[0032] 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.

[0033] like Figures 1 to 6 As shown, an embodiment of the present invention provides a thermal power plant boiler descaling device 100, which includes a mounting frame 10, an adjustment component 20 and a descaling component 30. The mounting frame 10 is installed on the boiler, and the mounting frame 10 has a first chute 11 and a second chute 12 that are connected, and the first chute 11 and the second chute 12 are cross-shaped and staggered and connected; the adjustment component 20 includes a support rod 21 and a slider 22, and the slider 22 is slidably arranged in the first chute 11 and the second chute 12, and the support rod 21 is connected to the slider 22, and the support rod 21 has a movable groove 21 1, the straight line where the extending direction of the moving groove 211 is located is arranged parallel to the plane where the mounting frame 10 is located; the descaling component 30 includes a sliding seat 31, a cleaning brush 32, a driver 33 and a telescopic rod 34, the sliding seat 31 is slidably arranged in the moving groove 211, the driver 33 is arranged on the sliding seat 31, one end of the telescopic rod 34 is connected to the output end of the driver 33, and the other end of the telescopic rod 34 is connected to the cleaning brush 32, the telescopic rod 34 is used to drive the cleaning brush 32 to reciprocate in a direction perpendicular to the plane where the mounting frame 10 is located, and the driver 33 is used to drive the cleaning brush 32 to rotate.

[0034] Specifically, the mounting frame 10 is the basic supporting structure of the entire device, which can be detachably mounted on the boiler, which is convenient and practical. The mounting frame 10 is integrated with a first slide groove 11 and a second slide groove 12 arranged in a cross shape, that is, the first slide groove 11 can be extended along the left and right direction of the boiler channel, and the second slide groove 12 can be extended along the front and back direction of the boiler channel, so that the adjustment component 20 drives the descaling component 30 to move in all directions in the boiler channel, thereby improving the scope of descaling and cleaning. In addition, the descaling component 30 can move along the moving groove 211 on the support rod 21, so that it can be adjusted synchronously with the first slide groove 11 and the second slide groove 12, further ensuring that the descaling operation can fully cover every area that needs to be cleaned.

[0035] In addition, the driver 33 can drive the cleaning brush 32 to rotate, using the principle of physical friction to effectively remove stubborn dirt on the inner wall of the boiler. The telescopic rod 34 can drive the cleaning brush 32 to reciprocate in the vertical direction, so that it can penetrate into every corner of the boiler channel and perform a full range of cleaning operations. This combination of reciprocating movement and rotation cleaning not only greatly improves the descaling efficiency, but also effectively reduces manual intervention, thereby improving the safety of the operation.

[0036] Furthermore, the straight line in which the moving groove 211 extends is always perpendicular to the straight line in which one of the first slide groove 11 and the second slide groove 12 extends. That is, when the slider 22 in the adjustment component 20 is located in the first slide groove 11, the straight line in which the moving groove 211 extends is perpendicular to the straight line in which the second slide groove 12 extends. Similarly, when the slider 22 in the adjustment component 20 is located in the second slide groove 12, the straight line in which the moving groove 211 extends is perpendicular to the straight line in which the first slide groove 11 extends, so as to improve the comprehensiveness and accuracy of the descaling operation.

[0037] In summary, the thermal power plant boiler descaling device 100 provided in the embodiment of the present invention, through the mutual cooperation of the first slide groove 11 and the second slide groove 12 arranged in a cross shape, the adjustment component 20 and the driver 33 and the telescopic rod 34 in the descaling component 30, not only significantly improves the descaling efficiency of the boiler channel, but also effectively ensures the safety of the operating personnel, and brings revolutionary changes to the daily operation and maintenance of the thermal power plant.

