Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dirt cleaning, and more particularly to a device for cleaning dirt on the inner wall of a pipeline system and a cleaning method thereof. Background Art

[0002] Fouling on the inner walls of pipeline systems stems from a variety of factors. Dirt and sediment formed during the transport of media can seriously impact pipeline system operation if not promptly removed. Dirt and sediment reduce the inner diameter of the pipeline, increasing fluid transport resistance, leading to increased energy consumption and reduced transport efficiency. When the dirt accumulates to a certain level, it can cause pipeline blockages, even requiring pipeline replacement and resulting in significant economic losses. Therefore, regular removal of dirt from the inner walls of pipelines is essential to ensure safe and efficient system operation.

[0003] Existing pipe cleaning devices primarily operate in two modes: the hose-type and the wheel-type. Both remove dirt from the pipe's interior by moving a nozzle and spraying water. The hose-type is only suitable for pipes with minimal dirt buildup; heavy dirt can easily cause blockage and jamming. The wheel-type is more adaptable to heavily contaminated pipes. However, when a large amount of dirt accumulates at the pipe opening, the cleaning device faces a dual challenge: first, it is difficult to enter the pipe, and second, cleaning the dirt at the opening is difficult. The wheel's movement can compress or block the dirt at the opening, resulting in incomplete cleaning.

[0004] The existing pipeline inner wall cleaning device uses scrapers separated from each other at equal distances to adjust the diameter and then extend into the pipeline for operation. However, this method still requires the scraper to be placed in the pipeline first, and a large amount of dirt accumulates at the pipeline opening. The existing method is still not suitable for cleaning pipeline dirt in this state, and the passability is poor, making it difficult to meet the cleaning needs. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a device and method for cleaning dirt on the inner wall of a pipeline system.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a device for cleaning dirt on the inner wall of a pipeline system, comprising a moving component and a spraying component, the moving component comprising a fixed pipe, the spraying component comprising a first nozzle group and a second nozzle group, the first nozzle group and the second nozzle group being respectively arranged at both ends of the fixed pipe.

[0007] A driving assembly is installed on the outer side wall of the fixed pipe and close to the first nozzle group. The driving assembly is matched and connected with the first nozzle group.

[0008] A cleaning assembly is installed at the end of the first nozzle group away from the fixed pipe. The cleaning assembly includes an adjustment mechanism connected to the side of the first nozzle group away from the fixed pipe and four groups of adaptation mechanisms hinged to one side of the adjustment mechanism. The four groups of adaptation mechanisms are arranged in a surrounding manner, and one side of the four groups of adaptation mechanisms is connected to a scraping mechanism for cleaning dirt.

[0009] The present invention is further configured as follows: the moving component also includes four groups of first hinge plates and four groups of second hinge plates that are equidistantly hinged to the outer wall of the fixed tube, the four groups of first hinge plates and the four groups of second hinge plates are arranged correspondingly, a support plate is hinged between the first hinge plate and the corresponding second hinge plate, four groups of telescopic rods are hinged to the outer wall of the fixed tube at equal distances, the four telescopic rods are corresponding to the four groups of second hinge plates, the end of the telescopic rod piston rod is hinged to the middle part of the corresponding second hinge plate, and an electric wheel is installed on the side wall of each support plate.

[0010] The present invention is further configured as follows: the first nozzle group includes a first circular water tank arranged at one end of a fixed pipe, a plurality of first nozzles are connected around the outer wall of the first circular water tank, the first nozzles are matched with the driving assembly, and the second nozzle group includes a second circular water tank arranged at the other end of the fixed pipe, a conical portion is opened on one side of the second circular water tank, and a plurality of second nozzles are connected on the side wall of the conical portion.

[0011] The present invention is further configured as follows: a water injection pipe is connected to the side of the first circular water tank close to the fixed pipe, one end of the water injection pipe is rotatably connected to a sleeve, and a side of the sleeve away from the second circular water tank belt is connected to a liquid supply pipe, and the liquid supply pipe passes through the interior of the fixed pipe and is connected to the fixed pipe.

[0013] By adopting the above technical solution, the driving component drives the first nozzle group to rotate, so that the first nozzle group sprays the dirt on the inner wall of the pipe while the moving component drives the spraying component to move synchronously, so that the cleaning liquid can impact the dirt through the high-pressure water spiral. The water flow acts on the pipe wall in the tangential direction, so that the scale is peeled off while offsetting the axial thrust, avoiding the dirt from moving and accumulating deep into the pipe. When the second nozzle group moves to the position of the dirt to be flushed off, the nozzle is tilted toward the direction of the pipe opening to impact, forming a directional water flow barrier, pushing the peeled dirt to the outside of the pipe to realize the flow direction of the dirt and cleaning liquid.

