[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figure 1-Figure 7 As shown, the boiler cleaner according to the embodiment of the present invention comprises: a frame 1, a moving component 2, a flushing component 3 and a cleaning component 4.

[0036] The moving assembly 2 is connected to the frame 1, and the moving assembly 2 is moved along the height direction of the frame 1 (such as Figure 1 The flushing assembly 3 includes a water storage member 31 and a water spray member 32. The water storage member 31 is connected to the moving assembly 2, and the water spray member 32 is connected to the water storage member 31. There are multiple water spray members 32. The multiple water spray members 32 are arranged at intervals along the circumference of the center line of the frame 1, and the multiple water spray members 32 are movable in the up-down direction of the frame 1. The cleaning assembly 4 is connected to the moving assembly 2 and is located below the cleaning assembly 4. The cleaning assembly 4 includes a cleaning member 41. The cleaning member 41 is rotatable around the center line of the frame 1, and the cleaning member 41 is movable in the up-down direction of the frame 1.

[0037] Specifically, Figure 1-Figure 7 As shown, the moving assembly 2 is fixed to the frame 1 by welding or threaded connection, and the flushing assembly 3 is connected to a part of the moving assembly 2, so that the moving assembly 2 can drive the flushing assembly 3 to move in the up and down directions. The cleaning assembly 4 is arranged below the flushing assembly 3, so that the cleaning assembly 4 can scrape the dirt on the boiler wall and then use the flushing assembly 3 to perform flushing operations.

[0038] In some embodiments, the moving assembly 2 includes a moving drive member 21, and the output shaft of the moving drive member 21 is connected to the cleaning assembly 4 so as to drive the cleaning assembly 4 to move along the height direction of the frame 1. It can be understood that the moving drive member 21 can be a motor, and the output shaft of the moving drive member 21 can be connected to the flushing assembly 3 through a linear module, so that the output shaft of the moving drive member 21 rotates to drive the flushing assembly 3 and the cleaning assembly 4 to move in the up and down direction.

[0039] It is understandable that if Figure 1-Figure 7 As shown, the moving component 2 can be a device with a linear reciprocating function, such as a gear rack component, a linear module, etc., so as to drive the flushing component 3 and the cleaning component 4 to move in the up and down direction. Multiple water spraying components 32 can spray water toward the boiler wall, covering a wide range, and the reciprocating device can also be used to drive the water spraying components 32 to move up and down, so that the water spraying components 32 can spray water in different directions, thereby achieving flushing of different positions on the boiler wall. Similarly, the cleaning component 4 can also use a reciprocating device to scrape the boiler wall.

[0040] It should be noted that the water spraying member 32 may be a high-pressure nozzle, so that the water spraying member 32 can spray high-pressure water toward the boiler wall surface, thereby removing residual dirt on the boiler wall surface and improving the cleaning effect.

[0041] In other words, the boiler cleaner of the embodiment of the present invention can use the flushing component 3 and the cleaning component 4 to scrape and clean the dirt inside the boiler, and during the cleaning process, the flushing component 3 and the cleaning component 4 can also be used to clean the dirt in all directions to improve the cleaning effect.

[0042] In some embodiments, the flushing component 3 also includes a flushing drive 33 and multiple transmission components 34, the multiple transmission components 34 correspond one-to-one to the multiple water spray components 32, one transmission component 34 is connected to one water spray component 32, the flushing drive 33 is connected to the moving component 2, the transmission component 34 is rotatable around a first axial direction, and there is an angle between the axial direction of the transmission component 34 and the first axial direction, the first axial direction is parallel to the extension direction of the center line of the frame 1, the flushing drive 33 is connected to the transmission component 34 to drive the transmission component 34 to rotate, and the rotation of the transmission component 34 drives the water spray component 32 to move along the up and down direction of the frame 1.

[0043] Specifically, Figure 1 and Figure 2 As shown, the moving assembly 2 includes a moving frame 22, and a transmission member 34 is connected to the moving frame 22 through a transmission rod, and a gear is arranged on the transmission rod. The flushing drive member 33 can be a motor, and a gear transmission group is arranged between the output shaft of the flushing drive member 33 and the gear of the transmission rod, so that the output shaft of the flushing drive member 33 rotates, and the transmission rod can be driven to rotate through the gear transmission, and because the axial direction of the transmission member 34 has an angle with the first axial direction (that is, the transmission member 34 is arranged obliquely), the transmission member 34 drives the water spray member 32 to move in the up and down directions during the rotation process.

