[0042] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] Please see Figures 1 to 13 The present invention preferably provides a technical solution: a boiler internal attachment cleaning device, comprising: a base, and several sets of floating adjustment brackets connected to the base; each set of floating adjustment brackets is equipped with a movable wheel, the movable wheel including a stator 217 and a rotor 2181 covering the outer wall of the stator 217, the outer wall of the rotor 2181 being fitted with a wheel body 213; and a magnetizing component disposed at the bottom of the stator 217; a forward pedal assembly in a ring array is disposed on the wheel body 213, the forward pedal assembly generating magnetism and adsorbing onto the inner wall of the boiler when it passes the magnetizing component; when the movable wheel passes over an uneven boiler wall, the floating adjustment brackets can drive the movable wheel to rise or fall; and a crushing blade assembly disposed at both ends of the base in the forward direction, the crushing blade assembly vibrating at high speed to cut the attachments on the inner wall of the boiler; and a cleaning component disposed in the middle of the base for cleaning and sucking up waste debris;

[0045] Furthermore, the stator 217 has a first coil 2171 distributed in a ring on its outer wall, and an iron core 218 distributed in a ring on the rotor 2181. When the first coils 2171 are energized, the first coils 2171 and the iron core 218 work together to drive the wheel body 213 where the rotor 2181 is located to rotate.

[0046] In this application, since the boiler is made of iron and other materials, a floating adjustment bracket and a moving wheel are set up. In the design of the moving wheel, a forward pedal assembly and a magnetization assembly are used. In the area where the forward pedal assembly contacts the inner wall of the boiler, the magnetization assembly makes the forward pedal assembly magnetic. It loses its magnetism in the area away from the inner wall of the boiler. This design not only facilitates the magnetic movement of the machine body inside the boiler, but also saves energy consumption.

[0047] With the further action of the floating adjustment bracket, the wheel body can be adjusted to tilt and lift or lower, such as... Figure 1 , 2 As shown, it can be applied to the uneven surface inside the boiler. The moving wheels can float up and down, and when it encounters a vertical surface, the floating adjustment bracket deflects and lifts in its forward direction, continuing to move upward along the wall, realizing free movement on the inner wall of the boiler, increasing its cleaning range and reaching various cleaning corners and positions. Preferably, the machine is equipped with a battery, which can be controlled by remote control to clean different positions inside the boiler.

[0048] Furthermore, the base includes an upper mounting base 111 and a lower mounting base 114 mounted on the lower part of the upper mounting base 111. Each set of floating adjustment brackets has two brackets arranged opposite each other on both sides of the base. The floating adjustment bracket includes a support leg 315, which is arc-shaped. A stator 217 is fixed on the side wall of the support leg 315. A first mounting shaft 3121 is laterally connected to the top side wall of the support leg 315. A second transmission gear 312 is fixed on the outer wall of the first mounting shaft 3121. An assembly groove 116 is provided on the lower mounting base 114 for the assembly insertion of the first mounting shaft 3121. The base also includes a mounting hole 115 opened on the lower mounting base 114. A first motor 320 is installed in the mounting hole 115. The output shaft of the first motor 320 is connected to the first transmission gear 311. The first transmission gear 311 meshes with the second transmission gear 312 to drive the support leg 315 to swing up and down.

[0049] Through the design of the floating adjustment bracket, such as Figure 2 , 3As shown, when the two first motors 320 arranged opposite each other are working, they can drive the first transmission gear 311 to rotate. Under the meshing action of the first transmission gear 311 and the second transmission gear 312, the support leg 315 where the first mounting shaft 3121 is located can swing, thereby causing the two moving wheels arranged opposite each other to move. Under its structure, two sets of implementation methods can be extended. In one implementation method, by floating the moving wheels up and down, it can be applied to the uneven surface inside the boiler. In another implementation method, when there is a vertical surface in front, the floating adjustment bracket deflects and lifts in its forward direction, and continues to move upward along the wall. Under the magnetic attraction of the moving wheels, the position of different surface positions can be moved.

[0050] Example 2

[0051] In another embodiment of the present invention, the forward pedal assembly includes a mounting frame 212 that is detachably mounted to the wheel body 213. A spring piece 220 is mounted at the bottom of the mounting frame 212, and a support plate 221 is connected to the top of the spring piece 220 and moves up and down inside the mounting frame 212. A second coil 222 is provided on the top of the support plate 221. The top of the second coil 222 extends to the outer wall of the pedal body 211 and is fixed to the pedal body 211.

