Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiment is only one embodiment of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] see figure 1 and figure 2 , the embodiments of the present invention include:

[0017] A self-extending vertical axis wind power generator includes a generator 1 , a first bracket 5 , a main shaft 6 , a spoke 7 , a blade 8 , a support rib 9 , a second bracket 10 and a lead screw 11 . The blade 8 has a certain symmetrical airfoil shape, which is parallel to the main shaft 6 and evenly distributed around it. The spokes 7, the main shaft 6 and the blade 8 are connected by hinges. The lead screw 11 is movably mounted on the m...

Abstract

The invention discloses an automatically stretching type vertical-axis wind driven generator comprising a generator, a spindle, a spoke, vanes, a support rib and a screw rod. The screw rod is mounted on the spindle which is connected with the generator, and the vanes are mounted on the spindle through the spoke and connected with the screw rod through the support rib. The automatically stretching type vertical-axis wind driven generator further comprises a support frame, a heavy ball, a gear, an inner sleeve, an outer sleeve, an inner brake and an outer brake, when the wind speed is too high, the heavy ball locks the outer sleeve, the gear drives the screw rod to move downwards, the vanes close up, and the outer brake limits the displacement of the screw rod; when the speed is too low, the heavy ball lock the inner sleeve, the gear drives the screw rod to move upwards, the vanes expand, and the inner brake limits the displacement of the screw rod. The automatically stretching type vertical-axis wind driven generator is driven without a motor, vanes' sweeping area is decreased automatically when wind speed is too high and increased automatically when wind speed is too low, the generating capacity of the vertical-axis wind driven generator is increased, safe and stable running of the vertical-axis wind driven generator is guaranteed.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a self-extending vertical axis wind power generator. Background technique [0002] With the development of renewable energy technologies such as wind power generation, vertical axis wind turbines have achieved remarkable development in recent years because vertical axis wind turbines do not require wind devices. The swept area of ​​the existing vertical axis wind turbine blades is generally not adjustable, and it is difficult to adapt to a wide wind speed range. [0003] The extensible vertical axis wind turbines disclosed in the prior art are generally equipped with a control motor, which drives the lead screw to rotate, adjusts the sweep area of ​​the blades, and stabilizes the power near the rated power. Since the control motor consumes electricity, when the wind is unstable, the control motor needs to be started frequently, which wastes energy. Therefore, the disadvanta...
