[0002] At present, urban water supply mainly draws surface water, reservoirs, rivers, lakes and groundwater through water plant pumping stations. After being processed through sedimentation, disinfection, filtration and other process flows, it is finally transported to various users through distribution pumping stations and pipeline networks.

[0003] The water in the water supply pipe will often produce impurities again during the circulation process. These impurities mainly come from the long-term sedimentation of impurities in a small amount of tap water, the corrosion and detachment blocks formed by the disrepair of the tap water pipes, and the deterioration of water in a small amount of pipes with poor circulation. The larger solid impurities among them may affect the normal operation of the compressor water pump or instrumentation. Utility Model Content

[0016] Embodiment: A water supply pipeline maintenance device for a water conservancy project

[0017] like Figure 1-2 As shown, a water supply pipeline maintenance device for a water conservancy project, the specific structure of which includes:

[0018] A cylinder 1, water pipes 2 are integrally fixedly installed on both sides of the cylinder 1, connecting pipes 3 are respectively fixedly installed on both sides of the bottom surface of the cylinder 1, and the lower ends of the connecting pipes 3 are respectively integrally rotatably installed with internal threaded joints 4, and the two connecting pipes 3 are commonly connected to a U-shaped tube 5, and the two ends of the U-shaped tube 5 are respectively integrally fixedly installed with external threaded joints 6, and a filter screen 7 is fixedly installed in the U-shaped tube 5. A flow interception and reversing component is arranged in the cylinder 1, and the flow interception and reversing component can realize the guidance of water flow.

[0019] The intercepting and reversing assembly includes a column 8, the two ends of which are rotatably connected to the two sides of the inner wall of the cylinder 1 through sealed bearings, and L-shaped channels 9 are respectively opened on both sides of the interior of the column 8, one end opening of the L-shaped channel 9 is opposite to the two sides of the inner wall of the cylinder 1, and the other end openings of the L-shaped channel 9 are both facing the connecting pipe 3, and sealing rings 10 are fixedly installed on both sides of the inner wall of the cylinder 1, and the sealing ring 10 is located between the inner wall of the cylinder 1 and the outer side of the column 8, and a transmission assembly that can drive the column 8 to rotate is provided on the outside of the cylinder 1. When this structural design is in use, water entering the cylinder 1 from the left water pipe 2 can be discharged from the L-shaped channel 9 on the right through the U-shaped tube 5 and then through the L-shaped channel 9 on the left to enter the water pipe 2 on the right, thereby realizing water supply. After passing through the U-shaped tube 5, the water will be filtered by the filter 7, thereby intercepting larger impurities in the water and improving the water quality. When the U-shaped tube 5 is blocked, the column 8 is rotated by the transmission assembly, which can change the position of the opening of the L-shaped channel 9 at the bottom, so that the opening of the L-shaped channel 9 at the bottom is no longer aligned with the opening of the U-shaped tube 5, thereby realizing the cutoff of the water flow, which is convenient for the user to replace the U-shaped tube 5.

[0020] The transmission assembly includes a motor 11, which is electrically connected to a power source. A shell 12 is integrally fixedly installed on the top of the cylinder 1, and the shell 12 is communicated with the interior of the cylinder 1. The motor 11 is fixedly installed on one side of the shell 12, and the output shaft of the motor 11 passes through one side of the shell 12 and is rotatably connected to the shell 12 through a sealed bearing. A rotating shaft 13 is fixedly installed on the output end of the motor 11, and a gear 14 is fixedly installed on one end of the rotating shaft 13. An outer gear ring 15 meshing with the gear 14 is fixedly installed on the outer periphery of the column 8. When this structural design is in use, the shell 12 can increase the space at the top of the cylinder 1, and the output shaft of the motor 11 drives the connected shaft 13 to rotate, and the shaft 13 drives the outer gear ring 15 to rotate through the gear 14 connected to it, so that the column 8 rotates. When the U-shaped tube 5 needs to be replaced, the column 8 is rotated so that the opening below the L-shaped channel 9 faces the shell 12. At this time, the water entering the cylinder 1 from the left water pipe 2 can pass through the two L-shaped channels 9 and then enter the right water pipe 2, thereby ensuring the connectivity of the two water pipes 2, which will not affect their normal water supply and is convenient for users to replace the U-shaped tube 5.

[0021] A sealing pad is arranged inside the internal threaded joint 4. This structural design can increase the sealing performance when the internal threaded joint 4 is connected to the external threaded joint 6.

[0022] The motor 11 is a stepper motor, which has high control accuracy and is convenient for users to use.

[0023] The present solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in the present solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and the supporting motherboard, memory stick, storage medium and power supply are also included therewith, and the power supply is AC or a lithium battery; when a display screen is provided, a display card is also provided; for the operating principle of the controller, please refer to "Principles of Automatic Control", "Principles of Microcontrollers and Application Simulation Cases" and "Principles and Applications of Sensors" published by Tsinghua University Press, and other books in the field can be used for reference; other automatic controls and electrical devices not mentioned are all knowledge well known to those skilled in the art and will not be repeated here.

[0024] In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
