[0023] REFERENCE Figure 1 The present embodiment provides a water supply device for an air cooler, which comprises a bearing assembly 1, the bearing assembly 1 comprising an air cooler 11 and a water supply pipeline 12 arranged at one end of the air cooler 11; and, a rotating assembly 2 arranged inside the water supply pipeline 12; and, a wall scraping assembly 3 comprising a mounting ring 31 arranged outside the rotating assembly 2, the wall scraping assembly 3 being driven without additional power, and only relying on the flow rate of the cooling water to drive the rotating assembly 2 to operate, realizing the linkage effect of "water flow driving + automatic scraping", reducing the energy consumption of the device, and avoiding the risk of failure caused by external power components such as motors.

[0024] The water supply pipeline 12 is arranged at one end of the air cooler 11 in an array, The real-time contact scraping of the wall scraping assembly 3 with the inner wall of the water supply pipeline 12 can effectively prevent the formation of stubborn dirt layer on the inner wall of the pipeline, avoid the attenuation of the cooling water flow caused by the reduction of the inner diameter of the pipeline, ensure the stability of the water inlet pressure and flow of the air cooler 11, and then maintain the cooling efficiency of the air cooler 11, thereby reducing the frequency of shutdown cleaning caused by pipeline blockage, reducing the maintenance cost of manual disassembly of the pipeline, avoiding damage to the inner wall of the pipeline caused by mechanical polishing during cleaning, and prolonging the overall service life of the water supply pipeline 12 and the air cooler 11.

[0025] Use process: when the air cooler 11 works for a long time, a large amount of impurities will adhere to the inner wall of the water supply pipeline 12 installed at one end of the air cooler 11. When the cooling water enters the water supply pipeline 12, the cooling water flows at a speed and contacts the rotating assembly 2, so that the rotating assembly 2 drives the wall scraping assembly 3 to rotate. After the wall scraping assembly 3 rotates, the wall scraping assembly 3 contacts the inner wall of the water supply pipeline 12 and scrapes the impurities on the inner wall.

[0026] Embodiment 2, refer to Figures 1-5 The second embodiment of the present application is different from the previous embodiment in that the rotating assembly 2 further comprises a mounting shaft 21 arranged on the inner side of the water supply pipeline 12, and the outer side of the mounting shaft 21 is provided with a plurality of blades 22 arranged in a circular array on the outer side of the mounting shaft 21. The circular array design of the blades 22 uniformly distributes the water flow force on the outer side of the mounting shaft 21, ensures the stable rotation of the rotating assembly 2, avoids the shaking of the wall scraping assembly 3 caused by uneven water flow impact, and further ensures the uniform cleaning of the inner wall of the pipeline by the scraper 37, preventing local impurity accumulation.

[0027] The wall scraping assembly 3 further comprises a support rod 311 arranged on the outer side of the mounting ring 31, and the support rod 311 is arranged in a circular array on the outer side of the mounting ring 31. The outer side of the support rod 311 is provided with an adjusting ring 32, and the inner side of the adjusting ring 32 is provided with a sliding groove 321.

When there is a slight protrusion or depression on the inner wall of the pipeline, the first elastic member 352 can adjust the position of the bearing seat 36 by extruding the fixed block 35, so that the scraper 37 is always tightly attached to the inner wall, and the sticky impurities or stubborn dirt embedded in the depression can be completely scraped off.

[0030] Wherein, the wall scraping assembly 3 is triangular design, and when the scraper 37 is cleaning the inner wall of the water supply pipeline 12, the elastic potential energy of the first elastic member 352 on the outer side of the sleeve rod 351 extrudes the fixed block 35, so that the fixed block 35 at both ends extrudes the bearing seat 36 outward, and the bearing seat 36 after being extruded drives the scraper 37 to tightly adhere to the inner wall of the water supply pipeline 12, and generates a pushing force, thereby more effectively cleaning.

In the process of rotating the mounting ring 31, the mounting ring 31 will drive the adjusting ring 32 to rotate through the support rod 311. At this time, the adjusting ring 32 drives the support block 331 in the sliding groove 321 and the arc-shaped seat 33 to rotate. In the process of rotating, the arc-shaped seat 33 drives the first connecting block 34, the connecting rod 341 and the second connecting block 342 at one end to rotate. Finally, the second connecting block 342 drives the upper bearing seat 36 and the scraper 37 on the bearing seat 36 to rotate.
