Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and particularly relates to a cleaning tooling and a wall cleaning device. Background Art

[0002] The water-cooled wall is usually composed of several rows of steel pipes, which is used to absorb the radiant heat of the high-temperature flame or flue gas in the furnace, generate steam or hot water in the pipe, thereby reducing the temperature of the furnace wall and protecting the furnace wall. It is the main heat-absorbing part in the boiler. With the extension of the operation time, after the surface of the water-cooled wall is contaminated, slagging and coking are likely to occur in the high-temperature environment, resulting in heat transfer loss.

[0035] To make the purposes, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. It should be noted that, without conflict, the embodiments in this application and the feature vectors in the embodiments can be combined with each other arbitrarily.

[0036] The water wall is usually composed of several rows of steel pipes, which is used to absorb the radiant heat of the high-temperature flame or flue gas in the furnace, generate steam or hot water in the pipes, thereby reducing the temperature of the furnace wall and protecting the furnace wall. It is the main heat-absorbing part in the boiler. As the operation time prolongs, after the surface of the water wall is contaminated, slagging and coking are likely to occur in the high-temperature environment, resulting in heat transfer losses. Therefore, during the actual operation of the boiler, it is necessary to clean the wall surface of the water wall in time to avoid economic losses and potential safety hazards.

[0037] Due to the relatively harsh working environment for water wall cleaning, in related technologies, a cleaning tooling is usually used to replace manual labor to flush the wall surface of the water wall. However, when the water wall has a certain inclination angle, the cleaning tooling usually cannot clean to the edge of the inclined wall surface, there are cleaning dead corners, and the wall surface positions that cannot be cleaned will also pose potential safety hazards due to dirt and slagging after long-term operation.

[0038] To solve the above problems, the present disclosure provides a cleaning tooling and a wall surface cleaning device. By setting the cleaning bracket to have an included angle with the second reference plane, the cleaning tooling is inclined at a certain angle to clean the wall surface, so that the entire wall surface can be cleaned, and a good cleaning effect can also be achieved on the inclined wall surface.

[0039] According to an exemplary embodiment, as Figures 1 - 6 shown, the embodiments of the present disclosure provide a cleaning tooling for cleaning the wall surface, such as cleaning the wall surface of the water wall of a boiler. The guide rail 10 is suspended on the water wall, and the cleaning tooling 20 is arranged on the guide rail 10. The guide rail 10 extends along the first direction (that is, Figures 1 - 6 the x-axis direction shown in Figures 1 - 6In the y-axis direction shown in [figure], the cleaning tooling 20 can move relative to the guide rail 10 in the first direction, so that the cleaning tooling 20 can clean the entire wall surface. Wherein, the plane determined by the first direction and the second direction is the first reference plane (that is, Figures 1 - 6 the xOy plane shown in [figure]), there is an inclined angle between the wall surface and the first reference plane, that is, the guide rail 10 and the wall surface are not parallel, but have a certain inclined angle, and the wall surface is an inclined wall surface relative to the guide rail 10.

[0040] Wherein, the cleaning tooling 20 includes a tooling main body 21, a connecting bracket 22, a cleaning bracket 23 and a cleaning part 24. The tooling main body 21 is movably connected to the guide rail 10, and the tooling main body 21 can move along the guide rail 10, so that the cleaning tooling 20 can move relative to the guide rail 10 in the first direction. One end of the connecting bracket 22 is fixedly connected to the tooling main body 21, and the other end of the connecting bracket 22 extends away from the guide rail 10 in the second direction. Wherein, the first reference plane is Figures 1 - 6 the xOy plane shown in [figure], the second direction is Figures 1 - 6 the y-axis direction shown in [figure], and the cleaning bracket 23 is arranged at the end of the connecting bracket 22 away from the guide rail 10.

[0041] Both ends of the cleaning bracket 23 are respectively connected to the connecting bracket 22, and there is a first preset angle between the line connecting the two ends of the cleaning bracket 23 and the second reference plane. The cleaning bracket 23 is used to install the cleaning part 24, and the cleaning part 24 is arranged on the side of the cleaning bracket 23 close to the wall surface, and the cleaning part 24 is used to clean the wall surface. Wherein, the second reference plane is perpendicular to the first reference plane and passes through the first direction. As Figures 1 - 6 shown, the first reference plane is the xOy plane, the first direction is the x-axis direction, and the second reference plane is the xOz plane. Since there is an inclined angle between the wall surface and the first reference plane, therefore, the cleaning bracket 23 is inclined, that is, the line connecting the two ends of the cleaning bracket 23 is set to have a first preset angle with the second reference plane, which can enable the cleaning part 24 to clean the edge of the wall surface when cleaning the wall surface. The magnitudes of the inclined angle and the first preset angle can be the same or different, and those skilled in the art can adjust according to actual needs, and the embodiments of the present disclosure do not limit this too much.

