Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a high-pressure water rotary nozzle for pipeline cleaning. Background Technology

[0002] Pipeline cleaning refers to the process of cleaning pipelines to ensure equipment safety and extend their service life. Pipelines used for a long time accumulate sludge, rust, and sediment, which can not only reduce pipe diameter and cause blockages, but also produce harmful gases such as hydrogen sulfide, posing safety hazards. There are various pipeline cleaning methods, commonly including chemical cleaning, high-pressure water cleaning, and PIG cleaning. Chemical cleaning uses circulating chemical agents, offering high flexibility and thorough cleaning. High-pressure water cleaning uses high-pressure water jets to remove dirt, offering speed and low cost. PIG cleaning uses fluid to propel a pig inside the pipe, removing dirt and is suitable for long-distance pipeline cleaning. After cleaning, the pipe's surface can be restored to its original condition, forming a passivation film to prevent dirt regeneration. Taking urban water supply pipelines as an example, cleaning can improve transportation efficiency, reduce energy consumption, and ensure water quality, benefiting residents' health.

[0003] When cleaning the inside of pipes, the flexible water pipes make it difficult for the nozzles to effectively rinse the pipe walls. When using high-pressure water jet cleaning, the flexible water pipes are prone to deformation and bending due to water pressure, making it difficult to maintain stable nozzle direction and continuously target specific areas of the pipe walls for effective rinsing. Furthermore, the flexible water pipes may sway within the pipe, causing the water flow from the nozzles to disperse and fail to concentrate its force on washing away dirt, thus affecting the cleaning effect. To address these technical problems, this application proposes a high-pressure water rotary nozzle for pipe cleaning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-pressure water rotary nozzle for pipe cleaning. The extension block slides on the slide rod by rotating the adjustment knob. Rotating the adjustment knob can retract the pull rope to allow the nozzle to enter the pipe. When the knob is released, the spring force pushes the nozzle to fit against the inner wall of the pipe, avoiding loss of direction due to deformation or bending of the soft water pipe, and allowing the water flow to concentrate and flush away dirt.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-pressure water rotary nozzle for pipeline cleaning includes a connecting rod. Two sliding rods are fixedly connected to the right side of the connecting rod. An extension block is slidably connected to the outer wall of the two sliding rods. Two sliding grooves are formed on the left side of the extension block. The right sides of the inner walls of the two sliding grooves are connected by a limiting component to allow the extension block to slide on the sliding rod. A nozzle is fixedly connected to the left side of the extension block. A clamping tube is fixedly connected to the outer wall of the nozzle. Multiple clamping blocks are fixedly connected to the inner wall of the clamping tube. The tops of the multiple clamping blocks on adjacent sides are connected by an adjusting component to adjust the spacing between the bottoms of the multiple clamping blocks on adjacent sides.

[0006] Furthermore, the limiting component includes a pull rope fixedly connected to the right side of the inner wall of the slide groove, and a winding rod rotatably connected to the right side of the connecting rod, with the outer wall of the winding rod fixedly connected to the bottom end of the pull rope.

[0007] Furthermore, two rope tubes are fixedly connected to the right side of the slide rod, the outer wall of the rope tubes is inserted into the inner wall of the slide groove, and the outer wall of the pull rope penetrates the inner wall of the rope tubes.

[0008] Furthermore, an adjustment knob is rotatably connected to the right side of the connecting rod, and anti-slip stripes are provided on the outer wall of the adjustment knob. The left end of the adjustment knob is fixedly connected to the right end of the winding rod. A roller is rotatably connected to the inner wall of the connecting rod, and the outer wall of the roller abuts against the outer wall of the pull rope.

[0009] Furthermore, a spring is fixedly connected to the inner wall of the slide rod, and the right end of the spring is fixedly connected to the right side of the inner wall of the slide rod.

[0010] Furthermore, the adjusting assembly includes a push ring slidably connected to the inner wall of the clamping tube, the bottom end of the push ring abutting against the top of the side of the plurality of clamping blocks, and an adjusting ring fixedly connected to the top of the push ring. The clamping blocks are made of thermoplastic polyester elastomer.

[0011] Furthermore, a sealing ring is fixedly connected to the inner wall of the nozzle, and multiple sealing strips are fixedly connected to the outer wall of the sealing ring. A rotating rod is rotatably connected to the left side of the connecting rod.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the sliding of the extension block on the slide rod is adjusted by rotating the adjustment knob. Rotating the adjustment knob can rewind the pull rope to allow the nozzle to enter the pipe. When the knob is released, the spring force pushes the nozzle to fit against the inner wall of the pipe, avoiding loss of direction due to deformation or bending of the soft water pipe, and allowing the water flow to concentrate on flushing away dirt.