[0038] like Figure 1 As shown, in some embodiments, the boiler descaling device 100 of a thermal power plant further includes a plurality of clamping assemblies 40, wherein the clamping assemblies 40 include two clamping plates 41 arranged opposite to each other, and the mounting frame 10 is provided with a connecting groove 13 corresponding to the clamping plates 41, and the two clamping plates 41 can slide in the connecting groove 13 to clamp or release the boiler accordingly. Among them, the two clamping plates 41 arranged opposite to each other can move toward or away from each other to form a clamp-like structure, which can firmly clamp the outer wall surface of the boiler and ensure that the device can be firmly installed on the boiler. In addition, the connecting groove 13 provided on the mounting frame 10 can provide a stable sliding track for the clamping plates 41, ensuring the precise positioning of the clamping assembly 40 during the installation process, so that the staff can easily realize the operation of clamping or releasing the boiler, thereby greatly improving the installation convenience and flexibility of the device.

[0039] In addition, the multiple groups of clamping assemblies 40 can be arranged at an angle so that they can work together, so that the descaling device can be firmly attached to the boiler, and can maintain a stable operating state even when performing high-intensity descaling operations. In this embodiment, the clamping assemblies 40 are arranged in two groups, one of the two groups of clamping assemblies 40 is arranged along the left-right direction of the mounting frame 10, and the other of the two groups of clamping assemblies 40 is arranged along the front-back direction of the mounting frame 10.

[0040] Furthermore, the clamping assembly 40 also includes a screw rod 42, which is inserted into the connection groove 13, and the clamping plate 41 has a displacement seat 411, which is threadedly connected to the screw rod 42, and the displacement seat 411 is slidably arranged in the connection groove 13. In other words, when manipulating the clamping plate 41 to move toward or away from each other, the staff only needs to rotate the screw rod 42, and the displacement seat 411 is driven to slide in the connection groove 13 through the transmission effect of the thread, so as to achieve precise adjustment of the clamping plate 41. In addition, the clamping assembly 40 can also be adjusted according to the actual shape and size of the boiler to ensure a close fit between the descaling device and the boiler.

[0041] During use, the staff can adjust the position and clamping force of the clamping plate 41 by rotating the screw 42 according to the specific situation of the boiler. When the boiler needs to be clamped, it is only necessary to rotate the screw 42 so that the displacement seat 411 drives the clamping plate 41 to move toward the boiler until the clamping plate 41 firmly clamps the boiler; when the boiler needs to be loosened, the screw 42 is rotated in the opposite direction to gradually loosen the clamping plate 41. This operation process is simple and fast, which not only greatly saves the time of installation and disassembly, but also improves the convenience of operation for the operators.

[0042] Furthermore, the screw rod 42 also has a gripping portion 421, and the gripping portion 421 is provided with anti-slip texture or protrusions, so that it is convenient for the staff to use and can also increase the friction when gripping.

[0043] In this embodiment, the clamping assembly 40 further includes an elastic member 43, which is disposed in the connection groove 13, one end of the elastic member 43 abuts against the displacement seat 411, and the other end of the elastic member 43 abuts against the inner wall of the connection groove 13. When the clamping plates 41 move toward each other, the displacement seat 411 can press against the elastic member 43, so that the deformation of the elastic member 43 increases, thereby absorbing and dispersing the stress and vibration generated by clamping to a certain extent, thereby protecting the clamping assembly 40 and the boiler from damage. Optionally, the elastic member 43 can be set as a spring.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the mounting frame 10 includes a left side rod 131 and a right side rod 132 relatively located on both sides of the connecting groove 13, and a first limit block 412 and a second limit block 413 are provided on the clamping plate 41. The first limit block 412 and the second limit block 413 are relatively arranged on the left and right sides of the mounting frame 10, and the first limit block 412 and the displacement seat 411 define a first limit groove for the left side rod 131 to move, and the second limit block 413 and the displacement seat 411 define a second limit groove for the right side rod 132 to move.

[0045] The left side rod 131 and the right side rod 132 are clamped together to form a connection groove 13, that is, the left side rod 131 and the right side rod 132 are clamped on both sides of the displacement seat 411. The first limit block 412, the displacement seat 411 and the second limit block 413 form a structure similar to a mountain shape to be assembled with the mounting frame 10, which not only ensures the stability of the clamping plate 41 during the movement process, but also makes the entire clamping assembly 40 more compact and firm in structure.

