[0002] The application scope of HVAC pipes is very wide, including purification system return air ducts, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, mining rubber-coated air ducts, etc. After the HVAC pipes have been used for a certain period of time, a lot of scale will accumulate on the inner wall of the HVAC pipes. The thermal conductivity of scale is very poor, which will cause the heat transfer of the heated surface to deteriorate. Due to thermal expansion and contraction and uneven force, the risk of HVAC pipe rupture or even explosion is greatly increased. When scale is cemented, a large amount of heavy metal ions are often attached. If it is used to transport water, there is a risk of excessive dissolution of heavy metal ions in water.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the prior art, when cleaning HVAC pipes, brushes are mostly used for cleaning. In this process, due to the soft texture of the brush, the dirt adsorbed on the inner wall of the HVAC pipe cannot be effectively cleaned during the cleaning process. Utility Model Content

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a device for removing scale from building HVAC pipes, comprising a sleeve with an opening at one end, a sleeve rod being slidably arranged in the sleeve, a hand grip with a T-shaped cross section being fixedly arranged on the side wall of the sleeve, a plurality of accommodating grooves being opened on the side wall of the sleeve rod, a cleaning plate being installed in each of the plurality of accommodating grooves, and a control component for controlling the cleaning plate being arranged on the sleeve rod.
[0006] By adopting the above technical solution, when the staff needs to clean the scale in the pipeline, the staff needs to slide the sleeve rod into the pipeline. Then, the staff starts the control component, and then the cleaning plate is pressed against the inner wall of the pipeline under the action of the control component. At this time, the staff rotates the sleeve rod to make the cleaning plate clean the inner wall of the pipeline. In this process, the side wall of the cleaning plate is pressed against the inner wall of the pipeline to effectively clean the scale on the inner wall of the pipeline, thereby improving the cleaning efficiency.

[0011] Furthermore, a limiting groove is provided on the inner wall of the sleeve, a limiting block is slidably arranged in the limiting groove, and the limiting block and the sleeve rod are fixed to each other.
