Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, specifically a top defrosting duct structure. Background Technology

[0002] When using ductwork for gas transport, to ensure the safety of the ductwork and prevent damage to the outside due to frost or snow, it is often necessary to use duct cleaning equipment for defrosting. Utility model patent application number CN202222837672.0 discloses a duct cleaning device. Through its cleaning components, it facilitates the removal of sludge and mud from inside the ductwork, significantly improving cleaning effectiveness and efficiency, thus enhancing the practicality of the duct cleaning device. The included clamping components allow for easy fixation of the duct cleaning device to the ductwork. In addition, the device can be fixed on pipes with different outer wall diameters, so that workers do not need to hold it for a long time when using it, which effectively improves the convenience of using the device. According to the publicly available technical solution, existing pipe cleaning equipment often consumes electricity when cleaning frost on the outside of the pipe, which is not conducive to saving energy. Furthermore, it cannot automatically adjust its movement direction according to the length of the duct when cleaning frost on the outside of the pipe, which is not conducive to ensuring the cleanliness of the frost and work safety.

[0003] Therefore, how to design the top defrosting duct structure has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a top defrosting duct structure to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for defrosting ducts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top defrosting duct structure, comprising a duct and a slide groove, a support assembly installed on the duct, the support assembly comprising a collar and a slide rod, a fixing assembly installed at the bottom of the collar, the fixing assembly comprising a protrusion and a slot, a movable assembly installed inside the slot, the movable assembly comprising a sliding plate and a magnetic block, a rotating assembly installed on the sliding plate, the rotating assembly comprising a rotating rod and a fan blade, cleaning assemblies installed on both sides of the collar, the cleaning assembly comprising a rotating ring one and a rotating ring two, and a rotating assembly installed on the cleaning assembly, the rotating assembly comprising a toothed ring one and a toothed ring two.

[0006] Furthermore, the collar is fitted onto the outer side of the duct, the slide groove is opened at the bottom of the duct, the slide rod is welded to the inner wall of the bottom of the collar, and the slide rod is stuck inside the slide groove.

[0007] Furthermore, the protrusion is integrally formed on the bottom of the collar, the slot is formed on the inner side of the protrusion and the collar, the slide is locked inside the slot, the length of the slot is greater than the length of the slide, and the width of the slide is equal to the width of the slot.

[0008] Furthermore, the magnetic blocks are welded to the inner walls at both ends of the slot, the slide plate is adsorbed and fixed to the outer side of one of the magnetic blocks, the top of the rotating rod is mounted on the slide plate through a bearing, and the fan blade is welded to the bottom of the rotating rod.

[0009] Furthermore, both sides of the collar are provided with ring grooves, and the first rotating ring and the second rotating ring are respectively installed on both sides of the collar. One side of the first rotating ring and the second rotating ring are installed on the inner side of the ring groove through bearings. The other end of the first rotating ring and the second rotating ring pass through the ring groove and extend to the outer side of the collar. The other side of the first rotating ring and the second rotating ring are clamped on the mesh plate of the air duct. The other side of the first rotating ring and the second rotating ring are provided with teeth.

[0010] Furthermore, the first toothed ring is welded to one side of the first rotating ring, and the second toothed ring is welded to one side of the second rotating ring. Both the first toothed ring and the second toothed ring are disposed inside the ring groove.

[0011] Furthermore, gears are bolted to both ends of the rotating rod, and the gears mesh with gear ring one or gear ring two respectively.

[0012] Furthermore, both the first and second rotating rings have grooves on their inner sides, and a chuck is installed on the inner side of the groove. The chuck is close to the outer side of the air duct, and the rotation axis of the chuck is not parallel to the center line of the air duct.

