The utility model adopts the design structure of a vertical axis wind turbine. The wind wheel is composed of multiple groups of spiral blades 3 and is arranged around a power generation main shaft 2. Each spiral blade 3 is connected to the power generation main shaft 2 through two groups of connecting plates 4.

As shown in Figure 3, the circulating heat dissipation mechanism of the utility model includes an air inlet hole group and an exhaust hole group 102 opened on a removable cover 101, and the air inlet hole group and the exhaust hole group 102 are respectively located on both sides of the removable cover 101, and a fan 103 is installed in the air inlet hole group. The fan 103 sends external air into the annular cavity of the base box 1, and controls the air to be discharged from the exhaust hole group 102 after circling along the annular cavity. An air guide plate 105 is installed between the air inlet hole group and the exhaust hole group 102, and the air guide plate 105 extends to the inner and outer sides of the base box 1 respectively. The air guide plate located inside the base box 1 prevents hot air from being trapped in the base box 1 for circulation, and the air guide plate located outside the base box 1 prevents the hot air from the exhaust hole group 102 from re-entering the base box 1.

In order to prevent dust from entering the base box 1 , a dustproof net 104 is installed on the outer side of the fan 103 of the utility model.

Example 2

The utility model relates to a wind power generation device that is easy to dissipate heat. Compared with the first embodiment, the utility model has an independent battery installed in the base box 1, the fan 103 is electrically connected to the independent battery, and the independent battery is connected to the generator body. The rest of the structure is the same as the first embodiment.

Example 3
