Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation devices, and in particular to a blade-sweeping resistance reinforcement device for a wind turbine tower and wind power generation equipment. Background Art

[0002] In recent years, with the continuous development of clean energy technologies, wind power generation, as a clean energy source, has experienced rapid growth. Larger and higher-capacity wind turbines have become the mainstream development trend. The continuous increase in unit capacity and the ever-expanding wind swept area have driven the evolution of wind turbine blades to longer sizes, resulting in significantly increased blade flexibility and consequently increased deformation. At the same time, site conditions and cost constraints have limited the ability to significantly increase tower heights. This has led to a continuous decrease in the safe distance between the blade tip and the ground and tower, resulting in an increasing frequency of safety incidents such as blade sweeps. These incidents not only cause severe damage to the blades themselves, but also place significant additional stress on the tower due to the unbalanced loads caused by blade impacts. In extreme cases, they can even cause tower collapses, posing a significant threat to the safe operation of wind power projects and increasing safety risks.

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

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] In one aspect, the present invention provides a blade sweep resistance reinforcement device for a wind turbine tower, comprising:

[0007] A housing, the housing being attached to the inner wall of the wind turbine tower and being arranged in the swept area of ​​the wind turbine blades; a receiving chamber being arranged in the housing;

[0008] a filling layer, the filling layer being filled in the accommodating chamber;

[0009] An adsorption member is provided on a side of the shell body that contacts the inner wall of the wind turbine tower, and the adsorption member is configured to fix the shell body on the inner wall of the wind turbine tower.

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

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

[0012] As an optional technical solution for an anti-blade sweep tower reinforcement device for a wind turbine tower, 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 shell facing the inner wall of the wind turbine tower.

[0013] As an optional technical solution for a blade-sweeping-resistant tower reinforcement device for a wind turbine tower, the embedded magnetic blocks are provided in plurality, and the plurality of embedded magnetic blocks are evenly distributed in a ring shape on the shell.

[0014] As an optional technical solution for an anti-blade sweep tower reinforcement device for a wind turbine tower, the anti-blade sweep tower reinforcement device for a wind turbine tower also includes a connecting piece, a connecting portion is also provided on the shell, a connecting hole is provided on the inner wall of the wind turbine tower, and one end of the connecting piece passes through the connecting portion and is detachably connected to the connecting hole.

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

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

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

[0018] As an optional technical solution for a 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:

[0020] The present invention provides a blade-sweep-resistant tower reinforcement device for a wind turbine tower. The device comprises a housing, a filling layer, and an adsorbent. The housing is attached to the inner wall of the wind turbine tower and positioned in the swept area of ​​the wind turbine blades. A chamber is disposed within the housing.

[0021] In the above, a filling layer is provided within the housing, and the housing is located in the swept area of ​​the wind turbine blades. When the wind turbine blades collide with the wind turbine tower during rotation, i.e., sweeping the tower, the impact force on the wind turbine tower is transmitted to the housing and the filling layer within the housing. The filling layer disperses the impact force, evenly distributing the localized impact force generated by the wind turbine blades sweeping the tower to the housing and the wind turbine tower, thereby preventing stress concentration and other problems caused by localized excessive force on the wind turbine tower. An adsorbent is provided on the side of the housing that contacts the inner wall of the wind turbine tower, securely securing the housing to the inner wall of the wind turbine tower. This prevents the housing from shifting or loosening within the wind turbine tower due to vibration, impact, and other factors, ensuring that the housing is always in the optimal protective position. This effectively improves the wind turbine tower's impact resistance in the swept area of ​​the wind turbine blades, effectively resisting the impact force generated by the wind turbine blades sweeping the tower, preventing accidents such as tower collapse caused by localized stress concentration, reducing safety hazards, extending the service life of the wind turbine tower, and ensuring the safe and stable operation of the wind turbine.

[0022] The present invention also provides a wind power generation equipment, which improves the impact resistance of the wind turbine tower in the wind turbine blade sweeping area, can effectively resist the impact force generated by the wind turbine blades sweeping the tower, avoid the occurrence of wind turbine tower collapse accidents due to local stress concentration, and reduce safety hazards.

