DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0025] Reference Figures 1 to 6 , is an embodiment of the utility model, which provides a pipeline inner wall rust remover, including a driving component 100 and a rust removal component 200 arranged at the output end of the driving component 100, the supporting end of the driving component 100 is rollingly clamped on the inner wall of the pipeline to enable the driving component 100 to move on the inner wall of the pipeline, when the output end drives the rust removal component 200 to operate, a part of the grinding end of the rust removal component 200 is in rolling friction contact with the inner wall of the pipeline, and the other part is in static friction contact with the inner wall of the pipeline.

[0026] Specifically, the support end of the driving component 100 is used to fix the entire device on the inner wall of the pipe, and also provides a stable grinding support for the rust removal component 200. The driving component 100 is used to drive the rust removal component 200 to operate. The grinding end of the rust removal component 200 grinds the inner wall of the pipe. A part of the grinding end rolls and rubs with the inner wall of the pipe, which can break up the layered rust and shatter the condensed rust, so that the other part of the grinding end grinds the rust by static friction. The cooperation of the two improves the grinding efficiency and the grinding effect.

[0027] Furthermore, the grinding ends of the driving assembly 100 and the rust removal assembly 200 can be telescopically adjusted to adapt to pipes of different sizes, while also ensuring the stable movement of the driving assembly 100 in the pipe;

[0028] Furthermore, the support ends are evenly spaced on the driving assembly 100 to form a triangular support ring, and there are two such rings, which improves the moving effect of the driving assembly 100 to be more stable;

[0029] Furthermore, the control part of the rust removal component 200 contacts / separates from the surface of the grinding end, so that the grinding end switches between rolling friction and static friction with the inner wall of the pipe. By controlling the friction mode of the grinding end, on the one hand, the rust on the pipe wall can be better polished, and the contact part between the grinding end and the pipe wall can be changed to avoid having only one grinding end.

[0030] Furthermore, the surface of the grinding end is tangent to the inner wall of the pipe, which can avoid grinding interference between the grinding end and the pipe wall and reduce the problem of the grinding end getting stuck on the pipe wall during the grinding and rust removal process;

[0031] Furthermore, the grinding ends are evenly spaced on the rust removal component 200, and the number of the grinding ends is at least two, which can prevent the output end of the driving component from shaking, and also provide a guarantee for the stable movement of the driving component 100 on the pipe wall, and can also improve the grinding efficiency due to multiple grinding ends;

[0032] Furthermore, a fan 107 is provided on the output end of the driving component 100, and the fan 107 is arranged between the driving component 100 and the rust removal component 200. When the output end drives the fan 107 to operate, the airflow blows toward the rust removal component 200. The fan can blow the polished rust fragments out of the pipeline, and can also prevent excessive rust from remaining on the polishing end, and the rust from falling on the surface of the driving component 100.

[0033] For example, Figure 1-Figure 6As shown, the driving assembly 100 includes supporting feet 104, and the supporting feet 104 are formed into two groups in a circular array to fix the two ends of the frame 103 respectively. A motor 101 is installed in the frame 103, and the motor shaft 102 of the motor 101 extends out of one side of the supporting feet 104, and a fan 107 is installed on the surface of the supporting feet 104;

[0034] A screw sleeve 104a is provided at the end of each support leg 104, and a roller bracket 105a is provided on the screw sleeve 104a through a screw 106. The screw 106 and the screw sleeve 104a are threadedly connected, and the roller bracket 105a can be adjusted to be extended and retracted. The roller 105 installed on the roller bracket 105a contacts the inner wall of the pipeline, so that the driving component 100 moves on the inner wall of the pipeline;

[0035] Furthermore, the collar 201 on the rust removal component 200 is installed at the end of the motor shaft 102, the collar 201 is connected to one end of the sleeve rod 202, the other end of the sleeve rod 202 is sleeved with a connecting rod 204, a groove 202a is engraved on the sleeve rod 202, and a locking screw 204a is threadedly sleeved on the connecting rod 204, the locking screw 204a passes through the groove 202a, and its nut is located on the surface of the sleeve rod 202. When the locking screw 204a is tightened, the nut squeezes the surface of the sleeve rod 202, so that the connecting rod 204 is locked after being extended on the sleeve rod 202. The connecting rod 204 is also provided with scale grooves 204b at equal intervals, so that multiple connecting rods can be extended to the same length;

[0036] A grinding piece 203 is provided at the end of the connecting rod 204. It is worth mentioning that the grinding piece 203 is composed of a first rolling shaft 203-1, a second rolling shaft 203-2 and a grinding shaft 203-3 arranged on the connecting plate 203a, wherein the grinding shaft 203-3 is installed in the middle of the connecting plate 203a, and the first and second rolling shafts are installed on both sides. When the first rolling shaft is driven by the motor 101, it rolls and contacts with the inner wall of the pipe, and the grinding shaft 203-3 is tightened by the locking sleeve 203-3a to achieve static friction contact with the inner wall of the pipe to achieve grinding. It is worth mentioning that the locking sleeve 203-3a can be installed on the three rollers, so as to achieve long-term without having to replace the grinding piece, and can also achieve a better effect of grinding the inner wall of the pipe.
