Description

Technical Field

[0001] This invention belongs to the field of pipeline cleaning technology, specifically referring to an automatic cleaning device for the inner wall of a large drainage pipeline. Background Technology

[0002] Over time, drainage pipes accumulate a large amount of sludge, moss, and other debris on their inner walls. These debris need to be cleaned regularly; otherwise, it will not only affect the effective diameter of the drainage pipe but also cause more and more impurities to adhere to the inner wall of the pipe. Furthermore, the deposits that are not cleaned for a long time will become increasingly difficult to remove.

[0003] The "large" drainage pipes mentioned in this invention refer to pipes with an inner diameter of more than 500 mm. These pipes have a relatively large inner diameter and are generally not easy to be blocked as a whole. Instead, they are prone to accumulating mud and dirt on the inner wall. Furthermore, due to the large inner diameter, the diameter-to-thickness ratio (the ratio of diameter to wall thickness) is also large, making it difficult to implement the general cleaning method that uses a traction head to clear the blockage.

[0004] For many drainage pipes, manual drilling is required to clean them. However, this not only results in poor sanitation conditions and high labor intensity, but also makes it difficult for manual drilling into some drainage pipes.

[0005] Based on the above requirements, the present invention aims to provide a cleaning device capable of automatically cleaning the inner wall of a pipe. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a technique for cleaning the interior of pipes using high-pressure water jets. The recoil force of the high-pressure water jets causes the equipment to move within the pipe, achieving automated operation. This technique can replace manual cleaning of the pipe's inner wall. The equipment can be used with various pipe types. While flushing and removing contaminants from the pipe's inner wall with high-pressure water, the reaction force of the high-pressure water jets also drives the nozzle to rotate. Furthermore, due to the angle between the nozzle and the rotating plane, the spray mechanism slowly moves along the pipe's axial direction while rotating, thus automatically cleaning the entire inner wall of the pipe.

[0007] An automatic cleaning device for the inner wall of a large drainage pipe, comprising:

[0008] The water pump is connected to an external water source.

[0009] A water-passing mechanism is connected to the water pump, and a water-passing channel is formed within the water-passing mechanism;

[0010] A support mechanism is spaced apart and connected to the water-passing mechanism. The support mechanism includes a support component and a first roller. One end of the support component is connected to the water-passing mechanism, and the other end is connected to the first roller.

[0011] At least two water spraying mechanisms are provided, all of which are spaced apart around the periphery of the water-passing mechanism. Each water spraying mechanism includes a water spraying component and a second roller. The water spraying component includes a water spraying channel and an inlet and a spray nozzle communicating with the water spraying channel. One end of the water spraying component with the inlet is connected to the water-passing mechanism, and the inlet is connected to the water-passing channel. The second roller is connected to one end of the water spraying component with the spray nozzle.

[0012] In this configuration, all the spray nozzles of the spray mechanism are opened on the same side of the periphery of the water passage mechanism. When all the spray nozzles spray water, the end of the spray assembly with the spray nozzle can be controlled to rotate circumferentially along the water passage mechanism, and drive the second roller to move synchronously. All the spray nozzles of the spray mechanism are opened on the same side of the axial direction of the water passage mechanism. When all the spray nozzles spray water, the spray assembly will be subjected to a thrust that moves along the axial direction of the water passage mechanism, and drive the entire inner wall automatic cleaning device to move along the axial direction of the water passage mechanism.

[0013] In one embodiment, the water spray assembly includes a water spray element, a first telescopic rod, and a second telescopic rod. The first telescopic rod and the second telescopic rod respectively form a through first water spray chamber and a second water spray chamber. The first telescopic rod is telescopically sleeved on the outside of one end of the second telescopic rod, so that the first water spray chamber and the second water spray chamber are connected to form the water spray channel. The end of the second telescopic rod opposite to the first telescopic rod forms the water inlet and is movably connected to the water passage mechanism.

[0014] One end of the water spray component is movably connected to the end of the first telescopic rod opposite to the second telescopic rod, and the other end is connected to the second roller and is provided with the water spray nozzle.

