Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline unblocking technology, and in particular to an unblocking device for boiler pipelines. Background Technology
[0002] Boiler pipes are mainly used to transport hot water and steam. Dissolved minerals in the water precipitate during heating or evaporation, forming scale. Scale adheres to the inner wall of the pipes. As the boiler pipes are used for a long time, scale will accumulate inside, causing blockages and reducing boiler thermal efficiency. Therefore, it is necessary to clean the scale inside the boiler pipes regularly. For example, patent CN219222377U discloses a boiler pipe inner wall cleaning device. The beneficial effect is that the main unit drives the inner shaft to rotate, the inner shaft drives the drill bit to rotate, and the drill bit drives the drill teeth to rotate. The drill teeth and the cleaning scraper break up and clean the water grooves on the inner wall of the pipe. However, the cleaning scraper cannot clean pipes of different diameters, and its adaptability is relatively poor. Utility Model Content

[0022] Example
[0023] See Figures 1 to 5 This utility model provides a boiler pipe unblocking device, including a sleeve 1, a mounting box 2, a scraper assembly 3, a moving balance assembly 7, and a power mechanism 11. The power mechanism 11 is installed inside the mounting box 2, which has several heat dissipation holes (not shown) for heat dissipation. The drive end of the power mechanism 11 is detachably connected to the scraper assembly 3. There are multiple sets of scraper assemblies 3, and different scraper assemblies 3 can be replaced according to the diameter of the pipe to be cleaned. The scraper assembly 3 includes a connecting shaft 4 and several spiral scrapers 5. The connecting shaft 4 is detachably connected to the drive end of the power mechanism 11. The spiral scrapers 5 are respectively fixed to the connecting shaft 4 by corresponding elastic connecting rods 6. The diameter of the spiral scrapers 5 in different scraper assemblies 3 is different, depending on the diameter of the pipe to be cleaned. The diameter of the spiral scraper 5 is changed through the connecting shaft 4, making the device suitable for scraping dirt from pipes of different diameters. In use, the spiral scraper 5 is attached to the inner wall of the pipe, and the power mechanism 11 drives the connecting shaft 4 to rotate and scrape the dirt from the inner wall of the pipe. The elastic connecting rod 6 has telescopic properties, which allows the spiral scraper 5 to fit more closely to the inner wall of the pipe. One end of the sleeve 1 is fixed to the mounting box 2. The sleeve 1 is sleeved on the outside of the drive end of the power mechanism 11, which serves as a protective function. The outer side of the sleeve 1 is sleeved with the moving balance component 7. Multiple sets of moving balance components 7 can be selected so that the central axis of the sleeve 1 is collinear with the central axis of the pipe, which facilitates the smooth movement of the scraper assembly 3 in the pipe and effectively scrapes the dirt hanging in the pipe. For easy operation, a handle 19 is connected to the mounting box 2.
[0024] See Figure 1 and Figure 2The power mechanism 11 includes a motor 12 and a drive shaft 13. The motor 12 is installed in the mounting box 2. The output end of the motor 12 is connected to the drive shaft 13. The drive shaft 13 is detachably connected to the connecting shaft 4. To facilitate the replacement of the scraper assembly 3, the end of the drive shaft 13 is provided with a threaded groove 14. The end of the connecting shaft 4 is provided with a screw 15. The screw 15 is threadedly connected to the threaded groove 14. The drive shaft 13 and the connecting shaft 4 can also be connected by bolts or clamps. The sleeve 1 is fitted onto the outside of the drive shaft 13. The drive shaft 13 is connected to the sleeve 1 through a bearing (not shown). The bearing (not shown) is set inside the sleeve 1. A sealing ring 20 is provided between the end of the drive shaft 13 and the end of the sleeve 1.
[0025] The movable balancing assembly 7 includes a connecting ring 8, several movable wheels 9, and several elastic connecting rods 10. The connecting ring 8 is threaded to the outside of the sleeve 1 to facilitate the replacement of the movable balancing assembly 7. One end of each of the elastic connecting rods 10 is fixed to the connecting ring 8 at equal intervals along the circumference. The free ends of each of the elastic connecting rods 10 are respectively connected to the corresponding movable wheels 9. In use, the movable wheels 9 roll on the inner wall of the pipe. The movable wheels 9 can be omnidirectional wheels.
[0026] The first elastic connecting rod 6 and the second elastic connecting rod 10 each include an outer rod 16, an inner rod 17 and a pressure spring 18. The inner rod 17 is slidably connected to the outer rod 16, and the pressure spring 18 is disposed inside the outer rod 16 and between the inner rod 17 and the outer rod 16.
[0027] In use, scraper assemblies 3 with spiral scrapers 5 of different diameters are connected to the end of the drive shaft 13 according to the pipe diameter. The scraper assembly 3 extends into the pipe. The motor 12 drives the connecting shaft 4 to rotate through the drive shaft 13. The connecting shaft 4 drives several spiral scrapers 5 to rotate. The spiral scrapers 5 rotate to scrape away the dirt on the inner wall of the pipe. The handle 19 is held to continuously push the scraper assembly 3 into the pipe. The moving wheel 9 of the moving balance assembly 7 rolls on the inner wall of the pipe to balance the scraper assembly 3, so that the spiral scrapers 5 can effectively contact the inner wall of the pipe, thereby improving the cleaning effect of dirt in the pipe.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
