[0043] Wind turbines generally consist of a tower and a nacelle. The nacelle, located at the top of the tower, is responsible for converting wind energy into electrical energy. The tower, as the main structural component of the wind turbine, supports and connects the various assemblies. Towers typically come in two forms: pure steel towers and steel-concrete hybrid towers (hereinafter referred to as hybrid towers). Steel towers are usually composed of multiple tower units connected by flanges and bolts. Hybrid towers typically consist of multiple precast concrete sections, a top steel-concrete transition section, and an upper steel section. The precast concrete sections are assembled using adhesive materials and formed into a whole by tensioning steel strands. The top steel-concrete transition section is connected to the steel sections using anchor bolts.

[0044] To facilitate maintenance and equipment placement, the tower's interior is typically hollow, resulting in an opening on the top connecting surface. This opening remains open until the nacelle is installed. During construction, rain and snow can directly penetrate the tower, causing corrosion of the steel strand anchor heads or steel walls, and potentially leading to moisture damage and short circuits in the electrical cabinet at the base of the tower, thus affecting the overall lifespan and operational safety of the unit.

[0045] To reduce the impact of wind and snow on the internal components of the tower, related technologies typically include rainproof devices on the top connection surfaces of the tower, thereby reducing the possibility of wind and snow entering the tower and protecting the safety of the internal facilities.

[0046] To install the rainproof device on the top connection surface, the common practice is to build a rainproof frame on the top connection surface of the tower by welding, and then lay a rainproof tarpaulin on the outside of the frame to form the rainproof device. This construction method is time-consuming, material-costing, and poses significant fire hazards due to high-altitude welding operations. Furthermore, the heat generated by welding can damage the anti-corrosion layer of the tower, increasing the subsequent installation costs of the duct unit.

[0047] To address the aforementioned problems, this application proposes a rainproof device comprising a mounting base, a rainproof tarpaulin, and a connector. The mounting base is positioned on the top connection surface and located on the opening. The rainproof tarpaulin is mounted on the mounting base and covers the opening. The connector is positioned on the side of the mounting base away from the top connection surface and has a connection hole for the installation of anchor bolts from the wind turbine tower to secure the connector and the mounting base to the top connection surface.

[0048] This application supports the rainproof tarpaulin by installing a base frame and uses connectors to work with the existing anchors on the wind turbine tower to fix the base frame to the top connection surface of the tower without welding and in a detachable manner. This achieves lightweighting of the rainproof device, reduces the amount of material used in the rainproof device, lowers the layout cost of the rainproof device, reduces the impact of the installation of the rainproof device on the structure of the tower itself, and improves the assembly efficiency of the rainproof device.

[0049] The rainproof device provided in this application will now be described in detail with reference to the accompanying drawings.

[0050] Please refer to Figures 1 to 3 The rainproof device 100 includes a mounting base 1, a rainproof tarpaulin 2, and connectors 3. The mounting base 1 serves as the supporting frame of the rainproof device 100, used for installing and supporting the rainproof tarpaulin 2. The mounting base 1 is located on the top connecting surface 210 of the tower 200, and the top connecting surface 210 of the tower 200 can be... Figure 1 The steel surface shown can also be as follows: Figure 2 The concrete surface shown is not limited in this application.

[0051] The connector 3 is used to fix the mounting base 1 to the top connecting surface 210 of the tower 200. The connector 3 can be a split clamp, a single-hole pressure plate, or a toothed anti-slip saddle-shaped pressure seat. For example, the connector 3 is a double-hole pad with two connecting holes. The anchor bolt 300 of the tower 200 can pass through the connecting holes to fix the connector 3 and the mounting base 1 to the top connecting surface 210 of the tower 200.

[0052] The number of connectors 3 can be one, two, or more, and this application does not limit this. For example, the rainproof device 100 includes 28 connectors 3, which are arranged circumferentially on the top connecting surface 210 of the tower 200. At least some of the connectors 3 are connected to the mounting base 1 to provide fixation for the mounting base 1.

