Description

Technical Field

[0001] This application relates to the field of wind turbine technology, and in particular to a device and mechanism for removing flutter nets for wind turbines. Background Technology

[0002] With the development of wind power technology, the length of wind turbine blades has exceeded 110 meters. During the shutdown period between the installation of the wind turbine and grid connection, stationary blades are prone to flutter under certain wind conditions, which can lead to blade breakage or tower collapse in severe cases. To mitigate this risk, the industry commonly uses temporary flutter netting to cover the blade surface. This flutter netting must be removed before the wind turbine is connected to the grid for power generation.

[0003] In existing technologies, the removal of flutter nets mainly relies on manual high-altitude operations. Workers need to operate suspended hundreds of meters in the air with the help of spiders or suspended baskets, which poses certain risks to high-altitude operations and makes it difficult to guarantee personal safety. At the same time, manual operation is inefficient and is severely restricted by weather conditions, with a short working window, which in turn affects the progress of wind turbine grid connection. Summary of the Invention

[0004] The purpose of this application is to provide a device and mechanism for removing anti-flutter nets for wind turbines. Operators only need to control the moving mechanism from the ground via remote control to complete the high-altitude removal operation, eliminating the need for personnel to climb high and thus eliminating the safety risk of falling from heights.

[0005] In a first aspect, the present invention provides a device for removing anti-flutter nets for wind turbines, comprising: The moving mechanism is configured to be placed on and move on the outer wall of the fan. A dismantling mechanism is mounted on the moving mechanism; the dismantling mechanism includes: The base has a sliding support surface at its bottom for sliding contact with the outer wall of the fan; the front end of the base is provided with a guide part, which has an inclined guide surface. From the front end to the rear end of the base, the guide surface gradually increases in height, which is used to lift the anti-flutter net attached to the outer wall of the fan when the base moves along the outer wall of the fan. A cutting assembly, mounted on the base, is used to cut the anti-flutter net raised by the guide section.

[0006] Beneficial effects: This flutter net removal device features a guide section with a gradually increasing guide surface on the base. When the moving mechanism drives the removal mechanism along the outer wall of the fan, the base moves along the outer wall, and the guide section smoothly lifts the flutter net that is tightly attached to the blade surface and feeds it into the cutting component, which then cuts it off. Throughout the process, operators only need to control the moving mechanism from the ground using a remote control to complete the high-altitude removal operation, eliminating the need for personnel to climb and thus eliminating the safety risk of falls from heights.

[0007] Furthermore, the bottom of the base is a sliding support surface that slides in contact with the outer wall of the wind turbine. Compared to manually suspending the tool, the sliding support surface can evenly distribute the weight of the dismantling mechanism, avoiding localized pressure concentration that could cause indentations or scratches on the blade surface. Combined with the guide section at the front of the base, the anti-flutter mesh can be lifted first, preventing the cutting components from directly contacting the blade surface and further ensuring the integrity of the blade paint and anti-corrosion layer.

[0008] Meanwhile, compared to the shortcomings of traditional manual high-altitude demolition methods, which rely on weather conditions, have short working windows, and are inefficient, this anti-flutter net demolition device uses a moving mechanism to drive the demolition mechanism to move and cut automatically. The demolition time for a single wind turbine can be shortened from several days to several hours, improving demolition efficiency and helping wind farms to connect to the grid for power generation in a timely or early manner.

[0009] In one optional embodiment, the base is further provided with a guide plate, which is located behind the guide portion. The guide plate is gradually raised from the front end to the rear end of the base, and is used to guide the anti-vibration net raised by the guide portion to the cutting assembly.

[0010] Beneficial effects: The guide plate is located on the base and behind the guide section. The guide section and the guide plate are arranged sequentially from the front end to the rear end of the base. After the guide section lifts the anti-flutter mesh attached to the outer wall of the fan, the anti-flutter mesh continues to move backward along the guide section's guide surface. At this time, the guide plate receives the lifted anti-flutter mesh and guides it further to the cutting area of ​​the cutting assembly. The guide plate is gradually raised from front to back, forming a continuous transition in height with the guide section's guide surface. This ensures that the anti-flutter mesh enters the cutting assembly with a smooth trajectory after being lifted, avoiding stacking or jamming of the anti-flutter mesh due to sudden height changes.

[0011] In one alternative embodiment, the width of the guide portion is greater than the width of the guide plate along the width direction of the base.

[0012] Beneficial effects: Because the width of the guide section is greater than the width of the guide plate, the guide section can lift the anti-flutter net from the blade surface with a wider pickup surface, covering a wider working area and avoiding the failure to pick up some anti-flutter net due to positional misalignment or excessive width. During the transition of the anti-flutter net from the guide section to the guide plate, as the width gradually narrows, the anti-flutter net is gathered towards the center, facilitating the cutting assembly to cut the gathered anti-flutter net at a predetermined cutting position, avoiding incomplete cutting or misalignment due to excessive width or positional misalignment of the anti-flutter net.

