Description

Technical Field

[0001] The present invention relates to the technical field of air supply and dust removal, and in particular to a powerful air supply and dust removal device and method for a wind power generation system. Background Art

[0002] As a clean, renewable energy source, wind energy is gaining increasing attention worldwide for its development and utilization. Wind power generation, with its technological maturity and scale-up advantages, has become a key pillar of the renewable energy sector. Wind turbine towers, as the core support structures of these systems, face the problem of dust accumulation on the surfaces of equipment within the towers during long-term operation. Traditional manual dust removal methods are inefficient and carry high operational risks. The continued accumulation of dust not only reduces the operating efficiency of distribution equipment and causes abnormal heating, but also hinders air circulation within the towers, causing localized temperature rises, creating potential safety hazards and ultimately impacting the stable operation of wind turbines.

[0003] In the prior art, a variety of solutions have been proposed to meet the needs of optimizing the environment inside the tower. For example, patent document CN206738090U discloses a dust removal and ventilation device for the tower base of a wind turbine, which innovatively sets a dual-channel structure of active air inlet windows and automatic air inlet windows on the tower body. An induced draft fan is arranged at the rear end of the active air inlet window to achieve directional introduction of external air; the automatic air inlet window is connected to the heat dissipation area of ​​the distribution equipment through a dedicated pipeline, and a branch pipe with an overflow window is arranged at a position opposite to its outlet, so as to avoid strong winds from impacting the equipment through a bypass pressure relief mechanism. The solution also monitors the air intake status in real time through a wind speed measuring device, and forms a linkage control with the induced draft fan, automatically increasing the ventilation volume when the natural air intake is insufficient, thereby taking into account both equipment protection and heat dissipation needs.

[0004] However, this type of design based on the combination of natural ventilation and mechanical assistance still has room for improvement: the air inlet window filter structure is easily clogged by large debris such as leaves, resulting in a reduction in the effective air inlet cross-sectional area; at the same time, the fixed air supply outlet has a single airflow direction, making it difficult to form multi-directional turbulence covering the inner wall of the tower, and its ability to remove suspended dust is limited. In addition, in the existing technology, in order to prevent the filter from being affected by debris, a brush plate that can swing to a certain angle is often provided. However, the general brush plate has a small swing angle range and cannot cover the entire filter, which reduces the cleaning effect. The above factors jointly restrict the improvement of the dust removal effect in the entire tower. Summary of the Invention

[0012] A dust removal method for a powerful air supply dust removal device for a wind power generation system comprises the following steps: When supplying air for dust removal, four powerful blowers are turned on at the same time to supply air. Due to the pressure, the external air flows into the air duct through the wind collecting hood, so that the external wind enters the tower body. While supplying air, impurities are blocked by the outer filter plate and the inner filter plate. In order to avoid the influence of impurities on air supply by blockage, the first drive component drives the shaft to drive the brush plate to rotate back and forth, that is, the brush plate swings back and forth, and then removes the debris adhering to the outer filter plate. In addition, the rotation of the support plate drives the powerful blower to rotate, so that the wind is blown out inward from the top of the tower body, thereby improving the dust removal effect, and then cooperates with the rotation of the scraper to scrape off the dust on the inner wall of the tower body, further improving the air supply and dust removal effect.

[0013] Preferably, when the inner filter plate needs to be disassembled and cleaned after being used for a period of time, the small bolts on the outer filter plate are removed first, and then the inner filter plate is quickly disassembled through the quick-release assembly, which reduces downtime and improves subsequent maintenance efficiency.

[0014] Preferably, while the powerful blower is delivering air, the L-shaped plate is driven to swing through the rotation of the drive shaft, in cooperation with the first eccentric head, the drive plate, the second eccentric head, the transmission plate, and the third eccentric head. The L-shaped plate drives the drive gear to rotate back and forth in cooperation with the arc-shaped rack, the limit gear, and the transmission gear, and then the drive gear drives the rotating shaft to rotate back and forth, and then the rotating shaft drives the brush plate to rotate back and forth, finally achieving reciprocating cleaning of the outer filter plate to avoid impurities from adhering.

[0015] Preferably, when external wind is sent into the tower body, by starting the second drive motor, the second drive motor drives the connecting shaft to rotate, so that the connecting shaft drives the upper gear plate to rotate, and the upper gear plate drives the support frame to move in a circle. Through the limit of the limiting component, the support frame drives the scraper to slide on the inner wall of the tower body to scrape dust, and then through the meshing transmission of the intermediate gear, the lower gear plate rotates under the limit of the limiting component, thereby driving the support plate to move synchronously, and the support plate finally drives the powerful blower to move in a circle, so that the airflow rotates inward and blows the inner wall of the tower body with strong force.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By designing a brush mechanism that can reciprocate over a wide angle, combined with a multi-stage eccentric and gear transmission system, the brushes achieve extensive cleaning coverage over the filter surface. This mechanism effectively removes large debris such as leaves, preventing a reduction in the filter's effective ventilation area. This solves the prior art issue of filter clogging, which can lead to reduced air intake efficiency.

[0017] 2. A rotatable, powerful blower group is driven by a support plate to create a spiral, multi-directional airflow. This dynamic airflow pattern generates strong turbulence on the tower's inner wall, completely removing suspended dust and overcoming the limitations of fixed air outlets in existing technologies, which suffer from limited airflow and insufficient dust removal coverage.

