Description

Technical Field

[0001] The invention relates to the technical field of pipe cleaning, in particular to an internal cleaning device for a steel wire mesh skeleton pipe. Background Art

[0002] Steel wire mesh skeleton polyethylene composite pipe is a new type of pipe that uses a mesh skeleton formed by spirally winding high-strength steel wire as a reinforcement, high-density polyethylene (HDPE) as a matrix, and high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene.

[0003] Wire mesh reinforced polyethylene composite pipe utilizes high-quality materials and advanced production processes, resulting in higher pressure resistance. Furthermore, this composite pipe exhibits excellent flexibility, making it suitable for long-distance buried water and gas pipeline systems. The fittings used for this pipe are polyethylene electrofusion fittings. During connection, the heating element within the fitting fuses the outer plastic layer of the pipe with the inner plastic layer of the fitting, reliably connecting the pipe and fitting.

[0004] At present, after the wire mesh skeleton pipe is processed, its surface and inner wall will be more or less sticky with dust during the subsequent transportation and storage. If the dust is not removed in time, the dust on the surface of the pipe is easy to clean, but the dust on the inner wall of the pipe is difficult to clean. Summary of the Invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a wire mesh skeleton pipe internal cleaning device, comprising a motor, an output end of the motor is fixedly connected to an extension rod, the surface of the extension rod is fixedly connected to a friction pusher, the surface of the friction pusher is sleeved with a sleeve plate, the outer surface of the sleeve plate is fixedly connected to a fitting frame on both sides, the surface of the fitting frame is rotatably connected to a rotating support, the outer surface of the rotating support is fixedly connected to an extrusion bent plate, the extrusion bent plates are provided with two groups, the two groups of extrusion bent plates are symmetrical with the rotating support as the center, and a cleaning component is fixedly connected between the opposite surfaces of the extrusion bent plates; The workers use a clamp to clamp and fix the wire mesh skeleton pipe, and then pass the cleaning device through the inside of the wire mesh skeleton pipe. When the cleaning device is placed inside the pipe, the cleaning component is affected by the shape of the pipe and squeezed with the inner wall of the pipe. The cleaning components on both sides gather toward the turning bead, and make the cleaning scraper slide on the surface of the extrusion bent plate, and squeeze the extrusion bent plate when gathering toward the middle, so that the bending angle of the extrusion bent plate changes, which makes it easier for the cleaning scraper to fit the inner wall of the pipe. Then the staff starts the motor, so that the motor drives the extension rod to rotate and drives the deformed cleaning component to rotate in the pipe to clean the pipe.

[0006] The rotating support member includes a top support frame, wherein both sides of the outer surface of the top support frame are fixedly connected with an extrusion bent plate, the surface of the top support frame is slidably connected with a slide rod, the surface of the slide rod is fixedly connected with a rotating ball, the outer surface of the rotating ball is fixedly connected with a side clamp frame, the surface of the rotating ball away from the slide rod is fixedly connected with a pressure rod, and the surface of the pressure rod is slidably connected with an anti-damage support. The top support frame and the anti-damage support are respectively arranged at both ends of the rotating ball. When the cleaning device is placed inside the pipe fitting, due to the different models and thicknesses of the pipe fittings, the inner wall of the pipe fitting squeezes the top support frame, the anti-damage support and the cleaning component, so that the top support frame, the anti-damage support and the cleaning component fit the inner wall of the pipe fitting. Since the surface of the extension rod is provided with a friction pusher, the extension rod drives the friction pusher to rotate. Since the sleeve plate is connected to the fitting frame, the rotating ball and the friction pusher are simultaneously driven by the extension rod to rotate inside the pipe fitting to clean the pipe wall.

[0007] Preferably, the support assembly includes a connecting seat, with outer plates fixedly connected to both sides of the outer surface of the connecting seat, and a spring seat fixedly connected to the inner surface of the connecting seat. A friction plate is provided in the gap between the spring seat and the connecting seat. Two friction plates are provided, symmetrical with the spring seat as the center, and fixedly connected to the surface of the spring seat. The spring seat is made of elastic material. When the cleaning device is placed in the pipe, the friction plate is squeezed by the pipe wall to squeeze the spring seat. The connecting seat is slidably connected to the surface of the slide rod. The friction plate fits the surface of the pipe and can be supported on the inner wall of the pipe when cleaning the pipe, thereby improving the stability of the cleaning blade when rotating during cleaning.

