Description

A dredging robot for pipeline dredging. Technical Field

[0001] This invention relates to the field of dredging technology, specifically to a dredging equipment for a pipeline dredging robot. Background Technology

[0002] Drainage pipes refer to the drainage system consisting of pipes and their ancillary facilities that collect and discharge domestic sewage, wastewater, and rainwater. They are an indispensable water conservancy project in modern cities. However, due to the high usage rate of drainage pipes, a lot of dirt often accumulates inside, which can easily cause pipe blockage and poor drainage, affecting the normal operation of the urban drainage system. Moreover, the inside of the pipes is dark and damp and contains a variety of toxic gases. Manual dredging is labor-intensive, has extremely poor dredging effect, and poses a threat to the life safety of workers. Therefore, pipe dredging equipment is needed to replace manual dredging.

[0003] However, during the process of cleaning sludge or debris from pipes, the accumulation of sludge on the drill bit can significantly reduce the efficiency of the drill bit's work. In addition, some sludge and debris may become hard due to external factors and adhere to the inner wall of the pipe, making them very difficult to clean. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a dredging and cleaning device for a pipeline dredging robot, comprising a circuit opener, a cleaner, a mover, and a water tank, wherein the end face of the circuit opener is fixedly connected to the cleaner, the end of the cleaner away from the circuit opener is sleeved on the inner wall of the mover, and the end of the mover away from the cleaner is fixedly connected to the water tank.

[0005] The circuit opener includes a drive motor, the shaftless end of which is fixedly connected to the cleaner, and the output end of the drive motor is connected to a main shaft via a coupling. A bearing is interference-fitted on the outer side of the main shaft, and a seat block is fixedly connected to the outer side of the bearing.

[0006] A top plate is fixedly connected to the top of the main shaft, and a drill bit is fixedly connected to the outer side of the top plate. A bottom sleeve is rotatably connected to the bottom of the drill bit, and the bottom of the bottom sleeve is fixedly connected to the drive motor. An anti-clogging device is slidably installed inside the drill bit. When the drive motor is started, the main shaft connected to it via a coupling will rotate in the forward direction. As a result, the top plate fixed to the top of the main shaft will rotate, which in turn will drive the drill bit fixed to its outer side to rotate, thereby achieving the function of rotating and clearing the silt or debris accumulated inside the pipe.

[0007] The cleaner includes a cleaning plate, an external rod fixedly connected to the bottom of the cleaning plate, a deflection rod fixedly connected to the end of the external rod away from the cleaning plate, a fixed seat provided at the end of the deflection rod away from the external rod, and clamping plates fixedly connected to both the upper and lower sides of the fixed seat. The inner side of the clamping plates is rotatably connected to the deflection rod. The rotation of the deflection rod is used to achieve the contact relationship between the cleaning plate and the inner wall of the pipe, so as to appropriately adjust the cleaning plate for pipes of different sizes and the viscosity of dirt on the inner wall of the pipe.

[0008] The mobile device includes a housing, one end of which is sleeved with a cleaner, and the end of the housing away from the cleaner is fixedly connected to a water tank. A squeezing sleeve is provided inside the housing, and the end face of the squeezing sleeve is fixedly connected to the cleaner. An airbag is provided on the side of the squeezing sleeve away from the cleaner, and the airbag is fixedly installed inside the housing.

[0009] Preferably, the anti-blocking device includes a connecting piece, the top of which is fixedly connected to a top plate, a hollow plate is fixedly connected to the outer side of the connecting piece, a float is slidably installed on the inner side of the hollow plate, and an extension block is inserted into the outer end of the float.

[0010] Preferably, springs are symmetrically arranged on both sides of the float, one end of each spring is fixedly connected to the extension block, and the end of the spring away from the extension block is fixedly connected to the hollow plate. The springs are always in a taut state, thus serving to return and limit the extension block's position. The limiting function prevents the extension block from slipping out or falling off from the drill bit during the return process.

[0011] Preferably, a draining strip is fixedly connected to the end of the extension block away from the spring, and the extension block is slidably installed inside the drill bit. During rotation, the float impacts the seat block, then the float moves in the opposite direction into the extension block and applies reverse pressure. The extension block then moves outward from the drill bit, causing the draining strip fixed to its other end to move outward as well. The draining strip then cleans the threaded curve holes on the drill bit surface of silt or debris, preventing the accumulation of silt or debris that could affect the drill bit's operating efficiency.