[0046] Furthermore, guide rails 133 are provided on the left rod 131 and the right rod 132, and the first limit block 412 and the second limit block 413 are correspondingly provided with guide grooves 414 matching the guide rails 133, which can provide precise guidance for the movement of the clamping plate 41 and improve the sliding stability and smoothness of the clamping assembly 40.

[0047] Furthermore, the outer contour of the guide rail 133 is set to be Ω-shaped. Specifically, the convex parts on both sides of the guide rail 133 can effectively limit the lateral movement of the clamping plate 41, preventing it from shaking or deflecting during the movement; at the same time, the middle concave part of the guide rail 133 forms a closer fit with the guide groove 414, further improving the stability and smoothness of the sliding; thus, it can better adapt to the slight deformation and deflection of the clamping plate 41 during the movement, thereby ensuring that the clamping plate 41 always moves along a stable track.

[0048] like Figure 1 and Figure 3 As shown, in some embodiments, the clamping plate 41 is provided with a slot 415, and the slot 415 is used to fit the outer wall of the boiler. The fitting surface of the slot 415 can match the shape of the outer wall of the boiler, so that the slot 415 can fit closely with the outer wall of the boiler, thereby improving the connection strength between the clamping assembly 40 and the boiler, and ensuring that the descaling device always remains stable during operation, avoiding accidents caused by shaking or deviation.

[0049] like Figure 1 , Figure 4As shown, in some embodiments, the adjustment assembly 20 further includes a limit plate 23 and a pull rod 24, wherein the limit plate 23 is disposed above the slider 22, one end of the pull rod 24 is connected to the limit plate 23, and the other end of the pull rod 24 is provided with a handle 241. The limit plate 23 and the support rod 21 are disposed on both sides of the mounting frame 10, so that the slider 22 slides more smoothly in the first slide groove 11 and the second slide groove 12, and the installation of the adjustment assembly 20 is more stable.

[0050] Furthermore, the handle 241 may be provided with anti-slip textures or protrusions to increase the friction when holding.

[0051] like Figure 4 and Figure 5 As shown, in some embodiments, the sliding seat 31 includes a receiving groove 311 and a movable rod 312, the support rod 21 is movably arranged in the receiving groove 311, the movable rod 312 is arranged in the movable groove 211, and the two ends of the movable rod 312 are correspondingly connected to the inner wall of the receiving groove 311. In other words, the receiving groove 311 is designed as a groove, the support rod 21 is movably arranged in the receiving groove 311, and the outer surface of the support rod 21 is in contact with the inner wall of the receiving groove 311; the movable rod 312 is arranged in the movable groove 211 in the support rod 21, and the two ends of the movable rod 312 are connected to the inner wall of the receiving groove 311, so that the overall structural strength of the sliding seat 31 can be enhanced, and more reliable support and guidance can be provided for the movement of the support rod 21.

[0052] Further, the sliding seat 31 includes a Z-shaped plate 313 and a side wall plate 314. The side wall plate 314 is connected to one end of the Z-shaped plate 313 to define a receiving groove 311. The driver 33 is installed on the Z-shaped plate 313. The driver 33 and the receiving groove 311 are arranged side by side, making the overall structure more structural. In this embodiment, the Z-shaped plate 313 and the side wall plate 314 can be arranged as one body.

[0053] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the thermal power plant boiler descaling device 100 further includes a water supply assembly 50, which includes a water tank 51 and a water delivery pipe 52. The cleaning brush 32 is provided with a water inlet pipe 323 and a nozzle 322. The water delivery pipe 52 is connected to the water inlet pipe 323 to spray the water in the water tank 51 into the boiler channel through the nozzle 322. That is to say, when the descaling device is started, the nozzle 322 can finely atomize the clean water from the water tank 51 into countless tiny water droplets, and evenly spray them into each channel of the boiler through a specific spray angle and strength, which not only effectively removes the stubborn dirt in the inner wall and the channel of the boiler, but also further improves the cleanliness and thermal efficiency of the boiler through the flushing effect of water.

