[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. In the process of water conservancy construction, water utilization pipelines are connected by pipes, pipe fittings and valves to transport water. Water utilization pipelines are mainly used in water supply, drainage, agricultural irrigation and water conservancy projects.

[0003] An existing authorized publication number (CN221075722U) discloses an anti-clogging pipeline for water conservancy construction, comprising a water conservancy pipeline.

Therefore, this utility model provides a clog-resistant pipeline for water conservancy engineering construction. Utility Model Content

[0005] The purpose of this application is to provide a pipe for preventing blockage during water conservancy engineering construction, in order to solve the problem mentioned in the background art that filters are usually installed to achieve the filtration effect. As the fixed filter is used for a long time, blockage will lead to a reduction in the effective filtration area, a decrease in filtration efficiency, and an increase in pipe resistance, which will affect the flow stability of the overall system.

[0008] Preferably, an air pump is fixedly connected to the outside of the second pipe, the output end of the air pump passes through the second pipe, and the output end of the air pump is fixedly connected to the annular vent pipe.

[0009] Preferably, flanges are provided on the outer sides of the first pipe and the second pipe, and a second spiral guide groove is provided on the inner side of the first pipe.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, the centrifugal anti-clogging component filters and collects sediment under centrifugal force, reducing filter screen clogging.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: Reference Figure 1-4The diagram illustrates a water conservancy engineering construction anti-clogging pipeline, comprising a first pipeline 1 and a second pipeline 2. A centrifugal anti-clogging component is installed inside the first pipeline 1. This component uses centrifugal force to separate impurities in the water flow, reducing the risk of pipeline blockage. It includes a rotating cylinder 5 rotatably connected to the inner wall of the first pipeline 1. The rotating cylinder 5 rotates with the water flow, generating centrifugal force. A first spiral guide groove 14 is formed on the inner wall of the rotating cylinder 5, guiding the water flow along a spiral path to enhance the centrifugal effect. Multiple guide plates 6 are fixedly connected to the inner wall of the rotating cylinder 5, which can push the rotating cylinder 5 to rotate and further guide the flow. A filter screen 7 is fixedly connected to one end of the rotating cylinder 5 to intercept larger impurities. A backwashing component is installed inside the second pipeline 2 to clean the filter screen 7 and prevent it from clogging. The backwashing component includes components connected to the first pipeline 1... The inner wall of the second pipe 2 is fixedly connected to an annular vent pipe 9 for transporting gas. Multiple interconnected elastic duckbill jet nozzles 10 are fixedly connected to the outer side of the annular vent pipe 9, which can directionally spray high-pressure gas to backwash the filter screen 7. Multiple inclined plates 11 are fixedly connected to the outer side of the filter screen 7 to guide the backwash airflow and impurities, thereby improving cleaning efficiency. An air pump 3 is fixedly connected to the outer side of the second pipe 2 to provide air source for backwashing. The output end of the air pump 3 passes through the second pipe 2 and is fixedly connected to the annular vent pipe 9 to ensure stable gas delivery. Flanges 4 are provided on the outer sides of the first pipe 1 and the second pipe 2 for quick connection and fixation of the two pipes. A second spiral guide groove 8 is opened on the inner wall of the first pipe 1 to assist the water flow in forming a spiral motion and enhance the overall anti-clogging effect.

[0022] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a rotating ring 12 is fixedly connected to the outer side of the rotating cylinder 5. The rotating ring 12 can enhance the connection stability between the rotating cylinder 5 and the first pipe 1, while reducing the frictional resistance during rotation. A sliding groove 13 adapted to the rotating ring 12 is opened on the inner wall side of the first pipe 1. The sliding groove 13 provides a limiting guide for the rotating ring 12, ensuring that the rotating cylinder 5 rotates smoothly along a preset trajectory. The elastic duckbill jet head 10 is inclined and faces the inclined plate 11. The inclined setting can improve the directionality of the airflow jet, and facing the inclined plate 11 can make the jet airflow accurately act on the surface of the inclined plate 11, enhance the impact force to improve the cleaning or reaction efficiency, and the elastic characteristics can adapt to the airflow adjustment under different pressures.

[0023] The working principle of this utility model is as follows: Water flows through the first spiral guide channel 14 to generate swirling flow to separate mud and sand. The water flow impacts the guide plate 6, which drives the rotating cylinder 5 to rotate. The filter screen 7 filters the mud and sand, and the mud and sand are collected through the second spiral guide channel 8 and the annular collection frame 15. The air pump 3 controls the air pump to spray high-pressure gas through the annular air pipe 9 and multiple elastic duckbill jet nozzles 10 to wash the filter screen 7. At the same time, the inclined plate 11 drives the filter screen 7 and the rotating cylinder 5 to deflect, thereby increasing the backwashing range and reducing the clogging of the filter screen 7.