[0016] The second limiting member is engaged with the locking member, and both are arranged around the periphery of the second telescopic rod near the end of the first telescopic rod. The spring is deformably engaged between the second limiting member and the first limiting member.

[0017] When the locking member is locked, both the second limiting member and the locking member are fixedly connected to the first telescopic member.

[0018] In one embodiment, the water spray component includes a water spray section and an installation section connected to each other. The installation section extends in a straight line and is used to insert into the first water spray chamber of the first telescopic rod and is controllably movable relative to the first telescopic rod in a circumferential direction.

[0019] In one embodiment, the water-passing mechanism includes a water-passing assembly, which includes a first water-passing component, a second water-passing component, and a first connecting component. The first water-passing component, the first connecting component, and the second water-passing component are sequentially connected to form the water-passing channel. The end of the first water-passing component facing away from the second water-passing component is connected to the water pump.

[0020] One end of the second water-passing component is movably connected to the first water-passing component, and the other end is fixedly connected to the water spray assembly. The second water-passing component can be controlled to rotate relative to the first connecting component along its own axis.

[0021] In one embodiment, the water-passing mechanism includes a housing and a second connecting member. The housing has an annular opening that communicates with the mounting cavity. The water-passing component is fitted into the mounting cavity. The first water-passing member extends out through one end opening of the mounting cavity and communicates with the water pump. The second water-passing member is rotatably fitted into the mounting cavity.

[0022] The annular opening extends and closes around the periphery of the housing, and the second connector is movably fitted onto the housing and seals the annular opening;

[0023] The second connector has multiple clearance openings, each of which corresponds to a water spraying mechanism. The end of the water spraying assembly with a roller passes through the mounting cavity, the annular opening, and the clearance opening in sequence to extend to the outside of the housing.

[0024] In one embodiment, the support mechanism includes two support components arranged at an included angle;

[0025] Both of the support components include a first support rod and a second support rod. One end of the first support rod of each of the two support components is connected to the water-passing mechanism and intersecting with it. The other end of the first support rod of each of the two support components can be telescopically inserted into one end of the corresponding second support rod. The end of the second support rod of each of the two support components opposite to the first support rod is connected to the first roller.

[0026] In one embodiment, the support mechanism further includes an adjusting rod, a first stabilizing rod, and a second stabilizing rod. The adjusting rod is arranged along the angle bisector of the angle formed by the two support components, and one end of the adjusting rod is connected to the intersection of the two support components.

[0027] One end of the first stabilizer and one end of the second stabilizer are respectively connected to the two ends of the second support rods near the first support rod. The other ends of the first stabilizer and the second stabilizer are movably connected to the adjusting rod and intersect to form an intersection point. The intersecting ends of the first stabilizer and the second stabilizer can be controlled to extend and retract to move the position of the intersection point on the adjusting rod.

[0028] In one embodiment, the support mechanism further includes an adjusting member, which includes a first sleeve, a second sleeve, and a third sleeve. The first sleeve and the second sleeve are intersecting, and the third sleeve is fixed to the intersection of the first sleeve and the second sleeve. The first sleeve and the second sleeve are movably sleeved on the first stabilizing rod and the second stabilizing rod, respectively, and the third sleeve is movably sleeved on the adjusting rod.

[0029] In one embodiment, the support mechanism further includes a fixing pin, the adjusting rod is provided with a plurality of pin holes at intervals, the third sleeve is provided with a mating hole, the third sleeve can be controlled to move relative to the adjusting rod to a position where the mating hole is aligned with any of the pin holes, and the fixing pin passes through the mating hole and the aligned pin hole.

