Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a wind turbine tower anti-blade sweeping reinforcement device and wind power generation equipment. Background Technology

[0002] In recent years, with the continuous development of clean energy technologies, wind power generation, as one of the clean energy sources, has achieved rapid development. Larger scale and higher capacity have become the mainstream development trend for wind turbine generators. The continuous increase in single-unit capacity and the continuous expansion of swept area have driven wind turbine blades to evolve towards longer dimensions, resulting in a significant increase in blade flexibility and deformation. Simultaneously, limited by site conditions and cost control, tower height cannot be increased significantly at the same time, leading to a continuous reduction in the safe distance between the blade tip and the ground and between the tower, and a year-on-year increase in the frequency of safety accidents such as blade-tower sweep. These accidents not only cause severe damage to the blades themselves, but also cause the tower to bear enormous additional stress due to the load imbalance generated by the blade impact, even leading to tower collapse in extreme cases, posing a significant threat to the safe operation of wind power projects and increasing safety hazards.

[0003] Therefore, there is an urgent need to design a wind turbine tower anti-blade sweeping reinforcement device and wind power generation equipment to solve the above technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wind turbine tower anti-blade sweeping reinforcement device and wind power generation equipment, which improves the impact resistance of the wind turbine tower in the area swept by the wind turbine blades, extends its service life, and reduces safety hazards.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, the present invention provides a wind turbine tower anti-blade sweeping reinforcement device, comprising:

[0007] The housing is attached to the inner wall of the wind turbine tower and is located in the sweeping area of ​​the wind turbine blades; the housing has a receiving chamber inside.

[0008] A filling layer that fills the receiving cavity;

[0009] An adsorption element is disposed on the side of the housing that contacts the inner wall of the wind turbine tower, and the adsorption element is configured to fix the housing to the inner wall of the wind turbine tower.

[0010] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the shell includes multiple sub-shells, which are spliced ​​together to form an annular structure that is adapted to the inner wall of the wind turbine tower.

[0011] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, structural adhesive is provided on two opposite sides of the sub-shell, and adjacent sub-shells are bonded together by the structural adhesive.

[0012] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the adsorption component is an embedded magnetic block, and the outer surface of the embedded magnetic block is flush with the side surface of the housing facing the inner wall of the wind turbine tower.

[0013] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the embedded magnetic blocks are configured in multiple ways, and the multiple embedded magnetic blocks are evenly distributed in a ring on the housing.

[0014] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the wind turbine tower anti-blade sweeping reinforcement device also includes a connector, the housing is also provided with a connecting part, the inner wall of the wind turbine tower is provided with a connecting hole, and one end of the connector passes through the connecting part and is detachably connected to the connecting hole.

[0015] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the filling layer is high-strength mortar or polyurethane foam.

[0016] As an optional technical solution for a wind turbine tower anti-blade sweeping reinforcement device, the shell is a glass fiber reinforced composite or a carbon fiber reinforced composite.

[0017] On the other hand, the present invention provides a wind power generation device, including a wind turbine tower, wind turbine blades, and the anti-blade sweeping reinforcement device for the wind turbine tower as described in any of the above optional technical solutions. The wind turbine blades are installed on the top of the wind turbine tower, and the anti-blade sweeping reinforcement device for the wind turbine tower is installed on the sweeping area of ​​the wind turbine blades on the inner wall of the wind turbine tower.

[0018] As an optional technical solution for wind power generation equipment, the wind power generation equipment also includes a support base and anchor bolts. The support base is connected to the bottom of the wind turbine tower, and one end of the anchor bolt passes through the support base and is connected to the concrete foundation.

[0019] The beneficial effects of the present invention include at least the following:

[0020] This invention provides a reinforcement device for wind turbine towers against blade sweeping, comprising a housing, a filling layer, and an adsorption component. The housing is attached to the inner wall of the wind turbine tower and positioned at the area where the wind turbine blades sweep; a receiving chamber is provided within the housing. The filling layer fills the receiving chamber. The adsorption component is located on the side of the housing that contacts the inner wall of the wind turbine tower, and is configured to fix the housing to the inner wall of the wind turbine tower.

[0021] As described above, a filling layer is installed inside the casing, and the casing is located in the sweeping area of ​​the wind turbine blades. When the wind turbine blades collide with the wind turbine tower during rotation, i.e., when tower sweep occurs, the impact force on the wind turbine tower can be transmitted to the casing and the filling layer inside the casing. The filling layer disperses the impact force, evenly distributing the localized impact force generated by the wind turbine blade sweeping onto the casing and the wind turbine tower, avoiding stress concentration problems caused by excessive local stress on the wind turbine tower. The adsorption component is located on the side of the casing that contacts the inner wall of the wind turbine tower, firmly fixing the casing to the inner wall of the wind turbine tower. This prevents the casing from shifting or loosening due to vibration, impact, or other factors within the wind turbine tower, ensuring that the casing is always in the optimal protective position. This effectively improves the impact resistance of the wind turbine tower in the wind turbine blade sweeping area, resists the impact force generated by the wind turbine blade sweeping, prevents tower collapse and other accidents caused by localized stress concentration, reduces safety hazards, extends the service life of the wind turbine tower, and ensures the safe and stable operation of the wind power generation equipment.