[0013] In one optional embodiment, the dismantling mechanism further includes a mounting base, which is connected to the base at an angle, and the mounting base has a through hole and a mounting hole. The cutting component is inserted into the through hole and is detachably connected to the mounting base by fasteners inserted into the mounting hole.

[0014] Beneficial effects: The mounting base's structure makes assembling the cutting component with the base much easier. The cutting component is positioned via a through hole and then locked in place with fasteners through the mounting holes; this separation of positioning and locking functions improves assembly accuracy and efficiency. Furthermore, the detachable connection facilitates maintenance, replacement, and repair of the cutting component, reducing long-term operating costs.

[0015] In one optional embodiment, the cutting assembly includes a drive member and a cutting blade, the drive member being used to drive the cutting blade to rotate, and the plane of the cutting blade being perpendicular to the plane of the base.

[0016] Beneficial effects: The cutting blades are arranged vertically, facilitating cutting from the side after the anti-vibration mesh is lifted. As the anti-vibration mesh is lifted by the guide section and gradually rises from front to back along the guide surface and guide plate, the vertical arrangement of the cutting blades allows its cutting edge to cut the anti-vibration mesh at a defined cutting angle. The reasonable cutting direction helps improve cutting efficiency and quality.

[0017] In one alternative embodiment, the cutting blade is disposed on one side of the guide plate, and a shearing gap is formed between the cutting blade and the edge of the guide plate. The guide plate is used to cooperate with the cutting blade to provide shearing force when the cutting blade rotates.

[0018] Beneficial effects: The guide plate has both guiding and shearing functions. On one hand, the guide plate guides the anti-vibration mesh to the cutting position; on the other hand, the edge of the guide plate acts as a fixed blade, forming a shearing pair with the rotating cutting blade. Compared to cutting solely through friction from the rotating cutting blade, the shearing combination method results in greater cutting force, better cutting effect, and is less prone to high-temperature melting or burrs. Furthermore, since the guide plate acts as a fixed blade, there is no need for additional blades, simplifying the structure and reducing manufacturing costs.

[0019] In one alternative embodiment, the dismantling mechanism further includes a separation plate disposed on the side of the cutting plate away from the guide plate; the separation plate is inclined and extends gradually away from the cutting plate from the front end to the rear end of the base.

[0020] Beneficial effects: The separating plate gradually tilts away from the cutting plate from front to back, meaning that the rear end of the separating plate gradually moves away from the cutting edge area of ​​the cutting plate relative to its front end. When the cut anti-vibration mesh comes into contact with the separating plate during its forward movement, it is guided along the inclined surface of the separating plate and gradually deviates from the cutting plate, thereby achieving automatic separation from the cutting plate and preventing the cut anti-vibration mesh from becoming entangled on the cutting plate.

[0021] In one alternative embodiment, the dismantling mechanism further includes a reinforcing member, one end of which is connected to the guide plate and the other end of which is connected to the mounting base.

[0022] Beneficial effects: The guide plate bears a certain reaction force during the process of guiding the anti-vibration mesh and shearing with the cutting blade. Long-term use may cause the guide plate to deform or loosen. The reinforcement can transfer the force on the guide plate to the mounting base, where it is borne by both the mounting base and the base, thereby improving the rigidity and structural stability of the guide plate, extending its service life, and ensuring the accuracy of the shearing gap.

[0023] In one alternative embodiment, the bottom of the base is provided with a sliding element; And / or, the edges of the base are chamfered.

[0024] Beneficial effects: When the base moves along the outer wall of the fan, sliding friction occurs between the sliding component and the outer wall of the fan. By setting up the sliding component, the frictional force when the base moves on the outer wall of the fan can be reduced, the driving force requirement of the moving mechanism can be reduced, and the wear on the paint surface of the outer wall of the fan can be reduced.

[0025] In one alternative embodiment, the front end of the base gradually tapers along the width direction of the base to extend between the anti-flutter mesh and the outer wall of the fan.

[0026] Beneficial effects: During dismantling operations, the front end of the base needs to be inserted into the gap between the anti-vibration mesh and the outer wall of the fan. Because the width of the front end of the base gradually narrows, meaning its lateral dimension is smaller, it can more easily be inserted into narrow gaps, reducing the requirements for gap width and improving the success rate and convenience of the operation.

[0027] Secondly, the present invention also provides a dismantling mechanism, comprising: The base has a sliding support surface at its bottom for sliding contact with the outer wall of the fan; the front end of the base is provided with a guide part, which has an inclined guide surface. From the front end to the rear end of the base, the guide surface gradually increases in height, which is used to lift the anti-flutter net attached to the outer wall of the fan when the base moves along the outer wall of the fan. A cutting assembly, mounted on the base, is used to cut the anti-flutter net raised by the guide section.

