continuity and high efficiency of the blockage removal operation.

Detailed implementation manners

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] In modern urban infrastructure construction, the drainage pipeline system, as the "underground blood vessels" of the city, undertakes the key function of timely discharging rainwater and sewage and ensuring the normal operation of the city. Drainage pipeline blockage removal and dredging operations, that is, by dredging pipelines and cleaning wastes such as silt, ensure the long-term smoothness of pipelines, and play an irreplaceable role in preventing urban waterlogging, maintaining environmental sanitation, and ensuring the normal life of residents. If the pipelines are not regularly dredged, it is extremely easy to cause problems such as sewage overflow and environmental pollution, seriously affecting the quality of life of urban residents and the urban ecological environment.

[0046] At present, for drainage pipelines of different sizes, common blockage removal methods mainly include direct high-pressure blockage removal and robot-assisted blockage removal. During direct high-pressure blockage removal operations, first, a high-pressure water truck is used to fill water into two inspection wells in sections, and then a dredger is used to stir and dilute the sludge in the pipeline. Workers cooperate with machinery to continuously stir the silt until it is fully dissolved in water. Finally, a sewage suction truck is used to suck out the silt in the inspection well, and a small amount of remaining silt is secondarily diluted by using a high-pressure water gun to impact the bottom of the well and then the suction is completed. For the robot-assisted blockage removal method, first, a robot is used to remove impurities on the pipe wall, and then high-pressure flushing is carried out. However, the currently used vehicle-mounted impurity removal robot has significant technical defects. It can only crush and clean the impurities in front of the vehicle body and is difficult to reach the pipe wall above the robot, resulting in blind spots in pipeline cleaning, and the integrity and thoroughness of blockage removal operations are greatly limited, unable to meet the high-efficiency blockage removal requirements in complex pipeline environments.

[0047] To this end, this embodiment provides a pipeline blockage clearing device to solve the above problems.

[0048] The following combines Figures 1 to 5 to describe the embodiments of the present invention.

[0049] According to an embodiment of the present invention, there is provided a pipeline blockage clearing device, including a mounting frame 1, an adjusting frame 2, four sets of traveling wheels 3, and four sets of blockage clearing components 4. The adjusting frame 2 includes a first power member 21 and a plurality of telescopic brackets 22; the first power member 21 is constrained by the mounting frame 1 and remains fixed. All the telescopic brackets 22 are arranged circumferentially along the mounting frame 1 and are all connected to the first power member 21. All the telescopic brackets 22 are configured to be driven by the first power member 21 to extend outward from the mounting frame 1 or retract inward toward the mounting frame 1; one end of any telescopic bracket 22 away from the first power member 21 is provided with a traveling wheel 3, and the traveling wheel 3 is adapted to fit the inner wall of the pipeline and move on the inner wall; one end of any telescopic bracket 22 away from the first power member 21 is provided with a blockage clearing component 4. The blockage clearing component 4 includes a support 41, a cleaning member 42, and a second power member 43. The support 41 is connected to the telescopic bracket 22, and the cleaning member 42 is slidably arranged on the support 41; the second power member 43 is connected to the telescopic bracket 22, and the second power member 43 is configured to drive the traveling wheel 3 to rotate and at the same time drive the cleaning member 42 to slide relative to the support 41.

[0050] The mounting frame 1 serves as the support of the pipeline blockage clearing device, on which the adjusting frame 2 is mounted. The adjusting frame 2 includes a first power member 21 and a plurality of telescopic brackets 22. The first power member 21 is constrained by the mounting frame 1 and remains fixed. All the telescopic brackets 22 are connected to the first power member 21, and the first power member 21 is used to provide power for the telescopic brackets 22. In order to adapt to the shape of the pipeline, all the telescopic brackets 22 are arranged circumferentially along the mounting frame 1. During use, the telescopic brackets 22 are driven by the first power member 21 to extend outward from the mounting frame 1 so that the traveling wheels 3 at the ends of the telescopic brackets 22 are abutted against the inner wall of the pipeline; similarly, the telescopic brackets 22 can also be driven by the first power member 21 to retract inward toward the mounting frame 1, and then the traveling wheels 3 are retracted from the inner wall of the pipeline. One end of any telescopic bracket 22 away from the first power member 21 is provided with a blockage clearing component 4. After the telescopic bracket 22 is driven by the first power member 21 to extend outward from the mounting frame 1, the blockage clearing component 4 at the end of the telescopic bracket 22 away from the first power member 21 is used to clean the side wall of the pipeline. Specifically, the blockage clearing component 4 includes a support 41, a cleaning member 42, and a second power member 43. The support 41 is connected to the telescopic bracket 22, and the support 41 is used to provide support; the cleaning member 42 is slidably arranged on the support 41, and the second power member 43 is connected to the telescopic bracket 22. When cleaning the inner wall of the pipeline, the cleaning member 42 is driven by the second power member 43 to slide on the support 41 to realize cleaning the inner wall of the pipeline by the cleaning member 42.