[0053] In some embodiments, the connector 3 includes a first connecting part and a second connecting part connected to each other. The first connecting part contacts the mounting base 1, and a connecting hole is provided in the first connecting part. One end of the second connecting part is connected to the first connecting part, and the other end is used to extend towards the side of the first connecting part away from the top connecting surface 210. The second connecting part is bent in the same direction from the edge of the first connecting part to form a vertical plate. The vertical plate and the first connecting part form an "L" shaped cross section. The vertical plate forms a reinforcing rib in the radial direction of the anchor bolt 300, which significantly improves the bending and torsional stiffness of the connector 3, prevents the pad from warping under wind load or wire rope tension, and ensures the long-term stability of the rainproof device 100.

[0054] In addition to reinforcing the structure of the connector 3, the second connecting part can also be reused to install the rainproof tarpaulin 2. Specifically, in some embodiments, the second connecting part is provided with an installation hole. The rainproof device 100 also includes a first fastener. One end of the first fastener is connected to the rainproof tarpaulin 2, and the other end is connected to the installation hole. In this way, while retaining the reinforcing effect of the second connecting part on the connector 3, the installation of the rainproof tarpaulin 2 is realized, eliminating the need for other installation structures, reducing the number of parts in the rainproof device 100, reducing the layout cost of the rainproof device 100, and improving the assembly efficiency of the rainproof device 100.

[0055] The first fastener can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle; this application does not limit this.

[0056] It is understood that in other possible embodiments of this application, the rainproof tarpaulin 2 can also be connected to the anchor bolts 300 of the mounting base 1 or the tower 200, and this application does not limit this.

[0057] To support the rainproof tarpaulin 2, in some embodiments, the mounting base 1 includes a plurality of first mounting rods 11 and a plurality of second mounting rods 12. The number of first mounting rods 11 and second mounting rods 12 can be two, three, or four, and this application does not limit this. For example, the mounting base 1 includes four first mounting rods 11 and four second mounting rods 12.

[0058] Multiple first mounting rods 11 are spaced apart along a first direction on the top connecting surface 210, and multiple second mounting rods 12 are spaced apart along a second direction on the side of the first mounting rods 11 opposite to the top connecting surface 210. The second direction and the first direction are intersecting directions. This intersection can be 30°, 60°, or 90°, and this application does not limit this. Exemplarily, the second direction is perpendicular to the first direction. The connector 3 contacts the first mounting rods 11 and the second mounting rods 12 to install the first mounting rods 11 and the second mounting rods 12 onto the top connecting surface 210, thereby forming a grid support platform on the top connecting surface 210. This grid serves as both the planar support skeleton of the rainproof tarpaulin 2 and, through the intersection nodes, evenly distributes the external load on the rainproof device 100 to each connecting plate, providing a stable foundation for the subsequent tensioning of the rainproof tarpaulin 2.

[0059] The first mounting rod 11 and the second mounting rod 12 can be connected using standard scaffolding connecting fasteners or similar fasteners, or they can be connected by other methods such as binding. In some embodiments, the rainproof device 100 also includes a second fastener, which can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle. This application does not limit this.

[0060] The second fastener is connected between the first mounting rod 11 and the second mounting rod 12 to detachably connect the first mounting rod 11 and the second mounting rod 12 at the intersection point. This not only improves the assembly and disassembly speed of the first mounting rod 11 and the second mounting rod 12, but also avoids damage to the tower 200 caused by welding open flames, reduces the material usage of the rainproof device 100, lowers the layout cost of the rainproof device 100, reduces the impact of the installation of the rainproof device 100 on the structure of the tower 200 itself, and improves the assembly efficiency of the rainproof device 100.

[0061] In some embodiments, the rainproof device 100 further includes a third mounting rod 13. The third mounting rod 13 is connected to the first mounting rod 11 and the second mounting rod 12. The third mounting rod 13 extends along a third direction, which intersects with the first and second directions in three directions. This intersection can be 30°, 60°, or 90°, and this application does not impose any limitations on this. For example, the third direction is perpendicular to the first and second directions.

