Description

Technical Field

[0001] This application belongs to the field of wind power generation technology, specifically relating to an installation structure for a wind turbine de-icing system. Background Technology

[0002] A wind turbine, also known simply as a wind power generator, is an electrical device that converts wind energy into mechanical energy, and then mechanical energy into electrical energy. A wind turbine uses wind power to rotate its blades, and a speed increaser further accelerates the rotation, thus generating electricity. In current technology, in areas with low temperatures, high humidity, and high altitudes, the blades of wind turbines are prone to icing, which can affect their normal operation. Therefore, some wind turbines are typically equipped with an internal thermal de-icing system to remove ice from the blades.

[0003] However, existing air-heated de-icing systems typically require workers to install them into the wind turbine themselves, and wind turbines are rarely designed with an installation location or space for air-heated de-icing systems, which increases the difficulty of installation. Utility Model Content

[0004] The technical problem to be solved by this application is to provide an installation structure for a fan de-icing system, so as to solve the technical problem of the high installation difficulty of the existing gas-heat de-icing system.

[0005] Based on the above objectives, this application provides an installation structure for a wind turbine de-icing system, used for installing a de-icing system on a wind turbine generator. The installation structure includes:

[0006] Support, first mounting plate and anti-torsion bracket;

[0007] The support is installed inside the blade root of the wind turbine to install an anti-torsion bracket.

[0008] The first mounting plate is connected to the outside of the hub near the blade root. The first mounting plate is used to install the de-icing hub control cabinet, which is equipped with the de-icing control system.

[0009] Optionally, a second mounting plate is provided on the side of the hub away from the first mounting plate. The second mounting plate is used to mount the main engine pitch control cabinet. The first mounting plate and the second mounting plate are fixedly connected to one end of the hub by the same set of bolts and nuts.

[0010] Optionally, the first mounting plate and the second mounting plate have the same structure and size, and are arranged side by side.

[0011] Optionally, the first mounting plate is trapezoidal in shape and can be mounted on the wheel hub to avoid most of the wheel hub manhole.

[0012] Optionally, the first mounting plate has clearance holes for passing cables and / or pipes.

[0013] Optionally, the first mounting plate has multiple mounting holes near its edge for threading bolts to mount the first mounting plate onto the wheel hub.

[0014] Optionally, the first mounting plate has equipment connection holes for bolts to be inserted to mount the de-icing hub control cabinet.

[0015] Optionally, two supports are provided along the radial direction of the blade root, and the two ends of the anti-torsion bracket are respectively connected to the two supports.

[0016] Optionally, the distance between the support and the outer port of the wheel hub is 400mm-460mm.

[0017] Optionally, the connection method between the anti-torsion bracket and the support includes at least one of adhesive bonding, welding, and bolt connection.

[0018] Optionally, the connection method between the support and the blade root includes at least one of adhesive bonding, welding, and bolting.

[0019] The beneficial effects of this application are as follows: The installation structure of the wind turbine de-icing system provided by this application is fixed to the outside of the hub near the blade root via a first mounting plate. This plate is used to centrally install the de-icing hub control cabinet, integrating the de-icing control system into the cabinet and simplifying the wiring layout. It solves the problem of existing wind turbines lacking dedicated installation locations for de-icing systems.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0025] In a wind turbine, three blades are evenly mounted circumferentially on the hub. The blade roots 90 are connected to the hub 30 via pitch bearings 80. A blade root manhole baffle 100 is also provided on the blade root 90. The manhole baffle 100 usually has a through hole in its center, facilitating maintenance personnel to enter the blade for inspection, maintenance, and repair. In existing technologies, in areas with low temperatures, high humidity, and high altitudes, wind turbine blades are prone to icing, affecting the normal operation of the wind turbine. Therefore, some wind turbines typically have an internal air-thermal de-icing system to remove ice from the blades. However, existing air-thermal de-icing systems usually require manual installation by personnel inside the wind turbine, and wind turbines are rarely designed with an installation location and space for air-thermal de-icing systems, which increases the installation difficulty. To solve the above technical problems, this application provides the following technical solution:

[0026] like Figure 1-3 As shown, this application provides an installation structure for a wind turbine de-icing system, used for installing a de-icing system for a wind turbine generator. The installation structure includes: a support 10, a first mounting plate 20, and an anti-torsion bracket 40; the support 10 is disposed within the blade root 90 of the wind turbine generator to install the anti-torsion bracket 40; the first mounting plate 20 is connected to the outer side of the hub 30 near the blade root 90, and the first mounting plate 20 is used to install the hub control cabinet 60, which contains a de-icing control system.

