[0023] The locking mechanism includes a plurality of sliders 8, which are evenly fixedly connected to the outer wall of the upper fixed column 4 extending to the inner part of the lower fixed column 3. The sliders 8 are of a diamond structure. A plurality of card plates 9 are fixedly connected to the inner part of the lower fixed column 3. The sliders 8 are respectively located between the card plates 9. The bottom sides of the card plates 9 are gradually recessed toward the middle. A plurality of inclined guide plates 10 are fixedly connected to the lower side of the inner wall of the lower fixed column 3. Different parts disassembled during maintenance of the rotary drum filter are placed on the storage tray 7 respectively. By pressing the storage tray 7, the upper fixed column 4 is fixed and released by the locking mechanism after movement, so that the storage tray 7 can be moved and fixed in the storage slot 2, so that the storage tray 7 cooperates with the inner wall of the storage slot 2 to cover the parts inside, thereby preventing different parts from mixing or falling, which affects the labor intensity and maintenance efficiency of the staff during maintenance.

[0024] Furthermore, the outer edge of the top of the storage tray 7 is gradually recessed toward the middle thereof, and the outer edge of the top of the storage tray 7 is gradually recessed toward the middle thereof and then extends upward to bulge; the recessed portion of the storage tray 7 allows small-volume parts to be placed around the bulge in the middle when placed on the top thereof, thereby preventing small-volume parts of the same batch from piling up together, making it convenient for subsequent staff to take the parts, and the staff can release the storage tray 7 by pressing the bulge in the middle of the storage tray 7, thereby preventing the parts placed on the storage tray 7 from hindering the staff from pressing to release the storage tray 7.

[0025] Furthermore, a rubber disk 11 is fixedly connected to the top depression of the storage tray 7 and a plurality of disk needles 12 are evenly arranged on the top of the rubber disk 11.

[0028] Working principle: This embodiment provides a maintenance tool for a rotary drum filter. When in use, different parts disassembled during maintenance of the rotary drum filter are placed on the storage tray 7 respectively. The staff presses the storage tray 7 so that the storage tray 7 squeezes the upper fixing column 4 and moves to the lower side of the storage tank 2;

[0029] When the storage tray 7 squeezes the upper fixed column 4 to move, the upper fixed column 4 will synchronously drive the connecting plate 5 and the slider 8 to move downward. After the slider 8 moves, it will contact the inclined guide plate 10, and as the slider 8 moves, the slider 8 will extend the guide plate 10 and start to rotate. When the connecting plate 5 moves, it will squeeze the spring 6, and then stop pressing the storage tray 7. At this time, the spring 6 will start to push the upper fixed column 4 upward through the connecting plate 5 under its own elastic force. Since the slider 8 rotates, when the slider 8 moves upward, the top of the diamond-shaped slider 8 will be blocked by the concave part at the bottom of the card plate 9, so that the upper fixed column 4 cannot move upward, so that the storage tray 7 cannot move upward, so that the storage slot 2 and the storage tray 7 cooperate to cover different parts respectively.

[0030] Similarly, by pressing the storage tray 7 again, the slider 8 will rotate again, so that the slider 8 cannot be stuck by the clamping plate 9, but is reset and moved between the clamping plates 9, so that the storage tray 7 is moved up and reset, making it convenient for the staff to take the parts.

[0031] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
