[0013] Optionally, a first ear seat and a second ear seat are slidably provided on the vertical rod, an elastic member is connected between the first ear seat and the second ear seat, one end of the first connecting rod is hinged on the first ear seat, and one end of the second connecting rod is hinged on the second ear seat.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: 1. Place the driving body in the pipe. The first reducing assembly drives the cleaning brush to move toward the inner wall of the pipe and abut against the inner wall of the pipe. The second reducing assembly drives the moving assembly to move toward the inner wall of the pipe, so that the device can be moved and cleaned in pipes with different inner diameters, thereby enhancing the adaptability of the device. At the same time, the driving motor drives the driving shaft to rotate, and the driving shaft drives the cleaning brush to make a circular motion on the inner wall of the pipe to clean the inner wall of the pipe. The cleaning brushes are arranged in a staggered manner along the length of the pipe, thereby increasing the cleaning area of ​​the cleaning brush in one rotation and improving the cleaning efficiency. The moving assembly can drive the dust removal assembly to move along the length of the pipe, so that the cleaning brush spirals forward on the inner wall of the pipe, thereby facilitating all-round cleaning of the inner wall of the pipe and reducing the possibility of omissions in the cleaning of the inner wall of the pipe; 2. When the cleaning brush spirals forward in the pipe, the water flow on the inner wall of the pipe will also spiral forward on the inner wall of the pipe due to the thrust of the cleaning brush. When the water flow spirals forward in the pipe, the water flow will preliminarily clean the inner wall of the pipe. At the same time, when the water flow is thrust by the cleaning brush, the impact of the water flow will increase, and the dust removal effect of the water flow will be enhanced. Finally, the sewage after cleaning the pipe receives the thrust of the cleaning brush and flows out from the port of the pipe, further improving the cleaning effect of the inner wall of the pipe. When the cleaning brush spirals forward on the inner wall of the pipe, it can not only enhance the cleaning effect of the inner wall of the pipe, but also push the water flow to spiral forward in the pipe, pre-clean the inner wall of the pipe, and discharge the cleaned sewage from the pipe.

[0015] 3. When the driving shaft rotates, it drives the water collecting box to rotate. The movable tube rotates on the spherical tube due to the centrifugal force, thereby changing the spraying angle of the movable tube. When the spraying tube sprays obliquely on the inner wall of the pipe, it can more effectively reach the inside of the object or the blind hole area, thereby producing a better dust removal effect in these areas; at the same time, when the water collecting box rotates, the water flow in the water collecting box is gathered on the inner wall of the water collecting box due to the centrifugal effect, and is discharged from the movable tube by the centrifugal effect. The faster the rotation speed of the water collecting box, the stronger the centrifugal effect, the greater the impact force of the water flow discharged from the movable tube, and the stronger the cleaning effect on the pipe.

[0016] 4. When the drainage box continues to drain water in the pipe, there will be too much water in the pipe, which will cause resistance to the cleaning brush, increase the energy consumption of the drive motor, and waste water resources. Therefore, after the water collection tank drains water for a period of time, it pushes the inner gear to slide on the drive shaft, so that the inner gear and the outer gear are separated. At this time, the drive shaft no longer drives the water collection tank. The water collection tank slows down its speed under the action of inertia until the water collection tank stops rotating. During this time, the drainage volume of the movable pipe will gradually decrease until it stops, thereby reducing the loss of water resources and the energy consumption of the drive motor.

[0017] 5. On the one hand, when the driving shaft rotates, it drives the sliding seat to move on the sliding guide rail, and the cleaning brush fits against the inner wall of the pipe through the centrifugal effect, which enhances the applicability of the dust removal component and facilitates the cleaning of pipes with different inner diameters. On the other hand, when the cleaning brush makes a circular motion on the inner wall of the pipe, the centrifugal force continuously provides the cleaning brush with an extrusion force toward the inner wall of the pipe, thereby increasing the friction between the cleaning brush and the inner wall of the pipe, and further enhancing the cleaning effect of the cleaning brush. On the third hand, the rotation of the driving shaft can also drive the cleaning brush to make a circular motion on the inner wall of the pipe, driving the dust removal component, reducing the number of driving sources, simplifying the structure of the present application, and reducing energy loss.

