[0032] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.
[0033] The boiler water wall surface can have various impurities such as dust, slagging, coking, etc., and various cleaning brushes need to be used to achieve effective cleaning. The cleaning brushes in the related art need to be replaced multiple times during the cleaning process, and the cleaning efficiency is low and the cleaning effect is poor.
[0034] To solve the problems in the related art, the present application provides a cleaning device and a boiler water wall maintenance robot. The cleaning device includes a rotating roller and a plurality of bristle groups arranged on the rotating roller. The plurality of bristle groups are arranged along the circumferential direction of the rotating roller, and the bristle lengths of the plurality of bristle groups are different in the radial direction of the rotating roller. In the present application, the rotating roller is provided with a plurality of bristle groups with different lengths. When the rotating roller rotates, the plurality of bristle groups with different lengths can simultaneously clean the boiler water wall, the cleaning effect is good, and the time for replacing the bristles according to different impurities during cleaning can be saved, which is beneficial to improving the cleaning efficiency.
[0035] According to an exemplary embodiment of the present application, as Figure 1 and Figure 2As shown, the present embodiment provides a cleaning device 10, which is applied to a boiler water cooling wall maintenance robot, and which can remove the attached impurities by rotating to generate friction with the surface of the boiler water cooling wall, thereby facilitating the detection and maintenance of other functional devices on the boiler water cooling wall maintenance robot.
[0036] As shown in Figure 1 and Figure 2 , the cleaning device 10 includes a rotating roller 11 connected to the output shaft of a driving device 13 (a servo motor), and the output shaft of the driving motor outputs torque to drive the rotating roller 11 to rotate.
[0037] As shown in Figure 2 , the outer circumferential surface of the rotating roller 11 is provided with a plurality of bristle groups 12, which are arranged along the circumferential direction of the rotating roller 11, and the bristle lengths of the plurality of bristle groups 12 are different in the radial direction of the rotating roller.
[0038] In one example, referring to Figure 2 , the connecting frame 14 of the cleaning device 10 is fixedly connected to the robot body 20 of the boiler water cooling wall maintenance robot, and by adaptively setting the length dimension of the connecting frame 14 in the z direction in Figure 2 , the plurality of bristle groups 12 on the rotating roller 11 are all in contact with the boiler water cooling wall or the impurities on the boiler water cooling wall, so that cleaning is simultaneously performed by the plurality of bristle groups 12, the cleaning intensity is improved, and repeated switching of the bristles is not required, thereby saving cleaning time.
[0039] In another example (not shown in the drawings), the cleaning device is connected to the robot body of the boiler water cooling wall maintenance robot through an adjusting device. The adjusting device can adjust the relative position between the cleaning device and the robot body, thereby adjusting the distance between the rotating roller and the boiler water cooling wall, so that different bristle groups 12 can be in contact with the boiler water cooling wall and perform cleaning. For example, when the impurities attached to the boiler water cooling wall are less and the adhesion is low (such as dust), the adjusting device can adjust the rotating roller to have a larger distance from the boiler water cooling wall, so that the longest nylon bristles (to be described in detail below) are in contact with the boiler water cooling wall, thereby removing the impurities on the boiler water cooling wall. For example, when the impurities attached to the boiler water cooling wall are more and the adhesion is large (such as debris and floating coke), the adjusting device can adjust the rotating roller to have a smaller distance from the boiler water cooling wall, so that the shorter stainless steel bristles (to be described in detail below) are in contact with the boiler water cooling wall, thereby removing the impurities on the boiler water cooling wall.
[0040] In the embodiment, the rotating roller is provided with a plurality of brush groups with different lengths, and when the rotating roller rotates, the plurality of brush groups with different lengths can simultaneously clean the water-cooled wall of the boiler, the cleaning effect is good, and the time for replacing the brush according to different impurities during cleaning can be saved, which is beneficial to improving the cleaning efficiency.
[0041] In one example embodiment, as shown in Figure 1 and Figure 2 The embodiment provides a cleaning device 10 applied to a boiler water-cooled wall maintenance robot, the cleaning device 10 comprises a rotating roller 11 and a plurality of brush groups 12 provided on the rotating roller 11, the plurality of brush groups 12 are arranged along the circumferential direction of the rotating roller 11, and the brush lengths of the plurality of brush groups 12 are different in the radial direction of the rotating roller 11.
[0042] In the embodiment, as shown in Figure 3 The plurality of brush groups 12 comprise a first brush group 121, the first brush group 121 is made of a plurality of nylon brushes, one end of the nylon brush is connected with the rotating roller 11, and the other end of the nylon brush extends along the radial direction of the rotating roller 11. The first brush group 121 has the longest length in the plurality of brush groups 12. The nylon brush made of nylon has the advantages of softness, good shape recovery, high melting point, etc., and can effectively remove dust impurities attached to the boiler water-cooled wall.
[0043] As shown in Figure 3 The plurality of brush groups 12 comprise a second brush group 122, the second brush group 122 is made of a plurality of first stainless steel brushes, one end of the first stainless steel brush is connected with the rotating roller 11, and the other end of the first stainless steel brush extends along the radial direction of the rotating roller 11. The first stainless steel brush made of stainless steel has the advantages of high hardness and corrosion resistance, and can remove rust on the surface of the boiler water-cooled wall by scraping.