[0014] The present invention is further configured as follows: the adjustment mechanism includes a cross connected to one side of the first circular water tank, two groups of swing plates are hinged on the four extension arms of the cross, a connecting frame is provided in the middle of one side of the cross, an adjusting cylinder is installed on the connecting frame, the piston rod of the adjusting cylinder is connected to the side wall of the cross, four auxiliary plates are hinged on the outer wall of the connecting frame at equal intervals, the four auxiliary plates are respectively hinged to the middle of one group of swing plates on the four extension arms of the cross, the two groups of swing plates on the four extension arms of the cross form a group, the four groups of adaptation mechanisms are respectively hinged to the corresponding two groups of swing plates, and an active scraper is provided on the side of the adaptation mechanism away from the corresponding swing plate.

[0015] The present invention is further configured as follows: the active scraper is arranged in a trapezoidal shape, the longer side of the active scraper is arranged close to the regulating cylinder, and the sides of the four active scrapers away from the regulating cylinder are all provided with scraping blades.

[0016] By adopting the above technical solution, four groups of active scrapers arranged in a trapezoidal shape are set up to peel off layer by layer when a large amount of dirt accumulates at the opening of the circular pipe. There is no need to place the scraper in the pipe first and then scrape it, which meets the dirt removal needs of the circular pipe with different accumulation amounts of dirt. The dirt on the travel route is cleared in advance before the electric wheel enters the circular pipe, creating conditions for the smooth entry of the device into the circular pipe and subsequent comprehensive cleaning, thereby greatly improving the functionality of the device.

[0017] The present invention is further configured as follows: the four groups of adaptation mechanisms all include a plate body hinged on the corresponding two groups of swing plates, a through slot is provided on one side of the plate body, a slider is slidably connected inside the through slot, a guide hole is provided on the inner wall of the through slot and close to the side of the adjusting cylinder, a guide tube is passed through the inside of the guide hole, a spring is sleeved on the outer wall of the guide tube, the bottom end of the spring is in contact with the inner bottom wall of the through slot, one end of the guide tube passes through the corresponding slider and has a limiting hole, a connecting rod is provided inside the guide tube, one end of the connecting rod is connected to a card block, a plurality of card slots are provided on the inner side wall of the through slot, the card block passes through the inside of the limiting hole and is adapted to the card slot.

[0018] A cavity is provided on one side of the plate body close to the adjusting cylinder, the guide tube extends into the corresponding cavity and is connected to a pipe clamp, an adjusting cylinder is installed on one side of the pipe clamp, the piston rod of the adjusting cylinder is connected to the corresponding connecting rod, a multi-stage telescopic rod is installed on the inner wall of the plate body, and the piston rod of the multi-stage telescopic rod is connected to the pipe clamp through an electric clamp.

[0019] The present invention is further configured as follows: the four groups of scraping mechanisms all include auxiliary scrapers arranged in a trapezoidal shape, a placement groove is provided inside the auxiliary scraper, the corresponding active scraper is inserted into the corresponding placement groove, a mounting groove is provided on the side wall of the corresponding active scraper, a scraping cylinder is installed between the mounting groove and the inner wall of the placement groove, a wedge-shaped portion is provided on the side of the active scraper away from the corresponding slider, and a guide slope is provided on the side of the auxiliary scraper away from the auxiliary plate, and the guide slope is adapted to the wedge-shaped portion.

[0020] By adopting the above technical solution, when cleaning square pipes, the rotation speed of the cleaning component is slowed down, and the dirt at the pipe opening is first peeled off layer by layer. The connecting rod is pushed by adjusting the cylinder to disengage the card block from the slot, and the electric clamp releases the pipe clamp to release the restriction on the slider. When the active scraper moves, due to the different distances from the side wall and the diagonal to the center point of the square pipe, the slider is driven to move on the through groove to squeeze or release the spring, so that the active scraper always fits the inner wall of the pipe to ensure thorough cleaning.

[0021] When cleaning a circular pipe, the cylinder is adjusted to push the connecting rod to move, thereby adjusting the position of the connecting rod and the block, that is, the block can be retracted into the inside of the connecting rod or extended from the limit hole. When the block extends from the inside of the limit hole, the block can be inserted into the inside of the slot. In this state, the position of the slider and the active scraper can be locked, and the electric clamp can lock the pipe clamp. After the position of the active scraper is locked, the active scraper can be used to move around and scrape off the dirt on the inner wall of the circular pipe.

[0022] When the active scraper scrapes dirt from the inner wall of the square pipe, the scraping speed slows down. At this time, the scraping cylinder drives the auxiliary scraper to slide synchronously on the outside of the active scraper, so that the active scraper completes the basic scraping while the movement of the auxiliary scraper is used to perform a secondary scraping of stubborn dirt stuck on the travel route. The collaborative operation of the two scrapers effectively improves the thoroughness of cleaning the dirt on the inner wall of the pipe.