[0022] The present invention also provides a wind power generation device that improves the impact resistance of the wind turbine tower in the area swept by the wind turbine blades, effectively resists the impact force generated by the wind turbine blades sweeping the tower, avoids tower collapse accidents caused by local stress concentration, and reduces safety hazards.

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Example 1

[0038] This embodiment provides a wind turbine tower anti-blade sweeping reinforcement device and wind power generation equipment, which improves the impact resistance of the wind turbine tower in the area swept by the wind turbine blades, extends its service life, and reduces safety hazards.

[0039] like Figures 1-3 As shown, the anti-blade sweeping reinforcement device for wind turbine towers mainly includes a housing 10, a filling layer 20, and an adsorption component 30. The housing 10 is attached to the inner wall of the wind turbine tower 100 and is positioned at the sweeping area of ​​the wind turbine blades 200; a receiving chamber is provided inside the housing 10. The filling layer 20 fills the receiving chamber. The adsorption component 30 is located on the side of the housing 10 that contacts the inner wall of the wind turbine tower 100, and is configured to fix the housing 10 to the inner wall of the wind turbine tower 100.

[0040] Based on the above design, in this embodiment, a filling layer 20 is provided inside the housing 10, and the housing 10 is located in the sweeping area of ​​the wind turbine blades 200. When the wind turbine blades 200 collide with the wind turbine tower 100 during rotation, i.e., when a sweeping incident occurs, the impact force on the wind turbine tower 100 can be transmitted to the housing 10 and the filling layer 20 inside the housing 10. The filling layer 20 disperses the impact force, evenly distributing the local impact force generated by the sweeping of the wind turbine blades 200 onto the housing 10 and the wind turbine tower 100, thus avoiding stress concentration and other problems caused by excessive local stress on the wind turbine tower 100. The adsorption component 30 is provided on the side of the housing 10 that contacts the inner wall of the wind turbine tower 100, firmly fixing the housing 10 to the inner wall of the wind turbine tower 100. This can prevent the housing 10 from shifting or loosening inside the wind turbine tower 100 due to vibration, impact, or other factors, ensuring that the housing 10 is always in the optimal protective position. It effectively improves the impact resistance of the wind turbine tower 100 in the area swept by the wind turbine blades 200, can resist the impact force generated by the wind turbine blades 200 sweeping the tower, prevents the wind turbine tower 100 from collapsing due to local stress concentration, reduces safety hazards, extends the service life of the wind turbine tower 100, and ensures the safe and stable operation of wind power generation equipment.

[0041] Optionally, the filling layer 20 in this embodiment is high-strength mortar or polyurethane foam.

[0042] Specifically, when the filling layer 20 is high-strength mortar, cement, quartz sand, and silica fume are mixed in a ratio of 1:1.5:0.2, and polycarboxylate superplasticizer (3% admixture) is added. The mixture is stirred into a fluid mortar and injected into the accommodating chamber through a grouting pump. The top of the shell 10 is provided with an air vent to ensure that there are no air bubbles.

[0043] When the filler layer 20 is polyurethane foam, a density of 40 kg / m³ is selected. 3 Rigid polyurethane foam is injected from the top of the accommodating chamber through a high-pressure spray gun. After the polyurethane foam expands and fills the accommodating chamber, it solidifies and takes shape after 2 hours.

[0044] High-strength mortar possesses high compressive strength (≥80MPa), which can convert the impact load borne by the shell 10 into uniform pressure transmitted to the wind turbine tower 100, preventing excessive local pressure on the wind turbine tower 100 and improving its deformation resistance. Polyurethane foam is lightweight, reducing the additional load on the wind turbine tower 100. Simultaneously, its low modulus of elasticity allows it to absorb some impact energy through its own deformation (such as when the wind turbine blades 200 slightly sweep the tower), making it suitable for scenarios where the wind turbine tower 100 is sensitive to loads. Both of these filling layers 20 can be flexibly selected according to the actual operating environment of the wind power generation equipment.

[0045] Optionally, the housing 10 is a glass fiber reinforced composite or a carbon fiber reinforced composite. In other words, the housing 10 can be made of glass fiber reinforced composite (GFRP) or carbon fiber reinforced composite (CFRP).