[0013] 2. In this utility model, the push ring pushes the clamping block to rotate to facilitate the connection of the water pipe. After the adjusting ring is released, the clamping block made of thermoplastic polyester elastomer springs back to clamp the water pipe. The sealing ring and sealing strip further improve the sealing of the connection, prevent water leakage, and ensure the effective use of high-pressure water flow. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a high-pressure water rotary nozzle for pipe cleaning, comprising a connecting rod 1, two sliding rods 2 fixedly connected to the right side of the connecting rod 1, extension blocks 3 slidably connected to the outer walls of the two sliding rods 2, two sliding grooves formed on the left side of the extension blocks 3, and a pull rope 13 fixedly connected to the right side of the inner wall of the sliding grooves, the pull rope 13 pulling the extension blocks 3 to slide along the sliding rods 2; a winding rod 16 is rotatably connected to the right side of the connecting rod 1, the outer wall of the winding rod 16 being fixedly connected to the bottom end of the pull rope 13, the rotation of the winding rod 16 pulling the pull rope 13... 3. Rewinding: Two rope tubes 12 are fixedly connected to the right side of the slide rod 2. The outer wall of the rope tube 12 is inserted into the inner wall of the slide groove. The outer wall of the pull rope 13 passes through the inner wall of the rope tube 12, protecting the pull rope 13 and increasing the stability of the extension block 3 during sliding. An adjustment knob 6 is rotatably connected to the right side of the connecting rod 1. The outer wall of the adjustment knob 6 has anti-slip stripes to increase friction and facilitate gripping. The left end of the adjustment knob 6 is fixedly connected to the right end of the winding rod 16. Rotating the adjustment knob 6 causes the winding rod 16 to rotate, and the rotation of the winding rod 16 winds up the pull rope 13. (Refer to...) Figures 5-7 A roller 17 is rotatably connected to the inner wall of the connecting rod 1. The outer wall of the roller 17 abuts against the outer wall of the pull rope 13, changing the direction of movement of the pull rope 13. A spring 14 is fixedly connected to the inner wall of the slide rod 2. The right end of the spring 14 is fixedly connected to the right side of the inner wall of the slide rod 2. The spring 14 releases its elastic force to push the extension block 3 and the nozzle 4 to slide. Reference Figures 1-3 A nozzle 4 is fixedly connected to the left side of the extension block 3, from which water is sprayed out; a clamping tube 5 is fixedly connected to the outer wall of the nozzle 4, and multiple clamping blocks 7 are fixedly connected to the inner wall of the clamping tube 5. The clamping blocks 7 clamp the water pipe to make the connection more stable; a push ring 8 is slidably connected to the inner wall of the clamping tube 5. The bottom end of the push ring 8 abuts against the top of the side of the multiple clamping blocks 7. An adjusting ring 10 is fixedly connected to the top of the push ring 8. Pushing the adjusting ring 10 causes the adjusting ring 10 to push the push ring 8 to slide; the clamping block 7 is made of thermoplastic polyester elastomer, which is a high-performance engineering-grade elastomer with advantages such as high mechanical strength, good elasticity, impact resistance, and creep resistance. Its elasticity and strength are between those of rubber and plastic, exhibiting excellent fatigue resistance and maintaining good elasticity even under repeated cyclic load conditions; the sliding push ring 8 pushes the clamping block 7 to rotate, releasing the adjusting ring 10, which rebounds to clamp the water pipe due to the characteristics of the clamping block 7; a sealing ring 9 is fixedly connected to the inner wall of the nozzle 4, and multiple sealing strips 11 are fixedly connected to the outer wall of the sealing ring 9. Simultaneously, the sealing ring 9 inserts into the inner wall of the water pipe, and the multiple sealing strips 11 press against the inner wall of the water pipe to increase the sealing performance; see reference. Figure 7 The left side of the connecting rod 1 is rotatably connected to the rotating rod 15, which makes the water pipe slide stably when sliding.

[0018] Working principle: When starting work, the water pipe is passed through the limiting ring on the left side of the connecting rod 1 to fix the water pipe. Push the adjusting ring 10 to push the push ring 8 to slide. The sliding of the push ring 8 pushes the clamping block 7 to rotate, connecting the water pipe to the bottom of the nozzle 4. Release the adjusting ring 10 and rely on the characteristics of the clamping block 7 to rebound and clamp the water pipe. At the same time, the sealing ring 9 is inserted into the inner wall of the water pipe and multiple sealing strips 11 abut against the inner wall of the water pipe to increase the sealing performance.

[0019] When it is necessary to insert the nozzle 4 into the pipe, rotate the adjusting knob 6 to rotate the winding rod 16. The rotating winding rod 16 winds up the pull rope 13, and the pull rope 13 pulls the extension block 3 to slide along the slide rod 2, allowing the nozzle 4 to enter the pipe. When it is necessary to clean the nozzle 4 against the inner wall of the pipe, slowly release the adjusting knob 6 to release the spring 14 and push the extension block 3 and the nozzle 4 to slide against the inner wall of the pipe to clean the pipe.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