[0052] Furthermore, the magnetization assembly includes a mounting plate 216 fixed to the bottom of the stator 217. The lower surface of the mounting plate 216 is provided with a second electrode 215 and a first electrode 214 provided at the proximal end of each mounting frame 212. When each mounting frame 212 is rotated to be below the mounting plate 216 and the second electrode 215 contacts the first electrode 214, current can be passed through the second coil 222 on the corresponding forward pedal assembly, thereby causing the pedal body 211 to generate magnetism.

[0053] In this embodiment, a forward pedal assembly and a magnetization assembly are provided, such as Figure 3 , 6 As shown in Figure 7, firstly, as Figure 7 As shown, under the action of the spring piece 220, the pedal body 211 can float within the mounting frame 212, which can further adapt to the unevenness of the boiler inner wall, such as... Figure 13Under the combined action of the stator 217 and the rotor 2181, the wheel body 213 can be driven to rotate as a whole. This causes the first electrode 214, which is set inside the mounting frame 212, to pass sequentially through the position of the second electrode 215, where the mounting plate 216 is located. After the first electrode 214 and the second electrode 215 come into contact, the second coil 222 inside the mounting frame 212 at the corresponding position is energized, which makes the pedal body 211 magnetic. When the first electrode 214 and the second electrode 215 are separated, the second coil 222 loses the current and the magnetic force disappears. The bottom of the wheel body, that is, the area in contact with the boiler, is magnetic and can be attracted to the surface of the inner wall of the boiler.

[0054] Example 3

[0055] In another embodiment of the present invention, the crusher assembly includes a support frame 411, which is mounted in a mounting groove 117 on a lower mounting base 114 via a mounting shaft; a third transmission wheel 413 fixed to both ends of the mounting shaft on the support frame 411; a second motor 460 embedded in the lower mounting base 114; a fourth transmission wheel 461 meshing with the third transmission wheel 413 fixed to the output shaft of the second motor 460; and a horizontal plate 421 disposed at the end of the support frame 411 away from the third transmission wheel 413. A plurality of rotatable shafts 424 are mounted on the horizontal plate 421, and an inclined cutting blade 422 is connected to the bottom of each shaft 424. A vibration motor 417 disposed on the support frame 411 is used to drive the support frame 411 and the plurality of cutting blades 422 at the end to vibrate and strike and cut the deposits on the inner wall of the boiler.

[0056] In this embodiment, a method for cleaning dirt adhering to the boiler wall is provided, which employs a crusher assembly, such as... Figure 3 , 9 As shown, the second motor 460, when in operation, drives the fourth transmission wheel 461 to mesh with the third transmission wheel 413, thereby causing the support frame 411 to deflect and lift upwards. When the device moves, the crushing blade assemblies on both sides are raised. After reaching the area to be cleaned, the crushing blade assemblies on both sides are driven to fall. By controlling the vibration motor 417, the cutting blades 422 on the horizontal plate 421 can move. The support frame 411 vibrates at high speed, causing the cutting blades 422 to crush the material. When the vibration motor 417 on the support frame 411 runs at high speed, it generates an up-and-down vibration, which in turn causes the entire support frame 411, along with the cutting blades 422 on the horizontal plate 421, to undergo impact-type crushing and cutting. Adjusting the power of the vibration motor 417 changes the intensity and amplitude of the vibration. The cutting blades 422 act on the surface of the boiler, causing the dirt to be broken up. This is the preferred crushing method, allowing the device to move back and forth within the cleaning area.

[0057] Furthermore, a one-way ratchet assembly mounted on the support frame 411 is used to drive the cutting blade 422 to rotate unidirectionally in stages to increase the cutting and breaking area. The one-way ratchet assembly includes a first crossbar 426, a second crossbar 427, and a ratchet body 423 fixed to the outer wall of each rotating shaft 424. The first crossbar 426 is fixed to the upper surface of the cross plate 421, and several anti-reverse springs 425 adapted to the ratchet body 423 are connected to the side wall of the first crossbar 426. The second crossbar 426... 27 is disposed on the opposite side of the first horizontal bar 426 and slidably mounted on the upper surface of the horizontal plate 421, and a plurality of ratchet blocks 428 adapted to the ratchet body 423 are provided on the side wall of the second horizontal bar 427. When the first horizontal bar 426 is pushed back and forth, under the combined action of the ratchet blocks 428 and the anti-reverse spring 425, the cutting blade 422 at the bottom of the rotating shaft 424 is driven to rotate gradually in one direction; and a transmission assembly mounted on the support frame 411 is used to push the second horizontal bar 427 to move.

