Problems solved by technology

This type of wind power generator still consumes a lot of wind energy captured by the concave center surface of the blade because the raised leeward surface of the blade still bears the resistance of the gas on the projected surface of the wind direction. In addition, in order to reduce the resistance on the leeward side of the blades of the wind rotor, the blades of the wind rotor are all made into a narrow shape of a "scimitar willow leaf", which greatly weakens the wind-catching ability of the blades. capacity, which greatly limits its installed capacity

Embodiment Construction

[0022] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown: at the upper end of a vertical tower pole 1 with a certain height and sufficient strength, a horizontal circular countertop 3 with sufficient rigidity is firmly supported by four support poles 2. A vertical cylindrical sleeve 34 is fixedly welded to the center of the countertop 3 through its circular hole; on the outside of the sleeve 34, a cylindrical bracket 36 is supported by a thrust centripetal sliding bearing 35; The outer side of the upper end of the bracket 36 is horizontally fixedly welded to a lower panel 4 of the deflector wind collecting hood. The lower panel 4 should have a certain rigidity, and its horizontal shape is like a javelin head, and the bracket 36 should It is combined on the symmetrical center plane of the lower panel 4—(hereby define the tip of the javelin head as the front of the deflector wind collecting hood). At the upper end of the sleeve 34, the axial movement of the bracket 36 is ...

Abstract

The invention discloses a horizontal-axis wind turbine. Resistance of one side of the leeside of wind turbine blades is totally shielded through a bias current wind collection cover widely collecting wind sources and a flow guiding inclined plate, the resistance is converted into power, the strong wind catching ability and the throat effect of the wind turbine blades are achieved at the same time, the rigidity, the intensity and the speed of airflow on wind wheel pushing force is greatly intensified, namely, and the wind power utilization rate and the low velocity wind source utilization ability are greatly intensified; symmetrical wind wheels arranged in parallel can double the installed capacity; a wing-shaped force lifting plate wind speed self control device can prevent the electric power damage to equipment by high-speed airflows, and meanwhile the high speed wind source utilization span is also increased greatly.

Description

(1) Technical field [0001] A wind power generator, especially a wind power generator whose rotor shaft is vertical. It can efficiently use wind or similar fluids (such as water in rivers, rivers, or ocean currents..... Etc.) to generate electricity for people. (2) Background technology [0002] The current vertical axis wind turbines use the pressure difference generated by the wind-catching ability of the concave windward surface of the rotor blades to be greater than the resistance received by the convex leeward surface to drive the rotor to rotate and drive the generator set to generate electricity of. In this type of wind turbine, the convex leeward surface of its blades will still bear the resistance of gas on the projection surface of the wind direction, so the wind energy captured by the concave core surface of the blades is still consumed greatly. In addition, in order to reduce the resistance of the leeward side of the blades of the wind wheel, the blades of the wind w...
