DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1 As shown, a cleaning device for water conservancy machinery includes a moving seat 1, a lifting assembly 2 is arranged on the upper end of the moving seat 1, which can lift part of the device and push it into the inside of the pipeline, a flushing assembly 3 is arranged on the left side of the lifting assembly 2, and the flushing assembly 3 can quickly and effectively remove dirt and sediment on the inner wall of the pipeline, a rotating assembly 4 is arranged on the right side of the lifting assembly 2, which drives the cleaning assembly 5 to rotate in all directions, ensuring comprehensive coverage and cleaning of the inner wall of the pipeline, a cleaning assembly 5 is arranged on the right side of the rotating assembly 4, and a scraping assembly 6 is arranged on the right side of the cleaning assembly 5. During the rotation and movement of the scraping assembly 6, the centrifugal force is used to enhance the scraping effect on the inner wall of the pipeline to ensure thorough cleaning of the inner wall of the pipeline.

[0020] During the operation of this embodiment, through the cooperation of the lifting component 2, the flushing component 3, the rotating component 4, the cleaning component 5 and other structures, each structure rotates on the basis of revolution, driving the flushing component 3 and the cleaning component 5 to comprehensively clean the inner wall of the pipe, and always maintain the cleanliness of the brush, thereby avoiding the cleaning blind spot as a whole. At the same time, during the rotation and movement of the scraping component 6, the centrifugal force is used to enhance the scraping effect, and the inner wall is thoroughly cleaned, thereby achieving efficient, comprehensive and thorough cleaning of the inner wall of the pipe.

[0021] Embodiment 2: Based on Embodiment 1, this embodiment aims to achieve the effect of always maintaining the cleanliness of the brush while fully cleaning the inner wall of the pipeline.

[0022] For details, see Figure 1-9 The lifting component 2 includes a hydraulic device 21 fixedly connected to the upper end of the moving seat 1, and the output end of the hydraulic device 21 is fixedly connected to the fixed shell 22. The hydraulic device 21 can drive the fixed shell 22 to lift up as a whole, so that the flushing component 3 and the rotating component 4 are slightly lifted up as a whole, which is convenient for the rotating component 4 to move into the interior of the pipeline. The flushing component 3 includes a limiting seat 31 fixedly connected to the upper end of the moving seat 1, and the internal sliding connection of the limiting seat 31 is connected to the sliding seat 32. The upper end of the sliding seat 32 is fixedly connected to the water tank 33. The limiting seat 31 and the sliding seat 32 can limit the water tank 33 so that the water tank 33 can be lifted and lowered stably. The right surface of the water tank 33 is rotatably connected to a rotating hollow tube 34, which penetrates the fixed shell 22, the limiting seat 241 and the inner surface of the gear 343. The outer surface of the rotating hollow tube 34 is rotatably connected to the fixed shell 22, and the left surface of the fixed shell 22 is fixedly connected to the water tank 33.

[0023] For further information, see Figure 3 and Figure 4 A motor 341 is fixedly installed on the right surface of the water tank 33, and a gear 1 342 is fixedly connected to the output end of the motor 341, and a gear 2 343 is meshedly connected to the outer surface of the gear 1 342. The gear 1 342 can drive the gear 2 343 to rotate, and the inner surface of the gear 2 343 is fixedly connected to the outer surface of the rotating hollow tube 34, so that the rotating hollow tube 34 rotates with the gear 2 343. The upper and lower sides of the right end of the rotating hollow tube 34 are fixedly connected with connecting pipes 35, and one end of the two connecting pipes 35 is fixedly connected to a water box 36. The outer surfaces of the two water boxes 36 are provided with high-pressure nozzles 37, which can flush the inner wall of the pipe. A water pump is provided inside the water tank 33, and a water pipe 38 is fixedly connected to the output end of the water pump. The outer surface of the water pipe 38 runs through the interior of the rotating hollow tube 34 and the connecting pipe 35 and is fixedly connected to the two water boxes 36.

[0024] The water pump is located inside the water tank 33 and is a prior art. Its working principle is divided into four stages: the starting stage: at startup, the impeller starts to rotate. At this time, if the pump casing is full of liquid, the centrifugal force generated by the rotation of the impeller will throw the liquid from the center of the impeller to the surroundings, forming an initial flow of the liquid.

[0025] Suction stage: As the impeller continues to rotate, the liquid in the pump casing is continuously thrown out, forming a low-pressure area in the center of the pump casing. This low-pressure area is connected to the suction pipe, so under the action of atmospheric pressure, the liquid is sucked into the pump casing.

