[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides a claw-shaped crossbeam of a wind turbine generator which is easy to install. Figures 1-4 As shown, it includes a beam assembly 1, a column 3 is installed at the bottom of the beam assembly 1, a base 4 is installed at the bottom of the column 3, a main box 2 is installed on the beam assembly 1, a clamping assembly 6 is installed on the top of the main box 2, the clamping assembly 6 is connected to the beam assembly 1, a blade 5 is installed at the output end of the main box 2, the beam assembly 1 includes a main beam 11, the main box 2 is installed on the top of the main beam 11, and several sub-beams 12 are installed on both sides of the main beam 11.

[0023] When in use, efficient and stable low-wind-speed power generation is achieved through ingenious structural design. Specifically, the crossbeam is centered on the crossbeam assembly 1, and its bottom is firmly connected to the column 3 and the base 4, forming a solid support structure to ensure the stability of the generator in complex environments. The main box 2 on the crossbeam assembly 1 is responsible for wind power conversion, while the clamping assembly 6 on the top of the main box 2 effectively fixes the main box, enhancing the overall structural rigidity while also simplifying the installation process. In addition, the blades 5 connected to the output end of the main box 2 can efficiently capture low-speed wind energy and convert it into electrical energy.

[0024] The combined design of the main beam 11 and several secondary beams 12 in the crossbeam assembly 1 not only increases the crossbeam's load-bearing capacity but also optimizes the distribution of wind loads, making the crossbeam more stable when subjected to wind forces and extending its service life. This structural design not only improves power generation efficiency but also reduces maintenance costs, bringing significant economic benefits to users.

[0025] In this embodiment, the secondary beams 12 are symmetrically arranged on either side of the main beam 11, with multiple secondary beams 12 on each side arranged at equal intervals. This design effectively balances the force distribution within the crossbeam assembly 1, enhancing the stability and load-bearing capacity of the overall structure. This symmetrical design not only allows the crossbeam to more evenly distribute the load when subjected to wind forces, but also improves the aesthetics of the crossbeam and eases installation, ensuring the stability and durability of the wind turbine over long-term operation.

[0026] Specifically, a slot 13 is provided at the bottom of the main beam 11, into which the top of the column 3 is inserted for a snap-fit ​​connection, achieving a quick and secure connection between the crossbeam assembly 1 and the column 3. This connection method not only simplifies the installation process, reducing installation time and cost, but also improves the reliability and stability of the connection, ensuring the safe operation of the wind turbine in complex environments.

[0027] Furthermore, the clamping assembly 6 includes a main pressure plate 61, which is arranged on the top of the main chassis 2. Insert rods 62 are installed at the bottom of both ends of the main pressure plate 61. The surface of each insert rod 62 is provided with a plurality of through adjustment holes 621, and the adjustment holes 621 are threaded holes. A locking hole 16 is provided at the top of the sub-beam 12 near the insert rod 62. A positioning bolt is installed at the locking hole 16. The end of the positioning bolt slides through the locking hole 16 and is threadedly connected to the adjustment hole 621. By matching the adjustment hole 621 on the surface of the insert rod 62 with the locking hole 16 at the top of the sub-beam 12, and using the positioning bolt for threaded connection, the main chassis 2 is firmly fixed in the upper and lower positions. This design not only enhances the connection strength between the main chassis 2 and the crossbeam assembly 1, but also provides an adjustable fixing method, adapting to main chassis of different sizes and models, and improving the flexibility and applicability of installation.

[0028] Furthermore, the multiple adjustment holes 621 on each insertion rod 62 are arranged vertically at equal intervals, allowing the clamping assembly 6 to have greater adjustment precision and flexibility when securing the main chassis 2. Users can select the appropriate adjustment holes 621 for connection based on their actual needs, ensuring the stability and balance of the main chassis 2 while also facilitating subsequent maintenance and repair work.

[0029] Furthermore, an inner gasket 14 is mounted on the inner side of the subbeam 12, and the subbeam 12 is secured to the inner gasket 14 via locking bolts 15. This invention enhances the structural strength and stability of the subbeam 12. The inner gasket 14 not only provides additional support area but also shares the tightening force of the locking bolts 15, reducing the risk of deformation and damage to the subbeam 12 and extending the service life of the crossbeam.

[0030] Furthermore, the inner sides of the secondary beams 12 on either side and the top of the main beam 11 together form a U-shaped retaining opening. This design not only enhances the overall structural strength of the crossbeam assembly 1 but also provides additional protection for the main chassis 2 and other components. The U-shaped retaining opening effectively limits the displacement and swaying of the main chassis 2, improving the stability and safety of the wind turbine during operation.

[0031] When the claw-shaped crossbeam of the wind turbine of the present invention is in use, wind first strikes blades 5, which, thanks to their unique aerodynamic design, capture the wind energy. This rotational motion of the blades is the starting point for wind power generation. Although not directly mentioned in the description, wind turbines typically include a transmission system to increase speed and transmit torque to the generator within the main chassis 2. Within the main chassis 2, the generator's rotor begins to rotate, converting mechanical energy into electrical energy through the principle of electromagnetic induction.

[0032] The crossbeam assembly 1 serves as the core of the entire structure, with its bottom firmly connected to the columns 3 and base 4, forming a solid support structure that can withstand the various forces and moments generated during the operation of the wind turbine, ensuring stable operation of the generator.

[0033] The combined design of the main beam 11 and several secondary beams 12 not only improves the crossbeam's load-bearing capacity but also optimizes the distribution of wind loads. The secondary beams 12 are symmetrically arranged on either side of the main beam 11, and the multiple secondary beams 12 on each side are evenly spaced. This design effectively balances the force distribution of the crossbeam assembly 1, enhancing the stability and load-bearing capacity of the overall structure.

[0034] The snap-fitting of the slots 13 at the bottom of the main beam 11 and the tops of the columns 3 enables a quick and secure connection between the crossbeam assembly 1 and the columns 3. This connection method simplifies the installation process, reduces installation time and costs, and improves the reliability and stability of the connection.

[0035] The corresponding locking holes 16 and adjustment holes 621 are threadedly connected using positioning bolts. This design not only enhances the connection strength between the main chassis 2 and the crossbeam assembly 1, but also provides an adjustable fixing method. The adjustment holes 62 set in multiple positions are arranged at equal intervals, allowing users to select the appropriate adjustment hole for connection according to actual needs. This design improves the adjustment accuracy and flexibility of the clamping assembly 6 when fixing the main chassis 2, ensures the stability and balance of the main chassis 2, and also facilitates subsequent maintenance and repair work.

[0036] The inner wall of the secondary beam 12 and the top of the main beam 11 together form a U-shaped clamping opening. The main chassis 2 is placed and secured within this U-shaped opening, which not only enhances the overall structural strength of the crossbeam assembly 1 but also provides additional protection for the main chassis 2 and other components. The U-shaped clamping opening effectively limits the displacement and sway of the main chassis 2, improving the stability and safety of the wind turbine during operation.