[0028] Beneficial effects: This dismantling mechanism has the same structure as the dismantling mechanism in the anti-flutter net dismantling device used for wind turbines, and has the same beneficial effects, which will not be elaborated here. Attached Figure Description

[0032] In related technologies, the removal of flutter nets mainly relies on manual high-altitude operations, requiring workers to operate suspended hundreds of meters in the air using spider-like maneuvers or suspended platforms. However, this method has drawbacks such as high safety risks, difficulty in ensuring the personal safety of workers, low efficiency of manual operation, severe dependence on weather conditions, and short operating windows, directly affecting the progress of wind turbine grid connection.

[0033] The core objective of this research and development process was to address the technical pain points of high safety risks and low efficiency in high-altitude dismantling operations of flutter nets. To address these issues, the research team initially attempted to improve upon existing spider-man operation methods. While still having personnel suspended at height to the blade working surface, lightweight electric cutting tools were used to replace manual tools. The aim was to reduce the operational difficulty and physical exertion of the workers by leveraging the cutting capabilities of the electric tools, thereby improving dismantling efficiency.

[0034] However, in actual testing, this solution failed to fundamentally solve the inherent safety issues of working at heights. Workers still need to operate suspended hundreds of meters in the air, and the risk of falling from height remains. At the same time, workers lack a stable point of leverage while suspended, and even with electric cutting tools, it is still difficult to accurately control the cutting angle and force, and the problem of scratches on the blade surface has not been effectively improved.

[0035] Based on this, the inventors of this application have redesigned the anti-flutter net removal device for wind turbines. Because the base is equipped with a guide section with a gradually increasing guide surface, when the moving mechanism drives the removal mechanism to move along the outer wall of the wind turbine, the base moves along the outer wall, and the guide section smoothly lifts the anti-flutter net tightly attached to the blade surface and feeds it into the cutting component, which then cuts it off. Throughout the process, the operator only needs to control the moving mechanism from the ground via remote control to complete the high-altitude removal operation, eliminating the need for personnel to climb and thus eliminating the safety risk of falls from heights.

[0036] Furthermore, the bottom of the base is a sliding support surface that slides in contact with the outer wall of the wind turbine. Compared to manually suspending the tool, the sliding support surface can evenly distribute the weight of the dismantling mechanism, avoiding localized pressure concentration that could cause indentations or scratches on the blade surface. Combined with the guide section at the front of the base, the anti-flutter mesh can be lifted first, preventing the cutting components from directly contacting the blade surface and further ensuring the integrity of the blade paint and anti-corrosion layer.

[0037] Meanwhile, compared to the shortcomings of traditional manual high-altitude demolition methods, which rely on weather conditions, have short working windows, and are inefficient, this anti-flutter net demolition device uses a moving mechanism to drive the demolition mechanism to move and cut automatically. The demolition time for a single wind turbine can be shortened from several days to several hours, improving demolition efficiency and helping wind farms to connect to the grid for power generation in a timely or early manner.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0039] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0040] According to embodiments of the present invention, in one aspect, such as Figures 1 to 5 As shown, a flutter net removal device for wind turbines is provided. This device is mainly used to safely and efficiently remove the flutter nets temporarily tied to the outer wall of the wind turbine blades before the wind turbine is connected to the grid for power generation, so as to restore the streamlined aerodynamic shape of the blades and avoid secondary accidents caused by the binding straps being thrown out under high-speed rotation. The flutter net removal device includes a moving mechanism 1000 and a removal mechanism 2000.

[0041] Specifically, such as Figure 1 As shown, the moving mechanism 1000 is configured to be placed on the outer wall of the fan, and the moving mechanism 1000 is capable of moving on the outer wall of the fan.

[0042] Specifically, such as Figure 1 As shown, the dismantling mechanism 2000 is installed on the moving mechanism 1000, and the moving mechanism 1000 drives the dismantling mechanism 2000 to move together on the outer wall surface of the fan.

[0043] Furthermore, such as Figures 1 to 5 As shown, the demolition mechanism 2000 includes a base 100 and a cutting assembly 200. The base 100 serves as the supporting foundation for the entire demolition mechanism 2000, and its bottom is a sliding support surface for sliding contact with the outer wall surface of the wind turbine. That is, when the base 100 is in operation, it adheres to the blade surface through its bottom sliding support surface and moves synchronously with the moving mechanism 1000.

