[0003] Various impurities and dirt are prone to accumulate inside pipes that have been used for a long time, such as minerals in the water, rust, sediment, etc. These impurities may affect the purity and safety of the transported substances. The inner wall of the pipe may also breed bacteria, algae and other microorganisms, causing pollution to the transported liquid or gas.

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figures 1 to 9The pipeline cleaning device for pipeline transportation equipment shown in the figure comprises a pipeline body 1 and a scraping mechanism 2, wherein the scraping mechanism 2 comprises a connecting shaft 21 and a collar 25, wherein the surface of the connecting shaft 21 is evenly provided with a first slide groove 22, one end of the connecting shaft 21 is fixedly connected with a cross support frame 23, and one side of the cross support frame 23 is provided with a second slide groove 24, wherein the collar 25 is sleeved on the surface of the connecting shaft 21, and the inner wall of the collar 25 is fixedly connected with a limiting block 211, and one end of each of the four limiting blocks 211 extends to the inside of the first slide groove 22, and the collar 25 is provided with a second slide groove 24. The outer surface of the shaft 25 is rotatably connected with connecting rods 26 all around, one end of each of the four connecting rods 26 is rotatably connected with an extension rod 27, one side of each of the four extension rods 27 is fixedly connected with a slider 28, one end of each of the four sliders 28 extends to the inside of each of the four second slide grooves 24, one end of each of the four extension rods 27 is fixedly mounted with a scraper 29, the other end of the connecting shaft 21 is fixedly mounted with a turbine blade 210, one end of the connecting shaft 21 is provided with a first pull rope 3, one side of the cross support frame 23 is provided with a second pull rope 4, and one end of the second pull rope 4 is provided with a filtering mechanism 5.

[0030] When working, in the prior art, the size of the scraping mechanism 2 is adapted to the diameter of the inner wall of the pipe body 1, and the scraping mechanism 2 can move normally inside the pipe body 1. Since the pipe body 1 is bent, the scraping mechanism 2 and the filtering mechanism 5 will not be blocked when passing through the bend of the pipe body 1. The collar 25 is sleeved on the surface of the connecting shaft 21. The length of the connecting shaft 21 is relatively short, which is adapted to the extendable length of the scraping member 29. The collar 25 is clamped in each first slide groove 22 by the limit block 211, and has the same function as the second slide groove 24 on the cross support frame 23, which is used to limit the position of the connecting rod 26, etc. The slider 28 is adapted to the size of the second slide groove 24, and the first pull rope 3 is used to scrape When the wiping mechanism 2 is pulled, the ring 25, the connecting rod 26 and the extension rod 27 are impacted by the gas or liquid, so that the extension rod 27 always keeps expanding to the surroundings, ensuring that the edge of the scraper 29 can stably contact the inner wall of the pipeline body 1, thereby ensuring the cleaning effect on the inside of the pipeline body 1. The turbine blade 210 is welded on the connecting shaft 21. When the liquid or gas passes through the inside of the pipeline body 1, the force acts on the turbine blade 210, thereby driving the scraping mechanism 2 to rotate normally. A connecting block rotates in the groove at one end of the connecting shaft 21, and one end of the first pull rope 3 is tied to this connecting block to ensure that the scraping mechanism 2 can rotate normally. The second pull rope 4 is fixedly tied between the connecting shaft 21 and the filtering mechanism 5.

[0031] As a further embodiment of the present invention, the filtering mechanism 5 includes a connecting cover 51, one end of the outer surface of the connecting cover 51 is provided with an annular silicone sheet 52, one side of the inner surface of the connecting cover 51 is provided with a groove 53, a micro motor 54 is fixedly installed inside the groove 53, one end of the output shaft of the micro motor 54 is fixedly connected to a first rotating shaft 55 through a coupling, one end of the first rotating shaft 55 away from the micro motor 54 is rotatably connected to the other side of the inner surface of the connecting cover 51, and a filter element 56 is fixedly installed in the middle of the first rotating shaft 55.