[0027] Compared with existing technologies, the installation structure of the wind turbine de-icing system provided in this application embodiment is fixed to the outer side of the hub 30 near the blade root 90 by a first mounting plate 20. This is used to centrally install the de-icing hub control cabinet 60, integrating the de-icing control system into the cabinet and simplifying the wiring layout. This solves the problem of existing wind turbines lacking dedicated installation positions for de-icing systems. Through standardized support and mounting plate design, modifications to the original wind turbine structure are reduced, installation difficulty is lowered, and the location of the de-icing hub control cabinet 60 is rationally allocated to avoid equipment congestion and facilitate future maintenance. Furthermore, the support 10 provides a fixed fulcrum for the anti-torsion bracket 40, ensuring its stability within the hub 30. The anti-torsion bracket 40 enhances the system's anti-torsion capability, preventing equipment displacement or damage due to blade rotation.

[0028] In one possible implementation, a second mounting plate 50 is provided on the side of the hub 30 opposite to the first mounting plate 20. The second mounting plate 50 is used to mount the main engine pitch control cabinet 70. The first mounting plate 20 and the second mounting plate 50 are fixedly connected to one end of the hub 30 by the same set of bolts and nuts. In this way, the shared bolts reduce the number of holes in the hub 30, simplify the installation steps, reduce the risk of damage to the hub 30 structure, and improve installation efficiency.

[0029] In one possible implementation, the first mounting plate 20 and the second mounting plate 50 have the same structure and dimensions and are arranged side by side. This standardized design reduces the number of parts, simplifies production and inventory management, lowers manufacturing costs, improves installation consistency, and avoids human error.

[0030] In one possible implementation, the first mounting plate 20 is trapezoidal in shape and is mounted on the wheel hub 30 to avoid most of the wheel hub manhole 310. Thus, the trapezoidal structure adapts to the wheel hub shape, avoids obstructing the maintenance passage (wheel hub manhole 310), and improves maintainability.

[0031] In one possible implementation, the first mounting plate 20 has clearance holes 210 for cable and / or conduit routing. The clearance holes 210 are designed to enable centralized cable management, reducing space requirements and installation conflicts.

[0032] In one possible implementation, the first mounting plate 20 has a plurality of mounting holes 220 near its edge for threading bolts to mount the first mounting plate 20 onto the hub 30.

[0033] In one possible implementation, the first mounting plate 20 has equipment connection holes 230 for bolting the de-icing hub control cabinet 60.

[0034] In one possible implementation, two supports 10 are provided radially along the blade root, and the two ends of the anti-torsion bracket 40 are respectively connected to the two supports 10. In this way, the symmetrically distributed supports 10 form stable support points, distributing the force on the anti-torsion bracket 40. This enhances the seismic and torsional resistance of the anti-torsion bracket 40 and prevents fatigue fracture caused by single-point support.

[0035] In one possible implementation, the distance between the support 10 and the outer port of the wheel hub 30 is 400mm-460mm. This distance range ensures that the anti-torsion bracket 40 will not interfere with the de-icing wheel hub control cabinet 60 after installation, leaving sufficient installation space for it, while avoiding excessive occupation of the wheel hub 30 port and ensuring the overall structural compactness.

[0036] In one possible implementation, the connection between the anti-torsion bracket 40 and the support 10 includes at least one of adhesive bonding, welding, and bolting. Among them, adhesive bonding can use epoxy resin adhesive, which does not require drilling and simplifies the installation process; welding provides a high-rigidity connection; and bolting facilitates disassembly and maintenance, flexibly adapting to different working conditions and balancing structural strength and construction convenience.

[0037] In one possible implementation, the connection between the support 10 and the blade root 90 includes at least one of adhesive bonding, welding, and bolting. Adhesive bonding does not require drilling and does not affect the structural strength of the blade root 90; welding provides a high-rigidity connection; and bolting facilitates disassembly and maintenance, flexibly adapting to different working conditions and balancing structural strength and construction convenience.

[0038] This application provides an installation structure for a wind turbine de-icing system. By optimizing the layout of the support 10, the structure of the anti-torsion bracket 40, the connection method, and the design of the mounting plate, it systematically solves the problems of insufficient installation space and complex construction in existing air-thermal de-icing systems. Its core lies in modular, standardized, and lightweight design, which ensures structural stability while significantly shortening the technical upgrade cycle, making it suitable for rapid retrofitting of different types of wind turbines.

[0039] In some embodiments, OEMs can reserve sufficient installation space and mounting points during the design and manufacturing of the fresh air unit to facilitate the replacement of the corresponding de-icing slip ring (not shown) during the de-icing retrofit of the air unit. Thus, by optimizing the spatial design of the de-icing slip ring installation location, sufficient space is reserved to facilitate the size increase resulting from adding a de-icing slip ring.