[0013] Beneficial effects: 1. When using this top defrosting duct structure, the collar is placed on the outer side of the duct, and the sliding rod is locked inside the groove. Natural wind blows and the fan blades rotate. The fan blades drive the gear to rotate through the rotating rod. The sliding plate is locked inside the groove and is attracted and fixed to one end of the groove by one of the magnetic blocks. This causes the sliding plate to drive the gear on the rotating rod to mesh with the gear ring. The gear drives the rotating ring to rotate through the gear ring. The rotating ring rotates on one side of the collar through the bearing and uses the teeth to clean the frost on the duct. At the same time, when the chuck in the groove rotates on the outer side of the duct, the tilt of the chuck causes the chuck to drive the rotating ring to move from the outer side of the duct to one end of the duct. The cleaning work does not consume electricity, saving energy.

[0014] 2. In use, when the rotating ring one moves to one end of the duct and the teeth are blocked by the mounting structure at one end of the duct, the fan blades are subjected to a large wind force. The torque of the wind pushing the fan blades is greater than the attraction of the magnetic block on one side of the slide plate. This causes the gear to move through the inclined surface thrust at the meshing point with the gear ring one. This causes the rotating rod to move the slide plate to the other end of the slot and be attracted and fixed by another magnetic block. The gear meshes with the gear ring two, which in turn drives the rotating ring two to rotate. The rotating ring two rotates in the opposite direction on the other side of the collar and moves in the opposite direction through the chuck in the groove. This allows it to move back and forth on the outside of the duct and perform defrosting work, which can improve the defrosting effect and automatically change the direction of movement, saving manpower.

[0015] 3. The top defrosting duct has a reasonable structural design, is highly efficient and convenient to use, and is suitable for defrosting ducts. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a top defrosting duct structure, including a duct 1 and a slide 2. A support assembly is installed on the duct 1. The support assembly includes a collar 3 and a slide rod 4. A fixing assembly is installed at the bottom of the collar 3. The fixing assembly includes a protrusion 5 and a slot 6. A movable assembly is installed inside the slot 6. The movable assembly includes a slide plate 9 and a magnet 10. A rotating assembly is installed on the slide plate 9. The rotating assembly includes a rotating rod 7 and a fan blade 8. The collar 3 has... A cleaning assembly includes a first rotating ring 13 and a second rotating ring 14. A rotating component is mounted on the cleaning assembly, comprising a first gear ring 15 and a second gear ring 16. The first gear ring 15 is welded to one side of the first rotating ring 13, and the second gear ring 16 is welded to one side of the second rotating ring 14. Both the first gear ring 15 and the second gear ring 16 are disposed inside the annular groove 12. Gears 11 are bolted to both ends of the rotating rod 7, and the gears 11 mesh with either the first gear ring 15 or the second gear ring 16. The first rotating ring... Both 13 and 14 have grooves 18 on their inner sides. A retaining wheel 19 is installed inside the groove 18, and the retaining wheel 19 is close to the outer side of the duct 1. The rotation axis of the retaining wheel 19 is not parallel to the center line of the duct 1. In use, the collar 3 is fitted onto the outer side of the duct 1, and the sliding rod 4 is engaged inside the sliding groove 2. Natural wind blows the fan blade 8, which rotates. The fan blade 8 drives the gear 11 to rotate via the rotating rod 7. The sliding plate 9 is engaged inside the slot 6 and is attracted and fixed to one end of the slot 6 by one of the magnetic blocks 10. This causes the slide plate 9 to drive the gear 11 on the rotating rod 7 to mesh with the gear ring 15. The gear 11 drives the rotating ring 13 to rotate through the gear ring 15. The rotating ring 13 rotates on one side of the collar 3 through the bearing and uses the teeth 17 to clean the frost on the air duct 1. At the same time, when the chuck 19 in the groove 18 rotates on the outside of the air duct 1, the tilt of the chuck 19 causes the chuck 19 to drive the rotating ring 13 to move towards one end of the air duct 1 on the outside of the air duct 1. The cleaning work does not require electricity, saving energy consumption.

