Description

Technical Field

[0001] This invention relates to the field of centrifugal dust removal technology, specifically to an adaptive adjustment dust collection device for fan blades and its dust removal method. Background Technology

[0002] In industrial production settings, fan blades, as core components of ventilation and power transmission systems, are prone to accumulating large amounts of dust due to prolonged exposure to dusty conditions. Large-area inclined and curved surfaces are also susceptible to stubborn dust buildup due to airflow disturbances and electrostatic adsorption. This dust accumulation not only reduces equipment operating efficiency and increases energy consumption but may also cause safety hazards such as vibration and corrosion. Therefore, cleaning dust from these special surfaces is a crucial step in ensuring stable equipment operation.

[0003] Existing dust cleaning technologies have many shortcomings and are difficult to meet the needs of actual operations. Current technical solutions generally have poor adaptability for dust cleaning of wind turbine blade surfaces, large-area inclined surfaces, and curved surfaces. Most existing cleaning devices are unable to achieve close contact and full coverage with these complex curved surfaces, and cleaning dead zones are easily created during the cleaning process, resulting in dust that cannot be completely removed.

[0004] Existing cleaning technologies suffer from limited airflow patterns, making it difficult to effectively disperse stubborn dust deposits. Furthermore, some solutions lack targeted electrostatic removal mechanisms, allowing dust to remain or re-adhere due to electrostatic adsorption, further exacerbating the problem of incomplete cleaning. In addition, existing dust collection systems suffer from poorly designed airflow channels, resulting in low dust removal efficiency. Blown-off dust can easily spread and pollute the factory environment, and the operating intervals of most devices cannot be precisely controlled. Rigid contact cleaning can easily scratch delicate surfaces such as fan blades, while non-contact cleaning is prone to secondary dust adhesion due to airflow recirculation.

[0005] The existing device has a simple adjustment structure, which cannot flexibly adapt to the needs of different working positions and different pitch angles. This makes the cleaning operation of the wind turbine blade surface, large-area inclined surface and curved surface cumbersome and inefficient. Ultimately, it makes it inconvenient to clean dust on these special surfaces and the cleaning effect is poor, which seriously restricts the operation and maintenance quality and service life of related equipment. Summary of the Invention

[0006] This invention provides an adaptive adjustment dust collection device for fan blades, which effectively removes dust from the surface of exhaust fan blades and large-area inclined and curved surfaces.

[0008] Furthermore, the sliding member includes: A first mounting groove is formed on a support plate; a first slide block is fixed in the first mounting groove; a first slide rail is slidably inserted into the first slide block; and a first sliding plate is fixed on the first slide rail.

[0009] Furthermore, the sliding member also includes: The first drive seat is fixed above the support plate; the first external rotor motor is rotatably mounted on the first drive seat; the first drive pulley is fixed on the outside of the first external rotor motor; the first toothed belt is sleeved on the first drive pulley at both ends; the first linkage plate is fixed at one end on the first toothed belt and at the other end on the first sliding plate.

[0010] Furthermore, the sliding member also includes: The second mounting slot is formed on the first sliding plate; the second slide block is fixed in the second mounting slot; the second slide rail is slidably inserted into the second slide block; and the second sliding plate is fixed on the second slide rail.

[0011] Furthermore, the sliding member also includes: The second drive seat is fixed below the first sliding plate; the second outer rotor motor is rotatably mounted on the second drive seat; the second drive pulley is fixed to the outside of the second outer rotor motor; the second toothed belt is sleeved on the second drive pulley at both ends; the second linkage plate is fixed at one end on the second toothed belt and at the other end on the second sliding plate.

[0012] Furthermore, the sway member includes: A swing angle support is fixed to the second sliding plate; a swing angle motor is fixed to the swing angle support; and a swing angle rotating base is fixed to the side of the swing angle support near the swing angle motor.

[0013] Furthermore, the sway member also includes: The first swing angle pulley is fixed to the output end of the swing angle motor; the swing angle rod is rotatably inserted into the swing angle rotating base; the second swing angle pulley is fixed at the middle position of the swing angle rod; the swing angle belt has one end sleeved on the first swing angle pulley and the other end sleeved on the second swing angle pulley; the swing angle plate is fixedly sleeved on both ends of the swing angle rod; the docking plate is fixed on the end of the swing angle plate away from the swing angle rod; the docking rod has one end fixed on the docking plate and the other end fixed on the dust collection support.