[0042] In the embodiments of the present disclosure, by setting the cleaning bracket to have an angle with the second reference plane, so that the cleaning tooling is inclined by a certain angle to clean the wall surface, thereby the entire wall surface can be cleaned, and a good cleaning effect can also be achieved on the inclined wall surface.

[0043] In some embodiments, taking Figure 1Taking the shown orientation as an example, the first direction is the horizontal direction and the second direction is the vertical direction. The guide rail 10 extends horizontally in the transverse direction, the cleaning tooling 20 moves horizontally on the guide rail 10, and the guide rail 10 can move vertically relative to the wall surface. Among them, the magnitudes of the first preset angle and the inclination angle are equal, so that when the cleaning tooling 20 cleans the inclined wall surface, it can clean to the edge of the wall surface, thereby cleaning the entire wall surface and avoiding cleaning dead corners.

[0044] In some embodiments, the connecting bracket 22 is provided with a first adjusting mechanism. The first adjusting mechanism is used to adjust the distance between at least one end of the cleaning bracket 23 and the guide rail 10 to adjust the magnitude of the first preset angle. In one example, one of the two ends of the cleaning bracket 23 is provided with the first adjusting mechanism, and the first adjusting mechanism is used to adjust the length of one end of the cleaning bracket 23 extending outside the connecting bracket 22, thereby adjusting the inclination degree of the cleaning bracket 23 relative to the second reference plane, that is, adjusting the magnitude of the first preset angle. In another example, the first adjusting mechanism is provided at both ends of the cleaning bracket 23, and the first adjusting mechanism is used to adjust the lengths of the two ends of the cleaning bracket 23 extending outside the connecting bracket 22 respectively, thereby adjusting the magnitude of the first preset angle between the line connecting the two ends of the cleaning bracket 23 and the second reference plane. The magnitude of the first preset angle can be adjusted according to the inclination angle between the wall surface and the first reference plane, for example, being equal to the inclination angle.

[0045] Among them, as Figures 2 - 6 shown, the first adjusting mechanism may include a first adjusting portion 221 provided on the connecting bracket 22 and a second adjusting portion (not shown in the figure) provided on the cleaning bracket 23. The second adjusting portion cooperates with the first adjusting portion 221. The first adjusting portion 221 may be a strip-shaped groove, and the second adjusting portion may be a limiting post that cooperates with the strip-shaped groove and can slide relative to the strip-shaped groove.

[0046] Of course, it can be understood that those skilled in the art can also set the first adjusting mechanism in other ways, such as using mechanical expansion, elastic expansion, etc., as long as the magnitude of the first preset angle can be adjusted. The specific setting method of the first adjusting mechanism in the embodiments of the present disclosure is not overly limited.

[0047] In some embodiments, the connecting bracket 22 is further provided with a second adjusting mechanism. As Figure 4As shown, the line connecting the two ends of the cleaning bracket 23 has a second preset angle with the first reference plane xOy. The second adjustment mechanism is used to adjust the height difference between the two ends of the cleaning bracket 23 to adjust the size of the second preset angle. By adjusting the second preset angle, the cleaning bracket 23 can be tilted relative to the first reference plane, thereby expanding the cleaning range of the cleaning part 24 on the wall surface in the first direction and improving the cleaning effect. The cleaning bracket 23 can be tilted to the left or right relative to the first reference plane, and the size of the second preset angle can be set to 0-30°, for example.

[0048] In one example, as Figure 4 shown, the second adjustment mechanism includes a third adjustment part 222 provided on the connecting bracket 22 and a fourth adjustment part provided on the cleaning bracket 23. The third adjustment part 222 and the fourth adjustment part are correspondingly arranged. The third adjustment part 222 and the fourth adjustment part can rotate relative to each other, and one of them is provided with a limit card slot, and the other of them is provided with a limit part corresponding to the limit card slot for rotation and limitation. The third adjustment part 222 can be provided only at one end of the connecting bracket 22, or for the consideration of improving the fixing stability, the third adjustment part 222 can be provided at both ends of the connecting bracket 22, and the third adjustment parts 222 at both ends of the connecting bracket 22 are centrosymmetric about the center of the connecting bracket 22.

