Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for condenser pipes. Background Technology

[0002] During operation, scale easily accumulates inside the pipes of a condenser. Thick scale buildup can affect heat transfer efficiency, necessitating regular cleaning. According to patent application publication number CN116839411A, a condenser pipe cleaning device is disclosed. This device includes a cleaning mechanism with a cleaning brush for cleaning the condenser pipes. The cleaning brush comprises a brush body and impeller mechanisms at both ends of the brush body. The impeller mechanism has a fixing part for fixing the cleaning brush, the diameter of which is larger than the rotating shaft, and a first turbulence section is formed between the fixing part and the rotating shaft. In use, the cleaning mechanism moves within the pipe under the action of water flow. Simultaneously, the impeller mechanism drives the cleaning mechanism to rotate, causing the cleaning brush to rotate in a spiral linear motion. During this spiral rotation, the brush body contacts the pipe wall.

[0003] However, existing cleaning devices require water flow to move the equipment during pipeline cleaning, but the driving force of the water flow is limited, resulting in limited cleaning effectiveness and incomplete cleaning. Therefore, improvements to the existing technology are needed. Utility Model Content

[0024] Please see Figure 1 , Figure 4 The locking mechanism 7 includes a locking wheel 71. The locking wheel 71 is fixedly connected to the outer side of the threaded sleeve 3. A fixing plate 72 is fixedly connected to the right side of the outer side of the rotating tube 2. A connecting rod 73 is slidably connected inside the fixing plate 72.
