Technical Field

[0001] The invention relates to the field of sewage treatment pipelines, in particular to a sewage treatment pipeline cleaning device. Background Art

[0002] Sewage treatment pipes are mainly used to transport sewage during the sewage treatment process. Due to the high dirt content in sewage, during the long-term transportation process, the dirt will continue to adhere to and accumulate on the inner wall of the pipe, thereby continuously reducing the inner diameter of the pipe, and then affecting the sewage transportation flow. If things go on like this, the pipe may be blocked in the long run. The operating radius of traditional pipe cleaning devices is generally not adjustable. After scraping the dirt on the inner wall of the pipe, and as the dirt on the pipe wall is scraped off, the inner diameter of the pipe continues to expand. The traditional pipe cleaning device cannot expand as the inner diameter of the pipe increases, affecting the subsequent cleaning effect. Summary of the invention

[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of simplifying the description of the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0015] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the embodiments below. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of the sewage treatment pipeline cleaning device are described in detail below: Embodiment 1: Reference Figure 1-Figure 8 The present invention provides a sewage treatment pipe cleaning device, including a central pipe 10, on the outer periphery of the central pipe 10 are arranged a plurality of scraping components 4 for cleaning the inner wall of the sewage treatment pipe as the central pipe 10 rotates, the scraping component 4 includes a fixed cylinder 42 and a plurality of scrapers 43 equidistantly arranged along the fixed cylinder 42, the fixed cylinder 42 is arranged parallel to the central pipe 10, the scrapers 43 are fixed on the outer periphery of the fixed cylinder 42, the scrapers 43 are arranged along the spiral line direction, and a power component is fixed at one end of the central pipe 10 for driving the central pipe 10 to rotate and move along the pipe through water flow.

[0016] The cleaning device provided by the present invention is placed in a sewage treatment pipe, and the power component is driven by water flow to drive the central tube 10 to rotate, so that the scraping component 4 rotates around the central tube 10, thereby being able to scrape off the dirt on the inner wall of the sewage treatment pipe. At the same time, the power component drives the scraping component 4 to move along the pipe, thereby achieving cleaning of the entire pipe.

[0017] Reference Figure 3-Figure 5 A hinged rod 41 is fixedly arranged on one side of the fixed cylinder 42 close to the central tube 10. Two diameter reducing components 2 located at both ends of the central tube 10 are arranged between the scraping component 4 and the outer periphery of the central tube 10. The diameter reducing component 2 can expand the distance between the scraping component 4 and the central tube 10. The diameter reducing component 2 includes a fixed seat 21, a telescopic support rod 24 and two rotating rods 22. The fixed seat 21 is fixed on the outer periphery of the central tube 10. One end of the two rotating rods 22 is rotatably connected to one end of the fixed seat 21, and the other end of the two rotating rods 22 is rotatably connected to the hinged rod 41. The two pairs of rotating rods 22 on the same hinged rod 41 are parallel to each other. A connecting rod 23 is fixed between the two rotating rods 22 on the fixed seat 21. A groove 26 is opened on the end surface of the fixed seat 21 on one side away from the central tube 10. A rotating seat 25 is rotatably connected in the groove 26. One end of the telescopic support rod 24 is rotatably connected to the connecting rod 23, and the other end of the telescopic support rod 24 is fixed on the rotating seat 25. The telescopic support rod 24 consists of a rod sleeve and a piston rod. The piston at the end of the piston rod slides in the rod sleeve, and the rod sleeve is in a sealed state. The piston rod extends out of the rod sleeve. A rotating ring is fixed to the other end of the piston rod, and the rotating ring is sleeved on the connecting rod 23. The telescopic support rod 24 is in an extended state in the initial state.

[0018] Through the elasticity between the piston rod and the rod sleeve in the telescopic support rod 24 , the angle between the rotating rod 22 and the fixing seat 21 can be changed, so that the plurality of fixing tubes 42 can move away from or close to the central tube 10 .

[0019] Reference Figure 1-Figure 2 The power component is a fan blade mechanism 3 that rotates through the flow of sewage in the pipe. The fan blade mechanism 3 includes a rotating cylinder 31, a fixing portion 34 and a plurality of fan blades 32. The plurality of fan blades 32 are circumferentially distributed with the rotating cylinder 31 as the axis and fixed on the outer periphery of the rotating cylinder 31. The fixing portion 34 is fixed to the end of the rotating cylinder 31. A fixing ring 35 located at the axis of the central tube 10 is fixed in the central tube 10 through a connecting rod. The fixing portion 34 is fixed in the fixing ring 35. The interior of the rotating cylinder 31 is hollow and is opened at one end away from the central tube 10.

