Description
Technical Field
[0001] This utility model belongs to the field of pipeline dredging technology, specifically a high-efficiency dredging robot for municipal drainage systems. Background Technology
[0002] As people's living standards continue to improve, urban construction is becoming increasingly large-scale. Pipeline construction is a major part of municipal work. The amount of pipelines laid in a city is no less than the amount of construction work. However, with the increase in the number of pipelines laid, many problems have also been exposed. For example, many pipelines are prone to blockage due to the presence of dirt inside. Therefore, pipeline dredging work consumes a lot of manpower and resources and has very low efficiency.
[0003] To address the problems of high workload and low efficiency in traditional manual dredging, pipeline dredging robots have emerged. However, existing municipal pipeline dredging robots have relatively limited functions, mostly focusing solely on dredging and unblocking. The negative effects generated during the dredging process are often overlooked, such as: 1. The drill bits and other cleaning components rigidly connected to the robot body operate at high speeds during unblocking. The high-frequency vibrations generated when they come into contact with sludge indirectly affect the robot body, causing irreversible damage to many internal components. This reduces the robot's lifespan, increases pipeline dredging costs, and reduces dredging efficiency; 2. Some high-pressure flushing dredging robots with drill bits use high pressure to drive the drill bit forward, while simultaneously flushing away blockages with high-pressure water jets. They are simple to operate and easy to transport. However, they cannot guarantee that the drill bit is centered in the pipe, causing it to sway arbitrarily and damage the pipe wall. Furthermore, the radially sprayed high-pressure water creates varying pressures on the pipe walls, further increasing damage. Additionally, some robots have limited applicability and are inconvenient to store and carry. Therefore, there is a need to develop a new, high-efficiency dredging robot for municipal drainage systems to address the shortcomings of existing technologies. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 5 As shown, this utility model provides a high-efficiency dredging robot for municipal drainage systems, including a robot body 1. A support mechanism is provided on the outer surface of the robot body 1. A connecting component 10 is connected to one end of the robot body 1. A drill bit component 2 is provided at the other end of the robot body 1. A buffer component 3 is provided between the robot body 1 and the drill bit component 2. The buffer component 3 is fixedly connected to the robot body 1. A dredging component 4 is provided inside the robot body 1 and the buffer component 3. One end of the dredging component 4 is rotatably connected to the inner wall of the robot body 1 through a connecting frame. The other end of the dredging component 4 passes through the robot body 1 and the buffer component 3 and is connected to the drill bit component 2.
[0028] The buffer assembly 3 includes a buffer sleeve 31 fixedly connected to the robot body 1. A first compression ring 32 is movably installed inside the buffer sleeve 31. A buffer spring 35 is connected to one end of the first compression ring 32, and a drag-reducing ring 33 is movably connected to the other end of the first compression ring 32. The other end of the drag-reducing ring 33 passes through the buffer sleeve 31 and is fixedly connected to the drill bit component 2 through the separation assembly 4. A plurality of uniformly distributed drag-reducing balls 34 are movably embedded on both sides and the outer surface of the drag-reducing ring 33, which is sleeved inside the buffer sleeve 31. The drag-reducing balls 34 roll in contact with the inner wall of the buffer sleeve 31 and the outer surface of the first compression ring 32. Due to the setting of the buffer assembly 3, with the cooperation of the first compression ring 32 and the drag-reducing ring 33, the drill bit component 2 can compress the buffer spring 35 with the cooperation of the separation assembly 4. In this way, the elastic effect of the buffer spring 35 can eliminate the impact of the high-frequency vibration of the drill bit component 2 during drilling on the robot body 1 and other components, effectively reducing the damage caused by vibration to the components and extending the service life of the equipment.
[0029] The buffer sleeve 31 is internally equipped with a second compression ring 36 that abuts against the other end of the buffer spring 35. A pressure sensor 37 is connected between the other side of the second compression ring 36 and the inside of the buffer sleeve 31. A plurality of evenly distributed spray assemblies 9 are connected to the side of the buffer sleeve 31 near the support mechanism. Each spray assembly 9 consists of interconnected nozzles 91 and connecting pipes 92. The other end of the nozzles 91 is connected to the side of the buffer sleeve 31. The connecting pipe 92 is fixedly connected to the support mechanism and is inclined towards the end of the support mechanism away from the buffer assembly 3. Due to the second compression ring 36, the buffer spring 35 can withstand pressure... The pressure is applied to the pressure sensor 37 through the second compression ring 36. Due to the movable connection of the drill bit component 2, the force around it is uneven. It can indirectly act on several pressure sensors 37 through the linkage ring 41, the resistance reducing ring 33, the first compression ring 32, the buffer spring 35, and the second compression ring 36. It is not possible for the four pressure sensors 37 to transmit pressure values of corresponding intensity to the outside, so that the operator can remotely control the drilling intensity and progress. Due to the setting of the connecting pipe 92, with the cooperation of the nozzle 91, it can not only flush the foreign objects on the pipe wall, but also provide the forward propulsion force for the equipment under the reaction force, thereby achieving the effect of continuous drilling and unblocking.
