[0049] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] In the related art, a water-cooled wall cleaning device is usually used to clean and maintain the water-cooled wall. The water-cooled wall cleaning device has a support beam extending in the horizontal direction. Due to the long length of the support beam, the strength of the support beam in the load-bearing direction and the direction perpendicular to the water-cooled wall is not high, there are potential safety hazards, and it affects the service life of the guide rail.

[0051] To solve the problems described in the related art, an embodiment of the present application provides a water-cooled wall cleaning device. The water-cooled wall cleaning device includes a support beam, a lifting mechanism, and a cleaning mechanism. The support beam includes a plurality of profiles and a plurality of guide rails arranged side by side. The lifting mechanism is installed on the profiles, and the cleaning mechanism is installed on the guide rails. Connecting members are provided between adjacent profiles and adjacent guide rails. In the extending direction of the guide rail, a reinforcing member is provided in the middle area of the guide rail, and the reinforcing member is connected to the guide rail and the profile. In the present disclosure, the support beam is composed of a plurality of profiles and a plurality of guide rails. Adjacent profiles and adjacent guide rails are formed through connecting members. Moreover, in the extending direction of the guide rail, a reinforcing member is provided in the middle area of the guide rail to form a connection with the profile through the reinforcing member, so that while the support beam has a modular design, the profile provides structural reinforcement for the guide rail in multiple directions, enhancing the structural strength of the support beam and improving the reliability of the water-cooled wall cleaning device.

[0052] According to an exemplary embodiment of the present application, as Figures 1 to 3 shown, a water-cooled wall cleaning device is provided. The water-cooled wall cleaning device is installed in a hydroelectric boiler and can clean the water-cooled wall on the inner wall of the hydroelectric boiler, facilitating subsequent maintenance to extend the service life of the water-cooled wall.

[0053] As Figure 1 shown, the water-cooled wall cleaning device includes a support beam 100 and a lifting mechanism 200. The support beam 100 is connected to the lifting mechanism 200, and the lifting mechanism 200 can drive the support beam 100 to move in the vertical direction to clean water-cooled walls at different heights. Exemplarily, the lifting mechanism 200, such as a driving motor, is connected to a chain, and the support beam 100 is arranged on a link of the chain. When the driving motor rotates, it drives the chain to drive the support beam 100 to rise or fall.

[0054] Referring to Figure 1 , the support beam 100 extends in the horizontal direction ( Figure 1 the x direction shown in

[0055] ), and the support beam 100 can be used to arrange the cleaning mechanism 300 to clean different areas of the water-cooled wall at the same horizontal height. As can be seen from the above, by providing the support beam 100 and the lifting mechanism 200, each area of the water-cooled wall can be cleaned. Figure 1 Among them, referring to

[0056] wherein, the support beam 100 includes a connected profile 10 and a guide rail 20. The cleaning mechanism 300 is installed on the guide rail 20. The profile 10 and the guide rail 20 are arranged side by side to enhance the anti-bending performance of the guide rail 20, that is, to enhance the load-bearing capacity of the guide rail 20. In some embodiments, the lifting mechanism 200 is installed on the profile 10, and the lifting mechanism 200 drives the profile 10 to move, thereby driving the guide rail 20 to move synchronously.Figure 1 , a cleaning mechanism 300 is provided on the guide rail 20, and the cleaning mechanism 300 can reciprocate along the extension direction of the guide rail 20 ( Figure 1 the x direction shown in the figure) to clean the water-cooled wall at different positions. In some alternative embodiments (not shown in the drawings), a plurality of cleaning mechanisms 300 are provided on the guide rail 20, and the plurality of cleaning mechanisms 300 are arranged at intervals along the extension direction of the guide rail 20, so that multiple positions on the water-cooled wall can be cleaned without moving the position of the cleaning mechanism 300 on the guide rail 20.