[0023] A method for cleaning dirt from the inner wall of a pipeline system, using the above-mentioned device for cleaning dirt from the inner wall of a pipeline system, comprises the following steps:

[0024] S1. Place the device at the opening of the pipeline, then control the first nozzle group and the cleaning component to rotate as a whole through the driving component, and adjust the diameter of the cleaning component to adapt to different pipeline cleaning.

[0025] S2. When cleaning a circular pipe, the cleaning component peels off the dirt at the pipe opening layer by layer and pushes forward. During the pushing process, the first nozzle group rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt adhering to the inner wall of the pipe. When the moving component moves to the position of the inner wall of the pipe, the moving component controls the opening diameter and fits with the inner wall of the pipe. In this state, the moving component can drive the cleaning device as a whole to move forward in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0026] S3. When cleaning a square pipe, the cleaning component peels off the dirt at the pipe opening layer by layer and pushes it forward. During the pushing process, the adapter mechanism is used to control the positions of the adjustment mechanism and the scraping mechanism, so that the cleaning component not only adjusts the diameter synchronously, but also can adaptively adjust the position according to the different distances between the cleaning component and the inner wall of the pipe in different directions. At the same time, the first nozzle group rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt adhered to the inner wall of the pipe. When the moving component moves to the position of the inner wall of the pipe, the moving component controls the opening diameter and fits the inner wall of the pipe. In this state, the moving component can drive the cleaning device as a whole to move forward in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0027] S4. As the moving assembly gradually advances, the second nozzle group enters the interior of the pipe, and the second nozzle group sprays cleaning liquid at an angle toward the opening of the pipe, causing the accumulated dirt to be pushed in the opposite direction of the moving assembly. After cleaning is completed, the moving assembly withdraws in the opposite direction, and the second nozzle group uses the impact of the cleaning liquid to push the accumulated dirt out of the pipe.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] (1) By setting up four sets of active scrapers in a trapezoidal shape, the device can peel off the dirt accumulated in the circular pipe opening layer by layer. There is no need to place the scraper in the pipe before scraping, which meets the dirt removal needs of the circular pipe with different accumulation amounts of dirt. The dirt on the moving path is cleared in advance before the electric wheel enters the circular pipe, creating conditions for the smooth entry of the device into the circular pipe and subsequent comprehensive cleaning, which greatly improves the functionality of the device.

[0030] (2) When cleaning square pipes, the rotation speed of the cleaning component is slowed down, and the dirt at the pipe opening is first peeled off layer by layer. The connecting rod is pushed by the adjustment cylinder to make the block disengage from the slot, and the electric clamp releases the pipe clamp to release the restriction on the slider. When the active scraper moves, due to the different distances from the side wall and the diagonal to the center point of the square pipe, the slider moves on the slot to squeeze or release the spring, so that the active scraper always fits the inner wall of the pipe to ensure thorough cleaning.

[0031] (3) When cleaning a circular pipe, adjust the cylinder to push the connecting rod to move, and then adjust the position of the connecting rod and the block, that is, the block can be retracted into the inside of the connecting rod or extended from the limit hole. When the block extends from the inside of the limit hole, the block can be inserted into the inside of the slot. In this state, the position of the slider and the active scraper can be locked, and the electric clamp can lock the pipe clamp. After the position of the active scraper is locked, the active scraper can be used to move around to scrape the dirt on the inner wall of the circular pipe.

[0032] (4) By setting up a scraping mechanism, when the active scraper scrapes the dirt on the inner wall of the square pipe, the scraping speed slows down. At this time, the scraping cylinder drives the auxiliary scraper to slide synchronously on the outside of the active scraper, so that the active scraper completes the basic scraping while the auxiliary scraper moves to perform a secondary scraping of the stubborn dirt adhering to the route. By the collaborative operation of the two scrapers, the thoroughness of cleaning the dirt on the inner wall of the pipe is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0052] See also Figures 1-10 , the present invention provides the following technical solutions:

