Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, a descaling device for the inner wall of a condenser condenser tube 9 includes a main body, which includes a movable cylinder 2 and a rotating brush cylinder 3 located in the middle of the movable cylinder 2. Limiting rings 21 are fixed to both sides of the movable cylinder 2 via second connecting members. A plurality of rollers 22 are arranged around the movable cylinder 2. A first mounting platform 41 and a second mounting platform 42 are sequentially installed on both sides of the movable cylinder 2. A first drive motor 411 is installed on the first mounting platform 41, and the rotating brush cylinder 3 is drivenly connected to the output shaft of the first drive motor 411. A monitoring camera 421 is installed on the second mounting platform 42.

[0021] The rotating brush cylinder 3 includes several descaling platforms 31. Several descaling seats 32 are detachably connected to the descaling platforms 31 via a first connector. A descaling sponge brush 33 is installed on the descaling seats 32. Several cleaning nozzles 34 are also arranged between the descaling platforms 31 for spraying water and cleaning the inner wall of the pipe.

[0022] In this invention, a servo motor for driving the mobile cylinder 2 to move forward automatically is also installed inside the mobile cylinder 2. In this invention, the servo motor and the monitoring camera 421 are existing technologies.

[0023] Using the above structure, the device moves automatically on the inner wall of the condenser tube 9 via a servo motor and several rollers 22 arranged around the moving cylinder 2. Simultaneously, a monitoring camera 421 on the second mounting platform 42 at the front detects the movement of the inner wall of the condenser tube 9. Then, the first drive motor 411 drives the rotating brush cylinder 3 to rotate. Cleaning nozzles 34 on the surface of the rotating brush cylinder 3 spray cleaning fluid, while several descaling sponge brushes 33 on the rotating brush cylinder 3 automatically rotate and clean the surface of a section of the condenser tube 9 wall. This facilitates automatic descaling, improves the descaling effect, and increases the degree of automation. It eliminates the need for manual movement using tools, making it easier to move the main body of the device and significantly reducing the time required for descaling. By adding a rotatable rotating brush cylinder 3, it is beneficial to descale the inner wall of the condenser tube 9 while the main body of the device is moving within it, resulting in better descaling effect, higher work efficiency, and automatic, effective, and convenient descaling.

[0024] Specifically, such as Figures 1 to 4As shown, the outer surface of the limiting ring 21 has a sliding part 211, and several of the rollers 22 can simultaneously abut against the inner wall of the condenser tube 9.

[0025] With the above structure, the main body of the device is automatically moved within the condenser tube 9 by a servo motor and several rollers 22 arranged around the moving cylinder 2. This facilitates automatic descaling, reduces manual intervention, optimizes the workflow, and improves descaling efficiency.

[0026] like Figures 1 to 4 As shown, the first connector includes a first screw 5. The descaling platform 31 has a first threaded hole 51, and the descaling base 32 has a second threaded hole 52. The first screw 5 passes through the second threaded hole 52 and is threaded into the first threaded hole 51 of the descaling platform 31. The first screw 5 allows for flexible replacement of the descaling base 32, facilitating easy disassembly and assembly, and making it convenient to replace with a new, clean descaling sponge brush 33. Furthermore, tightening the descaling base 32 with the first screw 5 ensures a secure fixation.

[0027] like Figures 1 to 4 As shown, the descaling sponge brush 33 on the rotating brush cylinder 3 abuts against the inner wall surface of the condenser tube 9. This structure facilitates automatic rotation and descaling by the descaling sponge brush 33, resulting in a high degree of mechanization.

[0028] like Figures 1 to 4 As shown, sensors 6 are installed on both the first mounting platform 41 and the second mounting platform 42. By setting up sensors 6, the sensors 6 can detect the scale of solid impurities inside a section of the condenser tube 9 and transmit the signal to the main body of the device via an electrical signal. This causes the rotating brush 3 to rotate more or fewer times on the inner wall of that section of the condenser tube 9, depending on the scale of the solid impurities, thus greatly improving the quality and efficiency of descaling.

[0029] like Figures 1 to 4 As shown, the second connecting component is the second bolt 7, and the movable cylinder is fixed to the limiting ring 21 by means of the second bolt 7. Fixing the limiting ring 21 by the second bolt 7 helps to ensure a secure fixation and makes the structure more stable.

[0030] like Figures 1 to 4 As shown, the descaling sponge brush 33 has a brush groove 81 and a protrusion 82. By setting the brush groove 81 and the protrusion 82, it is beneficial to improve the quality and efficiency of descaling. Some hard-to-clean solid impurities will be effectively descaled by the cleaning part between the brush groove 81 and the protrusion 82, resulting in a better descaling effect.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0033] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