[0046] Specifically, when the shell 10 is made of glass fiber reinforced composite material, this material is lightweight and high-strength. Its low density does not significantly increase the weight of the wind turbine tower 100. At the same time, the high strength of the glass fiber reinforced composite material provides reliable impact resistance for the wind turbine tower 100. Under the impact force generated by the wind turbine blades 200 sweeping across the tower, it can effectively resist the impact, protect the wind turbine tower 100 from damage, and ensure the normal operation of the wind power generation equipment.

[0047] When the shell 10 is made of carbon fiber reinforced composite material, its strength and modulus are higher, exhibiting excellent fatigue resistance and corrosion resistance. In areas where the impact resistance of the wind turbine tower 100 is extremely high, such as large wind power generation equipment with long blades, high sweeping speeds, and large wind loads, the shell 10 made of carbon fiber reinforced composite material can more effectively resist frequent blade sweeping impacts, thus improving the service life of the wind turbine tower 100. Furthermore, the corrosion resistance of carbon fiber reinforced composite material allows it to function stably for a long time under harsh environmental conditions (such as coastal, marine, and chemically polluted environments), resisting the erosion of the shell 10 by various corrosive media, thereby improving its reliability and durability.

[0048] In some alternative embodiments, the housing 10 includes a plurality of sub-shells, which are spliced ​​together to form an annular structure adapted to the inner wall of the wind turbine tower 100.

[0049] Specifically, the outer shell 10 is divided into multiple sub-shells, which facilitates transportation and installation, especially when the internal space of the wind turbine tower 100 is limited. This allows the sub-shells to be easily transported to the installation location one by one and then assembled. The ring structure formed by assembling multiple sub-shells can better fit against the inner wall of the wind turbine tower 100, ensuring a tight connection between the outer shell 10 and the inner wall of the wind turbine tower 100, and improving the reinforcement effect.

[0050] For example, the sub-shell can be installed using installation methods such as scaffolding, which are common in the art.

[0051] In some alternative embodiments, the housing 10 is composed of four identical sub-shells joined together, each sub-shell being a quarter-truncated cone shape.

[0052] Furthermore, structural adhesive is applied to the two opposite sides of the sub-shell, and adjacent sub-shells are bonded together using this adhesive. The use of structural adhesive enhances the connection strength between adjacent sub-shells, allowing multiple sub-shells to be joined into a single unit, thus improving the structural rigidity and load-bearing capacity of the shell 10. The bonding effect of the structural adhesive prevents localized weaknesses in the anti-blade-sweeping reinforcement device for wind turbine towers caused by loose sub-shell connections, ensuring the overall integrity and reliability of the device.

[0053] like Figures 2-3 As shown, in this embodiment, the adsorption element 30 is an embedded magnetic block, and the outer surface of the embedded magnetic block is flush with the side surface of the housing 10 facing the inner wall of the wind turbine tower 100. The housing 10 is provided with a groove, and the embedded magnetic block is embedded in the groove.

[0054] The embedded magnetic block is magnetically attached to the inner wall of the wind turbine tower 100, eliminating the need for drilling or welding on the tower 100 and preventing damage to the original steel structure. The outer surface of the embedded magnetic block is flush with the surface of the housing 10, ensuring a tight, gap-free fit between the housing 10 and the inner wall of the tower 100. This prevents localized deformation or vibration of the housing 100 due to gaps when subjected to impact forces, ensuring a continuous load transmission path. Furthermore, the embedded magnetic block is recessed within the housing 10, avoiding direct contact with the filling layer 20 and reducing corrosion or compression from the filling layer 20, thus extending the service life of the adsorption component 30.

[0055] Optionally, the embedded magnetic block in this embodiment is a neodymium iron boron magnet with a diameter of 5cm and a thickness of 8mm.

[0056] Optionally, in this embodiment, multiple embedded magnetic blocks are provided, and these multiple embedded magnetic blocks are evenly distributed in a ring on the housing 10. The evenly distributed ring of multiple embedded magnetic blocks avoids localized warping of the housing 10 due to insufficient magnetic force of a single embedded magnetic block. The uniform spacing between the multiple embedded magnetic blocks ensures consistent adsorption force between all points of the housing 10 and the inner wall of the wind turbine tower 100. When the wind turbine blades 200 sweep the tower, the impact load is evenly transmitted along the ring direction to each embedded magnetic block, and then dispersed to the inner wall of the wind turbine tower 100, preventing the housing 10 from detaching due to insufficient local adsorption force. Compared to a centralized arrangement of multiple embedded magnetic blocks, the evenly distributed method makes the housing 10 less prone to displacement during long-term use, resulting in better stability.