[0051] In one embodiment, as Figure 1 shown, the mounting bracket 1 is annular, the first power member 21 is disposed in the middle of the mounting bracket 1, one end of the telescopic bracket 22 is located in the middle of the mounting bracket 1 and is connected to the first power member 21, and the other end of the telescopic bracket 22 passes through the through hole on the mounting bracket 1 and extends out of the mounting bracket 1. The traveling wheel 3 is installed at the end of the telescopic bracket 22 extending out of the mounting bracket 1. It can be understood that in order to avoid interference of the blockage clearing assembly 4 with the operation of the traveling wheel 3, the traveling wheel 3 is located outside the blockage clearing assembly 4, so that the traveling wheel 3 can be in contact with the side wall of the pipeline, and the blockage clearing assembly 4 can also clean the side wall of the pipeline. Alternatively, the traveling wheel 3 can also be flush with the blockage clearing assembly 4. During operation, the traveling wheel 3 moves in the front or rear direction of the blockage clearing assembly 4, and the blockage clearing assembly 4 can also clean the side wall of the pipeline without interfering with the traveling wheel 3.

[0052] In one embodiment, the blockage clearing assembly 4 further includes a transmission member 44 and a reset member 45. The transmission member 44 is disposed between the second power member 43 and the cleaning member 42; the reset member 45 is disposed between the cleaning member 42 and the support 41; wherein, the cleaning member 42 has a connection position and a release position. At the connection position, the transmission member 44 is connected to the cleaning member 42, and the transmission member 44 is driven by the second power member 43 to drive the cleaning member 42 to move to the release position; at the release position, the transmission member 44 is separated from the cleaning member 42, and the cleaning member 42 moves to the connection position under the action of the reset member 45.

[0053] In the above embodiments, by providing a transmission member 44 and a reset member 45, the transmission member 44 is disposed between the second power member 43 and the cleaning member 42. The function of the transmission member 44 is to transmit the power of the second power member 43 to the cleaning member 42, so that the second power member 43 can drive the cleaning member 42 to move. In this embodiment, the cleaning member 42 has a connection position and a release position. At the connection position, the transmission member 44 is connected to the cleaning member 42. Further, the second power member 43 can transmit power to the cleaning member 42 through the transmission member 44, so that the cleaning member 42 can slide on the support 41 to clean the side wall of the pipeline. When the cleaning member 42 slides on the support 41 to the release position, the transmission member 44 is separated from the cleaning member 42. At this time, the cleaning member 42 is no longer restricted by the transmission member 44. By providing the reset member 45 between the cleaning member 42 and the support 41, during the process that the cleaning member 42 is driven by the transmission member 44 to move from the connection position to the release position, the reset member 45 is compressed by the cleaning member 42 to undergo elastic deformation. When the cleaning member 42 slides on the support 41 to the release position, the transmission member 44 is separated from the cleaning member 42. The cleaning member 42 is no longer restricted by the transmission member 44 and moves from the release position to the connection position under the action of the reset member 45. At the connection position, the cleaning member 42 is connected to the transmission member 44 again. Through the above method, the cleaning member 42 can reciprocate between the connection position and the release position to clean the inner wall of the pipeline.

[0054] In one embodiment, as Figure 3 shown, the blockage clearing assembly 4 further includes a rack 410, and the rack 410 is fixed to the cleaning member 42; the transmission member 44 is a half gear; at the connection position, the transmission member 44 meshes with the rack 410 and transmits power to the rack 410; at the release position, the transmission member 44 is separated from the rack 410.

