[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a negative pressure dust suction channel is formed by starting the fan. The suction head sucks in debris and dust, which are filtered through the filter screen. The debris is collected in the collection box, and the air is discharged from the outlet. When the filter screen needs to be cleaned, the pull rod is pulled, which drives the baffle and compresses the spring, causing the plug block to disengage from the filter screen. The blocking block slides into the thin shell to prevent the baffle from resetting, and the filter screen can be removed for cleaning. After cleaning, the blocking block is pulled up, and the spring causes the plug block to re-insert into the filter screen to complete the fixation. This effectively avoids dust pollution and creates a more environmentally friendly working environment. At the same time, the filter screen cleaning operation is simple and easy to perform, requiring no complicated tools. It can quickly complete the cleaning and maintenance of the filter screen, ensuring the continuous and efficient operation of the fan and reducing equipment maintenance costs and time costs.

[0024] 2. In this utility model, a motor drives a rotating rod to rotate, which in turn drives a rotating shaft and scraper to remove debris from the surface of the expansion joint. At the same time, a pulley on the rotating rod drives a belt to rotate a second pulley, a rotating shaft, and a turntable. The turntable drives a connecting shaft to slide inside a hollow shell, causing the sliding rod and scraper to reciprocate. This achieves deep cleaning of debris inside the bridge expansion joint, effectively removing stubborn debris such as gravel and soil accumulated deep in the gaps. It compensates for the shortcomings of surface scraping alone, greatly improves the cleaning effect, and reduces the risk of bridge structural damage caused by debris blockage.

[0039] Working principle: During operation, cylinder 7 is first started, and the output end of cylinder 7 drives slider 8 to move, thereby moving connecting plate 9, fixing plate 10 and the cleaning and dust collection components on them to the appropriate position. Then, motor 12 in the cleaning component is started, and the output end of motor 12 drives rotating rod 13 to rotate. Rotating rod 13 drives rotating shaft 14 and scraper 15 to rotate. Scraper 15 initially scrapes away debris on the surface of bridge expansion joint.

When the filter screen 2 needs to be cleaned, the lever 31 is pulled, and the lever 31 moves the stop. The plate 32 compresses the spring 34 and simultaneously moves the plug block 33, causing the plug block 33 to detach from the filter screen 2. At this time, under the action of gravity, the blocking block 35 slides into the thin shell 3, preventing the baffle 32 from being pushed by the spring 34 to re-insert the baffle 32 and the plug block 33 into the filter screen 2. The filter screen 2 can then be removed for cleaning. After cleaning, pull the blocking block 35 upwards, and under the action of the spring 34, the plug block 33 will re-insert into the filter screen 2, completing the installation and fixing of the filter screen 2.