[0030] The aforementioned large drainage pipe's internal wall automatic cleaning device includes a water pump, a water-passing mechanism, a support mechanism, and at least two spray mechanisms. The water pump is connected to an external water source. The water-passing mechanism is connected to the water pump, and a water-passing channel is formed within the water-passing mechanism. The support mechanism is spaced apart and connected to the water-passing mechanism. The support mechanism includes a support component and a first roller, with one end of the support component connected to the water-passing mechanism and the other end connected to the first roller. All water spraying mechanisms are spaced around the periphery of the water system. Each water spraying mechanism includes a water spraying component and a second roller. The water spraying component includes a water spraying channel and an inlet and a nozzle connected to the water spraying channel. One end of the water spraying component with the inlet is connected to the water system, and the inlet is connected to the water channel. The other end of the water spraying component with the nozzle is connected to the second roller. All the nozzles of the water spraying mechanism are opened on the same side along the periphery of the water system. When all the nozzles spray water, the end of the water spraying component with the nozzle can be controlled to rotate circumferentially along the water system, and drive the second roller to move synchronously. The automatic inner wall cleaning device provided in this application embodiment pumps water from an external water source into a water-passing mechanism, which then transports the water flow to a spraying mechanism for spraying. Furthermore, during the spraying process, the spraying generates a force opposite to the spraying direction on the spraying components, which can drive the automatic inner wall cleaning device to move axially along the pipe and drive all spraying components to rotate circumferentially along the water-passing mechanism to spray water, thereby achieving comprehensive cleaning of the inner wall of the pipe. At the same time, it can realize the automatic displacement of the automatic inner wall cleaning device for large drainage pipes, which can save labor costs, is simple to operate, and is conducive to improving cleaning efficiency and user experience.

[0050] Please see Figure 1 , Figure 2 and Figure 3 This application provides an automatic cleaning device for the inner wall of a large drainage pipe. The automatic cleaning device includes a water pump 5, a water passage mechanism 1, a support mechanism 2, and at least two water spraying mechanisms 3.

[0051] It should be noted that the automatic inner wall cleaning device provided in this application embodiment is used in the technical field of pipeline cleaning. The automatic inner wall cleaning device can enter the interior of a pipeline and clean its inner wall. It should also be noted that the automatic inner wall cleaning device provided in this application embodiment can be applied to other fields.

[0052] The water pump 5 is connected to an external water source. The water-passing mechanism 1 is connected to the water pump 5, and a water-passing channel 2 is formed inside the water-passing mechanism 1. The support mechanism 2 is spaced apart and connected to the water-passing mechanism 1. The support mechanism 2 includes a support component 22 and a first roller 21. One end of the support component 22 is connected to the water-passing mechanism 1, and the other end is connected to the first roller 21.

[0053] All water spraying mechanisms 3 are arranged at intervals around the periphery of water mechanism 1. Water spraying mechanism 3 includes water spraying component 33 and second roller 31. Water spraying component 33 includes water spraying channel 32 and water inlet 322 and water nozzle 321 connected to water spraying channel 32. One end of water spraying component 33 with water inlet 322 is connected to water mechanism 1 and water inlet 322 is connected to water channel 2. The second roller 31 is connected to one end of water spraying component 33 with water nozzle 321.

[0054] Understandably, during the actual operation of the automatic inner wall cleaning device, it needs to be placed inside the pipe. The support mechanism 2 is supported between the water-passing mechanism 1 and the inner wall of the pipe, and the first roller 21 can be controlled to move axially along the inner wall of the pipe, thus driving the entire automatic inner wall cleaning device to move axially along the inner wall of the pipe. All water spraying mechanisms 3 are supported between the water-passing mechanism 1 and the inner wall of the pipe, and the second roller 31 can be controlled to move circumferentially along the inner wall of the pipe, thus driving the entire automatic inner wall cleaning device to move circumferentially along the inner wall of the pipe. Therefore, when the automatic inner wall cleaning device is placed inside the pipe, the axial direction of the water-passing mechanism 1 is consistent with the axial direction of the pipe, and the circumferential direction of the water-passing mechanism 1 is consistent with the circumferential direction of the pipe.