[0055] In the above embodiments, a rack 410 is fixed to the cleaning member 42, and the transmission member 44 is a half gear. The transmission member 44 is used to mesh with the rack 410. At Figure 3 the shown connection position, the transmission member 44 meshes with the rack 410 and transmits power to the rack 410. Specifically, the transmission member 44 rotates under the action of the second power member 43, and then meshes with the rack 410 through the teeth on the transmission member 44 to drive the cleaning member 42 to slide on the support 41 until when it moves from the connection position to the release position, the transmission member 44 reaches the part without teeth, and the transmission member 44 is separated from the rack 410. After the cleaning member 42 loses the restraint of the transmission member 44, it moves from the release position to the connection position under the action of the reset member 45. When the transmission member 44 rotates again until the part with teeth reaches the rack 410 and meshes with the rack 410, it drives the cleaning member 42 to move to the release position again.

[0056] In one embodiment, as Figure 4 andFigure 5 As shown in the figure, an arc-shaped groove 46 is provided on the support 41, and the cleaning member 42 is restricted to slide along the arc-shaped groove 46. Since most of the inner walls of the pipeline are arc-shaped, an arc-shaped groove 46 is provided on the support 41, and a sliding block is provided on the cleaning member 42. The sliding block is restricted to slide along the arc-shaped groove 46, thereby restricting the movement track of the cleaning member 42, so that during the cleaning process, the cleaning member 42 can better fit the inner wall of the pipeline and move.

[0057] In one embodiment, as Figure 4 and Figure 5 shown, a limiting rod 47 arranged along the direction of the arc-shaped groove 46 is provided in the arc-shaped groove 46, a reset member 45 is arranged on the limiting rod 47, and the reset member 45 is restricted to elastically deform along the limiting rod 47.

[0058] In the above embodiment, in order to restrain the reset member 45, a limiting rod 47 arranged along the direction of the arc-shaped groove 46 is provided in the arc-shaped groove 46, and the reset member 45 is arranged on the limiting rod 47. When the reset member 45 is compressed by the cleaning member 42 and elastically deformed, the limiting rod 47 can limit the reset member 45, so that the reset member 45 can always be in the arc-shaped groove 46, so that when the cleaning member 42 loses the restriction of the transmission member 44, the reset member 45 can still recover and deform according to the initial position, and then send the cleaning member 42 to the connection position. Specifically, the reset member 45 is a spring.

[0059] In one embodiment, as Figure 2 and Figure 3 shown, the blockage clearing assembly 4 further includes a rotating rod 48 and a connecting rod 49. The rotating rod 48 is connected between the second power member 43 and the traveling wheel 3 and transmits power to the traveling wheel 3; one end of the connecting rod 49 is connected to the transmission member 44, and the other end of the connecting rod 49 is coupled to the rotating rod 48. The connecting rod 49 is configured to transmit power to the transmission member 44. When the second power member 43 is started, the power is transmitted to the rotating rod 48 through the output shaft. The rotating rod 48 serves as a power transfer component and starts to rotate at a high speed, and transmits the power to the traveling wheel 3, thereby driving the traveling wheel 3 to rotate, so that the entire pipeline blockage clearing device can move smoothly in the pipeline. At the same time, the rotation of the rotating rod 48 will also drive the connecting rod 49 coupled thereto to move. The connecting rod 49 drives the transmission member 44 connected thereto to rotate. The transmission member 44 is specifically a half gear, so as to achieve the above-mentioned meshing of the teeth on the transmission member 44 with the rack 410, driving the cleaning member 42 to slide on the support 41. When the cleaning member 42 moves from the connection position to the release position, the transmission member 44 reaches the part without teeth, and the transmission member 44 is separated from the rack 410. After the cleaning member 42 loses the restraint of the transmission member 44, under the action of the reset member 45, it moves from the release position to the connection position. When the part of the transmission member 44 with teeth reaches the rack 410 again and meshes with the rack 410, it drives the cleaning member 42 to move to the release position again.

