[0052] The second L-shaped rod 137 comprises a cylindrical hole 1371 arranged at the end thereof, and a spherical head 1372 arranged at the other end surface of the second L-shaped rod 137.

[0053] Further, the scraping ring 21 comprises a plurality of chip grooves 211 arranged at the inner wall thereof, cutting blades 212 arranged at both sides of the end face of the scraping ring 21, and at least one connecting seat 213 arranged at the side wall of the scraping ring 21;

[0054] The connecting seat 213 comprises a connecting hole 2131 arranged at the middle thereof.

[0055] Further, the traction column 22 comprises a sliding sleeve 221, an outer convex column 222 arranged at the outer wall of the sliding sleeve 221, a spherical cavity 223 arranged at the inner portion of the outer convex column 222, and an open groove 224 arranged at one side of the spherical cavity 223;

[0056] The traction column 22 is fixedly connected with the outer wall of at least one scraping ring 21.

[0057] Further, the pin rod 3 is arranged inside the connecting hole 2131.

[0058] It needs to be explained that referring to Fig. 2, the shell 11 is in the shape of C as a whole, the opening faces downward, and the motor seat 113 is fixed outside the sidewall in the shell 11, the bolt column is fixed on the motor seat 113, and the first motor 12 is installed on the motor seat 113, and the shaft end penetrates the sidewall of the shell 11. The threaded block 111 is also fixed on the surface of the top of the shell 11, which can cooperate with the supporting unit 4, and the traction rod 112 is also fixed at the opening of the shell 11, and the two ends of the traction rod 112 are fixedly connected with the two sidewalls of the shell 11.

[0059] Preferably, referring to Figs. 3 and 4, the rotating cylinder 131 is semi-open, hollow inside, one end of which is left with an opening, and the other end is fixed with the first connecting sleeve 1311, which is fixedly connected with the shaft end of the first motor 12, and when the first motor 12 operates, the rotating cylinder 131 also rotates correspondingly. In addition, the outer wall of the opening of the rotating cylinder 131 is provided with a notch-shaped movable opening 1312, which can avoid interference when the deflection cylinder 133 moves.

[0060] Preferably, the opening of the rotating cylinder 131 can be additionally provided with two symmetrically distributed movable openings 1312, which can ensure that the deflection cylinder 133 can be offset in two directions.

[0061] Preferably, the first lead screw 132 is installed inside the rotating cylinder 131, and the two ends of the first lead screw 132 completely penetrate the sidewall of the rotating cylinder 131, and the two ends of the first lead screw 132 are also fixed with the limiting ring to prevent the first lead screw 132 from separating from the rotating cylinder 131, and the adjusting column 1321 is also fixed on the end face of the limiting ring, and the number of the adjusting column 1321 is two and symmetrically distributed, so that the first lead screw 132 can be rotated by twisting the adjusting column 1321 through the electric tool or wrench.

[0062] Preferably, the deflection cylinder 133 is hollow inside, one side of which is closed, and the other side is fixed with the second connecting sleeve 1334, which is used to accommodate the first L-shaped rod 136. The two extension plates 1331 are symmetrically distributed and fixed on the end face of the closed side of the deflection cylinder 133, and the first lead screw 132 is located between the two extension plates 1331. The waist-shaped hole 1332 is opened on the extension plate 1331, and the waist-shaped groove 1333 is also opened along the inner wall of the waist-shaped hole 1332, and the shape of the waist-shaped groove 1333 is consistent with that of the waist-shaped hole 1332.

[0063] Preferably, a spiral sleeve 135 is also fitted onto the first lead screw 132. The spiral sleeve 135 is cylindrical, and its center is threaded into the first lead screw 132. Two symmetrically distributed extension rods 1351 are fixed on the outer wall of the spiral sleeve 135. The extension rods 1351 respectively enter the interior of the corresponding waist-shaped holes 1332, and the two are tangential to each other. A positioning ring 1352 is also fixed on the outer wall of the extension rods 1351. The positioning ring 1352 is precisely embedded in the waist-shaped groove 1333 and is tangential to the groove wall of the waist-shaped groove 1333, which can ensure that the two extension rods 1351 on the spiral sleeve 135 are perpendicular to the extension plate 1331.

[0064] Preferably, when the first lead screw 132 rotates, it can drag the spiral sleeve 135 to move along the axial direction of the first lead screw 132. Under the action of the waist-shaped groove 1333, the spiral sleeve 135 will not rotate, causing the extension rod 1351 to disengage from the extension plate 1331, or the spiral sleeve 135 cannot be driven by the first lead screw 132 because it is not limited.

[0065] Preferably, the deflecting rod 134 passes through both the deflecting cylinder 133 and the rotating cylinder 131. Limit rings are fixed to both ends of the deflecting rod 134 to prevent it from detaching from the rotating cylinder 131. The rotating cylinder 131 and the deflecting rod 134 can be fixedly connected or movably connected. Similarly, the deflecting cylinder 133 and the deflecting rod 134 can be fixedly connected or movably connected. It should be noted that a fixed connection of the deflecting rod 134 cannot occur simultaneously in both the deflecting cylinder 133 and the rotating cylinder 131, while a movable connection can occur simultaneously.