[0057] like Figure 1As shown, this embodiment also provides a wind power generation device, which includes a wind turbine tower 100, wind turbine blades 200, and the aforementioned anti-blade sweeping reinforcement device for the wind turbine tower. The wind turbine blades 200 are installed on the top of the wind turbine tower 100, and the anti-blade sweeping reinforcement device for the wind turbine tower is installed on the sweeping area of ​​the wind turbine blades 200 on the inner wall of the wind turbine tower 100.

[0058] The anti-blade sweeping reinforcement device for wind turbine towers is installed in the sweeping area of ​​the wind turbine blades 200, directly strengthening the impact point when the wind turbine blades 200 sweep the tower; it improves the impact resistance of the wind turbine tower 100 in this area, effectively resists the impact force generated by the wind turbine blades 200 sweeping the tower, and prevents the wind turbine tower 100 from collapsing due to local stress concentration.

[0059] Optionally, in this embodiment, the wind turbine tower 100 is made of stainless steel, with a bottom diameter of 6m and a top diameter of 3m; the wind turbine blades 200 are configured as three-bladed, each blade being 80m in length. An anti-blade-sweeping reinforcement device for the wind turbine tower is installed on the inner wall of the wind turbine tower 100 at a distance of 30mm-35mm from the top of the wind turbine tower 100. This position corresponds to the area of ​​maximum diameter swept by the wind turbine blades 200 (e.g., ...). Figure 1 (as shown by the dashed circle in the image).

[0060] Please continue to refer to this. Figure 1 The wind power generation equipment also includes a support base 300 and anchor bolts. The support base 300 is connected to the bottom of the wind turbine tower 100, and one end of the anchor bolt passes through the support base 300 and is connected to the concrete foundation.

[0061] Specifically, the support base 300 is connected to the bottom of the wind turbine tower 100 via a flange, increasing the contact area between the wind turbine tower 100 and the concrete foundation, and evenly transferring the vertical load borne by the wind turbine tower 100 to the concrete foundation. Anchor bolts penetrate 2m into the concrete foundation, utilizing the enveloping force of the concrete foundation to transfer horizontal impact loads deep into the concrete foundation, preventing the bottom of the wind turbine tower 100 from sliding or tilting, and improving the stability and reliability of the wind power generation equipment.

[0062] For example, the support base 300 is welded from a Q355 steel plate with a thickness of 50mm. The anchor bolts are high-strength bolts with a diameter of 40mm. There are 24 anchor bolts, which are evenly distributed in a ring. The distance between two adjacent anchor bolts is 1m. One end of the anchor bolt passes through the bolt hole of the support base 300 and is buried in the concrete foundation (buried to a depth of 2m). The other end is fixed to the support base 300 by a nut.

[0063] Example 2

[0064] This embodiment provides a wind turbine tower anti-blade sweeping reinforcement device, which differs from the first embodiment in that: the wind turbine tower anti-blade sweeping reinforcement device in this embodiment also includes a connector (not shown in the figure), the housing 10 is also provided with a connecting part, the inner wall of the wind turbine tower 100 is provided with a connecting hole, and one end of the connector passes through the connecting part and is detachably connected to the connecting hole.

[0065] By providing a connecting part on the housing 10 and a connecting hole on the inner wall of the wind turbine tower 100, the housing 10 and the inner wall of the wind turbine tower 100 are detachably connected using connectors, further enhancing the connection stability between the housing 10 and the wind turbine tower 100. This connection method provides additional connection force, which, together with the magnetic attraction force of the embedded magnetic block, ensures that the housing 10 is firmly and reliably installed on the inner wall of the wind turbine tower 100. Even under large impact forces or long-term vibration, it can prevent the housing 10 from shifting or falling off, improving the reliability and stability of the wind power generation equipment.

[0066] The connection between the connector and the connection hole is detachable, which facilitates the maintenance and replacement of the housing 10 or the filling layer 20 in the future.

[0067] The connection between the connecting part and the connecting hole on the inner wall of the wind turbine tower 100 ensures that the shell 10 does not undergo lateral displacement during impact, further improving the stability of the overall structure. It is especially suitable for scenarios where the magnetic attraction of the embedded magnetic block decreases due to humid environments such as coastal areas.

[0068] For example, the connector is an M12 stainless steel bolt, the connection part is a through hole on the flange of the housing 10, and the connection hole on the inner wall of the wind turbine tower 100 is a threaded hole. During installation, the housing 10 is first initially fixed by the embedded magnetic blocks, and then the M12 stainless steel bolt is screwed into the threaded hole of the wind turbine tower 100 through the through hole on the flange of the housing 10. One connector is set between every two embedded magnetic blocks.

[0069] The remaining structures of the anti-blade sweeping reinforcement device for wind turbine towers in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0070] Obviously, the above description is merely a preferred embodiment of the present invention and the technical principles employed.