[0014] Furthermore, it also includes: An extension plate is slidably mounted on a positioning plate; a motor base is fixed on the extension plate; a drive motor is fixed on the motor base; a transmission base is fixed on both sides of the extension plate; a threaded shaft is fixed on the drive motor, with both ends rotatably mounted on the transmission base; and a threaded sleeve is fixed on a support plate and threadedly connected to the threaded shaft.

[0015] Secondly, a dust removal method for a fan blade adaptive adjustment dust collection device, the steps of which are as follows: S1. Start the air compressor. The air compressor continuously supplies compressed air to the high-pressure nozzle. The compressed air enters the internal chamber of the dust collection box through the high-pressure nozzle and is then divided into twelve swirl caps. Part of the compressed air flows out at high speed from the swirl outlet of the swirl cap and drives the swirl cap to rotate around its own axis with the help of the airflow reaction force. The other part is sprayed out from the cleaning nozzle of the swirl cap. S2. The rotation of the swirl cap drives the cleaning nozzle to rotate synchronously, causing the high-speed airflow ejected from the cleaning nozzle to overlap and form a stable rotating airflow field. The impact force of the airflow is used to peel off the dust attached to the surface of the fan blades, large-area inclined surfaces, and curved surfaces. The dispersed dust follows the rotating airflow field and rotates. Under the centrifugal force of the rotating airflow field, the dust's own gravity, and inertia, it is effectively separated from the rotating airflow field. The suction roller is attached to the surface of the fan blades, and the rotating airflow field is used to disperse the stubborn dust deposited, avoiding residue. S3. Start the dust collector. The dust collector draws air through the exhaust main pipe, creating a negative pressure in the exhaust main pipe, exhaust branch pipe, and dust collection box. Under the action of negative pressure suction, dust particles that have been separated from the rotating airflow field are quickly sucked into the dust collection port. After entering the dust collection box, they are transported to the dust collector along with the dust-laden air through the exhaust branch pipe and exhaust main pipe, completing the removal of dust from the surface of the fan blades, large-area inclined surfaces, and curved surfaces. S4. Synchronously start the ion bar. The ion bar is connected to an external power source through the ion interface to generate an ion airflow, which neutralizes the static electricity on the surface of the fan blades and the surrounding air, eliminates the static adsorption effect, and prevents dust from adhering again.

[0016] Furthermore, the dust removal method steps are as follows: S5. Adjust the output power of the air compressor as needed to build a dynamic adaptive control of power, airflow and work efficiency; when it is necessary to increase the dust removal intensity, increase the output power of the air compressor to increase the compressed air pressure and flow rate simultaneously, and increase the kinetic energy of the airflow from the cleaning nozzle and swirl port. S6. After the airflow driving force at the swirl inlet is enhanced, the rotation speed of the swirl cap increases synchronously. The high-speed rotation of the swirl cap intensifies the airflow rotation disturbance effect, realizes the secondary amplification of airflow energy, and enhances the penetration of the rotating airflow field. At the same time, it enhances the centrifugal force of the rotating airflow field, further improving the separation efficiency of dust particles and airflow. S7. The airflow pressure drives the flexible rubber cleaning nozzle to produce precise elastic deformation, and the tilt angle of the cleaning nozzle gradually increases towards the outside of the vortex cap. Furthermore, the cleaning nozzle tilts towards the multiple V-shaped grooves on the outside of the vortex cap, ensuring that the tilt angle increases synchronously with the increase in airflow. By adaptively adjusting the angle of the cleaning nozzle, the coverage area of ​​the rotating airflow field can be expanded and the airflow velocity accelerated, forming a composite dust removal airflow pattern with wide-area full coverage and high-velocity precise impact, adapting to different pollution conditions. The expanded airflow field quickly disperses large areas of floating dust, achieving efficient separation of floating dust and airflow through centrifugal force and gravity. For stubborn dust deposits, a strong airflow beam is formed by high-velocity airflow to precisely impact the attachment point. The peeled-off stubborn dust is separated under the action of the rotating airflow field and then quickly sucked away by the suction port. Simultaneously, a preset distance is maintained between the cleaning nozzle and the working surface to avoid scratches or wear, and to prevent airflow backflow from causing secondary dust adhesion.