[0044] It is understandable that if Figure 1 and Figure 2As shown, since the transmission member 34 is arranged obliquely, the two ends of the rotating member are located at different high and low positions. When the transmission member 34 rotates, the two ends of the transmission member 34 can switch back and forth between the high and low positions, thereby driving the water spraying member 32 to move up and down, so as to flush a larger range of the boiler wall.

[0045] Optionally, the flushing assembly 3 further includes a diverter 35 and a connecting hose 36 , the diverter 35 is connected between the water spraying member 32 and the diverter 35 , and the connecting hose 36 is connected between the water spraying member 32 and the diverter 35 .

[0046] It is understandable that if Figure 1 and Figure 2 As shown, the diverter 35 has a water inlet and multiple water outlets. The water inlet can be connected to the water storage component 31 through a pipeline. The multiple water outlets correspond one-to-one to the multiple water spray components 32, and the water spray components 32, the connecting hose 36 and the water outlets are connected in sequence.

[0047] That is to say, the transmission member 34 drives the water spray member 32 to move during the rotation process. Since the water spray member 32 and the diverter 35 are connected by the connecting hose 36, the water spray member 32 can be easily moved, which not only ensures the water spraying effect but also reduces the friction between the water spray member 32 and the diverter 35.

[0048] In some embodiments, the flushing assembly 3 also includes a first connecting member 37, a first end of the first connecting member 37 is connected to the water spray member 32, a second end of the first connecting member 37 is connected to the transmission member 34, and an annular groove 341 is provided on one side of the transmission member 34 adjacent to the water spray member 32, and the second end of the first connecting member 37 is placed in the annular groove 341.

[0049] Specifically, Figure 1 , Figure 2 and Figure 6 As shown, the upper end of the first connecting member 37 is fixedly connected to the water spraying member 32 , and the lower end of the first connecting member 37 is fitted in the annular groove 341 , and the lower end of the first connecting member 37 is placed in the annular groove 341 and is movable relative to the transmission member 34 .

[0050] It is understandable that if Figure 1 , Figure 2 and Figure 6 As shown, the lower end of the first connecting member 37 and the annular groove 341 form a ball joint structure, so that the lower end of the first connecting member 37 can move in the annular groove 341, thereby driving the movement of the water spraying member 32. In other words, the transmission member 34 drives the water spraying member 32 to move through the first connecting member 37. When the first connecting member 37 is tilted in the front-to-back direction, the water spraying member 32 can move in the front-to-back direction, further expanding the water spraying range of the water spraying member 32 and improving the cleaning effect.

[0051] In some embodiments, the cleaning member 41 includes a connecting portion 411 and a scraping portion 412. The connecting portion 411 is connected to the flushing drive member 33 so that the flushing drive member 33 drives the connecting portion 411 to rotate. The scraping portion 412 is connected to the connecting portion 411 so that the rotation of the connecting portion 411 drives the scraping portion 412 to rotate.

[0052] Specifically, Figure 1-Figure 5 As shown, there are two scraping parts 412, and the two scraping parts 412 surround a circular ring structure, and the two scraping parts 412 are arranged at an interval so that the two scraping parts 412 can move relative to each other. The left and right ends of the connecting part 411 are respectively connected to the two scraping parts 412, and the middle part of the connecting part 411 is connected to the flushing driving member 33, so that the flushing driving member 33 drives the scraping parts 412 to rotate through the connecting part 411.

[0053] It is understandable that if Figure 1-Figure 5 As shown, the flushing drive member 33 can be a double-axle extension motor so as to provide the required power for the cleaning component 4 and the flushing component 3 at the same time. In addition, the connecting portion 411 can also be moved in the up and down directions by the moving component 2, so as to achieve the function of scraping the dirt on the boiler wall. Of course, other driving devices or structures can also be used to drive the connecting portion 411.

[0054] Optionally, the cleaning component 4 also includes a second connecting member 413 and a fixed rail 414, the fixed rail 414 is annular and connected to the movable component 2, the first end of the second connecting member 413 is connected to the scraping part 412, the second end of the second connecting member 413 is connected to the fixed rail 414, and the second connecting member 413 is movable in the extension direction of the fixed rail 414, and in a plane orthogonal to the height direction of the frame 1, the projection length of the fixed rail 414 is less than the extension length of the fixed rail 414.

