[0020] The accompanying drawings in this utility model are all schematic diagrams and their sizes do not represent actual dimensions.

[0021] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] like Figures 1-4 As shown, a turbine runner blade cleaning device includes: a cleaning tank 1, with support legs 2 symmetrically arranged at the bottom of the cleaning tank 1, a placement door 7 hinged to the surface of the cleaning tank 1, a handle 8 fixedly connected to the surface of the placement door 7, a support rod 3 inside the cleaning tank 1, a support platform 4 fixedly connected to the top of the support rod 3, and drainage holes 5 and a sewage trough 6 respectively opened on the surface of the support platform 4, a turbine runner blade cleaning assembly 9 inside the cleaning tank 1, the turbine runner blade cleaning assembly 9 including a high-pressure water pump 901 fixedly installed at the bottom of the cleaning tank 1, a water outlet pipe 902 fixedly connected to the outlet of the high-pressure water pump 901, a cleaning ring 903 inside the cleaning tank 1, the water outlet pipe 902 connected to the cleaning ring 903, and water spray nozzles 904 evenly distributed inside the cleaning ring 903, the water spray nozzles 904 being oriented towards the center of the cleaning ring 903.

[0024] The turbine runner blades to be cleaned are placed on top of the support platform 4. The high-pressure water pump 901 is started, drawing cleaning fluid from the bottom of the cleaning tank 1 and sending it through the outlet pipe 902 into the cleaning ring 903. Finally, the fluid is sprayed out through the nozzles 904 to clean the turbine runner blades. Multiple nozzles 904 are used to thoroughly rinse the turbine runner blades, reducing cleaning dead zones. A second motor 910 drives the cleaning ring 903 to rotate, while a first motor 906 moves the cleaning ring 903 up and down, further adjusting the height and position of the nozzles 904 to improve the cleaning effect on the turbine runner blades and avoid cleaning dead zones.

[0025] To drive the cleaning ring 903 to move up and down, the turbine runner blade cleaning assembly 9 also includes a chute 905 on one side of the cleaning tank 1. A slider 908 is slidably connected within the chute 905. A first motor 906 is fixedly connected to the top of the cleaning tank 1, and a lead screw 907 is fixedly connected to the output shaft of the first motor 906. The lead screw 907 is rotatably connected within the chute 905 and threadedly connected to the slider 908. The cleaning ring 903 is mounted on the slider 908. The first motor 906 drives the lead screw 907 to rotate, which in turn drives the slider 908 to move up and down along the chute 905. The movement of the slider 908, in turn, drives the cleaning ring 903 and the spray nozzle 904 to move up and down, thereby thoroughly cleaning the turbine runner blades.

[0026] To further avoid cleaning dead zones on the turbine runner blades, a fixing frame 909 is fixedly connected to the surface of the slider 908. A second motor 910 is fixedly mounted on the surface of the fixing frame 909, and the output shaft of the second motor 910 is fixedly connected to the cleaning ring 903. The second motor 910 drives the cleaning ring 903 to rotate, thereby changing the angle of the spray nozzle 904 and further improving the cleaning effect on the turbine runner blades.

[0027] To filter the washed water, a filter plate 911 is fixedly connected inside the washing tank 1, and a third motor 913 is fixedly installed at the bottom of the washing tank 1. The output shaft of the third motor 913 is fixedly connected to the support rod 3. The third motor 913 drives the support platform 4 to rotate, which cooperates with the water spray nozzle 904 to wash the turbine runner blades. After being filtered by the filter plate 911, the washed water is drawn into the high-pressure water pump 901 for recycling.

[0028] To improve filtration efficiency, the filter plate 911 is inclined inside the cleaning tank 1, and a scraper 912 is fixedly connected to the surface of the support rod 3, with the scraper 912 fitting snugly against the top of the filter plate 911. Impurities washed off by the turbine runner blades are filtered by the filter plate 911, and the impurity particles fall down along the filter plate 911. The scraper 912 cleans the filter plate 911, preventing impurities from clogging it.

[0029] To prevent the high-pressure water pump 901 from becoming clogged, the high-pressure water pump 901 is located at the bottom of the filter plate 911, and a drain cover 914 is hinged to the surface of the cleaning tank 1. The drain cover 914 is opened to remove the impurities filtered by the filter plate 911.

[0030] To facilitate the addition of cleaning solution to the cleaning tank 1, the top of the cleaning tank 1 is open, and a drain valve is fixedly connected to the bottom of the cleaning tank 1. Open the drain valve to discharge the wastewater.

[0031] In summary, the turbine runner blade cleaning device provided in this embodiment has the following advantages: A turbine runner blade cleaning assembly 9 is provided. The turbine runner blades to be cleaned are placed on top of the support platform 4. The high-pressure water pump 901 is started, drawing cleaning fluid from the bottom of the cleaning tank 1 and sending it into the cleaning ring 903 through the outlet pipe 902. Finally, the fluid is sprayed out through the spray nozzles 904 to clean the turbine runner blades. The multiple sets of spray nozzles 904 ensure comprehensive rinsing of the turbine runner blades, reducing cleaning dead zones. A second motor 910 drives the cleaning ring 903 to rotate, and a first motor 906 drives the cleaning ring 903 to move up and down, further adjusting the height and position of the spray nozzles 904, thereby improving the cleaning effect on the turbine runner blades and avoiding cleaning dead zones.

[0032] In use, add cleaning fluid into the cleaning tank 1, open the placement door 7, place the turbine runner blades on the support platform 4, and start the third motor 913 to drive the scraper 912 and the support platform 4 to rotate, thereby causing the turbine runner blades to rotate. Start the high-pressure water pump 901, which draws out the cleaning fluid from the bottom of the cleaning tank 1 and sends it into the cleaning ring 903 through the outlet pipe 902. Finally, it sprays the fluid out through the spray nozzle 904 to clean the turbine runner blades. The multiple spray nozzles 904 are used to thoroughly rinse the turbine runner blades. The first motor 906 drives the lead screw 907 to rotate, which in turn drives the slider 908 to move up and down along the slide groove 905. The movement of the slider 908 drives the cleaning ring 903 and the spray nozzles 904 to move up and down, thereby thoroughly rinsing the turbine runner blades. The second motor 910 drives the cleaning ring 903 to rotate, thereby changing the angle of the spray nozzle 904 and further improving the cleaning effect on the turbine runner blades. The rinse water, after being filtered by the filter plate 911, is then pumped in by the high-pressure water pump 901 for recycling. Impurities washed off the turbine runner blades are filtered by the filter plate 911, and the impurity particles fall down along the filter plate 911. The scraper 912 cleans the filter plate 911 to prevent impurities from clogging it.