[0049] Among them, the third adjustment part 222 can include a first arc-shaped groove, and the fourth limit part can include a first limit post (not shown in the figure) that cooperates with the first arc-shaped groove and can rotate relative to the first arc-shaped groove. The third adjustment part 222 can also include a plurality of limit holes provided in the first arc-shaped groove. When the first limit post rotates to different angles, it can cooperate and be clamped with different limit holes to fix the cleaning bracket 23 at the current size of the second preset angle. Of course, it can be understood that the third adjustment part 222 and the fourth limit part are not limited to the structures of the embodiments of the present disclosure, and those skilled in the art can also adjust the specific forms of the third adjustment part 222 and the fourth limit part according to actual needs as long as relative rotation between the two can be achieved.

[0050] In some embodiments, as Figure 5 shown, the cleaning part 24 includes at least one spray head 241. Among them, the spray head 241 is a high-pressure spray head that sprays high-pressure water flow onto the wall surface for cleaning, and there is a third preset angle between the spraying direction of the spray head 241 and the wall surface. The cleaning bracket 23 is also provided with a third adjustment mechanism for adjusting the orientation of the spray head 241 to adjust the size of the third preset angle.

[0051] Among them, in order to ensure the cleaning effect, the spraying direction of the spray head 241, that is, Figures 2 - 6The extending direction of the spraying surface 242 shown in [the figure] is generally approximately perpendicular to the wall surface. By adjusting the third preset angle between the spraying direction of the spray head 241 and the wall surface, the spraying angle of the spray head 241 can be adjusted. The range of the third preset angle can be, for example, 60° to 120°. By adjusting the third preset angle, the spray head 241 can clean the top and bottom of the wall surface. In addition, when cleaning, the spray head 241 is rotated back and forth to repeatedly wash the wall surface, which can also improve the cleaning effect of the spray head 241.

[0052] In one example, as Figure 3 shown, the cleaning bracket 23 includes a support portion 231 and a connecting portion 232 that can rotate relative to the support portion 231. Both ends of the connecting portion 232 are rotatably connected to the support portion 231, and the cleaning portion 24 is provided on the connecting portion 232. The third adjustment mechanism includes a fifth adjustment portion provided at both ends of the support portion 231 and a sixth adjustment portion provided at both ends of the connecting portion 232. The fifth adjustment portion can be set as a second arc-shaped groove 2311, and the sixth adjustment portion can be set as a second limiting post (not shown in the figure) that cooperates with the second arc-shaped groove 2311. When the connecting portion 232 rotates relative to the support portion 231, the second limiting portion can rotate and be limited in the second arc-shaped groove 2311.

[0053] In some embodiments, the cleaning portion 24 includes a plurality of spray heads 241. As Figure 5 shown, the plurality of spray heads 241 are evenly arranged on one side of the cleaning bracket 23 close to the wall surface, and the spraying ranges of two adjacent spray heads 241 at least partially overlap to avoid cleaning blind spots between the plurality of spray heads 241 and improve the cleaning effect.

[0054] In some embodiments, the cleaning tooling 20 further includes a water tank and / or a water supply pipeline (not shown in the figure). The water tank and / or the water supply pipeline are connected to the spray head 241, and water is supplied to the spray head 241 through the water tank of the cleaning tooling 20 itself and / or external water supply to perform high-pressure flushing and cleaning on the wall surface.

[0055] In some embodiments, as Figures 2 - 6 shown, the cleaning tooling 20 further includes a signal receiving device 25 and a control device (not shown in the figure). The signal receiving device 25 is electrically connected to the control device, and the control device is electrically connected to the first adjustment mechanism, the second adjustment mechanism, and the third adjustment mechanism respectively. The signal receiving device 25 is used to receive remote control instructions, and the control device controls the first adjustment mechanism, the second adjustment mechanism, and the third adjustment mechanism according to the remote control instructions to adjust the magnitudes of the first preset angle, the second preset angle, and the third preset angle.

[0056] Among them, the signal receiving device 25 may include an antenna, and the remote control instruction may be transmitted to the signal receiving device 25 in a wireless remote control manner such as an infrared signal, a Wi-Fi signal, etc. The signal receiving device 25 may be disposed at the top, bottom, side, etc. of the cleaning tooling 20. For example Figure 5 , Figure 6 As shown in, the signal receiving device 25 is disposed at the top and bottom of the cleaning tooling 20. Of course, it can be understood that the signal receiving device 25 may also be disposed at any other position that does not affect the normal operation of the cleaning tooling 20. The embodiments of the present disclosure do not impose too many restrictions on this, and those skilled in the art can select according to actual needs.

[0057] In some embodiments, such as Figure 4 , Figure 6 As shown in, the tooling main body 21 is provided with a first mating portion, and the guide rail 10 is provided with a second mating portion that mates with the first mating portion. Among them, one of the first mating portion and the second mating portion includes a sliding groove, and the other includes a sliding rail; and / or, one of the first mating portion and the second mating portion includes a gear, and the other includes a rack; and / or, one of the first mating portion and the second mating portion includes a guide wheel, and the other includes a guide groove.