[0060] In one embodiment, Figure 2 and Figure 3 As shown, a worm 415 is provided on the rotating rod 48, and a turbine 414 is provided at the end of the connecting rod 49. Through the cooperation between the turbine 414 and the worm 415, the power on the rotating rod 48 is transmitted to the connecting rod 49.

[0061] In one embodiment, the support 41 is in an arc shape, and a gap is provided between the supports 41 in two adjacent clearing assemblies 4. The arc-shaped shape matches the contour of the inner wall of the pipe, so that the clearing assembly 4 can fit the side wall of the pipe more closely, and the cleaning member 42 can reduce the cleaning blind area caused by distance deviation when working, and significantly improve the clearing effect. Taking a circular drainage pipe as an example, the arc-shaped support 41 can ensure that the cleaning member 42 always maintains the best contact angle with the pipe wall, and both hard dirt and soft sludge can be cleaned more efficiently. In actual application scenarios, for pipeline systems with large changes in pipe diameter, this type of arc-shaped support 41 with intervals is set. When entering pipe sections with different pipe diameters, the telescopic bracket 22 adjusts the spacing, and each support 41 can flexibly adapt to changes in pipe diameter, and always maintain a reasonable distribution state and working distance.

[0062] In one embodiment, a plurality of protrusions 413 are provided on the outside of the cleaning member 42. When the cleaning member 42 is driven by the transmission member 44 to clean the inner wall of the pipeline, the protrusions 413 first contact the obstruction. Under the action of the power, the sharp head of the protrusion 413 quickly penetrates into the obstruction, and then the sliding of the cleaning member 42 causes the protrusion 413 to generate a lateral shear force on the obstruction, breaking or peeling it. For obstructions such as soft silt, the surface texture of the protrusion 413 can increase the friction between the protrusion 413 and the silt, and the silt is effectively scraped off and carried to the downstream of the pipeline during the sliding process of the cleaning member 42, and discharged from the pipeline through the water flow.

[0063] In one embodiment, Figure 6 As shown, any telescopic bracket 22 is provided with two running wheels 3 at one end away from the first power member 21, and the running wheels 3 move along the moving direction of the pipeline clearing device ( Figure 6 The pipeline clearing device also includes a pulley 411 and a power belt 412, the pulley 411 is connected to the rotating rod 48, and the power belt 412 is arranged on the pulley 411 and the two running wheels 3. Two running wheels 3 aligned along the moving direction of the pipeline clearing device are arranged at one end of any telescopic bracket 22 away from the first power member 21. This design improves the stability of the device moving in the pipeline. When the second power member 43 is started, the rotating rod 48 is driven to rotate, and the pulley 411 connected to the rotating rod 48 rotates accordingly. Since the power belt 412 is tightly mounted on the pulley 411 and the running wheel 3, the rotation of the pulley 411 drives the power belt 412 to run through the friction force, thereby driving the two running wheels 3 to rotate synchronously.

[0064] In one embodiment, as Figure 2 shown, the telescopic bracket 22 is slidably arranged in the through groove on the mounting bracket 1; the adjusting bracket 2 further includes a moving seat 23 and a plurality of intermediate rods 24. The moving seat 23 is connected to the first power member 21, and the intermediate rods 24 are hinged between the moving seat 23 and the telescopic bracket 22. The moving seat 23 is configured to be driven by the first power member 21 to drive the intermediate rods 24 to move, and the intermediate rods 24 drive the telescopic bracket 22 to slide relative to the mounting bracket 1. When the first power member 21 is started, the output torque drives the moving seat 23 to move axially along the mounting bracket 1. The movement of the moving seat 23 is converted into the radial sliding of the telescopic bracket 22 through the hinge structure of the intermediate rods 24. Specifically, as the moving seat 23 advances, the angle of the intermediate rods 24 changes, pushing the telescopic bracket 22 to extend outward along the through groove towards the outside of the mounting bracket 1 until the traveling wheels 3 are in close contact with the inner wall of the pipeline; when the telescopic bracket 22 needs to be retracted, the first power member 21 drives the moving seat 23 in the reverse direction, and the intermediate rods 24 pull the telescopic bracket 22 to retract towards the inside of the mounting bracket 1. Throughout the process, the intermediate rods 24 play a role in force transmission and direction conversion, ensuring that the telescopic movement of the telescopic bracket 22 is accurate and stable, and can flexibly adjust the telescopic amount under the precise control of the first power member 21 according to the change of the pipeline diameter. In the actual application scenario, whether it is the daily maintenance of urban drainage pipelines or the handling of sudden pipeline blockage accidents, the driving structure of the telescopic bracket 22 can play an important role. Facing rainwater pipes and sewage pipes with different diameters, the device can quickly adjust the extended length of the telescopic bracket 22 to ensure that the traveling wheels 3 are in close contact with the inner wall of the pipeline, providing a stable working platform for the blockage removal component 4; when passing through pipeline bends or narrow areas, the flexible telescopic performance of the telescopic bracket 22 enables the device to pass smoothly, avoiding jamming caused by diameter changes or space limitations, and ensuring the continuity and high efficiency of the blockage removal operation.