[0055] All water spray nozzles 321 of the water spraying mechanism 3 are opened on the same side along the periphery of the water conveying mechanism 1. When all water spray nozzles 321 spray water, the end of the water spraying assembly 33 with the water spray nozzles 321 can be controlled to rotate circumferentially along the water conveying mechanism 1, and drive the second roller 31 to move synchronously. All water spray nozzles 321 of the water spraying mechanism 3 are opened on the same side along the axial direction of the water conveying mechanism 1. When all water spray nozzles 321 spray water, the water spraying assembly 33 will be subjected to a thrust that moves along the axial direction of the water conveying mechanism 1, and drive the entire inner wall automatic cleaning device to move along the axial direction of the water conveying mechanism 1.

[0056] Understandably, during the actual operation of the automatic inner wall cleaning device, the water pump 5 is controlled to send water from the external water source to the water passage 2 of the water passage mechanism 1. The water flowing into the water passage 2 will flow through the inlet 322 and the spray channel 32 in sequence until it is sprayed out from the spray nozzle 321 of the spray channel 32 and acts on the inner wall of the pipe, thereby achieving the effect of cleaning the inner wall of the pipe. Since all the water spraying mechanisms 3 are spaced around the periphery of the water mechanism 1, all the spray nozzles 321 of all the water spraying mechanisms 3 are opened on the same side of the periphery of the water-passing mechanism 1, and all the spray nozzles 321 of all the water spraying mechanisms 3 are opened on the same side of the axis of the water-passing mechanism 1, when all the spray nozzles 321 spray water, they will generate a force on the water spraying assembly 33 opposite to the direction of water spraying. This force will drive the end of the water spraying assembly 33 with the spray nozzles 321 to rotate around the periphery of the water-passing mechanism 1 to thoroughly clean the inner wall of the pipe. The second roller 31 will also roll on the inner wall of the pipe around the periphery of the water-passing mechanism 1 under the drive of the water spraying assembly 33. At the same time, this force will also push the entire automatic inner wall cleaning device to move along the axis of the water-passing mechanism 1, and the second roller 31 will roll on the inner wall of the pipe along the axis of the water-passing mechanism 1 under the drive of the water spraying assembly 33.

[0057] It is understandable that when all the spray nozzles 321 are spraying water, the automatic cleaning device for the inner wall will move along the axial direction of the pipe. At the same time, the spray assembly 33 can rotate around the water passage mechanism 1 to spray water, so as to clean the inner wall of the pipe along the circumference of the pipe. Thus, the path of the automatic cleaning device for the inner wall spraying water is spiral.

[0058] The automatic inner wall cleaning device provided in this application embodiment delivers water from an external water source to the water-passing mechanism 1 via a water pump 5. The water-passing mechanism 1 then transports the water flow to the spraying mechanism 3 to achieve water spraying. Furthermore, during the water spraying process, the spraying force generated on the spraying components 33 in the opposite direction to the spraying direction can be used to push the automatic inner wall cleaning device to move along the axial direction of the pipe and push all the spraying components 33 to rotate circumferentially along the water-passing mechanism 1 to spray water, thereby achieving comprehensive cleaning of the inner wall of the pipe. At the same time, it can realize the automatic displacement of the automatic inner wall cleaning device, which can save labor costs and is simple to operate, thus improving cleaning efficiency and user experience.

[0059] The specific style of the water spray assembly is not limited. For some embodiments, please refer to [link / reference]. Figure 3 and Figure 4The water spray assembly 33 includes a water spray element 331, a first telescopic rod 334 and a second telescopic rod 336. The first telescopic rod 334 and the second telescopic rod 336 respectively form a through first water spray cavity 335 and a second water spray cavity 337. The first telescopic rod 334 is telescopically sleeved on the outside of one end of the second telescopic rod 336, so that the first water spray cavity 335 and the second water spray cavity 337 are connected to form a water spray channel 32. The end of the second telescopic rod 336 opposite to the first telescopic rod 334 forms a water inlet 322 and is movably connected to the water passage mechanism 1.

[0060] One end of the water spray component 331 is movably connected to one end of the first telescopic rod that is away from the second telescopic rod 336, and the other end is connected to the second roller 31 and is provided with a water spray nozzle 321.