[0017] The above-described solution of the present invention has at least the following beneficial effects: This invention uses compressed air to drive the rotation of a swirling air cap. The swirling air cap and the cleaning nozzle form an adaptive rotating airflow generation structure. The high-speed airflow, after being ejected through the cleaning nozzle, superimposes to form a stable rotating airflow field. The strong impact force of the airflow achieves efficient removal and powerful cleaning of dust from the equipment surface. Addressing the problem of electrostatic adsorption of dust, an ion bar is included for electrostatic elimination. The ion bar, connected to an external power source via an ion interface, generates a directional ion airflow that quickly neutralizes static electricity on the equipment surface and surrounding air, preventing dust residue caused by electrostatic adsorption at its source. To achieve a clean working environment, a closed-loop dust removal circuit is designed, using the suction port as the core dust removal interface. A graded airflow channel is constructed through exhaust branch pipes and the main exhaust pipe, precisely connecting to the negative pressure dust collector, allowing the dust to be blown away... Dust can be quickly sucked into the dust collector for purification, completely preventing dust from spreading and polluting the factory. In terms of operational adaptability and protective design, the dust collection box, as the core dust collection component, adopts an adaptive fitting structure at its rear end, which can drive the dust collection component to fit tightly against the product surface. At the same time, dust collection rollers are installed on both sides of the dust collection support via roller supports. On the one hand, this precisely controls the working gap between the dust collection box and the product. On the other hand, rolling friction replaces sliding friction, minimizing the risk of contact surface and operational damage. The rear end of the device integrates a sliding component telescopic structure and a swing component rotation architecture. Through the coordinated operation of the two, the dust collection box can be flexibly switched at different working positions and different tilt angles, greatly improving the adaptability and dust collection capability for complex curved surfaces and multi-angle equipment.

[0018] This invention utilizes the rotation of a cyclone cap to drive the cleaning nozzle, creating a stable rotating airflow field. Combined with a negative pressure dust collection system, it efficiently removes and quickly extracts dust from the surface of fan blades and large-area inclined and curved surfaces. The rotating airflow field also disperses stubborn dust deposits; the dispersed dust follows the rotating airflow field, and under the centrifugal force, gravity, and inertia of the airflow field, it is effectively separated from the dust. Furthermore, by adjusting the output power of the air compressor, dynamic adaptive control can be achieved, precisely matching the dust removal intensity with the operating range. The airflow pressure can drive a flexible rubber material... The high-quality cleaning nozzle adaptively deforms, expanding the coverage area of ​​the rotating airflow field and accelerating the flow velocity to form a composite dust removal pattern, adapting to different pollution conditions. The cleaning nozzle always maintains a preset distance from the working surface, avoiding scratches on the working surface or wear on the device caused by direct contact. At the same time, the preset distance can prevent secondary dust adhesion caused by airflow backflow. The cleaning nozzle uses the elastic properties of flexible rubber to achieve adaptive angle adjustment and deformation driven by airflow, eliminating the need for an additional drive mechanism, simplifying the structure and reducing energy consumption. Furthermore, the sliding and swing angle adjustment structure can further expand the working range to adapt to the operational needs under different working conditions. Attached Figure Description

[0024] Specifically, the support plate 1, as the basic load-bearing component of the device, provides a stable installation benchmark for the positioning plate 2 and the sliding component 3; the positioning plate 2 is slidably connected to the extension plate 18 to achieve the overall positioning and erection of the entire device; the sliding component 3 can slide along the length of the support plate 1, thereby driving the fixed corner component 4, the dust collection support 5, and the dust collection box 6 to move synchronously, expanding the working range; the dust collection support 5 provides a sealing and fixing space for the dust collection box 6, ensuring the structural stability of the dust collection box 6 during operation; the dust collection box 6 is the core dust removal chamber, and the dust collection ports 9 on its upper and lower sides are used to draw in dust-laden air; the high-pressure air nozzle 10 is used to connect to an external high-pressure air source to supply air to the dust collection box.