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

[0037] Example 1

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

[0039] like Figure 1-Figure 3 As shown, the anti-blade sweep tower reinforcement device for a wind turbine tower mainly includes a shell 10, a filling layer 20, and an adsorbent 30. The shell 10 is attached to the inner wall of the wind turbine tower 100 and is located in the sweeping area of ​​the wind turbine blades 200. The shell 10 is provided with a receiving chamber. The filling layer 20 is filled in the receiving chamber. The adsorbent 30 is provided on the side of the shell 10 that contacts the inner wall of the wind turbine tower 100 and is configured to fix the shell 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 in the housing 10, and the housing 10 is located in the swept area of ​​the wind turbine blades 200. When the wind turbine blades 200 collide with the wind turbine tower 100 during rotation, that is, when a tower sweep occurs, the impact force on the wind turbine tower 100 can be transmitted to the housing 10 and the filling layer 20 in the housing 10. The filling layer 20 disperses the impact force, and the local impact force generated by the wind turbine blades 200 sweeping the tower is evenly distributed to the housing 10 and the wind turbine tower 100, thereby avoiding the wind turbine tower 100 from experiencing stress concentration problems due to excessive local force. The adsorption member 30 is provided on the side of the housing 10 that contacts the inner wall of the wind turbine tower 100, and the housing 10 is firmly fixed to the inner wall of the wind turbine tower 100. This can prevent the housing 10 from shifting or loosening due to factors such as vibration and impact in the wind turbine tower 100, ensuring that the housing 10 is always in the best 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 withstand 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 a high-strength mortar, cement, quartz sand, and silica fume are mixed in a ratio of 1:1.5:0.2, and polycarboxylic acid water reducer (3% dosage) is added and stirred into a fluid mortar. The mortar is poured into the accommodating chamber through a grouting pump, and an exhaust hole is provided on the top of the shell 10 to ensure that there are no bubbles.

[0043] When the filling layer 20 is polyurethane foam, the density is 40kg / m 3 The rigid polyurethane foam is injected from the top of the accommodating chamber through a high-pressure spray gun. The polyurethane foam expands and fills the accommodating chamber, and solidifies into shape after 2 hours.

[0044] High-strength mortar has high compressive strength (≥80MPa) and can convert the impact load borne by the shell 10 into uniform pressure and transmit it to the wind turbine tower 100, thereby preventing the wind turbine tower 100 from being locally over-pressurized and improving the wind turbine tower 100's ability to resist deformation. Polyurethane foam is lightweight and can reduce the additional load on the wind turbine tower 100. At the same time, its elastic modulus is low and it can absorb part of the impact energy through its own deformation (such as when the wind turbine blades 200 slightly sweep the tower), making it suitable for scenarios that are sensitive to the load on the wind turbine tower 100. The above two 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 by processing glass fiber reinforced composite (GFRP) or carbon fiber reinforced composite (CFRP).

[0046] Specifically, when the housing 10 is made of a 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. Furthermore, the high strength of the glass fiber reinforced composite material provides reliable impact resistance for the wind turbine tower 100. This effectively resists the impact force generated by the wind turbine blades 200 sweeping across the tower, protecting the wind turbine tower 100 from damage and ensuring the normal operation of the wind turbine.

[0047] When the shell 10 is made of carbon fiber reinforced composite material, its strength and modulus are higher, and it has excellent fatigue resistance and corrosion resistance. In some areas where the impact resistance of the wind turbine tower 100 is extremely high, such as large-scale wind power generation equipment with long blades, fast sweeping speeds, and large wind loads, the shell 10 made of carbon fiber reinforced composite material can more effectively resist the impact of frequent blade sweeps on the tower, thereby increasing the service life of the wind turbine tower 100. In addition, the corrosion resistance of carbon fiber reinforced composite material enables it to function stably and for a long time in harsh environmental conditions (such as coastal, offshore, chemical pollution, etc.), resist the erosion of the shell 10 by various corrosive media, and improve its reliability and durability.

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

[0049] Specifically, the housing 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, the sub-shells can be easily transported to the installation location and spliced ​​one by one. The annular structure formed by splicing multiple sub-shells can better fit the inner wall of the wind turbine tower 100, ensuring a tight connection between the housing 10 and the inner wall of the wind turbine tower 100 and improving the reinforcement effect.

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

[0051] In some optional embodiments, the housing 10 is formed by splicing four identical sub-shells, and each sub-shell is in the shape of a quarter frustum.

[0052] Furthermore, structural adhesive is applied to two opposing sides of the subshells, bonding two adjacent subshells together. The use of structural adhesive strengthens the connection between adjacent subshells, allowing the multiple subshells to form a single unit after assembly, thereby increasing the structural rigidity and load-bearing capacity of the housing 10. The bonding effect of the structural adhesive prevents localized weakness in the wind turbine tower's anti-blade sweep reinforcement device caused by loose subshell assembly, thereby ensuring the integrity and reliability of the wind turbine tower's anti-blade sweep reinforcement device.

[0053] like Figure 2-Figure 3 As shown, in this embodiment, the adsorption member 30 is an embedded magnetic block, and the outer surface of the embedded magnetic block is flush with the surface of the side 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 adsorbed to the inner wall of the wind turbine tower 100 by magnetic force, and there is no need to drill or weld on the wind turbine tower 100, which avoids destroying the integrity of the original steel structure and causing damage to the wind turbine tower 100. The outer surface of the embedded magnetic block is flush with the surface of the shell 10, ensuring that the shell 10 and the inner wall of the wind turbine tower 100 fit tightly together without any gaps, thus avoiding local deformation or vibration of the shell 10 due to the gap when the wind turbine tower 100 is subjected to impact force, and ensuring the continuity of the load transfer path. In addition, the embedded magnetic block is embedded in the groove of the shell 10, which can avoid direct contact with the filling layer 20, reduce the corrosion or extrusion of the embedded magnetic block by the filling layer 20, and extend 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 5 cm and a thickness of 8 mm.