[0012] Preferably, a triangular plate is fixedly connected to the bottom of the clamping piece, and a slotted shell is slidably installed on the outer side of the triangular plate. One end of the slotted shell is fixedly connected to the drive motor, and the end of the slotted shell away from the drive motor is sleeved on the inner wall of the outer shell. A fixing ring is fixedly connected to the outer side of the slotted shell.

[0013] Preferably, a side plate is fixedly connected to the inner side of the fixing ring, a threaded rod is threadedly connected to the inner side of the side plate, and a pull rod is fixedly connected to the inner side of the fixing ring.

[0014] Preferably, the end of the pull rod away from the fixed ring is fixedly connected to the outer rod, and the pull rod and the side plate are fixed to the fixed ring in a staggered circumferential manner. The other end of the deflection rod is connected to the outer rod, so when the clamping plate moves forward, the deflection rod will rotate clockwise. The reason for the rotation of the deflection rod is that the cleaning plate has already been placed inside the pipe, and the outer rod is bent, so the cleaning plate is squeezed and adapted to the inner wall of the pipe.

[0015] Preferably, a ventilation rod is fixedly connected to the outer side of the airbag, an external connecting strip is fixedly connected to the end of the ventilation rod away from the airbag, a moving block is fixedly connected to the inner end of the external connecting strip, and a support plate is provided on the outer side of the moving block.

[0016] Preferably, a sliding groove is provided on the inner side of the support plate, the moving block is slidably installed inside the sliding groove, and a bent rod is slidably installed on the inner side of the sliding groove, with both ends of the bent rod fixedly connected to the outer shell.

[0017] Preferably, a connecting ring is fixedly connected to the outer end of the outer strip, an anti-fouling block is fixedly connected to the top of the connecting ring, a diverter plate is fixedly connected to the top of the anti-fouling block, and a protective wheel is provided on the outer side of the diverter plate. The other end of the outer strip is connected to the connecting ring, and an anti-fouling block is fixedly connected to the top of the connecting ring. The upward-moving anti-fouling block serves to protect the protective wheel and prevent it from being contaminated.

[0018] Preferably, the protective wheel is rotatably mounted on the inner side of the support plate, and a limiting plate is slidably mounted on the outer side of the support plate. The end face of the limiting plate is fixedly connected to the anti-fouling block. The diversion plate fixedly connected to the top of the anti-fouling block serves to divert and discharge the dirt or debris removed by the cleaner to the left and right, while preventing dirt from flowing into the interior of the protective wheel or the transition point, thus preventing the protective wheel from getting stuck.

[0019] This invention provides a dredging and cleaning device for pipelines using a robotic dredging system. It offers the following advantages:

[0020] I. The dredging equipment of this pipeline dredging robot uses a float that impacts the base block during rotation. The float then moves in the opposite direction into the extension block and squeezes it in the opposite direction. The extension block then moves outward from the inside of the drill bit, driving the dredging strip fixed to its other end to move outward. At this time, the dredging strip cleans the silt or debris from the threaded curve hole on the surface of the drill bit, preventing the accumulation of silt or debris from affecting the drilling efficiency.

[0021] 2. The dredging equipment of this pipeline dredging robot is connected to an external rod at the other end of the deflection rod. Therefore, when the clamping plate moves forward, the deflection rod will rotate clockwise. The reason for the rotation of the deflection rod is that the cleaning plate has been placed inside the pipeline beforehand, and the external rod is bent, so the cleaning plate is squeezed and adapted to the inner wall of the pipeline.

[0022] Third, the dredging equipment of this pipeline dredging robot increases the bending effect of the external rod by rotating the deflector rod, and prevents the cleaning plate from being squeezed against the inner wall of the pipeline. The rotation of the deflector rod is used to achieve the contact relationship between the cleaning plate and the inner wall of the pipeline, so as to appropriately adjust the cleaning plate according to the different sizes of pipelines and the viscosity of the dirt on the inner wall of the pipeline.

[0023] Fourth, the dredging equipment of this pipeline dredging robot, through the diversion plate fixedly connected to the top of the anti-fouling block, plays the role of diverting the dirt or debris removed by the former cleaner to the left and right, while preventing dirt from flowing into the interior of the protective wheel or the transition point, causing problems such as the protective wheel getting stuck.

[0024] 5. The dredging equipment of this pipeline dredging robot, by continuing to squeeze the airbag, will eventually squeeze the support plate. At this time, the support plate will move upward along the curved rod. Therefore, the protective wheel installed on the inner side of the support plate will also move upward, thus enabling it to move pipelines of different sizes. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0035] The first embodiment, as shown in Figures 1-3, provides a technical solution: a dredging and cleaning device for a pipeline dredging robot, comprising a circuit opener 1, a cleaner 2, a mover 3, and a water tank 4. The end face of the circuit opener 1 is fixedly connected to the cleaner 2. The end of the cleaner 2 away from the circuit opener 1 is sleeved on the inner wall of the mover 3. The end of the mover 3 away from the cleaner 2 is fixedly connected to the water tank 4.