[0030] The evacuation component 4 includes a linkage ring 41 fixedly connected between the drag-reducing ring 33 and the drill bit component 2. A number of uniformly distributed blades 42 are fixedly connected to the outer surface of the linkage ring 41. The distance between the outer surface of the blades 42 and the centerline of the linkage ring 41 is less than the inner diameter of the buffer sleeve 31. A number of uniformly distributed injection holes 11 are opened on the outer surface of the buffer sleeve 31. Due to the setting of the linkage ring 41, the drill bit component 2 can obtain a buffering effect with the elastic action of the buffer spring 35 in cooperation with the drag-reducing ring 33. At the same time, the drill bit component 2 can continuously drill with the cooperation of the buffer component 3, the evacuation component 4 and the injection component 9. Moreover, the rapidly rotating drill bit body 21 can drive the blades 42 on its outer surface to rotate rapidly through the linkage ring 41, so that the sewage and debris on the outside of the blades 42 can obtain centrifugal force, thus preventing them from approaching or even entering the interior of the buffer sleeve 31. This avoids the sewage from entering and increasing the frictional resistance of the drag-reducing ball 34, and at the same time avoids excessive corrosion of the buffer spring 35 and other components.
[0031] The drill bit component 2 includes a drill bit body 21 located at the front end of the robot body 1 and fixedly connected to the end of the linkage ring 41. The outer surface of the drill bit body 21 is provided with drill teeth 22. The drill bit body 21 is a hollow structure, and an impact hole 23 is provided at the other end of the drill bit body 21.
[0032] The linkage ring 41 is fitted with a linkage guide cone 44 inside. The linkage guide cone 44 and the drill body 21 are cone-shaped structures that are opposite to each other. The other end of the linkage guide cone 44 is rotatably connected to the inner wall of the robot body 1 through a connecting frame. The outer surface of the linkage guide cone 44 is provided with a drive turbine blade 45. A gap is left between the outer surface of the drive turbine blade 45 and the inner wall of the robot body 1.
[0033] A plurality of evenly distributed linkage blocks 46 are provided between the outer surface of the linkage guide cone 44 and the linkage ring 41. One end of the linkage block 46 is fixedly connected to the linkage guide cone 44, and the other end of the linkage block 46 is movably embedded with a linkage ball 47. A plurality of evenly distributed linkage grooves 43 are provided on the inner wall of the linkage ring 41. The linkage grooves 43 correspond one-to-one with the linkage blocks 46. The outer surface of the linkage ball 47 is rolledly connected to the inside of the linkage groove 43. Due to the setting of the linkage grooves 43, with the cooperation of the linkage blocks 46 and the linkage ball 47, it is ensured that the linkage guide cone 44 can drive the drill body 21 to rotate when it rotates. At the same time, when the drill part 2 moves axially relative to the robot body 1 at the moment of impact, it can avoid being affected by the linkage guide cone 44 with the cooperation of the linkage grooves 43 and the linkage ball 47, and avoid vibration damage to the linkage guide cone 44.
[0034] The support mechanism consists of several evenly distributed support rods 5, a walking component 6, an adapter groove 7, and a holding component 8. One end of the support rod 5 is movably hinged to the side of the buffer sleeve 31, the walking component 6 is rotatably connected to the other end of the support rod 5, the adapter groove 7 is opened on the outer surface of the robot body 1 and below the support rod 5, and the holding component 8 is set inside the robot body 1. One end of the holding component 8 is connected to the connecting component 10 through the robot body 1, and the other end of the holding component 8 is connected to the support rod 5.
[0035] The walking component 6 includes a walking support frame 61 rotatably connected to the end of the support rod 5. The walking support frame 61 has several evenly distributed walking wheels 62 movably connected inside, and the walking wheels 62 are rolled on the pipe wall. Due to the setting of the adapter groove 7, with the cooperation of the abutment component 8, it is easy to store the walking component 6 on the surface of the robot body 1 through the support rod 5, so that the overall storage effect of the equipment is better, and it will not affect the length requirement of the walking component 6. In addition, by lengthening the walking component 6, the axial stability after fitting against the pipe wall is better, and the drilling stability of the equipment is improved.