[0029] In another preferred embodiment of the present invention, the swing member 4 includes: a swing support 401, fixed on the second sliding plate 3013; a swing motor 402, fixed on the swing support 401; and a swing rotatable seat 403, fixed on the side of the swing support 401 near the swing motor 402.

[0030] The swaying component 4 also includes: a first swaying pulley 404, fixed to the output end of the swaying motor 402; a swaying rod 405, rotatably inserted into the swaying base 403; a second swaying pulley 406, fixed at the middle position of the swaying rod 405; and a swaying belt 407, one end of which is sleeved on the first swaying pulley 404 and the other end of which is sleeved on the second swaying pulley 406.

[0031] The corner component 4 also includes: a corner plate 408, which is fixedly sleeved on both ends of the corner rod 405; a docking plate 409, which is fixed on the end of the corner plate 408 away from the corner rod 405; and a docking rod 4010, which is fixed on the docking plate 409 at one end and on the dust collection support 5 at the other end.

[0032] Specifically, the swing bracket 401 is fixed to the second sliding plate 3013 by bolts, providing a coaxial mounting reference for the swing motor 402 and the swing rotating seat 403, ensuring precise transmission between the two; the swing rotating seat 403 has a bearing inside, and the swing rod 405 is inserted into the bearing, which can reduce the frictional resistance when the swing rod 405 rotates and ensure smooth rotation; the two ends of the docking rod 4010 are rigidly connected to the docking plate 409 and the dust collection bracket 5 respectively, converting the swing of the swing plate 408 into the angle adjustment of the dust collection bracket 5, and finally realizing the swing angle adjustment of the dust collection box 6 to adapt to the operation requirements of different curved and inclined surfaces.

[0033] Working principle: The support plate 1 is fixedly installed on the extension plate 18 through the positioning plate 2. The outer shell of the dust collection bracket 5 is equipped with a shell to achieve protection and sealing functions. The exhaust pipe 8 is connected to an external dust collector to export and purify dusty air. The high-pressure air nozzle 10 is connected to an air compressor to obtain a high-pressure air source. During operation, the extension plate 18, support plate 1 and positioning plate 2 are erected to a specified height through the external bracket, so that the dust collection box 6 is aligned with the surface of the fan blades at a high position, which can specifically complete the dust removal treatment of the fan blade surface. At the same time, it is suitable for dust removal operations on large-area inclined surfaces and curved surfaces, achieving efficient dust removal effect in multiple scenarios.

[0034] After the air compressor is started, it continuously supplies compressed air to the high-pressure nozzle 10. The compressed air enters the internal chamber of the dust collection box 6 through the high-pressure nozzle 10. The compressed air in the dust collection box 6 is then divided into twelve swirl caps 11. Part of the compressed air flows out at high speed from the swirl outlet 13 of the swirl cap 11, and the reaction force of the airflow drives the swirl cap 11 to rotate around its own axis. The other part of the compressed air is sprayed outward from the cleaning nozzle 12 of the swirl cap 11. During the rotation of the swirl cap 11, the cleaning nozzle 12 is driven to rotate synchronously, so that the high-speed air fluids sprayed from the cleaning nozzle 12 overlap to form a stable rotating airflow field. The rotating airflow field uses the strong airflow impact force to remove dust attached to the surface of the fan blades, large-area inclined surfaces, and curved surfaces. On the other hand, the dispersed dust will follow the rotating airflow field to rotate. Under the centrifugal force of the rotating airflow field, the dust's own gravity, and inertia, the dust will be affected by the centrifugal force of the rotating airflow field. The dust particles are effectively separated from the rotating airflow field. During operation, the dust collection roller 17 is attached to the surface of the fan blades. The rotating airflow field can effectively disperse the stubborn dust deposited on the surface of the fan blades, preventing dust residue. Then, the dust collector is started. The dust collector draws air through the exhaust main pipe 8, so that the exhaust main pipe 8, the exhaust branch pipe 7, and the dust collection port 9 of the dust collection box 6 are all in a negative pressure state. Under the action of negative pressure suction, the dust particles that have been separated from the rotating airflow field are quickly sucked into the dust collection port 9, enter the dust collection box 6, and are drawn into the exhaust branch pipe 7 along with the dust-laden air. Then, they are merged into the exhaust main pipe 8 and transported to the dust collector, realizing the effective removal of dust from the surface of the fan blades, large-area inclined surfaces, and curved surfaces. At the same time, the ion bar 14 is started. The ion bar 14 is connected to an external power source through the ion interface 15. The generated ion airflow can neutralize the static electricity on the surface of the fan blades and the surrounding air, eliminate the static adsorption effect, and prevent dust from re-attaching due to static electricity.