[0044] As shown in Figure 3 In the radial direction of the rotating roller 11, the length of the first stainless steel brush is less than the length of the nylon brush. It can be understood that the hardness of stainless steel is much higher than that of nylon, and when the first stainless steel brush and the nylon brush have the same deformation, the first stainless steel brush has stronger friction with the boiler water-cooled wall. Therefore, the length of the first stainless steel brush is set to be less than the length of the nylon brush, so that when the first stainless steel brush and the nylon brush are in contact with the boiler water-cooled wall, the first stainless steel brush only has a small deformation, avoiding that the first stainless steel brush has a large deformation to cause abrasion on the surface of the boiler water-cooled wall.
[0045] In some embodiments, the first stainless steel bristles are columnar in shape, and the plurality of columnar first stainless steel bristles form the tufted second bristle group 122. In other embodiments, the first stainless steel bristles are net-like in shape.
[0046] In one example embodiment, as shown in Figure 1 and Figure 2 The present embodiment provides a cleaning device 10 applied to a boiler water wall maintenance robot, the cleaning device 10 comprising a rotating roller 11 and a plurality of bristle groups 12 arranged on the rotating roller 11, the plurality of bristle groups 12 being arranged along the circumferential direction of the rotating roller 11, and the bristle lengths of the plurality of bristle groups 12 being different in the radial direction of the rotating roller 11.
[0047] The cleaning device 10 provided by the present embodiment can comprise the structure of the cleaning device 10 provided by each of the above embodiments.
[0048] In the present embodiment, as shown in Figure 4 and Figure 5 The plurality of bristle groups 12 comprise a third bristle group 123, the third bristle group 123 being composed of second stainless steel bristles 1231, the second stainless steel bristles 1231 being curved, and both ends of the second stainless steel bristles 1231 being connected to the rotating roller 11. The second stainless steel bristles 1231 are curved, and compared with the first stainless steel bristles extending in a straight line, the second stainless steel bristles 1231 have more structures contacting impurities (large cleaning area) in the case of the same number of first stainless steel bristles and second stainless steel bristles 1231, such as being able to remove molten state (such as boiler coking, also known as floating coking) impurities adhering to the boiler water wall by scraping.
[0049] Since the third bristle group 123 has stronger cleaning force than the first bristle group 121 and the second bristle group 122, the third bristle group 123 is the bristle group 12 with the smallest length among the plurality of bristle groups 12 in the radial direction of the rotating roller 11. Here, it should be noted that the plurality of bristle groups 12 can only comprise the first bristle group 121 and the third bristle group 123, or only comprise the second bristle group 122 and the third bristle group 123, or comprise the first bristle group 121, the second bristle group 122 and the third bristle group 123.
[0050] In the present embodiment, as shown in Figure 4 and Figure 5As shown, the third bristle group 123 further comprises a block-shaped brush head 1232, the second stainless steel bristle 1231 penetrates through a mounting hole arranged in the block-shaped brush head 1232, and the block-shaped brush head 1232 is located at the bending position of the second stainless steel bristle 1231. The block-shaped brush head 1232 is, for example, a stainless steel ball. In this embodiment, by arranging the block-shaped brush head 1232 in the third bristle group 123, the cleaning strength of the third bristle group 123 is further improved, which is beneficial to effectively removing the floating scale.
[0051] In some optional embodiments, referring to Figure 2 and Figure 3 , the plurality of bristle groups 12 further comprises a fourth bristle group 124, the fourth bristle group 124 comprises a third stainless steel bristle and a block-shaped brush head 1232, the first end of the third stainless steel bristle is connected with the rotating roller 11, the second end of the third stainless steel bristle extends along the radial direction of the rotating roller 11, and the block-shaped brush head 1232 is arranged at the second end of the third stainless steel bristle. It can be understood that the fourth bristle group 124 can have the same function as the third bristle group 123, and by arranging the block-shaped brush head 1232 on the bristle, the floating scale adhered to the boiler water wall can be effectively scraped off.
[0052] As shown in Figures 1 to 5 , the plurality of bristle groups 12 with different lengths are arranged alternately along the circumferential direction of the rotating roller 11. When the bristle groups 12 with the same length are arranged together for cleaning, the plurality of third bristle groups 123 will be in contact with the floating scale continuously, resulting in an increase in the load of the driving device 13. However, in the cleaning device 10 provided in the present application, the plurality of third bristle groups 123 are uniformly arranged on the outer circumferential surface of the rotating roller 11, which can reduce the load of the driving device 13 and is beneficial to prolonging the service life of the driving device 13. Moreover, when moving cleaning is performed, the bristles with various lengths can be in contact with the boiler water wall multiple times, which is high in cleaning efficiency and good in cleaning effect.
[0053] According to the exemplary embodiments of the present application, as shown in Figure 1 , the present embodiment provides a boiler water wall maintenance robot, which comprises a robot main body 20 and the cleaning device 10 provided in any of the preceding embodiments, the cleaning device 10 is mounted on the robot main body 20, the robot main body 20 can climb on the boiler water wall in a hanging or magnetic attraction manner, and then drives the cleaning device 10 to move to each position of the boiler water wall, so as to clean the entire boiler water wall.
[0054] The boiler water wall maintenance robot has all the features and technical effects of the cleaning device 10, for example, the rotating roller 11 is provided with multiple brush groups 12 with different lengths, and when the rotating roller 11 rotates, multiple brush groups 12 with different lengths can simultaneously clean the boiler water wall, the cleaning effect is good, and the time for replacing the brush according to different impurities during cleaning can be saved, and the cleaning efficiency is improved.

It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.
[0056] It should be understood that the application is not limited to the precise construction that has been described above and shown in the accompanying drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application is limited only by the appended claims.
