Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind turbine blade reinforcement device resistant to strong winds. Background Technology
[0002] Wind power generation is a method of generating electricity by converting the kinetic energy of wind into mechanical energy, and then into electrical energy. The equipment required for wind power generation is called a wind turbine generator set (hereinafter referred to as a wind turbine). A wind turbine generator set generally consists of three parts: a wind rotor, a generator, and a tower. The wind rotor mainly consists of a hub and blades. When wind blows onto the blades, the aerodynamic force generated on the blades drives the wind rotor to rotate. A shroud is usually installed on the hub of the blades to reduce the aerodynamic drag on the blades. The blades, the shrouds on their hubs, and related components of the blades and shrouds can be collectively referred to as the blade assembly. Vertical axis wind turbines have many advantages, such as applicability to different wind directions, no noise, and high safety, and represent an important direction for the future development of wind turbines. Existing vertical axis wind turbines generally consist of key components such as blades, transmission systems, and generators. The transmission system inputs the torque from the wind turbine blades to the generator's main shaft, driving the main shaft to rotate and generate electricity. However, current generator blades are mostly fixed by direct connection with fasteners such as bolts. The position and number of connection points are fixed, which may lead to insufficient connection strength in other locations, affecting the normal operation of the blades. Based on this, this application proposes a wind turbine blade reinforcement device that can solve the above problems. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wind turbine blade reinforcement device that can withstand strong winds.
[0004] The purpose of this utility model is achieved through the following technical solution: a wind turbine blade reinforcement device for strong wind resistance, comprising multiple reinforcement base plates, two reinforcement ridges installed on the top surface of each of the multiple reinforcement base plates, an assembly seat slidably installed between the multiple sets of reinforcement ridges, and outer support plates slidably installed on both sides of the outer surface of the multiple reinforcement base plates.
[0005] Optionally, each of the multiple sets of reinforced ridges is provided with a long slot, and each of the multiple assembly seats is provided with a threaded post at one end, and locking caps are threaded on both sides of the outside of the assembly seat, which are located on the outside of the reinforced ridge.
[0006] Optionally, arc grooves are provided on both sides of the outer surface of the multiple reinforced base plates, and arc clamps are installed on one end of the outer support plates, which are slidably engaged with multiple sets of arc clamps.
[0007] Optionally, short slots are provided on the top surface of each of the outer support plates.
[0008] This utility model has the following advantages:
[0009] This wind turbine blade reinforcement device uses a reinforcement base plate as the main body. Two reinforcement ridges are installed on the top surface of the reinforcement base plate to improve the structural strength of the base plate and prevent bending. An assembly base is slidably installed between the two reinforcement ridges, which can combine two adjacent reinforcement base plates together to accommodate blades of different lengths. Arc grooves are opened on both sides of the outer surface of the reinforcement base plate. In use, an outer support plate is installed in the arc groove, which can extend to other positions of the blade to enhance the overall strength of the blade. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.
[0015] like Figures 1 to 3 As shown, a wind turbine blade reinforcement device for strong winds includes multiple reinforcement base plates 1, each with two reinforcement ridges 4 installed on its top surface, assembly seats 3 slidably installed between the multiple sets of reinforcement ridges 4, and outer support plates 2 slidably installed on both sides of the outer surface of the multiple reinforcement base plates 1.

Both sides of its outer side are threaded with locking caps, which are located on the outer side of the reinforcing ridge 4. This facilitates the installation of the assembly seats 3 and allows its installation position to be adjusted according to the actual situation, making it convenient to assemble one or more reinforcing base plates 1 together.
[0017] As an optional technical solution of this utility model, arc grooves 7 are provided on both sides of the outer surface of multiple reinforcing base plates 1, and arc clips 8 are installed on one end of the outer surface of multiple outer support plates 2. They are slidably engaged with multiple sets of arc clips 8, which facilitates the installation of the outer support plates 2 and the reinforcing base plates 1 together, while preventing the outer support plates 2 from falling off accidentally, and the position can be adjusted according to the actual situation.
[0018] As an optional technical solution of this utility model, short slots 9 are provided on the top surfaces of multiple outer support plates 2, which facilitates the use of fasteners to fix the position of the outer support plates 2.
[0019] In summary, the features, assembly methods, usage processes, and functions of each component in this utility model are as follows: A reinforced base plate 1 serves as the main body of the device. Two reinforcing ridges 4 are installed on the top surface of the reinforced base plate 1, which improve the structural strength of the reinforced base plate 1 and prevent bending. An assembly seat 3 is slidably installed between the two reinforcing ridges 4, allowing two adjacent reinforced base plates 1 to be combined together to accommodate blades of different lengths. Arc grooves 7 are provided on both sides of the outer surface of the reinforced base plate 1. During use, an outer support plate 2 is installed within the arc grooves 7, which can extend to other positions on the blade to enhance the overall strength of the blade.
