Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0019] Combined with appendix Figure 1 To be continued Figure 5 A ash cleaning device for power plant boilers includes a base 1, a boiler body 2 connected above the base 1, a support frame 3 connected above the boiler body 2, an adjustment mechanism 4 connected above the middle of the support frame 3, a support rod 5 connected below the adjustment mechanism 4, mounting rods 6 connected to the left and right sides of the support rod 5, clamping mechanisms 7 connected to the outer sides of the two sets of mounting rods 6, and cleaning brushes 8 connected between the two sets of clamping mechanisms 7.
[0020] Furthermore, the clamping mechanism 7 includes a first rotating plate 701, which is connected to the mounting rod 6. Support columns 702 are connected to the four sides of the front side of the first rotating plate 701. A second rotating plate 703 is connected above the support columns 702. A sliding plate 704 is provided below the second rotating plate 703. There are three sets of sliding plates 704, which are respectively connected between the second rotating plate 703 and the first rotating plate 701. Clamping rods 705 are slidably connected inside the three sets of sliding plates 704. A movable rod 706 passes through the upper end of the clamping rod 705. The movable rod 706 is connected to the mounting rod 6. Clamping blocks 707 are respectively connected to the lower ends of the three sets of clamping rods 705. Furthermore, a fixing block 708 is connected to the upper end of the first rotating plate 701. A fixing seat 711 is provided above the fixing block 708. A driving rod 709 is provided inside the fixing seat 711. A driving block 710 is connected to the upper left side of the driving rod 709. A driving device 712 is connected to the right side of the driving rod 709. The driving device 712 drives the first rotating plate 701 to rotate, and further drives the second rotating plate 703 to rotate simultaneously. When the second rotating plate 703 rotates, it drives the three sets of sliding plates 704 to rotate, so that the sliding plates 704 slide on the clamping rod 705, and further drives the clamping rod 705 to rotate, thus fixing and clamping the cleaning brush 8. When it is necessary to disassemble the cleaning brush 8, similarly, the driving device 712 is rotated in the opposite direction, which drives the driving rod 709 to rotate in the opposite direction, and further drives the clamping rod 705 to rotate in the opposite direction, thus releasing the cleaning brush 8 from the fixation.
[0021] Furthermore, the adjustment mechanism 4 includes a mounting frame 401, with a drive motor 402 connected above the mounting frame 401. The output end of the drive motor 402 passes through the mounting frame 401 and is connected to a cylinder 403. An adjustment rod 404 is connected below the cylinder 403. The adjustment rod 404 passes through a support frame 3 and is connected to a support rod 5. The cylinder 403 drives the adjustment rod 404 to move, which in turn drives the support rod 5 to move inside the boiler body 2. The drive motor 402 drives the support rod 5 to rotate through the cylinder 403, allowing it to rotate while being adjusted up and down. The cleaning brushes 8 on both sides of the mounting rod clean the inside of the boiler body 2.
[0022] Furthermore, the support frame 3 has fixed plates 9 extending from its left and right sides respectively. Electric push rods 10 are connected to the bottom of the two sets of fixed plates 9 respectively. Support seats 11 are connected to the bottom of the two sets of electric push rods 10 respectively.

The height of the support frame 3 can be adjusted by driving the electric push rods 10, thereby improving the ease of operation.
[0023] Furthermore, a support leg 13 is connected to the lower part of the base 1.
[0024] The specific implementation of this utility model is as follows: First, the universal wheels 12 are moved to a suitable position. Then, the electric push rod 10 drives the support frame 3 to adjust its height, so that the support frame 3 is located above the boiler body 2. The cylinder 403 drives the adjusting rod 404 to move, further driving the support rod 5 to move inside the boiler body 2. The drive motor 402 drives the support rod 5 to rotate through the cylinder 403, so that it can rotate while being adjusted up and down. The cleaning brushes 8 on both sides of the mounting rod clean the inside of the boiler body 2. The drive device 712 drives the first rotating plate 701 to rotate, further driving the second rotating plate 703 to rotate simultaneously. When the second rotating plate 703 rotates... When plate 703 rotates, it drives the three sets of sliding plates 704 to rotate, causing the sliding plates 704 to slide on the clamping rod 705, further driving the clamping rod 705 to rotate and fix the cleaning brush 8. When it is necessary to disassemble the cleaning brush 8, similarly, the drive device 712 rotates in the opposite direction, driving the drive rod 709 to rotate in the opposite direction, further causing the clamping rod 705 to rotate in the opposite direction, releasing the cleaning brush 8 from fixation. This makes it easier to adjust the cleaning brush and facilitates its disassembly and replacement, improving operational convenience, further improving the ash removal effect, preventing excessive wear of the cleaning brush due to prolonged use, effectively removing ash accumulation inside the boiler, and improving the boiler's thermal efficiency.