[0061] Understandably, the user can control the movement of the first telescopic rod 334 relative to the second telescopic rod 336 according to the actual size of the pipe's inner diameter, so as to adjust the overall length of the water spray assembly 33 until the second roller 31 is in contact with the inner wall of the pipe. In this way, the water spray assembly 33 can be supported between the water passage mechanism 1 and the inner wall of the pipe, and the second roller 31 can be controlled to roll along the circumference of the pipe on the inner wall of the pipe when water is sprayed from the water nozzle 321, so as to ensure the stability of the automatic cleaning device assembly.

[0062] In some embodiments, see Figure 2 and Figure 7 The water spraying mechanism 3 also includes a locking assembly 34, which includes a locking member 341, a spring 342, a first limiting member 343 and a second limiting member 344. The first limiting member 343 is arranged around the periphery of the second telescopic rod 336 near the end of the first telescopic rod 334.

[0063] The second limiting member 344 is engaged with the locking member 341, and both are arranged around the periphery of the second telescopic rod 336 near the end of the first telescopic rod 334. The spring 342 is deformably engaged between the second limiting member 344 and the first limiting member 343.

[0064] When the locking member 341 is locked, both the second limiting member 344 and the locking member 341 are fixedly connected to the first telescopic member.

[0065] Understandably, when the locking member 341 is unlocked, the second telescopic rod 336 can move relative to the second limiting member 344 and the locking member 341. The second limiting member 344 and the locking member 341 are connected to the first limiting member 343 through the spring 342. Therefore, when the second telescopic rod 336 moves, the relative positional relationship between the first limiting member 343, the second limiting member 344 and the locking member 341 remains unchanged. In this way, the user can control the movement of the first telescopic rod 334 relative to the second telescopic rod 336 according to the actual inner diameter of the pipe to adjust the overall length of the water spray assembly 33 until the second roller 31 is in contact with the inner wall of the pipe.

[0066] After adjusting the overall length of the water spray assembly 33, the locking member 341 needs to be locked so that both the second limiting member 344 and the locking member 341 are fixedly connected to the first telescopic member. Thus, during the actual operation of the automatic inner wall cleaning device, when there are irregular protrusions inside the pipe and the second roller 31 rolls on them, the second roller 31 will push the first telescopic rod 334 to move towards the first telescopic rod 334 to shorten the overall length of the water spray assembly 33. At this time, the first limiting member 343 will move towards the second limiting member 344 and compress the spring 342. The spring 342 will deform and store elastic potential energy. This elastic potential energy can be converted into elastic force after the second roller 31 passes the irregular protrusion to push the first telescopic rod 334 in the direction away from the first telescopic rod 334, so that the second roller 31 can fit against the normal inner wall of the pipe in time. Thus, by setting the locking component 34, this application can achieve a small range of adjustment of the overall length of the water spray component 33, so as to ensure that the second roller 31 can always be in contact with the inner wall of the pipe, and also to prevent the locking component 34 from getting stuck with the inner wall of the pipe. While ensuring the stability of the assembly of the automatic inner wall cleaning device, it can also ensure the normal operation of the automatic inner wall cleaning device.

[0067] The specific design of the water spray component 331 is not limited. For some embodiments, please refer to... Figure 4 The water spray component 331 includes a water spray section 332 and an installation section 333 connected to each other. The installation section 333 extends in a straight line and is used to insert into the first water spray chamber 335 of the first telescopic rod 334. It can be controlled to move relative to the first telescopic rod 334 in a circumferential direction. The water spray section 332 extends in a curved line and a water spray nozzle 321 is provided at the end of the water spray section 332 away from the installation section 333.

[0068] It is understandable that by setting the water spray section 332 as a curved extension, the water spray nozzle 321 of the water spray section 332 can generate a force opposite to the direction of water spray when spraying water, thereby pushing the automatic inner wall cleaning device to move along the axial direction of the pipe and pushing all the water spray components 33 to rotate and spray water along the circumference of the water flow mechanism 1, so as to achieve comprehensive cleaning of the inner wall of the pipe. At the same time, it can realize the automatic displacement of the automatic inner wall cleaning device, which can save labor costs, and is simple to operate, which is conducive to improving cleaning efficiency and user experience.

