Detailed Description

The embodiments are described in detail below with reference to the accompanying drawings.

The embodiment is that one wind wheel is 4 meters high and straightA small and medium flag net wind turbine with the diameter of 5 meters is composed of a central shaft 1, a rotating shaft 2, four-side sails 3 are distributed on the rotating shaft 2 in a cross mode, an upper cross rod, a middle cross rod, a lower cross rod 4 and a rotating shaft 2 are fixedly connected on each sail 3, each cross rod 4 is 2.5 meters long, the distance between the upper cross rod and the lower cross rod 4 is 2 meters, vertical rods 5 are arranged by connecting the upper cross rod and the lower cross rod, hooks 6 are arranged on the upper cross rod and the lower cross rod of each vertical rod 5, blocking nets 7 are vertically and fixedly arranged by connecting the upper cross rod and the lower cross rod 4, and²on the left and right sides, four light and thin windward flags 8 (see attached figure 1) are vertically arranged on each sail 3, each windward flag has an area of 2m high and 1 m wide, and the frontal area is 2m²The windward flag 8 is made of light and thin cloth or plastic film, the upper layer and the lower layer and the inner layer and the outer layer of the four-side windward flag are distributed, the windward flag 8 is respectively arranged at the outer sides of the corresponding blocking nets, (see figure 1), an aluminum wire is used as a flag pole, the windward flag is respectively vertically hung on the upper hook 6 and the lower hook 6 (the vertical rod 5 can also be used as the flag pole), the distance between the inner flag and the outer flag is 1 meter, and the total area of the four-side windward flag on each sail 3 is 8m²On the left and the right, the area of the net is equal, the windward flag +8 of the positive power region is on the windward side of the net, the windward flag-8 of the negative power region is on the leeward side of the net (see figure 1)

The utility model discloses a theory of operation is:

during the operation of the vertical axis flagnet wind turbine, no matter which direction the wind blows, the four windward flags 8 on the wind sail 3 in the negative work area can be unsteadily fluttered along with the wind and only face the wind in the shape of flagtrousers (see the attached

drawings

1, 2 and 8), so that the wind sail 3 in the negative work area only faces the wind in the shapes of net frames and flagtrousers, during the operation, the windward flags-8 also rotate from outside to inside in parallel with the wind direction while revolving, and gradually approach to the corresponding blocking nets, when the windward flags rotate to be parallel with the corresponding blocking nets, the wind force enables the four windward flags to naturally cover the corresponding blocking nets to enter the positive work area, (see the attached drawings 3 and 4) so that the flags and the nets are in a parallel fit combined state, and the four windward flags +8 in the positive work area can all face the wind flags +8 in the shape of 2m due to the supporting action of the blocking nets 7²The positive shape of the wind sail is windward, so that the positive power area wind sail 3 can be formed by combining four windward flags 8 in parallel with a blocking net to form 8m²Due to the use of the sail 3 in the positive power region8m²The left and right wind faces in large area, and the negative power region sail 3 only uses the net rack and the flagon to face the wind, so the windward area of the negative power region sail 3 is relatively small, thereby the windward area proportion of the positive and negative region sails 3 is greatly improved, the windward area of the positive power region can be about 95 times larger than that of the negative power region, when the windward flag of the positive power region runs to the positive and negative junction transition position, the wind force makes the windward flag + -8 leave the corresponding blocking net to turn outwards to enter the state that the negative power region flutters with the wind and only uses the flagon shape to face the wind, the sail 3 running to the negative power region only uses the net rack and the flagon shape to face the wind, thus the positive power region sail 3 can use 8m shape to face with the net rack and the flagon shape continuously circulating²The left and right wind faces in large area, the negative power area sail 3 only faces in small area formed by the flagtrousers and the net rack, and the wind power generation is completed by driving the generator to work through the gear and the variable speed because the positive power area sail 3 faces in large area and is also greatly stressed and the negative power area sail 3 faces in small area and is also slightly stressed, thereby promoting the rotation of the flag net wind turbine.