[0025] In this embodiment, the collar is fitted onto the outer side of the duct 1, the slide groove 2 is formed at the bottom of the duct 1, the slide rod 4 is welded to the inner wall of the bottom of the collar 3 and is engaged inside the slide groove 2, the protrusion 5 is integrally formed at the bottom of the collar 3, the slot 6 is formed inside the protrusion 5 and the collar 3, the slide plate 9 is engaged inside the slot 6, the length of the slot 6 is greater than the length of the slide plate 9, the width of the slide plate 9 is equal to the width of the slot 6, and the magnetic block 10 is welded to the inner walls at both ends of the slot 6. The sliding plate 9 is adsorbed and fixed to the outer side of one of the magnetic blocks 10. The top end of the rotating rod 7 is mounted on the sliding plate 9 via a bearing. The fan blade 8 is welded to the bottom end of the rotating rod 7. Both sides of the collar 3 have annular grooves 12. Rotating ring one 13 and rotating ring two 14 are respectively mounted on both sides of the collar 3. One side of each rotating ring one 13 and rotating ring two 14 is mounted on the inner side of the annular groove 12 via a bearing. The other ends of each rotating ring one 13 and rotating ring two 14 pass through the annular groove 12 and extend to the outer side of the collar 3. The other side of ring 13 and rotating ring 14 is engaged with the mesh plate of duct 1. Both rotating ring 13 and rotating ring 14 have teeth 17 on their other sides. In use, when rotating ring 13 moves to one end of duct 1 and the teeth 17 are blocked by the mounting structure at one end of duct 1, preventing rotation, when the fan blade 8 is subjected to a large wind force, the torque of the wind-driven fan blade 8 will be greater than the attraction force of the magnetic block 10 on one side of the sliding plate 9. This causes the gear 11 to move through the inclined surface thrust at the meshing point with the toothed ring 15. The movement causes the rotating rod 7 to move the sliding plate 9 to the other end of the slot 6, where it is attracted and fixed by another magnetic block 10. The gear 11 meshes with the gear ring 16, which in turn drives the rotating ring 14 to rotate. The rotating ring 14 rotates in the opposite direction on the other side of the collar 3, and is driven to move in the opposite direction by the chuck 19 in the groove 18. This allows it to move back and forth on the outside of the duct 1 and perform defrosting work, which can improve the defrosting effect and automatically change the direction of movement, saving manpower.

[0026] In use, the top defrosting duct structure involves placing the collar 3 on the outer side of the duct 1 and engaging the slide rod 4 inside the slide groove 2. Natural wind blows, causing the fan blades 8 to rotate. The fan blades 8 drive the gear 11 to rotate via the rotating rod 7. The slide plate 9 is engaged inside the slot 6 and is fixed to one end of the slot 6 by a magnet 10. This causes the slide plate 9 to engage the gear 11 on the rotating rod 7 with the gear ring 15. The gear 11 then drives the rotating ring 13 to rotate via the gear ring 15. The rotating ring 13 rotates on one side of the collar 3 via a bearing, using the teeth 17 to clean the frost on the duct 1. Simultaneously, as the retaining wheel 19 in the groove 18 rotates on the outer side of the duct 1, its tilt causes it to move the rotating ring 13 towards one end of the duct 1. This cleaning process requires no electrical energy, saving energy. When the 3rd part moves to one end of the duct 1 and the tooth 17 is blocked by the installation structure at one end of the duct 1 and cannot rotate, when the fan blade 8 is subjected to a large wind force, the wind force will push the torque of the fan blade 8 to be greater than the attraction of the magnetic block 10 on one side of the slide plate 9. As a result, the gear 11 moves by the inclined surface thrust at the meshing point with the gear ring 15. This causes the rotating rod 7 to move the slide plate 9 to the other end of the slot 6 and be attracted and fixed by another magnetic block 10. The gear 11 meshes with the gear ring 16, which in turn drives the rotating ring 14 to rotate. The rotating ring 14 rotates in the opposite direction on the other side of the collar 3 and is driven to move in the opposite direction by the chuck 19 in the groove 18. This allows it to move back and forth on the outside of the duct 1 and perform defrosting work, which can improve the defrosting effect and automatically change the direction of movement, saving manpower.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