[0026] Pressurization stage: The sucked liquid gains energy under the action of the impeller and is continuously thrown toward the outlet of the pump casing as the impeller rotates. In this process, the speed of the liquid increases and the pressure also increases accordingly.

[0027] Liquid discharge stage: When the liquid reaches the outlet of the pump housing, its velocity and pressure reach a relatively high level. At this time, the liquid is transported to the water box 36 and the high-pressure nozzle 37 through the water pipe 38 and sprayed out.

[0028] For further information, see Figure 5-9 The rotating component 4 includes a limit seat 21 fixedly connected to the right surface of the fixed shell 22, and a limit groove 411 is provided on the right surface of the limit seat 21. The limit groove 411 can limit the gear 44 so that it remains stable when it revolves around the gear 3 43. A moving seat 22 is provided on the lower surface of the limit seat 41 to facilitate the movement of the rotating component 4 to the inside of the pipeline. The right surface of the limit seat 21 is fixedly connected to the gear 3 43, and both sides of the gear 3 43 are meshed with the gear 44. The left surfaces of the two gears 44 are fixedly connected with the rotating shaft 1 45, and the outer surfaces of the two rotating shafts 1 45 are rotatably connected to the limit groove 411. The two gears 44 will mesh with the gear 3 43 while revolving around the gear 3 43, so that the two gears 44 rotate.

[0029] Furthermore, the right end of the rotating shaft 1 45 is fixedly connected to a rotating seat 1 46, and the rotating seat 1 46 rotates together with the rotating shaft 1 45 and the gear 4 44. The outer surface of the rotating hollow tube 34 is fixedly connected to the rotating seat 2 47. When the rotating hollow tube 34 rotates, it drives the rotating seat 2 47 to rotate, thereby driving the two gears 44 to revolve around the gear 3 43 as the axis. The front and rear sides of the rotating seat 2 47 are provided with a through groove 1 471, and the inner surface of the through groove 1 471 is rotatably connected to the rotating shaft 1 45. The rotating shaft 1 45 passes through the through groove 1 471. It is connected to the rotating seat 1 46, and both sides of the right surface of the rotating seat 2 47 are fixedly connected with fixed shafts 48. The right surfaces of the two fixed shafts 48 are fixedly connected with gears 5 49. The right surface of the gear 5 49 is in contact with the rotating seat 1 46. The rotating shaft 1 45 penetrates the fixed shaft 48 and the inner surface of the gear 5 49 and is connected to the rotating seat 1 46. The front and rear sides of the two gears 5 49 are respectively meshed with two gears 6 410. The two gears 6 410 revolve around the gear 5 49 as the axis. During the revolution, the two gears mesh so that the two gears 6 410 rotate.

[0030] For further information, see Figure 7 and Figure 8The cleaning assembly 5 includes a rotating shaft 2 51 fixedly connected to the gear 6 410 on the front side of the gear 5 49. The rotating shaft 2 51 passes through the inner surface of the rotating seat 1 46 and is rotatably connected to the rotating seat 1 46. A cleaning brush 52 is provided on the outer surface of the rotating shaft 2 51 for cleaning the inner wall of the pipe. A scraper 1 53 is fixedly connected to the front side of the right surface of the rotating seat 1 46. The outer surface of the cleaning brush 52 is movably connected to the scraper 1 53. The scraper 1 53 revolves with the rotating seat 1 46, and the cleaning brush 52 rotates while revolving with the rotating seat 1 46. At this time, the cleaning brush 52 will continuously interact with the scraper 1 53. Friction causes scraper 1 53 to scrape off the mud and sand on the surface of the cleaning brush 52, so that the cleaning brush 52 is always kept clean. The right surface of gear 6 410 located on the rear side of gear 5 49 is fixedly connected with rotating shaft 3 54. The cleaning brush 52 and scraper 2 55 both follow rotating seat 2 47 for a large revolution and follow rotating seat 1 46 for a small revolution, and both are also rotating on their own. The length of rotating shaft 2 51 and rotating shaft 3 54 is flush with the other end of the pipeline, so that the inner wall of the entire pipeline can be cleaned. The outer surface of rotating shaft 3 54 is fixedly connected with scraper 2 55, which can scrape off the mud and sand adhered to the inner wall of the pipeline.

[0031] Push the device as a whole to the mouth of the pipe, start the hydraulic device 21 to lift the fixed shell 22, the flushing component 3 and the rotating component 4 upwards, so that the movable seat 2 42 leaves the ground. At this time, push the movable seat 1 as a whole to move forward, so that the movable seat 2 42 moves to the inside of the pipe, and then start the water pump inside the water tank 33 to allow the water to be transported to the high-pressure nozzle 37 through the water pipe 38 and sprayed out. At this time, push the movable seat 1 to drive the device to move inward, so that it can evenly flush the inner wall of the pipe. When the high-pressure nozzle 37 has completely flushed the entire section of the pipe, manually pull the movable seat 1 backward and start the motor 341.

