[0001] This utility model relates to the field of pipeline cleaning technology, specifically a pipeline inner wall cleaner. Background Technology

[0002] Municipal water supply and drainage refers to a series of engineering facilities and related systems constructed and operated in cities to meet the water needs of residents, industrial production, public services, and to discharge and treat sewage and rainwater. It is an important component of urban infrastructure. The cleaning and maintenance of municipal water supply and drainage pipelines is a key task to ensure the normal operation of urban water supply and drainage systems.

[0003] The existing patent document with authorization announcement number CN221773080U describes a pipe inner wall cleaner: it includes a cutter disc, the surface of which has a cutter mounting groove, the back of which has an output end and a motor, and a plastic cleaning module is mounted on the outer curved surface of the cutter disc. A cutter and a rotating shaft are housed in the cutter mounting groove. This technical solution uses the plastic cleaning module mounted on the outer curved surface of the cutter disc; as the cutter disc rotates, it carries the plastic cleaning module along with it, thus cleaning the inner wall of the pipe and removing deposits. However, the rotating cutter disc cannot perfectly match the circular contour of the pipe inner wall during cleaning, and prolonged use can damage the inner wall of the pipe. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a pipe inner wall cleaner that solves the problem that the rotating blade cannot match the circular contour of the pipe inner wall during cleaning, which can cause damage to the pipe inner wall after long-term use. When cleaning the pipe, as the cleaner advances, the scraping blade contacts the pipe inner wall with its arc-shaped surface, which can evenly distribute the scraping force on the pipe inner wall and avoid excessive local pressure that could damage the pipe inner wall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe inner wall cleaner, comprising a drive assembly, a propulsion assembly, a cleaning assembly, and a scraping assembly. The drive assembly includes a drive tube, the propulsion assembly includes a propulsion tube and a second motor, the cleaning assembly includes a second telescopic rod, a positioning plate, and a third telescopic rod, and the scraping assembly includes a scraping blade and a scraping plate. A first telescopic rod is connected to the outer circumferential wall of the drive tube, and a wheel frame is connected to the output end of the first telescopic rod away from the drive tube. A traveling wheel is connected to the inner side of the wheel frame via a bearing drive, and a first motor is connected to one end of the wheel frame. A rotating shaft is connected to the inner side of the propulsion tube, and a sleeve is fitted around the outer ring of one end of the rotating shaft. A pulverizing blade integrally formed therewith is provided on the outer circumferential wall of the sleeve. A cleaning brush is connected to one end of the positioning plate, and the scraping plate includes a scraping cone.

[0006] The beneficial effects of this utility model are as follows: During use, the scraping blade adheres to the inner wall of the pipe under the action of the connected third telescopic rod. The cutting edge of the scraping blade is arc-shaped, which is used to match the circular contour of the inner wall of the pipe. During the cleaning process, it closely adheres to the inner wall of the pipe, ensuring the comprehensiveness and thoroughness of the cleaning and reducing cleaning dead corners. When cleaning the pipe, as the cleaner advances, the scraping blade contacts the inner wall of the pipe with its arc-shaped surface, which can evenly distribute the scraping force on the inner wall of the pipe, avoiding excessive local pressure that could damage the inner wall of the pipe.

[0007] In order for the first telescopic rod to work and for the traveling wheels to be close to the inner wall of the pipe:

[0008] As a further improvement to the above technical solution: a traction rope is connected to the outer wall of the end of the drive tube away from the propulsion tube, and four first telescopic rods are installed on the outer wall of the circumference of the propulsion tube at equal intervals. The first telescopic rods are electrically connected to the operation panel.

[0009] The beneficial effects of this improvement are as follows: When in use, the cleaner is pushed into the pipe, the operation of the first telescopic rod is started, the first telescopic rod works and brings the traveling wheel close to the inner wall of the pipe, until the traveling wheel is in contact with the inner wall of the pipe.

[0011] As a further improvement to the above technical solution: the second motor is installed inside the propulsion tube and electrically connected to the operation panel, and the end of the rotating shaft away from the sleeve tube passes through the wall of the propulsion tube and is connected to the output end of the second motor through a coupling.