[0069] During the actual operation of the automatic cleaning device for the inner wall, the user needs to control the installation section 333 of the water spray component 331 to move relative to the first telescopic rod 334 in the circumferential direction around the first telescopic rod 334 according to actual needs, so that all water spray nozzles 321 are opened on the same side along the circumference of the water passage mechanism 1 and all water spray nozzles 321 are opened on the same side along the axial direction of the water passage mechanism 1.

[0070] The specific mating position of the second roller 31 is not limited. In some embodiments, please refer to... Figure 3 and Figure 4 The second roller 31 is connected to the water spray section 332. It can be understood that when the water spray is controlled to move relative to the first telescopic rod 334 in the circumferential direction, the second roller 31 will move synchronously under the drive of the water spray section 332. In this way, the second roller 31 is inclined relative to the inner wall of the pipe, and the direction of the inclination is consistent with the direction of the thrust generated when the water is sprayed from the nozzle 321. Thus, when the water is sprayed from the nozzle 321, the second roller 31 can roll smoothly on the inner wall of the pipe to improve cleaning efficiency.

[0071] The specific design of the water-passing mechanism 1 is not limited. For some embodiments, please refer to... Figure 5 and Figure 6 The water-passing mechanism 1 includes a water-passing component 14, which includes a first water-passing element 141, a second water-passing element 142, and a first connecting element 143. The first water-passing element 141, the first connecting element 143, and the second water-passing element 142 are connected in sequence to form a water-passing channel 2. The end of the first water-passing element 141 that is away from the second water-passing element 142 is connected to the water pump 5.

[0072] One end of the second water-passing component 142 is movably connected to the first water-passing component 141, and the other end is fixedly connected to the water spray assembly 33. The second water-passing component 142 can be controlled to rotate relative to the first connecting component 143 along its own axis.

[0073] Understandably, during the actual operation of the automatic inner wall cleaning device, water from an external water source is pumped through the second water-passing component 142 to the water-passing channel 2 of the water-passing mechanism 1 by controlling the water pump 5. The water flowing into the water-passing channel 2 will flow sequentially through the first connecting component 143, the second water-passing component 142, the inlet 322 of the spray channel 32, and the spray channel 32 until it is sprayed out from the spray nozzle 321 of the spray channel 32. When all the spray nozzles 321 spray water, they will generate a force opposite to the spray direction on the spray assembly 33. This force will drive the spray assembly 33 to rotate circumferentially along the water-passing mechanism 1, and the second water-passing component 142 will rotate synchronously with respect to the first connecting component 143 under the drive of the spray assembly 33. In this way, the comprehensive cleaning of the inner wall of the pipe can be effectively achieved.

[0074] In some embodiments, see Figure 5 and Figure 6 The water-passing mechanism 1 includes a housing 12 and a second connecting member 13. The housing 12 has an annular opening 122 that is connected to the mounting cavity 121. The water-passing component 14 is fitted into the mounting cavity 121. The first water-passing component 141 extends out through one end opening of the mounting cavity 121 and is connected to the water pump 5. The second water-passing component 142 is rotatably fitted into the mounting cavity 121.

[0075] Understandably, the outer casing 12 can protect the first water-passing component 141, the first connecting component 143 and the second water-passing component 142, so as to avoid the probability of damage caused by contact or collision with foreign objects when the automatic inner wall cleaning device is working in the pipeline, which is conducive to improving the service life of the automatic inner wall cleaning device.

[0076] The annular opening 122 extends and closes around the periphery of the outer casing 12, and the second connector 13 is movably fitted onto the outer casing 12 and seals the annular opening 122. The second connector 13 has multiple clearance openings, each of which corresponds to a water spraying mechanism 3. The end of the water spraying assembly 33 with a roller passes through the mounting cavity 121, the annular opening 122 and the clearance opening in sequence and extends to the outside of the outer casing 12.

