DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0027] There are many types of foreign objects inside the pipeline. Some foreign objects in the pipeline can be cleaned by water pressure or air pressure, such as some paper towels or other foreign objects that are easy to clean; some foreign objects in the pipeline can be cleaned by existing pipeline cleaning devices, such as sludge in the pipeline, which can be scraped off the sludge deposited on the inner wall of the pipeline by the scraper of the existing pipeline cleaning device; however, foreign objects in the pipeline do not only include paper towels, sludge or other foreign objects that are easy to clean, but there may also be foreign objects such as plastic bags, bones, stones or ropes. These foreign objects have been soaked in the pipeline for a long time, such as rope-like foreign objects, and some of them have been corroded. The uncorroded parts have formed floc-like and tough foreign objects. These foreign objects are difficult to clean by water pressure or air pressure, and are also difficult to scrape off by the scraper of the existing pipeline cleaning device. Based on the above problems, this embodiment provides a pipeline cleaning device to clean foreign objects in the pipeline that are difficult to clean by existing methods or devices.

[0028] like Figure 1-5 As shown, this embodiment provides a pipeline cleaning device, comprising:

[0029] The base 1 can be a flat plate or a cubic block. Both the flat plate and the cubic block can be made of wood, aluminum alloy, stainless steel and other materials. The function of the base 1 is to provide a reaction force to the first telescopic mechanism 2, so that the end of the first telescopic mechanism 2 connected to the base 1 remains stationary, while the movable end of the first telescopic mechanism 2 is telescoped into the pipe.

[0030] The first telescopic mechanism 2 is connected to the base 1; the first telescopic mechanism 2 can be an existing air cylinder, a hydraulic cylinder, an electric push rod (electric telescopic rod) or a screw rod assembly driven by a motor, and the screw rod of the screw rod assembly is rotated to make the connecting block threadably connected to the screw rod slide along the screw rod; the first telescopic mechanism 2 of this embodiment adopts an electric telescopic rod, the fixed end of the electric telescopic rod is fixedly connected to the base 1, and the movable end of the electric telescopic rod can extend or retract relative to the base 1.

[0031] The first driving mechanism is connected to the first telescopic mechanism 2 so as to extend and retract along with the first telescopic mechanism 2; the first driving mechanism may be a rotating motor 6, the fixed end of the rotating motor 6 is connected to the movable end of the first telescopic mechanism 2, so that when the movable end of the first telescopic mechanism 2 performs a telescopic action, the first driving mechanism can move in the pipeline along with the movable end of the first telescopic mechanism 2.

[0032] The drill bit assembly 18 is connected to the first driving mechanism so as to rotate along with the rotating end of the first driving mechanism; the drill bit assembly 18 can be an existing pointed cone drill bit or a flat-mouth drill bit. One end of the drill bit assembly 18 is connected to the rotating end of the first driving mechanism, so as to rotate along with the rotating end of the first driving mechanism, foreign matter inside the pipe can be cleaned.

[0033] The first scraper assembly 19 is arranged on the drill assembly 18 or on the rotating end of the first driving mechanism. The first scraper assembly 19 can be an existing scraper structure. By arranging the first scraper assembly 19 on the drill assembly 18 or on the rotating end of the first driving mechanism, when the drill bit crushes and destroys foreign matter in the pipeline, the first scraper assembly 19 can clean up the flocculent and tough foreign matter around the drill bit.

[0034] When in use, the base 1, the first telescopic mechanism 2, the first driving mechanism, the drill bit assembly 18 and the first scraper assembly 19 are assembled in sequence according to the above-mentioned connection method to form a pipeline cleaning device, and the drill bit assembly 18 and the first scraper assembly 19 of the pipeline cleaning device are first extended into the pipeline from the port of the pipeline, and then the first driving mechanism is started, the first driving mechanism drives the drill bit assembly 18 to rotate, and the drill bit assembly 18 drives the first scraper assembly 19 to rotate, the drill bit assembly 18 begins to destroy and crush hard foreign objects or foreign objects with high toughness (plastic bags, bones, stones or ropes) inside the pipeline, and the first scraper assembly 19 scrapes off hard foreign objects or foreign objects with high toughness (plastic bags, bones, stones or ropes) located around the drill bit assembly 18. After cleaning a part of the area, the first telescopic mechanism 2 is started, driving the first driving mechanism, the drill bit assembly 18 and the first scraper assembly 19 to extend deeper into the pipeline, and the above cleaning work is repeated until the pipeline cleaning work is completed.

[0035] like Figure 1-2 As shown, in some embodiments, the first scraper assembly 19 includes a plurality of first scrapers, and the plurality of first scrapers are evenly arranged on the drill bit assembly 18. Specifically, the number of the first scrapers is four or six, and the four or six are evenly distributed along the circumference of the drill bit of the drill bit assembly 18. During use, since the first scrapers are evenly distributed along the circumference of the drill bit assembly 18, foreign matter around the drill bit assembly 18 can be quickly cleaned.

[0036] like Figure 1-2 As shown, in some embodiments, the first scraper is hollowed out. By hollowing out the first scraper, the overall weight of the first scraper assembly 19 can be reduced, thereby reducing the energy loss of the first driving mechanism driving the drill assembly 18 and the first scraper assembly 19 to rotate.