[0065] In one embodiment, as Figure 4 shown, protective plates 5 are arranged on both sides of the mounting bracket 1 to protect the first power member 21, the moving seat 23 and a plurality of intermediate rods 24 inside the mounting bracket 1. During the actual operation of the pipeline blockage removal device, the internal core components are vulnerable to the erosion and impact of sewage, silt and debris in the pipeline. To further improve the reliability and service life of the device, as Figure 4As shown, protective plates 5 are provided on both sides of the mounting frame 1. This design constructs a protective barrier for the first power member 21, the movable seat 23 and the plurality of intermediate rods 24 inside the mounting frame 1. Furthermore, the telescopic bracket 22 is inserted into the through groove of the mounting frame 1, and a sealing strip can also be provided in the through groove of the mounting frame 1 to protect the first power member 21, the movable seat 23 and the plurality of intermediate rods 24 inside the mounting frame 1. When the telescopic bracket 22 slides in the through groove, the elastic deformation of the sealing strip can always maintain close contact with the surface of the telescopic bracket 22 to form a dynamic seal. Even under complex working conditions such as water flow impact in the pipeline and device vibration, the lip structure of the sealing strip can effectively block the penetration of sewage and silt, prevent it from entering the interior of the mounting frame 1, and cause damage to core components such as the first power member 21 and the movable seat 23. Among them, the first power member 21 can be fixed on the protective plate 5.

[0066] In one embodiment, Figure 2 As shown, a waterproof box 416 is provided outside the second power member 43 (for the convenience of explanation, part of the waterproof box 416 is not closed in the figure) to protect the second power member 43. In this embodiment, the first power member 21 and the second power member 43 are both motors. In order to be suitable for the use environment, they can use existing waterproof motors and related supporting facilities.

[0067] A specific implementation of the pipeline blockage clearing device provided in this embodiment is as follows:

[0068] Start the first power member 21, which is connected to the moving seat 23 through a screw rod. When the moving seat 23 moves up and down along the screw rod, it can push or pull the intermediate rod 24 and the telescopic bracket 22 to adjust the position of the telescopic bracket 22 so that the walking wheel 3 on the telescopic bracket 22 overlaps the inner wall of the pipe.

[0069] The second power member 43 is started, and the power is transmitted to the rotating rod 48 through the output shaft. The rotating rod 48 transmits the power to the running wheel 3, thereby driving the running wheel 3 to rotate, so that the entire pipeline clearing device can move smoothly in the pipeline. At the same time, the rotation of the rotating rod 48 will also drive the connecting rod 49 coupled to it to rotate. The connecting rod 49 drives the transmission member 44 connected to it to rotate. The transmission member 44 is specifically a half gear. The teeth on the transmission member 44 are meshed with the rack 410, driving the cleaning member 42 to slide on the support 41 until it moves from the connection position to the release position. The transmission member 44 reaches the part without teeth, and the transmission member 44 is separated from the rack 410. After the cleaning member 42 loses the constraint of the transmission member 44, it moves from the release position to the connection position under the action of the reset member 45. When the transmission member 44 rotates again until the toothed part reaches the rack 410 and meshes with the rack 410, it drives the cleaning member 42 to move to the release position again, thereby crushing impurities at various places in the pipeline.