[0020] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0021] A dust removal device for producing air conditioning insulation plastics, referring to Figures 1 to 4, including a driving body 1, a moving component 2, a dust removal component 3 and a reducing component 4. The driving body 1 includes a driving motor 12, a driving shaft 13 and a protective cover 11. The driving motor 12 is installed in the protective cover 11. The driving shaft 13 is connected to the output end of the driving motor 12 and passes through the protective cover 11. The driving shaft 13 is used to drive the dust removal component 3 to remove dust from the inner wall of the pipeline.

[0022] Reference Figure 1 The dust removal assembly 3 includes a plurality of driving rods 415 and cleaning brushes 31 corresponding to the plurality of driving rods 415. The plurality of driving rods 415 are evenly distributed around the periphery of the driving shaft 13, and the driving rods 415 are parallel to the driving shaft 13. The lengths of the plurality of driving rods 415 are different. The cleaning brushes 31 are arranged obliquely with the driving rods 415. The ends of the driving rods 415 are connected to the middle of the cleaning brushes 31, so that the cleaning brushes 31 are arranged in a staggered manner along the length direction of the pipeline. The cleaning brushes 31 are arc-shaped and the side of the cleaning brushes 31 opposite to the inner wall of the pipeline is an elastic pad. The driving shaft 13 can drive the cleaning brushes 31 to fit on the inner wall of the pipeline and make a circular motion along the inner wall of the pipeline.

[0023] Reference Figure 1 The cleaning brush 31 is arranged around the driving shaft 13, and the driving rod 415 has different lengths. The cleaning brush 31 is arranged along the length direction of the pipeline, thereby increasing the dust removal area of ​​the cleaning brush 31 when it rotates in the pipeline, and improving the cleaning efficiency of the inner wall of the pipeline. The setting of the elastic pad can make the cleaning brush 31 fit more closely with the inner wall of the pipeline, increase the friction between the cleaning brush 31 and the inner wall of the pipeline, and thus facilitate the cleaning of stubborn stains attached to the inner wall of the pipeline, and improve the cleaning effect of the cleaning brush 31 on the inner wall of the pipeline.

[0024] Reference Figure 1 and Figure 2 The reducing assembly 4 includes a first reducing assembly 41 and a second reducing assembly 42. The first reducing assembly 41 includes a fixed disk 411 which is sleeved and fixed on the drive shaft 13. A plurality of sliding guide rails 412 are arranged at the bottom of the fixed disk 411. In the present embodiment, four sliding guide rails 412 are arranged and are evenly distributed on the bottom wall of the fixed disk 411. A sliding seat 413 is slidably arranged on the sliding guide rail 412. An adjusting rod 414 is connected to the sliding seat 413. An end of the adjusting rod 414 away from the sliding seat 413 is fixedly connected to the drive rod 415.

[0025] When the driving motor 12 drives the driving shaft 13 to rotate, the fixed disk 411 rotates along with the driving shaft 13. When the fixed disk 411 rotates, the sliding seat 413 moves on the sliding guide rail 412 due to the centrifugal force. Several sliding seats 413 move toward the peripheral side wall of the fixed disk 411 closest to them, until the cleaning brush 31 fits with the inner wall of the pipeline. The cleaning brush 31 fits tightly against the inner wall of the pipeline due to the centrifugal force. At the same time, when the fixed disk 411 rotates, it drives the cleaning brush 31 to make a circular motion with the driving shaft 13 as the center, so as to remove dust from the inner wall of the pipeline.

[0026] When the cleaning brush 31 performs a circular motion on the inner wall of the pipe, the centrifugal force continuously provides an extrusion force on the cleaning brush 31 toward the inner wall of the pipe, thereby increasing the friction between the cleaning brush 31 and the inner wall of the pipe, thereby enhancing the cleaning effect of the cleaning brush 31 .