[0066] It should be noted that when the first lead screw 132 rotates, the screw sleeve 135 can drag the deflection cylinder 133 to deflect around the deflection rod 134. When there is only one movable port 1312, there is only one deflection direction. However, when there are two symmetrical movable ports 1312, there are two deflection directions, that is, bidirectional movement along the axis of the first lead screw 132. The movement in both directions has the same deflection effect.

[0067] Preferably, the first L-shaped rod 136 and the second L-shaped rod 137 are connected by a round rod 1361 and a cylindrical hole 1371. The upper end of the first L-shaped rod 136 can be inserted into the second connecting sleeve 1334. A limiting ring is also fixed at this end to prevent the first L-shaped rod 136 from coming out of the second connecting sleeve 1334. In addition, the end face of the limiting ring is tangent to the outer wall of the deflection rod 134 to further limit the first L-shaped rod 136. The other end of the first L-shaped rod 136 is fixed with a round rod 1361.

[0068] Preferably, the upper end of the second L-shaped rod 137 is provided with a cylindrical hole 1371, and the surface of the other end is fixed with a spherical head 1372, with the spherical head 1372 facing downward.

[0069] Preferably, referring to Figures 5 and 6, the scraping ring 21 has a slightly different shape depending on its position on the heat pipe 5. Since the scraping ring 21 at the outermost edge needs or may need to be connected to the traveling unit 1, a traction post 22 is also fixed on the outer wall of the scraping ring 21.

[0070] Preferably, the scraping ring 21 is annular, and its inner wall has multiple staggered shaving grooves 211. When the scraping ring 21 moves on the heat pipe 5, it can scrape off the accumulated dust on the heat pipe 5 through the shaving grooves 211. If there is finely clumped dust, it can be scraped repeatedly. A set of cutting blades 212 are also fixed at the openings on both sides of the scraping ring 21. The cutting blades 212 are evenly distributed around the circumference of the scraping ring 21. The cutting blades 212 facing the outer wall of the heat pipe and the direction of movement need to be sharpened. When large clumps of dust are found, they need to be cut into small pieces by the cutting blades 212 so that the clumps fall off on their own. The clumps that cannot fall off are then scraped repeatedly through the shaving grooves 211. In order to ensure that multiple scraping rings 21 can work in parallel, two pairs of connecting seats 213 are also fixed on the outer wall of the scraping ring 21.

[0071] Preferably, the traction post 22 is fixed to the outer wall of the scraping ring 21. Specifically, the outer wall of the sliding sleeve 221 is fixedly connected to the outer wall of the scraping ring 21. The sliding sleeve 221 is sleeved on the outer wall of the traction rod 112. An outward protruding post 222 is fixed at the upper end of the sliding sleeve 221. The upper end of the outward protruding post 222 is spherical, and a spherical cavity 223 is opened in the spherical end for cooperating with the spherical head 1372. An open groove 224 is opened at the upper end of the spherical cavity 223 to ensure that the second L-shaped rod 137 and the scraping ring 21 do not interfere with each other when they move relative to each other.

[0072] It should be noted that, referring to Figure 7, when the deflection cylinder 133 is driven to rotate, the different deflection angles directly affect the moving distance of the first L-shaped rod 136 and the second L-shaped rod 137. When the deflection angle approaches 0, the first L-shaped rod 136 and the second L-shaped rod 137 will remain in a vertical position, and the scraping ring 21 will not move at this time. When there is a deflection angle, the deflection cylinder 133 will drive the first L-shaped rod 136 and the second L-shaped rod 137 to rotate. At this time, the second L-shaped rod 137 is connected to the deflection cylinder 133, and the first L-shaped rod 136 and the second L-shaped rod 137 will swing. The position between the two rods will also change continuously, directly driving the scraping ring 21 to move along the traction rod 112.

[0073] In summary, the larger the deflection angle, the farther the scraping ring 21 moves and the smaller the transmitted torque; conversely, the smaller the deflection angle, the shorter the scraping ring 21 moves and the larger the transmitted torque.

[0074] During use, a different number of support units 4 need to be pre-installed according to the site conditions. Cleaning units 2 are installed on the support units 4, and the cleaning units 2 are then fitted onto the heat pipes 5. The cleaning units 2 are then installed side by side to achieve horizontal / vertical linkage.

[0075] When encountering ordinary dust accumulation, the first lead screw 132 can be adjusted to increase the deflection angle of the deflection cylinder 133, thereby expanding the cleaning distance of the dust removal device. When encountering smaller clumps, the first lead screw 132 can be adjusted to decrease the deflection angle of the deflection cylinder 133, thereby increasing the torque and improving the scraping ability. When encountering larger clumps, the deflection angle of the deflection cylinder 133 can be further reduced, and the number of connections of the cleaning unit 2 can be reduced to reduce the load and enhance the scraping ability.

[0076] With the support unit 4, it can be precisely moved to the area to be cleaned for targeted cleaning, and can also be thoroughly cleaned from beginning to end.

[0077] In summary, this design provides a more comprehensive and thorough cleaning of the outer wall of heat pipe 5 compared to sawing or rinsing methods. It can target different types of dust accumulation on heat pipe 5, operates flexibly, and effectively balances work efficiency and cleaning capability. Furthermore, it can handle complex dust accumulation situations through different connection methods.

[0078] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