[0057] Among them, as Figure 1 shown, in the extension direction of the support beam 100 ( Figure 1 the x direction shown in the figure), a plurality of profiles 10 and guide rails 20 that make up the support beam 100 are provided. A connecting member 30 is provided between any two adjacent profiles 10, and a connecting structure is provided between any two adjacent guide rails 20. The connecting member 30 is used to connect adjacent profiles 10 and adjacent guide rails 20. In the water-cooled wall cleaning device provided in this embodiment, the support beam 100 is modularly designed for easy storage and transportation. While the connecting member 30 assembles and connects the guide rails 20, it can also connect the profiles 10 together, and the profiles 10 provide structural reinforcement for the guide rails 20. In addition, the modularly designed support beam 100 can have a wider application scenario. For example, according to the size of the water-cooled wall surface, an appropriate number of profiles 10 and guide rails 20 can be selected to assemble a support beam 100 with an appropriate length.

[0058] First of all, it should be noted that the connecting member 30 can only connect the end of the guide rail 20 to the profile 10. When the length of each section of the guide rail 20 is relatively long and the middle area of each section of the guide rail 20 has a cleaning structure, the middle area of the guide rail 20 may be deformed because it is not connected to the profile 10, which may cause adjacent guide rails 20 to be misaligned and affect the function of the support beam 100. Therefore, as Figure 1 shown, in the extension direction of the guide rail 20 ( Figure 1 the x direction shown in the figure), a reinforcing member 40 is provided in the middle area of the guide rail 20. The reinforcing member 40 is connected to the guide rail 20 and the profile 10, so that the middle area of the guide rail 20 is always connected to the profile 10, avoiding deformation of the guide rail 20 and keeping adjacent guide rails 20 aligned.

[0059] In the embodiment of the present disclosure, the support beam is composed of a plurality of profiles and a plurality of guide rails. Adjacent profiles and adjacent guide rails are formed by connecting members. Moreover, in the extension direction of the guide rail, a reinforcing member is provided in the middle area of the guide rail to form a connection with the profile through the reinforcing member. While the support beam has a modular design, the profile provides multi-directional structural reinforcement for the guide rail, enhancing the structural strength of the support beam and improving the reliability of the water-cooled wall cleaning device.

[0060] In an exemplary embodiment, as Figure 1 shown, this embodiment provides a water-cooled wall cleaning device. The water-cooled wall cleaning device includes a support beam 100, a lifting mechanism 200, and a cleaning mechanism 300. The support beam 100 includes a plurality of profiles 10 arranged side by side and a plurality of guide rails 20. The lifting mechanism 200 is installed on the profiles 10, and the cleaning mechanism 300 is installed on the guide rails 20. A connecting member 30 is provided between adjacent profiles 10 and adjacent guide rails 20. In the extending direction of the guide rail 20, a reinforcing member 40 is provided in the middle area of the guide rail 20, and the reinforcing member 40 is connected to the guide rail 20 and the profile 10.

[0061] In this embodiment, as Figure 1 shown, the guide rail 20 is located below the profile 10 ( Figure 1 the reverse of the y direction shown in ), and the cleaning mechanism 300 is arranged below the support beam 100 in a suspended manner. It can be understood that during the cleaning process, the lifting mechanism 200 will lift the support beam 100 to the top of the water-cooled wall, and then the cleaning mechanism 300 is activated to spray the cleaning liquid. Then, the lifting mechanism 200 drives the support beam 100 to gradually lower the height, that is, the water-cooled wall cleaning device performs cleaning in a moving direction from high to low, so as to avoid the impurities removed from the water-cooled wall falling on the water-cooled wall cleaning device.

[0062] Therefore, it can be determined that since the reinforcing member 40 is provided in the middle area of the guide rail 20,

[0063] Among them, as Figure 3 shown, an installation groove 21 is provided on one side of the guide rail 20. The installation groove 21 is U-shaped, and the inner wall of the installation groove 21 has a flange 22 protruding toward the inside of the groove. The connecting member 30 and the reinforcing member 40 can extend into the installation groove 21 and are snap-fitted with the flange 22. Refer to Figure 3 and Figure 4 , a part of the structures of the connecting member 30 and the reinforcing member 40 (the snap-fitting structure, which will be introduced in detail later) can extend between the flange 22 and the bottom surface of the installation groove 21, and the flange 22 can limit the connecting member 30 and the reinforcing member 40 from withdrawing from the installation groove 21 along the depth direction of the installation groove 21, thereby realizing snap-fitting.

