[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] In the present disclosure, unless otherwise specified, “inside and outside” refer to the inside and outside of the corresponding component outline; in addition, it should be noted that the terms used, such as “first, second”, etc., are used to distinguish one element from another.

[0045] According to one aspect of the present disclosure, Figure 1 As shown, a dust cleaning device 100 for a flue of a power plant is provided. The device may include a mounting base 1, a driving mechanism 2 and a scraping mechanism 3. The driving mechanism 2 is arranged on one side of the mounting base 1. The scraping mechanism 3 is arranged on the side of the mounting base 1 away from the driving mechanism 2. Among them, the scraping mechanism 3 may include an active member 31, a first follower 32 and a second follower 33. The driving shaft 21 of the driving mechanism 2 passes through the mounting base 1 and is connected to the active member 31. The first follower 32 and the second follower 33 are connected to the active member 31 at intervals along the circumference of the driving shaft 21. The first follower 32 and the second follower 33 are both used to contact the inner wall of the flue, and the active member 31 is used to drive the first follower 32 and the second follower 33 to rotate under the drive of the driving mechanism 2.

[0046] In the technical solution provided by the present disclosure, the driving shaft 21 of the driving mechanism 2 drives the active member 31 to rotate, and further, the active member 31 can drive the first driven member 32 and the second driven member 33 to rotate simultaneously, so as to achieve the purpose of cleaning the dust and sediment on the inner wall of the flue of the power plant. The dust cleaning device 100 provided by the present disclosure can realize automatic dust cleaning, with high dust cleaning efficiency, and effectively save labor costs.

[0047] In some embodiments, the drive mechanism 2 may use a motor as a driving member. Of course, the drive mechanism 2 may also use other suitable driving members to achieve the purpose of driving the active member 31 to rotate, which is not limited here, and those skilled in the art may design and select according to actual conditions. The motor is mainly used to take advantage of its high working efficiency and reliable operation.

[0048] In some embodiments, the first follower 32 and the second follower 33 may be arranged symmetrically about the axial direction of the drive shaft 21 to balance the forces on the drive members and increase their service life.

[0049] In some embodiments, Figure 1 andFigure 3 As shown, the soot cleaning device 100 may further include a first adjusting mechanism 4. The first adjusting mechanism 4 penetrates the driving member 31 in the axial direction perpendicular to the driving shaft 21. One end of the first adjusting mechanism 4 is connected to the first driven member 32, and the other end is connected to the second driven member 33. The first adjusting mechanism 4 is used to adjust the distance between the first driven member 32 and the driving member 31 and the distance between the second driven member 33 and the driving member 31. The setting of the first adjusting mechanism 4 enables the soot cleaning device 100 to be adjusted to a suitable position by the first adjusting device when it is arranged inside the power plant flue, so that the first driven member 32 and the second driven member 33 can reliably contact the inner wall surface of the flue to achieve the purpose of soot cleaning. The setting of the first adjusting mechanism 4 improves the use reliability and adaptability of the soot cleaning device 100. For example, it can be applied to flues of different sizes.

[0050] In a specific embodiment, as Figure 1 and Figure 3 shown, the first adjusting mechanism 4 may include a first adjusting screw 41, a first mounting sleeve 42, and a second mounting sleeve 43. The two ends of the first adjusting screw 41 are respectively provided with a first thread (not shown in the figure) and a second thread (not shown in the figure) with opposite helix directions. The inner wall of the first mounting sleeve 42 is provided with a third thread (not shown in the figure) with the same helix direction as the first thread. The inner wall of the second mounting sleeve 43 is provided with a fourth thread (not shown in the figure) with the same helix direction as the second thread. The first driven member 32 is connected to one end of the first adjusting screw 41 having the first thread through the first mounting sleeve 42, and the second driven member 33 is connected to the other end of the first adjusting screw 41 having the second thread through the second mounting sleeve 43. When the positions of the first driven member 32 and the second driven member 33 need to be adjusted, the first adjusting screw 41 can be rotated. Since the first thread and the second thread at both ends of the first adjusting screw 41 have opposite helix directions, when the first adjusting screw 41 rotates, the first driven member 32 connected to one end of the first adjusting screw 41 through the first mounting sleeve 42 and the second driven member 33 connected to the other end of the first adjusting screw 41 through the second mounting sleeve 43 will move synchronously in the direction of approaching or separating from each other, so as to achieve the purpose of adjusting the positions of the first driven member 32 and the second driven member 33 relative to the inner wall of the flue. This adjustment method is reliable, effective, low-cost, and easy to install.

