Description

Technical Field

[0001] The present invention relates to the technical field of water tank cleaning, and particularly to a cleaning device for the inner wall of a barreled water tank. Background Art

[0002] With the continuous development of modern society and the improvement of people's living standards, most communities, campuses, or office buildings in modern society require barreled water. Barreled water is mainly collected and supplied by water tanks. Water tanks are divided into various water tank products such as fiberglass water tanks, stainless steel water tanks, glass water tanks with stainless steel liners, and seawater fiberglass water tanks. After the water tank has stored water for a long time, some sundries will be generated inside, which is likely to affect the quality of barreled water, and the inside of the water tank needs to be cleaned.

[0003] Since the volume of the water tank is relatively large, the existing water tank cleaning devices are usually not convenient for cleaning the inner walls around the water tank. People still need to manually scrub after flushing, making the cleaning process rather troublesome, consuming more time and labor, and having a low cleaning efficiency for the water tank. To solve the deficiencies of the existing technology, we propose a cleaning device for the inner wall of a barreled water tank. Summary of the Invention

[0041] It should be noted that the present invention is a cleaning device for the inner wall of a barrel-shaped water tank. When in use, visually estimate the approximate size of the water tank, and with the help of tools, rotate the first knobs 35 at the upper ends of the two first support plates 1 to drive the rotation of the first bevel gears 43 inside the first adjustment chutes 33. When the first bevel gears 43 rotate, the second bevel gears 44 on both sides of the lower ends of the first bevel gears 43 will rotate synchronously and in opposite directions, thereby driving the two third lead screws 36 to rotate synchronously and in opposite directions. The third sliding blocks 37 will also move synchronously and in opposite directions on the outer walls of the third lead screws 36 and in the middle of the first adjustment chutes 33. The second telescopic rods 38 will also perform corresponding telescopic activities to adjust the distance between the two support frames 5. Place the four support frames 5 on both sides of the upper end of the water tank, and respectively rotate the second knobs 40 on the outside of each support frame 5 to drive the rotation of the fourth lead screws 45 in the middle of the second adjustment chutes 39. When the fourth lead screws 45 rotate, the adjustment blocks 6 will move on the outer walls of the fourth lead screws 45, and then move on the outer walls of the support frames 5 and in the middle of the second adjustment chutes 39, driving the positioning plates 41 to move, so that the positioning plates 41 contact the outer wall of the water tank to limit the support frames 5, making the support frames 5 stably installed at the upper end of the water tank. Start the first motor 10 to drive the rotation of the first lead screw 8 between the two second support plates 2. The moving cross bar 3 will move on the outer wall of the first lead screw 8, and at the same time move between the two vertical slide rails 32 through the first sliding blocks 7 at both ends, driving the cleaning roller 4 to move, so that the cleaning roller 4 contacts the inner wall of one side of the water tank. Start the fifth motor 25 to drive the rotation of the roller core 26 and the cleaning roller 4 to clean the inner wall of one side of the water tank. Start the second motor 16 in the middle of the second mounting frame 12 to drive the rotation of the second lead screw 15, so that the second sliding block 14 will move on the outer wall of the second lead screw 15 and at the same time move in the middle of the horizontal slide rail 11, so that the cleaning roller 4 moves horizontally, moving from one end of the inner wall of the water tank to the other end. After cleaning one side, start the third motor 19 to drive the rotation of the rotating arm 18 through the connecting shaft 17 to adjust the direction of the cleaning roller 4, so that the cleaning roller 4 contacts the inner wall of the adjacent side of the water tank. Then start the first motor 10 again to drive the rotation of the first lead screw 8, and the moving cross bar 3 moves between the two vertical slide rails 32 to drive the cleaning roller 4 to move back and forth to clean the inner wall of the other side of the water tank. Repeat this process to clean the four side walls of the water tank, and then move to the middle. Start the fourth motor 20 to drive the rotation of the threaded sleeve 22, and the threaded rod 23 will move downward at the lower end of the threaded sleeve 22.
