At the same time, the impeller 9 rotates to introduce water flow between the cleaning member 21 and the outer wall of the flue gas duct 1, and impacts the missed stubborn scale attached to the outer wall of the flue gas duct 1, thereby enhancing the cleaning effect and improving the cleaning efficiency.

The gear set 1 8 includes mutually meshing The gear set 2 14 includes a helical gear 3 and a helical gear 4 meshing with each other, one end of each of the two support frames 1 5 is fixedly connected to one end of the outer ring block 4, the stabilizing shell set 7 includes an elliptical block and an elliptical box with a hollow interior, two cross bars are fixedly connected between the elliptical block and one of the support frames 1 5, and between the elliptical box and the other support frame 1 5, the driving gear 6 is rotatably connected between the elliptical block and the elliptical box, the driving gear 6 and the shaft rod of the helical gear 2 both pass through the interior of the elliptical box and are connected to the same connecting belt for transmission, The other end of the shaft of the bevel gear 2 is rotatably connected to one end of the stabilizing shell group 7, one end of the bevel gear 1 is fixedly connected to the axis of one end of the runner 9, a number of lower grooves 2 with equal spacing and linear arrangement are provided on the outer walls of the flue gas ducts 1, the driving gear 6 is in meshing connection with the lower grooves 2, and the inner walls on both sides of the lower grooves 2 are provided with through grooves 3, one end of the horizontal rod 10 passes through the other end of the outer ring block 4 and is fixedly connected to the bevel gear 3, the bevel gear 4 is rotatably connected to the inner wall of the inner ring block 16, and the gear ring 20 is connected to the bevel gear The outer walls of the four wheels are meshed with each other, a zoom cavity 12 is opened at one end of the filling groove 11, and the other end of the outer annular block 4 is fixedly connected to a lower inclined plate 13, and the lower inclined plate 13 is located above the zoom cavity 12. The outer wall of the truncate block 18 is fixedly connected to four external blocks 25, and the outer wall of the passive block 17 is fixedly connected to four arc blocks 19. Each external block 25, arc block 19 and support frame 2 15 are arranged at equal intervals around the axis of the truncate block 18, and the arc block 19 is located between the truncate block 18 and the inner annular block 16.

[0033] It should be noted that: the present invention is based on the optimization and improvement of the comparative case in the background technology, so the scraper 40 in this article is observed in the appendix of the specification. Figure 4 The working principle is also consistent with the comparative document, and its specific working principle is not repeated here.

[0034] When the scraper 40 is displaced, it will drive each frustum-like block 18 to displace synchronously, and through each lower groove 2 opened, the driving gear 6 meshing therewith rotates. Under the connecting action of the connecting belt, the gear set 8 is driven, and the bevel gear 1 rotates and synchronously drives the runner 9 to rotate together. After the runner 9 rotates, it will suck the water flow in its vicinity into the inside of the injection groove 11, and then pass through the communicating scaling chamber 12, and finally flow into the passive block 17 and the flue gas duct 1. Through the provided scaling chamber 12 and the lower inclined plate 13, the scaling chamber 12 as a whole is composed of two grooves with trapezoidal cross sections. The ends of the two trapezoidal grooves with smaller cross-sectional areas are connected to each other. In the process of water flowing from the injection groove 11 into the scaling chamber 12, the cross-sectional area of ​​the water flow channel suddenly decreases, and then returns to normal. This will increase the impact force of the water flow. Under the obstruction of the lower inclined plate 13, the spraying direction of the water flow is more delicate. It will act directly between the cleaning piece 21 and the outer wall of the flue gas duct 1. Since the cleaning piece 21 is displaced while rotating, the water flow strengthened by the zoom chamber 12 will impact and clean the stubborn scale that may be attached to the outer wall of the flue gas duct 1 and has not been cleaned by the cleaning piece 21, thereby improving the cleaning effect. Through the set gear set 2 14 and gear ring 20, the rotation of the wheel 9 drives the horizontal rod 10 and the bevel gear three to rotate synchronously, and the bevel gear four rotates together with the bevel gear three, and the gear ring 20 meshing with the bevel gear four also rotates together, thereby driving the passive block 17 to rotate, and each cleaning piece 21 rotates around the axis of the flue gas duct 1 and cleans its outer wall in real time.

[0035] For example 3, please refer to Figures 1 to 11 On the basis of the second embodiment, the cross-section of the cleaning piece 21 is trapezoidal, a through rectangular through groove 22 is provided on one side of the cleaning piece 21, an elliptical plate 23 is rotatably connected between the inner walls on both sides of the rectangular through groove 22, and a plurality of rough soft pads 24 arranged linearly and at equal intervals are fixedly connected to the outer wall of the cleaning piece 21, and the plurality of rough soft pads 24 can all contact the outer wall of the flue gas duct 1.

[0036] By setting up each rough soft pad 24, the roughness of the contact end between the cleaning piece 21 and the outer wall of the flue gas duct 1 is increased, thereby improving the removal effect of stubborn scale. When each cleaning piece 21 rotates in a circle around the axis of the flue gas duct 1, each elliptical plate 23 will also rotate due to the resistance of water, thereby disturbing the water between the cleaning piece 21 and the outer wall of the flue gas duct 1, playing a role of flow disturbance here, and then self-cleaning the stubborn dirt accumulated between each rough soft pad 24, ensuring the cleaning effect of the rough soft pad 24, and the disturbed water flow can enter from one end of 3 and flow out from the other end, so as to perform self-cleaning treatment on 2.