[0044] Specifically, such as Figure 2 As shown, the front end 110 of the base 100 is provided with a guide portion 130, which has an inclined guide surface. The guide surface gradually increases in height from the front end 110 to the rear end 120 of the base 100. That is, the gap between the guide surface and the outer wall of the fan is the smallest at the front end 110 of the base 100, and the guide surface gradually rises as it extends towards the rear end 120 of the base 100.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the cutting assembly 200 is mounted above the base 100, and is used to cut the anti-flutter net that is lifted by the guide 130. After the guide 130 lifts the anti-flutter net, the anti-flutter net is guided to the cutting assembly 200, where it is cut. The removed anti-flutter net then detaches from the blade under gravity.

[0046] This flutter net removal device features a guide section 130 with a gradually increasing guide surface on the base 100. When the moving mechanism 1000 drives the removal mechanism 2000 to move along the outer wall of the wind turbine, the base 100 moves along the outer wall of the wind turbine, and the guide section 130 smoothly lifts the flutter net that is tightly attached to the blade surface and sends it into the cutting component 200, which then cuts it off. Throughout the process, the operator only needs to control the moving mechanism 1000 from the ground via remote control to complete the high-altitude removal operation, eliminating the need for personnel to climb and thus eliminating the safety risk of falls from heights.

[0047] Furthermore, the bottom of the base 100 is a sliding support surface that slides in contact with the outer wall of the wind turbine. Compared to manually suspending the tool, the sliding support surface can evenly distribute the weight of the dismantling mechanism 2000, avoiding localized pressure concentration that could cause indentations or scratches on the blade surface. Combined with the guide section 130 at the front end 110 of the base 100, the anti-flutter net can be lifted first, preventing the cutting component 200 from directly contacting the blade surface, further ensuring the integrity of the blade paint and anti-corrosion layer.

[0048] Meanwhile, compared to the shortcomings of traditional manual high-altitude demolition methods, which rely on weather conditions, have short working windows, and are inefficient, this anti-flutter net demolition device uses a mobile mechanism 1000 to drive the demolition mechanism 2000 to move and cut automatically. The demolition time for a single wind turbine can be shortened from several days to several hours, improving demolition efficiency and helping wind farms to connect to the grid for power generation in a timely or early manner.

[0049] Specifically, the anti-flutter net removal device can be lifted by drone to the high-altitude wind turbine blades for operation, and then lifted away by drone after the operation is completed. The mobile mechanism 1000 can be equipped with a lifting point located at the center of gravity of the mobile mechanism 1000 to ensure that the device remains horizontal during lifting.

[0050] Specifically, the mobile mechanism 1000 can be a four-wheel drive vehicle, a tracked walking mechanism, or a multi-legged walking mechanism. In this embodiment, no specific limitation is placed on the type of the mobile mechanism 1000.

[0051] For example, the mobile mechanism 1000 can be a four-wheel drive vehicle that can move flexibly on the curved surface of the wind turbine blades through differential steering.

[0052] For example, the traveling wheel set of the mobile mechanism 1000 may be equipped with a shock-absorbing module to accommodate the complex three-dimensional curved surface deformation of the wind turbine blades.

[0053] For example, the guide portion 130 may be a wedge-shaped block integrally formed with the base 100, or it may be a separate component fixed to the front end 110 of the base 100 by fasteners.

[0054] For example, the flutter net is composed of flexible polymer foam blocks and high-strength safety straps, and the flutter net is fixed to the blade surface by the straps.

[0055] Specifically, the guide surface of the guide portion 130 can be a wedge-shaped inclined surface. When the moving mechanism 1000 drives the base 100 to move forward along the outer wall of the fan, the front end 110 of the guide portion 130 extends into the gap between the anti-flutter net and the outer wall of the fan. As the base 100 continues to move forward, the anti-flutter net is smoothly lifted along the gradually rising guide surface, thereby separating and lifting the anti-flutter net attached to the outer wall of the fan from the blade surface.

[0056] Specifically, the cutting assembly 200 can be a rotary blade cutting structure or a thermal cutting structure. In this embodiment, the type of the cutting assembly 200 is not specifically limited.

[0057] In one embodiment, such as Figures 1 to 5 As shown, a guide plate 140 is also provided on the base 100. The guide plate 140 is located behind the guide part 130. From the front end 110 to the rear end 120 of the base 100, the guide plate 140 is gradually raised. The guide plate 140 is used to guide the anti-vibration net raised by the guide part 130 to the cutting assembly 200.

[0058] A guide plate 140 is mounted on the base 100 and located behind the guide section 130. The guide section 130 and the guide plate 140 are arranged sequentially from the front end 110 to the rear end 120 of the base 100. After the guide section 130 lifts the anti-flutter net attached to the outer wall of the fan, the anti-flutter net continues to move backward along the guide surface of the guide section 130. At this time, the guide plate 140 receives the lifted anti-flutter net and further guides it to the cutting area of ​​the cutting assembly 200. The guide plate 140 is gradually raised from front to back, forming a continuous transition in height with the guide surface of the guide section 130. This ensures that the anti-flutter net enters the cutting assembly 200 with a smooth trajectory after being lifted, avoiding stacking or jamming of the anti-flutter net due to abrupt changes in height.