[0064] In some embodiments, as Figure 4 shown, the connecting member 30 includes a first profile installation part 32 and a first guide rail installation part 33. The first guide rail installation part 33 is arranged on the same side of two connecting members 30, and the first profile installation part 32 is located on the side where two connecting members 30 are away from each other. Refer to Figure 4 , the first profile installation part 32 is located on the side where two connecting members 30 are away from each other. In the arrangement direction of two connecting members 30 ( Figure 4In the x-direction shown, adjacent profiles 10 are separately arranged on both sides of the connecting member 30 and are connected to the connecting member 30 through the first profile mounting portion 32. The shape of the first profile mounting portion 32 of the connecting member 30 can be similar to the shape of the profile 10. For example, if the cross-sectional contour of the profile 10 is rectangular, then the cross-sectional contour of the first profile mounting portion 32 can also be rectangular.

[0065] In one example, referring to Figure 3 and Figure 4 , each connecting member 30 can be connected to a guide rail 20 and a profile 10, so that two connecting members 30 can connect two guide rails 20 and two profiles 10 together, and the two guide rails 20 and the two profiles 10 are arranged side by side.

[0066] Among them, as Figure 4 and Figure 5 shown, the connecting member 30 includes a first main structure 31. The first guide rail mounting portion 33 includes a first clamping structure 331 and a first connecting structure 332. The first connecting structure 332 is used to connect the first main structure 31 and the first clamping structure 331 together.

[0067] In some embodiments, referring to Figure 4 , along Figure 4 the x-direction shown, the first clamping structure 331 and the first connecting structure 332 are in a T shape. Exemplarily, in Figure 4 the z-direction shown, the size of the first clamping structure 331 is larger than that of the first connecting structure 332. In the assembled state, the first clamping structure 331 can extend into the mounting groove 21 of the guide rail 20 and form a clamping connection with the mounting groove 21.

[0068] In some alternative embodiments, the first clamping structure 331 and the first connecting structure 332 can also be in the shape of a "dry" character, an L shape, etc., as long as it can be ensured that it can be clamped into the mounting groove 21.

[0069] Among them, as Figure 5 shown, a mounting groove 21 is provided on one side of the guide rail 20. The mounting groove 21 is U-shaped, and a flange 22 structure protruding toward the inside of the groove is provided on the side wall of the mounting groove 21. In the embodiments of the present disclosure, the shape and position of the flange 22 are not overly limited. For example, the flange 22 can be in the shape of a cuboid and is provided at the opening position of the mounting groove 21. In the assembled state, the first clamping structure 331 is located between the bottom surface of the mounting groove 21 and the flange 22, so that the flange 22 can limit the first clamping structure 331 from disengaging from the mounting groove 21 along the depth direction of the mounting groove 21, realizing a clamping connection. In some alternative embodiments, the sides of the flange 22 opposite to the first clamping structure 331 are rough surfaces (such as frosted surfaces) to prevent the guide rail 20 and the connecting member 30 from Figure 5The mutual movement in the x-direction shown in FIG. 1 improves the reliability of the assembly connection.

[0070] Continue reading Figure 4 The side wall of the connecting member 30 opposite to the first guide rail mounting portion 33 is provided with a first assembly hole 34, in which a fastener is arranged. In the assembled state, the fastener in the first assembly hole 34 can abut against the guide rail 20 to apply a force to the guide rail 20 away from the connecting member 30, thereby making the flange 22 of the guide rail 20 abut against the clamping structure of the connecting member 30 to form a reliable connection. It can be understood that the connecting member 30 can be made by an integral molding process such as casting and injection molding, without the need for a separate hole opening process. In this embodiment, a flange 22 is provided in the mounting groove 21 of the guide rail 20, and a second assembly hole 333 is provided on the connecting member 30, so that there is no need to open a hole in the guide rail 20 that can only be made through multiple processes, which reduces the difficulty of processing the guide rail 20 and avoids the reduction of the structural strength of the guide rail 20 caused by the opening of the hole.

[0071] This does not limit the technical solution of the present disclosure. In some optional implementations, a threaded assembly hole is provided on the guide rail 20, and the connecting member 30 can be connected to the guide rail 20 by fasteners such as screws.