[0053] Example 1, see Figure 1The dirt cleaning device for the inner wall of the pipeline system includes a moving component 1 and a spraying component 2. The moving component 1 includes a fixed pipe 11. The moving component 1 also includes four groups of first hinged plates 12 and four groups of second hinged plates 16 that are equidistantly hinged to the outer wall of the fixed pipe 11. The four groups of first hinged plates 12 and the four groups of second hinged plates 16 are arranged correspondingly. A support plate 13 is hinged between the first hinged plate 12 and the corresponding second hinged plate 16. Four groups of telescopic rods 15 are hinged to the outer wall of the fixed pipe 11 at an equal distance. The four telescopic rods 15 are corresponding to the four groups of second hinged plates 16. The end of the piston rod of the telescopic rod 15 is aligned with the middle of the corresponding second hinged plate 16. Hinged, an electric wheel 14 is installed on the side wall of each support plate 13, and the telescopic rod 15 is used to push the corresponding second hinge plate 16 to swing. When the second hinge plate 16 swings, the corresponding support plate 13 is pulled to move. Since the support plate 13 is also hinged through the corresponding first hinge plate 12, the support plate 13 maintains a relative horizontal state with the fixed tube 11 when being pulled, and at the same time adjusts the distance between the support plate 13 and the fixed tube 11. The electric wheel 14 on the support plate 13 is used to fit with the inner wall of the pipe, and the rotation of the electric wheel 14 can drive the mobile component 1 to move as a whole, which is convenient for the spray cleaning component 2 to clean the dirt on the inner wall of the pipe.

[0054] When the distance between the support plate 13 and the fixed pipe 11 changes, the position of the electric wheel 14 can be adjusted synchronously, thereby facilitating the mobile component 1 to adapt to pipes of different diameters.

[0055] See Figure 1 The specific structure of the spray cleaning component 2 is as follows:

[0056] See Figure 1-Figure 3 The spraying assembly 2 includes a first nozzle group 21 and a second nozzle group 22. The first nozzle group 21 and the second nozzle group 22 are respectively arranged at both ends of the fixed pipe 11. The first nozzle group 21 and the second nozzle group 22 are respectively used to spray dirt on the inner wall of the pipe. The first nozzle group 21 includes a first circular water tank 211 arranged at one end of the fixed pipe 11. The outer wall of the first circular water tank 211 is surrounded by a plurality of first nozzles 212. The first circular water tank 211 is used to store cleaning liquid and spray dirt on the inner wall of the pipe through the plurality of first nozzles 212 arranged around it. The spraying angle of the first nozzle 212 is set perpendicular to the inner wall of the pipe. Therefore, the cleaning liquid sprayed by the first nozzle 212 can flush away the dirt on the inner wall of the pipe. The flushed dirt falls to the bottom of the inner wall of the pipe and accumulates, and the dirt does not move to the inside of the pipe.

[0057] See Figure 2 and Figure 3The second nozzle group 22 includes a second circular water tank 221 arranged at the other end of the fixed pipe 11. A conical portion 222 is provided on one side of the second circular water tank 221. A plurality of second nozzles 223 are connected to the side wall of the conical portion 222. The second circular water tank 221 is used to store the cleaning liquid, and the second nozzles 223 are installed on the inclined surface of the side wall of the conical portion 222. Therefore, the second nozzles 223 are arranged at an angle and have a spraying angle with the inner wall of the pipe. After the cleaning liquid is sprayed from the second nozzle 223, it flushes the dirt on the inner wall of the pipe at an inclined angle.

[0058] The dirt flushed off the inner wall of the pipe by the first nozzle 212 first falls to the bottom of the inner wall of the pipe, and then is flushed obliquely by the second nozzle 223, causing the dirt to be flushed toward the pipe opening and pushing the peeled dirt to the outside of the pipe.

[0059] The first circular water tank 211 is connected to a water injection pipe on one side close to the fixed pipe 11, and one end of the water injection pipe is rotatably connected to a sleeve 24. The sleeve 24 is connected to a liquid supply pipe 23 on the side away from the second circular water tank 221. The liquid supply pipe 23 passes through the interior of the fixed pipe 11 and is connected to the fixed pipe 11. External cleaning liquid is supplied through the liquid supply pipe 23 and the sleeve 24, and is respectively supplied to the interior of the first circular water tank 211 and the second circular water tank 221, thereby supplying cleaning liquid to the interior of the first circular water tank 211 and the second circular water tank 221.

[0060] See Figure 1-Figure 3 A driving assembly 3 is installed on the outer wall of the fixed pipe 11 and near the first nozzle group 21. The first nozzle 212 is connected to the driving assembly 3. The driving assembly 3 is used to drive the first nozzle group 21 to rotate, so that the first nozzle group 21 sprays the dirt on the inner wall of the pipe while the moving assembly 1 drives the spraying assembly 2 to move synchronously, so that the cleaning liquid can impact the dirt through the high-pressure water flow spiral. The water flow acts on the pipe wall along the tangential direction, so that the scale is peeled off while offsetting the axial thrust, thereby preventing the dirt from moving deep into the pipe and accumulating.

