Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment in thermal power plants, specifically to an air cooler unblocking device. Background Technology

[0002] When a generator is operating, the temperature of the core and coils gradually rises due to copper and iron losses. To slow down the aging of the coil insulation and extend its lifespan, the coil temperature must not exceed a certain value, such as 100℃. Therefore, measures must be taken to remove the heat generated by the coils and core in a timely manner to maintain the coil insulation temperature within the specified range. Currently, air coolers are commonly used. Air coolers use cooling water to cool the relatively hot air exiting the generator before sending it back into the generator, thus achieving the cooling process.

[0003] After a period of use, finned air coolers are prone to scale buildup due to water quality issues, which can clog copper tubes and affect cooling performance. Therefore, the air cooler tube bundles need to be cleaned when the unit is shut down. Currently, the cleaning method mainly involves personnel removing the sealing plates and using a long rod with a wire brush at the end to clean the horizontally arranged tube bundles. This cleaning method not only consumes a lot of manpower but also has low efficiency. Therefore, an air cooler cleaning device is urgently needed. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an air cooler unclogging device. The device adjusts the position of the hollow tube using a horizontal drive assembly and a vertical drive assembly. A second motor drives the hollow tube to move axially, allowing the hollow tube and wire brush to be inserted into the tube bundle for cleaning. This method saves manpower, time, and effort, and improves cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air cooler unclogging device, comprising a base plate and a hollow tube.

A rotating shaft 14 is rotatably mounted on the hollow housing 10, and a second gear 13 is mounted on the rotating shaft 14. The first gear 12 and the second gear 13 interact... The wheel 13 is meshed with the shaft 14, which extends through the hollow housing 10 at both ends and has a pair of third gears 15 at its ends. A pair of connecting rings 19 are rotatably mounted on the hollow housing 10, and a pair of fourth gears 18 are mounted on the connecting rings 19. The pair of third gears 15 mesh with the pair of fourth gears 18. Each fourth gear 18 has a threaded hole at its center. The hollow tube 20 has threads on its outer wall and is threaded to the pair of fourth gears 18. A wire brush 21 is mounted at one end of the hollow tube 20. The wire brush 21 is hollow and has multiple water outlets. 21-1, a water pipe 22 is connected to the other end of the hollow tube 20, and a water supply device is connected to the other end of the water pipe 22; the horizontal drive assembly includes a concave groove 4, a first motor 5, a slider 6, a threaded rod 7, and a connecting block 8. The concave groove 4 and the first motor 5 are disposed at the bottom of the top plate 3. The threaded rod 7 is rotatably disposed on the concave groove 4. The output end of the first motor 5 is connected to the threaded rod 7. The slider 6 is slidably disposed in the concave groove 4 and threadedly connected to the threaded rod 7. A through groove 4-1 is provided at the bottom of the concave groove 4. The connecting block 8 is slidably disposed in the through groove 4-1 and its top is connected to the slider 6. The bottom of the connecting block 8 is connected; the vertical drive component is a telescopic cylinder 9, which is located at the bottom of the connecting block 8, and the telescopic end of the telescopic cylinder 9 is connected to the hollow shell 10; a pair of first mounting slots are provided on the hollow shell 10, and a pair of first bearings 16 are provided in the pair of first mounting slots, and the rotating shaft 14 passes through the pair of first bearings 16 and is connected to the inner ring of the first bearings 16; a pair of second mounting slots are provided on the hollow shell 10, and a pair of second bearings 17 are provided in the pair of second mounting slots, and a pair of connecting rings 19 are connected to the inner ring of the pair of second bearings 17; multiple rollers are provided at the bottom of the base plate 1.

[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0021] In this utility model, the first motor 5, the second motor 11, and the telescopic cylinder 9 are all connected to an external electrical control system via wires. The above equipment and connection methods are all existing technologies and will not be described in detail here.

[0022] According to the instruction manual Figure 1-3 As can be seen, when using this utility model, firstly, the sealing plate of the air cooler is removed, and the device is moved next to the air cooler. Secondly, the horizontal position of the vertical drive component is adjusted by the horizontal drive component, and then the height of the hollow shell 10 is adjusted by the vertical drive component so that the wire brush 21 is aligned with the tube bundle. Thirdly, the second motor 11 located inside the hollow shell 10 is started. The output end of the second motor 11 drives the connected first gear 12 to rotate. The first gear 12 drives the second gear 13 meshing with it to rotate. The second gear 13 drives the connected rotating shaft 14 to rotate. The rotating shaft 14 drives a pair of third gears 15 at its end to rotate. The pair of third gears 15 drives a pair of fourth gears 18 meshing with it to rotate. When the four gears 18 rotate, they drive the connecting ring 19 to rotate on the hollow shell 10, simultaneously causing the hollow tube 20, which is threaded to it, to move. The hollow tube 20 then drives the wire brush 21 to insert into the tube bundle. Finally, the external water supply device is activated, supplying water to the hollow tube 20 through the water pipe 22. The water is then sprayed out from the multiple outlets 21-1 on the wire brush 21 to clean the inside of the tube bundle. This utility model adjusts the position of the hollow tube 20 through the horizontal drive assembly and the vertical drive assembly. The second motor 11 drives the hollow tube 20 to move axially, causing the hollow tube 20 and the wire brush 21 to insert into the tube bundle for cleaning. This saves manpower, time, and effort during cleaning, and improves cleaning efficiency.

[0023] One possible implementation is that when the output end of the first motor 5 rotates, it drives the connected threaded rod 7 to rotate. The threaded rod 7 drives the slider 6, which is threaded to it, to slide in the concave groove 4. The slider 6 drives the connecting block 8, which is connected to it, to move. The connecting block 8 drives the vertical drive assembly at the bottom to move. The vertical drive assembly drives the hollow shell 10 to move, thereby adjusting the position of the hollow tube 20.

[0024] One possible implementation is that the vertical drive component is a telescopic cylinder 9, which is located at the bottom of the connecting block 8. The telescopic end of the telescopic cylinder 9 is connected to the hollow housing 10. When the telescopic end of the telescopic cylinder 9 extends or retracts, it drives the connected hollow housing 10 to move, thereby adjusting the vertical height of the hollow tube 20.

[0025] One possible implementation is that the hollow housing 10 has a pair of first mounting slots, and a pair of first bearings 16 are installed in the pair of first mounting slots. The rotating rod passes through the pair of first bearings 16 and is connected to the inner ring of the first bearings 16. The rotating shaft 14 is rotatably mounted on the hollow housing 10 through the pair of first bearings 16, which can reduce the friction between the rotating shaft 14 and the hollow housing 10 when the rotating shaft 14 rotates.

[0026] One possible implementation is that a pair of second mounting slots are provided on the hollow housing 10, and a pair of second bearings 17 are provided in the pair of second mounting slots. A pair of connecting rings 19 are connected to the inner rings of the pair of second bearings 17, and the pair of connecting rings 19 are rotatably mounted on the hollow housing 10 through the pair of second bearings 17.

[0027] One possible implementation is that the bottom of the base plate 1 is provided with multiple rollers to facilitate the movement of this utility model.