[0072] Among them, Figure 4 As shown, the first guide rail mounting portion 33 is provided with a second assembly hole 333, the second assembly hole 333 is directly opposite to the first assembly hole 34, and the second assembly hole 333 exposes the bottom surface of the mounting groove 21. In the assembled state, the fasteners in the first assembly hole 34 and the second assembly hole 333 abut against the bottom surface of the mounting groove 21. In this embodiment, the guide rail 20 and the connecting member 30 have a tendency of relative displacement in the x direction. By providing the second assembly hole 333 on the first guide rail mounting portion 3330 close to the guide rail 20, the force arm of the fastener when subjected to torsion force is shortened, thereby improving the anti-bending performance of the fastener and improving the assembly reliability.

[0073] In other embodiments (not shown in the drawings), the second assembly hole is not provided on the first guide rail mounting portion, and the second assembly hole is staggered with the first guide rail mounting portion, so that the fastener in the second assembly hole can avoid the first guide rail mounting portion and connect to the guide rail.

[0074] At least one of the first assembly hole 34 and the second assembly hole 333 is a threaded hole, and the fasteners in the first assembly hole 34 and the second assembly hole 333 are bolts, and the bolts cooperate with the threaded holes. Figure 4, the second assembly hole 333 is a threaded hole, and the size of the first assembly hole 34 is larger than that of the second assembly hole 333. In another example (not shown in the drawings), the first assembly hole 34 is a threaded hole, and the size of the second assembly hole 333 is larger than that of the first assembly hole 34. In yet another example (not shown in the drawings), both the first assembly hole and the second assembly hole are threaded holes.

[0075] In some other embodiments, such as Figure 3 and Figure 6 shown, the reinforcing member 40 includes a second main structure 41 and a second guide rail mounting portion 42. The second guide rail mounting portion 42 includes a second clamping structure 421 and a second connecting structure 422. The second connecting structure 422 is used to connect the second main structure 41 and the second clamping structure 421. The second clamping structure 421 and the second connecting structure 422 are arranged in a T shape. In the assembled state, the second clamping structure 421 is located between the bottom surface of the mounting groove 21 and the flange 22, and the distance between the two flanges 22 on both sides of the mounting groove 21 is smaller than the size of the second clamping structure 421, so that the second guide rail mounting portion 42 is clamped in the mounting groove 21.

[0076] Such as Figure 6 and Figure 7 shown, the reinforcing member 40 further includes a third main structure 43. The third main structure 43 is arranged on the side of the profile 10 away from the guide rail 20, and the third main structure 43 and the second main structure 41 form a detachable connection. As Figure 7 shown, the second main structure 41 is in a "C" shape, the third main structure 43 is in an "I" shape, the third main structure 43 and the third main structure 43 enclose a "square" shape. The second main structure 41 surrounds three sides of the profile 10, and the third main structure 43 is located on the side of the profile 10 not surrounded by the second main structure 41, that is, the side of the profile 10 facing away from the guide rail 20. The detachable connection method is, for example, connected by fasteners such as bolts.

[0077] In one example, referring to Figure 7 , in Figure 1 in the x - direction shown, the depth of the "C" - shaped groove of the second main structure 41 ( Figure 1 in the y - direction shown) is smaller than the size of the profile 10, and the third main structure 43 gradually approaches the second main structure 41 to generate extrusion with the profile 10 to fix the profile 10.

[0078] It can be understood that the surface of the profile 10 is provided with a strip-shaped groove 11. The cross-section of the strip-shaped groove 11 is an inverted T shape. The head of the connecting bolt is arranged in the strip-shaped groove 11. The column body of the connecting bolt passes through the opening of the strip-shaped groove 11 and is connected to the connecting member 30. Since the connecting member 30 is arranged at the end of the profile 10, the connecting member 30 can be easily sleeved on the profile 10. The reinforcing member 40 is used to provide support for the middle area of the guide rail 20, so the reinforcing member 40 may also be located in the middle area of the profile 10. If the same structure as the connecting member 30 (i.e., providing the first profile installation part 32) is adopted, the assembly efficiency will be seriously affected. Therefore, the first profile installation part 32 is not provided in the reinforcing member 40 provided in the embodiments of the present disclosure. That is, the inner wall of the second main structure 41 of the reinforcing member 40 is a smooth surface. During assembly, the profile 10 can be inserted into the second main structure 41 along the opening direction of the "C" shape, and then the second main structure 41 and the third main structure 43 can be assembled together, with high assembly efficiency.