[0061] See Figure 1-Figure 3 , the specific structure of the driving component 3 is as follows:

[0062] The driving assembly 3 includes a driving motor 31 installed on the outer wall of the fixed tube 11 and a driving gear 32 connected to the output end of the driving motor 31. The outer wall of the water injection pipe is sleeved with a driven gear 33, which is engaged with the driving gear 33. The driving motor 31 is used to drive the driving gear 32 to rotate, so that the driving gear 32 drives the driven gear 33, the water injection pipe and the first circular water tank 211 to rotate. The first circular water tank 211 drives the multiple first nozzles 212 to rotate around, thereby achieving the cleaning liquid passing through the high pressure The purpose of the spiral impact of water flow on dirt is that the water flow acts on the pipe wall in the tangential direction, stripping off the dirt while offsetting the axial thrust, preventing the dirt from moving deep into the pipe and accumulating. As the moving component 1 continues to move forward, the first nozzle group 21 continues to move forward to spray and wash the dirt, and the washed-off dirt falls to the bottom of the inner wall of the pipe and accumulates. When the second nozzle group 22 moves to the position of the washed-off dirt, the nozzle tilts and impacts in the direction of the pipe opening, forming a directional water flow barrier, pushing the stripped dirt to the outside of the pipe to realize the flow direction of the dirt and cleaning liquid.

[0063] See Figure 1 The end of the first nozzle group 21 away from the fixed pipe 11 is equipped with a cleaning component 4, which is used to scrape off the dirt accumulated on the inner wall of the pipe. The specific structure of the cleaning component 4 is as follows:

[0064] The cleaning component 4 includes an adjusting mechanism 41 connected to the side of the first nozzle group 21 away from the fixed pipe 11. The adjusting mechanism 41 is used to scrape dirt on the inner wall of the pipe. The adjusting mechanism 41 includes a cross 411 connected to one side of the first circular water tank 211. Two groups of swing plates 412 are hinged on the four extension arms of the cross 411. A connecting frame 414 is provided in the middle of one side of the cross 411. An adjusting cylinder 413 is installed on the connecting frame 414. The piston rod of the adjusting cylinder 413 is connected to the side wall of the cross 411. Four auxiliary plates 415 are hinged at equal distances on the outer wall of the connecting frame 414. The four auxiliary plates 415 are respectively hinged to the middle part of one group of swing plates 412 on the four extension arms of the cross 411. The two groups of swing plates 412 on the four extension arms of the cross 411 are a group, and four active scrapers 416 are provided on the side of the swing plate 412 away from the cross 411.

[0065] The adjusting cylinder 413 is used to adjust the distance between the connecting frame 414 and the cross 411. When the connecting frame 414 approaches the cross 411, the connecting frame 414 pulls the auxiliary plate 415 to swing, causing the two swing plates 412 on the same extension arm of the cross 411 to swing toward the middle of the connecting frame 414. The swing plates 412 pull the corresponding adapter mechanisms 42 and the active scrapers 416 to approach each other synchronously. Conversely, when the piston rod of the adjusting cylinder 413 is extended, the distance between the connecting frame 414 and the cross 411 increases, and the active scrapers 416 are separated synchronously, thereby adjusting the front end diameter of the cleaning component 4 to adapt to the cleaning of pipes of different diameters.

[0066] And when the cleaning component 4 extends to the inner wall of the pipe, the active scraper 416 is used to contact the inner wall of the pipe, and at the same time, the driving component 3 drives the first nozzle group 21 to rotate, and the first circular water tank 211 drives the cleaning component 4 to rotate as a whole, and the four active scrapers 416 scrape along the inner wall of the pipe synchronously, thereby scraping off the dirt. After the dirt is scraped off, the remaining dirt is flushed once by the first nozzle group 21, causing the dirt to fall to the bottom of the inner wall of the pipe and accumulate. Then, the moving component 1 is pushed forward, and the second nozzle group 22 applies an impact force to the accumulated dirt in the direction of the pipe opening, thereby moving the dirt toward the pipe opening position. When the moving component 1 withdraws in the opposite direction, the second nozzle group 22 pushes the dirt out of the pipe.

[0067] In the second embodiment, the existing pipeline inner wall cleaning device uses scrapers separated from each other at equal distances to adjust the diameter and then extend into the pipeline for operation. However, this method still requires the scraper to be placed in the pipeline first, and a large amount of dirt accumulates at the pipeline opening. The existing method is still unable to adapt to the pipeline dirt cleaning in this state, and the passability is poor, making it difficult to meet the cleaning needs.

[0068] To this end, the active scraper 416 is arranged in a trapezoidal shape, with the longer side of the active scraper 416 arranged close to the adjusting cylinder 413, and the four active scrapers 416 are all provided with scraping blades on the side away from the adjusting cylinder 413. When the four active scrapers 416 are close to each other, a conical scraping knife group is formed.