[0059] The guide plate 140 can organize and guide the anti-vibration net before it enters the cutting assembly 200, so that the anti-vibration net reaches the cutting position with a certain posture and path, ensuring the continuity and reliability of the dismantling process.

[0060] Furthermore, the gradually increasing height of the guide plate 140 is consistent with the tilt direction of the guide surface of the guide section 130, and together they form a conveying path that gradually rises from front to back. As the anti-vibration net moves along this path, the separation angle between it and the outer wall of the fan gradually increases with the increasing height, which is beneficial for the cutting assembly 200 to cut the anti-vibration net from below or the side, reducing the cutting difficulty.

[0061] Specifically, the guide plate 140 can be integrally formed with the base 100, or it can be fixedly connected to the base 100 by fasteners. In this embodiment, no specific limitation is made on the connection method between the guide plate 140 and the base 100.

[0062] For example, the guiding surface of the guide plate 140 can be a plane or a curved surface. In this embodiment, no specific limitation is made on the guiding surface of the guide plate 140.

[0063] In one embodiment, such as Figure 2 , Figure 4 and Figure 5 As shown, along the width direction of the base 100, the width of the guide portion 130 is greater than the width of the guide plate 140. That is, the dimension of the guide portion 130 in the width direction of the base 100 is greater than the dimension of the guide plate 140 in that direction. The guide portion 130 has a relatively wide picking range, while the guide plate 140 is relatively narrow.

[0064] Because the width of the guide section 130 is greater than the width of the guide plate 140, the guide section 130 can lift the anti-flutter net from the blade surface with a wider pickup surface, covering a wider working range and avoiding the failure to pick up part of the anti-flutter net due to positional deviation or excessive width. During the transition of the anti-flutter net from the guide section 130 to the guide plate 140, as the width gradually narrows, the anti-flutter net is gathered towards the center, so that the cutting assembly 200 can cut the gathered anti-flutter net at a determined cutting position, avoiding incomplete cutting or deviation of the cutting position due to excessive width or positional deviation of the anti-flutter net.

[0065] Furthermore, the transitional structure from wide to narrow formed by the width of the guide section 130 being greater than the width of the guide plate 140 allows the anti-vibration net to be guided towards the center during movement, which helps to regulate the shape of the anti-vibration net and ensure that it has a definite width and position when entering the cutting assembly 200, thereby guaranteeing the consistency and reliability of the cutting quality.

[0066] Specifically, the ratio of the width of the guide section 130 to the width of the guide plate 140 can be adaptively set according to the width of the anti-flutter net and the cutting range of the cutting assembly 200.

[0067] For example, the two sides of the guide portion 130 in the width direction can be extended outward relative to the two sides of the guide plate 140 in the width direction, forming a transitional form in which the width gradually decreases from the guide portion 130 to the guide plate 140.

[0068] In one embodiment, such as Figures 1 to 5As shown, the removal mechanism 2000 also includes a mounting base 300, which is connected to the base 100 at an angle. The mounting base 300 has a through hole 310 and a mounting hole 320. The cutting component 200 passes through the through hole 310 and is detachably connected to the mounting base 300 by fasteners passing through the mounting hole 320.

[0069] Specifically, the mounting base 300, serving as the support structure for the cutting assembly 200, is disposed on the base 100, and the mounting base 300 and the base 100 are connected at an angle. For example, the angle between the mounting base 300 and the base 100 can be approximately perpendicular. The mounting base 300 has a through hole 310 and a mounting hole 320. The through hole 310 is used for the cutting assembly 200 to pass through and be positioned, and the mounting hole 320 is used for fasteners to pass through and lock the cutting assembly 200 onto the mounting base 300. In other words, the cutting assembly 200 is first initially positioned by passing through the through hole 310, and then fixedly connected to the mounting base 300 by fasteners passing through the mounting hole 320, thereby achieving detachable installation.

[0070] The structure of the mounting base 300 makes the assembly of the cutting assembly 200 and the base 100 more convenient. The cutting assembly 200 is positioned through the through hole 310 and then locked in place with fasteners through the mounting hole 320. The separation of positioning and locking functions helps improve assembly accuracy and efficiency. At the same time, the detachable connection method facilitates the maintenance, replacement and repair of the cutting assembly 200, reducing the later operating costs.

[0071] Furthermore, the mounting base 300 is connected to the base 100 at an angle, so that the cutting component 200 mounted on the mounting base 300 has a definite orientation relative to the base 100, thereby ensuring that the cutting component 200 can cut the anti-flutter mesh in a preset posture, improving the accuracy and consistency of the cutting.

[0072] For example, the shape of the through hole 310 can be adapted to the outer contour of the cutting assembly 200 to further improve positioning accuracy.