[0035] Adjusting the output power of the air compressor allows for dynamic adaptive control of power, airflow, and operational efficiency, achieving precise matching between dust removal intensity and operational range, breaking through the limitations of fixed operating parameters in traditional dust removal devices. When the power increases, the output compressed air pressure and flow rate increase simultaneously, significantly enhancing the kinetic energy of the high-speed airflow ejected from the cleaning nozzle 12 and swirl nozzle 13. The enhanced airflow driving force at the swirl nozzle 13 directly drives the rotation speed of the swirl cap 11 to increase synchronously. The high-speed rotation of the swirl cap 11 not only further intensifies the rotational disturbance effect of the airflow, forming a secondary amplification of airflow energy, making the impact force of the rotating airflow field more penetrating, but also enhances the centrifugal force of the rotating airflow field, improving the separation efficiency of dust particles and airflow. The cleaning nozzle 12 adopts an inclined structure design, combined with flexible rubber material. This flexible rubber material is not for contact protection, but rather utilizes its elastic properties to achieve adaptive angle adjustment and deformation under airflow drive. Multiple V-shaped grooves are opened on the outside of the cleaning nozzle 12 facing the swirl cap 11, ensuring that the airflow ejected from the cleaning nozzle 12 increases, thus tilting along the multiple V-shaped grooves. During operation... The cleaning nozzle 12 maintains a preset distance from the working surfaces such as the fan blades and curved surfaces to avoid scratches or wear on the working surfaces caused by direct contact. As the compressed air flow increases, the airflow from the cleaning nozzle 12 also increases. Simultaneously, the airflow pressure drives the flexible rubber cleaning nozzle 12 to undergo precise elastic deformation, causing its tilt angle to gradually increase towards the outside of the swirling air cap 11. This adaptive angle adjustment design, requiring no additional drive mechanism, allows the coverage area of ​​the rotating airflow field to expand linearly with the airflow pressure, while further increasing the airflow velocity. It quickly forms a composite dust removal airflow pattern that provides wide-area coverage and high-velocity precise impact. It can rapidly sweep away large areas of floating dust through the expanded airflow field, achieving efficient separation of floating dust and airflow with the help of centrifugal force and gravity. It can also target stubborn dust deposits by forming a strong airflow jet with high-velocity airflow to precisely impact the attachment point. The stubborn dust that has been peeled off is separated under the action of the rotating airflow field and then quickly sucked away by the suction port 9. This greatly improves the dust removal efficiency and cleanliness under different pollution conditions. At the same time, the preset spacing design can also avoid the problem of secondary dust adhesion caused by airflow backflow.

[0036] Start the drive motor 20, which drives the threaded shaft 22 to rotate. The rotation of the threaded shaft 22 causes the threaded sleeve 23 to screw in or out, thereby adjusting the extension and retraction of the support plate 1 on the extension plate 18. Start the first external rotor motor 306, whose output shaft drives the first drive pulley 307 to rotate. The first drive pulley 307 drives the first toothed belt 308 to rotate cyclically around the pulley track through friction. During the rotation of the first toothed belt 308, it drives the first linkage plate 309, which is fixedly connected to it, to move along the belt drive direction. The displacement of the first linkage plate 309 synchronously drives the first sliding plate 304 and the first slide rail 303 fixed to the first sliding plate 304, so that the first slide rail 303 slides smoothly within the first slide block 302, and finally the first sliding plate 304 extends outward from the support plate 1. Then start the second external rotor motor 3015, which drives the second external rotor motor 301 to rotate. The output shaft of 15 drives the second drive pulley 3016 to rotate, the second drive pulley 3016 drives the second toothed belt 3017 to rotate cyclically, the second toothed belt 3017 drives the second linkage plate 3018 fixed thereto to move, the second linkage plate 3018 drives the second sliding plate 3013 and the second slide rail 3012 fixed on the second sliding plate 3013 to slide within the second slide block 3011, so that the second sliding plate 3013 extends outward from the first sliding plate 304; through the linkage of the above two-stage sliding mechanism, the support plate 1, the first sliding plate 304 and the second sliding plate 3013 form a telescopic integral structure, effectively extending the working length of the device, adapting to the dust removal needs of longer distances or larger areas, ensuring that the rotating airflow field can cover a longer and wider working area, and after completing the dust peeling and separation of different working surfaces, the dust is fully sucked up through the dust suction port 9.

