Description

Technical Field

[0001] This utility model relates to a wind turbine for a wind power generator, belonging to the field of wind turbine technology. Background Technology

[0002] In some icy regions, the blades of wind turbines can freeze, affecting normal operation and necessitating de-icing. One de-icing method involves installing a fan at the root of the blade. The air blown by the fan is heated by a heating device and continuously blown into the cavity of the blade, raising the internal temperature and preventing or removing ice. As wind power generation capacity increases, blade length also increases, requiring larger turbines to achieve the desired wind delivery. However, large turbines are difficult to install due to limitations in blade opening size. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a wind turbine for a wind power generator. The wind turbine casing adopts an upper and lower splicing structure, which can be installed in the wind turbine blade through a small blade opening, thus overcoming the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a wind turbine for a wind turbine generator, which is installed inside the blades of a wind turbine generator by a support, and includes a volute with an air inlet and an impeller mounting port, an impeller installed in the volute through the impeller mounting port, and a motor for driving the impeller to rotate. The volute includes a matching upper half and a lower half, and the upper half and the lower half each include half of the air inlet and the impeller mounting port.

[0005] Further, it includes a bracket, the volute is mounted on the bracket, the bracket and the support are provided with corresponding connecting grooves, and the fasteners are connected through the connecting grooves to fix the bracket on the support. The corresponding connecting grooves are a transverse groove and a longitudinal groove.

[0006] Furthermore, an air guide ring is installed at the air inlet, which extends into the volute and connects to the impeller. The bracket, air guide ring, and lower half of the volute are connected and fixed by fasteners to form a pre-assembled component.

[0007] Furthermore, the air guide ring, bracket and upper body are provided with corresponding connection holes. After the upper body and lower body are installed and matched, the upper body is aligned with the corresponding connection holes on the air guide ring and bracket.

[0008] Furthermore, the bracket includes bent sheet metal parts fixed to both sides of the volute, and the bent sheet metal parts are hollowed out.

[0009] By implementing this utility model, the fan casing is designed and manufactured in two halves, upper and lower. During installation, the upper and lower halves of the casing are respectively inserted into the blades through the blade openings and assembled inside the blades. This allows for the convenient installation of large-sized fans inside the blades through smaller blade openings, thereby enabling high-power fans to achieve the desired air delivery effect.

[0015] Embodiments of this utility model: such as Figures 1 to 4 As shown, a wind turbine for a wind power generator is installed inside the blades of a wind power generator via a support 1 and connected to a heater 12. It includes a volute 3 with an air inlet 2 and an impeller mounting port 11, an impeller mounted on the volute 3 via the impeller mounting port 11, and a motor 10 that drives the impeller to rotate. The air inlet 2 and the impeller mounting port are located on opposite sides of the volute 3. The volute 3 includes a matching upper half 4 and a lower half 5, each containing half of the air inlet 2 and the impeller mounting port. The wind turbine volute 3 is designed and manufactured in two parts: the upper half 4 and the lower half 5. During installation, the upper half 4 and the lower half 5 respectively enter the blades through the blade openings and are assembled inside the blades. This allows for the convenient installation of a large-sized wind turbine inside the blades through relatively small blade openings, thus enabling a high-power wind turbine to achieve the desired air delivery effect.

[0016] As a preferred embodiment, the bracket 6 is included, and the volute 3 is mounted on the bracket 6. The bracket 6 and the support 1 are provided with corresponding connecting grooves 7. Fasteners are connected through the connecting grooves 7 to fix the bracket 6 to the support 1. The corresponding connecting grooves 7 are a transverse groove and a longitudinal groove, respectively. For example, in this application, the connecting groove 7 on the bracket 6 is a transverse groove, and the corresponding connecting groove 7 on the support 1 is a longitudinal groove. Bolts pass through the connecting grooves 7 of both and are connected to nuts for fixation. When the bracket 6 moves laterally or longitudinally relative to the support 1 within a certain range, the connecting grooves 7 will intersect, and the bolts can pass through the intersection of the two and be connected to nuts for fixation. This allows the installation position of the volute 3 on the support 1 to be adjusted so that it can be accurately connected to the heater.

[0017] As a preferred embodiment, an air guide ring 8 is installed at the air inlet 2. The air guide ring 8 extends into the volute 3 and connects to the impeller. The bracket 6, air guide ring 8, and lower half of the volute 5 are connected and fixed by fasteners to form a pre-assembled component. The air guide ring 8 allows the airflow to enter the impeller more smoothly and accelerates the flow, thereby improving the air volume and efficiency of the fan. The bracket 6, air guide ring 8, and lower half of the volute 4 are provided with aligned connecting holes. The three are connected together by bolts to form a pre-assembled component. During installation, the pre-assembled component consisting of the three is installed on the support 1, and then the upper half 4 and the lower half 5 are connected to complete the installation of the volute 3, which is convenient for installation.

[0018] As a preferred embodiment, the air guide ring 8, the bracket 6, and the upper body 4 are provided with corresponding connection holes. Specifically, the air guide ring 8 and the upper body 4 are provided with corresponding connection holes on one side, and the upper body 4 and the bracket 6 are provided with corresponding connection holes on the other side. After the upper body 4 and the lower body 5 are installed and fitted, the connection holes on both sides of the upper body 4 are aligned with the connection holes on the air guide ring 8 and the bracket 6, and then bolts are used to connect and fix them. The upper body 4 and the lower body 5 are connected by bolts to fix the volute 3 longitudinally, and to the air guide ring 8 and the bracket 6 to fix it laterally, thereby increasing the stability after installation.

[0019] As a preferred embodiment, the bracket 6 includes bent sheet metal parts 9 fixed to both sides of the volute 3. The bent sheet metal parts 9 are hollowed out, and the connecting holes aligned with the volute 3 are located on the bent sheet metal parts 9. The bent sheet metal parts 9 on both sides are connected to the volute 3 and then to the support 1 to provide support to both sides of the volute 3. The hollowing out process reduces weight without affecting strength.