[0036] The circuit opener 1 includes a drive motor 11. The shaftless end of the drive motor 11 is fixedly connected to the cleaner 2. The output end of the drive motor 11 is connected to a main shaft 12 via a coupling. A bearing 13 is interference-fitted to the outer side of the main shaft 12. A seat block 16 is fixedly connected to the outer side of the bearing 13. A top plate 14 is fixedly connected to the top of the main shaft 12. A drill bit 15 is fixedly connected to the outer side of the top plate 14. A bottom sleeve 17 is rotatably connected to the bottom of the drill bit 15. The bottom of the bottom sleeve 17 is fixedly connected to the drive motor 11. An anti-clogging device 18 is slidably installed inside the drill bit 15. By starting the drive motor 11, the main shaft 12 connected to it via the coupling will rotate in the forward direction. Therefore, the top plate 14 fixed to the top of the main shaft 12 will rotate, driving the drill bit 15 fixed to its outer side to rotate, thereby achieving the function of rotating and clearing the sludge or debris accumulated inside the pipe.

[0037] The anti-blocking device 18 includes a connecting piece 181, the top of which is fixedly connected to the top plate 14. A hollow plate 182 is fixedly connected to the outer side of the connecting piece 181. A float 183 is slidably installed on the inner side of the hollow plate 182. An extension block 185 is inserted into the outer end of the float 183. Springs 184 are symmetrically arranged on both sides of the float 183. One end of the spring 184 is fixedly connected to the extension block 185. The end of the spring 184 away from the extension block 185 is fixedly connected to the hollow plate 182. A drain strip 186 is fixedly connected to the end of the extension block 185 away from the spring 184. The extension block 185 is slidably installed inside the drill bit 15. Because the bottom of the top plate 14 is fixedly connected to the connecting piece 181, and a hollow plate 182 is fixedly connected to the outer side of the connecting piece 181, and the interior of the hollow plate 182 is slidably connected to the float 183, with one end of the float 183 inserted into the extension block 185, and the extension block 185 is slidably installed inside the drill bit 15, when the drill bit 15 rotates, the extension block 185 will also rotate, and will also drive the float 183 to rotate. During its rotation, it will squeeze the seat block 16. The seat block 16 is mounted on the outside of the spindle 12 via the bearing 13, so the seat block 16 is fixed. At this time, the float block 183 will enter the interior of the extension block 185 in the opposite direction and squeeze it in the opposite direction. Then the extension block 185 will move outward from the interior of the drill bit 15 and drive the unclogging strip 186 fixed at its other end to move outward. At this time, the unclogging strip 186 plays the role of cleaning the silt or debris from the threaded curve hole on the surface of the drill bit 15, preventing the accumulation of silt or debris from affecting the working efficiency of the drill bit 15.

[0038] The spring 184 is always in a taut state, which serves to return and limit the extension block 185. The limiting function is to prevent the extension block 185 from sliding out and falling off from the drill bit 15 during the return process.

[0039] In the second embodiment, as shown in Figures 4-5, the cleaner 2 includes a cleaning plate 29. An external rod 28 is fixedly connected to the bottom of the cleaning plate 29. A deflection rod 27 is fixedly connected to the end of the external rod 28 away from the cleaning plate 29. A fixing seat 25 is provided at the end of the deflection rod 27 away from the external rod 28. Clamping pieces 26 are fixedly connected to both the upper and lower sides of the fixing seat 25. The inner side of the clamping pieces 26 is rotatably connected to the deflection rod 27. A triangular plate 201 is fixedly connected to the bottom of the clamping pieces 26. A slotted shell 21 is slidably installed on the outer side of the triangular plate 201. One end of the slotted shell 21 is fixedly connected to the drive motor 11, and the end of the slotted shell 21 away from the drive motor 11 is sleeved on the inner wall of the outer shell 31. A fixing ring 22 is fixedly connected to the outer side of the slotted shell 21, and a side plate 23 is fixedly connected to the inner side of the fixing ring 22. A threaded rod 24 is threadedly connected to the inside of the side plate 23. A pull rod 20 is fixedly connected to the inner side of the fixing ring 22. The end of the pull rod 20 away from the fixing ring 22 is fixedly connected to an external rod 28. The pull rod 20 and the side plate 23 are fixed to the fixing ring 22 in a circumferentially staggered manner. First, the cleaner 2 is placed inside the pipe, and the cleaning plate 29 is pressed tightly against the inner wall of the pipe. The external rod 28 fixed to the bottom of the cleaning plate 29 has a certain degree of flexibility. Then, the threaded rod 24 is rotated to make it move forward on the side plate 23. Subsequently, the threaded rod 24 will squeeze the fixed seat 25. The upper and lower sides of the fixed seat 25 are fixedly connected with clamping plates 26, and the bottom clamping plate 26 is fixedly connected to the triangular plate 201. Therefore, the triangular plate 201 will slide forward along the outer side of the slotted shell 21. In addition, the inner side of the clamping plate 26 is rotatably connected to the deflection rod 27. The other end of the deflection rod 27 is connected to the external rod 28. Therefore, when the clamping plate 26 moves forward, the deflection rod 27 will rotate clockwise. The reason for the rotation of the deflection rod 27 is that the cleaning plate 29 has been placed inside the pipe and the external rod 28 is bent, so the cleaning plate 29 is squeezed and adapted to the inner wall of the pipe.

