[0037] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0039] Example 1

[0040] Referring to Figures 1 to 8, this is the first embodiment of the present application. This embodiment provides a heat pipe wall cleaning device, which includes a traveling unit 1, including a housing 11, a first motor 12 disposed on one side of the housing 11, and a transmission assembly 13 disposed inside the housing 11; a cleaning unit 2, including a scraping ring 21 and a traction column 22 disposed on the top of the scraping ring 21; the cleaning unit 2 is disposed at the bottom of the traveling unit 1 and is movably connected to the transmission assembly 13.

[0041] Furthermore, it also includes at least one pin 3.

[0042] Preferably, it also includes a support unit N, which includes a bracket N1 and a second lead screw N2 disposed inside the bracket N1; the bracket N1 includes at least one limiting plate N12 disposed inside it; the bracket N1 is shaped like a zigzag.

[0043] It should be noted that tubular air preheaters typically require cleaning two to three times a year. Inside the air preheater, several evenly arranged heat pipes (M) are usually installed for heat exchange. However, during long-term operation, dust accumulation and caking can easily occur.

[0044] Preferably, referring to Figures 1 and 8, the traveling unit 1 needs to be mounted on the support unit N. Specifically, the center of the threaded block 111 engages with the second lead screw N2. When the second lead screw N2 rotates, it can drive the traveling unit 1 to move laterally. The bracket N1 is Z-shaped, with a pair of symmetrically distributed support feet at its bottom for fixing to the support members on both sides of the heat pipe M or the inner wall of the air preheater. The two side walls of the bracket N1 can also be fixed to the support members of the heat pipe M or the inner wall of the air preheater by drilling bolt holes. Two symmetrically distributed limiting plates N12 are also fixed between the two side walls of the bracket N1. The limiting plates N12 can fit against the two side walls of the threaded block 111 to ensure that the traveling unit 1 will not flip over. The second lead screw N2 is also installed between the two limiting plates N12. The two ends of the second lead screw N2 completely penetrate the two side walls of the bracket N1, and a limiting ring is fixed at the rod body position of the second lead screw N2 end to prevent the second lead screw N2 from coming off the bracket N1 during operation. In addition, a second motor is fixed to one end of the second lead screw N2 for driving. The shaft end of the second motor is fixedly connected to the second lead screw N2, and the second motor can be fixed to the side wall of the bracket N1 by bolts or other means.

[0045] Preferably, the bottom of the traveling unit 1 is connected to a cleaning unit 2, which needs to be fitted onto each heat pipe M. The traveling unit 1 and the bracket N1 can be set in multiple groups according to actual needs. Each group can operate independently, or multiple traveling units 1 can be connected and driven in parallel to improve load capacity.

[0046] Preferably, the traveling unit 1 and the bracket N1 can be installed above, below, and on both sides of the heat pipe M group. Each cleaning unit 2 can also be driven longitudinally in parallel through the pin 3, and laterally in parallel through the eyeglass-shaped connecting piece. In addition, the cleaning unit 2 can also operate independently.

[0047] Example 2

[0048] Referring to Figures 1 to 8, this is the second embodiment of the present application, which differs from the first embodiment in that it further includes a threaded block 111 disposed on the top of the housing 11, a traction rod 112 disposed on the bottom of the housing 11, and a motor base 113 disposed on one side of the housing 11.

[0049] Furthermore, the transmission assembly 13 includes a rotating cylinder 131, a first lead screw 132 disposed inside the rotating cylinder 131, a deflection cylinder 133 disposed on one side of the first lead screw 132, a deflection rod 134 disposed through the outer walls of the rotating cylinder 131 and the deflection cylinder 133, and a spiral sleeve 135 disposed on the rod body of the first lead screw 132.

[0050] Furthermore, the transmission assembly 13 also includes a first L-shaped rod 136 disposed at the bottom of the rotating cylinder 131, and a second L-shaped rod 137 disposed at the bottom of the first L-shaped rod 136.

[0051] Furthermore, the rotating cylinder 131 includes a first connecting sleeve 1311 disposed on one side of its end face, and at least one movable port 1312 disposed on the other side of the rotating cylinder 131; the other end face of the rotating cylinder 131 is open in one direction; the first lead screw 132 includes adjusting columns 1321 disposed at both ends of it; the deflecting cylinder 133 includes at least one extension plate 1331 disposed on one side of its end face, a waist-shaped hole 1332 disposed in the middle of the extension plate 1331, a waist-shaped groove 1333 disposed on the inner wall of the waist-shaped hole 1332, and a second connecting sleeve 1334 disposed on the other end face of the deflecting cylinder 133; the spiral sleeve 135 includes at least one extension rod 1351 disposed on its outer wall, and a positioning ring 1352 disposed on the body of the extension rod 1351; the first lead screw 132 is threadedly engaged with the spiral sleeve 135.

[0052] Furthermore, the first L-shaped bar 136 includes a round bar 1361 disposed at its end;

[0053] The second L-shaped bar 137 includes a cylindrical hole 1371 disposed at one end thereof, and a spherical head 1372 disposed on the surface of the other end of the second L-shaped bar 137.