[0012] The beneficial effects of this improvement are: starting the second motor, the second motor works and drives the rotating shaft to rotate, thereby realizing the rotation of the propulsion tube and the sleeve tube through the rotation of the rotating shaft.

[0013] In order to break up the sludge buildup inside the pipe by using a propulsion drill and the rotation of the shredder:

[0014] As a further improvement to the above technical solution: the sleeve is fitted onto the outer ring of the rotating shaft and connected to the rotating shaft by bolts, and a propulsion drill is welded to one end of the sleeve.

[0015] The beneficial effects of this improvement are as follows: when the rotating shaft rotates, it drives the sleeve to rotate, and then the rotating of the propulsion drill and the crushing blade breaks up the sludge in the pipe, which facilitates the subsequent cleaning of the inner wall of the pipe.

[0016] To achieve a cyclical operation of scraping and cleaning the dirt on the inner wall of the pipe:

[0017] As a further improvement to the above technical solution: there are four second telescopic rods, which are symmetrically installed on the outer wall of the circumference of the propulsion tube. The second telescopic rods are electrically connected to the operation panel, and the end of the second telescopic rod away from the propulsion tube is connected to the positioning plate.

[0018] The beneficial effects of this improvement are as follows: After the push tube is pushed into the pipe, the second and third telescopic rods are activated. The second and third telescopic rods extend and drive the connected positioning plate, scraping blade, and scraping plate to move until the bristles of the cleaning brush are in contact with the inner wall of the pipe. During the rotation of the push tube, the cleaning brush is driven to rotate on the inner wall of the pipe through the second telescopic rod. During the rotation, the cleaning brush cleans the dirt scraped off the inner wall of the pipe. Through the coordinated use of the cleaning brush and the scraping components, a cyclical operation of scraping and cleaning dirt off the inner wall of the pipe is achieved, ensuring the effectiveness of pipe dredging.

[0019] In order for the first motor to work and drive the traveling wheels to move forward inside the pipe:

[0020] As a further improvement to the above technical solution: the first motor is electrically connected to the operation panel, and the inner side of the walking wheel is provided with a rotating shaft connected to the output end of the first motor.

[0021] The beneficial effects of this improvement are as follows: after the four wheels are simultaneously in contact with the inner wall of the pipe, the first motor is started, and the first motor works to drive the wheels forward in the pipe, thereby enabling the device to move inside the pipe.

[0022] In order to distribute the scraping force evenly on the inner wall of the pipe and avoid excessive local pressure that could damage the inner wall of the pipe:

[0023] As a further improvement to the above technical solution: the scraping blade is connected to the output end of the third telescopic rod through the mounting base, the third telescopic rod is electrically connected to the operation panel, and the side of the scraping blade away from the mounting base is set with an arc-shaped structure.

[0024] The beneficial effects of this improvement are as follows: During use, the scraping blade, under the action of the connected third telescopic rod, fits against the inner wall of the pipe. The cutting edge of the scraping blade is arc-shaped, which matches the circular contour of the inner wall of the pipe. During the cleaning process, it fits tightly against the inner wall of the pipe, ensuring the comprehensiveness and thoroughness of the cleaning and reducing cleaning dead corners. When cleaning the pipe, as the cleaner advances, the scraping blade contacts the inner wall of the pipe with its arc-shaped surface, which can evenly distribute the scraping force on the inner wall of the pipe, avoiding excessive local pressure that could damage the inner wall of the pipe.

[0025] To achieve dual scraping of deposits on the inner wall of the pipe using both a scraping blade and a scraping plate:

[0026] As a further improvement to the above technical solution: there are two third telescopic rods, which are symmetrically installed on the outer wall of the circumference of the propulsion tube. The scraper is connected to the output end of the third telescopic rod through the mounting seat. The side of the scraper away from the mounting seat is set with an arc-shaped structure.