[0020] The hollow rotating cylinder 31 can effectively reduce the weight of the rotating cylinder 31 . When water flows through the fan blades 32 , the fan blades 32 can be driven to rotate around the rotating cylinder 31 , thereby causing the rotating cylinder 31 to drive the central tube 10 to rotate.

[0021] Reference Figure 2 The end of the rotating cylinder 31 where the fixing portion 34 is fixed smoothly transitions to the fixing portion 34 to form a trumpet-shaped necking portion 33 , and the necking portion 33 is located outside the end of the central tube 10 .

[0022] The trumpet-shaped constricted portion 33 can guide the water flowing out of the central tube 10 to the fan blades 32 , thereby increasing the water flow at the fan blades 32 and further improving the power of the fan blades 32 .

[0023] When the present invention is in use, it is placed from one end of the sewage treatment pipe, the fan mechanism is first extended into the pipe, and the rotating rod 22 expands outward under the elastic force of the telescopic support rod 24, so that the scraping assembly 4 moves outward until the scraper 43 abuts against the inner wall of the pipe.

[0024] Water flows in from one end of the pipe and out from the other end. After passing through the central tube 10 and the scraping assembly 4, the water flows through the fan blade mechanism 3. The water flowing through the central tube 10 passes through the constricted portion 33 and is directed to the fan blade 32, thereby increasing the water flow rate at the fan blade 32, so that the fan blade 32 rotates around the rotating cylinder 31, thereby driving the rotating cylinder 31 to rotate, and then the central tube 10 rotates, and then drives the scraping assembly 4 to rotate around the central tube 10, so that the scraper 43 rotates around the central tube 10, thereby scraping off the dirt on the pipe wall. Due to the spirally arranged scraper 43, under the push of the water flow, the scraper 43 rotates around the central tube 10 and moves along the pipe, thereby scraping off the dirt on the entire pipe wall.

[0025] As the dirt on the pipe wall is scraped off, the thickness of the dirt gradually decreases. Through the elastic force of the telescopic support rod 24, the scraping assembly 4 expands outward as the thickness of the dirt on the pipe wall decreases, thereby ensuring that the scraping assembly 4 is always in contact with the inner wall of the pipe.

[0026] Embodiment 2: The difference from the first embodiment is that, referring to Figure 6-Figure 8 The power component is a rotating head 5 that rotates through a high-pressure jet. The rotating head 5 includes a water collecting end 51, a connecting end 53 and a water supply hose 54. The water collecting end 51 is hollow inside, and one end of the water supply hose 54 is fixed to the connecting end 53. One end of the water collecting end 51 is semi-spherical, and a connecting portion 55 is fixed to the other end of the water collecting end 51. The connecting end 53 is rotatably connected to the connecting portion 55. A plurality of injection portions 52 are fixed on the outer periphery of the water collecting end 51. The injection portions 52 are arranged along a spiral line. A water spraying cavity 56 that connects the internal cavity of the water collecting end 51 with the outside is opened in the injection portion 52. One end of the water collecting end 51 to which the connecting portion 55 is fixed is fixedly connected to the inner wall of the central tube 10. The connecting portion 55 is located in the central tube 10 and coincides with the axis of the central tube 10. The water supply hose 54 runs through the central tube 10, and the other end of the water supply hose 54 is connected to a high-pressure water pump.

[0027] When the present invention is used, the rotating head 5 of the present invention is first placed in the pipeline, and then the entire device is placed in the pipeline. After the high-pressure water pump is started, the high-pressure water flows through the water supply hose 54 and enters the water collecting end 51, and then is discharged through the water spray chamber 56. Due to the spiral water spray chamber 56, the high-pressure jet discharged from the water spray chamber 56 drives the water collecting end 51 to rotate, thereby driving the central tube 10 to rotate, and then causing the scraper 43 to rotate around the central tube 10. Due to the thrust generated by the high-pressure jet, the water collecting end 51 drives the central tube 10 to move along the pipeline, so that the scraper 43 scrapes the sludge on the inner wall of the entire pipeline, and the high-pressure jet washes the scraped sludge.

[0028] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