[0008] Preferably, the side clamping frame includes a connecting seat, two of which are provided, and the two connecting seats are symmetrical with the rotating bead as the center. A retractable rod is fixedly connected to the surface of the connecting seat, and a first clamping plate is fixedly connected to the surface of the retractable rod. When the cleaning components on both sides are squeezed by the pipe wall and gathered towards the middle, the inner push frames on both sides are displaced towards the middle, so that the inner push frames and the side clamping frames are squeezed, and the first clamping plate and the second clamping plate are displaced by the influence of the pipe wall. Since the first clamping plate and the second clamping plate are arranged opposite to each other, and the second clamping plate is arranged crosswise with the first clamping plate, the side clamping frame limits the inner push frames, fixes the extrusion bent plate when cleaning the pipe wall, and prevents the position of the extrusion bent plate from loosening during cleaning, causing jamming during cleaning.

[0009] Preferably, the anti-damage support includes a shell, a base is fixedly connected to the surface of the shell, an elastic rod is fixedly connected to the surface of the base, side support flaps are rotatably connected to both sides of the outer surface of the base, and the surface of the side support flaps is fixedly connected to limit plates, and the limit plates are adapted to the shell. The shell is connected to the surface of the pressure rod, and the elastic rod is supported on the inner wall of the pipe. The elastic rod is made of a flexible material. When the elastic rod is squeezed and contracted by the inner wall, the side support flaps contact the pipe wall and rotate on the surface of the base due to the shape, flipping upward to support the anti-damage support on the surface of the pipe wall, avoiding poor fixing effect of the squeezed bent plate during cleaning, resulting in collision with the pipe and damage to the pipe.

[0010] Preferably, the cleaning assembly includes two sets of liquid storage tanks, each symmetrically arranged around the rotating bead. Cleaning blades are provided on both sides of the outer surfaces of the liquid storage tanks, and the cleaning blades are slidably connected to the surface of the extruded curved plate. The liquid storage tanks are filled with cleaning liquid, which flows through the delivery pipe into the connecting pipe and is sprayed onto the interior of the pipe through the spray pipe, providing a sufficient water source during cleaning to facilitate the removal of dust from the pipe interior.

[0011] Preferably, a slot is provided on the surface of the liquid storage box, a delivery pipe is fixedly connected to the surface of the slot, a connecting pipe is fixedly connected to the inner surface of the delivery pipe, a spray pipe is fixedly connected to the surface of the connecting pipe, and an inner push frame is fixedly connected to the outer surface of the slot.

[0012] Preferably, the inner push frame includes a fixed plate, a push rod is fixedly connected to the middle of the outer surface of the fixed plate, and a second clamping plate is slidably connected to the surface of the push rod, and the second clamping plate is adapted to the first clamping plate. The second clamping plate is slidably connected to the surface of the push rod. When the second clamping plate contacts and squeezes the first clamping plate, the second clamping plate and the first clamping plate squeeze and drive the push rod to slide on the surface of the fixed plate, and stop sliding when sliding to the surface of the limit ring. When cleaning the pipe fittings, the size can be adjusted according to the pipe diameter to clean pipe fittings of different models.

[0013] Preferably, a limiting ring is fixedly connected to the side of the outer surface of the fixing plate, and four limiting rings are provided, and the four limiting rings are symmetrical with the push rod as the center.

[0014] Preferably, the friction pusher comprises a connecting rotating ball, the surface of which is fixedly connected to a fixed block, the surface of which is fixedly connected to a top block, the outer surface of which is slidably connected to a push rack, the outer surface of which is sleeved with a tilting shaft, and the push rack is mounted on the inner surface of the extension rod. The connecting rotating ball drives the rotating ball on the surface of the contact rack to rotate, which in turn drives the connected inner push rack and side clamp rack to rotate, thereby cleaning the pipe wall from multiple aspects.

[0015] Preferably, the ejection rack includes a clamping shaft, a connecting ring is fixedly connected to the surface of the clamping shaft, a collar is slidably connected to the surface of the connecting ring, an outer shaft is fixedly connected to the surface of the collar, a pushing shaft is fixedly connected to the inner surface of the outer shaft, and the pushing shaft is slidably connected to the outer surface of the top block. When encountering impurities that are difficult to clean during cleaning, the cleaning blade will fluctuate. Due to the contact between the connecting rotating ball and the fixed block, the top block is pushed to slide toward the surface of the ejection rack, causing the pushing shaft to push the collar to slide on the surface of the connecting ring, squeezing the flip shaft and causing it to flip. At this time, the pushing shaft extends toward the connection rotating ball to push the rotating ball, thereby increasing the cleaning force on the pipe wall.

