[0002] The technology of trash rack cleaning originated from the need for trash racks in hydropower stations and pumping stations to intercept pollutants in the water. As pollutants accumulate, they lead to increased head loss, decreased equipment efficiency, and safety hazards. Traditional manual cleaning methods are inefficient and dangerous, while mechanical cleaning technology has gradually become the mainstream. Its development covers structural optimization, material upgrades, intelligent control, and multi-functional integration, aiming to achieve efficient, safe, and automated pollutant cleaning and ensure the stable operation of water conservancy facilities.

[0003] When trash rack blockage leads to excessive liquid level difference and reduced power generation efficiency, automatic trash rack cleaning machines are needed to ensure unobstructed water intake and stable power generation. Automatic trash rack cleaning machines are a product of the deep integration of water treatment engineering and automation control technology. They achieve solid-liquid separation by intercepting suspended solids in the fluid through mechanical grilles, and combine this with sensors to monitor the degree of blockage in real time and trigger an automated cleaning process. Furthermore, the use of corrosion-resistant materials and anti-winding design ensures stable operation of the equipment in complex underwater environments, ultimately achieving efficient, continuous, and intelligent trash rack cleaning, ensuring unobstructed water intake and power generation efficiency for hydropower stations. Existing cleaning machines are mostly fixed structures and cannot be dynamically adjusted according to the size and spacing of the trash rack bars, limiting their application on trash racks of different sizes, thus reducing work efficiency and practicality.

The cleaning plate 4 drives the spring column 5 to move together, which in turn drives the cleaning plate 6 to slide together. When it slides to a suitable distance, rotate the threaded column 12 to fix the sliding plate 11. When the cleaning plate 4 is inserted into the trash rack, due to the action of the spring column 5, the cleaning plate 4 and the cleaning plate 6 will be tightly attached to the inner wall of the trash rack, thus achieving the function of cleaning trash racks of different sizes, expanding the scope of application, improving work efficiency, and improving practicality.

[0042] First, press the pressing column 210 to make it slide in the connecting block 211, thereby pushing the push plate 212 downward, which in turn drives the sliding column 207 to slide along the slide groove 206. When it slides to the top of the inner wall of the slide groove 206, the rotating plate 204 rotates around the rotating shaft 205, thereby driving the hook 209 to rotate inward and insert it into the connecting block 201. Then release it. Due to the action of the spring column 203, the push plate 212 will return to its original position, so that the hook 209 returns to its original position and is locked in the slot 202. Press the pressing column 210 again to disassemble and remove it, thus achieving the function of quick disassembly of the parts, which facilitates the use of the staff, improves work efficiency, and enhances practicality.
