Problems solved by technology

For the existing vertical windmill, although the spiral winding of the blades makes it have a windward side and a leeward side, but because the leeward side bears the wind force with the entire blade, a considerable resistance will be generated. The resistance and the thrust generated by the wind force on the windward side often cancel each other out, resulting in a situation where wind power generation efficiency is low and it is difficult to improve

Embodiment Construction

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0032] First, see figure 1 image 3 As shown, the vertical wind power generation blade of the present invention is mainly composed of a blade frame body 1, a blade main body 2 and a buffer member 3; wherein:

[0033] The blade frame body 1 includes a plurality of sets of vertical plates 11 set up separately from top to bottom, and the sets of vertical plates 11 are arc-shaped, and the two sides of the set of vertical plates 11 are formed with relatively arc-concave windward surfaces 111 and the arc-convex leeward surface 112, and a stopper 12 is set between the upper and lower set of vertical plates 11, and the set of vertical plates 11 is located between the two stoppers 12 to be provided with a pivot hole 113, and the set of...

Abstract

The invention relates to a vertical wind power generation blade. The vertical wind power generation blade comprises assembly plates which are formed on a blade frame body and separated, and a blade main body is pivoted between two separated assembly plates, and a blocking piece is arranged between the assembly plates and the blade main body and performs blocking on one side of the blade main body opposite to the leeward of the assembly plates. Accordingly, the blade main body pivoted to the blade frame body can actively convert the opening and closing state along with wind power orientations of the leeward and the windward side of the blade frame body; when winds blows to the windward side, the blade main body is subjected to blocking location of the blocking piece to be in a closed state so as to enable the blade to completely receive wind power propulsion; when the winds blows to the leeward, the blade main body is in an opened state so as to avoid bearing wind power and generating resistance, so that the problem the wind simultaneously acts on the windward side and the leeward of the blade so that thrust is offset can be effectively solved, and wind power generation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a vertical wind power generation blade, in particular to a vertical wind power generation blade which can effectively prevent wind force from acting on the windward side and the back side of the blade at the same time, so as to greatly improve the efficiency of wind power generation. Background technique [0002] The conversion of wind power into usable energy is mainly through a wind power generating set, which receives wind energy with a windmill and converts it into electricity. It is currently used in wind power generation to transmit aerodynamic force to the generating set Vertical windmills are mainly connected to a rotating shaft with spirally wound blades. Through the design of the blades, the wind acts on the blades, driving the blades to rotate, and the blades are combined with the generator set. The purpose of converting the kinetic energy of the air into electrical energy can be achieved. For the existing vertical ...