[0062] The third mounting rod 13 contacts the rainproof tarpaulin 2 to stretch the rainproof tarpaulin 2 into a cover with a drainage slope, thereby expanding the rainproof tarpaulin 2 into a dome shape that is high in the middle and low around the edges, so that rain and snow can slide naturally down the slope to the outside of the tower 200, avoiding water accumulation on the waterproof tarpaulin.

[0063] Understandably, in other possible implementations, the third mounting rod 13 may also be connected only to the first mounting rod 11 or only to the second mounting rod 12, and this application does not limit this.

[0064] The third mounting rod 13 and the first mounting rod 11 are connected to the second mounting rod 12 using standard scaffolding connecting fasteners or similar fasteners, or by binding or other methods. In some embodiments, the rainproof device 100 also includes a third fastener, which can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle. This application does not limit this.

[0065] The third fastener is connected between the third mounting rod 13 and the first mounting rod 11 or the third mounting rod 13 and the second mounting rod 12, so as to detachably connect the third mounting rod 13, the first mounting rod 11 and the second mounting rod 12 at the intersection point. In this way, the disassembly and assembly speed of the first mounting rod 11 and the second mounting rod 12 can be improved, the damage to the tower 200 caused by welding open flame can be avoided, the material usage of the rainproof device 100 can be reduced, the layout cost of the rainproof device 100 can be reduced, the impact of the installation of the rainproof device 100 on the structure of the tower 200 itself can be reduced, and the assembly efficiency of the rainproof device 100 can be improved.

[0066] The number of third mounting rods 13 can be one, two, or more; this application does not limit this. In some embodiments, the mounting base 1 also includes multiple third mounting rods 13 and multiple fourth mounting rods 14. The multiple third mounting rods 13 extend along a third direction and are connected to the mounting base 1. Each third mounting rod 13 has a first end 131 and a second end 132 arranged opposite each other along a third direction. The fourth mounting rods 14 are connected between the first ends 131 of each adjacent third mounting rod 13, thus forming a top closed loop frame between the first ends 131 of the third mounting rods 13, improving the support strength of the third mounting rods 13 for the waterproof tarpaulin. At the same time, this loop frame and the third mounting rods 13 constitute an integral ridge truss, providing a continuous tension edge for the rainproof tarpaulin 2, uniformly transmitting external loads, avoiding local instability of a single rod, thereby improving the support stability of the waterproof tarpaulin and the overall structural strength.

[0067] The fourth mounting rod 14 and the third mounting rod 13 are connected by standard scaffolding connecting fasteners or similar fasteners, or by other means such as binding. In some embodiments, the rainproof device 100 also includes a fourth fastener, which can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle. This application does not limit this.

[0068] The fourth fastener is connected between the fourth mounting rod 14 and the third mounting rod 13 to detachably connect the fourth mounting rod 14 and the third mounting rod 13 at the intersection point. This not only improves the speed of assembling and disassembling the fourth mounting rod 14 and the third mounting rod 13, but also avoids damage to the tower 200 caused by open welding flames, reduces the material usage of the rainproof device 100, lowers the layout cost of the rainproof device 100, reduces the impact of the installation of the rainproof device 100 on the structure of the tower 200 itself, and improves the assembly efficiency of the rainproof device 100.

[0069] In some embodiments, the mounting base 1 further includes a fifth mounting rod 15, which is connected between the second ends 132 of each adjacent third mounting rod 13. The fifth mounting rod 15 is used to form a top closed loop frame between the first ends 131 of the third mounting rods 13, thereby improving the support strength of the third mounting rods 13 for the waterproof tarpaulin.

[0070] The fifth mounting rod 15 and the third mounting rod 13 can be welded, connected using standard scaffolding connecting fasteners or similar fasteners, or connected by other methods such as binding. In some embodiments, the rainproof device 100 also includes a fifth fastener, which can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle. This application does not limit this.