[0077] It is understandable that when all the spray nozzles 321 spray water, they will exert a force on the spray assembly 33 in the opposite direction to the spray direction. This force will drive the spray assembly 33 to rotate circumferentially along the water passage mechanism 1. The second water passage component 142 will rotate synchronously relative to the first connecting component 143 under the drive of the spray assembly 33. The second connecting component 13 will also rotate synchronously relative to the outer casing 12 under the drive of the spray assembly 33. In this way, the comprehensive cleaning of the inner wall of the pipe can be effectively achieved.

[0078] The specific number of support components 22 is not limited. In some embodiments, please refer to... Figure 5 and Figure 6The support mechanism 2 includes two support components 22, which are arranged at an included angle.

[0079] Both support components 22 include a first support rod 221 and a second support rod 222. One end of the first support rod 221 of the two support components 22 is connected to the water passage mechanism 1 and intersecting with it. The other end of the first support rod 221 of the two support components 22 can be telescopically inserted into one end of the corresponding second support rod 222. The end of the second support rod 222 of the two support components 22 that is away from the first support rod 221 is connected to a first roller 21.

[0080] Understandably, the two support components 22 are set at an angle so that when the automatic inner wall cleaning device is installed inside the pipe, both support components 22 can be supported between the inner wall of the pipe and the water passage mechanism 1 to ensure the stability of the automatic inner wall cleaning device assembly.

[0081] During the actual operation of the automatic inner wall cleaning device, the user can control the first support rod 221 to move relative to the second support rod 222 according to the actual size of the inner diameter of the pipe, so as to adjust the overall length of the support assembly 22 until the first roller 21 is in contact with the inner wall of the pipe. In this way, the support assembly 22 can be supported between the water passage mechanism 1 and the inner wall of the pipe, and the first roller 21 can be controlled to roll on the inner wall of the pipe along the axial direction of the pipe when water is sprayed from the spray nozzle 321, so as to ensure the stability of the assembly of the automatic inner wall cleaning device.

[0082] In some embodiments, see Figure 5 and Figure 6 The support mechanism 2 also includes an adjusting rod 223, a first stabilizing rod 225 and a second stabilizing rod 226. The adjusting rod 223 is arranged along the angle bisector of the angle formed by the two support components 22, and one end of the adjusting rod 223 is connected to the intersection of the two support components 22.

[0083] One end of the first stabilizer bar 225 and the second stabilizer bar 226 are respectively connected to the ends of the two second support bars 222 near the first support bar 221. The other ends of the first stabilizer bar 225 and the second stabilizer bar 226 are movably connected to the adjusting rod 223 and intersect to form an intersection point. The intersecting ends of the first stabilizer bar 225 and the second stabilizer bar 226 can be controlled to extend and retract to move the intersection point to the position on the adjusting rod 223.

[0084] Understandably, the first support rod 221, the first stabilizing rod 225, and the second stabilizing rod 226 of the two support components 22 together form a parallelogram structure. One end of the adjusting rod 223 is connected to the intersection of the first support rod 221 of the two support components 22, and the other end is connected to the intersection of the first stabilizing rod 225 and the second stabilizing rod 226, so as to divide the parallelogram structure into a triangular structure, thereby effectively enhancing the stability of the support mechanism 2.

[0085] During the actual operation of the automatic inner wall cleaning device, when the user adjusts the overall length of the support assembly 22 according to the actual size of the pipe inner diameter, the first stabilizing rod 225 and the second stabilizing rod 226 move under the drive of their corresponding second support rod 222, and the intersection point of the first stabilizing rod 225 and the second stabilizing rod 226 moves along the extension direction of the adjusting rod 223. In this way, the first support rod 221, the first stabilizing rod 225, the second stabilizing rod 226 and the adjusting rod 223 of the two support assemblies 22 can always form a stable triangular structure, thereby effectively enhancing the stability of the support mechanism 2 and ensuring the stability of the assembly of the automatic inner wall cleaning device.

