[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] As shown in the accompanying drawings Figures 1-3 The bent anti-fouling sewage pipeline, including first water pipe 1, first water pipe 1 one end fixedly connected with elbow 2, elbow 2 one end fixedly connected with second water pipe 3, and elbow 2 inside is provided with cleaning mechanism, and the cleaning mechanism inside is provided with water spraying assembly;

[0025] The cleaning mechanism includes rotating shell 4, and rotating shell 4 both sides are fixedly connected with rotating column 5, and rotating column 5 one end is rotatably connected with elbow 2, and rotating shell 4 surface is fixedly connected with multiple scrapers 6.

[0026] ​Specifically, in this structure, when the water flow impacts the scraper 6, the scraper 6 drives the rotating shell 4 and the rotating column 5 to rotate inside the bend 2, thereby scraping and cleaning the inside of the bend 2. During the scraping and cleaning, the water spray component flushes the scraper 6 and the inside of the pipe body, promptly washing away the blockage scraped off by the scraper 6, and reaching into the gaps and corners that the scraper 6 cannot reach, dispersing fine particles and sticky substances. When the water flow is too small to drive the scraper 6 to rotate, another water source flows into the rotating shell 4 through the water inlet pipe 8 and sprays it out at high pressure from the nozzle 7 to clean the impurities accumulated at the bottom of the bend 2. The removed impurities flow along the water flow from the second water pipe 3 into the subsequent pipe.

[0027] In a specific embodiment, as shown in the appendix Figure 2 , 3 As shown in Figures 4 and 5, the water spray assembly includes multiple nozzles 7 fixedly connected to the surface of the rotating housing 4. A water inlet pipe 8 is installed on one side of the rotating housing 4, and a one-way valve 9 is fixedly installed on one side of the water inlet pipe 8. This allows another water source to flow into the rotating housing 4 through the water inlet pipe 8 and spray out from the nozzles 7 under high pressure when the water flow into the bend 2 is too small and causes blockage. This cleans the impurities accumulated at the bottom of the bend 2. When the water flow into the bend 2 is large, the water flow drives the cleaning mechanism to rotate, which promptly washes away the blockage scraped off by the scraper 6 and reaches into the gaps and corners that the scraper 6 cannot reach, dispersing fine particles and sticky substances.

[0028] Specifically, in this structure, water flows into the rotating shell 4 through the inlet pipe 8, and is finally sprayed out through the nozzle 7 to flush the scraper 6 and the inside of the pipe body, promptly washing away the silt scraped off by the scraper 6, and penetrating into the gaps and corners that the scraper 6 cannot reach, dispersing fine particles and sticky substances.

[0029] In a specific embodiment, as shown in the appendix Figure 4 , 5 As shown, one of the rotating columns 5 has a water inlet groove 10 inside, which is fixedly connected to the rotating shell 4 so that the rotating column 5 does not affect the water inlet pipe 8 when it rotates.

[0030] Specifically, in this structure, the water inlet tank 10 is fixedly connected to the rotating shell 4.

[0031] In a specific embodiment, as shown in the appendix Figure 2 , 3 As shown in Figure 4, one end of the water inlet pipe 8 passes through the bend pipe 2, and the other end of the water inlet pipe 8 is rotatably connected to the water inlet tank 10. The nozzles 7 are arranged in a ring array around the rotating shell 4 to achieve better water spraying and prevent blockage inside the bend pipe 2.

[0032] Specifically, in the structure, the water inlet pipe 8 does not rotate when the rotating column 5 rotates, and the spray head 7 is arranged in an annular array around the rotating shell 4 to flush the inside of the elbow pipe 2.

[0033] In specific embodiments, as shown in the accompanying drawings, the scraper 6 is arranged in an arc shape, and the scraper 6 is arranged in an annular array around the rotating shell 4, so that the scraper 6 is more fitted to the elbow pipe 2 and can clean the elbow pipe 2 in a larger range. Figure 3

[0034] Specifically, in the structure, the scraper 6 is arranged in an arc shape to clean the inside of the elbow pipe 2, which is more fitted to the inside of the elbow pipe 2 during use and can clean the elbow pipe 2 in a larger range.

[0035] In specific embodiments, as shown in the accompanying drawings, the first water pipe 1 is internally inclinedly provided with a flow guide plate 11, and the flow guide plate 11 is arranged in an arc shape to guide the water flow in the first water pipe 1 and make the water flow better impact the scraper 6, so that the cleaning mechanism rotates and better scrapes the blockage. Figure 3

[0036] Specifically, in the structure, the flow guide plate 11 is internally inclinedly arranged in the first water pipe 1 to guide the water flow to the scraper 6 on one side of the rotating shell 4, so that the water flow better impacts the scraper 6, and the cleaning mechanism better cleans the inside of the pipe.

[0037] The utility model works as follows: the device is limited in the vertically placed pipe, when the water flow is small, the water flow enters the elbow pipe 2 from the first water pipe 1, when entering the elbow pipe 2, the water flow flows out from the gap on both sides of the rotating shell 4, and finally enters the subsequent pipe through the second water pipe 3, when the water flow is large, the water flow falls on the flow guide plate 11 through the first water pipe 1, the flow guide plate 11 guides the water flow in the first water pipe 1, so that the water flow falls on the scraper 6 on one side of the rotating shell 4 when passing through the elbow pipe 2, the scraper 6 drives the rotating shell 4 and the rotating column 5 to rotate, and when the scraper 6 rotates, it plays a role of guiding and scraping and cleaning the inside of the elbow pipe 2, and the water flow finally enters the subsequent pipe through the second water pipe 3.

[0038] When the blockage occurs, the water flow is generally small, and the water flow cannot drive the scraper 6 to rotate, the water inlet pipe 8 is connected to a water source, when the blockage occurs, the water source drives a water flow to enter the rotating shell 4 through the water inlet pipe 8, and finally the water flow is sprayed out through the spray head 7 to clean the impurities accumulated in the inside of the elbow pipe 2, the sludge cleaned is discharged from the second water pipe 3 to ensure the smoothness of the inside of the elbow pipe, and the one-way valve 9 prevents sewage from entering the water inlet pipe 8 to ensure the cleanliness of the inside of the water inlet pipe 8.

[0039] ​​The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