[0079] In some embodiments, as Figures 3 to 5 shown, the two connecting members 30 include a first member 30a and a second member 30b. A first protrusion 31a is arranged on the side of the first member 30a facing the second member 30b, and a first groove 31b is arranged on the side of the second member 30b facing the first member 30a. The first protrusion 31a is a frustum of a cone, and the size gradually decreases on the side close to the second member 30b. The first groove 31b matches the shape of the first protrusion 31a. In this embodiment, by providing the frustum-shaped first protrusion 31a and the first groove 31b that matches the shape of the first protrusion 31a, it is convenient to align the first member 30a and the second member 30b, and the installation efficiency is improved.

[0080] Among them, as Figures 3 to 5 shown, at least one second protrusion 32a is arranged on the side of the first member 30a facing the second member 30b, and at least a second groove is arranged on the side of the second member 30b facing the first member 30a. The second protrusion 32a is arranged on the radially outer side of the first protrusion 31a. The side of the second protrusion 32a facing the first protrusion 31a has a first surface, and the second groove is arranged on the radially outer side of the first groove 31b. The side of the second groove facing the first groove 31b is a first bottom surface. The first surface is flush with the first bottom surface. In this embodiment, by providing the second protrusion 32a and the second groove, when the second protrusion 32a abuts against the second groove, the first member 30a and the second member 30b can be aligned, so as to ensure the precise butt joint of the adjacent guide rails 20 on the same side of the connecting member 30, and the structural reliability of the support beam 100 is improved.

[0081] In an exemplary embodiment, as Figure 1As shown, this embodiment provides a water-cooled wall cleaning device, which includes a support beam 100, a lifting mechanism 200 and a cleaning mechanism 300. The support beam 100 includes a plurality of profiles 10 and a plurality of guide rails 20 arranged side by side. The lifting mechanism 200 is installed on the profile 10, and the cleaning mechanism 300 is installed on the guide rail 20. Connecting members 30 are provided between adjacent profiles 10 and adjacent guide rails 20. In the extension direction of the guide rail 20, a reinforcing member 40 is provided in the middle area of ​​the guide rail 20, and the reinforcing member 40 is connected to the guide rail 20 and the profile 10.

[0082] The water-cooled wall cleaning device provided in this embodiment may include any structure of the water-cooled wall cleaning device provided in the above embodiments.

[0083] In this embodiment, Figure 1 and Figure 2 As shown, the lifting mechanism 200 includes a roller module 201, and the roller module 201 has a magnetic module 204 to be magnetically connected to the water-cooled wall. By setting the magnetic module 204 in the roller module 201 to adsorb the water-cooled wall, it is ensured that there is a force between the support beam 100 and the water-cooled wall to approach each other, so as to avoid the cleaning mechanism 300 being subjected to a reaction force during cleaning, resulting in a reduction in the cleaning effect, thereby ensuring the cleaning effect.

[0084] See also Figure 2 The roller module 201 includes a wheel frame 202 and a roller 203 . The wheel frame 202 is connected to the profile 10 of the support beam 100 through a transition member, and the roller 203 is installed on the wheel frame 202 .

[0085] In one example, see Figure 2 , a magnetic module 204 is provided on the wheel frame 202, and the magnetic module 204 is used to provide a magnetic attraction force between the wheel frame 202 and the water-cooled wall. Among them, an adjustment mechanism is also provided on the wheel frame 202, one end of the adjustment mechanism is connected to the wheel frame 202, and the other end is connected to the magnetic module 204, and the adjustable direction of the adjustment mechanism is perpendicular to the water-cooled wall surface. The adjustment mechanism can adjust the distance between the magnetic module 204 and the water-cooled wall surface, thereby adjusting the magnetic attraction force between the magnetic module 204 and the water-cooled wall surface. The adjustment mechanism can be, for example, a screw slider mechanism, one end of the screw is rotatably connected to the wheel frame 202, the screw is threadedly matched with the slider, and the slider is connected to the magnetic module 204. The distance between the slider and the water-cooled wall surface can be adjusted by rotating the screw, thereby adjusting the distance between the magnetic module 204 and the water-cooled wall surface.

[0086] In another example (not shown in the drawings), the roller is a magnetic wheel.