[0069] When a large amount of dirt accumulates at the opening of the circular pipe, the scraping blade group formed by the four active scrapers 416 first contacts the dirt at the opening of the circular pipe by reducing the diameter, and then drives the cleaning component 4 to rotate as a whole through the driving component 3, so that the four active scrapers 416 cooperate to drill the dirt at the opening of the circular pipe, causing the dirt at the opening of the circular pipe to be peeled off layer by layer. At the same time, the moving component 1 drives the cleaning component 4 to advance into the inside of the circular pipe. During the advancement process, the first nozzle group 21 rotates, and the cleaning liquid passes through the first circular water tank. 211 is sprayed on the inner wall of the circular pipe to wash away the dirt stuck on the inner wall of the circular pipe. When the cleaning component 4 completely enters the circular pipe, the four active scrapers 416 separate from each other and fit against the inner wall of the circular pipe. At this time, the cleaning component 4 rotates rapidly as a whole to clean the dirt on the inner wall of the circular pipe. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits against the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to continue to advance in the pipe. At the same time, the dirt in the cleaning component 4 falls to the bottom of the inner wall of the pipe and accumulates.

[0070] By setting up four groups of active scrapers 416 arranged in a trapezoidal shape, the dirt accumulated in a large amount at the opening of the circular pipe can be peeled off layer by layer. There is no need to place the scraper in the pipe first and then scrape it, which meets the dirt removal needs of the circular pipe with different accumulation amounts of dirt. The dirt on the travel route is cleared in advance before the electric wheel 14 enters the circular pipe, creating conditions for the smooth entry of the device into the circular pipe and subsequent comprehensive cleaning, thereby greatly improving the functionality of the device.

[0071] In the third embodiment, the conventional rotary scraping cleaning method is only applicable to circular pipes and has obvious adaptability limitations when facing square pipes. In the cleaning scenario of square pipes, this method may not clean completely the dead corners and stubborn stains with strong adhesion.

[0072] To this end, four groups of adapter mechanisms 42 are hinged on one side of the adjustment mechanism 41. The four groups of adapter mechanisms 42 are arranged in a circumferential manner. The four groups of adapter mechanisms 42 are respectively hinged to the corresponding two groups of swing plates 412. The active scraper 416 is installed on the side of the adapter mechanism 42 away from the corresponding swing plate 412. The adapter mechanism 42 is used to adjust the active scraper 416, so that the distances between the four active scrapers 416 relative to the center line of the cross 411 are different, thereby ensuring that the active scraper 416 maintains contact with the side wall and diagonal position of the directional pipe during the circumferential displacement, thereby achieving the purpose of thorough cleaning.

[0073] The specific structure of the adapting mechanism 42 is as follows:

[0074] The four sets of adapting mechanisms 42 all include a plate body 421 hinged on the corresponding two sets of swing plates 412, a through slot 422 is provided on one side of the plate body 421, a slider 425 is slidably connected to the inside of the through slot 422, a guide hole 426 is provided on the inner wall of the through slot 422 and close to the side of the adjusting cylinder 413, a guide tube 423 is passed through the inside of the guide hole 426, and a spring 424 is sleeved on the outer wall of the guide tube 423, the bottom end of the spring 424 is in contact with the inner bottom wall of the through slot 422, and the slider 425 can slide in the corresponding through slot 422 and the outer wall of the corresponding guide tube 423, thereby adjusting the active scraper 416 The guide tube 423 is provided with a connecting rod 4203 at one end thereof and connected to a clamping block 4202 at one end thereof. A plurality of clamping grooves 427 are provided on the inner side wall of the through groove 422. The clamping block 4202 passes through the limiting hole 4204 and matches with the clamping groove 427. The guide tube 423 can slide inside the corresponding guide hole 426. When the guide tube 423 moves downward, the guide tube 423 drives the connecting rod 4203, the clamping block 4202 and the slider 425 to move downward, thereby adjusting the position of the active scraper 416.

[0075] A cavity is provided on one side of the plate body 421 close to the adjusting cylinder 413. The guide tube 423 extends into the corresponding cavity and is connected to a pipe clamp 428. An adjusting cylinder 4201 is installed on one side of the pipe clamp 428. The piston rod of the adjusting cylinder 4201 is connected to the corresponding connecting rod 4203. A multi-stage telescopic rod 429 is installed on the inner wall of the plate body 421. The piston rod of the multi-stage telescopic rod 429 is connected to the pipe clamp 428 through an electric clamp. The adjusting cylinder 4201 is used to push the connecting rod 4203 to move, thereby adjusting the connecting rod 420 3 and the position of the card block 4202, that is, the card block 4202 can be retracted into the interior of the connecting rod 4203 or extended from the limiting hole 4204. When the card block 4202 extends from the limiting hole 4204, the card block 4202 can be inserted into the interior of the card slot 427. In this state, the position of the slider 425 and the active scraper 416 can be locked, and the electric clamp clamps and locks the pipe clamp 428. After the position of the active scraper 416 is locked, the active scraper 416 can be used to move around to scrape off the dirt on the inner wall of the circular pipe.