[0054] Furthermore, the scraping ring 21 includes multiple chip grooves 211 disposed on its inner wall, cutting blades 212 disposed on both end faces of the scraping ring 21, and at least one connecting seat 213 disposed on the side wall of the scraping ring 21.

[0055] The connector 213 includes a connector hole 2131 disposed therein.

[0056] Furthermore, the traction column 22 includes a sliding sleeve 221, an outwardly protruding column 222 disposed on the outer wall of the sliding sleeve 221, a spherical cavity 223 disposed inside the outwardly protruding column 222, and an open groove 224 disposed on one side of the spherical cavity 223.

[0057] The traction column 22 is fixedly connected to the outer wall of at least one scraping ring 21.

[0058] Furthermore, the pin 3 is disposed inside the connecting hole 2131.

[0059] It should be noted that, referring to Figure 2, the housing 11 is generally C-shaped with the opening facing downwards. A motor mount 113 is fixed to the outside of one of the side walls of the housing 11, and bolt posts are fixed to the motor mount 113. The first motor 12 is mounted on the motor mount 113, with its shaft end penetrating through the side wall of the housing 11. A threaded block 111 is also fixed to the top surface of the housing 11, which can cooperate with the support unit N. A traction rod 112 is also fixed at the opening of the housing 11, with both ends of the traction rod 112 fixedly connected to the two side walls of the housing 11.

[0060] Preferably, referring to Figures 3 and 4, the rotating cylinder 131 is semi-open, hollow inside, with an opening at one end and a first connecting sleeve 1311 fixed at the other end. The first connecting sleeve 1311 is fixedly connected to the shaft end of the first motor 12. When the first motor 12 runs, the rotating cylinder 131 rotates accordingly. In addition, at the opening of the rotating cylinder 131, a notch-shaped movable opening 1312 is provided on its outer wall. This movable opening 1312 can prevent interference caused by the movement of the deflecting cylinder 133.

[0061] Preferably, the opening of the rotating cylinder 131 can be provided with two symmetrically distributed movable openings 1312, which can ensure that the deflecting cylinder 133 can deflect in both directions.

[0062] Preferably, the first lead screw 132 is installed inside the rotating cylinder 131, and both ends of the first lead screw 132 completely penetrate the side wall of the rotating cylinder 131. To prevent the first lead screw 132 from detaching from the rotating cylinder 131, limit rings are fixed to both ends of the first lead screw 132. Adjusting pins 1321 are also fixed on the end face of the limit rings. There are two adjusting pins 1321, which are symmetrically distributed. Therefore, the first lead screw 132 can be rotated by twisting the adjusting pins 1321 using a power tool or a wrench or pliers.

[0063] Preferably, the deflecting cylinder 133 is hollow inside, closed on one side, and a second connecting sleeve 1334 is fixed on the other side. The second connecting sleeve 1334 is used to accommodate the first L-shaped rod 136. Two symmetrically distributed extension plates 1331 are also fixed on the closed end face of the deflecting cylinder 133, and the first lead screw 132 is located in the middle of the two extension plates 1331. An oblong hole 1332 is formed on the extension plate 1331, and an oblong groove 1333 is formed along the middle of the inner wall of the oblong hole 1332. The shape of the oblong groove 1333 is consistent with that of the oblong hole 1332.

[0064] 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.

[0065] 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, thus avoiding the extension rod 1351 from being dislodged from the extension plate 1331 due to the rotation of the spiral sleeve 135, or the spiral sleeve 135 being unable to be driven by the first lead screw 132 because it is not limited.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Preferably, referring to Figures 5 and 6, the scraping ring 21 has a slightly different shape depending on its position on the heat pipe M. 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.

[0071] Preferably, the scraping ring 21 is annular, and its inner wall has multiple staggered ash-removing grooves 211. When the scraping ring 21 moves on the heat pipe M, it can scrape off the accumulated dust on the heat pipe M through the ash-removing 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 smaller 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 ash-removing grooves 211. In order to ensure that multiple scraping rings 21 can work in parallel, two pairs of symmetrically distributed connecting seats 213 are also fixed on the outer wall of the scraping ring 21.

[0072] 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.

[0073] 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 positions of the first L-shaped rod 136 and the second L-shaped rod 137 will also change continuously, directly driving the scraping ring 21 to move along the traction rod 112.

[0074] 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.

[0075] During use, a different number of support units N need to be pre-installed according to the site conditions. Cleaning units 2 are installed on the support units N, and the cleaning units 2 are then fitted onto the heat pipes M. The cleaning units 2 are then installed in parallel to achieve horizontal / vertical linkage.

[0076] 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.

[0077] With the support unit N, it can be precisely moved to the area to be cleaned for targeted cleaning, and can also be thoroughly cleaned from start to finish.

[0078] In summary, compared to sawing and rinsing cleaning methods, this application provides a more comprehensive and thorough cleaning of the outer wall of heat pipe M. It can target different types of dust accumulation on heat pipe M for targeted cleaning, operate flexibly, and effectively balance work efficiency and cleaning capability. Furthermore, it can address complex dust accumulation situations through different connection methods.