[0016] The present invention provides a wire mesh skeleton pipe internal cleaning device. It has the following beneficial effects:

[0017] 1. The internal cleaning equipment of the wire mesh skeleton pipe will cause the cleaning scraper to fluctuate when encountering impurities that are difficult to clean during cleaning. Since the connecting rotating ball and the fixed block are against each other, the top block is pushed to slide on the surface of the push frame, so that the pushing shaft pushes the sleeve to slide on the surface of the connecting ring, squeezing the flip shaft and causing the flip shaft to flip. At this time, the pushing shaft extends toward the connecting rotating ball to push the rotating ball, thereby increasing the cleaning force on the pipe wall.

[0018] 2. The internal cleaning equipment of the wire mesh skeleton pipe is respectively arranged at both ends of the rotating bead through the top support frame and the anti-damage support. When the cleaning device is placed inside the pipe, due to the different models and thicknesses of the pipes, the inner wall of the pipe squeezes the top support frame, the anti-damage support and the cleaning component, so that the top support frame, the anti-damage support and the cleaning component fit on the inner wall of the pipe. Since the surface of the extension rod is provided with a friction pusher, the extension rod drives the friction pusher to rotate. Since the sleeve plate is connected to the fitting frame, the rotating bead and the friction pusher are simultaneously driven by the extension rod to rotate inside the pipe to clean the pipe wall.

[0019] 3. The internal cleaning equipment of the wire mesh skeleton pipe adopts an elastic material for the spring seat. When the cleaning device is placed in the pipe, the friction plate is squeezed by the pipe wall to squeeze the spring seat. The connecting seat is slidably connected to the surface of the slide rod. The friction plate fits the surface of the pipe and can be supported on the inner wall of the pipe when cleaning the pipe, thereby improving the stability of the cleaning scraper when rotating during cleaning.

[0020] 4. The internal cleaning equipment of the wire mesh skeleton pipe, when the cleaning components on both sides are squeezed by the pipe wall and gathered towards the middle, the inner push frames on both sides are displaced towards the middle, so that the inner push frames and the side clamping frames are squeezed, and the first clamping plate and the second clamping plate are displaced by the influence of the pipe wall. Since the first clamping plate and the second clamping plate are arranged opposite to each other, and the second clamping plate and the first clamping plate are arranged crosswise, the side clamping frame limits the inner push frame and fixes the extrusion bent plate when cleaning the pipe wall to avoid the position of the extrusion bent plate from loosening during cleaning, causing jamming during cleaning.

[0021] 5. The internal cleaning equipment of the wire mesh skeleton pipe is connected to the surface of the pressure rod through the shell, and the elastic rod is supported on the inner wall of the pipe. The elastic rod is made of flexible material. When the elastic rod is squeezed with the inner wall, it shrinks, causing the side support flap to contact the pipe wall and rotate on the base surface under the influence of the shape, and flip upward to support the anti-damage support on the surface of the pipe wall, avoiding poor fixing effect of the extruded bent plate during cleaning, collision with the pipe, and damage to the pipe.

[0022] 6. The internal cleaning equipment of the wire mesh skeleton pipe is connected to the surface of the push rod through a second clamping plate. When the second clamping plate is in contact with the first clamping plate, the second clamping plate and the first clamping plate squeeze and drive the push rod to slide on the surface of the fixed plate. When sliding to the surface of the limit ring, it stops sliding. When cleaning the pipe, the size is adjusted according to the pipe diameter, and different types of pipes can be cleaned.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms.

