[0026] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0027] according to Figures 1 to 6As shown: This embodiment provides a cooling tower blade assembly structure, including a blade body 200 and a hub 100, the blade body 200 is provided with six groups, and is radially evenly distributed on the outside of the hub 100, and the hub 100 has an axial hole in the middle for connecting and fixing with the driving shaft of the driving motor, wherein the specific implementation structure of the blade body 200 and the hub 100 is described as follows.

[0028] The blade body 200 adopts a shell structure, the interior of the blade body 200 is a cavity, and the end of the blade body 200 is blocked to make the cavity airtight. The blade of this structure has a relatively excellent structural strength compared with the metal panel bending forming, and is not easy to deform during large-angle and high-intensity operations;

[0029] At the root of the blade body 200, there is a mounting portion 301 connected and fixed thereto, the mounting portion 301 and a supporting portion 300 are an integral structure, the mounting portion 301 and the supporting portion 300 themselves have higher structural strength, the supporting portion 300 is located inside the cavity of the blade body 200, and the side surfaces of the supporting portion 300 are contoured surfaces that match the shape of the inner walls of the blade body 200 on both sides, and the side surfaces of the supporting portion 300 are in close contact with the inner walls of the blade body 200 and are fixed by bolts, the bolts are installed along the length direction of the blade body 200, and the length of the supporting portion 300 is close to half the length of the blade to ensure the structural strength and assembly effect of the blade body 200.

[0030] The side of the hub 100 is provided with a mounting seat 101 corresponding to the blade body 200 one by one, and the mounting seat 101 is convexly arranged outwardly with a height of 3-5 cm. The mounting portion 301 is used to be connected and fixed with the mounting seat 101. The mounting seat 101 is provided with a mounting hole 103, and the mounting portion 301 is inserted into the mounting hole 103 and fixed by bolt connection. Through this plug-in structure, rapid assembly between components can be achieved; at the same time, the cross-sections of the mounting hole 103 and the mounting portion 301 are both regular octagonal structures with matching shapes. The regular octagonal structure can realize the installation position of the mounting portion 301 at different angles, that is, the installation angle of the blade body 200. In this way, standardized angle assembly can be achieved, which is easier during the installation process and is suitable for on-site assembly without the need for additional tools for measurement;

[0031] A deflector 102 connected to the wheel hub 100 is provided on the front side of the mounting seat 101 in the rotation direction. The outer surface of the deflector 102 is composed of two symmetrically distributed curved surfaces. One end of the deflector 102 is aligned with the edge of the mounting surface of the mounting seat 101, and the other end of the deflector 102 is aligned with the side of the wheel hub 100. The height of the deflector 102 gradually decreases from one end close to the mounting seat 101 to the other end, so that the deflector 102 can be in relatively gentle contact with the air during the rotation of the wheel hub 100, thereby reducing wind resistance and noise and improving product performance indicators.

[0032] At the same time, after the mounting seat 101 and the blade body 200 are assembled, the root side of the blade body 200 is in contact with the mounting seat 101, thereby reducing the gap between the blade body 200 and the mounting seat 101, making the assembly tighter and the wind resistance lower.

[0033] The above description is only a preferred implementation mode of the present utility model. As long as the technical solution of the purpose of the present utility model is achieved by basically the same means, it belongs to the protection scope of the present utility model.
