Technical Field

[0001] The utility model relates to the technical field of wind wheels, in particular to a full-pressure riveted wind wheel. Background Art

[0002] A wind turbine usually refers to a wind turbine that generates electricity by using wind energy to rotate the generator. Wind turbines are widely used in wind farms and are a source of clean energy. In wind power generation, the design and rotation efficiency of the wind turbine play a vital role in power generation. The design of the wind turbine generally takes into account various factors, including wind speed, blade design, rotor diameter, etc., to maximize power generation efficiency.

[0003] The blades on a traditional wind wheel are usually fixed together by welding or bolts. This method of fixed connection may cause the blades on the wind wheel to be loose when connected, making the blades prone to loosening or falling off during rotation, and may cause the blades to be damaged during rotation, thereby affecting the normal use of the blades. Utility Model Content

[0012] As an optional embodiment, both sides of the blade are wavy

[0013] Beneficial effects of the utility model:

[0014] First, the utility model is provided with a rivet fixing part, which can press one end of the rivet rod into the interior of the rivet sleeve by pressure, and then the rivet screw is threadedly connected with the rivet threaded tube by rotating the rivet screw, so that the two ends of the blade are riveted and fixed to the wind wheel base and the wind wheel disk respectively.