[0037] When the swing angle motor 402 is started, its output shaft drives the first swing angle pulley 404 to rotate. The first swing angle pulley 404 transmits power to the second swing angle pulley 406 through the swing angle belt 407, driving the second swing angle pulley 406 to rotate synchronously. The second swing angle pulley 406 is fixedly connected to the swing angle rod 405, causing the swing angle rod 405 to rotate around its own axis within the swing angle rotating seat 403. When the swing angle rod 405 rotates, it causes the swing angle plates 408, which are fixedly sleeved at both ends, to swing synchronously. The swing of the swing angle plates 408 causes the mating plate 40, which is fixed to them, to swing synchronously. 9. The docking plate 409 drives the dust collection support 5 to swing through the docking rod 4010; the swing of the dust collection support 5 directly drives the internally fixed dust collection box 6 to swing synchronously. By adjusting the rotation angle of the swing angle motor 402, the swing angle of the dust collection box 6 can be precisely controlled, so that the rotating airflow field generated by the dust collection box 6 can accurately fit the contour of the fan blade surface, large-area inclined surface and curved surface, ensuring that the working surface with different curvature and tilt angle can be covered by the rotating airflow field, completing the uniform peeling and efficient separation of dust, and then achieving a uniform and efficient dust removal effect through the dust collection port 9.

[0038] Embodiments of the present invention provide a dust removal method for an adaptive adjustment dust collection device for wind turbine blades, the steps of which are as follows: S1. Start the air compressor. The air compressor continuously supplies compressed air to the high-pressure nozzle 10. The compressed air enters the internal chamber of the dust collection box 6 through the high-pressure nozzle 10, and then is divided into twelve swirl caps 11. Part of the compressed air flows out at high speed from the swirl port 13 of the swirl cap 11. With the help of the airflow reaction force, the swirl cap 11 is driven to rotate around its own axis. The other part is sprayed outward from the cleaning nozzle 12 of the swirl cap 11. S2. The rotation of the swirl cap 11 drives the cleaning nozzle 12 to rotate synchronously, so that the high-speed air fluid ejected from the cleaning nozzle 12 overlaps to form a stable rotating airflow field. The airflow impact force is used to peel off the dust attached to the surface of the fan blades, large-area inclined surfaces and curved surfaces. The dispersed dust follows the rotating airflow field and rotates. Under the centrifugal force of the rotating airflow field, the dust's own gravity and inertia, it is effectively separated from the rotating airflow field. The dust suction roller 17 is attached to the surface of the fan blades and disperses the stubborn dust deposited by the rotating airflow field to avoid residue. S3. Start the dust collector. The dust collector draws air through the exhaust main pipe 8, creating a negative pressure in the exhaust main pipe 8, exhaust branch pipe 7, and dust collection box 6's suction port 9. Under the action of negative pressure suction, dust particles that have been separated from the rotating airflow field are quickly sucked into the suction port 9 and enter the dust collection box 6. After entering the dust-laden air, they are transported to the dust collector through the exhaust branch pipe 7 and exhaust main pipe 8, completing the removal of dust from the fan blade surface, large-area inclined surface, and curved surface. S4. Synchronously start the ion bar 14. The ion bar 14 is connected to an external power source through the ion interface 15 to generate an ion airflow, which neutralizes the static electricity on the surface of the fan blades and the surrounding air, eliminates the static adsorption effect, and prevents dust from adhering again. S5. Adjust the output power of the air compressor as needed to build a dynamic adaptive control of power, airflow and work efficiency; when it is necessary to increase the dust removal intensity, increase the output power of the air compressor to increase the compressed air pressure and flow rate simultaneously, and increase the kinetic energy of the airflow from the cleaning nozzle 12 and the swirl port 13. After the airflow driving force at S6 and swirl inlet 13 is enhanced, the rotation speed of swirl cap 11 increases synchronously. The high-speed rotation of swirl cap 11 intensifies the airflow rotation disturbance effect, realizes secondary amplification of airflow energy, and enhances the penetration of the rotating airflow field. At the same time, it enhances the centrifugal force of the rotating airflow field, further improving the separation efficiency of dust particles and airflow. S7. The airflow pressure drives the flexible rubber cleaning nozzle 12 to produce precise elastic deformation. The tilt angle of the cleaning nozzle 12 gradually increases towards the outside of the vortex air cap 11. The cleaning nozzle 12 tilts towards itself towards the multiple V-shaped grooves on the outside of the vortex air cap 11, ensuring that the tilt angle increases synchronously when the airflow increases. With the adaptive adjustment and deformation of the cleaning nozzle 12, the coverage area of ​​the rotating airflow field can be expanded and the airflow velocity can be accelerated, forming a composite dust removal airflow pattern with large-area full coverage and high-velocity precise impact, which is suitable for different pollution conditions. The expanded airflow field quickly sweeps away large areas of floating dust, and the centrifugal force and gravity are used to achieve efficient separation of floating dust and airflow. For stubborn dust deposits, the high-velocity airflow forms a strong airflow jet that precisely impacts the attachment point. The stubborn dust after being peeled off is separated under the action of the rotating airflow field and then quickly sucked away by the suction port 9. At the same time, the cleaning nozzle 12 is kept at a preset distance from the working surface to avoid scratches or wear and to prevent airflow backflow from causing secondary dust adhesion.