[0037] Example 4, please refer to Figures 1 to 11On the basis of the third embodiment, one end of each external block 1 25 is fixedly connected to an external block 2 26, a through arc-shaped slot 27 is provided at the bottom end of the external block 26, the arc block 19 is in a sliding connection with the inner wall of the arc-shaped slot 27, an arc cavity 29 is provided inside the external block 26, an arc spring 30 is fixedly connected to the bottom end of the inner wall of the arc cavity 29, one end of the arc spring 30 is fixedly connected to an arc block 28, and the arc block 28 is slidably connected to the arc cavity 29. Inside the cavity 29, a part of the arc block 28 passes through the inside of the arc cavity 29 and is located inside the arc slot 27. The arc block 19 is in a movable connection with the arc block 28. A connecting plate 31 is fixedly connected to one side of the arc block 28. An arc slot is opened on one side of the external block 26. The arc slot is connected to the inside of the arc cavity 29. Four tooth block groups 33 are fixedly connected to the outer wall of the outer annular block 4. The four tooth block groups 33 are evenly spaced around the axis of the truncated cone block 18. The tooth block group 33 is arranged at a certain distance from each other, and each tooth block group 33 is meshed with a traveling gear 34. One end of the shaft of the traveling gear 34 is fixedly connected to one end of the connecting plate 31, and the other end of the traveling gear 34 is fixedly connected to a center block 35. The two ends of the shaft of 34 pass through the two 32 and are slidably connected to the inside of the two. Two stabilizing frames 32 that are far away from each other are fixedly connected to the outer wall of the outer annular block 4. The tooth block group 33 is located between the two stabilizing frames 32. The stabilizing frame 32, the connecting plate 31, and the external block 26 The arc-shaped block 28, the arc-shaped cavity 29 and the arc-shaped spring 30 are all located on the same circle, and the arc-shaped block 28, the arc-shaped cavity 29 and the arc-shaped spring 30 are located on another circle with a different center from the above circle. Four straight plates 1 36 are fixedly connected to the outer wall of the central block 35, which are equidistantly arranged around the axis of the central block 35 and are rotationally symmetrical. One end of each straight plate 1 36 is hinged to a straight plate 2, and one end of each straight plate 2 is fixedly connected to a soft hammer 37. The same elastic member 38 is fixedly connected between the straight plates 1 36 and the straight plates 2.

[0038] The interior of 32 is provided with a through groove for the arc-shaped sliding of the shaft 34. The rotation of the passive block 17 synchronously drives each arc block 19 to rotate. The arc block 19 will touch each arc block 28 during the rotation. Since the center of the circle to which the arc block 28 and the arc block 19 belong is not the same, the arc block 28 will retreat to the inside of the arc cavity 29 and compress the arc spring 30 after being impacted by the arc block 19. At the same time, the arc block 28 drives the connecting plate 31 to move together, and the travel gear 34 is displaced and rotated along the tooth block group 33, and the central block 35 is synchronously rotated and intermittently impacts the outer wall of the flue gas duct 1. Due to the mutuality of force, one end of the soft hammer 37 will rebound quickly after impacting the outer wall of the flue gas duct 1, and the elastic member 38 will bend and accumulate elastic force to enhance the next impact force. Under the high-frequency impact of each soft hammer 37, the probability of scale adhering to the outer wall of the flue gas duct 1 is reduced, and the stubborn scale that has been attached can be shaken to be peeled off, thereby further improving the cleaning effect of the scale.

[0039] In actual use, when the scraper 40 moves, it will drive each frustum-like block 18 to move synchronously. Under the action of the power connector 1 and the power connector 2, the impeller 9 rotates and sucks the water flow in its vicinity into the filling groove 11, and then passes through the communicating zoom chamber 12. After that, the impact force of the water flow increases, and acts directly between the cleaning piece 21 and the outer wall of the flue gas duct 1, and impacts and cleans the stubborn scale that may be attached to the outer wall of the flue gas duct 1 and has not been cleaned by the cleaning piece 21, thereby improving the cleaning effect. Each elliptical plate 23 will also rotate due to the resistance of the water, and then disturb the water between the cleaning piece 21 and the outer wall of the flue gas duct 1, playing a role of flow disturbance here, and then self-cleaning the stubborn dirt accumulated between each rough soft pad 24, ensuring the cleaning effect of the rough soft pad 24, and the rotation of the passive block 17 synchronously drives each arc block 19 to The arc block 1 19 will touch each arc block 2 28 during the rotation process. Since the center of the circle of the arc block 28 and the arc block 1 19 are not the same, the arc block 28 will retreat to the inside of the arc cavity 29 and compress the arc spring 30 after being impacted by the arc block 19. At the same time, the arc block 28 drives the connecting plate 31 to move together, and the traveling gear 34 moves and rotates along the tooth block group 33. The center block 35 rotates synchronously and intermittently impacts the outer wall of the flue gas duct 1. Due to the mutuality of force, one end of the soft hammer 37 will rebound quickly after impacting the outer wall of the flue gas duct 1, and the elastic member 38 will bend and accumulate elastic force to enhance the next impact force. Under the high-frequency impact of each soft hammer 37, the probability of scale adhering to the outer wall of the flue gas duct 1 is reduced, and the stubborn scale that has already attached can be shaken to peel it off, thereby further improving the cleaning effect of the scale.