[0073] For example, the mounting hole 320 can be a threaded hole, and the fastener can be a screw or bolt, achieving a detachable connection through threaded engagement. Of course, the mounting hole 320 can also be a smooth hole, with the fastener engaging a nut for locking.

[0074] Specifically, the mounting base 300 can be integrally formed with the base 100, or it can be fixedly connected to the base 100 by welding or fasteners. In this embodiment, no specific limitation is made on the connection method between the mounting base 300 and the base 100.

[0075] Specifically, the mounting base 300 may also be provided with a plurality of mounting holes 320, which are arranged around the through hole 310 to enhance the connection strength between the cutting assembly 200 and the mounting base 300.

[0076] For example, the mounting base 300 may also have heat dissipation holes or weight reduction holes to reduce weight or improve heat dissipation.

[0077] In one embodiment, combined Figure 1 and Figure 2 As shown, the cutting assembly 200 includes a drive component and a cutting blade 210. The drive component is mounted on the mounting base 300, and the cutting blade 210 is connected to the output end of the drive component. The drive component drives the cutting blade 210 to rotate at high speed around its axis. The plane of the cutting blade 210 is perpendicular to the plane of the base 100, meaning the cutting blade 210 is arranged approximately vertically on the base 100. Since the bottom of the base 100 is in contact with the outer wall of the fan when the base 100 is placed on it, the plane of the cutting blade 210 is perpendicular to the plane of the base 100, meaning the cutting blade 210 is arranged perpendicular to the outer wall of the fan.

[0078] The cutting blade 210 is arranged vertically, which facilitates cutting from the side after the anti-vibration mesh is lifted. As the anti-vibration mesh is lifted by the guide part 130 and gradually raised from front to back along the guide surface and guide plate 140, the vertical arrangement of the cutting blade 210 allows its cutting edge to cut the anti-vibration mesh at a certain cutting angle. The reasonable cutting direction is conducive to improving cutting efficiency and quality.

[0079] Furthermore, the plane of the cutting blade 210 is perpendicular to the plane of the base 100, which gives the cutting blade 210 a definite posture relative to the base 100. This helps to ensure the relative positional accuracy between the cutting edge of the cutting blade 210 and other components (such as the guide plate 140 described later), thereby ensuring the consistency of the cutting effect.

[0080] For example, the driving component can be a motor, the output shaft of which is directly connected to the cutting blade 210 or connected via a reducer.

[0081] For example, the cutting blade 210 can be a disc blade with a cutting edge on its circumferential edge. The axis of rotation of the cutting blade 210 is parallel to the sliding support surface of the base 100.

[0082] Specifically, the fact that the plane of the cutting blade 210 is perpendicular to the plane of the base 100 can be understood as the plane of rotation of the cutting blade 210 being perpendicular to the sliding support surface of the base 100. In other words, the axis of rotation of the cutting blade 210 is parallel to the sliding support surface of the base 100.

[0083] For example, the cutting disc 210 can be made of tool steel or cemented carbide to ensure that it has sufficient hardness and wear resistance to meet the cutting requirements of high-strength safety straps.

[0084] In one embodiment, combined Figures 1 to 5 As shown, the cutting blade 210 is arranged on one side of the guide plate 140, with the cutting edge of the cutting blade 210 adjacent to the edge of the guide plate 140, forming a shearing gap between them. When the anti-vibration mesh is guided by the guide plate 140 to the position of the cutting blade 210, the anti-vibration mesh enters the shearing gap between the cutting blade 210 and the guide plate 140. The driving component drives the cutting blade 210 to rotate, generating a shearing force similar to scissors between the cutting edge of the cutting blade 210 and the edge of the guide plate 140, cutting the anti-vibration mesh located in the shearing gap.

[0085] The guide plate 140 serves a dual function of guiding and shearing. On one hand, the guide plate 140 guides the anti-vibration mesh to the cutting position; on the other hand, the edge of the guide plate 140 acts as a fixed blade (i.e., a stationary blade), forming a shearing pair together with the rotating cutting blade 210 (i.e., a moving blade). Compared to the method of cutting solely by the rotational friction of the cutting blade 210, the shearing combination method results in greater cutting force, better cutting effect, and is less prone to high-temperature melting or burrs. Furthermore, since the guide plate 140 acts as a stationary blade, no additional blade is required, simplifying the structure and reducing manufacturing costs.

[0086] Furthermore, a shearing gap is formed between the cutting blade 210 and the edge of the guide plate 140, rather than the cutting blade 210 directly contacting the guide plate 140. This ensures the effective transmission of shearing force and avoids excessive wear or jamming caused by direct contact between the cutting blade 210 and the guide plate 140, thereby improving the reliability and service life of the cutting assembly 200.