[0040] The rotation of the deflection rod 27 increases the bending effect of the outer rod 28 and prevents the cleaning plate 29 from being squeezed against the inner wall of the pipe. Thus, the rotation of the deflection rod 27 is used to achieve the contact relationship between the cleaning plate 29 and the inner wall of the pipe, so as to appropriately adjust the cleaning plate 29 according to the different sizes of pipes and the viscosity of dirt on the inner wall of the pipe.

[0041] In the third embodiment, as shown in Figures 6-8, the mover 3 includes a housing 31. One end of the housing 31 is sleeved with the cleaner 2, and the end of the housing 31 away from the cleaner 2 is fixedly connected to the sprinkler tank 4. A compression sleeve 39 is provided inside the housing 31, and the end face of the compression sleeve 39 is fixedly connected to the cleaner 2. An airbag 30 is provided on the side of the compression sleeve 39 away from the cleaner 2. The airbag 30 is fixedly installed inside the housing 31. A ventilation rod 32 is fixedly connected to the outside of the airbag 30. An external connecting strip 303 is fixedly connected to the end of the ventilation rod 32 away from the airbag 30. A moving block 304 is fixedly connected to the inner end of the external connecting strip 303. A support plate 37 is provided on the side, and a sliding groove 302 is opened on the inner side of the support plate 37. The moving block 304 is slidably installed inside the sliding groove 302. A bent rod 301 is slidably installed on the inner side of the sliding groove 302. The two ends of the bent rod 301 are fixedly connected to the outer shell 31. A connecting ring 33 is fixedly connected to the outer end of the outer connecting strip 303. An anti-fouling block 34 is fixedly connected to the top of the connecting ring 33. A diverter plate 35 is fixedly connected to the top of the anti-fouling block 34. A protective wheel 36 is provided on the outer side of the diverter plate 35. The protective wheel 36 is rotatably installed on the inner side of the support plate 37. A limit plate 38 is slidably installed on the outer side of the support plate 37. The end face of the limit plate 38 is fixedly connected to the anti-fouling block 34. Because the slotted shell 21 is fitted onto the inner wall of the outer shell 31, pushing the outer shell 31 towards the slotted shell 21 will cause the compression sleeve 39 connected to the inner wall of the slotted shell 21 to compress the airbag 30. At this time, the airbag 30 will be compressed and bulge outwards. Therefore, the airbag 30 will first compress the venting rod 32. The other end of the venting rod 32 is connected to the outer connecting strip 303, and the outer connecting strip 303 is slidably connected to the sliding groove 302 via the moving block 304. Therefore, the outer connecting strip 303 will... The outer strip 303 moves upward, and the other end of the outer strip 303 is connected to the connecting ring 33. The top of the connecting ring 33 is fixedly connected to the anti-fouling block 34. The anti-fouling block 34, which moves upward, protects and prevents the protective wheel 36 from being contaminated. In addition, the diverter plate 35, which is fixedly connected to the top of the anti-fouling block 34, diverts the dirt or debris removed by the cleaner 2 to the left and right, and prevents dirt from flowing into the interior of the protective wheel 36 or the junction, causing the protective wheel 36 to jam or other problems.

[0042] Continue squeezing the airbag 30 until it finally compresses the support plate 37. At this point, the support plate 37 will move upward along the bent rod 301. Consequently, the protective wheel 36, which is rotated and installed on the inner side of the support plate 37, will also move upward, thus enabling the movement of pipes of different sizes.

[0043] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