[0071] The fifth fastener is connected between the fifth mounting rod 15 and the third mounting rod 13 to detachably connect the fifth mounting rod 15 and the third mounting rod 13 at the intersection point. This not only improves the assembly and disassembly speed of the fifth mounting rod 15 and the third mounting rod 13, but also avoids damage to the tower 200 caused by open welding flames, reduces the material usage of the rainproof device 100, lowers the layout cost of the rainproof device 100, reduces the impact of the installation of the rainproof device 100 on the structure of the tower 200 itself, and improves the assembly efficiency of the rainproof device 100.

[0072] In some embodiments, the rainproof device 100 further includes a diagonal bar 16, which is disposed between the third mounting rod 13 and the first mounting rod 11. The diagonal bar 16 is used to form a triangular stabilizing system together with the third mounting rod 13 and the first mounting rod 11, so as to increase the lateral stiffness of the top cover, reduce the cantilever bending moment of the third mounting rod 13, and improve the stability of the rainproof device 100.

[0073] The diagonal brace 16 and the third mounting rod 13 can be connected using standard scaffolding connecting couplers or similar fasteners, or they can be connected by other methods such as binding. In some embodiments, the rainproof device 100 also includes a sixth fastener, which can be a spring hook, a shackle, a quick-connect safety hook, a wire rope clamp, or a spiral buckle. This application does not limit this.

[0074] The sixth fastener is connected between the diagonal brace 16 and the third mounting rod 13 to detachably connect the diagonal brace 16 and the third mounting rod 13 at the intersection point. This not only improves the speed of assembling and disassembling the diagonal brace 16 and the third mounting rod 13, but also avoids damage to the tower 200 caused by open welding flames, reduces the material usage of the rainproof device 100, reduces the layout cost of the rainproof device 100, reduces the impact of the installation of the rainproof device 100 on the structure of the tower 200 itself, and improves the assembly efficiency of the rainproof device 100.

[0075] Understandably, the diagonal brace 16 can also be connected to the first end 131 of the third mounting rod 13, or to the second end 132 of the third mounting rod 13. In some embodiments, the first mounting rod 11 and the second mounting rod 12 constitute a base. The base has a first end face and a second end face that are arranged opposite each other along a third direction. The first end 131 is located on one side of the first end face of the base, and the second end 132 is located on one side of the second end face of the base. The diagonal brace 16 is disposed between the second end 132 and the first connecting rod, which can effectively reduce the cantilever length of the third mounting rod 13, increase the torque that the root of the third mounting rod 13 can withstand, and improve the stability of the third mounting rod 13 for supporting the waterproof canopy.

[0076] The materials of the first mounting rod 11, the second mounting rod 12, the third mounting rod 13, the fourth mounting rod 14, the fifth mounting rod 15, and the diagonal rod 16 can be steel, aluminum, or iron. Preferably, standard scaffolding steel pipes that are readily available on the market can be used, but this application does not impose any restrictions on this.

[0077] The rainproof tarpaulin 2 is used to cover the top flange opening 220 of the tower 200 to prevent wind and snow from directly entering the tower. The material of the rainproof tarpaulin 2 can be polypropylene, polyvinyl chloride, or other waterproof flexible materials. This application does not limit this.

[0078] The edge of the rainproof tarpaulin 2 is provided with multiple connecting rings. The material of the connecting rings can be steel, iron, or other rigid materials, and this application does not limit this. One end of the first buckle is connected to the mounting hole of the second connecting part, and the other end is connected to the connecting ring, thereby fixing the rainproof tarpaulin 2 to the top connecting surface 210.

[0079] In some embodiments, the rainproof tarpaulin includes multiple connecting rings, and the rainproof device includes multiple connectors 3, multiple first fasteners, and connecting ropes; the mounting holes of the multiple connecting rings and the multiple connectors are arranged one-to-one; each first fastener is connected between each connecting ring and each mounting hole; the connecting rope is threaded through the connecting rings, mounting holes, and fasteners, so as to form a continuous circumferential band around the rainproof tarpaulin, so that the edge of the rainproof tarpaulin 2 is evenly stressed and tightly attached to the outline of the frame, increasing the tension of the rainproof tarpaulin cover and preventing the rainproof tarpaulin from loosening or accumulating water.

[0080] The following will provide a detailed description of the assembly method of the rainproof device provided in this application.
