Power generation efficiency.

2. The blade joint is sleeved on the moving section, and the blade wind position can be freely adjusted. No power and complicated control device are needed, and the component wind action position can be easily changed without excessive disassembly of the component action. Adjust the speed of the rotor seat to change the power generation efficiency of the generator set.

In light of the above technical features, the main effects of the wind power generating apparatus of the present invention which can automatically adjust the position of the blade will be clearly shown in the following embodiments.

An embodiment of the wind power generator capable of automatically adjusting the position of the blade of the present invention, as shown in the first figure, comprises: a generator set (1), at least one fixed rod (2), at least one blade (3) and one Automatic mechanism (4), where:

The generator set (1) comprises a body (11), a stator rod (12) and a rotor seat (13). The seat body (11) is connected to the stator rod (12), and the rotor seat (13) is opposite The stator rod (12) is rotated to generate electricity for supply.

The fixing rods (2) are disposed on the rotor seat (13), and each of the fixing rods (2) is provided with at least one moving section (21).

The blade (3) is movably fixed to the fixing rod (2). The blade (3) is provided with a joint portion (31) at one end and a fixing portion (32) at the other end. The joint portion (32) is sleeved on the joint portion (32). On the moving section (21), the blade (3) is movably displaced along the moving section (21), the blade (3) is a rigid sheet, and the joint (31) is a rigid sleeve.

Continuing to refer to the fifth figure, the automatic mechanism (4) includes a groove (41), an axle (42), a rope (43), a slider (44) and a spring (45). 41) is provided for the fixing portion (32) of the blade (3), the rope (43) is passed through the fixing portion (32) and is respectively connected to the axle (42), the slider (44) and the spring ( 45).

Continuing to refer to the first figure and in conjunction with the third and fifth figures, in use, the blade (3), when subjected to a wind force (A), rotates the rotor seat (13) relative to the stator rod (12). The generator set (1) generates electricity, further illustrating that the rotation speed of the rotor seat (13) relative to the stator rod (12) depends on the size of the wind (A) and a force arm (B) The length. Therefore, when the wind force (A) becomes large, the slider (44) moves away from the stator rod (12) due to the influence of the centrifugal force, thereby driving the axle (42) to actuate the rope (43). The fixing portion (32) for pulling the blade (3) moves from the groove (41) toward the stator rod (12), in order to avoid damage caused by the rotation speed of the rotor seat (13) being too fast, so The automatic mechanism (4) automatically adjusts the position of the blade (3) relatively close to the stator bar (12) on the moving section (21), so that the length of the arm (B) is shortened, even in the wind When it becomes larger, the rotational speed of the rotor seat (13) can still be made constant, and the generator set (1) is maintained to a normal power generation efficiency, whereby the rotor seat (13) can be avoided due to the blade (3) The wind (A) becomes large and the rotation is too fast to cause damage.

Continuing to refer to the second figure and in conjunction with the fourth and sixth figures, similarly, when the wind (A) becomes small, the slider (44) approaches the stator rod (12) due to less influence of centrifugal force. Moving in the direction, thereby driving the axle (42) to move the rope (43) to pull the fixing portion (32) of the blade (3) from the groove (41) away from the stator rod (12) for stabilization The rotation speed of the rotor seat (13), so that the automatic mechanism (4) can automatically adjust the position of the blade (3) on the moving section (21) relatively far from the stator pole (12), so that the force arm ( The length of B) becomes long, and even when the wind force becomes small, the rotational speed of the rotor seat (13) can be made constant, and the generator set (1) can be maintained to a normal power generation efficiency, thereby avoiding the The rotor seat (13) is inefficient in power generation of the generator set (1) because the blade (3) is subjected to the wind (A) becoming smaller and the rotation is slower.

Since the blade (3) of the present invention is a vertical axis design, the blade (3) rotates around the stator rod (12), and the blade (3) can receive wind from all directions without adjusting the wind direction, and the structure It's simpler and the price is cheaper. The number of the blades (3) also affects the wind force, and the number of the blades (3) is optimally 4-5 pieces. In the present embodiment, the number of the adjustment sheets (23) is exemplified by four pieces.

In view of the above description of the embodiments, the above-described embodiments are merely a preferred embodiment of the present invention, and the implementation of the present invention is not limited thereto. The scope, that is, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the creation of the creation, are within the scope of this creation.