The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0033] The first embodiment, as Figure 1-Figure 3As shown, the present invention provides a technical solution: a wire mesh skeleton pipe internal cleaning device, comprising a motor 1, an extension rod 3 is fixedly connected to the output end of the motor 1, a friction pusher 4 is fixedly connected to the surface of the extension rod 3, a sleeve 2 is provided on the surface of the friction pusher 4, a laminating frame 6 is fixedly connected to the outer surface of the sleeve 2, a rotating support 7 is rotatably connected to the surface of the laminating frame 6, an extrusion bent plate 5 is fixedly connected to the outer surface of the rotating support 7, two groups of extrusion bent plates 5 are provided, the two groups of extrusion bent plates 5 are symmetrical with the rotating support 7 as the center, and a cleaning component 8 is fixedly connected between the opposite surfaces of the extrusion bent plates 5; the staff uses a clamp to clamp the wire mesh skeleton The frame pipe is clamped and fixed, and then the cleaning device is passed through the inside of the wire mesh skeleton pipe. When the cleaning device is placed inside the pipe, the cleaning component 8 is affected by the shape of the pipe and squeezed with the inner wall of the pipe. The cleaning components 8 on both sides gather toward the rotating bead 72, and make the cleaning scraper 85 slide on the surface of the extrusion bent plate 5, and squeeze the extrusion bent plate 5 when gathering toward the middle, so that the bending angle of the extrusion bent plate 5 changes, which makes it easier for the cleaning scraper 85 to fit the inner wall of the pipe. Then the staff starts the motor 1, so that the motor 1 drives the extension rod 3 to rotate and drives the deformed cleaning component 8 to rotate in the pipe to clean the pipe.

[0034] The friction pusher 4 includes a connecting rotating ball 45, the surface of which is fixedly connected to a fixed block 41, the surface of which is fixedly connected to a top block 42, the outer surface of which is slidably connected to a pusher frame 43, the outer surface of which is sleeved with a tilting shaft 44, and the pusher frame 43 is mounted on the inner surface of the extension rod 3. The connecting rotating ball 45 drives the rotating ball 72 on the surface of the fitting frame 6 to rotate, which in turn drives the connected inner pusher frame 82 and side clamping frame 73 to rotate, thereby cleaning the pipe wall from multiple aspects.

[0035] The ejection rack 43 includes a clamping shaft 435, a connecting ring 434 being fixedly connected to the surface of the clamping shaft 435, a collar 431 being slidably connected to the surface of the connecting ring 434, an outer shaft 433 being fixedly connected to the surface of the collar 431, a pushing shaft 432 being fixedly connected to the inner surface of the outer shaft 433, and a pushing shaft 432 being slidably connected to the outer surface of the top block 42. When the cleaning blade 85 encounters impurities that are difficult to clean during cleaning, it will fluctuate. As the connecting rotating ball 45 abuts against the fixed block 41, the top block 42 is pushed to slide toward the surface of the ejection rack 43, causing the pushing shaft 432 to push the collar 431 to slide on the surface of the connecting ring 434, squeezing the flip shaft 44 and causing it to flip. At this time, the pushing shaft 432 extends toward the connecting rotating ball 45 to push the rotating ball 72, thereby increasing the cleaning force on the pipe wall.

[0036] The second embodiment, as Figure 4-Figure 7As shown, the rotating support member 7 includes a top support assembly frame 71, and the extruded bent plates 5 are fixedly connected on both sides of the outer surface of the top support assembly frame 71, and the surface of the top support assembly frame 71 is slidably connected to the slide rod 75, and the surface of the slide rod 75 is fixedly connected to the rotating ball 72, and the outer surface of the rotating ball 72 is fixedly connected to the side clamping frame 73, and the surface of the rotating ball 72 away from the slide rod 75 is fixedly connected to the pressure rod 76, and the surface of the pressure rod 76 is slidably connected to the anti-damage support 74. The top support frame 71 and the anti-damage support 74 are respectively arranged at the two ends of the rotating bead 72. When the cleaning device is placed inside the pipe, due to the different models and thicknesses of the pipe, the inner wall of the pipe squeezes the top support frame 71, the anti-damage support 74 and the cleaning component 8, so that the top support frame 71, the anti-damage support 74 and the cleaning component 8 fit against the inner wall of the pipe. Since the surface of the extension rod 3 is provided with a friction pusher 4, the extension rod 3 drives the friction pusher 4 to rotate. Since the sleeve plate 2 is connected to the fitting frame 6, the rotating bead 72 and the friction pusher 4 are simultaneously driven by the extension rod 3 to rotate inside the pipe to clean the pipe wall.

[0037] The support assembly 71 includes a connecting seat 712, with outer plates 713 fixedly connected to both sides of the outer surface of the connecting seat 712. A spring seat 711 is fixedly connected to the inner surface of the connecting seat 712. A friction plate 714 is provided in the gap between the spring seat 711 and the connecting seat 712. Two friction plates 714 are provided, symmetrically centered around the spring seat 711, and fixedly connected to the surface of the spring seat 711. The spring seat 711 is made of elastic material. When the cleaning device is placed in the pipe, the friction plates 714 are squeezed by the pipe wall and squeeze the spring seat 711. The connecting seat 712 is slidably connected to the surface of the slide rod 75. The friction plates 714 are in contact with the surface of the pipe, supporting the inner wall of the pipe when cleaning the pipe, thereby improving the stability of the cleaning blade 85 during rotation.