[0051] Of course, it should be noted that the first adjusting mechanism 4 can also be realized in other ways, such as hydraulic telescopic rods, electric rods, gear racks, etc. There is no limitation here, and those skilled in the art can design according to the actual situation.

[0052] In some embodiments, as Figure 3As shown, the first adjustment mechanism 4 may further include a first gear 44, a drive rod 45 having a second gear 46, and a first mounting block 47 having a first mounting hole 471. The first gear 44 is sleeved outside the first adjustment screw 41. The first mounting block 47 is disposed on the driving member 31. The drive rod 45 is rotatably disposed through the first mounting hole 471 about its own axis. The second gear 46 meshes with the first gear 44. In use, the drive rod 45 rotates to cause the second gear 46 to rotate. The second gear 46 can drive the first gear 44 to rotate, and the rotation of the first gear 44 can drive the first adjustment screw 41 to rotate. The method provided in this embodiment for driving the first adjustment screw 41 to rotate is simple and reliable. Of course, it can be understood that the first adjustment screw 41 can also be driven to rotate by other suitable methods, which are not limited herein, and those skilled in the art can design and adjust according to the actual situation.

[0053] In some embodiments, as Figure 1 and Figure 3 shown, the dust cleaning device 100 may further include a positioning mechanism 5. The positioning mechanism 5 may include a first telescopic member 51 and a second telescopic member 52. Two ends of the first telescopic member 51 are respectively connected to the first driven member 32 and the driving member 31. Two ends of the second telescopic member 52 are respectively connected to the second driven member 33 and the driving member 31. The setting of the positioning mechanism 5 can prevent the first driven member 32 and the second driven member 33 from shaking after the position adjustment is realized through the first adjustment screw 41. The setting of the positioning mechanism 5 improves the reliability of use of the dust cleaning device 100. For example, the first telescopic member 51 and the second telescopic member 52 can be selected as telescopic rods, springs, etc., which are not limited herein, and those skilled in the art can design and adjust according to the actual situation.

[0054] In some embodiments, as Figure 1 and Figure 2 shown, a clamping mechanism 6 is further provided on one side of the mounting base 1. The clamping mechanism 6 includes a first clamping member 61 and a second clamping member 62. The first clamping member 61 and the second clamping member 62 are both movably connected to the mounting base 1 so as to be able to move closer to or away from each other. The setting of the clamping mechanism 6 facilitates the installation between the dust cleaning device 100 and the power plant flue. Further, the first clamping member 61 and the second clamping member 62 can move relative to the mounting base 1 to adapt to flues of different sizes, so as to improve the adaptability of the dust cleaning device 100. For example, the first clamping member 61 and the second clamping member 62 can be clamped on the outer wall of the flue and the ash scraping mechanism 3 can be extended into the flue for cleaning, or the first clamping member 61 and the second clamping member 62 can also be extended into the flue and respectively abut against the inner wall of the flue to realize the fixation relative to the flue. The specific use method can be adjusted according to the actual flue structure and scenario, and the present disclosure is not limited thereto.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, a mounting slot 11 is provided on the mounting base 1. The first clamping member 61 has a first mounting portion 611. The first mounting portion 611 is provided with a second mounting hole 611a. The second clamping member 62 has a second mounting portion 621. The second mounting portion 621 is provided with a third mounting hole 621a. Both the first mounting portion 611 and the second mounting portion 621 can slide through the mounting slot 11. The dust cleaning device 100 also includes a second adjustment mechanism 7. The second adjustment mechanism 7 includes a second adjustment screw 71. The two ends of the second adjustment screw 71 are respectively provided with a fifth thread (not shown in the figure) and a sixth thread (not shown in the figure) with opposite rotation directions. The inner wall of the second mounting hole 611a is provided with a seventh thread (not shown in the figure) consistent with the rotation direction of the fifth thread. The inner wall of the third mounting hole 621a is provided with an eighth thread (not shown in the figure) consistent with the rotation direction of the sixth thread. One end of the second adjustment screw 71 with the fifth thread is connected to the second mounting hole 611a. One end of the second adjustment screw 71 with the sixth thread is connected to the third mounting hole 621a. When the positions of the first clamping member 61 and the second clamping member 62 need to be adjusted, the second adjusting screw 71 can be rotated. Since the fifth thread and the sixth thread at both ends of the second adjusting screw 71 rotate in opposite directions, when the second adjusting screw 71 rotates, the first clamping member 61 connected to one end of the second adjusting screw 71 through the second mounting hole 611a and the second clamping member 62 connected to the other end of the second adjusting screw 71 through the third mounting hole 621a will move synchronously in the direction of approaching or moving away from each other, so as to achieve the purpose of adjusting the positions of the first clamping member 61 and the second clamping member 62 relative to the inner wall of the flue. This adjustment method is reliable, effective, low-cost and easy to install.

