Embodiment 1
[0043] This is a vertical axis wind energy device with variable distance and variable angle. The basic structure includes at least a power shaft 1, a blade 3, a blade shaft 4, and a generator 2 driven by the power shaft. figure 1 , figure 2It can be seen from the above that, in the device mentioned in this description, some other auxiliary components are not involved, such as the bracket of the vertical axis wind energy device, etc., because they have no influence on the essence of the invention, so there is no too much description.
[0044] Such as Figure 1 to Figure 4 As shown, the blade shaft is arranged horizontally and horizontally, and the center of the blade shaft 4 is vertically intersected with the power shaft or the extension line of the power shaft 1. This setting can maximize the efficiency and avoid the generation of eccentric moment. Blade 3, and both are fixedly arranged, and blade 3 is the main component that is subjected to wind force or hydraulic force, as...
Embodiment 2
[0056] The basic structure and principle are the same as above, the difference is that at least one of the blade and the blade shaft has a limiting device, and the angle range of the blade rotation is limited from the horizontal direction to the vertical upward range of about 90 degrees, with the rotation of the power shaft Different angles have different states of horizontal and vertical, such as Figure 9 As shown, in this case, the blade 3 is above the blade shaft 4, and figure 2 As shown, the position of the blade 3 is higher, so that the wind energy utilized is more sufficient and the efficiency is higher.
Embodiment 3
[0058] This is a vertical axis wind energy device with variable distance and angle, at least including power shaft 1, blade 3, and blade shaft 4. It is basically the same as the previous implementation. Or the extension line of power axis 1 intersects perpendicularly, such as Figure 10 , Figure 11 As shown, if the blade shaft 4 does not pass through the axis and extension line of the power shaft 1, a blade 3 is arranged at one end of the blade shaft 4; the blade 3 is arranged on one side of the end of the blade shaft 4, and is assembled with a bearing 51 to form Driving torque on one side; a blade group is composed of a blade shaft 4 and blades 3 at one end, with at least three or more blade groups, which are evenly distributed in the rotation plane of the power shaft 1, forming a work perpendicular to the power shaft noodle.
