However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0024] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides a HVAC pipeline scale removal device, including a mounting tube 1, a mounting groove 2 is provided on one side of the outer wall of the mounting tube 1, a rotating shaft 3 is movably inserted into the inner surface wall of the mounting groove 2, a driving motor 4 is fixedly connected to one side of the outer wall of the rotating shaft 3, a rotating column 5 is fixedly connected to one side of the outer wall of the rotating shaft 3, a first mounting ring 6 is movably sleeved on the outer wall of the rotating column 5, a group of first mounting seats 7 are fixedly installed on the outer walls of the rotating column 5 and the first mounting ring 6, a first movable groove 8 is provided on one side of the outer wall of the two groups of first mounting seats 7, a first movable groove 8 is provided on the inner surface wall of the two groups of first movable grooves 8, a first movable rod 9 is movably inserted into the inner surface wall of the two groups of first movable rods 9, and a first connecting rod 10 is movably sleeved on the outer wall of the two groups of first movable rods 9 A connecting groove 11 is provided on one side of the outer wall of the two groups of first connecting rods 10, and a second movable rod 12 is movably inserted between the inner walls of the two groups of connecting grooves 11. A second movable groove 13 is provided on one side of the outer wall of the two groups of first connecting rods 10, and a third movable rod 14 is movably inserted into the inner walls of the two groups of second movable grooves 13. The outer walls of the two groups of third movable rods 14 are movably sleeved with a second mounting seat 15, and a sliding groove 16 is provided on one side of the outer wall of one of the two groups of second mounting seats 15. A brush plate 17 is fixedly installed between the tops of the two groups of second mounting seats 15, and a plurality of threaded grooves 18 are provided on the outer wall of the rotating column 5, and a fixing bolt 19 is threadedly connected to the inner wall of one of the plurality of threaded grooves 18.
[0025] The effect achieved by the entire embodiment 1 is that, when facing HVAC pipes of different diameters, the fixing bolts 19 are first loosened, and then the first mounting ring 6 is pushed to move left and right. The movement of the first mounting ring 6 drives a group of first connecting rods 10 on its top to move synchronously. The movement of this group of first connecting rods 10 will further push a group of third movable rods 14 to move in a group of sliding grooves 16, so that the angle of this group of first connecting rods 10 changes, and a connecting groove 11 is opened on one side of the outer wall of the two groups of first connecting rods 10, and a second movable rod 12 is movably inserted between the inner surface walls of the two groups of connecting grooves 11, and the second movable rod 12 The two adjacent first connecting rods 10 are movably connected together. Therefore, when the angle of one group of first connecting rods 10 changes, the other group will also be adjusted accordingly, and jointly push the brush plate 17 to move to adapt to the inner wall of the pipe with different diameters. When the brush plate 17 fits tightly against the inner wall of the HVAC pipe, the fixing bolt 19 is screwed into the corresponding threaded groove 18, and then the drive motor 4 is started. The output end of the drive motor 4 will drive the rotating shaft 3 and the rotating column 5 to rotate, thereby causing a group of brush plates 17 to rotate at high speed. In this way, a group of brush plates 17 can effectively remove scale from the inner wall of the pipe, ensuring the smooth and efficient operation of the pipe.
[0026] Embodiment 2, as Figure 2-Figure 5As shown, two groups of first fixing seats 20 are fixedly installed on the outer wall of the mounting tube 1, and the inner walls of the two groups of first fixing seats 20 are movably inserted with fourth movable rods 21, and the outer walls of the two groups of fourth movable rods 21 are movably sleeved with second connecting rods 22, and the inner walls of the two groups of second connecting rods 22 are movably inserted with fifth movable rods 23, and the outer walls of the two groups of fifth movable rods 23 are movably sleeved with second fixing seats 24, and arc plates 25 are fixedly installed between the tops of the two groups of second fixing seats 24, and two rollers 26 are fixedly installed on the top of one group of arc plates 25, and a threaded rod 27 is fixedly connected to one side of the outer wall of the mounting tube 1, and the outer wall of the threaded rod 27 is threaded A nut 28 is connected, and the outer wall of the threaded rod 27 is movably sleeved with a second mounting ring 29, and the outer wall of the second mounting ring 29 is fixedly installed with a group of third fixing seats 30, the inner walls of a group of third fixing seats 30 are movably inserted with a sixth movable rod 31, the outer walls of a group of sixth movable rods 31 are movably sleeved with a third connecting rod 32, the inner walls of a group of third connecting rods 32 are movably inserted with a seventh movable rod 33, the outer walls of a group of seventh movable rods 33 are movably sleeved with a fourth fixing seat 34, and the bottom of a group of arc plates 25 is fixedly connected to the top of a group of fourth fixing seats 34, and a fixing rod 35 is fixedly connected to one side of the outer wall of the threaded rod 27.
[0027] The effect achieved by the entire embodiment 2 is that, when facing HVAC pipes of different diameters, by accurately adjusting the nut 28, the second mounting ring 29 can be effectively pushed to move left and right in the horizontal direction. The movement of the second mounting ring 29 then drives a group of third connecting rods 32 to move accordingly. The movement of a group of third connecting rods 32 drives a group of arc plates 25 to move up and down. In this process, the two groups of second connecting rods 22 not only allow the height of the arc plates 25 to be adjusted, but also provide a stable support structure for a group of arc plates 25, ensuring the stability and reliability of the device during operation. The movement of a group of arc plates 25 drives the two groups of rollers 26 to fit tightly with the inner wall of the pipe, thereby enabling the device to move inside HVAC pipes of different diameters.
[0028] Working principle: First, the height of a group of brush plates 17 needs to be adjusted according to different pipe diameters. The operator needs to loosen the fixing bolts 19 first, and then push the first mounting ring 6 to move left and right. This action causes a group of first connecting rods 10 on the outer wall of the first mounting ring 6 to produce corresponding displacements. As the first connecting rods 10 move, a group of third movable rods 14 slide on the inner wall of the slide groove 16, thereby changing the angle of this group of first connecting rods 10. Since the two groups of first connecting rods 10 are movably connected by a group of second movable rods 12, when the angle of one group of first connecting rods 10 changes due to movement, the other group of first connecting rods 10 will be linked accordingly to ensure that the two groups of first connecting rods 10 can synchronously push a group of brush plates 17 for height adjustment to adapt to the inner walls of HVAC pipes of different diameters. When a group of brush plates 17 is tightly fitted against the inner wall of the HVAC pipe, the operator needs to retighten the fixing bolts 19. To the corresponding thread groove 18 to fix the position of a group of brush plates 17. Subsequently, the mounting tube 1 is placed inside the pipe, and the second mounting ring 29 is pushed to move by rotating the nut 28. The movement of the second mounting ring 29 drives a group of third connecting rods 32 to move synchronously. The movement of a group of third connecting rods 32 will push a group of arc plates 25 to adjust their positions. As the arc plates 25 move, the two groups of rollers 26 on the top thereof will gradually fit with the inner wall of the pipe. Under the action of the rollers 26, the device can move stably inside the pipe. At this time, the operator starts the drive motor 4, and the drive motor 4 will drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 further drives the rotating column 5 to rotate, and the rotating column 5 drives a group of brush plates 17 to rotate at high speed. In this way, the high-speed rotating brush can effectively remove the scale on the inner wall of the pipe and ensure the unobstructed flow of the HVAC pipe.
