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 4As shown: on the upper end of a vertical tower rod 1 with a certain height and sufficient strength, a horizontal circular table top 3 with sufficient rigidity is firmly supported by four support rods 2 . A section of vertical cylindrical casing 34 is solidly welded through its round hole in the center of the table panel 3; outside the casing 34, a cylindrical supporting sleeve 36 is supported by a thrust centripetal sliding bearing 35; The outer side of the upper end of the holder sleeve 36 is solidly welded with the lower panel 4 of a partial current wind collecting cover horizontally again, this lower panel 4 should have certain rigidity, and its horizontal profile is like the shape of a javelin head, and the holder sleeve 36 should In conjunction with the center of symmetry plane of lower panel 4—(the tip of the definition javelin head is the front of the bias current wind collecting hood). The upper end of the c...

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 in a vertical state, which can efficiently utilize wind, or similar fluids (such as water bodies 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 windward side of the concave center of the wind rotor blades to catch wind greater than the resistance on the raised leeward side to drive the wind rotor to rotate and drive the generator set to generate electricity. of. 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 b...