[0027] On the one hand, when the drive shaft 13 rotates, the sliding seat 413 is driven to move on the sliding guide rail 412, and the cleaning brush 31 is made to fit the inner wall of the pipe through the centrifugal effect, thereby enhancing the applicability of the dust removal component 3 and facilitating the cleaning of pipes with different inner diameters. On the other hand, the centrifugal effect generated by the drive shaft 13 can enhance the friction between the cleaning brush 31 and the inner wall of the pipe. When the cleaning brush 31 rotates on the inner wall of the pipe, the cleaning effect on the inner wall of the pipe can be improved. On the third hand, the rotation of the drive shaft 13 can also drive the cleaning brush 31 to make a circular motion on the inner wall of the pipe, driving the dust removal component 3, reducing the number of driving sources 23, simplifying the structure of the present application, and reducing energy loss.

[0028] Reference Figure 1 and Figure 2 The dust removal assembly 3 includes a spray unit for spraying water on the inner wall of the pipeline. The spray unit includes a water collecting box 32 and a plurality of sprayers 33 arranged on the side wall of the water collecting box 32. The water collecting box 32 is sleeved on the driving shaft 13 and can rotate coaxially with the driving shaft 13. The sprayer 33 includes a spherical tube 331 and a movable tube 332 that are connected to each other. One end of the spherical tube 331 is connected to the side wall of the water collecting box 32, and one end of the movable tube 332 is sleeved on the spherical tube 331 and can rotate on the spherical tube 331.

[0029] When the driving motor 12 drives the driving shaft 13 to rotate, the water collecting box 32 rotates together with the driving shaft 13 in the pipeline, and the movable tube 332 is affected by the centrifugal force, and the movable tube 332 can swing on the spherical tube 331, so that the opening direction of the movable tube 332 changes, so that the movable tube 332 performs oblique spraying to remove dust on the inner wall of the pipeline. Compared with direct spraying, oblique spraying can more effectively reach the inside of an object or the blind hole area, thereby producing a better dust removal effect in these areas. At the same time, when the water collecting box 32 rotates, the water flow in the water collecting box 32 is gathered on the inner wall of the water collecting box 32 by the centrifugal effect, and is discharged from the movable tube 332 by the centrifugal effect. When the rotation speed of the water collecting box 32 is faster, the centrifugal effect is stronger, the impact force of the water flow discharged from the movable tube 332 is greater, and the cleaning effect on the inside of the pipe is stronger.

[0030] Reference Figure 2 and Figure 4 , an inner gear 34 is fixedly connected to the water collecting tank 32, an outer gear 35 meshing with the inner gear 34 is slidably provided on the drive shaft 13, a baffle (not shown in the figure) is fixedly connected to the side of the inner gear 34 close to the water collecting tank 32, and the baffle plays a blocking role on the inner gear 34, reducing the inner gear 34 from being separated from the outer gear 35 close to the baffle. A sliding groove 36 is provided on the outer wall of the drive shaft 13, and the sliding groove 36 is arranged along the length direction of the drive shaft 13. A limit block 37 inserted into the sliding groove 36 is fixedly connected to the inner ring wall of the outer gear 35, and the limit block 37 can slide in the sliding groove 36. An electric push rod 38 is provided on the driving body 1, and the driving end of the electric push rod 38 can push the outer gear 35 to slide on the drive shaft 13, so that the outer gear 35 is separated from the inner gear 34.

[0031] The cooperation of the stop block 37 and the sliding groove 36 enables the outer gear 35 to rotate coaxially with the drive shaft 13, and the outer gear 35 can slide in the length direction of the drive shaft 13. When the drainage box continues to drain water in the pipeline, it will cause too much water in the pipeline, resulting in a waste of water resources. At the same time, too much water flow in the pipeline will produce resistance to the rotation of the cleaning brush 31 and the forward movement of the moving component 2, increasing the energy loss of the driving device. Therefore, after the water collecting tank 32 drains water for a period of time, the electric push rod 38 is controlled to push the inner gear 34 to slide on the drive shaft 13, so that the inner gear 34 is separated from the outer gear 35. At this time, the drive shaft 13 no longer drives the water collecting tank 32, and the rotation speed of the water collecting tank 32 gradually slows down until the water collecting tank 32 stops rotating. During this time, the drainage volume of the movable tube 332 will gradually decrease until it stops, thereby reducing the loss of water resources and the energy consumption of the drive motor 12.