[0038] The side clamping frame 73 includes a connecting seat 731, which is provided with two connecting seats 731. The two connecting seats 731 are symmetrical with the rotating bead 72 as the center. The surface of the connecting seat 731 is fixedly connected to the retracting rod 732, and the surface of the retracting rod 732 is fixedly connected to the first clamping plate 733. When the cleaning components 8 on both sides are squeezed by the pipe wall and gathered towards the middle, the inner push frames 82 on both sides are displaced towards the middle, so that the inner push frames 82 and the side clamping frames 73 are squeezed, and the first clamping plate 733 and the second clamping plate 821 are displaced by the pipe wall. Since the first clamping plate 733 and the second clamping plate 821 are arranged opposite to each other, and the second clamping plate 821 is arranged crosswise with the first clamping plate 733, the side clamping frame 73 limits the inner push frames 82, fixes the extrusion bent plate 5 when cleaning the pipe wall, and prevents the position of the extrusion bent plate 5 from loosening during cleaning, causing jamming during cleaning.

[0039] The anti-damage support 74 includes a shell 742, the surface of which is fixedly connected to a base 741, the surface of which is fixedly connected to an elastic rod 745, and the outer surface of the base 741 is rotatably connected to side support flaps 744 on both sides, and the surface of the side support flaps 744 is fixedly connected to a limit plate 743, which is adapted to the shell 742. The shell 742 is connected to the surface of the pressure rod 76, and the elastic rod 745 is supported on the inner wall of the pipe. The elastic rod 745 is made of a flexible material. When the elastic rod 745 is squeezed and contracted by the inner wall, the side support flaps 744 contact the pipe wall and are affected by the shape of the elastic rod 745, rotating on the surface of the base 741 and flipping upward, thereby supporting the anti-damage support 74 on the pipe wall surface, avoiding poor fixing of the extrusion bent plate 5 during cleaning, resulting in collision with the pipe and damage to the pipe.

[0040] The third embodiment, as Figure 4 、 Figure 5 and Figure 8 As shown, the cleaning assembly 8 includes two sets of liquid storage tanks 81, which are symmetrically arranged around the rotating bead 72. Cleaning blades 85 are provided on both sides of the outer surface of the liquid storage tanks 81. The cleaning blades 85 are slidably connected to the surface of the extruded bent plate 5. The liquid storage tanks 81 are filled with cleaning liquid, which flows through the delivery pipe 86 into the connecting pipe 84 and is sprayed onto the interior of the pipe through the spray pipe 87. This provides an ample water source during cleaning and facilitates the removal of dust from the pipe.

[0041] A slot 83 is provided on the surface of the liquid storage box 81, a delivery pipe 86 is fixedly connected to the surface of the slot 83, a connecting pipe 84 is fixedly connected to the inner surface of the delivery pipe 86, a spray pipe 87 is fixedly connected to the surface of the connecting pipe 84, and an inner push frame 82 is fixedly connected to the outer surface of the slot 83.

[0042] The inner push frame 82 includes a fixed plate 823, a push rod 822 fixedly connected to the middle of the outer surface of the fixed plate 823, and a second clamping plate 821 slidably connected to the surface of the push rod 822. The second clamping plate 821 is adapted to the first clamping plate 733. The second clamping plate 821 is slidably connected to the surface of the push rod 822. When the second clamping plate 821 and the first clamping plate 733 are in contact and squeezed, the second clamping plate 821 and the first clamping plate 733 squeeze and drive the push rod 822 to slide on the surface of the fixed plate 823. The sliding stops when it slides to the surface of the limit ring 824. When cleaning pipe fittings, the size can be adjusted according to the pipe diameter to clean pipe fittings of different models.

[0043] A limiting ring 824 is fixedly connected to the side of the outer surface of the fixing plate 823 . Four limiting rings 824 are provided, and the four limiting rings 824 are symmetrical with the push rod 822 as the center.