[0087] Among them, Figure 1As shown, the lifting mechanism 200 includes a winch (not shown in the drawings) and a first towing rope 205. The first towing rope 205 is connected to the roller module 201 and is located above the support beam 100. The winch can wind up the first towing rope 205, thereby driving the support beam 100 to rise in height to clean a higher position of the water wall. The winch can also unwind the first towing rope 205, thereby driving the support beam 100 to lower in height to clean a lower position of the water wall.

[0088] Any two adjacent roller modules 201 share a first towing rope 205. In one example, refer to Figure 1 , in the extending direction of the support beam 100 ( Figure 1 the x direction shown in Figure 1 ), three roller modules 201 are provided. Taking the orientation shown in

[0089] as an example, the left roller module 201 and the middle roller module 201 share a first towing rope 205, and the right roller module 201 and the middle roller module 201 share a first towing rope 205.

[0089] In some alternative embodiments, the first towing rope 205 can be connected to the support beam 100. For example, a through hole can be opened in the profile 10 of the support beam 100, and the first towing rope 205 can be passed through the through hole in the profile 10.

[0090] Among them, as Figure 1 shown, the lifting mechanism 200 further includes a second towing rope 206. The second towing rope 206 is connected to the roller module 201 and is located below the support beam 100. During the operation, the first towing rope 205 and the second towing rope 206 simultaneously apply forces to the roller module 201, and the resultant force can make the roller module 201 fit more closely to the water wall. In addition, when the winch fails and cannot normally pull up or unwind the first towing rope 205, the support beam 100 can be pulled to the ground by applying a pulling force to the second towing rope 206.

[0091] In some embodiments, refer to Figure 8 and Figure 9 , a plurality of cleaning nozzles 302 are provided on the cleaning mechanism 300. The spraying direction of the cleaning nozzles 302 has a first preset angle with the extending direction of the support beam 100 ( Figure 1 the x direction shown in

[0092] It should be noted that some of the water-cooled walls in the thermal power boiler may be inclined. When the cleaning nozzle 302 sprays the cleaning liquid in the vertical direction, the cleaning nozzle 302 cannot effectively rinse the lower surface of the water-cooled wall, resulting in a poor cleaning effect. In one example, for instance, if the extension direction of the water-cooled wall forms a 45° angle with the vertical direction, then the first preset angle between the spraying direction of the cleaning nozzle 302 and the extension direction of the support beam 100 is 45°, and the second preset angle between the arrangement direction of the multiple cleaning nozzles 302 and the extension direction of the support beam 100 is 45°. In another example, for instance, if the extension direction of the water-cooled wall forms a 60° angle with the vertical direction, then the first preset angle between the spraying direction of the cleaning nozzle 302 and the extension direction of the support beam 100 is 30°, and the second preset angle between the arrangement direction of the multiple cleaning nozzles 302 and the extension direction of the support beam 100 is 60°.

[0093] Refer to Figure 9 , the cleaning mechanism 300 is provided with a gear structure 306 and a roller structure 305. A rack structure is provided on the guide rail 20 of the support beam 100. The roller structure 305 is arranged on the guide rail 20. The roller structure 305 can provide support for the cleaning mechanism 300. The gear structure 306 meshes with the rack structure, and the rotation of the gear structure 306 drives the cleaning mechanism 300 to move along the support beam 100.

[0094] Refer to Figure 8 and Figure 9 , the cleaning mechanism 300 is further provided with a first deflection structure 303. The nozzle support 301 provided with multiple nozzles is connected to the first deflection structure 303 and forms a rotational connection with the first deflection structure 303. When the nozzle support 301 rotates relative to the first deflection module, the orientation of the multiple cleaning nozzles 302 can be adjusted. For example, the spraying direction of the multiple cleaning nozzles 302 can be perpendicular to the water-cooled wall surface, or can form an angle with the water-cooled wall surface. Refer to Figure 9 , the cleaning mechanism 300 further includes a second deflection structure 304. The first deflection structure 303 is connected to the second deflection structure 304 and forms a rotational connection with the second deflection structure 304. When the first deflection structure 303 rotates relative to the second deflection structure 304, the distance between the cleaning nozzle 302 and the water-cooled wall can be adjusted.