[0032] Reference Figure 1 and Figure 2A vertical rod 14 is fixedly arranged in the protective cover 11, and the second diameter reducing assembly 42 includes a plurality of cross-linking rod groups arranged between the vertical rod 14 and the moving assembly 2, and the cross-linking rod group includes a first link 421 and a second link 422 arranged crosswise with each other, and the middle parts of the first link 421 and the second link 422 are hinged to each other, and a first ear seat 423 and a second ear seat 424 are sleeved and slidably arranged on the vertical rod 14, and an elastic member 425 is connected between the first ear seat 423 and the second ear seat 424, and the elastic member 425 is a spring, and the elastic member 425 is in a compressed state. One end of the first link 421 is hinged on the first ear seat 423, and the other end of the first link 421 is hinged on the moving assembly 2, one end of the second link 422 is hinged on the second ear seat 424, and the other end of the second link 422 is hinged on the moving assembly 2. A positioning rod is connected between the first ear seat 423 and the second ear seat 424 , and the positioning rod is used to limit the relative rotation between the first ear seat 423 and the second ear seat 424 .

[0033] The first ear seat 423 and the second ear seat 424 are moved on the vertical rod 14 and away from each other, so that the elastic member 425 is stretched and the moving component 2 moves toward the direction close to the vertical rod 14. Then the moving component 2 is placed in the pipe, and the elastic member 425 shrinks and deforms, so that the first ear seat 423 and the second ear seat 424 are close to each other, and the moving component 2 is driven to move in the direction away from the vertical rod 14, so that the moving component 2 abuts against the inner wall of the pipe, thereby facilitating the movement of the moving component 2 on the inner wall of the pipe.

[0034] Reference Figure 2 and Figure 3 The moving assembly 2 includes a housing 21 and a crawler 22 arranged around the housing 21. An articulated seat is arranged on the outer wall of the housing 21. The ends of the first connecting rod 421 and the second connecting rod 422 are both hinged on the articulated seat. A driving unit for driving the crawler 22 to move is arranged in the housing 21. The driving unit includes a driving wheel 25 that is rotatably arranged in the crawler 22. The driving wheel 25 is engaged with the crawler 22. The number of the driving wheels 25 is not less than two. A driving source 23 for driving the driving wheels 25 on both sides to rotate is arranged in the housing 21. A connecting rod 24 is connected between the driving wheels 25 on both sides of the housing 21. A first bevel gear 26 is sleeved and fixedly connected on the connecting rod 24. The output end of the driving source 23 is connected to a second bevel gear 27 that meshes with the first bevel gear 26.

[0035] The driving source 23 drives the second bevel gear 27 to drive the first bevel gear 26 to rotate, thereby driving the driving wheel 25 to rotate, and the driving wheel 25 drives the track 22 to move on the inner wall of the pipeline, thereby driving the dust removal component 3 to move in the pipeline. The second variable diameter component 42 can adjust the distance between the track 22 and the vertical rod 14, so that the moving component 2 can adapt to pipelines with different inner diameters, so that the track 22 can fit on the inner wall of the pipeline and move in the pipeline, thereby driving the dust removal component 3 to perform comprehensive dust removal on the inner wall of the pipeline.

[0036] Under the action of the moving assembly 2 and the driving shaft 13, the cleaning brush 31 can spirally move forward in the pipe, and the water flow on the inner wall of the pipe will also spirally move forward on the inner wall of the pipe under the thrust of the cleaning brush 31. When the water flow spirals forward in the pipe, the water flow will preliminarily clean the inner wall of the pipe. At the same time, when the water flow is thrusted by the cleaning brush 31, the impact of the water flow will be increased, and the dust removal effect of the water flow will be enhanced. Finally, the sewage after the pipe is cleaned can flow out from the opening of the pipe, reducing the possibility of sewage remaining in the pipe and improving the cleaning effect in the pipe.