[0044] During use, the staff uses a clamp to clamp and fix the wire mesh skeleton pipe, and then passes the cleaning device into the inside of the wire mesh skeleton pipe. When the cleaning device is placed inside the pipe, the cleaning component 8 is affected by the shape of the pipe and is squeezed with the inner wall of the pipe. The cleaning components 8 on both sides gather toward the rotating bead 72, and make the cleaning scraper 85 slide on the surface of the extrusion bent plate 5, and squeeze the extrusion bent plate 5 when gathering toward the middle, so that the bending angle of the extrusion bent plate 5 changes, which makes it easier for the cleaning scraper 85 to fit the inner wall of the pipe. Then the staff starts the motor 1, so that the motor 1 drives the extension rod 3 to rotate and drives the deformed cleaning component 8 to rotate in the pipe to clean the pipe.

[0045] The connecting rotating ball 45 drives the rotating ball 72 on the surface of the fitting frame 6 to rotate, so that the rotating ball 72 drives the connected inner pushing frame 82 and the side clamping frame 73 to rotate, thereby cleaning the pipe wall from multiple aspects.

[0046] When encountering impurities that are difficult to clean during cleaning, the cleaning scraper 85 will fluctuate. Since the connecting rotating ball 45 is in contact with the fixed block 41, the top block 42 is pushed to slide on the surface of the pushing frame 43, so that the pushing shaft 432 pushes the ring 431 to slide on the surface of the connecting ring 434, squeezing the flip shaft 44 and causing the flip shaft 44 to flip. At this time, the pushing shaft 432 extends toward the connecting rotating ball 45 to push the rotating ball 72, thereby increasing the cleaning force on the pipe wall.

[0047] The top support frame 71 and the anti-damage support 74 are respectively arranged at the two ends of the rotating bead 72. When the cleaning device is placed inside the pipe, due to the different models and thicknesses of the pipe, the inner wall of the pipe squeezes the top support frame 71, the anti-damage support 74 and the cleaning component 8, so that the top support frame 71, the anti-damage support 74 and the cleaning component 8 fit against the inner wall of the pipe. Since the surface of the extension rod 3 is provided with a friction pusher 4, the extension rod 3 drives the friction pusher 4 to rotate. Since the sleeve plate 2 is connected to the fitting frame 6, the rotating bead 72 and the friction pusher 4 are simultaneously driven by the extension rod 3 to rotate inside the pipe to clean the pipe wall.

[0048] The spring seat 711 is made of elastic material. When the cleaning device is placed in the pipe, the friction plate 714 is squeezed by the pipe wall to squeeze the spring seat 711. The connecting seat 712 is slidably connected to the surface of the slide rod 75. The friction plate 714 fits the surface of the pipe and can be supported on the inner wall of the pipe when cleaning the pipe, thereby improving the stability of the cleaning scraper 85 when rotating during cleaning.

[0049] When the cleaning components 8 on both sides are squeezed by the pipe wall and gathered towards the middle, the inner push frames 82 on both sides are displaced towards the middle, causing the inner push frames 82 and the side clamping frames 73 to be squeezed, and the first clamping plate 733 and the second clamping plate 821 are displaced by the influence of the pipe wall. Since the first clamping plate 733 and the second clamping plate 821 are arranged opposite to each other, and the second clamping plate 821 and the first clamping plate 733 are arranged crosswise, the side clamping frames 73 limit the inner push frames 82 and fix the extrusion bent plate 5 when cleaning the pipe wall to avoid the position of the extrusion bent plate 5 from loosening during cleaning, causing jamming during cleaning.

[0050] The shell 742 is connected to the surface of the pressure rod 76, and the elastic rod 745 is supported on the inner wall of the pipe. The elastic rod 745 is made of flexible material. When the elastic rod 745 is squeezed with the inner wall, it shrinks, causing the side support flap 744 to contact the pipe wall and rotate on the surface of the base 741 under the influence of the shape, and flip upward to support the anti-damage support 74 on the surface of the pipe wall, avoiding poor fixing effect of the extrusion bend 5 during cleaning, collision with the pipe, and damage to the pipe.

[0051] The liquid storage box 81 is filled with cleaning liquid, which flows into the connecting pipe 84 along the delivery pipe 86 and is sprayed on the inside of the pipe along the spray pipe 87, providing sufficient water source during cleaning to facilitate cleaning of dust inside the pipe.

[0052] The second clamping plate 821 is slidably connected to the surface of the push rod 822. When the second clamping plate 821 is in contact with the first clamping plate 733 and squeezed, the second clamping plate 821 and the first clamping plate 733 squeeze and drive the push rod 822 to slide on the surface of the fixed plate 823.