[0058] Furthermore, the transmission assembly includes a horizontal shaft 414 eccentrically disposed between two ratchet bodies 423, a transmission component 415 connected in the middle of the horizontal shaft 414, and a long groove 416 formed on the support frame 411. The long groove 416 consists of a gentle section and a sloping section. A push rod 418 and a transmission rod 412 are respectively disposed inside the gentle section and the sloping section of the long groove 416. One end of the transmission rod 412 can abut against the push rod 418, and the other end is connected to the transmission component 415. An installation component 420 is assembled at the end of the support frame 411 near the horizontal plate 421. A sliding groove 4201 is provided on the installation component 420 for sliding installation of the push rod 418, and protrusions 4181 are provided on both sides of the push rod 418. A first spring piece 4182 is provided between the protrusions 4181 and the installation component 420 for resetting the push rod 418 after it is pushed.

[0059] Through the further configuration of the one-way ratchet assembly and the transmission assembly, such as Figure 3 , 8As shown in Figures 9 and 11, the support frame 411 is similar to two layers, with a transmission component set in the middle of the inner side. When the vibration motor 417 on the support frame 411 runs at high speed, it can generate an up-and-down vibration, which in turn drives the entire support frame 411 together with several cutting blades 422 on the horizontal plate 421 to perform impact-type crushing and cutting. At the same time, due to the action of the transmission component, the horizontal shaft 414 is eccentrically set relative to the third transmission wheel 413 and is not on the same axis as the third transmission wheel 413. When the support frame 411 and the transmission component 415 swing up and down together, the support frame 411 and the transmission component 415 will have relative displacement. The displacement difference will push the support frame 411 to move closer to the horizontal plate 421 and compress the first spring plate 4182. When the transmission rod 412 disengages from the end of the push rod 418, it will reset under the elastic force of the first spring plate 4182. The effect of this action is to convert the vibration of the support frame 411 into the back-and-forth movement of the second horizontal bar 427. This is further facilitated by the one-way ratchet assembly, combined with... Figure 8 , 9 As shown in Figure 10, when the second horizontal bar 427 drives the ratchet block 428 to move closer to the rotating shaft 424, the ratchet block 428 can cause the rotating shaft 424 where the ratchet body 423 is located to rotate step by step. Under the action of the anti-reverse spring 425 where the first horizontal bar 426 is located on the other side, it achieves unidirectional anti-reverse operation, thereby causing the cutting blades 422 where multiple rotating shafts 424 are located to rotate in one direction. As the cutting blades 422 rotate step by step as a whole, the local cutting and breaking area is covered more widely and the breaking is more thorough.

[0060] Example 4

[0061] In another embodiment of the present invention, the cleaning assembly includes a collection chamber 112, with a ring array of fans 113 arranged on the top of the collection chamber 112. Each fan 113 communicates with the inner cavity of the collection chamber 112 and provides negative pressure thereto. An extension cylinder 7152 is disposed in the middle of the collection chamber 112, with a certain distance between the top of the extension cylinder 7152 and the top of the inner cavity of the collection chamber 112. A splined groove 118 is provided in the middle of the lower mounting base 114, and a vertically movable mounting sleeve 713 is installed in the splined groove 118. A rotatable... The long straight cylinder 715 is movable, and a cleaning head 716 is connected to the bottom of the long straight cylinder 715. The cleaning head 716 has a dust suction chamber 718 inside, which is connected to the long straight cylinder 715. There are also several bristles 717 set at the bottom of the cleaning head 716. The top of the long straight cylinder 715 extends into the interior of the extension cylinder 7152 and is equipped with an impeller 7153. There is also a through groove 7151 on the peripheral wall of the long straight cylinder 715 below the impeller 7153. When the suction airflow passes through the impeller 7153 from bottom to top, it can drive the cleaning head 716 at the bottom of the long straight cylinder 715 to rotate as a whole.

[0062] In this embodiment, a cleaning component is further provided, such as... Figure 5 As shown, when the circumferentially distributed fans 113 are working, a strong negative pressure is generated. Dust and debris from the furnace wall enter through the dust suction chamber 718 opened in the cleaning head 716 and are collected from bottom to top into the collection chamber 112 by the long straight cylinder 715. Due to the limiting rotational installation of the long straight cylinder 715 and the mounting sleeve 713, and the matching impeller 7153, when the suction airflow comes out from the channel 7151, passes through the impeller 7153, and is discharged from the extension cylinder 7152, the impeller 7153 rotates under the action of the airflow, driving the entire cleaning head 716 below to rotate. At the same time, the bristles 717 complete the rotational cleaning, and the openings on both sides of the dust suction chamber 718 allow dust and debris to be sucked into it. Preferably, the device can move back and forth, and a filter device is provided at the bottom of the fan 113. The filter element can block dust and store it in the collection chamber 112.

[0063] Furthermore, a drive motor 711 is fixed to the bottom of the lower mounting base 114.
