[0002] In the daily operation of thermal power plants, various foreign materials such as coal deposits and ash may accumulate in the pipelines. The accumulation of these materials is usually caused by several factors: First, coal ash and incompletely burned coal blocks generated during the combustion process may accumulate in the pipelines, and over time, these materials may accumulate and form blockages. Second, acidic substances and other chemicals contained in the flue gas may react with the inner wall of the pipeline to form deposits that are difficult to remove. The accumulation of these foreign materials will seriously affect the smoothness of the pipeline, resulting in poor flue gas flow, which in turn reduces the efficiency of flue gas desulfurization and may increase the maintenance cost and operation risk of the equipment.

[0022] In order to make the above-mentioned objects, 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.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a thermal power plant pipeline dredging tool for dredging foreign matter accumulated in the thermal power plant pipeline to keep the pipeline unobstructed, such as for dredging coal accumulation in the pipeline, including a dredging rod 100, and a striking sleeve 200 movably sleeved on the outside of the dredging rod 100.

[0028] Specifically, the dredging rod 100 has a striking end 101 that can collide with foreign matter accumulated in the pipeline; the striking sleeve 200 has a striking surface 201 arranged in the same direction as the striking end 101, and the dredging rod 100 has a striking surface 105 arranged opposite to the striking surface 201. When in use, the striking end 101 of the dredging rod 100 first collides with the foreign matter accumulated in the pipeline, and then the striking surface 201 of the striking sleeve 200 hits the striking surface 105 of the dredging rod 100, applying an impact force to the dredging rod 100, and the impact force is transmitted to the striking end 101 of the dredging rod 100 and diverges outward, so that the foreign matter accumulated in the pipeline is broken or vibrated by the impact, and after repeated impacts by the dredging rod 100, the foreign matter accumulated in the pipeline begins to break from the impact point and expand outward, and finally the pipeline is dredged.

[0029] As a further improvement, the device also includes an elastic member 300, one end of which is connected to the dredging rod 100, and the other end of the elastic member 300 is connected to the striking sleeve 200, for maintaining a displacement gap between the striking surface 201 on the striking sleeve 200 and the struck surface 105 on the dredging rod 100 when the striking sleeve 200 is not subjected to external force.

[0030] As a further improvement, the dredging rod 100 has a dredging section 102 and a handheld section 103; the striking sleeve 200 is movably sleeved on the outside of the handheld section 103 of the dredging rod 100. When in use, the striking sleeve 200 replaces the handheld section 103 of the dredging rod 100 and becomes a new handheld component.

[0031] As a further improvement, at least one anti-dropping block 104 is provided on the hand-held section 103 of the dredging rod 100, and the anti-dropping block 104 is used to limit the striking sleeve 200 to prevent the striking sleeve 200 from falling off.

[0032] As a further improvement, the striking sleeve 200 also has a retracting surface 202 facing away from the striking surface 201, and the dredging rod 100 has a receiving surface 106 arranged opposite to the retracting surface 202. The receiving surface 106 is arranged on the anti-slip block 104 and on a side arranged opposite to the retracting surface 202, that is, the anti-slip block 104 is also used as a striking piece for receiving the striking sleeve 200.

[0033] When in use, the striking end 101 of the dredging rod 100 strikes against foreign matter in the pipe. Since some foreign matter is soft and sticky, the dredging section 102 of the dredging rod 100 is easily inserted into the foreign matter during the dredging rod 100 striking against the foreign matter. At this time, the dredging rod 100 is stuck by the foreign matter and is difficult to be pulled out. The device is provided with a striking sleeve 200 that is slidably matched with the dredging rod 100. When the dredging rod 100 is stuck by the foreign matter, the striking sleeve 200 is slid in the reverse direction so that the retreat surface 202 of the striking sleeve 200 collides with the receiving surface 106 of the dredging rod 100, exerting an outward pulling force on the dredging rod 100, thereby helping to pull out the stuck dredging rod 100.

[0034] Specifically, two anti-dropping blocks 104 are provided and arranged at intervals, and the striking sleeve 200 is slidably sleeved on the outside of the hand-held section 103 and is located between the two anti-dropping blocks 104 .

[0035] Specifically, the two outer end surfaces of the striking sleeve 200 are respectively a striking surface 201 and a retracting surface 202; the side of the anti-slip block 104 close to the striking surface 201 and facing the striking surface 201 is a striking surface 105; the side of the anti-slip block 104 close to the retracting surface 202 and facing the retracting surface 202 is a receiving surface 106.

[0036] In summary, the device is provided with a dredging rod 100 and a striking sleeve 200 that is slidably matched with the dredging rod 100. When in use, the striking sleeve 200 is held by hand to strike the knocking end 101 of the dredging rod 100 against the foreign matter accumulated in the pipeline. After the knocking end 101 collides with the foreign matter, the striking surface 201 of the striking sleeve 200 collides with the striking surface 105 of the dredging rod 100, thereby generating an impact force. The impact force is transmitted along the dredging rod 100 to the collision point between the knocking end 101 and the foreign matter and then radiates outwards, so that the pipeline is cleared. The foreign matter accumulated inside is broken or vibrated by the impact, and the interval between the two collisions is extremely short. After repeated collisions, the foreign matter accumulated in the pipeline begins to break from the impact point and expand outward, eventually achieving the dredging of the pipeline; at the same time, during the dredging process, if the dredging rod 100 is inserted into the foreign matter and is stuck by the foreign matter, the striking sleeve 200 is slid in the reverse direction, so that the retracting surface 202 of the striking sleeve 200 collides with the receiving surface 106 of the dredging rod 100, and an outward pulling impact is applied to the dredging rod 100, helping the dredging rod 100 to be pulled out quickly.

[0039] Furthermore, a resistance surface capable of contacting the striking surface 105 and the receiving surface 106 is provided inside the striking sleeve 200; wherein, the resistance surface capable of contacting the striking surface 105 of the striking sleeve 200 is the striking surface 201; and the resistance surface capable of contacting the receiving surface 106 of the striking sleeve 200 is the retreat surface 202.