[0027] The beneficial effects of this improvement are as follows: after the scraper blade approaches the inner wall of the pipe under the drive of the third telescopic rod, the push pipe rotates and drives the corresponding scraping blade and scraper blade to rotate on the inner wall of the pipe through the third telescopic rod. During the rotation, the scraper blade scrapes off the dirt on the inner wall of the pipe through the scraping cone. Then, the scraping blade and scraper blade achieve dual scraping of the deposits on the inner wall of the pipe, ensuring the effect of unblocking the pipe. Attached Figure Description

The drive assembly 1 includes a drive pipe 11; the propulsion assembly 2 includes a propulsion pipe 21 and a second motor 22; the cleaning assembly 3 includes a second telescopic rod 31, a positioning plate 32, and a third telescopic rod 34; the scraping assembly 4 includes a scraping blade 41 and a scraping plate 42. A first telescopic rod 13 is connected to the outer circumferential wall of the drive pipe 11. A wheel frame 14 is connected to the output end of the first telescopic rod 13 away from the drive pipe 11. A traveling wheel 15 is connected to the inner side of the wheel frame 14 via a bearing drive. One end of the wheel frame 14 is connected to a first motor 12. A rotating shaft 23 is connected to the inner side of the propulsion tube 21. A sleeve 24 is fitted around the outer ring of one end of the rotating shaft 23. A pulverizing blade 26 integrally formed with the sleeve 24 is provided on the outer wall of its circumferential surface. One end of the positioning plate 32 is connected to a cleaning brush 33. The scraper 42 includes a scraping cone 421. A traction rope is connected to the outer wall of the end of the drive tube 11 away from the propulsion tube 21. Four first telescopic rods 13 are installed circumferentially at equal intervals on the outer wall of the propulsion tube 21. The first telescopic rods 13 are electrically connected to the operation panel. In use, the cleaning... Inside the processor's propulsion pipe, the first telescopic rod 13 is activated, causing it to operate and bring the traveling wheel 15 close to the inner wall of the pipe until it is in contact with the inner wall. The second motor 22 is installed inside the propulsion tube 21 and electrically connected to the control panel. The end of the rotating shaft 23 away from the sleeve 24 penetrates the wall of the propulsion tube 21 and is connected to the output end of the second motor 22 via a coupling. The second motor 22 is activated, causing it to operate and drive the rotating shaft 23 to rotate. This rotation of the rotating shaft 23 then rotates both the propulsion tube 21 and the sleeve 24. The sleeve 24 is sleeved on the outer ring of the rotating shaft 23 and connected to the rotating shaft 23 by bolts. One end of the sleeve 24 is welded with a push drill 25. When the rotating shaft 23 rotates, the rotating shaft 23 drives the sleeve 24 to rotate, and then the push drill 25 and the crusher 26 rotate to break up the sludge in the pipe, which facilitates the subsequent cleaning of the inner wall of the pipe. There are four second telescopic rods 31, which are symmetrically installed on the outer wall of the push tube 21. The second telescopic rods 31 are electrically connected to the operation panel. The end of the second telescopic rod 31 away from the push tube 21 is connected to the positioning plate 32.After the push tube 21 is pushed into the pipe, the second telescopic rod 31 and the third telescopic rod 34 are activated. The second telescopic rod 31 and the third telescopic rod 34 extend and drive the connected positioning plate 32, scraping blade 41, and scraping plate 42 to move until the bristles of the cleaning brush 33 are in contact with the inner wall of the pipe. During the rotation of the push tube 21, the second telescopic rod 31 drives the cleaning brush 33 to rotate on the inner wall of the pipe. During the rotation, the cleaning brush 33 scrapes away the dirt on the inner wall of the pipe. Through the cooperation of the cleaning brush 33 and the scraping component 4, the dirt on the inner wall of the pipe is effectively removed. The cyclical scraping and cleaning operation ensures effective pipe unblocking. The first motor 12 is electrically connected to the control panel. The inner side of each of the traveling wheels 15 has a rotating shaft connected to the output end of the first motor 12. After all four traveling wheels 15 are simultaneously pressed against the inner wall of the pipe, the first motor 12 is started. The first motor 12 operates, driving the traveling wheels 15 forward within the pipe, thus enabling the device to move within the pipe. The scraping blade 41 is connected to the output end of the third telescopic rod 34 via a mounting base 43. The third telescopic rod 34 is electrically connected to the control panel. The scraping blade 41 is located away from the mounting base 43. One side features an arc-shaped structure. During use, the scraping blade 41, under the action of the connected third telescopic rod 34, adheres to the inner wall of the pipe. The arc-shaped cutting edge of the scraping blade 41 matches the circular contour of the pipe's inner wall, ensuring a tight fit during cleaning and guaranteeing comprehensive and thorough cleaning, reducing blind spots. As the cleaner advances, the scraping blade 41, with its arc-shaped surface, contacts the inner wall of the pipe, evenly distributing the scraping force across the inner wall and preventing damage from excessive local pressure. Two third telescopic rods 34 are symmetrically installed on the circumference of the push tube 21. On the outer wall, the scraper 42 is connected to the output end of the third telescopic rod 34 via the mounting base 43. The side of the scraper 42 away from the mounting base 43 has an arc-shaped structure. After the scraper 42 approaches the inner wall of the pipe under the drive of the third telescopic rod 34, the push tube 21, during its rotation, drives the corresponding scraper blade 41 and scraper 42 to rotate on the inner wall of the pipe via the third telescopic rod 34. During rotation, the scraper 42 scrapes off the dirt on the inner wall of the pipe through the scraper cone 421. Thus, the scraper blade 41 and scraper 42 achieve dual scraping of the deposits on the inner wall of the pipe, ensuring effective pipe unblocking.