[0086] In some embodiments, see Figure 5 and Figure 6 The support mechanism 2 also includes an adjusting member 23, which includes a first sleeve 231, a second sleeve 232 and a third sleeve 233. The first sleeve 231 and the second sleeve 232 are intersected and the third sleeve 233 is fixed to the intersection of the first sleeve 231 and the second sleeve 232. The first sleeve 231 and the second sleeve 232 are movably sleeved on the first stabilizing rod 225 and the second stabilizing rod 226 respectively, and the third sleeve 233 is movably sleeved on the adjusting rod 223.

[0087] Understandably, when the user adjusts the overall length of the support assembly 22 according to the actual size of the pipe's inner diameter, the first stabilizing rod 225 and the second stabilizing rod 226 move relative to the first sleeve 231 and the second sleeve 232 respectively under the drive of their corresponding second support rod 222. The third sleeve 233 also moves relative to the adjusting rod 223 along the extension direction of the adjusting rod 223 under the drive of the first stabilizing rod 225 and the second stabilizing rod 226. In this way, the first support rod 221, the first stabilizing rod 225, the second stabilizing rod 226, and the adjusting rod 223 of the two support assemblies 22 can always form a stable triangular structure, thereby effectively enhancing the stability of the support mechanism 2 and ensuring the stability of the assembly of the automatic inner wall cleaning device.

[0088] In some embodiments, see Figure 5 and Figure 6The support mechanism 2 also includes a fixing pin 24, and the adjusting rod 223 is provided with a plurality of pin holes 224 at intervals. The third sleeve 233 is provided with a mating hole. The third sleeve 233 can be controlled to move relative to the adjusting rod 223 until the mating hole is aligned with any pin hole 224. The fixing pin 24 passes between the mating hole and the aligned pin hole 224.

[0089] The specific number of support mechanisms 2 is not limited. In some embodiments, please refer to... Figure 2 The automatic inner wall cleaning device includes at least two support mechanisms 2, which are spaced apart from each other on the water-passing mechanism 1. It can be understood that by setting multiple support mechanisms 2, the automatic inner wall cleaning device can form multiple support points on the inner wall of the pipe, so as to ensure that the automatic inner wall cleaning device can be balanced by force when moving on the inner wall of the pipe, thereby effectively improving the stability of the assembly of the automatic inner wall cleaning device.

[0090] In some embodiments, see Figure 1 and Figure 6 The automatic cleaning device for the inner wall also includes a stirring mechanism 4. The stirring mechanism 4 includes a main rod 41 and several stirring groups 42. Each stirring group 42 is arranged at intervals on the main rod 41 along the axial direction. Each stirring group 42 includes several stirring parts 43 protruding from the outside of the main rod 41, and all stirring parts 43 in the same stirring group 42 are arranged at intervals along the circumference of the main rod 41.

[0091] One end of the main body is connected to the water-passing mechanism 1 and is coaxially arranged with the water-passing mechanism 1. The main body can be controlled to rotate around its own axis.

[0092] In the actual operation of the automatic inner wall cleaning device, by controlling the main body to rotate around its own axis, the main body will drive all the stirring parts 43 of the entire stirring group 42 to rotate synchronously, so as to clean the foreign objects inside the pipe through the stirring parts 43, so as to avoid the foreign objects inside the pipe from obstructing the movement of the automatic inner wall cleaning device, which is conducive to improving the cleaning efficiency of the automatic inner wall cleaning device.

[0093] In some embodiments of the water-passing assembly 14, which includes a first water-passing element 141, a second water-passing element 142, and a first connecting element 143, please refer to... Figure 1 and Figure 6 The main body is fitted to the end of the second water-passing component 142 that is away from the first connecting component 143. Thus, when all the water nozzles 321 spray water, the force generated by the water spraying causes the water spraying assembly 33 to rotate circumferentially along the water-passing mechanism 1. The second water-passing component 142 will rotate synchronously relative to the first connecting component 143 under the drive of the water spraying assembly 33. Furthermore, the second water-passing component 142 will also drive the main body to rotate synchronously, so that the main body can rotate in a controlled manner around its own axis.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