[0032] The motor 341 drives the gear 1 342 and the gear 2 343 to rotate, so that the rotating hollow tube 34 rotates, and the rotating hollow tube 34 drives the high-pressure nozzle 37 to rotate. The rotation of the high-pressure nozzle 37 drives the two gears 4 44 to revolve around the gear 3 43 as the axis. During the revolution, the gear 4 44 meshes with the gear 3 43, so that the two gears 4 44 rotate while revolving. The rotation of the gear 4 44 drives the rotating shaft 1 45 and the rotating seat 1 46 to rotate. The rotation of the rotating seat 1 46 drives the two gears 6 410 to revolve around the gear 5 49 as the axis. During the revolution, the gear 5 49 meshes with the gear 6 410. The two gears 6 410 rotate, driving the cleaning brush 52 and the scraper 2 55 to revolve around the rotating seat 2 47 as a whole. It also follows the gear four 44, the rotating shaft one 45 and the rotating seat one 46 to make a small revolution, and at the same time, the cleaning brush 52 and the scraper two 55 themselves rotate, so as to comprehensively clean and scrape the inner wall of the flushed pipe. Moreover, when the scraper one 53 follows the rotating seat one 46 to make a revolution, the cleaning brush 52 follows the rotating seat one 46 to rotate while revolving. At this time, the cleaning brush 52 will continuously rub against the scraper one 53, so that the scraper one 53 will scrape off the mud and sand on the surface of the cleaning brush 52, so as to always keep the cleaning brush 52 clean. At the same time, during the retreat, the rotating hollow tube 34 will also drive the connecting tube 35, the water box 36 and the high-pressure nozzle 37 to rotate as a whole, so that they rotate while retreating and perform a secondary flushing on the inner wall of the pipe, thereby ensuring the cleaning efficiency of the pipe.

[0033] Therefore, through the cooperation between the rotating component 4 and the cleaning component 5, the cleaning component 5 can be rotated in all directions to ensure the comprehensive coverage and cleaning of the inner wall of the pipe, and the cleaning brush 52 can complete self-cleaning while cleaning the inner wall of the pipe, so that the cleaning brush 52 always remains clean, ensuring the cleaning effect of the inner wall of the pipe.

[0034] Embodiment 3: Based on Embodiments 1 and 2, this embodiment aims to achieve the effect of scraping away all the residual sand inside the pipeline after cleaning the inner wall of the pipeline.

[0035] For details, see Figure 1 and Fig.10 The scraping assembly 6 includes a connecting rod 61, the left end of which is fixedly connected to the right end of the rotating hollow tube 34, the outer surface of the connecting rod 61 is fixedly connected to a connecting rod 2 62, and the front and rear ends of the connecting rod 2 62 are fixedly connected to fixing rings 63.

[0036] For further information, see Fig.10, the opposite sides of the two fixed rings 63 are fixedly connected with a plurality of telescopic rods 64, and the ends of the telescopic rods 64 away from the fixed rings 63 are commonly fixedly connected with a scraper ring 65, and the adjacent sides of the two scraper rings 65 are fixedly connected with a plurality of springs 66. When the connecting rod 61 rotates at a high speed, the scraper ring 65 will open to both sides due to the centrifugal force of the spring 66, thereby contacting the inner wall of the pipe. The plurality of springs 66 are all sleeved on the outer surfaces of the plurality of telescopic rods 64. The telescopic rods 64 can limit the springs 66, so that it can be stably extended and retracted without shaking left and right.

[0037] When the device is pushed backward as a whole, the rotating hollow tube 34 is in a rotating state. During the retreat, the other devices clean the inner wall of the pipe while performing secondary flushing. The scraper assembly 6 is located at the rear side of the device. When the rotating hollow tube 34 rotates, the spring 66 will rotate so that the centrifugal force drives the scraper rings 65 on both sides to open, so that they contact the inner wall of the pipe, so that the scraper rings 65 rotate and retreat at the same time, and all the sewage and mud flushed and swept are scraped away.

[0038] Therefore, this solution cooperates with the flushing component 3 and the scraping component 6 so that when the device retreats, it can scrape out all the sewage and mud remaining on the inner wall of the pipeline from the previous cleaning, effectively scrape off the stubborn dirt and residue attached to the inner wall, and ensure that the inner wall of the pipeline is thoroughly cleaned.

[0039] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic device 21, motor 341 and high-pressure nozzle 37 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
