[0007] Preferably, a partition plate is fixedly connected to the interior of the outer tube, and the bracket is sleeved on the outside of the inner tube. The partition plate can divide the interior of the outer tube into two parts, thereby improving the boosting effect of the booster pump.

[0008] Preferably, flanges are sleeved on the outside of the short tube and the inner tube, and fixing grooves are evenly spaced outside the flanges, so that the flanges facilitate the connection and installation of the short tube, the inner tube and the external pipeline.

[0009] Preferably, a conical plate is sleeved on the outside of the scraper, and the conical plate is slidably connected to the inner wall of the outer tube. The conical plate can increase the cleaning effect of the scraper on the inner wall of the outer tube.

[0020] The outside of the short tube 2 and the inner tube 3 are both sleeved with flanges 21, and the outside of the flange 21 is evenly spaced with fixing grooves. The flange 21 facilitates the short tube 2 and the inner tube 3 to be connected and installed with external pipelines. The left side of the outer tube 1 is connected with a booster pump 4. The booster pump 4 can increase the pressure of the liquid flowing inside the outer tube 1, thereby avoiding the problem of fluid being unable to flow due to high resistance.

[0021] A bracket 41 is fixedly connected to the right side of the boost pump 4, and bolts are threadedly connected to both ends of the outside of the bracket 41. The bracket 41 can fix the boost pump 4 to the external wall or components, and the bracket 41 is sleeved on the outside of the inner tube 3. A partition plate 42 is fixedly connected to the inside of the outer tube 1. The partition plate 42 can divide the inside of the outer tube 1 into two parts, thereby improving the boosting effect of the boost pump 4. A cleaning mechanism 5 is installed at the bottom of the boost pump 4.

[0022] See also Figure 3 and Figure 4 The cleaning mechanism 5 includes a wheel 51, a pull rope 52 is wound around the outside of the wheel 51, one end of the pull rope 52 is fixed to the outside of the wheel 51, and the other end is connected to the scraper 53, the scraper 53 can move by buoyancy, the outside of the scraper 53 is sleeved with a conical plate 531, and the conical plate 531 is slidably connected to the inner wall of the outer tube 1, the conical plate 531 can increase the cleaning effect of the scraper 53 on the inner wall of the outer tube 1, the scraper 53 is slidably connected to the inside of the outer tube 1, and is sleeved on the outside of the inner tube 3.

[0023] A short shaft 54 ​​is fixedly connected to the back of the wheel disc 51, and the short shaft 54 ​​can support the wheel disc 51. The back of the short shaft 54 ​​is connected to a limit plate 56 through a seat bearing. The limit plate 56 can support and install the wheel disc 51, and the top of the limit plate 56 is connected to the bottom of the booster pump 4. A torsion spring 55 is installed between the wheel disc 51 and the limit plate 56.

At the same time, the cleaning mechanism 5 is added to cooperate with the booster pump 4 to clean the inner wall of the outer tube 1 when the fluid is flowing for heat exchange to prevent impurities in the fluid from adhering to the inner wall of the outer tube 1, thereby preventing the impurities from increasing the resistance of the fluid flow.