[0076] When cleaning a square pipe, the rotation speed of the cleaning component 4 is slowed down, and the cleaning component 4 first peels off the dirt at the pipe opening layer by layer. At the same time, the adjusting cylinder 4201 is used to push the connecting rod 4203 to move, causing the block 4202 to move out from the inside of the slot 427, and the electric clamp releases the clamping of the pipe clamp 428. At this time, the restriction on the slider 425 is released, causing the slider 425 to be free on the corresponding through slot 422.

[0077] When the active scraper 416 moves along the inner wall of the square pipe, since the distances between the side wall and the diagonal position of the directional pipe and the center point are different, when the active scraper 416 gradually moves to the side wall position of the directional pipe, the active scraper 416 drives the slider 425 to move on the corresponding through groove 422 and gradually squeezes the spring 424. When the active scraper 416 gradually moves to the diagonal position of the directional pipe, the active scraper 416 drives the slider 425 to move on the corresponding through groove 422 and gradually releases the spring 424. This setting causes the active scraper 416 to maintain a fit with the inner wall of the square pipe, ensuring thorough cleaning.

[0078] At the same time, the first nozzle group 21 rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt stuck on the inner wall of the pipe. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits with the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to advance in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0079] See Figure 6 and Figure 7 One side of the four sets of adapting mechanisms 42 is connected to a scraping mechanism 43 for cleaning dirt. The four sets of scraping mechanisms 43 all include an auxiliary scraper 431 arranged in a trapezoidal shape. A placement groove 432 is provided inside the auxiliary scraper 431. The corresponding active scraper 416 is inserted into the corresponding placement groove 432. The side wall of the corresponding active scraper 416 is provided with a mounting groove 433. A scraping cylinder 434 is installed between the mounting groove 433 and the inner wall of the placement groove 432. A wedge-shaped portion 435 is provided on the side of the active scraper 416 away from the corresponding slider 425. A guide slope is provided on the side of the auxiliary scraper 431 away from the auxiliary plate 415, and the guide slope is adapted to the wedge-shaped portion 435.

[0080] During the process of the active scraper 416 scraping dirt off the inner wall of the square pipe, the scraping speed of the active scraper 416 is slowed down, and the auxiliary scraper 431 is driven to slide on the outside of the active scraper 416 through the scraping cylinder 434, so that the active scraper 416 completes the basic cleaning and scraping of dirt while using the auxiliary scraper 431 to move and scrape off the stubborn dirt stuck on the path of the active scraper 416, further improving the thoroughness of the cleaning effect.

[0081] Example 4, a method for cleaning dirt on the inner wall of a pipeline system, using the above-mentioned device for cleaning dirt on the inner wall of a pipeline system, includes the following steps:

[0082] S1. Place the device at the opening of the pipeline, then control the first nozzle group 21 and the cleaning component 4 to rotate as a whole through the driving component 3, and adjust the diameter of the cleaning component 4 to adapt to different pipeline cleaning.

[0083] The more specific steps of S1 are:

[0084] S11. Place the device at the opening of the pipe, then start the drive motor 31. The drive motor 31 drives the driving gear 32 to rotate, causing the driving gear 32 to drive the driven gear 33, the water injection pipe and the first circular water tank 211 to rotate. The first circular water tank 211 drives the multiple first nozzles 212 to rotate around. At this time, the liquid supply pipe 23 supplies the cleaning liquid into the sleeve 24, the water injection pipe and the first circular water tank 211 for standby use.

[0085] S12. When the first circular water tank 211 rotates, it drives the cleaning component 4 to rotate as a whole. At this time, the piston rod of the regulating cylinder 413 contracts, and the connecting frame 414 approaches the direction of the cross 411. The connecting frame 414 pulls the auxiliary plate 415 to swing, causing the two swinging plates 412 on the same extension arm of the cross 411 to swing toward the middle of the connecting frame 414. The swinging plates 412 pull the corresponding adapter mechanism 42 and the active scraper 416 to move synchronously close to each other, thereby adjusting the front end diameter of the cleaning component 4 to adapt to the cleaning of different pipes.

[0086] S2. When cleaning a circular pipe, the cleaning component 4 peels off the dirt at the pipe opening layer by layer and pushes it forward. During the pushing process, the first nozzle group 21 rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt stuck to the inner wall of the pipe. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits with the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to move forward in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0087] The more specific steps of S2 are:

[0088] S21. When cleaning a circular pipe, the cleaning component 4 first contacts the dirt at the opening of the circular pipe by reducing its diameter, and then drives the cleaning component 4 to rotate as a whole through the driving component 3, so that the four active scrapers 416 cooperate to drill the dirt at the opening of the circular pipe, causing the dirt at the opening of the circular pipe to be peeled off layer by layer. At the same time, the moving component 1 drives the cleaning component 4 to advance into the inside of the circular pipe.