[0058] In one example, such as Figure 4 , Figure 6 As shown in, the first mating portion includes a sliding groove 211, and the second mating portion includes a sliding rail (not shown in the figure). The sliding groove 211 cooperates with the sliding rail so that the tooling main body 21 can slide relative to the guide rail 10 in the first direction.

[0059] In another example, such as Figure 4 , Figure 6 As shown in, the first mating portion includes a gear 212, and the second mating portion includes a rack (not shown in the figure). Through the meshing transmission between the gear 212 and the rack, the tooling main body 21 can move relative to the guide rail 10 in the first direction.

[0060] In yet another example, such as Figure 4 , Figure 6 As shown in, the first mating portion includes a guide wheel 213, and the second mating portion includes a guide groove (not shown in the figure). The guide wheel 213 can roll in the guide groove so that the tooling main body 21 moves relative to the guide rail 10 in the first direction.

[0061] In still another example, such as Figure 4 , Figure 6As shown, the first mating part includes a sliding groove 211, a gear 212, and a guide wheel 213, and the second mating part includes a sliding rail, a rack, and a guide groove. The sliding groove 211 mates with the sliding rail, the gear 212 mates with the rack, and the guide wheel 213 mates with the guide groove. Through the combined action of multiple transmission methods, the smoothness of the relative movement between the tooling main body 21 and the guide rail 10 is improved. At the same time, when one of the transmission methods fails, normal transmission can still be ensured through other transmission methods, improving the reliability of the relative movement between the tooling main body 21 and the guide rail 10.

[0062] In some embodiments, the cleaning tooling 20 is further provided with a baffle 243. As Figures 2 - 6 shown, the baffle 243 is arranged on the cleaning bracket 23 to block the high-pressure water flow sprayed out by the spray head 241 and the dirt and impurities washed away, preventing them from splashing onto the tooling main body 21 and causing transmission failures or control malfunctions.

[0063] In some embodiments, the cleaning tooling 20 is further provided with an irradiation device 26. As Figures 2 - 5 shown, the irradiation device 26 can be arranged on the tooling main body 21 for irradiating the wall surface when the cleaning tooling 20 is operating, facilitating the observation of the cleaning situation and also facilitating the intuitive display and positioning of the operating position of the cleaning tooling 20.

[0064] According to an exemplary embodiment, as Figures 1 - 6 shown, the present disclosure embodiment provides a wall surface cleaning device for cleaning a water-cooled wall. The wall surface cleaning device includes a guide rail 10 suspended on the wall surface of the water-cooled wall, and a cleaning tooling 20 as described in the above embodiment arranged on the guide rail 10. The guide rail 10 extends in a first direction, and both ends of the guide rail 10 are connected to a magnetic adsorption wall-climbing device 30. The magnetic adsorption wall-climbing device 30 can generate an adsorption force with the wall surface of the water-cooled wall, so that the wall surface cleaning device is adsorbed on the wall surface of the water-cooled wall. At the same time, the magnetic adsorption wall-climbing device 30 can also move along a second direction on the wall surface, thereby driving the guide rail 10 to move relative to the wall surface along the second direction. The cleaning tooling 20 can move relative to the guide rail 10 along the first direction, so that the cleaning tooling 20 can clean the entire wall surface. Wherein, the plane determined by the first direction and the second direction together is a first reference plane, and there is an inclined angle between the wall surface and the first reference plane.

[0065] The cleaning tooling 20 includes a tooling main body 21, a connecting bracket 22, a cleaning bracket 23 and a cleaning part 24. The tooling main body 21 is movably connected to the guide rail 10, and the tooling main body 21 can move along the guide rail 10 so that the cleaning tooling 20 moves relative to the guide rail 10 in the first direction. One end of the connecting bracket 22 is fixedly connected to the tooling main body 21, and the other end of the connecting bracket 22 extends away from the guide rail 10 in the second direction. Both ends of the cleaning bracket 23 are respectively connected to the connecting bracket 22, and the line connecting both ends of the cleaning bracket 23 has a first preset angle with the second reference plane. The cleaning part 24 is arranged on the side of the cleaning bracket 23 close to the wall surface and is used to clean the wall surface. Wherein, the second reference plane is perpendicular to the first reference plane and passes through the first direction. The cleaning bracket 23 has a first preset angle with the second reference plane, so that the cleaning tooling is tilted at a certain angle to clean the wall surface, thereby being able to clean the entire wall surface.