[0087] Specifically, the size of the shearing gap can be adapted to the thickness and material of the anti-vibration mesh, ensuring that the cutting blade 210 can cut the anti-vibration mesh by engaging with the edge of the guide plate 140 when rotating.

[0088] For example, the edge of the guide plate 140 may be provided with a cutting edge to enhance the shearing effect.

[0089] Specifically, the shearing action between the cutting blade 210 and the guide plate 140 is similar to the working principle of scissors. The cutting blade 210 is equivalent to one blade of the scissors, and the edge of the guide plate 140 is equivalent to the other blade. When the two move in an alternating manner, they generate a shearing force that cuts the anti-vibration mesh located between them.

[0090] In one embodiment, such as Figures 1 to 5As shown, the dismantling mechanism 2000 also includes a separation plate 400, which is disposed on the side of the cutting plate 210 away from the guide plate 140. That is, the guide plate 140 and the separation plate 400 are respectively located on both sides of the cutting plate 210, and the three are arranged sequentially along the width direction of the base 100. After the anti-vibration mesh is cut by the cutting plate 210, the cut part is located on the side of the cutting plate 210 away from the guide plate 140. If this part continues to move with the cutting plate 210, it is very easy to get tangled on the cutting plate 210 or the output shaft of the drive component, resulting in jamming or even damage to the equipment.

[0091] The separating plate 400 extends gradually at an angle away from the cutting plate 210 from front to back. That is, the rear end 120 of the separating plate 400 gradually moves away from the cutting edge area of ​​the cutting plate 210 relative to its front end 110. When the cut anti-vibration mesh comes into contact with the separating plate 400 during its forward movement, it is guided along the inclined surface of the separating plate 400 and gradually deviates from the cutting plate 210, thereby achieving automatic separation from the cutting plate 210 and preventing the cut anti-vibration mesh from getting tangled on the cutting plate 210.

[0092] Furthermore, the separation plate 400 is tilted and gradually moves away from the extension direction of the cutting plate 210, which is in line with the movement direction of the anti-vibration mesh after it is cut. This allows the cut anti-vibration mesh to be smoothly guided out of the cutting area, ensuring the continuity and reliability of the cutting operation.

[0093] Specifically, the separator 400 has a simple structure, can achieve separation without an additional power source, and is low in cost and reliable in effect.

[0094] For example, the separator 400 can be a sheet metal part, which is bent to form an inclined guide surface.

[0095] For example, the separator 400 may be integrally formed with the base 100 or may be fixedly connected to the base 100 by fasteners. Alternatively, the separator 400 may be integrally formed with the mounting base 300 or may be fixedly connected to the mounting base 300 by fasteners.

[0096] Specifically, the tilt angle of the separating plate 400 away from the cutting plate 210 can be adaptively set according to factors such as the material, thickness and cutting speed of the anti-vibration mesh, to ensure that the cut anti-vibration mesh can be smoothly exported.

[0097] For example, the end of the separating plate 400 near the cutting plate 210 may be provided with an arc transition to avoid scratching the anti-flutter mesh or creating additional resistance.

[0098] In one embodiment, such as Figure 2 and Figure 3As shown, the dismantling mechanism 2000 also includes a reinforcing member 500, wherein one end of the reinforcing member 500 is connected to the guide plate 140 and the other end is connected to the mounting base 300.

[0099] The guide plate 140 experiences a certain reaction force during the process of guiding the anti-vibration mesh and shearing in conjunction with the cutting blade 210. Prolonged use may cause the guide plate 140 to deform or loosen. The reinforcing member 500 transfers the force on the guide plate 140 to the mounting base 300, where it is jointly borne by the mounting base 300 and the base 100. This improves the rigidity and structural stability of the guide plate 140, extends its service life, and ensures the accuracy of the shearing gap.

[0100] Furthermore, the reinforcing member 500 connects the guide plate 140 and the mounting base 300, so that the guide plate 140 maintains the relative positional accuracy with the cutting blade 210 during operation, avoiding the increase or decrease of the shearing gap due to the deformation or displacement of the guide plate 140 under force, thereby ensuring the consistency and reliability of the shearing effect.

[0101] For example, the reinforcing member 500 may be a reinforcing rib plate with its surface perpendicular to the base 100 to provide support strength in the direction of force on the guide plate 140.

[0102] For example, one reinforcement 500 may be provided, or multiple reinforcements may be provided at intervals along the width direction of the base 100 to improve the balance of support.

[0103] For example, the cross-sectional shape of the stiffener 500 can be rectangular, L-shaped, T-shaped or I-shaped, etc., to improve its bending stiffness.

[0104] In one embodiment, such as Figures 2 to 5 As shown, the bottom of the base 100 is provided with a slider; and / or, the edges of the base 100 are surrounded by chamfers.