[0055] Specifically, Figure 1 , Figure 3 and Figure 7 As shown, the fixed rail 414 is fixedly connected to the movable frame 22, the upper end of the second connecting member 413 is connected to the fixed rail 414 and can slide on the fixed rail 414, and the lower end of the second connecting member 413 is hinged to the connecting portion 411 so that the second connecting member 413 can rotate relative to the fixed rail 414.

[0056] It can be understood that, in a plane orthogonal to the up and down directions, the projected length of the fixed rail 414 is smaller than the extended length of the fixed rail 414, so that when the flushing drive 33 drives the connecting part 411 to rotate, the second connecting part 413 can slide on the fixed slide rail. Since the fixed slide rail has an undulating structure, the scraping part 412 can rotate around the output shaft of the flushing drive 33 while making reciprocating motion in the up and down directions, thereby ensuring the dirt removal effect of the cleaning component 4.

[0057] In some embodiments, the fixed rail 414 includes a plurality of undulating sections 4141 connected in sequence, the undulating section 4141 includes a smoothly connected protrusion 41411 and a recessed section 41412 , and in the height direction of the frame 1 , the protrusion 41411 is located above the recessed section 41412 .

[0058] Specifically, Figure 1 , Figure 3 and Figure 7 As shown, the undulating section 4141 is S-shaped, and a plurality of undulating sections 4141 are sequentially connected end to end to form a fixed track 414, so that when the second connecting member 413 moves along the fixed track 414, the connecting portion 411 is driven to reciprocate in the up and down directions.

[0059] In some embodiments, the cleaning member 41 further includes a scraper 415, which is detachably connected to the scraper portion 412, and the scraper 415 is located on the side of the scraper portion 412 adjacent to the boiler wall. It is understood that, as shown in the figure, the scraper 415 can be made of rubber material, and the scraper 415 is arc-shaped, and the scraper 415 is installed on the outside of the scraper portion 412, which not only facilitates the scraper 415 to contact with the boiler wall and ensure the scraping effect, but also allows the scraper 415 to be disassembled and installed after being used for a long time.

[0060] In some embodiments, the cleaning member 41 also includes a first locking member 416 and a second locking member 417. The first locking member 416 is connected to the scraping portion 412, and the second locking member 417 is connected to the scraping blade 415. The cleaning member 41 has a first locking state and a second locking state. In the first locking state, the first locking member 416 is connected to the second locking member 417 to prevent the scraping blade 415 from moving in a direction away from the scraping portion 412; in the second locking state, the first locking member 416 is separated from the second locking member 417 so that the scraping blade 415 can be removed from the scraping portion 412.

[0061] Specifically, Figure 1 , Figure 4 and Figure 5As shown, the second locking member 417 has a matching groove 418, the scraping portion 412 is provided with a first locking groove 4112 and a second locking groove 4113, the first locking member 416 is arranged in the first locking groove 4112, in the first locking state, the second locking member 417 is placed in the second locking groove 4113, and one end of the first locking member 416 is placed in the matching groove 418. An elastic member 419 is also provided in the first locking groove 4112, and the elastic member 419 is connected to the first locking member 416 and the bottom wall of the first locking groove 4112. The first locking member 416 has a protrusion 4161, the scraping portion 412 is provided with a sliding groove 4121 and a fixing hole 4111, the protrusion 4161 is placed in the sliding groove 4121, the sliding groove 4121 is communicated with the first locking groove 4112, and the fixing hole 4111 is communicated with the second locking groove 4113.

[0062] It can be understood that the protrusion 4161 is first moved in the sliding groove 4121 so that the protrusion 4161 drives one end of the first locking member 416 to be inserted into the matching groove 418, and then the bolt is threadedly connected to the fixing hole 4111 to fix the first locking member 416 and the second locking member 417, thereby realizing the installation of the scraper 415. At this time, the elastic member 419 is in a stretched state; conversely, when the scraper 415 needs to be replaced, the bolt connected to the fixing hole 4111 is loosened, and the first locking member 416 can be disengaged from the matching groove 418 under the elastic force of the elastic member 419, thereby the second locking member 417 can be pulled out from the second locking groove 4113, thereby realizing the removal operation of the scraper 415.