[0054] Furthermore, the cleaning brush 32 has a connecting shaft 321 connected to the telescopic rod 34, and a plurality of nozzles 322 are arranged, and the nozzles 322 are evenly arranged around the outer circumference of the connecting shaft 321, which not only ensures that the water mist can cover all channels of the boiler in an all-round and dead angle manner, but also greatly enhances the flushing force and coverage area of ​​the water mist through the synergistic effect of multiple nozzles 322, thereby more efficiently removing stubborn dirt on the inner wall and channels of the boiler.

[0055] During use, when the telescopic rod 34 drives the cleaning brush 32 to penetrate into the boiler, the connecting shaft 321 will rotate accordingly, so that the cleaning brush 32 and the nozzle 322 can fit closely to the wall of the boiler. At this time, multiple nozzles 322 will be started at the same time, and the clean water from the water tank 51 will be sprayed evenly into the boiler's hole in the form of atomization. In this process, the water mist can not only quickly soften and dissolve the dirt in the hole, but also peel off the dirt from the hole wall through a strong flushing effect, and finally be discharged from the outside of the boiler with the water flow.

[0056] Furthermore, the water supply assembly 50 further includes a frame 53, a universal wheel 54 is provided at the bottom of the frame 53, and a push rod 55 is provided on the frame 53, and the water tank 51 can be provided on the frame 53, so as to facilitate the movement of the water supply assembly 50. In this embodiment, a control box 56 is provided on the frame 53.

[0057] Optionally, the number of universal wheels 54 is four.

[0058] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the descaling assembly 30 includes a drill bit 35 disposed at the end of the cleaning brush 32, and a spiral blade 351 is disposed on the drill bit 35, so that the strong power generated by the drill bit 35 during the rotation process can be converted into a crushing and stripping effect on large pieces of dirt. When the drill bit 35 penetrates into the boiler channel and rotates, the spiral blade 351 will drive the water flow to form a strong impact force, which can quickly crush the large pieces of dirt in the channel and strip it from the channel wall. At the same time, the spiral structure of the blade can also smoothly discharge the crushed dirt particles to the outside of the boiler along the direction of the water flow, thereby avoiding the accumulation and blockage of dirt in the channel.

[0059] Furthermore, the drill bit 35 is configured to be conical. The tip of the cone has a smaller diameter and a larger contact area. When the drill bit 35 rotates and contacts the dirt, it can generate greater pressure and shear force, thereby more effectively crushing and peeling the dirt. This crushing effect not only improves the thoroughness of the scale removal, but also reduces the residue and accumulation of dirt particles in the pores, avoiding possible blockages and failures.

[0060] In addition, it should be noted that in the thermal power plant boiler descaling device 100 provided by the embodiment of the present invention, the driver 33 and the telescopic rod 34 can be configured to provide power to components such as a motor, thereby achieving precise driving and positioning of the cleaning brush 32 and the drill bit 35, improving the efficiency and quality of the descaling operation, and providing users with a more efficient and reliable descaling solution.

[0061] In summary, it can be seen that during use of the thermal power plant boiler descaling device 100 provided by the embodiment of the present invention: first, the clamping plate 41 is placed on the top of the boiler cylinder to ensure that the slot 415 is tightly fitted to the top edge of the boiler cylinder; then, the two relatively arranged clamping plates 41 are moved toward each other by rotating the screw 42, so that the clamping plates 41 are tightly fitted to the outer surface of the boiler cylinder, thereby realizing the installation and fixation of the clamping assembly.

[0062] Then, the driver 33 is started, and the driver 33 drives the telescopic rod 34 and the cleaning brush 32 to rotate. At the same time, the telescopic rod 34 is started, so that the telescopic rod 34 drives the cleaning brush 32 to move in the vertical direction of the boiler, so that the drill bit 35 can also clean the top hole of the boiler cylinder. During the cleaning process of the drill bit 35 and the cleaning brush 32, the water flow in the water supply component 50 can be sprayed out through the nozzle 322 at a certain pressure to perform all-round flushing of the boiler cylinder and the hole, thereby improving the descaling effect.

[0063] Finally, the pull rod 24 is pulled to move the adjustment assembly 20 along the first slide groove 11 and the second slide groove 12, so as to adjust the position of the cleaning brush 32 and ensure all-round cleaning of the inside of the boiler.