[0056] Optionally, the embedded magnetic blocks in this embodiment are provided in a plurality, and the plurality of embedded magnetic blocks are evenly distributed in a circular shape on the shell 10. The even distribution of the multiple embedded magnetic blocks in a circular shape can avoid local warping of the shell 10 due to insufficient magnetic force of a single embedded magnetic block; the uniform spacing of the multiple embedded magnetic blocks can ensure that the adsorption force between each point of the shell 10 and the inner wall of the wind turbine tower 100 is consistent. When the wind turbine blades 200 sweep the tower, the impact load is evenly transmitted to each embedded magnetic block in a circular direction, and then dispersed to the inner wall of the wind turbine tower 100, preventing the shell 10 from falling off due to insufficient local adsorption force. Compared with the centralized arrangement of multiple embedded magnetic blocks, the even distribution method makes the shell 10 less likely to deviate during long-term use and has better stability.

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

[0058] The anti-blade sweep reinforcement device for the wind tower is installed in the sweeping area of ​​the wind blade 200, and directly strengthens the impact point when the wind blade 200 sweeps the tower; it improves the impact resistance of the wind tower 100 in this area, effectively resists the impact force generated by the wind blade 200 sweeping the tower, and prevents the local stress concentration of the wind tower 100 from causing the tower collapse accident.

[0059] Optionally, the wind turbine tower 100 in this embodiment is made of stainless steel, with a bottom diameter of 6m and a top diameter of 3m; the wind turbine blades 200 are arranged as three blades, and each wind turbine blade 200 is 80m long. The anti-blade sweep tower reinforcement device for the wind turbine tower is installed on the inner wall of the wind turbine tower 100 and at a distance of 30mm-35m from the top of the wind turbine tower 100. This position corresponds to the maximum diameter area swept by the wind turbine blades 200 (such as Figure 1 (shown by the dotted circle in the figure).

[0060] Please continue to refer to Figure 1 The wind power generation equipment further includes a support base 300 and anchor bolts. The support base 300 is connected to the bottom of the wind turbine tower 100. 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, evenly transferring the vertical load borne by the wind turbine tower 100 to the concrete foundation. The anchor bolts penetrate 2 meters into the concrete foundation, leveraging the concrete foundation's wrapping force to transfer horizontal impact loads deep into the concrete foundation. This prevents the bottom of the wind turbine tower 100 from sliding or tilting, thereby improving the stability and reliability of the wind turbine.

[0062] For example, the support base 300 is welded with Q355 steel plates with a thickness of 50 mm, the anchor bolts are high-strength bolts with a diameter of 40 mm, 24 anchor bolts are arranged and evenly distributed in a ring, and the distance between two adjacent anchor bolts is 1 m. 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 2 m), and the other end is fixed to the support base 300 by a nut.

[0063] Example 2

[0064] This embodiment provides an anti-blade sweep tower reinforcement device for a wind turbine tower. The main difference from the first embodiment is that the anti-blade sweep tower reinforcement device for a wind turbine tower in this embodiment also includes a connecting piece (not shown in the figure), a connecting portion is also provided on the shell 10, and a connecting hole is provided on the inner wall of the wind turbine tower 100. One end of the connecting piece passes through the connecting portion and is detachably connected to the connecting hole.

[0065] By providing a connection portion on the housing 10, providing a connection hole on the inner wall of the wind turbine tower 100, and utilizing a connector to detachably connect the housing 10 to the inner wall of the wind turbine tower 100, the stability of the connection between the housing 10 and the wind turbine tower 100 is further enhanced. This connection method provides additional connection force, which, together with the magnetic attraction of the embedded magnetic block, ensures that the housing 10 is securely and reliably mounted on the inner wall of the wind turbine tower 100. Even in the event of significant impact or prolonged vibration, the housing 10 is prevented from shifting or falling off, thereby improving the reliability and stability of the wind turbine.

[0066] The connection between the connecting piece and the connecting hole is a detachable connection, which is convenient for maintenance and replacement of the shell 10 or the filling layer 20 at a later time.

[0067] The connection part cooperates with the connection hole on the inner wall of the wind turbine tower 100 to ensure 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 humid environments such as coastal areas reduce the magnetic attraction of the embedded magnetic block.

[0068] For example, the connector is an M12 stainless steel bolt, the connecting portion is a through-hole on the flange of the housing 10, and the connection hole on the inner wall of the wind tower 100 is a threaded hole. During installation, the housing 10 is initially secured using the embedded magnetic blocks. The M12 stainless steel bolt is then threaded through the through-hole on the flange of the housing 10 and into the threaded hole of the wind tower 100. One connector is placed between every two embedded magnetic blocks.

[0069] The remaining structures of the anti-blade sweep tower reinforcement device for the wind turbine tower in this embodiment are the same as those in the first embodiment and will not be described in detail here.