[0105] As the base 100 moves along the outer wall of the fan, sliding friction occurs between the sliding component and the outer wall of the fan. By setting the sliding component, the frictional force of the base 100 when it moves on the outer wall of the fan can be reduced, the driving force requirement of the moving mechanism 1000 can be reduced, and the wear on the paint surface of the outer wall of the fan can be reduced.

[0106] The base 100 has a chamfered edge around its perimeter. The outer peripheral edge of the base 100 is chamfered to form a rounded transition or a beveled transition. When the base 100 moves on the outer wall of the wind turbine, the chamfered edge prevents sharp edges from scratching the paint or anti-corrosion layer on the blade surface, while also preventing stress concentration from causing cracking or chipping of the base 100 edge. For example, the chamfer can be a rounded chamfer or a C-shaped chamfer.

[0107] Specifically, the sliding element and the chamfer can be installed independently or simultaneously, and both provide protection for the outer wall of the fan from different perspectives. The sliding element reduces wear by decreasing the coefficient of friction, while the chamfer eliminates sharp edges to prevent scratches, together ensuring the integrity of the blade surface.

[0108] Specifically, the bottom of the base 100 is provided with a sliding member, which is disposed on the sliding support surface of the base 100 for direct contact with and relative sliding of the outer wall surface of the fan. For example, the sliding member can be a sliding plate, a sliding block, or a wear-resistant coating.

[0109] For example, the slider can be mounted on the sliding support surface of the base 100 by means of embedding, bonding or fastening.

[0110] For example, the sliding element can be made of wear-resistant plastic (such as polytetrafluoroethylene, nylon, etc.) or wear-resistant metal material to reduce frictional damage to the outer wall of the fan while ensuring wear resistance.

[0111] Specifically, when the base 100 has a chamfer on its edge, the chamfer can be set around the entire outer periphery of the base 100, or it can be set only on the front end 110 and / or side edge of the base 100.

[0112] For example, the radius or bevel size of the chamfer can be adapted to the material and thickness of the base 100 to ensure that it can provide protection without affecting the strength and rigidity of the base 100.

[0113] In one embodiment, such as Figures 2 to 5 As shown, along the width direction of the base 100, the front end 110 of the base 100 gradually tapers, so that the front end 110 of the base 100 is generally in a tapered wedge or pointed shape, so as to extend into the space between the anti-flutter net and the outer wall of the fan.

[0114] During dismantling operations, the front end 110 of the base 100 needs to be inserted into the gap between the anti-vibration mesh and the outer wall of the fan. Because the width of the front end 110 of the base 100 gradually narrows, that is, the lateral dimension of the front end 110 of the base 100 is small, it can be more easily inserted into narrow gaps, reducing the requirements for the gap width and improving the success rate and convenience of the operation.

[0115] The gradually tapering structure of the front end 110 of the base 100 cooperates with the inclined guide surface of the guide part 130. The tapering in the width direction makes it easier for the front end 110 of the base 100 to enter the gap, and the inclined guide surface in the height direction makes it easier for the front end 110 of the base 100 to lift the anti-flutter net from the blade surface. The two work together to achieve reliable pickup of the anti-flutter net.

[0116] Specifically, the gradual narrowing of the front end 110 of the base 100 can be a linear narrowing in the width direction or an arc-shaped narrowing.

[0117] For example, the end of the constricted portion of the front end 110 of the base 100 may be formed into a pointed tip or an arc head to further reduce resistance when inserting into the gap and avoid scratching the blade surface.

[0118] For example, as the front end 110 of the base 100 gradually shrinks, the width of the guide portion 130 also changes adaptively, that is, the width of the guide portion 130 also shrinks at the front end 110 of the base 100, so as to ensure that the guide surface of the guide portion 130 can cover the entire width range of the front end 110 of the base 100, and ensure that the anti-vibration net is subjected to uniform force during the lifting process.

[0119] According to an embodiment of the present invention, on the other hand, such as Figures 1 to 5 As shown, a dismantling mechanism is also provided, including a base 100 and a cutting assembly 200.

[0120] Specifically, such as Figures 1 to 5 As shown, the bottom of the base 100 is a sliding support surface for sliding contact with the outer wall surface of the fan; wherein, the front end 110 of the base 100 is provided with a guide part 130, the guide part 130 has an inclined guide surface, and the guide surface gradually increases from the front end 110 to the rear end 120 of the base 100, which is used to lift the anti-flutter net attached to the outer wall surface of the fan when the base 100 moves along the outer wall surface of the fan.

[0121] Specifically, such as Figures 1 to 5 As shown, the cutting assembly 200 is mounted on the base 100 and is used to cut the anti-flutter net raised by the guide 130.

[0122] This dismantling mechanism has the same structure and the same beneficial effect as the dismantling mechanism 2000 in the anti-flutter net dismantling device used for wind turbines, and will not be described in detail here.