[0036] The working principle of this utility model is as follows: During use, the cleaner is pushed into the pipe, and the first telescopic rod 13 is activated. The first telescopic rod 13 operates, bringing the traveling wheel 15 close to the inner wall of the pipe until it is in contact with the inner wall. The first motor 12 is then activated, driving the traveling wheel 15 forward within the pipe. After the push tube 21 is pushed into the pipe, the second telescopic rod 31 and the third telescopic rod 34 are activated. The second and third telescopic rods 31 and 34 extend, driving the connected positioning plate 32, scraping blade 41, and scraping plate 4. 2. Move the cleaning brush 33 until its bristles are in contact with the inner wall of the pipe. When the rotating shaft 23 rotates, it drives the sleeve 24 to rotate, which in turn breaks up the sludge and clumps in the pipe through the rotation of the push drill 25 and the shredder 26, facilitating subsequent cleaning of the inner wall of the pipe. Start the second motor 22, which drives the rotating shaft 23 to rotate. The rotation of the rotating shaft 23 then causes the push tube 21 and the sleeve 24 to rotate. During the rotation of the push tube 21, the cleaning brush 33 is driven by the second telescopic rod 31 to move inside the pipe. The cleaning brush 33 scrapes away dirt from the inner wall of the pipe as it rotates along the wall. The combined use of the cleaning brush 33 and the scraping component 4 achieves a cyclical scraping and cleaning operation, ensuring effective pipe unblocking. The scraping blade 41, under the action of the connected third telescopic rod 34, adheres to the inner wall of the pipe. The curved edge of the scraping blade 41 matches the circular contour of the inner wall, ensuring a close fit during cleaning and guaranteeing thoroughness and minimizing blind spots. As the cleaner advances, the scraper... The cutting edge 41, with its arc-shaped surface, contacts the inner wall of the pipe, which can evenly distribute the scraping force on the inner wall of the pipe, avoiding excessive local pressure that could damage the inner wall of the pipe. After the scraper plate 42 approaches the inner wall of the pipe under the drive of the third telescopic rod 34, the push tube 21 rotates, which in turn drives the corresponding scraper edge 41 and scraper plate 42 to rotate on the inner wall of the pipe through the third telescopic rod 34. During the rotation, the scraper plate 42 scrapes off the dirt on the inner wall of the pipe through the scraper cone 421. Thus, the scraper edge 41 and scraper plate 42 achieve dual scraping of the deposits on the inner wall of the pipe, ensuring the effect of unblocking the pipe.