[0018] 3. By integrating a dual-action mechanism of rotating airflow and mechanical scraping, the rotating airflow simultaneously removes suspended dust while a synchronously driven scraper moves in a circular motion along the tower wall, directly removing deposited dust and preventing secondary adhesion. This design significantly improves tower wall cleanliness, resolving the existing pain point of relying solely on airflow to remove adhered dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-4The present invention provides a technical solution: a powerful air supply dust removal device and method for a wind power generation system, comprising: a tower body 1 and a concrete base 2 fixedly connected to the lower surface of the tower body 1, the tower body 1 is stably supported by the concrete base 2, the bottom of the tower body 1 is connected to one end of an air supply tube 3, the bottom of the tower body 1 is fixedly connected to the air supply tube 3, thereby expanding the air collection area and collecting wind from different directions to ensure the air intake. The other end of the air supply tube 3 is connected to one end of an air collecting cover 4, and the air collecting cover 4 is trumpet-shaped, thereby further expanding the air collection area. The inner ring surface is detachably connected to the inner filter plate 5 through a quick-release assembly. The impurities contained in the air are further removed by the setting of the inner filter plate 5. The other end of the wind collecting cover 4 is detachably connected to the outer filter plate 6 through a small bolt, so as to facilitate the subsequent disassembly of the outer filter plate 6. A reciprocating rotating shaft 7 is provided on the outer side of the outer filter plate 6. A brush plate 8 is fixed on one end of the rotating shaft 7. The other end of the rotating shaft 7 is connected to a first driving assembly for driving the rotating shaft 7 to rotate reciprocally. A support plate 9 is rotatably installed inside the bottom side of the tower body 1. Four powerful blowers 10 are fixed in the supporting plate 9. The supporting plate 9 A support frame 11 is rotatably installed on the upper side, and a plurality of scrapers 12 are fixedly connected to the upper surface of the support frame 11. The scrapers 12 are slidably connected to the inner wall of the tower body 1. A second driving assembly for driving the support frame 11 and the support plate 9 to rotate is installed on the lower side of the support plate 9. When supplying air and removing dust, four powerful blowers 10 are turned on at the same time to supply air. The high-speed rotation of the powerful blower 10 causes a pressure difference in the air. Due to the pressure, the external air flows into the air supply tube 3 through the wind collecting cover 4, thereby allowing the external wind to enter the tower body 1. While supplying air, it passes through the outer filter plate 6 and the inner filter plate 6. The filter plate 5 blocks foreign particles. To prevent impurities from blocking the air supply, the first drive assembly drives the rotating shaft 7 to drive the brush plate 8 to rotate back and forth, that is, the brush plate 8 swings back and forth, and then removes large debris such as leaves adhering to the outer surface of the outer filter plate 6. In addition, the rotation of the support plate 9 drives the powerful blower 10 to rotate, so that the wind blows inward from the top of the tower body 1, increasing the blowing force around the interior of the tower body 1 and improving the dust removal effect. Combined with the rotation of the scraper 12, the dust on the inner wall of the tower body 1 is scraped off, further improving the air supply and dust removal effect. Avoid secondary adhesion of dust.

[0023] The second embodiment: on the basis of the first embodiment, the quick-release assembly includes a limit frame 13, one side of the limit frame 13 is fixedly connected to the outer ring surface of the air supply tube 3 by a small bolt, and the other side of the limit frame 13 is slidingly sleeved with a limit rod 14, and the limit frame 13 limits the limit rod 14. One side of the limit frame 13 is hollow, and the top two ends of the limit rod 14 are fixedly connected to the bayonet pin 15, and the bayonet pin 15 is slidably connected with the bayonet pin 15 and the bayonet pin 15 is slidably connected with the bayonet slot 16 opened at the top of the limit frame 13. The bayonet slot 16 limits the bayonet pin 15, and the bottom of the limit rod 14 passes through the air supply tube 3 and is slidably plugged into the groove opened on the outer ring surface of the inner filter plate 5. The outer ring surface of the inner filter plate 5 is provided with four grooves, so that the limit rod 14 can limit and fix the inner filter plate 5 from four directions. A spring 17 is fixedly installed in the middle of the limit rod 14, and the spring 17 is limited and installed in the limit frame 13. When the inner filter plate 5 needs to be disassembled and cleaned after use for a period of time, the small bolts on the outer filter plate 6 are first removed, and then by pulling upward The limiting rod 14 and the spring 17 are compressed under the limit of the limiting frame 13 and the limiting rod 14, so that the top of the limiting rod 14 drives the bayonet 15 to slide out of the slot 16, and the bottom end of the limiting rod 14 slides out of the groove opened on the outer ring surface of the inner filter plate 5, thereby releasing the limit on the inner filter plate 5. Then the limiting rod 14 is twisted to rotate the limiting rod 14 with the bayonet 15. When the bayonet 15 rotates to the stepped groove opened on the top of the limiting frame 13, the inner filter plate 5 can be taken out for maintenance or cleaning. When the inner filter plate 5 needs to be installed, it is only necessary to open a groove on the outer ring surface of the inner filter plate 5 to be coaxial with the limit rod 14, twist the limit rod 14 in the opposite direction, and under the reverse elastic force of the spring 17, the bottom of the limit rod 14 slides into the groove, thereby limiting and fixing the inner filter plate 5. The setting of the inner filter plate 5 further blocks the entry of external dust and other impurities, ensuring the cleanliness of the incoming air. At the same time, the installation and removal of the inner filter plate 5 is convenient, which reduces downtime and improves the efficiency of subsequent maintenance.