[0056] In some embodiments, Figure 2 As shown, the installation slot 11 may include a first slot body 111 and a second slot body 112. The first installation portion 611 of the first clamping member 61 may slidably pass through the first slot body 111. The second installation portion 621 of the second clamping member 62 may slidably pass through the second slot body 112. Dividing the installation slot 11 into the first slot body 111 and the second slot body 112 may limit the movement of the first clamping member 61 and the second clamping member 62.

[0057] In some embodiments, Figure 2 As shown, the clamping mechanism 6 further includes a second mounting block 12 having a sixth mounting hole 121. The second mounting block 12 is disposed on a side of the mounting base 1 away from the scraping mechanism 3. The second adjusting screw 71 is inserted into the sixth mounting hole 121. The provision of the second mounting block 12 improves the stability of the second adjusting screw 71 when it rotates.

[0058] In some embodiments, Figure 1 andFigure 2 As shown, on the side of the mounting base 1 facing away from the ash scraping mechanism 3, a receiving plate 13 is further provided. The driving mechanism 2 is arranged on the receiving plate 13. The provision of the receiving plate 13 provides a corresponding mounting position for the driving mechanism 2, making the structural layout of the entire ash cleaning device 100 more reasonable.

[0059] In some embodiments, as Figure 4 shown, the first follower 32 includes a first support portion 321 and a first moving portion 322. A third adjusting mechanism 8 is provided between the first support portion 321 and the first moving portion 322. The third adjusting mechanism 8 is used to adjust the position of the first moving portion 322 along the axial direction of the driving shaft 21 relative to the first support portion 321. And / or as Figure 6 shown, the second follower 33 includes a second support portion 331 and a second moving portion 332. A third adjusting mechanism 8 is provided between the second support portion 331 and the second moving portion 332. The third adjusting mechanism 8 is used to adjust the position of the second moving portion 332 along the axial direction of the driving shaft 21 relative to the second support portion 331. The provision of the third adjusting mechanism 8 enables the first follower 32 and the second follower 33 to move along the axial direction of the driving shaft 21 to adapt to the ash cleaning work of power plant flues with different depths. The provision of the third adjusting mechanism 8 improves the reliability and applicability of the ash cleaning device 100 in use.

[0060] In a specific embodiment, as Figure 4 shown, the third adjusting mechanism 8 may include a third adjusting screw 81. A fourth mounting hole 322a with a ninth thread is formed on the first moving portion 322, and the third adjusting screw 81 passes through the first support portion 321 and is threadedly connected to the fourth mounting hole 322a. And / or as Figure 5 shown, a fifth mounting hole 332a with a tenth thread is formed on the second moving portion 332, and the third adjusting screw 81 passes through the second support portion 331 and is threadedly connected to the fifth mounting hole 332a. When it is necessary to adjust the position of the first moving portion 322 relative to the first support portion 321, rotate the third adjusting screw 81, and the first moving portion 322 can be driven to move along the axial direction of the driving shaft 21. Correspondingly, when it is necessary to adjust the position of the second moving portion 332 relative to the second support portion 331, rotate the third adjusting screw 81, and the second moving portion 332 can be driven to move along the axial direction of the driving shaft 21. This adjustment method is reliable and simple. Of course, it can be understood that the third adjusting mechanism 8 can also be realized by other means such as slide rails and chutes, pulleys, etc., which are not limited herein, and those skilled in the art can design and adjust according to the actual situation.