[0032] During operation, in the prior art, the size of the connecting cover 51 is adapted to the filter element 56, and the annular silicone sheet 52 is adhered to the outside of the connecting cover 51. When the filter mechanism 5 moves along the inside of the pipe body 1, the edge of the annular silicone sheet 52 contacts the inner wall of the pipe body 1, playing a certain scraping role, and scraping off the impurities previously attached to the pipe body 1. At the same time, it also prevents the impurities scraped and cleaned by the scraping mechanism 2 from directly flowing out of the gap between the filter mechanism 5 and the pipe body 1, affecting the cleanliness of the transported liquid or gas. The micro motor 54 can be powered by a power cord, and this power cord is set inside the first pull rope 3 and the second pull rope 4, and rotates 180° each time.

[0033] As a further embodiment of the present invention, the filter element 56 includes two outer shells 561 , which are assembled together, and the surfaces of the two outer shells 561 are evenly provided with first connecting holes 562 , and filter pads 563 are arranged inside the two outer shells 561 .

[0034] During operation, in the prior art, two shells 561 are assembled together and installed on the surface of the first rotating shaft 55, and multiple first connecting holes 562 are evenly opened on both sides of the shell 561. The gas or liquid enters the shell 561 through the first connecting holes 562 and is filtered by the filter pad 563. The filtered gas or liquid then flows out from the first connecting holes 562 on the other side. After the filter element 56 rotates 180°, the impurities filtered out of the gas or liquid can be knocked off the filter pad 563.

[0035] As a further implementation scheme of the present invention, a rectangular frame 6 is fixedly connected to the top of the outer surface of the pipe body 1, and a second connecting hole 7 is opened inside the rectangular frame 6 and on the surface of the pipe body 1. A servo motor 8 is fixedly installed on one side of the inner wall of the rectangular frame 6, and one end of the output shaft of the servo motor 8 is fixedly connected to a second rotating shaft 9 through a coupling, a winding roller 10 is fixedly installed on the surface of the second rotating shaft 9, and one end of the first pull rope 3 is arranged on the surface of the winding roller 10.

[0036] During operation, in the prior art, the rectangular frame 6 is welded to the outside of the pipe body 1, and the servo motor 8 is connected to the solar panel 15 through a power cord to prevent the pipe body 1 from being unable to use electricity outdoors. The servo motor 8 is started regularly and one end of the first pull rope 3 is wound around the winding roller 10.

[0037] As a further implementation scheme of the present invention, a sealing cover 11 is provided on the top of the rectangular frame 6, and the four sides of the bottom of the sealing cover 11 are fixed to the rectangular frame 6 by bolts 12, and an annular groove 13 is opened in the middle of the top of the sealing cover 11, and a support rod 14 is fixedly installed in the middle of the top of the sealing cover 11, and a solar panel 15 is rotatably installed on the top of the support rod 14, and an adjustment rod 16 is rotatably installed on one side of the bottom of the solar panel 15, and the bottom end of the adjustment rod 16 extends to the inside of the annular groove 13 and is fixed by a bolt.

[0038] During operation, in the prior art, the sealing cover 11 is installed on the rectangular frame 6. When the staff inspects the pipeline, the sealing cover 11 can be opened. A sealing gasket is arranged between the sealing cover 11 and the rectangular frame 6 to ensure the sealing and avoid leakage at the second connecting hole 7, which affects the normal transportation of liquid or gas. By rotating the bottom end of the adjusting rod 16, the inclination angle of the solar panel 15 can be adjusted so that the solar panel 15 can receive and convert sunlight to the greatest extent.

[0039] As a further implementation scheme of the present invention, a limit frame 17 is fixedly installed inside the pipe body 1, and a third connecting hole 18 is opened in the middle of one end of the limit frame 17. The first pull rope 3 is connected to the scraping mechanism 2 through the third connecting hole 18, and the limit frame 17 is triangular.