The dust removal method steps are as follows: S1. Start the air compressor. The air compressor continuously supplies compressed air to the high-pressure nozzle. The compressed air enters the internal chamber of the dust collection box through the high-pressure nozzle and is then divided into twelve swirl caps. Part of the compressed air flows out at high speed from the swirl outlet of the swirl cap and drives the swirl cap to rotate around its own axis with the help of the airflow reaction force. The other part is sprayed out from the cleaning nozzle of the swirl cap. S2. The rotation of the swirl cap drives the cleaning nozzle to rotate synchronously, causing the high-speed airflow ejected from the cleaning nozzle to overlap and form a stable rotating airflow field. The impact force of the airflow is used to peel off the dust attached to the surface of the fan blades, large-area inclined surfaces, and curved surfaces. The dispersed dust follows the rotating airflow field and rotates. Under the centrifugal force of the rotating airflow field, the dust's own gravity, and inertia, it is effectively separated from the rotating airflow field. The suction roller is attached to the surface of the fan blades, and the rotating airflow field is used to disperse the stubborn dust deposited, avoiding residue. S3. Start the dust collector. The dust collector draws air through the exhaust main pipe, creating a negative pressure in the exhaust main pipe, exhaust branch pipe, and dust collection box.

The airflow pressure drives the flexible rubber cleaning nozzle to produce precise elastic deformation, and the tilt angle of the cleaning nozzle gradually increases towards the outside of the vortex cap. Furthermore, the cleaning nozzle tilts towards the multiple V-shaped grooves on the outside of the vortex cap, ensuring that the tilt angle increases synchronously with the increase in airflow. By adaptively adjusting the angle of the cleaning nozzle, the coverage area of ​​the rotating airflow field can be expanded and the airflow velocity accelerated, forming a composite dust removal airflow pattern with wide-area full coverage and high-velocity precise impact, adapting to different pollution conditions. The expanded airflow field quickly disperses large areas of floating dust, achieving efficient separation of floating dust and airflow through centrifugal force and gravity. For stubborn dust deposits, a strong airflow beam is formed by high-velocity airflow to precisely impact the attachment point. The peeled-off stubborn dust is separated under the action of the rotating airflow field and then quickly sucked away by the suction port. Simultaneously, a preset distance is maintained between the cleaning nozzle and the working surface to avoid scratches or wear, and to prevent airflow backflow from causing secondary dust adhesion.