[0036] The supporting component 8 includes a sealing cavity 81 located inside the robot body 1 and connected to the adapter groove 7 near one end of the connecting component 10. A piston rod 82 is sealed inside the sealing cavity 81. The other end of the piston rod 82 passes through the sealing cavity 81 and extends into the adapter groove 7, where it is hinged to a supporting rod 83. The other end of the supporting rod 83 is hinged to the middle of the support rod 5 away from the walking component 6. Because it is evenly distributed in the support mechanism, it can stably support the equipment in the middle of the pipe with the cooperation of the robot body 1 and the connecting component 10, thereby ensuring that the impact intensity of the high-pressure water sprayed in all directions on the pipe wall is the same. This facilitates the flushing of foreign objects and makes it easy to control the intensity of the high-pressure water, avoiding uneven impact on the pipe wall and damage to the pipe.
[0037] The connecting component 10 includes a connecting post 101 fixedly sleeved inside the robot body 1 at one end away from the drill bit component 2. One end of the connecting post 101 is connected to the area between the robot body 1 and the linkage guide cone 44. The other end of the connecting post 101 extends to the outside of the robot body 1 and is fixedly connected to a shaft sealing ring 106. The other end of the shaft sealing ring 106 is sealed and sleeved with a connecting pipe 102. The other end of the connecting pipe 102 is connected to a pump.
[0038] A second solenoid valve 105 is provided at one end of the connecting column 101 that is connected to the inside of the robot body 1. A connecting cavity 103 is opened inside the connecting column 101. A first solenoid valve 104 is connected between the middle part of the connecting column 101 and the connecting cavity 103. A number of evenly distributed through holes are opened inside the robot body 1. The first solenoid valve 104 is connected to the corresponding sealing cavity 81 through the number of through holes. Due to the setting of the first solenoid valve 104 and the second solenoid valve 105, it is convenient for the staff to control the flow direction of high pressure or low pressure water, so as to adjust the opening degree of the support mechanism, as well as the drilling efficiency and impact strength.
[0039] Working principle and usage process of this utility model:
[0040] Connect the other end of the connecting pipe 102 to the pump, place the equipment in the pipe to be unclogged, open the first solenoid valve 104 and keep the second solenoid valve 105 closed, then start the pump to allow low-pressure water to enter several sealed cavities 81 through the connecting pipe 102, connecting column 101 and connecting cavity 103 via the through hole in the robot body 1. Then, under the restriction of the sealed cavity 81, the piston rod 82 is pushed, and the other end of the piston rod 82 pushes the support rod 5 with the cooperation of the adapter groove 7. One end of the support rod 5 drives the walking component 6 to swing, and the walking component 6 gradually moves away from the robot body 1 until several walking components 6 simultaneously adhere to the inner wall of the pipe.
[0041] After closing the first solenoid valve 104 and opening the second solenoid valve 105, the high-pressure water flows through the connecting pipe 102, connecting column 101 and the second solenoid valve 105 and impacts the drive turbine blades 45 on the surface of the linkage guide cone 44 through the robot body 1, causing the linkage guide cone 44 to rotate. When the linkage guide cone 44 rotates, the linkage ring 41 rotates through the linkage block 46 under the cooperation of the linkage ball 47 and the linkage slide 43. The rotation of the linkage ring 41 drives the drill body 21 to rotate, and at the same time, the drill teeth 22 on the surface of the drill body 21 rotate.
[0042] The first part of the high-pressure water enters the drill bit body 21 after passing through the buffer sleeve 31 and is sprayed forward through the impact hole 23 to open the blockage in front, so that the front end of the drill bit body 21 can be inserted into the blockage, and the drill teeth 22 that follow the rotation of the drill bit body 21 can further drill open the blockage.
[0043] After the second part of the high-pressure water enters the buffer sleeve 31, it is sprayed radially out through the spray holes 11 on the outer surface, thereby impacting the blockage around the drill bit body 21 after drilling, so as to ensure the continuous advancement of the equipment.
[0044] The third part of the high-pressure water enters the connecting pipe 92 after passing through the buffer sleeve 31 and is sprayed by the nozzle 91 onto the pipe wall and surrounding blockages, further flushing the blockages and cleaning and closing the pipe.
[0045] Meanwhile, because the connecting pipe 92 is tilted, when it is sprayed out, it acts on the blockage on the pipe wall. Due to the reaction force, the robot body 1 moves forward as a whole, which in turn causes the drill teeth 22, which follow the drill body 21 to rotate rapidly, to break through the blockage.
[0046] When continuously drilling into the blockage fault, the reaction force of the high-pressure water causes the robot body 1 and the drill bit component 2 at its front end to move rapidly. This may cause the front end of the drill bit body 21 to collide with a new blockage. At this time, the elastic action of the buffer spring 35 prevents the instantaneous impact between the drill bit body 21 and the blockage from directly affecting the robot body 1, greatly reducing the impact of vibration on components other than the drill bit component 2 and avoiding the loosening of other component connections.