[0037] like Figure 1-2 As shown in Figures 5 and 6, in some embodiments, the pipeline cleaning device further includes a second scraper assembly, which is connected to the first driving mechanism to rotate with the rotating end of the first driving mechanism. Considering that the first scraper assembly 19 is arranged on the drill assembly 18 to clean foreign matter around the drill assembly 18, it is not possible to effectively clean foreign matter such as silt on the inner wall of the pipeline. Therefore, the second scraper assembly is arranged on the first driving mechanism to clean foreign matter on the inner wall of the pipeline, so that the pipeline can be cleaned more thoroughly.

[0038] like Figure 1-2 As shown in Figures 5 and 6, in some embodiments, the second scraper assembly includes a connecting seat 9, a second telescopic mechanism 16, and a second scraper 17. The connecting seat 9 is connected to the rotating end of the first driving mechanism to rotate with the rotating end of the first driving mechanism. The fixed end of the second telescopic mechanism 16 is connected to the connecting seat 9, and the second scraper 17 is connected to the movable end of the second telescopic mechanism 16. The connecting seat 9 is a block, which is sleeved on the outer surface of the rotating end of the first driving mechanism. The second telescopic mechanism 16 is consistent with the first telescopic mechanism 2, and both can adopt existing cylinders, hydraulic cylinders, and electric push rods (electric telescopic rods). This embodiment adopts an electric telescopic rod. By setting the second telescopic mechanism 16, the second scraper assembly can be adjusted according to pipes of different sizes, so that the second scraper 17 can contact the inner wall of the pipe to clean the inner wall of the pipe.

[0039] like Figure 1-2 As shown, in some embodiments, there are multiple second scrapers 17 and multiple second telescopic mechanisms 16, and multiple second telescopic mechanisms 16 are evenly distributed on the connecting seat 9 in the circumferential direction, and multiple second scrapers 17 are respectively connected to the movable ends of multiple second telescopic mechanisms 16. By providing multiple second scrapers 17, the inner wall of the pipeline can be cleaned quickly, thereby improving the cleaning efficiency.

[0040] like Figure 1-5As shown, in some embodiments, the pipeline cleaning device also includes a sewage extraction mechanism 3, which includes a sewage extraction component and a sewage extraction channel 4, one end of the sewage extraction channel 4 is connected to the sewage extraction component, and the other end of the sewage extraction channel 4 is connected to the first driving mechanism; the sewage extraction component is connected to the movable end of the first telescopic mechanism 2 to extend and retract with the first telescopic mechanism 2. Specifically, the drill bit assembly 18 includes a drill bit and a rotating seat 11. The drill bit is a flat-end drill bit (cylindrical drill bit structure). The flat-end drill bit is hollow inside and has openings at both ends. The first scraper is connected to the outer end of the flat-end drill bit, and the other end of the flat-end drill bit is connected to the rotating seat 11. The rotating seat 11 is provided with a through hole of the same size as the opening of the flat-end drill bit, and the through hole corresponds to the opening of the flat-end drill bit; the first driving mechanism includes a rotating motor 6 and a limiting base 5. The limiting base 5 is connected to the sewage extraction channel 4 through the cooperation of the card slot 14 and the card block 15 structure. The rotating motor 6 is fixed in the limiting base 5. The limiting base 5 is a sleeve structure. The card slot 14 is set at one end of the limiting base 5, and the card block 15 is set at the other end of the sewage extraction channel 4. The card block 15 is embedded in the card slot 14 and rotated by a certain angle so that the card block 15 is staggered from the notch of the card slot 14, thereby achieving the cooperation between the two. A crushing piece 8 is sleeved on the rotating end 7 of the rotating motor, and the rotating end 7 of the rotating motor is connected to the connecting seat 9, and the rotating seat 11 is connected to the connecting seat 9 through the connecting shaft 10; the sewage extraction component can be an existing negative pressure pump or a related negative pressure structure.

[0041] like Figure 1-5 As shown, the principle of the sewage extraction mechanism 3 is that when the sewage extraction component is started, negative pressure is generated in the sewage extraction channel 4. Since the sewage extraction channel 4 is connected with the limiting base 5, negative pressure is also generated at the connection between the limiting base 5 and the sewage extraction channel 4. The rotating motor 6 cooperates with the operation of the crushing piece, and negative pressure adsorption is also generated in the area of ​​the drill bit assembly, the first scraper assembly and the second scraper assembly. Since the connecting seat 9 is connected to the rotating seat 11 through the connecting shaft 10, and the rotating seat 11 is connected to the flat drill bit, the rotating seat 11 and the flat drill bit also generate negative pressure, so that the foreign matter crushed by the flat drill bit can be sucked. When the foreign matter is sucked to the rotating motor 6, since the crushing piece 8 is provided on the rotating motor 6, the crushing piece 8 can further crush and adsorb the foreign matter, and then it is sucked into the sewage extraction channel 4, and finally transmitted from the sewage extraction channel 4 to the outside of the pipeline, thereby avoiding secondary blockage of the pipeline during the cleaning process.

[0042] like Figure 4As shown, in some embodiments, the sewage extraction assembly includes a second drive mechanism 13 and a fan blade, the second drive mechanism 13 is connected to the movable end of the first telescopic mechanism 2 through the support frame 12, and the fan blade is connected to the second drive mechanism 13 to rotate with the rotating end of the second drive mechanism 13. Considering that if the sewage extraction assembly uses a vacuum pump or other negative pressure structure, and the first drive mechanism uses a rotary motor 6, therefore, for convenience, both use an electric drive mode, and the second drive mechanism 13 also uses a rotary motor, so there is no need to carry an additional vacuum pump or find an air source to achieve suction.

[0043] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