[0037] The implementation principle of a dust removal device for producing air-conditioning insulation plastic in an embodiment of the present application is as follows: a pulling force is applied to the first ear seat 423 and the second ear seat 424, so that the first ear seat 423 and the second ear seat 424 move away from each other, the elastic member 425 is stretched together, and the track 22 moves toward the direction close to the vertical rod 14, so that the dust removal device can enter the pipe with a smaller inner diameter.

[0038] Then put the dust removal device into the pipeline, remove the force on the first ear seat 423 and the second ear seat 424, and the elastic member 425 will elastically contract, so that the first ear seat 423 and the second ear seat 424 are close to each other, and the track 22 moves in the direction away from the vertical rod 14 until the track 22 is attached to the inner wall of the pipeline.

[0039] First, start the drive motor 12 to drive the drive shaft 13 to rotate. When the drive shaft 13 rotates, it drives the water collecting box 32 to rotate. The spray pipe rotates on the spherical tube 331 due to the centrifugal force, thereby changing the angle between the spray pipe and the water collecting box 32, so that the spray pipe sprays obliquely to the inner wall of the pipe, more effectively reaching the inside of the object or the blind hole area, thereby producing a better dust removal effect in these areas.

[0040] At the same time, when the water collecting box 32 rotates, the water flow in the water collecting box 32 is gathered on the inner wall of the water collecting box 32 due to the centrifugal force. The centrifugal force drives the water flow from the spherical tube 331 into the movable tube 332, and sprays out from the opening of the movable tube 332 toward the inner wall of the pipe. The faster the driving shaft 13 rotates, the stronger the centrifugal force is, and the greater the water flow impulse at the spray port is.

[0041] When the driving shaft 13 rotates, the fixed disk 411 is also driven to rotate. The sliding seat 413 is subjected to the centrifugal force and moves on the sliding guide rail 412 in a direction away from the center of the fixed disk 411 until the cleaning brush 31 is attached to the inner wall of the pipe. When the cleaning brush 31 makes a circular motion on the inner wall of the pipe, the centrifugal force continuously provides the cleaning brush 31 with an extrusion force in the direction of the inner wall of the pipe, thereby increasing the friction between the cleaning brush 31 and the inner wall of the pipe, thereby enhancing the cleaning effect of the cleaning brush 31.

[0042] The driving source 23 is restarted to drive the driving wheel 25 to rotate, so that the crawler 22 moves on the inner wall of the pipe, and the cleaning brush 31 moves forward in a spiral on the inner wall of the pipe. Since the cleaning brush 31 and the driving rod 415 are arranged obliquely, the cleaning brush 31 pushes the water flow on the inner wall of the pipe to move forward in a spiral when it moves, and when the water flow moves forward in a spiral in the pipe, the water flow will perform preliminary cleaning on the inner wall of the pipe. At the same time, when the water flow is acted upon by the thrust of the cleaning brush 31, the impulse of the water flow will be increased, thereby enhancing the dust removal effect of the water flow.

[0043] When the dust removal device moves a certain distance in the pipeline, the electric push rod 38 is controlled to push the inner gear 34 to slide on the drive shaft 13, so that the inner gear 34 is separated from the outer gear 35. At this time, the drive shaft 13 no longer drives the water collecting tank 32, and the rotation speed of the water collecting tank 32 gradually slows down until the water collecting tank 32 stops rotating. During this time, the drainage volume of the movable pipe 332 will gradually decrease until it stops, thereby reducing the loss of water resources and the energy consumption of the drive motor 12.

[0044] Finally, after the pipeline is cleaned, the sewage flows out from the opening of the pipeline due to the thrust of the cleaning brush 31, which reduces the situation where sewage remains in the pipeline, reduces the possibility of sewage drying up on the inner wall of the pipeline, and further improves the cleaning effect in the pipeline.

[0045] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks.