[0089] S22. During the propulsion process, the first nozzle group 21 rotates, and the cleaning liquid is sprayed onto the inner wall of the circular pipe through the first circular water tank 211, washing away the dirt adhered to the inner wall of the circular pipe. When the cleaning component 4 completely enters the interior of the circular pipe, the four active scrapers 416 separate from each other and adhere to the inner wall of the circular pipe. At this time, the cleaning component 4 rotates rapidly as a whole to clean the dirt on the inner wall of the circular pipe.

[0090] S23. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits with the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to continue to advance in the pipe, and at the same time, the dirt of the cleaning component 4 falls to the bottom of the inner wall of the pipe and accumulates.

[0091] S3. When cleaning a square pipe, the cleaning component 4 peels off the dirt at the pipe opening layer by layer and pushes it forward. During the pushing process, the adaptor mechanism 42 is used to control the position of the adjusting mechanism 41 and the scraping mechanism 43, so that the cleaning component 4 not only adjusts the diameter synchronously, but also can adaptively adjust the position according to the different distances between the cleaning component 4 and the inner wall of the pipe in different directions. At the same time, the first nozzle group 21 rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt adhered to the inner wall of the pipe. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits into the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to move forward in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0092] The more specific steps for S3 are:

[0093] S31. When cleaning a square pipe, the rotation speed of the cleaning component 4 is slowed down, and the cleaning component 4 first peels off the dirt at the pipe opening layer by layer. During the pushing process, the auxiliary scraper 431 is driven by the scraping cylinder 434 to slide on the outside of the active scraper 416, so that the active scraper 416 completes the basic cleaning and scraping of dirt while using the auxiliary scraper 431 to move and remove the stubborn dirt adhering to the path of the active scraper 416.

[0094] S32. At the same time, the adjusting cylinder 4201 is used to push the connecting rod 4203 to move, causing the clamping block 4202 to move out from the inside of the clamping slot 427, and the electric clamp releases the clamping of the pipe clamp 428. At this time, the restriction on the slider 425 is released, causing the slider 425 to be free on the corresponding through slot 422.

[0095] S33. When the active scraper 416 moves along the inner wall of the square pipe, since the distances between the side wall and the diagonal position of the directional pipe and the center point are different, when the active scraper 416 gradually moves to the side wall position of the directional pipe, the active scraper 416 drives the slider 425 to move on the corresponding through groove 422 and gradually squeezes the spring 424. When the active scraper 416 gradually moves to the diagonal position of the directional pipe, the active scraper 416 drives the slider 425 to move on the corresponding through groove 422 and gradually releases the spring 424. This setting , causing the active scraper 416 to maintain a fit with the inner wall of the square pipe, and the active scraper 416 cooperates with the corresponding auxiliary scraper 431 to ensure that the dirt is thoroughly cleaned. At the same time, the first nozzle group 21 rotates and sprays the cleaning liquid on the inner wall of the pipe to wash away the dirt adhered to the inner wall of the pipe. When the moving component 1 moves to the position of the inner wall of the pipe, the moving component 1 controls the opening diameter and fits with the inner wall of the pipe. In this state, the moving component 1 can drive the cleaning device as a whole to advance in the pipe, and the dirt falls to the bottom of the inner wall of the pipe and accumulates.

[0096] S4. As the moving component 1 gradually advances, the second nozzle group 22 enters the interior of the pipe, and the second nozzle group 22 sprays cleaning liquid at an angle toward the opening of the pipe, causing the accumulated dirt to be pushed in the opposite direction of the moving component 1. After cleaning is completed, the moving component 1 withdraws in the opposite direction, and the second nozzle group 22 uses the impact of the cleaning liquid to push the accumulated dirt out of the pipe.

[0097] The more specific steps of S4 are:

[0098] S41. As the moving component 1 is gradually advanced, the second nozzle group 22 enters the interior of the pipeline, and the cleaning liquid enters the interior of the second circular water tank 221 through the liquid supply pipe 23, and is sprayed through multiple inclined second nozzles 223 arranged on the conical part 222. The cleaning liquid is sprayed obliquely toward the opening position of the pipeline, causing the accumulated dirt to be pushed in the opposite direction of the moving component 1. After cleaning is completed, the moving component 1 withdraws in the opposite direction, and the cleaning liquid sprayed by the second nozzle 223 uses the impact force to push the accumulated dirt out of the pipeline.

[0099] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
