A plurality of blades 32 are provided and are evenly distributed along the circumferential direction of the driving rod 31.

[0039] See also Figure 3 The guide plate 33 is fixed obliquely in the water pipe 22. The function of the guide plate 33 is to allow the cooling water entering the water pipe 22 to impact the blade 32 on one side, thereby ensuring that the driving rod 31 rotates.

[0040] See also Figure 3 The transmission part 7 includes: a driving gear 71 and a driven gear 72. The driving gear 71 is coaxially sleeved on the end of the driving rod 31 away from the blade 32.

In this embodiment, a plurality of limiting rings 61 are provided, and the limiting rings 61 are arranged at intervals along the length of the serpentine tube 11. The function of the limiting ring 61 is to limit the pulling rope 62 so that the pulling rope 62 can be bent into the shape of the serpentine tube 11, so that the pulling rope 62 is not easily unable to pull the moving part 4 to move on the serpentine tube 11 due to being in a vertical state.

[0043] See also Figure 4The moving part 4 includes: a moving tube 41, a mounting shell 42, a rolling ball 43 and a telescopic spring 44. The moving tube 41 is sleeved on the serpentine tube 11. In this embodiment, the inner diameter of the limit ring 61 is larger than the outer diameter of the moving tube 41, so that the moving tube 41 can pass through the limit ring 61, thereby not easily affecting the movement of the moving tube 41; the end of the pulling rope 62 away from the pulling rod 63 is fixedly connected to the end wall of the moving tube 41.

[0044] See also Figure 4 The telescopic spring 44 is fixed between the mounting shell 42 and the bottom of the mounting hole 411. When the moving tube 41 moves to the curved section of the serpentine tube 11, part of the telescopic spring 44 is compressed so that the mounting shell 42 can be recovered into the mounting hole 411; part of the telescopic spring 44 is extended to push the rolling ball 43 to always abut against the serpentine tube 11, thereby ensuring that the moving tube 41 can smoothly pass through the curved section of the serpentine tube 11 to complete the trajectory movement of the entire serpentine tube 11.

[0045] See also Figure 3 and Figure 4 The covering part 5 includes: a fixed block 51, a rotating rod 52, a first coil spring 53, a connecting pipe 54 and a first thin hose 55.

[0046] See also Figure 3 and Figure 4 One end of the first thin hose 55 is connected to the water inlet hole 521 and is wound around the rotating rod 52, and the other end is connected to the water inlet chamber 412. During the movement of the moving tube 41, the cooling water in the spray pipe 23 simultaneously enters the water inlet hole 521 through the connecting pipe 54, and then enters the water inlet chamber 412 through the first thin hose 55, and finally sprays to the serpentine tube 11 through the water outlet hole 413, thereby ensuring that the cooling water can completely cover the serpentine tube 11 (except the starting section and the end section of the serpentine tube 11) to improve the cooling effect.

[0047] See also Figure 3 and Figure 4The first coil spring 53 is sleeved on one end of the rotating rod 52 located in the accommodating hole 512, and one end of the first coil spring 53 is fixed to the rotating rod 52, and the other end is fixed to the inner wall of the accommodating hole 512. After pulling the moving tube 41 to complete a trajectory movement from top to bottom, the water supply is stopped; at the same time, the first coil spring 53 restores its deformation to drive the rotating rod 52 to rotate, thereby retracting the first thin hose 55 to pull the moving tube 41 to the initial position; after recovery, the submersible pump 21 can be started again immediately, so that the moving tube 41 moves again, and this operation is repeated to efficiently cool the gas in the serpentine tube 11, and the cooling effect is better.

When the four cleaning plates 82 approach the moving tube 41, the four cleaning plates 82 will gradually approach and join together to surround the serpentine tube 11; until the cleaning plate 82 contacts the outer side wall of the serpentine tube 11, so that the cleaning plate 82 can scrape the outer side wall of the serpentine tube 11 to prevent dirt from being generated on the outer side wall of the serpentine tube 11, thereby not easily affecting the cooling effect.

[0050] See also Figure 3 and Figure 4 The connecting spring 83 is fixed between the pushing plate 81 and the cleaning plate 82. The connecting spring 83 can press the cleaning plate 82 onto the outer wall of the serpentine tube 11 to improve the scraping effect.