[0040] During operation, in the prior art, the limit frame 17 is welded inside the pipe body 1 and is triangular in shape. When gas or liquid passes through it, the impact force on the limit frame 17 is reduced. The third connecting hole 18 is used to limit the position of the first pull rope 3 to avoid friction between the first pull rope 3 and the second connecting hole 7, which may cause the first pull rope 3 to break.

[0041] As a further embodiment of the present invention, a ring gear 57 is fixedly mounted on one side of the outer surface of the connecting cover 51 , and a connecting ring 58 is arranged around the outer surface of the ring gear 57 , and the surface of the connecting ring 58 contacts the inner wall of the pipe body 1 .

[0042] As a further embodiment of the present invention, a first bevel gear 59 is fixedly mounted on the surface of the first rotating shaft 55, a spur gear 510 is meshed with one side of the inner ring of the ring gear 57, a third rotating shaft 511 is fixedly mounted on one side of the spur gear 510, one end of the third rotating shaft 511 passes through the connecting cover 51 and extends to the inside of the groove 53, a second bevel gear 512 is fixedly mounted on one end of the third rotating shaft 511, and the second bevel gear 512 is meshed with the first bevel gear 59.

[0043] During operation, in the prior art, the ring gear 57 is welded to the connecting cover 51, the first bevel gear 59 drives the second bevel gear 512 to rotate, thereby driving the third rotating shaft 511 and the flat gear 510 to rotate, and the flat gear 510 is meshed with the ring gear 57. The connecting ring 58 allows the filter element 56 and the pipe body 1 to rotate, so that the entangled second pull rope 4 is loosened.

[0044] Working principle of the present invention:

[0045] When the pipe body 1 is normally used to transport liquid or gas, impurities are easily gathered and adhered to the bend of the pipe body 1. The solar panel 15 supplies power to the servo motor 8. The servo motor 8 is controlled by the control device and starts regularly or periodically. After the servo motor 8 starts, the winding roller 10 is driven by the second rotating shaft 9 to reel the first pull rope 3, thereby driving the scraping mechanism 2 and the filtering mechanism 5 to move inside the pipe body 1.

[0046] When the scraping mechanism 2 moves, the water pressure or air pressure squeezes the collar 25 toward one side of the cross support frame 23, so that the extension rod 27 supports the scraping member 29 in all directions, so that the scraping member 29 can contact the inner wall of the pipe, and at the same time, the turbine blade 210 is impacted by the gas or liquid and rotates, so that the scraping member 29 can rotate to clean and scrape the inner wall of the pipe body 1, and the scraped impurities continue to flow along the flow direction of the liquid or gas to the filtering mechanism 5;

[0047] When the impurities move to the filter mechanism 5 along with the liquid or gas, they enter the shell 561 from the first connecting hole 562 and are filtered by the filter pad 563. When the interior of the pipeline body 1 is cleaned uniformly later, the micro motor 54 is started to drive the filter element 56 to rotate 180° each time, and the impurities filtered by the filter pad 563 are continuously cleaned by the liquid or gas, and flow directly with the liquid or gas. When the rolled-up second pull rope 4 passes through the bend of the pipeline body 1, the micro motor 54 can rotate multiple circles quickly. Under the action of the first bevel gear 59, the second bevel gear 512, the flat gear 510 and the ring gear 57, the filter mechanism 5 rotates in the opposite direction to the scraping mechanism 2, and the entangled second pull rope 4 is loosened, and the filter mechanism 5 can move normally inside the pipeline body 1. After the cleaning is completed, the scraping mechanism 2 and the filter mechanism 5 can move backward along the inside of the pipeline body 1 under the impact of the gas or liquid, and the first pull rope 3 is also loosened from the winding roller 10, and the bend inside the pipeline body 1 is continued to be cleaned after waiting.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
